Analysis of 24h real-time on-line detection principle of paper defect online detection system——Wuxi Thermo Scientific Technology Co., Ltd.
Machine vision technology-based SIMV paper surface defect detection system scans the paper surface through a line scan camera, and cooperates with the SIMV paper surface defect detection system independently developed by Thermovision to quickly identify defects, automatically classify the defects, and alert when defects are found And marking is performed to achieve 100% paper defect detection, which greatly improves production efficiency.
Machine vision technology can achieve the advantages of high-speed, accurate, and online inspection in surface quality inspection. At present, machine vision technology has been widely used in strip, film, non-woven fabric, paper and other fields, and it is favored by industry users and its cost is low. , High precision, easy installation and other advantages are not to mention, has become a sharp weapon in the fields of automated production testing, quality control and so on. Based on machine vision technology, the SIMV paper surface defect detection system provides a good solution for paper quality inspection.
For normal paper, the whiteness is above 70%, and the whiteness of the pulp slurry is generally less than 30%. The detection of whiteness can be measured by various optical detection instruments. As paper measurement currently requires dynamic detection during high-speed operation, a fast detection device must be used, and the application system in the prior art scheme is the most ideal choice. Machine vision technology-based SIMV paper surface defect detection system scans the paper surface through a line scan camera, and cooperates with the SIMV paper surface defect detection system independently developed by Thermovision to quickly identify defects, automatically classify the defects, and alert when defects are found And marking is performed to achieve 100% paper defect detection, which greatly improves production efficiency.
When the production line is in normal production, the bright LED linear condensing cold light source uses the transmission principle to illuminate the product surface (for paper products with thick paper and high surface defect detection angles, the reflection detection principle is used), and it is set up on the production line The line scan camera performs real-time synchronous scanning. At the same time, the system uses the SIMV image processing unit to perform defect segmentation processing on the paper disease images collected by the camera. Because the grayscale of the defective image is significantly different from the grayscale of a normal product, the system can find the flaws, and at the same time effectively judge and classify the flaws.
Detection objects: newsprint, special paper, coated paper, white paper, art paper, cultural paper, cigarette paper, laser paper, etc.
Typical flaws: scratches, bright spots, breakage, dark spots, holes, wrinkles, oil spots, etc.
Detection width: any width (different widths can be satisfied by the combination of cameras)
Detection speed: MAX2000m / min
Detection accuracy: 0.2mm ~ 2mm (depending on detection speed and number of cameras)
Defect identification: sound and light alarm, real-time labeling, real-time display of defect coordinate information distribution map
