Abstract

The invention relates to a 3D curved surface ultra-thin glass processing technology and an edge etching jig. The processing technology comprises the following steps: 1) cutting: cutting a large glass plate into a plurality of glass plates with preset sizes; 2) hot bending forming: putting the glass plate into a hot bending machine for hot bending forming to form a 3D glass cover plates; 3) double-sided thinning: putting the 3D glass cover plates into acid liquor for double-sided thinning; 4) edge treatment: treating the edge of the thinned 3D glass cover plates in the modes of laser cutting, edge polishing and chemical etching; 5) chemical tempering: chemically tempering the 3D glass cover plates to improve the strength and flexibility of the surface; 6) surface etching: performing micro-etching treatment on the surface of the tempered 3D glass cover plates; and 7) ultrasonic cleaning and drying. The technology has the beneficial effects that: the process flow is reasonable, the processing efficiency is high, the processed product has relatively high impact resistance, the yield of the product is improved, and the technology is convenient to popularize and apply.

Description

Technical field [0001] The invention relates to the technical field of 3D curved glass processing materials, and in particular to a 3D curved ultra-thin glass processing technology and edge etching fixture. Background technique [0002] Ultra-Thin Glass (UTG) refers to glass with a thickness less than 100 μm and is flexible. UTG is widely used in various electronic industries due to its high transparency, stability and impact resistance. It is easy to bend. The characteristics have set a major milestone for the folding display industry, becoming an important player in the field of foldable flexible covers after the CPI cover. [0003] The overall thickness of UTG currently produced by various processing manufacturers is 20-70μm, and the glass is flat. The impact resistance on the glass surface is low, and the energy consumption is high when used in electronic equipment. The current flat UTG cannot meet consumers’ requirements for screens. Showing the pursuit of perfection o...
