  • Multi-station robotic welding assembly
    Patent number: 6907318
    Abstract: A multi-station robotic welding assembly includes a mounting platform, and a plurality of robots attached to the mounting platform and located in respective weld stations. Each of the robots includes an elongated movable arm and wrist. A welding torch is attached to each of the robots, and is adapted for being manipulated by the movable arm and wrist. A rotatable fixture base is located on the mounting platform, and is adapted for supporting a plurality of fixtures. Each of the fixtures is adapted for holding and positioning a workpiece for welding in respective weld stations. A base indexer is adapted for repeatedly rotating the fixture base by a predetermined degree, such that the fixtures are positioned within respective weld stations for an index interval sufficient to complete welding of the workpieces.
