Description

[Detailed description of the invention] ーー0ν, “i・゛ J−ι6′, Agency I Kenharu Police Day 1 ゛日日゜, 3丑゛1 ノ is further laid on top of the already wired wire terminal. The present invention relates to a wiring stand capable of cutting and arranging electric wire ends.

Wire harnesses are generally constructed by combining a large number of electric wires, providing branch lines to the main line, and connecting connectors to each of these lines. Because it requires a great deal of labor and time to manufacture, it has traditionally been difficult to use various automatic wiring methods. A method is proposed.
However, in principle, these methods first cut the wires to a predetermined length and route them between each connector, so while they have the advantage of being able to automate the entire process up to the installation of the connectors, The problem was that it took a long time to produce and the productivity was poor.

Focusing on these points, the present inventors first filed a patent application in 1973.
-079510 (hereinafter referred to as the earlier invention), it is possible to simultaneously route and cut the electric wires, and when cutting the electric wires, the terminal parts of the electric wires are arranged and fixed at appropriate intervals by a bridge, and We have proposed a method and device for manufacturing a wire harness that makes it extremely easy to connect connection terminal fittings and attach connectors. The outline of the prior invention will be explained below with reference to FIGS. 1 to 8.

Different colored wires 6 are connected to each wiring jig 13 from the reel station 9, but the rotation of the wiring jig mounting base 16 interlocked with the regulation rotation motor 17 allows any wiring jig to be connected to the wiring jig 13. 13 can be selectively positioned at a predetermined position P.

In addition, 34 is a regulation rotation motor that rotates the clamp jig 14. FIG. 3 is an enlarged side view of the clamp jig 14. The clamp jig 14 includes, in order from the front, a clamp plate 20 for the front end, a wire end insertion guide plate 21 with a built-in coil spring 21a, a cutting blade 22, and a wire end insertion guide plate 21 for the rear end. A clamp plate 23 is provided, which connects the guide plate 21 and the cutting blade. 22 is provided slightly protruding from the lower surfaces of the front and rear end clamp plates 20 and 23 and perpendicular to each other. The front end clamp plate 20 and the rear end clamp plate 23 are provided at symmetrical positions with respect to the cutting blade 22. FIG. 4 is a perspective view of the wiring table 7, in which a plurality of nozzle guide pins 2 are provided at the front end of the upper part, a nozzle guide groove 28 is provided at the rear end, and a bridge 30, which will be described later, is placed in the middle. A groove 25, a wire clamp claw 26, and a cutting blade contact surface 27 are provided.

Note that 29 is a release screw for the wire clamp claw 26. The nozzle guide pin 2 (male) nozzle guide groove 28 and the like are increased or decreased depending on the number of wires to be wired, and are used to guide the wiring nozzle 12 of the wiring jig 13 during wiring, and are also used as wire clamps. The claw 26 is responsible for holding the electric wire during wiring and holding the electric wire until the welding process, and can only hold down the inserted electric wire.

FIG. 5 is a perspective view of the bridge 30.

The bridge 30 holds the end portions of the electric wires at a constant interval, and a pair of welded pieces 33, 33'' having a sloped portion 32 at the outer upper end are placed on a thin strip-shaped substrate 31 at a constant interval. It is formed by connecting a large number of sets in the horizontal direction, and is cut as appropriate depending on the number of wires to be used.This bridge 30 is preferably made of the same type of thermoplastic resin as the insulating coating of the wire. Instead of the welding pieces 33, 33'', flexible clamping pieces may be provided to hold them. 6th
The figure shows the correspondence between the wiring table 7, the wiring jig 13, and the clamp jig 14. At the starting point of wiring (FIG. 6A), the bridge mounting groove of the wiring table 7-1 A bridge 30 is placed in advance on 25, and the wiring nozzle 1 of the wiring jig 13 is placed between the bridge 30 and the nozzle guide pin 24.

Therefore, the wire 6 is guided to the center of the wire clamp claw 26, then steadily pressed by the front end clamp plate 20 and held between the clamp claws 26, and at the same time positioned between the welded pieces 33, 33'' of the bridge 30. In other words,
At the starting point of the wiring, even if the wire exposed from the tip of the wiring nozzle 12 is slightly bent, the wiring table is steadily moved by the cooperative mechanism of the wire end insertion guide plate 21 and the front end clamp plate 20. 7-1.

