[0002] With the continuous progress of society and the rapid development of science and technology, the market demand for many products is increasing, and the requirements are getting higher and higher. Therefore, it is necessary to ensure product quality and improve production efficiency to meet market demand. Stamping is a forming method that relies on presses and dies to apply external forces to plates, strips, pipes and profiles to produce plastic deformation or separation, thereby obtaining stamping parts of the required shape and size. Compared with castings and forgings, stamping parts are thin, uniform, light and strong. They also have the advantages of high processing efficiency, ability to realize processing of complex sizes, simple operation, high strength, stable quality and good performance. They are widely used in various fields of the national economy.

[0003] At present, stamping parts usually need to be inspected after processing to check whether the product's appearance dimensions meet the standards, whether there are any deformations, dirt, solder joint misalignment, scratches and other undesirable phenomena on the appearance, so as to determine whether the product is qualified, such as some parts of 3C electronic products (i.e. Computer, Communication and Consumer Electronic). However, for the inspection of stamping parts, the traditional inspection method that relies solely on manual measurement jigs, etc., occupies a lot of manpower, takes a long time, has high labor intensity, is inconvenient to operate, is not conducive to production control, has poor inspection accuracy, and inspectors are prone to fatigue after working for a long time, which is prone to missed inspections and misjudgments, especially for smaller, irregularly shaped or complexly structured products, which affects the overall quality of the product, has low production efficiency, high production costs, and reduces the competitiveness of the product.
