Description

  The present invention relates to a method and an apparatus for manufacturing a wire harness.

  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. Furthermore, since a wire harness often uses various connectors, there is a risk of connecting incorrectly.

  Then, the objective of this invention is providing the manufacturing method and manufacturing apparatus of a wire harness with few operation errors including the connection mistake of a connector.

  The present invention is a method of manufacturing a wire harness in which image data corresponding to an assembly process of a wire harness is switched and displayed on a display unit according to the progress of the assembly process in order to solve the above problems. The harness is a plurality of wire harnesses in which connectors are respectively connected to both ends of a plurality of electric wires, and the image data in the connecting step of the connectors provides a wire harness manufacturing method including a connector image representing the connectors.

  Further, in order to solve the above problems, the present invention is based on a display unit for displaying an image, a storage unit for storing image data corresponding to an assembly process of a wire harness, and the image data stored by the storage unit. And a control unit that controls the display unit to switch and display an image according to the progress of the assembly process, and the wire harness is a plurality of wire harnesses in which connectors are connected to both ends of a plurality of electric wires. The present invention provides a wire harness manufacturing apparatus, wherein the image data in the connecting step of the connector includes a connector image representing the connector.

According to the second embodiment, similar to the first embodiment, the functions and effects of the above (a) to (d) can be exhibited, and image data can be edited. In addition, the display unit can be miniaturized as compared with the first embodiment.

  Note that temporary drawing data corresponding to the assembly process may be used instead of the image data corresponding to the assembly process of the second embodiment. When the operator inputs the editing information of the temporary drawing using the touch pen, the electronic pen, etc. while keeping the wire harness along the image displayed on the touch panel display 12, the editing means of the managing device 6 is edited The temporary drawing data stored in the storage unit is edited based on the information. Here, "temporary drawing data" refers to one that includes drawing information indicating the wiring position of the wire harness and character information that instructs the harness assembling operation.

Third Embodiment
FIG. 10 is a cross-sectional view showing a schematic configuration example of a wire harness manufacturing apparatus according to a third embodiment of the present invention. In the second embodiment, one touch panel display 12 and one remote control 7 are connected to one management device 6, but in the present embodiment, a plurality of touch panel displays 12 and one remote control may be connected to one management device 6. 7 is connected directly or through a network such as the Internet.

According to the present embodiment, the following actions and effects can be obtained.
(A) The same wire harness assembly or different wire harness assemblies can be made simultaneously for multiple workers.
(B) Since the management apparatus 6 knows the start time and the end time of each process for each worker, it can grasp which worker is behind, and the number of people at the worker who is behind the worker You can increase and support.

  A plurality of touch panel displays 12 may be arranged side by side, and an image for one wire harness assembly may be divided and displayed on the plurality of touch panel displays 12. In this case, it is preferable that there is no gap between the touch panel displays 12.

[Other modification]
The embodiments of the present invention are not limited to the above-described embodiments, and various embodiments are possible without departing from the scope of the present invention. In each of the above-described embodiments, the wiring process of the harness 1, the wiring process of the harness 2, and the cloth process of the harness 3 each switch the image, but all the harnesses are displayed with their brightness reduced. Highlighting such as highlight display may be performed so that a portion related to the harness is highlighted such as displaying only a portion related to the harness brightly.

  Moreover, some of the components of the embodiment of the present invention may be omitted without departing from the scope of the present invention. For example, the image may be switched from the management device 6 without using the remote controller 7. In addition, in the first embodiment, the projection image may be projected directly on the screen without passing through a mirror.

  Further, within the scope not changing the gist of the present invention, addition, deletion, change, replacement and the like of processes are possible in the assembling process of the above embodiment.

Industrial application field

  The present invention is applicable to a harness for a railway vehicle, a harness for a car, a medical harness, an in-apparatus harness, and the like.
