  • Patent number: 6145180
    Abstract: A vehicle assembly line has a first line for a first mobile conveyor and a second line for a second mobile conveyor and the first line is connected to the second line with two hanger conveyor lines. Two working robots are disposed to the first mobile conveyor, one being positioned within a cabin of an upper body section and the other being positioned in front of the upper body section. The second mobile conveyor has a mechanism for altering a posture of the upper body section and a height position thereof. To the upper body section are mounted various small parts such as grommets with the first working robot during the course of running the first mobile conveyor in the first line. The second line has plural stations for mounting larger parts such as bumpers to the upper body section which is loaded on the second mobile conveyor and whose posture and position are aligned with the working robots disposed in the plural stations before entering the stations.

  • Patent number: 5319840
    Abstract: The method involved in the present invention is directed to the coating step where an assembled unit of the upper vehicle body and the under vehicle body is coated and the upper vehicle body section is separated from the under vehicle body after coating. In the vehicle body assembly step, the vehicle body is loaded on a jig unit disposed so as to be movable through stations located along the vehicle body assembly line. Upon loading the upper vehicle body on the jig unit, the vehicle body is aligned with the jig unit on the basis of an inner member of a member for structuring the vehicle body with the aid of an aligning unit mounted to the jig unit. After coating the assembled vehicle body unit, the unit is divided into the upper vehicle body and the under vehicle body, which are then processed in separate mounting steps. After mounting various parts to each of the upper vehicle body and the under vehicle body in their own mounting lines, the upper vehicle body is combined with the under vehicle body.
