BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire assembly line.

[0002]

2. Description of the Related Art Generally, a wire harness and a subassembly constituting the wire harness (hereinafter referred to as "wire assembly")
The wire is measured and cut, and the cut wire is laid in a predetermined form, and a connector is connected to the laid wire to form a circuit or taping is performed. This is an electrical wiring system that is assembled by attaching exterior parts such as corrugated tubes and clamps. In order to improve the efficiency of such an assembly process,
2. Description of the Related Art Conventionally, a wire assembly has been provided with a plurality of conveyors called an assembly drawing board and circulated by a conveyor, thereby performing various processes in a flow operation. The above-mentioned assembly board has a large number of U-shaped or ding-shaped holders, positioning members, and the like densely arranged for laying a measuring wire.

[0003] Here, the wire assembly is an electric wiring system in which a circuit is composed of electric wires and connectors. In the assembling process, it is necessary to strictly check for erroneous connection or poor conduction of each electric wire. Therefore, conventionally, a visual inspection device for conducting visual inspection of a wire assembly and an inspection table provided with a conduction unit connectable to a connector are provided, and the conduction state of the wire assembly is inspected with this inspection table to check for a contact failure or wiring. Had inspected for differences.

[0004]

In the continuity test as described above, it is preferable to incorporate a continuity test system into an assembly line for assembling a wire assembly and to make the continuity test inline in order to increase production efficiency. However, it is physically difficult to assemble the continuity inspection system because a large number of holders and members are densely arranged on the assembly board of the wire assembly. Even if the assembly can be performed, the continuity inspection system hinders the assembling of the wire assembly, and the work cannot be performed smoothly. In addition, when the continuity inspection system is provided on an assembly drawing board, it is necessary to provide the same system for each assembly drawing board orbited by a conveyor, so that there is a problem that equipment costs increase.

Therefore, conventionally, the continuity inspection process is performed separately from the assembly line, so that the tact time of the continuity inspection process is not synchronized with the tact time of the assembly line, resulting in poor production efficiency as a whole. The present invention has been made in view of the above-described problems, and has as its object to provide a wire assembly assembly line that can increase the efficiency of a wire assembly continuity inspection process and thereby improve production efficiency.
