Visual positioning plate searching device and method for sorting large-size workpieces

Abstract

The invention discloses a visual positioning plate searching device and method for sorting large-size workpieces, the device comprises a camera device, an end picking-up device and a control system, and the camera device and the end picking-up device are both in communication connection with the control system; the camera equipment is used for acquiring at least one image containing steel plate angular points and at least one image containing steel plate part edges and sending the images to the control system; and the control system compares the image with a preset steel plate trepanning drawing to obtain position information of the steel plate and position information corresponding to each workpiece of the steel plate, and drives the tooling to pick up the workpieces according to the position information of each workpiece. The device has the advantages of being simple in structure, high in automation degree, reasonable in arrangement and the like. The method achieved through the device has the advantages of being simple in step, small in calculation amount, convenient to execute, time-saving, efficient and the like.

Description

Technical field [0001] The present invention relates to the field of workpiece sorting technology, in particular to a large-size workpiece sorting visual positioning plate finding device and method. Background [0002] In recent years, the state has issued a number of policies to support the intelligent transformation of the manufacturing industry, and the intelligent and unmanned development of steel plate sorting production lines has gradually entered the right track. However, at the same time, for large workpieces in steel plate sorting, there are pain points such as incomplete camera shooting, diversified workpiece shapes, and incomplete cover of a picker. In order to solve these problems, the usual method is to take multiple photos to stitch together the composite, re-identify the positioning and replace the end picker according to different parts. However, multiple photo splicing leads to large calculations, time-consuming, complex processing and other issues, and there are...

AI Technical Summary

Problems solved by technology

However, multiple photo stitching results in a large amount of calculation, time-consuming, and complicated processing. There are also problems such as low efficiency and complicated logic when replacing the end picker. Therefore, a more efficient and time-saving visual recognition and positioning technology for large workpieces is urgently needed.
