Description

The present invention relates to a design support device and a design support method.

The task of assembling parts provided in an assembly kit into a single assembly is difficult for inexperienced beginners. During assembly work, if the assembly sequence, in particular which parts are to be assembled in which order, is not done in a planned manner, physical interference between parts may result in rework of the work.

Therefore, Patent Document 1 describes an assembly sequence generation system that receives information on the arrangement of each component and its proximity relationship with other components and creates an assembly sequence as an animation. This assembly sequence generation system also provides a function for an assembly worker to specify a set of parts to be assembled simultaneously.

Japanese Patent Application Publication No. 2012-014569

As described in Patent Document 1, in the conventional technology, assembly work is supported by directly notifying beginners of information useful for assembly work. However, even if a beginner knows the correct assembly sequence, he or she would still have to perform unfamiliar manual tasks such as tightening screws.
Therefore, as the number of parts increases, costs such as work time required for assembly work increase. Furthermore, poor skill, such as not tightening the screws properly, may result in a poor quality of assembled product.

On the other hand, in order to reduce the burden of assembly work, we will consider reducing the number of parts that make up the assembled product in the first place. In other words, instead of constructing one assembly from a large number of small-grained parts, the same assembly is constructed from a small number of large-grained parts, thereby streamlining the assembly work from the component manufacturing stage.
However, since the conventional technology does not consider how to combine multiple small parts into one large part, it has been difficult to design parts that facilitate assembly work.

Therefore, the main objective of the present invention is to support the design of parts that facilitate assembly work.

In order to solve the above problems, the design support apparatus of the present invention has the following features.
The present invention includes a parts input unit that receives input of assembly design data indicating an assembly;
Single parts constituting an assembly are extracted from the input assembly design data, and a plurality of single parts satisfying the fastening rule that adjacent screw holes exist in the same position of the single parts are combined into one single part. a parts integration section that groups together as integrated parts;
The present invention is characterized by comprising a display control unit that causes a display device to display manufacturing design data including the integrated component.
Other means will be described later.

According to the present invention, it is possible to support the design of parts that facilitate assembly work.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an explanatory diagram showing an overview of design data created by the design support apparatus 1 of FIG. 2. As shown in FIG.
The assembly design data 101 is shape data indicating the state of an assembly in which individual parts (bodies) are assembled, as used in conventional assembly work. Here, assembly design data 101 composed of five single parts A1 to A5 is illustrated. Note that a link between single parts indicates that two single parts can be connected to each other. Fastening refers to connecting parts together using screws, welding, etc. The unitary part A2 can be connected to the unitary parts A1 and A3, respectively, and the unitary part A4 can be connected to the unitary part A5.

As the design data 102, the design support device 1 groups a set of connectable single parts into one integrated part (subassembly). For example, the integrated component B1 is a group of fastenable single parts A1 to A3, and the integrated component B2 is a group of fastenable single parts A4 and A5.
Then, the design support device 1 appropriately modifies the design data so that each integrated component can be manufactured (modeled) by satisfying the constraints during manufacturing. For example, the integrated component B1 has become too large in size and exceeds the constraint condition 102a. In FIG. 1, the constraint condition 102a is indicated by a broken rectangle, and the integrated component B1 protrudes outside the rectangle to indicate that the constraint condition is not satisfied. On the other hand, the integrated component B2 satisfies the constraint condition 102b due to its appropriate size.

Manufacturing design data 111 shows the design data 102 after modification. Since the integrated part B1 cannot be manufactured as it is, it can be manufactured by canceling the grouping and returning to the original single parts A1 to A3.
In this way, the design support device 1 creates the manufacturing design data 111 by grouping each single component of the assembly design data 101 into an integrated component and making the integrated component manufacturable.
As a result, while the assembly design data 101 requires fastening work at three locations for five parts, the manufacturing design data 111 only requires fastening work at two locations for four parts. We were able to reduce the burden of assembly work.

