Description

  The present invention mainly relates to a packing form examination support device for examining a packing form of a wire harness on a 3D virtual space.

  When an automobile wire harness is delivered to a customer as a product, the wire harness is stored and shipped in a packing box (polytena), for example, in a spirally wound state. Conventionally, the package (packaging form) of this wire harness has been verified by the actual product.

On the other hand, the design of the wiring path of the wire harness has been shifted to one using computer-aided design (CAD). Patent Document 1 discloses a wire harness route design support device using a CAD device, and it is assumed that wiring harness routing design can be performed thereby.
Japanese Patent Laid-Open No. 2004-172088

  The packaging form of the wire harness is determined by trial and error using the actual product so that the number of storages per packing box can be increased and the delicate parts are not laid under heavy parts. In addition, the wire harness may be bent in advance in consideration of workability at the time of assembly. In this case, the packaging form must be determined so that the bent hook portion is not stretched or bent. Furthermore, it is necessary to consider the handling so that the worker can easily lift the wire harness.

  Conventionally, when deciding the packaging form of a wire harness, the above-mentioned multiple requirements have been studied many times through exchanges using the actual product between the manufacturing side and the customer side, so a long examination period is required. It was. Moreover, since the actual wire harness is required for the examination, the examination cannot be started unless it is in the later stage of the design, and it has been difficult to follow the vehicle development schedule that has been accelerated. There was also a demand to abolish useless manufacturing for environmental measures.

  It is considered that such a problem can be solved by performing the examination on a 3D virtual space by CAD. However, Patent Document 1 does not disclose anything about the examination of the packaging form of the wire harness. In addition, the configuration of Patent Document 1 corrects a route of a wire harness whose route is fixed to a certain degree in advance, and cannot be applied to the examination of a packaging form in which such a route cannot be assumed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing a schematic configuration of a computer (personal computer) 1 which is a wire harness packing form examination support apparatus according to the present embodiment. The computer 1 includes a display (display unit) 10 and an operation unit 13.

  The display 10 is configured by a monitor capable of color display, such as a liquid crystal monitor or a CRT monitor. The operation unit 13 includes a keyboard 11 and a mouse 12.

  FIG. 2 shows a device block diagram of the computer 1. The computer 1 includes a CPU (Central Processing Unit) 14, a RAM (Random Access Memory) 15, and an HDD (Hard Disk Drive) 16, and is connected to the display 10, keyboard 11, and mouse 12 through an internal bus 17. ing.

  The HDD 16 stores a packing form examination support program that implements a series of functions to be described later by performing an installation operation using an appropriate storage medium. The CPU 14 reads the program on the HDD 16 onto the RAM 15 when an instruction to execute the program is given by the operator. The CPU 14 is configured to receive input from the keyboard 11 and the mouse 12, execute a program on the RAM 15 based on the input, and display the execution result on the display 10.

  Next, with reference to FIG. 3, the examination of the packaging form of the wire harness using the computer 1 of this embodiment is demonstrated. FIG. 3 is a flowchart showing the flow of the wire harness packing form examination method in which the packing form is actually examined using the computer 1.

  When the operator executes the wire harness packing form examination support program on the computer 1, first, the ASSY board is reproduced in order to model the wire harness in a three-dimensional virtual space (S101).

  The ASSY board is an assembly board for manufacturing a wire harness. The operator refers to the ASSY diagram of the wire harness to be considered for the packing form, and on the virtual ASSY board displayed on the display 10, the shape of the wire harness (branches, diameter of each part, etc.) and exterior parts By specifying the type and position (corrugated tube, tape, clamp, protector, etc.), a temporary model of a virtual wire harness is constructed. Thereby, the wire harness is modeled as three-dimensional data that can be expressed in the three-dimensional virtual space.

  The temporary model constructed in this way does not have a data structure suitable for deforming like a wire harness. Therefore, in the present embodiment, by creating (softening) the ring-cut data in S102, a wire harness model suitable for deforming like a wire harness with a simple data structure and a small amount of calculation is constructed.

  FIG. 4 shows a conceptual diagram of the wheel cut data created in S102. FIG. 5 is a functional block diagram showing the relationship between each function of the program of the present embodiment and various data. In creating the cut-out data, the wire harness model construction unit 30 constructs the wire harness model 2 as shown in FIG. 4 based on the information of the temporary model 24 described above. The wire harness model 2 has a structure in which a plurality of short cylindrical bodies 20 that are rigid bodies are arranged side by side in the axial direction, and adjacent cylindrical bodies 20 are connected to each other by a movable joint 21. In the movable joint 21, a joint that performs X-axis rotation and a joint that performs Y-axis rotation are alternately arranged, whereby the wire harness model 2 can be freely deformed.

