DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a wire harness,
Following the wiring process, the wire stripping process and the terminal crimping process can be performed continuously.

The present inventors previously filed Japanese Patent Application No. 53-079510 (Japanese Unexamined Patent Publication No. 55
-6732), it is possible to route and cut the wires at the same time, and when cutting the wires, the terminals of the wires are arranged at appropriate intervals using bridges, and the subsequent connection terminal fittings are arranged at appropriate intervals. We have proposed a method and device for manufacturing a wire harness that makes it extremely easy to connect and attach connectors.

This is the product (wire harness) in advance on the workbench.
A wiring table arranged according to the wiring configuration, a wiring jig that can be raised and lowered to move up and down on a wiring head that runs on the XY axes, and a wire clamp that clamps and cuts the wires. A mechanism routes and clamps the wires between the desired wiring tables and cuts them at the same time, which is different from the conventional method of holding and transporting wires cut to a predetermined length by both ends. It was something fundamentally different.

After the wiring is completed, the workbench is moved to a welding process, and after the bridge and wires are welded and fixed, the wire harness is removed from the wiring table, and the wires are stripped and the terminals are crimped in a separate process. Ta.

This will be explained in detail below with reference to the drawings.

It is provided in a symmetrical position.

FIG. 4 is a perspective view of the bridge. Bridge C
is used to hold the end portions of electric wires at regular intervals, and a pair of welded pieces 17,
It is formed by connecting a large number of wires 17' at regular intervals, and is used by cutting it appropriately according to the number of wires to be wired. This bridge C is usually made of the same type of thermoplastic resin as the insulation coating of the electric wire W, and is fixed by welding after the electric wire is wired.

FIGS. 5A to 5C are explanatory diagrams showing the process of wiring, clamping, and cutting electric wires using the wiring table A, the wiring jig 8, and the clamping jig 10.

First, at the starting point of the wiring (FIG. 5A), the bridge C is placed in the bridge mounting groove 2 of the wiring table A-1 in advance, and the wiring nozzle 9 is placed between the bridge C and the nozzle guide pin 1. The end portion (length 1) of the electric wire W that is bent and contacted and exposed from its tip is located above the wire clamp claws 3 .

In this state, when the clamp jig 10 is lowered,
As shown in FIG. 5B, the wire terminal insertion guide plate 12
comes into contact with the electric wire W. As a result, the wire W is guided to the center of the wire clamp claw 3, then pressed by the front end clamp plate 11 and held between the clamp claws 3, and at the same time, the welded pieces 17, 1 of the bridge C
It is located between 7' and routed.

That is, even if the wire W exposed from the tip of the wiring nozzle 9 is slightly bent at the starting point of the wiring, it is straightened by the cooperative mechanism of the wire end insertion guide plate 12 and the front end clamp plate 11. It is securely locked to the wiring table A-1.

FIG. 5C shows the end point of the wiring, and shows the wiring table A-
The wiring nozzle 9 enters from the nozzle guide pin 1 side of the wiring table A-2, which is arranged opposite to the wiring table A-2.
The electric wire W is bent and contacts the nozzle guide groove 5, and the electric wire W protruding from the tip thereof is linearly connected to the wiring table A-1 via the nozzle guide pin 1 and a pin on the work table (not shown). It is set up on. Therefore, the wire W is aligned with the center of the wire clamp claw 3 and the welded pieces 17, 17' of the bridge C, respectively.

In this state, when the clamp jig 10 is lowered, the electric wire W is pressed by the rear terminal clamp plate 15 on the opposite side from the front terminal clamp plate 11 in FIG. It is cut by the cutting blade 14 leaving an end portion (length l) on the cutting blade contact surface 4.

Next, the clamp jig 10 is rotated by the operation of the regulating rotation motor M (FIG. 2), and the wiring jig 8
If it is located directly after the line, it will return to the starting point of the wiring as in the case of Fig. 5A. In this way, the wiring head A equipped with the wiring jig 8 and the clamp jig 10
By running the wires between desired wiring stands, the wires are continuously routed and cut, and both ends of the wires W are connected to the welded pieces 1 of the bridge C, one by one.

