Description

Technical Field

[0001] The present application relates to the technical field of automobile production and manufacturing, and particularly relates to a method, device and equipment for constructing a process assembly data model based on PBOM. Background Art

[0002] During the actual production process of the vehicle factory, in order to meet the requirements of the production rhythm, each process will carry out process planning according to the production line layout of each workshop, arrange sub-assembly processes, and build process assemblies based on the actual completed products of the sub-assembly processes.

[0003] Process assemblies are usually produced in a storage-based manner on the sub-assembly line, and then, together with other assembly parts, are sorted by the warehouse and sent to the main line for assembly along with the main line. In the traditional mode, process assemblies are managed manually offline. The sub-parts under the assembly pull materials one day in advance of the main line plan after the plan is generated for storage production, resulting in a large amount of inventory. At the same time, there is no indication for the assembly, and the operator delivers materials according to his own experience, which is prone to delivering the wrong parts and causing misassembly.

Due to the different layouts of the sub-assembly processes in the workshops, the requirements for process assemblies in the workshops are different.

[0045] MES: Manufacturing Execution System.

[0046] To make the purpose, technical solutions and advantages of this application clearer, the following will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0047] In a first aspect, an embodiment of this application provides a method for constructing a process sub-assembly data model based on PBOM.

[0048] In one embodiment, refer to Figure 1 , Figure 1 , which is a schematic flow chart of the method for constructing a process sub-assembly data model based on PBOM in this application. As Figure 1 shown, the method for constructing a process sub-assembly data model based on PBOM includes:

[0049] S1: Create a sub-assembly template in the PBOM system, and when creating the sub-assembly template, establish the vehicle model corresponding to the process sub-assembly and the delivery station corresponding to the process sub-assembly;

[0050] In this application, the sub-assembly template includes the process sub-assembly group code, the name of the process sub-assembly, the status of the process sub-assembly, the vehicle model or assembly corresponding to the process sub-assembly, the manufacturing route, the assembly route, and the delivery station corresponding to the process sub-assembly. For the delivery station, it includes the primary delivery station and the secondary delivery station. The primary delivery station is the primary delivery station of the sub-assembly area where the process sub-assembly belongs, and the secondary delivery station is the final assembly station of the process sub-assembly.

[0051] That is, first create a sub-assembly template in the PBOM system. The process sub-assembly code in the sub-assembly template is the process sub-assembly group code. When creating the sub-assembly template, it is necessary to establish the vehicle model corresponding to the process sub-assembly, as well as the primary delivery station and the secondary delivery station corresponding to the process sub-assembly, so as to realize the reconstruction of PBOM data according to the production line layout and the process to which it belongs.

[0052] Further, in one embodiment, after the sub - assembly combined part template is created, it further includes:

[0053] S101: According to the delivery workstations to which the process combined parts defined by the sub - assembly combined part template belong, the PBOM system hangs the grouped codes of the process combined parts under the workstation layout of the corresponding production line, and reconstructs the workstation layout of the production line;

[0054] S102: Classify the process combined parts by type, define the same grouped codes for the same process combined parts, and realize the standardization of the classification of process combined parts;

[0055] S103: Define the vehicle models or assemblies to which each process combined part classification belongs, so as to generate the data hierarchy of process combined parts according to vehicle models or assemblies. That is, define which vehicle model or assembly's lower - level the process combined part classification belongs to, which is convenient for automatically generating the data hierarchy of process combined parts according to vehicle models or assemblies.

[0056] S2: Classify the grouped codes of the process combined parts of the same vehicle model or assembly, convert the vehicle model number or assembly and the grouped codes of the process combined parts into the parent combined part number, and define the parts with the same grouped codes of the process combined parts as sub - part items under the parent combined part number;

[0057] Specifically, for the automatic generation logic of process combined parts: when expanding the data of the vehicle model number or assembly, classify the grouped codes of the process combined parts of the same vehicle model or assembly, and automatically convert the vehicle model number or assembly + the grouped codes of the process combined parts into the parent combined part number, and define the parts with the same grouped codes of the process combined parts as sub - part items under the parent combined part number.

[0058] Further, after defining the parts with the same grouped codes of the process combined parts as sub - part items under the parent combined part number, it further includes: regarding the process combined parts as the lower - level of the corresponding vehicle model or assembly, and reusing the corresponding relationship between the process combined parts and the delivery workstations as the logistics distribution attribute of the process combined parts.

