Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more features.

Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0021] Unless otherwise defined, 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 application pertains. The terminology used in this application's specification is for the purpose of describing particular embodiments only and is not intended to limit the application. It should be understood that, unless otherwise stated, " / " in this application means "or". For example, A / B can mean A or B. "And / or" in this application is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. "At least one" refers to one or more. "More than one" refers to two or more. For example, at least one of a, b, or c can represent: a, b, c, a and b, a and c, b and c, and a, b, and c. Where there is no conflict, the following embodiments and features described herein can be combined with each other.

[0022] With the development of vehicle technology, the demand for new vehicle models is increasing, and virtual manufacturing can shorten the development time of new models, leading to its increasingly widespread application. For example, in the process development of vehicle final assembly, virtual manufacturing can be used to conduct simultaneous engineering (SE) analysis and virtual review activities. Due to the large amount of data on vehicle parts and the rapid updates during new product development, the final assembly process typically uses simulation software (such as Process Simulation software on the TeamCenter platform) for process simulation. However, the simulation process requires manual data processing, setting up interference environments, and performing dynamic path simulations, increasing the labor costs and time cycle of final assembly process simulation, and also limiting its coverage, thus affecting the efficiency of final assembly process simulation.

[0023] Furthermore, due to the large volume of data from the final assembly of the vehicle, offline data storage and processing are time-consuming and labor-intensive. Product data schemes change rapidly, making data download and management difficult when using offline simulation. It is impossible to enter the Process Simulation (PS) environment according to the order of the final assembly process structure tree (BOP) to perform automatic simulation analysis of component assembly paths through simple manual settings. When using already assembled components as environment components for the next component assembly to set interference, manual interference environment settings are time-consuming and the data hierarchy structure tree is overly complex. While automatic path simulation can be performed manually on rigid parts with zero contact, automatic path simulation cannot be performed on other parts with interference such as bolts and nuts. The simulation results for the entire vehicle components cannot generate a complete simulation analysis report, easily leading to the omission of parts. Simulation operators require a high level of professional knowledge and software operation skills, necessitating extensive practice to meet project development schedule requirements.

[0024] To address the issues of increased labor costs, extended simulation time, and limited coverage in the aforementioned simulation of final assembly processes due to manual intervention, which negatively impacts the efficiency of final assembly process simulation, this application provides a final assembly process simulation method. This method can automatically set interference logic, allowing each assembled part to serve as an environmental component for subsequent parts to be assembled, participating in calculations during the automatic path simulation process. This achieves automatic simulation analysis of all vehicle components without manual intervention, saving labor costs and effectively improving the efficiency of final assembly process simulation.

[0025] See Figure 1 The diagram shown is a flowchart of a final assembly process simulation method provided in an embodiment of this application. The final assembly process simulation method is applied to electronic devices and includes: S101, based on the vehicle's Bill of Process (BOP) structure tree, obtain the vehicle's process information.

[0026] In one embodiment of this application, the process structure tree is a structured process data model that organizes all process information in the manufacturing process in a tree structure, including process flow, workstation allocation, resource requirements (e.g., equipment, tools, materials), work methods, quality control, etc. Process information includes, but is not limited to: vehicle component bill of materials (BOM) information, production line information, workstation information, operations, and steps.

[0027] In one embodiment of this application, the vehicle's process structure tree is pre-built and imported into the teamcenter system by the user. After selecting the vehicle model configuration, the process structure tree corresponding to the selected vehicle model is transferred to the processsimulation (PS) software via PS ON TC. The PS software obtains the component BOM information, production line, work station, process, and steps of the selected vehicle model based on the process structure tree.

[0028] S102, determine the type of component based on process information.

