Protective film bonding device and bonding method

Abstract

A device for laminating a protective film, and a laminating method for the same. The device comprises: a platform (10) for supporting a substrate (1) to be laminated; a pressing board (20) disposed opposed to and above the platform (10), the pressing board comprising several first slots (21) for air passage on a surface thereof facing the platform (10), a first channel (22) communicating with all of the first slots (21), and a first air inlet hole (23), the first air inlet hole (23) being on a different surface of the pressing board (20) than the first slots (21); and a first vacuum generation device in communication with the first air inlet hole (23) and generating a vacuum suction force to attach a protective film to a surface of the pressing board (20). The platform (10) and the pressing board (20) can approach each other to laminate protective film onto a surface of the substrate (1). The technical solution reduces the probability of bubble generation during a pressing and lamination process, achieves precision lamination of protective film, eliminates creases and folding damage caused by a film lamination process, prevents particles from piercing through a film layer of a product, and meets lamination requirements for both strips and sheets.

Description

technical field [0001] The invention relates to the technical field of film bonding, in particular to a protective film bonding device and bonding method. Background technique [0002] The protective film lamination process (Top laminator) is generally after the TFE (Thin Film Encapsulation, thin film encapsulation) process or the Touch process (touch panel process). The purpose of the process is to attach a layer of PET (Polyethylene terephthalate, poly The protective film made of ethylene terephthalate) prevents the product from being damaged in the subsequent process and causing the product to be scrapped. [0003] At present, most panel manufacturers' OLED touch (organic light-emitting display touch) technology is still immature, so they will outsource the touch process, that is, make the touch panel and protective film into TP film (touch panel film).

Problems solved by technology

[0003] At present, most panel manufacturers' OLED touch (organic light-emitting display touch) technology is still immature, so they will outsource the touch process, that is, make the touch panel and protective film into TP film (touch panel film). For similar products, The existing method of using roller film sticking will easily form indentations on the product surface, and if the factory environmental control is not good, resulting in more particles (particles) on the product surface, the risk of OLED or TFE film layer being pierced will be greatly increased. Increase

In addition, the existing technology needs to purchase additional defoaming equipment, and the equipment cost is relatively expensive

Furthermore, the existing technology cannot be fully compatible with strip-shaped protective films and sheet-shaped protective films, that is, the same equipment cannot meet the attachment requirements of strip stickers and surface stickers at the same time.
