The rotation output pulley 733 is connected to the rotation input pulley 734 via a timing belt, and the rotation motor 732 drives the rotation plate 741 to rotate around the rotation input gear 734 via a pulley transmission.
After the double-sided film tearing mechanism 5 tears the protective film on the surface of the light guide plate, the protective film which is torn off can be wound on the first adhesive wheel set 513 and the second adhesive wheel set 523, and if the protective film is not cleaned in time, the film tearing work of a lower light guide plate can be influenced. Therefore, after the double-sided film tearing mechanism 5 finishes film tearing, the first clamping motor 712 and the second clamping motor 722 of the clamping mechanism 7 are respectively started to move the clamping mechanism bracket 731 to the side of the first adhesive wheel set 513 and the second adhesive wheel set 523. The rotary motor 732 is activated so that the two pneumatic jaws 742 on the rotating plate 741 correspond to the first viscous wheel set 513 and the second viscous wheel set 523, respectively.
