  • Apparatus for assembling exterior parts of a motorcar
    Patent number: 5203073
    Abstract: A method and apparatus for assembling exterior parts of a motorcar wherein assembling accuracy errors of a motor car body are determined by measuring positions of a plurality of reference points of said motorcar body. Correction data is calculated relating to respective assembling positions of plural kinds of the exterior parts which form an external shape of the motorcar, the calculation being performed on the basis of measured data obtained in the previous step, while maintaining a correlative relationship among said parts, to eliminate correlative misalignment among said parts due to the assembling accuracy errors of said motorcar body. Each of said parts is then assembled by respective assembling robots to respective assembling position which has been corrected in accordance with the calculated correction data.
