Developing of robot flexible processing system for shipbuilding profile steel

A robot flexible processing system of shipbuilding profile steel was developed. The system consists of computer integrated control and robot. An off line programming robot was used for marking and cutting of shipbuilding profile steel. In the system the deformation and position error of profile steel can be detected by precise sensors, and figure position coordinate error resulted from profile steel deformation can be compensated by modifying traveling track of robotic arm online. The practical operation results show that the system performance can meet the needs of profile steel processing.

型钢加工机器人运行轨迹偏差补偿

提出一个离线编程控制的机器人运行轨迹补偿方法,以解决通用机器人无法适应变形型钢的切割加工 难题。一个激光传感器安装在机器人臂端,在机器人执行划线、切割加工前,通过激光位移传感器对工件的形 状和位置进行检测,测量数据经数据处理转化为型钢采样点三维坐标,构建型钢实际形状的简化三维模型,并 按补偿规则计算加工图形要素补偿量,在线修正机器人运行轨迹坐标。
