Description

3D design data synchronization device and method

[0001] The present invention relates to a 3D design data synchronization device and method.

[0002] 3D design data created during the product development phase is used for process planning and work instructions during the production process. However, 3D design data can frequently change or be reconfigured during subsequent development or production of the product. However, most workplaces have separate product development and production departments, making it difficult to verify data between them. This limits the utility of 3D design data.

[0003] In particular, work instructions are usually managed by production managers manually writing product information one by one in the form of worksheets such as Excel using actual product photos or 2D drawings.

[0004] Since there is a high possibility of human error and missing parts due to manual writing by the person in charge, the work instructions may have a low level of completion, and when 3D design data changes, it is difficult to clearly confirm the changes, so the hassle of having to check and manually write each change increases work fatigue and reduces work efficiency.

[0005] In addition, if there is a discrepancy between the 3D design data at the design stage and the 3D design data at the production stage, it is difficult for the production manager to confirm whether the work instructions currently in use are based on the latest design data, and even if the production manager recognizes that there is a change in the 3D design data, it is difficult to confirm which design data is the latest design data.

[0006] For power products, handling safety according to electrical characteristics is important during the product production stage, and changes in 3D design data must be updated accurately and quickly to ensure the safety of those in charge.

[0007] Meanwhile, as mentioned above, when work instructions are created based on actual product photos, there is a problem of reduced work efficiency due to the lack of intuitiveness, making it difficult for production managers to utilize the work instructions in product production.

[0008] Therefore, there is a need to develop ways to improve productivity, such as reducing production time, by providing more intuitive and visible work instructions.

[0009] The purpose of the present invention is to provide a 3D design data synchronization device and method that prevents human error and enables efficient product production through unified product information management from the product development stage to the production stage.

[0010] An object of the present invention is to provide a 3D design data synchronization device and method that provide intuitive and high-quality 3D work instructions and augmented reality work instructions.

[0012] The processor may generate a bill of process (BOP) including the production material specification and process plan information for the product, and may link the BOP to the design material specification, the production material specification, and the 3D work instructions so that the 3D design data of the process specification is also synchronized.

For example, the user input may be a user input for reconstructing a design material specification to create a production material specification, a user input for creating a 3D work instruction manual, etc. In addition, if it is a user input required to link information generated throughout the entire process from the product design stage to the production stage, it may be applied without limitation.

[0071] The input unit (110) includes at least one input means. The input unit (110) may include a keyboard, a key pad, a dome switch, a touch panel, a touch key, a mouse, a menu button, etc.

The storage unit (140) includes non-volatile storage that can preserve data (information) regardless of whether power is supplied, and volatile memory that cannot preserve data if power is not supplied and into which data to be processed by the processor (150) is loaded. The storage includes flash memory, hard-disk drive (HDD), solid-state drive (SSD), read-only memory (ROM), etc., and the memory includes buffer, random access memory (RAM), etc.

[0078] The storage unit (140) can store design material specifications, production material specifications, 3D work instructions, web / mobile work instructions, augmented reality work instructions, process planning information, process specifications, Product Data Management (PDM) system, Product lifecycle management (PLM) system, Manufacturing Execution System (MES), Employee assistance program (EAP), Recipe Parameter Management System (RPMS), etc. The storage unit (140) can store operation programs required in the process of obtaining design material specifications and production material specifications, generating 3D work instructions, linking information generated throughout the entire process from the product design stage to the production stage, generating augmented reality data and augmented reality work instructions, etc.

[0079] The processor (150) can control at least one other component (e.g., hardware or software component) of the synchronization device (100) by executing software such as a program, and can perform various data processing or operations.

[0080] According to one embodiment of the present invention, a processor (150) obtains an engineering bill of materials (E-BOM) including 3D design data for each part of a product, reconstructs the design bill of materials for each part according to a production process of the product to obtain a manufacturing bill of materials (M-BOM), generates a 3D work instruction for production of the product based on the production bill of materials, and links the design bill of materials, the production bill of materials, and the 3D work instruction so that the 3D design data of the design bill of materials and the 3D work instruction are correspondingly changed as the 3D design data of the design bill of materials are changed.

