[Problems to be solved by the invention]
When manufacturing large and medium-sized wire harnesses with a very large number of wires, post-processing, temporary bundling, assembly, and inspection are performed separately, and the assembly work is performed by the flow work using the equipment shown in FIG. The wire harness can be assembled well. However, when assembling a small wire harness with a small number of wires, there is a problem of inefficiency in capital investment.
[0004]
That is, in the conventional wire harness manufacturing apparatus, the post-processing apparatus, the assembly apparatus, and the inspection apparatus including the terminal crimping to the electric wire terminal are separate apparatuses, and the post-processing and temporary binding are performed in another factory. In many cases, assembly and inspection cannot be performed on a single drawing board. In particular, in the assembly process, the wire group is wired with a regular dimension, and in the post-processing process, it is very difficult or impossible to process the wire group that is wired in a regular dimension with a regular dimension. Therefore, the post-processing step and the assembly step could not be performed on the same drawing board.
[0005]
The present invention has been made in view of the above-described problems. The post-processing process, the assembly process, and the inspection process can be performed on a single drawing board to improve workability, and a wire harness can be easily manufactured. Therefore, it is an issue to be able to perform efficiently.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention divides a drawing board provided with a wiring jig upright into a plurality of numbers, and connects the divided drawing board in a telescopic manner via a connecting rod, and extends the maximum dimension position. On the other hand, the wire group that is routed through the wiring jig erected on the drawing board is set to have a normal length, while the drawing board is continuous or at a position where the interval is reduced, the wire group. Provides a wire harness manufacturing apparatus in which a jig, a processing machine, and a continuity inspection machine necessary for the post- processing are installed on a fixed base so that the wire terminal can be post-processed by being loosened. .
[0007]
As described above, the drawing board for manufacturing a wire harness is divided into a plurality of parts and connected to each other by a connecting rod so that the drawing board can be deformed according to the working state. While the post-processing and continuity inspection can be performed by loosening the group, by extending the drawing board to the maximum dimension after finishing the post-processing, the wires can be stretched to normal dimensions, and these wires can be bundled. Post-processing, assembly / inspection, and bundling can be performed on the drawing board, and work efficiency can be improved.
[0008]
A roller is attached to the lower part of the drawing board to form a drawing board carriage. On the other hand, a guide rail is laid on the fixed base, the roller is regulated on the guide rail, and the operator can run when pushed by an operator. Since the drawing board carriage is divided as described above, these divided carriages are each provided with a drawing board to which a roller is attached, and these drawing boards are connected to each other in a telescopic manner via the connecting rod as described above. .
[0009]
As shown above, when the operator moves the drawing cart by hand, the equipment becomes simpler than when the chain is driven by a conventional drive unit, and the wire harness is changed. The device side can also be changed correspondingly easily.
[0010]
A connector receiving jig and a wire terminal terminal receiving jig are projected on the above plate, and a terminal connected to the continuity test connector is projected on these jigs, and the connector and the wire terminal terminal fitted to these jigs are connected. While the terminal is fitted, the continuity test connector is fitted to the continuity tester and the continuity test is performed when the drawing cart is transported to the continuity tester installation position installed on the fixed base. It is said. At the time of this continuity test, the drawing board carriage is in a contracted state, and after the continuity inspection, the drawing board carriage is extended to a normal dimension.
[0011]
Thus, since the connector and the electric wire terminal terminal that require continuity inspection are configured to be connected to the continuity inspection connector in a state of being attached to the jig, the continuity inspection connector is arranged along the conveyance path of the drawing board carriage. If installed, it is not necessary to conduct the continuity inspection after the wire harness assembling work is completed as in the prior art, and it can be performed during the wire harness assembling process.
[0012]
The present invention further provides a method of manufacturing a wire harness using the above-described wire harness manufacturing apparatus, and in a state where a plurality of electric wires are cut to scale, the wires are routed through a wiring jig on a drawing board. And
Next, perform post-processing such as crimping of the terminal to the end of the wire, welding of the terminal core wire of the plurality of wires, tube passing work to the welded portion in the state where the wire is loosened on the above-mentioned drawing board,
Next, after conducting a terminal continuity test with a continuity tester, insert the terminal into the connector, etc.
After that, stretch the electric wire with the above-mentioned drawing plate as the maximum dimension position and make it a normal dimension, bind the electric wire group with tape winding etc.,
Provided is a method for manufacturing a wire harness in which post-processing, assembly and inspection are performed on a single drawing board.
[0013]
The manufacturing method described above can be suitably used for manufacturing a wire harness for a two-wheeled vehicle having a small number of electric wires and a large amount of post-processing.

The continuity test of the connectors and the wire terminal terminals held by the jigs 21 and 22 is performed at a time.
The electric wire terminal receiving jig 24 has a coil spring 24a attached to a support shaft 24b, and inserts and holds an electric wire between the coils of the coil spring 24a.
[0020]
Furthermore, the processing machine which consists of the welding machine 25 is installed in the required position of the fixed base 10 with which the board carriage 12 travels, and it is mounted in the terminal crimping machine 26 which an operator manually pressures in a required location. Moreover, the above-described continuity tester 27 is also installed.
