Manufacturing method of vertical die cutting piece with irregular double-glue area

Abstract

The invention relates to a manufacturing method of a vertical die cutting piece with an irregular double-glue area. The method comprises the following steps that (1) a first-stage material belt is attached; (2) primary punching die cutting and waste discharging; (3) attaching a secondary material belt: sequentially attaching a handle film (6) and a second single-sided adhesive (7) to the double-sided adhesive (3), then attaching a silica gel belt (8) to the lower part of the single-sided adhesive (1), overturning the material belt, discharging the silica gel belt (8), the single-sided adhesive (1) and the bottom film (2), and attaching a cover film (9) to the double-sided adhesive (3) to form the secondary material belt; (4) secondary punching die cutting and waste discharging; (5) laminating a third-stage material belt; (6) third-time punching die cutting and waste discharging; and (7) laminating and rolling the die-cutting piece product: laminating partition paper (13) below the handle film (6) to form a vertical die-cutting piece with an irregular double-glue area, and rolling the vertical die-cutting piece. Compared with the prior art, the invention has the advantages of no displacement of the double faced adhesive tape, low product reject ratio and the like.

Description

Technical field [0001] The present invention relates to the field of die-cut production, specifically to an irregular double rubber area of the vertical die-cut method. Background [0002] In die-cut products, it is necessary to quickly fit the die-cut double-sided adhesive products and the products to be assembled together quickly, saving time and effort. The typesetting of products when making coils is to better adapt to automated machines. However, if the product has two rubber areas, and irregular asymmetry, when making die-cut parts, it is necessary to type the product vertically to facilitate automatic operation, but the current process will produce double-sided adhesive displacement, which is not easy to discharge, resulting in poor or scrapped products. Contents of the Invention [0003] Object of the present invention is to overcome the defects present in the above-mentioned prior art and to provide a double-sided adhesive will not displace, the product defect rate is ...

Problems solved by technology

[0005] In the die-cutting of vertical die-cut parts with irregular double-sided adhesive areas, the double-sided adhesive tape is generally die-cut to shape according to the area of ​​the double-sided adhesive tape on the final product. To avoid misalignment of the double-sided tape, the area of ​​the die-cut double-sided tape will be larger than that of the final product. However, in order to achieve the goal in one step in the existing technology, the design will make the area of ​​the double-sided tape die-cut only larger than the final product. In this way, two major problems will be caused: ①Since the die-cut parts are vertical die-cut parts, the double-sided adhesive tape is slender and relatively narrow. The double-sided adhesive to be retained is taken away by the waste release film, resulting in defective final products; ②Because the area of ​​the double-sided adhesive die-cut by the first punch is not large enough, it means that when the waste is discharged by the second punch, less double-sided adhesive is discharged. Thinner, it will be broken during waste discharge, resulting in failure to discharge and resulting in poor final products
