Field of the Invention The present invention relates to a wire harness manufacturing apparatus and manufacturing method, and a wire harness manufacturing apparatus for manufacturing a wire harness with a connector by inserting a terminal of an electric wire with a terminal into a terminal accommodating chamber of a connector housing and It relates to a manufacturing method.

  2. Description of the Related Art Conventionally, electronic devices mounted on a vehicle such as an automobile are connected via a wire harness in order to transmit and receive electric power and control signals to each other. The wire harness includes a plurality of terminals-attached electric wires in which terminal fittings are crimped to the ends of the electric wires, and a connector having a connector housing that houses the terminal fittings of the plurality of terminal-attached electric wires. These connectors are fitted and connected to connectors of electronic devices and connectors of other wire harnesses.

  Such a wire harness is generally manufactured through steps such as manufacture of an electric wire with a terminal, manufacture of a connector housing, fitting of a terminal to the connector housing, wiring of a sub-harness, and attachment of an exterior product. Hereinafter, with reference to FIG.7 and FIG.8, the manufacturing method of a general wire harness is demonstrated.

  First, as shown in FIG. 7A, as a procedure for manufacturing the terminal-attached electric wire 10 constituting the wire harness W1, an electric wire W provided with an insulating coating is prepared, and the electric wire W is cut to a predetermined length. The The insulation coating on both ends of the electric wire W is peeled off, and the terminal fitting 11 is crimped to the exposed core wire of the electric wire W.

  Moreover, the intermediate insulation coating of the electric wire W is peeled off, and another electric wire with one terminal is branched and connected by the joint terminal 11A to produce the electric wire 10 with a terminal. A plurality of types of such electric wires with terminals 10 are manufactured in accordance with the length of the electric wires W and the shapes of the terminal fittings 11, and are stored separately in electric wire supply shelves.

Next, as shown in FIG. 7B, the terminal-attached electric wire 10 to be used is selected from the electric wire storage shelf, the electric wire with terminal 10 is combined in units of connectors 12, and the terminal fitting 11 is connected to the terminal housing chamber of the connector housing. The sub-harness W2 is manufactured by inserting into the terminal 21 (terminal fitting).
Instead of attaching the terminal fitting 11 to the connector housing 20, the terminal fitting 11 is held between the terminal holder clamps in an exposed state, and another sub-harness is provided on the wiring board for manufacturing the wire harness W1. You may perform what is called a back fitting with which a connector housing is mounted | worn.

  Next, as shown in FIG. 8, a plurality of sub-harnesses W2 are locked and wired on the wiring board 13 by a plurality of fork-shaped locking pins 14, and a unit of a connector 12 or a unit of a terminal holder A plurality of sub-harnesses W2 manufactured by combining the two are arranged two-dimensionally so as to substantially conform to the actual wiring form in the vehicle, and the wire harness W1 is manufactured. Moreover, the terminal metal fitting 11 clamped by the clamp of the terminal holder is retrofitted to the connector housing to be attached. The routed sub-harness W2 is temporarily fixed at appropriate places with the tape 17, and the tape is wound and converged over the whole from above to form the wire harness W1. Exterior parts such as a protector 15 and a waterproof grommet 16 are attached to the wire harness W1 as necessary.

  Conventionally, when manufacturing each sub-harness W2, there is a method of manufacturing a wire harness that guides the terminal fitting 11 into the terminal accommodating chamber 21 to be inserted so that the terminal fitting 11 is not mounted in the wrong terminal accommodating chamber 21 of the connector housing. It has been proposed (see, for example, Patent Document 1).

  As shown in FIG. 8, the method for manufacturing a wire harness described in Patent Document 1 performs a continuity test when a terminal fitting for inserting the terminal fitting 11 of the electric wire with terminal 10 into the connector housing 20 is performed. The connector housing 20 is attached to the terminal insertion guiding device 85.

