Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a material data verification method and device. Background Art

[0002] The application of vehicle-level BOM (Bill of Material) in the automotive industry involves all aspects of automobile manufacturing companies. It records in detail all the lower-level materials and related properties used in a project, that is, the subordinate relationship between the parent part and all the sub-parts, unit usage and other properties. At the same time, BOM is an indispensable and important document in the fields of R&D design, production and manufacturing, purchase orders, and logistics tracking, involving multiple fields of enterprise R&D, manufacturing, procurement, and logistics.

[0003] Vehicle product design is the first step in the construction of BOM data. The accuracy of this data determines the basis of BOM data precision, and subsequent BOM data is generated on this basis. At the same time, the vehicle-level BOM data volume is large, including structural information, usage information, logistics information, etc. Therefore, in order to ensure that the full amount of data in the BOM is consistent with the product design data status, and the difference with the downstream full-chain business data is controllable, it is necessary to regularly, accurately and systematically check various information in the BOM with product design data and downstream business data.

[0081] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0082] The embodiments of the present application are further described in detail below in conjunction with the accompanying drawings.

[0083] The embodiments of the present application provide a material data verification method and device, which can comprehensively verify all business scenario data in the BOM and improve the accuracy of vehicle-level BOM data verification.

[0084] In order to achieve the above technical effects, the overall idea of ​​this application is as follows:

[0085] A material data verification method, the method comprising the following steps:

[0086] S1. Obtaining structural verification results based on the interface structural information of the 3D model of the assembly parts and the interface structural information of the actual assembly parts;

[0087] S2, obtaining a manufacturing verification result based on the interface structure information of the assembly part 3D model and the interface structure information of the opponent part matching the assembly part 3D model;

[0088] S3, obtaining logistics verification results based on the assembly environment information of the 3D model of the assembly parts and the process logistics information of the actual assembly parts;

[0089] S4. Obtain material data verification results of the assembly part 3D model according to the structure verification results, the manufacturing verification results and the logistics verification results.

[0090] The embodiments of the present application are further described in detail below in conjunction with the accompanying drawings.

[0091] See also Figure 1As shown, the embodiment of the present application provides a material data verification method, which includes the following steps:

[0092] S1. Obtaining structural verification results based on the interface structural information of the 3D model of the assembly parts and the interface structural information of the actual assembly parts.

[0093] Among them, the 3D model of the assembly parts is constructed based on the size data of the actual assembly parts, and the data information of each interface with the actual assembly parts is stored in the database of the 3D model virtual construction environment.

[0094] The docking interface data information refers to the docking interface information between the assembly parts and other counterpart parts, including the size information, style information and number information of the docking interface.

[0095] Specifically, when performing full data verification of the vehicle-level BOM, the interface structure information on the 3D model of the assembly parts is obtained from the database of the 3D model virtual construction environment, such as CATIA.

[0096] In this step, the 3D model of the assembly part can be displayed in full dimensions in the CATIA virtual construction environment, and then the inspector can compare the docking interface of the 3D model of the assembly part with the docking interface on the actual assembly part through manual observation. If the structure of the docking interface of the 3D model of the assembly part is observed to be consistent with the docking interface of the actual assembly part, the result information of successful structural verification is output.

[0097] S2. Obtain manufacturing verification results based on the interface structure information of the assembly part 3D model and the interface structure information of the opponent part that matches the assembly part 3D model.

[0098] It is understandable that vehicle assembly is one of the most important technological links in the vehicle manufacturing process. It is a process of assembling hundreds or thousands of various parts that have passed inspection into complete vehicles and assemblies such as engines and transmissions according to certain technical requirements.

[0099] Therefore, the adaptability of the interface structure between the assembly parts and the docking parts is particularly important for the accuracy of assembly.

[0100] Specifically, each type of assembly part has a number corresponding to it, and the number of the opponent part matching the assembly part can be found in the database according to the number of the assembly part, and the structural information of the docking interface on the opponent part of this type can be obtained according to the number of the opponent part.

