Description

Technical Field

[0001] The present invention relates to the field of tires, and in particular to a tire design drawing expansion and PLM integration method, device, medium and program. Background Art

[0002] In the tire product series drawing development project with the same design rules, the drawing design is generally divided into two stages: the first stage is the design and development of the first specification drawing, and the second stage is the same series expansion of the multi-specification drawing design. That is, after the design and development of the first specification drawing is completed, the subsequent multi-specification drawing design can be parameterized according to the design rules to make the series design of the same design rules more regular and standardized. In conventional design, the project leader usually performs parameter design of all specifications after the first specification drawing design is completed, and then distributes it to the specification leaders of the project team to develop the drawing design.

[0003] The Chinese invention patent application (publication number CN112182259A, publication date: 20210105) discloses a drawing parameter processing method and device, including: parsing the target drawing to obtain drawing parameter information; comparing the drawing parameter information with the material attribute information in the PLM system to obtain a comparison result; and associating and synchronizing the drawing parameter information with the material attribute information based on the comparison result. This application helps to ensure the consistency of the material parameters in the drawing and the general library of the PLM system, and improve the maintenance efficiency and accuracy of the material parameters.

[0004] The existing technology has the following deficiencies: First, the summary and use of all design parameters usually use tables and other files and documents to save data, and use manual extraction for secondary use. Not only is it inefficient, but once the design parameters of a certain specification cannot meet the actual drawing design, it is necessary to feedback data upward. It is difficult to ensure the immediacy of data transmission, resulting in database parameter errors caused by the project leader's failure to update the design parameters in time, that is, the parameter design summary table is inconsistent with the actual design parameters. Second, each specification manager develops drawings separately, and all drawing files are saved on their own computers, which will lead to the problem of scattered drawings and poor security. Even if the summary is performed through file transfer, once a certain specification design drawing is changed, it is difficult to ensure the consistency of personal design data and summary data, resulting in mold processing errors. Third, each specification manager develops drawings separately. During the mold processing stage, it is easy to submit repeated parts processing for mold parts that are exactly the same in the same series development, which increases the confirmation time in the early stage of mold development, thereby lengthening the mold development cycle. As a result, the three problems caused by the method of having the project responsible person carry out parameter design and distributing it to the project team's specification managers to design tire product drawings have made conventional designs have obvious limitations and defects. It is impossible to efficiently design and produce drawings, unify drawing file management, and process mold parts while ensuring that the data source is accurate and unique. Summary of the invention

[0005] The purpose of the present invention is: to address the above problems, a tire design drawing expansion and PLM integration method, device, medium and program are proposed, which is to design a digital model structure of a tire product in a CATIA environment and define the attributes of nodes at all levels; automatically extract the relationships, attributes and parameters in the digital model structure in combination with CATIA secondary development, use a program to automatically replace the configuration line to drive the product digital model to perform automated series expansion, and integrate PLM to automatically number and write back the nodes at all levels, and finally complete the automated series expansion of the design drawings and the automatic preservation of the digital parts and drawings in the PLM system.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0008] 1) According to the product design, complete the construction of the digital model structure diagram of tire product design in the CAITA environment;

[0009] 2) Coding object design: The parameters and components at all levels in the digital model structure are taken as coding objects and designed and created;

[0010] 3) Combine CAITA secondary development and PLM integration to complete the local storage of digital models / drawings with automatic series expansion and automatic numbering of product design drawings;

[0011] 4) CATIA integrated with PLM, using CATIA secondary development to upload and save tire product design related information to the PLM system to complete the tire design drawing series expansion and PLM integration process.

[0012] Preferably, in step 1), the design parameters are classified and defined and a configuration table is created, parameters are created and associated relationships are established in the CAITA environment, the product design drawing assembly structure is built, and a combination of template calling or self-creation is used to create components and sub-components at all levels, and the upstream data release is used as the downstream design input to complete the construction of the digital model structure diagram of the tire product design with upper and lower associated designs.

[0013] Preferably, in step 2), when designing and creating the parameters in the digital model structure as coding objects, all parameters in the assembly structure are classified, and the parameter objects that do not participate in the coding are placed in the "_UNTEAD_" parameter set of the "parameters" of the digital model structure tree, and the parameter objects that participate in the coding are directly placed under the "parameters" of the digital model structure.

[0014] Preferably, in step 2), when designing and creating components at all levels in the digital model structure as coding objects, "attributes" are created for all hierarchical components in the digital model structure (including Code (part number)) for program extraction, thereby completing the digital model coding structure of the tire product design drawing.

[0016] 3.1) For the case where there is only a one-to-many relationship between the Sidewall_STB configuration table (active block configuration table, where there are multiple product configuration rows for the same SIZE) and SIZE, CATIA secondary development is used to pair the configuration rows of the Size in the STB configuration table that is the same as the current Profile configuration row, i.e., a Size configuration row in the Profile corresponds to a configuration row group of the same Size in the Sidewall_STB configuration table;

[0017] 3.2) Start the CATIA secondary development program to automatically expand the product of the configuration line successfully matched in step 3.1) and update the digital model assembly;

[0018] 3.3) After each update of a product configuration drawing is completed, the assembly structure object of the product design drawing is automatically extracted to generate a coded temporary file; the extracted content includes the assembly structure hierarchy, the instance name, part number, parameters and attributes of each level node; one configuration line corresponds to one product design, and a coded temporary file is generated;

[0019] 3.4) CATIA integrates with the PLM system, and uses the CATIA secondary development program to submit the data objects in the temporary coding file in step 3.3) to the PLM system, encodes the parts at each level according to the coding rules, and returns the part codes at each level to the CATIA end, that is, writes the codes back into the temporary coding file, and generates a coding transfer file;

[0020] 3.5) CATIA secondary development program automatically writes the part codes of each level in the coding transfer file in 3.4 above back to the attribute "Code" of the product design digital model structure; at the same time, the necessary digital models and drawings of each level of assembly are saved locally with the part code as the file name;

[0021] 3.6) Repeat the above steps 3.2) - 3.5). After the digital model / drawing of the product design of the currently updated configuration row is successfully saved locally, the program automatically updates the next row of product configuration until all the configuration rows successfully paired in step 3.1) are expanded.

