Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cover board and a wiring board.
[0002]
[Prior art]
The computerization of the vehicle equipment is remarkable, and the wire harness routed in the vehicle is also a large one having complicated branch lines. Therefore, when manufacturing a wire harness, a construction method is generally adopted in which the wire harness is divided into several sub-assemblies and each sub-assembly is gloss-assembled on the main line wiring board. As a procedure for assembling such a wire harness, conventionally, a method called a small sub construction method and a method called a medium sub construction method have been adopted.
[0003]
In the so-called small sub-construction method, a terminal connected to the end of an electric wire is inserted into a connector, thereby connecting several sub-assemblies, and a plurality of manufactured sub-assemblies are connected to a main-line wiring board. A wiring process for wiring up and a gloss assembling process for forming a wire group of the final wire harness by binding a plurality of arranged subassemblies together.
[0004]
The so-called medium sub-construction method includes a step of manufacturing an intermediate assembly by combining some of the above sub-assemblies, and then gloss-assembling the intermediate assembly (see Japanese Patent Application Laid-Open No. 8-235934).
[0005]
By the way, in any of the above methods, unless the manufactured sub-assembly is adapted to the form at the time of the gloss assembly, the operation flow line is complicated at the time of the gloss assembly, and a wasteful work is generated.
[0006]
Therefore, in the conventional construction method, in any case, the subassembly is routed and manufactured in the same form as that at the time of the gloss assembly.
[0007]
[Problems to be solved by the invention]
Recently, combined with the digitization of vehicle wire harnesses, it has been required to manufacture large-sized subassemblies having, for example, 80 to 100 circuits having complicated branch lines. In particular, it is preferable to manufacture such a subassembly having a large number of circuits at a time in order to reduce terminals not inserted into the connector (hereinafter referred to as “rose terminals”).
[0008]
However, when a large-sized subassembly is manufactured all at once, it becomes difficult to transfer a subassembly in which a plurality of electric wires are assembled onto the wiring board, and the subassembly transfer process (from the subassembly line to the main line) becomes difficult. Transport) was very time-consuming.
[0009]
In particular, the wiring board is provided with a large number of electric wire holders for routing the sub-assemblies. This holding tool is, for example, a standing member that is erected on the wiring board as a wire holding member made of a bar bent into a U-shape, and is disposed over the entire surface of the wiring board in various directions. Therefore, there is a problem that the larger the sub-assembly, the more easily the electric wire constituting the sub-assembly becomes caught and the workability is deteriorated. In this respect, if the entanglement between the wires occurs even at one place, the gloss assembly cannot be performed. Therefore, the handling of the form of the subassembly in the subassembly delivery process is very important.
[0010]
The present invention has been made in view of the above problems, and it is an object of the present invention to provide a cover board and a wiring board capable of easily arranging a large-sized subassembly on a wiring board of a main line. Yes.
[0011]
[Means for Solving the Problems]

[0012]
In this invention, by attaching the cover board to the wiring board and covering a part of the electric wire holder, the wiring work is performed while receiving the electric wires of the sub-assembly routed on the wiring board on the cover board. Therefore, even if the sub-assembly is large, the electric wire that is a component of the sub-assembly becomes difficult to be caught by the electric wire holder, and the routing work can be performed remarkably efficiently. As a material for the cover board, a material such as urethane that is relatively light and easy to process is preferable. In this case, not only handling becomes very easy, but also processing into a desired shape becomes easy.
[0013]
In a particularly preferable aspect, an opening portion is provided for opening an electric wire holder necessary for routing the subassembly along one direction.
[0014]
In this way, even when a long subassembly is routed from one end to the other, there is no need for the operator to go back and forth, and the subassembly can be routed with simple flow lines. It can be carried out.
[0015]
Another aspect of the present invention is a wiring board in which a large number of electric wire holders for standing up a subassembly in which a plurality of electric wires are assembled in advance are installed,
The above cover board;
An attachment member for attaching the cover board to the wiring board body so that the cover board can be displaced between a cover posture that covers the part of the electric wire holders and an open posture that opens all the electric wire holders;
It is the wiring board characterized by providing.
[0016]
In the present invention, since the sub-assembly wiring work is facilitated only by providing a cover board having a simple structure, it is possible to significantly improve the work efficiency at a low equipment cost.
