Description

Technical Field

[0001] The present invention relates to the field of vehicle technology, and in particular to a method, device, equipment, medium and product for generating a three-dimensional graphic structure tree. Background Art

[0002] In the process of body product design, the hierarchical design of parts and components, the same product unit contains several parts, the process design plan changes frequently, and the information such as material weight, material, cost, etc. must be output synchronously with the data plan to ensure the agility and accuracy of project development. Since product design does not strictly stipulate that the product structure tree is consistent with the details, it leads to serious rework of material verification, affecting process follow-up and increasing workload.

[0003] CATIA (Computer-Aided Three-Dimensional Interactive Application) software is a widely used 3D design and engineering analysis software in the industry. Although it has certain sorting functions, it can only adjust the order of a single node at a time. For large and complex assemblies like cars, this is obviously not enough to cope with the massive data processing needs. The vehicle assembly structure tree has many levels and tens of thousands of nodes. If you want to manually adjust the order of each node according to specific rules, it will not only be time-consuming, but also difficult to guarantee accuracy. It is easy to make omissions and errors, resulting in deviations in subsequent assembly and production work.

[0004] Related technology 1-"CN105243237B" discloses a method for constructing an assembly process structure tree, including (1) assembly structure management; (2) assembly process design, determining the assembly process route; (3) assembly process model construction, defining an empty process model component node, and completing the process attribute information, including process number, process name, assembly resources, and then adding the process model of the previous process and the supporting parts model of the current process to the newly created process model component node; (4) assembly path simulation; (5) three-dimensional process file output. This method mainly focuses on the definition, characteristics and construction method of the assembly process structure tree, aiming to achieve model-based assembly process information expression. However, its application scenarios are mainly concentrated in the assembly process of complex products. For the problem of inaccurate structure tree caused by the disordered arrangement order of parts in the body product design process, no targeted solution is given.

[0005] Related technology 2 - "CN114943011A" discloses a method and system for screening vehicle configuration data, the method comprising: obtaining the top-level parts of the CATIA product structure tree; wherein the CATIA product structure tree is obtained by loading the vehicle configuration data or assembly data through CATIA. Then, determine whether the top-level part has sub-parts, and if so, obtain the sub-part list of the top-level part. Finally, traverse each sub-part in the sub-part list to determine whether the sub-part is non-current configuration data. If so, delete the structure tree object corresponding to the sub-part, and reconstruct the CATIA product structure tree. This method mainly solves the problem of screening vehicle configuration data. By traversing the sub-parts of each node of the product structure tree, non-current configuration data is automatically removed to obtain accurate vehicle configuration information, but the accuracy of the structure tree is not considered from the order of parts arrangement. Summary of the invention

[0006] One of the purposes of the present invention is to provide a method for generating a three-dimensional graphic structure tree to solve the problems in the related art that the structure tree has low accuracy, is prone to problems in the subsequent management of parts in vehicle manufacturing, and has reduced subsequent work efficiency; a second purpose is to provide a device for generating a three-dimensional graphic structure tree; a third purpose is to provide an electronic device; a fourth purpose is to provide a computer-readable storage medium; a fifth purpose is to provide a computer program product; and a sixth purpose is to provide a vehicle.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0008] A method for generating a three-dimensional graphic structure tree comprises the following steps: identifying a current process of a vehicle manufacturing process, wherein the current process comprises a welding assembly and an assembly assembly; if the current process is a welding assembly, obtaining a result of a sequence sorting of parts of the welding assembly, and generating a three-dimensional graphic structure tree of the welding assembly according to the result of the sequence sorting of parts; if the current process is an assembly assembly, obtaining a result of a spatial distribution sorting of parts of the assembly assembly, and generating a three-dimensional graphic structure tree of the assembly assembly according to the result of the spatial distribution sorting of parts.

[0022] According to the above technical means, the embodiment of the present application can determine whether there is an overlapping area by detecting the distance between regular three-dimensional objects, thereby optimizing the spatial distribution of components.

[0056] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0057] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0058] Specifically, Figure 1 A schematic flow chart of a method for generating a three-dimensional graphic structure tree provided in an embodiment of the present application.

[0059] like Figure 1 As shown, the method for generating the three-dimensional graphic structure tree includes the following steps:

[0060] In step S101 , the current process of the vehicle manufacturing process is identified.