FIG. 6C shows the end point of the wiring, and the wiring table 7-2 is placed opposite the wiring table 7-1.

In addition, the wiring nozzle 12 of the wiring jig 13 bends into contact with the nozzle guide groove 28, and the electric wire 6 exposed from the tip is inserted through the wiring locking pin 35 and the nozzle guide pin 24, which will be described later. and the wiring table 7-1. Therefore, the electric wire 6 is aligned with the center of the electric wire clamp claw 26 and the welded pieces 33, 33'' of the bridge 30, respectively.In this state, when the clamp jig 14 is pushed down, the electric wire 6 is positioned at the rear. The cutting blade 2 is steadily pressed by the terminal clamp plate 23 and held between the clamp claws 26, and at the same time leaves the terminal part (length l) on the cutting blade contact surface 27.

Next, the regulating rotation motor 34 (the ninth
If the cable is rotated by the operation of the cable (see figure) and positioned directly behind the wiring jig 13, it will return to the starting position of the cable in the same way as the connection shown in Fig. 6A.

FIG. 7 shows a wire harness manufactured by the above apparatus.

That is, a plurality of wiring locking pins 3 are placed in advance at predetermined positions on the workbench 1.
5 and a wiring table 7 are arranged, and the wiring table 7 has a bridge 30
is placed.

The electric wire 6 is successively placed between the welded pieces 33 and 33'' of the bridge 30 on the wiring table 7 by a cooperative mechanism between the wiring head 5, which includes a wiring jig 13 and a clamp jig 14, and the wiring table 7. At the same time, the end portion of each electric wire 6 is cut off from the bridge 30 leaving a predetermined length l, and is routed to connect each wiring table 7. This is a tape for temporarily fixing the branch parts of the electric wires 6. By using the wiring table 7 having the structure as shown in FIG. I can do it.

However, this wiring table has the inconvenience that it cannot be used when it is necessary to bundle a plurality of electric wires and joint their terminal parts. To explain this with reference to FIG. 8, one electric wire 6a is already routed on the wiring table 7, and the end thereof is located at a certain distance 1 from the wire clamp claw 26 to the cutting blade contact surface 27. It is located at the top (Figure 8a). Therefore, when wiring the second electric wire 6b on this electric wire 6a, the cutting blade 22 of the clamp jig 14 does not reach the cutting blade contact surface 27, making it impossible to cut the electric wire (see Figure 8). . Note that the cutting blade 22
Clamp claw 2 that locks the electric wire 6 even if the cutting edge is slightly longer
6 and the front and rear terminal clamp plates 20, 23 are broken, and the electric wires cannot be locked. The present invention has been made with attention to such points, and an object of the present invention is to provide a wiring table having a structure in which a plurality of electric wires can be stacked, and locking and cutting can be performed simultaneously.

The present invention will be explained below with reference to the drawings.

In FIGS. 9A to 9B, 37 indicates a wiring table, and a nozzle guide pin 39 is provided at the upper front end of the main body 38, and nozzle guide grooves 40 and 41 are provided at the front and rear.
A pair of wire clamp claws 42, 422 adjacent to the rear of the
will be established.

This is substantially the same as the wiring table 7 described above. In the present invention, a wire holding groove 43 for holding a plurality of wires is provided between the lower portions of the wire clamp claws 42, 42'', and a cutting blade is provided facing the recess 44 between the claws 42, 42' and the nozzle guide groove 41. A pedestal 45 is provided so as to be movable up and down and rotatable.

This cutting blade holder 45 has a pair of arms 46, and is pivotally supported by the main body 38 of the wiring table via the arms 46. A tension spring 49 is pivotally supported on the main body 38 by cam grooves 47 and 48, and a tension spring 49 is provided between the middle part of the arm 46 and a part of the main body 38 that is higher than the middle part on the opposite side to the wire clamp claw. provided.

The cutting blade holder 45 to the arm 46 are connected to this spring 49.
Usually, there are wire clamp claws 42 and 4 above the main body 38.
2" and inclined toward the nozzle groove 41 side. A wire guide notch 50 is provided on the wire clamp claw 42, 42" side in front of the cutting blade holder 45.
Arm-lifting cams 51 having oblique engagement surfaces are provided on both sides of the arm 0 to protrude upward.

