Background technique

Under the development trend of intelligent industrialization, the requirements for the processing and measurement accuracy of small-sized parts are increasing day by day. In high-volume industrial production, using artificial vision to inspect product quality is not only inefficient but also inaccurate. At the same time, due to individual differences and long-term fatigue work, misjudgment and omission are prone to occur, and it is difficult to avoid this situation no matter how to strengthen quality supervision.

A V-shaped part is a small part with two part pins, and the two part pins respectively constitute two straight segments of "V". The distance dimension of the opening between the pins is measured to determine whether it meets the technical specifications. If not, the distance between the openings between the pins needs to be corrected to the predetermined standard size.

The traditional correction method relies on experienced operators to take human eye readings and calculate the deviation, and finally perform manual correction, and the process of “correction-measurement-correction” needs to be repeated, which is not only inefficient and small, but also because of the long-term continuous Manual operation also makes it difficult to reduce the missed detection rate.