[0061] Among them, the current process includes welding assembly and assembly assembly. Welding assembly is to permanently connect two or more parts together, and assembly assembly refers to assembling multiple parts or components together.

[0062] In step S102, if the current process is a welding assembly, a result of the order sorting of components of the welding assembly is obtained, and a three-dimensional graphic structure tree of the welding assembly is generated according to the result of the order sorting of components.

[0063] It can be understood that in the embodiment of the present application, if the current process is a welding assembly, a three-dimensional graphic structure tree of the welding assembly is generated based on the component sequence sorting results of the welding assembly, so that subsequent operators can check the welding assembly based on the three-dimensional graphic structure tree of the welding assembly to improve subsequent work efficiency. The specific process is as follows.

[0064] In an embodiment of the present application, obtaining the order sorting result of the components of the welding assembly includes: obtaining the type and number of each component subset of the welding assembly; re-ordering each component subset according to the type and number of each component subset to obtain the order sorting result of the components of the welding assembly.

[0065] The types of the component subset include at least one of components, welding points and standard parts.

[0066] It can be understood that the welding assembly of the embodiment of the present application includes multiple components, and the type and number of each component subset are obtained, and each component subset is re-sorted in order according to the type and number of each component subset to obtain the component sequence sorting result of the welding assembly, so as to achieve a more standard and normative sorting of the components of the welding assembly.

[0067] The sorting in the embodiment of the present application is based on CATIA.

[0068] In an embodiment of the present application, each component subset is reordered according to the type and number of each component subset, including: reordering each component subset according to the type of each component subset; for each component subset of the same type, reordering according to the number length of each component subset.

[0069] Among them, the order can be sorted by bubble sorting. Figure 2 shown.

[0070] It is understandable that the embodiment of the present application can sort each component subset in sequence based on the type of the component subset, and for each component subset of the same type, since the component subsets are numbered differently, they are sorted in sequence according to the length of the number of each component subset.

[0071] It should be noted that, since the number of the component subset is not a number but a text, this application will use a function to convert the "single character" of each string into an ASC code and then compare it until a difference is found and exit.

[0072] For example, "5301130-FL01" and "5301130-FL01_WP" are looped with the shorter string length. If no difference is compared after the loop is completed, the longer string is placed after the shorter string.

[0073] In addition, this application finally sorts the special numbers and adjusts the order of sorting results.

[0074] In the embodiment of the present application, before reordering each component subset according to the type and number of each component subset, the method further includes: deleting all component subsets of the welding assembly.

[0075] Since CATIA sorting only supports single-node exchange sorting, it is difficult to achieve automation. Therefore, the embodiment of the present application can delete all component subsets of all welding assemblies to achieve subsequent re-sequencing.

[0076] In step S103, if the current process is assembly, the spatial distribution sorting result of the parts of the assembly is obtained, and a three-dimensional graphic structure tree of the assembly is generated according to the spatial distribution sorting result of the parts.

[0077] It can be understood that in the embodiment of the present application, if the current process is assembly, a three-dimensional graphic structure tree of the assembly is generated based on the spatial distribution sorting results of the parts of the assembly, so that subsequent operators can check the assembly based on the three-dimensional graphic structure tree of the assembly to improve subsequent work efficiency. The specific process is as follows.

[0078] In an embodiment of the present application, obtaining the spatial distribution sorting results of the components of the assembly includes: determining the spatial distribution of the components of the assembly; and generating the spatial distribution sorting results of the components according to the spatial distribution of the components and the standard parts of each component.

[0079] Among them, standard parts follow spare parts.

[0080] It is understandable that the embodiments of the present application can determine the spatial distribution of the components of the assembly, and generate a spatial distribution sorting result of the components based on the spatial distribution of the components and the standard parts of each component.

[0081] Specifically, the embodiment of the present application can abstract the parts into a rectangular box for simplified measurement, which can meet engineering needs and is highly efficient.

[0082] In an embodiment of the present application, before generating a component spatial distribution sorting result based on the component spatial distribution and the standard parts of each component, it also includes: setting a three-dimensional target reference for the component; simplifying each component into a regular three-dimensional object; and optimizing the component spatial distribution based on the distance between the regular three-dimensional object and the three-dimensional target reference.

