It can effectively buffer the impact, prevent the touch screen from bursting, or prevent the glass panel from breaking and scattering due to accidental impact of the mobile phone, reduce the hidden damage of the glass panel, and ensure the safety of users; it can also maintain the unique gloss and texture of tempered glass and improve the surface hardness. For the film-attaching process under the touch screen, the protective film is attached under the touch screen. The protective film consists of an upper release paper layer and a lower adhesive layer. The adhesive layer is pre-attached to the base film, and then the release paper layer is torn off and attached to the bottom of the touch screen. Finally, it is cut on the base film to achieve attachment.

At this time, start the electric telescopic rod 16. When the electric telescopic rod 16 is started, it directly drives the sealing plug 17 to open the small diameter pipe in the control tube 14. Since the air pressure in the negative pressure box 12 is lower than the air pressure in the wind hood 9, the air in the wind hood 9 is introduced into the negative pressure box 12. When the air pressure in the wind hood 9 drops, the external atmospheric pressure can press the film-sticking equipment onto the film-sticking table 8. After the film-sticking equipment is pressed, the control tube 14 is closed to ensure the air tightness of the wind hood 9. When film sticking, the hydraulic cylinder 3 drives the lifting plate 7 to press down to stick the film.