  As shown in FIG. 5, the wire harness model 2 includes one centroid 25, a plurality of cylindrical bodies 20, and a movable joint 21 as data. Each cylindrical body 20 has coordinate data 40 described in a local coordinate system with the center of gravity 25 as the origin, as well as component data 41 indicating the presence / absence of an exterior component (if any), harness diameter data 42, Information such as the own weight data 43 can be set. The movable joint 21 can be set with bending limit data 44 that defines the movable range of the movable joint 21. The center of gravity 25 includes a conversion matrix for converting the local coordinate system of the cylindrical body 20 into the world coordinate system.

  The component data 41, the diameter data 42, and the own weight data 43 are automatically set to the respective cylindrical bodies 20 by the wire harness model construction unit 30 when creating the wheel cut data. That is, since the diameter of each part and the position of the exterior part are specified for the temporary model 24 created in S101, the wire harness model construction unit 30 creates the wire harness data from the data of the temporary model 24. These data are automatically set in the cylindrical body 20 created at the corresponding position of the model 2.

  The bending limit data 44 can be manually set by an operator, but in the present embodiment, the bending limit automatic setting unit 32 automatically sets the bending limit data 44 for each movable joint 21. For this purpose, first, a curvature table 46 describing a bending limit (curvature) according to the harness diameter and the type of exterior part is created in advance and stored in the HDD 16. At the time of creating the wheel cut data, the curvature table is read based on the part data 41 and the diameter data 42 set in the cylindrical body 20 adjacent to the movable joint 21, and the corresponding curvature data is read out. Appropriate bending limit data 44 is automatically set for the movable joint 21.

  As a result, for example, a portion with a small diameter can be bent greatly, and a portion with a large diameter portion or an exterior part (deformable one such as a corrugated tube or split tube) cannot be bent so much. The wire harness model 2 can realize deformation close to a real wire harness.

  Further, in the present embodiment, it is possible to set the bending prohibition section 23 in the wire harness model 2. Further, the bending prohibition section 23 can be automatically performed by the bending prohibition section automatic setting unit 31 at the time of creating the ring cutting data.

  For example, in the creation of the wire harness temporary model 24 in S101, it is assumed that a non-deformable component such as a band clamp is disposed at a predetermined position of the wire harness. When the wheel cut data is created in S102 based on this temporary model, the cylindrical body 20a created in the portion where the wire harness is arranged has a length as shown in FIG. Is adjusted. That is, the cylindrical body 20a is adjusted to have the same length as the length of the section where the band clamp 22 fixes the wire harness.

  Thereby, since the movable joint 21 is not provided in the section of the cylindrical body 20a, the wire harness model 2 cannot be bent in this section. In this way, the bend prohibition section 23 can be automatically set, and the influence of a non-deformable part such as a clamp can be reproduced in a more realistic state.

  As described above, when the cut data is created and the wire harness model 2 is constructed, the additional setting of the bending prohibited section is set in S103. That is, when a portion where the bending prohibited section cannot be automatically set or an incorrect bending prohibited section is set, the operator manually sets or resets the bending prohibited section (S104).

  For example, when a protector having a complicated shape is arranged on the wire harness, there is a case where the bending prohibited section cannot be automatically set as described above. In addition, for the convenience of assembly, there are cases where it is desired to set a part where a curl is attached in advance or where a curl is not desired. In such a case, the operator manually sets a bending prohibited section in an arbitrary section.

  Specifically, the operator operates the operation unit 13 to select a section where bending prohibition is to be set, and reconstructs the wire harness model 2. Then, the movable joint 21 is deleted from the section so that the deformation is impossible, and this section becomes a bending prohibited section. In addition, the bending-prohibited section can be released. In this case, an appropriate number of movable joints 21 are inserted into the section designated by the operator at appropriate intervals, and deformation is possible.

  When the setting of the bending prohibition section is completed, the packaging box model 3 is selected and displayed (S105). This packing box model 3 is obtained by modeling a packing box used for accommodating a real wire harness as three-dimensional data that can be expressed in a three-dimensional virtual space, and includes shape data 47 and coordinate data 48. . In addition, a plurality of packaging box models having different sizes and shapes are prepared in advance. Therefore, the operator can plan and verify the packing form in various sizes and shapes of packing boxes, and can determine an optimal packing box. The operator selects a desired packing box model and displays it on the display 10.

  FIG. 6 shows a state where the wire harness model 2 and the packaging box model 3 are displayed on the display 10. As shown in FIG. 6, the computer 1 renders the wire harness model 2 and the packaging box model 3 in the three-dimensional virtual space so as to be projected on a virtual screen of two-dimensional coordinates, and displays the rendering result on the display 10. can do. Further, by operating the operation unit 13, enlargement / reduction and change of viewpoint can be freely performed.

