{Embodiment}
Hereinafter, an electric wire holding jig according to an embodiment and a wire harness assembling apparatus including the same will be described.

<About wire harness>
First, the wire harness 10 to be manufactured will be described. FIG. 1 is an expanded view of an example of the wire harness 10. In FIG. 1, the electric wires 12 passing through the same path are drawn with a single line. For this reason, in FIG. 1, the electric wire 12 drawn with one line may actually be a bundle of a plurality of electric wires 12.

The wire harness 10 to be manufactured has a plurality (four in this case) of connectors 14 connected via a plurality of electric wires 12. More specifically, the wire harness 10 is configured such that a plurality of electric wires 12 are bundled while being branched. And in each branch destination of the wire harness 10, the edge part of the some electric wire 12 is inserted and connected to the connector 14. FIG. In a state where the wire harness 10 is incorporated in the vehicle, each connector 14 is connected to various electrical components mounted on the vehicle. Thereby, the wire harness 10 plays the role which electrically connects the various electrical components mounted in the vehicle. The electric wires 12 included in the wire harness 10 are bundled while being branched in a form corresponding to a laying route in the vehicle.

As described above, the connector 14 is connected to the end of the electric wire 12. For example, the electric wire 12 is connected to the connector 14 via a terminal connected to the end thereof by crimping or welding.

The main body of the connector 14 is integrally formed of, for example, an insulating resin material. In the main body portion of the connector 14, a plurality of cavities capable of inserting and holding terminals at the end of the electric wire 12 are formed. When the terminals of the electric wires 12 are inserted and held in the cavities, the electric wires 12 are extended from the connectors 14. Hereinafter, the linear member including the electric wire 12 extending from the connector 14 is referred to as a wiring member 13.

<About wire harness assembly equipment>
The wire harness assembling apparatus 20 will be described. FIG. 2 is a schematic view showing the wire harness assembling apparatus 20. FIG. 3 is a schematic plan view showing the electric wire holding jig 30. FIG. 4 is a schematic rear view showing the electric wire holding jig 30. FIG. 5 is a cross-sectional view taken along line VV in FIG. FIG. 6 is an explanatory diagram showing a state in which the holding main body 33 is opened. FIG. 7 is an exploded perspective view showing the wire holding member 32 and the closing portion 46. FIG. 8 is a perspective view showing a modified example of the closing portion 46.

The wire harness assembling apparatus 20 is used to perform processing such as bundling on the wiring member 13 extending from the connector 14. The binding process is a process of binding the wiring member 13 extending from the connector 14 at a position away from the connector 14. The wire harness assembling apparatus 20 includes an electric wire holding jig 30 and a support member 50 that supports the electric wire holding jig 30. Here, the wire harness assembling apparatus 20 further includes a first robot 70 as a wire drawing mechanism, a second robot 80 as a bundling mechanism, an imaging unit 90 as a state information acquisition unit, and a processing control unit 100. Prepare.

The electric wire holding jig 30 includes a jig main body 31 in which a plurality of holding holes 35 are formed, and a closing portion 46 that closes a part of the plurality of holding holes 35.

The jig main body 31 includes a plurality (six here) of holding main bodies 33. Each holding main body 33 is formed with a holding hole 35 in which the wiring member 13 is disposed. By arranging the wiring member 13 in the holding hole 35, the holding main body 33 can hold the wiring member 13 without pinching it. The six holding main body portions 33 are arranged in a direction intersecting the axial direction of the holding hole 35 in which the wiring member 13 is disposed. Specifically, the holding main body portion 33 includes a receiving portion 34 and a guide portion 38.

The holding hole 35 in which the wiring member 13 can be disposed is formed in the receiving portion 34. The holding hole 35 is partially open in the circumferential direction. More specifically, the receiving portion 34 has a C-shaped portion 36 formed in a C-shape and an outer portion of the C-shaped portion 36 while approaching each other from both end edges along the circumferential direction of the C-shaped portion 36. And an extending piece 37 extending in the direction. The ends of the extension pieces 37 are not connected to each other and form an opening of the holding hole 35. In addition, between the tips of the extended pieces 37, they are the closest portions of the extended pieces 37. It is preferable that the space | interval of the front-end | tips of the extension piece 37 is smaller than the diameter of the electric wire 12 arrange | positioned. In addition, the opening in this specification points out the part discontinuous and discontinuous in the circumferential direction of the holding hole 35, and the space | interval does not necessarily need to be open. Therefore, the tips of the extension pieces 37 may be in contact with each other.

The guide portion 38 extends from both edge portions of the opening in the receiving portion 34. The guide portion 38 is inclined outward as it is away from the opening. Here, the guide portion 38 extends from the tip of the extending piece 37. The distance between the two guide portions 38 extending from the two extended pieces 37 increases as the distance from the two extended pieces 37 increases. Hereinafter, the surfaces of the two guide portions 38 facing each other are referred to as guide surfaces 39.

