DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
First, the bending extension process, the twist process, and the replacement process, which are the basis of the present invention, will be described with reference to FIG. 2 (A), 2 (B), and 2 (C) are diagrams showing basic processes related to a bending extension process, a twisting process, and a replacement process, respectively.
[0019]
As shown in FIG. 2 (A), in the bending extension process, the trunk line S1 and the branch lines S2, S3 constituting the wire harness are bent in the direction of their roots as indicated by arrows in the drawing. The This root corresponds to the position where the restraining members C1, C2, C3 in the wire harness are attached and the branch points B1, B2. Here, as the restraining members C1, C2, and C3, for example, a clamp is assumed. In this bending extension process, the wire harness is still in a three-dimensional shape.
[0020]
Further, as shown in FIG. 2B, in the twisting process, the trunk line S1 constituting the wire harness has a branch line S2 branched at a branch point B as shown by an arrow in the drawing on a reference plane described later. Twisted like The restraining members C1, C2, and C3 are as described above.
[0021]
Further, as shown in FIG. 2C, in the replacement process, the attachment position of the branch line S2 constituting the wire harness is changed as indicated by an arrow in the drawing. At this time, the branch line S2 branched from the trunk line S1 at the branch point B is changed in the circumferential position of the trunk line S1 so as to be on a reference plane described later. The restraining members C2 and C3 are as described above. In addition, in this specification, the trunk line and the branch line are provided for convenience, and instead of this, other methods such as the first line, the second line, and the like may be used.
[0022]
A combination of these bending extension processing and torsion processing or replacement processing is further combined to convert the wire harness given as three-dimensional data into two-dimensional data, that is, two-dimensionally developed and output. In this way, the wire harness can be developed two-dimensionally while being a very simple method. Therefore, an accurate jig plate design for manufacturing the wire harness can be easily performed in a short period of time. In particular, by combining the replacement process, the degree of freedom in designing the jig plate is further expanded.
[0023]
The bending extension process, the twist process and the replacement process can be realized using hardware as shown in FIG. FIG. 3 is a block diagram showing a hardware configuration for realizing the present invention.
[0024]
As shown in FIG. 3, the hardware for realizing the present invention includes a microcomputer 11, an input device 12, a display device 13, a printing device 14, a storage device 15, a communication interface 16, and a read / write device 17. An information processing apparatus such as a desktop computer is used. The microcomputer 11 includes a CPU 11a (central processing unit), a ROM 11b that stores a boot program and the like, and a RAM 11c that temporarily stores various processing results. The input device 12 is a keyboard, a mouse or the like for inputting the above values, the display device 13 is a CRT or the like for displaying the processing results, and the printing device 14 is a printer for printing the processing results. The storage device 15 is a hard disk drive or the like that stores application programs, processing results, and the like according to the present invention. The communication interface 16 is, for example, a modem board for performing data communication with other devices via a LAN line or the like. The read / write device 17 is a device that reads three-dimensional data stored in a portable recording medium such as a known CD-ROM, and writes the two-dimensional data generated by this device to the portable recording medium. Each of these components is connected via an internal bus 18. The CPU 11a is activated according to a boot program stored in the ROM 11b, and operates according to an application program indicating a processing procedure according to the present invention. A processing procedure according to this embodiment performed using such hardware and an output example thereof will be described below with reference to FIGS.
[0025]
FIG. 4 is a flowchart showing a processing procedure according to an embodiment of the present invention. FIGS. 5A and 5B are flowcharts showing subroutines corresponding to the bending extension process and the twisting process in FIG. 4, respectively. FIG. 6 is a diagram illustrating an example of three-dimensional data before bending extension processing. FIG. 7 is a diagram for explaining a bending extension process. FIG. 8 is a diagram for explaining the main line creation processing. FIG. 9 is a diagram for explaining the reference plane. FIG. 10 is a diagram for explaining the twisting process. FIG. 11 is a diagram illustrating an example of two-dimensionally developed data.
[0026]
In step S1 shown in FIG. 4, three-dimensional data is read. The three-dimensional data is data that is created assuming a three-dimensional space designed based on the actual mounting shape of the wire harness, for example, via a portable recording medium such as a CD-ROM or a network such as a LAN. Provided. It should be noted that initialization of data necessary for the subsequent processing is also performed here.
[0027]
In step S2 and step S3, a node and a constraint point are set. That is, the given three-dimensional data includes a corrugate, a terminal, an exterior, etc. in addition to a clamp and a protector as a restraining member assumed in the present invention. Are irrelevant, they are automatically deleted, and three-dimensional data as shown in FIG. 6 is automatically generated. Steps S1 to S3 and related hardware correspond to initial condition setting means in the claims.
