Abstract

The invention relates to a system and a method for grinding an industrial robot on the basis of visual information. In the system, the image of a workpiece is collected by a video camera; the workpiece is positioned by computer recognition; the movement locus points of a mechanical arm from the current position to a fetching position are planned on line to control the mechanical arm to fetch the workpiece; and then, the revolving speed and the revolving direction of an abrasive belt are controlled by a preset operation step of grinding so as to control the industrial robot to move the workpiece to an appointed position and gesture for grinding and polishing the workpiece. In the system, the video camera collects the image of the workpiece in real time; the workpiece is identified and positioned by the computer to control the mechanical arm to fetch the workpiece; the movement of the industrial robot and the running state of a grinder in the workpiece grinding operation are controlled; the data end of a computer is connected with the data end of the control cabinet of the industrial robot; output locus points controls the industrial robot to move; and the data end of the computer is connected with the data end of the grinder to control the grinder to start and stop and control the revolving speed and the revolving direction of the abrasive belt.

Description

technical field [0001] The invention relates to a grinding system, in particular to an industrial robot grinding system and method based on visual information. Background technique [0002] In the manufacturing industry, grinding and polishing is a key process, and the quality of grinding often determines the grade of the product. Traditional workpiece grinding mainly includes three modes: manual grinding, special machine tool grinding and CNC machine tool grinding. However, manual grinding has a large workload and low efficiency, and the uniformity of workpiece processing is poor; special machine tools are not versatile and are only suitable for mass production; CNC machine tools have high processing costs. In addition, the large amount of dust in the polishing workshop poses a threat to the health of workers. [0003] Industrial robots have many advantages such as high degree of automation, good flexibility, small operating space, long-term operation, programmable contro...
