背景技术Background Art

随着锂电行业的飞速发展，动力电芯的生产效率要求越来越高，并且生产成本需要大幅降低，对于单体电芯生产的能耗要求越来越低。而化成工序由于需要在高温环境下使电池内部生成SEI（Solid Electrolyte Interface membrane，固体电解质界面膜）膜，因此高温化成被广泛应用于方形锂离子电芯的生产过程。With the rapid development of the lithium battery industry, the production efficiency requirements for power batteries are getting higher and higher, and the production costs need to be greatly reduced, and the energy consumption requirements for the production of single batteries are getting lower and lower. Since the formation process needs to generate the SEI (Solid Electrolyte Interface membrane) film inside the battery under high temperature environment, high-temperature formation is widely used in the production process of square lithium-ion batteries.

但是，在相关技术中，高温化成工序由于需要给常温状态下的电芯进行加热，因此增加了化成间的能源损耗。However, in the related art, the high-temperature formation process requires heating the battery cells at room temperature, thus increasing the energy loss during the formation process.

例如，辅助设备可以包括厂房的热泵。例如，如图1所示，该辅助设备包括：第二风扇101、第二换热器102、压缩机103、膨胀阀104、单向阀105、过滤器106、第三换热器107、泵108、热水箱109、第一阀门110a和第二阀门110b。第二换热器102设置在厂房10中。第二换热器102与压缩机103通过第一管路连接。第二换热器102与第三换热器107通过第二管路连接。膨胀阀104、单向阀105和过滤器106设置在该第二管路上。压缩机103与第三换热器107通过第三管路连接。第三换热器107与热水箱109通过第四管路连接，泵108设置在该第四管路上。第三换热器107与热水箱109还通过第五管路连接，第一阀门110a设置在该第五管路上。热水箱109还连接有第一主管路111和第二主管路112。例如，第二阀门110b设置在第二主管路112上。第一主管路111通过第一支管路113连接到第一换热器210，第二主管路112通过第二支管路114连接到第一换热器210。For example, the auxiliary equipment may include a heat pump of a plant. For example, as shown in FIG1 , the auxiliary equipment includes: a second fan 101, a second heat exchanger 102, a compressor 103, an expansion valve 104, a check valve 105, a filter 106, a third heat exchanger 107, a pump 108, a hot water tank 109, a first valve 110a, and a second valve 110b. The second heat exchanger 102 is arranged in the plant 10. The second heat exchanger 102 is connected to the compressor 103 through a first pipeline. The second heat exchanger 102 is connected to the third heat exchanger 107 through a second pipeline. The expansion valve 104, the check valve 105, and the filter 106 are arranged on the second pipeline. The compressor 103 is connected to the third heat exchanger 107 through a third pipeline. The third heat exchanger 107 is connected to the hot water tank 109 through a fourth pipeline, and the pump 108 is arranged on the fourth pipeline. The third heat exchanger 107 is also connected to the hot water tank 109 through a fifth pipeline, and the first valve 110a is disposed on the fifth pipeline. The hot water tank 109 is also connected to a first main pipeline 111 and a second main pipeline 112. For example, the second valve 110b is disposed on the second main pipeline 112. The first main pipeline 111 is connected to the first heat exchanger 210 through a first branch pipeline 113, and the second main pipeline 112 is connected to the first heat exchanger 210 through a second branch pipeline 114.

例如，如图1所示，上述辅助设备即为厂房的制冷系统，该制冷系统采用一种大型热泵。此种热泵可以提供整个厂房大部分区域的制冷。厂房级别的压缩机103提供系统动力，将制冷媒通过制冷端的第二换热器102，通过厂房10的第二风扇101将冷量带入到厂房各个区域，图1中示出了热空气121和冷空气122，升温后的冷媒通过压缩机到达换热器进行热冷交换，冷媒降温后通过过滤器106、单向阀105、膨胀阀104后降低温度。其中膨胀阀104与单向阀105为并联连接方式。第三换热器107的热量通过泵108交换到热水箱109，将热能存储到散热系统中。将散热系统中的一部分热量引入到化成管路系统中，通过管路将热水引入到化成机的压床腔311至少一侧的第一换热器210中（例如，第一换热器210的进水温度的范围为49℃至100℃，回水温度为47℃），利用换热腔中的第一风扇220将热能输送到压床腔311，从而提高压床腔的温度。For example, as shown in FIG1 , the auxiliary equipment is the refrigeration system of the plant, which uses a large heat pump. This heat pump can provide refrigeration for most areas of the entire plant. The plant-level compressor 103 provides system power, passes the refrigerant through the second heat exchanger 102 at the refrigeration end, and brings the cold air into various areas of the plant through the second fan 101 of the plant 10. FIG1 shows hot air 121 and cold air 122. The heated refrigerant reaches the heat exchanger through the compressor for heat-cold exchange. After the refrigerant cools down, it passes through the filter 106, the one-way valve 105, and the expansion valve 104 to reduce the temperature. The expansion valve 104 and the one-way valve 105 are connected in parallel. The heat of the third heat exchanger 107 is exchanged to the hot water tank 109 through the pump 108, and the heat energy is stored in the heat dissipation system. A portion of the heat in the heat dissipation system is introduced into the formation piping system, and hot water is introduced into the first heat exchanger 210 on at least one side of the press chamber 311 of the formation machine through the pipeline (for example, the water inlet temperature of the first heat exchanger 210 ranges from 49°C to 100°C, and the return water temperature is 47°C), and the first fan 220 in the heat exchange chamber is used to transport heat energy to the press chamber 311, thereby increasing the temperature of the press chamber.

这里，换热器中通入热水，冷空气从压床腔的上部流入到换热腔的上部，冷空气通过换热器加热后由风扇吹出，热空气从托盘的侧面或者底面吹入压床腔中形成完整循环。例如，风扇的总风量2688m³/h（立方米/小时），压床腔的容积为2.2 m³，则换风次数为2688/2.2=1221次/h。Here, hot water is introduced into the heat exchanger, cold air flows into the upper part of the press cavity from the upper part of the heat exchange cavity, the cold air is heated by the heat exchanger and blown out by the fan, and the hot air is blown into the press cavity from the side or bottom of the tray to form a complete cycle. For example, the total air volume of the fan is ^2688m3 /h (cubic meters/hour), and the volume of the press cavity is ^2.2m3 , then the number of air changes is 2688/2.2=1221 times/h.