[0028]
In FIG. 6, this wire harness is comprised from trunk line s1a-s1f and branch line s3-s7, and the clamp shall be attached to each front-end | tip as restraint member c1-c7. b1 to b5 indicate branch points of the trunk line and each branch line, and a protector as a restraining member p1 for fixedly restraining the branch direction of the trunk lines s1e and s1f and the branch line s6 is attached to the branch point b5. And
[0029]
By the way, although a restraining direction is fixed in restraint members, such as a clamp and a protector, a twist process may not be applicable depending on the case. In consideration of these, it is possible to give a constraint instruction to an arbitrary node. That is, it is possible to appropriately add, delete, move, and restrict the nodes by manual operation using the input device 12. A node refers to a measuring point that determines a route, such as a restraining member or a branch point. If it is determined in step S3 that these settings have been completed, the process proceeds to step S4 (Y in step S3).
[0030]
Next, in step S4 and step S5, a reference point is set. Here, the reference point is a point that serves as a reference for bending the wire harness. That is, the node is bent from this reference point. The reference point is, for example, a branch point between a line having the maximum diameter and a line having the second largest diameter constituting the wire harness, that is, a node. When both diameters are equal, priority is given to the one with many electric wires to comprise. Furthermore, when both the number of electric wires is equal, the fact is output to the display device 13. In this case, either can be selected by manual operation such as mouse click of the node by the input device 12. If it is determined in step S5 that these settings have been completed, the process proceeds to step S6 (Y in step S5). Note that Step S4, Step S5, and related hardware correspond to the reference point setting means in the claims.
[0031]
Next, in step S6, bending extension processing is performed. This will be described with reference to FIGS. 5A and 7. The segment sg11 is linearly extended from the node n1 set as the reference point to the next node n2 (steps S601 and S602). N). However, the extending direction follows the direction vector v1 indicating the restricting direction based on the restricting member and the restricting instruction. The direction vector is the direction in which the root of the related segment is facing. A segment refers to a line connecting adjacent nodes.
[0032]
In step S603, when the next node is reached, if the node indicates an end point, the bending extension process ends (Y in step S603), and if the node indicates a constraint point, the direction is toward the constraint direction. If the node indicates a branch point, the direction is changed (N in step S603, N in step S604, Y in step S606), whichever Otherwise, the current direction is maintained (N in step S603, N in step S604, N in step S606), and the bending extension process is continued.
[0033]
By such bending extension processing, the shape shown on the left side of FIG. 7 is converted into the shape shown on the right side. In the above bending extension process, the segments sg11 and sg23 are extended on a plane α including both direction vectors v1 and v2, and the segments sg11 and sg25 are included in a plane β including both direction vectors v1 and v3. It is extended as follows. Note that step S6 and related hardware correspond to bending extension processing means in claims.
[0034]
When the bending extension process is completed, the trunk line is created in steps S7 and S8. That is, as shown in the left side of FIG. 8, the segments sg12, sg23, and sg34 as the trunk lines are selected for the segments sg12, sg23, sg25, sg34, and sg34 that have been subjected to the bending extension process, as shown in the right side of the drawing. These are then aligned. In other words, the segment sg23 having a larger diameter is selected from the segments sg23 and sg25 branched at the node n2 in the segment sg12 having the maximum diameter so as to be aligned with the segment sg12. Similarly, the segment sg34 having a larger diameter is selected from the segments sg34 and sg36 branched at the node n3 in the selected segment sg23 so as to be aligned with the segment sg23. The straightening is performed in a similar manner before the node 4. If it is impossible to make the selection automatically, the input device 12 can be used to make an arbitrary selection. Moreover, priority is given to the segment previously commanded as a trunk line. A segment that has not been selected as a trunk line is subjected to coordinate conversion while maintaining a branch angle with the segment that has become a trunk line. If it is determined in step S8 that these settings have been completed, the process proceeds to step S9 (Y in step S8). Note that Step S7, Step S8, and related hardware correspond to the main line creation means in the claims.
[0035]
In steps S9 and S10, a reference plane is created. That is, as shown in FIG. 9, a reference plane R is created for the three-dimensional data in which the straightening of the trunk line has been completed as shown in FIG. The reference plane R is automatically created so as to include, for example, a segment sg12 having the maximum diameter and a segment sg25 having the second largest diameter that constitute the wire harness. In this case, however, it is possible to use the input device 12 so as to include an arbitrary segment, or to slightly rotate the automatically created reference plane as indicated by an arrow in the figure. If it is determined in step S10 that these settings have been completed, the process proceeds to step S11 (Y in step S10). At this stage, some segments are not included in the reference plane and are still three-dimensional data. Steps S9 and S10 and related hardware correspond to the reference plane creating means in the claims.
