[0003] With the in-depth research and wide application of glass balls in various disciplines, the industry has higher and higher requirements for the quality of glass balls. To improve the quality of glass balls, it is necessary to control and reduce the defects and damage of glass balls and select glass balls without defects and damage. Therefore, efficient detection of glass ball defects and damage is of great significance and is also one of the research hotspots of scientific researchers.

[0004] At present, the damage detection of glass balls is generally done manually on a large table. This is time-consuming and labor-intensive, prone to errors, and has low detection efficiency and selection rate. Our research group has been engaged in the research of damage detection of glass materials for many years and is committed to the intelligent detection of damage of glass materials. The glass material involved in this patent application is glass balls as an example. Theoretical and experimental studies have shown that the automatic feeding system of glass balls is very important for realizing the intelligent identification and sorting of glass ball damage.
