Description

Technical Field

[0001] The present invention relates to the technical field of online visual inspection, and in particular to an online visual inspection device for punching of stamped parts. Background Art

[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining a workpiece (stamping) of the desired shape and size. Compared with castings and forgings, stampings are thin, uniform, light and strong. Stamping can produce workpieces with reinforcing ribs, ribs, undulations or flanging that are difficult to manufacture by other methods to improve their rigidity. Due to the use of precision molds, the workpiece accuracy can reach micron level, with high repeatability and consistent specifications, and holes, bosses, etc. can be stamped out. Cold stamping parts generally no longer undergo cutting processing, or only require a small amount of cutting processing. The precision and surface condition of hot stamping parts are lower than those of cold stamping parts, but they are still better than castings and forgings, and the amount of cutting processing is small. Such parts usually have more punching holes, including screw mounting holes, positioning holes, reinforcement process holes, ventilation and heat dissipation holes, etc. The number, aperture size, position distribution and other related parameters of each punching hole have an important influence on the performance indicators of the stamping parts, especially the punching holes in key parts, which must undergo strict inspection before leaving the factory. When inspecting the punching holes of stamping parts, a visual inspection device is required.

[0003] For visual inspection of this type of stamping parts, the stamping parts that need visual inspection are generally placed under the visual inspection probe, and the stamping parts are supported by a support structure. However, since the punching positions of different stamping parts are different and the punching angles may also be different, ordinary support structures cannot be adaptively adjusted according to the punching positions of the stamping parts, resulting in the inability to apply visual inspection of punching holes of more stamping parts.
