Industrial surface defect detection is an important part of machine vision inspection. The accuracy of detection directly affects the output quality of products. Machine vision surface defect detection technology has overcome the existing problems of manual detection, and is widely used to promote the high-quality production of enterprise factory products and the development of intelligent automation of manufacturing industry.
Characteristics of industrial surface defect detection technology based on machine vision
Can error result information file, including the corresponding error image, and can print out.
The speed of the camera automatically matches the speed of the object to be measured, and the ideal image is captured;
Real time display detection screen, Chinese interface, can browse the image of unqualified products several times, with the function of storing and real-time viewing the wrong workpiece image;
The size range of parts is 2.4mm to 12mm, and the thickness can be different;
The system can self check whether the status of its main equipment is normal and equipped with status indicator; at the same time, it can set different operation permissions for system maintenance personnel and users;
According to the operator, the system selects the workpiece with different sizes, calls the corresponding visual program to detect the size, and outputs the results;
It has the function of timely and accurately sending out the rejection control signal to the wrong workpiece and eliminating the waste products;
The rate of missing inspection was 0;
For parts of different sizes, the sorting device and conveying device can adjust the width of the material channel accurately, so that the parts can move on the fixed path and carry out visual inspection;
The system can monitor the detection process by displaying images, and dynamically view the detection results through the detection data displayed on the interface;
The resolution of the machine vision system is 2448 × 2048, and the dynamic detection accuracy is 0.02mm;
Industrial surface defect detection technology is mainly applied to 3C product appearance defect detection system, which can be applied to mobile phone shell, mobile phone glass cover, size detection, mobile phone accessories, mouse appearance, notebook pad, keyboard defects, keyboard flatness, notebook internal defects and other electronic products detection.
The appearance of machine vision inspection technology greatly improves the efficiency of production, avoids the influence of operation conditions, subjective judgment and other factors on the accuracy of the detection results, so as to achieve better and more accurate surface defect detection and more rapid identification of product surface defects.