[0017]
In a preferred embodiment of the wiring board, the wiring board further includes a holding member for holding the cover board in the cover posture.
[0018]
In this case, the cover board is attached to each wiring board by the holding member, and handling of the attached cover board is facilitated. Therefore, even if the wiring board is of a transport type that is transported by the conveyor, Thus, it is possible to construct a line in which the subassembly can be easily routed.
[0019]

Then, the sub-assembly M is connected by the terminal insertion support unit 210 provided on the board 201 by circling a plurality of stations set along the rail 103. In FIG. 2, 111b is an elastic stopper.
[0026]
The connector holder 211 has a substantially rectangular parallelepiped outer shell, and has a bottomed connector housing portion 212 that opens according to the outer shape of the target connector C on the upper surface thereof. The connector holder 211 is set in various shapes corresponding to the number of poles and the shape of the connector C to be held. A plurality of the connector holders 211 are laid out so that the connectors corresponding to the connector accommodating portions 212 of the respective connector holders 211 are accommodated, and one end of the terminal-attached electric wire W (see FIG. 8) is connected to one connector. This is because after connecting to the connector mounted on the holder 211, the other end of the terminal-attached electric wire W is connected to a connector mounted on another connector holder 211 in the state as it is. A probe holding plate (not shown) is fixed to the bottom of the connector housing portion 212 of each connector holder 211, and a mounting surface for receiving the bottom portion of the connector C housed in the connector housing portion 212 by the probe holding plate. The probe 220 is held while being formed. The probes 220 are provided in a one-to-one correspondence with the connector poles (terminal accommodating portions) held by the connector holders 211, and each probe 220 is accommodated when the connector C is accommodated in the connector accommodating portion 212. Is inserted into the terminal accommodating chamber of the connector C, and is connected to the terminal of the terminal-equipped electric wire W by connecting the end of the terminal-equipped electric wire W to the terminal accommodating chamber. .
[0027]
The terminal insertion support unit 210 described above has an interface connector 250, and is electrically connected to an electric wire connection instruction device (not shown) arranged at each station via the interface connector 250, and is required. The instruction to connect the sub-assembly M is made by the display lamp 240 provided in the connector holder 211.
[0028]
In the illustrated embodiment, the terminal insertion support units 210 are grouped from the viewpoint described below.
[0029]
As shown in FIG. 1, the terminal insertion support unit 210 erected on the board 201 of the drawing board unit B is provided for each branch line when the subassembly M is routed on the wiring board 11 of the main line ML. Are arranged in a state classified as a group G indicated by (1) to (5).
[0030]
These groups G are based on work procedures when performing gloss assembly.
[0031]
That is, when the wiring board 11 of the main line ML moves in the conveyor conveyance direction indicated by the arrow AW1, for example, if the work is performed along the direction AW2 opposite to the conveyance direction AW1 of the wiring board 11 of the main line ML, The worker can perform each work efficiently while remaining almost stationary at a fixed position. Therefore, in the example shown in the figure, the work area that the worker performs on the wiring board 11 of the main line ML is divided into branch lines from the upstream side in the transport direction AW1 of the conveyor to correspond to the connectors in the corresponding group G. The terminal insertion support units 210 to be arranged are arranged from the left to the right in the drawing. The means for identifying the grouping is realized by color-coding each terminal insertion support unit 210 for each group G, or by marking a partition line or the like for each group G on the board 201.
[0032]
In addition, in the example of illustration, what differs in the process in a post process, such as a connection connector for connecting wire harnesses, is classified as another group F.
[0033]
In this way, in the illustrated embodiment, the final form of the subassembly M can be made to be a compressed form by categorizing and laying out the connectors C for each branch line, so that a large-sized subassembly M is manufactured. However, by laying out the connectors C densely, it is possible to perform the connection work of the subassembly M in a compact work area. Therefore, workability is improved.
[0034]
Next, the transfer tool 500 for transferring the subassembly M manufactured on the board of the drawing board unit B to the wiring board 11 will be described.
[0035]
FIG. 3 is a perspective view showing a mounting structure of the delivery tool 500. FIG. 4 is a perspective view showing a schematic configuration of the transfer device 500 of the subassembly according to the present embodiment, FIG. 5 is a front view of the transfer device 500, and FIG. ) Describes the rail body. FIG. 6 is a perspective view showing the operation of the delivery tool 500. FIG. 7 is a perspective view showing a main part of the delivery tool according to the present embodiment. FIG. 8 is a schematic plan view schematically showing a temporary holding state of the subassembly M according to the present embodiment, where (A) shows a wiring state before temporary holding, and (B) shows a temporary holding state. .
