Description

Technical Field

[0001] This invention relates to the field of product data processing technology, and in particular to a method and system for maintaining PBOM process manufacturing information. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] In recent years, with the deepening of enterprise digital transformation, the launch of new R&D products, and the increasing demand for personalized customer services, enterprises are facing greater challenges in BOM (Bill of Materials) data processing and management. As product launches accelerate and market competition intensifies, higher demands are being placed on product data quality and product manufacturing cycles.

[0004] Currently, the maintenance of process manufacturing information in PBOM (Bill of Materials) generally relies on manual judgment of each component based on design drawings. However, the process information in PBOM is inherently complex and variable. For products that have already been manufactured, the system cannot effectively read the process values ​​of their original components, resulting in repetitive maintenance. This leads to long PBOM maintenance cycles, poor quality, and seriously affects product manufacturing costs and production cycles.

[0005] Therefore, how to achieve rapid retrieval, accurate allocation, and batch maintenance of process manufacturing information after converting EBOM (Design Bill of Materials) to PBOM has become an urgent problem to be solved. Summary of the Invention

[0006] To overcome the shortcomings of the prior art, this invention provides a method and system for maintaining PBOM process manufacturing information, enabling customization and visualization of component processes, rapid retrieval of product processes, accurate and rapid identification of components in the product that have not been assigned processes, and batch maintenance of component assembly processes based on output values. This solves the problems of existing technologies that generally rely on manual labor, resulting in long PBOM maintenance cycles and poor quality.

[0007] To achieve the above objectives, one or more embodiments of the present invention provide the following technical solutions: The first aspect of this invention provides a method for maintaining PBOM process manufacturing information, comprising: Obtain the PBOM generated after EBOM conversion; Based on the method of acquiring the components, the component attributes in the PBOM are set to virtual components, self-made components, and outsourced components, and the target components that need to be maintained are filtered out. The target component is divided into three parts according to the assembly process flow: fixed assembly process A, variable assembly process B, and line change process C. For component A with fixed assembly process, the fixed process code is maintained in its component attributes through the PLM platform and automatically read and displayed when the PBOM is expanded; for component B with variable process and component C with changeover process, the unassigned process is filtered out through the search function of the PLM platform, and batch process maintenance is performed on them, and the maintained process code is automatically displayed in the corresponding field of the PBOM. Perform an integrity check on the PBOM that has completed the maintenance process. Once the check is passed, publish it to the ERP system for automatic aggregation.

[0008] As a further technical solution, the step of screening out the target components that need to be maintained specifically includes: in the PBOM structure tree, when traversing to a virtual component, only the self-made components and outsourced components in the lower layer after its expansion are obtained as target components, and the expansion of other virtual components in the lower layer of the virtual component continues until the self-made components or outsourced components are obtained.

[0009] As a further technical solution, the fixed assembly process A component refers to a component whose assembly process does not change with product configuration or production line changes during the product life cycle; the variable process B component refers to a component whose assembly process changes with product configuration or manufacturing structure changes; and the line change process C component refers to a component whose assembly process changes with different production lines.

[0010] As a further technical solution, the processing of fixed assembly process A component specifically includes: setting a fixed process field in the component attribute table of the PLM platform, pre-maintaining the process code of fixed assembly process A component in this field, and when the PBOM is expanded hierarchically, the PLM platform automatically reads the value of this field and maintains it in the fixed process sequence of the PBOM.

[0011] As a further technical solution, the retrieval information of the retrieval function includes material number, fixed process, line change process, process number and component type, and the built-in search engine supports fuzzy search and keyword matching search.

[0012] As a further technical solution, the batch process maintenance of component B for the changeover process and component C for the line changeover process specifically includes: selecting multiple components that have been filtered through retrieval, assigning corresponding process codes to the selected components through the batch maintenance function, and the PLM platform automatically displaying the process codes in the sorted string column or the line changeover sequence of the PBOM.

