Abstract
This paper studies the laser vision-based automatic trajectory planning technology for spatial intersecting joint weld. Firstly, the mathematical model of T-type off-axis non-groove intersecting joint is established, and the welding seam characteristics of the intersecting joint are analyzed. Secondly, a triangular pseudo-rotation feature pixel detection algorithm based on monocular structured light vision is proposed to realize the rapid extraction and location of spatial intersecting joint weld. Then, a laser vision-based calibration method for the workpiece coordinate system of the T-type intersecting joint is proposed, the relationship between intersecting joint workpiece coordinate system and robot base coordinate system is established, and the trajectory equation is obtained. At last, a searching discrete of chord error interpolation control algorithm is proposed to automatically discrete and plan welding torch gesture data. Experiments show that the technology can achieve higher precision location and better intersecting joint weld trajectory planning, and realize high-quality automatic weld of intersecting joint.
