At present, the requirement of deep processing glass on the quality of float glass raw sheets is more and more strict, if the defects are detected by sampling, the defects of the optical performance can also be generated in batches in consideration of the continuous production characteristics of the float glass, so that the defective products which are picked up by the sampling need to be traced back and forth, and the tracing work is complicated and the workload is large. Therefore, how to inspect the glass defects in real time and avoid missing inspection is a difficult point and key point for quality inspection in the glass industry, so as to reduce unnecessary waste in the aspects of operation, cost and the like, and provide corresponding quality assurance for downstream customers.