需要说明的是，图1中示出的辅助设备的结构仅是示例性的，本公开的实施例可以采用其他类型的辅助设备，因此，本公开的范围并不限于这里公开的辅助设备的结构。It should be noted that the structure of the auxiliary device shown in FIG. 1 is merely exemplary, and the embodiments of the present disclosure may adopt other types of auxiliary devices. Therefore, the scope of the present disclosure is not limited to the structure of the auxiliary device disclosed herein.

图2中示出了进风方向411和出风方向412。例如，进风温度为25℃，出风温度的范围为42℃至45℃。如图2所示，压床腔311内放置托盘401。例如，托盘401位于压床腔的中部。托盘内部放置电芯。例如，该托盘可以每2.5小时进出压床腔一次，压床腔每次开门0.5分钟。这样方便进行后续的化成工序。FIG2 shows an inlet direction 411 and an outlet direction 412. For example, the inlet temperature is 25°C, and the outlet temperature ranges from 42°C to 45°C. As shown in FIG2 , a tray 401 is placed in the press chamber 311. For example, the tray 401 is located in the middle of the press chamber. The battery cells are placed inside the tray. For example, the tray can enter and exit the press chamber once every 2.5 hours, and the press chamber is opened for 0.5 minutes each time. This facilitates the subsequent formation process.

至此，提供了根据本公开一些实施例的用于化成机的加热系统，其中，化成机包括一个或多个压床柜，每个压床柜包括压床腔和在压床腔至少一侧的换热腔，加热系统包括：换热器，设置在换热腔中，用于利用来自于辅助设备的热量对换热腔内的空气加热；和风扇，设置在换热腔中，用于将加热后的空气输送至压床腔中。通过设置在压床柜的换热腔中的换热器，利用来自于辅助设备的热量对换热腔内的空气加热，并利用风扇将加热后的空气输送至压床腔中，这样方便在压床腔内进行化成工序，由于换热器是利用辅助设备的热量对空气进行加热的，即，可以利用废热能源加热化成设备，使电芯达到工艺温度，因此可以节省能源消耗。例如，废热能源设备可以包括厂房的制冷系统，如前所述，该制冷系统采用一种大型热泵。So far, a heating system for a chemical forming machine according to some embodiments of the present disclosure is provided, wherein the chemical forming machine includes one or more press cabinets, each press cabinet includes a press chamber and a heat exchange chamber on at least one side of the press chamber, and the heating system includes: a heat exchanger, arranged in the heat exchange chamber, for heating the air in the heat exchange chamber using the heat from the auxiliary equipment; and a fan, arranged in the heat exchange chamber, for conveying the heated air to the press chamber. By means of a heat exchanger arranged in the heat exchange chamber of the press cabinet, the air in the heat exchange chamber is heated using the heat from the auxiliary equipment, and the heated air is conveyed to the press chamber using the fan, so that it is convenient to carry out the chemical forming process in the press chamber, because the heat exchanger heats the air using the heat from the auxiliary equipment, that is, the waste heat energy can be used to heat the chemical forming equipment so that the battery core reaches the process temperature, thereby saving energy consumption. For example, the waste heat energy equipment may include a refrigeration system of a plant, as mentioned above, the refrigeration system adopts a large heat pump.

需要说明的是，每个换热腔内的换热器的数量和风扇的数量可以根据需要来设置。例如，每个换热器内设置1个换热器和4个风扇。本公开的范围并不限于换热器和风扇的具体数量。It should be noted that the number of heat exchangers and fans in each heat exchange chamber can be set as needed. For example, one heat exchanger and four fans are set in each heat exchanger. The scope of the present disclosure is not limited to the specific number of heat exchangers and fans.

如图2所示，第一换热器210位于第一换热腔321（或第二换热腔322）的上部，第一风扇220位于第一换热腔321（或第二换热腔322）的下部。这样可以合理安排换热器和风扇的位置，方便加热换热腔内的空气，并方便将加热后的空气输送到压床腔中。As shown in Fig. 2, the first heat exchanger 210 is located at the upper part of the first heat exchange cavity 321 (or the second heat exchange cavity 322), and the first fan 220 is located at the lower part of the first heat exchange cavity 321 (or the second heat exchange cavity 322). In this way, the positions of the heat exchanger and the fan can be reasonably arranged, which is convenient for heating the air in the heat exchange cavity and convenient for conveying the heated air to the press cavity.

例如，如图2所示，换热腔包括位于换热腔的上部的第一通风口331和位于换热腔的下部的第二通风口332，第一通风口331和第二通风口332分别将第一换热腔321（或第二换热腔322）与压床腔311连通。第一换热器210位于第一换热腔321（或第二换热腔322）的上部，且靠近第一通风口331，第一风扇220位于第一换热腔321（或第二换热腔322）的下部，且靠近第二通风口332。这样可以方便加热换热腔内的空气，并方便将加热后的空气输送到压床腔中，从而方便进行化成工序。For example, as shown in FIG. 2 , the heat exchange chamber includes a first vent 331 located at the upper part of the heat exchange chamber and a second vent 332 located at the lower part of the heat exchange chamber, and the first vent 331 and the second vent 332 respectively connect the first heat exchange chamber 321 (or the second heat exchange chamber 322) with the press chamber 311. The first heat exchanger 210 is located at the upper part of the first heat exchange chamber 321 (or the second heat exchange chamber 322) and is close to the first vent 331, and the first fan 220 is located at the lower part of the first heat exchange chamber 321 (or the second heat exchange chamber 322) and is close to the second vent 332. In this way, it is convenient to heat the air in the heat exchange chamber and to transport the heated air to the press chamber, thereby facilitating the formation process.

如图2所示，冷空气从换热腔的顶部流入，冷空气通过第一换热器210进行加热后流过第一风扇220，加热后的空气通过第一风扇220流出第一换热腔321（或第二换热腔322）。流出换热腔的热空气流到托盘401底部，至下而上的对托盘进行加热，这样方便在压床腔内进行化成工序。As shown in FIG2 , cold air flows in from the top of the heat exchange chamber, is heated by the first heat exchanger 210, and then flows through the first fan 220. The heated air flows out of the first heat exchange chamber 321 (or the second heat exchange chamber 322) through the first fan 220. The hot air flowing out of the heat exchange chamber flows to the bottom of the tray 401, and heats the tray from bottom to top, which facilitates the formation process in the press chamber.

