Method of and system for assembling a plurality of parts into a unit

摘要

A plurality of pivoted robots each having both a welding gun and a transferring member for transferring a part are arranged so that the swinging locus of each pivoted robot intersects with that of at least one of the other robots. A working station is provided at the intersection of the swinging loci and the pivoted robots accomplish welding on the corresponding part at the working station and transfer it to the next station.
