[0002] Stamping processing is a production technology that uses the pressure of stamping equipment to separate the plate in the stamping die, thereby obtaining product parts of a certain shape and size. It has the characteristics of intelligence, precision, high efficiency, and high speed. However, in the stamping production process , there will always be waste products caused by objective factors such as processing errors, material defects, and mold damage. If they cannot be detected and eliminated in time, it will seriously affect the subsequent assembly and other links, resulting in a decline in the overall quality of the product and an increase in costs. , affecting production efficiency, but the existing detection device has a low degree of automation, which not only increases the consumption of manpower, but also reduces the detection efficiency. Therefore, we propose a surface defect detection device for stamping parts based on machine vision
