Robot measurement calibration system

Abstract

The invention relates to the technical field of robot calibration, in particular to a robot measurement and calibration system which comprises a measurement and calibration mechanism, a robot and a measurement head installed at the tail end of the robot. The measurement calibration mechanism comprises a base, a rack, a pedestal, a measurement table, a translation assembly, a rotation assembly and a turnover adjustment assembly. The measurement table is used for butt joint of a measurement head. The base and the rack are connected through a rotating assembly. The rack and the base are connected through an overturning adjusting assembly, the rack and the base are rotationally connected, the base and the measuring table are connected through a translation assembly, the robot measuring and calibrating system and method are compact in structure, convenient to assemble, easy to operate, wide in suitable occasion and low in manufacturing cost, coordinate information of the tail end of a robot is obtained, and the robot measuring and calibrating precision is improved. A data source is provided for performance analysis of the robot, calibration and measurement of the robot are achieved, and it is guaranteed that the obtained precision meets the application requirement while the cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of robot calibration, in particular to a robot measurement and calibration system. Background technique [0002] In recent years, more and more companies in the manufacturing industry have used robots to complete corresponding tasks such as handling, assembly, and testing. In the process of working, the robot needs to calibrate and compensate its working accuracy, so as to ensure sufficient accuracy and stability when performing tasks. Generally, when the robot leaves the factory, the manufacturer will complete the calibration of the robot first to ensure that the positioning accuracy of the robot meets the application requirements. However, with the normal use of the robot, the robot will gradually wear out, or the absolute positioning accuracy of the robot cannot be guaranteed when the robot is disassembled and reassembled when the robot fails. Usually in such a situation, the user must contact the robot...
