[0076] Before describing the implementation of the present invention in detail, it should be made clear that this patent provides a method and device for generating a process route based on a design BOM (process management platform), which aims to optimize the process route planning process from product design to production through automated means, improve production efficiency, reduce production costs, and ensure product quality. The following is a detailed description of the implementation of the present invention in conjunction with the accompanying drawings.

[0077] Data preparation

[0078] The data preparation stage is the cornerstone of the entire process routing process, which ensures the completeness and accuracy of the data required for subsequent steps.

[0079] Receiving CAD drawings: After completing product design, the product design department will generate electronic engineering drawings through the CAD system. These drawings contain detailed information such as the product's three-dimensional structure, component composition, and mutual assembly relationship, and are an important basis for process route planning. These drawing files are received through a preset standardized interface to ensure that the data is complete and accurate during the transmission process. The requirements of the standardized interface are highly compatible with the CAD system used by the product design department, and can seamlessly connect drawing files of various formats (such as DWG, etc.). At the same time, the interface can verify the data and conduct a preliminary check on the received drawings to ensure their completeness and accuracy.

[0080] Establish and maintain the process database: The process database is also an important component. It stores detailed information such as the processing steps, required tools, equipment, and process parameters of various parts. These data are the basis for process route planning and directly affect the accuracy and efficiency of subsequent steps. When establishing the process database, a modular design concept is adopted to classify different types of parts according to processing characteristics, and establish an independent database module for each type of part. Each module contains all the processing information of this type of parts, which is convenient for the system to quickly retrieve and match. In addition, a data update mechanism is designed to ensure that the process database can be continuously updated with the development of production practice. When new processing technologies, tools, or equipment appear, the system can automatically or manually add this information to the database to maintain its timeliness and accuracy.

[0081] Data extraction

[0082] After the data preparation phase is completed, the data extraction phase begins. This phase mainly involves extracting key information from CAD drawings.

[0083] CAD drawing parsing: The present invention uses professional CAD drawing parsing technology, which can extract key information such as part numbers, specifications, material properties, etc. from drawing files in DWG format. During the parsing process, the system will parse the drawings layer by layer, extract two-dimensional drawing information from the three-dimensional model, and convert it into a format that the system can recognize. In order to ensure the accuracy and efficiency of the analysis, the present invention optimizes the parsing algorithm. The algorithm can automatically identify key elements such as annotation information, dimension information, and assembly relationships in the drawings, and match them with preset templates. Through template matching, the system can quickly and accurately extract the required information.

[0084] BOM Generation

[0085] After extracting key information, the design BOM is automatically built based on this information.

[0086] Design BOM construction: Design BOM is a form of expression of product structure, which lists in detail all parts required for the product and their quantity, specifications, materials and other information. At the same time, the design BOM also contains the assembly relationship between parts, which provides an important basis for subsequent process route planning. When constructing the design BOM, a tree structure is used to represent the product structure. Each part is regarded as a node in the tree, and the assembly relationship between nodes is represented by the parent-child relationship. In this way, the system can clearly display the overall structure of the product and the relationship between the various components. In addition, the present invention also generates an expanded relationship table of the product structure tree. The table lists in detail all sub-parts of each part and their quantity, specifications and other information, which is convenient for data analysis and processing in subsequent steps.

[0087] Preliminary planning of process route

[0088] After the design BOM is completed, the preliminary process route planning phase begins. This phase mainly involves preliminary process route planning based on the design BOM and process database.

[0089] Intelligent matching algorithm: An intelligent matching algorithm is used to assign appropriate processing procedures to each part. The algorithm first searches for matching processing procedures in the process database based on the processing characteristics of the part (such as material, size, precision requirements, etc.). Then, the algorithm comprehensively considers multiple factors such as the availability of equipment resources (such as equipment type, processing capacity, etc.) and production rhythm (such as production cycle, production capacity requirements, etc.), and preliminarily plans a reasonable processing route for each part. The core of the intelligent matching algorithm lies in its comprehensive evaluation capability. The algorithm can consider multiple factors at the same time, and assign weights and prioritize these factors. Through comprehensive evaluation, the algorithm can select the optimal processing plan to ensure that the generated process route meets production requirements and has high execution efficiency.