However, according to the above-mentioned method, following the wiring process (locking, routing, and cutting of the wire), stripping and
The terminal crimping process cannot be made continuous. That is, the wiring table A cooperates with the wiring head B, which includes the wiring jig 8 and the clamp jig 10, so that
Although it has a structure suitable for automating the wiring process,
It does not have the structure necessary for stripping wires and crimping terminals. Therefore, the wiring process (and welding process)
After completing the process, it was necessary to remove the wire harness from the wiring stand and process it with another device.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to continuously perform the wiring process, wire stripping process, and terminal crimping process by improving the structure of the wiring table. An object of the present invention is to provide a method for manufacturing a wire harness.

Another object of the present invention is to simplify the manufacturing process and shorten the manufacturing time by simplifying the manufacturing process and shortening the manufacturing time by making the above-mentioned processes continuous and by omitting the process of welding the wires and the bridge, thereby making it possible to manufacture wire harnesses at low cost. We are here to provide you with a method.

As shown in FIG. 9, the cutting blade 48 has a structure in which blade portions 48b and contact plate receiving surfaces 48c are alternately provided on the upper part of the cutting blade main body 48a. In addition, in correspondence with the provision of this cutting blade 48 on the wiring table 20 side, the cutting blade 14 (the third
10, a clamping jig 10' provided with a cutting blade contact plate 14' is used instead.

The terminal crimping section 24 is composed of a plurality of anvils 54, a pair of side arms 55, and a rear arm 56, and the anvil 54 is removably erected on an anvil stand 57 fixed to the front end of the base 27.

By providing the cutting blade 48 on the wiring head 20 and the cutting blade contact plate 14' on the clamp jig 10', a plurality of electric wires can be locked and cut between a pair of clamp claws 33, 33. be able to. FIG. 11 shows this state. First, as shown in A, when the clamp jig 10' descends, the first electric wire _W1 is cut by the cutting blade contact plate 14' and the blade part 48b, This is exactly the same as in FIG. 5C above. On the other hand, when the second electric wire W ₂ is routed in an overlapping manner, the second electric wire W ₂ is connected to the clamp jig 1 as shown in B.
0' is then pressed by the terminal clamp plate 15 and pushed between the wire clamp claws 33. Therefore, the first electric wire ₁ is pressed by the electric wire _W2 and escapes to the electric wire clamp claw 33, and the tip of the electric wire _W1 descends along the flank 48d of the blade portion 48b. As a result, the second electric wire W ₂ is connected to the blade part 4 of the cutting blade 48.
8b and is cut in exactly the same condition as in FIG. 11B.

In this way, the wiring head B and the wiring table 2
When the automatic wiring process by No. 0 is completed, the workbench D is transferred to the next station and the wire stripping process begins.

FIGS. 12A to 12C are explanatory diagrams showing the process of stripping the wire.

In the figure, 59 indicates a peeling machine, and the peeling machine 59
and the wiring table 20 constitute a peeling device.
This peeling machine 59 is provided so as to be movable up and down in accordance with the number of wiring tables 20 disposed on the workbench, and has a frame (not shown) that fits into the positioning hole 35. The case 60 is provided so as to be tiltable relative to the pin, a pressing body for the lock lever 36, and an electric wire pressing plate located between the pressing bodies.

A fusing blade 61 and a receiving blade 62 for the insulation coating of the electric wire are attached to the lower front surface of the case 60 so as to be able to move upwardly and downwardly.