[0024] 3.2.2) Select the product extension instantiation drawing type: select CATDrawing or dwg type, or both types;

[0025] 3.2.3) Select the product expansion type: Check Auto Expansion for fully automatic expansion, uncheck it to expand only one configuration line product. After completion, you need to manually start the expansion of the next configuration line product. In the full assembly, the configuration line group of a Sidewall_STB (all STB configuration lines corresponding to the same Size as the Profile) must be fully expanded before the configuration line group corresponding to the next Size can be expanded.

Create parameters and establish associations in the CAITA environment, build the assembly structure of the product design drawing, and use a combination of template calling or self-creation to create components and subcomponents at all levels. Use upstream data publishing as downstream design input to complete the construction of the digital model structure diagram of the tire product design with upper and lower association designs. In this way, the full assembly design drawing can be automatically updated when the Profile product configuration line is changed.

[0044] 2) Coding object design:

[0045] 2.1) Design and create parameters in the digital model structure as coding objects: classify all parameters in the assembly structure, put parameter objects that do not participate in coding into the "_UNTEAD_" parameter set of the "Parameters" in the digital model structure tree, and put parameter objects that participate in coding directly into the "Parameters" of the digital model structure.

[0046] 2.2) Design and create components at all levels in the digital model structure as coded objects: Create "attributes" such as Code (part number) for all levels of components in the digital model structure for program extraction (such as Figure 3 As shown). This completes the digital model coding structure of the tire product design drawing (as shown Figure 4 , Figure 5 ).

[0047] 3) Combined with CAITA secondary development and PLM integration, complete the local storage of digital models / drawings with automatic series expansion and automatic numbering of product design drawings:

[0048] 3.1) For the Sidewall_STB configuration table (active block configuration table, there will be multiple product configuration rows with the same SIZE) that has a one-to-many relationship with SIZE (such as Figure 6), using CATIA secondary development, pair the configuration rows in the STB configuration table with the same Size as the current Profile configuration row, that is, form a configuration row group with the same Size in the Sidewall_STB configuration table corresponding to one Size configuration row in the Profile.

[0049] 3.2) Start the CATIA secondary development program to automatically expand the configuration line successfully matched in step 3.1) and update the digital model assembly:

[0051] 3.2.2) Select the product extension instantiation drawing type: select CATDrawing or dwg type, or both types;

[0052] 3.2.3) Select the product expansion type: Check Auto Expansion for fully automatic expansion, uncheck it for the program to only expand one configuration line product, and after completion you need to manually start the expansion of the next configuration line product (such as Figure 7 ); In the full assembly, the configuration line group of a Sidewall_STB (all STB configuration lines corresponding to the same Size as the Profile) must be fully expanded before the configuration line group corresponding to the next Size can be expanded.

[0053] 3.3) After each update of a product configuration drawing is completed, the assembly structure object of the product design drawing is automatically extracted to generate a coded temporary file; the extracted content includes the assembly structure hierarchy, the instance name, part number, parameters and attributes of each level node; one configuration line corresponds to one product design, and a coded temporary file is generated;

[0054] 3.4) CATIA integrates with the PLM system, and uses the CATIA secondary development program to submit the data objects in the temporary coding file in step 3.3) to the PLM system, encodes the parts at each level according to the coding rules, and returns the part codes at each level to the CATIA end, that is, writes the codes back into the temporary coding file, and generates a coding transfer file (such as Figure 8 );

[0055] 3.5) CATIA secondary development program automatically writes the part codes of each level in the coding transfer file in 3.4 above back to the attribute "Code" of the product design digital model structure; at the same time, the necessary digital models and drawings of each level of assembly are saved locally with the part code as the file name;

[0056] 3.6) Repeat the above steps 3.2) - 3.5). After the digital model / drawing of the product design of the currently updated configuration row is successfully saved locally, the program automatically updates the next row of product configuration until all the configuration rows successfully paired in step 3.1) are expanded.

[0057] 4) CATIA integrates PLM, and uses CATIA secondary development to upload and save tire product design related information to the PLM system to complete the tire design drawing series expansion and PLM integration process. The uploaded content includes digital model parts, drawings, product part assembly structure and design parameters saved locally. This solves the problem of scattered storage and poor security caused by the design drawings being saved locally by the design engineer. The part / drawing information saved by PLM contains parameter information to meet the query and reuse of assembly design.

[0058] The present invention drives the expansion of product design drawing series through associative design through rules and formulas, combines CATIA secondary development, and integrates PLM program development, and finally completes the automatic numbering and storage of digital model parts and drawings in PLM; utilizes program development to extract and apply the relationships, parameters, attributes, etc. in the digital model, thereby realizing the automatic expansion and system preservation of tire product design drawings; the method can effectively improve the efficiency of tire design drawing series expansion, realize the automatic database preservation of drawing files containing data relationships in the PLM system, and at the same time improve the drawing assembly accuracy, so as to be used for tire drawing design and version management.
