System and method for calibrating motion of motion module and robot

Abstract

The invention discloses a system and method for calibrating motion of a motion module and a robot, and the system comprises a calibration plate, a visual detection device, a controller and a servo motor. The servo motor controls the motion module to move according to the target coordinates issued by the controller; the visual detection device at least collects images of the motion module and the calibration plate once in the motion process of the motion module; the controller obtains actual coordinates of the motion module according to the image, obtains error coordinates according to the target coordinates and the actual coordinates and obtains an error coordinate table, the controller corrects the target coordinates through the error coordinate table to obtain corrected coordinates so as to control the servo motor to control the motion module to move to the target position according to the corrected coordinates, and then the motion module moves to the target position according to the corrected coordinates. For a large-stroke module and an equipment machine with a high precision requirement on the large-stroke module, the problems that the precision performance of the equipment machine is difficult to test, the test quantitative index is lacked, the test cost is high, the efficiency is low and the like in the development or mass production stage can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of large-stroke module equipment, in particular to a system and method for calibrating the movement of a motion module, and a robot. Background technique [0002] For large-stroke module equipment such as glue dispensers, problems such as module accuracy must be strictly considered in the development or mass production stage. In the past, professional instruments for laser calibration were often required for calibration, but the problem was that the calibration process was complicated and complicated. The economic cost is high, and it is cumbersome to carry out regular precision testing. SUMMARY OF THE INVENTION [0003] The present invention provides a system and method and a robot for calibrating the movement of a motion module, so as to solve the problems of complicated operation and high economic cost in the current calibration process, and regular accuracy detection is relatively cumbersome.