[0036]
As shown in FIG. 2 and FIGS. 3 to 8, the drawing unit B is provided with a delivery tool 500 for temporarily holding the electric wires W for each group G. The delivery tool 500 has a rail body 501 as a carrier and an elastic clamp 510 as a temporary holding member standing on the rail body 501, and the elastic clamp 510 is assigned to the drawing board unit B. A plurality are provided corresponding to the group G.
[0037]
As shown in FIG. 3, the elastic clamp 510 has a pair of clamp pieces 511 attached to the case 512 so as to be freely opened and closed, and further provided with an elastic piece 513 attached to the case 512 for each clamp piece 511. It was energized to. Then, after the process of connecting the electric wire W to the connector C is completed, if the temporary holding is performed by the elastic clamp 510, the taping work becomes unnecessary.
[0038]
Further, as shown in FIG. 3, the delivery tool 500 is detachably provided on the drawing board unit B by a detachable holder 550. The detachable holder 550 slides between a bracket 552 having a locking claw 551, and a holding posture in which the delivery device 500 is held in cooperation with the bracket 552 and the opening claw 551 in cooperation with the locking claw 551. A slide claw 553 and an X-shaped plate spring 554 for biasing the slide claw 553 to a clamping posture are provided, and a plurality of the brackets 552 are arranged at appropriate positions on the above-mentioned drawing unit B. The delivery tool 500 can be attached and detached.
[0039]
Next, referring to FIGS. 4 to 6, the elastic clamps 510 are connected by a connecting mechanism 520.
[0040]
This connecting mechanism 520 is cantilevered on one side of the elastic clamp 510 and extends in parallel with the rail body 501, a slider 522 attached to the rod 521 so as to reciprocate, and a slider 522. A rigid wire 523 that is fixed to one side of the rod and extends in parallel with the rod 521, and is fixed to an end of the rod 521 and connected to the rigid wire 523 so as to be reciprocally movable. A stopper slider 524, a connecting slider 525 fixed to the end of the rigid wire 523 and guided so as to reciprocate within the rail body 501, and a next elastic clamp 510 facing one side of the connecting slider 525 On the other hand, a wire 526 for connecting the connection slider 525 is provided, and the above-described pattern is repeated.
[0041]
In the illustrated embodiment, each of the sliders 522, 524, and 525 is embodied by the same type of slide member that can reciprocate along the longitudinal direction of the rail body 501, and more specifically, the slide of the curtain rail. It is possible to divert runners. In the illustrated example, as shown in FIG. 7, each of the sliders 522, 524, and 525 is reciprocated by rotatably mounting a sleeve R 2 on the core R 1 and rolling the sleeve R 2 in the rail body 501. It is configured to be movable. In the illustrated example, the same type of slider 527 is also provided below the elastic clamp 510.
[0042]
If this configuration is adopted, the slider 522 is displaced along the rod 521 between the corresponding elastic clamp 510 and the stopper slider 524 integrated with the elastic clamp 510, as shown in FIG. At the same time, the force at the time of displacement can be transmitted to the elastic clamp 510 by contacting the elastic clamp 510 or the stopper slider 524. Further, since the connecting slider 525 integrated with the slider 522 via the rigid wire 523 is connected to another elastic clamp 510 via the wire 526, the other elastic clamp 510 is connected to the one elastic clamp. When separated from 510, the one elastic clamp 510 can be interlocked via the wire 526, the connecting slider 525, the rigid wire 523, the slider 522, and the stopper slider 524.
[0043]
In the illustrated embodiment, since one elastic clamp 510 and another elastic clamp 510 are connected via a flexible wire 526, relative displacement of both elastic clamps 510 and 510 is allowed. However, when the two elastic clamps 510 and 510 are interlocked, a simple and inexpensive configuration can be obtained.
[0044]
Next, referring to FIG. 1 and FIG. 7, the rail body 501 mainly includes an outer rail 501a formed in a channel shape and an inner rail 501b slidably mounted in the outer rail 501a. Yes.
