Description

The present invention relates to a technique for assembling a wire harness to a vehicle.

The wire harness that electrically connects the electrical components on the vehicle has a shape in which a narrow gap in the vehicle is stretched. Therefore, when the wire harness WH is deployed, it is in a state of expanding to a large area as a whole.

If such a wire harness is transported in a deployed form, the transportation efficiency will deteriorate. Therefore, in order to improve the transportation efficiency, after manufacturing the wire harness, the wire bundle is folded and bound with a temporary fixing tape that can be easily cut by hand to form a package.

Therefore, as the work of attaching the wire harness to the vehicle, the wire harness in the shape of a package is expanded and crawls on the vehicle, the protrusion of the locking part is inserted into the hole on the vehicle side and fixed, and the connector of the wire harness terminal is fixed. Is fitted with the electrical components on the vehicle side and electrically connected. In this case, the locking component and the connector among the components of the wire harness are handled.

Here, Patent Document 1 discloses a technique of providing an information holding portion for holding information on a mounting position for each connector and a mounting position for each fixed component on a wire harness molded into a package shape. Examples of the mounting position information for each connector include cases where the identification information is unique to each wire harness manufactured and cases where the information is managed by the model number of the wire harness.

Assuming that such a wire harness is attached to a vehicle by a robot, it is conceivable that the robot grabs a connector whose location is specified and connects it to a connector on the other side in the vehicle.

However, depending on the form of the wire harness, another component such as another connector may be connected to the connector to be handled by the robot. In such a case, it is difficult for the robot to handle a plurality of parts at the same time. Therefore, when the robot grabs one connector and moves it toward the other connector, another component also moves with the movement of the one connector.

Then, when one connector is grabbed and moved toward the other connector, other parts may interfere with other parts of the vehicle. In particular, in a vehicle, various parts are densely packed, and the wire harness mounting work is often performed in a very narrow environment, so that other parts of the wire harness interfere with other parts of the vehicle. It is difficult to avoid that.

Therefore, it is an object of the present invention to enable the wire harness to be assembled to the vehicle while suppressing the vehicle assembly parts of the wire harness from interfering with the vehicle parts.

Hereinafter, the wire harness information management system according to the embodiment will be described. FIG. 1 is a schematic overall view showing a wire harness information management system, FIG. 2 is a schematic view showing a wire harness module 10 in a package form, and FIG. 3 is a schematic view showing a wire harness module 10 in a deployed form. ..

The wire harness information management system includes a wire harness module 10 including a wire harness WH, and a storage unit 52 as an information storage unit.

The wire harness module 10 includes a wire harness WH and a tag 12.

The wire harness WH includes a wire harness main body 14 and a plurality of vehicle assembly parts 16 and 18 provided on the wire harness main body 14. The wire harness WH is formed in a package shape.

The wire harness main body 14 is configured by binding a plurality of electric wires 13 according to the assembly form in the vehicle. Here, a plurality of electric wires 13 are bundled while appropriately branching according to the wiring path of the vehicle. Bundling is performed by a binding member such as an adhesive tape or a binding band. In addition, an exterior member such as a corrugated tube or a protector may be attached to the wire harness main body 14. In each figure, one wire is shown regardless of whether the number of electric wires 13 is one or a plurality.

The vehicle assembly parts 16 and 18 are parts provided on the wire harness main body 14 and assembled to the vehicle. Here, the vehicle assembly parts 16 and 18 include the connector 16 and the vehicle fixing parts 18. Hereinafter, the vehicle assembly parts 16 and 18 may be distinguished and described as the connector 16 and the vehicle fixing parts 18.

The connector 16 is attached to the end of the wire harness main body 14 and is connected to the mating connector. The mating side connector is a connector for various electric parts mounted on a vehicle. By inserting and connecting the connector 16 to the mating connector, the connector 16 is assembled to the vehicle. As a result, the end portion of the wire harness main body 14 is supported at a predetermined position of the vehicle.

As the vehicle fixing component 18, a clamp component with a band, a clamp component with a sleeve, or the like is assumed. The clamp component with a band is fixed to the wire harness main body 14 by winding the band portion around the wire harness main body 14. The clamp component with sleeves is fixed to the wire harness main body 14 by winding and fixing the sleeve portion to the wire harness main body 14 with an adhesive tape or the like. The vehicle fixing component 18 is fixed to the vehicle by inserting and fixing the vehicle fixing component 18 into the fixing hole formed in the vehicle body. By fixing the vehicle fixing component 18 to a predetermined position of the vehicle in this way, the intermediate portion in the extending direction of the wire harness main body 14 and the like are supported at a predetermined position along the predetermined wiring path.

