To provide a wheel assembling robot carrying system which solves at least one of the following inconveniences: (1) a workpiece carried by a feeder or a roller conveyor in a conventional carrying system is occasionally positioned to a location deviated from a correct location; (2) when each component machine goes out of order, its repairing is difficult; and (3) the number of auxiliary feeders is increased.

According to the wheel assembling robot carrying system 10, multi-purpose robots 20 are arranged at locations A, B, C, D between a rim welding portion positioning station 11, a rim welding portion helium leakage test station 12, a rim valve piercing station 13, a station 14 of a rim valve hole coin and rim tentative insertion into a disk, and a station 15 of rim permanent insertion into the disk, respectively. Then transportation and positioning of the workpiece 30 between the stations are carried out by the multi-purpose robots 20.
