Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring apparatus, and more particularly to a cloth for wiring electric wires constituting a conductive circuit in an electric connection box in a process of manufacturing an electric connection box used for electric wiring. The present invention relates to a wire device.

[0002]

2. Description of the Related Art Conventional electric connection boxes used for electric wiring include an electric connection box in which a conductive circuit is formed by a bus bar and an electric connection box formed by a covered electric wire.

A bus bar is formed by stamping a single metal plate with a press machine. Therefore, an electric junction box in which a conductive circuit is formed of a bus bar requires an extremely expensive mold and a large-scale press to form the bus bar. In addition, there are many portions that become unnecessary portions when the metal plate is punched out, so that there is a problem that the material cost is increased. In addition, since the conductive surfaces of the bus bars are exposed, there is a possibility that adjacent bus bars may be short-circuited.

[0004] On the other hand, an electric connection box in which a conductive circuit is formed of a covered electric wire has high utility value because it can solve the above-mentioned problems of the bus bar. Therefore, conventionally, various wiring methods and wiring machines for forming a conductive circuit with covered electric wires have been proposed.

[0005] Conventionally, there are roughly two methods of wiring a covered electric wire. (1) A method in which wiring is applied to a mold on which a wiring pattern is formed by a wiring machine, and thereafter, the covered electric wires are transferred from the mold to a wiring board.

(2) A method of applying wiring directly to a wiring board by a wiring machine. The method (1) is effective when the material of the wiring board is soft, since the wiring board itself does not directly receive the stress on the coated electric wire generated at the bent portion of the covered electric wire at the time of wiring.
However, the process involves transferring the covered wire from the mold to the wiring board, which complicates the manufacturing process, and if the wiring pattern of the covered wire is complicated, the transfer of the covered wire may fail. is there. The method (2) can compensate for the disadvantage of the method (1), but on the other hand, at the time of wiring, the wiring board itself directly receives stress on the coated electric wire generated at the bent portion of the coated electric wire. In addition, high strength is required for the material of the wiring board.

By the way, in each of the above methods (1) and (2), it is an essential condition that the wiring machine surely wires the covered electric wire. Generally, such a wiring machine supplies a covered electric wire from a head part provided in the wiring machine,
The coated electric wire is laid on the wiring board or the mold by the relative movement between the head and the wiring board or the mold.

[0008] In a conventional wiring machine, a clamp mechanism for gripping and fixing the coated electric wire and a cutting machine for cutting the coated electric wire are arranged on a setting board of the wiring plate or the mold. . Then, at the start of wiring, the covered electric wire is gripped by the clamp mechanism, and wiring is started from the gripped portion. Here, the covered electric wire is pulled out from the head portion with the gripped portion gripped by the clamp mechanism as a fulcrum. The covered electric wire drawn out from the head portion is laid from a starting point in a wiring board or a mold. And
The coated electric wire is laid according to a wiring pattern and reaches an end point portion in a wiring plate or a mold. The coated electric wire that has reached the end point is guided by the cutting machine as it is and cut.
As a result, the head portion and the wired insulated wire are cut off, and the wiring operation is completed.

[0009]

As a conventional wiring machine, there is a wiring machine disclosed in Japanese Patent Application Laid-Open No. Hei 5-260629. An electric wire insertion hole is formed in the head of the wiring machine. Then, the coated electric wire is guided by the electric wire insertion hole and drawn out to the mold.

However, since the electric wire insertion hole and the covered electric wire in the head portion have a large contact area, the frictional resistance when the covered electric wire is pulled out from the head portion is large. Due to the frictional resistance, the coated electric wire may not be pulled out smoothly from the head. As a result, the force of the relative movement between the head portion and the mold is applied to the electric wire, and there is a possibility that the coated electric wire may be damaged or disconnected at the bent portion of the coated electric wire.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a wiring device capable of reliably wiring an electric wire.

