Machine vision is a key technology to advanced manufacturing
Industrial vision can be used to detect the surface information of products, non-contact measurement of product appearance size, to judge the coordinates of object position, to identify and judge the color and shape of objects. From the perspective of application technology, industrial vision can cooperate with robots to realize sorting, assembly, printing and other processes, as well as high-performance and precision components detection and measurement. The latter requires higher precision, but it is also difficult for human eyes to achieve and demand is also greater. Industrial vision is equivalent to giving a pair of eyes to the production process, which makes manufacturing intelligent, and opens up a new "Horizon" of intelligent manufacturing.
So, what machine vision technologies make manufacturing more "intelligent"?

The perception technology of machine vision
The machine vision technology has high self-adaptive and intelligent performance, and the imaging technology, image automatic acquisition technology, image automatic processing technology, image registration and joint control with intelligent equipment have realized outstanding perception ability. Specifically, the perception technology of machine vision can be effectively applied in the fields of product detection, precision measurement and control and automatic production line in intelligent manufacturing. Machine vision technology makes industrial robot have stronger perception ability. The eye function makes it not need to have offline programming mechanism in advance, but also can get rid of the preset motion track. Through the guidance of perception ability, it can automatically identify and process scene information, complete the disposal of grab specified objects, and make the production process more intelligent and flexible.
Dynamic monitoring and feedback technology of machine vision
In traditional production and manufacturing, although the application of automatic production line greatly improves the production efficiency, in practice, due to the complexity of the system, once the failure may affect the whole production line, resulting in the loss of product quality, enterprises will also face huge economic losses. The dynamic monitoring and feedback technology of machine vision technology solves the corresponding problems well. In visual technology, dynamic monitoring and feedback technology can monitor and feedback the production line in real time, and control the product quality errors in the production and manufacturing process. Through the application of fault tolerance, the error rate of product quality is greatly reduced, and the production defect rate can be avoided and the production defect rate can be avoided. At the same time, the industrial monitoring visual technology can realize real-time communication and feedback through closed-loop adaptive control of visual monitoring and image lossless compression. According to the test results, the position adjustment, quality screening, data statistics and so on can be automatically completed, which helps the control and overall deployment of intelligent production and manufacturing links. From the current application situation, the technology is still in the initial stage of R & D and application.
Overview of the application of machine vision technology in intelligent manufacturing
The application of machine vision technology in intelligent manufacturing involves many fields, and with the development of the research of the technology. From the current application, it involves many different fields, including medical devices, electronic manufacturing, automobile manufacturing, etc.
First, the application of machine vision technology in medical equipment industry can be used for defect detection in medical equipment industry. It can automatically screen and eliminate the quality of medical products. Combined with the automatic equipment, the appearance defects of injection needle are detected online, and the unqualified products can be eliminated automatically. Secondly, the application of machine vision technology in electronic manufacturing, such as chip must be welded with very thin welding line, and the fine aluminum or gold wire should be placed on very small cushion surface with absolute accuracy. By machine vision technology, the position of welding and processing can be well realized, and the production and processing work of high-precision point can be well completed. In addition, in the field of automobile manufacturing, machine vision system is widely used in the field of automobile manufacturing condition monitoring, finished product inspection and quality control, and the practical application effect is more and more obvious.
With the development of "machine changing" in manufacturing industry, machine vision, which is necessary for the intelligent process of equipment, will also develop rapidly. Machine vision technology is a tool that can help factories reduce pollution and get high efficiency at lower cost. It can be predicted that with the maturity and development of machine vision technology, it will be widely used in modern and future manufacturing enterprises.