That is, the fusing blade 61 is screwed onto a mounting base 63 containing an electric heater so as to be movable up and down with an adjustment screw 64, and the mounting base 63 is fixed to an upper holder 66 via a heat insulating material 65. Further, the receiving blade 62 is fixed to the lower holder 67 with a screw 68. The upper holder 66 and the lower holder 67 are connected to two guide pins 7 protruding from the top and bottom of the frame 69.
0.70' is inserted so that it can be raised and lowered. 71 is an air cylinder that opens and closes the fusing blade 61 and the receiving blade 62. The tip of the air cylinder 71 is screwed into the screw hole 72 of the upper holder 66, and the piston 7
1a extends through a coil spring 73 interposed between the upper holder 66 and the frame 69, and its tip further passes through a hole 74 in the lower holder 67 and is fixed to the lower surface of the lower holder 67 with a screw.

Further, 75 is a stopper screw that prevents the fusing blade 61 from shifting upward, 76 and 78 are limit switches, 77 and 79 are respective operating levers, and 80 is a pressing pin for the operating lever 79.
A hole 81 for a press pin 80 is bored in the frame 69.

FIGS. 13A and 13B are enlarged explanatory views of the fusing blade 61 and the receiving blade 62. The fusing blade 61 is constructed by joining a reinforcing plate 82 having a wide inverted U-shaped groove 82a and a thin plate-like main body 83 having a narrow inverted U-shaped fusing groove 83a, and the width of the fusing groove 83a is outside the conductor. Take approximately equal to the diameter. On the other hand, the receiving blade 62 is configured by providing a V-shaped holding groove 84 for the electric wire at its upper end.

When the work table D is transferred to the next station upon completion of the wiring process, the peeling machine 59 corresponding to each wiring table peels the case 60 against the frame as shown in FIG. 12A. Descend with the door open.

As a result, the pressing body of the frame presses down the lock lever 36 of the wiring table 20, and locks the lock pin 41.
and the lock claw 42 of the base 27, and at the same time, the wire holding plate of the frame presses and fixes the wire to the clamp portion 22, and the air cylinder 29 operates to release its piston 29a. The base 27 extends and contacts the piston receiver 30, and the base 27 retreats. Then, the fusing blade 61 and the receiving blade 62 face the front surface of the electric wire W locked by the electric wire clamp claw 33 of the wiring table 20 in an open state.

Next, as shown in FIG. 12B, the case 60 rotates and approaches the electric wire W side, and the case 60
As the inner air cylinder 71 descends, its piston 71a retreats into the cylinder. As a result, the upper holder 66 and the lower holder 67 move toward the frame 69, and as a result, the fusing blade 61 and the receiving blade 62 approach and sandwich the electric wire W from above and below.

At this time, as the upper holder 66 is lowered, the operating lever 77 of the limit switch 76 is released from the press-contact state, and the heater built in the mounting base 63 is energized to instantaneously heat the fusing blade 61. As a result, the melting groove 83a of the cutting blade 61 heats the insulation coating and bites into it, cutting the insulation coating. On the other hand, when the fusing blade 61 and the receiving blade 62 sandwich the electric wire W from above and below, that is, when the upper holder 66 and the lower holder 67 approach each other and the press pin 80 presses against the actuating lever 79, the limit switch 78 is activated, as shown in the figure. A timer circuit turns off the power to the heater after a certain period of time.

Finally, as shown in FIG. 12C, when the case 60 is rotated (swinged) so as to be separated from the electric wire W, the end portion of the electric wire is stripped by the narrow melting groove 83a. In this state, by raising the air cylinder 71 in the case and letting out the piston 71a, the fusing blade 61 and the receiving blade 62 are opened, returning to the starting state shown in FIG. 12A.

In this way, the insulation coating part of the electric wire W is cut by melting with the fusing blade 61 and the receiving blade 62 equipped with heating means,
Next, the method of stripping by a swinging motion eliminates the risk of damaging the conductor portion of the wire and can minimize the space required for stripping.

When the wire stripping process is completed in this way, the workbench D is again transferred to the next station and begins the process of crimping the connection terminal fittings.