The holding body 33 is elastically deformable so as to widen the opening by pressing the wiring member 13 against the guide surface 39 toward the holding hole 35. Thereby, the wiring member 13 pressed against the guide surface 39 can be inserted into the holding hole 35 as it is. Further, in the state in which the wiring member 13 is disposed in the holding hole 35, the holding main body portion 33 is arranged on the inner peripheral surface of the extending piece 37 or in the vicinity thereof on the inner peripheral surface of the receiving portion 34 toward the outside. When the wiring member 13 is pressed, it can be elastically deformed to widen the opening. Thereby, the wiring member 13 pressed against the inner peripheral surface of the extending piece 37 or the vicinity thereof among the inner peripheral surface of the receiving portion 34 can be discharged to the outside of the holding hole 35 as it is. The force required for elastic deformation varies depending on the shape of the holding body 33 and the material constituting the holding body 33 such as resin or metal.

Here, the plurality of holding main body portions 33 include those having different holding hole 35 shapes. More specifically, the holding holes 35A and 35B of the four holding main body portions 33A and 33B out of the six holding main body portions 33 are circular, and the holding holes 35C of the two holding main body portions 33C are elliptical. . Of the four holding body portions 33A and 33B having the circular holding holes 35A and 35B, the holding holes 35A of the two holding body portions 33A are formed larger than the holding holes 35B of the remaining two holding body portions 33B. ing. As described above, the holding holes 35A, 35B, and 35C of the plurality of holding main body portions 33A, 33B, and 33C include those having different shapes and sizes. Thereby, the wiring member 13 can be appropriately held according to the difference in the number of wires 12 included in the wiring member 13 due to the difference in the shape of the connector 14 or the like, or the difference in the set position of the wires 12 in the connector 14. . For example, when the aspect ratio of the connector 14 is relatively large, the holding main body portion 33C having the elliptical holding hole 35C is suitable for disposing the wiring member 13 extending from the connector 14. Further, when the aspect ratio of the connector 14 is relatively small and the size of the connector 14 is also relatively small, a small circular holding hole 35B is provided when the wiring member 13 extending from the connector 14 is disposed. The holding main body part 33B having is preferable. When the aspect ratio of the connector 14 is relatively small and the size of the connector 14 is relatively large, a large circular holding hole 35A is provided when the wiring member 13 extending from the connector 14 is disposed. A holding main body 33A having the above is suitable.

However, it is not essential that the plurality of holding main body portions 33 include different shapes of the holding holes 35, and the holding holes 35 of all the holding main body portions 33 may be formed in the same shape.

Here, the six holding main body portions 33 each constitute a part of the wire holding member 32 formed separately. Therefore, the jig body 31 includes six wire holding members 32. The six wire holding members 32 are arranged in a line, and the adjacent wire holding members 32 are united with each other.

Each wire holding member 32 includes the holding main body portion 33 and the combined portion 40. Here, the description will be made assuming that one holding body portion 33 is formed on one wire holding member 32, but a plurality of holding body portions 33 may be formed on one wire holding member 32. That is, the number of holding main body portions 33 included in the jig main body portion 31 and the number of wire rod holding members 32 may not match. For example, two holding body portions 33 may be provided on one wire holding member 32. In this case, the shape of the holding holes 35 of the two holding main body portions 33 included in one wire holding member 32 may be the same or different.

The united part 40 is formed continuously with the holding main body part 33. Here, the united portion 40 has a rectangular parallelepiped base 41 formed so as to protrude outward from the outer surface of the bottom of the C-shaped portion 36, and a plurality (two in this case) protruding from both side surfaces of the base 41. And a fixed piece 42. Here, the fixed piece 42 protrudes in a direction intersecting the axial direction of the holding hole 35 with respect to the base 41 and intersecting the opening direction of the holding hole 35. A plurality of wire holding members 32 are arranged in the protruding direction of the fixed piece 42.

The thickness dimension of the fixed piece 42 is set smaller than the thickness dimension of the base portion 41 (here, half). One of the two fixed pieces 42 extends from one side along the thickness direction of the base 41. The other of the two fixed pieces 42 extends from the other side along the thickness direction of the base 41. For this reason, when two wire rod holding members 32 are provided adjacent to each other, one fixed piece 42 of one wire rod holding member 32 and the other fixed piece 42 of the other wire rod holding member 32 can overlap. Has been. And the insertion hole 43 is formed in the position (here center position of the fixed piece 42) corresponding when it overlaps among the fixed pieces 42. As shown in FIG.

The insertion hole 43 is formed so that a rod-shaped fastener 44 can be inserted. Then, in a state where the fixing pieces 42 of the adjacent wire holding members 32 overlap with each other, the rod-like fasteners 44 are passed through the insertion holes 43 of the two fixing pieces 42 so that the adjacent wire holding members 32 are combined.

A plurality of fasteners 44 (here, five) are provided. Each fastener 44 is formed in a long bar shape and is inserted through five sets of insertion holes 43.

