Workpiece grabbing method and device based on vision system

Abstract

The invention provides a workpiece grabbing method and device based on a vision system and relates to the technical field of workpiece grabbing. The method comprises the steps that actual image information of a workpiece collected by the vision system is received and subjected to fitting comparison with preset image information of the workpiece, correction data of the actual image information andthe preset image information of the workpiece is obtained, and an actual movement path of an execution mechanism when grabbing the workpiece is analyzed according to the correction data; and the execution mechanism is controlled to move to the grabbing position along the actual movement path, and according to preset grabbing action information of the execution mechanism when grabbing the workpiece, the execution mechanism is controlled to move to grab the workpiece. By adopting a pre-processing technology in background, the data analysis volume is low, and the response and operation time of the system is greatly shortened, which helps to shorten the takt of automation production. Therefore, the production efficiency and yield of a production line are improved.

Description

technical field [0001] The invention relates to the technical field of workpiece grasping, in particular to a vision system-based workpiece grasping method and device. Background technique [0002] With the rapid development of industrial intelligent manufacturing, automation and intelligent workpiece loading and unloading have developed rapidly. One of the common equipment is to combine vision and magnetic suction tools to realize the intelligent arrangement of magnetic suction point matrix relationship to cooperate with the manipulator. Complete the grabbing work of the workpiece. This kind of equipment for intelligent vision-guided magnetic suction tools takes visual pictures. After the pictures are taken, the processor analyzes the image information in real time, and calculates the position of the workpiece and the information of the equipped magnetic suction points. Among them, in the process of analyzing the image information in real time to obtain the information of ...
