Hob die-cutting system and method for oca optical glue with four-layer 1:1 structure

Abstract

The invention relates to the technical field of optical adhesive die-cutting, in particular to a hob die-cutting system for an OCA optical adhesive with a four-layer 1:1 structure and a method. The hob die-cutting method of the OCA optical adhesive includes three parts of fitting, die-cutting and processing. Through the control of the operation process of each part, the defects of the product edgeadhesive overflowing, product warpage and the like can be avoided. According to the method, the complicating of a traditional die-cutting process is changed, process line bodies are reduced, the space occupation of the equipment is greatly reduced, the number of production and processing operators is reduced, and the number of the workers is reduced with the reducing of the line bodies; the inputof materials is reduced, and the cost of the die-cutting process is reduced; and the production efficiency of the die-cutting is greatly improved.

Description

technical field [0001] The invention relates to the technical field of optical adhesive die-cutting processing, in particular to a hob die-cutting system and method for an OCA optical adhesive with a four-layer 1:1 structure. Background technique [0002] OCA optical adhesive is one of the raw materials for important touch screens. It is made of optical acrylic adhesive without substrate, and then a layer of release film is attached to the upper and lower bottom layers. It is a double-sided adhesive tape without substrate material. It is the best adhesive for touch screen. [0003] OCA Optical Adhesive Application: It is used for the assembly of display modules, cover plates and touch screens of various structures such as Incell, Oncell, OLED, GF2, GFF, OGS, GG, etc. [0004] The existing OCA optical adhesive die-cutting methods are flat-knife die-cutting machine and hob die-cutting machine, and the structures are non-1:1 and 1:1. For the OCA optical adhesive with a 1:1 st...

AI Technical Summary

Problems solved by technology

[0004] The existing OCA optical glue die-cutting methods are flat knife die-cutting machine and hob knife die-cutting machine. Many, in the process of flat-knife die-cutting machine, there will be defects such as edge overflow and product warping, which greatly affect the efficiency of production, and in the process of some adhesive tapes, it will cause deviation and dirt.
