Visual inspection system refers to the inspection of product appearance defects. It uses advanced machine vision inspection technology to detect the stains, scratches, spots, bumps, holes, folds, defects, bubbles and other defects on the workpiece surface. In the field of industrial automation, visual appearance inspection is the core part. Visual appearance inspection technology has played an important role in object recognition, bar code recognition, product quality inspection and appearance dimension measurement, so its application range is also very wide. The following is a brief introduction to several common application scenarios.

Object measurement application

The visual appearance inspection system can quickly and accurately find the partition and confirm its position. In semiconductor packaging, the device needs to adjust the pickup head according to the chip position information obtained by the machine, and accurately select and bind the chip, which is the most basic application in the machine vision.

Object sorting application

In fact, object classification applications are based on recognition and detection, and images are processed through a visual appearance detection system to achieve sorting. In the machine vision industry, it is usually used for food classification, some parts, automatic sorting, cotton fiber sorting, etc.

Visual positioning application

The visual appearance inspection system can quickly and accurately find the partition and confirm its position. In semiconductor packaging, the device needs to adjust the pickup head according to the chip position information obtained by the machine, and accurately select and bind the chip, which is the most basic application in the machine vision.

Image detection application

Appearance inspection is one of the most important applications in the field of machine vision. Almost all products need to be tested. However, there are many defects in manual detection. The manual detection accuracy is low, and the long-time operation of the machine can not guarantee the slow detection speed, which is easy to affect the efficiency of the whole production process. Therefore, visual appearance detection equipment is also widely used in image detection; At the same time, it can also overprint the color positioning in the printing process, check the printing quality of beverage bottle caps, product packaging barcode and character recognition, and glass bottle defect detection in the color comparison and packaging process. The visual external detection system is used to detect the defects of glass bottles, including size detection, bottle appearance detection, bottle shoulder defect detection, bottle mouth detection, etc.

That's all for this article. I hope it will help you. Machine vision inspection is applied in many industries, including automobile industry, agricultural industry, printing industry, etc. However, there is no difference between machine vision inspection and machine vision positioning, just different industry titles.