  The terminal insertion guiding device 85 includes an LED display unit 34 corresponding to the arrangement of the terminal accommodating chambers 21 of the connector housing 20. The terminal insertion guiding device 85 displays the terminal accommodating chamber 21 to be fitted with the terminal fitting 11 of the electric wire 10 with a terminal to be next attached to the connector housing 20 by the LED display unit 34. And whenever each terminal metal fitting 11 fits in the terminal storage chamber 21, the conduction | electrical_connection test | inspection of the electric wire 10 with a terminal is performed. Thereby, the continuity inspection of the electric wire 10 with a terminal is performed every time each terminal fitting 11 is inserted, and the presence or absence of miswiring, the disconnection of the electric wire W, the crimping failure of the terminal fitting 11 or the like is checked.

  Thus, conventionally, in the manufacturing process of the sub-harness W2, the operator can attach the terminal by displaying the terminal accommodating chamber 21 of the connector housing 20 to which the terminal-equipped electric wire 10 is to be fitted next by the LED display unit 34. The terminal accommodating chamber 21 into which the electric wire 10 should be inserted can be confirmed and work can be performed.

However, although this conventional method for manufacturing a wire harness can be used for manufacturing the sub-harness W2, there is a problem that it is difficult to use in the process of manufacturing the wire harness W1 by collecting a plurality of sub-harnesses W2. .
That is, when the sub-harness W2 is manufactured, a specific electric wire can be selected by induction, and the selected electric wire can be guided to the terminal accommodating chamber 21 of the connector housing 20 or the clamp of the terminal holder, but the wire harness W1. Since the sub-harness W2 is arranged on the wiring board in accordance with the actual wiring form, there is a problem that it is difficult to discriminate each electric wire by conduction.

  Therefore, even when the terminal fitting 11 is clamped by the correct clamp of the terminal holder when the sub-harness W2 is manufactured, the worker selects the wrong terminal-attached electric wire 10 from the terminal holder when the wire harness W1 is manufactured. There is a possibility that it will be fitted into the connector housing of the sub-harness W2.

Note that the terminal holder 55 may include a limit switch for detecting that the clamp 59 is holding the electric wire instead of including the photosensor 63. In this case, an opening for guiding the electric wire connected to the limit switch to the electric wire insertion hole of the holder main body 56 is formed in the flange portion 57.
The collar portion 57 is not limited to the above-described configuration, and extends to a position including the holder-side light emitting portion 61 so that the clamp 59 and the holder-side light emitting portion 61 can be attached to and detached from the holder body 56 integrally. May be.

  As shown in FIG. 4, the terminal fitting device 30 and the terminal holder 55 configured as described above are arranged at positions close to each other at the time of rear fitting, and the operator turns on the holder side light emitting unit 61 and the connector side light emitting unit 81. The terminal-equipped electric wire 10 sandwiched between the terminal holders 55 is inserted into the terminal accommodating chamber 21 while confirming the above.

  As shown in FIG. 5, the guidance control unit 50 includes a CPU 71, an operation unit 72 for inputting various data and operation signals, a memory I / F 73 to which a storage medium storing data can be attached and detached, Data storage unit 74, I / F 76 for transmitting and receiving signals between the holder side light emitting unit 61 and the photosensor 63 of the terminal holder 55, the connector side light emitting unit 81 of the main body unit 31 and connection detection An I / F 77 for transmitting and receiving signals to and from the unit 33.

The operation unit 72 is provided with a switch and a key for accepting an operator's operation for starting and ending guidance control by the terminal fitting guidance device 5.
The storage unit 74 is configured by a rewritable nonvolatile memory. The storage unit 74 includes a program necessary for performing the guidance operation by the terminal fitting guidance device 5, the order of the terminal-attached electric wires 10 to be terminal-fitted in the molding station 1, and the connector housing 20 to be inserted. Operation sequence data in which the position of the terminal accommodating chamber 21 is associated is stored.

  The operation order data is stored in advance in a storage medium constituted by a memory card or the like, and is stored in the storage unit 74 via the memory I / F 73 from the storage medium. The operator inputs the order of the terminal-attached electric wires 10 to be terminal-fitted by the operation unit 72 and the position of the terminal accommodating chamber 21 of the connector housing 20 to be inserted, and creates operation order data. May be.

  Alternatively, the terminal fitting guidance device 5 may automatically recognize a product signboard or a work instruction bar code, and execute a program that matches the product based on the recognized result.

