Film surface defect detection equipment can achieve 24h real-time online detection

Spectrum measurement and control film 在 Online detection system is used to detect common defects such as stains, mosquitoes, holes, impurities, etc. in the surface of various film products, and the system can promptly discover the defect information in the product surface during production process, real-time Reflecting the defective information of the surface of the production line, and performs a category treatment, completely replacing the artificial naked eye for defect testing. It has greatly saved production costs and increased production efficiency and ensuring the quality of the film. Thin film defect detection principle: The output of the visual system is not an image video signal, but the detection result (such as defects, sizes, etc.) after the calculation processing. Typically, machine visual inspection is to use the machine instead of the naked eye to measure and judge. First, the CCD camera converts the captive target to the image signal, transmitted to the dedicated image processing system, transitions to the digitized signal according to the pixel distribution and the brightness, color, and the like. The image system performs various computments for these signals to extract the target, such as: area, length, quantity, location, and the like. Finally, according to the preset tolerance and other conditional output, such as defects, size, angle, offset, number, qualified / unqualified, / uniform. After the upper machine (such as PC and PLC) obtains the test results in real time, the command motion system or I / O system performs corresponding control action (such as positioning and classification) system advantages: film surface defect detection system, through intelligent machine visual inspection, It is made up for artificial meat, consumption, consumption, low efficiency defects, high efficiency fully automatic online defect testing, real-time detection of products, so that companies can take corresponding solutions to promote efficient and rapid development.
