Description

Mobile phone protection film convenient to operate

Technical Field

The utility model relates to a cell-phone protection pad pasting field, concretely relates to cell-phone protection pad pasting convenient to operation.

Background

In order to protect the screen of the mobile phone from being worn and scratched, the mobile phone is required to be pasted with a film after being purchased. In the related art, the film needs to be accurately positioned when being pasted, and if the mobile phone protective film cannot be accurately positioned, the pasting is easy to be askew, so that the attractiveness is affected, and the service life of the mobile phone protective film is also affected.

Chinese utility model patent with grant publication number CN208667576U discloses a mobile phone protection film, which stacks in turn from top to bottom a separation layer, a protection film layer, a positioning layer and a dustproof layer, wherein the positioning layer comprises a first positioning area and a second positioning area, and the first positioning area and the second positioning area use the determined straight line of the width of the positioning layer as the boundary line. When a user pastes a mobile phone protective film on the mobile phone screen, the user tears the dustproof layer, exposes the positioning layer on the outer side and aligns and attaches the positioning layer on the mobile phone screen; lifting the first positioning area from one end of the boundary line and pressing and pushing the release layer along the boundary line to the edge so that the protective film layer is attached to and fixed on the screen of the mobile phone, and the second positioning area still keeps the original positioning state; and then lifting the second positioning area from one end of the boundary line and starting to press and push the release layer along the boundary line to the other edge, so that the protective film layer is completely attached to the mobile phone screen, and finally tearing the release layer to finish the film attaching operation. In the film pasting process, the other part of the protective film can be attached to the mobile phone screen in a partially positioned state, so that the process of attaching the mobile phone protective film to the mobile phone screen is more accurate, and the operation is simple. The mobile phone protective film solves the problem of accurate positioning, but has the following defects in the manufacturing and using processes: 1) in order to ensure that the dust-proof layer and the positioning layer can be effectively bonded, an adhesive layer needs to be coated on the bottom surface of the positioning layer, in the manufacturing process, the boundary line between the first positioning area and the second positioning area needs to be punched, the adhesive layer is usually punched together in the punching process, the thickness of the adhesive layer is difficult to measure, the adhesive layer has certain resilience, the precision in punching is difficult to control, and even the protective film layer can be damaged in serious cases, so that the high product reject ratio is caused; 2) in the film pasting process, the glue layer has certain viscosity, and is difficult to break after being punched, so that the first positioning area is lifted along one end of the boundary line during operation and is influenced by the viscosity of the glue layer, the lifting operation of the second positioning area is influenced, the precision during film pasting operation is influenced, and the residual part of the glue layer on the bottom surface of the protective film layer is also influenced.
