Further, the digital mockup tool 100, the assembly / disassembly evaluation apparatus 200, and the database 501 may be distributed to a plurality of computer apparatuses connected to the network.

  FIG. 2 shows a processing example (steps S10 to S21 and steps S50 to S51) executed by the arithmetic processing unit 130 of the digital mockup tool 100 according to the DMU tool program, and an assembling / disassembling evaluation device according to the assembling / disassessment evaluating program. It is a flowchart which shows the process example (step S30-S45) which the arithmetic processing part 400 of 200 performs.

  First, the arithmetic processing unit 130 of the digital mockup tool 100 controls the input / output unit 120 to read the CAD data of the product from the three-dimensional data file 20, and extracts information on each part constituting the product from the read CAD data. Then, an image of each component is displayed on the display device 30 (step S10).

  When an instruction regarding the assembly / disassembly procedure is input from the input device 40 by the user, the assembly / disassembly procedure setting unit 131 rearranges the data of each part in the order of assembly / disassembly according to the user's instruction. (Step S11).

  Thereafter, the arithmetic processing unit 130 repeats the processes of steps S12 to S20 for each component.

  First, when the part name of the part is input from the input device 40 by the user, the part name setting unit 132 sets the input part name in the part data of the part. (Step S13).

  Next, the arithmetic processing unit 130 causes the display device 30 to display an inquiry as to whether or not to set a part property for the part, and an instruction to the effect that the part property is not set for the part is input from the input device 40 by the user. If so, the process of step S15 is skipped (step S14).

  When a part property (part type, part dimension, part weight, part material, etc.) of the part is input from the input device 40 by the user, the part name setting unit 132 converts the input part property into part data of the part. Set. (Step S15).

  Next, the arithmetic processing unit 130 causes the display device 30 to display an inquiry as to whether or not to check the clearance or the like of the part, and an instruction to the effect that the clearance or the like is not checked for the part from the input device 40. When input by the user, the processing of steps S18 to S19 is skipped (step S16).

  When the user inputs information on clearance check, interference check, and dimension measurement of the part from the input device 40, the clearance check means 134, the interference check means 135, and the dimension measurement means 136 receive the information input by the user. Set to the part data. (Steps S17 to S19).

  In this way, the arithmetic processing unit 130 controls the input / output unit 120 to control the input / output unit 120 for the data of each part to which information such as part name, part property, clearance / interference check and dimension measurement is added. (Step S21).

  Thereafter, when the assembly / disassembly evaluation program is started in the assembly / disassembly evaluation apparatus 200, the arithmetic processing unit 400 of the assembly / disassembly evaluation apparatus 200 controls the input / output unit 300 to The part name data of each part output from the up tool 100 is read from the part name data file 50 (step S30).

  Thereafter, the arithmetic processing unit 400 repeats the processes of steps S31 to S42 for each component.

  First, the component name acquisition unit 411 acquires the component name of the component from the component name data input by the input / output unit 300 (step S32).

  Next, the part property acquisition unit 412 determines whether or not the part property of the part has been set in the input part name data, and if the part property of the part has been set, step S34. Is skipped (step S33).

  If the part property of the part is not set in the input part name data, the part property acquisition unit 412 displays the part property corresponding to the part name of the part acquired in step S32 in the part property file of the database 501. The data is read from 510 and set in the part name data (step S34). As illustrated in FIG. 3, the part property file 510 stores a part name and information on part properties (part type, part dimension, part weight, part material, etc.) corresponding to each part name in association with each other. Has been.

  Next, the assembling / disassessment determining means 413 refers to the clearance classification file 520, the clearance / interference presence / absence / dimension measurement value and the interference presence / absence file 530, and the dimension classification file 540 to determine whether the part can be assembled / disassembled. (Step S35) For parts that cannot be assembled / disassembled, a weighting coefficient to be multiplied by the difficulty of assembly / disassembly is set (step S36).

  Next, the work content acquisition means 414 reads the work content corresponding to the part type of the part acquired in step S34 from the work content file 550 and sets it in the part name data (step S37). As illustrated in FIG. 4, the work content file 550 stores part types and information on work contents (for example, assembly, fastening, wiring, etc.) corresponding to each part type in association with each other.

  Next, the evaluation factor acquisition unit 421 reads the evaluation factor corresponding to the work content and the part property of the part from the evaluation factor file 560 and sets it in the part name data (step S38).

  As illustrated in FIGS. 5 to 8, in the evaluation factor file 560, the component type and the information of the evaluation factor (evaluation item, evaluation value, weighting coefficient, etc.) corresponding to each component type are stored in association with each other. Has been. For example, as shown in FIG. 5, if the work content is a “assemble” part, the evaluation value (work time) “0.2” is unconditionally set as the “basic man-hour”, and the weighting coefficient is “2.0”. is there. Also, if the “maximum dimension” of the part is “less than 5 mm”, the weighting coefficient is “2.0”, the evaluation value (working time) is “0.2”, and the “maximum dimension” of the part is “150 mm or more”. If there is, the weighting coefficient is “2.0” and the evaluation value (working time) “0.6” is set.

