Spectrum detection film surface 在 Online detection system 24h real-time online detection

"In the actual production process of the film, due to the influence of various factors, defects such as holes, mosquitoes, black spots, crystal spots, scratches and spots will appear on the surface of the film, which seriously affects the quality of the film and brings unnecessary losses to the manufacturer. Human eyes often can not judge the defects timely and accurately. The fine spectrum measurement and control film surface defect online detection system can detect the surface defects produced in the production process online at high speed and accurately, and display and identify all the surface defects on the film surface. It can detect common surface defects such as dirt, stripe, damage, edge crack, wrinkle, dark spot, bright spot, edge damage, black spot, hair, mosquitoes and so on. Powerful surface defect pattern recognition function, according to the characteristics of surface defects, while giving an alarm, it will point out the equipment and process problems causing the surface defects, and guide workers to deal with them in time, so as to effectively save production costs and improve product quality. Therefore, the film defect on-line detection system has become an indispensable detection equipment in the high-speed film production line. Technical parameters of on-line detection system for fine spectrum measurement and control film surface defects: Test objects: sanitary breathable film, optical film, ethylene film, propylene film, BOPA film, laser packaging PET film, etc Production line speed: 2000m / min Inspection contents: pinholes, insects, dirt, gels, scratches, wrinkles and other typical defects. Minimum defect identification size: 0.01mm * 0.01mm Treatment method for finding defect points: alarm, automatically record the position (x, y), automatically identify the defect type, automatically save the defect picture information, and the system automatically generates the distribution map of coil defect points. Advantages of fine spectrum measurement and control film surface defect online detection system: 1. Non contact measurement will not cause any damage to the observer and the observed, so as to improve the reliability of the system. 2. It has a wide spectral response range, such as infrared measurement invisible to human eyes, which expands the visual range of human eyes. 3. Working stably for a long time, it is difficult for human beings to observe the same object for a long time, while machine vision can do measurement, analysis and recognition tasks for a long time.
