[0030] See also Figure 1-Figure 5 , the utility model provides the following technical solutions:

[0031] A light guide plate packaging and processing device, comprising:

[0032] Move plate 1;

[0033] The film sticking assembly includes a limit slide bar 2, a film sticking plate 3, a spring groove 4, a spring plate 5 and a telescopic spring 6. The limit slide bar 2, the spring groove 4, the spring plate 5 and the telescopic spring 6 are provided with two, the two limit slide bars 2 are fixedly connected to the lower end of the movable plate 1, the film sticking plate 3 is slidably connected to the circumferential surface of the two limit slide bars 2, the two spring grooves 4 are respectively opened on the circumferential surfaces of the two film sticking plates 3, the two spring plates 5 are fixedly connected to the upper end of the film sticking plate 3 and slide in the two spring grooves 4 respectively, and the two telescopic springs 6 are respectively fixedly connected to the upper inner walls of the two spring grooves 4 and the upper ends of the two spring plates 5;

[0034] The pressure assembly includes a torque groove 7, a rotation groove 8, a rotation rod 9, a torque spring 10 and a pressure plate 11. The torque groove 7, the rotation groove 8, the rotation rod 9 and the torque spring 10 are provided with two. The pressure plate 11 is rotatably connected to the side inner wall of the film-sticking plate 3. The two torque grooves 7 are respectively opened at the two side ends of the pressure plate 11. The two rotation grooves 8 are respectively opened at one side inner wall of the two torque grooves 7. The two rotation rods 9 are respectively fixedly connected to the two side inner walls of the film-sticking plate 3 and rotate in the two rotation grooves 8 respectively. The two torque springs 10 are respectively fixedly connected to the one side inner wall of the two torque grooves 7 and the two side inner walls of the film-sticking plate 3;

[0035] The film sticking arm 14 is fixedly connected to the lower end of the moving plate 1;

Figure 2 The driving assembly is connected to the driving rod 22 to drive the driving rod 22 to move along the "return" groove as a track. The circular sliding block 21 is connected to the moving plate 1 through the vertical moving rod 25. The device is arranged on the conveyor belt of the light guide plate. When the driving rod 22 moves to the leftmost end of the groove, it moves downward, contacts the light guide plate and performs film pasting through the film pasting assembly. After that, the moving plate 1 moves to the right. After the film pasting is completed, the moving plate 1 moves upward until the moving plate 1 turns back to the leftmost end to paste the film on the next light guide plate.

The circular sliding block 21 is fixedly connected to the circumferential surface of the driving rod 22, and the lower end of the limiting inner plate 17 is fixedly connected to two bases 16.

[0047] In this embodiment: the driving motor 18 is used to drive the driving rod 22 to move to apply film to the light guide plate. The driving rod 22 is a strip-shaped groove. The circular sliding block 21 is fixed to the driving rod 22 and is limited by the driving rod 22 to slide in the driving rod 22. The driving motor 18 drives the driving rotating rod 19 to rotate.
