Description

  The present invention relates to an assemblability evaluation system that artificially evaluates the assemblability of a product, and more particularly to an assemblability evaluation system having a function of reducing the complexity of data input for evaluation.

  Conventionally, CAD data of an assembly, which is a product for which design has been completed, is sent from the design department to the production engineering department. The production engineering department creates an assembly process based on the CAD data, and evaluates this assembly process. The manufacturing process was reviewed from the evaluation results. In this process, naturally, a computer is used to extract each part data from CAD data including the part data, and the user manually inputs an assembly process appropriately using an input device. The user needs to input not only the order of the parts to be used, but also the tools used in the assembly process and operations for the target parts. After inputting these pieces of information, by executing the evaluation, values are substituted into variables of the evaluation formula formulated in advance, and various evaluation values are output. Then, the user improves the assembly process by changing the tool to be used, changing the order of the parts, or changing the operation on the target part so that the evaluation value becomes a certain value or more with respect to the portion having a bad evaluation value.

  As background art, Japanese Unexamined Patent Application Publication No. 2002-144171 discloses a quantitative evaluation system for assembly and an automatic simulation system. In this system, focusing on the problem that it takes a lot of time to create evaluation data for evaluation by the user himself, which leads to an increase in labor costs, automatic evaluation data is automatically created as much as possible based on CAD data. It is proposed to create it.

  Specifically, it includes a three-dimensional CAD data storage unit, a member extraction unit, a detailed data storage unit, an evaluation data creation unit, an evaluation data storage unit, and an assembly evaluation unit. The three-dimensional CAD data storage unit stores the CAD data as attribute data for specifying each member constituting the product. The member extraction unit automatically disassembles each member of the product based on the data in the three-dimensional CAD data storage unit, and extracts the member data of each member. The member data is data relating to a member name, a member position, a movement vector, an attachment order (indicating a parent-child relationship of members), a member attribute (type = equal to assembly contents), or the like. This member data is stored in the detailed data storage unit. The evaluation data creation unit automatically creates evaluation data that can be a parameter for evaluating workability from each member data in the detail data storage unit. The evaluation data is stored in the evaluation data storage unit. The assembly evaluation unit performs quantitative evaluation of the assembly work by assigning a predetermined score to the stored evaluation data and performing predetermined processing.

Furthermore, when performing simulation, the movement of each member is created as motion data using the motion element simulation database based on data such as how to remove, attach, and attach each member in the data in the detailed data storage unit. . Then, using this motion data, a three-dimensional simulator is used to simulate on a display monitor to allow visual assembly evaluation.
JP 2002-144171 A

  However, the quantitative evaluation system and the automatic simulation system of the assembly technology of the background art create detailed data from 3D CAD data and attributes and evaluate them, and create operation data from the detailed data. Originally, 3D CAD data or attributes are created. However, there is a problem that the contents of the evaluation data and the operation data necessary for the evaluation and simulation are required, or the user has to input as needed.

  The present invention has been made in order to solve the above-mentioned problems, and not only extracts data used for evaluation from three-dimensional CAD data but also functions used in other processes, subsequent processes, or auxiliary processes. It is an object of the present invention to provide an assemblability evaluation system that can easily input for evaluation by inputting for realization and can actually use the function.

  In the present invention, data of each part is acquired from the three-dimensional CAD data, an assembly process is created using the acquired part data while receiving the user's operation, and how each part is operated and how Information on how to use various tools is input by the user's operation using a graphical user interface, and not only animation is output by the input information, but also that information and assembly process information It is used to evaluate assembly. By doing so, it is possible to actually check the assembly process by animation without inputting data only for evaluation by the user, and to evaluate the assemblability based on the information obtained by animation. it can. In addition, it is possible to create an assembly process without omission in order to perform input for creating an animation. Furthermore, animation can be used as a demonstration of actual operation instructions at the manufacturing site.