[0012]

In order to achieve the above object, according to the first aspect of the present invention, there is provided an electric wire supply means for supplying an electric wire to an object to be laid. Providing a frictional resistance reducing means for reducing frictional resistance when supplying the electric wire, and laying the electric wire on the laid object by relative movement between the laid object and the electric wire supplying means. This is the gist.

According to a second aspect of the present invention, in the wiring apparatus according to the first aspect, the frictional resistance reducing means guides the electric wire while slidingly rotating the electric wire by the electric wire supply means. Is the gist.

According to a third aspect of the present invention, in the wiring apparatus according to the second aspect, the electric wire supply means includes a pair of plates whose plate surfaces are opposed to each other, and between the plates. The gist is that a plurality of the guide rollers whose axis is arranged perpendicular to the respective plate surfaces are provided.

The pressing pin 32 includes a support shaft 32a, a stopper 3
2b and a pressing portion 32c. The pressing portion 32 c of the pressing pin 32 is inserted into the guide groove 25. In this state, the upper part of the support shaft 32a is gripped in the head rotation mechanism 12 (not shown), and the pressing pin 32 is supported in the guide groove 25 so as to be vertically movable. That is, the pressing pin 32 moves vertically in the head portion 13. Pressing pin 3

As described above, the covered electric wire 7 is inserted into the head portion 13. At this time, as shown in FIGS. 3 and 4, the covered electric wire 7 is inserted between the first guide roller 29 and the second guide roller 30 so that the tip of the covered electric wire 7 projects from the lower surface of the head portion 13. In this state, the pressing pin 32 is held at a position where it does not interfere with the covered electric wire 7. When the wiring operation described below is not performed, the covered electric wire 7 is held and fixed by the holding mechanism 11.

Next, the wiring operation of the wiring machine 1 configured as described above will be described with reference to FIGS. In addition,
In this wiring operation, the covered electric wire 7 is released from the holding and fixing by the holding mechanism 11.

FIG. 5 is a plan view of a main part of the wiring board 14 showing a wiring state. The wiring board 14 has partition walls 41 on the upper surface thereof, and wiring grooves 42 are formed between the adjacent partition walls 41. The width of the wiring groove 42 is formed to be slightly larger than the wire diameter of the covered electric wire 7, and the depth of the wiring groove 42 is formed to a depth that allows a plurality of the covered electric wires 7. In FIG. 5, the insulated wire 7, the partition wall 41 and the wiring groove 42 are shown.
In order to clearly show the relationship, the insulated wire 7 is illustrated by a thick line.

By the way, in this wiring operation, the direction of the head portion 13 is the same as the wiring direction of the insulated wire 7 and the head portion 13.
The plate surfaces 21c and 22b are always set to be parallel. The wiring operation is performed by the relative movement between the head unit 13 and the wiring plate 14 at a position where the lower surface of the head unit 13 and the upper surface of the wiring plate 14 are close to each other.

First, the wiring operation of the insulated wire 7 is started from a starting point S shown in FIG. The starting point S is set at an arbitrary position in the wiring board 14. Then, in the wiring groove 42 from the starting point S to the first bending point P1 of the covered electric wire 7, the covered electric wire 7 projecting from the head portion 13 in advance is wired. At this bending point P1, as shown in FIG. 3B, the pressing pin 32 in the head portion 13 is
Move downward along 5. Then, the covered electric wire 7 is pressed by the pressing pin 32 and is pushed into the wiring groove 42. The head section 13 is rotated by the head rotating mechanism 12 in a direction from the bending point P1 to the bending point P2.

Next, wiring between the bending points P1 and P2 is performed. At this time, the insulated wire 7 is bent at the bending point P1.
Is fixed to the wiring groove 42 by frictional resistance with the partition wall 41 in the above. Therefore, when the head portion 13 moves in the direction of the bending point P2, the insulated wire 7 moves to the bending point P2.
It is pulled out from the head part 13 with 1 as a fulcrum. That is, the insulated wire 7 is actively driven by the motor 1 or the like.
3 is not supplied to the wiring board 14, but is wired by being pulled out at the bending point P1.
Thus, the covered electric wire 7 is laid in the wiring groove 42 between the bending points P1 and P2.