In the example shown in FIG. 4, a screw 44 a and a nut that fastens the tip of the screw 44 a as a fastener 44 that holds four sets of adjacent wire holding members 32 located outside of the five sets of adjacent wire holding members 32. 44c is provided. Also, a screw 44b is provided as a fastener 44 for holding a pair of adjacent wire holding members 32 located in the center among the five sets of adjacent wire holding members 32, and the tip of 44b is formed on a slider 56 described later. It is fastened to the screw hole.

However, the fastener 44 is not limited to the above. For example, the fastener 44 may be composed of a pin and a cap provided at the end of the pin.

As described above, as the holding body portion 33, there are three types of holding body portions 33A, 33B, and 33C having different shapes of the holding holes 35A, 35B, and 35C. Therefore, here, as the wire holding member 32, there are three types of wire holding members 32A, 32B, and 32C having different holding main body portions 33A, 33B, and 33C. Here, in the three types of wire rod holding members 32A, 32B, and 32C, all the united portions 40 have the same shape.

Here, as shown in FIG. 4, the united portion 40 is formed point-symmetrically when viewed from the direction in which the wiring member 13 is taken in and out of the holding hole 35. Further, the holding body 33 is also formed point-symmetrically when viewed from the same direction. Therefore, the wire rod holding member 32 exhibits the same shape even if it is rotated by 180 degrees around the axis along the direction in which the wiring member 13 is taken in and out of the holding hole 35. For this reason, when connecting the wire holding members 32, the effort which considers direction can be saved.

The closing part 46 closes a part of the plurality of holding holes 35 to make it difficult to dispose the wiring member 13. Here, the closing portion 46 closes two of the six holding holes 35. For example, the holding main body 33 that is not used for assembling the wire harness 10 in the jig main body 31 is closed by the closing portion 46. Thereby, it is suppressed that the wiring member 13 is erroneously held by the wire holding member 132 that is not used.

In the example shown in FIG. 3, an embedded member 47 is disposed in the holding hole 35 as the closing portion 46 to fill the holding hole 35. In the example shown in FIG. 3, the buried member 47 is sanded for easy reading. The same applies to the following FIGS. 6, 10 to 14, and 16.

Here, the embedded member 47 is formed in a cylindrical shape. The embedded member 47 is formed slightly larger than the holding hole 35 and is press-fitted into the holding hole 35. Thereby, the embedded member 47 is fastened in the holding hole 35. As such, the embedded member 47 press-fitted into the holding hole 35 may be formed of an elastic material such as sponge or rubber. For example, the embedded member 47 may be inserted and removed in the axial direction of the holding hole 35.

However, it is not essential that the embedded member 47 is press-fitted into the holding hole 35. For example, it is conceivable that the embedded member 47 is formed slightly smaller than the holding hole 35 and is fastened in the holding hole 35 with a double-sided adhesive tape or the like.

Even when the embedded member 47 is press-fitted into the holding hole 35, the shape of the embedded member 47 is not limited to the above. For example, it is conceivable that the embedded member 47 is formed in a prismatic shape. It is also conceivable that the embedded member 47 is formed in a cylindrical shape instead of a columnar shape.

Further, as the closing portion 46, as shown in FIG. 8, it is conceivable to employ an outer closing member 48 that is disposed outside the holding hole 35 and closes the opening of the holding hole 35. In the example shown in FIG. 8, as such an outer closing member 48, an adhesive tape is stuck around the holding main body portion 33. The adhesive tape blocks all three openings, that is, the openings on both sides along the axial direction of the holding hole 35 and the opening through which the wiring member 13 is taken in and out of the holding hole 35. At least one of them is blocked. Anything can be used.

However, the outer closing member 48 is not limited to the adhesive tape, and may be a plate material, for example. In the case of using a plate material, for example, a configuration in which the base end portion of the plate material is fastened to the united portion 40 by a double-sided adhesive tape or the like and the tip end portion extends from the base end portion toward the opening can be considered. It is also conceivable that the base end portion of the plate material is fastened to the united portion 40 using the fastener 44.

At this time, the closing portion 46 and the holding main body portion 33 may be formed in different colors. Thereby, it becomes easy to visually recognize the closing part 46, and it becomes easy to recognize the holding hole 35 which can arrange | position the wiring member 13, and the holding hole 35 which cannot be arrange | positioned.

Here, the wire holding jig 30 is supported by the support member 50. The support member 50 includes a vertical frame 52 and a horizontal frame 54. The vertical frame 52 is supported in a standing state on the floor. The horizontal frame 54 is supported in a horizontal posture at a position on the floor by the vertical frame 52. The electric wire holding jig 30 is supported in a horizontal posture at a position on the floor by the horizontal frame 54. At this time, the electric wire holding jig 30 is supported in a posture in which the axial center direction of the holding hole 35 is along the extending direction of the vertical frame 52.

The horizontal frame 54 is formed in a long bar shape. The electric wire holding jig 30 is supported by the horizontal frame 54 so as to be slidable in the longitudinal direction of the horizontal frame 54. More specifically, the horizontal frame 54 is formed with a concave groove 54h extending along the longitudinal direction thereof. A slider 56 that can slide along the concave groove 54h is disposed in the concave groove 54h. The electric wire holding jig 30 is attached to the slider 56. Here, the wire holding jig 30 is attached to the slider 56 by screwing the screw 44 b into a screw hole formed in the slider 56. In the example shown in FIG. 3, the concave groove 54h is formed to open upward in the vertical direction, but this is not essential. The concave groove 54h may be formed so as to open in the horizontal direction or may be formed so as to open downward in the vertical direction.