  As shown in FIG. 6, the wire harness model 2 can display smoothly without being aware of the cylindrical body and the movable joint, and can reproduce the difference in branching and diameter, etc. . In addition, the location where the exterior parts such as corrugated pipes are arranged can be displayed in a specific color (hatched hatching in the figure), and the special display 50 visually recognizes the location where the curvature is different. can do.

  The packaging box model 3 can be switched between display and non-display, and when set to non-display, it is displayed in a wire frame shape as shown in FIG. As a result, the wire harness model 2 is not obstructed by the packing box model 3 and can no longer be seen.

  While viewing the display on the display 10, the operator rotates and moves the wire harness model 2 so as to be in a position suitable for storage in the packaging box model 3 (for example, a position immediately above the packaging box model 3) ( S106). This operation can be performed using the keyboard 11 or can be performed intuitively by operating the mouse 12 to move the mouse pointer 51 and performing a so-called drag operation. When this movement and rotation are performed, the transformation matrix 45 of the center of gravity 25 is updated as appropriate and reflected in the wire harness model 2. Rendering is performed each time the wire harness model 2 is changed, and the display content of the display 10 is updated each time.

  Next, the operator bends the wire harness model 2 and deforms it so that it can be stored in the packing box model 3 (S107). This deformation operation can also be performed by a drag operation of the mouse 12, for example, as in the above case. When each part of the wire harness model 2 is deformed by this operation, the coordinate data 40 of each cylindrical body 20 is appropriately updated and reflected in the wire harness model 2.

  The deformation of the wire harness model 2 at this time is affected by the bending limit data 44 and the bending prohibited section. That is, the portion where the bending prohibition section is set cannot be deformed, and the minimum bending radius of each portion is regulated based on the bending limit data 44.

  Thereby, it is not bent by an operator's operation so that it cannot be a real wire harness, or a portion that should not be bent is not bent. Accordingly, it is possible to operate the wire harness model 2 as if using an actual product and to search for an optimal packing form.

  Moreover, in this embodiment, the deformation | transformation by the dead weight reproduction | regeneration part 33 has reproduced the deformation | transformation by the dead weight of a wire harness. Specifically, the self-weight deformation reproducing unit 33 calculates the force applied to each cylindrical body 20 based on the self-weight data 43 set for each cylindrical body 20, and automatically deforms the wire harness model 2. Thereby, for example, the bending due to the weight of the wire harness that is spirally wound can be reproduced.

  When the wire harness model 2 is completely deformed and stored in the packaging box model 3, the interference detection unit 34 performs an interference check (S108). When the interference check is executed, the interference detection unit 34 performs an appropriate calculation based on the wire harness model 2 and the packaging box model 3 and inspects whether or not the wire harness model 2 is normally within the packaging box model 3. To do. When the interference detection unit 34 detects the interference between the wire harness model 2 and the packaging box model 3, the interference portion is highlighted on the display 10.

  When the interference is detected (S109), if the wire harness model 2 can be further deformed (S110), the operator continues the bending work so that the wire harness model 2 is properly fitted in the packaging box model 3 ( S107). If the wire harness model 2 can no longer be bent despite the interference detected, the process returns to the selection of the packing box model (S105), and the packing box having the optimum shape is selected again.

  When the interference is not detected and the work of storing the wire harness model 2 in the packaging box model 3 is completed, the validity of the packaging form is examined. For example, it is considered whether a delicate part is not an underlay or is in a form easy for the operator to lift. In FIG. 6, only one wire harness model 2 is shown, but two or more wire harness models 2 can be displayed at the same time, and each can be moved and deformed. The packing form can be examined in a state of stacking.

  In addition, when the plurality of wire harness models 2 are arranged in the packing box model 3 and the packing form is examined in this way, the interference detection unit 34 can perform an interference check between the wire harness models 2. That is, the interference detection unit 34 performs an appropriate calculation based on the plurality of wire harness models 2 and inspects whether there is interference between the wire harness models 2. When interference is detected, the interference location is highlighted on the display 10. Based on this, the operator can move and deform each wire harness model 2 to examine an optimum packing form.

  Furthermore, since the viewpoint can be changed and the display of the packaging box model can be freely changed, it is possible to examine in detail the parts that cannot be confirmed due to the blind spots in the examination using the real thing.

  The packaging form thus determined can be output as, for example, three-dimensional digital data. Therefore, for example, when exchanging with a distant customer, the examination is smoother than the exchange using the real product. In addition, a packing form specification sheet is created based on the determined packing form. By using the rendering drawing output from the computer 1 at this time, an accurate and easy-to-understand packing specification sheet can be easily obtained. Can be created.

  As described above, the computer 1 that is the wire harness packing form examination apparatus in the present embodiment includes the display 10 and the operation unit 13. The display 10 displays a packaging box model 3 and a wiring harness model 2 in which the packaging box and the wire harness are reproduced in a three-dimensional virtual space. The operation unit 13 is operated by an operator to move and deform the wire harness model 2.

