Diaphragm laminating device and method, display module and touch diaphragm

Abstract

The invention relates to a diaphragm laminating device and method, a display module and a touch diaphragm. The diaphragm laminating device comprises a base, a traction mechanism and a laminating mechanism. According to the diaphragm laminating device and method, when a second laminating object is laminated to a first laminating object, manual dragging and diaphragm tearing are not needed, and a protection diaphragm is gradually rolled automatically or manually through the corresponding traction mechanism, so that the labor cost is saved, the production efficiency is improved, the rate of defective products in the manual diaphragm tearing process is lowered, and the yield rate of products is improved. In the laminating process, the bending angle of the second laminating object can be stillkept smaller than 90 degrees, so that the problems of breakage of the second laminating object or breakage of surface coatings or printed ink due to excessive bending are solved, and the yield of theproduct is further better improved. The diaphragm laminating device and method are particularly suitable for laminating of large-dimension diaphragm products, and have the advantages of being high inlaminating efficiency, stable and reliable in laminating process and the like.

Description

technical field [0001] The invention relates to the technical field of product bonding, in particular to a film bonding device, a film bonding method, a display module and a touch film. Background technique [0002] The currently used non-flap type soft-to-hard or soft-to-soft film bonding process mainly adopts the method of manual tearing film bonding. The method of manual tearing and lamination requires manual stretching to hold one end of the soft laminated product, and the other end needs to be manually torn off and put away the protective film slowly during the rolling lamination process. The entire tear film laminating process needs to be very careful. A little improper operation will affect the lamination, and the intervention of manual operation will increase the risk of dust falling on the lamination surface during the lamination process. Not only that, the bending angle of the soft laminated product in the process of artificial tearing film lamination (the angle b...

AI Technical Summary

Problems solved by technology

The entire tear film bonding process needs to be very careful, and a little improper operation will affect the bonding, and the manual operation will increase the risk of dust falling on the bonding surface during the bonding process.

Not only that, the bending angle of the soft laminated product in the process of artificial tearing film lamination (the angle between the end held by manual stretching to the rolling position and the laminating forward direction) is greater than 90°, that is, the lamination During the bonding process, the upper soft laminate needs to be bent more than 90°, which increases the risk of laminate breakage and surface coating or printed ink breakage
