Analysis of the Successful Application of Thermo Fisher's Defective Paper Surface Defect Detection System
Wuxi Thermo Fisher Scientific focuses on the field of machine vision inspection, and aims to help companies improve product quality, find product defects, save labor, and reduce manufacturing costs. The company is mainly engaged in the R & D, production and sales of high-tech industrial online measurement and control products. The company's "SIMV visual inspection system" is mainly used in strip, film, paper, non-woven fabric, glass and other plate and coil industries. The main functions include defect identification and defect positioning. , System alarm, signal feedback. The core products of Wuxi Thermo Scientific Technology Co., Ltd. include: film surface defect online detection system, non-woven stain detector, paper disease online detection system, strip surface defect detection system, etc.
The successful application of Thermo Fisher ’s Defective Paper Surface Defect Detection System is described below:
Application background of paper surface defect detection system:
In the paper production process, due to the production process and the site environment, it is easy to cause defects such as mosquitoes, holes, black spots, lines, and wrinkles on the paper surface. These defects not only affect the appearance of paper products, but more importantly reduce the performance of paper. How to detect paper defects in the production process in time, eliminate the root cause of production, and control and improve the surface quality of paper has always been the goal pursued by the paper industry.
Application principle of paper surface defect detection system:
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 thicker paper and higher surface defect detection angles, the reflection detection principle is used) and 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 the normal product, the system can find the flaws, and at the same time effectively judge and classify the flaws.
Features of paper surface defect detection system:
Objective film classification basis: to prevent defective products from flowing to customers;
Timely online quality feedback: timely adjust the production line to reduce the defective rate;
Intuitive defect map: analyze the causes of defects;
Advantages of automatic labeling: accurate positioning facilitates removal.
Wuxi Thermometer said that during the paper production process, due to various factors such as the environment and the production line, defects such as holes, mosquitoes, black spots, wrinkles, spots, and damage appeared on the paper surface, which seriously affected The quality of the product surface. Especially in the past few years, special paper, pharmaceutical packaging paper and food packaging paper have become more and more stringent on product quality requirements. In addition, high-speed production lines cannot be tested directly by human eyes. More and more paper companies have started to contact us. Cooperation. At the same time, we can customize detection solutions for users to meet the diverse needs of users.