FIG. 2 is a configuration diagram of the design support device 1.
The design support device 1 is configured as a computer having a CPU (Central Processing Unit), a memory, a storage means (storage unit) such as a hard disk, and a network interface.
In this computer, the CPU operates a control unit (control means) constituted by each processing unit by executing a program (also called an application or an application for short) read into the memory.
The design support device 1 includes a component shape input section (component input section) 11, a manufacturing device input section 12, a constraint input section 13, a fastening information DB 21, a component integration section 22, and a manufacturing constraint processing section 23. , a display control section 24, and an input/output section 30.

The component shape input unit 11 receives CAD (Computer Aided Design) data of an assembly as assembly design data 101 . Here, the CAD data may include explanatory information (tag information) such as material data in addition to shape data regarding one or more single parts. This explanatory information may be extracted from data other than CAD data, and the other data is, for example, BOM (Bills of Materials) data, which is a bill of materials used in the manufacturing industry.

The manufacturing equipment input unit 12 receives input of information (equipment ID, specification value, etc.) on the manufacturing equipment used to manufacture the integrated component.
The manufacturing device here is, for example, an additive manufacturing device such as a three-dimensional printer. A three-dimensional printer uses CAD data of a modeled product to produce a prototype or product in a short time through additive manufacturing (additive manufacturing, additive manufacturing, modeling).
Three-dimensional printers are used in a wide range of applications, not only for manufacturing prototypes for shape confirmation at the design stage, but also for precision products in the aviation and medical fields. Three-dimensional printers have a high degree of manufacturing freedom and can produce complex shapes that were previously difficult to manufacture.

The constraint input unit 13 receives input of constraints (such as the constraint 102a in FIG. 1) regarding the manufacturing apparatus specified by the manufacturing apparatus input unit 12. The constraint conditions define the manufacturing quality (manufacturing quality) that can be manufactured (allowed) by the manufacturing equipment. Constraints include, for example, each parameter that indicates manufacturing quality (dimensional tolerance, surface roughness, density of the modeled product, material structure (phase state, crystal structure, etc.), material uniformity, residual stress/strain, strength (hardness, The permissible ranges of thermal conductivity, thermal conductivity, specific heat, and thermal contraction) are defined using numerical ranges and geometric rules.
Thereby, by determining whether or not the constraint conditions are satisfied, it is possible to determine whether or not the integrated part can be manufactured before actually manufacturing it, even if the material properties change depending on the temperature history.

The component integration unit 22 refers to the fastening information DB 21 and groups a plurality of single components into one integrated component. For this reason, rules that allow a plurality of single parts to be fastened are registered in advance in the fastening information DB 21 (see FIG. 3 for details). For example, in FIG. 1, the single parts A1 and A2 are connected by a link by satisfying the rule that the single parts A1 and A2 are "welded joints."

The manufacturing constraint processing section 23 determines whether or not each integrated component created by the component integration section 22 satisfies the constraint conditions input from the constraint condition input section 13 . Here, rather than determining the constraint conditions for each individual part in the assembly design data as is, by grouping them into each integrated part and then determining the constraint conditions, the burden of determination processing can be reduced by reducing the number of parts. It can be reduced.

Then, the manufacturing constraint processing unit 23 creates manufacturing design data by executing one of the methods (corresponding examples) exemplified below for the integrated component that does not satisfy the constraint conditions.
(Correspondence example 1) A method of making it possible to manufacture by ungrouping integrated parts that do not satisfy the constraint conditions and returning them to the original single parts (schematic diagram in FIG. 1).
(Correspondence example 2) A method of making it possible to manufacture an integrated part that does not satisfy the constraint by dividing it into multiple parts (schematic diagram in FIG. 7).
(Corresponding example 3) A method of making the integrated part possible to manufacture by searching for a manufacturing device that has the constraint conditions that can manufacture the integrated part without changing the design data of the integrated part (as shown in the schematic diagram of FIG. 12).

