Strip steel online surface defect detection system and detection method thereof

Abstract

The invention discloses a strip steel online surface defect detection system and a detection method thereof. The detection system comprises light sources, industrial cameras, a processor and an automatic alarm; the detection system is connected with a strip steel production line; the processor comprises an image defect recognition module, an acousto-optic alarm module, a defect positioning moduleand a result display and judgment processing module which are connected in sequence in a wireless mode; the image defect recognition module is used for recognizing pictures acquired by the industrialcameras; the defect positioning module is used for performing accurate positioning on defects on the surface of the strip steel; and the result display and judgment processing module and the automaticalarm are connected in a wired or wireless mode.

Description

Technical field: [0001] The invention relates to the technical field of strip steel product performance detection, in particular to a strip steel online surface defect detection system and a detection method thereof. Background technique: [0002] With the continuous improvement of the production demand of modern automobile manufacturing, refrigerators, air conditioners and other industries, the appearance quality requirements of home appliance panels, automobile panels, tin-plated sheets, and galvanized sheets are becoming more and more stringent. The environment is very harsh, and every process may affect the surface quality of the strip. In addition, the production speed of the strip is very fast, and the manual naked eye cannot meet the needs of automatic online detection. Once pinholes, Holes, imprints, and scratches that are not detected and removed in time, and exiled to downstream customers will bring great economic losses to the enterprise. Therefore, a system that ...

[0002] With the continuous improvement of the production demand of modern automobile manufacturing, refrigerators, air conditioners and other industries, the appearance quality requirements of home appliance panels, automobile panels, tin-plated sheets, and galvanized sheets are becoming more and more stringent. The environment is very harsh, and every process may have an impact on the surface quality of the strip. In addition, the production speed of the strip is very fast, and the manual naked eye cannot meet the needs of automatic online detection. Holes, imprints, and scratches are not detected and eliminated in time, and they are exiled to downstream customers, which will bring great economic losses to the company. Therefore, a system that can detect surface defects on-line is urgently needed
