Technical Field
[0001] The utility model relates to the technical field of automatic edge trimming devices, and specifically relates to an automatic edge trimming device for the edge of an OCA module. Background Art
[0002] An OCA module usually refers to various optoelectronic devices or components bonded with OCA optical transparent adhesive. Attaching an OCA release film to the OCA module and cutting its edge neatly is convenient for subsequent applications and processing. This process is particularly important in the assembly of electronic products, especially in the manufacturing of touch screens, displays, and other optical components.
[0003] However, in actual use, when cutting the OCA release film, usually only one side of the module is pressed, and pressure cannot be applied to both sides of the cutting part simultaneously, resulting in damage such as deformation and rupture of the OCA release film. For this reason, we propose an automatic edge trimming device for the edge of an OCA module, which can apply pressure to both sides of the cutting position for uniform support and compression.

Two rotating rollers are rotatably disposed inside the fixed frame, and a belt is sleeved on the outer sides of the two rotating rollers. A first sliding groove is formed on one side of the sliding bracket, and a first motor is slidably disposed inside the first sliding groove. The output end of the first motor is connected to one of the rotating rollers.
