Abstract

The invention discloses a robot teaching method and system based on a vision system. The equipment installation error in robot offline program teaching is eliminated by means of acquisition and analysis of the vision system and matching optimization of a data platform. The robot teaching method and system comprises the following steps: firstly, controlling a robot to run according to the trajectory provided by an offline program; making the visual system acquire an image by following the coarse trajectory of the robot; analyzing the trajectory offset relation between the robot and a workpieceaccording to the image; analyzing and determining an optimal trajectory and trajectory correction parameters by matching processing data stored in a database through the data platform. The teaching system comprises a robot processing system, the visual system and the data platform. By applying the visual system to the teaching of the robot processing system, the problem in eliminating errors by manually optimizing the trajectory with the help of an instructor after the offline program is imported is solved. The robot performs acquisition through the visual system, and selects an optimized teaching trajectory independently by means of big data analysis and judgment, so that the teaching efficiency is high and the trajectory optimization is accurate.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a vision system-based robot teaching method and system. Background technique [0002] Industrial robots are used to realize automated production and replace laborers in complex and repetitive work, and are widely used in the field of automobile manufacturing. Industrial robots need to be taught before use. [0003] It is common for robot teaching to use an offline program combined with a teaching device. Under manual intervention, the trajectory of the robot meets the processing requirements. However, using the teaching pendant to optimize the trajectory requires a high level of skill for the operator, and the manual teaching takes a lot of time and energy, and the manual teaching is only based on visual observation and experience, and the teaching accuracy is low. Contents of the invention [0004] The purpose of the present invention is to provide a robot teachin...
