Abstract

The invention relates to an industrial robot kinematics calibration system. The industrial robot kinematics calibration system comprises a measuring device arranged at the tail end of a robot and further comprises a calibration device and a data processing device which are arranged in the robot work space. According to the device, cost is reduced, carrying and using are convenient, and the devicecan be applied to online rapid calibration of a robot on the work site. A measuring coordinate system is established on the measuring device, and the robot is calibrated; and through a method, calibration of robot body geometric parameter errors, and the conversion relation among a robot coordinate system, the measuring coordinate system and a calibration coordinate system can be achieved at the same time.

Description

Technical field [0001] The invention relates to a calibration system and a calibration method, in particular to an industrial robot kinematics calibration system and a calibration method. Background technique [0002] With the expansion of the application field of industrial robots and the promotion of offline programming technology, the requirements for the absolute positioning accuracy of robots are getting higher and higher. The industrial robot calibration technology can correct robot parameter errors at a lower cost without replacing parts. It is an efficient and practical method to improve the absolute positioning accuracy of the robot. Industrial robot calibration technology is not only an effective way to improve the absolute positioning accuracy of the robot, but also plays a very important role in the computer integrated manufacturing system. It is the basis and means to achieve offline programming and simulation tasks, evaluate the quality of robot manufacturing, and m...
