Description

[0001] The present application relates to the technical field of vehicles, and in particular, to a method for processing vehicle virtual assembly processes and related devices. Background Art

[0002] With the development of computer technology, vehicle virtual assembly technology, which combines computer technology with vehicle assembly processes, has also made great progress, covering multiple vehicle production and development steps such as product research and development, process testing, process verification, and guiding assembly.

[0003] In the vehicle virtual assembly process flow in related technologies, a linear information transfer mode is mostly adopted. That is, after the data is released from the R & D end, the virtual assembly end conducts data verification, and then the virtual assembly end publishes the problems detected during data verification to the pre-manufacturing end. Finally, the pre-manufacturing end transfers the received problems to the on-site manufacturing end. Conversely, the problems that occur at the on-site manufacturing end are also fed back to the R & D end in the above process in sequence.

[0004] However, due to the long information transfer chain in the process flow of the linear information transfer mode, real-time information sharing and interconnection cannot be achieved, resulting in low information transfer efficiency between departments and reducing the development efficiency and development ability of the assembly process flow.

[0052] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0053] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances, which is only a way of distinguishing objects with the same attributes when describing the embodiments of the present application.

[0054] At present, the in-vehicle assembly on the vehicle manufacturing assembly line follows a one-dimensional linear information transfer mode. For example, the vehicle assembly data obtained by the R & D department is sent to the virtual assembly engineer for verification. After the verification is completed, the virtual assembly engineer publishes the problems found in the verification to the early-stage manufacturing engineer (ME). The ME then transfers the information to the assembly site to guide vehicle assembly. When vehicle assembly problems are found at the assembly site, they are also fed back to the R & D department level by level through the ME and the virtual assembly engineer in the same way.

[0055] This way of transferring information level by level has low information transfer efficiency and is difficult to bring into play the synergy effect of each department. Due to the long feedback chain of information transfer, the R & D department cannot quickly and effectively obtain process feedback information, and the on-site assembly department cannot quickly obtain the assembly solutions given by the front-end based on the reported vehicle assembly problems.

[0056] Therefore, the embodiment of this application proposes a vehicle virtual assembly process processing method. Based on digital intelligent manufacturing, through the collaborative development and management of parts and assembly processes, it realizes the interconnection and collaborative operation of the vehicle's overall vehicle design and assembly process, and improves the assembly quality and efficiency of the vehicle.

[0057] For the convenience of description, next, based on a vehicle virtual assembly process management system, the vehicle virtual assembly process processing method provided by the embodiment of this application will be described. At this time, the vehicle virtual assembly process processing system includes a manufacturing requirements (MR) processing module for parts assembly design guidance standards, a bill of process (BOP) processing module for parts assembly processes, and a closed-loop processing module for the assembly problem list. These three modules operate in coordination to form a processing system to implement the assembly process processing method provided by this application.

[0058] Please refer to Figure 1 , Figure 1 , which is a flowchart of a vehicle virtual assembly process processing method provided by the embodiment of this application. The method includes S101 - S104:

[0059] S101: Generate the parts assembly process flow of the vehicle to be assembled according to the pre-saved vehicle part-level virtual assembly design requirement database. The parts assembly process flow is used to identify the part development and design requirements in the management process.

[0060] The system described above. This step is mainly implemented by the MR module. Among them, the part assembly data for generating the part assembly process flow can be stored in the MR module in the form of a standard library, that is, stored in the vehicle part-level virtual assembly design requirement database. This vehicle part-level virtual assembly design requirement database belongs to the part-level standard library for vehicle design and assembly, and may include parts such as the body, chassis, vehicle interior and exterior, vehicle electronic and electrical appliances, and vehicle three-electric systems.

[0061] At this time, the part assembly data stored in the vehicle part-level virtual assembly design requirement database also includes the assembly method, assembly requirements, and verification method of each part, so as to facilitate the generation of inspection checklists and inspection task management for specific projects based on this standard library.

[0062] In some possible implementation manners of the embodiments of the present application, in this standard library, for each part, based on the historical assembly process of each part, it also includes the historical project assembly problems of each part, the analysis of competing vehicles of the same part, the visual information of on-site assembly, and the newly developed process plan to guide the development of new product vehicles.