Then, the head portion 13 is moved to the bending point P2.
Is reached, the insulated wire 7 is pushed into the wiring groove 42 by the pressing pin 32, similarly to the bending point P1. Further, the head portion 13 is rotated in a direction from the bending point P2 to the bending point P3. Then, like the wiring between the bending points P1 and P2, the bending points P2 and P2
Wiring between 3 is performed. In this way, wiring is sequentially performed to each of the bending points P3 to P14, and finally wiring to the end point E is performed. The end point E is set at an end of the wiring board 14.

Next, a cutting operation for cutting the covered electric wire 7 will be described. As shown in FIGS. 4 and 5, a pair of cutting blades 43 a provided in the cutting machine 43 is in contact with the end surface of the wiring board 14 at the end point E. Each cutting blade 4
3a is formed such that its tip is formed at an acute angle and is slidable with respect to the end face of the wiring board 14 in a state where the tips face each other.

First, the head portion 13 which has reached the end point E by the above-described wiring operation is moved to a position separated from the end point E by extension as shown in FIG. Then, at that position, the pressing pin 32 is moved downward to
Press down. At the same time, the covered electric wire 7 is held and fixed by the holding mechanism 11.

Next, in this state, each cutting blade 43 is connected to the wiring board 1.
4 to make the respective tips come into contact with each other. Then, the covered electric wire 7 is cut at the end point E by the tip of each cutting blade 43. At this time, the covered electric wire 7 is cut in a state of protruding from the lower surface of the head portion 13. When the covered electric wire 7 protruding from the head portion 13 performs the wiring operation again, the starting point S and the first bending point P1
Are wired in the wiring groove 42 between them. Conversely, starting point S
The length of the covered electric wire 7 protruding from the head portion 13 is set according to the length of the wiring groove 42 between the first bending point P1 and the wiring line 42.

The covered electric wires 7 laid in the wiring grooves 42 of the wiring board 14 by the above wiring operation are provided at the bent portions P1 to P1.
At 4, it is pressed by the pressing pin 32. Therefore, the covered electric wire 7 in each of the bent portions P <b> 1 to P <b> 14 is securely wired at the deepest portion of the wiring groove 42. However, as shown in FIG. 5, a straight portion extending from the bent portion to the bent portion, or a cross point CP at which the covered wires 7 overlap each other.
In this case, the covered electric wire 7 may be laid in a state of floating from the deepest portion of the wiring groove 42.

Then, the wiring board 14 having completed the wiring operation and the cutting operation of the coated electric wire 7 is sent to the press machine 8 in order to hold the coated electric wire 7 at the deepest portion of the wiring groove 42 and press operation is performed. (Pressing operation) is performed. Hereinafter, this pressing operation will be described with reference to FIGS.

FIG. 6 is a perspective view of the press die 52.
FIG. 7 is a sectional view of a main part showing a pressing operation. A plurality of pressing pieces 53 are formed on the lower surface of the press die 52. These pressing pieces 53 are formed at locations corresponding to the wiring grooves 42 of the wiring board 14. The width of each pressing piece 53 is
It is formed narrower than the width of the wiring groove 42. The height of each pressing piece 53 is equal to the depth from the upper surface of the partition wall 41 to the covered electric wire 7 in a state where the covered electric wire 7 is laid in the wiring groove 42.

In this press operation, first, the mounting table 5 is moved along the guide rail 4, and the wiring board 14 is arranged at a position corresponding to the press die 52 in the press groove 8. Next, the cylinder 51 is driven by the drive unit 9 to move the press die 52 downward. Then, the lower surface of the press die 52 and the upper surface of the wiring board 14 come close to each other, and each pressing piece 5
3 is inserted into the wiring groove 42.

As a result, as shown in FIG. 7A, the covered electric wire 7 floating from the deepest part of the wiring groove 42 is wired by the pressing piece 53 as shown in FIG. Groove 42
Is pushed to the deepest part.