[0013] As a further technical solution, the integrity check includes: traversing all the lower-level self-made parts, purchased parts, and outsourced parts of the product after expanding all virtual parts in the PBOM structure tree; when the PLM platform finds that the fixed assembly process code, variable process code, and line change process code of a certain part are all empty values, the PLM platform outputs the corresponding upper-level virtual parts of the lower-level self-made parts, purchased parts, or outsourced parts in the report for maintenance again, thereby realizing the integrity check.

[0014] A second aspect of the present invention provides a system for maintaining PBOM process manufacturing information, comprising: The list preparation module is configured to: obtain the PBOM generated after EBOM conversion; set the component attributes in the PBOM to virtual components, self-made components, and outsourced components according to the component acquisition method; and filter out the target components that need to be maintained in the process. The classification management module is configured to divide the target component into three parts according to the assembly process flow: fixed assembly process A part, variable assembly process B part, and line change process C part. The automatic reading and batch maintenance module is configured as follows: for fixed assembly process A component, the fixed process code is maintained in its component attributes through the PLM platform and automatically read and displayed when the PBOM is expanded; for variable process B component and changeover process C component, the unassigned process component is filtered out through the search function of the PLM platform, and batch process maintenance is performed on it, and the maintained process code is automatically displayed in the corresponding field of the PBOM. The verification module is configured to perform an integrity check on the PBOM that has completed the process maintenance, and publish it to the ERP system for automatic aggregation after the check passes.

[0015] A third aspect of the present invention provides a computer-readable storage medium having a program stored thereon, which, when executed by a processor, implements the steps of a method for maintaining PBOM process manufacturing process information as described in the first aspect of the present invention.

[0016] The fourth aspect of the present invention provides an electronic device including a memory, a processor, and a program stored in the memory and executable on the processor, wherein the processor executes the program to implement the steps in a method for maintaining PBOM process manufacturing process information as described in the first aspect of the present invention.

[0017] The above one or more technical solutions have the following beneficial effects: This invention enables batch maintenance of component assembly processes based on the target components with empty process codes of self-made components and purchased / outsourced components after the virtual components are expanded in the PLM platform. It can achieve customized and visualized component processes, rapid retrieval and verification of product processes, and accurate and rapid identification of components in the product that have not been assigned process codes.

[0018] This invention provides a systematic and standardized operation based on the analysis of manufacturing process steps for product components, categorizing them into three types according to manufacturing technology. The first type is fixed assembly processes, whose process codes are maintained in the component attributes and automatically retrieved by the system. The second type consists of components with variable manufacturing processes; the system performs batch maintenance of these variable components based on assembly relationships. The third type includes line-change processes set according to different production lines, enabling maintenance of process differences across different production lines. The system allows for rapid retrieval of these component processes. The system can perform searches for manufacturing process numbers, unassigned processes, and assigned processes. This invention replaces manual component-by-component inspection and production process maintenance, significantly reducing PBOM maintenance time, lowering manual workload, significantly improving the quality of PBOM production processes, comprehensively enhancing PBOM production process quality and efficiency, reducing labor costs, increasing single-batch order efficiency, and ultimately shortening the production cycle.

[0022] It should be noted that the following detailed descriptions are exemplary and intended to provide further illustration of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0023] It should be noted that the terminology used herein is for the purpose of describing particular implementations only and is not intended to limit the exemplary implementations of the present invention.

[0024] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0025] Example 1 like Figure 1 As shown, based on a PLM platform, this embodiment discloses a method for maintaining PBOM process manufacturing information, including: Step 1: Preparation checklist: Obtain the PBOM generated after EBOM conversion.

[0026] Step 2: Define component process attributes: Based on the component acquisition method, set the component attributes in PBOM to virtual components, self-made components, and outsourced components according to process component attributes, and filter out the target components that need to be maintained in the process.

[0027] Step 3, Classification Management: Divide the target parts into fixed assembly process parts A, variable assembly process parts B, and line changeover process parts C according to the assembly process flow.

[0028] Step 4, Automatic Reading and Batch Maintenance: For fixed assembly process A component, the fixed process code is maintained in its component attributes through the PLM platform and automatically read and displayed when the PBOM is expanded; for variable process B component and changeover process C component, the unassigned process component is filtered out through the search function of the PLM platform, and batch process maintenance is performed on it, and the maintained process code is automatically displayed in the corresponding field of the PBOM.