However, it is not essential that the wire holding jig 30 is supported by the horizontal frame 54 so as to be slidable in the longitudinal direction of the horizontal frame 54. The electric wire holding jig 30 may be fixed to the support member 50 so as not to move.

Hereinafter, the direction along the longitudinal direction of the horizontal frame 54 is referred to as an x-axis direction, and two directions orthogonal to the direction are referred to as a y-axis direction and a z-axis direction. Therefore, as shown in FIG. 3, the holding holes 35 are arranged along the x-axis direction. Further, the opening of the holding hole 35 faces the y-axis direction. For this reason, the wiring member 13 is taken in and out along the y-axis direction with respect to the holding hole 35 (see FIGS. 6 and 9). Further, the extending direction of the vertical frame 52 is a direction along the z-axis direction, and here is a direction along the vertical direction.

The wiring member 13 extending from each connector 14 is held by the holding main body 33 in a state where the terminals at each end of the plurality of electric wires 12 are inserted and held in the corresponding connectors 14. Here, the wiring member 13 extending from the connector 14 is inserted through the holding hole 35 of the holding main body 33 so that the connector 14 is positioned above the holding main body 33 and extends in the vertical direction. Here, description will be made assuming that the wiring member 13 extending from one connector 14 is inserted into one holding hole 35. However, a plurality of wiring members 13 respectively extending from the plurality of connectors 14 may be inserted into one holding hole 35. In addition, in the state shown in FIG. 2, each wiring member 13 is not bundled. Therefore, each wiring member 13 extending from each connector 14 hangs down from each connector 14, and is curved toward the other connector 14 at a lower position between the connectors 14. Here, each wiring member 13 extending from each connector 14 hangs down from each holding main body 33 and is curved toward the other holding main body 33 at a position below each holding main body 33.

The wire drawing mechanism pulls out the plurality of wiring members 13 held without being held by the wire holding jig 30. The wire drawing mechanism includes a holding unit and a moving mechanism. The holding portion holds a portion of the wiring member 13 between the connector 14 and the wire holding jig 30 or the connector 14 in a state where the wiring member 13 is held by the wire holding jig 30. The moving mechanism moves the holding unit away from the electric wire holding jig 30. As described above, here, the first robot 70 is employed as the wire drawing mechanism.

The first robot 70 includes a robot arm 72 as the moving mechanism and a robot hand 74 as the holding unit provided at the tip of the robot arm 72. The robot hand 74 can be moved to each work position by driving the robot arm 72. The posture of the robot hand 74 can be changed by driving the robot arm 72. The robot hand 74 includes a plurality of fingers, and the connector 14 or the wiring member 13 extending from the connector 14 can be held by the plurality of fingers. In particular, the robot hand 74 holds the wiring member 13 extending from the connector 14 or the connector 14 in a state where the robot hand 74 is moved to the position of the connector 14 or a position below the connector 14 by driving the robot arm 72. In this state, the wiring member 13 can be pulled out from the wire holding jig 30 by moving the robot hand 74 upward by driving the robot arm 72 (see FIGS. 12 and 13). Hereinafter, the robot hand 74 will be described as gripping the connector 14.

At this time, the wiring member 13 is pulled out without being slid so as to abut both sides of the electric wire holding jig 30. For this reason, the portion between the connector 14 and the wire holding jig 30 in the drawn wiring member 13 may include a bent portion. In this case, it is preferable that the portion of the wiring member 13 between the connector 14 and the wire holding jig 30 is corrected to be as straight as possible by an operator or a wire correction mechanism before being bound later. For example, with the connector 14 positioned, the wiring member 13 is held as straight as possible by gripping the connector 14 side portion of the wiring member 13 and sliding the gripping portion toward the wire holding jig 30 side. Can be corrected. Such a correction operation of the electric wire 12 is also referred to as an ironing operation.

The bundling mechanism binds the plurality of wiring members 13 drawn by the wire drawing mechanism. As described above, here, the second robot 80 is employed as the bundling mechanism.

The second robot 80 includes a robot arm 82 and a bundling device 84 provided at the tip of the robot arm 82. The bundling device 84 can be moved to each work position by driving the robot arm 82. The binding device 84 is a device that binds the wiring member 13 with a binding member such as an adhesive tape or a binding band. As the binding device 84, for example, a known tape winding device that winds the adhesive tape around the wiring member 13 by rotating a tape winding body around which the adhesive tape is wound around the wiring member 13. Can be used. In particular, in a state where the wiring member 13 is held by the electric wire holding jig 30 at a lower position away from the connector 14, the bundling device 84 is moved above or below the electric wire holding jig 30 by driving the robot arm 82. The adhesive tape T is wound around the wiring member 13 by the bundling device 84 in a state where the wiring member 13 is moved to the next position, so that the wiring member 13 can be bound (see FIG. 14). Below, it demonstrates as what binds the wiring member 13 in the upper position (henceforth a planned binding location) of the electric wire holding jig 30 with the binding apparatus 84. FIG.