[0063] After that, based on the part information saved in the standard library, a list is generated for the assembly processes of different parts. This list includes the part assembly design requirement management process for each part of the vehicle to be assembled, so as to guide the on-site assembly end to perform assembly based on this list.

[0064] In some other possible implementation manners of the embodiments of the present application, the generated part assembly process flow may include the peripheral environment data number and its screenshot of the previous assembled vehicle, and at the same time, visual information such as videos is attached to the part assembly to facilitate guiding the part assembly.

[0065] In this way, traces can be left in the inspection process, and at the same time, the effectiveness of the inspection content can be evaluated, and the problem feedback and problem-solving progress can be shared to achieve the whole-process control of the manufacturing requirements inspection.

[0066] In a possible implementation manner, S101 includes:

[0067] S1011: Generate the part assembly processes of the multiple parts according to the part assembly data corresponding to the multiple parts in the vehicle part-level virtual assembly design requirement database;

[0068] S1012: Determine the part assembly process flow of the vehicle to be assembled according to the part assembly processes of the multiple parts.

[0069] Among them, the determined part assembly process flow can reflect the design requirement management of part assembly from the process.

[0070] S102: Generate the virtual assembly design management structure tree of the vehicle parts of the to-be-assembled vehicle according to the pre-built overall vehicle project structure tree.

[0071] For the system as described above, this step is mainly implemented by the BOP module. Among them, the BOP module pre-builds an assembly overall vehicle project structure tree, that is, the digital process library for factory general assembly. Specifically, an inherent process tree template is formed according to this process library, and based on this template, the assembly process file of the to-be-assembled vehicle is generated, so as to form the virtual assembly design management structure tree of the vehicle parts corresponding to the to-be-assembled vehicle.

[0072] In some possible implementation manners, the virtual assembly design management structure tree of the vehicle parts of a certain to-be-assembled vehicle can be exported through the correspondence between the key names of the parts and the project code numbers in the overall vehicle project structure tree in the Technical Capability Evaluation (TCE). At this time, similar to the overall vehicle project structure tree, the virtual assembly design management structure tree of the vehicle parts appears in the form of tree-shaped data, that is, the virtual assembly design management structure tree of the vehicle parts that identifies the overall vehicle assembly process flow is formed.

[0073] Compared with the method of manually building the overall vehicle process environment data and verifying it, this method can automatically export the overall vehicle assembly process file (the virtual assembly design management structure tree of the vehicle parts) for guiding the implementation of the assembly process, reduce the problem of low verification efficiency caused by data transfer lag and missed verification in manually building the model and verifying, strengthen the effectiveness of the process flow verification, reduce the cost brought by assembly process changes, and improve the development efficiency of the overall vehicle assembly and vehicle products.

[0074] In one possible implementation manner, the overall vehicle project structure tree is determined according to the design requirements of the multiple parts of the to-be-assembled vehicle and the assembly process flows respectively corresponding to the multiple parts.

[0075] It should be noted that the determination of the overall vehicle project structure tree is not limited to the parts included in a certain to-be-assembled vehicle, but also covers the parts of other types of to-be-assembled vehicles and the design requirements of the corresponding assembly process flows.

[0076] In one possible implementation manner, S102 includes:

[0077] S1021: Generate the overall vehicle factory general assembly process tree template according to the pre-built overall vehicle project structure tree;

[0078] S1022: Generate the assembly process flows corresponding to the multiple parts according to the overall vehicle factory general assembly process tree template and the part parameters respectively corresponding to the multiple parts of the to-be-assembled vehicle;

[0079] S1023: Generate a virtual assembly design management structure tree of the whole vehicle parts of the vehicle to be assembled according to the multiple assembly process flows.

[0080] Import the BOP module developed by TCE according to the general assembly process tree template of the whole vehicle factory included in the pre-built whole vehicle project structure tree, screen the existing vehicle models and configuration codes in the system, and automatically generate the assembly project structure tree of the general assembly process tree of the whole vehicle factory according to the template, and generate the general assembly process tree template of the whole vehicle factory, which can also be recorded as the general assembly process tree template of the whole vehicle factory.

