摘要
根据焊接机器人光电跟踪的原理和要求,设计了一种基于线阵CCD的光电跟踪系统。通过对跟踪系统光路、CCD的分析以及结构的研究,研制出的光电跟踪系统分辨率为0.05 mm,视场角为38.5°,动态检测精度可达0.06 mm。实验结果表明:该光电跟踪系统实时性好,并且可以避免焊接时弧光的干扰,能够满足多层、多道焊接时的工艺要求。
An electro-optical tracking system based on the linear array CCD is designed in accordance with the electro-optical principle and requirements of welding robot.Through the analysis of optical path,the choice of CCD,as well as the study of the structure,we have developed a electro-optical tracking system,whose resolution is 0.05 mm,field of view angle is 38.5°,dynamic measurement accuracy is up to 0.6 mm.The experimental tests show that this system has a good real-time,and can avoid interference of arc welding,it also can meet the requirements of multi-storey and multi-channel welding at the same time.
