Automatic rivet pressing method and system based on machine vision and storage medium

Abstract

The invention discloses an automatic press-riveting method and system based on machine vision and a storage medium, the automatic press-riveting method ingeniously provides powerful data support and storage for a to-be-press-riveted sheet metal part by constructing a press-riveting processing database, image positioning is combined, contour and rivet hole positioning data of the to-be-press-riveted sheet metal part are collected, and the to-be-press-riveted sheet metal part is obtained. When the information is not matched, the sheet metal part information and the rivet hole layout information in the rivet pressing processing database can be called for matching, and then the rivet pressing path in the rivet pressing processing database is directly called for issuing to rivet pressing equipment for rivet pressing processing; press riveting path information with the shortest press riveting path stroke can be planned through a path algorithm matched with the scheme, finally press riveting processing, finished product inspection and data storage of non-stored qualified products are conducted on the to-be-press-riveted sheet metal part according to the actual situation, the scheme is high in processing efficiency, reliable in process matching and flexible in data updating and calling mechanism, and the method is suitable for large-scale popularization and application. And the reliability, the accuracy and the efficiency of automatic riveting work can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of pressure riveting technology and riveting processing technology, in particular to an automatic pressure riveting method, system and storage medium based on machine vision. Background technique [0002] The existing riveting machines generally only have the function of pressing riveting, and the rest are manual operations, which have problems such as low processing efficiency, low precision, high labor intensity, high repeatability, and high operational danger. In recent years, riveting is developing towards robots and flexible automated assembly systems including robot vision systems, large gantry robots, special flexible process equipment, automatic drilling and riveting machines and coordinate measuring machines. For the technology of fully automatic riveting, the technical difficulties mainly lie in how to accurately position the sheet metal parts on the lower die of the pressure riveting equipment and...
