[0063] This embodiment identifies the operation instructions used to construct each part simulation model during the construction of the simulation models of the target body-in-white. When the operation instruction belongs to the target operation instruction, the attribute parameters of the corresponding part simulation model are determined according to the target operation instruction, and the corresponding attribute parameters are associated with the part simulation model.

Attached Figure Description

[0064] To more clearly illustrate the technical solutions in the embodiments of the present invention, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0067] Figure 3 This is a schematic diagram of the structure of an electronic device provided in this embodiment. Detailed Implementation

[0068] This application provides a bill of materials (BOM) generation method, which solves the technical problem in the prior art where the attribute parameters of each part are manually recorded and a BOM is generated by manually comparing the simulation model of the white body, resulting in low BOM generation efficiency.

[0069] The technical solution of this application embodiment is to solve the above-mentioned technical problems, and the general idea is as follows:

[0070] This embodiment identifies the operation instructions used to construct each part simulation model during the construction of the simulation models of the target body-in-white. When the operation instruction belongs to the target operation instruction, the attribute parameters of the corresponding part simulation model are determined according to the target operation instruction, and the corresponding attribute parameters are associated with the part simulation model. After constructing each part simulation model of the target body-in-white, the target bill of materials (BOM) for the target body-in-white is generated according to the assembly category corresponding to each part simulation model and the association relationship between the assembly categories, based on the associated attribute parameters and the part simulation model. It is evident that this embodiment, during the construction of each part simulation model of the body-in-white, collects the attribute parameters corresponding to each part simulation model according to the target operation instructions during the construction process. This avoids the method of manually collecting attribute parameters from the completed body-in-white simulation model in related technologies, greatly improving the efficiency of BOM generation, avoiding errors in the manual collection process, significantly reducing the error rate of attribute parameters in the BOM, improving the accuracy of the BOM, reducing the probability of errors in subsequent bidding and mold development, reducing the impact on the project cycle, and reducing mold repair costs. To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0071] First, it should be clarified that the term "and / or" in this article 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 existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0072] A Bill of Materials (BOM) is a document that describes the structure of a product in a data format; it is a computer-readable product structure data file. A BOM is also required in the design of automotive body-in-white. The BOM needs to include information such as the weight, thickness, material, version, and weld points of the parts. In related technologies, this is mainly achieved by manually measuring the 3D data of the existing body-in-white simulation model and then filling the manually measured attribute parameters into the BOM.

[0073] However, body-in-white simulation models typically contain at least several hundred parts, resulting in low BOM generation efficiency. Furthermore, parameter changes during the development of the body-in-white simulation model necessitate multiple manual revisions of the BOM, further reducing generation efficiency. Additionally, manual measurement leads to discrepancies between the attribute parameters in the BOM and the 3D data of the body-in-white simulation model, resulting in low accuracy of the BOM's attribute parameters. This can cause misleading guidance in subsequent bidding and mold development processes, impacting project timelines and incurring mold repair costs.

[0074] To address the aforementioned problems, this embodiment provides the following: Figure 1 The method for generating a bill of materials includes steps S11-S13.

[0075] Step S11: In the process of constructing simulation models of each part of the target body-in-white, identify the operation instructions used to construct the simulation model of each part.

[0076] Step S12: When the operation instruction belongs to the target operation instruction, determine the attribute parameters of the corresponding part simulation model according to the target operation instruction, and associate the corresponding attribute parameters with the part simulation model;

[0077] Step S13: After constructing the simulation models of each part of the target body-in-white, the target bill of materials for the target body-in-white is generated according to the assembly categories corresponding to each part simulation model and the relationships between each assembly category, based on the attribute parameters of each association and the part simulation model.

[0078] The bill of materials generation method provided in this embodiment can be executed by a terminal that creates a simulation model of the target body-in-white parts, or by other devices connected to the terminal that creates the simulation model of the target body-in-white parts. This embodiment does not impose any restrictions on this.

[0079] Regarding step S11, during the process of constructing simulation models of each part of the target body-in-white, the operation instructions used to construct the simulation model of each part are identified.

[0080] Body-in-white (BIC) refers to the car body that has been welded but not yet painted. During the development of BIC, a virtual simulation model of the BIC needs to be created first; this involves using 3D software to create a 3D virtual simulation model of the BIC. In this embodiment, BIC will refer to the 3D simulation model of the BIC.