An identification code is assigned to the wire harness WH. This identification code is recorded on the tag 12. The identification code may be a number unique to the manufactured wire harness WH, or may be a number for each lot of the manufactured wire harness WH. Here, it is assumed that the identification code is an identification code unique to each wire harness WH. The identification code may be recorded on the tag 12 in an electromagnetically or optically readable format. For example, a graphic symbol such as a barcode may be optically readable printed on the tag 12. The tag 12 may be provided with a magnetic stripe that can be read magnetically. The tag 12 may include a wireless tag device that wirelessly transmits a stored identification code by an electromagnetic field or a radio wave. The tag 12 may be printed with human-readable characters or numbers.

A part of the tag 12 is attached to the wire harness WH by being wound around the wire harness WH, or attached to the wire harness WH via a linear body such as a wire.

The wire harness WH is manufactured by spreading a plurality of electric wires on a wire harness assembly drawing plate and binding them at appropriate points. The manufactured wire harness WH has, for example, a form in which at least one (here, four) branch line portions WHb are branched from the trunk line portion WHa (see FIG. 3). The manufactured wire harness WH is deployed on an inspection drawing board, and an inspection such as a continuity inspection is performed on the wire harness WH on the inspection drawing board. After the inspection, the wire harness WH is removed from the inspection drawing plate and formed into a package shape.

When forming the packing form, the main wire portion WHa of the wire harness WH is folded into a U shape, or the branch wire portion WHb is folded into the main wire portion WHa to make the wire harness WH compact and outward. The form has few protruding parts (see the arrow in FIG. 3). In this state, the folded trunk line portion WHa and the branch line portion WHb are kept in a bundled form by the binding member 11 for forming a package (see FIG. 2). As the bundling member 11 for forming a package, for example, an adhesive tape having a cut can be used. By forming the wire harness WH in the form of a package in this way, the transportation efficiency of the wire harness WH can be improved.

The tag 12 is attached to the wire harness WH at any timing of manufacturing and inspecting the wire harness WH, forming it into a package shape, or thereafter.

The storage unit 52 is a storage unit 52 of the management server 50. The storage unit 52 stores the position information 53 regarding at least one of the plurality of vehicle assembly parts 16 and 18 in the package form of the wire harness WH, and the shape information 54 of the wire harness WH in the released state of the package. is doing. Here, the storage unit 52 stores the position information 53 and the shape information 54 in association with the identification information.

That is, the management server 50 is composed of a computer including a processor and a storage unit 52. The management server 50 may be configured by a single computer or may be configured by a plurality of computers.

The storage unit 52 stores the position information 53 and the shape information 54 in association with the identification information.

The identification information is the identification information assigned to the wire harness WH and recorded on the tag 12.

The position information 53 is information indicating the positions of the connector 16 and the vehicle fixing component 18 in the package form. The position information 53 is, for example, the position coordinates of the connector 16 and the vehicle fixing component 18 in the three-dimensional coordinate system. The position information 53 is provided as position information when the robot that assembles the wire harness WH to the vehicle grips the connector 16 and the vehicle fixing component 18. The position information 53 may be generated by an operator or the like inputting the positions of the connector 16 and the vehicle fixing component 18 in the wire harness WH having an ideal packaging form. In this case, as will be described later, when the robot grips the connector 16 and the vehicle fixing component 18, the region where the connector 16 and the vehicle fixing component 18 are expected to exist is imaged, and the connector 16 and the vehicle are based on the imaged data. Object recognition of the fixed parts 18 may be performed to determine their more accurate positions.

In this case, even if the connectors 16A and 16B to be gripped and the vehicle fixing component 18 are hidden by a line bundle or the like, the positions can be specified, so that the gripping work thereof can be easily performed.

The position information 53 is generated by recognizing the objects of the connector 16 and the vehicle fixing component 18 from the two-dimensional data or the three-dimensional data obtained by imaging the wire harness WH in the package form with a two-dimensional camera or a stereo camera. You may.

As will be described later, when the robot grips one connector 16, another connector 16 close to the one may move according to the one connector 16. It is not necessary to specify the position of the other connector 16 in the package form. Therefore, the position information does not need to include all the position information of the connector 16 and the vehicle fixing component 18 in the package form.

