Problems solved by technology

Most of the existing special-shaped coated glass sheets adopt two processing techniques, one is that the glass sheet is first coated and then carved and formed, and the other is that the glass sheet is first coated and then invisible cut and formed. The former will lead to instability in the curve band of the special-shaped coated glass sheet , the film layer is easily damaged, and the forming process is relatively complicated, the production efficiency and yield rate are low, and the positioning accuracy is low, and the latter needs to be covered with UV film due to invisible cutting, which consumes a lot of UV film. The warpage of the film layer after coating has a certain influence on the quality of invisible cutting, and the film layer sometimes burns (such as Figure 5 Shown) Therefore, the requirements for coating and invisible cutting are higher

Abstract

The invention discloses a process for processing a special-shaped coated glass sheet, which comprises the following steps: first, a laser rapid cutting device cuts a special-shaped pattern on the glass sheet; second, a laser rapid cutting device cuts a number of Symmetrically distributed laser cutting leads; the third step, the laser rapid cutting equipment cuts out the frame on the glass sheet; the fourth step, cleans the glass sheet, and puts the cleaned glass sheet into the coating equipment for coating; the fifth step , remove the profiled pattern along the laser cut leads and border. The invention has the advantages of improving the production efficiency and quality of the special-shaped coated glass sheet, improving the rate of good products, ensuring the stability of the curve band of the film layer, and the like.

Description

【Technical field】 [0001] The invention relates to the technical field of processing technology for coated sheets, in particular to the technical field of processing technology for special-shaped coated glass sheets. 【Background technique】 [0002] Coated glass sheets are often used to make optical components, and special-shaped coated glass sheets are required for some optical components with special shapes. Most of the existing special-shaped coated glass sheets adopt two processing techniques, one is that the glass sheet is first coated and then carved and formed, and the other is that the glass sheet is first coated and then invisible cut and formed. The former will lead to instability in the curve band of the special-shaped coated glass sheet , the film layer is easily damaged, and the forming process is relatively complicated, the production efficiency and yield rate are low, and the positioning accuracy is low, and the latter needs to be covered with UV film due to inv...