[0081] According to the general assembly process tree template of the whole vehicle factory, automatically obtain multiple parts of the vehicle to be assembled in the whole vehicle project structure tree, and respectively automatically correspond them to the corresponding workstations; automatically export the whole vehicle assembly process flow of the corresponding vehicle model of the vehicle to be assembled, and guide the on-site process implementation based on the general assembly process of the whole vehicle assembly process.

[0082] S103: Determine the problem process flows in the part assembly process flow and the virtual assembly design management structure tree of the whole vehicle parts according to the part assembly process flow and the virtual assembly design management structure tree of the whole vehicle parts.

[0083] S104: Correct the problem process flow according to the correspondence between the problem process flow, the part assembly data corresponding to the part assembly process flow and the whole vehicle project structure tree.

[0084] For the system as described above, steps S103 and S104 are mainly implemented by the closed-loop processing module for the assembly problem list. Among them, the closed-loop processing module for the assembly problem list can extract the entries with assembly problems in the list given by the MR module, so as to form an online problem list, and then display, send, transfer, alarm and close the on-site problem list; for the assembly problems (problem process flows) with process conflicts or process optimization requirements in the BOP module, an online problem list can be formed to display, send, transfer, alarm and close the on-site process problems in a timely manner.

[0085] In some possible implementation manners of this embodiment, the closed-loop processing module for the assembly problem list can further identify the process flow problems that need to be supplemented in the list based on historical projects, such as virtual verification problems and on-site assembly problems, so as to realize the upgrade of the foregoing standard library. Furthermore, export the relevant process problem list according to the requirements of ME to realize the docking with ME.

[0086] Among them, the problem process flow can be marked and identified in the list exported by the MR module according to the feedback of the on-site assembly end based on the actual assembly process of the vehicle to be assembled.

[0087] In a possible implementation, S103 includes: determining the problem process flows in the part assembly process flow and the vehicle assembly process flow according to the part assembly process flow, the vehicle assembly process flow, and the problem process flows in the assembly history.

[0088] That is to say, according to the design requirements of the part assembly process flow, it is determined whether there are design problems with the part. According to the part assembly process flow and the vehicle assembly process flow, the problem process flows in the part assembly process flow and the vehicle assembly process flow are determined.

[0089] The determined part design problems and process problems are timely dispatched to the corresponding person in charge through the problem processing module for design or process optimization, so as to improve the development efficiency and the communication efficiency of problems, and enhance the product design quality.

[0090] Next, a practical scenario will be combined to introduce the specific working process of S101 step in the foregoing embodiment, that is, the specific working process of the MR module.

[0091] Please refer to Figure 2 , Figure 2 , which is a schematic diagram of a part-level MR assembly design guidance standard library provided by an embodiment of the present application. In this schematic diagram, for a certain part, the fixed inspection items of the part are generated according to the inspection catalog. Among them, the design requirements of the part assembly process flow include one or more of the part assembly sequence, the part assembly path, the part assembly tool space, the unification of part fasteners, the part assembly man-machine, the part total assembly line transportation equipment, the part integration strategy, the part assembly accuracy, the part assembly quality, and the part assembly efficiency.

[0092] In some possible implementations, the ten inspection items in the above part assembly process flow can be numbered. For example: MR01 corresponds to the design requirement of the part assembly sequence; MR02 corresponds to the design requirement of the part assembly path; MR03 corresponds to the design requirement of the part assembly tool space; MR04 corresponds to the requirement of the unification of part fasteners; MR05 corresponds to the design requirement of the part assembly man-machine; MR06 corresponds to the design requirement of the part tooling equipment; MR07 corresponds to the design requirement of the part integration strategy, MR08 corresponds to the part assembly accuracy requirement, MR09 corresponds to the part assembly quality requirement, and MR10 corresponds to the part assembly efficiency requirement. Furthermore, according to the department and the part number, it is numbered through "department + part name + MR", which is convenient for refining and decomposing the design requirements of each part, and is also convenient for accurately dispatching specific items to engineers for guiding the part assembly of the vehicle.