[0081] The target body-in-white consists of several different assemblies, which may include the body-in-white welded assembly, hood, front and rear doors, trunk lid, tailgate, fenders, etc. The body-in-white welded assembly may include the front compartment assembly, floor assembly, side panel assembly, roof assembly, rear panel assembly, etc. Each different assembly includes several different parts.

[0082] In the process of creating a 3D simulation model of the body-in-white, we first construct simulation models of various parts, then assemble the different parts simulation models into corresponding assembly simulation models, and finally assemble the various assembly simulation models into the body-in-white to obtain the final 3D simulation model of the body-in-white.

[0083] In the process of constructing simulation models of various parts of the target body-in-white, it is necessary to use various instructions from 3D software to create them, identify the operation instructions used to construct the simulation model of each part, and determine whether they are the target operation instructions.

[0084] Target operation instructions refer to operation instructions in 3D software that affect the attribute parameters that need to be recorded in the BOM (Bill of Materials). For example, if the BOM needs to record information such as material thickness, weight, material, weld points, and adhesive application, then the target operation instructions can be operation instructions in 3D software that affect the material thickness, weight, material, weld points, and adhesive application of the simulation model of each part of the target body-in-white.

[0085] For each part simulation model corresponding to the target white body, if the operation instruction used to construct the part simulation model is not the target operation instruction, the method provided in this embodiment does not need to be executed. If the operation instruction used to construct the part simulation model is the target operation instruction, then step S12 is executed.

[0086] Regarding step S12, when the operation instruction belongs to the target operation instruction, the attribute parameters of the corresponding part simulation model are determined according to the target operation instruction, and the corresponding attribute parameters are associated with the part simulation model.

[0087] When an operation instruction is a target operation instruction, the corresponding attribute parameters of the part simulation model are determined based on the target operation instruction. Target operation instructions may include at least one of the following: surface offset instruction, material setting instruction, standard part recall instruction, spot welding instruction, MIG / MAG welding instruction, and adhesive application instruction. In addition to the target operation instructions mentioned in this embodiment, other target operation instructions can be added according to the attribute parameters actually needed to be recorded in the BOM table; this embodiment will not elaborate on these. This embodiment only uses the surface offset instruction, material setting instruction, standard part recall instruction, spot welding instruction, MIG / MAG welding instruction, and adhesive application instruction as examples for explanation.

[0088] When the target operation command is a surface offset command, the material thickness parameters of the corresponding part simulation model are determined based on the offset distance of the surface offset command. Body-in-white parts are typically sheet metal, and their material thickness is primarily determined through surface offset during 3D simulation model construction. When the 3D software detects the use of a surface offset command, the offset distance of the surface offset command is used as the material thickness parameter of the part simulation model.

[0089] When the target operation command is a material setting command, the density parameters of the corresponding part simulation model are determined based on the material setting command; the weight parameters of the corresponding part simulation model are determined based on the volume parameters and density parameters. For each part simulation model of the body-in-white, the materials used in its manufacturing process need to be set, such as steel plates or aluminum plates. Once the 3D software recognizes that it has executed a material setting command, it can determine the density parameters of the part simulation model based on the specified material type. Then, based on the volume calculation of the 3D software, the volume parameters of the part simulation model are determined. Combining the volume parameters and density parameters, the weight parameters of the part simulation model can be determined.

[0090] When the target operation command is a standard part call command, the standard part parameters of the corresponding part simulation model are determined based on the standard part call command. Standard parts refer to accessories such as bolts and nuts used on the body-in-white; these standard parts are pre-built simulation models. When the 3D software recognizes the use of a standard part call command, the standard part parameters of the part simulation model are determined based on the type of standard part called by the command. The standard part parameters may include the quantity and type of standard parts used in this part simulation model, the total weight parameters of standard parts of the same type, and the dimensional information of each standard part.

