Definitions

  • the invention relates to a method for inspecting a wire harness.
  • a wire laying board is used for assembling a wire harness.
  • the wire laying board is formed by sticking a full-size drawing of a wire harness onto an assembly drawing board and a wire laying jig is attached to the wire laying board.
  • operating instructions such as assembly procedure and accessory component attachment instructions are also given.
  • a worker lays an electric wire in accordance with the operating instructions and attaches accessory components to predetermined positions on the laid wire or a bundle of wires, thereby assembling a wire harness.
  • This drawing board device for assembling wire harness is provided with a wire laying board to which various jigs required to assemble a wire harness can be attached, an assembly jig attached to the wire laying board to hold an electric wire to be laid, and a display means for displaying images of wire harness assembling process on the wire laying board so that the images can be seen on the front surface of the wire laying board.
  • the images of the wire harness assembling process are switched according to three steps: a wire laying step, an accessory component attaching step and a tape winding step.
  • the conventional drawing board device for assembling wire harness is not configured that the image of the wire harness assembling process is changed to follow the work progress during the wire laying step. Therefore, when handling electric wires having similar lengths, a wrong wire may be laid or a wire may be laid on a wrong position. In addition, since the attachment position of the assembly jig is not included in the image of the assembling process, the assembly jig may be attached to a wrong position. Furthermore, in case that the assembly jig is configured to be attached to the wire laying board by being inserted through a hole formed on the wire laying board, there is a risk of damaging or breaking the wire laying board or the assembly jig and the attachment work is thus not easy. In addition, in general, an inspector carries out a wire harnesses inspection while reading wire harness work instructions. Thus, it is desired to reduce inspection time and to improve inspection reliability.