(1) An assembly property evaluation method according to the present invention is an assembly property evaluation method for evaluating the assembly property of an evaluation object using a computer having a processor and a storage means, wherein the processor includes components as components. a step of capturing a three-dimensional CAD data which is design information, the processor retrieves the parts from three-dimensional CAD data fetched, and creating the assembly process by arranging the removed parts, the processor accepts a change to the assembly process Change the order of the assembly process, create assembly process data containing the assembly process , and accept operations for the part for creating an animation until the processor assembles the assembly from the part. a step to create a operation data indicating the operation content, the assembling property recorded in the storage means Using the conditions for evaluation , the processor creates evaluation data based on the three-dimensional CAD data, assembly process data, and operation data , and substitutes the evaluation data created by the processor into the evaluation formula recorded in the storage means Thus, the step of obtaining the evaluation result and the step of outputting the evaluation result obtained by the processor are included.

As described above, according to the present invention, the 3D CAD data is taken in, the parts constituting the assembly are read from the 3D CAD data, the parts are arranged, the editing to the assembly process is accepted, the assembly process data is created, and the animation is generated. The operation from the user to create is received, the operation data indicating the operation contents for the parts by the received operation is generated , and the evaluation data is generated by using the evaluation rule from the three-dimensional CAD data, the assembly process data and the operation data. Since the created evaluation data is substituted into an evaluation formula prepared in advance and the evaluation result is obtained, the input required by the user is the part for creating the assembly process editing and assembly animation. After that, evaluation data is automatically created and evaluation results can be obtained, greatly reducing the user input. An effect that can be improved.
In addition, according to the present invention, the user can create an animation after reading the parts constituting the assembly from the three-dimensional CAD data, arranging the parts and accepting the edit to the assembly process, and setting the actual assembly process. Therefore, the user can easily create an animation, and as a result, the evaluation result can be acquired quickly. In addition, assembling an assembly is basically a series of operations to attach a part that constitutes the assembly to another part, so that the part is read from the 3D CAD data and presented as an assembly process for the time being. This will sufficiently assist the user in creating the assembly process.

  Even if it is necessary to input only to create evaluation data in addition to the input for creating animation, there is a part where the evaluation result can be automatically obtained by creating animation, and at least that part is used. This saves the user input. In addition, since the user creates the animation process, it is possible to prevent the processing required in the process of assembling the assembly from the parts from being lost, and this also serves to prevent the evaluation of the assembly performance from being lost.

  The animation created by the user is output to an output device such as a display in the creation process and can be browsed by the user. In particular, the animation created by the user is determined by the operation of the part for which the evaluation data is created. When the evaluation result is worse than the threshold value, the evaluation result can be revealed and drawn by drawing the animation after the evaluation. By doing so, it is possible to make a horn for the user for an operation that needs to be reviewed in particular. For example, the drawing speed of the corresponding frame can be slowed down or stopped, or the color scheme of all or part of the image area of the playback image can be changed.

Here, the operation on the part includes an operation of a tool used on the part. The movement of the part includes the movement of the tool.
The operation of the component is operation data, and includes, for example, a character string in a command format and a character string in a script format. However, since at least the operation data may be processed internally, it may be an assembly code or object code that is difficult for humans to identify.

( 3) The present invention can also be grasped as a system or an apparatus.
(4) The present invention can also be understood as a program.
These outlines of the invention do not enumerate the features essential to the present invention, and a sub-combination of these features can also be an invention.

Here, the present invention can be implemented in many different forms. Therefore, it should not be interpreted only by the description of the following embodiment. Also, the same reference numerals are given to the same elements throughout the embodiment.
In the embodiment, the system will be mainly described. However, as is apparent to those skilled in the art, the present invention can also be implemented as a program and a method usable on a computer. In addition, the present invention can be implemented in hardware, software, or software and hardware embodiments. The program can be recorded on any computer-readable medium such as a hard disk, CD-ROM, DVD-ROM, optical storage device, or magnetic storage device. Furthermore, the program can be recorded on another computer via a network.

(First embodiment of the present invention)
(1) Configuration FIG. 1 is a system configuration diagram of an assemblability evaluation system and related systems according to the present embodiment.
Designers in the design department design with a CAD system based on design specifications. 3D CAD data, which is a product of the design department, is received by a production engineer in the production engineering department via the network, and an assembly process of the 3D CAD data is created and evaluated using an assembly evaluation system. Create animations. When the inspection in the production engineering department is completed, the production in the production department is started. In this manufacturing department, in general, manufacturing instructions are sent from the production engineering department, and products are produced based on this, but the animation that is the product of the assembly evaluation system is sent to the manufacturing department via the network. Then, the transmitted animation can be received and drawn by a tablet PC with a wireless communication function of the manufacturing department, and can be manufactured efficiently and without error while watching the animation. Of course, the production engineer can additionally give comments such as technical points to the animation created by the assemblability evaluation system.

