Abstract

The invention relates to the technical field of mobile phone glass processing, in particular to a treatment process of 2.5D mobile phone glass. The treatment process comprises the following steps: (a)cleaning 2.5D glass and then drying; (b) carrying out enhanced treatment on the edge of the 2.5D glass; (c) cutting to the required size and then carrying out edging treatment; (d) carrying out toughening treatment on the edged 2.5D glass; (e) carrying out silk screen printing on the toughened 2.5D glass; (f) baking the 2.5D glass subjected to silk screen printing; and (g) carrying out coating treatment on the surface of the 2.5D glass. Compared with the prior art, the treatment process disclosed by the invention has the advantages that the edge of the 2.5D glass is subjected to the enhancedtreatment, so that microcracks on the edge, clearances between the edges, broken edges and the like are eliminated. By adopting the steps, the integral strength of the 2.5D glass can be greatly improved, and the service life is prolonged. The treatment process disclosed by the invention is simple in treatment step and easy to operate and can better meet the batch production demand.

Description

technical field [0001] The invention relates to the technical field of mobile phone glass processing, in particular to a treatment process for 2.5D mobile phone glass. Background technique [0002] 2.5D glass is a kind of glass whose front is flat and the edge part is sunken downward to form a curved shape. Compared with ordinary glass, 2.5D glass has a good touch and good visual effect. At present, most mobile phone screens use 2.5D glass, and the front casing assembly is formed by 2.5D glass and the casing. [0003] In the existing technology, most of the 2.5D glass used in mobile phones has the following problems: 1) The curved edge of 2.5D glass is thin and weak, and is prone to micro-cracks, chipping and chipping. When the mobile phone falls, the glass is very easy to 3) The existing 2.5D glass manufacturing process is complicated, which is not conducive to actual production needs. Contents of the invention [0004] In view of the above-mentioned technical problems ...
