Description

  The present invention relates to an assembly drawing board apparatus for a wire harness and a wire harness assembly method used when assembling a wire harness used in a vehicle or the like.

  Generally, a drawing board used when assembling a wire harness of a vehicle or the like has a single flat plate structure, and the surface thereof is arranged along a wiring circuit for wiring an electric wire or a wiring circuit. A wiring jig such as a U-shaped jig for holding the electric wire to be bent and a clamp mounting jig for holding a clamp for binding the electric wires is provided.

  Then, the assembly worker lays out the electric wires along the wiring circuit of the board arranged in an inclined manner, binds the bundles of the wired wires, and attaches electric parts such as connectors to the electric wires. The wire harness was assembled by joining.

  Further, when assembling wire harnesses having different types of wire harness circuits, so-called product numbers, it is necessary to replace the drawing board. In such a case, in order to save the trouble of replacing the drawing board, the board to which the drawing board is attached has a polyhedron structure, and the drawing board with a different product number is arranged in advance on each of the surrounding surfaces to rotate the mounting board. There has also been proposed an assembly drawing board device for a wire harness in which a drawing having a target product number is brought to a work position (see, for example, Patent Document 1).

  By the way, in recent years, the number of circuits of the wire harness has increased with the increase of in-vehicle devices mounted on the vehicle, and has become complicated.

  On the other hand, the board for assembling the wire harness has a limit in the height direction which is the width direction from the viewpoint of workability, and is within a predetermined range (for example, 850 mm) that can be easily reached by an assembly worker. It has been.

  Therefore, the complexity of the wire harness circuit has been dealt with by extending in the length direction, which is the lateral direction, because the width direction of the drawing board is limited.

  However, there is a limit even in the range that can be handled by extending the drawing board in the length direction, and, for example, if more branch circuits from the main circuit are required within the limited drawing board width, As the density increases, the width between the branch circuits on the drawing board becomes narrower, the arrangement of the wiring jigs becomes dense, and it becomes difficult to develop the wiring path within the limited width of the drawing board. Come.

  And it was tilted when it was not needed using a folding clamp mounting jig, etc., but if the wiring density became such that the wiring jig could not tilt due to the complexity of the circuit, A line circuit cannot be constructed.

  Therefore, a partial harness part that is manufactured in advance in a separate process (partial completion process) as a partial harness part of a part of the circuit in such a wiring circuit and then assembled into the required part. The method of assembling was adopted.

  However, when a partial harness component is manufactured in a separate process, a separate drawing board for the partial harness component is required. There was a disadvantage that waste of overlapping wirings such as assembling harness parts occurred.

  Therefore, in view of the above-described problems, the present invention provides an assembly drawing board device for a wire harness and a wire harness assembly method that effectively reduce the density of the wiring jigs and prevent waste of overlapping wirings. The purpose is to do.
