SPOT WELDING SYSTEM

摘要

A spot welding system using parallel link robots disposed close to one another. When a camera (CM) detects the arrival of a work (W) that is being conveyed, a mount moves along a guide and tracking of the work is started. Then, a parallel link having a plurality of contractile arms and robots RB1 to RB4 each having a wrist fitted to the distal end of the link start their operations. A large number of positions of the work are welded by spot welding guns G1 to G4 fitted to the wrists of these robots. The proximal end portion of each contractile arm is supported by a vertical wall of the mount in such a manner as to be capable of swinging, and each robot is so disposed as to protrude from the mount. The parallel link robots may be suspended from the mount close to one another.
