Visual Inspection Machine Quality Control System For Li-Ion Battery Package

System Operating Parameters:

Inspection principle

The KEYE inspection system is used in conjunction with the wire drawing on the production site, but it is a relatively independent inspection station. At present, in the battery production process, the battery pole pieces are packaged and the laminated battery pack is placed in aluminum foil and packaged by equipment. The battery packs enter the conveyor line one by one, and are manually taken out from the conveyor line for double-sided appearance defect inspection.

Disadvantages of manual detection: 1. The human eye cannot measure the size detection item. 2. When manually turning over the battery pack for detection, it is easy to damage the battery pack twice. 3. Manual detection will make mistakes. Haotianchen Technology Machine vision inspection has unparalleled advantages both on equipment and self-developed software systems.

Inspection details

This system is connected with the signal of the field equipment, installed with the existing assembly line, and independent detection station. When the product arrives at the station, the robot sucks the product onto the optical glass detection platform of the equipment, and takes pictures with the camera up and down (in order to avoid the interference of the light source) , first the upper 2 cameras take pictures, the upper light source is bright; then the lower 2 cameras take pictures, the lower light source is bright), the software processes the pictures to obtain OK/NG results.

If the OK product robot picks up the product and puts it back into the water line, the product enters the next station, and if the NG product robot picks up the product and puts it into the defective product collection area, the use of this system can reduce tedious and labor-intensive manual operations, and reduce human labor. Detect errors, greatly improve the quality of product shipments, and increase the company's external competitiveness.

Camera position

The system uses four cameras, the first camera is used to detect the width of copper tabs on the front of the battery pack, the width of copper tabs, the detection of copper tabs entering the shell, the width of aluminum tabs, the width of aluminum tabs, the width of aluminum tabs, and the width of aluminum tabs. Case detection, the width of the polar tabs, the second camera is used to detect the width of the front side seal of the battery pack, the presence or absence of the bottom seal, the detection of the sealing surface, and the detection of pinching.

And the third camera is used to detect the width of the copper tabs on the back of the battery pack. , copper tab width, copper tab into the shell detection, aluminum tab glue width, aluminum tab width, aluminum tab into the shell detection, two tab width, the fourth camera is used to detect the width of the back side seal of the battery pack, the bottom Detection of seal presence, sealing surface detection, and pinch detection. The four cameras open up threads respectively, start the thread when detection is required, and suspend the thread when detection is not required.