[0081] The processor (150) obtains a manufacturing bill of materials (M-BOM) by reconstructing an engineering bill of materials (E-BOM) including 3D design data for each part of a product according to the production process of the product, and generates augmented reality (AR) data to implement product assembly operations for each process step according to the manufacturing bill of materials using the 3D design data, and generates an augmented reality work instruction manual for the product using the augmented reality data.

[0082] Meanwhile, the processor (150) may perform at least a portion of the data analysis, processing, and result information generation for performing the above operations using at least one of a machine learning, neural network, or deep learning algorithm as a rule-based or artificial intelligence (AI) algorithm. Examples of the neural network may include models such as a CNN (Convolutional Neural Network), a DNN (Deep Neural Network), and an RNN (Recurrent Neural Network).

[0083] FIG. 3 is a diagram illustrating an operation flow chart of a 3D design data synchronization device according to one embodiment of the present invention.

[0084] A processor (150) according to one embodiment of the present invention can obtain a design material statement (E-BOM) including 3D design data for each part of a product (S10).

[0085] The processor (150) may receive 3D design data prepared for each component from a Product Data Management (PDM) system, a Product Lifecycle Management (PLM) system, etc., and may generate a design material specification using the 3D design data. Alternatively, the processor (150) may receive user input for generating a design material specification. In addition, the processor (150) may receive a previously generated design material specification from an external source, and the method or path for acquiring the design material specification is not limited to any one.

[0086] A processor (150) according to one embodiment of the present invention can obtain a manufacturing bill of materials (M-BOM) by reconstructing a design material specification for each component according to the production process of the product (S20).

[0087] Parts may be produced individually or in bundles, depending on factors such as production costs and the specificity of the production process. Even when multiple parts are produced in a bundle, the bundle configuration may vary from product to product. Therefore, during the production stage, a production bill of materials, reorganized from the design bill of materials for each part, is utilized, based on the process.

[0088] The processor (150) can generate a production material specification based on information about the production process, or can receive user input for reconfiguring a design material specification. Similarly, the method or path for obtaining the production material specification is not limited to any one. The processor (150) can generate a production material specification by only changing the order and arrangement of the design material specification without modifying the design material specification. In this case, when 3D design data changes, it can be easily linked to at least one of the design material specification, the production material specification, and the 3D work instructions.

[0089] A processor (150) according to one embodiment of the present invention can generate a 3D work instruction for production of a product based on a production material specification (S30).

[0090] 3D work instructions can be created using 3D design data and can include information necessary for product assembly and management, such as a description of the process for assembling a product, the names of parts included in the product, part numbers, and quantities.

[0091] According to one embodiment of the present invention, the processor (150) can link the design material specification, the production material specification, and the 3D work instructions so that the 3D design data of the production material specification and the 3D work instructions are correspondingly changed as the 3D design data of the design material specification is changed (S40).

[0092] 3D design data may be frequently changed for various reasons throughout the entire manufacturing process. At this time, the designer device (200) may receive user input for changing the 3D design data, or may receive user input for changing the 3D design data in response to a request signal for changing the 3D design data received from the manufacturer device (300) or an external source.

[0093] The method of linking data is not limited to one, and for example, the processor (150) can link design material specifications, production material specifications, and 3D work instructions by mapping them for each part.

[0094] The processor (150) may transmit a request signal to the designer device (200) based on receiving a request signal requesting a change in 3D design data from the producer device (300). When the designer device (200) receives the request signal, the designer device (200) may output notification information regarding the request content and receive user input for changing the 3D design data. In addition, the processor (150) may provide a user interface through which the designer device (200) may request synchronization according to a change in the 3D design data. At this time, the user interface may include a button for requesting synchronization, etc. However, in addition to this, various methods for receiving the synchronization signal from the designer device (200) may be employed.