[0093] Specifically, for each part, there is an assembly design guidance standard corresponding to the above design requirements. At this time, the basic information of the part includes the number, version number, specific inspection item name, assembly requirements, verification method, graphical illustration, problem category, control method; inspection stage; historical project status; bid vehicle analysis; vehicle installation video link, vehicle classification and product structure (Vehicle Partitioning Product Structure, VPPS) corresponding to the vehicle structure tree, and fitment & function code (FFC) information.

[0094] Among them, the control method indicates the control source during the assembly of the part. For example, one part should be internally controlled by the part engineer, while another part needs to be controlled by the general layout engineer. There are also parts that need to be controlled by the virtual assembly engineer or the manufacturing engineer. The inspection stage determines at which stage of a vehicle to be assembled the part is inspected, such as the styling stage or the engineering data stage, etc.

[0095] Please refer to Figure 3 , Figure 3 , which is a partial schematic diagram of a part-level MR assembly design guidance standard library provided by an embodiment of the present application. In this partial schematic diagram, there is a template regarding the historical project status, including the status of historical project verification, problems in on-site manufacturing of historical projects, and the solutions at that time, the verification of the assembly number for the virtual verification status of the existing project, and the report link of relevant projects. It is convenient to search for the historical project status and trace the verification status.

[0096] Please refer to Figure 4 , Figure 4 , which is another partial schematic diagram of a part-level MR assembly design guidance standard library provided by an embodiment of the present application. In this partial schematic diagram, there is a template for bid vehicle analysis (such as the general assembly process tree template of the vehicle factory), and for each item in the design structure diagram of the bid vehicle model, it is presented in the form of an attachment, which is convenient for reference during design.

[0097] Next, taking the installation process of the high-voltage wire of an electric vehicle charging port as an example, in combination with the ten design requirements corresponding to the ten inspection items of MR01 - MR10 mentioned above, it will be further introduced with reference to the accompanying drawings.

[0098] MR01: Design requirement for part assembly sequence. During the design stage of the part, the installation logic of surrounding parts needs to be considered, and in combination with the on-site process layout, it is implemented in the part design. In the assembly of the high-voltage wire of the charging port and the small door of the charging port, the high-voltage wire of the charging port needs to be installed first, and then the small door of the charging port; otherwise, there will be a situation where the parts cannot be installed due to mutual exclusion.

[0099] MR02: Assembly path design requirements. Please refer to Figure 5 , Figure 5 Figure for the assembly path design in the installation of the high-voltage wire for the electric vehicle charging port. At this time, considering the surrounding environment of the part installation and its loading path, it is required to design a certain safety clearance with the surrounding wheelhouse sheet metal during the loading process to avoid interference in the installation path, which may affect the part quality or prevent the part from being installed completely.

[0100] MR03: Assembly tool space design requirements. Please refer to Figure 6 , Figure 6 Figure for the assembly tool space design requirements in the installation of the high-voltage wire for the electric vehicle charging port. Considering the installation torque of the part, select the corresponding tool gun. The MR entry will provide the digital model of the corresponding tool gun for verification and checking. For parts that do not meet the tool space requirements, it is required to adjust and optimize the product structure.

[0101] MR04: Unified requirements for part fasteners. Please refer to Figure 7 , Figure 7 Figure for the list of fastener models for the charging port in the installation of the high-voltage wire for the electric vehicle charging port. For the fastening of a part, it is required that the fastener models be unified. On the one hand, it is convenient for workers to identify during installation, and on the other hand, it improves the sharing rate of the tool guns on the production line. For parts where the fastener models cannot be unified, generally, it is required that the fastener sizes and torques be unified to ensure the sharing of tool guns as well.

[0102] MR05: Human-machine design requirements for part assembly. Please refer to Figure 8 , Figure 8 Figure for the human-machine design requirements in the installation of the high-voltage wire for the electric vehicle charging port, including the human-machine height for the operation of the high-voltage wire of the charging port, the hand operation space when installing the high-voltage wire base to the vehicle body, etc., which will be further defined and described in the MR entry.