Hereinafter, the assemblability evaluation system will be described.
FIG. 2 is a detailed block diagram of the assemblability evaluation system according to this embodiment.
The assemblability evaluation system according to this embodiment includes an input unit 11, a data extraction unit 21, an assembly process setting unit 31, an animation setting unit 41, an evaluation data creation unit 51, an evaluation calculation unit 52, and an output unit 61.
The input unit 11 has a function of taking data into the system. For example, three-dimensional CAD data is taken into the system from the CAD system via the network.
The data extraction unit 21 has a function of sequentially extracting parts constituting the assembly from the three-dimensional CAD data. The sequential extraction means that the three-dimensional CAD data is extracted in the order of the storage position, the order of identification information for identifying the components, or the like.

  The assembly process setting means 31 presents the parts extracted by the data extraction means 21 from the three-dimensional CAD data to the user as an assembly process as they are, and changes the order of the assembly processes in response to the user's operation. It has a function. At this time, the assembly process setting means 31 handles assembly process data including the combination process. Although the assembly process setting means 31 presents the extracted parts to the user as an assembly process in the same arrangement, the extracted parts may be rearranged. The rearrangement may be in the order of identification information for identifying components, in the order of component creation date and time, in order of component data size, or the like. Further, when the assembly process order is included in the three-dimensional CAD data, the order can be rearranged in the known range and presented to the user. At this time, the extraction order of the data extraction means 21 may be the order of the assembly process included in the three-dimensional CAD data.

  The animation setting means 41 has a function of generating operation data indicating how to operate equipment such as a certain part or tool in response to an instruction from the user. The operation data consists of operation commands. The operation on the component (including the component) is, for example, movement or rotation of the component. The movement and rotation of the parts are basic operations on the parts, but more complicated operations can be collectively performed. Specifically, when the other component is screwed to one component, the other component moves in the vertical direction while rotating, but this operation may be collectively screwed.

  The evaluation data creation means 51 creates evaluation data, which is data for performing an evaluation calculation, from CAD data, assembly process data, and operation data. Here, in the present invention, evaluation data is created not only from CAD data, but also from assembly process data and operation data, so that the data that the user needs to input and select substantially is further reduced. Can be omitted significantly. The evaluation data creating means 51 creates evaluation data by judging whether or not a certain operation corresponds to a condition (evaluation rule) that affects the evaluation of assemblability. For example, if there is a part reversal, it is difficult for an operator to assemble compared to a part without a part reversal, and the assemblability deteriorates. Therefore, the reversal is one of the conditions for evaluating the assemblage. Conditions other than reversal include part dimensions, part weight, attention to grip, assembly target dimensions, clearance, assembly direction, assembly operation, cable (open), cable (closed circuit), coupling, tool use, There are fastening part direction, product reversal, additional work, FPC bending work, etc. The conditions shown here are only examples and depend on the type of assembly to be manufactured.

  In the present embodiment, a command is generated by creating an animation with the animation setting means 41, and the evaluation data creation means 51 analyzes the command and assembles the assembly direction, presence / absence of component reversal, tool use, fastening direction, and the like. Automatically collect data related to gender. Further, the evaluation data creating means 51 executes assembly animation, and automatically detects a process with less dynamic interference information and less clearance during assembly. Dynamic interference is that parts are in contact with each other by mistake and cannot be assembled accurately. For example, when a certain part A is assembled to part B, part C is already attached in a protruding shape to part B. When the part A is assembled to the part B with the shortest path as it is, the case of contacting the part C is applicable. In such a case, it is possible to bypass the component A and assemble it at a predetermined position of the component B, or assemble the component A before assembling the component C to the component B, thereby avoiding contact and enabling correct assembly.

