Embodiment Construction
[0046] The invention provides a method for detection and screening of end face defects of ring parts, comprising the following steps:
[0047] (1) Shooting the ring part to be inspected by an optical magnifying device to obtain an optically enlarged image of the end face of the ring part to be inspected;
[0048](2) Reading the optically magnified image through a control computer, performing image processing and defect recognition on the optically magnified image, including image filtering, threshold iteration, image binarization, morphological operations, image segmentation, defect recognition, etc. , and then determine whether the ring part is qualified according to the defect situation, and send the determination result to the communication port of the control computer in the form of an order;
[0049] (3) Receive commands from the communication port of the control computer through a controller. If the ring part is unqualified, the controller controls the air pressure nozzl...
