Embodiment 1

[0041] A production process for mobile phone camera back glue, comprising:

[0042] A. Transfer one side of the colloid layer 200 adhered with the release paper 600 and the base material layer 300 to the first release film 100, and punch out the hole 4 in the middle of the back glue of the camera from one side of the release paper 600. The depth is greater than or equal to the sum of the thicknesses of the first release film 100 , the colloid layer 200 , the substrate layer 300 and the release paper 600 .

[0043] B. Die-cut the hand-tear position 8 of the camera back adhesive from one side of the release paper 600, the depth of the die-cut is greater than or equal to the sum of the thicknesses of the release paper 600, the substrate layer 300 and the colloid layer 200, and the depth of the die-cut is less than the release type The sum of the thicknesses of the paper 600, the substrate layer 300, the colloid layer 200 and the first release film 100.

[0044] D. Remove the rel...

Embodiment 2

[0061] The present invention relates to a kind of production process of mobile phone camera back glue, comprising: the first pass punching: transfer the 3M colloidal layer to the first layer of release film (30g peeling strength), from the 3M colloidal layer with the release paper Die-cut camera adhesive hole on that side, and the depth of punching is greater than 30g of release film, substrate layer and colloid layer with the thickness of the release paper; from the side of the 3M colloid layer with release paper, the camera back adhesive is punched The hand-tearing position is 8, and the depth of punching is to punch the 3M colloidal layer with release paper and 3M adhesive base material, and the 30g release mold cannot be punched; the process of punching the camera back adhesive hole and the hand-tearing position are 8 process knives The molds are made together, so that it can be punched completely at one time, and the waste is automatically removed on the machine, and the m...

Abstract

The invention relates to a production process of a mobile phone camera back adhesive. The production process comprises the following steps: repasting one side of an adhesive layer adhered with a piece of release paper and a substrate layer to a first release membrane layer, and punching a hole in the middle of the camera back adhesive from one side of the release paper; B, punching a tearing position of the camera back adhesive from one side of the release paper, wherein the punching depth is greater than or equal to the sum of thicknesses of the release paper, the substrate layer and the adhesive layer and is smaller than the sum of thicknesses of the release paper, the substrate layer, the adhesive layer and the release membrane layer; D, removing the release paper, and pasting a second release membrane layer; E, punching the appearance of the camera back adhesive from one side of the release membrane layer. As the adhesive is repasted to the release membranes twice, a procedure of artificial repasting of a finished product is avoided, and the rejection rate of the product is reduced; as the release membrane instead of the release paper is adhered to the lower side, the support strength of the lower part is effectively improved when the hole is punched, the situation that the adhesive layer enters a hole wall is effectively avoided, the adhesive layer is not adhered to the hole wall, and the product quality can be improved.

Description

technical field [0001] The invention relates to the technical field of camera production, in particular to a production process of mobile phone camera back glue. Background technique [0002] With the increasing popularity of electronic devices, mobile phones have become a part of people's daily life. [0003] The camera is one of the necessary standard parts of the mobile phone, and the back glue of the camera of the mobile phone must be used in the production process of the camera. [0004] The existing process adopts the following technical scheme: one side of the roll material (adhesive colloid layer) is flatly attached to the release paper (covered on the 100g release paper) → punching the product, including punching, punching the shape of the product and hand tearing position → Manual poking (remove the waste in the hole) → manual reposting. In the existing process, manual transfer is required, some colloidal layers will adhere to the hole wall, manual transfer will ...