  Conventionally, a list table related to assemblability consisting of conditions for evaluating multiple assemblages is mounted on the form in the form of check boxes and list boxes for each process. Since the user selects the condition corresponding to the process from among the processes and the evaluation is performed after the input is completed for all the processes, not only the user's input burden is large, but there are many input errors. On the other hand, if the assemblability evaluation system of this embodiment is used, the user only creates an animation necessary for the assembling process, and the evaluation data creating means 51 automatically performs the assembling process based on the operation data of the animation. Since it is determined whether or not various conditions relating to evaluation are satisfied and evaluation data is created, it is possible to avoid trouble of input and input mistakes. Here, when an infinite number of assembly-related list tables are implemented for each process in the form of check boxes and list boxes, the corresponding check boxes and list boxes for each process are automatically selected. In addition to avoiding the trouble of input and input errors, the user can reconfirm the setting contents for assembling evaluation, and can also correct as appropriate. On the contrary, if the setting contents are wrong, there is a possibility that the animation itself may be wrong, which leads to improvement in the accuracy of the animation. Furthermore, when reconfirming the setting contents for assembly evaluation, if you select the setting contents that are currently set and specify drawing, you can also make a configuration where the animation of the corresponding setting contents part is drawn, It is easy for the user to grasp the setting contents. On the contrary, when an animation is drawn, the related setting content may be revealed.

  The evaluation calculation means 52 calculates the evaluation by substituting the evaluation data into a predetermined evaluation formula. As the evaluation expression, an expression prepared by the system by default can be used, and the coefficient, variable, and operator of the evaluation expression can be edited by the user. Of course, the user may create and set it from scratch. The calculated value is an evaluation result related to assemblability. For example, assembling evaluation point, parts assembly time, gripping time, assembly operation time, forming time, assembly holding time, coupling time, product inversion time, additional time, incidental Time, gripping, self-holding, assembly operation, forming, connection, product reversal, man-hour evaluation, component configuration evaluation, gripping evaluation, self-holding evaluation, assembly operation evaluation, cable evaluation, connection evaluation, product There are reversal evaluation, fastening use evaluation, fastening type evaluation, and the like. Of course, the evaluation result obtained using the evaluation formula may be the value of the variable of the evaluation formula. When evaluating time, it is possible to specify accuracy by specifying the moving speed, rotational speed, and fastening speed even when creating animation, but it may be configured to be set together with the work time of each process .

  The output unit 61 has a function of sending data out of the system. The output unit 61 outputs the three-dimensional CAD data captured by the input unit 11 to the video card 119 and the display 119a, whereby a three-dimensional image is displayed on the display 119a (three-dimensional CAD display function). When the assembly process setting means 31 presents the assembly process to the user, the output means 61 outputs the assembly process to the video card 119 and the display 119a, whereby the assembly process is displayed on the display 119a (assembly process display). function). The output result 61 is also output to the video card 119 and the display 119a by the output means 61, and the evaluation result is displayed on the display 119a (evaluation result display function). In this embodiment, the output unit 61 has a three-dimensional CAD display function, an assembly process display function, and an evaluation result display function. However, the output unit 61 is newly provided with a three-dimensional CAD display unit, an assembly process display unit, and an evaluation result display unit. The configuration may be such that each function is assigned to each.

(2) Hardware Configuration FIG. 3 is a hardware configuration diagram of a computer in which the assemblyability evaluation system according to the present embodiment is constructed.
The computer 100 in which the assemblability evaluation system is constructed is a CPU (Central Processing Unit) 111, a RAM (Random Access Memory) 112, a ROM (Read Only Memory) 113, a flash memory (Flash memory) 114, and an external storage device. HD (Hard disk) 115, LAN (Local Area Network) card 116, mouse 117, keyboard 118, video card 119, display 119a which is a display device electrically connected to this video card 119, sound card 120, and this sound card A speaker 120a, which is a sound output device electrically connected to 120, and a drive 121 for reading and writing a storage medium such as a floppy disk, CD-ROM, and DVD-ROM.
Here, in this embodiment, the assemblability evaluation system is constructed by one computer, but it can of course be constructed by a plurality of computers.