在一些实施例中，如图2所示，换热腔包括第一换热腔321和第二换热腔322。第一换热腔321位于压床腔311的第一侧，第二换热腔322位于压床腔311的第二侧，第二侧与第一侧相对。每个压床腔内均设置第一换热器210和第一风扇220。这样，通过在压床腔的两侧分别设置一个换热腔，可以更快且更均匀地提高压床腔内的温度，方便进行化成工序。In some embodiments, as shown in FIG. 2 , the heat exchange chamber includes a first heat exchange chamber 321 and a second heat exchange chamber 322. The first heat exchange chamber 321 is located on the first side of the press chamber 311, and the second heat exchange chamber 322 is located on the second side of the press chamber 311, and the second side is opposite to the first side. A first heat exchanger 210 and a first fan 220 are provided in each press chamber. In this way, by providing a heat exchange chamber on both sides of the press chamber, the temperature in the press chamber can be increased more quickly and evenly, which facilitates the formation process.

在一些实施例中，第一换热腔321（或第二换热腔322）为压强恒定的腔室（即，静压间）。这样可以使得换热腔内的加热后的空气能够更加均匀地输送到压床腔内。In some embodiments, the first heat exchange chamber 321 (or the second heat exchange chamber 322) is a chamber with a constant pressure (ie, a static pressure chamber), so that the heated air in the heat exchange chamber can be more evenly transported to the press chamber.

图2示出了第一换热器210和第一风扇220的位置布置，但是这仅是示例性的，实际上，第一换热器210和第一风扇220也可以按照其他的位置进行布置，后面结合其他附图进行描述。FIG2 shows the positional arrangement of the first heat exchanger 210 and the first fan 220 , but this is merely exemplary. In fact, the first heat exchanger 210 and the first fan 220 may also be arranged at other positions, which will be described later in conjunction with other drawings.

图3是示意性地示出根据本公开另一些实施例的用于化成机的加热系统的主视图。FIG. 3 is a front view schematically showing a heating system for a forming machine according to other embodiments of the present disclosure.

如图3所示，第一换热器210位于第一换热腔321（或第二换热腔322）的下部，第一风扇220位于第一换热腔321（或第二换热腔322）的上部。这样可以合理安排换热器和风扇的位置，方便加热换热腔内的空气，并方便将加热后的空气输送到压床腔中。As shown in Fig. 3, the first heat exchanger 210 is located at the lower part of the first heat exchange cavity 321 (or the second heat exchange cavity 322), and the first fan 220 is located at the upper part of the first heat exchange cavity 321 (or the second heat exchange cavity 322). In this way, the positions of the heat exchanger and the fan can be reasonably arranged, which is convenient for heating the air in the heat exchange cavity and convenient for conveying the heated air to the press cavity.

例如，如图3所示，第一换热器210位于第一换热腔321（或第二换热腔322）的下部，且靠近第二通风口332，风扇位于第一换热腔321（或第二换热腔322）的上部，且靠近第一通风口331。这样可以方便加热换热腔内的空气，并方便将加热后的空气输送到压床腔中，从而方便进行化成工序。For example, as shown in FIG3 , the first heat exchanger 210 is located at the lower part of the first heat exchange cavity 321 (or the second heat exchange cavity 322) and is close to the second vent 332, and the fan is located at the upper part of the first heat exchange cavity 321 (or the second heat exchange cavity 322) and is close to the first vent 331. This makes it convenient to heat the air in the heat exchange cavity and to transport the heated air to the press cavity, thereby facilitating the formation process.

图4是示意性地示出根据本公开另一些实施例的用于化成机的加热系统的主视图。FIG. 4 is a front view schematically showing a heating system for a forming machine according to other embodiments of the present disclosure.

如图4所示，第一换热器210位于第一换热腔321（或第二换热腔322）的中部，第一风扇220位于第一换热腔321（或第二换热腔322）的上部。例如，第一风扇220靠近第一通风口331。这样可以合理安排换热器和风扇的位置，方便加热换热腔内的空气，并方便将加热后的空气输送到压床腔中。As shown in FIG4 , the first heat exchanger 210 is located in the middle of the first heat exchange cavity 321 (or the second heat exchange cavity 322), and the first fan 220 is located in the upper part of the first heat exchange cavity 321 (or the second heat exchange cavity 322). For example, the first fan 220 is close to the first vent 331. In this way, the positions of the heat exchanger and the fan can be reasonably arranged, which is convenient for heating the air in the heat exchange cavity and for conveying the heated air to the press cavity.

例如，第一换热器210为板状换热器。第一换热腔321（或第二换热腔322）内的空气的流动方向垂直于板状换热器，如图4所示。这样方便换热器与换热腔内的空气进行比较充分的热量交换，从而比较快地加热空气。For example, the first heat exchanger 210 is a plate heat exchanger. The air in the first heat exchange cavity 321 (or the second heat exchange cavity 322) flows perpendicular to the plate heat exchanger, as shown in FIG4. This facilitates a relatively sufficient heat exchange between the heat exchanger and the air in the heat exchange cavity, thereby heating the air relatively quickly.

图5是示意性地示出根据本公开另一些实施例的用于化成机的加热系统的主视图。FIG. 5 is a front view schematically showing a heating system for a forming machine according to other embodiments of the present disclosure.

如图5所示，第一换热器210位于第一换热腔321（或第二换热腔322）的中部，第一风扇220位于第一换热腔321（或第二换热腔322）的下部。例如，第一风扇220靠近第二通风口332。这样可以合理安排换热器和风扇的位置，方便加热换热腔内的空气，并方便将加热后的空气输送到压床腔中。As shown in FIG5 , the first heat exchanger 210 is located in the middle of the first heat exchange cavity 321 (or the second heat exchange cavity 322), and the first fan 220 is located in the lower part of the first heat exchange cavity 321 (or the second heat exchange cavity 322). For example, the first fan 220 is close to the second vent 332. In this way, the positions of the heat exchanger and the fan can be reasonably arranged, which is convenient for heating the air in the heat exchange cavity and for conveying the heated air to the press cavity.

