Accumulation body of ultrathin soft glass and manufacturing and processing method thereof

Abstract

The invention discloses an accumulation body of ultrathin soft glass and a manufacturing and processing method of the accumulation body. An upper bottom layer and a lower bottom layer which are used as substrates are white glass, and at least one group of composite layers are arranged between the white glass of the upper bottom layer and the white glass of the lower bottom layer; the composite layers are divided into two types. The first type of composite layer is composed of an adhesive layer, a buffer film layer, an adhesive layer, an ultrathin film glass, an adhesive layer, a buffer film layer, and an adhesive layer in sequence. The second composite layer sequentially comprises an adhesive layer, a buffer film layer, an adhesive layer, an ultrathin film glass layer, a buffer film layer,and an adhesive layer; and the buffer film layer is made of a structural polyurethane prepolymer adhesive. The manufacturing method of the accumulation body of the ultrathin soft glass comprises a spare part stage, an adhesive coating stage, a whole accumulation stage, a pressing and rolling stage, a curing stage, a cutting stage, an inspection stage, a packaging stage and a finished product collection stage.

Description

technical field [0001] The invention relates to the technical field of display screens of electronic products, in particular to a panel glass structure of a flexible display screen and its manufacturing technology. Background technique [0002] The display screens of electronic products such as smart phones and tablet computers with traditional technology mainly use glass cover plates, and currently, ultra-thin glass is basically used. This kind of ultra-thin glass product is too thin, and there are problems such as easy cracking when processing a single sheet, and it is almost impossible to process it. [0003] In order to solve these problems, the industry usually accumulates multiple layers of the entire ultra-thin glass, and then cuts the accumulated multi-layer glass into a locked size. The accumulation layer, that is, the accumulation of glass after coating the glue, repeated dozens of times, and then cutting processing, this technology has problems such as easy damag...

AI Technical Summary

Problems solved by technology

The accumulation layer, that is, the accumulation of glass after coating the glue, repeated dozens of times, and then cutting processing, this technology has problems such as easy damage due to rolling when making the accumulation layer, the reason is that the applied glue becomes hard and causes Cannot absorb pressurized impact

The second is the problem that the glass at the top of the laminate is fragile or has gaps when cutting the entire accumulation layer into a locked size process, which leads to an increase in the defective rate of the product

In addition, after the cutting is completed, even if the rough cutting edge is ground, there are still problems such as being easily broken by external impact due to the unevenness of the cutting surface.