Next, the operation of guidance control by the terminal fitting guidance device 5 will be described with reference to FIG.
When the operator operates the start switch of the operation unit 72, the terminal fitting guidance device 5 enters a state of waiting for selection of operation order data used for guidance control. Here, the operator can use the operation unit 72 to select whether to use the operation sequence data already stored in the storage unit 74 or to newly input the operation sequence data. When the operation order data is newly input, when the operator inserts the storage medium storing the operation order data into the memory I / F 73, the CPU 71 of the terminal fitting guidance device 5 stores the operation order data in the storage medium. Is stored in the storage unit 74.

  Then, the CPU 71 reads the operation sequence data (S1), and first lights the holder side light emitting unit 61 representing the clamp 59 in which the terminal-attached electric wire 10 to be inserted into the terminal accommodating chamber 21 of the connector housing 20 is sandwiched. (S2). At this time, a signal indicating that the terminal-attached electric wire 10 is held between the clamps 59 is input to the CPU 71.

  When the operator removes the terminal-attached electric wire 10 from the clamp 59 (Yes in S3), the CPU 71 receives a signal indicating that the terminal-attached electric wire 10 is not held by the clamp 59 from the photosensor 63.

  Here, the CPU 71 receives a signal indicating that the terminal-attached electric wire 10 is not sandwiched from the photo sensor 63 corresponding to the clamp 59 different from the clamp 59 corresponding to the holder-side light emitting unit 61 that is lit. (No in S3), the lighting of the holder side light emitting unit 61 that is currently lit is continued. On the other hand, when a signal indicating that the terminal-attached electric wire 10 is not sandwiched is input from the photosensor 63 corresponding to the clamp 59 corresponding to the lit holder-side light emitting unit 61, the CPU 71 is lit. The holder side light emitting unit 61 is turned off (S4), and the connector side light emitting unit 81 at a position corresponding to the terminal accommodating chamber 21 of the connector housing 20 into which the terminal-attached electric wire 10 removed from the clamp 59 is to be inserted is turned on. (S5).

  Subsequently, when the operator inserts the terminal-attached electric wire 10 into the terminal accommodating chamber 21 corresponding to the lit connector-side light emitting unit 81 (Yes in S6), the CPU 71 causes the connector housing 20 to store the terminal. A signal indicating that the terminal-attached electric wire 10 has been inserted is input from the connection detection unit 33 corresponding to the chamber 21. In this case, the CPU 71 determines that the first terminal-attached electric wire 10 has been inserted into the correct terminal accommodating chamber 21 of the connector housing 20, and turns off the lit connector-side light emitting unit 81 (S7).

  On the other hand, when a signal indicating that the terminal-attached electric wire 10 has been inserted is input from the continuity detection unit other than the connection detection unit 33 corresponding to the terminal storage chamber 21 (No in S6), the CPU 71 currently The lighting of the lit connector side light emitting unit 81 is continued.

  When the CPU 71 determines that the first terminal-attached electric wire 10 has been inserted into the correct terminal accommodating chamber 21 of the connector housing 20, the CPU 71 refers to the operation sequence data, and then the terminal-attached electric wire 10 to be inserted into the connector housing 20. Whether or not remains is determined (S8). If it does not remain (No in S8), the guidance control is terminated. When remaining, the holder side light emission part 61 corresponding to the clamp 59 in which the electric wire with terminal 10 to be inserted next into the connector housing 20 is clamped is turned on (Yes in S8).

  By performing such guidance control, the terminal fitting guidance device 5 should indicate the position of the terminal-attached electric wire 10 to be handled by the operator by lighting the holder-side light emitting unit 61 and insert the terminal-attached electric wire 10. Since the terminal housing chamber 21 of the connector housing 20 is indicated by the connector-side light emitting portion 81, it is possible to prevent the operator from selecting the wrong terminal-attached electric wire 10 or inserting it into the wrong terminal housing chamber 21. In particular, the terminal fitting guidance device 5 can give an appropriate guidance to the operator in the back fitting that is difficult to induce by conduction.

