Motoman Robot Spot Welding

Motoman ES165N “Expert Spot” welding robot spot welds automotive panel and rail assemblies fixtured on a dual-headstock/tailstock trunnion positioner.Automotive Panel and Rail Assemblies

Motoman Robotics provided a robotic spot welding solution that met or exceeded project goals and objectives. Robot system is able to reach around fixtures to spot weld in tight areas on two different planes. Robot system achieves or is slightly faster than required cycle time of 94 spot welds in 211 seconds for panel assemblies and 56 spot welds in 119 seconds for rail assemblies.

Fixtures/Tooling Details

Motoman Robotics provided four fixtures. One spanner fixture frame is for the panel and rail subassembly fixtures and the other is for the panel and rail final assembly fixtures. The two subassembly fixtures are located on one side of the dual headstock/tailstock trunnion positioner and the two final assembly fixtures are located on the opposite side. The panel assembly fixtures include locating details and sensing for nut plates. Fixtures are pneumatically clamped, and include part-present and clamp-closed sensors.