[0059] S3: Based on the classification of the process combined parts, construct the grouped codes of the process combined parts to associate the grouped codes of the process combined parts with the corresponding production line;

[0060] Specifically, define the classification of the process combined parts, construct the standard grouped codes of the process combined parts, add the grouped codes of the process combined parts and the process layout (factory, workshop, production line, workstation), so as to associate the grouped parts of the process combined parts with different production lines.

[0061] It should be noted that the sub - assembly combined part template corresponds to the production line layout and route according to the vehicle model assembly it belongs to; the sub - assembly combined part template is established according to the production process of the production line; the sub - assembly combined part template needs to select the primary distribution station of the process combined part sub - parts and the secondary distribution station of the process combined part according to the production line layout; it supports the creation, modification, and deletion of the sub - assembly combined part template; it supports different production lines corresponding to the same process combined part code; the same process combined part code has only one unique primary distribution station under the same production line layout; the sub - assembly combined part template takes effect immediately after creation; after the sub - assembly combined part template is created, the process combined part grouping code is automatically displayed under the station layout structure tree of the corresponding production line, and the secondary distribution station where the process combined part is located is displayed under the process combined part grouping code.

[0062] S4: Based on the BOM data of the vehicle model or assembly, define the process layout of the production line and the process combined part grouping code on the parts of the BOM data. That is, based on the expanded BOM data of the vehicle model or assembly, define the defined production line process layout (factory, workshop, production line, station) and the process combined part grouping code on the parts of the BOM data.

[0063] In this application, based on the BOM data of the vehicle model or assembly, define the process layout of the production line and the process combined part grouping code on the parts of the BOM data. Among them, for defining the process layout of the production line and the process combined part grouping code on the parts of the BOM data, it specifically includes: building the process combined part structure in the PBOM system and automatically generating the process combined part structure in the PBOM system.

[0064] Specifically, for building the process combined part structure in the PBOM system, it specifically includes:

[0065] S401: Through the definition of the distribution station, define the distribution station of the sub - parts to which the process combined part belongs and the process combined part grouping code to generate the process combined part structure tree; that is, define the primary distribution station of the sub - parts to which the process combined part belongs and the process combined part grouping code to generate the process combined part structure tree;

[0066] S402: Based on the distribution station of the process combined part, realize the on - site logistics distribution of the process combined part; that is, define the secondary distribution station of the process combined part to realize the on - site logistics distribution of the process combined part;

[0067] S403: Select the vehicle model and the production line corresponding to the vehicle model in the PBOM system, according to the distribution station information and the process combined part grouping code composition information in the vehicle model;

[0068] S404: Extract the station information and the process combined part grouping code under the production line layout corresponding to a single vehicle model in the PBOM system, statistically summarize the process combined part grouping codes to which the sub - parts in the PBOM system belong, and define the sub - parts hanging under the same process combined part grouping code as the same process combined part to build the process combined part structure tree.

[0069] Specifically, for the automatic generation of the process assembly structure in the PBOM system, it specifically includes: according to the constructed process assembly structure tree and in accordance with the generation logic of the process assembly, generating the process assembly data structure and the distribution station attributes, and realizing the automatic generation of the process assembly structure in the PBOM system.

[0070] For the sub-assembly part number, it is the vehicle model number or the assembly number + the process assembly grouping code; for the process assembly structure logic: when the vehicle model number or the planned assembly number is the parent item, the sub-assembly part number is the child item, and the parts with the same defined process assembly grouping code are the lower-level sub-parts of this sub-assembly part number. The first distribution station and the second distribution station are the shared logistics attributes of the process assembly and the sub-parts.

[0071] It should be noted that when defining the distribution station, define the distribution station of the sub-parts under the process assembly structure to the second distribution station under the process assembly grouping code, and automatically calculate and hang the selected sub-parts to the first distribution station where the process assembly grouping code is located; when the distribution station definition is completed and the station notice is released, the operation logic of the process assembly structure tree takes effect; the operation logic of the process assembly structure tree: the sub-parts under the same process assembly grouping code hooked under the same production line of the same vehicle model constitute the process assembly structure tree under this process assembly grouping code; in the PBOM system, select a single vehicle model and the production line corresponding to the vehicle model, and the process assembly structure tree can be calculated according to the process assembly structure tree logic to generate the process assembly structure of the instantiated vehicle model on this production line.