[0103] MR06: Part tooling design requirements. Please refer to Figure 9 , Figure 9 Figure for the partial part tooling design requirements in the installation of the high-voltage wire for the electric vehicle charging port. Generally, considering the actual installation weight and length of the part, tooling is added to facilitate the installation by workers in combination with the on-site operation environment.

[0104] MR07: Part assembly integration requirements. It is required that the high-voltage wire of the charging port, the charging port base, the charging port cover, the charging port cover cable, etc. be designed to be integrated, reducing the number of parts installed on the final assembly line and increasing the integration depth of part design.

[0105] MR08: Requirements for part assembly accuracy. When designing parts, their assembly positioning accuracy needs to be considered. On the one hand, increase part positioning. On the other hand, calculate the installation manufacturing errors of the body mounting through-holes and the parts themselves, cumulative tolerances, etc., to ensure reasonable body openings and accurate part installation, and avoid problems such as offset holes and misaligned holes during actual vehicle installation.

[0106] MR09: Requirements for part assembly quality. Check that the parts are installed in the same direction as the product design digital model after installation, and there is no deformation or stress concentration in the high-voltage wire installation.

[0107] MR10: Requirements for part assembly efficiency. In addition to the part installation positioning requirements, anti-misassembly is also required to avoid workers misassembling and improve assembly efficiency.

[0108] The above are the ten major types of inspection requirements for the high-voltage wire of the charging port. It can be understood that for other parts of the whole vehicle, each specific part of each department is also constrained according to the template of the standard assembly design guide standard.

[0109] In some possible implementation manners of the embodiments of the present application, it is possible to use the part name + MR number of the whole vehicle structure tree, which is convenient for accurately dispatching according to the part name corresponding to the engineer and forming a list.

[0110] Please refer to Figure 10 , Figure 10 which is a design drawing of an assembly design guide list provided by the embodiments of the present application. It can be understood that for this part assembly project, the MR list corresponding to the project can be exported, and the part data number, the department of the part, the engineer corresponding to the part, FFC, and VPPS of the corresponding project can be automatically associated, which is convenient for tracking and managing the status of MR.

[0111] It should be noted that the MR design requirements are different from the on-site installation operation guide documents. The on-site installation guide documents are mainly used to decompose and refine the parts to be installed at each station for guiding on-site workers to assemble the vehicle, while the MR module is mainly for upstream product design engineers to guide part design, so as to consider assembly elements at the design source and avoid problems such as inability to load parts during installation, poor human-machine operation postures for part installation, inability to tighten parts with tools, lack of part installation positioning, lack of anti-misassembly, low installation efficiency, or inability to install due to design defects.

[0112] As a possible implementation manner, generating the vehicle assembly process flow of the vehicle to be assembled according to the pre-built assembly project structure tree includes:

[0113] Generating a general assembly process tree template for the whole vehicle factory according to the pre-built assembly project structure tree;

[0114] Generate the assembly process flows corresponding to the multiple parts according to the general assembly process tree template of the whole vehicle factory and the part parameters corresponding to the multiple parts of the vehicle to be assembled;

[0115] Generate the whole vehicle assembly process flow of the vehicle to be assembled according to the multiple assembly process flows.

[0116] Optionally, the method further includes:

[0117] Determine the whole vehicle process document corresponding to the whole vehicle assembly process flow according to the general assembly process tree template of the whole vehicle factory.

[0118] Next, in combination with another actual scenario, the specific working process of step S102 in the foregoing embodiment, that is, the BOP module, will be introduced.

[0119] Please refer to Figure 11 , Figure 11 , which is a schematic diagram of a general assembly process tree template library provided by an embodiment of the present application. The template library includes information such as sections, station codes, process codes, process names, digital models of tool guns corresponding to the stations, VPPS and functions and FFC information of the corresponding parts, and MR number information.

[0120] Please refer to Figure 12 , Figure 12 , which is a schematic diagram of the whole vehicle assembly process tree exported by the BOP module provided by an embodiment of the present application.