Further, some or all of the functions performed by the machining control unit 100 may be realized by hardware using a dedicated logic circuit or the like.

<Manufacturing method>
Based on the wire harness assembling apparatus 20, a method for manufacturing the wire harness 10 will be described.

First, as shown in FIG. 3, a part of the holding holes 35 among the plurality of holding holes 35 provided in the jig main body 31 is closed by a closing part 46 (step (a)). Here, although it demonstrates as what uses the burying member 47 as the closing part 46, this is not essential. As the closing part 46, as described above, the outer closing member 48 may be used. Further, both the embedded member 47 and the outer closing member 48 may be used.

More specifically, here, a columnar embedded member 47 is press-fitted into the holding hole 35A1 and the holding hole 35B1. In determining the holding hole 35 in which the closing portion 46 is provided, for example, the following policy may be considered.

That is, the first is to prevent interference between the connectors 14. More specifically, when at least one of the adjacent connectors 14 is large, when the wiring members 13 respectively extending from the adjacent connectors 14 are held in the adjacent holding holes 35, the adjacent connectors 14 are There is a risk of interference. In order to prevent this, it is conceivable to arrange the wiring member 13 with at least one holding hole 35. At this time, it is conceivable to provide a closing portion 46 in the vacant holding hole 35. In the example shown in FIG. 3, a closing portion 46 is provided in the holding hole 35A1 based on the policy.

Second, the wiring member 13 that forms a branch at a position close to the connector 14 is held in a nearby holding hole 35, and another wiring member 13 is disposed far away. In the example shown in FIG. 3, a closing portion 46 is provided in the holding hole 35 </ b> B <b> 1 based on the policy.

Next, a plurality of connectors 14 each having an end of a plurality of wires 12 connected thereto is prepared. And the wiring member 13 is arrange | positioned in the holding hole 35 in which the closing part 46 is not provided (process (b)). At this time, the wiring member 13 extending from the connector 14 is held without being held by the electric wire holding jig 30 in such a manner that the wiring member 13 can be pulled out. Here, as shown in FIG. 9, a portion of the wiring member 13 extending from the connector 14 and in the vicinity of the connector 14 is held by the holding body 33.

Specifically, here, the wiring member 13 extending from the connector 14 is pressed against the guide portion 38 of the wire holding member 32 to widen the opening. Then, the pressed wiring member 13 is disposed in the holding hole 35 through the opened opening. At this time, the wiring member 13 has a cross-sectional area smaller than the cross-sectional area of the holding hole 35 provided. As a result, the wiring member 13 is held without being held between the holding main body portion 33. In this state, the connector 14 can rotate around the axis along the axial direction of the holding hole 35. Further, in this state, the plurality of electric wires 12 hang down from the holding main body portion 33. Here, the wiring members 13 extending from the plurality of connectors 14 are respectively held by separate holding main body portions 33. The wiring member 13 may be disposed in the holding hole 35 by an operator or a robot. When the robot performs, the first robot 70 may perform it.

When the wiring members 13 extending from the four connectors 14 are held by the separate holding main body portions 33, they are as shown in FIG. Here, six holding main body portions 33 are provided, and the wiring members 13 are respectively disposed on the four holding main body portions 33. At this time, since the two holding holes 35A1 and 35B1 are closed by the closing portion 46, the wiring member 13 is prevented from being erroneously disposed in the holding holes 35A1 and 35B1.

Here, six wire rod holding members 32 are attached to one slider 56 as one set, but a plurality of wiring members 13 are divided into a plurality of wire rod holding members 32 attached to different sliders 56 from each other. May be arranged. In the example shown in FIG. 11, two wire holding member 32 groups each including three wire holding members 32 are attached to different sliders 56. The two wiring members 13 are held by the two wire holding member 32 groups, respectively. The wiring member 13 that forms a branch at a position close to the connector 14 may be held by the same wire holding member 32 group. Here, the wiring member 13 extending from the connectors 14a and 14b is held by one wire rod holding member 32 group, and the wiring member 13 extending from the connectors 14c and 14d is held by the other wire rod holding member 32 group. ing. Accordingly, the branch forming operation is facilitated by sliding the group of wire holding members 32 along the horizontal frame 54 and changing the interval between the two groups of wire holding members 32.

Next, in a state where the wiring member 13 is disposed in the holding hole 35, the wiring member 13 is pulled out in the axial direction of the holding hole 35 (step (c)). Specifically, as shown in FIG. 12, the portion of the connector 14 or the wiring member 13 between the connector 14 and the wire holding jig 30 (here, the connector 14) is moved by the robot hand 74 of the first robot 70. The robot hand 74 is lifted in this state. As a result, the portion of the wiring member 13 that is held by the holding main body 33 and the portion that is positioned below the ascending portion rise, and are sequentially pulled out to the connector 14 side from the wire holding jig 30 while passing through the holding main body 33. It is. When the two wiring members 13 constituting the branch are pulled out, they are as shown in FIG. The drawn wiring member 13 is maintained in this state. For example, the connector 14 may be held by the connector holding jig 110 provided at the end of the movement of the connector 14, or the robot hand 74 continues to hold the connector 14 at the position of the movement of the connector 14. There may be.

