Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent manufacturing, and specifically relates to a 3D collaborative design system and a design method for industrial products. Background Art

[0002] As we all know, 3D is the abbreviation of three-dimensional, which means three-dimensional graphics. Displaying 3D graphics on a computer is to display three-dimensional graphics on a plane. Unlike the real world, the real three-dimensional space has real distance space. The computer just looks very similar to the real world, so the 3D graphics displayed on the computer are more realistic to the naked eye. The naked eye has a characteristic that things that are closer appear larger and farther away appear smaller, which creates a sense of three-dimensionality. The computer screen is two-dimensional. The reason why we can appreciate three-dimensional images that are as real as real objects is that the different color grayscales when displayed on the computer screen cause the human eye to have a visual illusion and perceive the two-dimensional computer screen as a three-dimensional image.

[0003] Especially for industrial products with complex structures, flat two-dimensional graphics cannot fully display the details and internal structural relationships of the products, which also imposes certain restrictions on the design of industrial products. Statistics show that in the development and production process of modern industrial products, 70% of errors have occurred in the design stage, while 80% of errors are often discovered and corrected in production or later stages. The outstanding advantage of 3D is that it can maximize the simulation design of products and user communication, solve errors and demand changes as early as possible in the design stage, shorten the product development cycle, reduce production costs, and enhance the company's market competitiveness.

[0004] On the other hand, the introduction of the collaborative design engine has helped establish unified design standards for industrial product design, including layers, colors, line types, print styles, etc. On this basis, all design disciplines and personnel can design on a unified platform, thereby reducing the errors, omissions, collisions and deficiencies caused by poor or untimely communication between disciplines (and within disciplines), truly realizing the uniformity of all drawing information elements, achieving automatic modifications to other areas when modifications are made in one place, and improving design efficiency and quality.

[0005] The existing technology is that the industrial product 3D collaborative design engine is based on the Three.js rendering library, which can edit the assembly relationship of industrial products and imported models online, and can quickly and easily complete the 3D modeling of industrial products; the assembly constraint technology based on the directed graph is used to realize the visual combination of assembly relationships; the event-driven 3D rendering technology is used to optimize the original large-scale and multi-frequency model rendering to 3D rendering driven by event operations, thereby reducing the multi-frequency rendering changes; the camera plane-based scene measurement technology is used to improve the measurement method of point selection and distance measurement based on objects, and realize scene distance measurement based on multiple assumed planes; the plane projection generation technology of the grid model is introduced to perform point-to-plane projection of the 3D stereo model; the plug-in rendering engine based on event scheduling is used to realize the multi-functional combination of model assembly relationships based on functional improvements.

[0006] The defect is that it only provides a single client service, which cannot meet the current needs of Internet collaborative work, and the learning cost is high for non-professionals; on the other hand, since the simple assembly and construction of industrial product 3D models cannot fully cover the production operation needs in the industrial field, the combined engineering drawings of 3D models and actual production processes have become a technical defect that needs to be urgently solved in this invention.

[0007] The difficulty and significance of solving the above technical problems: At present, in the field of industrial product processing and manufacturing, there are problems such as long time cycle, unequal demand, and defective product design in the early stage of customer demand docking, which leads to longer product sales cycle and serious waste of time cost. The introduction of the industrial product 3D collaborative design engine builds a bridge of communication between customers and sales and design engineers. Customers can use the existing product models of the engine to perform simple model editing according to their needs, and engineers will assist in online design. Finally, the product drawing BOM list is generated and exported to guide factory production. Improve the efficiency of industrial product design, quickly produce drawings and quotes, shorten the sales cycle, improve corporate benefits, reduce the workload of engineers, and avoid repetitive work.

[0068] The engine provides customers with an editable front-end application for hosting various modules in the manager;

[0069] The renderer is used to perform basic rendering on the model components designed and edited by the user; the entire rendering process of the industrial product 3D collaborative design engine is as follows Figure 4 As shown in the figure, the renderer, as the middleware between the system and the large-screen device, renders the complex engine instructions and operation history through basic rendering and presents them on the front-end large screen for display;

[0070] Event management provides a variety of event-driven rendering management methods, which implements model rendering by creating events;

[0071] The history record is used to record the user editing process;

[0072] The engine configuration is used to perform basic configuration of the industrial product 3D collaborative design engine;

[0073] The usage scenarios of industrial product 3D collaborative design engine are as follows: Figure 3 As shown, the user types involved are customers, front-end / sales, engineers, and factory operators.

