[Details of Embodiments of the present disclosure]
Specific examples of the wiring members of the present disclosure will be described below with reference to the drawings. It should be noted that the present invention is not limited to these examples, and is indicated by the scope of claims, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.

[Embodiment 1]
Hereinafter, the wiring member according to the first embodiment will be described. FIG. 1 is a plan view showing the wiring member 10 according to the first embodiment. FIG. 2 is a cross-sectional view taken along the line II-II of FIG. In order to distinguish the contour of the base member 26 from the pattern 30 in FIG. 1, the contour of the base member 26 is shown by a solid line, and the pattern 30 is shown by a two-dot chain line.

The wiring member 10 includes a flat wiring body 20 and a pattern 30 provided on the flat wiring body 20.

The flat wiring body 20 is a member mounted on a vehicle to supply electric power to each device of the vehicle and to send and receive signals. The flat wiring body 20 is a wiring body formed so that the dimension in the thickness direction is smaller than the dimension in the plane direction orthogonal to the thickness direction. The flat wiring body 20 includes a plurality of linear transmission members 22 and a base member 26 that holds the plurality of linear transmission members 22 flat.

The linear transmission member 22 may be any linear member that transmits electricity, light, or the like. For example, the linear transmission member 22 may be a general electric wire having a core wire and a coating 24 around the core wire, or may be a bare wire, a shielded wire, an enamel wire, a nichrome wire, an optical fiber, or the like.

The linear transmission member 22 for transmitting electricity may be various signal lines or various power lines. The linear transmission member 22 for transmitting electricity may be used as an antenna, a coil, or the like that sends a signal or electric power to or receives a signal from the space.

In the example shown in FIG. 2, the linear transmission member 22 includes a transmission line main body 23 that transmits electricity, light, or the like, and a coating 24 that covers the transmission line main body 23. When the linear transmission member 22 is a general electric wire, the transmission line main body 23 is a core wire and the coating 24 is an insulating coating. Further, in the example shown in FIG. 2, a plurality of linear transmission members 22 having the same diameter and structure are arranged on one base member 26, but the diameters, structures, etc. of the plurality of linear transmission members 22 are appropriately set. The linear transmission members 22 having different diameters, structures, etc. may be arranged on the same base member 26.

Further, the linear transmission member 22 may be a single linear object, or a composite of a plurality of linear objects (twisted wire, a cable obtained by collecting a plurality of linear objects and covering them with a sheath, or the like. ) May be. Terminals, connectors C, and the like are appropriately provided at the ends of the linear transmission member 22 according to the connection form between the linear transmission member 22 and the mating member.

The base member 26 keeps the plurality of linear transmission members 22 flat. The base member 26 is a member that holds the linear transmission member 22 in a two-dimensionally positioned state. The base member 26 includes a seat member 27 and a cover 28.

A linear transmission member 22 is arranged on one main surface of the sheet member 27. The sheet member 27 holds a plurality of linear transmission members 22 in an arranged state. The sheet member 27 may be a member having a rigidity sufficient to hold the plurality of linear transmission members 22 in a plane-positioned state while being curved, or the sheet member 27 may be a member having a plurality of linear shapes while being maintained in a flat state. The member may be rigid enough to hold the transmission member 22 in a two-dimensionally positioned state. The sheet member 27 may have a three-dimensional shape portion such that a wall is partially erected. Here, the seat member 27 will be described as a bendable member.

The material constituting the sheet member 27 is not particularly limited, but the sheet member 27 is formed of a material containing a resin such as PVC (polyvinyl chloride), PET (polyethylene terephthalate), PP (polypropylene), and the like. .. The sheet member 27 may be a fibrous material having fibers such as a non-woven fabric, a woven fabric, or a knitted fabric, or may be a non-fiber material. The non-fiber material may be a solid member whose inside is uniformly buried, or a foam in which a resin is foam-molded. The sheet member 27 may also contain a material such as metal.

The sheet member 27 may be a single layer or may be laminated in a plurality of layers. When a plurality of layers are laminated, for example, it is conceivable that the resin layer and the resin layer are laminated. Further, for example, it is conceivable that the resin layer and the metal layer are laminated. Further, the sheet member 27 may be a non-fiber material layer and a non-fiber material layer overlapped, a non-fiber material layer and a fibrous material layer may be overlapped, or a fiber. The material layer and the fiber material layer may be overlapped.

