[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness assembling apparatus, and more particularly to a wire harness assembling apparatus, which is capable of accurately positioning a starting position of tape winding of an electric wire at a specified position shown in a design instruction diagram so as to perform tape winding. Things.

[0002]

2. Description of the Related Art Conventionally, a wire harness has been assembled using an assembling apparatus in which wiring jigs 1 and 2 for holding and guiding an electric wire are mounted on an assembling work table 4 as shown in FIGS.

A full-size assembly drawing (hereinafter, referred to as a full-size drawing) created on the assembly work table 4 based on a design instruction diagram.
The wiring jigs 1 and 2 are erected at prescribed positions shown in the original size drawing.

FIG. 7A is a design instruction diagram of the wire harness shown in FIGS. The design instruction diagram schematically shows the wire harness to be assembled. The branch position of the branch line (b) branching from the trunk line (a), the branch lines (c), (d), and (e) further branch from the branch line (b). 3) shows the branch position (reference point p) of (f), the dimensions up to the terminal connector 3, the instruction of tape winding, and the like. At the manufacturing site, an original drawing shown in FIG. 7 (B) is created based on the design instruction diagram, this is glued on the assembly work table 4, and the wiring jigs 1, 2 are erected at predetermined positions. The wires are wired by holding and guiding the wires to the wiring jigs 1 and 2, and a predetermined assembling operation such as tape winding is performed.

[0005] Incidentally, the original size drawing usually shows the wiring state of the wire harness indicated by the design instruction diagram, the standing position of the jig necessary for the wiring, etc. in the actual size, and also includes the tape winding or the like. The procedure of the required operation to be applied to the laid electric wire is described.
