[0028] The cutting component 4 is used for automatically cutting the protective film;

[0029] Furthermore, the cutting assembly 4 is composed of a moving frame 8, a moving block 9, a cutter 10, a connecting frame 11 and a driving screw 12. The moving frame 8 is located inside the connecting frame body 1 and close to one end of the bonding roller 2. The moving block 9 is slidably connected to the inside of the moving frame 8. The cutter 10 is rotatably connected to the outside of the moving block 9. The connecting frame 11 is located outside the moving frame 8 and inside the connecting frame body 1. The driving screw 12 is rotatably connected to the inside of the connecting frame 11. When the lens is coated, the protective film can be automatically cut by the cutting assembly 4, and there is no need for manual cutting with scissors, thereby increasing the efficiency of lens protective film coating.

[0030] Among them, a guide groove 13 is opened at one end of the movable frame 8 close to the cutter 10, and the internal structure size of the guide groove 13 is designed to correspond to the external structure size of the cutter 10. The cutter 10 is connected to the movable frame 8 through the guide groove 13, and the cutter 10 is slidably connected to the guide groove 13. When the cutter 10 is displaced, it can be guided by the guide groove 13 to prevent the cutter 10 from being offset, which affects the effect of cutting the protective film.

[0031] Secondly, the end of the moving frame 8 away from the moving block 9 is rotatably connected to the threaded barrel 14, and a threaded groove 15 is provided inside the threaded barrel 14. The internal structure size of the threaded groove 15 is designed to correspond to the external structure size of the driving screw 12. The driving screw 12 extends to the inside of the connecting frame body 1 and is fixedly connected to the driving end of the driving motor. A first telescopic cylinder is provided inside the moving frame 8 and on the outside of the moving block 9. The driving end of the first telescopic cylinder is fixedly connected to the moving block 9, and the threaded groove 15 is threadedly connected to the driving screw 12, so that the threaded barrel 14 can be threadedly connected to the driving screw 12. The driving motor is started, and the threaded barrel 14 is driven to move through the threaded groove 15, so that the moving frame 8 can move, and the cutter 10 is driven to move laterally. The first telescopic cylinder is started to drive the moving block 9 to move, so that the cutter 10 can move longitudinally, contact the protective film, and cut the protective film.

[0032] Furthermore, the interior of the connecting frame 11 is rotatably connected to a guide rod 16, and a connecting groove is provided at one end of the moving frame 8 close to the threaded tube 14. The internal structure size of the connecting groove is designed to correspond to the external structure size of the guide rod 16.

[0033] The limiting component 7 is used to limit the protective film placed outside the shaft 5;

[0034] Furthermore, the limit assembly 7 is composed of a limit block 17, a rotating rod 18, a spiral groove 19, a guide block 20, a limit gear 21, a clamping block 22, a fixed seat 23 and a compression spring 24. The limit block 17 is slidably connected to the outside of the placement shaft 5, the rotating rod 18 is rotationally connected to the inside of the placement shaft 5, the spiral groove 19 is opened on the outside of the rotating rod 18, and the two groups of guide blocks 20 are both located inside the limit block 17 and inside the placement shaft 5. The limit gear 21 is fixedly connected to the outside of the rotating rod 18 and located on the outside of the placement shaft 5. The clamping block 22 is located on the outside of the limit gear 21. The fixed seat 23 is located on the outside of the clamping block 22 and fixedly connected to the outside of the connecting frame body 1. The compression spring 24 is located inside the fixed seat 23 and on the outside of the clamping block 22. When the protective film roll is placed on the outside of the placement shaft 5, it can be limited by the limit assembly 7 to prevent the protective film roll from being offset, which affects the effect of the lens coating.

[0035] Furthermore, the placement shaft 5 and the connecting seat 6 are rotatably connected, the external structure size of the guide block 20 is designed to correspond to the internal structure size of the spiral groove 19, the limit block 17 is connected to the spiral groove 19 through the guide block 20, and a fixed block 25 is provided at the end of the placement shaft 5 away from the limit gear 21. When the protective film roll is placed on the outside of the placement shaft 5, the connection between the clamping block 22 and the limit gear 21 is disconnected, so that the limit gear 21 can be rotated, thereby allowing the rotating rod 18 to rotate. Rotating the rotating rod 18 allows the spiral groove 19 on its outside to rotate, driving the two groups of guide blocks 20 inside it to move, thereby allowing the limit block 17 to move, and cooperating with the fixed block 25 to limit the protective film roll. When the protective film roll rotates, it can be prevented from being offset, which affects the effect of the lens coating.

[0036] In this embodiment, the implementation scenario is specifically as follows: in actual use, when the protective film roll is placed on the outside of the placement shaft 5, the connection between the clamping block 22 and the limiting gear 21 is disconnected, so that the limiting gear 21 can rotate, thereby enabling the rotating rod 18 to rotate, and rotating the rotating rod 18 allows the spiral groove 19 on its outside to rotate, driving the two groups of guide blocks 20 inside it to move, thereby enabling the limiting block 17 to move, and cooperating with the fixed block 25 to limit the protective film roll. When the protective film roll rotates, it can prevent it from deviating, which will affect the lens coating effect. The lens is contacted with the two groups of bonding rollers 2 so that the lens can contact the protective film, and the bonding roller 2 drives the lens to move so that the protective film can be bonded to the surface of the lens. , start the driving motor, drive the threaded barrel 14 to move through the threaded groove 15, so that the moving frame 8 can be moved, drive the cutter 10 to move horizontally, start the second telescopic cylinder, drive the guide rod 16 to rotate, so that the moving frame 8 can rotate, drive the cutter 10 to move vertically, so that the cutter 10 can move to the outside of the protective film, start the first telescopic cylinder, drive the moving block 9 to move, so that the cutter 10 can move longitudinally, contact the protective film, and cut the protective film. When the protective film can be automatically cut by the cutting component 4, there is no need to manually hold scissors for cutting, thereby increasing the efficiency of the lens protective film coating. Compared with the existing composite device, the utility model can improve the overall practicality of the composite device through design.