例如，第一换热器210为板状换热器。第一换热腔321（或第二换热腔322）内的空气的流动方向垂直于板状换热器，如图5所示。这样方便换热器与换热腔内的空气进行比较充分的热量交换，从而比较快地加热空气。For example, the first heat exchanger 210 is a plate heat exchanger. The air in the first heat exchange cavity 321 (or the second heat exchange cavity 322) flows perpendicular to the plate heat exchanger, as shown in FIG5. This facilitates a relatively sufficient heat exchange between the heat exchanger and the air in the heat exchange cavity, thereby heating the air relatively quickly.

需要说明的是，本公开实施例中的换热器除了采用板状换热器，也可以采用其他类型的换热器，因此，本公开的范围并不限于换热器的具体类型。It should be noted that, in addition to the plate heat exchanger, the heat exchanger in the embodiment of the present disclosure may also be other types of heat exchangers. Therefore, the scope of the present disclosure is not limited to the specific type of heat exchanger.

还需要说明的是，图2至图5所示的加热系统的结构中，换热腔、风扇和换热器均采用了对称布局，即，在压床腔的两侧均设置了换热腔以及换热腔内的风扇和换热器，但是本公开的范围并不仅限于此。例如，换热腔、风扇和换热器也可以采用非对称布局，即，仅在压床腔的一侧设置换热腔以及换热腔内的风扇和换热器，例如，如图6所示。It should also be noted that in the structures of the heating systems shown in FIGS. 2 to 5 , the heat exchange chamber, the fan and the heat exchanger are all arranged symmetrically, that is, the heat exchange chamber and the fan and the heat exchanger in the heat exchange chamber are arranged on both sides of the press chamber, but the scope of the present disclosure is not limited to this. For example, the heat exchange chamber, the fan and the heat exchanger may also be arranged asymmetrically, that is, the heat exchange chamber and the fan and the heat exchanger in the heat exchange chamber are arranged only on one side of the press chamber, for example, as shown in FIG. 6 .

图6是示意性地示出根据本公开另一些实施例的用于化成机的加热系统的主视图。FIG. 6 is a front view schematically showing a heating system for a forming machine according to other embodiments of the present disclosure.

如图6所示，仅在压床腔311的一侧设置换热腔321。在换热腔321的内部设置有第一换热器210和第一风扇220。如图6所示，第一换热器210位于换热腔321的上部，第一风扇220位于换热腔321的下部。即，图6中的第一换热器210和第一风扇220的位置布置采用了与图2中的第一换热器210和第一风扇220的位置布置相同或相似的布置方式。As shown in FIG6 , a heat exchange chamber 321 is provided only on one side of the press chamber 311. A first heat exchanger 210 and a first fan 220 are provided inside the heat exchange chamber 321. As shown in FIG6 , the first heat exchanger 210 is located at the upper part of the heat exchange chamber 321, and the first fan 220 is located at the lower part of the heat exchange chamber 321. That is, the position arrangement of the first heat exchanger 210 and the first fan 220 in FIG6 adopts the same or similar arrangement as the position arrangement of the first heat exchanger 210 and the first fan 220 in FIG2 .

当然，本领域技术人员能够理解，图6中的第一换热器210和第一风扇220的位置布置也可以采用其他布置方式，例如图3至图5中的第一换热器210和第一风扇220的位置布置方式，因此，本公开的范围并不仅限于此。Of course, those skilled in the art will appreciate that the positional arrangement of the first heat exchanger 210 and the first fan 220 in FIG. 6 may also be arranged in other ways, such as the positional arrangement of the first heat exchanger 210 and the first fan 220 in FIGS. 3 to 5 , and therefore, the scope of the present disclosure is not limited thereto.

在上述实施例中，通过仅在压床腔的一侧设置换热腔，可以减少换热腔的数量，进而减少换热器和风扇的数量，从而节约成本。In the above embodiment, by arranging the heat exchange chamber only on one side of the press chamber, the number of heat exchange chambers can be reduced, thereby reducing the number of heat exchangers and fans, thereby saving costs.

图7是示出根据本公开另一些实施例的用于化成机的加热系统的结构示意图。FIG. 7 is a schematic structural diagram showing a heating system for a forming machine according to other embodiments of the present disclosure.

如图7所示，加热系统包括第一换热器210和第一风扇220，第一换热器210和第一风扇220设置在第一换热腔321或第二换热腔322中。As shown in FIG. 7 , the heating system includes a first heat exchanger 210 and a first fan 220 , and the first heat exchanger 210 and the first fan 220 are disposed in the first heat exchange cavity 321 or the second heat exchange cavity 322 .

如图7所示，加热系统还可以包括温度传感器230。温度传感器230设置在压床腔311中。温度传感器230用于检测压床腔内的温度。As shown in Fig. 7, the heating system may further include a temperature sensor 230. The temperature sensor 230 is disposed in the press chamber 311. The temperature sensor 230 is used to detect the temperature in the press chamber.

如图7所示，加热系统还可以包括控制器240。控制器240用于从温度传感器230接收压床腔311内的温度，并根据压床腔内的温度调节第一风扇220的转速。As shown in Fig. 7, the heating system may further include a controller 240. The controller 240 is used to receive the temperature in the press chamber 311 from the temperature sensor 230, and adjust the rotation speed of the first fan 220 according to the temperature in the press chamber.

这样，通过温度传感器检测压床腔内的当前温度，通过控制器基于压床腔内的当前温度调节风扇的转速，可以方便灵活地调节压床腔内的温度，从而方便进行化成工序。In this way, the current temperature in the press chamber is detected by the temperature sensor, and the speed of the fan is adjusted based on the current temperature in the press chamber by the controller. The temperature in the press chamber can be adjusted conveniently and flexibly, thereby facilitating the formation process.

例如，控制器240用于在压床腔内的温度大于温度阈值的情况下，控制减小风扇的转速，在压床腔内的温度小于温度阈值的情况下，控制增大风扇的转速，在压床腔内的温度等于温度阈值的情况下，控制风扇的转速不变。For example, the controller 240 is used to control the fan speed to decrease when the temperature in the press chamber is greater than the temperature threshold, control the fan speed to increase when the temperature in the press chamber is less than the temperature threshold, and control the fan speed to remain unchanged when the temperature in the press chamber is equal to the temperature threshold.