[0101] Then, the structural information of the docking interface on the assembly part is matched with the structural information of the docking interface on the opponent part. If the docking interfaces of the two can be completely matched, the result information of successful manufacturing verification of the assembly part and its corresponding opponent part is output.

[0102] S3. Obtain logistics verification results based on the assembly environment information of the 3D model of the assembly parts and the process logistics information of the actual assembly parts.

[0103] The assembly information refers to the connection environment information between the assembly parts and the vehicle body structure or other accessories on the vehicle during the assembly process. The assembly information is obtained after all the 3D models of the assembly parts are assembled.

[0104] Process logistics information refers to the logistics distribution information of assembly parts, that is, the information indicating that the assembly parts are transported to the processing location. For example, the processing location can be an engine, a car body, etc.

[0105] Specifically, the assembly environment information of the assembly part 3D model is obtained, and the connection between the assembly part 3D model and other structures in the whole vehicle is parsed from the assembly environment information, and then the process logistics information list is imported, and the logistics information of the assembly part is retrieved from the list. Then, the ownership information of the assembly part 3D model is obtained according to the connection between the assembly part 3D model and other structures in the whole vehicle, and the ownership information is compared with the process logistics information:

[0106] If the process logistics information is consistent with the attribution information, the result information of successful logistics verification is output;

[0107] If the process logistics information is inconsistent with the attribution information, the result information of unsuccessful logistics verification will be output.

[0108] S4. Obtain material data verification results of the assembly parts 3D model based on the structure verification results, manufacturing verification results and logistics verification results.

[0109] Specifically, when the structural verification results, the manufacturing verification results, and the logistics verification results are all verified to be passed, it means that the material data verification of the assembly part 3D model is successful.

[0110] This application constructs a 3D model of assembly parts in a virtual environment based on the structure and size of actual assembly parts, and performs structural verification, manufacturing verification, and process logistics information verification on the 3D model of assembly parts in combination with the process logistics information, size information, and structural information of the actual assembly parts. This allows comprehensive verification of all business scenario data in the BOM, thereby improving the accuracy of vehicle-level BOM data verification.

[0111] It is understandable that before performing structural verification, manufacturing verification, and logistics verification on the 3D model of the assembly parts, it is necessary to first model all the actual assembly parts in the vehicle.

[0112] Before implementing the material data verification method, the following steps are required:

[0113] S5. Based on the hierarchical structure of each component in the actual assembly part, assemble each component to construct a 3D model of the assembly part.

[0114] As is known to all, the main components of a vehicle are composed of five basic parts: engine, chassis, body, electrical equipment, and tires. The vehicle parts to be assembled are part or all of the parts for assembling the main components of the vehicle. The dimensional measurement data of the vehicle parts to be assembled can be obtained by measuring each of the vehicle parts to be assembled using a measuring device.

[0115] Specifically, the hierarchical structure of each component in the actual assembly part and the dimensional data of each assembly component are obtained, and the 3D model of each assembly part is constructed in the virtual model using the hierarchical structure of each component and the dimensional data of the component to be assembled.

[0116] S6. Obtaining interface structure information in the 3D model of the assembly part and interface structure information of the opponent part matching the 3D model of the assembly part.

[0117] The interface structure information in the 3D model of the assembly parts includes interface style information, interface quantity information, interface size information, etc.

[0118] Specifically, the interface structure information in the 3D model of the assembly part and the interface structure information of the opponent part matching the 3D model of the assembly part are obtained from the 3D model virtual generation environment.

[0119] In this embodiment, according to the dimensions of the actual assembly parts and the structure of the virtual 3D model, the structural information verification, manufacturing information verification, and process logistics information verification can be performed simultaneously. All business scenario data in the BOM can be comprehensively verified to improve the accuracy of vehicle-level BOM data verification.

[0120] In one embodiment, step S1 further includes the following steps:

[0121] S101, based on the interface structure information of the 3D model of the assembly parts, obtaining model interface size information and model interface relative position information;

[0122] The interface structure may generally be a buckle, a screw, etc. The interface size information may be the diameter and style information of the buckle or the screw.

