AI Technical Summary
Existing hand sewing needle testing institutions have a problem of missing detection when the needle has light-transmitting materials such as grease on it, which affects the pass rate of testing.
A needle hole detection mechanism for hand sewing needles was designed, including a brush box, a roller structure, a flushing frame, a photoelectric detection structure, and a dust collection structure. The brush cleans the magnetic groove, the roller corrects the needle posture, the photoelectric detection and camera analyze the shape of the needle hole, and the unqualified needles are processed by a robotic arm and a recycling tank. The system is combined with a computer system for automatic screening.
It significantly improves the imaging clarity and recognition accuracy of the detection, reduces the risk of missed and false detections, and improves the overall pass rate of hand sewing needle products.