[0072] Furthermore, when the production system is N + 6, make a production data request, send a request to the PBOM system to extract the vehicle model. The PBOM system automatically generates the process assembly structure and data entities according to the requested vehicle model or assembly, and performs real-time calculation to generate the process assembly, so as to produce the entity process assembly related to the vehicle model plan. After the production system receives the entity process assembly, expand the logistics attributes and plan attributes of the current process assembly. The production system realizes integration based on the logistics attributes such as the online method expanded by the process assembly grouping code.

[0073] The MES system sends the plan to the PBOM. The PBOM interface selects the vehicle model according to the plan requirements, and finds the instance vehicles included according to the selected vehicle model or assembly; sequentially obtains the manufacturing structure according to the instance product code and maturity (ready, nearly completed, put into production); obtains all the process structures that define the process assembly grouping code according to the manufacturing structure; the applicable vehicle model of the process structure matches the current selected instance vehicle, and queries the most suitable process structure of each manufacturing structure under different lines (instance vehicle > basic vehicle > vehicle series > undefined applicable vehicle model); queries the sub-assembly part number corresponding to the process assembly grouping code and matches the structure.

[0074] In this application, by creating a grouped coding for process sub-assemblies in the PBOM system, the production line layout is reconstructed based on the first distribution workstations of the grouped coding for process sub-assemblies, and the PBOM data is reconstructed based on the second distribution workstations of the process sub-assemblies maintained according to the production line layout, and the structural data of the process sub-assemblies is built in the PBOM.

[0075] The PBOM system interface is connected to the production plan of the MES system. The PBOM interface extracts in real time the instantiated vehicle model, the BOM date of the vehicle model, and the relevant information of the production line where the vehicle model is located from the production plan. According to the information such as the BOM date of the instantiated vehicle model and the production line where it is located, the data structure of the instantiated vehicle model is calculated to generate the grouped coding for process sub-assemblies and the process sub-assembly structure tree of the instantiated vehicle model, guiding the flexible production of factory products. The MES system generates the sub-assembly plan for process sub-assemblies and the completion statistics of process sub-assemblies.

[0076] The factory realizes real-time pulling of sub-assembled parts according to the sub-assembly plan for process sub-assemblies, reduces redundant sub-assembly inventory, and halves the factory inventory. The factory accurately controls the sub-assembly rhythm according to the completion statistics of process sub-assemblies to improve the saturation of sub-assembly operations. The logistics department of the factory accurately distributes the process sub-assemblies according to the process sub-assembly structure tree, accurately indicates on-site operations, reduces the misassembly rate of parts, and reduces rework.

[0077] The method for constructing a process sub-assembly data model based on PBOM in the embodiment of this application, by constructing a template structure for sub-assembled parts in the PBOM system, can generate a sub-assembly plan for process sub-assemblies, can perform real-time pulling of a single vehicle according to the sub-assembly plan for process sub-assemblies and produce sub-assembled parts, reducing the redundant inventory in the factory; according to the sub-assembly plan for process sub-assemblies, the completion statistics of process sub-assembly parts can be carried out, accurately controlling the sub-assembly rhythm to improve the saturation of factory operations; according to the process sub-assembly structure tree, accurate distribution of process sub-assemblies can be realized, accurately indicating on-site operations, reducing the misassembly rate of parts, and reducing rework.

As Figure 2 shown, the device for constructing a process sub-assembly data model based on PBOM includes: a creation module, a definition module, an association module, and an execution module.

[0080] The creation module is used to create a sub - assembly combined part template in the PBOM system, and when creating the sub - assembly combined part template, the corresponding vehicle model and the corresponding distribution station of the process combined part are established; the definition module is used to classify the process combined parts with the same vehicle model or assembly by group coding, so as to convert the vehicle model number or assembly and the process combined part group coding into a parent combined part number, and define the parts with the same process combined part group coding as sub - item parts under the parent combined part number; the association module is used to construct a process combined part group coding based on the classification of the process combined parts, so as to associate the process combined part group coding with the corresponding production line; the execution module is used to define the process layout of the production line and the process combined part group coding on the parts of the BOM data based on the BOM data of the vehicle model or assembly.