[0045]
The assembly AS of the elastic clamps 510, 510,... And the coupling mechanism 520 is accommodated in the rails 501a and 501b, and the sliders 527 of the elastic clamps 510 and 510 corresponding to both end portions of the assembly AS are as follows. The rails 501a and 501b are respectively fixed to the corresponding ends. As a result, the rails 501a and 501b are allowed to be displaced relative to each other, but are separated from each other by the maximum extension length of the assembly AS. By adopting such a structure, as shown in FIGS. 1 and 2, the board unit B is mounted on the board 201 in a reduced state in which the inner rail 501b is accommodated in the outer rail 501a. The sub-assembly M connected above can be temporarily held (see FIGS. 8A and 8B), and after temporary holding, the transfer tool 500 is removed from the board 201 and the rail body 501 is removed. When laying on the wiring board 11 of the main line ML, the sub-assembly M temporarily held by the transfer tool 500 is extended corresponding to the width dimension of the wiring board 11 and deployed on the wiring board 11. Can be routed while.
[0046]
Next, the delivery process of the subassembly M in the main line ML will be described with reference to FIG. 9A and 9B are side views of the wiring board 11 employed in the main line ML. FIG. 9A shows a state during wiring, and FIG. 9B shows a state after wiring. 10 to 15 are perspective views showing a delivery process.
[0047]
First, referring to FIGS. 9A and 9B and FIG. 10, the wiring board 11 is composed of a plate material that is inclined so that the operator side is lowered, as is well known. The wiring board 11 is provided with a large number of electric wire holders 11a for supporting the sub-assembly M (which will eventually become a wire harness) in a predetermined order. By routing the assembly M, the sub-assembly M can be arranged in a final routing configuration.
[0048]
As schematically shown in FIG. 1, the subassembly M according to the present embodiment has a tree-like form in which a plurality of branch lines grouped by (1) to (5) from the trunk line M1 branch. Each electric wire holder 11a is also arranged according to this branching mode.
[0049]
In the illustrated embodiment, as shown by the phantom lines in FIG. 9 (A), a pair of pillars 81 (stands up) are provided at a position above the main line layout position where the main line M1 is laid out. A hook 82 (detachable tool) is formed on the top of the pillar 81. And the delivery tool 500 mentioned above is hold | maintained on the wiring board 11 by latching to the hook 82 provided in this pillar 81 (refer FIG. 11 and FIG. 12).
[0050]
Further, in the illustrated embodiment, a cover board 85 is provided with a wire 85a for each wiring board 11 in order to prevent the sub-assembly M hanging from the delivery device 500 locked to the hook 82 from being caught on the wire holder 11a. It is attached so that it can be suspended. The cover board 85 covers a part of the electric wire holder 11a so as to receive the sub-assembly M arranged on the wiring board 11 by being detachably disposed on the wiring board 11. Yes, as shown in FIGS. 10 to 14, it can be displaced between a cover posture that covers the part of the electric wire holders 11 a and an open posture that opens all the electric wire holders 11 a as shown in FIG. 15. Thus, it is suspended by the wire 85a as an attachment member.
[0051]
The cover board 85 is preferably made of a material that is relatively light and easy to process, such as urethane. In this case, not only handling becomes very easy, but also processing into a desired shape becomes easy.
[0052]
In the illustrated example, a pair of hooks 86 are provided on the upper edge of the cover board 85, and the hooks 86 are locked to a predetermined holder 87 erected on the wiring board 11. It is possible to hold the cover in the above posture and position it with respect to each holding tool 11a. In the illustrated example, the holder 87 is a part of the holder 11a. However, the holder 87 is not limited to this, and the holder 87 may be configured by a dedicated hook or the like.
[0053]
Further, the cover board 85 is provided with a notch 88 at a predetermined location, and the notch 88 exposes a part of the electric wire holder 11a disposed below the main line layout position. Thereby, in the delivery process described below, the operator can efficiently perform the delivery work along the direction AW2 opposite to the conveyance direction AW1 of the wiring board 11 of the main line ML.
[0054]
Next, the delivery process to this wiring board 11 is demonstrated.