[0095] Alternatively, the designer device (200) may transmit a synchronization signal to the synchronization device (100) after receiving a user input requesting change and synchronization of 3D design data without a separate external request as described above.

[0096] The processor (150) can change the 3D design data of the production material specification and 3D work instructions based on receiving a synchronization signal according to a change in the 3D design data from the designer device (200).

[0097] When the processor (150) receives a synchronization signal, it can batch (or sequentially) change the 3D design data of the production material specification and the 3D work instructions that were previously linked to the design material specification.

[0098] Meanwhile, the processor (150) can generate a bill of process (BOP) including a production material specification and product process plan information, and generate a 3D work instruction manual for product production based on the BOP. The process plan information may also include information regarding human resource management.

[0099] In this case, the processor (150) can link the process specification to the design material specification, the production material specification, and the 3D work instructions so that the 3D design data of the process specification is also synchronized.

[0100] According to one embodiment of the present invention, automatic updating of work instructions is possible by utilizing 3D design data based on the latest material specifications, thereby improving work efficiency.

[0101] According to one embodiment of the present invention, a consistent data synchronization system can be configured from product design to material specification creation, process planning, and work instruction creation, and data errors between personnel can be reduced.

[0102] FIG. 4 is a drawing illustrating the operation of a 3D design data synchronization system according to one embodiment of the present invention.

[0103] A synchronization system (1) according to one embodiment of the present invention is divided into a development phase and a mass production phase, and is interlinked so that when the 3D design data received from the PLM / PDM system changes, the 3D design data and design material specifications of the development phase are automatically updated. In addition, the design material specifications of the development phase and the production material specifications of the production phase are also interlinked, and have a structure in which they are automatically updated up to the final work instructions.

[0104] At this time, the processor (150) can link the 2D design data to the design material specification, the production material specification, and the 3D work instructions so that the 2D design data corresponding to the 3D design data is also synchronized.

[0105] The processor (150) can generate at least one of a web / mobile work guide and an augmented reality (AR) work guide using the 3D work guide. The process of generating the AR work guide is described with reference to FIG. 8, and an example of the web / mobile work guide is illustrated in FIG. 14.

[0106] According to one embodiment of the present invention, work efficiency can be improved by simplifying design, production, and manufacturing work through data tracking when development and production changes occur with a single data connection such as '3D design data → design material bill of materials (E-BOM) → production material bill of materials (M-BOM) → BOP process work instructions'.

[0107] FIG. 5 is a drawing illustrating the operation of a 3D design data synchronization system according to one embodiment of the present invention.

[0108] FIG. 5 illustrates a linking of a design material specification, a production material specification, a process specification, and a 3D work instruction manual, as described with reference to S40 of FIG. 3.

[0109] First, let's examine the 3D design data (3D CAD Model). The 3D design data for each pen component is structured. The pen consists of a body, cap, and cartridge, and the body is comprised of a barrel, tip, and top.

[0110] The electronic bill of materials (E-BOM) for design is created by including 3D design data and component-specific information. The manufacturing bill of materials (M-BOM) and process plan are created by reorganizing the design bill of materials according to the process sequence and process plan. Work instructions can be created based on the manufacturing bill of materials or process plan.

[0111] FIG. 6 is a drawing illustrating the operation of a 3D design data synchronization system according to one embodiment of the present invention.

[0112] Figure 6 shows the overall operation flow diagram of the system (1), which can be broadly divided into a 3D design BOM, a production BOM, a process plan, a production BOM and process plan BOP linkage, and a digital work instruction manual.

