摘要:为了使机器人适用于不同的领域,工业机器人工具中心点(Tool Center Point,TCP)默认在第六轴末端法兰盘端面的中心,生产中根据不同需求安装相应工具,同时需要对安装工具或夹具的工具中心点进行标定来建立工具坐标系,笔者结合常用的接触式“六点法”,设计了一种提高标定精度、标定效率的自标定精度叠加方法,此标定方法仅依靠机器人自身系统,而不需借助任何辅助设备或仪器即可实现工具坐标的高精度、高效率的标定,且标定过程简单,易于操作、便于生产,解决了“六点法”自标定操作难度大、效率低及对操作者操作水平要求高等问题。

Abstract:In order to make the robots be used in same domain issues, the TPC of the industrial robot is tacitly approved installing on the central of the end of the sixth axel’s flange face. Due to different requirements, different tools should be installed; meanwhile, it is necessary to calibrate the tool center point of the tool or fixture. Combined with the commonly used contact "six point method", a new method named “Self calibration precision superposition method” is proposed by author to improve the calibration accuracy and calibration efficiency. This calibration method only depends on the self-system of robot without any accessory equipment or instrument, will achieve high-precision, high efficiency calibration of tool coordination. Furthermore, the processes is simple, easy to operate and produce, then to resolve the problems of great difficulty, low efficiency and high requirement for operators on self calibration operation.
Key words:industrial robot;TCP;self calibration;six point method