这里，该温度阈值可以根据实际需要来设置。例如，可以根据化成工序需要的温度来设置，因此，该温度阈值并不限于具体值，只要能满足化成工序的要求即可。Here, the temperature threshold can be set according to actual needs. For example, it can be set according to the temperature required by the formation process. Therefore, the temperature threshold is not limited to a specific value as long as it can meet the requirements of the formation process.

在上述实施例中，在压床腔内的温度大于温度阈值的情况下，控制减小风扇的转速，这样可以减小风量，从而方便压床腔降温；在压床腔内的温度小于温度阈值的情况下，控制增大风扇的转速，这样可以增大风量，从而方便压床腔升温；在压床腔内的温度等于温度阈值的情况下，控制风扇的转速不变，从而保持压床腔内的温度稳定。这样实现了通过控制风扇的转速来调节压床腔内的温度的目的，从而方便进行化成工序。In the above embodiment, when the temperature in the press chamber is greater than the temperature threshold, the fan speed is controlled to be reduced, so that the air volume can be reduced, thereby facilitating the cooling of the press chamber; when the temperature in the press chamber is less than the temperature threshold, the fan speed is controlled to be increased, so that the air volume can be increased, thereby facilitating the heating of the press chamber; when the temperature in the press chamber is equal to the temperature threshold, the fan speed is controlled to be unchanged, thereby maintaining the temperature in the press chamber stable. In this way, the purpose of adjusting the temperature in the press chamber by controlling the fan speed is achieved, thereby facilitating the formation process.

在一些实施例中，如图7所示，加热系统还可以包括阀门250。阀门250设置在第一换热器210的管路上。例如，阀门250可以设置在第一换热器210的第一支管路113上。又例如，阀门250可以设置在第一换热器210的第二支管路114上。例如，该阀门为电磁阀。In some embodiments, as shown in FIG7 , the heating system may further include a valve 250. The valve 250 is disposed on the pipeline of the first heat exchanger 210. For example, the valve 250 may be disposed on the first branch pipeline 113 of the first heat exchanger 210. For another example, the valve 250 may be disposed on the second branch pipeline 114 of the first heat exchanger 210. For example, the valve is a solenoid valve.

控制器240还可以用于根据压床腔内的温度调节阀门250的开度。这样通过控制器基于压床腔内的当前温度调节阀门的开度，可以方便灵活地调节压床腔内的温度，从而方便进行化成工序。The controller 240 can also be used to adjust the opening of the valve 250 according to the temperature in the press chamber. In this way, the controller can adjust the opening of the valve based on the current temperature in the press chamber, so that the temperature in the press chamber can be conveniently and flexibly adjusted, thereby facilitating the formation process.

例如，控制器240可以用于在压床腔内的温度大于温度阈值的情况下，控制减小阀门的开度，在压床腔内的温度小于温度阈值的情况下，控制增大阀门的开度，在压床腔内的温度等于温度阈值的情况下，控制阀门的开度不变。For example, the controller 240 can be used to control the valve opening to decrease when the temperature in the press chamber is greater than a temperature threshold, control the valve opening to increase when the temperature in the press chamber is less than the temperature threshold, and control the valve opening to remain unchanged when the temperature in the press chamber is equal to the temperature threshold.

在上述实施例中，在压床腔内的温度大于温度阈值的情况下，控制减小阀门的开度，这样可以减小换热器内的冷媒流量，从而方便压床腔降温；在压床腔内的温度小于温度阈值的情况下，控制增大阀门的开度，这样可以增大换热器内的冷媒流量，从而方便压床腔升温；在压床腔内的温度等于温度阈值的情况下，控制阀门的开度不变，从而保持压床腔内的温度稳定。这样实现了通过控制阀门的开度来调节压床腔内的温度的目的，从而方便进行化成工序。In the above embodiment, when the temperature in the press chamber is greater than the temperature threshold, the valve opening is controlled to be reduced, so that the refrigerant flow in the heat exchanger can be reduced, thereby facilitating the cooling of the press chamber; when the temperature in the press chamber is less than the temperature threshold, the valve opening is controlled to be increased, so that the refrigerant flow in the heat exchanger can be increased, thereby facilitating the heating of the press chamber; when the temperature in the press chamber is equal to the temperature threshold, the valve opening is controlled to remain unchanged, thereby maintaining the temperature in the press chamber stable. In this way, the purpose of adjusting the temperature in the press chamber by controlling the valve opening is achieved, thereby facilitating the formation process.

在一些实施例中，如图7所示，加热系统还可以包括报警装置260。报警装置260用于在接收到来自于控制器240的报警信号后进行报警。控制器240还可以用于在经过控制调节风扇的转速后的预定时间后，比较压床腔内的温度与温度阈值的大小，在压床腔内的温度与温度阈值不相等的情况下，发出报警信号。In some embodiments, as shown in FIG7 , the heating system may further include an alarm device 260. The alarm device 260 is used to give an alarm after receiving an alarm signal from the controller 240. The controller 240 may also be used to compare the temperature in the press chamber with a temperature threshold after a predetermined time after controlling and adjusting the speed of the fan, and to give an alarm signal when the temperature in the press chamber is not equal to the temperature threshold.

也就是说，在控制调节风扇的转速后的预定时间后，再次比较压床腔内的温度与温度阈值的大小，如果压床腔内的温度与温度阈值不相等，例如，压床腔内的温度依然大于或者小于温度阈值，则表明压床腔内的当前温度依然不适合化工工序的实施，则发出报警信号至报警装置，从而使得报警装置进行报警。通过报警处理，可以提醒工作人员当前的温度不适合进行化成工序，从而方便工作人员进行相应的处理。That is to say, after a predetermined time after the speed of the fan is controlled and adjusted, the temperature in the press chamber is compared with the temperature threshold again. If the temperature in the press chamber is not equal to the temperature threshold, for example, the temperature in the press chamber is still greater than or less than the temperature threshold, it indicates that the current temperature in the press chamber is still not suitable for the implementation of the chemical process, and an alarm signal is sent to the alarm device, so that the alarm device alarms. Through the alarm processing, the staff can be reminded that the current temperature is not suitable for the chemical process, so that the staff can carry out corresponding processing.

