Description
技术领域Technical Field
本发明涉及光伏电池技术领域，具体涉及光伏组件冷弯设备及光伏组件冷弯方法。The invention relates to the technical field of photovoltaic cells, and in particular to photovoltaic component cold bending equipment and a photovoltaic component cold bending method.
背景技术Background Art
曲面光伏组件在汽车和建筑幕墙等特殊场景具有重要应用，具备光伏发电的特点。曲面光伏组件一般具有双层玻璃曲面。Curved photovoltaic modules have important applications in special scenarios such as automobiles and building curtain walls, and have the characteristics of photovoltaic power generation. Curved photovoltaic modules generally have a double-layer glass surface.
目前，实现玻璃弯曲的方法一般分为热弯和冷弯。其中，热弯工艺需要在玻璃融化点附近（约600℃至700℃）实现玻璃弯曲。由于曲面光伏组件的薄膜电池沉积在玻璃基板上，与玻璃基板一体，因此热弯过程中薄膜电池同样承受高温。然而高温容易破坏薄膜材料和电池性能，且先将玻璃基板热弯再在弯曲的玻璃基板上制备大面积薄膜电池的难度较大。At present, the methods of achieving glass bending are generally divided into hot bending and cold bending. Among them, the hot bending process requires the glass to be bent near the melting point of the glass (about 600℃ to 700℃). Since the thin-film cells of the curved photovoltaic modules are deposited on the glass substrate and integrated with the glass substrate, the thin-film cells are also subjected to high temperatures during the hot bending process. However, high temperatures can easily destroy the thin-film materials and battery performance, and it is difficult to first hot-bend the glass substrate and then prepare large-area thin-film cells on the curved glass substrate.
冷弯工艺则是在常温或低温下进行弯曲作业，能够避免高温的破坏作用。现有的冷弯设备一般依靠工装夹具将光伏组件的下表面压合到模具的上表面，并通过长时间的固定形成曲面。一方面，采用工装夹具和模具的使用成本较高，且工作效率较低。另一方面，由于冷弯的本质是控制玻璃弹性形变，曲面光伏组件从模具上拆除后，外力消失，容易导致曲面光伏组件的曲面回弹。The cold bending process is to perform bending operations at room temperature or low temperature, which can avoid the destructive effects of high temperature. Existing cold bending equipment generally relies on fixtures to press the lower surface of the photovoltaic module to the upper surface of the mold, and forms a curved surface through long-term fixation. On the one hand, the use cost of fixtures and molds is high, and the work efficiency is low. On the other hand, since the essence of cold bending is to control the elastic deformation of glass, after the curved photovoltaic module is removed from the mold, the external force disappears, which easily causes the curved surface of the curved photovoltaic module to rebound.
发明内容Summary of the invention
有鉴于此，本发明提供了一种光伏组件冷弯设备及光伏组件冷弯方法，以解决现有的冷弯设备采用工装夹具和模具实现弯折，存在使用成本较高，工作效率较低且容易出现曲面回弹的问题。In view of this, the present invention provides a photovoltaic module cold bending device and a photovoltaic module cold bending method to solve the problems that the existing cold bending equipment uses tooling fixtures and molds to achieve bending, has high cost, low work efficiency and is prone to surface rebound.

为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
下面结合图1至图2，描述本发明的实施例。The following describes an embodiment of the present invention in conjunction with FIG. 1 and FIG. 2 .
根据本发明的实施例，一方面，如图1所示，提供了一种光伏组件冷弯设备，主要包括：底座1、多个支撑柱2和多个伸缩机构。多个支撑柱2间隔且可移动地设于底座1上，支撑柱2的上端设有固定部201，多个固定部201适于按照预设排布分别与单玻薄膜电芯基板3的一面固定连接。多个伸缩机构与多个支撑柱2一一对应，伸缩机构用于带动支撑柱2相对底座1按照预设方式上下移动，以使单玻薄膜电芯基板3弯曲至预设形状。According to an embodiment of the present invention, on the one hand, as shown in FIG1 , a photovoltaic module cold bending device is provided, which mainly includes: a base 1, a plurality of support columns 2 and a plurality of telescopic mechanisms. The plurality of support columns 2 are arranged on the base 1 at intervals and movably, and a fixing portion 201 is provided at the upper end of the support column 2, and the plurality of fixing portions 201 are suitable for being fixedly connected to one side of a single-glass thin-film battery substrate 3 according to a preset arrangement. The plurality of telescopic mechanisms correspond one to one with the plurality of support columns 2, and the telescopic mechanisms are used to drive the support columns 2 to move up and down relative to the base 1 in a preset manner, so that the single-glass thin-film battery substrate 3 is bent to a preset shape.
