Description

  The present invention relates to an electronic device or the like composed of a linear component and other components, and after the linear component is arranged, the influence of the components arranged around the linear component on the linear component is affected by the electronic device. The present invention relates to a linear part interference verifying apparatus and a verifying method thereof that can be verified before production and the like. Also, a linear part design apparatus having a linear part interference verification function capable of verifying, at the design stage, the influence of parts arranged around the linear part on the linear part after the linear part is disposed, and It relates to the design method.

  Electronic devices and the like are composed of many parts including parts that need wiring, and it is necessary to wire the parts with electric wires or cables. In order to perform these wiring operations smoothly at the manufacturing site, in general, the wiring route of these wirings is determined in advance and a wiring work instruction sheet is created, and the wires and cables are cut to a required length. The line parts for wiring are manufactured. At the manufacturing site, wiring work is performed using the linear parts and wiring work instructions.

On the other hand, the structure of electronic devices, etc., and the arrangement of parts are often designed using a three-dimensional CAD system. In the harness design for manufacturing the above-mentioned linear parts, etc., 3 A dimensional CAD system is used. In the harness design using this three-dimensional CAD system, the determination of the wiring route between components such as linear components is performed using three-dimensional geometric shape data representing the structure of the product and the arrangement of the components.

If it is determined that the contact or approach of the linear part to the part is prohibited, an arrangement prohibition space that is an area where the contact or approach of the linear part is prohibited is calculated, and 3 The data is stored in the storage unit 14 as the linear part disposition prohibition space data 14d which is dimension data (S1).

  For example, in the case of the electronic component 305 shown in FIG. 6 whose surface is entirely made of metal, when the outer skin of the linear component comes into contact with the electronic component 305, the outer skin is worn and the linear component is cut. There is a possibility of short circuit. Therefore, it is determined that the electronic component 305 is prohibited from contacting the linear component. In this case, the disposition prohibition space of the electronic component 305 is a space itself occupied by the external shape of the electronic component 305. Therefore, the disposition prohibition space data uses the disposition position and shape of the component 305 as they are. . Further, in the case of the electronic component 306 that generates heat, it is determined that the approach of the linear component is prohibited. Based on the component data 14b of the electronic component 306, the heat generation state is simulated and the arrangement as shown in FIG. The installation prohibition space 307 is calculated as an installation prohibition space for the electronic component 306.

  For this purpose, the linear part disposition prohibition space calculation program 22 flows through an existing simulation program that simulates a heat generation state based on the part data 14b or an electronic part included in the part data 14b. Based on information such as the frequency and current value of the high-frequency current, it is configured using a function such as a simulation program for simulating the electromagnetic field intensity generated from the electronic component. In this way, the linear part disposition prohibition space calculation program 22 is processed for all the parts used in the board fixing casing 300a, and the calculated disposition prohibition space data is sent to the storage unit 14. Remembered.

  Next, the linear part movable space calculation program 23 calculates a movable space which is a movable range after the linear part is arranged based on the linear part data 14c (S2). As described above, the linear part movable space calculation program 23 includes the linear part data extraction program 23a, the ellipse parameter generation program 23b, and the ellipsoid generation program 23c, and the calculation of the movable space is performed as follows. It is done.

  First, the linear part data extraction program 23a extracts the data of the position information (coordinate data) of the length of the linear part and the connection point to which both ends thereof are connected from the linear part data 14c. Next, the ellipse parameter generation program 23b generates an ellipse parameter based on the length of the linear part and the position information (coordinate data) of the connection point at which both ends thereof are connected. Then, the ellipsoid generation program 23c generates an ellipsoid based on the ellipse parameters, and stores the three-dimensional data of the ellipsoid in the storage unit 14 as the movable space data 14e.

  For example, in FIG. 6, a case will be described in which the movable space of the linear component 304 whose length is L1 and both ends are connected to the connection point P1 on the connector 302 and the connection point P2 on the connector 303 is calculated. FIG. 7 shows only the portion related to the calculation of the movable space of the linear component 304 in FIG. 6 and 7, first, the distance D1 between the two connection points is obtained from the position information (coordinate data) of the connection points at both ends of the linear component. This distance D1 is obtained from the coordinates (X1, Y1, Z1) of the connection point P1 and the coordinates (X2, Y2, Z2) of the connection point P2 as follows.

D1 = {(X1-X2) ² + (Y1-Y2) ² + (Z1-Z2) ² } ^1/2
From this distance D1 and the length L1 of the linear part, the major axis M1 and minor axis N1 of the ellipse are obtained as follows.