The linear transmission member 22 is fixed to the sheet member 27 on the main surface of the sheet member 27 in a state of being arranged along a predetermined path. The sheet member 27 is formed in a strip shape extending along the path of the linear transmission member 22. The path of the linear transmission member 22 on the sheet member 27 may be appropriately set, and the linear transmission member 22 may be arranged linearly on the sheet member 27 or may be arranged bent. You may be. When the linear transmission member 22 is bent and arranged on the sheet member 27, the sheet member 27 may also be bent and formed. The plurality of linear transmission members 22 may be arranged on different routes so as to branch or intersect on the sheet member 27. In this case, the seat member 27 may also be formed so as to branch or intersect. By forming the sheet member 27 in a shape along the paths of the plurality of linear transmission members 22, it is possible to suppress interference between the sheet member 27 and other parts, reduce the weight, and the like. Here, the sheet member 27 is formed in an F shape, that is, in a shape in which the band-shaped portions 27b and 27c extend from the end portion and the intermediate portion of the strip-shaped portion 27a, respectively.

The linear transmission member 22 and the sheet member 27 are fixed. As such a fixing mode, the contact site may be fixed, the non-contact site may be fixed, or both may be used in combination. Here, the contact portion fixing means that the portion where the linear transmission member 22 and the sheet member 27 are in contact with each other is attached and fixed. Further, the non-contact site fixing is a fixing mode in which the contact site is not fixed. For example, a sewing thread, another sheet member 27, an adhesive tape or the like presses the linear transmission member 22 toward the sheet member 27, or a sewing thread, another sheet member 27, an adhesive tape or the like presses the linear transmission member 22 toward the sheet member 27. The linear transmission member 22 and the sheet member 27 are sandwiched between the linear transmission member 22 and the sheet member 27 in a state of surrounding the sheet member 27, and the linear transmission member 22 and the sheet member 27 are maintained in a fixed state. Hereinafter, the linear transmission member 22 and the sheet member 27 will be described as being in a state where the contact portion is fixed. Each description of contact site fixation is also applicable to non-contact site fixation, unless the configuration is not applicable.

As the mode of fixing the contact site, indirect fixing may be performed, direct fixing may be performed, or both may be used in combination in different regions. Here, indirect fixing means that the linear transmission member 22 and the sheet member 27 are indirectly attached and fixed via an intervening member such as an adhesive, an adhesive, a double-sided adhesive tape, or a hook-and-loop fastener provided between them. Is what you are doing. Further, the direct fixing means that the linear transmission member 22 and the sheet member 27 are directly attached and fixed without using an adhesive or the like separately provided. In the direct fixing, for example, it is conceivable that the resin contained in at least one of the linear transmission member 22 and the sheet member 27 is melted to be stuck and fixed. Hereinafter, the linear transmission member 22 and the sheet member 27 will be described as being in a directly fixed state. Each description of direct fixation is also applicable to indirect fixation unless the configuration is not applicable.

In forming such a directly fixed state, the resin may be melted by heat, for example, or may be melted by a solvent. That is, the state of direct fixing may be a state of direct fixing by heat or a state of direct fixing by a solvent. It is preferable that the state is directly fixed by heat.

At this time, the means for forming the directly fixed state is not particularly limited, and various means including known means such as welding, fusion, and welding can be used. For example, when a state of direct fixation by heat is formed by welding, various welding means such as ultrasonic welding, heat and pressure welding, hot air welding, and high frequency welding can be adopted. Further, when the directly fixed state is formed by these means, the linear transmission member 22 and the sheet member 27 are brought into the directly fixed state by the means. Specifically, for example, when a directly fixed state is formed by ultrasonic welding, the linear transmission member 22 and the sheet member 27 are brought into a directly fixed state by ultrasonic welding. The portion (fixed portion between the linear transmission member 22 and the sheet member 27) that is directly fixed by heat by welding is the welded part, of which the fixed part by ultrasonic welding is the ultrasonic welded part and heat and pressure welding. The fixed portion formed by the above may be referred to as a heat-pressed welding portion or the like.