本发明实施例提供的光伏组件冷弯设备，将单玻薄膜电芯基板3的一面与多个支撑柱2的固定部201连接，另一面露出。利用多个伸缩机构分别带动多个支撑柱2，支撑柱2再带动单玻薄膜电芯基板3弯折至预设形状，能够省略工装夹具和模具，节约使用成本并提高工作效率。The photovoltaic module cold bending equipment provided by the embodiment of the present invention connects one side of the single-glass thin-film battery substrate 3 to the fixing portion 201 of multiple support columns 2, and the other side is exposed. Multiple support columns 2 are driven by multiple telescopic mechanisms respectively, and the support columns 2 then drive the single-glass thin-film battery substrate 3 to bend to a preset shape, which can omit tooling fixtures and molds, save use costs and improve work efficiency.
相对于传统的冷弯方式需要同时涉及单玻薄膜电芯基板3的双面加工，本发明实施例仅需将单玻薄膜电芯基板3的一面与多个支撑柱2的固定部201连接，另一面露出，能够在另一面继续敷设封装层5以及弯折后的玻璃基板6，从而完成曲面光伏组件的制备。Compared with the traditional cold bending method which requires double-sided processing of the single-glass thin-film battery cell substrate 3, the embodiment of the present invention only requires connecting one side of the single-glass thin-film battery cell substrate 3 to the fixing portion 201 of multiple support columns 2, leaving the other side exposed, and the encapsulation layer 5 and the bent glass substrate 6 can be further applied on the other side, thereby completing the preparation of the curved photovoltaic module.
由于单玻薄膜电芯基板3仅一面与多个支撑柱2连接，单玻薄膜电芯基板3弯折后，多个支撑柱2能够继续固定单玻薄膜电芯基板3，并维持单玻薄膜电芯基板3始终处于弯折状态。也即单玻薄膜电芯基板3的另一面能够在固定部201与单玻薄膜电芯基板3保持连接的情况下，继续敷设封装层5以及弯折后的玻璃基板6，从而完成曲面光伏组件的制备，进而克服曲面回弹问题。Since only one side of the single-glass thin-film battery substrate 3 is connected to the multiple support pillars 2, after the single-glass thin-film battery substrate 3 is bent, the multiple support pillars 2 can continue to fix the single-glass thin-film battery substrate 3 and keep the single-glass thin-film battery substrate 3 in a bent state. That is, the other side of the single-glass thin-film battery substrate 3 can continue to lay the encapsulation layer 5 and the bent glass substrate 6 while the fixing part 201 remains connected to the single-glass thin-film battery substrate 3, thereby completing the preparation of the curved photovoltaic module and overcoming the curved surface rebound problem.
具体地，多个支撑柱2的数量以及排布需要根据单玻薄膜电芯基板3的尺寸和曲面形状要求适配设置。单玻薄膜电芯基板3的尺寸和曲面形状确定后，支撑柱2的数量以及排布随之确定，并且支撑柱2固定在底座1上。为了便于支撑柱2的移动，支撑柱2可以为圆柱。Specifically, the number and arrangement of the plurality of support columns 2 need to be adapted and set according to the size and curved surface shape requirements of the single-glass thin-film battery substrate 3. After the size and curved surface shape of the single-glass thin-film battery substrate 3 are determined, the number and arrangement of the support columns 2 are determined accordingly, and the support columns 2 are fixed on the base 1. In order to facilitate the movement of the support columns 2, the support columns 2 can be cylindrical.
需要说明的是，本发明实施例不对伸缩机构的结构进行限制，可以根据需要选择现有的任意结构。例如，伸缩机构为电机驱动齿轮的伸缩机构。通过电机带动皮带轮传动，进而带动齿轮转动，齿轮与齿轮啮合后传递到支撑柱2上，最终带动支撑柱2进行伸缩运动，能够实现精确控制。It should be noted that the embodiment of the present invention does not limit the structure of the telescopic mechanism, and any existing structure can be selected as needed. For example, the telescopic mechanism is a telescopic mechanism in which a motor drives a gear. The motor drives the pulley to rotate, and then the gears are meshed with each other to transmit to the support column 2, and finally the support column 2 is driven to perform telescopic movement, which can achieve precise control.
