The stamping is a forming method in which a press and a die are used to apply external force to a plate, a strip, a pipe, a profile, etc. to cause plastic deformation or separation, thereby obtaining a workpiece (stamped part) of a desired shape and size. Stamping and forging are plastic working (or called pressure working), and are called forging and pressing. The stamped blanks are mainly hot and cold rolled steel sheets and strips. In the world, 60-70% of steel materials are plates, and most of the plates are punched to form finished products. The body, chassis, oil tank, radiator sheet, boiler steam drum, shell of container, iron core silicon steel sheet of motor and electric appliance are all made by punching. There are also a large number of stamped parts in products such as instruments, household appliances, bicycles, office machines, and household utensils.

During the stamping process of parts on an automobile, parts such as an air deflector and the like need to be punched, the punching is mainly processed through a punching machine, the punching after the processing needs to detect the position degree of the punching, the existing detection mode is to manually detect the parts after the punching by workers, and the efficiency is low due to the detection mode.
