Appearance testing is an indispensable link in the process of product inspection. In recent years, machine vision appearance testing equipment has gradually replaced traditional manual testing and become a magic weapon for major manufacturing enterprises to improve production efficiency and shipping quality. The electronic component industry is an important part of the development of the electronic information industry, and the quality requirements are very strict. So, what defect detection can machine vision appearance detection equipment be applied to electronic components? 

 What is the machine vision appearance inspection equipment? 

 Machine vision appearance detection equipment is a device that uses machine vision technology to replace the human eye with machine vision and efficiently and quickly detect the appearance defects of products. It is composed of industrial camera, light source, sensor and machine vision detection system software. It converts the ingested target into an image signal and transmits it to a special image processing system, which is converted into a digital signal according to pixel distribution, brightness, color and other information. The image system performs various calculations to extract these signals. The characteristics of the target, and then control the equipment on the site according to the results of the discrimination. 

 Machine vision appearance detection equipment is applied to the detection of appearance defects of electronic components. 

 Electronic components are the upstream products of the electronic information industry chain. They are the basis for the development of systems and terminal products such as communications, computers and networks, digital audio and video. Whether electronic components work reliably determines the normal operation of electronic equipment. Because such products are generally relatively small and have high quality requirements, it is difficult to pass large-scale manual testing, and it is necessary to use machine vision appearance detection equipment to detect appearance defects. 

 Common defects of electronic components include scratches, cracks, skewed leads, mismatched dimensions, poor printing, etc., which can be accurately detected by appearance testing equipment. 

 Machine vision appearance detection equipment can not only detect the appearance defects of electronic components, but also be applied to precision components, clothing accessories, mobile phone parts and other fields, so as to improve the automation level of production by major manufacturing enterprises and improve market efficiency.