The shape information 54 is the shape information of the wire harness WH in a state where the package is released. The robot that assembles the wire harness WH to the vehicle grasps one of the connector 16 and the vehicle fixing component 18 (for example, one connector 16) and directs the shape information toward the fixing destination (for example, the connection destination connector). When moving, it is provided as data for predicting the movement, position, etc. of the other connector 16, the vehicle fixing component 18, etc. that move with the movement of the one connector 16. The shape information is the position of the other connector 16, the vehicle fixing component 18, etc. after fixing one of the connector 16 and the vehicle fixing component 18 (for example, one connector 16) to the fixing destination (for example, the connection destination connector). It can also be used as data for predicting such factors.

Here, the shape information 54 includes design information 54a and unique information 54b.

The design information 54a is information on the design of the wire harness WH. For example, information such as from which position in the trunk line portion WHa the branch line portion WHb branches, the length of the branch line portion WHb, the distance from the branch portion to each connector 16, the distance between the connector 16 and the vehicle fixing component 18, and the like. Is.

The design information 54a is common information if the wire harness WH has the same product number.

The unique information 54b is the unique information of the actually manufactured wire harness WH, and even if the wire harness WH has the same part number, the unique information is different for each actually manufactured wire harness WH.

That is, since the wire harness WH is formed by binding a plurality of flexible electric wires with a flexible adhesive tape or the like, the extension direction of the branch line portion WHb, the bending of the trunk line portion WHa and the branch line portion WHb. Individual differences may occur in terms of direction.

For example, as shown in FIG. 4, even if the branch line portion WHb is designed to extend at a predetermined angle with respect to the trunk line portion WHa, there are subtle differences depending on the winding method of the adhesive tape and the like. Can occur. Therefore, the branch line portion WHb can extend at an angle larger or smaller than a predetermined angle with respect to the trunk line portion (see the branch line portion WHb indicated by the alternate long and short dash line).

Further, for example, as shown in FIG. 5, the trunk line portion WHa or the branch line portion WHb is slightly bent and habitual depending on how the adhesive tape is wound around a plurality of bundled electric wires or the habit of the electric wires. (Refer to the branch line portion WHb indicated by the two-dot chain line).

The unique information may be, for example, image pickup data of the wire harness WH. The imaging data may be two-dimensional data or three-dimensional data. By recognizing the shape of the trunk line portion WHa and the branch line portion WHb from the imaged data and following the path, the extension direction of the branch line portion WHb, the degree of bending of the trunk line portion WHa and the branch line portion WHb, etc. are recognized. be able to. The unique information may be the imaging data itself, or may be data indicating the extension direction and the degree of bending acquired from the imaging data.

The information peculiar to the wire harness WH is likely to appear remarkably in the form in which the wire harness WH is not formed in the package form, that is, in the unconstrained form. Therefore, the imaging data may be data captured after the wire harness WH is manufactured and before it is formed in the package. Specifically, one of the states after removing the manufactured wire harness WH from the wire harness assembly drawing board and before setting the wire harness WH on the inspection drawing board, or after removing the wire harness WH from the inspection drawing board. The image data may be an image of the wire harness WH in any state before the wire harness WH is formed in the package form. The image pickup data is transmitted from the image pickup apparatus to the management server 50 together with the identification code of the wire harness WH to be imaged, is associated with the identification code, and is stored in the storage unit 52.

However, the image pickup data may be an image of a wire harness in the form of a package.

The management server 50 is communicably connected to the terminal device 20 through the communication line 40.

The terminal device 20 is provided in a factory or the like where the wire harness WH is assembled to the vehicle. When the wire harness WH in the form of a package is brought into the factory, the identification code assigned to the tag 12 of the wire harness WH is input to the terminal device 20. The identification code may be input through a reader capable of reading the identification code of the tag 12, or may be input by an operator.

When the identification code is input to the terminal device 20, the identification code is transmitted to the management server 50. When the management server 50 receives the identification code, the management server 50 reads out the position information 53 and the shape information 54 corresponding to the identification code from the storage unit 52 and transmits them to the terminal device 20.

The terminal device 20 transmits the position information 53 and the shape information 54 to the vehicle mounting device 30 for assembling the wire harness WH to the vehicle. The vehicle mounting device includes a robot such as an articulated robot and a control device for controlling the robot, and controls the robot while referring to the position information 53 and the shape information 54, and the connector 16 of the wire harness WH and the connector 16 of the wire harness WH. The work of assembling the vehicle fixing parts 18 to the vehicle is carried out.

An example of assembly work using the position information 53 and the shape information 54 will be described.

