Abstract
The vehicle body assembly station comprises main transport assembly for conveying a vehicle body along a first direction D1 in which at least one assembly robot is provided to move along a second direction D2, and temporary transport assembly whose operation is more accurate than that of the main transport assembly for moving the vehicle body independently from the main transport assembly while the assembly robot is performing operations on the vehicle body, whereby a new coordinate reference system is created by the temporary transport assembly.
Claims15
A vehicle body assembly station comprising a main transport assembly for conveying a vehicle body along a first direction D1, the assembly station including at least one assembly robot arranged such that at least one part thereof can be moved along a second direction D2, wherein the assembly station further includes a temporary transport assembly, on which the assembly robot is arranged, that creates a new coordinate reference system under which the assembly robot perform operations, the operation of said temporary transport assembly being more accurate than that of the main transport assembly for moving the vehicle body independently from the main transport assembly while the assembly robot is performing operations on the vehicle body.
The assembly station of any of the preceding claims, wherein the assembly robot is arranged such that it can be displaced relative to the robot track.
The assembly station of the preceding claims, wherein said first and second directions D1, D2 are at least substantially parallel to each other.
A method for assembling a vehicle body comprising:
- conveying the vehicle body by a main transport assembly through at least one assembly station along a first direction in which at least one assembly robot is arranged such that at least one part thereof can be moved along a second direction D2,
- moving the vehicle body, by a temporary transport assembly, on which the assembly robot is arranged, whose operation is more accurate than that of the main transport assembly for moving the vehicle body independently from the main means transport assembly while the assembly robot is performing operations on the vehicle body, said temporary transport assembly creating a new coordinate reference system under which the assembly robot perform operations;
- and
- performing assembling operations on the vehicle body by at least one assembly robot.
