Three-dimensional positioning device for position calibration of industrial manipulator

Abstract

The invention provides a three-dimensional positioning device for position calibration of an industrial manipulator. The three-dimensional positioning device comprises a stand column base, a stand column lead screw component, an X-axis component, a Y-axis component and the like, wherein the X-axis component is fixed on the stand column lead screw component; the Y-axis component is fixed on the stand column base; and red and green laser transmitters on Z-axis straight line sliding table modules on the X-axis and the Z-axis transmit laser so as to realize coordinate calibration of the designated location of the manipulator. Compared with the traditional method, an additional device is not needed to be arranged at the tail end of the manipulator during the positioning process, and the three-dimensional positioning device is visual, simple to operate, low in cost, and convenient to mount.

Description

technical field [0001] The invention relates to a measuring device capable of detecting the three-dimensional Cartesian coordinates before and after the movement of a manipulator in a certain space, in particular to a three-dimensional positioning device for position calibration of an industrial manipulator. Background technique [0002] The manipulator is a new type of device developed in the process of mechanization and automation. It is a multifunctional machine that can be automatically positioned and controlled and can be reprogrammed to change. In the modern production process, manipulators are widely used in automatic production lines. The development and production of robots has become a new technology that has developed rapidly in the high-tech neighborhood. It further promotes the development of manipulators, making manipulators It can better realize the organic combination with mechanization and automation. Therefore, the manipulator has received the attention of...

Problems solved by technology

[0004] In the calibration process, the measurement method is an extremely important factor. Foreign countries have started research work in this area since the 1980s, and have formed a variety of measurement methods. The measurement system used for the static accuracy calibration of robots includes dual theodolite poses Measuring system, three-coordinate machine and articulated multi-rod follow-up measuring system. The systems used for robot dynamic precision calibration mainly include laser tracking system, CCD interactive measuring system, ultrasonic measuring system, position measuring system and measuring system with proximity sensor High cost and cumbersome testing methods are the main problems of these measurement systems.