In the case of direct fixing, only the resin contained in the coating 24 of the linear transmission member 22 may be melted, or only the resin contained in the sheet member 27 may be melted. In these cases, the melted resin may be attached to the other outer surface, forming a relatively clear interface. Further, in the case of direct fixing, both the resin contained in the coating 24 of the linear transmission member 22 and the resin contained in the sheet member 27 may be melted. In this case, both resins may be mixed to form a clear interface. In particular, when the coating 24 of the linear transmission member 22 and the sheet member 27 contain a resin that is easily compatible with each other, such as the same resin material, both resins may be mixed to form a clear interface.

The cover 28 is fixed to the seat member 27. The cover 28 covers the linear transmission member 22 from the side opposite to the seat member 27. The cover 28 is not fixed to the linear transmission member 22, but may be fixed.

The seat member 27 and the cover 28 are fixed at a portion extending laterally of the linear transmission member 22. As a fixing mode of the sheet member 27 and the cover 28, in the example shown in FIG. 2, direct fixing without using an inclusion such as an adhesive is shown. Of course, the fixing mode of the seat member 27 and the cover 28 is not limited to direct fixing, and various fixing modes described in the fixing mode of the seat member 27 and the linear transmission member 22 can be used.

The same sheet-like member may be used for the sheet member 27 and the cover 28, or different sheet-like members may be used. Here, different sheet-like members are used for the seat member 27 and the cover 28. Here, the sheet-shaped member used for the sheet member 27 is more suitable for fixing to the linear transmission member 22 than the sheet-shaped member used for the cover 28. The sheet-shaped member used for the cover 28 has higher rigidity and is excellent in shape retention than the sheet-shaped member used for the sheet member 27. For example, the sheet member 27 is a first layer formed of the same material as the coating 24 of the linear transmission member 22 to form a solid sheet to which the linear transmission member 22 is fixed, and a first layer formed of a non-woven fabric and overlapping the first layer. It is a member having two layers, and the cover 28 is a member formed in a solid sheet shape by nylon or the like.

The cover 28 is formed in the same shape as the seat member 27 and covers the entire seat member 27. Of course, the cover 28 may be formed in a shape different from that of the seat member 27, or may cover a part of the seat member 27.

The flat wiring body 20 may be formed so as to have rigidity capable of suppressing the end portion from hanging vertically when the intermediate portion is lifted. Here, the flat wiring body 20 is formed so that rigidity is imparted by a cover 28 and a predetermined shape is maintained as much as possible. For example, the shape of the flat wiring body 20 may be maintained in a form arranged on the vehicle or a form close thereto. As a result, it is possible to save the trouble of arranging the flat wiring body 20 when assembling the wiring member 10 to the vehicle.

As shown in FIG. 3, the flat wiring body 20 has a cantilever beam when the intermediate portion is lifted by a robot R or the like, in other words, when the end portion is lifted in a cantilever-like manner. It is preferable that the shaped portion does not hang down, or even if it hangs down, it has a rigidity that allows it to hang down like a beam. As shown in FIG. 3, this bow-shaped sagging method is such that when the flat wiring body 20 in a state where a predetermined portion is lifted and sagging is placed on a platform S wider than the flat wiring body 20, the sagging portion is formed. It is a hanging method in which the hanging portion does not bend inward on the table S and another part does not overlap on the table S, that is, the hanging portion spreads outward on the table S. As a result, it is not necessary to correct the overlap of the end portions after the flat wiring body is carried by the robot R, and the assembling workability can be improved.

The flat wiring body 20 may be formed so as to be foldable for transportation or the like. In the state where the flat wiring body 20 is folded, the bent portion becomes the end portion of the flat wiring body 20. That is, in the folded state, it is preferable that the end portion (bent portion) is formed to have a rigidity capable of suppressing the vertical hanging down when the intermediate portion is lifted. Further, in the state where the flat wiring body 20 formed so as to be foldable is unfolded, the end portion hangs vertically when the portion closer to the foldable portion is lifted on the end side portion than the foldable portion. It is preferable that it is formed so as to have rigidity that can suppress the above.

