Further, as shown in FIG. 12, the oil applicator 11 and the bolt supply section 12 perform the first step and the second step on the component C placed at the same assembly position P3. Further, as shown in FIG. 13, the oil applicator 11 and the bolt supply section 12 perform the first step and the second step on the component C placed at the same assembly position P4. Further, as shown in FIG. 14, the oil applicator 11 and the bolt supply section 12 perform the first step and the second step on the component C placed at the same assembly position P5.

Further, as shown in FIG. 15, the step of tightening the bolt B (third step) is performed on the component C placed at the assembly position P5. Further, a step of imprinting identification information on the component C placed at the assembly position P4 is executed (fourth step). Further, a step of capturing an image of identification information is performed for the component C placed at the assembly position P4 (fifth step). It should be noted that a series of steps have been completed at the assembling positions P1 to P3.

As shown in FIG. 16, a step of imprinting identification information on the component C placed at the assembly position P5 is performed (fourth step). Further, a step of capturing an image of identification information is performed for the component C placed at the assembly position P5 (fifth step). It should be noted that a series of steps have been completed at the assembling positions P1 to P4.

In the above modification, since the first step and the second step can be performed simultaneously on the part C placed at the same assembly position, it is possible to perform a series of steps for a plurality of assembly positions. The required time can be shortened more than the required time in the above embodiment.

In addition, the above-described embodiments are merely examples of specific implementations of the present disclosure, and the technical scope of the present disclosure should not be construed to be limited by these. That is, the present disclosure can be embodied in various forms without departing from its spirit or key features.

INDUSTRIAL APPLICABILITY The present disclosure is suitably used in a manufacturing line equipped with an assembling device that requires miniaturization and space saving.
