Classification of machine vision inspection technology

         In order to adapt to the current development trend of Industry 4.0, machine vision inspection is an essential industrial application technology. Machine vision can replace humans for fatigue-free, non-differentiated, and unlimited detection. The classification of machine vision inspection technology is:

(1) Generally speaking, machine vision inspection technology can be distinguished according to inspection functions: positioning, defect detection, counting/loss detection, and standard measurement.

(2) Machine vision inspection technology can be divided into: online inspection system according to the carrier of its installation.

(3) According to the detection technology, there are generally three-dimensional vision detection technology, patch detection technology, standard measurement technology, OCR technology, etc.

Machine vision inspection is crucial to automatically detect product defects such as defects, blurs, chips or dents to ensure the functionality and performance of the product. Therefore, it has been widely used in product appearance inspection and dimension inspection in various major industries. For example, the visual system can be used to conduct three-dimensional inspection of products, the visual system can be used to detect the missing or offset of electronic components, the visual system can be used to distinguish colors to check for incorrect installation, etc.

Machine vision inspection technology is used in packaging inspection of pharmaceuticals, capacity inspection and outer packaging inspection in the beverage industry, cigarette label inspection and outer packaging inspection in the tobacco industry, assembly and installation inspection in the automobile manufacturing industry, printing quality inspection in the printing and printing industry, and clothing manufacturing. It has applications in appearance defect detection, micro component detection in the hardware industry, sorting system detection in the logistics industry, fruit sorting detection in the agricultural products industry, welding detection and installation positioning in the electronics manufacturing industry.

Machine vision inspection can also be used in conjunction with high-speed automated production lines to automatically inspect all products in the production line. This has a very important effect on controlling product quality and quality assurance. It can avoid the outflow of unqualified products and improve the company's core competitiveness. The company has not only achieved social benefits, but also brought substantial economic benefits to many companies.