M1 = L1
N1 = (L1 ² −D1 ² ) ^1/2
Further, the two focal points of the ellipse are the connection point P1 and the connection point P2, and the center point of the ellipse is the midpoint between the connection point P1 and the connection point P2. Therefore, next, using the above values, an ellipse with the connection point P1 and the connection point P2 as a focal point is formed, and the ellipse is defined around the axis of the straight line connecting the connection point P1 and the connection point P2. To form an ellipsoid 310, which is stored in the storage unit 14 as movable space data 14e. In this manner, the movable space data 14e is generated for all linear parts.

  Next, the interference determination program 24 uses the linear part disposition prohibition space data 14d and the linear part movable space data 14e to check whether there is a portion where the disposition prohibition space and the movable space interfere with each other. Is checked (S3). As a check method, a Boolean operation used in three-dimensional CAD or the like can be used. In the Boolean operation, a portion where a plurality of three-dimensionally displayed spaces overlap each other can be extracted, and a portion where the arrangement prohibition space and the movable space interfere with each other can be found by this extraction. For example, in the above example, as shown in FIG. 6, the movable space 310 of the linear component 304 interferes with the disposition prohibition space of the electronic component 305 whose surface is entirely made of metal, that is, the electronic component 305 itself. The interference portion 313a that interferes with the movable space 310 of the linear component 304 and the disposition prohibiting space 307 of the electronic component 306 that generates heat can be found.

  When the interference part is found in this way (S4), the warning display program 25 selects the optimal warning content and the countermeasure method from the warning and countermeasure method data 14f stored in the storage unit 14 in advance, and Together with the display of the part, as shown in FIG. 8, it is displayed on the display of the output unit 13 (S5). Then, for all the linear parts, it is checked whether or not the processing by the linear part movable space calculation program 23 and the interference determination program 24 has been completed (S6). If not, the process proceeds to S2. Returning and repeating the above operation, if the operation is completed, the operation of the linear part interference verification device 10 is ended.

  According to the linear component interference verification apparatus 10 described above, in the board fixed housing 300a illustrated in FIG. 6, the movable space 310 that is a range in which the linear component 304 can move after being disposed and the linear component 304 are in contact with each other. Alternatively, it is possible to know the presence or absence of interference with the component 305 whose access is prohibited or the arrangement prohibition space 307 of the linear component 304 in the component 306 before the board fixing housing 300a is produced. Accordingly, when the movable part 310 is moved after the linear part 304 is actually wired or the like, the linear part 304 and the part 305 disposed around the linear part 304 as generated conventionally, Problems such as contact with the component 306 can be prevented in advance.

  In the above description, only both ends of the linear component 304 are connected and fixed. However, the method of fixing the linear component is not limited to such a case, and may be semi-fixed in the middle of the arrangement path. For example, as illustrated in FIG. 9, the linear component 504 having a length L <b> 2 is connected at both ends at a connection point P <b> 3 on the connector 500 and a connection point P <b> 6 on the connector 503. However, in addition to this, there is a case where it is semi-fixed so as to be movable along the arrangement path by the holding tool 501 at the holding point P4 and by the holding tool 502 at the holding point P5 in the middle of the arrangement path. . Even in such a case, it is necessary to prevent the occurrence of the same trouble as described above, and therefore, the following coping method can be adopted.

  That is, in FIG. 9, the partial section U1 between the adjacent connection point P3 and the holding point P4, the partial section U3 between the connection point P6 and the holding point P5, and the adjacent holding point P4 and the holding point P5. The partial movable space assumed in each of the partial sections U2 between and is used instead of the above-described movable space.

  As a calculation method of this partial movable space, the adjacent connection points and holding points, or both adjacent holding points are regarded as connection points at both ends of the linear part, and the total value of the distances of the partial sections other than the partial section is calculated. A value obtained by subtracting the length of the linear component is regarded as the length of the linear component, and an ellipsoid is formed. The interior of the ellipsoid is defined as a partially movable space.

  For example, the partial movable space of the linear component 504 in the partial section U1 is calculated as follows. First, from the coordinates of the connection point P3, the holding point P4, the holding point P5, and the connection point P6, the distance D2 between the connection point P3 and the holding point P4, the distance D3 between the holding point P4 and the holding point P5, and the connection with the holding point P5. A distance D4 between the points P6 is obtained. From these values, the partial length L21 of the linear component 504 in the partial section U1 is obtained as follows.

L21 = L2- (D3 + D4)
Therefore, the major axis M2 and minor axis N2 of the ellipse are obtained as follows.

