Manufacturing method of curved-surface touch screen glass cover plate

Abstract

The invention discloses a manufacturing method of a curved-surface touch screen glass cover plate. The manufacturing method of the curved-surface touch screen glass cover plate comprises the following steps: (a) washing a glass substrate; (b) carrying out silk-screen printing of acid-resistant ink on the surface of one side of the glass substrate, in which the acid-resistant ink is distributed at the edges of the periphery of each touch screen glass cover plate; (c) etching; (d) cutting the glass substrate; (e) carrying out ink removal treatment on the each separated touch screen glass cover plate; and (f) carrying out CNC engraving processing on the touch screen glass cover plate according to the curved-surface requirement to obtain the curved-surface touch screen glass cover plate. According to the manufacturing method of the curved-surface touch screen glass cover plate, a single-side thinning process is used for thinning to obtain the touch screen glass cover plate with a thin middle area and thick periphery; the CNC engraving is carried out according to the curved-surface requirement on the basis to obtain the glass of the curved-surface touch screen glass cover plate; compared with the conventional method for directly carrying out CNC engraving on the glass substrate, the method is used for carrying out CNC engraving after thinning; the process difficulty is greatly reduced; the yield of the product is increased; in addition, the thinning can be carried out in batch operation; the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a method for manufacturing a glass cover plate of a curved touch screen. Background technique [0002] The touch screen glass cover is a type of glass product attached to the surface of the touch screen with beautifying decoration and protection functions. The use of touch screen glass cover makes the touch screen have high-definition visual effects, scratch resistance, pressure resistance, drop resistance, impact resistance and other excellent properties, and is widely used in touch screen products such as mobile phone screens, tablet computers, and digital photo frames. [0003] Currently, there are two types of glass cover plates used in touch screens: flat and curved. The flat glass cover is generally produced through cutting, fine carving, polishing, tempering, cleaning, coating, silk screen and other process steps. This method has a simple manufacturing process and ...

AI Technical Summary

Problems solved by technology

The production of 2.5D / 3D curved glass cover plate has higher technical requirements than that of flat glass cover plate. It needs special equipment and special process. It is difficult to make and is only used in a few high-end products.

However, at present, the production of 2.5D / 3D curved glass cover plates usually directly adopts the method of carving and polishing the glass substrate to obtain the radian. The manufacturing process is difficult, the yield rate is low, and the cost is high.