(3) GUI
(3.1) Display FIG. 4 is an example of a main window of the assemblability evaluation system according to the present embodiment. The main window is composed of several areas. The three-dimensional drawing area for directly displaying the three-dimensional CAD data fetched by the input means 11 as it is and the parts extracted by the data extracting means 21 are related to each other. There is a part configuration display tree area shown in a tree structure. By operating the mouse 117, the user can change the viewpoint angle with respect to the display object in the three-dimensional drawing area, and can perform operations such as enlargement / reduction. In addition, although the parts that make up the assembly that is the display object can be selected with the pointer, the parts in the three-dimensional drawing area can be selected by selecting the parts shown in the part structure display tree area with the pointer. You can also

(3.2) Editing of Assembly Process FIG. 5 is an example of a subwindow for the assembly process of the assembly performance evaluation system according to this embodiment.
The sub-window has a plurality of fields, and the flow field therein illustrates the assembly process. In the flow field, an inverted triangle indicates a part, and a circle indicates one of the assembly processes. Therefore, the entire assembly process is indicated by each assembly process and parts used in the assembly process. At the stage of extracting parts from the three-dimensional CAD data by the data extraction means 21, the assembly process is basically not completed, and the user changes the order of the assembly process using the sub-window for the assembly process. In the method for changing the assembly process, the order of the assembly process is changed by dragging an assembly process that needs to be changed in a selected state and dropping it at an appropriate location.

(3.3) Creation of Animation Sean Animation is created by the user in the main window. The animation is realized by designating from the operation for the part or the equipment related to the first assembly process to the operation for the part or the equipment related to the last assembly process in a state where nothing is displayed in the three-dimensional drawing area. Here, in order to make it easier and more efficient for the user to create an animation, it is specified from the operation on the part or fixture related to the last assembly process for the assembly, or the parts related to the first assembly process sequentially. The operation up to the equipment is specified. When the operation data is stored in this way, the animation is drawn in the order of the normal assembly process by performing reverse reproduction. Further, it is not always necessary to sequentially operate from the first part to the assembly, and an animation can be created for each part. Specifically, since the assembly process has already been completed, an animation is created for each process.
Specifically, operations for parts or fixtures include movement, rotation, fastening, and crimping. Here, the movement and rotation will be specifically described as examples.

  FIG. 6 is an explanatory diagram of command generation by movement setting according to the present embodiment. The movement is set by selecting a part in the three-dimensional drawing area and moving the part to the target point while dragging. The animation setting means 41 receives this operation and generates a command. By selecting a part in the first step, a command “SELECT Parts A” is generated. At the start of dragging of the second stage component, it is detected that dragging has started, and the start position (fromPos) is stored. At the end of dragging of the third stage component, it is detected that the dragging has ended, the end position (toPos) is recorded, and a command “MOVE PartsA fromPos to toPos” is generated. By selecting other parts in the fourth stage, commands of “UNSELECT Parts A” and “SELECT Parts B” are generated. It is also possible to select a part to be operated, specify “move” by operation, and specify movement start coordinates and movement end coordinates to set movement. In addition, when the pointer is moved with the mouse, it can be moved with restriction. For example, when the pointer is moved in parallel with the XY coordinate plane, the pointer is moved in parallel with the XY coordinate plane. It is difficult to move the pointer, and in this case, the movement parallel to the XY coordinate plane can be easily set by applying a restriction that the pointer can be moved only in parallel to the XY coordinate plane.

Next, rotation will be described. FIG. 7 is an explanatory diagram of command generation by rotation setting according to the present embodiment. It can be set by selecting a part in the three-dimensional drawing area, specifying a rotation axis, and specifying a rotation direction and a rotation angle. By selecting a part in the first step, a command “SELECT Parts A” is generated. Information on the rotation axis is stored according to the instruction of the rotation axis in the second stage. Instructing the rotation direction and rotation angle in the third stage, and completing the drawing in the fourth stage, a command “ROTATE CLOCKWISE Parts A ROTATEAXIS Ax from Ang to to Ang” is generated. By selecting another part in the fifth stage, commands “UNSELECT Parts A” and “SELECT Parts B” are generated.
Tool command examples are “Move driver from pos TOP to PosY” and “Move spanner from posSide to PosZ”.

