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.
Claims14
A vehicle body assembly station comprising a main transport assembly for conveying a vehicle body along a first direction D1, at least one assembly robot arranged such that at least one part thereof can be moved along a second direction D2, and a temporary transport assembly, on which the assembly robot is arranged, that creates a new coordinate reference system under which the assembly robot performs operations, the operation of said temporary transport assembly being more accurate than that of the main transport assembly, the temporary transport assembly comprising at least one moving device displaceably mounted on corresponding robot tracks for moving the vehicle body along the second direction D2 independently from the main transport assembly while the assembly robot is performing operations on the vehicle body, with said at least one assembly robot being mounted on said corresponding robot tracks to move along said second direction D2 relative to the robot tracks under a new coordinate reference system.
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 D1 in which at least one assembly robot is mounted on corresponding robot tracks to move along a second direction D2 relative to said robot tracks under a new coordinate reference system,
- moving the vehicle body, by a temporary transport assembly that comprises at least one moving device displaceably mounted on the corresponding robot tracks whose operation is more accurate than that of the main transport assembly for moving the vehicle body along a second direction D2 independently from the main transport assembly while the assembly robot is performing operations on the vehicle body, said temporary transport assembly creating said new coordinate reference system under which the assembly robot performs operations;
- and
- performing assembling operations on the vehicle body by at least one assembly robot.
