Description

Technical Field

[0001] The utility model relates to the field of precision stamping, in particular to a full-automatic stamping continuous material online machine vision detection device. 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 of the desired shape and size. Compared with castings and forgings, stamping parts are thin, uniform, light and strong. Due to the use of precision molds, the workpieces have high repetition accuracy and consistent specifications, and the precision requirements for stamping parts are also high. Therefore, in the process of continuous material precision stamping, precision stamping parts need to be tested to ensure the accuracy and quality of stamping parts.

[0003] Existing continuous material precision stamping inspection relies on manual online sampling, which has low efficiency and unstable inspection quality. There is also single-sided automatic visual inspection for real-time monitoring of continuous material stamping production, but the inspection cannot cover the entire product. Even if it is improved to be able to inspect the top and bottom, when stamping continuous materials, the shapes and sizes of the stamped parts are different due to different stamping dies. Therefore, the guiding structure cannot be adjusted according to its size during transportation, making it difficult to play a good guiding role, thereby affecting the accuracy of the inspection and causing a large number of defective or waste products to flow out.