[0021]
The fixed base 10 has a rectangular shape as shown in FIG. 1, and a guide rail 11 is laid endlessly thereon. One end on the short side of the fixed base 10 is a work start position, and from this position in accordance with the conveying direction of the drawing cart 12, the electric wire setting process → the electric wire setting / part passing process → the electric wire setting / part passing / crimping process → A part threading process → welding / part threading process → welding process → rubber plug threading / crimping process → part threading / crimping / common crimping process → terminal insertion process is performed on one side of the long side of the fixing base 10. Next, the board carriage 12 rotates on the fixed base 10 and on the other side of the long side, the terminal insertion / conduction setting process → first binding process → second binding process → third binding process → first binding / parts An attaching process → second binding / part attaching process → an appearance inspection process is performed. The worker P waits at the position of each process and performs a required process. After the completion, the drawing carriage 12 is pushed by hand to the next process.
[0022]
The terminal crimping machine 26 and the welding machine 25 are disposed on the fixed base 10 at a position where the crimping process and the welding process are performed. Further, the continuity tester 27 is disposed at a position where the continuity test process is performed. Furthermore, a holder 29 (not shown) for a required part such as a terminal, a cap and the like to be attached to the electric wire, a rubber plug, a tape, a clamp, etc. is installed on the fixed base 10 or a peripheral base and waits at each process position. The worker who is doing so can easily take out the required parts.
[0023]
Next, the manufacturing process of the wire harness comprising the above apparatus will be described.
The electric wire group constituting the wire harness is brought into the manufacturing apparatus shown in FIG. 1 in a state of being cut and cut, and the electric wire terminal is carried out according to the above-described process on the one drawing carriage 12 that conveys the fixed base 10. Post-processing, bundling and inspection are sequentially performed.
[0024]
First, from the wire setting process to the terminal insertion / conduction setting process, the three carriages 12A, 12B, and 12C of the drawing board carriage 12 have a length of the minimum dimension L1 as a continuous state. In this state, first, in the electric wire setting step, wiring is performed through the electric wire w on the wiring jig 20 on the drawings 13A to 13C. At this time, as shown in FIG. 3 (A), the drawing boards 13A to 13C are continuous and have a minimum dimension, and therefore the electric wire w is wired in a slack state. When this electric wire setting process is completed, the worker pushes the drawing carriage 12 by hand to move to the next electric wire setting / part passing process. Thereafter, in a post-processing step from the component setting / component passing step to the terminal crimping, necessary components such as a tube and a waterproof rubber plug are attached to the wire in order, and the crimping machine 26, In the welding machine 25, common crimping and terminal intensive welding of the terminal to the core wire previously exposed from the electric wire are performed. For example, as shown in FIG. 4B, the core wires exposed from the ends of the plurality of electric wires are concentratedly welded by the welding machine 25, and then the tube 30 is put on the concentrated welded portion and held by the jig 22. I am letting.
[0025]
After the necessary post-processing steps such as crimping of the terminal to the electric wire end are completed as described above, the connector is fitted to the connector receiving jig 21. At that time, a terminal T for continuity inspection is inserted into the cavity of the connector and is fitted with the terminal in the connector.
[0026]
As shown in FIG. 1, until the end of the continuity test, the electric wire w is doubled with the carriages 12A, 12B, and 12C set to the minimum dimension L1, so that the post-processing of the electric wire tip can be performed without difficulty. In the continuity process, the continuity test connector 23 is fitted with the continuity tester 27 to conduct the continuity test.
[0027]
After the continuity test is completed, as shown in FIG. 3B, the carriages 12A, 12B, and 12C are expanded to the width of the maximum dimension L2, and the assembly dimensions of the regular wire harness are obtained. In this state, the first binding step → second binding step → third binding step → first binding / part attaching step → second binding / part attaching step is performed. Finally, a visual inspection is performed to manufacture a wire harness.
[0028]
As described above, the figure carriage 12 can be divided to narrow or widen the figure, so that the electric wire can be doubled on the figure for post-processing, and the electric wire is straight. The wire group can be bundled as a regular assembly dimension extended into a shape.
[0029]
In addition, this invention is not limited to the said embodiment, You may construct | lay a guide rail on a fixed stand in linear form, without making it an elliptical endless shape. Moreover, it is not always necessary to restrict and convey the guide rail, and it may be possible to freely move to any place on the fixed base.
[0030]
Further, in the above embodiment, only the cutting of the electric wire is performed in advance, and all the post-processing including the connection of the terminal to the electric wire terminal is performed on the drawing board carriage, but the crimping of the terminal to the electric wire terminal, Although connection of these terminals to the connector may be performed in advance, it is preferable to perform post-processing as much as possible on the drawing board carriage.
[0031]
【The invention's effect】
As is clear from the above description, according to the present invention, the divided figure boards can be slid and moved apart and changed in size according to the work state required in each process, so that the dimensions can be changed. Can be post-processed by loosening the wire to loosen the electric wire, and extending between the drawing plates to extend the electric wire to a normal dimension, and the electric wire group can be bound by tape winding or the like. In this way, the post-processing, inspection, and assembly steps of the electric wire can be performed on one drawing board, so that the work efficiency is dramatically increased compared to the case where each step is performed with a conventional separate device. be able to.
[0032]
In addition, since a roller is attached to the lower part of the drawing board to move it when the operator pushes it, the equipment is simple compared to the case where the drawing board is mounted on a chain driven by a conventional driving device. Therefore, even when the wire harness to be manufactured is changed, the equipment can be changed easily and inexpensively.
