METHOD AND DEVICE FOR ROBOT-AIDED REMOTE LASER WELDING, WITH SIMPLIFIED CONTROL OF FOCUSING DIRECTION OF LASER BEAM

摘要

The robot of the present invention is a sheet metal structure (metal sheet structure) of the present invention relates to a device for remote laser welding, the apparatus who shape (anthropomorphous) that onto the robot wrist (wrist) are adjunct device (accessory device 3) is mounted It includes the attachment device is directed the laser beam (F) centered on the focus head (focusing head), as well as one oscillation axis (oscillation axis, 8) periphery for the laser beam emitted from the laser source (laser source) direction ( pointing direction) to include an apparatus for vibration (oscillating). During the welding process, the robot is one to move the attachment device at a given speed and a given trajectory (trajectory), part of the structure been illuminated by the laser beam (W) is the movement trajectory and speed of the accessory device 3, contained by the robot indicating the direction of the beam (F) so as to focus to move to the orbit and / or a speed that does not directly dependent on the vibration becomes.
