They are attached in the metal line process, where metal parts such as doors and front fenders are attached to the vehicle body assembled in the floor main process and main body assembly process.

Normally, the above-mentioned lid member is manufactured by placing the lid member in an open state manually at the mounting position of the opening of the vehicle body, and attaching the hinge member assembled at a predetermined position of the lid member to the hinge mounting position provided on the vehicle body. However, since the weight of lid members such as bonnets is relatively large, the work of attaching them to the vehicle body is very complicated.

Therefore, recently, in order to automate the bonnet installation work, for example, as described in Japanese Patent Application Laid-Open No. 62-99272, reference points provided on the vehicle body are measured to accurately detect the position of the hinge attachment part. A bonnet mounting robot is described that carries the bonnet held via a suction pad or the like into a predetermined position on the vehicle body in an open state based on the second detection data, and positions the hinge member at the hinge mounting portion.

In the above-mentioned bonnet installation robot, the bonnet is carried into a predetermined position on the car body in an open state, so the hinge member fastened to the car body is also held in an open state, that is, in a seated position with respect to the hinge mounting part, by its own weight. . Therefore, the hinge member can be easily seated on the hinge mounting portion by moving the bonnet downward without switching to the sitting position in which the hinge member is folded.
