Method and device for adhering film on screen by shearing protective film in staggered mode

Abstract

The invention discloses a method and device for adhering a film on a screen by shearing a protective film in a staggered mode. The device comprises a base, a rolling wheel seat and a stripping roller. The method comprises the following steps: shearing the screen protective film in a staggered mode; adhering an adhering sheet and a positioning sheet on an adhering layer; and adhering the stripping roller on a release layer. An equipment positioning cavity, a sliding rail and a positioning hole are arranged on the front surface of the base of the device; the rolling wheel seat consists of a rolling wheel shell and a roller; a roller shaft seat and a sliding rail are arranged on the rolling wheel shell; the roller is arranged in the roller shaft seat; and the rolling wheel seat spans on the base and moves on the sliding rail. The method and the device have the advantages that in the link of adhering the protective film to the screen, when the stripping roller turns over a stripping layer and a product layer, the phenomenon that the product layer is stripped is avoided and operation is simple, convenient and quick; the device is accurate in positioning; adhesion is time-saving and labor-saving; and operation error is avoided even for a green hand, so the adhesion quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of sticking optical protective films, in particular to a method and a device for sticking a screen protective film. Background technique [0002] The protective film pasted on the screen adopts a three-layer type protective film. The three-layer protective film is composed of three base layers: the protective layer, the product layer and the release layer. At present, there are two methods of sticking the protective film by hand and using a simple film applicator. [0003] Sticking by manual method: first, wipe the flat screen clean, cut the protective film according to the shape of the flat screen, peel off the release layer of the protective film, align the product layer with the flat screen and paste it, after pasting, peel off the protective layer and finish paste. During the pasting process, positioning is very difficult, and air bubbles and dust impurities are easily generated between the product...

AI Technical Summary

Problems solved by technology

In the link of pasting the protective film to the screen device, multiple orderly operation steps are required to form a pasting process, wherein, when pasting, use the arc-shaped push arms on both sides of the stick wheel seat to push the stripping stick, forcing the stripping stick to turn over and release The layer and the product layer are separated by peeling and peeling. If an inexperienced novice does not operate properly, the release layer and the product layer will be separated from the protective layer at the same time, and the paste cannot continue smoothly, so that the quality of the paste is difficult to guarantee.