[0083] Since CATIA software can provide measurement of the spacing between parts, but the position coordinates of the parts and the space occupied by the parts cannot be obtained, the embodiment of the present application sets the three-dimensional target reference of the parts in the part space (i.e., the rectangular box) as mentioned above, simplifies each part into a regular three-dimensional object, and optimizes the spatial distribution of the parts according to the distance between the regular three-dimensional object and the three-dimensional target reference.

[0084] Specifically, the space setting benchmarks are as follows: Figure 3 As shown, by using component 1 to calculate the distance between each reference, the front and back coordinates X- / X+, left and right coordinates Y- / Y+, and upper and lower coordinates Z- / Z+ of the part can be obtained.

[0085] That is: definition, L1 = distance (component 1, datum X-); L2 = distance (component 1, datum X+); L3 = distance (component 1, datum Y-); L4 = distance (component 1, datum Y+); L5 = distance (component 1, datum Z-); L6 = distance (component 1, datum Z+).

[0086] Then: X- = L1;

[0087] X+ = distance (reference X+, reference X-)-L2;

[0088] Y, Z and so on, we can get a region in the space where the part is located;

[0089] The areas occupied by all subsets in the assembly are calculated and cached in an array. Components and standard parts are distinguished by part number rules. The spatial sorting of components can be done in any direction of X, Y, or Z. Finally, the spatial distribution sorting results of the components are regenerated according to the adjusted order.

[0090] In an embodiment of the present application, the spatial distribution of components is optimized according to the distance between the regular three-dimensional object and the three-dimensional target reference, including: determining whether there is an overlapping area between adjacent components according to the distance between the regular three-dimensional object and the three-dimensional target reference, and if there is an overlapping area, optimizing the spatial distribution of components.

[0091] It is understandable that the embodiment of the present application can determine whether there is an overlapping area between adjacent components based on the distance between the three-dimensional object and the three-dimensional target reference. If there is an overlapping area, the spatial distribution of the components is optimized, as follows:

[0092] like Figure 4 As shown, to determine whether there is a spatial intersection (i.e., overlapping area) between components, take the spatial intersection between component 1 and component 2 as an example, the following formula can be used to determine:

[0093] 1. X2+>= X1-;

[0094] 2. X2-<= X1+;

[0095] 3. Y2+>= Y1-;

[0096] 4. Y2-<= Y1+;

[0097] 5. Z2+>= Z1-;

[0098] 6. Z2-<= Z1+.

[0099] If the above 6 items are met at the same time, component 1 and component 2 are bonded, otherwise component 1 and component 2 are not bonded.

[0100] The following is an example of a specific embodiment to illustrate the sequential sorting method involved in this application.

[0101] 1. Sorting by parts number sequence (used to sort the order of parts of welding assembly).

[0102] It is suitable for welding assembly, because it has fewer subsets, and the order of parts is applied in the normal order. Special parts are processed by identification. For any welding assembly, read the part numbers of all its subsets (parts + welding points + standard parts) to form an initial array, including assembly information, to form a text array, and sort the numbers using bubble sorting. The order of parts in the welding assembly before optimization is as follows Figure 5 As shown, the optimized sorting is as follows Figure 6 shown.

[0103] Since the part number is not a number but a text, the order of this application is as follows: Figure 7 As shown, each string is converted into an ASCII code using a function and then compared until a difference is found and the program exits.

[0104] If the length of each number is different, "5301130-FL01" and "5301130-FL01_WP", loop with the shorter string length; if no difference is compared after the loop, put the long string after the short string; finally, sort the special numbers and adjust the array order.

[0105] Since CATIA sorting only supports single-node exchange sorting, it is difficult to realize automation. Therefore, the reordering is achieved by deleting all subsets and re-sorting by array.

[0106] 2. Spatial distribution sorting of parts (also known as screw connection sorting, used to sort the spatial distribution of parts in an assembly).

[0107] It is suitable for screw connection sorting, because screw connections are composed of parts from different regions, with scattered spatial distribution, and each screw connection has a connection mark. The bill of materials often requires the mark to follow the specified installation parts, so this sorting will be more regular and convenient for subsequent material inspection. Figure 8 As shown, the optimized sorting is as follows Fig. 9 shown.