As shown in FIG. 6, consider a case where two electric devices 62 and 64 are arranged on the back side of the reinforcement 60, and two connectors 16 are inserted and connected to the electric devices 62 and 64 from the front side thereof. Here, in order to distinguish between the two connectors 16, the connector 16B at the end of the trunk line portion WHa and the connector 16A at the end of the branch line portion WHb branching from the trunk line portion WHa are used. An L-shaped bracket 66 is arranged on the way of the connector 16A toward the electric device 62. It is assumed that the bracket 66 is located below and one side of the trunk line portion WHa connected to the connector 14A via the branch line portion WHb.

As described above, when the connectors 16A and 16B of the wire harness WH are inserted and connected to the electric devices 62 and 64, various parts of the vehicle may be present in the middle of the insertion and connection. In such a case, if the connectors 16A and 16B interfere with the bracket 66 and the like, the connectors 16A and 16B may be caught by the bracket 66 and the like, hindering smooth work and causing damage to the connectors 16A and 16B. Therefore, it is necessary to consider suppressing such interference.

For example, consider a case where an operator manually inserts and connects the connectors 16A and 16B to the electric devices 62 and 64 and fixes the vehicle fixing component 18 to the bracket 66. In this case, for example, with the connector 16B held in the left hand, the connector 16A is picked up by the fingertip of the left hand and inserted and connected to the electric device 62, then the right hand is turned from the right side of the bracket 66 and the connector is connected from the left hand to the right hand. The 16B is replaced and the connector 16B is inserted and connected to the electric device 64. After that, a procedure is assumed in which the vehicle fixing component 18 is held by the right hand and the vehicle fixing component 18 is fixed to the bracket 66 so that the harness extra length is appropriate.

Similarly, when working with a robot, it is assumed that the work is performed in the order of the insertion connection of the connector 16A, the insertion connection of the connector 16B, and the fixing of the vehicle fixing component 18. In this case, a dual-arm robot or the like equipped with a hand capable of gripping a plurality of parts may be able to realize the same work as a human.

However, it is difficult to realize a hand that simultaneously handles a plurality of connectors 16A and 16B, vehicle fixing parts 18 having a positional relationship away from them, and the like. In addition, since the harness assembly work tends to be concentrated on a part of a wide range, it is relatively difficult to plan the work suitable for an expensive dual-arm robot having a large work area. Therefore, it is preferable to assume that the work is performed by one articulated robot or the like that handles one part at a time.

In that case, as shown in FIG. 7, the connector 16A is removed by breaking the binding member 11 from the wire harness WH in a form that is partially or wholly maintained in the package shape, and then as shown in FIG. It is conceivable that the connector 16A is linearly moved toward the electric device 62 to perform the insertion connection work. However, in this case, the branch line portion WHb extending from the connector 16A is connected to the middle of the trunk line portion WHa and folded, and the connector 16B is attached to the end portion of the trunk line portion WHa on the distal end side. If the connector 16B moves linearly so as to be dragged along with the linear movement of the connector 16A, the connector 16B and the trunk line portion WHa connected to the connector 16B may interfere with the bracket 66 and the like.

Therefore, if the shape information 54 is given to the control device of the robot in advance, the movement and position of the connector 16B and the trunk line portion WHa connected to the connector 16B when the connector 16A is inserted and connected to the electric device 62 can be estimated. .. For example, the movement of the connector 16A is based on shape information such as the length of the branch line portion WHb extending from the connector 16A and the length of the portion of the trunk line portion WHa to which the branch line portion WHb is connected to the connector 16B. It is possible to predict how far the connector 16B and the trunk line portion WHa may be from the path. Based on this prediction, it is possible to create an operation route plan that suppresses interference between the connector 16B, the trunk line portion WHa, and vehicle parts.

For example, when it is predicted that the portion of the connector 16B and the trunk line portion WHa on the connector 16B side may exist within a distance range of x cm from the movement path of the connector 16A, the movement of the connector 16A is performed as shown in FIG. The movement path P may be set so that the path P passes a distance of x cm or more from the position of the bracket 66. At this time, the movement path P is set so as to pass a distance larger than x cm in consideration of the length of the portion of the trunk line portion WHa from the portion where the branch line portion WHb is connected to the connector 16B. You may.

It is assumed that the position information itself of the vehicle parts such as the bracket 66 is stored in the control device itself of the robot performing the assembling work.

As the shape information 54, the design information 54a can be used as described above.