The display control unit 24 controls the display device (monitor) to display manufacturing design data created from the assembly design data.
The input/output unit 30 is an input/output device that exchanges data between the user and the design support device 1, and inputs data to each input unit (part shape input unit 11, manufacturing equipment input unit 12, constraint condition input unit 13). It is configured as an input device for inputting information, and a display device that receives and displays a display screen signal from the display control unit 24.
The input/output unit 30 may be built in the design support device 1, such as a touch panel installed in the design support device 1 of a tablet terminal, for example. Alternatively, the input/output unit 30 may be configured as an operation terminal connected to the design support device 1 via a network.

FIG. 3 is a configuration diagram of the fastening information DB 21.
The fastening information DB 21 stores, for each rule name, an identification means indicating the type of assembly design data, and a parameter rule written in the identification means, as a rule that allows a plurality of single parts to be fastened into an integrated part. Match.
For example, the rule for "welding joint" in the first line states that the user determines that it can be joined based on the specified information that "welds" explicitly in the assembly design data. There is. This designation information may include a welding symbol read from a design drawing by image recognition, or a welding attribute read from CAD data by attribute recognition. This makes it possible to deal with cases where the CAD data does not include all the information for determining whether or not to conclude the contract.

In addition, in the "screw fastening" rule in the second line, although there is no explicit specification information to "perform screw fastening", there is a screw hole adjacent to the same position between two parts as a clue to suggest screw fastening. It is stated that it is determined that the conclusion is possible based on the existence of the In addition, even if there is a slight positional deviation due to the allowable error of 0.1 mm between the centers of the screw holes between two parts, they are considered to be in the same position.

FIG. 4 is a flowchart showing the processing of the component integration unit 22.
The component integration section 22 extracts single components from the assembly design data input by the component shape input section 11, and assigns a component ID as an attribute to each single component (S101).
Then, the component integration unit 22 executes a loop (S102 to S107) in which unprocessed component IDs are sequentially selected as parts of interest, and when there are no unprocessed component IDs (S102, No), the process ends.

The component integration unit 22 extracts other single components (other components) that are connected to the currently focused component (positions are close to each other) from the assembly design data (S103). Then, the component integration unit 22 refers to the fastening information DB 21 and determines whether the extracted other parts and the target component can be fastened together (S104). If the connection is not possible (S104, No), the component integration unit 22 adds the target component to the manufacturing design data without integrating it (S107).

On the other hand, if the connection is possible (S104, Yes), the component integration unit 22 groups the target component and other components as an integrated component (S105). For example, in the case of the assembly design data 101 shown in FIG. The parts are grouped as one integrated part B1. Then, the component integration unit 22 adds the integrated component of S105 to the list of integrated components (S106).
After the process of S106 or S107 is performed on the currently focused part, the component integration unit 22 regards the currently focused part as already processed and processes the next unprocessed part ID as a new focused part in S102. return.

FIG. 5 is a flowchart showing the processing of the manufacturing constraint processing section 23.
The manufacturing constraint processing unit 23 reads N integrated parts from the list of integrated parts created in S106 of FIG. A loop for sequentially selecting parts is executed (S211 to S216). Therefore, the manufacturing constraint processing unit 23 assigns a variable G=1 to focus on the first integrated component G (S202).

The manufacturing constraint processing unit 23 evaluates the quality (manufacturing quality) when the design data of the integrated part G is virtually manufactured based on the manufacturing equipment information input by the manufacturing equipment input unit 12 (S211). The integrated part G is not a real thing at this point, but is virtual design data.
Manufacturing quality is each parameter (dimensional tolerance, surface roughness, etc. as described above) that is evaluated under constraint conditions. In other words, manufacturing quality is quality data regarding the manufactured product of the integrated component G, assuming that the design data of the integrated component G is manufactured by a designated manufacturing device.
The manufacturing constraint processing unit 23 determines whether the manufacturing quality of the integrated component G evaluated in S211 satisfies the constraint condition input by the constraint condition input unit 13. For example, in FIG. 1, a case has been described in which the integrated component B1 does not satisfy the constraint condition 102a. If Yes in S212, the process advances to S213, and if No, the process advances to S214.

