Bobbin are critical components used in various manufacturing processes, such as computers, communication and consumer electronics, etc. 3C product production. The surface quality of the bobbin is essential as any defects can affect the performance and reliability of the final product. Automated visual inspection plays a crucial role in effectively detecting these defects.
The following case study on the detection of bobbin defects is from Intsoft Technology.
Inspection content and requirements
Workpiece area detection:
Diameter 5-29 mm front bobbin area, side appearance detection
Detection content:
1. Defective surfaces on both sides of the sample can be detected, while other locations can not be detected.
2. Pins oxidized, clearly visible on the outside can be detected, the inside can not be detected.
3. Pins crooked, missing foot detection, detection of foreign objects between pins.
Note: The image of above inspection items must be clearly visible for inspection
Inspection efficiency: 100-600 pieces per minute (according to sample feeding speed).
Segmentation: Subdivision of inspection steps according to inspection content.