[0113] The synchronization device (100) can create a 3D model structure using 3D design data and use this to create a design BOM (E-BOM). A production BOM (M-BOM) can be created using the design BOM (E-BOM), and a production BOM can be linked to a process specification (BOP) by allocating a production BOM for each process task based on a process plan. At this time, component elements for each process for creating work instructions can be visualized. The 3D design data can be composed of a 3D drawing or animated data that dynamically moves the 3D drawing.

[0114] According to one embodiment of the present invention, it is expected that a paradigm shift in the product development process, improvement in design completeness, shortening of the development period, and reduction in development costs (approximately 30% reduction) will be possible.

[0115] According to one embodiment of the present invention, business communication can be facilitated through data unification between the design part and the production part.

[0116] FIG. 7 is a drawing illustrating the operation of a 3D design data synchronization system according to one embodiment of the present invention.

[0117] Referring to Figure 7, if the 3D design data for one of the product's components changes (701), the synchronization device (100) can compare the design material specification with the production material specification (702) and update the production material specification corresponding to the changed item (703). The updated information can then be reflected in the work instructions linked to the production material specification (704).

[0125] According to one embodiment of the present invention, the synchronization device (100) can generate an augmented reality work instruction manual for a product using augmented reality data (S830).

[0126] The augmented reality work instructions may include augmented reality data and a list of process steps. The synchronization device (100) may implement a user interface for displaying the list of process steps and reproducing augmented reality data for each step.

[0127] According to one embodiment of the present invention, a complex product production process can be effectively and intuitively conveyed to a production manager the three-dimensional shape of a product using augmented reality.

[0128] According to one embodiment of the present invention, efficient communication is enabled between design personnel and production personnel by utilizing visible and clear product design data.

[0130] FIG. 9 is a drawing illustrating the creation of an augmented reality work instruction manual according to one embodiment of the present invention.

[0131] First, the synchronization device (100) can preprocess 3D design data, such as by changing colors, to more easily distinguish between components. Using the preprocessed 3D design data, the synchronization device (100) can generate 3D work instructions that describe the overall assembly process. The 3D work instructions can be composed of still images and / or moving images (animations).

[0132] The synchronization device (100) can convert 3D design data into augmented reality data and implement various widgets that can be utilized in work instructions. The various functions included in the widgets are described with reference to FIG. 10. Thereafter, the synchronization device (100) can construct an augmented reality work instruction manual through the steps of operation testing, startup screen generation, and pop-up screen generation.

[0133] According to one embodiment of the present invention, 3D design data is utilized to enable production, manufacturing pre-prediction and verification in a virtual environment before manufacturing an actual product.

[0136] According to one embodiment of the present invention, augmented reality technology can be utilized not only for product assembly but also for product inspection, enabling more intuitive product reviews and feedback.

[0137] According to one embodiment of the present invention, augmenting a virtual product in augmented reality to the same level as the actual product based on 3D modeling facilitates the management and operation of the product assembly process, including comparative analysis of the digitized virtual product and the actual product. Furthermore, various data and materials (drawings, models, manuals, etc.) required for product production can be digitized.

[0138] FIG. 10 is a diagram illustrating the operation process of an augmented reality work instruction manual according to one embodiment of the present invention.

[0139] The synchronization device (100) can provide augmented reality work instructions to the manufacturer device (300) when the manufacturer device managing the production material specification recognizes identification information corresponding to the product. The identification information may be in any form, such as a QR (Quick Response) code or barcode, and it is sufficient as long as the identification information can access the augmented reality work instructions for the corresponding product.

[0140] The synchronization device (100) can provide a user interface that can be configured to play the product assembly operation of each process step or the entire process step of the augmented reality work instructions in a forward or reverse direction. By providing the product assembly operation in a forward direction according to the assembly order, the production manager's understanding of product assembly can be improved, and by providing it in a reverse direction according to the disassembly order, the usability of the augmented reality work instructions can be further increased, such as by utilizing it for product reassembly and maintenance. In addition, the synchronization device (100) can provide a user interface that can be configured to zoom in / out and rotate the product implemented as augmented reality in the augmented reality work instructions.