[0108] CATIA software can provide distance measurement between parts, but the position coordinates of the parts and the space occupied by the parts cannot be obtained. In addition, CATIA distance measurement is an object-oriented interface call, which has been verified to be extremely inefficient. This method abstracts the parts into a rectangular box for simplified measurement. After actual project implementation, it meets engineering needs and is extremely efficient. Figure 8 and Fig. 9 As shown, the three-dimensional space is simplified to two dimensions to describe its working principle. The process of spatial distribution sorting is as follows Fig.10 shown.

[0109] 1. Establish a benchmark in space;

[0110] 2. Use the parts to calculate the distance between each benchmark, and you can get the front and back coordinates X- / X+, left and right coordinates Y- / Y+, and up and down coordinates Z- / Z of the parts;

[0111] 3. Calculate the areas occupied by all subsets in the assembly, cache them in an array, distinguish parts from standard parts by part number rules, sort the parts in space in any direction of X, Y, or Z, and finally reassemble them in the adjusted order;

[0112] 4. The standard part follows the components by judging whether there is any intersection between the components: if component 1 and component 2 have a spatial intersection, then component 1 and component 2 fit together, otherwise component 1 and component 2 do not fit together.

[0113] 5. Obtain an ordered array and reassemble it to achieve sorting.

[0114] According to the method for generating a three-dimensional graphic structure tree proposed in the embodiment of the present application, it is possible to determine whether to sort the order of parts or the spatial distribution of parts based on the current process in the vehicle manufacturing process, to obtain the order sorting results of the parts of the welding assembly and the spatial distribution sorting results of the parts of the assembly, and to generate accurate three-dimensional graphic structure tree of the welding assembly and three-dimensional graphic structure tree of the assembly based on the order sorting results and the spatial distribution sorting results, respectively, so that subsequent operators can manage the parts based on the three-dimensional graphic structure tree, thereby improving subsequent work efficiency.

[0115] Next, a device for generating a three-dimensional graphic structure tree according to an embodiment of the present application will be described with reference to the accompanying drawings.

[0116] Fig.11 It is a block diagram of a device for generating a three-dimensional graphics structure tree according to an embodiment of the present application.

[0117] like Fig.11 As shown, the three-dimensional graphic structure tree generating device 10 includes: a recognition module 100, a first generating module 200 and a second generating module 300.

[0118] Among them, the identification module 100 is used to identify the current process of the vehicle manufacturing process, wherein the current process includes welding assembly and assembly assembly; the first generation module 200 is used to obtain the component sequence sorting result of the welding assembly if the current process is welding assembly, and generate a three-dimensional graphic structure tree of the welding assembly according to the component sequence sorting result; the second generation module 300 is used to obtain the component spatial distribution sorting result of the assembly assembly if the current process is assembly assembly, and generate a three-dimensional graphic structure tree of the assembly assembly according to the component spatial distribution sorting result.

[0119] In an embodiment of the present application, the first generation module 200 is further used to: obtain the type and number of each component subset of the welding assembly; re-order each component subset according to the type and number of each component subset to obtain the component ordering result of the welding assembly.

[0120] In the embodiment of the present application, the first generating module 200 is further used to: sequentially sort each component subset according to the type of each component subset; for each component subset of the same type, sequentially sort according to the number length of each component subset.

[0121] In the embodiment of the present application, the device 10 for generating the three-dimensional graphic structure tree in the embodiment of the present application further includes: a deletion module.

[0122] The deleting module is used to delete all component subsets of the welding assembly before reordering each component subset according to the type and number of each component subset.

[0123] In the embodiment of the present application, the type of the component subset includes at least one of a component, a welding point, and a standard part.

[0124] In the embodiment of the present application, the device 10 for generating the three-dimensional graphic structure tree in the embodiment of the present application further includes: an optimization module.

[0125] Among them, the optimization module is used to set the three-dimensional target reference of the parts before generating the parts spatial distribution sorting results according to the parts spatial distribution and the standard parts of each part; simplify each part into a regular three-dimensional object; and optimize the parts spatial distribution according to the distance between the regular three-dimensional object and the three-dimensional target reference.

[0126] In an embodiment of the present application, the optimization module is further used to determine whether there is an overlapping area between adjacent components based on the distance between the regular three-dimensional object and the three-dimensional target reference, and if there is an overlapping area, optimize the spatial distribution of the components.

[0127] It should be noted that the above explanation of the embodiment of the method for generating a three-dimensional graphic structure tree is also applicable to the device for generating a three-dimensional graphic structure tree of this embodiment, and will not be repeated here.