The manufacturing constraint processing unit 23 adds (adopts) the integrated part G determined to be manufacturable to the manufacturing design data (S213). On the other hand, the manufacturing constraint processing unit 23 ungroups the integrated parts G determined to be unmanufacturable into individual parts, and adds each of the individual parts to the manufacturing design data (S214). Then, since the manufacturing constraint processing unit 23 has finished processing the current integrated component G, it sets the next integrated component G+1 as a new integrated component G (S215).
Here, if G>N, and the processing of all integrated parts read in S201 is completed (S216, Yes), the manufacturing design data ( In the case of FIG. 1, the display screen of the manufacturing design data 111) is displayed on the display device from the display control unit 24 (S221).
On the other hand, if G≦N and unprocessed integrated parts remain (S216, No), the manufacturing restriction processing unit 23 returns the process to S211.

FIG. 6 is a display screen diagram of the display control unit 24. As shown in FIG.
The display screen includes a display field 500a for assembly design data, a display field 500b for manufacturing design data, an approval button 591, and a disapproval button 592.
In the display column 500a, an assembly in which the individual parts 501, 502, and 503 are assembled by the respective fastening parts (welding parts 511, 512, and screws 513) is displayed as shape data. Welding portion 511 connects unitary parts 501 and 502. Welding portion 512 connects unitary parts 502 and 503. A screw 513 connects the single parts 501 and 503.

In the display field 500b, the single component 501 in the display field 500a remains as is, and the single components 502 and 503 are grouped into one integrated component 504.
First, the component integration unit 22 makes each single component 501, 502, 503 into one integrated component by making each fastening part (welded parts 511, 512, screw 513) satisfy the rules of the fastening information DB 21 ( (not shown).

Here, the three-dimensional printer manufactures an integrated part by stacking members in a stacking direction from the bottom to the top in FIG. Therefore, the manufacturing constraint processing unit 23 processes each of the three individual parts according to the stacking condition "If the stacking height of the parts is too high, the parts become unstable" as a constraint condition of the three-dimensional printer that manufactures the integrated parts. If 501, 502, and 503 are made into one integrated part, it is determined that the height restriction is exceeded.
Therefore, the manufacturing constraint processing unit 23 excluded only the single component 501 from the grouping and made the remaining single components 502 and 503 into one integrated component 504 to satisfy the constraint conditions.
Indices of the angle (overhang angle) of the lower surface of the protruding portion called an overhang, length, area, and volume may be set as the lamination conditions. Further, in the lamination conditions, an index of the length of a side in a specific direction may be set, or an index of an aspect ratio, which is the ratio of the lengths in two directions, may be set. Furthermore, the lamination conditions may be set by combining these.

By comparing the display field 500a and the display field 500b before and after integration, the user can confirm that the assembly work has been reduced by one location (welding portion 512).
Then, the user's approval or disapproval of this integration plan is input using the approval button 591 or the disapproval button 592. This eliminates the need for the user to create a component integration plan by himself. Therefore, the user only needs to input the acceptance or rejection of the integration plan automatically created by the design support device 1, which can save labor in the integration study work.

Above, the manufacturing constraint processing unit 23 (correspondence example 1: method for canceling grouping) has been described with reference to FIGS. 1 to 6. Hereinafter, with reference to FIGS. 7 to 9, a description will be given of (correspondence example 2: method of dividing an integrated part) of the manufacturing constraint processing unit 23.
FIG. 7 is an explanatory diagram showing an overview of dividing the design data according to (correspondence example 2).
Although the component integration unit 22 creates the design data 102 from the assembly design data 101, the process up to the point where the integrated component B1 exceeds the constraint condition 102a is as explained in FIG. 1.

