The invention discloses a
laser visual tracking
correction method for
welding of a non-body external shaft of a
robot. The
laser visual tracking
correction method specifically comprises the following steps that S1, before
welding is started, a power source is turned on, a
system starts to work, a program starts to run, the position of a
welding gun at the
tail end of a
robot is adjusted through the position searching function of a sensor, and the tip of the welding gun at the
tail end of the
robot runs to a current arcing point A1. The invention relates to the technical field of welding
laser correction. According to the laser visual tracking
correction method for welding of the non-body external shaft of the robot, the arcing point is searched through the position searching function in the sensor, so that the tip of the welding gun at the
tail end of the robot runs to the arcing point; compared with a traditional laser visual welding seam
tracking system, the laser visual welding seam
tracking system records the position of the robot at the arcing point and the position of the laser at the moment, and the position of the robot is compensated to realize automatic tracking of the welding gun on the welding seam position; and the laser vision welding seam
tracking system has the advantages that the
programming quantity is small, the
system is easy to understand, and only a position searching point needs to be demonstrated.
