Abstract

The utility model discloses a film assisting adhesion structure to assist sticking of film (10). A protection layer (20) is added on the film (10), the film (10) and the protection layer (20) are pasted through adhesive (30). The adhesive (30) pastes partial area of the film (10) and the protection layer (20). The protection layer (20) reserves a non-adhesive portion. With new technical scheme adopted, this film assisting adhesion structure solves a number of problems such as the film is difficult to hold in the process of adhesion; edge may bend when the film is relatively thin; holding upper and lower surface of the film will lead to pollution; due to insufficient strength, aligning the film with edge of screen is difficult; if the film is not thick enough, the film will insert into edge of screen to damage circuit, etc.

Description

Pad pasting is assisted sticking structure

Technical field

The utility model relates to the auxiliary sticking structure of the pad pasting that is used to protect all kinds of screens, more particularly, relates to the auxiliary sticking structure of a kind of pad pasting.

Background technology

Being used to protect the pad pasting of screen is the film that a kind of screen surface that sticks on display, mobile phone etc. is used to protect screen, can be made by base materials such as plastics.There is following shortcoming in existing various screen protection film, as: in taping process, be not easy to take; Under the situation that film relatively approaches, pinching the limit can be crooked, takes the upper and lower surface of film to pollute; Film strength is not enough, after the bending, is difficult to and the alignment of screen frame; Under the situation of thickness low LCL, film can insert the screen frame, i.e. influence attaches quality also might damage screen circuit etc.

U.S. Pat 2004075909A1 has described a kind of plated film of anti-fingerprint antireflection of plastic basis material, is specially to adhere to one deck have the film of selected wavelength 1/4th thickness to reduce catoptrical generation on plastic basis material.This technology can be used for the making of screen protection film, but does not relate to the problem of the attaching of screen protection film in this patent.

U.S. Pat 2003179455A1 has described a kind of method of making antireflection film on plastics, and similar with previous patent, the method can be used for the manufacturing of screen protection film.But in this patent, do not relate to the problem that the screen protection film attaches equally.

So just need a kind of new film structure can overcome the defective of above-mentioned pad pasting.

Specific embodiment

Further describe technical scheme of the present invention below in conjunction with accompanying drawing.

With reference to figure 1 and Fig. 2; the utility model provides a kind of pad pasting to assist sticking structure; the stickup of auxiliary pad pasting 10; wherein: on pad pasting 10, increase by a protective layer 20; pad pasting 10 and protective layer 20 are bonding mutually by bonding agent 30; the subregion of bonding agent 30 bonding pad pastings 10 and protective layer 20, protective layer 20 leaves no glue part 40.

Continuation is with reference to figure 1 and Fig. 2, and according to one embodiment of the invention, the no glue part 40 that protective layer 20 leaves can go up curved and can be used as pad pasting 10 handle of the auxiliary sticking structure of whole pad pasting in other words conj.or perhaps of taking in use.

Use the service routine of the auxiliary sticking structure of pad pasting of the present utility model as follows: 1) the no glue part 40 of at first holding on the protective layer 20 is in place pad pasting 10, such as, pad pasting 10 is installed on the screen of display 2) protective layer 20 is torn from pad pasting 10.

According to an embodiment of the present utility model; protective layer 20 is a film thick, hard; it bonds on the pad pasting 10 intensity that increases pad pasting 10 and thickness and makes that pad pasting is easy to align and can not embed in the frame at the frame with the screen that is stuck, and avoids causing the circuit under the screen to be damaged.

With reference to figure 3, Fig. 4, Fig. 5, Fig. 6, the different coating methods that it shows the bonding agent 30 of the new stickup supplementary structure of this practicality comprise at least:
