Abstract

The invention discloses a double-arm robot performance measuring method based on multiple laser trackers. The double-arm robot performance measuring method based on the multiple laser trackers comprises the following steps that (1-1) a double-arm robot tool coordinate system is established; (1-2) a coordinate conversion relation between base coordinate systems of the laser trackers and base coordinate systems of mechanical arms is established; (1-3) a public base coordinate system is unified; (1-4) robot performance measurement point planning is performed; (1-5) the laser trackers and an I/O synchronization technology are used for simultaneously measuring a double-arm robot; and (1-6) and data processing is performed, and a test report is generated. The double-arm robot performance measuring method has the characteristics that two arms of the double-arm robot can be simultaneously measured, the linkage characteristics of the two-arm robot can be evaluated, the movement points of the two arms do not need to be aligned in timing sequence, the measurement precision is high, and the test process is simple.

Description

technical field [0001] The invention relates to the technical field of SCARA robots, in particular to a method for measuring the performance of a dual-arm robot based on a multi-laser tracker. Background technique [0002] Robots are one of the core equipment for realizing intelligent manufacturing and digital factories. The precision requirements of robots in various application fields are getting higher and higher, and the measurement of robot performance has great practical significance for the improvement of the quality of the robot industry. At present, the national standard "GB / T 12642-2013 Industrial Robot Performance Specifications and Test Methods" is generally used for performance measurement and accuracy assurance of robots that have undergone significant changes in the factory or use environment. This performance specification mainly specifies 14 parameter indicators and corresponding test methods for determining the performance level of industrial robots for si...
