The wire harness 19 is constructed by assembling the components described above or applying the tape winding 12.

[0003] Since the shape of the wire harness 19 is complicated, the work of laying the electric wire 4 and the work of attaching the parts 10 to 12 are performed by using instructions, connectors and parts drawn in advance on the wiring board 51, and the like. The operator performs the work manually while watching the picture. Each component 10 to 11 is appropriately taken out of the component cases 13 to 15 by an operator and assembled to the electric wire 4.

The ties 5 to 7 on the wiring board 51 are shown in FIG.
As shown in FIG. 0, various shapes are used.
In FIG. 10, 5 is a jig for hooking the electric wire 4 and arranging it in one direction, 6 is a fork jig capable of branching the electric wire 4 in the other direction, 7
Is an indicator for designating the range of the tape winding 12. Various types of wiring boards 51 are set in accordance with the high-mix low-volume production of the wiring harness 19, or the wiring boards 51 are shared, and the fasteners 5 to 7 are rearranged and used according to the harness specifications. Was.

In the next step, the wire harness 19 after completion of the wiring is inspected by a continuity inspection tool 24 as shown in FIG.
A large number of the continuity inspection tools 24 are provided corresponding to the number of connectors, and the inspection of each connector portion 8 is performed simultaneously. FIG.
Reference numeral 52 denotes a fixing portion for holding the rear half of the connector 8;

The laser beam 2 irradiates the assembling positions (1) to (12), thereby instructing a worker on a work location.

The worker arranges the electric wire 4 at the beam irradiation position on the wiring board 1 and scratches the connector 8 with the ligatures 5 to 7 irradiated with the beam. The irradiation position of the beam 2 moves sequentially in the order of wiring, and the worker may perform the wiring according to the instruction of the beam 2. The ties 5 to 7 and the parts 9 to 11 may be instructed to draw a circle with the beam 2. Parts 9-12
Is given by first instructing the component cases 13 to 16 with the beam 2, and then instructing the required position of the electric wire 4. The worker moves the parts 9-1 to the designated parts case 13-16.
1 is taken out and the parts 9 to 11 are assembled to the designated electric wire 4 part. Thus, even a new worker can easily, quickly and accurately perform the wiring work and the assembly of parts. Note that the indicating light 2 is not limited to a laser beam, but may be a halogen lamp or the like, and any so-called visible light can be used.

The wiring guiding device 3 comprises a head 20 provided with a laser emitting unit and an XY driving unit, which will be described later, a frame 17 for instructing the head 20, and a controller 18 connected to a circuit in the frame 17. You. The controller 18 sequentially determines the irradiation position of the beam 2 according to data (coordinate data and the like) input in advance, and moves the XY drive unit to irradiate the beam 2 to a required position.

The guiding device 3 is installed separately from the wiring board 1, and continuously moves a plurality of wiring boards 1 along a conveyor or the like (not shown), or connects other wiring boards. The same guiding device 3 can be used for the board 1 '. In addition, it is of course possible to fix and use the guidance device 3 to the wiring board 1. When the guidance device 3 is separate, it is necessary to preliminarily define a reference position with respect to the wiring board.

FIG. 2 shows an example of assembling the ties 5 to 7 on the wiring board 1 as an application example using the above-described guidance device 3. The wiring board 1 can use the fasteners 5 to 7 in various forms according to the specifications of the wire harness 19 (FIG. 1), and the work is performed by the instruction of the beam 2. The ligatures 5 to 7 are, as described in the conventional example, a jig 5 for hooking the electric wire 4 (FIG. 1), a fork jig 6 capable of branching the electric wire 4, and an indicator 7 for designating a tape winding range.

As shown in FIG. On the wiring board 1, a plurality of continuity inspection tools 24 are installed corresponding to the respective connectors (connector portions) 8 of the wiring harness 19, and each connector 8 is set on the respective continuity inspection tool 24. I have. This continuity inspection tool 24 is a conventional example shown in FIG.
It is the same as shown in FIG. And wiring board 1
The continuity test is performed above, and the position of the connector 8 having the continuity failure is irradiated with the beam 2 to be instructed. The operator can easily find the defective part, and quick repair can be performed. Note that the continuity inspection tool 24 may be provided not in the wiring board 1 but in another continuity inspection step (not shown). In that case, the guiding device 3 is arranged in the continuity inspection step.

FIGS. 4 to 6 show the structure inside the head 20 of the guiding device 3. FIG. In the head 20, a first mirror 26 is disposed so as to face a laser emitter (light source) 25, and a second mirror 27 is disposed in a direction orthogonal to the first mirror 26. The rotating bodies 3 are respectively attached to rotating shafts 32 and 33 following the speed reducing sections 30 and 31 of 28 and 29.
The mirrors 26 and 27 are connected via the mirrors 4 and 35, respectively. The laser beam 2 is reflected by the first mirror 26, enters the second mirror 27, and is irradiated on the wiring board 1 through the glass window 36 (FIG. 5).

The mirrors 26 and 27 are provided on the surfaces of rotating bodies 34 and 35 having a semi-cylindrical shape (semicircular cross section) made of metal by pasting or the like, and the mirror surfaces coincide with the centers of the rotating shafts 32 and 33. ing. A pin 37 projects from each of the rotating bodies 34 and 35, and the pin 37 comes into contact with a stopper 38 projecting into the head 20, thereby defining an irradiation range. A tension spring 39 is connected to the rotating bodies 34 and 35 from the outside, and the rotating bodies 34 and 35 are pulled in one direction to prevent backlash of the reduction gears (reducing parts 30 and 31) due to backlash and the like. I have. The positioning in the X direction is performed by one mirror 26, and the positioning in the Y direction is performed by the other mirror 27. The laser emitter 25 and mirrors 26 and 2
7 together with the laser emitting section,
The XY drive section is constituted by the 29 and the speed reduction sections 30 and 31.

FIGS. 7 and 8 show the appearance of the guiding device 3 and the irradiation range of the beam 2. FIG. The guide device 3 is movable and fixed by the casters 42 of the four legs 41 and the adjuster pads 43. The controller 18 is fixed to the center of the leg 41, and has a position data storage unit 44 and a motor driver 45. Further, a selection switch (not shown) for displaying a sound or the like may be provided. The total height of the guidance device 3 is 2000 mm
The irradiation range of the laser beam 2 at the wiring board position is about 3600 mm in the X direction and about 1200 mm in the Y direction. The XY dimensions correspond to the size of the wiring board 1. The beam diameter of the semiconductor laser 2 is about 1 to 5 mm,
The laser power is about 3 to 5 VDC.

[0019]

As described above, according to the present invention, since the visible light of the guidance device indicates the wiring sequence of the electric wires and the parts to be assembled, the operator can simply proceed with the work according to the visible light. Even a new worker can easily, quickly and reliably perform the wiring work. In addition, no training or period for learning is required, and the burden on the concerned parties is greatly reduced. At the same time, incorrect wiring and assembly of different parts are eliminated, and the quality is improved. In addition, since the visible light of the guidance device plays a role of a pacemaker, the operator can always perform the routing and the like at a constant speed, and the production speed is higher than before. Furthermore, by applying the instructions from the guidance device to the ties on the wiring board, the wiring board can be rearranged easily, quickly, and reliably, and it is possible to cope with single wiring and small-lot production of many kinds. In addition, by applying the present invention to a continuity inspection tool, a continuity defective portion can be easily and quickly found out from a large number of connectors, and the number of harness inspection steps is reduced.