[0091] When the target operation command is a spot welding command, the number of spot welds in the corresponding part simulation model is determined based on the total spot weld area and the area of ​​a single spot weld. Body-in-white panels involve spot welding; some part simulation models involve spot welding of two layers of steel plates (denoted as two-layer welds), some involve spot welding of three layers of steel plates (denoted as three-layer welds), and some may involve both two-layer and three-layer spot welds simultaneously. When a spot welding command is detected from the 3D software, the total spot weld area of ​​all welds on the part simulation model can be combined into a surface. Dividing the area of ​​this surface by the area of ​​a single spot weld determines the number of spot welds on the part simulation model. The number of spot welds for both two-layer and three-layer welds can be calculated by dividing the total spot weld area by the area of ​​a single spot weld. It's important to note that you can either calculate the number of spot welds by dividing the total area of ​​each spot weld by the area of ​​a single spot weld, or you can identify whether a spot weld command has been used on the simulation model of the current part after it has been built. If a spot weld command has been executed, then calculate the number of spot welds by dividing the total area of ​​each spot weld by the area of ​​a single spot weld. You can choose between these two methods based on your needs during actual operation.

[0092] When the target operation command is a MIG / MAG welding command, the MIG / MAG welding length of the corresponding part simulation model is determined based on the first running length of the MIG / MAG welding command. MIG / MAG welding is a welding method that actually uses welding rods to weld a certain length. When constructing a part simulation model in 3D software, the MIG / MAG welding curve is mainly drawn using MIG / MAG welding commands to simulate the MIG / MAG welding process. When the use of MIG / MAG welding commands in the 3D software is detected, the sum of the first running lengths of all MIG / MAG welding commands corresponding to the part simulation model can be used as the MIG / MAG welding length of the part simulation model (i.e., representing the total length).

[0093] When the target operation command is an adhesive application command, the type of target adhesive strip corresponding to the command is identified. Based on the second running length of the command for that type of adhesive strip, the target adhesive strip length on the corresponding part simulation model is determined. Adhesive application commands may define different types of adhesive strips, such as spot welding sealant, weld sealant, structural adhesive, and expanding adhesive. In 3D software, adhesive application commands are primarily used to draw adhesive application curves to simulate the application process. When the use of an adhesive application command in the 3D software is detected, the type of target adhesive strip corresponding to the command is first identified, and then the second running length of the command corresponding to that type is determined as the target adhesive strip length. It is important to note that for the same part simulation model, what needs to be determined is the sum of the adhesive strip lengths corresponding to different types of adhesive strips on the model. Therefore, the sum of the second running lengths corresponding to the same type of adhesive strip is used to determine the target adhesive strip length for that type of adhesive strip on the part simulation model.

[0094] During the construction of simulation models of each part of the target body-in-white, step S12 needs to be executed for the target operation command corresponding to each part simulation model. After all the part simulation models of the target body-in-white are completed, step S13 can be executed.

[0095] Regarding step S13, after constructing the simulation models of each part of the target body-in-white, the target bill of materials for the target body-in-white is generated according to the assembly categories corresponding to each part simulation model and the relationships between each assembly category, based on the attribute parameters of each association and the part simulation model.

[0096] After constructing simulation models of all parts of the target body-in-white, they can be assembled according to the assembly category to which each part simulation model belongs, to obtain the assembly simulation model of the corresponding assembly category; then, according to the relationship between the assembly categories, the assembly simulation models corresponding to each assembly category are assembled to obtain the target body-in-white.

[0097] Based on the assembly categories corresponding to each component simulation model and the relationships between these assembly categories, a blank bill of materials (BOM) with a preset format is generated. The blank BOM includes assembly category identifiers for different assembly categories, component identifiers for each component simulation model corresponding to each assembly category, and identifiers for the attribute parameters of each component simulation model, such as material thickness parameter identifiers, weight parameter identifiers, standard part parameter identifiers, spot weld quantity identifiers, MIG / MAG weld length identifiers, and target adhesive strip length identifiers.

[0098] By filling the corresponding positions in the blank bill of materials with the associated attribute parameters and part simulation models, the target bill of materials (BOM) for the target body-in-white is obtained. For example, fill the material thickness parameter into the position corresponding to the material thickness parameter identifier, fill the weight parameter into the position corresponding to the weight parameter identifier, fill the standard part parameter into the position corresponding to the standard part parameter identifier, fill the spot weld quantity into the position corresponding to the spot weld quantity identifier, fill the MIG weld length into the position corresponding to the MIG weld length identifier, and fill the target adhesive strip length into the position corresponding to the target adhesive strip length identifier, thus obtaining the target BOM for the target body-in-white.

[0099] The preset bill of materials format can be set according to actual needs. For example, an Excel macro program can be used to output and organize the bill of materials into the required body-in-white BOM format. The information in the tables can be collected, arranged into a structure tree order, and the body-in-white BOM can be output according to the project requirements.