  As a result, it is possible to examine the packing form without producing the actual product, so that it is possible to conduct a smooth examination by exchanging digital data between the manufacturing side and the customer side, and it is possible to eliminate unnecessary manufacturing. . Moreover, since the time for manufacturing the actual product can be saved, a lot of time can be allocated for the examination of the packing form, and a wide variety of examinations are possible. In addition, the packing form can be examined from an early stage of development, and the development schedule can be shortened.

  In addition, the computer 1 of the present embodiment includes a wire harness model construction unit 30 that reproduces a wire harness with a structure in which a plurality of cylindrical bodies 20 are connected by a movable joint 21.

  As a result, the movement and deformation of the wire harness can be reproduced with a simple process and data structure, so that the packing form in the three-dimensional virtual space can be examined with a small amount of calculation.

  In the computer 1 of the present embodiment, the wire harness model 2 can include bending limit data 44 relating to the bending limit of the wire harness model 2, and the deformation of the wire harness model 2 by the operation unit 13 is bent. It is regulated based on the limit data 44.

  Thereby, since it becomes impossible to bend the wire harness model 2 beyond a predetermined bending limit, the deformation | transformation like a real wire harness can be reproduced.

  In addition, the computer 1 of the present embodiment includes an automatic bending limit setting unit 32 that can automatically determine the bending limit data 44 based on information related to the wire harness.

  As a result, deformation closer to that of the actual wire harness can be reproduced, so that the examination result of a highly reliable packaging form can be obtained. Further, since the labor of manually setting the bending limit data 44 in the wire harness model 2 can be saved, work efficiency is improved.

  In the computer 1 of the present embodiment, the wire harness model 2 can be set with a bending prohibited section, which is a section where bending is prohibited. In the bending prohibited section, the wire harness model 2 by the operation unit 13 is set. Deformation is prevented.

  Thereby, a packing form can be examined considering the case where a wire harness cannot be bent on account of assembly. Moreover, since the state where the parts which cannot be bent are attached can be reproduced, the packaging form closer to the actual wire harness can be examined.

  Moreover, the computer 1 of this embodiment is provided with the bending prohibition area automatic setting part 31 which can set a bending prohibition area automatically based on the information regarding a wire harness.

  This saves the trouble of manually specifying the bending-prohibited section, thereby improving work efficiency.

  In addition, the computer 1 according to the present embodiment can set the bending prohibited section in the wire harness model 2 by operating the operation unit 13.

  Thereby, for example, when it is desired to prohibit bending of a specific section in consideration of assemblability and the like, an operator can manually cope with it.

  In addition, the computer 1 of the present embodiment includes a self-weight deformation reproducing unit 33 that automatically reproduces deformation due to the self-weight of the wire harness model 2.

  Thereby, the packing form closer to the actual wire harness can be reproduced.

  In addition, the computer 1 according to this embodiment includes an interference detection unit 34 that detects interference between the wire harness models 2 and interference between the wire harness model 2 and the packaging box model 3.

  Thereby, it can be easily confirmed whether or not the wire harness can actually be accommodated in the packaging box, whether or not the plurality of wire harnesses are accommodated in a state where they are forcibly contacted.

  Further, the wire harness packing form examination support program of the present embodiment includes a model display function for displaying on the computer 1 a packing box model 3 and a wire harness model 2 in which the packing box and the wire harness are reproduced in a three-dimensional virtual space. A movement deformation function for moving and deforming the wire harness model 2 according to the operation is realized.

A movement deformation step of moving and deforming the wire harness model 2 by operating 1.

  As a result, it is possible to examine the packing form without producing the actual product, so that it is possible to conduct a smooth examination by exchanging digital data between the manufacturing side and the customer side, and it is possible to eliminate unnecessary manufacturing. . Moreover, since the time for manufacturing the actual product can be saved, a lot of time can be allocated for the examination of the packing form, and a wide variety of examinations are possible. In addition, the packing form can be examined from an early stage of development, and the development schedule can be shortened.

  Although the preferred embodiment of the present invention has been described above, the above configuration can be changed as follows, for example.

  The wire harness packing form examination support device can be realized by dedicated hardware instead of the configuration of the personal computer.

  The operation unit 13 is not limited to the keyboard 11 and the mouse 12, and various input devices such as a trackball and a touch panel can be used.

  The wire harness temporary model 24 can be created by reading CAD data created at the design stage. Further, the wire harness model 2 may also read the circular three-dimensional data created by the external program instead of the configuration constructed by the wire harness model construction unit 30.

  For example, instead of the configuration in which the length of the cylindrical body 20 is changed or the movable joint 21 is deleted, the bending prohibited section is set by setting a movable prohibition flag for each movable joint 21 in the bending prohibited section. It can also be realized by prohibiting (locking) movement.
