Specific embodiments of the present invention will be described below with reference to each figure.

FIG. 1 is a schematic configuration diagram of a wiring device according to this embodiment.

As shown in FIG. 1, the wiring device 100 according to the present embodiment includes a jig plate 11, a plurality of jigs 12, a wiring arm 13, a processing arm 14, and a jig arm 15. , and a control section 16. This wiring device 100 is a device for wiring a wire harness 1 to a jig plate 11. In this example, the wire harness 1 includes a first electric wire 2A and a second electric wire 2B. A first connector 3A is connected to one end of the first electric wire 2A and the second electric wire 2B, a second connector 3B is connected to the other end of the first electric wire 2A, and a second connector 3B is connected to the other end of the first electric wire 2A. A third connector 3C is connected to the other end.

The jig plate 11 is composed of a plurality of sub jig plates 21. These sub-jig plates 21 are supported in a line by a pair of rails 22, and are slidable. A slide drive section 23 is provided on one side of the jig plate 11. The slide drive section 23 includes a support rail 24 and a moving section 25 supported by the support rail 24. The moving part 25 is fixed to one side edge of each sub-jig plate 21. The moving part 25 moves in the longitudinal direction with respect to the support rail 24. When this moving part 25 moves along the support rail 24, the sub-jig plate 21 supported by the rail 22 slides. In the jig plate 11, by sliding the sub jig plates 21, the sub jig plates 21 come close to each other or move away from each other.

The plurality of jigs 12 are erected on the upper surface of the sub-jig plate 21 that constitutes the jig plate 11. The jig 12 includes, for example, a magnet, and is attracted to the upper surface of the sub-jig plate 21 by the magnetic force of the magnet and is erected. The jig 12 includes a connector jig 31 and a wire jig 32. The connector jig 31 has a box-shaped connector holding part 31a on its upper part, and the connectors 3A to 3C are held in this connector holding part 31a. The electric wire jig 32 has a U-shaped electric wire holding part 32a on its upper part, and the electric wires 2A and 2B are locked and held in this electric wire holding part 32a.

The wiring arm 13, the processing arm 14, and the jig arm 15 are all actuators such as robots. For example, the wiring arm 13, the processing arm 14, and the jig arm 15 are multi-jointed robots, and each has robot hands 13a, 14a, and 15a at their tips.

The wiring arm 13 uses a robot hand 13a to grasp the electric wires 2A, 2B and connectors 3A to 3C of the wire harness 1, and holds them in a jig 12 erected on the jig plate 11. For example, the processing arm 14 performs processing such as tape wrapping on the wire harness 1 using the robot hand 14a. The jig arm 15 grips and moves the jig 12 using the robot hand 15a, and places it on the jig plate 11.

The control unit 16 controls the driving of the slide drive unit 23 of the jig plate 11, the wiring arm 13, the processing arm 14, and the jig arm 15. The wire harness 1 is wired to the jig plate 11 by the slide drive section 23, the wiring arm 13, the processing arm 14, and the jig arm 15 whose driving is controlled by the control section 16.

Next, various examples of wiring work for the wire harness 1 by the control unit 16 will be described.
In addition, in the following wiring work example, as shown in FIG. The electric wire 2A and the second electric wire B are routed in a branched state.

(Routing work example 1)
2 to 4 are schematic configuration diagrams of a wiring device for explaining example 1 of wiring work.
As shown in FIG. 2, the first electric wire 2A and the second electric wire 2B are routed by the wiring arm 13. Specifically, the first connector 3A is held by a connector jig 12A. Then, the first electric wire 2A is held by the electric wire jig 12B, and the second connector 3B is further held by the connector jig 12D. Further, the second electric wire 2B is held by the electric wire jig 12B, and the third connector 3C is held by the connector jig 12E.

As shown in FIG. 3, a jig 12C is added to the jig plate 11 using the jig arm 15, and is locked to the first electric wire 2A between the jig 12B and the jig 12D. Then, as shown in FIG. 4, by moving the jig 12C toward the second electric wire 2B (in the direction of arrow D1 in FIG. 4), the first electric wire between the jig 12B and the jig 12D is moved. 2A is drawn to the second electric wire 2B and made to run along the second electric wire 2B. Thereby, the added jig 12C forms a branch point S between the first electric wire 2A and the second electric wire 2B.

According to the above procedure, even if the branching point S is close to the jig 12D or the jig 12E, and therefore the jig 12C is added using the jig arm 15, even if it is difficult to perform the wiring work using the jig arm 13. By moving the branch point S, the branch point S can be easily formed.

(Routing work example 2)
5 to 7 are schematic configuration diagrams of a wiring device for explaining example 2 of wiring work.
As shown in FIG. 5, the first connector 3A is held by the connector jig 12A by the wiring arm 13. Then, the first electric wire 2A is held by the electric wire jigs 12B and 12C, and the second connector 3B is held by the connector jig 12D. Further, the second electric wire 2B is held by the electric wire jigs 12B and 12C, and the third connector 3C is held by the connector jig 12E. Thereby, in the jig 12C, a branch point S between the first electric wire 2A and the second electric wire 2B is formed. At this time, the jig 12D is placed on the side of the jig 12C and separated from the jig 12E.