[0029] In one embodiment of this application, the component names in the component bill of materials information are identified, and it is determined whether the component name contains a first preset character. If the component name contains the first preset character, the component is determined to be a standard part. For example, standard parts typically include bolts, nuts, etc., and the first preset character is NUT. If the component name does not contain the first preset character, it is determined whether the component name contains a second preset character. If the component name contains the second preset character, the component is determined to be a flexible part. For example, flexible parts typically include wire harnesses, etc., and the second preset character is Harness. If the component name does not contain either the first or the second preset character, the component is determined to be a rigid part. Components identified as rigid parts include not only rigid parts themselves, but also flexible parts whose component names do not contain the first or the second preset character, such as roofs, wheel arch guards, etc.

[0030] S103, set the interference environment of the component based on the type of component.

[0031] In one embodiment of this application, during vehicle assembly simulation, interference refers to the unexpected spatial overlap or collision between two or more components in a virtual assembly or motion state, resulting in parts that cannot be properly installed, have their movement hindered, or malfunction. This overlap may be caused by design errors, dimensional deviations, improper assembly sequence, or conflicting motion paths, and needs to be identified and corrected in advance by simulation software to avoid losses in actual production. In one embodiment of this application, if the gap between two components is less than a preset distance threshold, interference is determined to occur between the two components; if the gap between two components is greater than or equal to the preset distance threshold, interference is determined not to occur between the two components. For example, the preset distance threshold is 2mm.

[0032] In one embodiment of this application, if the component is a standard part, such as a bolt or nut, the component is moved to a non-interference position. Since standard parts are in an interference state when assembled, to achieve automatic simulation, the component is first moved to a non-interference position. Specifically, a rectangular bounding box is defined as the minimum envelope of the component. The component moves along the long side of the rectangular box, and the moving distance is the sum of the length of the rectangular box (i.e., the length of the long side) and a first preset distance, for example, the first preset distance is 2mm, 3mm, 5mm, or other distances. If the component interferes with other components after moving, an interference mark is made.

[0033] In one embodiment of this application, an interference range (i.e., a preset distance threshold) and an automatic path simulation time (e.g., 5 minutes) are set, a simulation link is created, and a virtual assembly relationship between components is established. Assembly path simulation is performed on each component to be assembled according to the process sequence of the line, workstation, operation, and step. Based on process information, the components that need to be fed at each workstation are determined, and the feeding sequence is determined according to the workstation arrangement. For rigid parts and standard parts that have been moved to a non-interference position, interference sets are set. When no components have been imported before the first workstation of a line in the line information, no interference set is set for the components imported before the first workstation. Based on the operation information, multiple components to be assembled at each workstation in the line are paired to form an interference set. When there are imported parts at the first workstation of the line, based on the operation information, the components imported at the first workstation of the line are paired with multiple components to be installed at the first workstation to form an interference set. The interference set includes a first group of components and a second group of components.

[0034] For example, component A is imported before the first station of the production line. The components to be assembled at the first station include components B1, B2, and B3. The imported component A is paired with component B1 at the first station to form an interference set AB1. Interference checks and simulation path planning are then performed. If interference occurs, the interference situation and interference position screenshots of interference sets A and B1 are recorded. If no interference occurs, A and B1 are combined into a whole A1, and then combined with the next component B2 to form a new interference set A1B2, and so on. The above interference check process is performed sequentially until the interference check of all components at the first station is completed. For non-first stations, the components at the first station after interference checks are treated as a whole, and interference sets are set sequentially with the components at non-first stations. The interference situation is compared, and the interference check method is the same as that for the first station.

[0035] In one embodiment of this application, the second group of components in the interference set is moved outside the vehicle body assembly position. Specifically, the second group of components in the interference set is moved to a second preset distance in the Y-axis direction of the vehicle body coordinate system outside the vehicle body assembly position, ensuring that it does not interfere with the first group of components at all. For example, the second preset distance is 2000mm. For example, for the interference set A1B2, A1 is the first group of components, and B2 is the second group of components.

[0036] In one embodiment of this application, if the component is a flexible component, such as a wire harness, it will not participate in the simulation path solving.

[0037] S104, generating assembly paths for components based on the interference environment.