[0100] In summary, this embodiment identifies the operation instructions used to construct each part simulation model during the construction of the simulation models of the target body-in-white. When the operation instruction belongs to a target operation instruction, the attribute parameters of the corresponding part simulation model are determined according to the target operation instruction, and the corresponding attribute parameters are associated with the part simulation model. After constructing each part simulation model of the target body-in-white, the target bill of materials (BOM) for the target body-in-white is generated according to the assembly category corresponding to each part simulation model and the association relationship between each assembly category, based on the associated attribute parameters and the part simulation model. It is evident that this embodiment, during the construction of each part simulation model of the body-in-white, collects the attribute parameters corresponding to each part simulation model according to the target operation instructions during the construction process. This avoids the manual collection of attribute parameters from the completed body-in-white simulation model in related technologies, greatly improving the efficiency of BOM generation, avoiding errors during manual collection, significantly reducing the error rate of attribute parameters in the BOM, and improving the accuracy of the BOM. This can reduce the probability of errors in subsequent bidding and mold development, reduce the impact on the project cycle, and reduce mold repair costs.

[0101] After constructing simulation models of each part of the target body-in-white, or after generating the target bill of materials for the target body-in-white based on the associated attribute parameters and the part simulation models, the method further includes steps S21-S23.

[0102] Step S21: Receive modification instructions for modifying the simulation model of the target part of the target body-in-white;

[0103] Step S22: When the modification instruction is a target operation instruction, update the attribute parameters associated with the target part simulation model according to the modification instruction;

[0104] Step S23: Update the bill of materials for the target body-in-white based on the updated attribute parameters.

[0105] After all the simulation models of each part have been built, or after the target bill of materials has been generated, when a modification instruction is received for certain simulation models of parts (in this embodiment, the simulation models of parts that need to be modified are referred to as target simulation models), the system responds to these modification instructions and determines whether these modification instructions belong to the target operation instructions.

[0106] When the modification instruction is a target operation instruction, the attribute parameters associated with the target part simulation model are updated according to the modification instruction. That is, the attribute parameters corresponding to the target part simulation model are redefined according to the modification instruction, and the redefined attribute parameters are used as the attribute parameters corresponding to the target part simulation model. The updated attribute parameters are then updated in the target bill of materials.

[0107] In summary, this embodiment identifies the modification instructions corresponding to the part simulation model, automatically updates the attribute parameters of the part simulation model, and synchronously updates the target bill of materials (BOM). During the development of the body-in-white, each part simulation model may undergo repeated modifications. The method provided in this embodiment can automatically update the attribute parameters of the modified part simulation models in real time, avoiding the manual updating of attribute parameters used in related technologies. This significantly improves the efficiency of BOM modification and avoids errors during manual correction, greatly reducing the probability of inconsistencies between the BOM and the parameters of each part simulation model, thus improving the accuracy of the BOM. This can reduce the likelihood of misleading decisions in subsequent bidding and mold development, lessen the impact on project timelines, and reduce mold repair costs.

[0108] After generating the target bill of materials for the target body-in-white based on the associated attribute parameters and the part simulation model, the method also includes steps S31-S32.

[0109] Step S31: Obtain part images of the simulation models of each part of the target body-in-white; it is also possible to obtain assembly images of the assembly simulation models corresponding to the assembly categories of multiple part simulation models.

[0110] Step S32: Save the part images of each part simulation model to the corresponding part folder. The name of the part folder is the same as the name of the corresponding part simulation model. Save the assembly images of each assembly category assembly simulation model to the corresponding assembly folder. The name of the assembly folder is the same as the name of the corresponding assembly simulation model. Alternatively, the part folders corresponding to each part simulation model belonging to the assembly simulation model can be placed in the assembly folder corresponding to the assembly simulation model.

[0111] Specifically, the assembly structure tree of the target body-in-white can be constructed according to the assembly category corresponding to each part simulation model and the relationship between each assembly category; the simulation models of each part corresponding to each assembly category can be traversed according to the assembly structure tree; and the part images of each simulation model of the target body-in-white can be obtained in the order of traversal.

This facilitates the project team to evaluate the composition information and cost changes of body parts in a timely manner, greatly improves work efficiency, fully meets the needs of short project cycles, and reduces design errors.
