At the same time, due to individual differences and long-term fatigue work, misjudgments and omissions are extremely prone to occur, and it is difficult to avoid this situation no matter how quality supervision is strengthened.

A V-shaped part is a small part with two part pins. The two part pins respectively constitute two straight segments of "V". The distance between the openings 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 is to rely on experienced operators to read with human eyes and calculate the deviation, and finally perform manual correction, and the process of "correction-measurement-correction" needs to be repeated. Not only is the operation efficiency low, but also because of long-term continuous Manual operation also makes it difficult to reduce the missed detection rate.
