Abstract

The invention discloses a glass protective processing technology, glass and equipment, and relates to the technical field of glass processing. The glass protective processing technology includes the following steps: cutting the sheet with protective ink layers on both sides into small pieces, and performing polishing and surface treatment to obtain processed glass; wherein the protective ink layer is obtained after the protective ink is cured. The invention alleviates the technical defect that the traditional process takes a long time to eliminate scratches, resulting in low productivity of the mill; while the short grinding time cannot completely remove the scratches caused by the previous process, resulting in low yield. The process of the present invention forms a protective ink layer on the sheet so that the entire surface of the product is protected for production and processing. The glass protection processing process can reduce mill processing time and increase productivity without affecting production yield.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a glass protective processing technology, glass and equipment. Background technique [0002] As the manufacturing process of mobile phone screen glass becomes more and more mature, the competition among various manufacturers is becoming more and more fierce. They have invested a lot of research and development costs to improve glass production bottlenecks, improve glass yield and increase production capacity. [0003] The existing mobile phone glass pre-processing process includes: cutting-fine carving-special shape-flat grinding (surface treatment)-inspection, etc. During the processing process, the product will have a lot of scratches on the surface after cutting, fine carving and special-shaped processes , it is necessary to eliminate scratches by grinding with a grinder. [0004] At present, there are the following problems in glass processing: In order to eliminate...