Therefore, the manufacturing constraint processing unit 23 considers the integrated component B1 to be one component with a large particle size, and divides the integrated component B1 into a divided component B11 and a divided component B12 that are fastened to each other. As a result, the divided part B11 satisfies the constraint condition 102a, the divided part B12 satisfies the constraint condition 102c, and the integrated part B2 satisfies the constraint condition 102b. Therefore, the manufacturing constraint processing unit 23 can create the manufacturing design data 112 that allows manufacturing of all parts.
As a result, although the assembly design data 101 requires fastening work at three locations, the manufacturing design data 112 only requires fastening work at one location between the divided parts B11 and B12, and the assembly I was able to reduce the workload.

FIG. 8 is a flowchart showing the processing of the manufacturing constraint processing unit 23 in (correspondence example 2).
The difference between FIG. 8 and FIG. 5 is that the process (S214) of ungrouping the integrated part G determined to be unmanufacturable in FIG. This is replaced by the process of dividing G (S214B) and returning to S211. Then, in the second quality evaluation process (S211), the manufacturing constraint processing unit 23 performs quality evaluation of the divided parts instead of the integrated part G.

FIG. 9 is a display screen diagram of the display control unit 24 in (correspondence example 2).
The display screen includes a display field 500c for design data before division, which is the same design data as display field 500b in FIG. 6, a display field 500d for manufacturing design data after division, an approval button 591, and a disapproval button 592. and is included.
It is assumed that the manufacturing constraint processing unit 23 determines that the integrated component 504 does not satisfy the constraint condition 521 in the display column 500c.

Therefore, as shown in the display field 500d, the manufacturing constraint processing unit 23 divides the integrated part 504 into a divided part 505 and a divided part 506, and newly connects both parts with a welded part 514. As a result, the divided component 505 satisfies the constraint condition 521, and the divided component 506 satisfies the constraint condition 522.
By comparing the display field 500c and the display field 500d before and after division, the user can confirm that manufacturing design data that satisfies the constraint conditions has been created by component division.

FIG. 10 is a configuration diagram showing a modification of the design support device 1. As shown in FIG. This design support device 1 has the following elements changed from among the components of the design support device 1 shown in FIG.
As a first change, the component shape input section 11 in FIG. 2 is replaced with the component search section 11a and component information DB 11b in FIG. Candidates for CAD data and BOM data are registered in the parts information DB 11b as the assembly design data described in the part shape input section 11 of FIG. When the component search unit 11a receives a search condition for assembly design data such as the name of CAD data from the input/output unit 30, it searches for the corresponding assembly design data from the component information DB 11b. The retrieved assembly design data is input to the component integration section 22 in the same manner as in FIG.

FIG. 11 is a configuration diagram of the manufacturing apparatus DB 12b.
As a second change, the manufacturing equipment input unit 12 in FIG. 2 is replaced with the equipment search unit 12a and manufacturing equipment DB 12b in FIG. 10. Candidates for manufacturing equipment used to manufacture integrated parts are registered in the manufacturing equipment DB 12b. The manufacturing equipment DB 12b stores correspondence information among equipment names, equipment IDs, constraints, and operating information for each manufacturing equipment candidate.
When the device search unit 12a receives a search condition for a manufacturing device from the input/output unit 30, it searches for information on one or more corresponding manufacturing devices from the manufacturing device DB 12b. For example, the device search unit 12a searches for two candidates with the search result “device ID=3D-A1, 3D-A2” using the search key “development printer”. Alternatively, the device search unit 12a may use a search condition such as "all devices registered in the database" without specifying the name of the manufacturing device.

The manufacturing equipment information retrieved from the manufacturing equipment DB 12b is a combination of the input data (equipment ID, etc.) of the manufacturing equipment input unit 12 in FIG. 2 and the input data (constraint conditions) of the constraint condition input unit 13 in FIG. Instead, it is input to the manufacturing constraint processing section 23.
Note that the device search unit 12a may include information on the time of use as a search key when searching for manufacturing device candidates. For example, the device search unit 12a obtains the search result "device ID=3D-A2" based on the search key "development printer available in December." On the other hand, "Device ID = 3D-A1" matches the search condition of "Printer for development", but the operation information contains other reservations (manufacturing of product X2) in December, so the search results do not match the search condition. Excluded.