在本公开的一些实施例中，还提供了一种化成机，包括：如前所述的加热系统，例如，图1至图7所示的加热系统。In some embodiments of the present disclosure, a forming machine is further provided, comprising: a heating system as described above, for example, the heating system shown in FIGS. 1 to 7 .

图8是示出根据本公开一些实施例的化成机的分体结构的结构示意图。FIG. 8 is a schematic structural diagram showing the split structure of a forming machine according to some embodiments of the present disclosure.

如图8所示，该化成机的分体结构包括压床柜310，该压床柜310包括换热腔321。该分体结构还包括电源电控柜330和维修通道340。维修通道340位于压床柜310与电源电控柜330之间。可选地，该分体结构还包括侧面隔墙350，该侧面隔墙350位于压床柜310的至少一侧。例如，侧面隔墙350设置在压床柜310的后面，且沿着维修通道340设置。隔墙起到密封隔热的作用。例如，将多个如图8所示的分体结构叠加地放置在一起，即可组成化成机。As shown in Figure 8, the split structure of the forming machine includes a press cabinet 310, and the press cabinet 310 includes a heat exchange chamber 321. The split structure also includes a power supply and electric control cabinet 330 and a maintenance channel 340. The maintenance channel 340 is located between the press cabinet 310 and the power supply and electric control cabinet 330. Optionally, the split structure also includes a side partition wall 350, and the side partition wall 350 is located at least one side of the press cabinet 310. For example, the side partition wall 350 is arranged behind the press cabinet 310 and is arranged along the maintenance channel 340. The partition wall plays a role of sealing and heat insulation. For example, multiple split structures as shown in Figure 8 are placed together in a superimposed manner to form a forming machine.

在本公开的一些实施例中，还提供了一种化成系统，包括：多个如前所述的化成机。In some embodiments of the present disclosure, a formation system is further provided, comprising: a plurality of formation machines as described above.

图9是示出根据本公开一些实施例的化成系统的结构示意图。FIG. 9 is a schematic diagram showing the structure of a formation system according to some embodiments of the present disclosure.

例如，如图9所示，将多个化成机并排地设置在一起即可组成化成系统。即，化成机的分体可以在高度方向和水平方向进行组合成多层多列柜体，即化成系统。For example, as shown in Figure 9, a plurality of forming machines can be arranged side by side to form a forming system. That is, the split bodies of the forming machines can be combined in the height direction and the horizontal direction into a multi-layer multi-column cabinet, i.e., a forming system.

如图9所示，各个化成机300之间被侧面隔墙350隔开，使得各个化成机中相邻的化成机不直接连接。该化成系统还包括位于化成机顶部的顶部隔墙。该顶部隔墙起到密封的作用。As shown in Figure 9, each forming machine 300 is separated by a side partition wall 350 so that adjacent forming machines in each forming machine are not directly connected. The forming system also includes a top partition wall positioned at the top of the forming machine. The top partition wall plays a sealing effect.

图10是示出根据本公开另一些实施例的化成系统的结构示意图。FIG. 10 is a schematic diagram showing the structure of a formation system according to other embodiments of the present disclosure.

与图9所示的化成系统相比，图10所示的化成系统的区别在于：在图10所示的化成系统中，多个化成机300中相邻的化成机直接连接。通过使得相邻的化成机直接连接，而在相邻的化成机之间不设置侧面隔墙，从而可以减小设备的占地面积，提升空间利用率。Compared with the formation system shown in Figure 9, the difference of the formation system shown in Figure 10 is that: in the formation system shown in Figure 10, adjacent formation machines in a plurality of formation machines 300 are directly connected. By making adjacent formation machines directly connected, and not arranging side partition walls between adjacent formation machines, the floor space of the equipment can be reduced and the space utilization rate can be improved.

图11是示意性地示出根据本公开一些实施例的化成机的俯视图。图12是示意性地示出根据本公开一些实施例的化成机的侧面视图。图13是示意性地示出根据本公开一些实施例的化成机的正面视图。Figure 11 is a top view schematically showing a forming machine according to some embodiments of the present disclosure. Figure 12 is a side view schematically showing a forming machine according to some embodiments of the present disclosure. Figure 13 is a front view schematically showing a forming machine according to some embodiments of the present disclosure.

如图11至图13所示，在化成机（例如，化成机300a、300b和300c）的顶部设置有柔性隔墙360。该柔性隔墙360位于厂房吊顶365与化成机之间。即，该柔性隔墙作为顶部隔墙。As shown in Figures 11 to 13, a flexible partition wall 360 is provided on the top of the forming machine (for example, forming machines 300a, 300b and 300c). The flexible partition wall 360 is located between the plant ceiling 365 and the forming machine. That is, the flexible partition wall serves as a top partition wall.

图12中还示出了柔性隔墙360与厂房吊顶365的连接点355。另外，图12中的弯曲线表示隔墙360是柔性的。实际上，柔性隔墙360并不必须具有该弯曲线。Fig. 12 also shows the connection point 355 between the flexible partition wall 360 and the factory ceiling 365. In addition, the curved line in Fig. 12 indicates that the partition wall 360 is flexible. In fact, the flexible partition wall 360 does not necessarily have the curved line.

在相关技术中，厂房地面容易出现沉降的问题，这会导致厂房吊顶与化成机顶部之间的顶部隔墙的密封效果不佳。而在上述实施例中，通过采用柔性隔墙作为顶部隔墙，可以减小厂房地面的沉降造成厂房吊顶与化成机顶部之间的顶部隔墙的密封效果不佳的问题。In the related art, the factory floor is prone to settlement, which will lead to poor sealing effect of the top partition wall between the factory ceiling and the top of the forming machine. In the above embodiment, by using a flexible partition wall as the top partition wall, the problem of poor sealing effect of the top partition wall between the factory ceiling and the top of the forming machine caused by the settlement of the factory floor can be reduced.

图14是示意性地示出根据本公开另一些实施例的化成机的俯视图。FIG. 14 is a top view schematically showing a forming machine according to other embodiments of the present disclosure.

