Description

Technical Field

[0001] The present application relates to the technical field of vehicle design and manufacturing, and in particular to a method, device, equipment and medium for synchronous management and automatic conversion between BOMs. Background Art

[0002] EBOM is the source of part definition and product structure definition. In the process of product structure definition, some of the needs of manufacturing and assembly processes are taken into consideration. The CAD-BOM structure is consistent with the EBOM structure. In the process of converting from EBOM to MBOM, it is necessary to change the EBOM data structure in combination with the needs of manufacturing and assembly processes, define some process components, and then manually specify data such as part manufacturing routes, assembly workshops, and implementation dates. CAD-BOM refers to the configured BOM (Bill of Materials) associated with 3D digital models managed in CAD software to achieve the selection of digital model assembly results of a certain product by configuration; EBOM refers to the product design department describing the composition of the product from a design perspective, showing all parts, raw materials and other data of the product composition; MBOM is a BOM data structure established from the perspective of assembly and manufacturing based on EBOM, adding information such as the manufacturing location of the parts, the workshop where they are used, and the validity period of use in the factory.

[0003] When defining process assemblies, the BOM data needs to be reassembled or decomposed, which makes it difficult to achieve complete correlation mapping or effective linkage between EBOM and MBOM. In this case, some MBOM definitions need to be entered manually, and in the daily management process, regular manual verification is required to ensure the consistency of EBOM and MBOM data. In addition, since the assembly definition is only defined in MBOM, it means that there is no relevant data in EBOM / CAD-BOM, nor the 3D digital model data of the assembly, and the technical documents related to the assembly cannot be stored in the vehicle structure tree, resulting in a lack of definition.

[0004] Furthermore, in order to ensure that the EBOM structure is consistent with the CAD-BOM structure and MBOM structure data, only the definition of the assembly required by the manufacturing and assembly process is completed in the EBOM; when constructing the MBOM, only the part manufacturing route, assembly workshop, and implementation date data information need to be manually specified. However, since various cross-disciplinary / multiple designers are directly defined in the early stages of the project, the maturity of the parts definitions of different disciplines / different designers is different, which affects the design delivery progress of each discipline / designer. At the same time, since the process assembly may integrate parts from multiple disciplines, it cannot meet the needs of different professional designers in different business scenarios to quickly query and be authorized to update the definition; during the MBOM construction process, it is also necessary to manually add data such as part manufacturing routes, workshops, and implementation dates, which makes the efficiency and accuracy of MBOM construction poor. Summary of the invention

[0005] The present application provides a method, device, equipment and medium for synchronous management and automatic conversion between BOMs, which can improve the construction efficiency and accuracy of MBOM, and at the same time realize the control of production quality in the field of product design, ensuring that the produced vehicles meet the product design requirements.

[0043] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0045] On the one hand, the embodiments of the present application provide a method for synchronous management and automatic conversion between BOMs. On the basis of ensuring the linkage and synchronization between CAD-BOM, EBOM, and MBOM data: (1) a complete product design and development environment is built to meet the needs of different professional designers to independently manage the parts they are responsible for and complete the formalization of the design of parts in this field as soon as possible. At the same time, it also meets the needs of recombining any number of parts according to the requirements of production and assembly processes; (2) the needs of professional designers, process engineers and other project members to quickly identify and find parts in various business scenarios are met, including viewing product data in various ways such as by design profession, by physical space location, and by assembly workshop; (3) based on EBOM as the basic framework, MBOM data is fully automatically generated, the efficiency of MBOM construction is improved, and the accuracy and timeliness of MBOM are guaranteed, so as to ensure that the products produced by the factory meet the design requirements.

[0046] In one embodiment, referring to Figure 1 , Figure 1 The following is a flowchart of the method for synchronous management and automatic conversion between BOMs in this application. Figure 1 As shown in the figure, the synchronous management and automatic conversion methods between BOMs include:

[0047] S1: Parts are divided based on design disciplines to construct an EBOM structure tree of the first structure type, and parts are divided based on assembly areas to construct an EBOM structure tree of the second structure type; the level and quantity of design disciplines can be customized and adjusted at any time; the assembly area includes the assembly workshop and assembly station area.

[0048] Specifically, the EBOM structure tree of the first structure type is constructed by dividing according to the design specialty or sub-specialty of the parts. The types of design specialties can be defined at any level and in any number as needed, and can be adjusted at any time. The EBOM structure tree of the second structure type is constructed by dividing according to the assembly workshop and assembly station area of ​​the parts. For example, the passenger car industry can be divided into stamping workshop, welding workshop, painting workshop, and assembly workshop.

[0049] S2: Divide the parts based on their physical spatial positions in the product, construct a CAD-BOM structure tree, and define the physical spatial positions as structural nodes of the CAD-BOM structure tree;

[0050] Specifically, the components are divided according to their physical spatial positions in the product, thereby constructing a CAD-BOM structure tree.

[0051] In actual applications, the above-defined design specialty, assembly area, and physical space position in the product can be called the structural nodes of the product structure tree. For example, the EBOM structure tree of the first structure type includes the structural nodes - body structure, structural node - body equipment, structural node - chassis specialty, structural node - power specialty, structural node - electrical specialty, and the structural node - electrical specialty can also include the structural node - vehicle system; the EBOM structure tree of the second structure type includes the structural nodes - stamping workshop, structural node - welding workshop, structural node - paint workshop, and structural node - final assembly workshop; the CAD-BOM structure tree includes the front protection area, windshield hood area, side area, top area, and rear area.

