Description

Technical Field

[0001] The invention relates to the technical field of glass processing, and in particular to a method for online detection of end surface roughness of a liquid crystal glass substrate. Background Art

[0002] With the continuous development of electronic technology, more and more liquid crystal displays are widely used in various electronic products. Liquid crystal displays are usually made of glass substrates. Semi-finished glass substrates need to go through precision cutting, grinding, cleaning, inspection and packaging processes before they can become qualified finished products. Among them, the grinding process is a very important process. It requires grinding sharp edges and corners to eliminate the tiny flakes and tiny cracks on the edges caused by cutting the glass substrate, so as to remove internal stress and prevent screen breakage. Therefore, display panel companies not only have strict requirements on edge cleanliness, but also have strict technical index requirements for the edge grinding quality of glass substrates. It is also one of the key factors to measure whether the glass substrate can enter the subsequent process.

[0003] At present, the end surface roughness detection method is through manual sampling, which involves sampling, cutting, offline testing and data recording. However, the manual sampling and offline testing method is random and limited. It is impossible to accurately grasp the quality and the samples need to be moved before testing, which may damage the original quality. The operation is time-consuming and inefficient. There are inevitable differences in cutting and testing by different personnel. In addition, there may be residual powder after grinding on the end surface of the substrate glass, which may lead to deviations in subsequent test results.

[0004] In summary, a method for efficiently and accurately detecting the roughness of the end surface of a glass substrate is currently needed. Summary of the invention