在一个实施例中，如图1所示，支撑柱2沿轴向设有通孔，支撑柱2的下端设有与通孔连通的接口4，接口4与抽真空设备连接，固定部201与通孔连通并设有缓冲件，固定部201通过缓冲件以及通孔与单玻薄膜电芯基板3形成负压连接。In one embodiment, as shown in FIG. 1 , a through hole is provided in the axial direction of the support column 2, an interface 4 connected to the through hole is provided at the lower end of the support column 2, the interface 4 is connected to the vacuum pumping equipment, the fixing part 201 is connected to the through hole and is provided with a buffer, and the fixing part 201 forms a negative pressure connection with the single-glass thin-film battery cell substrate 3 through the buffer and the through hole.
支撑柱2内部设有连接抽真空设备的通孔，以通过抽真空形成负压的方式实现固定部201与单玻薄膜电芯基板3的固定连接，连接稳定，且方便拆卸。另外，固定部201设有缓冲件，能够防止固定部201与单玻薄膜电芯基板3硬接触，从而利于保护单玻薄膜电芯基板3。The support column 2 is provided with a through hole for connecting a vacuum device, so that the fixing part 201 and the single-glass thin-film battery substrate 3 are fixedly connected by vacuuming to form a negative pressure, and the connection is stable and easy to disassemble. In addition, the fixing part 201 is provided with a buffer to prevent the fixing part 201 from hard contact with the single-glass thin-film battery substrate 3, thereby protecting the single-glass thin-film battery substrate 3.
需要说明的是，本发明实施例也不对抽真空设备的结构进行限制，可以根据需要选择现有的任意结构。例如，抽真空设备可以为真空泵。It should be noted that the embodiment of the present invention does not limit the structure of the vacuum pumping device, and any existing structure can be selected as needed. For example, the vacuum pumping device can be a vacuum pump.
进一步地，在一个实施例中，缓冲件为吸盘或垫圈，结构简单，使用成本较低。Furthermore, in one embodiment, the buffer is a suction cup or a gasket, which has a simple structure and low use cost.
在一个实施例中，接口4通过软管与抽真空设备连接。支撑柱2需要上下移动，接口4通过软管与抽真空设备连接能够提供移动过程中的缓冲，避免接口4与抽真空设备连接处因支撑柱2的移动而断开。In one embodiment, the interface 4 is connected to the vacuum device through a hose. The support column 2 needs to move up and down, and the interface 4 is connected to the vacuum device through a hose to provide a buffer during the movement, thereby preventing the connection between the interface 4 and the vacuum device from being disconnected due to the movement of the support column 2.
在一个实施例中，支撑柱2为实心结构，固定部201通过固定胶与单玻薄膜电芯基板3的一面固定粘接。固定胶可以采用高温有机或无机强力胶。支撑柱2为实心结构能够提高支撑柱2的连接强度，固定部201通过固定胶与单玻薄膜电芯基板3的一面固定粘接，能够进一步降低使用成本，且连接较为紧固。In one embodiment, the support column 2 is a solid structure, and the fixing portion 201 is fixedly bonded to one side of the single-glass thin-film battery substrate 3 by a fixing glue. The fixing glue can be a high-temperature organic or inorganic strong glue. The support column 2 is a solid structure, which can improve the connection strength of the support column 2. The fixing portion 201 is fixedly bonded to one side of the single-glass thin-film battery substrate 3 by a fixing glue, which can further reduce the use cost and the connection is relatively tight.
单玻薄膜电芯基板3弯折后，需要敷设封装层5以及弯折后的玻璃基板6，从而完成曲面光伏组件的制备。曲面光伏组件制备完成后，可以通过外力直接将单玻薄膜电芯基板3与固定部201脱离，或者采用对应溶剂将固定胶溶解后，再将单玻薄膜电芯基板3与固定部201脱离。After the single-glass thin-film battery substrate 3 is bent, it is necessary to lay the encapsulation layer 5 and the bent glass substrate 6 to complete the preparation of the curved photovoltaic module. After the curved photovoltaic module is prepared, the single-glass thin-film battery substrate 3 can be directly separated from the fixing part 201 by external force, or the fixing glue can be dissolved by a corresponding solvent, and then the single-glass thin-film battery substrate 3 can be separated from the fixing part 201.
