本发明涉及注塑与天线相结合技术领域，具体涉及一种后盖与天线集成件及其制造方法。The invention relates to the technical field of combining injection molding and antennas, in particular to a rear cover and antenna integration and a manufacturing method thereof.
背景技术Background technique
随着5G时代的到来，智能手机等智能终端中的天线数量越来越多。以往FPC天线都是粘贴在后盖的内表面，随着天线数量的增多，为了增加天线净空间，天线工程师需要将多个FPC天线粘贴在后盖的外表面，这里所谓的后盖是指智能终端的外观件，这种后盖一方面起到结构支撑和承载天线的功能，另一方面还起到美化智能终端外观面的作用，即需要通过表面处理来遮蔽后盖外表面上的FPC天线图案，并达到满意的外观效果。With the advent of the 5G era, the number of antennas in smart terminals such as smartphones is increasing. In the past, FPC antennas were pasted on the inner surface of the back cover. With the increase in the number of antennas, in order to increase the net space of the antenna, antenna engineers need to paste multiple FPC antennas on the outer surface of the back cover. The so-called back cover here refers to the smart The exterior part of the terminal, this kind of back cover plays the role of structural support and carrying the antenna on the one hand, and also plays the role of beautifying the appearance of the smart terminal on the other hand, that is, the FPC antenna on the outer surface of the back cover needs to be covered by surface treatment pattern, and achieve a satisfactory appearance.
另外，LDS和LAP技术都能够将多个天线镭雕、化镀在塑胶后盖的外表面。但是，LDS技术需要采用专用的改性塑胶原料注塑成型后盖，改性塑胶原料一方面价格高，另一方面质地脆，因此，改性塑胶原料注塑成型的后盖机械强度差。专利201410146680.8给出的LAP技术是一种LDS升级技术，LAP技术可采用普通塑胶原料注塑成型后盖，然后经激光粗化、化学活化，再经特殊的化学镀在塑胶后盖上形成三维电路图，用来充当天线。LAP技术甚至可在玻璃、陶瓷等其它非金属后盖上镭雕、化镀天线。In addition, both LDS and LAP technologies can laser engrave and chemically plate multiple antennas on the outer surface of the plastic back cover. However, the LDS technology needs to use special modified plastic raw materials for injection molding of the back cover. On the one hand, the modified plastic raw materials are expensive, and on the other hand, the texture is brittle. Therefore, the mechanical strength of the back cover molded by modified plastic raw materials is poor. The LAP technology given in the patent 201410146680.8 is an LDS upgrade technology. The LAP technology can use ordinary plastic raw materials to form the back cover, then undergo laser roughening, chemical activation, and then special chemical plating on the plastic back cover to form a three-dimensional circuit diagram. Used as an antenna. LAP technology can even engrave and electroplate antennas on glass, ceramics and other non-metal back covers.
为了美化智能终端的外观面，在后盖外观面上镭雕、化镀LAP天线或LDS天线后，同样需要通过表面处理来遮蔽后盖外表面上的天线图案。LAP天线或LDS天线的材质是金属材料，其表面特性与后盖非金属材料的表面特性不同，对天线图案进行遮蔽，需要进行喷涂、固化、打磨反复多次的表面处理，才能达到满意的外观效果，其中打磨工序还有可能将天线磨断。可见，在后盖外表面镭雕、化镀LAP天线或LDS天线并进行遮蔽，若要达到满意的外观效果，不仅制造工艺周期长，而且良品直通率低，造成制造成本较高。In order to beautify the appearance of the smart terminal, it is also necessary to cover the antenna pattern on the outer surface of the back cover through surface treatment after laser engraving or electroless plating of LAP antennas or LDS antennas on the outer surface of the back cover. The material of the LAP antenna or LDS antenna is a metal material, and its surface characteristics are different from those of the non-metallic material of the back cover. To cover the antenna pattern, it needs repeated surface treatment of spraying, curing, and polishing to achieve a satisfactory appearance. As a result, the grinding process may also break the antenna. It can be seen that laser engraving, electroless plating LAP antenna or LDS antenna on the outer surface of the back cover and shielding, to achieve a satisfactory appearance, not only the manufacturing process cycle is long, but also the pass-through rate of good products is low, resulting in high manufacturing costs.