The pattern 30 is provided so that the three-dimensional posture of the flat wiring body 20 can be recognized. As the pattern 30, a pattern 30 is provided so that the appearance changes when the flat wiring body 20 is bent. In particular, as the pattern 30, a pattern 30 is provided so that the appearance changes when the flat wiring body 20 is bent in the front-back direction. The pattern 30 is provided in the entire area of the base member 26.

In this example, the pattern 30 will be described as being grid lines 30. The grid lines 30 include first and second lines 31, 32 that intersect each other. A plurality of first lines 31 are provided so as to extend in parallel. A plurality of second lines 32 are also provided so as to extend in parallel. Here, the first and second lines 31 and 32 are orthogonal to each other, but may intersect at other angles. Further, here, the first line 31 extends in the same direction as the extending direction of the band-shaped portion 27a, and the second line 32 extends in the same direction as the extending direction of the band-shaped portions 27b and 27c, but the first line 31 , The extending direction of the second line 32 is not limited to this. The first and second lines 31, 32 may extend in a direction intersecting the extending direction of the strips 27a, 27b, 27c.

The color of all grid lines 30 may be the same color. Further, the grid line 30 may include lines having different colors. For example, the color of the first line 31 and the color of the second line 32 can be different from each other. In this case, the first and second lines 31 and 32 can be easily recognized, and the direction of rotation in the plane direction (rotation around the axis extending along the thickness direction) can be set while the wiring member 10 is located at a predetermined position. It becomes easy to recognize. Further, for example, the plurality of first lines 31 may contain lines of different colors, or the plurality of second lines 32 may contain lines of different colors.

The line width and line spacing of the grid lines 30 are not particularly limited. For example, the line width and line spacing of the grid lines 30 may be those that can be recognized in the captured image, and are appropriately set according to the resolution, scale, and the like of the captured image. Further, the line width and the line spacing may be the same for all the grid lines 30, or some parts may be different.

Here, the pattern 30 is attached to the base member 26. The pattern 30 may be formed by attaching a member having a color different from that of the base member 26 to the base member 26, for example. In this case, the single-sided adhesive tape may be attached to the base member 26, the band piece having no adhesive layer may be fused to the base member 26, or attached to the base member 26 with an adhesive, double-sided adhesive tape, or the like. It may be attached, or the paint may be applied to the base member 26 by printing or the like. Further, the pattern 30 may be formed by laser marking. In this case, when the base member 26 is irradiated with the laser beam, the surface of the base member 26 is melted or charred and discolored, and the pattern 30 is formed.

When the base member 26 includes the seat member 27 and the cover 28 as in this example, the pattern 30 may be attached to the seat member 27 or may be attached to the cover 28. For example, when the rigidity of the seat member 27 and the rigidity of the cover 28 are different from each other, the pattern 30 may be applied to the highly rigid member of the seat member 27 and the cover 28. This is because the pattern 30 does not easily collapse.

The pattern 30 is provided at least in the intermediate wiring portion between the connector C and the connector C in the flat wiring body 20. In this example, the pattern 30 is provided close to the position of the connector C. Specifically, the connector C is provided at a position immediately after the linear transmission member 22 extends from the base member 26, and the grid wire 30 is provided up to the edge of the base member 26. However, the edge portion of the connector C may be provided so as to overlap the base member 26, and the pattern 30 may be provided up to the position of the connector C. In this way, when the pattern 30 is provided at or near the position of the connector C, the position of the connector C can be recognized with high accuracy by recognizing the pattern 30. If the position of the connector C can be recognized with high accuracy, it is possible to detect the semi-fitting of the connector C during the assembling operation.

<Method of recognizing wiring members>
Next, a method of recognizing the wiring member 10 using the pattern 30 will be described. Here, it is assumed that the wiring member 10 is recognized by using the pattern 30 when the wiring member 10 is assembled to the vehicle. In particular, here, when the wiring member 10 is automatically assembled to the vehicle, the wiring member 10 will be automatically recognized by using the pattern 30. The wiring member 10 may deviate from a predetermined shape by moving in the packing box during transportation or by bending due to its own weight. By recognizing this deviation using the pattern 30, it is possible to eliminate a work error with respect to a predetermined position on the wiring member 10.

