Motoman Robots Arc Welding and Handling

Two Motoman UP130 robots position parts for welding by two UP6 robots in a highly flexible workcell that processes axle assemblies. One teach pendant is used to program all four robots.Automotive Axle Assemblies

Cycle time achieved. System does not allow incorrect parts to be loaded. New part assemblies are easily added to the system. Robot programs are shifted from basic programs. This allows the cell to weld an infinite number of part sizes and part variations, vs. taught-path programming.

Fixtures/Tooling Details

Motoman Robotics provided two custom grippers for the two UP130 handling robots. Each gripper features a two-finger module and a four-finger module used to pick up different types of components. The gripper includes an automatic compliance device to compensate for normal tube length variation. All clamps automatically open and close, and include clamp-closed switches. Motoman also provided a single set of flexible input and output fixtures. The input station holding fixture incorporate slides. Fixtures are automatically adjusted using the UP130 robots and the part holding features. The operator inputs the part number, signaling the robots to move the machine fixtures to the correct setup. Changeover typically requires less than 20 seconds to complete. A green indicator light signals the operator that the parts can be loaded for operation.
