Description

  The present invention relates to a method for manufacturing a wire harness, a manufacturing system, and a management apparatus.

  For the assembly of the wire harness, generally, a wiring board is prepared by pasting the full size diagram of the wire harness on the assembly board, and a wiring board is attached to the wiring board. . The full-scale drawing shows work instructions such as assembly work procedures and attachment instructions, etc., and the operator lays the wires according to the work instructions and attaches them to the predetermined positions of the wired wires and bundles of wires. Attach the parts and assemble the wire harness.

  However, since it is necessary to paste the original drawing according to the design change, a wire harness assembling board device that eliminates such work has been proposed (for example, see Patent Document 1).

  This wire harness assembling drawing board device includes a wiring board on which various jigs necessary for assembling the wire harness can be disposed, an assembly jig that is attached to the wiring board and receives the wired wires, Display means for displaying an image of the assembly process of the wire harness on the wiring board so as to be visible from the surface side of the wiring board.

  The image of the assembly process of the wire harness is switched according to the three processes of the wiring process of the electric wire, the attachment process of the accessory parts, and the tape winding process.

JP 2000-195352 A

  However, the conventional wire harness assembly drawing board device does not switch the image of the assembly process of the wire harness according to the work process in the wiring process of the electrical wire. In addition, there is a risk of mistakes in the location of wires and wiring. Further, since the mounting position of the assembly jig is not included in the image of the assembly process, there is a possibility that the mounting position of the assembly jig is erroneous. Also, 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, the wiring board may be damaged or the assembly jig may be damaged. Yes, installation work is not easy.

  On the other hand, since mobile bodies, such as a railway vehicle and an aircraft, need to operate | move safely, a highly reliable wire harness is calculated | required. In the automobile industry, high productivity that can quickly respond to shortening of the vehicle development period is also required.

  Since companies that manufacture wire harnesses independently manage the assembly order and branching position of the wires, even if the same wire harness is manufactured, the assembly order of the wires is different, resulting in the thickness and Twisting is different. This appears as a 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 wire does not reach a connector arises. To avoid this, adjust the length of the wires so that they can be adjusted by cutting the wires when connecting the connectors, or by connecting the connectors to the short wires and loosening the longer wires. Occur. For this reason, variations in thickness and length occur between the wire harnesses, which may lead to a decrease in reliability.

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

[Other variations]
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 said embodiment, although the wiring process of the harness 1, the wiring process of the harness 2, and the wiring process of the harness 3 each switched the image, all the harnesses were displayed by reducing brightness, the said Highlighting such as highlighting may be performed so that only the portion related to the harness is displayed brightly, such as the portion related to the harness is conspicuous.

  Moreover, you may omit a part of component of embodiment of this invention in the range which does not deviate from the summary of this invention. For example, images may be switched from the management device 6 without using the remote controller 7. In the first embodiment, the projected image may be directly projected on the screen without using a mirror. Furthermore, the projected image may be projected on a screen via a plurality of mirrors. Thereby, thickness reduction can be achieved.

  In the above embodiment, the editing information is provided to the server apparatus 200 via the network 300. However, the editing information may be provided to the server apparatus 200 via a recording medium such as a USB memory or a CD-ROM.

  Moreover, you may add the order information by the number etc. which show an assembly order to an electric wire.

  Moreover, in the said embodiment, although the authentication process was performed by the server apparatus 200 side, authentication information is hold | maintained at the wire harness manufacturing apparatus 1 side, for example, the control part 60 of the management apparatus 6, or the control part 60 or the management apparatus 6 side. The control unit 70 of the remote controller 7 may perform authentication processing.

  In the above embodiment, the person to be authenticated is described as an administrator, but it may be an operator. Alternatively, the administrator may be omitted and the operator may perform the administrator's work.

  In the said embodiment, although the wire harness manufacturing apparatus 1 was demonstrated as having a hard disk, you may not have a hard disk. The wire harness manufacturing apparatus in this case displays the screen data presented from the server apparatus 200 on the display unit for each page and browses the screen data. By not providing the wire harness manufacturing apparatus with a hard disk, information leakage due to outflow of image data can be prevented.

  In addition, within the scope of the present invention, it is possible to add, delete, change, and replace processes in the assembly process according to the above embodiment.

  In addition, the constituent elements of the respective embodiments can be arbitrarily combined within the scope not changing the gist of the present invention. For example, in the second and third embodiments, the touch panel display 12 is used as means for inputting editing information and the like. However, a pointing light like an interactive pen is used with respect to the screen 2 of the first embodiment. A pointing device that irradiates (for example, infrared rays or laser light) and detects the coordinates of the irradiation point with a camera can be used. Also, editing information or the like may be input by detecting the position of the electronic pen on the screen 2 with respect to the screen 2 of the first embodiment. As such a method, an ultrasonic type (the sensor receives the ultrasonic wave transmitted by the electronic pen), an infrared type (the sensor receives the infrared ray output from the electronic pen), a camera type (for specifying the coordinates of the electronic pen) A translucent sheet on which a special pattern is thinly printed) can be used.