7. This arm lifting cam 51 engages with the cutting blade 22 to pull up the arm 46.

Note that the locking pins 54 of the spring 49 are stoppers of the arm 46. Next, the operation of the wiring table 37 will be explained.

1> In FIG. 10A, the electric wire 6 is routed on the wire clamp claws 42, 42'' of the wiring table 37 and the cutting blade holder 45.

At this time, the arm 46 is pulled diagonally upward by the tension of the spring 49 with the lower end 01 of the cam groove 47 as the center of rotation. Note that the wiring of the electric wires is performed using a wiring jig 13, as shown in FIGS. 6A to 6C. <2> Next, the cutting blade 22 of the clamp jig 14 is lowered,
When it comes into contact with the inclined surface 51a of the arm lifting cam 51,
The arm 46 is pulled up centering on 01 of the cam groove 47 by a component force in the horizontal direction on the surface 51a.

That is, the horizontal component force and the vertical component force generated on the inclined surface 51a by the cutting blade 22 are Fh and F■, respectively, and the spring 4
If the horizontal component force and vertical component force due to 9 are respectively '111 and Tv, the tension and angle of the spring are adjusted so that Fh>Th and Fv>Tv.

As a result, the arm 46 is raised centering on 01 of the cam groove 47. (Figure 10) <3> When the cutting blade 22 further descends, the arm 46 is pushed down along the cam groove 47, and the electric wire 6 is pushed down and cut accordingly.

At this time, the center of rotation of the arm 46 moves to the upper end 02 of the cam groove 47 against the spring 49. (Fig. 10 C) <4> Next, even if the cutting blade 22 starts to rise, the arm 4
6 is locked by the upper end 02 of the cam groove 47, so it remains in this position, and when the cutting blade 22 leaves the inclined surface 51a, it tilts rearward about 02 by the action of the spring 49.

At this point, the camshaft 48 is disengaged from the 02, and the arm 46
rises obliquely upward along the cam groove 47. (FIG. 10D) <5> Since the arm 46 is raised while being tilted by the spring 49, it returns to its original position (FIG. 9A) without flipping up the end portion of the already cut electric wire 6.

At that time, a notch 5 for guiding the electric wire is provided in front of the cutting blade holder 45.
0 is open, so the electric wire 6 does not touch it at all. (1st
(Fig. 0 E) Therefore, when cutting the next electric wire on top of the electric wire 6, as shown in Fig. 10 The new electric wire is cut and clamped while pressing it down (Fig. 10C).

At this time, since a wire holding groove 43 is provided between the lower portions of the wire clamp claws 42, 42'', it is possible to hold a plurality of wires in a stacked manner. As a result, as shown in FIG. 11, a wire having a desired wiring configuration, including a portion A in which the terminal portions of each electric wire 6 are held at regular intervals by the bridge 30 and a portion B in which a plurality of electric wires are stacked and converged, is formed. Harnesses can be manufactured.

As described above, the present invention includes a pair of wire clamp claws 42, 42'' on the upper part of the main body 38, and a wire holding groove for holding a plurality of wires formed between the lower portions of the pair of wire clamp claws 42, 42''. 43 and a cutting blade holder/base 45 provided on one side of the wire clamp claws 42, 42'', and locks and cuts the wire by raising and lowering the clamp jig 14, which includes the clamp plate 20 and the cutting blade 22. In this wiring table, an arm pulling cam 51 having an oblique engagement surface is provided to protrude upward, and the wire clamping claws 42, 4
Cutting blade holder 45 with a wire guide notch 50 on the 2″ side
is rotatably supported via an arm 46 to the main body 38 so that it can be raised and lowered and rotated in a direction away from the wire clamp claws 42, 42''.
A tension spring 49 is provided between 2, 42'' and a portion above the intermediate portion on the opposite side, and when the cutting blade 22 is lowered relative to the main body 38, the cutting blade 22 engages with the arm pulling cam 51. As a result, the cutting blade holder 45 to arm 46 are pulled up against the tension spring 49, and then the cutting blade holder 45 to arm 46 are pushed down against the tension spring 49. It becomes possible to simultaneously cut a plurality of electric wires while sequentially overlapping and locking them on the wiring table.