在一个实施例中，光伏组件冷弯设备100还包括多个移动机构，多个移动机构分别与多个支撑柱2一一对应，各个支撑柱2分别通过移动机构设于底座1上，移动机构用于带动支撑柱2相对底座1沿水平方向移动。In one embodiment, the photovoltaic module cold bending equipment 100 also includes multiple moving mechanisms, which correspond to multiple support columns 2 one by one. Each support column 2 is arranged on the base 1 through the moving mechanism, and the moving mechanism is used to drive the support column 2 to move horizontally relative to the base 1.
通过多个移动机构分别带动多个支撑柱2相对底座1沿水平方向移动，能够适应不同规格单玻薄膜电芯基板3的弯折需求，从而提高光伏组件冷弯设备100的应用范围，使用灵活。By using multiple moving mechanisms to drive multiple support columns 2 to move horizontally relative to the base 1, the bending requirements of single-glass thin-film battery substrates 3 of different specifications can be met, thereby improving the application range of the photovoltaic module cold bending equipment 100 and making it flexible to use.
需要说明的是，本发明实施例也不对移动机构的结构进行限制，可以根据需要选择现有的任意结构。例如，在底座1上设置滑动轨道，支撑柱2上设有滚轮，通过滚轮在滑动轨道上滑动以调整支撑柱2的水平分布。It should be noted that the embodiment of the present invention does not limit the structure of the moving mechanism, and any existing structure can be selected as needed. For example, a sliding track is provided on the base 1, and a roller is provided on the support column 2, and the horizontal distribution of the support column 2 is adjusted by sliding the roller on the sliding track.
为实现光伏组件冷弯设备的基本功能，本实施例中的光伏组件冷弯设备还可以包括其他必需的模块或部件，例如控制器、紧固件等。需要说明的是，光伏组件冷弯设备所包括的其他必需的模块或部件，可以选用任意合适的现有构造。为清楚简要地说明本实施例所提供的技术方案，在此将不再对上述部分进行赘述，说明书附图也进行了相应简化。但应该理解，本发明的实施例在范围上并不因此而受到限制。In order to realize the basic functions of the photovoltaic module cold bending device, the photovoltaic module cold bending device in this embodiment may also include other necessary modules or components, such as a controller, fasteners, etc. It should be noted that the other necessary modules or components included in the photovoltaic module cold bending device can be selected from any suitable existing structures. In order to clearly and briefly explain the technical solution provided by this embodiment, the above part will not be repeated here, and the drawings in the specification are also simplified accordingly. However, it should be understood that the scope of the embodiments of the present invention is not limited by this.
根据本发明的实施例，另一方面，如图2所示，还提供了一种光伏组件冷弯方法，采用上述的光伏组件冷弯设备100，包括以下步骤：According to an embodiment of the present invention, on the other hand, as shown in FIG. 2 , a photovoltaic module cold bending method is also provided, using the photovoltaic module cold bending device 100 described above, comprising the following steps:
S100：根据单玻薄膜电芯基板3的尺寸和曲面形状要求，选择支撑柱2的数量，并在底座1上排布支撑柱2。此步骤可以通过计算软件预先模拟和设计。S100: According to the size and curved surface shape requirements of the single-glass thin-film battery substrate 3, the number of support pillars 2 is selected, and the support pillars 2 are arranged on the base 1. This step can be simulated and designed in advance by computing software.
S200：将各个支撑柱2的固定部201分别与单玻薄膜电芯基板3的一面固定连接。S200 : The fixing portion 201 of each support column 2 is fixedly connected to one side of the single-glass thin-film battery substrate 3 .
S300：利用伸缩机构带动固定部201按照预设方式上下伸缩，以使单玻薄膜电芯基板3弯曲至预设形状。S300: Using the telescopic mechanism to drive the fixing part 201 to telescope up and down in a preset manner, so that the single-glass thin-film battery cell substrate 3 is bent into a preset shape.