FIG. 14 is a side view of the terminal crimping device, and FIG. 15 is an enlarged front view of the main parts thereof.

In the figure, 85 indicates a terminal crimping machine, and the terminal crimping machine 82 constitutes a terminal crimping device together with the wiring table 20 with the wire cutting section 23 removed.

The terminal crimping machine 85 has a structure in which a crimping rod 87 is provided in a frame 86 provided corresponding to each wiring table 20 on the workbench D so as to be movable up and down.

The crimping rod 87 has a crimping groove 88 for the anvil 54 of the terminal crimping part 24 in the wiring table 20,
It is detachably attached to the holder 89. The holder 89 has two plate pillars 90, 9 that constitute the frame 86.
0' and can be raised and lowered freely, and its upper end is connected to a recess 92 of a holder mounting plate 92 by a screw 91.
It is fitted and fixed to a. The holder mounting plate 92 is
Further, a guide pin 9 is provided with holes 92b bored on both sides between the upper frame 93 and the lower frame 94 of the frame body 86.
5 and 95', and a coil spring 96 is interposed between the lower frame 94 and the upper frame 93, thereby biasing the upper frame 93 side. Further, on the lower surface of the lower frame 94, a fitting pin 97 for the positioning hole 35 of the wiring table 20 is provided.
A support pin 98 that abuts against the convex portion 55a of the side arm 55 is bored. Note that 99 is an adjustment screw for adjusting the position of the crimp rod 87.

FIG. 16 is an exploded perspective view of a cassette that holds connection terminal fittings.

The cassette 100 includes a case body 101 and a lid body 1.
02 with a presser spring 103 interposed between it and the screw 10.
4, the case body 101 is provided with cutout recesses 105 on both sides, a spring chamber 106 inside, and an insertion groove 107 for the terminal fitting F at the front. This cutout recess 105 is located on the wiring table 2.
It is made slightly larger than the protrusion 55a of the side arm 55 in 0 so that it can be fitted loosely.

Next, the terminal crimping process will be described. The electrical contact portion F ₁ of the terminal fitting F is inserted into the insertion groove 107 of the cut 100 and held by the presser spring 103.

This cassette 100 is set on the base 27 of the wiring table 20. That is, by pulling the stopper 46 forward, the L-shaped member 43 constituting the wire cutting section 23 is pulled down backward, and the cutout recess 105 of the cassette 100 is loosely fitted into the protrusion 55a of the side arm 55. At this time, the wire connection part of the terminal fitting F
_F2 is supported by the anvil 54, and the cassette 100 is slightly biased forward by a leaf spring 58 of the rear arm 56. Then, the base 27 that had been separated in the peeling process is moved to the wire clamp section 22 side, and the lock pin 41 and lock claw 4 are removed.
2 locks both.

The above operations are performed manually by the operator. This is because it takes a considerable amount of time to route a large number of wires in the wiring process, so there is sufficient time to spare, and defective products may occur when crimping the terminal fittings to the wires. This is to avoid affecting the entire harness.

After the above operation, as shown in FIG. 14, the terminal crimping machine 85 is lowered toward the wiring table 20, and the frame body
6 is positioned and set on the wiring table 20 using the fitting pin 97, support pin 98, etc.

Next, by operating a press ram (not shown) and pressing the holder mounting plate 92, the crimping rod 87 is lowered, and the wire connecting portion _F2 of the terminal fitting F is connected to the conductor of the wire W by the crimping groove 88 and the anvil 54. It is caulked and crimped. Then, by raising the press ram, the holder mounting plate 92 returns to its original state due to the elastic force of the coil spring 96.