[0090] Preliminary process route generation: Based on the intelligent matching algorithm, a preliminary process route is automatically generated. The process route lists in detail the processing steps, required tools, equipment, process parameters and other information for each part, and clarifies the sequence and flow relationship between each step.

[0091] The generation of the preliminary process route is an iterative process. The system will continuously adjust and optimize the process route according to the results of the intelligent matching algorithm until all production requirements are met. During the iteration process, the system will conduct a detailed evaluation and analysis of each step to ensure its rationality and feasibility.

[0092] Process route optimization

[0093] In order to cope with the complex and ever-changing production environment and ensure that the process route is both efficient and meets the actual production needs, the present invention innovatively introduces a process route optimization module. As the core component of the entire process planning system, this module undertakes the important task of in-depth analysis and optimization of the initially generated process route.

[0094] In-depth analysis: The optimization module will first conduct a comprehensive in-depth analysis of the preliminary process route. This step is not just a simple review of the process steps, but a comprehensive consideration of multi-dimensional factors such as product characteristics, production requirements, and equipment resources. Specifically, the system will evaluate the adaptability of the process route based on the physical characteristics of the product, such as material, size, and shape, as well as customer requirements for product quality and delivery time. At the same time, the system will also obtain real-time status information of equipment resources, including equipment availability, load conditions, maintenance plans, etc., to provide data support for subsequent optimization decisions.

[0095] Optimization strategy: Based on the in-depth analysis, the optimization module will use a variety of strategies to optimize the process route. The following are several main optimization strategies:

[0096] Adjust process sequence: By analyzing the logical relationship and time dependency between processes, the system can identify potential bottlenecks and links with long waiting times. By adjusting the process sequence, the system can reduce unnecessary waiting time and improve the smoothness and overall efficiency of the production line. For example, processes that can be processed in parallel can be merged or adjusted in order to reduce equipment idle time.

[0097] Select the optimal process parameters: For each process, the system will retrieve multiple feasible process parameter combinations from the process database based on product characteristics and equipment capabilities. Subsequently, the system will evaluate and compare these parameter combinations through simulation or historical data analysis, and select the optimal parameter combination that can both ensure processing quality and improve production efficiency.

[0098] Consider equipment load balance: In order to avoid excessive concentration or idleness of equipment resources, the system will monitor and predict equipment load in real time. By adjusting the equipment allocation and processing sequence in the process route, the system can ensure that the load between each device remains relatively balanced, thereby improving the stability and efficiency of the entire production line.

[0099] Output optimization results: After the above optimization steps, the system can output a more reasonable and efficient process route. The optimized process route not only reduces waiting time and production cycle, but also improves processing quality and production efficiency. At the same time, the system will also record and organize the key information and decision-making basis in the optimization process for subsequent analysis and reference.

[0100] Verification and output

[0101] After the process route optimization is completed, strict verification and testing links are set up to ensure that the optimized process route can run smoothly in actual production and achieve the expected results.

[0102] Verification process: The verification process covers multiple aspects such as the rationality of process steps, the availability of equipment resources, and the accuracy of process parameters. First, the system will perform a logical verification on the optimized process route to ensure that the sequence and logical relationship between the processes are correct. Secondly, the system will test run the process route in a simulated production environment through simulation and other methods to evaluate its adaptability and stability under different production conditions. Finally, if conditions permit, actual trial production can be carried out to further verify the feasibility and effectiveness of the process route through feedback from real production data.

[0103] After the output standard process file is verified, the system will output the optimized process route as a standard process file (such as PDF format). These files record in detail the key information such as the operating steps, required equipment, process parameters, precautions, etc. of each process, and present them to the production department in a clear and easy-to-read manner. The production department can directly use these files as production instructions for production preparation and actual operation. This not only simplifies the production preparation process, but also reduces the production risks caused by human errors. At the same time, standardized process documents also help to achieve traceability and quality control of the production process.
