Method and assembly station for vehicle body door assembly

A method for vehicle body door assembly comprising:

• positioning a vehicle body in an assembly station of a vehicle body assembly line;
• operating a robot to move a door to an initial mounting position adjacent a door opening of the vehicle body, with the vehicle body and the door each having an associated pair of hinge members each of which includes an associated pivot axis, with each hinge member of one of the pair of hinge members having a shaft defining a hole through which its associated pivot axis extends, and with each hinge member of the other pair of hinge members having a pin through which its associated pivot axis extends;
• sensing the locations of the pair of door hinge members with respect to the pair of vehicle body hinge members to determine whether the door hinge members are properly positioned longitudinally along the vehicle X axis, laterally along the vehicle Y axis and vertically along the vehicle Z axis and are also properly angularly oriented for roll i about the X axis, pitch j about the Y axis and yaw k about the Z axis with all of the pivot axes aligned with each other for respective assembly of the pair of door hinge members to the pair of vehicle body hinge members;
• then performing any necessary further operation of the robot to move the door relative to the vehicle body to properly position the pair of door hinge members with respect to the pair of vehicle body hinge members so the pivot axes of all of the hinge members are aligned with each other for assembly of the door hinge members to the vehicle body hinge members;
• and
• then performing further operation of the robot to move the door along the aligned pivot axes of the hinge members for insertion of the pins into the holes of the shafts to mount the door on the vehicle body for pivotal movement between open and closed positions with respect to the door opening.
