Problems solved by technology

However, in the above-mentioned process, the two concentric hole structures are die-cut separately, so when the accuracy of the positioning hole itself is problematic, it is difficult to guarantee the accuracy of the concentric structure formed by die-cutting

Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] Such as figure 1 As shown, the product involved in this embodiment includes: an adhesive layer a and a release layer b that are combined together. Wherein, the adhesive layer a is divided into a plurality of areas, and each adhesive area a1 is separately arranged. At the same time, any glue area a1 is also provided with a back glue hole a11, the number of back glue holes a11 on each glue area a1 is one or more, and the shapes of the multiple back glue ...

Abstract

The invention provides a concentric die-cutting process, which includes the following steps: S1, performing the first die-cutting from the rubber surface, cutting off waste materials in areas other than a plurality of rubber areas, and eliminating the waste materials of the rubber layer formed by die-cutting; S2, Carry out the second die-cutting from the adhesive surface to form the outer contour of the product, the adhesive holes on each adhesive area, and the positioning holes on the release film that are concentric with the corresponding adhesive holes; Adhesive layer waste and release film waste formed by the second die-cutting. The concentric die-cutting processing technology of the present invention adopts the method of cutting the whole product for products that require concentricity control. That is to say, the adhesive hole and the positioning hole of the product are cut with one knife to ensure the concentricity, and at the same time, the waste lifting treatment is carried out, and the waste lifting knife is optimized so that the waste can be extracted normally.

Description

technical field [0001] The invention relates to the technical field of die-cutting processing, in particular to a concentric die-cutting processing technology for auxiliary material die-cutting applied to mobile phones. Background technique [0002] At present, the general control range of the accuracy of existing mobile phone accessories is ±0.15mm, when it comes to products with concentricity size control. In order to ensure the accuracy of die-cutting, the small hole nesting process can be used, and the concentricity accuracy can reach ±0.12mm by using the hole punching and nesting. However, in the above-mentioned process, the two concentric hole structures are die-cut separately, so when the accuracy of the positioning hole punched by the sleeve punching itself has problems, it is difficult to ensure the accuracy of the concentric structure formed by die-cutting. Therefore, in view of the above problems, it is necessary to propose a further solution. Contents of the i...