Hereinafter, the above-described wiring machine 1 and press machine groove 8
The function and effect of the method will be described. ◎ In the above wiring operation, the covered electric wire 7 in the head portion 13 is divided into the partition walls 41 in the bent portions P1 to P14.
It is supplied to the wiring board 14 in a form pulled out from the inside of the head portion 13 by utilizing the frictional resistance between the wire and the covered electric wire 7. Therefore, as shown in FIG.
When pulled out from the inside, the covered electric wire 7 comes into contact with the third guide roller 31. And the covered electric wire 7 is the first to third
It is pulled out while being guided by the guide rollers 29 to 31. A contact portion between the covered electric wire 7 and each of the guide rollers 29 to 31 is provided with a covered electric wire 7 generated by drawing out the covered electric wire 7.
Stress is applied. In this state, the stress is most concentrated on the contact portion between the covered electric wire 7 and the third guide roller 31. At this time, since each of the guide rollers 29 to 31 is rotatable, it rotates in accordance with the movement of the covered electric wire 7.
That is, each of the guide rollers 29 to 31 guides the covered electric wire 7 while sliding and rotating with the covered electric wire 7. Therefore,
The wiring machine 1 can supply the coated electric wire 7 to the wiring plate 14 in a state where the frictional resistance of each of the guide rollers 29 to 31 is as small as possible. As a result, the head 13 and the wiring board 14
Is applied to the insulated wire 7,
At the bending points P1 to P14 of the insulated wire 7, it is possible to prevent the insulated wire 7 from being damaged or the insulated wire 7 from being disconnected, and to reliably supply the insulated wire 7 to the wiring board 14.

The wiring of the insulated wire 7 is performed from the starting point S, and the partition wall 41 and the insulated wire 7 at the bending point P1 are
From the inside of the head portion 13 using the frictional resistance of
Is pulled out. Therefore, there is no need to provide a gripping mechanism for extracting an electric wire as described in the related art. Therefore, the number of parts of the wiring machine 1 can be reduced.

When the wiring operation is not performed, the covered electric wire 7 is always held and fixed by the holding mechanism 11. Therefore, the covered electric wire 7 can be reliably held in the head portion 13.

The covered electric wire 7 laid in the wiring groove 42 of the wiring board 14 is pressed by the pressing pin 32 at each of the bent portions P1 to P14. Therefore, each bent portion P1 to P1
4 is securely wired at the deepest part of the wiring groove 42. Therefore, when laying the insulated wire 7,
In each of the bent portions P1 to P14, the insulated wire 7 is
2 can be securely wired.

The insulated wire 7 that has reached the end point E in the wiring operation is cut at the end point E in the cutting operation. The covered electric wire 7 is cut in a state of protruding from the lower surface of the head portion 13. Then, when performing the next wiring operation, the protruding portion is applied to the wiring between the starting point S and the bending point P1. Therefore, when performing the next wiring operation, the covered electric wire 7 is used thoroughly between the wiring operation and the wiring operation. Therefore, between the wiring operation and the wiring operation, an unnecessary portion does not occur in the covered electric wire 7. As a result, the covered electric wire 7 can be rationally laid, and the manufacturing cost can be reduced. The following wiring operation is performed when the same wiring board 14 is wired with a different wiring pattern, or when the different wiring boards 14 are coated with the same wiring pattern. This is when performing the wiring operation of the electric wire 7 or performing the wiring operation of the covered electric wire 7 with different wiring patterns on different wiring boards 14.

In the cutting operation, the covered electric wire 7 in the head portion 13 is cut while being pressed downward by the pressing pin 32. Therefore, the insulated wire 7 is not cut off in a floating state. Therefore, the cutting blade 43 does not impair the cutting of the coated electric wire 7 and can perform a reliable cutting. Further, since the insulated wire 7 is pressed by the pressing pin 32, the insulated wire 7 does not float from the wiring groove 42 at the end point E. Therefore, at the end point E, the covered electric wire 7 can be reliably held in the wiring groove 42.

