[0002] During the cutting and grinding process of the display screen, if there are slight defects in the processing of the side of the glass substrate, such as roughness and cracks, in the past, a high-definition camera was directly used to manually observe whether there are cracks or images in the image of the side surface of the glass substrate. However, this kind of picture observation work is highly repetitive and has a very close approximation. The existing patent announcement number CN117405693B discloses a touch screen screen substrate processing quality inspection equipment and method, which detects the distance of the dynamically moving glass substrate in real time through a lateral distance sensor, and drives the LED light strips in the corresponding area to "brightly" illuminate the side area of ​​the glass substrate according to the real-time detected distance of the glass substrate. The system combines the real-time detection distance, matches and analyzes the acquired image luminous flux, and judges the luminous flux state of the side of the glass substrate, thereby realizing automated and precise quality inspection after the glass substrate is cut and ground.
