A kind of double-sided adhesive product skip small edge processing method

Abstract

The present invention relates to a method for processing double-sided tape products with small edge jumping. Specifically, the method is prepared by the following method: along the length direction of the material tape, the longitudinal typesetting and punching of the long edge is carried out. Die cutting according to the contour line of the double-sided tape product, punch out the shape of the inner glue area of ​​the product, then remove the waste in the outer glue area, and then cover the handle film; (2) Punch round holes in the grasping part of the handle film, and arrange them side by side. (3) According to the outline of the product, punch the overall shape, keep a small part of the upper part of the outline without punching, punch out most of the lower part of the product, and then remove most of the lower peripheral waste that is punched out; (4) Punching In step (3), the remaining small part of the outline is removed, and the corresponding peripheral waste is removed, that is, the double-sided adhesive product is obtained. The method can eliminate the problems that the blue film on the handle on the double-sided tape is easily hooked off, the product is easily dropped from the material tape, and the double-sided tape is displaced during waste discharge, etc., which exist in the current method of skipping the long side.

Description

technical field [0001] The invention relates to the technical field of die-cutting, in particular to a method for processing double-sided adhesive tape products with small edges. Background technique [0002] Die-cutting is a method of high-precision stamping and forming of materials according to a predetermined shape. Currently there is a figure 1 The strip-shaped double-sided tape product shown is mainly used in mobile phones and tablet computers, including the handle and the double-sided tape pasted on the handle. Paste the area, then peel off the handle. [0003] The double-sided tape product is obtained by die-cutting with a die-cutting machine, and the current method for manufacturing the product is as follows: Figure 5 , The long-side direction is used for horizontal shipment. According to this method of production and processing, there is no major difficulty in actual production, but there is still a high defect rate. lead to poor application. [0004] In order...

AI Technical Summary

Problems solved by technology

[0006] If the existing processing method is directly applied to the new typesetting direction, new problems such as the product is more likely to fall from the material belt during production, and the product size is poor, and the double-sided tape is prone to shift during waste discharge.