Here, when the connector 14 or the wiring member 13 is held by the robot hand 74, a holding error may occur if the position and posture of the connector 14 are not constant. Further, the connector 14 or the wiring member 13 may be held from an undesired direction and the connector 14 or the wiring member 13 may be damaged. In particular, here, since the connector 14 can rotate around the axis of the holding hole 35, the position and posture of the connector 14b may not be constant. In order to hold the connector 14 or the wiring member 13 more reliably by the robot hand 74 even when the position and posture of the connector 14 are unstable in this way, here, the wiring member extending from the connector 14 and the connector 14 is used. 13 state information is acquired.

That is, the imaging unit 90 images an area including the terminal of the wiring member 13. For example, a region including the connector 14 to be held and a member that is likely to be an interference when the connector 14 is held by the robot hand 74 around the connector 14 is imaged. Then, the processing control unit 100 acquires the holding position and the like of the robot hand 74 based on the state information of the connector 14 and the wiring member 13 in the captured image captured by the imaging unit 90. For example, the processing control unit 100 performs pattern recognition on the connector 14 by comparing it with the shape of the connector 14 input in advance in the captured image, and determines the position and orientation of the connector 14. Then, based on the determined position and orientation of the connector 14, an approach path in which the robot hand 74 does not interfere with other connectors 14, the wiring members 13, etc., and a suitable position and orientation of the robot hand 74 with respect to the connector 14 to be held, etc. get. Further, when the robot hand 74 holds the wiring member 13, it is conceivable to extract the image of the wiring member 13 by removing the background from the captured image and acquire the holding position of the robot hand 74. The background may be acquired in advance from a captured image captured without the wiring member 13. Based on the holding position and the like acquired in this way, the machining control unit 100 controls the operation of the robot hand 74. It is preferable that the acquisition of the imaging and the holding position is performed every time before the connector 14 or the wiring member 13 is held.

Next, the drawn wiring member 13 is processed. Here, although it demonstrates as what binds to the drawn-out wiring member 13, processing other than binding processing, such as attachment processing of an exterior member, may be performed. Further, here, as the bundling process, the wiring members 13 extending from the plurality of connectors 14 are collectively bundled to form a branch, but the wiring members 13 extending from one connector 14 are bound. It may be a thing.

More specifically, by pulling out the wiring members 13 extending from the two connectors 14a and 14b respectively set to the two holding main body portions 33 by a predetermined distance, as shown in FIG. The planned binding location is moved to the vicinity of the electric wire holding jig 30 (here, the position adjacent to the upper side of the electric wire holding jig 30).

In this state, the bundling device 84 is moved to the planned bundling position, and the wiring member 13 extending from the connector 14 is bundled. Here, the wiring members 13 extending from the two connectors 14a and 14b are bundled together by the adhesive tape T. As a result, the bound portion forms a branching portion.

Thereafter, when the bundling device 84 is retracted, as shown in FIG. 14, two wiring members 13 extending from the two connectors 14 are bundled at the planned bundling location.

The wire harness 10 in which the wiring members 13 extending from each connector 14 are bundled is manufactured by performing the above bundling process on each of the plurality of connectors 14 or on the branch points.

According to the electric wire holding jig 30 configured as described above and the wire harness assembling apparatus 20 including the electric wire holding jig 30, since the holding holes 35 </ b> A <b> 1 and 35 </ b> B <b> 1 that are not used are closed by the closing portion 46, the wiring member extending from the connector 14. When the 13 is selectively set in the holding hole 35, it is possible to suppress the occurrence of a setting error. For this reason, when assembling the wire harnesses 10 having different numbers of connectors 14 using the same assembling apparatus, it is possible to suppress misplacement of the connectors 14.

Further, when the embedded member 47 that is accommodated in the holding hole 35 is provided as the closing portion 46, the holding hole 35 can be reliably closed by the closing portion 46.

Further, when the outer closing member 48 positioned outside the holding hole 35 is provided as the closing portion 46, the closing portion 46 can be easily provided.

Further, when the closing portion 46 and the holding main body portion 33 are formed in different colors, the closing portion 46 is easily visible.

Moreover, since the electric wire holding jig 30 is supported by the supporting member 50 so as to be slidable in the longitudinal direction of the supporting member 50, a branch is formed in the wire harness 10 by sliding the electric wire holding jig 30. Branch formation work becomes easy.

{Modification}
In the embodiment, the closing portion 46 is formed so as not to hold the one electric wire 12, but the closing portion 46 may be formed with a slit 47 s capable of inserting and holding the one electric wire 12. The width dimension of the slit 47s is set to be smaller than the width dimension of the electric wire 12, and the electric wire 12 is preferably sandwiched between both side edges of the slit 47s.