First, the wiring member 10 transported to a predetermined work station is imaged. For example, as shown in FIG. 2, the image pickup apparatus 80 images the flat wiring body 20 from the normal direction (thickness direction). The image pickup apparatus 80 may include a monocular camera or a stereo camera. The pattern 30 may be recognizable by image recognition by a monocular camera from the normal direction. As a result, the configuration of the image pickup apparatus 80 can be simplified. Further, the image pickup device 80 may capture a color image or a monochrome image. When the pattern 30 includes grid lines 30 having different colors, the image pickup apparatus 80 may capture a color image. The image captured by the image pickup device 80 is sent to the processing device 82.

The processing device 82 acquires the distortion in the flat wiring body 20 from the captured image. The processing device 82 includes, for example, a computer including a microprocessor, ROM, RAM, and the like. An arithmetic processing unit such as a microprocessor performs a process of acquiring distortion in the flat wiring body 20 from the state of the pattern 30 in the captured image. For example, the difference between the state of the pattern 30 in the captured image and the state of the pattern 30 in the wiring member 10 in the normal state obtained in advance is obtained, and the strain in the flat wiring body 20 is acquired. The wiring member 10 in the normal state referred to here is a wiring member 10 in a state in which the shape of the flat wiring body 20 is not deviated.

For example, consider the case where an captured image as shown in FIG. 4 is obtained as an captured image. In FIG. 4, the solid line is the grid line 30 obtained in the captured image, and the alternate long and short dash line is the grid line 30 in the wiring member 10 in the normal state. In the example shown in FIG. 4, the grid lines 30 in the wiring member 10 in the normal state extend linearly. On the other hand, the grid line 30 obtained in the captured image has a curved portion extending at a corner portion. In addition, there is a portion where the spacing between the grid lines 30 is also changed. From these changes in the grid lines 30, the distortion of the flat wiring body 20 (here, the degree of bending of the flat wiring body 20 in the front-back direction) can be obtained, and thus the three-dimensional posture of the flat wiring body 20 can be obtained. Can be obtained.

Whether the bend in the flat wiring body 20 is a bend toward the front surface side or a bend toward the back surface side can be recognized by, for example, taking an image with a stereo camera. In addition, it can be recognized by a monocular camera by using a distance measuring sensor.

If the three-dimensional posture of the flat wiring body 20 can be acquired, the robot R or the like can hold a predetermined position on the flat wiring body 20 in a predetermined posture with high accuracy. Further, if the pattern 30 is recognized after the work of fitting the connector C and the three-dimensional posture of the flat wiring body 20 can be acquired, the fitting state of the connector C can be determined. Specifically, when the pattern 30 is formed at or near the position of the connector C, the position, posture, etc. of the connector C can be estimated with high accuracy by recognizing the pattern 30, and the mating state of the connector C is provided. Can be determined.

The arithmetic processing unit such as a microprocessor reads out a computer program including a part or all of the processing for acquiring the distortion in the flat wiring body 20 from the captured image from the storage unit such as ROM and RAM, and executes the program. The computer programs of these plurality of devices can be installed from an external server device or the like. Further, the computer programs of these plurality of devices are distributed in a state of being stored in a recording medium such as a CD-ROM, a DVD-ROM, or a semiconductor memory, respectively.

According to the wiring member 10 as described above, by recognizing the pattern 30 provided on the flat wiring body 20, the action of being able to recognize the three-dimensional posture of the flat wiring body 20 occurs, and the shape of the wiring member 10 is changed. Even if the shape deviates from the predetermined shape, it is possible to recognize the predetermined position on the wiring member 10. Since the pattern 30 is provided in the entire region of the base member 26, the entire flat wiring body 20 can be recognized. Since the pattern 30 is attached to the base member 26, the pattern 30 can be easily formed.

Since the pattern 30 is a grid line 30, the pattern 30 can be easily provided. Since the grid lines 30 include lines having different colors, the rotation direction of the flat wiring body 20 can be recognized.

Since the flat wiring body 20 is formed so as to have rigidity capable of suppressing the end portion from hanging vertically when the intermediate portion is lifted, the shape of the wiring member 10 is less likely to deviate from a predetermined shape.

