The board surface defect detection system is designed for companies that have requirements for appearance quality in the board production process. This system can replace more than 95% of the work of manual inspectors. The accuracy is much higher than that of human eyes, and the detection rate and accuracy are better than manual inspectors. Thermo Fisher's SIMV plate surface defect detection system can perform online detection while the strip is running at high speed, detect defects in a timely manner and alarm, eliminating the missed detection of defective products. The plate surface defect detection system has become an indispensable part of the online production quality control of modern strip steel enterprises.

【Detection Principle】

　　The system uses the lighting detection method of strong light transmission to perform systematic shooting. The system uses a high-bright industrial LED linear condenser cold light source to illuminate the steel strip under the stable operation of the steel strip (without contact) (through the divergence effect of the strong light through the aperture light. The stronger the light, the greater the divergence effect of the light). Stronger, the higher the detection accuracy), the CCD camera performs synchronous scanning on the other side of the steel strip. When holes or edge cracks appear on the surface of the steel strip, the camera collects imaging pictures of the light passing through the holes, and compares the grayscale differences. Come discover the holes. At the same time, SIMV pinhole image analysis software is used to accurately calculate pinhole size, area, diameter, distribution location and other information.

【Detection Parameters】

　　Detection objects: tin plate, galvanized plate, chrome plate, tinplate, cold rolled plate, hot rolled plate, etc.

　　Detect defects: pinholes, edge cracks, wavy edges and other defects

　　Detection range: Customized according to the width of the production line (adaptable to any width)

　　Detection accuracy: 0.1mm~1mm (depends on the number of cameras, production line width and vehicle speed)

　　Software function: Completely customized detection requirements according to user requirements
