[0027] The following is combined with Figure 1-5 This application is described in further detail.

[0028] Reference Figure 1 and Figure 4 A plastic lens film stripping machine comprises a machine body 1 and a positioning frame 6. A liquid discharge pipe 2 is connected to one side of the bottom of the machine body 1. A butterfly valve is arranged on the liquid discharge pipe 2 to prevent the film stripping liquid from being discharged during the film stripping process. Slide rails 3 are fixedly connected to both sides of the inner wall of the machine body 1. A limit block is arranged at the bottom of the slide rail 3 to prevent the bottom of the positioning frame 6 from contacting the bottom of the inner wall of the machine body 1. Cover plates 4 are arranged on both sides of the top of the machine body 1. A rotating mechanism 5 is arranged between the bottom of the two sets of cover plates 4 and the machine body 1. The rotating mechanism 5 is a 90° limit hinge to prevent the two sides from contacting each other. The cover plate 4 is perpendicular to the top surface of the body 1, which is convenient for drying the lenses on the positioning frame 6. Both sides of the positioning frame 6 are fixedly connected with sliders 7 adapted to the slide rails 3, and the top of the positioning frame 6 is fixedly connected with a handle 8. The inner side of the positioning frame 6 is also fixedly connected with multiple groups of positioning plates 18. The positioning plates 18 and the positioning frame 6 are both provided with positioning grooves 19. The material of the positioning plates 18 is corrosion-resistant rubber. The distance between the two groups of positioning plates 18 is less than the height of the plastic lenses. Multiple groups of plastic lenses can be positioned separately to avoid mutual interference when the film is faded.

[0029] Reference Figure 1 and Figure 2 An air pump 9 is fixedly connected to both sides of the outer wall of the body 1, and two groups of air pipes 10 are connected to the air pump 9. One end of the two groups of air pipes 10 is connected to an air outlet hopper 11, and the air outlet hopper 11 is fixed on the cover plate 4. A screen 12 is provided at the air inlet end of the air pump 9. An air flow is generated by the air pump 9, and air is blown through the air outlet hopper 11 to quickly dry the plastic lens on the positioning frame 6.

[0030] Reference Figure 2 and Figure 3 The bottom of both sides of the inner wall of the body 1 are fixedly connected with return springs 13, and a movable frame 14 is fixedly connected between the two groups of return springs 13, so that the movable frame 14 can shake, and then drive the positioning frame 6 to shake. A driving box 15 is fixedly connected to one side of the inner wall of the body 1 and below the return spring 13. The top of the movable frame 14 is fixedly connected with multiple groups of driving plates 16, and the multiple groups of driving plates 16 are respectively arranged at the bottom of both sides of the positioning frame 6, so that when the movable frame 14 moves horizontally, the driving plates 16 can make the bottom of the positioning frame 6 shake, thereby increasing the film-fading effect of the plastic lens, and the bottom of the movable frame 14 is fixedly connected with a contact plate 17.

[0031] Reference Figure 5A vertical rod 20 is fixedly connected between the two sides of the inner wall of the driving box 15, and a driving motor is fixedly connected to one side of the vertical rod 20. A cam 21 is fixedly connected to the output shaft of the driving motor. A concave plate 22 is slidably connected between the two sides of the inner wall of the driving box 15. Two sets of restoring springs 23 are fixedly connected to one side of the concave plate 22. A driving rod 24 is fixedly connected to one side of the concave plate 22 and between the two sets of restoring springs 23. One end of the driving rod 24 abuts against the contact plate 17. The driving motor continuously drives the cam 21 to rotate, and then when the protruding part of the cam 21 presses against the concave plate 22, the concave plate 22 can be pushed outward. Then, when the protruding part of the cam 21 is away from the concave plate 22, the concave plate 22 is reset under the action of the restoring spring 23, so that the driving rod 24 can reciprocate in the horizontal direction, driving the movable frame 14 to reciprocate. One end of the two sets of restoring springs 23 is fixedly connected to the inner wall of the driving box 15, and the cam 21 is adapted to the concave plate 22.

[0032] The implementation principle of this embodiment is as follows: when in use, a proper amount of film stripping liquid is placed inside the body 1, and then the plastic lenses are placed on the positioning frames 6 in turn, and then the positioning grooves 19 provided at the upper and lower ends can be used to position the plastic lenses. After a proper amount of plastic lenses are placed on the three positioning frames 6, the three positioning frames 6 are inserted into the body 1 in turn, so that the slider 7 is located inside the slide rail 3, and the bottom of the positioning frame 6 is located between the two sets of driving plates 16, and then the cover plate 4 is closed, so that the plastic lenses can be film stripped under the action of the film stripping liquid, and then the driving motor is started, and the cam 21 is driven to rotate by the output shaft of the driving motor, and when the protruding portion of the cam 21 presses against the concave plate 22, the concave plate 22 can be pushed outward, and then the protruding portion of the cam 21 is far away from the concave plate 22. When leaving the concave plate 22, the concave plate 22 is reset under the action of the restoring spring 23. Under the continuous action of the driving motor and the restoring spring 23, the driving rod 24 continuously strikes the contact plate 17, which can make the movable frame 14 shake, and the bottom of the positioning frame 6 shakes through the driving plate 16, thereby realizing dynamic film stripping and increasing the efficiency of film stripping. Then, the film stripping liquid used can be discharged through the drain pipe 2. After the film stripping is completed, the cover plate 4 is opened so that the cover plate 4 stands on the body 1, and then the air pump 9 is started to generate air flow and discharge from the air outlet hopper 11, and then the positioning frame 6 is taken out of the body 1 through the handle 8 in turn, so that the positioning frame 6 can be timely stopped at a position where the output gas of the air outlet hopper 11 can be blown, thereby increasing the drying effect of the plastic lens and facilitating subsequent processing.