如图14所示，化成机包括压床柜310和电源电控柜330。该压床柜310包括压床腔311和换热腔。压床柜310设置在压床间315中，电源电控柜330设置在电源间335中。图14还示出了环境分隔界限345。压床间315内的温度小于压床柜的压床腔311内的温度，且电源间335内的温度小于压床腔311内的温度。电源间335内的湿度大于压床间315内的湿度，且电源间335内的湿度大于压床腔311内的湿度。As shown in FIG. 14 , the forming machine includes a press cabinet 310 and a power supply electric control cabinet 330. The press cabinet 310 includes a press chamber 311 and a heat exchange chamber. The press cabinet 310 is arranged in a press room 315, and the power supply electric control cabinet 330 is arranged in a power supply room 335. FIG. 14 also shows an environmental separation boundary 345. The temperature in the press room 315 is lower than the temperature in the press chamber 311 of the press cabinet, and the temperature in the power supply room 335 is lower than the temperature in the press chamber 311. The humidity in the power supply room 335 is higher than the humidity in the press room 315, and the humidity in the power supply room 335 is higher than the humidity in the press chamber 311.

在一些实施例中，压床腔内处于高温低湿的环境，压床间内处于常温低湿的环境，电源间内处于常温常湿的环境。例如，在压床腔311内，温度控制在45±5℃（即，温度范围为40℃至50℃），湿度控制在2%。例如，在压床间315内，温度控制在25±5℃（即，温度范围为20℃至30℃），湿度控制在2%。例如，在电源间335内，温度控制在25±5℃（即，温度范围为20℃至30℃），湿度控制在75%。In some embodiments, the press chamber is in a high temperature and low humidity environment, the press room is in a normal temperature and low humidity environment, and the power room is in a normal temperature and normal humidity environment. For example, in the press chamber 311, the temperature is controlled at 45±5°C (i.e., the temperature range is 40°C to 50°C), and the humidity is controlled at 2%. For example, in the press room 315, the temperature is controlled at 25±5°C (i.e., the temperature range is 20°C to 30°C), and the humidity is controlled at 2%. For example, in the power room 335, the temperature is controlled at 25±5°C (i.e., the temperature range is 20°C to 30°C), and the humidity is controlled at 75%.

在上述实施例中，通过三种环境的控制逐级地减小能源损耗。化成厂房不需要整体加热，可以将大幅减少能源损耗。In the above embodiment, energy loss is reduced step by step by controlling the three environments. The formation plant does not need to be heated as a whole, which can greatly reduce energy loss.

另外，在相关技术中，由于化成间需要人员进行日常维护，使得维护人员长时间处于高温作业状态下，进而使维护人员身体置身于中暑、热射病、昏迷等安全风险之中。In addition, in the related art, since the formation room needs personnel to perform daily maintenance, the maintenance personnel are in high-temperature working conditions for a long time, which puts the maintenance personnel at risk of heat stroke, heat stroke, coma, etc.

而本公开的实施例中，通过设置上述用于化成机的加热系统，可以对压床腔、压床间和电源间内的温度和湿度进行控制，使得工作人员在压床间和电源间内工作时不处于高温作业环境中，例如，维修通道可降低到常温，对维护人员的工作环境更友好。In the embodiments of the present disclosure, by providing the above-mentioned heating system for the chemical forming machine, the temperature and humidity in the press cavity, the press room and the power supply room can be controlled, so that the staff are not in a high-temperature working environment when working in the press room and the power supply room. For example, the maintenance passage can be lowered to normal temperature, which is more friendly to the working environment of the maintenance personnel.

图15是示意性地示出根据本公开一些实施例的化成系统的布局图。FIG. 15 is a diagram schematically showing a layout of a formation system according to some embodiments of the present disclosure.

如图15所示，该化成系统包括化成间510，该化成间510包括压床间315和电源间335。化成机300放置在该化成间510中。该化成系统还包括拆盘区520、组盘区530和高温浸润间540。高温浸润间540位于拆盘区520与组盘区530之间。该高温浸润间540还位于两个化成间510之间。这样设置化成系统的各个间室的位置，方便工作人员的维护和操作。As shown in Figure 15, this formation system comprises formation room 510, and this formation room 510 comprises press room 315 and power supply room 335.Forming machine 300 is placed in this formation room 510.This formation system also comprises dismantling plate area 520, assembly plate area 530 and high temperature soaking room 540.High temperature soaking room 540 is between dismantling plate area 520 and assembly plate area 530.This high temperature soaking room 540 is also between two formation rooms 510.The position of each compartment of formation system is set like this, convenient maintenance and operation of staff.

图16是示出根据本公开一些实施例的用于化成机的加热方法的流程图。化成机包括一个或多个压床柜，每个压床柜包括压床腔和在压床腔至少一侧的换热腔。如图16所示，该加热方法包括步骤S610至S620。FIG16 is a flow chart showing a heating method for a forming machine according to some embodiments of the present disclosure. The forming machine includes one or more press cabinets, each press cabinet including a press chamber and a heat exchange chamber on at least one side of the press chamber. As shown in FIG16 , the heating method includes steps S610 to S620.

在步骤S610，通过设置在换热腔中的换热器，利用来自于辅助设备的热量对换热腔内的空气加热。In step S610, the air in the heat exchange cavity is heated by using the heat from the auxiliary equipment through a heat exchanger disposed in the heat exchange cavity.

在步骤S620，通过设置在换热腔中的风扇，将加热后的空气输送至压床腔中。In step S620, the heated air is delivered to the press chamber by a fan disposed in the heat exchange chamber.

至此，提供了根据本公开一些实施例的用于化成机的加热方法。在该加热方法中，通过换热器，利用来自于辅助设备的热量对换热腔内的空气加热，并利用风扇将加热后的空气输送至压床腔中，这样方便在压床腔内进行化成工序，由于换热器是利用辅助设备的热量对空气进行加热的，即，利用废热能源加热化成设备，使电芯达到工艺温度，因此可以节省能源消耗。So far, a heating method for a formation machine according to some embodiments of the present disclosure is provided. In the heating method, the air in the heat exchange chamber is heated by heat from an auxiliary device through a heat exchanger, and the heated air is transported to the press chamber by a fan, so that the formation process is conveniently performed in the press chamber. Since the heat exchanger heats the air by heat from the auxiliary device, that is, the formation equipment is heated by waste heat energy, so that the battery cell reaches the process temperature, energy consumption can be saved.

