Machine vision detection systems are widely used in various fields, from medical images to remote sensing images, from industrial production detection to file processing, from nano technology to multimedia databases, almost all occasions that require human vision require machine vision detection systems, especially in some fields that require high or human vision cannot perceive, such as accurate quantitative perception, dangerous scene perception, invisible object perception, etc, The role of machine vision detection system is particularly important. Automatic detection of appearance defects requires the use of electronic component appearance detection equipment. Then, how to detect the appearance defects of electronic components?

What are the main functions of the appearance inspection system?

Visual inspection system mainly includes defect detection, which can detect various defects in products, such as size, location, existence and damage; The measurement of geometry measurement as the target object; Including identification. Size code, character text, etc.

When identifying and testing electronic components, the following operations should be followed:

1. Check that the model, specification, manufacturer and origin of components must comply with the design requirements, and the outer packaging must be intact.

2. The electrode leads of electronic components should be free of crimping and bending, and the coating should be intact and bright without oxidation and corrosion.

3. Check whether the appearance of electronic components must be intact, whether the surface has defects such as dents, scratches, cracks, etc., and whether the components with coating on the outside must be free of falling off and scratches.

4. The model and specification marks on electronic components should be clear and complete, the position and color of the color code should meet the standards, and the characters on the integrated circuit should be carefully checked.

5. The size of components of mechanical structure should be qualified, the thread should be flexible, and the rotation feel should be appropriate.

6. Switch components are flexible to operate and feel good; The connector shall have proper tightness and good contact.

The components in various electronic products have their own characteristics, and the inspection content should be determined according to the specific requirements of each component.

Machine vision inspection has a wide range of applications, such as connector appearance inspection, capacitor appearance inspection, inductor appearance inspection, resistor appearance inspection, pin pin appearance inspection, transformer appearance inspection, wafer size and appearance defect inspection, etc. The product inspection through the visual inspection system will not affect the efficiency and quality of inspection due to fatigue, and the non-contact inspection will not damage the product. While expanding the vision of human eyes, it can also maintain longer working hours.

The above is related to the appearance inspection of IC chips compiled by the core detection team. I hope it will be helpful to you.
