Strip steel and other metal strips are the main raw materials for modern life containers and other metal packaging. Due to its production process and environmental factors, the surface of strip steel is prone to defects such as pinholes, edge cracks, and wavy edges. After it is made into containers, Cause serious product quality problems. Due to the high speed of strip production and small holes, traditional human eyes cannot detect strip pinholes online. Thermo Fisher's SIMV strip pinhole detection system can conduct online detection while strips are running at high speed, and can be detected in a timely manner. It detects pinholes and calls the police to prevent the missed detection of defective products with pinholes. The strip pinhole online 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.