[0141] Below, the augmented reality work instruction screens displayed on the producer device (300) are described. It should be understood that the information, design, form, etc. contained in the screens are not limited to this example.

[0142] First, the first screen (1001) may be a start screen that displays a product photo and product name, and may include a start button that starts the augmented reality operation instructions.

The second screen (1002) displays a product implemented in augmented reality in the center, and includes, from the left, a process step list pop-up button, a zoom in / out scroll bar, a rotation scroll bar, and a function pop-up button. When the producer device (300) receives a user input for pressing the process step list pop-up button, it can display or hide the process step list, and when it receives a user input for dragging the zoom in / out and rotation scroll bars, it can zoom in / out and rotate the product implemented in augmented reality. In addition, the augmented reality work instructions may include various functions, and the function list can be displayed or hidden by pressing the function pop-up button.

[0144] The third screen (1003) displays a list of process steps and a list of functions. When the producer device (300) receives a user input for selecting any one process step from the list of process steps, it can reproduce augmented reality data that implements the product assembly operation of the corresponding step.

[0145] In addition, when the producer device (300) receives a user input for selecting a function button such as stepwise forward play, stepwise reverse play, full forward play, full forward play, pause, or exit, the augmented reality work instructions perform an action corresponding to the function. A function for adjusting the animation speed according to the function button is also included.

[0148] The screen (1101) of Fig. 11 shows an image captured by the camera of the producer device (300), with the left side displaying an actual product and the right side displaying a virtual product implemented through augmented reality. In this way, the synchronization device (100) can implement an augmented reality work guide so that the actual product captured by the camera of the producer device (300) and the augmented reality product are displayed together.

[0149] The synchronization device (100) can display augmented reality work instructions superimposed on the image captured by the camera of the producer device (300). The screen (1102) of FIG. 11 is an augmented reality product in which the process step list described in FIG. 10 is superimposed and displayed. When the producer device (300) receives user input for selecting each step, it can reproduce augmented reality data that implements the product assembly operation of the corresponding step.

[0150] As shown in screen (1103), the synchronization device (100) can recognize the shape of an actual product and implement an augmented reality work instruction manual to inspect the assembly status of the actual product. At this time, as shown in screen (1104), guidelines implemented in augmented reality for inspecting the assembly status can be displayed. Additionally, as shown in screen (1105), two or more products can be compared.

[0151] According to one embodiment of the present invention, when reviewing product assembly and quality inspection through AR work instructions, it is possible to easily identify areas where problems occur during various operations, and the history of inspection is reflected in the work instructions, providing convenience to the design manager.

[0152] FIG. 12 is a drawing illustrating the function of an augmented reality work instruction manual according to a second embodiment of the present invention.

[0153] The list pop-up screen allows for detailed breakdowns of sub-assembly steps according to the assembly structure. Figure 12 shows augmented reality work instructions for the base case. While Figure 12 presents still images in a sequential order, the assembly process can actually be displayed sequentially in animation form.

[0154] At this time, by displaying the 3D design data colors of the parts to be assembled for each process in a distinct manner, the current production manager can check at a glance which parts should be assembled where.

[0155] Figure 13 is a photograph showing the use of an augmented reality work guide according to one embodiment of the present invention.

[0156] Referring to Figure 13, a production manager displays an augmented reality work instruction manual on the manufacturer's device (300) and assembles the product by referring to it. Utilizing the 3D model-based augmented reality work instruction manual allows for direct comparison between the augmented reality product and the actual product, thereby reducing work errors and improving production efficiency.

[0157] According to one embodiment of the present invention, collaboration, such as sharing various types of data, is facilitated through augmented reality (AR) technology and digitized data, and work efficiency is improved through clear decision-making through product monitoring and feedback.

[0158] According to one embodiment of the present invention, even production personnel with low work skills can easily perform tasks using intuitive augmented reality work instructions.