[0055]
In the above configuration, as shown in FIG. 10, first, the cover board 85 suspended from the wiring board 11 is placed at a predetermined position of the wiring board 11, and the hook 86 is attached to the holder 87 on the wiring board 11. Lock to. Next, as shown in FIG. 11, the delivery tool 500 that temporarily holds the sub-assembly M is locked to a hook 82 provided on the pillar 81 on the wiring board 11. At this stage, since the delivery tool 500 is in a contracted state corresponding to the longitudinal dimension of the drawing board unit B, as a work procedure, first of the pair of pillars 81, the downstream side in the transport direction AW1 of the wiring board 11 is used. The end of the delivery tool 500 is locked to the object.
[0056]
Next, as shown in FIG. 12, the rail body 501 of the delivery tool 500 is extended, and the other end is locked to a hook 82 provided on the pillar 81 on the upstream side in the transport direction AW1 of the wiring board 11. In this extension operation, the rail body 501 can be extended in a state where the elastic clamp 510 fixed to the corresponding end portion of the transfer tool 500 is engaged with the hook 82 on the downstream side in the transport direction AW1, so that the extension can be easily performed. Work can be done. By this extension operation, the subassembly M held in a compressed state is expanded while maintaining its routing form (a state classified and grouped for each branch line).
[0057]
Then, as shown in FIG. 13 and FIG. 14, the branch line is removed from the elastic clamp 510 of the delivery tool 500 in order from the downstream side in the transport direction AW1 of the wiring board 11, and routed on the corresponding wire holder 11a. As a result, the sub-assembly M can be easily routed on the wiring board 11. In this routing work, since the subassembly M is hung on the cover board 85, the problem that the electric wire W of the subassembly M is caught by the holder 11a is avoided as much as possible. Further, in the illustrated embodiment, a notch 88 is provided at a predetermined position of the cover board 85, and the wiring work can be performed on the holder 11a exposed from the notch 88. 11 can be executed smoothly in order from the downstream side in the transport direction AW1.
[0058]
Then, after the wiring work of the group G not covered with the cover board 85 is completed, the cover board 85 is lowered from the wiring board 11 and lowered from the trunk line M1 as shown in FIG. 9B and FIG. After all the routing operations have been completed, the delivery tool 500 may be removed.
[0059]
As described above, according to the present embodiment, the cover board 85 is attached to the wiring board 11 to cover a part of the electric wire holder 11a, so that the sub-assembly M routed on the wiring board 11 is covered. Since the wiring work can be performed while receiving the terminal-attached electric wire W on the cover board 85, even if the sub-assembly M is large, the terminal-attached electric wire W, which is a constituent element, is caught by the electric wire holder 11a. It becomes difficult, and the routing work can be performed remarkably efficiently.
[0060]
In particular, in the illustrated embodiment, a notch 88 is provided as an opening for opening the electric wire holder 11a necessary for routing the subassembly M along one direction, so that the long subassembly M is provided. When routing the cable from one end side to the other end side (in the illustrated example, in the direction of the work process AW2), the flow line of the operator does not go back and forth, and the sub assembly M is routed with a simple flow line. Work can be done.
[0061]
Moreover, in the wiring board 11 of this embodiment, the installation work of the subassembly M becomes easy only by providing the cover board 85 having a simple configuration, so that the work efficiency can be greatly improved at a low equipment cost. Is possible.
[0062]
In the present embodiment, a hook 86 and a holding tool 87 are further provided as holding members for holding the cover board 85 in the cover posture (see FIGS. 10 to 14). As a result of the cover board 85 being attached to each wiring board 11 and the handling of the attached cover board 85 being facilitated, the wiring board 11 can be transported by a conveyor as described above. Thus, it is possible to construct a line in which the subassembly M can be easily routed.
[0063]
Therefore, according to the above-described embodiment, even if the subassembly M is large, the electric wire W that is a component thereof is not easily caught by the electric wire holder 11a, and the wiring work can be performed remarkably efficiently. The large sub-assembly M can be easily routed on the wiring board 11 of the main line ML.
[0064]
The above-described embodiment is merely a preferred specific example of the present invention, and the present invention is not limited to the above-described embodiment.
[0065]
For example, the present invention can be applied to a wiring board that is not in the form of a conveyor.
[0066]
In addition, it goes without saying that various design changes are possible within the scope of the claims of the present invention.
[0067]
【The invention's effect】
As described above, according to the present invention, even if the subassembly is large, the electric wire that is a constituent element thereof is not easily caught by the electric wire holder, and the wiring work can be performed remarkably efficiently. The large sub-assembly can be easily routed on the main line wiring board.
