Description

  The present invention relates to a wire harness manufacturing system and a wire harness manufacturing method.

  Generally, for assembly of a wire harness, a full-size drawing of the wire harness is attached to a drawing board for assembly to prepare a cloth wiring board, and a wiring wiring jig is attached to the wiring board. . The full scale drawing shows work instructions such as assembly work procedures and attachment instructions for accessories, and the operator lays the wires according to the work instructions, and is attached at a predetermined position of the laid wire or bundle of wires. Attach the parts and assemble the wire harness.

  However, since it is necessary to paste the full-size drawing in accordance with the design change, a drawing board device for wire harness assembly has been proposed which makes such work unnecessary (see, for example, Patent Document 1).

  The wiring harness assembling drawing board device includes a wiring board on which various jigs necessary for assembling the wire harness can be disposed, and an assembling jig attached to the wiring board and receiving the electric wire to be laid. And display means for displaying an image of an assembly process of the wire harness on the wiring board so as to be seen from the surface side of the wiring board.

  The image of the assembly process of the wire harness is switched in accordance with the three processes of the wire laying process of the electric wire, the attaching process of the accessory parts, and the tape winding process.

JP 2000-195352 A

  However, the conventional wiring board assembly drawing board device does not switch the image of the assembly process of the wire harness according to the work process in the wire laying process of the wire, and therefore, when laying out the wire whose length is similar In addition, there is a risk of mistaking the location of wires and wiring. In addition, since the mounting position of the assembly jig is not included in the image of the assembly process, the mounting position of the assembly jig may be incorrect. In addition, when attaching the assembly jig to the wiring board, if a hole is made in the wiring board and the assembly jig is inserted into the hole, there is a risk of damaging the wiring board or damaging the assembly jig. Yes, installation is not easy.

  On the other hand, mobile bodies such as railway cars and aircrafts are required to operate safely, and therefore, highly reliable wire harnesses are required. In addition, the automotive industry is also required to have high productivity that can quickly respond to shortening of the vehicle development period.

  Companies that manufacture wire harnesses independently manage the assembly order and branch positions of the wires, so even if they manufacture the same wire harness, the wire assembly order differs, resulting in the thickness and thickness of the bundled wires. The condition of twisting is different. This appears as misalignment of the end of the wire. In such a case, when connecting a connector to the both ends of an electric wire, the problem that a part of electric wires do not reach a connector arises. In order to avoid this, keep the electric wire long, cut the electric wire when connecting the connector and adjust the length, or adjust the short electric wire to connect the connector, and adjust to loosen the long electric wire. Occur. For this reason, the variation in thickness and length occurs between the wire harnesses, which may lead to a decrease in reliability.

  Then, the objective of this invention is providing the wire harness manufacturing system and wire harness manufacturing method which can manufacture a highly reliable wire harness with high productivity.

The control unit 60 reads projection image data corresponding to the wire harness identification information input to the input unit 62 from the storage unit 61 and transmits the projection image data to the projector 5.

  The control unit 57 of the projector 5 stores the projection image data transmitted from the management device 6 in the memory 58. The worker operates the ten key 72 of the remote controller 7 to input a worker ID for identifying the worker. Subsequently, the operator operates the start button 71a of the remote controller 7 to instruct the start of projection. The control unit 70 of the remote controller 7 transmits the worker ID to the management device 6 and transmits a start signal to the projector 5. The control unit 60 of the management device 6 stores the worker ID transmitted from the remote controller 7 in the storage unit 61 as the management data 612. The control unit 57 of the projector 5 starts the projection based on the start signal from the remote controller 7. That is, the control unit 57 reads the projection image data of the first page from the memory 58 and controls the projection unit 50 to project the projection image based on the projection image data of the first page on the screen 2.

In the laying process, specifications (type, color, length, etc. 9) of the electric wire are displayed in the projected image (the same applies to the following laying process).

  The operator confirms the “harness 1 wiring” of the process name 20a of the projected image 20 that is projected, selects a wire whose color is similar to that of the wire image 23a and has substantially the same length, and repairs the selected wire It arranges on electric wire picture 23a which passes between a pair of support pieces 130 of implement 10a.

  Next, connectors corresponding to the connector images 24a and 24b are connected to both ends of the wires. At this time, the worker confirms that the connector number added to the connector matches the connector number displayed in the connector images 24a and 24b, and then connects the connector. Specifically, the reading unit 73 of the remote controller 7 reads the bar code written in parallel with the connector numbers on the connector side and the connector images 24a and 24b. The determination unit 74 determines whether or not both match, and the determination result display unit 75 displays the determination result to notify the operator. Further, the control unit 70 of the remote controller 7 transmits the determination result to the management device 6 via the communication unit 76. The control unit 60 of the management device 6 receives the determination result via the communication unit 64, and stores the determination result together with the process name in the management data 612 as history information. Reading of the barcode, display of the determination result, and storage of the history information are similarly performed in the following wiring process of the harness.

  As described above, the wiring of the harness 1 ends. When the wiring of the harness 1 is finished, the operator operates the feed button 71b of the remote controller 7. The control unit 70 of the remote controller 7 transmits a page feed signal to the projector 5 based on the operation of the feed button 71 b.
