Wuhan's automatic imaging equipment is a high-tech equipment based on industrial computer image processing software that automatically detects, and performs screening, sorting, counting and data processing. It uses a fine visual inspection system to solve manual product quality inspection problems and improve customer satisfaction .
The automatic imaging equipment control system is generally PLC+PC. The PC computer is responsible for the operation of the machine vision inspection software, and the PLC is responsible for the operation of the control logic of the whole machine. Generally, 232 communication or IO communication is used. Those who are familiar with PLC know that PLC has a scanning cycle. It takes at least more than 10 milliseconds for a slightly larger program to run, and the communication between PC and 232 also takes a long time. Such a configuration is difficult to achieve rapid detection and screening under the new situation.
　　　 The optical image screening machine uses a CCD camera to convert the detected target into an image signal, and then converts it into a digital signal according to the pixel distribution, brightness, color and other information.
Most people think that the accuracy of the optical inspection machine configuration, in fact, the degree is also affected by the lighting and lens, most companies recommend purchasing high-precision equipment for the accuracy of the inspection, but do not forget the light source and lens Usually, according to the needs of customers, high-precision cameras will computer processing time, which affects the detection speed. When it comes to fully automatic imaging equipment, many people think of its price. For those who don’t know it, it’s easy to spend a high price to buy a machine that is not very good, which is not only a waste of money but also a waste of energy. It’s important It affects the later use. From this point of view, choosing a good machine is very important.
