Background

The glass substrate is an indispensable member for manufacturing a display panel. In the above manufacturing process, the glass substrate needs to be transferred and moved among a plurality of devices in a large production system, and if the glass substrate has defects at the edge portions such as four corners and long sides, the glass substrate is very likely to be broken during such transfer, which may affect the production process and even cause a failure of the production system. In order to find out the glass substrate with edge defects in time to avoid entering the subsequent processes, corresponding detection devices are generally required to be arranged at the entrances and exits of the substrate conveying equipment, for example, the detection devices include a corner defect detection device for detecting a four-corner defect and a long-side defect detection device for detecting a long-side defect, the existing detection mode generally uses an optical sensor for detection, and the detection mode needs to keep a slower speed for moving the glass substrate on a conveying belt, but the existing detection mode generally arranges plate bodies on the conveying belt for detection, which may cause the situation that the distance between the two plate bodies is too close to affect the detection result.