综上所述，天线工程师需要将多个天线制作在智能终端后盖的外表面，然而，如何采用常规表面处理技术来遮蔽天线图案，并达到满意的外观效果，这在技术上还是个难题。To sum up, antenna engineers need to fabricate multiple antennas on the outer surface of the rear cover of the smart terminal. However, how to use conventional surface treatment technology to cover the antenna pattern and achieve a satisfactory appearance is still a technical problem.

本发明一种后盖与LAP天线集成件2的制造方法，具体包括以下步骤：A method for manufacturing the rear cover and the LAP antenna assembly 2 of the present invention specifically comprises the following steps:
步骤一：通过模具一次注塑成型，得到后盖5，但其厚度比后盖与LAP天线集成件2的厚度薄；Step 1: The rear cover 5 is obtained by one-time injection molding of the mold, but its thickness is thinner than the thickness of the rear cover and the LAP antenna integrated part 2;
步骤二：在步骤一所得到的后盖5的外表面上镭雕、化镀LAP天线201的主体，在步骤一所得到的后盖5的内表面上镭雕、化镀LAP天线201的馈电点和接地点；Step 2: On the outer surface of the back cover 5 obtained in step 1, the main body of the LAP antenna 201 is laser-engraved and chemically plated; Electrical and grounding points;
步骤三：通过模内注塑，在含有LAP天线201的后盖5上形成较薄的塑胶包裹层4；Step 3: Form a thinner plastic wrapping layer 4 on the back cover 5 containing the LAP antenna 201 through in-mold injection molding;
步骤四：对模内注塑后的后盖与LAP天线复合体进行常规表面处理便得到后盖与LAP天线集成件2。Step 4: Perform conventional surface treatment on the in-molded back cover and LAP antenna complex to obtain the back cover and LAP antenna integrated part 2 .
其中，常规表面处理是指喷涂处理或NCVM或两者的组合处理。Among them, conventional surface treatment refers to spraying treatment or NCVM or a combination of both.
相对于现有技术，本发明的有益效果是：Compared with the prior art, the beneficial effects of the present invention are:
1、通过模内注塑工艺，将LAP天线包裹在后盖与塑胶包裹层之间，得到的后盖与LAP天线复合体外表面具有相同的表面特性，对其进行常规表面处理，就能达到满意的外观效果，表面处理成本大幅下降；1. Through the in-mold injection molding process, the LAP antenna is wrapped between the back cover and the plastic wrapping layer. The obtained back cover has the same surface characteristics as the outer surface of the LAP antenna complex. A satisfactory surface treatment can be achieved by conventional surface treatment. Appearance effect, the cost of surface treatment is greatly reduced;
2、由于是在塑胶包裹层上进行表面处理，表面处理不会直接接触到LAP天线，因而LAP天线不会被磨断，提高了LAP天线的良品率；2. Since the surface treatment is carried out on the plastic wrapping layer, the surface treatment will not directly contact the LAP antenna, so the LAP antenna will not be broken, which improves the yield rate of the LAP antenna;
3、由于能够在后盖的外表面制作多个三维LAP天线，天线净空间更大，因而天线设计的灵活度更高，可增加天线数量，提高天线性能。3. Since multiple three-dimensional LAP antennas can be fabricated on the outer surface of the back cover, the net space of the antenna is larger, so the flexibility of the antenna design is higher, the number of antennas can be increased, and the performance of the antenna can be improved.
以上是对本发明的较佳实施例进行了具体说明，但本发明并不限于所述实施例，熟悉本领域的技术人员在不违背本发明精神的前提下还可做作出种种的等同变形或替换，如玻璃后盖与LAP天线集成件、陶瓷后盖与LAP天线集成件，这些等同的变形或替换均包含在本申请权利要求所限定的范围内。The above is a specific description of the preferred embodiments of the present invention, but the present invention is not limited to the described embodiments, and those skilled in the art can also make various equivalent deformations or replacements without violating the spirit of the present invention. , such as glass back cover and LAP antenna integration, ceramic back cover and LAP antenna integration, these equivalent deformations or replacements are included in the scope of the claims of the present application.
