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
The present invention relates to photographic head production technical field, be specifically related to the production technology of a kind of mobile phone camera gum.
Background technology
Along with becoming increasingly popular of electronic equipment, mobile phone has become as the part in people's daily life.
Photographic head is one of indispensable standard component of mobile phone, must use mobile phone camera gum in producing photographic head process.
Existing technique adopts the following technical scheme that: the one side of coiled material (gum colloid layer) is smooth go up → rushes product to release paper (being layed onto 100g release paper), including punching, rushes product design and hands tears hole (waste material removing in hole), position → manually disclose → be manually posted.In existing technique, it is necessary to be manually posted, hole wall can adhere to some colloid layers, is manually posted and can cause product breakage, and hole wall adheres to colloid layer can affect product quality.

In the present embodiment, the die-cut speed of ground floor mould release membrance 100 is 1.2～2.5 times of the die-cut speed of colloid layer 200.
Embodiment two
The present invention relates to the production technology of a kind of mobile phone camera gum, including: first pass is die-cut: 3M colloid layer turns note to ground floor mould release membrance (peel strength of 30g), carry the die-cut photographic head gum hole, that face of release paper from 3M colloid layer, the die-cut degree of depth more than 30g mould release membrance, substrate layer and colloid layer carry release paper thickness and；The hands carrying the die-cut photographic head gum in that face of release paper from 3M colloid layer tears position 8, and the die-cut degree of depth is 3M colloid layer to be carried release paper and 3M gum base materials thrusts, and the release mould of 30g can not thrust；Die-cut photographic head gum hole operation is torn together with position 8 operation cutting die does with hands, thus can disposable die-cut and waste material is automatically got rid of on machine completely, coiled strip made by material, it is simple to second Punching Technology.
Second time die-cut: colloid layer carries release paper and removes, and replaces with the release mould of 50g, and from that face of 50g mould release membrance, the profile of die-cut photographic head gum, waste material is automatically got rid of on machine.This employing release mould production technology of 30g and 50g, decrease colleague's original process and first do photographic head finished product, then finished product is carried out artificial round, be manually posted and artificial this three process of waste discharge material, reduce product rejection rate, be greatly improved the artificial manufacturing cost of decreasing efficiency；Because adopting release mould rather than release paper, effectively prevent colloid layer and enter hole wall, hole wall adhesion colloid layer does not have product and peels off not get off, and removes and is posted operation, improves product quality.
The present invention is not limited to above-described embodiment, and the technical scheme of each embodiment above-mentioned of the present invention combined crosswise can form new technical scheme each other, and additionally all employings are equal to the technical scheme replacing formation, all fall within the protection domain of application claims.
