Description
技术领域technical field
本实用新型涉及背光组装机的背光片撕模技术领域，具体涉及一种背光组装机的撕膜滚轮。The utility model relates to the technical field of backlight film tearing molds of a backlight assembly machine, in particular to a film tearing roller of a backlight assembly machine.
背景技术Background technique
手机中的背光片(背光模组)是非常重要的组件，功能在于供应充足的亮度与分布均匀的光源，使手机能正常显示影像；背光片使用时需要与液晶显示屏之间进行组装，在背光片组装之前，表面要贴合一层贴膜防止背光片被污染划伤，而贴合过程又需要将贴膜撕掉才能使用；目前市面上多采用背光组装机来实现撕膜操作，比如申请号为201410378280.x的专利申请文件中就介绍了一种组装机，包括背光片取料平台(又称定位平台)、背光片组装平台；背光片组装平台，用于背光片完成撕膜及后续的组装工作。还设置了一个X轴模组(横向动作模组)设置了一个执行机构，该执行机构用于将背光片从取料平台上，移送到背光片组装平台，并在移送后的往复过程中，完成背光片表面贴膜的撕除工作。具体的撕膜部件为一个圆柱形滚轮，滚轮的外周包覆一层PU胶层，撕膜时执行机构将滚轮下压与背光片表面贴膜接触，然后从背光片的一端开始滚动至另一端，且整个滚轮还进行平移运动实现撕膜；但是，目前行业内使用较多的滚轮其规格一般为滚轮包覆PU胶层后的直径设定为30mm；滚轮硬度为50邵氏硬度；这样规格的滚轮带来一个问题，由于直接比较大，而且外周包覆的PU胶层的直径也随之很大，在与背光片压合过程，由于PU胶层柔软，且直径大必然增加了滚轮与背光片表面贴膜的接触面积，这就造成了二者之间的粘附力过大而导致整个背光片一起被撕起，使得背光片被磕碰、划伤，从而导致产品报废。The backlight film (backlight module) in the mobile phone is a very important component. Its function is to supply sufficient brightness and evenly distributed light source, so that the mobile phone can display images normally; when the backlight film is used, it needs to be assembled with the LCD screen. Before the backlight is assembled, a layer of film should be pasted on the surface to prevent the backlight from being polluted and scratched, and the film needs to be torn off before it can be used during the lamination process. At present, backlight assembly machines are often used on the market to realize the film tearing operation, such as the application number In the patent application documents for 201410378280.x, an assembly machine was introduced, including a backlight sheet picking platform (also known as a positioning platform), a backlight sheet assembly platform; a backlight sheet assembly platform, used for backlight sheet tearing and subsequent Assembly work. An X-axis module (horizontal action module) is also provided with an actuator, which is used to transfer the backlight sheet from the retrieving platform to the backlight sheet assembly platform, and in the reciprocating process after the transfer, Complete the tearing off of the surface film of the backlight sheet. The specific film tearing part is a cylindrical roller, and the outer periphery of the roller is covered with a layer of PU adhesive layer. When tearing the film, the actuator presses the roller down to contact the surface film of the backlight, and then rolls from one end of the backlight to the other end. And the entire roller also performs a translational movement to tear the film; however, the specifications of the rollers used more in the industry are generally set to 30mm in diameter after the roller is coated with the PU adhesive layer; the hardness of the roller is 50 Shore hardness; such specifications The roller brings a problem. Because the direct ratio is relatively large, and the diameter of the PU adhesive layer coated on the outer periphery is also large, in the process of pressing the backlight film, because the PU adhesive layer is soft and the diameter is large, the roller and the backlight will inevitably increase. The contact area of the film on the surface of the film will cause excessive adhesion between the two and cause the entire backlight film to be torn off together, causing the backlight film to be bumped and scratched, resulting in product scrapping.