[0036]
Next, in step S11, a twisting process is performed. This will be described with reference to FIG. 5B and FIG. 10. A branch point is searched for along the trunk line set in step S7 (step S111). When the search reaches the next node, the search is continued unless the node is a branch point (N in step S112, N in step S113). When the next branch point, for example, the node n3 is searched (Y in step S112, Y in step S113), the segment sg36, which is a branch line branched from the node n3, is a trunk line so as to get on the reference plane R. The segment sg23 is twisted by a predetermined angle θ (step S114). If this angle θ, that is, the torsion angle is smaller than the reference torsion angle, the torsion processing at this point has succeeded. Therefore, unless this point is the end point, the process returns to step S111 to search for the next branch point (step S115). Y, N of step S116). If the twisting process is successful for all branch points (Y in step S116), two-dimensionalization completion information indicating that fact is output (step S117), and the twisting process is terminated.
[0037]
On the other hand, if the torsion angle is larger than the reference torsion angle (N in step S115), the torsion processing at this point is impossible, so that the two-dimensional stop information indicating that is output (step S118). Further, the node name, that is, the twist stop location information is output (step S119), and the twist process is terminated. The reference torsion angle is, for example, the maximum allowable torsion angle that does not damage the electric wires constituting the wire harness, and can be acquired in advance by a test or the like. Specifically, this angle is about 90 degrees. In the twisting process, points corresponding to nodes are not twisted, and segments between nodes are evenly twisted. 10 denote the same components as those shown in FIG. Step S11 and related hardware correspond to the twist processing means of the claims.
[0038]
When the twisting process is finished, it is determined in step S12 whether or not the two-dimensionalization is completed. That is, if the two-dimensionalization completion information has been output (Y in step S12), the process proceeds to step S13, where the two-dimensional data is displayed on the display device 13, and the series of processing ends. On the other hand, if the two-dimensionalization stop information is output (N in Step S12), the process proceeds to Step S14, and the display device 13 displays the stop information and stop point information indicating that. And it progresses to step S14 and a replacement process is performed. Note that the two-dimensional data and the result display may be printed out not only from the display device 13 but also from the printing device 14. Such processing makes it possible to more accurately deploy the wire harness two-dimensionally. Therefore, a more accurate jig plate design can be performed.
[0039]
In step S15 and step S16, a replacement process is performed. That is, the attachment position in the circumferential direction of the segment sg23 that is the trunk line is changed so that the segment sg36 that is the branch line in FIG. In this replacement process, the segment sg23 is not twisted. If it is determined in step S16 that the replacement process has been completed (Y in step S16), the process returns to step S11 and the twisting process is performed again. That is, based on the shape after the replacement process, the determination as to whether or not torsion is possible is performed again. Then, in step S12, such a replacement process can be repeated until it is determined that the two-dimensionalization is completed. Note that Step S15, Step S16, and related hardware correspond to a replacement processing means in claims. Such replacement processing enables two-dimensional development that was impossible with twist processing. Accordingly, the degree of freedom in designing the jig plate is expanded.
[0040]
Then, the two-dimensional data, that is, the two-dimensionally expanded data as shown in FIG. 11 is output on the display device 13 through the bending extension process, the twisting process, and the replacement process as described above. The In addition, although the reference code | symbol attached | subjected in FIG. 11 shows the component equivalent to the reference symbol attached | subjected in FIG. 6, the component was coordinate-transformed by each process. The two-dimensionally developed data may be printed out by the printing device 14 or stored in a CD-ROM or the like by the RW device 17. Further, it may be transferred to another apparatus using the communication I / F 16 and a LAN.
[0041]
As described above, according to the above-described embodiment, two-dimensional development of the wire harness can be basically performed by a simple process including only a bending extension process and a torsion process or a replacement process. Therefore, an accurate jig plate design for manufacturing the wire harness can be easily performed in a short period of time.
[0042]
Note that the above processing may be provided with a partial selection function, and an arbitrary line or a plurality of lines may be selected and two-dimensionally developed. Moreover, this invention is not limited to the wire harness mounted in a vehicle, It is applicable also to the wire-like structure of the same structure as this. The present invention can be modified as appropriate without departing from the spirit of the present invention.