[0123] Specifically, the size information of the interface and the relative position information of the interface in the 3D model of the assembly part are parsed from the interface structure information of the assembly part 3D model.

[0124] S102, based on the interface structure information of the actual assembly parts, obtaining actual interface size information and actual interface relative position information;

[0125] S103: Compare the model interface size information and the model interface relative position information with the actual interface size information and the actual interface relative position information respectively to obtain a structure verification result.

[0126] Specifically, the model interface size information is compared with the actual interface size information to obtain a first structure verification result;

[0127] Comparing the model interface relative position information with the actual interface relative position to obtain a second structure verification result;

[0128] If the first verification result and the second verification result both pass the verification, based on the first structure verification result and the second structure verification result, a structure verification result is obtained.

[0129] In this embodiment, by comparing the model interface size information and the model interface relative position information with the actual interface size information and the actual interface relative position information, respectively, the problem of inconsistency between the assembly part model and the actual assembly parts or even missing parts in the 3D model of the assembly parts is avoided during the 3D modeling process, thereby ensuring the accuracy of the assembly parts during the 3D modeling process.

[0130] In one embodiment, step S2 further includes the following steps:

[0131] S201, based on the interface structure information of the assembly part 3D model, obtaining interface style information and interface quantity information of the assembly part 3D model;

[0132] Specifically, the interface style information and interface quantity information of the assembly part 3D model are obtained by parsing the interface structure information of the assembly part 3D model.

[0133] S202, based on the interface structure information of the opponent's part, obtaining the interface style information and interface quantity information of the opponent's part;

[0134] Specifically, the interface style information and interface quantity information of the assembly part 3D model are obtained by parsing the interface structure information of the assembly part 3D model.

[0135] S203, comparing the interface style information and interface quantity information of the 3D model of the assembly part with the interface style information and interface quantity information of the opponent's part, to obtain a manufacturing verification result.

[0136] Specifically, firstly, the interface style information of the assembly part 3D model is compared with the interface style information of the opponent's part to obtain the first manufacturing verification result;

[0137] Compare the interface quantity information of the 3D model of the assembly part with the interface quantity information of the opponent's part to obtain a second manufacturing verification result;

[0138] For example, if the counterpart part of a 3D model of an assembly part is an engine cooling water pipe, the counterpart part number is matched according to the 3D model number of the assembly part, and the corresponding interface style information and quantity information of the part are obtained according to the counterpart part number.

[0139] Figure 2 The engine cooling water pipe assembly part in the 3D model has two clips E, and Figure 3 However, the BOM data of the engine cooling water pipe assembly shows that this type of engine cooling pipe should have 3 clips E.

[0140] Therefore, it can be seen that the 3D model of this type of engine cooling water pipe does not match the assembly part, that is, the second manufacturing verification result is failed.

[0141] Based on the first manufacturing verification result and the second manufacturing verification result, a manufacturing verification result is acquired.

[0142] Specifically, if both the first manufacturing verification result and the second manufacturing verification result are passed, it means that the manufacturing verification result is passed; if either the first manufacturing verification result or the second manufacturing verification result is failed, it means that the manufacturing verification result is failed.

[0143] In this embodiment, the interface style information and interface quantity information of the assembly part 3D model are compared with the interface style information and interface quantity information of the opponent part, respectively, to obtain the manufacturing verification result, thereby avoiding the problem of the assembly part model not matching the opponent part 3D model during the 3D modeling process and ensuring the accuracy of the assembly part during the 3D modeling process.

[0144] In one embodiment, step S3 includes:

[0145] S301, obtaining interference information of the assembly parts based on the assembly environment information of the 3D model of the assembly parts;

[0146] According to the assembly environment information of the 3D model of the assembly part, the connection status of the assembly part, the vehicle structure and the 3D model of the assembly part, that is, the interference information of the assembly part, is obtained.

