AI Technical Summary

Technical Problem

Existing screen protector applicators are prone to problems such as inaccurate application, dust ingress, and air bubbles when applying screen protectors to tempered glass. Furthermore, the electronic device is prone to shifting in the positioning slot, affecting the application effect.

Method used

An automatic exhaust dust-free film application box was designed. The first and second springs are vertically set to fix the electronic equipment. Combined with the positioning column and cover structure, it ensures that the equipment does not shift during the film application process and maintains accurate positioning through the elasticity of the springs. The dust-free film application is achieved by covering with the cover and cooperating with the traction belt.

Benefits of technology

It improves the accuracy and effectiveness of film application, prevents equipment misalignment, ensures a dust-free application process, and simplifies the operation procedure.

Abstract

The automatic exhaust dust-free film pasting box comprises a film pasting device body and a film pasting assembly, a containing groove is formed in the film pasting device body, a first elastic piece and a second elastic piece are arranged on the inner side of the containing groove, one end of the film pasting device body is connected with a cover body in a rotating mode, and the other end of the film pasting device body is provided with an air outlet. The film pasting assembly comprises a positioning PET film, tempered glass, an adhesive layer, a protective layer and a traction belt which are arranged from top to bottom, positioning columns are arranged on the film pasting device body, and positioning holes matched with the positioning columns are formed in the positioning PET film. According to the utility model, through arranging the first elastic sheet and the second elastic sheet, the first elastic sheet and the second elastic sheet abut against the side wall of the electronic equipment, and the elastic force effect can push and press the electronic equipment towards the opposite side of the first elastic sheet or the second elastic sheet, so that the electronic product always abuts against the abutting part; the electronic equipment is prevented from deviating towards the gap side between the containing groove and the electronic equipment in the film pasting process, and the film pasting precision and the film pasting effect are improved.
