As the carrier of electronic components, PCB plays an indescribable role in the modern electronics industry. It can also be called a bridge for electronic components, we can see the importance of PCB, so it is especially important to check the quality of the product during the production process. Traditional human detection is less accurate and susceptible to the influence of an individual's emotions.
Machine vision refers to a device that converts images into targets through machine vision. In image processing systems, it is converted into a digital signal based on pixel distribution, brightness, and color information. The image system performs various operations on these signals, extracts the characteristics of the target, and then controls the field device to perform a series of operations based on the judgment results.
Detection content: Detect whether the through hole on the PCB board is blocked, and send the detection result signal.
Solution. The machine vision inspection system converts the PCB board into an image signal through an industrial camera, transmits it to the image software processing system, and converts it into a digital signal based on information such as pixel distribution and brightness. Through feature location and preprocessing, the through hole is found. Calculate the total number of vias. If the through holes are clogged and the total number decreases, it is judged to be ng.
Machine vision inspection equipment can improve the inspection efficiency of products and reduce the cost of manual inspection. At present, visual inspection equipment has been widely used in electronics, PCB, new energy, film textile and other industries.
Intelligence, automation, digitalization and informatization are the major trends in the development of the manufacturing industry in the future, and Sichuan Envision is committed to the intelligent transformation and digital upgrading of manufacturing factories and enterprises.