[0029] Step 5, Retrieval and Verification: Perform an integrity check on the PBOM that has completed process maintenance. Once the check passes, publish it to the ERP system for automatic aggregation.

[0030] Specifically, In step 1, the PBOM data generated after EBOM conversion is first obtained from the PLM platform, completing the initial PBOM data preparation. For example... Figure 2 As shown, the PBOM contains structural information, hierarchical relationships, and attribute information of the components. The platform reads the entire product's PBOM structure and displays it in the component structure tree on the left.

[0031] In step 2, components are categorized based on their acquisition method into virtual components, self-made components, and outsourced components. In this embodiment, the maintenance of the component manufacturing process only applies to the first layer of virtual component expansion levels, specifically those components acquired through self-made or outsourced methods.

[0032] The system filters out the target components for each product assembly that require process maintenance. The specific filtering rules are as follows: when traversing the PBOM structure tree to a virtual component, if a virtual component is encountered, it is expanded. The platform only retrieves its directly subordinate self-made and outsourced components as target components requiring process maintenance. For other virtual components below the virtual component, the expansion continues downwards until a self-made or outsourced component is found. When a component's attribute is self-made or outsourced, it is set to BOM (Bill of Materials) and no further expansion is performed. This allows for quick and accurate reading of the component list requiring assembly process maintenance. The PBOM assembly process division list and relationship definition are as follows: Figure 3 As shown.

[0033] In step 3, The target components selected in step 2 are divided into three categories: components with fixed assembly processes (A), components with variable processes (B), and components with line changeover processes (C). Specifically: A fixed assembly process A component refers to a component whose assembly process does not change with changes in product configuration or production line during the product life cycle; the process code corresponding to a fixed assembly process A component remains the same even after changes in production line or product.

[0034] A variable process component B refers to a component whose assembly process changes as the product, order configuration, and manufacturing structure change. The process code corresponding to a variable process component B will change synchronously with production line adjustments, differences in product and component structure, or when it appears in multiple different components.

[0035] Component C in the line changeover process refers to a component whose assembly sequence changes depending on the production line, and whose assembly process changes accordingly when different production lines are used. Due to production scheduling, production line switching, or process adjustments, component C in the line changeover process needs to be transferred between different production lines for assembly. Its assembly process and process code are adjusted accordingly as the production line changes.

[0036] In step 4, process maintenance is performed on the three types of target components respectively: like Figure 4 As shown, for component A with a fixed assembly process: a fixed process field is set in advance in the component attribute table of the PLM platform, and the fixed process code X of component A is maintained in this field to realize the process customization of the parts.

[0037] like Figures 5-6 As shown, when the PBOM structure is expanded hierarchically, the platform automatically reads the value of the fixed process field and displays it in the "Fixed Process" column of the expanded PBOM, eliminating the need for manual re-entry.

[0038] For component B of the changing process and component C of the line change process: like Figure 11 As shown, the platform provides a component process search function, which can search for components with assigned processes, components without assigned processes, and components with empty process values. Search information includes material number, fixed process, changeover process, process number, component type, etc. The built-in search engine supports fuzzy search and keyword matching. Through the "Unassigned Process Component Search" function, all variable process B components and changeover process C components that have not yet been assigned processes can be quickly filtered out.

[0039] like Figure 7 The image shows the interface before the maintenance of the change process for component B. At this time, the "Sort String" column is empty. Figure 8 As shown, after selecting multiple variable process components B that need to be maintained, the batch process maintenance function is executed, and the variable process code Y is assigned to the selected components. The platform automatically displays the process code Y in the corresponding "sort string" field after the PBOM is expanded.

[0040] like Figure 9 As shown, for component C of the line changeover process, after selecting the component that needs maintenance, execute the batch process maintenance function and fill in the line changeover process code Y into the corresponding "line changeover process" field after the PBOM is expanded.

