in the field of intelligent manufacturing is becoming more and more important, how machine vision technology works, and why it is the right choice for process automation and quality improvement.
From the current market situation, the automatic imaging technology of machine vision has been widely used, and its application advantages in the fields of industrial production, intelligent transportation, security monitoring and so on have obviously been recognized by the majority of users. The machine vision system consists of two parts: image acquisition and image processing. It consists of core components such as light source, lens, industrial camera and image processing software. It mainly has three functions of positioning, recognition and detection. In the whole process of machine vision system imaging, high-precision system calibration is the basis and focus of high-definition imaging, and has a direct impact on the final application.
Machine vision technology is an interdisciplinary subject involving many fields such as artificial intelligence, neurobiology, psychophysics, computer science, image processing, and pattern recognition.
What is machine vision?
Definition of machine vision: Machine vision is the use of optical contactless sensing devices to automatically receive and interpret images of real scenes to obtain information to control machines or processes.Machine vision is to automatically extract information from digital images for process control or inspection of manufactured products. In order to better understand machine vision, let's take the example of our automatic vision alignment machine as an example:The visual alignment automatic plate dividing machine is designed according to the cutting principle of high-speed electric spindle without stress milling cutter. The high-speed CCD vision automatic correction system, double platform feeding, can automatically complete Mark search, automatic Offset compensation, milling cutter cutting with one button. process. The computer control system is specially designed for SMT and SMD production workshops. The programming steps are simple and simple, and the operation is simple, which can quickly improve product quality and production efficiency.
The machine vision system of the automatic plate splitter also has the function of compensating the positional components. It is especially suitable for high-precision and high-capacity PCB sub-board operations. The operation is user-friendly: pre-display path pattern, dynamic tracking display process, manual intervention process ( Suspend, continue, return to work, etc., emergency stop, etc.)
What are the advantages of machine vision?
Although human vision is best at qualitative interpretation of complex, unstructured scenes, machine vision excels at quantitative measurements of structured scenes, for example, on production lines, by virtue of speed, precision, and repeatability. Machine vision systems can detect hundreds or even thousands of components per minute. With the right resolution camera and optics, the machine vision system makes it easy to check the details of items that are too small for the human eye to see.
In addition, machine vision also prevents component damage and avoids maintenance time and cost of mechanical component wear due to the elimination of direct contact between the inspection system and the component being inspected. Machine vision also brings additional security and operational advantages by reducing manual involvement in the manufacturing process. In addition, machine vision also protects the clean room from human contamination and protects workers from the dangers of a hazardous environment.
