Everyone knows that the core product of Supersonic is a series of products in the field of lithium battery visual inspection. Since its establishment in 2012, the company has been committed to the research in the field of machine vision. It has a deep technical accumulation in this field. In 2017, Supersonic was recognized as a Machine Vision Engineering Technology Research Center. As a company that has made great achievements in the field of machine vision, it is necessary to discuss with you what advantages machine vision has over human eyes in modern industrial applications.


In the 1970s, people used the principle of bionics to make full use of the rapidity, reliability, large storage capacity, repeatability, and high computing performance of computers, and closely cooperated with traditional detection, processing, and execution links with computer technology to realize The high intelligence of product inspection has been achieved, resulting in the concept of machine vision. Today, with the rapid development of science and technology, machine vision inspection has become a very common inspection tool in modern industrial production. Compared with the human eye, machine vision can better detect errors in the production process, better detect product quality problems, improve the efficiency and automation of industrial production, and improve the accuracy of industrial production Improvement speeds up the work process and saves time, while the effect of traditional manual inspection will be affected by factors such as employee quality, work status, experience, etc. The detection efficiency is low, and the instant fatigue of human eyes may cause a major loss, especially for Precision and subtle products, such as the detection of surface defects in lithium battery chips, are even more powerless.


Advantages of machine vision inspection over manual inspection:

1. Digitization: All measurement data generated during the machine vision work process can be copied independently or copied out through a network connection, which is convenient for statistics and analysis of the production process. At the same time, it is also possible to export the specified measurement data and generate reports after measurement, without manual addition one by one, which is undoubtedly much better than manual detection data statistics;

2. Information integration: Machine vision can complete the measurement of multiple technical parameters such as the outline, size, appearance defects, and product height of the product to be inspected at one time through the multi-station measurement method; while manual inspection is faced with different inspection contents, It can only be completed through multi-station cooperation and coordination, and different employees have different testing standards, which is very prone to false detections;

3. Cost: The initial investment of machine vision will be more, but it is a one-time investment and long-term output. Due to the rapid development of machine vision, the price will gradually decrease; while manual inspection requires long-term investment, and labor and management Costs will continue to rise. Since machines are much more efficient than manual detection, the cost of machine vision will be lower in the long run;

4. Environment: Machine vision converts the target into an image signal through the image capture device and transmits it to a special image processing system. During the process of measuring the workpiece, it does not need to contact the workpiece, so it can adapt to the harsh and dangerous production environment. It will cause contact damage to the workpiece; while manual contact detection with the workpiece is required, because it cannot cope with harsh and dangerous environments, and it will inevitably cause contact damage to the workpiece during the detection process;

5. Repeatability: The machine can complete the inspection work one by one in the same way without getting tired; on the contrary, manual long-term repetitive inspection will definitely cause fatigue, and there will be subtle differences each time the product is inspected, even if the products are identical;

6. Objectivity: Fatigue is unavoidable in manual testing. At the same time, there is a fatal flaw, which is the subjectivity brought by emotions. The testing results will change with the mood of the testing personnel; while the machine has no emotions, it brings The test results are naturally more objective and reliable;

7. Accuracy: Due to the limitations of the physical conditions of the human eye, even relying on a magnifying glass or a microscope to detect products will be affected by subjectivity, the accuracy cannot be guaranteed, and there will be differences in the standards of different inspectors; The machine has obvious advantages in accuracy, and its accuracy can reach a thousandth of an inch. And the machine is not subject to subjective control, as long as there is no difference in parameter settings, multiple machines with the same configuration can maintain the same accuracy;

8. Efficiency: The rapid development of industrial automation has greatly improved production efficiency, thus putting forward higher requirements for detection efficiency. The efficiency of manual inspection is in a fixed range and cannot be greatly improved. In the repetitive and mechanized inspection process of the assembly line, the inspectors are prone to fatigue and reduce the inspection efficiency; while machine vision can inspect products faster, especially in the production line. When detecting high-speed moving objects, the machine can improve the detection efficiency, and the speed can even reach 10-20 times that of manual labor.


The use of machine vision inspection in the production process of enterprises will greatly save the time of the enterprise. Detecting defective products and preventing defective products from being delivered to consumers will greatly increase the value of the enterprise and also make the enterprise's product profits significantly. improve.