  In addition, when the operator removes the wrong terminal-attached electric wire 10 from the clamp 59, the terminal fitting guiding device 5 does not turn on the connector-side light-emitting portion 81. Insertion into the housing 20 can be prevented. At this time, since the terminal fitting guiding device 5 continues to light the holder-side light emitting unit 61 corresponding to the position of the terminal-attached electric wire 10 that should be selected by the operator, the operator can return to the correct work order. .

  Further, the terminal fitting guiding device 5 is a holder that shows the terminal-equipped electric wire 10 to be selected next when the operator selects the correct electric wire 10 with the terminal, but is inserted into the wrong terminal accommodating chamber 21. Since the side light emitting unit 61 is not turned on, the operator can recognize that the insertion operation performed immediately before is incorrect.

  In the above description, the case where the connector side light emitting portion 81 is installed in the vicinity of the terminal accommodating chamber 21 of the connector housing 20 has been described as an example. It may be installed inside the terminal accommodating chamber 21. In this case, when the connector-side light emitting unit 81 has a switch pin and the terminal-side electric wire 10 is inserted while the connector-side light emitting unit 81 is lit, the connector-side light emitting unit 81 is turned off. Further, by adjusting the position of the bottom dead center of the switch pin so that the connector-side light-emitting portion 81 is turned off when the terminal-attached electric wire 10 is completely inserted rather than incompletely inserted, the terminal as previously performed After the attached electric wire is fitted into the terminal accommodating chamber, it is possible to omit the step of pulling the electric wire with the terminal and checking for incomplete insertion or play. Moreover, since the connector side light emission part 81 lights in the terminal accommodating chamber 21, discrimination | determination of the terminal accommodating chamber 21 which should insert the electric wire 10 with a terminal becomes easier to understand.

  Moreover, in the above description, the case where the wiring board 13 was used as the forming station 1 was described. However, instead of the wiring board 13, as shown in FIG. 9, a metal support member 88 extends from the metal frame frame 89 only to a place where a jig such as the locking pin 14 is installed. The wire harness W1 may be formed using the bone jig 87.

  The molding station 1 using the bone jig 87 includes a bone jig 87 and a movable support base 92 as a module movable in the vertical direction indicated by an arrow S in the figure with respect to the bone jig 87. Yes. The locking pin 14 and the component holding jig 90 are supported on the support member 88 of the bone jig 87, and the operator first puts the movable support base 92 on the component holding jig 90 in a state where the movable support base 92 is lowered. The wire harness W1 is assembled using the held parts. At this time, the operator can easily insert his / her hand also under the wire harness W <b> 1, and the operation becomes easier as compared with the case where the wiring board 13 is used. When the predetermined assembly process is completed, the movable support base 92 that supports the additional component holding jig 91 is raised to the vicinity of the bone jig 87. The worker continues assembling the wire harness W <b> 1 using the components held by the additional component holding jig 91.

In such a molding station 1, for example, the terminal holder 55 and the connector holder 32 are supported by a movable support base 92. On the other hand, among the component holding jigs 90 supported by the bone jig 87, when the movable support base 92 is raised, the terminal holder 55 and the connector holder 32 are arranged in the vicinity. Is held.
Then, when the movable support base 92 rises, for example, the operator routes the terminal portion of the sub-harness provided with the terminal fitted to the connector housing 20 to the terminal holder 55 in a state where the clamp 59 holds the terminal portion. Next, the connector housing 20 held by the component holding jig 90 is fitted into the connector holder 32 supported by the movable support base 92. Then, the terminals temporarily held by the terminal holder 55 are sequentially inserted into the connector housing 20 according to the same procedure as described above.

  Alternatively, when the movable support base 92 is lifted, for example, the operator routes the terminal portion of the sub-harness provided with the terminal fitted to the connector housing 20 to the terminal holder 55 in a state where the clamp 59 holds the terminal portion. Next, the connector housing 20 of another sub-harness provided with the connector housing 20 is fitted into the connector holder 32. Then, the terminals temporarily held by the terminal holder 55 are sequentially inserted into the connector housing 20 according to the same procedure as described above. Then, the connector housing 20 is held by the component holding jig 90 close to the connector holder 32 after the insertion work is completed.

By using such a molding station 1, the operator can easily perform a series of operations including rear fitting by moving the movable support base up and down as necessary.