A servo motor (not shown) is built in the support shaft 2b and the head rotation mechanism 12 of the robot 2. Therefore, the amount of movement of the drive shaft 2c in the horizontal or vertical direction and the amount of rotation of the head 13 can be precisely controlled.

When the laid covered electric wire 7 is laid in a state of floating in the wiring groove 42, the covered electric wire 7 is laid on the same wiring board 14 in a different wiring pattern. In this case, a portion where the wiring pattern overlaps with the wiring pattern on which the wiring was performed first (such as a cross point CP shown in FIG. 5).
When the occurrence of the problem occurs, there is a possibility that the covered electric wire 7 to which the wiring has been performed later falls out of the wiring groove 42 and fails to perform the wiring. However, in the above-described embodiment, the insulated wire 7 laid first is
Is securely held at the deepest part of the wiring groove 42 by the press machine 8. Therefore, even when the covered electric wires 7 are laid over the covered electric wires 7, the covered electric wires 7 laid one upon another can be reliably held in the wiring grooves 42. Therefore, reliable multiple wiring on the same wiring board 14 is possible, and high density of the conductive circuit can be realized.

The wiring operation by the wiring machine 1 and the pressing operation by the press machine 8 are performed in a series of steps. for that reason,
Manufacturing TAT (Turn Around Time) can be shortened. The above embodiment may be modified as follows.
Even in that case, the same operation and effect can be obtained.

The first and second roller support shafts 26 and 27 and the first and second guide rollers 29 and 30 provided inside the head portion 13 are omitted. That is, only the third roller support shaft 28 and the third guide roller 31 are provided.

As described above, when the insulated wire 7 is wired, the insulated wire 7 inside the head 13 is
It comes into contact with the guide rollers 29 to 31. Then, a stress from the covered electric wire 7 generated by drawing out the covered electric wire 7 is applied to the contact portion. In this state, the stress is most concentrated on the contact portion between the insulated wire 7 and the guide roller 31. Therefore, almost no stress from the insulated wire 7 occurs at the contact portions between the insulated wire 7 and the first and second guide rollers 29 and 30 that occur when the insulated wire 7 is pulled out from the head portion 13. Therefore, even if the first and second guide rollers 29 and 30 are omitted, the bending point P of the insulated wire 7
It is possible to substantially prevent the covered electric wire 7 from being damaged or disconnected from 1 to P14. In this case, it is desirable to provide a guide wall for the covered electric wire 7 instead of the first and second roller support shafts 26 and 27.

One of the first roller support shaft 26 and the first guide roller 29 and the second roller support shaft 27 and the second guide roller 30 provided inside the head portion 13 is omitted. Even in this case, the bending point P1 of the insulated wire 7
It is possible to prevent the covered electric wire 7 from being damaged or broken from P14 to a considerable extent.

In the above embodiment, the pressing pin 32 presses the insulated wire 7 only at each of the bent portions P1 to P14 and the end point E of the wiring board 14, but in addition to this, the insulated wire 7 is The insulated wire 7 is pressed at a place where it is easy to float from the groove 42. In this manner, when there is a portion where the covered electric wire 7 is likely to float from the wiring groove 42, it is possible to prevent the wiring from failing at that portion.

In the above embodiment, the pressing machine 8
The covered electric wire 7 is pushed into the deepest part of the wiring groove 42. The depth of pushing the coated electric wire 7 into the wiring groove 42 is the depth of the wiring groove 4.
The depth is not limited to the deepest part and may be set to a predetermined depth in advance.

In the above-described embodiment, the covered wire 7 is laid directly on the laying plate 14, but first, the dies having the laying pattern formed by the laying grooves are laid, and thereafter, The covered electric wire may be transferred from the mold to the wiring board.

In the above embodiment, the conductive circuit is constituted by the insulated wire 7, but the conductive circuit may be constituted by the bare wire. Although the embodiments have been described above, technical ideas other than the claims that can be grasped from the embodiments will be described below along with their effects.