As shown in FIG. 6, the processing arm 14 processes the first electric wire 2A from the branch point S to the second connector 3B. As an example, tape winding is performed in which the tape T is wound between the branch point S of the first electric wire 2A and the second connector 3B. In this tape winding, the processing arm 14 rotates the tape reel held by the robot hand 14a around the first electric wire 2A of the wire harness 1 to wind the tape T. Therefore, a large movable space is required around the first electric wire 2A to be wrapped with tape.

At this time, since the jig 12D is placed on the side of the jig 12C and separated from the jig 12E, the area between the branch point S of the first electric wire 2A and the second connector 3B is wrapped with tape. Sufficient space is secured. Therefore, the tape winding process for the first electric wire 2A can be performed satisfactorily.

As shown in FIG. 7, after the first electric wire 2A is wrapped with tape, the jig 12D holding the second connector 3B is changed to the jig 12E holding the third connector 3C by the jig arm 15. (in the direction of arrow D2 in FIG. 7), bring it close to the jig 12E holding the third connector 3C, and install it at the regular position.

(Routing work example 3)
8 to 10 are schematic configuration diagrams of a wiring device for explaining example 3 of wiring work.
As shown in FIG. 8, the first connector 3A is held by the connector jig 12A by the wiring arm 13. Then, the first electric wire 2A is held in the electric wire jig 12B and the jig (first jig) 12C, and the second connector 3B is held in the connector jig (second jig) 12D. hold it. Further, the second electric wire 2B is held in the electric wire jig 12B and the jig (first jig) 12C, and the third connector 3C is held in the connector jig (third jig) 12E. hold it. Thereby, in the jig 12C, a branch point S between the first electric wire 2A and the second electric wire 2B is formed. At this time, the sub-jig plate 21 on the jig plate 11 on which the jig 12B is erected is slid toward the sub-jig plate 21 on which the jig 12A is erected. As a result, the sub-jig plate 21 on which the jig 12B is erected is brought closer to the sub-jig plate 21 on which the jig 12A is erected, and the sub-jig plate 21 on which the jig 12C is erected is brought closer to the sub-jig plate 21 on which the jig 12C is erected. Separate. Then, the jig 12B is placed at a position farther from the branching jig 12C than the normal position.

As shown in FIG. 9, the processing arm 14 processes the first electric wire 2A and the second electric wire 2B between the jig 12B and the jig 12C. As an example, a tape winding process is performed in which a tape T is wound around the first electric wire 2A and the second electric wire 2B. In this tape winding, the processing arm 14 rotates the tape reel held by the robot hand 14a around the first electric wire 2A and the second electric wire 2B of the wire harness 1 to wind the tape T.

At this time, since the jig 12B is located further away from the jig 12C than the normal position, sufficient space is secured at the tape-wrapped portions of the first electric wire 2A and the second electric wire 2B. Therefore, the tape winding process for the first electric wire 2A and the second electric wire 2B can be performed satisfactorily.

As shown in FIG. 10, after the first electric wire 2A and the second electric wire 2B are wrapped with tape, the sub-jig plate 21 is slid, and the sub-jig plate 21 on which the jig 12B is erected is It is moved away from the sub-jig plate 21 on which the jig 12A is erected, and brought close to the sub-jig plate 21 on which the jig 12C is erected. As a result, the jig 12B is moved toward the branching jig 12C (in the direction of arrow D3 in FIG. 10) and placed at the normal position. In addition, in the wiring work example 3, as in the other wiring work examples, the jig 12 is gripped and moved by the jig arm 15 as necessary.

As described above, according to the wiring device 100 according to the present embodiment, the jig arm 15 controlled by the control unit 16 adjusts the position of the jig 12, so that the jig arm 13 and The movable space of the processing arm 14 can be expanded. Therefore, the wiring work on the jig plate 11 can be performed smoothly, and the number of wire harnesses 1 that can be used for the wiring work can be increased.

Further, the control unit 16 causes the plurality of sub-jig plates 21 to be spaced close to each other or spaced apart when the wiring arm 13 is used for wiring and when the processing arm 14 is used for processing. Thereby, by bringing the sub-jig plates 21 close to each other during wiring by the wiring arm 13, the moving distance of the wiring arm 13 can be shortened, and the wiring time can be shortened. Furthermore, by separating the sub-jig plates 21 from each other during processing by the processing arm 14, the space in which the processing arm 14 can move can be increased. Thereby, the wiring work of the wire harness 1 to the jig plate 11 can be performed smoothly and in a short time. Further, since the interval between the sub-jig plates 21 can be adjusted depending on the type of wire harness 1, the present invention can be applied to even more types of wire harnesses 1.

In particular, since the movable space of the machining arm 14 can be widened by moving the jig 12, tape winding work requires a wide movable space because the held tape reel is rotated around the wire harness 1 to wind the tape T. can be carried out smoothly without contact with the jig 12, and furthermore, it is possible to process up to the vicinity of the branch point S.

Note that the present invention is not limited to the embodiments described above, and can be modified, improved, etc. as appropriate. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiments are arbitrary as long as the present invention can be achieved, and are not limited.

For example, in the above description, the plurality of jigs 12 are moved by the jig arm 15, but some or all of the jigs may be moved by the operator. In addition, although the case has been described in which the jig 12 is attracted to the upper surface of the sub-jig plate 21 by the magnetic force of the magnet and is erected, it is also possible to install a device such as a suction cup that can be attached to and detached from the jig plate 21 instead of a magnet.