[0041] In this embodiment, the above-mentioned batch maintenance function can realize the rapid retrieval of product processes, accurately and quickly identify the parts in the product that have not been assigned processes, realize the customization of fixed processes of parts, batch maintenance of products with different variable processes, and realize the maintenance of process differences between different production lines.

[0042] In step 5, after all the manufacturing processes of the PBOM component have been completed, such as... Figure 10 As shown, the process information for components of categories A, B, and C is displayed in the corresponding fields of the PBOM. After the processes for these three component categories are published to the ERP system, they will be automatically summarized into a single column of values, in the following order: fixed process, sorting string, and line change process. If all three values ​​are maintained, the last process number will be read. Specifically: Before release, a completeness check is performed on the PBOM, including: traversing all the lower-level self-made parts, purchased parts, and outsourced parts after expanding all virtual parts of the product in the PBOM structure tree; when the PLM platform finds that the fixed assembly operation code, variable operation code, and line change operation code of the part are all empty values, the PLM platform outputs the corresponding upper-level virtual parts of the lower-level self-made parts, purchased parts, and outsourced parts in the report, thereby realizing the completeness verification of the PBOM operation code.

[0043] Determine if the integrity check passes. If it fails, return to step 4 to re-maintain the process for the unassigned parts. If the check passes, publish the PBOM to the ERP system. The three types of processes are automatically summarized according to the logic of fixed process, sorted string, and line change process, thus completing the entire process information maintenance process of the manufacturing process.

[0044] In this embodiment, each time the PBOM process manufacturing information of an order is maintained, the order BOM information needs to be reread through the BOM process maintenance port to match the associated field values ​​set and maintained above, and the system will retrieve the relevant information.

[0045] Example 2 This embodiment discloses a system for maintaining PBOM process manufacturing information, including: The manifest preparation module is configured to: obtain the PBOM generated after EBOM conversion; The attribute definition module is configured to: set the component attributes in the PBOM to virtual components, self-made components, and outsourced components according to the component acquisition method, and filter out the target components that need to be maintained in the process. The classification management module is configured to divide target components into three categories according to the assembly process: fixed assembly process A component, variable assembly process B component, and changeover process C component. The automatic reading and batch maintenance module is configured as follows: for fixed assembly process A component, the fixed process code is maintained in its component attributes through the PLM platform and automatically read and displayed when the PBOM is expanded; for variable process B component and changeover process C component, the unassigned process component is filtered out through the search function of the PLM platform, and batch process maintenance is performed on it, and the maintained process code is automatically displayed in the corresponding field of the PBOM. The verification module is configured to perform an integrity check on the PBOM that has completed the process maintenance, and publish it to the ERP system for automatic aggregation after the check passes.

[0046] In this embodiment, the system hardware configuration includes: Structure Manager: Used to obtain the BOM structure and PBOM structure relationships through the BOM process maintenance integration port, clearly displaying the product's structure tree, including component types, BOM hierarchy relationships, process assembly information, BOM quantity, production storage location, etc.

[0047] Structure Reader: Used to read the entire product's PBOM, as well as updated BOM information and process assembly information after PBOM changes, and to verify the product's component attributes. The structure is read up to the first level of the virtual hierarchy; when traversing self-made parts and outsourced components, the BOM hierarchy is not expanded.

[0048] Type Attribute Manager: Constrains and manages the component types in PBOM that are virtual components, self-made components, and outsourced components, and constrains and creates fixed operations, changeover operations, and variable operations values ​​in component attributes.

[0049] Component Process Retrieval Tool: Used to input process retrieval information and retrieve the corresponding process value from component attributes and BOM based on the retrieval information. The built-in search engine supports fuzzy search and keyword matching search, and can perform functions such as retrieval of assigned processes, unassigned processes, and retrieval by process value.

[0050] Structure Editor: Used for maintaining and revising process assembly information in the PBOM. It edits the processes of components with empty processes in the BOM based on process retrieval information. The system performs batch selection of components and performs batch maintenance quickly and accurately based on the selected components. After batch maintenance, the process number is updated to the corresponding process field value.