[0074] like Figure 7 As shown, it is a multi-terminal coordination framework diagram of the present invention. The entire industrial product 3D design and physical production involves the sales end (including the client end), the factory end and the engineer end;

[0075] As the third user of the industrial product 3D collaborative design engine, the front-end / sales department generates corresponding product models according to the requirements of the first user (customer). The product models are designed and made by the second user (engineer) based on years of experience and past factory production cases. At the same time, the second user assists the third user in collaboratively designing product models according to the requirements of the first user.

[0076] The first user customizes the product model according to his actual needs, generates the corresponding product drawing BOM list and sends it to the third user;

[0077] After the third user confirms the BOM list, a sales order is generated and initiated;

[0078] The sales order is decomposed within the factory and sent to the factory site in the form of production BOM;

[0079] On-site operators carry out processing and production according to the production BOM;

[0080] The finished product is sent to the first user in the form of order delivery;

[0081] Specifically, the usage logic of the industrial product 3D collaborative design engine is as follows: Figure 5 As shown, the model component designed by the second user through the engine module is stored in the form of a template library and imported into the industrial product 3D collaborative design engine;

[0082] The third user imports the corresponding product model according to the collected requirements, performs multi-model editing in the industrial product 3D collaborative design engine, and exports the model files in .dxf / .stl and other formats;

[0083] The industrial product 3D collaborative design engine is used to interpret product model files in various formats, extract model information, and generate product drawing BOM lists;

[0084] The industrial product 3D collaborative design engine is also used to generate corresponding PDF engineering drawings based on model information for factory operators to process and use.

[0085] The following uses crane design and linkage with factory production as an example to further illustrate the technical solution of the present invention.

[0086] Since the technical parameters of a crane characterize the crane's operating capacity, they are the basic basis for designing a crane. Therefore, during the product design process, if industrial product parameters or component parameters change, the corresponding product will also change. The present invention manages the designed component / accessory model based on the accessory parameters. When the first user modifies the parameters according to the needs, the system will automatically match the corresponding industrial product components, and the first user will generate a customized industrial product through a simple industrial product assembly relationship.

[0087] The second user creates an assembly building request in the collaborative design engine module, which can call the manager module to automatically build a grid-assisted design scene. The second user calls the event management module based on fixed crane design parameters and can create accessory / parts models based on the auxiliary scene by simply dragging. The model information is displayed through the renderer module, which performs front-end rendering of the second user's basic operations. To ensure the accuracy of the accessory information, the rendered model can be measured and annotated in length, angle, etc. based on the annotation and measurement modules.

[0088] The linkage model module can adjust the model parameters to change the inherent properties of the model. The edited model can be stored in the model library as a crane accessory or a finished product. There is a one-to-one mapping relationship between the accessory parameters and the parts stored in the model module.

[0089] like Figure 8 As shown, it is a linkage production logic diagram of the present invention;

[0090] 1: The first user sends a query request to the model library according to the crane parameter requirements, and the model library feeds back the corresponding model information;

[0091] 2: Import the model information into the industrial product editing client;

[0092] 3: The linkage manager module and event management module adjust the parameters of accessories / components, such as material, color, and rail type. The parameter modification request is sent to the model module. The industrial product 3D collaborative design system automatically responds to the mapping relationship between the parameters and the model, and displays it through the renderer;

[0093] The adjusted crane parts model is fed back to the collaborative design engine module, which links the assembly module. Through simple event operations, the parallel, overlapping and vertical assembly relationships of the parts are triggered. The assembled crane model is automatically stored in the industrial product construction and editing client.

[0094] 4: After the first user confirms that the crane model design is correct in the industrial product building editing client, the projection module is linked to disassemble the 3D model into 2D and split it into three views. The three views are then fed back to the finished product editing module. The industrial product 3D collaborative design system automatically generates a BOM table with three views, which includes accessory parameters, instructions, etc.

[0095] The third user logs into the finished product editing module of the industrial product 3D collaborative design system, selects the corresponding crane BOM table, and generates the corresponding sales order;

[0096] 5: The sales order is disassembled through the process and sent to the factory site in the form of a process BOM. The on-site operator delivers the finished crane to the first user through a long-term crane processing. The innovation of this application is reflected in:

[0097] ① Focus on the real-time visualization of industrial product parameters. In the pre-sales stage, the specific angles and appearance designs of industrial products can be displayed, and the important parameters of industrial products can be marked for reference by sales and factory operators;

[0098] ② Based on the technical innovation of cloud services, the industrial product 3D collaborative design system follows J2EE rules, uses JavaScript+Vue.js as the main development tools, adopts the main BS architecture Web application mode, uses SVG technology to draw industrial product styles at specific angles, and exports them in PDF format to achieve controllability of drawing quality and file size;

[0099] ③ Break through the professional knowledge barriers between customers and design engineers. Customers can meet customized needs through self-assembly and construction, while helping design engineers save time on repetitive tasks.

[0100] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention.