[0147] S302, determining the attribution information of the 3D model of the assembly parts according to the interference information of the 3D model of the assembly parts;

[0148] Specifically, the processing workshop of the 3D model of the assembly part is determined according to the interference information of the assembly part. For example, the two assembly parts, the bracket and the horn, are only connected to the body, and are not connected to other vehicle structures or other assembly parts. Therefore, the ownership information of the two assembly parts, the bracket and the horn, should be the body workshop.

[0149] S303. Compare the attribution information with the process logistics information to obtain logistics verification results.

[0150] The process logistics information of the assembly part 3D model is retrieved according to the assembly part 3D model number. If the process logistics information of the assembly part 3D model is consistent with the attribution information, the result information of successful logistics verification is output.

[0151] Since the shapes of actual assembly parts are not fixed, there are deformation parts and non-deformation parts in actual assembly parts, and there are also deformation parts 3D models and non-deformation parts 3D models in assembly parts 3D models.

[0152] Step S3 also includes:

[0153] S304, acquiring deformation information of the 3D model of the assembly part, and determining whether the assembly part is a deformable part based on the deformation information;

[0154] Specifically, deformation information of the 3D model of the assembly part is obtained, and based on the deformation information, it is determined whether the assembly part is a deformable part;

[0155] S305, if the 3D model of the assembly part is a deformable part, obtaining comprehensive attribution information based on the deformation information and the attribution information;

[0156] It should be noted that although the installation interface and position of the deformable part are fixed, due to its deformation characteristics, it is often connected to both the body and the engine. At the same time, the shape and layout of the body are directly related to the assembly environment. Logistics information verification requires a comprehensive judgment based on the assembly environment. If the 3D model of the assembly part is a deformable part, the comprehensive attribution information is obtained based on the deformation information and attribution information.

[0157] For example: Figure 4As shown, the assembly route of the bracket and the horn is the final assembly route. This is because the bracket and the horn and the final assembly body water pipe C are not only connected to the engine and the body at the same time, but also have the risk of interference with multiple environmental parts (engine body, bracket, water tank, etc.). If the water pipe C is installed in the engine factory, then when the engine is installed in the final assembly factory, the engine installation operation will be seriously affected due to the unfixed state of the deformable parts. Therefore, the manufacturing route of the water pipe C can only be the final assembly factory.

[0158] S306. Compare the comprehensive attribution information with the process logistics information to obtain logistics verification results.

[0159] Specifically, if the comprehensive attribution information is consistent with the process logistics information, the result information of successful logistics verification is output; if the comprehensive attribution information is inconsistent with the process logistics information, the result information of unsuccessful logistics verification is output.

[0160] In this embodiment, the comprehensive attribution information is compared with the process logistics information to obtain the logistics verification result, which can verify the part assembly environment, and the interference problem between the part body and the environment parts, the assembly environment restrictions and other states can be effectively verified;

[0161] At the same time, the assembly environment of the deformed parts can also be verified. For the variable state characteristics of the deformed parts, the mutual influence between the deformed parts and the assembly environment can be simulated to achieve the purpose of verifying the accuracy of the process logistics information of the deformed parts.

[0162] It should be noted that the step numbers of the steps in the embodiments of the present application do not limit the sequence of the operations in the technical solution of the present application.

[0163] Second, see Figure 1 As shown, an embodiment of the present application provides a material data verification device, which includes:

[0164] A structure verification module, which is used to obtain a structure verification result based on the interface structure information of the assembly part 3D model and the interface structure information of the actual assembly part;

[0165] A manufacturing verification module, which is used to obtain a manufacturing verification result based on the interface structure information of the assembly part 3D model and the interface structure information of the opponent part matching the assembly part 3D model;

[0167] An inspection module is used to obtain a material data verification result of the assembly part 3D model according to the structure verification result, the manufacturing verification result and the logistics verification result.

[0168] This application constructs a 3D model of assembly parts in a virtual environment based on the structure and size of actual assembly parts, and performs structural verification, manufacturing verification, and process logistics information verification on the 3D model of assembly parts in combination with the process logistics information, size information, and structural information of the actual assembly parts. This allows comprehensive verification of all business scenario data in the BOM, thereby improving the accuracy of vehicle-level BOM data verification.