[Embodiment 2]
The wiring member according to the second embodiment will be described. FIG. 5 is a plan view showing the wiring member 110 according to the second embodiment. Further, FIG. 5 is an enlarged view of a part of the wiring member 110. In the description of the present embodiment, the same reference numerals will be given to the components as described above, and the description thereof will be omitted. The same applies to each of the following embodiments.

In the wiring member 110 in this example, the first pattern portion 34 and the second pattern portion 36, which is finer than the first pattern portion 34, are provided as the pattern 30. As a result, the second pattern portion 36 can be recognized in detail. Here, the distance between the grid lines 30 in the second pattern portion 36 is formed to be narrower than the distance between the grid lines 30 in the first pattern portion 34.

For example, the first pattern portion 34 is formed in a portion of the wiring member 110 that does not need to be recognized in detail. Examples of the portion of the wiring member 110 that does not need to be recognized in detail include an intermediate portion of a portion extending linearly, a portion having high rigidity and the like that is not easily distorted. On the other hand, the second pattern portion 36 is formed in the portion of the wiring member 110 to be recognized in detail. Examples of the portion of the wiring member 110 to be recognized in detail include a branch line portion, a branch portion, and an end portion. Further, as a part to be recognized in detail, there is a part having high accuracy required at the time of assembly work.

In the wiring member 210 in this example, the pattern 30 is provided only in a part of the region of the base member 26. In this case, some patterns 30 can be omitted. Examples of the portion where the pattern 30 can be omitted include a portion that does not need to be recognized during the assembling operation, or a portion where the shape can be estimated with high accuracy by recognizing the portion where the pattern 30 is formed. In addition, for example, in the wiring member 110 according to the second embodiment, the first pattern portion 34 is a portion omitted in this example, and the second pattern portion 36 is a portion in which the pattern 30 in this example is provided. Etc. are also conceivable.

The wiring member according to the fourth embodiment will be described. FIG. 7 is a plan view showing the wiring member 310 according to the fourth embodiment.

In the wiring member 310 in this example, the grid line 30 includes the linear transmission member 22. That is, the linear transmission member 22 is used as the grid line 30. It is not necessary to separately provide the grid line 30 for the portion where the linear transmission member 22 is used as the grid line 30. In the portion where the linear transmission member 22 is used as the grid wire 30, for example, the linear transmission member 22 is not provided and the linear transmission member 22 is exposed, or a transparent cover 28 is provided as the cover 28. It is preferable that the linear transmission member 22 can be recognized. For example, the linear transmission member 22 may be set to a different color from the sheet member 27. Specifically, the linear transmission member 22 and the sheet member 27 may be set to a combination of colors having a large contrast such as black and white.

In the wiring member 310 in this example, the grid line 30 includes a portion where the linear transmission member 22 intersects. As a result, the grid line 30 can be formed only by the linear transmission member 22 at the portion where the linear transmission member 22 intersects. That is, the intersecting linear transmission members 22 can be the first and second lines 31 and 32 of the grid line 30. Of course, one of the first and second lines 31 and 32 of the grid line 30 is the linear transmission member 22, and the other of the first and second lines 31 and 32 of the grid line 30 is the linear transmission member 22. It may be the line 33 separately attached to the base member 26. In this case, a wire 33 attached to the base member 26 may be provided on the linear transmission member 22 so as to cross the linear transmission member 22 separately from the linear transmission member 22.

[Additional Notes]
So far, the pattern 30 has been described as being a grid line 30, but this is not an essential configuration. The pattern 30 may be something other than the grid lines 30. For example, as shown in FIG. 8, the pattern 38 may be a set of dots 39 (dotted portions). As described above, even when the pattern 38 is a set of dots 38, the pattern 30 can be easily provided.

Further, although the flat wiring body 20 has been described as having the linear transmission member 22 fixed on the sheet member 27, this is not an essential configuration. For example, the flat wiring body may be a so-called flexible flat cable that holds a plurality of linear conductors sandwiched between two film materials.

It should be noted that the configurations described in each of the above-described embodiments and modifications can be appropriately combined as long as they do not conflict with each other.