(4) Creation of evaluation data from operation data Information on evaluation is acquired from operation data. The fact that the operation is accompanied means that the work of the worker or the machine is accompanied at the manufacturing site, and it is necessary to acquire information necessary for the evaluation of the assembling property. Many evaluations can be performed based on information acquired in the process of actual assembly by animation. The following describes how evaluation data is created from operation data for three specific examples.

(4.1) Collection of parts assembly direction The fact that a part is moving means that the movement direction of this part can be grasped from its operation, and the assembling direction is determined by this grasping.
Recognizing that there is a command “MOVE PartsA fromPos to toPos” in the operation data, the assembly direction is grasped from the vector direction from “fromPos” to “toPos”. FIG. 8A shows the vertical assembly from top to bottom, and FIG.

Assembling in the horizontal direction from left to right in (2) affects the assemblability. Of course, the weight and size of “Parts A” that is the object of movement also affect the assemblability. The weight and size of such parts are often stored as attributes in the CAD data, and basically no user input is required for the acquisition.

(4.2) Collection of presence / absence of component reversal The fact that a component is reversed can be determined by whether or not the component has rotated more than a predetermined amount. Therefore, by determining whether or not the part has rotated more than a predetermined amount, it is possible to determine whether or not the part is reversed.
It is recognized that there is a command “ROTATE CLOCKWISE Parts A ROTATEAXIS Ax from Ang to to Ang” in the motion data. Determine if the direction is rotating. In the case of rotation in the left-right direction, component inversion does not occur. If it is determined that the rotation is in the vertical direction, an angle difference is obtained from “froAng” and “toAng”, and if this angle difference is within a predetermined range, it is determined that there is an inversion.

(4.3) Collecting Tool Use and Fastening Direction It is necessary to add movement and rotation operations to the tool to execute processing on the part, and commands are created in the same way. The difference between a part and a tool is that the command argument is a tool, not a part. Therefore, in order to create evaluation data related to a tool, a command taking the tool as an argument is found, detailed information on the target tool is obtained, and the operation of the tool by the command is grasped. FIG. 10 is a specific explanatory diagram of tool commands. First, it is determined whether or not it is a tool by referring to the part type in the part information from the part number related to the argument of the command. If it is determined to be a tool, secondly, detailed information of the tool is acquired. Thereby, it is possible to grasp what kind of work is to be performed. Third, for example, when it is necessary to obtain the fastening direction, it can be obtained from the remaining arguments of the command in the same manner as the case of obtaining the assembly direction of the parts.

(5) Process Flowchart FIG. 11 is an operation flowchart of the assemblability evaluation system according to this embodiment. With this operation flowchart, the user can easily and quickly evaluate assembly.
When the user designates the three-dimensional CAD data, the input unit 11 reads the three-dimensional CAD data (step 101).
The data extraction means 21 extracts the parts from the read three-dimensional CAD data, creates assembly process data in the extracted order, and the assembly process setting means 31 receives the user's operation as necessary to change the order of the processes. The assembly process data is changed by adding or deleting processes (step 201).

The animation setting unit 41 creates motion data in response to the user's operation (step 301). The animation setting unit 41 determines whether or not the creation of the animation has been completed. If it is determined that the animation has not been completed, the process returns to step 301. If it is determined that the process has been completed, evaluation data is automatically created based on the operation data created mainly by the evaluation data creation means 51, and the evaluation calculation means 52 calculates the evaluation of assemblability (step 401). .
The evaluation result calculated by the output means 61 is output to the output destination (step 402).

(6) Effect of this Embodiment As described above, according to the assemblability evaluation system according to this embodiment, the user can easily obtain the operation data using the parts obtained from the three-dimensional CAD data and the created assembly process data. The evaluation data for evaluating the assembly property is automatically created from this motion data, and the evaluation of the assembly property is executed with the input for creating the evaluation data of the user greatly omitted. it can. In addition, by specifying the three-dimensional CAD data, the assembly process can be completed simply by correcting the assembly process from the beginning without creating it by the user, which can greatly save the user. Furthermore, the created animation can be used as a manufacturing instruction for the manufacturing site. Furthermore, the assembly process itself is not lost by creating an animation. In other words, if you draw an animation, you can immediately notice the missing process.