M2 = L21
N2 = (L21 ² −D2 ² ) ^1/2
Then, the two focal points of the ellipse are the connection point P3 and the holding point P4. Using the above values, an ellipse with the connection point P3 and the holding point P4 as a focal point is formed, and a straight line connecting the connection point P3 and the holding point P4. The ellipse is rotated around the axis to form an ellipsoid, and stored in the storage unit 14 as the movable space data 14e in the partial section U1 of the linear component 504. The movable space data in the partial section U2 and the partial section U3 can be obtained in the same manner.

  According to the above countermeasure, even when the linear part is held movably along the arrangement path at a holding point in the middle of the arrangement path, after the linear part is arranged, the partial section of the linear part It is possible to know at the design stage whether or not there is interference between the partially movable space, which is a movable range for each, and the linear component placement prohibited space. Therefore, the same operations and effects as those already described above can be obtained.

  In the linear component interference verification apparatus 10 described above, the linear component data 14c includes information on the outer shape and size of the linear component, and the linear component data extraction program 23a of the linear component movable space calculation program 23 includes The length of the linear component may be corrected based on the outer shape and size of the linear component, and the corrected length of the linear component may be used instead of the length of the linear component. . Further, the linear part data 14c includes information on the outer shape and size of the linear part, and the linear part data extraction program 23a is based on the outer shape and size of the accessory of the linear part. The length of the linear part may be corrected, and the corrected length of the linear part may be used instead of the length of the linear part. By doing in this way, the movable space which is the range which can move a linear component after arrangement | positioning can be calculated | required more correctly.

  For example, as shown in FIG. 10A, in the case of a linear part 400 with a thick coating, when the diameter is R3 and the length is L3, the corrected length L31 is L31 = L3 + R3. As shown in FIG. 10 (b), in the case of a linear part 401 configured by bundling the coverings in a row, assuming that the maximum width of the covering is W4 and the length is L4, the corrected length L41 Is L41 = L4 + W4 × 2. As shown in FIG. 10 (c), in the case of a linear part 402 formed by bundling a coating, if the maximum width of the bundled portion is W5 and the length is L5, the corrected length The length L51 is L51 = L5 + W5 × 2. Further, as shown in FIG. 10D, in the case of a linear part 403 with an attached part, if the maximum width of the attached part in the direction orthogonal to the linear part 403 is W6 and the length is L6. The corrected length L61 is L61 = L6 + W6 × 2.

  Further, in the above-described embodiment, the linear part disposition prohibiting space is calculated by the linear part disposition prohibiting space calculation program 22 from the data 14a of the part prohibited from contacting or approaching the linear part. Yes. However, the linear component interference verification apparatus does not include the linear component disposition prohibition space calculation program 22, and the component data includes not only the data of the component itself from the beginning but also the disposition prohibition space data calculated separately. You may make it provide. In such a case, for example, the 3D CAD apparatus has a simulation program for calculating the arrangement prohibition space data, and when designing with the 3D CAD apparatus, the linear part arrangement prohibition space is designed by the simulation program. After calculating the data, using the design data including the linear part disposition prohibition space data, the linear part interference verification apparatus according to the present invention, which is an apparatus different from the three-dimensional CAD apparatus, causes interference of linear parts. Cases such as verification are conceivable.

<Embodiment 2>
FIG. 11 is a block diagram of the linear part design apparatus 30 according to the second embodiment of the present invention, and FIG. 12 is a configuration diagram of the linear part design program 40 used in the linear part design apparatus 30. Similar to the linear component interference verification device 10 in the first embodiment, the linear component design device 30 includes an input unit 11 composed of a keyboard, mouse, tablet, etc., a CPU unit 12, a display such as a CRT, and a printer. And an output unit 13 and the like, and a storage unit 14 such as a semiconductor memory or a hard disk drive.

  The storage unit 14 is installed with a linear part design program 40 having a function for designing a linear part, and, similarly to the linear part interference verification apparatus 10 according to the first embodiment described above, component data. 14a, component data 14b, and linear component data 14c. However, unlike the linear component interference verification apparatus 10, the linear component data 14c includes position information (coordinate data) of connection points to which both ends of the linear component are connected, but the length of the linear component The length of the linear part is calculated by the linear part design program 40 as will be described later. The storage unit 14 includes an area for storing the linear part disposition prohibition space data 14d and the movable space data 14e, and the linear part disposition prohibition space data 14d and the movable space data 14e. Is also data generated by the linear part design program 40. Although not shown, a three-dimensional CAD program is installed in the storage unit 14, and the above-described component data 14a, part data 14b, and linear part data 14c are stored in the three-dimensional CAD program. It is data designed by using.

