Attached Figure Description

Several embodiments of the invention are illustrated in the drawings by way of example and not limitation, wherein:

[0022] In the accompanying drawings, the same or corresponding reference numerals indicate the same or corresponding parts. Detailed Implementation

[0023] The principles and spirit of the invention will now be described with reference to several exemplary embodiments. It should be understood that these embodiments are given merely to enable those skilled in the art to better understand and implement the invention, and are not intended to limit the scope of the invention in any way.

[0024] In one aspect, embodiments of the present invention provide a method for analyzing the assemblability of an automobile. (See reference...) Figure 1 The diagram illustrates a flowchart of an example of a vehicle assemblability analysis method according to an embodiment of the present invention. The method includes steps S101-S107.

[0025] In step S101, the user-inputted part assembly information is received. This part assembly information may be an identifier for a part assembly under a specific vehicle model.

[0026] In step S102, the hierarchical information of the component assembly is obtained based on the component assembly information, wherein the hierarchical information includes the hierarchical relationship and the part number of the component included in each level.

[0027] In step S103, the assembly data of each part in the assembly is obtained according to the hierarchical information. For example, an operation command is issued to a Computer Aided Three-dimensional Interactive Application (CATIA) to load the assembly data of the parts.

[0028] In step S104, process information (VE) data items are deleted from the assembly data to generate filtered assembly data. Process information may include, for example, information on adhesive application and solder joints. Since this information interferes with the parts, removing the process information in advance can reduce interference with subsequent interference matching processing and reduce the amount of computation.

[0029] In step S105, based on the filtered assembly data and hierarchical information, the gap data and part graphics between each part are obtained. For example, the gap data can be obtained by calling a database or system that stores gap data, and the data can be collected and entered into the system database. The gap data is, for example, the specific numerical value of the gap between parts.

[0030] In step S106, the interference matching analysis of the parts is performed based on the gap data to determine the parts that interfere with each other.

[0031] In one embodiment of the present invention, the method may further include: receiving a user-defined gap requirement. In this embodiment, step S106 may include: determining whether the gap data meets the user-defined gap requirement. The user-defined gap requirement may be a pre-set and stored default gap requirement, or it may be set separately for each run.

[0032] In another embodiment of the present invention, step S106 may include: determining whether the gap data is within one or more preset gap thresholds.

[0033] In another embodiment of the present invention, step S106 may include: determining the gap state between each part based on gap data, wherein the gap state includes a large gap state, a close-fitting state, and an interference state. For example, two gap thresholds may be set: a gap greater than or equal to a first threshold is determined to be a large gap state; a gap less than the first threshold but greater than or equal to a second threshold is determined to be a close-fitting state; and a gap less than the second threshold is determined to be an interference state.

[0034] In step S107, the part numbers and part graphics of the interfering parts are output. The output part numbers and part graphics can be displayed on the human-machine interface. The part graphics of the interfering parts show a screenshot of the interference position. For example, different interference states can be marked with different colors in the displayed part graphics; for example, interfering parts are marked in red, and non-interfering parts are marked in green.

[0035] The steps S101-S107 described above implement the data interference function in the product assemblability inspection. This data interference function uses the program to intelligently extract the contact information of parts, analyze and output an interference report, enabling the inspection of small modules in large assemblies, refining the inspection granularity and improving analysis efficiency.

[0036] As one embodiment of the present invention, the automotive assemblability analysis technology solution proposed in this embodiment may further include plate thickness analysis function and / or data comparison function. For example... Figure 2 As shown.

[0037] As one embodiment of the present invention, corresponding to the plate thickness analysis function, the method may further include the following steps:

[0038] Extract the sheet metal thickness and manufacturing process (VE) information of the part assembly based on the part assembly information. For example, a loading command can be sent to the CATIA system, and the system's part information acquisition module can be used to collect the sheet metal thickness and manufacturing process information of the vehicle model data and enter it into the system database.

[0039] The welding component combinations in the part assembly can be matched based on the weld points in the process information. For example, all part combinations can be matched using the weld point data in the VE information.

[0040] Based on the plate thickness information of the parts in each welding assembly and the pre-set welding material plate thickness rules, determine the plate thickness non-compliance points and the welding assembly in which they are located. The pre-set welding material plate thickness rules may include, for example, whether two or three plates can be welded together; upper and lower thresholds for the thickness of plate A + plate B; if the thickness of plate A is greater than a certain value, the thickness of plate B cannot be greater than another value; and what range the thicknesses of plate A and plate B should each fall within when the sum of their plate thicknesses falls within a certain range, etc.

[0041] The system outputs the non-conforming plate thickness points and their associated welded component combinations. For example, it can output the calculated non-conforming points and statistical data (e.g., the total number of non-conforming points, the combination to which each non-conforming point belongs, and the plate thickness) to the system interface, displaying the required information to the user, including non-conforming points analyzed for plate thickness and a statistical bar chart showing the number of non-conforming combinations. Alternatively, it can highlight non-conforming points in red or issue alert messages in the displayed component graphics for user reference.

[0042] The above steps realize the plate thickness analysis function, use the program to intelligently extract data information, analyze plate thickness in batches, and output reports. This eliminates the complicated operations and calculation error rate caused by manual operation, and effectively improves analysis efficiency and judgment accuracy.

[0043] As one embodiment of the present invention, corresponding to the data comparison function, the method may further include: receiving the part number to be analyzed and the comparison vehicle item number input by the user; loading the part file of the comparison vehicle item according to the comparison vehicle item number; and outputting and displaying the part information in the part file of the comparison vehicle item corresponding to the part number to be analyzed.

[0044] For example, the system identifies user-submitted part information (e.g., part number, unique identifier for a part under a specific item) and comparison vehicle information (e.g., item number selected by the user). The system then generates all part numbers matching each comparison item, transmits instructions to a specific technical network (e.g., a parts data network), downloads the corresponding 3D data from the website, downloads the required part files to a designated location, and sends operation instructions to the CATIA system to load the part files. Simultaneously, the system's data acquisition module collects data, analyzes and processes the data, and outputs it to the system interface to display the required information to the user, including part numbers and comparison graphics. For instance, when comparing headlights, the system can compare data and graphics of headlights from multiple vehicle models, displaying the headlight's size and structure for the user's viewing.

[0045] The above steps enable data comparison, allowing the program to quickly extract data from various vehicle models, perform batch analysis, and eliminate the tedious process of manual processing, thereby improving analysis efficiency.

[0056] The welding component assembly matching module 402 can be configured to match the welding component assemblies in the component assembly based on the weld points in the process information.

[0058] The plate thickness non-conforming point output module 404 can be configured to output plate thickness non-conforming points and the welding part assemblies in which they are located.