[0052] S3: Set the type of the component function node, define the component function node under the corresponding structure node, and define the component function node on the EBOM structure tree;

[0053] Specifically, the types of component function nodes in this application include BOM general components, BOM assembly components, and BOM assembly assemblies, so as to facilitate the consistency check between the two EBOM structures. The EBOM structure tree of the first structure type includes BOM general components and BOM assembly components; the EBOM structure tree of the second structure type includes BOM general components, BOM assembly components, and BOM assembly assemblies.

[0054] Further, in one embodiment, the definition of component function nodes is performed on the EBOM structure tree, specifically including:

[0055] S301: Complete the definition of component function nodes on the EBOM structure tree of the first structure type, including design deformation nodes, component function definitions, and component supplier definitions;

[0056] S302: According to the correspondence between the component function node and the assembly workshop, a corresponding component function node is added under the assembly area in the EBOM structure tree of the second structure type; of course, the added component function node can be directly effective or modified.

[0057] For example, the first component function node and the second component function node are defined under the structure node - vehicle system of the EBOM structure tree of the first structure type, the first component function node corresponds to the BOM general component, and the first component function node specifically includes the design deformation node, the part function definition, and the part supplier definition; the second component function node corresponds to the BOM assembly component, and the second component function node specifically includes the design deformation node, the part function definition, and the part supplier definition. Correspondingly, the third component function node and the fourth component function node are defined under the structure node - assembly workshop of the EBOM structure tree of the second structure type, wherein the third component function node defined under the structure node - assembly workshop corresponds to the first component function node defined under the structure node - vehicle system, and the fourth component function node defined under the structure node - assembly workshop is a BOM assembly assembly, and the fourth component function node includes the design deformation node, the part function definition of the assembly, and the part function definition of the sub-component.

[0058] S303: defining component function nodes into the CAD-BOM structure tree according to the physical space position;

[0059] It should be noted that the component function nodes in the EBOM structure tree of the first structure type and the EBOM structure tree of the second structure type both constitute complete products, and the structure under the component function node is consistent in the CAD-BOM structure tree, the EBOM structure tree of the first structure type, and the EBOM structure tree of the second structure type.

[0060] S4: Complete the design and validation of the newly developed parts according to the CAD-BOM structure tree, and automatically convert the EBOM structure tree of the second structure type to the MBOM.

[0061] Furthermore, in one embodiment, the design and validation of the newly developed parts are completed according to the CAD-BOM structure tree, specifically including:

[0062] S401: Complete the 3D design and validation of the newly developed parts under the corresponding design deformation node on the CAD-BOM structure tree;

[0063] Specifically, the designer completes the 3D design and validation of the newly developed parts under the corresponding design deformation node on the CAD-BOM structure tree;

[0064] S402: Design deformation nodes, part function definitions, part supplier definitions, the relationship between part function nodes and design deformation nodes, and the definition of design deformation nodes and part function definitions can be defined separately or together, and become effective and published. This greatly reduces the time wasted by product designers when waiting, and after the definition is published, it will be simultaneously effective on the CAD-BOM structure tree, the EBOM structure tree of the first structure type, and the EBOM structure tree of the second structure type, and the process assembly definition only needs to be effective in the EBOM structure tree of the second structure type.

[0065] Further, in one embodiment, the automatic conversion of the EBOM structure tree of the second structure type into the MBOM specifically includes:

[0066] S411: Automatically generate MBOM based on the EBOM structure tree of the second structure type, the component route allocation table, the component function node, and the component use workshop rules; if the manufacturing route has multiple values, the user is allowed to manually select them to take effect; the component route allocation table contains information including component number, assembly workshop, manufacturing route, start date, and end date.

[0067] S412: Keep the manufacturing route in the component route allocation table consistent with the part supplier information in the EBOM structure tree, and keep the component use workshop consistent with the assembly area in the EBOM structure tree of the second structure type. That is, keep the component use workshop consistent with the assembly workshop in the EBOM structure tree of the second structure type.

[0068] Furthermore, in one embodiment, after the automatic conversion of the EBOM structure tree of the second structure type to the MBOM, the BOM structure is also adjusted. Specifically, when the structure of the parts in the BOM needs to be adjusted, the type of the part function node of the part to be adjusted is updated in the EBOM structure tree of the first structure type, and the EBOM structure tree and the CAD-BOM structure tree of the second structure type are adjusted accordingly. The CAD-BOM structure tree, the EBOM structure tree of the first structure type, and the EBOM structure tree of the second structure type are independent of each other, and the consistency of the design deformation and part definition under various BOMs is ensured through the part function node.

[0069] The method for synchronous management and automatic conversion between BOMs in the embodiment of the present application enables, during the project development stage, each professional product designer to quickly complete the deliverables of their profession around the goals of project decomposition, without being affected by the maturity progress of part design in other fields, thereby reducing the waste of waiting time during the design and development process of product personnel, and helping project managers to quickly identify real problem obstacles and build a complete product design and development environment; it can help project members to quickly and conveniently query, browse or filter relevant data according to actual needs; the automatic construction of MBOM and data synchronization are completed through the EBOM structure tree of the second structure type, which not only improves the construction efficiency and accuracy of MBOM, but also indirectly realizes the control of production quality in the field of product design, ensuring that the produced vehicles meet the product design requirements and meet the requirements of fast automotive software updates and iterations and no implementation confusion on site.