本发明实施例提供的光伏组件冷弯方法，提前根据单玻薄膜电芯基板3的尺寸和曲面形状要求，确定支撑柱2的数量，并排布多个支撑柱2，之后将单玻薄膜电芯基板3的一面与多个支撑柱2的固定部201连接，另一面露出。利用多个伸缩机构分别带动多个支撑柱2，支撑柱2再带动单玻薄膜电芯基板3弯折至预设形状，能够省略工装夹具和模具，节约使用成本并提高工作效率。由于单玻薄膜电芯基板3仅一面与多个支撑柱2连接，单玻薄膜电芯基板3弯折后，多个支撑柱2能够继续固定单玻薄膜电芯基板3，并维持单玻薄膜电芯基板3始终处于弯折状态。单玻薄膜电芯基板3的另一面能够在固定部201与单玻薄膜电芯基板3保持连接的情况下，继续敷设封装层5以及弯折后的玻璃基板6，从而完成曲面光伏组件的制备，进而克服曲面回弹问题。The cold bending method of photovoltaic modules provided by the embodiment of the present invention determines the number of support columns 2 in advance according to the size and curved surface shape requirements of the single-glass thin-film battery substrate 3, and arranges multiple support columns 2, and then connects one side of the single-glass thin-film battery substrate 3 to the fixing part 201 of the multiple support columns 2, and the other side is exposed. Multiple support columns 2 are driven by multiple telescopic mechanisms respectively, and the support columns 2 then drive the single-glass thin-film battery substrate 3 to bend to a preset shape, which can omit tooling fixtures and molds, save use costs and improve work efficiency. Since only one side of the single-glass thin-film battery substrate 3 is connected to multiple support columns 2, after the single-glass thin-film battery substrate 3 is bent, the multiple support columns 2 can continue to fix the single-glass thin-film battery substrate 3 and maintain the single-glass thin-film battery substrate 3 in a bent state. The other side of the single-glass thin-film battery substrate 3 can continue to lay the encapsulation layer 5 and the bent glass substrate 6 while the fixing part 201 remains connected to the single-glass thin-film battery substrate 3, thereby completing the preparation of the curved photovoltaic module, thereby overcoming the curved surface rebound problem.
具体地，步骤S100、S200以及S300均在图2中的B段进行，也即冷弯段。Specifically, steps S100, S200 and S300 are all performed in section B in FIG. 2 , ie, the cold bending section.
在一个实施例中，伸缩机构带动多个支撑柱2逐步上升，以使单玻薄膜电芯基板3弯曲至预设形状。相对于采用下降的方式，能够避免单玻薄膜电芯基板3内部的功能层被破坏，并避免单玻薄膜电芯基板3的表面薄膜破损或脱落。In one embodiment, the telescopic mechanism drives the plurality of support columns 2 to gradually rise, so that the single-glass thin-film battery substrate 3 is bent to a preset shape. Compared with the descending method, the functional layer inside the single-glass thin-film battery substrate 3 can be prevented from being damaged, and the surface film of the single-glass thin-film battery substrate 3 can be prevented from being damaged or falling off.
需要说明的是，伸缩机构带动多个支撑柱2逐步上升的具体形式需要根据实际需要计算得出。示例性地，如图1所示，支撑柱2设置五个，伸缩机构先带动最外侧的两个支撑柱2向上移动，再带动相邻内侧的两个支撑柱2向上移动，最后同时带动上述四个支撑柱2同时向上移动，以使单玻薄膜电芯基板3弯折至预设形状。It should be noted that the specific form of the telescopic mechanism driving the multiple support columns 2 to gradually rise needs to be calculated according to actual needs. For example, as shown in FIG1 , five support columns 2 are provided, and the telescopic mechanism first drives the two outermost support columns 2 to move upward, then drives the two adjacent inner support columns 2 to move upward, and finally drives the above four support columns 2 to move upward at the same time, so that the single-glass thin-film battery substrate 3 is bent to a preset shape.
