In the context of the Industry 4.0 era with intelligent manufacturing as the core, with the deepening of the Made in China 2025 strategy, the industrial intelligent robot industry market has shown an explosive growth momentum. Among them, machine vision, which plays the role of the "eye-catching" role of industrial robots, is indispensable! Then the machine What kind of "wisdom eyes" does vision give to industrial robots, which can greatly help industrial robots to develop their strengths on the road of industrial automation and intelligent Industry 4.0 in the future?

Why do industrial robots need a pair of "wisdom eyes"

As the core technology of industrial robots, artificial intelligence has been in a sustained and rapid development stage in the past few years. Many robots have already possessed quite high intelligence characteristics, but they are far from the level of intelligence envisioned by humans. , Rome couldn't be built in a day, and robots can't become very intelligent all at once.

The real realization of industrial automation requires highly intelligent industrial robots to replace part of human work. Obviously, if you want robots to replace human work well, the first thing to do is to make them "see". Row. When industrial robots have the ability to observe things, they can judge things well, so as to solve some problems intelligently and flexibly by themselves. Therefore, machine vision that can replace the human eye for measurement and judgment is naturally very important. The machine vision system can convert the captured target into an image signal through a machine vision product, that is, an image capture device, and transmit it to a dedicated image processing system. The morphological information of the photographed target is converted into a digital signal according to the pixel distribution, brightness, color and other information, and then the image system performs various operations on these signals to extract the characteristics of the target, and then control the scene equipment according to the result of the discrimination.

How machine vision is used in industrial applications

Machine vision is widely used in the industry and has four main functions: 1. Guidance and positioning. Visual positioning requires the machine vision system to quickly and accurately find the measured part and confirm its position. Use machine vision to position the loading and unloading materials, and guide the robotic arm to grasp accurately. Pick. In the field of semiconductor packaging, the equipment needs to adjust the pickup head according to the chip position information obtained by machine vision, accurately pick up the chip and bind it. This is the most basic application of visual positioning in the machine vision industry. 2. Appearance inspection: to detect whether there is any quality problem on the production line, this link is also the link that replaces the most labor. Speaking of the medical field involved in machine vision, its main inspections include size inspection, bottle appearance defect inspection, bottle shoulder defect inspection, bottle mouth inspection, etc. 3. High-precision detection: The precision of some products is high, reaching 0.01~0.02m or even U-level, and the human eye cannot detect it and must be completed by a machine. 4. Recognition is the use of machine vision to process, analyze and understand images to identify targets and objects in various patterns. It can achieve data traceability and collection, and is widely used in auto parts, food, medicine, etc.

In general, the characteristics of machine vision system are to improve the flexibility and automation of production. Mainly in some dangerous working environments that are not suitable for manual operation or occasions where artificial vision is difficult to meet the requirements, machine vision is often used to replace artificial vision; In the process of large-scale industrial production, the use of artificial vision to check product quality is inefficient and low in accuracy. Using machine vision inspection methods can greatly improve production efficiency and production automation. Moreover, machine vision is easy to realize information integration, which is the basic technology to realize computer integrated manufacturing.

The rapid development of China's industrial robot industry has become the top of the world. The demand for industrial upgrading from the manufacturing industry to the development of intelligent manufacturing, the huge manufacturing market scale, the promotion of the Made in China 2025 strategy, and the layout of many industries have created a "time and place favorable" for the development of industrial robots, and the manufacturing industry is competing for layout Smart factories, it can be said that the development of the robot industry is at a rapid pace. The scale of demand for the entire manufacturing industry cannot be underestimated, and the development of the industrial robot industry will certainly provide many opportunities for machine vision applications.
