Abstract

The invention relates to a photovoltaic glass edge portion defect detection system and a corresponding method. The system is installed on a production roller way of photovoltaic glass. The system comprises a mechanical frame, a light source module, a camera module and an edge portion defect detection module. A corresponding method for realizing photovoltaic glass edge portion defect detection is combined to control the system. A machine vision detection technology is used to realize the automatic detection of a photovoltaic glass edge portion. Detection accuracy can reach 0.5mm, and an omission ratio is less than 0.5%, which is obviously better than manual detection and improves the detection efficiency of the photovoltaic glass. By using the photovoltaic glass edge portion defect detection system and the corresponding method, labor force wastes can be effectively reduced, detection cost is decreased, detection precision and glass quality are increased, an automation degree of an enterprise is reinforced, large scale popularization of a glass automatic detection system can be realized, and a wide application range is achieved.

Description

technical field [0001] The invention relates to the field of image detection, in particular to the field of quality detection of photovoltaic glass, and specifically refers to a detection system for edge defects of photovoltaic glass and a corresponding method. Background technique [0002] In recent years, with the rapid growth of market demand for glass products, the production of glass products has undergone qualitative changes in terms of quality, variety, and production technology. Especially with the continuous development of production technology, the quality requirements of high-end products for glass substrates are getting higher and higher, and it is particularly important to fully ensure the quality of glass and improve its grade. [0003] The appearance, size, shape and quality of the original photovoltaic glass sheet formed and cut by the calendering process cannot meet the user's assembly and use quality requirements, so the four sides and corners of the origin...