在一些实施例中，加热方法还包括：通过温度传感器检测压床腔内的温度，并将压床腔内的温度传输到控制器；和通过控制器根据压床腔内的温度调节风扇的转速。这样，通过温度传感器检测压床腔内的当前温度，通过控制器基于压床腔内的当前温度调节风扇的转速，可以方便灵活地调节压床腔内的温度，从而方便进行化成工序。In some embodiments, the heating method further comprises: detecting the temperature in the press chamber by a temperature sensor and transmitting the temperature in the press chamber to a controller; and adjusting the speed of the fan by the controller according to the temperature in the press chamber. In this way, by detecting the current temperature in the press chamber by the temperature sensor and adjusting the speed of the fan by the controller based on the current temperature in the press chamber, the temperature in the press chamber can be conveniently and flexibly adjusted, thereby facilitating the formation process.

在一些实施例中，通过控制器根据压床腔内的温度调节风扇的转速，包括：在压床腔内的温度大于温度阈值的情况下，控制减小风扇的转速；在压床腔内的温度小于温度阈值的情况下，控制增大风扇的转速；和在压床腔内的温度等于温度阈值的情况下，控制风扇的转速不变。这样实现了通过控制风扇的转速来调节压床腔内的温度的目的，从而方便进行化成工序。In some embodiments, the controller adjusts the speed of the fan according to the temperature in the press chamber, including: when the temperature in the press chamber is greater than the temperature threshold, the fan speed is controlled to be reduced; when the temperature in the press chamber is less than the temperature threshold, the fan speed is controlled to be increased; and when the temperature in the press chamber is equal to the temperature threshold, the fan speed is controlled to remain unchanged. In this way, the purpose of adjusting the temperature in the press chamber by controlling the speed of the fan is achieved, thereby facilitating the chemical formation process.

在一些实施例中，加热方法还包括：通过控制器，根据压床腔内的温度调节设置在换热器的管路上的阀门的开度。这样通过控制器基于压床腔内的当前温度调节阀门的开度，可以方便灵活地调节压床腔内的温度，从而方便进行化成工序。In some embodiments, the heating method further comprises: adjusting the opening of a valve disposed on a pipeline of the heat exchanger according to the temperature in the press chamber by a controller. In this way, the temperature in the press chamber can be conveniently and flexibly adjusted by the controller based on the current temperature in the press chamber, thereby facilitating the formation process.

在一些实施例中，通过控制器，根据压床腔内的温度调节设置在换热器的管路上的阀门的开度，包括：在压床腔内的温度大于温度阈值的情况下，控制减小阀门的开度；在压床腔内的温度小于温度阈值的情况下，控制增大阀门的开度；和在压床腔内的温度等于温度阈值的情况下，控制阀门的开度不变。这样实现了通过控制阀门的开度来调节压床腔内的温度的目的，从而方便进行化成工序。In some embodiments, the controller adjusts the opening of the valve disposed on the pipeline of the heat exchanger according to the temperature in the press chamber, including: when the temperature in the press chamber is greater than the temperature threshold, the valve opening is controlled to be reduced; when the temperature in the press chamber is less than the temperature threshold, the valve opening is controlled to be increased; and when the temperature in the press chamber is equal to the temperature threshold, the valve opening is controlled to remain unchanged. In this way, the purpose of adjusting the temperature in the press chamber by controlling the valve opening is achieved, thereby facilitating the formation process.

在一些实施例中，加热方法还包括：通过控制器，在经过控制调节风扇的转速后的预定时间后，比较压床腔内的温度与温度阈值的大小，在压床腔内的温度与温度阈值不相等的情况下，向报警装置发出报警信号以使得报警装置进行报警。通过报警处理，可以提醒工作人员当前的温度不适合进行化成工序，从而方便工作人员进行相应的处理。In some embodiments, the heating method further includes: comparing the temperature in the press chamber with the temperature threshold through the controller after a predetermined time after the speed of the fan is controlled and adjusted, and sending an alarm signal to the alarm device when the temperature in the press chamber is not equal to the temperature threshold so that the alarm device alarms. Through the alarm processing, the staff can be reminded that the current temperature is not suitable for the chemical formation process, so as to facilitate the staff to carry out corresponding processing.

Here, the temperature in the warehouse is the temperature in the press chamber. This step is to determine the relationship between the temperature in the press chamber and the temperature threshold. When the temperature in the warehouse is greater than the temperature threshold, the process proceeds to step S705; when the temperature in the warehouse is less than the temperature threshold, the process proceeds to step S708; when the temperature in the warehouse is equal to the temperature threshold, the process proceeds to step S711.

在步骤S707，超温报警。即，报警当前温度过高。In step S707, an over-temperature alarm is issued, that is, an alarm is issued that the current temperature is too high.

在步骤S710，低温报警。即，报警当前温度过低。In step S710, a low temperature alarm is issued, that is, an alarm is issued that the current temperature is too low.

在步骤S711，保持热水阀门不变，保持风扇转速不变。In step S711, the hot water valve is kept unchanged, and the fan speed is kept unchanged.

在步骤S712，化成流程启动。In step S712, the formation process starts.

在步骤S713，化成流程结束。In step S713, the formation process ends.

在步骤S714，关闭风扇，关闭热水阀门。In step S714, the fan is turned off and the hot water valve is closed.

在步骤S716，托盘移出库位。即，托盘从压床腔移出。In step S716, the pallet is moved out of the storage location, that is, the pallet is moved out of the press cavity.

至此，提供了根据本公开另一些实施例的用于化成机的加热方法。在该方法中，厂房热泵产生的废弃热能引入到化成设备，通过换热器将化成机压床柜升温到工艺温度，从而使电芯达到工艺温度，因此可以节省能源消耗。Thus, a heating method for a formation machine according to other embodiments of the present disclosure is provided. In this method, waste heat generated by a heat pump in a plant is introduced into the formation equipment, and the temperature of the formation machine press cabinet is raised to the process temperature through a heat exchanger, so that the battery cell reaches the process temperature, thereby saving energy consumption.
