Abstract

A processing method of a glass cover plate is disclosed and belongs to the technical field of glass substrate moulding. The method includes dividing a surface to be processed of the glass cover plate into zones according to the final moulding thickness, etching the zones separately by an etching process according to an order from small thickness to large thickness of the zones, and grinding small sharp corners formed in adjacent zones after etching is completed to form the glass cover plate with a curved surface structure. Processing of the glass cover plate with the curved surface structure by the method is largely reduced in processing difficulty, and the yield is largely increased than the yield of numerical control machining. The method overcomes the problems of processing methods at present for arc-shaped glass cover plates, namely the processing efficiency is low and processing precision is not liable to ensure.

Description

technical field

[0001] The invention belongs to the technical field of glass cover plate processing, and in particular relates to a method for processing a glass cover plate with an arc structure. Background technique

[0002] At present, a large number of electronic products use touch panels, and the touch panels are usually formed by coating a glass cover. For the glass cover plate, the existing processing methods usually adopt processes such as milling, chamfering, polishing, and grinding. This processing method has the advantages of convenient molding and fast processing speed for the glass cover plate with planar structure on both sides. However, for processing the glass cover plate with a curved structure, the difficulty of grinding the curved surface is far greater than that of drilling or milling the plane using traditional numerical control (CNC) technology, resulting in low processing efficiency. In the process of processing, the processing time of curved glass i...
