[0024] The frame 1 has a roller conveyor 2 on its top and a conveyor belt 3 on its outside. A carrier plate 4 is provided on the outside of the conveyor belt 3 and a connecting rod 5 is connected to the outside of the carrier plate 4. A pressure plate 6 is connected to the outer end of the connecting rod 5. An upper swing rod 7 and a lower swing rod 8 are provided in the middle of the frame 1. The upper swing rod 7 is located above the lower swing rod 8. The right sides of the upper swing rod 7 and the lower swing rod 8 are connected by a first spring 11. A connecting plate 9 is connected to the left end of both the upper swing rod 7 and the lower swing rod 8. A cutting blade 10 is connected to the inner side of the connecting plate 9.

[0025] A film holder 12 is located on top of the frame 1. A material roller 13 is located on the top of the film holder 12. A movable roller 14 is located on the right side of the material roller 13. A second spring 15 is connected to the rear end of the movable roller 14. A connecting frame 16 is located on the left side of the material roller 13. A pressure roller 17 is located below the connecting frame 16. The pressure roller 17 is flexibly connected to the connecting frame 16 through a third spring 18.

[0026] like Figure 1 , Figure 2 and Figure 3Conveyor belts 3 are symmetrically arranged on the front and rear sides of the middle roller conveyor 2, and carrier plates 4 are equally spaced on the outer side of the conveyor belts 3 to facilitate the installation of the carrier plates 4. Connecting rods 5 are symmetrically arranged on the front and rear sides of the carrier plates 4, and the connecting rods 5 are integrated with the pressure plate 6 to facilitate the pressure plate 6 to squeeze the upper swing rod 7 and the lower swing rod 8. The upper swing rod 7 and the lower swing rod 8 are symmetrically arranged about the front and rear of the roller conveyor 2, and the middle of the upper swing rod 7 and the lower swing rod 8 are rotatably connected to the frame 1 to facilitate the upper swing rod 7 and the lower swing rod 8 to drive the cutting knife 10 to work.

[0027] like Figure 1 , Figure 2 and Figure 4 The inner part of the film frame 12 is provided with a sliding groove, and the movable roller 14 forms a sliding structure with the film frame 12 through its sliding groove, which makes it convenient for the movable roller 14 to clamp the protective film. The pressure roller 17 is arranged on the left and right sides corresponding to the material roller 13, and the pressure roller 17 is attached to the carrier plate 4, which facilitates the adhesion of the protective film to the touch screen.

[0028] Working principle: When using this screen protector application device in touchscreen production, such as Figure 4 As shown, by pushing the movable roller 14, the movable roller 14 slides in the groove in the film holder 12, placing the protective film roll on the material roller 13, and releasing the movable roller 14, the movable roller 14 clamps the protective film roll under the action of the second spring 15, placing the touch screen in the groove of the carrier plate 4, and by pulling the protective film, the protective film is attached to the touch screen, and at the same time, the touch screen with the film attached is located below the pressure roller 17, and the pressure roller 17 adheres the protective film to the touch screen through the elastic action of the third spring 18;

[0029] By starting roller conveyor 2, such as Figure 1 As shown, the roller conveyor 2 drives the conveyor belt 3 to rotate, thereby driving the carrier plate 4 to move. During the movement of the carrier plate 4, the touch screen moves synchronously, and under the pressure of the pressure roller 17, the protective film is pulled and moved synchronously, thereby continuously completing the film application.

[0030] When the carrier plate 4 moves to the upper swing arm 7 and the lower swing arm 8, as Figure 1 As shown, the connecting rod 5 on the carrier plate 4 presses the inner sides of the upper swing rod 7 and the lower swing rod 8 through the pressure plate 6, causing the middle parts of the upper swing rod 7 and the lower swing rod 8 to rotate around the frame 1. This causes the left ends of the upper swing rod 7 and the lower swing rod 8 to drive the connecting plate 9 to move closer to each other, and the protective film is cut by the cutting blade 10, thereby breaking the protective film between adjacent touch screens, which facilitates the separate storage of the touch screens. This is the entire working process of the film-applying device for touch screen production.