[0038] In one embodiment of this application, the starting and ending points of the second group of components are defined based on the vehicle's body coordinate system. The starting point is the current position of the second group of components, and the ending point is the position of the first group of components. Treating the second group of components as moving objects, the PS software performs path planning based on the Automatic Path Planner command to generate the assembly path for the components.

[0039] In one embodiment of this application, after generating the assembly path of the component, the assembly path includes multiple path points. Interference checks are performed on each path point to ensure that no interference occurs between two interference sets during the movement. If interference occurs between two interference sets, the assembly path simulation is determined to have failed, and a simulation analysis report is output. If no interference occurs between two interference sets, the assembly path simulation is determined to have succeeded, the assembly path is stored, and a simulation analysis report is output.

[0040] In one embodiment of this application, it is determined whether the assembly path simulation of a component is successful within a preset threshold time. If the assembly path simulation of a component is not successful within the preset threshold time, it is determined that the path planning of the component has failed, and the relevant interference set information is recorded. If the assembly path simulation of a component is successful within the preset threshold time, it is determined that the path planning of the component is successful. For example, the preset threshold time is 5 minutes.

[0041] In one embodiment of this application, if interference is detected during path planning, interference set information is automatically recorded, and a screenshot of the interference location is captured. The interference set information and the screenshot of the interference location are then stored in a designated folder.

[0042] The above embodiments of this application can automatically set interference logic so that each assembled component serves as an environment component for subsequent components to be assembled, or a component in the previous process serves as an environment component for a component in the subsequent process, and participates in the calculation during the automatic path simulation process. This realizes automatic simulation analysis of the components of the final assembly vehicle without human intervention, saving labor costs and effectively improving the simulation efficiency of the final assembly process.

[0043] See Figure 2 The diagram shown is a flowchart of a final assembly process simulation method provided in another embodiment of this application. The final assembly process simulation method is applied to electronic devices and includes: S201, based on the vehicle's process structure tree, obtain the vehicle's process information.

[0044] S202, determine the type of component based on process information.

[0045] S203, set the interference environment of the component based on the type of component.

[0046] S204, generating assembly paths for components based on the interference environment.

[0047] The specific implementation methods of S201-S204 are the same as those of S101-S104, and will not be described in detail here.

[0048] S205 generates a simulation analysis report based on the interference of components and the simulation of the assembly path.

[0049] In one embodiment of this application, the simulation analysis report corresponding to interference includes the interference set and related interference images, while the simulation analysis report corresponding to assembly path generation failure includes interference set information for paths that were not successfully planned. The two types of simulation analysis reports are output separately, and the output files include necessary supporting files, such as screenshots and logs, to ensure information completeness and ease of subsequent querying and analysis. Specific files can be named and stored in a specified path.

[0050] In one embodiment of this application, the simulation analysis report may further include the total number of simulated components, the number of components corresponding to successful path simulation, and the number of components corresponding to failed path simulation. Components corresponding to failed path simulation in the simulation analysis report are typically flexible parts or parts with large interference in their final assembly state; these parts require manual analysis and confirmation.

[0051] Based on the above embodiments of this application, automatic simulation analysis of vehicle components according to the BOP (Building Operator's Plane) is achieved, replacing the original manual analysis method with an automatic one. Interference logic is automatically set, making each assembled part an environment for subsequent assembly parts, participating in calculations during automatic path simulation. Through experience summarizing the types and assembly characteristics of assembly components, automatic path simulation can be performed on interference-related components such as bolts and nuts. A complete simulation analysis report is generated for the components involved in the simulation analysis. This reduces the time and error rate of online and offline data transfer, improving the efficiency of assembly process development. Significant time is saved in data processing, interference environment setting, and manual simulation analysis. A complete BOP simulation analysis report is generated, providing data support for SE (Search Engine Analysis) and virtual review. The operation is simple, reducing personnel learning costs and improving work efficiency.