  As shown in FIG. 12, the linear part design program 40 installed in the storage unit 14 includes a three-dimensional space display program 21, a linear part placement prohibition space calculation program 22, a design management program 41, and a placement route instruction program. 42, a margin length instruction program 43, a linear part length calculation program 44, a linear part movable space calculation program 23, and an interference determination program 24. The linear part movable space calculation program 23 includes a linear part data extraction program 23a, an ellipse parameter generation program 23b, and an ellipsoid generation program 23c. Among these, the three-dimensional space display program 21, the linear part disposition prohibition space calculation program 22, the linear part movable space calculation program 23, and the interference determination program 24 are the linear part interference verification in the first embodiment described above. This is the same program used in the apparatus 10.

  Next, the linear component design operation of the linear component interference verification apparatus 10 for the board fixed housing 300a performed using the linear component design program 40 will be described. FIG. 13 is a flowchart showing the operation of the linear part design apparatus 30 described above. Also in the second embodiment, the board fixing casing 300a shown in FIG. 14 is the same as the board fixing casing 300a shown in FIG. 6 used in the linear component interference verification apparatus 10 in the first embodiment described above. I will explain.

  First, the linear part design program 40 is activated from the keyboard of the input unit 11 of the linear part interference verification apparatus 30. Then, first, as with the linear component interference verification apparatus 10 in the first embodiment described above, the linear component disposition prohibition space calculation program 22 performs line processing for all the relevant components based on the component data 14b. If it is determined whether contact with or approaching a linear part is prohibited, and if it is determined that contact or approach of a linear part to that part is prohibited, contact or approach of the linear part The arrangement prohibition space which is an area where the prohibition is prohibited is calculated and stored in the storage unit 14 as the linear component arrangement prohibition space data 14d which is three-dimensional data (S11).

  When the calculation of the linear part disposition prohibition space is completed as described above, in the next stage, individual linear parts are designed based on the linear part data 14c (S12 to S14). Here, the design of the individual linear parts is specifically based on the position information (coordinate data) of the connection points to which both ends of the linear parts included in the linear part data 14c are connected. It means that the arrangement route is determined and the length is obtained. For these processes, an arrangement route instruction program 42, a margin length instruction program 43, and a linear part length calculation program 44 are used.

  When the design of the linear part is completed, the movable space of the linear part is calculated and the linear part placement is performed in the same manner as the linear part interference verification apparatus 10 in the first embodiment. The presence or absence of interference is verified using the prohibited space data 14d (S15, S16). For the verification of the presence or absence of interference, the linear component movable space calculation program 23 and the interference determination program 24 are used in the same manner as the linear component interference verification apparatus 10 in the first embodiment described above to verify the presence or absence of interference. Is performed in the same manner as the linear component interference verification apparatus 10. The design management program 41 is used for program process flow control in the above-described linear part design and verification of the presence or absence of interference.

  Next, the above-described linear part design will be described in detail. First, data of individual linear parts is extracted from the linear part data 14c, and the arrangement path of the linear parts is instructed and determined by manual operation by the arrangement path instruction program 42 (S12). For example, in FIG. 14, since the connection point P1 on the connector 302 to which both ends of the linear component 304 are connected and the connection point P2 on the connector 303 are highlighted, manual operation is performed using the mouse. By dragging from the connection point P1 to the connection point P2. Then, the arrangement path of the linear component 304 is displayed linearly.

  Therefore, in order to facilitate the arrangement work of the linear parts 304 in the actual arrangement work, next, the length obtained by adding the extra length to the length of the arrangement path of the linear parts 304 is set. The margin length to be added is designated by the margin length instruction program 43 so as to be the length of the linear component 304 (S13). Specifically, numerical values of a plurality of lengths are displayed in an area not shown in FIG. 14, and any one of them is clicked by manual operation using a mouse. Then, the linear part length calculation program 44 calculates the length of the linear part 304 from the arrangement path length of the linear part 304 and the margin length (S14).

  When the design of the linear component 304 is completed as described above, the length of the linear component 304 and the connection point at which both ends thereof are connected are performed in the same manner as the linear component interference verification apparatus 10 in the first embodiment described above. Based on the position information (coordinate data), the linear component movable space calculation program 23 calculates the linear component movable space (S15). Then, the presence / absence of interference is verified by the interference determination program 24 using the calculated movable space and the linear component placement prohibition space data 14d (S16).

