This invention discloses a
laser welding device and method for multi-row large battery module connectors. The
welding device includes a motion platform and
welding components. The motion platform includes a
machine base, within which a
laser system control system is installed. The
laser system control system controls the laser and the overall laser
optical path. A Y-axis module slide is installed on the
machine base, and a product positioning plate is installed on the Y-axis module. The welding components include a
fixed frame, an X-axis module, a Z-axis module, and a welding module. The welding module includes a substrate, which is fixedly mounted on the slider of the Z-axis module. The substrate has multiple sets of mounting threaded holes and mounts a galvanizing head and a depth camera. The depth camera is adjacent to the galvanizing head and separated from it by a light-blocking plate. A ring-shaped surface
light source is located directly below the depth camera for high-
contrast imaging of the welding position. The substrate is equipped with a separate welding
nozzle. This method enables high-speed, integrated, safe welding of multi-row large battery module connectors with a
large range of motion, as well as rapid and flexible
changeover.