  Next, the man-hour calculating means 422 calculates the assembling / disassembling man-hour of the part for each set evaluation factor (step S39). Then, the evaluation score calculation means 423 calculates the difficulty of assembling / disassembling the component by multiplying each calculated man-hour of the component by a weighting coefficient, and calculates the evaluation score according to the calculated difficulty. (Step S40). Here, when there are n evaluation factors, assuming that the assembly / disassembly man-hour for each evaluation factor of the part is Sn and the corresponding weighting coefficient is αn, the difficulty of assembling / disassembling the part (k-th part) Rk is obtained from Equation 1, and an evaluation point Pk for assembling / disassembling the part is obtained from Equation 2 (a deduction from 100 full marks).

Rk = ΣSn × αn (1)
Pk = 100−Rk (2)

Next, the evaluation point category determination unit 431 determines an evaluation point category corresponding to the evaluation score of the part calculated by the evaluation point calculation unit 423 according to the evaluation point category file 570 (step S41). As illustrated in FIG. 9, the evaluation point classification file 570 stores evaluation points and information on evaluation point classifications and color arrangement values corresponding to the evaluation points in association with each other. The evaluation points are classified as “difficult” if the evaluation score is less than 40 points, “slightly difficult” if the evaluation score is 40 or more and less than 70 points, and “easy” if the evaluation score is 70 points or more. The color values are classified as “red” when the evaluation score is less than 40, “yellow” when the evaluation score is 40 or more and less than 70, and “blue” when the evaluation score is 70 or more. For example, if the evaluation score is “39 points”, the evaluation score classification is determined as “difficult” and the color arrangement value is determined as “red”.

  When the evaluation points and the evaluation classifications are determined for each part constituting the product by the processes in steps S31 to S42, the color arrangement editing unit 432 reads out the three-dimensional data from the three-dimensional data file 20 and then reads each part. The three-dimensional data (image data) is edited into a color scheme corresponding to the evaluation point classification (step S43). Then, the arithmetic processing unit 250 controls the input / output unit 120 to output the evaluation result data 250 edited in the color scheme according to the evaluation point classification to the three-dimensional data file 20 (step S44).

  Thereafter, when confirming the evaluation result (step S45), the user confirms the assembling property / disassembling property of the product with the digital mockup tool 100.

  When the assembly / disassembly of the product is confirmed by the digital mockup tool 100, the arithmetic processing unit 130 controls the input / output unit 120 to read the CAD data of the product from the three-dimensional data file, and the product from the read CAD data. Is extracted, and an image of each part is displayed on the display device 30 (step S50).

  FIG. 10 shows an example of a screen displayed on the display device 30 in step S50. In FIG. 10, among the parts 61A, 61B, 62, 63, and 64, the parts 61A, 61B, and 64 are colored with a color scheme value “blue” with the evaluation point classification shown in FIG. In the example, the point classification is “slightly difficult” and the color is assigned with the color scheme value “yellow”, and the component 64 is displayed with the evaluation score classification “difficult” and the color scheme value “red”.

  Thereby, the user can reconfirm the assembly / disassembly procedure / clearance / interference / dimensions for the parts whose parts color scheme is changed for each evaluation category (parts with low evaluation points) (step S51). .

  The image of each component displayed on the display device 30 based on the CAD data can be displayed not only in two dimensions but also in three dimensions. In addition, by performing operations such as rotation and movement with the digital mockup tool 100, detailed clearance / interference check is performed, as well as whether the product can be assembled / disassembled, assembly / disassembly procedures, assembly / disassembly difficulty level A detailed study can also be conducted. That is, by moving and rotating a part in two dimensions or three dimensions, it is possible to see a specific movement of each part in an assembly / disassembly process that cannot be understood from a two-dimensional drawing in a stationary state. Furthermore, it is possible to record the motion of the parts as moving image data when examining whether the product can be assembled / disassembled, assembling / disassembling procedures, and the difficulty of assembling / disassembling. The moving image data created by the digital mockup tool 100 can be recorded, for example, in an AVI (Audio Video Interleave) format or MPEG format file, so that the recorded moving image data can be reproduced later. It is. In addition, this digital mockup tool can record not only the moving image data but also a two-dimensional JPEG or PNG format file based on CAD data.

  As described above, according to the assembling / disassembling evaluation apparatus and assembling / disassembling evaluation program in the present embodiment, the subjective and qualitative information by the person in charge is added to the evaluation factor, and the product Can be evaluated quantitatively and objectively. Further, it is possible to easily perform quantitative and objective evaluation of the assemblability / decomposability of the product without depending on the experience (subjectivity) of the person in charge.

  In addition, since the display color of the component is colored according to the evaluation score of assembling / disassembling for each component, it is possible to easily recognize visually whether the assembling / disassembling is possible or the difficulty evaluation result.

  As mentioned above, although embodiment of this invention was described in detail, this invention can be implemented in other various forms, without deviating from the mind or main characteristics.

  For example, by appropriately changing the setting value of the evaluation score category file 570, the color scheme of the components of all evaluation score categories can be changed to a color scheme corresponding to the evaluation score category, or the evaluation score is less than 40 points (evaluation score category “difficult” ), You can change the color of the parts only to “red”.

  In the flowchart shown in FIG. 2, the processing (steps S30 to S45) in the assembling / disassembling evaluation apparatus 200 is collectively performed (through) from the processing in the digital mockup tool 100 (steps S10 to S21). Although the example of performing was demonstrated, you may make it work separately, so that each function can be started independently.