In the example shown in FIG. 15, slits 47 s are formed in the embedded member 47. The slit 47s is formed so as to reach the outer edge of the circle from the inside of the circle. The embedded member 47 is inserted and held in the holding hole 35 so that the opening of the slit 47 s is in the same direction as the opening of the holding hole 35. Thereby, the one electric wire 12 can be inserted into the slit 47s through the opening of the holding hole 35 and the opening of the slit 47s. When the one electric wire 12 is inserted and held in the slit 47s, it becomes as shown in FIG.

By providing the slit 47 s in the closing portion 46 in this way, the closing portion 46 can be used as an end holding portion that holds the end of the electric wire 12 before being inserted into the connector 14. No need to prepare. Note that the end portion of the electric wire 12 inserted and held in the slit 47s is inserted into the connector 14 after the wiring member 13 is pulled out, for example. When the object to be manufactured is a sub-harness obtained by dividing a wire harness (also referred to as a sub-assembly), the end of the electric wire 12 inserted and held in the slit 47s later combines the sub-harnesses to form a wire harness. Inserted into the connector.

Here, in the example shown in FIG. 17, when the embedded member 47 provided with the slit 47 s is disposed in the holding hole 35, the opening of the slit 47 s is arranged so as to face the position where the inner peripheral surface of the holding hole 35 is located. Has been established. This makes it difficult to insert and hold the one electric wire 12 in the slit 47s.

Thus, by disposing the opening of the slit 47s so as to face the position where the inner peripheral surface of the holding hole 35 is located, when the closing portion 46 provided with the slit 47s is not used as an end holding portion, It can suppress that the set mistake of the electric wire 12 arises. Moreover, it is not necessary to prepare both the closing part 46 provided with the slit 47s and the closing part 46 provided with no slit 47s, leading to a reduction in the number of parts.

In the example shown in FIG. 15, the embedded member 47 is provided with the slit 47s, but the outer closing member 48 may be provided with the slit 47s. In the example shown in FIG. 15, the slit 47s is provided so as to be inserted and held using the opening of the holding hole 35 when the one electric wire 12 is inserted and held in the slit 47s, but this is not essential. . For example, in the columnar embedded member 47, an end portion along the central axis direction may protrude from the holding hole 35, and a slit along a plane intersecting the central axis direction may be provided at the protruding portion.

Further, in the embodiment, the jig main body 31 has been described as being formed into a shape in which the holding hole 35 is opened and the electric wire 12 can be inserted by pressing the electric wire 12 against the opening periphery of the holding hole 35. This is not essential. The jig body part may have a holding hole that is opened and closed by the opening and closing part. FIG. 18 shows an example of such a jig body 131.

The jig main body 131 shown in FIG. 18 includes three wire holding members 132 and an opening / closing member 140.

The wire holding member 132 includes two claw members 134 that are connected around the shaft portion 135 so as to be openable and closable, and a biasing member 138 that biases the two claw members 134 in the closing direction. The wire holding member 132 will be described as being formed in a so-called laundry scissors shape.

Each of the two claw members 134 has a shaft portion 135, a divided holding main body portion 136, and an opening / closing portion 137. The two claw members 134 are formed in the same shape and are connected to each other in opposite directions.

The shaft portion 135 is a portion that serves as a rotation fulcrum for the two claw members 134. Here, the two claw members 134 are rotatably connected around the shaft portion 135.

The split holding main body 136 extends from the shaft 135 to one side. The divided holding main body 136 is formed with a divided holding hole 136a obtained by dividing the holding hole 133a. The two divided holding holes 136a formed by combining the two claw members 134 form a holding hole 133a through which the wiring member 13 can be inserted, and the two divided holding main body parts 136 form a holding main body part 133.

The opening / closing part 137 extends from the shaft part 135 to the other side. Each opening / closing part 137 of the two claw members 134 is formed so as to be located at a position away from each other with the holding hole 133a closed. Then, by bringing the open / close portions 137 of the two claw members 134 closer to each other, the two claw members 134 rotate around the shaft portion 135 and the holding hole 133a is opened.

Here, the biasing member 138 is formed in a ring spring shape in which a part in the circumferential direction is interrupted. One end portion of the urging member 138 in the circumferential direction is connected to the outer surface side of the divided holding main body portion 136 of the one claw member 134. Further, the other end in the circumferential direction of the biasing member 138 is connected to the outer surface side of the divided holding main body 136 of the other claw member 134. Each claw member 134 is formed with a through hole 137h through which an intermediate portion of the biasing member 138 passes (see FIG. 20). A central portion between the two through holes 137 h in the urging member 138 is disposed on the opposite side of the shaft portion 135 from the holding hole 133 a with a space from the shaft portion 135.

