System, method and device for detecting and removing foreign matters on surface of fine blanking die on line

Abstract

The invention belongs to the technical field of fine blanking equipment detection, and discloses a fine blanking die surface foreign matter online detection and removal system, method and device. An image data acquisition module acquires surface image data of an upper die and a lower die by using an industrial camera; the image acquisition control module controls the start and stop of the data acquisition module; the image data processing module is used for carrying out preprocessing, segmentation and texture feature extraction on the acquired mold surface image; meanwhile, starting and stopping of the foreign matter removing module are controlled; and the foreign matter removal control module removes foreign matters. According to the online detecting and removing system for the foreign matters on the surface of the fine blanking die, the foreign matters on the surface of the fine blanking die can be rapidly detected and removed, defect features of obtained image data are extracted through a computer, foreign matter recognition and detection are carried out on the defect features, and die damage and resource waste are avoided. The upper fine blanking die and the lower fine blanking die are detected at the same time through multi-angle combined light and the industrial camera, and detection is more comprehensive.

Description

technical field [0001] The invention belongs to the technical field of fine blanking detection, and in particular relates to an online detection and removal system, method and device for foreign matter on the surface of a fine blanking die. Background technique [0002] At present, fine blanking is a fine blanking method developed on the basis of ordinary stamping, and it plays a great role in the field of auto parts manufacturing. [0003] Typical structures of fine blanking dies include active convex mode structure, fixed convex mode structure and continuous fine blanking die. The fine blanking process requires accurate blanking force, blank holder force and back pressure of the fine blanking equipment. Therefore, mass production of fine blanking parts generally adopts mechanical fine blanking presses, and uses hydraulic mold frames to fine blank parts on hydraulic presses. In the fine blanking process, the metal material is precision stamped through the die. After the s...

Problems solved by technology

However, this process cannot determine whether the waste is completely removed, and metal debris is likely to be attached to the mold during the stamping process, so it is very easy to have foreign matter residues on the mold, resulting in damage to the mold and unqualified products

[0004] Through the above analysis, the existing problems and defects of the prior art are: there is no method or device for online detection or removal of foreign matter on the surface of the fine blanking die in the prior art