FIG. 12 is an explanatory diagram illustrating an outline of a search for a manufacturing apparatus that can manufacture integrated parts as they are according to (correspondence example 3).
Although the component integration unit 22 creates the design data 102 from the assembly design data 101, the process up to the point where the integrated component B1 exceeds the constraint condition 102a is as explained in FIG. 1.

Therefore, the manufacturing constraint processing unit 23 uses a second manufacturing device that has the constraint condition 102d instead of the first manufacturing device that has the constraint condition 102a (for example, the 3D-A1 printer that can only manufacture small parts in FIG. 11). (For example, the 3D-A2 printer shown in Fig. 1, which can also manufacture medium-sized parts) is adopted. As a result, a margin is created in the constraint condition 102d, and the integrated component B1 can be manufactured as is.
As a result, although the assembly design data 101 requires fastening work at three locations, the manufacturing design data 113 does not require fastening work, and the burden of assembly work can be greatly reduced.

FIG. 13 is a flowchart showing the processing of the manufacturing constraint processing unit 23 in (correspondence example 3).
The difference between FIG. 13 and FIG. 5 is that the processing in S212 to S214 in FIG. 5 is replaced with the following processing in FIG.
The manufacturing constraint processing unit 23 searches for a manufacturing device that satisfies the manufacturing quality with the constraint condition by performing a manufacturing feasibility determination based on the constraint condition (S212 in FIG. 5) for each manufacturing device candidate read from the manufacturing device DB 12b. (S212C in FIG. 13). Note that when a plurality of manufacturing apparatuses capable of manufacturing the integrated component G are found in S212C, it is desirable to employ the most suitable manufacturing apparatus among them. An optimal manufacturing device is, for example, a manufacturing device with the lowest usage cost or a manufacturing device with the shortest waiting time until use.
In addition to the integrated parts G that can be manufactured in FIG. 13 (S213 in FIG. 5), the manufacturing constraint processing unit 23 also includes information on the manufacturing equipment (such as equipment ID) searched in S212C to manufacture the integrated parts G. It is associated and added to the manufacturing design data (S213C in FIG. 13).

FIG. 14 is a display screen diagram of the display control unit 24 in (correspondence example 3).
The display screen includes the same assembly design data display field 500a as in FIG. 6, a display field 500e for integrated parts integrated with the component integration section 22, an approval button 591, and a disapproval button 592. .
In the display field 500e, the integrated component 509 is displayed as is without being ungrouped or divided into components due to the constraint conditions. Furthermore, since information 509p of manufacturing equipment capable of manufacturing the integrated component 509 is also associated in the manufacturing design data, it can be displayed together with the display field 500e.
By comparing the display field 500a and the display field 500e before and after integration, the user can confirm that the three fastening parts (welded parts 511, 512, screws 513) have been reduced.

In the present embodiment described above, the component integration unit 22 of the design support device 1 uses design data in which small single parts included in the assembly design data are grouped into large integrated parts based on the rules of the fastening information DB 21. Create. The manufacturing constraint processing unit 23 then determines whether the integrated component can actually be manufactured. Here, by dealing with integrated parts that cannot be manufactured using the methods described in (Example 1) to (Example 3), the manufacturing constraint processing unit 23 Create design data.

This makes it possible to assemble the same assembly using assembly design data containing only single parts and manufacturing design data including integrated parts. Therefore, by replacing single parts with integrated parts, the following effects can be obtained.
- The effect of reducing the number of parts is that packaging of parts can be simplified, reducing storage costs, transportation costs, and disposal costs.
・The effects of reducing the number of fastening parts include reducing the burden of fastening work and suppressing deterioration in the quality of assembled products due to unfamiliar fastening work.