The opening / closing member 140 includes two combined members 141. Each uniting member 141 includes a flat plate portion 142 and three pressing pieces 143 protruding from the flat plate portion 142. Here, the flat plate portion 142 is formed in a rectangular flat plate shape. The three pressing pieces 143 are formed in a manner extending along the short direction toward the end in the short direction of the flat plate portion 142. Further, the three pressing pieces 143 are formed at regular intervals (here, at equal intervals) from the one end side in the longitudinal direction of the flat plate portion 142. The two united members 141 are formed in the same shape. The two united members 141a and 141b are arranged so that the flat plate portion 142 faces each other and so that the pressing piece 143 of the unit butts against the flat plate portion 142 on the other side (see FIG. 20). That is, the united member 141b takes a posture in which the united member 141a is rotated 180 degrees around the axis along the short direction of the flat plate part 142a. Three wire rod holding members 132 are arranged in parallel in the longitudinal direction of the flat plate portion 142 between the flat plate portion 142a of the combined member 141a and the flat plate portion 142b of the combined member 141b. Further, the three wire holding members 132 are arranged in such a manner that the two opening / closing portions 137 of the wire holding members 132 are positioned between the pressing piece 143a of the uniting member 141a and the pressing piece 143b of the uniting member 141b. .

Here, when the two united members 141 slide, the three wire holding members 132 are collectively opened and closed. More specifically, from the state in which the flat plate portions 142a and 142b overlap in a plan view (the state shown in FIG. 18), the two united members 141 are mutually aligned along the direction in which the pressing pieces 143 are arranged as shown in FIGS. When the relative movement is performed in the opposite direction, the intervals between the three sets of pressing pieces 143a and 143b located on opposite sides of the opening / closing portion 137 are changed. In other words, the three sets of pressing pieces 143a and 143b move so as to approach together, and the opening / closing portions 137a and 137b of the three wire holding members 132 are simultaneously pressed by the corresponding sets of pressing pieces 143a and 143b. As a result, the two claw members 134 in each wire holding member 132 rotate around the shaft portion 135 so that the two opening / closing portions 137a and 137b come close to each other, and the holding holes 133a in each wire holding member 132 are simultaneously opened. It becomes.

Further, here, the opening / closing member 140 further includes a fastener 144. The wire holding member 132 is held by the fastener 144 and the two combined members 141. More specifically, each flat plate portion 142 is formed with three insertion holes 142h into which the rod-like fasteners 144 can be inserted. Each insertion hole 142h is formed in a long hole shape. The longitudinal direction of the insertion hole 142h is a direction in which the plurality of pressing pieces 143 are arranged, that is, a direction in which the two combined members 141 are relatively moved. Accordingly, the two flat plate portions 142 can be relatively moved in the direction in which the pressing pieces 143 are arranged in a state in which the fastener 44 is inserted into the insertion hole 142h.

Three fasteners 144 are provided. Each fastener 144 is formed in a long bar shape and is inserted through three sets of insertion holes 142h. Each fastener 144 is inserted into a portion between the urging member 138 and the shaft portion 135 with respect to each wire holding member 132.

When the fastener 144 is inserted into the insertion hole 142h of the flat plate portion 142 and partially penetrates the wire rod holding member 132, the wire rod holding member 132 moves in the direction along the plane of the flat plate portion 142. Is regulated. Further, the movement of the wire holding member 132 in the direction orthogonal to the plane of the flat plate portion 142 is restricted by the flat plate portion 142. Further, the rotation of the wire holding member 132 around the fastener 144 is restricted by the pressing piece 143 around the fastener 144. As described above, the wire holding member 132 is held by the two united members 141 and the fasteners 144.

In the example shown in FIG. 18, a screw 144 a and a nut 144 c that fastens the tip of the screw 144 a are provided as a fastener 144 that holds the two wire holding members 132 positioned outside of the three wire holding members 132. . A screw 144 b is provided as a fastener 144 that holds the wire holding member 132 located at the center of the three wire holding members 132, and the tip of the screw 144 b is fastened to a screw hole formed in the slider 56. .

In this way, when the plurality of holding holes 133a are collectively opened and closed, the closing portion 146 is preferably formed so as not to hinder the opening and closing operation of the holding holes 133a. In the example shown in FIG. 18, an outer closing member 148 is provided as such a closing portion 146. The outer closing member 148 is formed in a rectangular plate shape, and a base end portion is disposed between the head of the screw 44a and the flat plate portion 142a. Moreover, the front-end | tip part has block | closed the opening along the axial center direction of the holding hole 133a.

{Other variations}
In the embodiment, the electric wire holding jig 30 has been described as a combination of a plurality of wire holding members 32, but this is not essential. For example, the electric wire holding jig may be formed such that a plurality of holding main body portions 33 protrude from the long base portion 41.

In the embodiment, the wire harness assembling apparatus 20 has been described as being used so that the z-axis direction is in the direction along the vertical direction, but this is not essential. For example, the wire harness assembling apparatus 20 may be used such that the y-axis direction is a direction along the vertical direction.

In the embodiment, the adjacent wire holding members 32 have been described as being united by the fixing piece 42 and the fastener 44, but this is not essential. For example, the wire holding member may be united by another united structure such as a magnet or a locking structure.

In addition, each structure demonstrated in the said embodiment and each modification can be suitably combined unless it mutually contradicts.
