Description

Lens film pasting assembly

Technical Field

The utility model relates to a cell-phone accessory field, in particular to camera lens membrane pad pasting subassembly.

Background

The existing mobile phone is generally provided with a lens for taking a picture, and a lens arranged on the lens is also easy to scratch, if the lens is scratched, the quality of the picture taken by the lens can be affected by the scratch when the picture is taken, so that a layer of toughened film (also called a lens film) is generally adhered on the lens of the mobile phone lens at present.

Because the lens area of cell-phone camera lens is little, when pasting the tempering film on the lens, need use other instruments to assist usually and paste, for example put the tempering film with tweezers and paste on the lens, however, this kind of mode of pasting makes tweezers scrape colored lens and tempering film easily, and it is not convenient yet to paste the process.

The prior chinese patent with publication number CN206663912U discloses a lens tempering film assembly, which solves the technical problems of difficult holding of the tempering film and difficult positioning when the lens tempering film is adhered. The lens toughening membrane component in the utility model No. CN206663912U comprises an upper membrane, a toughening membrane and a bottom membrane; when in use, the bottom die is torn off, then the toughened film is adhered, and finally the upper film is removed. In the structure, the adhesive force (or called as viscosity) between the toughened film and the upper film needs to be larger than that between the toughened film and the bottom film, otherwise, the toughened film is peeled off together when the bottom film is torn off, and the purpose of sequentially tearing off the bottom film and the upper film cannot be realized. One side of the bottom film of the lens film is provided with an adhesive for adhering to the surface of the lens, and the other side of the upper film of the lens film is not provided with the adhesive, so that the side of the bottom film of the lens film has higher viscosity than the side of the upper film. Therefore, the product in the utility model can often appear the situation that the upper film is peeled off before the bottom film in the use process, and the toughened film can not be conveniently pasted.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome above-mentioned prior art not enough, provide a camera lens membrane pad pasting subassembly.

The utility model provides a lens film pad pasting component, which comprises a lens film component, a retainer and a bottom film; the retainer comprises a connecting part and two clamping arms, and the two clamping arms and the connecting part are connected into a whole to form a U-shaped clamping space; the two clamping arms are provided with a first clamping surface and a second clamping surface which are arranged oppositely; the lens film assembly is in a sheet shape and comprises a protective layer and a first bonding layer; the side edge of the lens membrane component is detachably clamped in the U-shaped clamping space of the retainer; the base film is a film-like sheet and covers the first adhesive layer to prevent the first adhesive layer from being contaminated and reducing its viscosity.

The utility model has the advantages that: because the utility model discloses a centre gripping formula holder structure can ensure after getting rid of the basement membrane, can be convenient for control, aim at, makes things convenient for the camera lens membrane among the camera lens membrane module to paste equipment on in order to protect the camera lens.