在一个实施例中，光伏组件冷弯方法还包括：In one embodiment, the photovoltaic module cold bending method further comprises:
S400：弯折单玻薄膜电芯基板3前和/或弯折单玻薄膜电芯基板3的过程，对单玻薄膜电芯基板3进行加热，加热温度为150℃至450℃，加热时间为0.5 h至12 h。对单玻薄膜电芯基板3弯折前和/或弯折过程中加热，实现退火去应力处理，利于玻璃弯曲成型以及消除玻璃弯曲产生的应力和降低玻璃回弹，并且加热温度在150℃至450℃，对薄膜电池的影响较小。加热源可以采用灯管或加热丝等常规加热源。S400: Before bending the single-glass thin-film battery substrate 3 and/or during bending the single-glass thin-film battery substrate 3, the single-glass thin-film battery substrate 3 is heated, and the heating temperature is 150°C to 450°C, and the heating time is 0.5 h to 12 h. The single-glass thin-film battery substrate 3 is heated before bending and/or during bending to achieve annealing and stress relief treatment, which is beneficial to glass bending and forming, and eliminates the stress generated by glass bending and reduces glass rebound. The heating temperature is 150°C to 450°C, which has little effect on the thin-film battery. The heating source can be a conventional heating source such as a lamp tube or a heating wire.
如图2中的A段所示，弯折单玻薄膜电芯基板3前，对单玻薄膜电芯基板3进行加热，加热温度为150℃至450℃，属于进片段。加热完成后将未弯折的单玻薄膜电芯基板3通过传送机构传送至光伏组件冷弯设备100上方，进行冷弯处理。As shown in section A of FIG. 2 , before bending the single-glass thin-film battery substrate 3, the single-glass thin-film battery substrate 3 is heated at a temperature of 150° C. to 450° C., which belongs to the in-section. After the heating is completed, the unbent single-glass thin-film battery substrate 3 is conveyed to the top of the photovoltaic module cold bending device 100 through a conveying mechanism for cold bending treatment.
如图2中的B段所示，弯折曲面光伏组件的过程也可以对单玻薄膜电芯基板3加热。As shown in section B of FIG. 2 , the process of bending the curved photovoltaic module can also heat the single-glass thin-film battery cell substrate 3 .
相对于传统的对封装完成后的曲面光伏组件进行加热的方式，其受封装材料的限制，封装材料一般为EVA（乙烯-醋酸乙烯酯共聚物）或PVB（聚乙烯醇缩丁醛），加热温度不能超过140℃。本发明实施例在单玻薄膜电芯基板3弯折前、弯折过程中进行加热，无需考虑封装材料，且加热温度在150℃至450℃，加热温度更高，有利于玻璃基板6弯曲和降低回弹。Compared with the traditional method of heating the curved photovoltaic module after encapsulation, it is limited by the encapsulation material, which is generally EVA (ethylene-vinyl acetate copolymer) or PVB (polyvinyl butyral), and the heating temperature cannot exceed 140°C. In the embodiment of the present invention, the single-glass thin-film battery substrate 3 is heated before and during the bending process, without considering the encapsulation material, and the heating temperature is between 150°C and 450°C. The higher the heating temperature, the more conducive it is to the bending of the glass substrate 6 and reduce the rebound.
在一个实施例中，光伏组件冷弯方法还包括：In one embodiment, the photovoltaic module cold bending method further comprises:
S500：弯折单玻薄膜电芯基板3至预设形状后，依次将封装层5以及弯折后的玻璃基板6敷设于单玻薄膜电芯基板3上，形成曲面光伏组件。也即，曲面光伏组件由单玻薄膜电芯基板3、封装层5和玻璃基板6组装后形成。封装层5可以采用EVA或PVB等常规封装材料。S500: After bending the single-glass thin-film battery substrate 3 to a preset shape, the encapsulation layer 5 and the bent glass substrate 6 are sequentially applied on the single-glass thin-film battery substrate 3 to form a curved photovoltaic module. That is, the curved photovoltaic module is formed by assembling the single-glass thin-film battery substrate 3, the encapsulation layer 5 and the glass substrate 6. The encapsulation layer 5 can be made of conventional encapsulation materials such as EVA or PVB.
单玻薄膜电芯基板3弯折后随光伏组件冷弯设备100一起进入敷设段，如图2中的C段所示。玻璃基板6的弯折可以采用热弯形式。弯折后的玻璃基板6的形状需要与弯折后的单玻薄膜电芯基板3一致。After being bent, the single-glass thin-film battery cell substrate 3 enters the laying section together with the photovoltaic module cold bending equipment 100, as shown in section C in FIG2 . The bending of the glass substrate 6 can be performed by hot bending. The shape of the bent glass substrate 6 needs to be consistent with the single-glass thin-film battery cell substrate 3 after being bent.
S600：对曲面光伏组件加热预封装，以使封装层5固定粘合玻璃基板6和单玻薄膜电芯基板3。此处加热温度为100℃至140℃，加热时间为1 min至30 min。同时，还可以对玻璃基板6施加压力，以促进粘合，还能够排出曲面光伏组件内部的气泡，也即单玻薄膜电芯基板3与封装层5之间的气泡以及封装层5与玻璃基板6之间的气泡。S600: Pre-encapsulate the curved photovoltaic module by heating so that the encapsulation layer 5 is fixedly bonded to the glass substrate 6 and the single-glass thin-film battery substrate 3. The heating temperature here is 100°C to 140°C, and the heating time is 1 min to 30 min. At the same time, pressure can also be applied to the glass substrate 6 to promote adhesion and to discharge bubbles inside the curved photovoltaic module, that is, bubbles between the single-glass thin-film battery substrate 3 and the encapsulation layer 5 and bubbles between the encapsulation layer 5 and the glass substrate 6.
如图2中的D段所示，此部分为加热预封装段，通过封装层5受热部分熔融和交联，将玻璃基板6和单玻薄膜电芯基板3初步粘接固定。As shown in section D in FIG. 2 , this section is a heated pre-packaging section, in which the glass substrate 6 and the single-glass thin-film battery cell substrate 3 are initially bonded and fixed by partially melting and cross-linking the packaging layer 5 when heated.
S700：曲面光伏组件加热预封装完成后，将固定部201与曲面光伏组件分离，之后通过传送机构将曲面光伏组件传送至封装设备处进行第二次封装处理，形成最终的双玻曲面薄膜光伏组件。如图2中的E段所示，也即封装段。封装设备可以采用真空袋和高压釜等常规封装设备。S700: After the curved photovoltaic module is heated and pre-packaged, the fixing part 201 is separated from the curved photovoltaic module, and then the curved photovoltaic module is transported to the packaging equipment through the conveying mechanism for a second packaging process to form the final double-glass curved thin-film photovoltaic module. As shown in section E in FIG2 , this is the packaging section. The packaging equipment can be conventional packaging equipment such as vacuum bags and autoclaves.
由于单玻薄膜电芯基板3仅一面与多个支撑柱2连接，另一面能够继续敷设封装层5以及弯折后的玻璃基板6，从而完成曲面光伏组件的制备，利于批量化流水线生产，提高生产效率，进而利于推广。弯折后的玻璃基板6能够进一步维持单玻薄膜电芯基板3冷弯后的形状，进一步减小曲面回弹。Since only one side of the single-glass thin-film battery substrate 3 is connected to the multiple support columns 2, the other side can continue to lay the encapsulation layer 5 and the bent glass substrate 6, thereby completing the preparation of the curved photovoltaic module, which is conducive to mass production, improves production efficiency, and is further conducive to promotion. The bent glass substrate 6 can further maintain the shape of the single-glass thin-film battery substrate 3 after cold bending, and further reduce the springback of the curved surface.
在其他的一些实施例中，单玻薄膜电芯基板3弯折后还可以在单玻薄膜电芯基板3的上表面，即未与固定部201连接的一面涂覆粘接材料，例如玻璃胶。之后将弯折后的单玻薄膜电芯基板3以及光伏组件冷弯设备100转移至待安装区域，例如汽车或建筑框架上，通过粘接材料将单玻薄膜电芯基板3与待安装区域固定后，再拆卸光伏组件冷弯设备100。In some other embodiments, after the single-glass thin-film battery substrate 3 is bent, an adhesive material, such as glass glue, may be applied to the upper surface of the single-glass thin-film battery substrate 3, that is, the side not connected to the fixing portion 201. Then, the bent single-glass thin-film battery substrate 3 and the photovoltaic module cold bending device 100 are transferred to the area to be installed, such as a car or a building frame, and the single-glass thin-film battery substrate 3 is fixed to the area to be installed by the adhesive material, and then the photovoltaic module cold bending device 100 is disassembled.
虽然结合附图描述了本发明的实施例，但是本领域技术人员可以在不脱离本发明的精神和范围的情况下做出各种修改和变型，这样的修改和变型均落入由所附权利要求所限定的范围之内。Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