  As a result of verification of the presence or absence of interference, if it is determined that there is interference (S17), the design of the linear component 304 and verification of the presence or absence of interference are performed again (S12 to S16), and these are determined until it is determined that there is no interference. The process is repeated. If it is determined that there is no interference as a result of verification of the presence or absence of interference (S17), the arrangement path of the linear component 304 determined in S12 and the length of the linear component 304 calculated in S14 are stored. The data is stored in the unit 14 as a part of the linear part data 14c (S18). Then, for all the linear parts, it is checked whether the design of the linear parts and the verification process for the presence or absence of interference have been completed (S19). If not, the process returns to S12. If the above operation is repeated and finished, the operation of the linear part design apparatus 30 is finished.

  According to the linear component design apparatus 30 described above, in the board fixed casing 300a shown in FIG. 14, the movable space 310 that is the range in which the linear component 304 is movable after being disposed and the linear component 304 are in contact with each other. Alternatively, it is possible to know at the design stage whether or not there is interference with the part 305 whose access is prohibited or the arrangement prohibition space 307 of the linear part 304 in the part 306, and design the linear part 304 that does not cause interference. Can do. Accordingly, when the movable part 310 is moved after the linear part 304 is actually wired or the like, the linear part 304 and the part 305 disposed around the linear part 304 as generated conventionally, Problems such as contact with the component 306 can be prevented in advance.

  In the above-described linear component design apparatus 30, when the linear component arrangement route is instructed by manual operation in S12, the linear component 304 is arranged from P1 to P2 as shown in FIG. A holder 308 may be provided at the holding point P7 in the middle of the path, and the linear component 304 may be semi-fixed in the middle of the arrangement path. In this case, the linear component 304 is semi-fixed so as to be movable along the arrangement path by the holder 308 at the holding point P7. In FIG. 15, an ellipsoid 311 indicates a movable space between P1 and P7 in this case, and an ellipsoid 312 indicates a movable space between P7 and P2.

  Alternatively, in the above example, as a result of directing the arrangement path of the linear component 304 from the connection point P1 to the connection point P2 in S12 and as a result of determining in S17 that there is interference, the line is again displayed. In this case, the arrangement route of the linear component 304 may be set in the same manner as described above instead of instructing linearly from the connection point P1 to the connection point P2. That is, when the linear component 304 is designed again (S12 to S14), when the arrangement route of the linear component is instructed by manual operation in S12 for the second time, as shown in FIG. Thus, the holder 308 is provided in the middle of the arrangement path of the linear component 304, and the linear part 304 is semi-fixed in the middle of the arrangement path. In this case, if it is determined in S18 that the above countermeasure is no interference, not only the arrangement path and length of the linear component 304 but also the positional information of the holder 308 is stored in the storage unit 14 with the linear component data. Store as part of 14c. By doing in this way, the freedom degree of arrangement | positioning of linear components can be expanded.

  As described above, when the linear component is semi-fixed so as to be movable along the arrangement route in the middle of the arrangement route, the partial movable space calculation method is the linear component interference verification apparatus according to the first embodiment described above. 10 can be performed in the same manner as for the linear component 504.

  Further, in the linear part design apparatus 30 in the above-described second embodiment, unlike the linear part interference verification apparatus 10 in the above-described first embodiment, the storage unit 14 is provided with warning and coping method data 14f. Further, although the warning display program 25 is not included in the linear part design program 40, the storage unit 14 is provided with warning and coping method data 14f in the same manner as the linear part interference verifying apparatus 10, and is linear. The part design program 40 may include the warning display program 25. In this case, in the linear part design apparatus 30 according to the second embodiment, if it is determined that there is interference as a result of the verification of the presence or absence of interference in S17, a warning and a coping method stored in advance in the storage unit 14 From the data 14f, the optimum warning content and coping method are selected and displayed on the display of the output unit 13 together with the display of the relevant part.

  Also, in the linear part design apparatus 30 in the second embodiment, as in the linear part interference verification apparatus 10 in the first embodiment, the outer shape and size of the linear part are added to the linear part data 14c. The linear part data extraction program 23a of the linear part movable space calculation program 23 corrects the length of the linear part based on the outer shape and size of the linear part, and the correction is performed. The length of the linear part may be used instead of the length of the linear part. Further, the linear part data 14c includes information on the outer shape and size of the linear part, and the linear part data extraction program 23a is based on the outer shape and size of the accessory of the linear part. The length of the linear part may be corrected, and the corrected length of the linear part may be used instead of the length of the linear part. By doing in this way, the movable space which is the range which can move a linear component after arrangement | positioning can be calculated | required more correctly.

  Also in the linear part design apparatus 30 in the second embodiment, as in the linear part interference verification apparatus 10 in the first embodiment, the linear part design apparatus has a linear part disposition prohibited space. Instead of providing the calculation program 22, the component data may include not only the data of the component itself from the beginning but also the disposition prohibited space data calculated separately.