Further, as described above, individual differences may occur in the shape of the wire harness WH made of a flexible material. Therefore, if the unique information 54b is included as the shape information, it is possible to execute the operation route plan according to the individual difference in the shape of the wire harness WH based on the unique information 54b. For example, if the branching direction of the branch line portion WHb from the trunk line portion WHa is close to the direction perpendicular to the trunk line portion WHa, the movement path of the connector 16A should be set to be farther away from the vehicle parts in order to suppress interference. Just do it. Further, if the branching direction of the branch line portion WHb from the trunk line portion WHa is tilted at a small angle with respect to the trunk line portion WHa, the movement path of the connector 16A is set to pass closer to the vehicle parts. May be good. Further, when the movement or position of the connector 16B or the like estimated from the branch direction interferes with the vehicle parts, the movement path P may be changed so as to avoid the interference. Further, the posture of the connector 16A held by the robot may be changed to change the movement and position of the connector 16B and the like.

The robot control device may set the movement path P based on the design information 54a and then correct the movement path P based on the unique information 54b, or may correct the movement path P based on the unique information 54b. It may be set, or in the latter case, the design information 54a may be omitted.

Similarly, when the trunk line portion WHa and the branch line portion WHb have a bent habit, the movement of the connector 16B and the trunk line portion WHa while the connector 16A is moving is predicted in consideration of the bent habit. Based on this prediction, an operation route plan that suppresses interference between the connector 16B, the branch line portion WHb, and the vehicle parts may be created.

Further, as shown in FIG. 10, after the connector 16A is connected to the electric device 62, the connector 16B may be located on the back side of the bracket 66 or the like, and is viewed from the object recognition camera on the robot side. It is assumed that the connector 16B will be difficult to recognize.

Even in such a case, since the position of the connector 16A connected to the electric device 62 is fixed, the robot control device of the connector 16B is based on the above-mentioned shape information with the position of the connector 16A as a reference. You can guess the position. Therefore, the robot control device moves the camera for object recognition on the robot side to a position where the predicted existing region of the connector 16B is to be imaged, thereby performing image pickup, thereby imaging the connector 16B and the position. Can be recognized.

In this case, the shape information 54 may be the design information 54a as described above. Further, when the shape information 54 includes the unique information 54b, the position of the connector 16B can be predicted more accurately.

As a result, even when it is difficult to secure a sufficient field of view for recognizing the vehicle assembly parts 16 and 18 depending on the arrangement situation of the vehicle parts and the like, the vehicle assembly parts 16 and 18 are recognized and gripped. It will be possible to carry out efficiently.

Then, when the robot grabs the connector 16B, inserts and connects it to the electric device 64, and further fixes the vehicle fixing component 18 to the bracket 66, as shown in FIG. 11, the wires harness WH connectors 16A, 16B, and the vehicle fixing component 18 are fixed. Is installed in a predetermined position on the vehicle.

According to the wire harness information management system configured as described above, at least one of the plurality of vehicle assembly parts 16 and 18 in the packing form of the wire harness WH is based on the position information 53 stored in the storage unit 52. The position can be specified. This facilitates, for example, the robot's gripping work of the vehicle assembly parts 16 and 18. Further, when assembling at least one of the plurality of vehicle assembly parts 16 and 18 to the vehicle, the other vehicle assembly parts 16 and 18 are based on the shape information 54 of the wire harness WH in the unpacked state. 18 movements, positions, etc. can be predicted. Therefore, the wire harness WH can be assembled to the vehicle while suppressing the vehicle assembly parts 16 and 18 which are the components of the wire harness WH from interfering with the vehicle parts, and the wire harness WH can be automatically assembled. Suitable for.

Further, since the shape information 54 includes the unique information of the actually manufactured wire harness WH, when at least one of the plurality of vehicle assembly parts 16 and 18 is assembled to the vehicle, the wire harness WH is used. Based on the unique information, the movements, positions, etc. of other vehicle assembly parts 16 and 18 can be predicted. Therefore, the wire harness WH can be assembled to the vehicle while more reliably suppressing the vehicle assembly parts 16 and 18, which are the components of the wire harness WH, from interfering with the vehicle parts.

By configuring the configuration to include the image pickup data of the wire harness WH as the unique information, the unique information can be easily acquired.

Further, if the imaged data is imaged after the wire harness WH is manufactured and before it is formed in the package, the data can be such that the peculiar habit of the wire harness WH is remarkably expressed.

Further, since the storage unit 52 is the storage unit 52 of the management server 50, it is only necessary to register the identification code in the tag or the like in the wire harness WH. Therefore, information management becomes easy.

{Modification example}
In the above embodiment, the position information 53 and the shape information 54 are stored in the storage unit 52 of the management server 50. However, in the wire harness module shown in FIG. 2, the tag 12 is stored in a semiconductor memory or the like. The device may be used, and the position information 53 and the shape information 54 may be stored in the tag 12.