In this way, the wiring table 20 cooperates with the wiring head B to function as a wiring machine for locking, routing, and cutting electric wires, and also has a wire cutting section for the wire clamp section 22. 23 and the terminal crimping section 24 are provided so as to be separable, so that together with the stripping machine 59 and the terminal crimping machine 85, an electric wire stripping and terminal crimping apparatus is constructed. As a result, after wiring wires between wiring tables, that is, when moving from the wiring process to the next stripping and terminal crimping process, the wires are not removed from the wire clamp part of the wiring table. It can be moved as it is in the locked state, and there is no need to weld and fix the electric wire with a bridge as in the conventional case. Therefore, instead of the conventional welding type bridge C (see Figure 4), it is recommended that the bridge be detachably attached to the end of the wire, and that it can be removed after the terminal fitting is inserted into the connector. preferable.

Figure 17 shows such a bridge.
The bridge 108 has a wire holding part 1 on a substrate 109, which is made up of a pair of holding pieces 111 and 111' facing each other.
It has a configuration in which multiple sets of 10 are arranged in parallel. The clamp holder 111, 111' is formed into a double structure with a flexible inner plate 111a and an outer plate 111b, and the opposing inner walls 111a,
By making the interval between the wires 111a slightly smaller than the outer diameter of the wire, as shown in FIG.
When inserted between the clamps 111 and 111', the inner plate 111a curves toward the outer wall 111b, thereby elastically clamping the electric wire.

In this way, the bridge 108 has a pair of clamps 11
It is configured such that it can be detachably attached to the end portion of the wire by means of a wire holding portion 110 made of 1,111'. Therefore, the bridges 108 can be set in advance in the bridge mounting grooves 32 of each wiring table 20 before entering the above-mentioned wiring process, and can hold the electric wires at the same time as wiring the electric wires. It can also be attached at any desired stage of the wiring process or terminal crimping process, or when the wire is removed from the wiring board after terminal crimping. After it is inserted, it can be removed.

The above has described an example in which the wire cutting section 23 of the wiring table 20 is pivotably attached to the base 27, but the point is that the wire cutting section 23 and the terminal crimping section are separable and that they are connected to the wire clamp section 22. Various design changes are possible as long as it can be configured to be able to come into contact with and separate from it. Further, in place of the cutting blade 48 in the wire cutting section 23, a cutting blade abutting surface 4 (FIG. 1) can be provided as in the past, and it can be used in combination with the clamp jig 10.

The peeling machine 59 also includes a fusing blade 61 and a receiving blade 6.
Instead of 2, the skin may be stripped by attaching a pair of upper and lower cutting blades (each having a U-shaped or V-shaped grooved blade on the opposing surfaces).

Furthermore, when crimping the terminal fittings F, the terminal crimping section 24 is designed so that instead of inserting the terminal fittings one by one using the cassette 100, a chain-like terminal fitting in which the terminal fittings are connected in a horizontal direction can be used as is. It is also possible to make design changes to the side arm 55, rear arm 66, etc.

As described above, the method for manufacturing a wire harness of the present invention uses a wiring stand equipped with a wire clamp section, a wire cutting section and a terminal crimping section that move toward and away from the wire clamp section, (a) After placing the wiring table in advance on a workbench with a product interval, and locking it to the wire clamp part of the first wiring table by a wiring head having a wiring jig, a clamp jig, and a wire cutting member. The wire is routed toward another wiring table, the wire is locked to the other wiring table, and the wire is cut at the wire cutting portion that is close to the wire clamp portion. a wiring step of sequentially routing the wires between desired wiring tables; (b) in a state where the wire cutting section and the terminal crimping section are separated from the wire clamp section of the wiring table; (c) moving the wire crimping section toward the wire clamping section and separating the wire cutting section from the terminal crimping section; , a terminal crimping step of crimping a terminal fitting to the end portion of the stripped wire that is locked in the wire clamp section. The process of stripping the electric wire and crimping the terminal to the electric wire following the wiring process can be performed immediately with the electric wire locked to the wire clamp part of the wiring table during the wiring process on the workbench. Compared to conventional methods, the time and labor required for manufacturing wire harnesses can be greatly reduced, and this method is suitable for low-cost mass production of wire harnesses.
