Abstract

The invention provides a cambered surface machining device and cambered surface machining method for 2.5D glass, and relates to the field of glass panels. The cambered surface machining device for the2.5D glass comprises a base used for placing a glass substrate, a probe used for detecting the surface height of the glass substrate, and a grinding tool used for machining the glass cambered surface, wherein the probe and the grinding tool are respectively connected with a controller. According to the cambered surface machining device, the technical problem of low machining yield, caused by thecambered surface machining method, of a 2.5D glass cambered surface can be relieved, and the purpose of increasing the cambered surface machining yield is achieved.

Description

technical field [0001] The invention relates to the field of glass panel processing, in particular to a 2.5D glass arc surface processing equipment and arc surface processing method. Background technique [0002] 2.5D glass is a kind of glass with a flat surface in the middle and a concave edge to form a curved surface. Compared with ordinary glass, 2.5D glass has a good touch and a good visual effect. At present, most mobile phone screens use 2.5D glass. [0003] In the current processing technology, the processing yield of the curved surface is only about 60%. In solving the above problems, the inventors found that in the process of processing 2.5D products with numerical control processing technology, the flatness of incoming glass substrates, deformation of the base, cleanliness of the base, and repeated positioning accuracy of the abrasive tools will all affect the machining accuracy of the abrasive tools each time. In the current processing technology, each processin...
