DETAILED DESCRIPTION

[0059] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0060] First, let’s explain the terms involved in this application:

[0061] Geometric parameters are used to describe the shape of a single structure in a 3D model. Specifically, this shape can include a single parameter or a combination of multiple parameters. Exemplary geometric parameters include plate thickness, tube outer diameter, groove angle, blunt edge, and weld length. Plate thickness can be represented by T, tube outer diameter by D, groove angle by A, blunt edge by C, and weld length by L.

[0062] The preset rule information is an algorithm rule for processing geometric parameters. Specifically, the preset rule information is set in advance.

[0063] The position to be welded refers to the connection position between single-piece structures in the three-dimensional model. There can be multiple welding methods for the position to be welded. For example, the method can be a butt weld, a fillet weld, a single-sided combination weld, and a double-sided combination weld.

[0064] Weld symbols are used to describe data information about weld locations. For example, weld symbols include weld grade, weld serial number, and endnotes.

[0065] The trigger operation is the user's operation on the three-dimensional model. The operation can be preset by the user. For example, the operation can be double-clicking the position to be welded, or single-clicking the position to be welded, or any operation that can cause the computer device to respond.

[0066] The specific application scenario of this application is to mark the weld symbols of the welding positions in the three-dimensional model in the Cero online design platform. Currently, the welding positions are marked manually, and manual annotation will cause a large workload and prone to errors.

[0067] The method for marking weld positions provided in this application is intended to solve the above technical problems in the prior art.

[0068] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0069] Figure 1 : This is a flow chart of a method for marking weld positions according to the first embodiment of the present application. Specifically, the first embodiment includes the following steps:

[0070] S110 , acquiring a structure in a three-dimensional model, and identifying geometric parameters of at least one single structure in the structure.

[0071] In this embodiment, a structure is obtained from a 3D model on the Cero online design platform. Specifically, the structure may be composed of at least one single-piece structure. When obtaining the single-piece structure from the 3D model, the parameters can be obtained sequentially based on each edge of the single-piece structure, thereby obtaining the three-dimensional geometric parameters of the single-piece structure. Exemplarily, the geometric parameters of the single-piece structure may be: T14, D / , A45, C1, L2790, T14, D / , A45, C1, L2580, T14, D / , A45, C2, L98, T14, D / , A30, C2, L2790. D / indicates that the single-piece structure does not have a tube outer diameter. Furthermore, the plate thickness of the first edge of the single-piece structure is 14 cm, the tube outer diameter is absent, the single-piece groove angle is 45 degrees, the blunt edge is 1 cm, and the weld length is 2790 cm.

[0072] If the geometric parameters of two single-piece structures are obtained, they are divided by *. For example, T14, D / , A45, C1, L2790, T14, D / , A45, C1, L2580, T14, D / , A45, C2, L98, T14, D / , A30, C2, L2790, *T14, D / , A30, C2, L271, T14, D / , A50, C2, L150, T14, D / , A22.5, C1, L100.

[0073] S120 : Determine a weld symbol of a to-be-welded position of at least one single structure according to preset rule information and geometric parameters.

[0074] In this embodiment, the geometric parameters of at least one single structure are combined with the preset rule information, and the above-mentioned geometric parameters are processed according to the preset rule information to obtain the weld symbol. The above-mentioned data processing process is performed on each position to be welded, and finally the weld symbol of each position to be welded is determined.

[0075] S130 , in response to a triggering operation of the position to be welded, marking a weld symbol on the position to be welded in the three-dimensional model.

[0076] In this embodiment, when a user triggers a welding position, a weld symbol is automatically annotated at the welding position. For example, if welding position A is composed of the connection between a single structure A and a single structure B, and the triggering operation is to double-click the welding position, then when the double-click operation is received, a weld symbol is annotated at welding position A in the 3D model. The weld symbol is a uniquely identified symbol generated for welding position A.

[0077] This application provides a method, device, equipment, storage medium, and product for marking weld locations. These methods obtain a three-dimensional model of a product, identify the geometric parameters of each individual structure in the three-dimensional model, and combine these geometric parameters with pre-set rule information to determine the welding symbols for the locations to be welded between the individual structures. Upon receiving a triggering operation for a location to be welded, the weld symbols are automatically marked at the locations to be welded in the three-dimensional model. This technical solution enables the automatic and accurate marking of weld locations, thereby avoiding extensive manual work, saving time, and improving marking accuracy.

[0078] Figure 2 This is a flow chart of a method for marking weld positions according to the second embodiment of the present application. Specifically, the second embodiment includes the following steps:

[0079] S210: Establish a mapping relationship between a geometric parameter and at least one weld parameter, and form preset rule information according to the mapping relationship.

[0080] In this embodiment, a mapping relationship between the geometric parameters and the at least one weld parameter is established based on the geometric parameters, at least one weld parameter, and a preset calculation method. Specifically, at least one weld parameter is obtained from a weld rule library; the weld parameters include weld type, weld label, and weld number; and a mapping relationship between the geometric parameters and the at least one weld parameter is established according to weld index requirements.

[0081] Furthermore, weld types include butt welds, fillet welds, single-sided combination welds, and double-sided combination welds. Specifically, the weld labels of butt welds can be V, Y, U, I, HV, HY, and J; wherein V represents a V-type weld, Y represents a Y-type weld, U represents a U-type weld, I represents an I-type weld, HV represents an HV-type weld, HY represents a HY-type weld, and J represents a J-type weld. The weld symbols of a single-sided combination weld can be HV+a and HY+a, and the weld symbols of a double-sided combination weld are HV+a / HV and HV+a / HV+a. Weld numbers mainly refer to the numbers of various specific symbols.

[0082] Furthermore, the weld parameters also include: auxiliary symbol parameters, weld surface treatment symbols, concave surface, convex surface, flat weld, flat ground, ground weld toe, welding path symbol, circumferential weld O, intermittent weld, arrow, pointing to the upper edge of the blunt edge of the groove on one side, pointing to the intersection line of two component parts, pointing to the upper edge of the blunt edge of the groove on one side, pointing to the upper edge of the blunt edge of the groove on one side and reference line.

[0083] For more information about the preset rules, see Figure 3 , Figure 3 Shown is a preset rule for a weld seam.

[0084] S220: Acquire a structure in a three-dimensional model, and identify geometric parameters of at least one single structure in the structure.

[0085] S230: Use the geometric parameters as input values ​​of preset rule information.

[0086] In this embodiment, illustratively, the geometric parameters are T1, A1, C1, T2, A2, and C2, and the above geometric parameters are input into the preset rules.

[0087] S240: Calculate the output value based on the input value according to the calculation method in the preset rule information.

[0088] In this embodiment, according to the calculation method C≤1 and A1+A2=50-60 in the preset rule, a V-shaped weld is obtained as a derivation result, and the weld angle value is x=min(T1, T2).

[0089] S250: Use the output value as a weld symbol of a to-be-welded position of at least one single structure.

[0090] In this embodiment, V and x=min(T1, T2) are used as the weld symbol of the position to be welded. The advantage of this setting is that the weld symbol can be intelligently generated according to the geometric parameters, and the weld symbol can be quickly marked.

[0091] S260: In response to a triggering operation of the position to be welded, a weld symbol is marked on the position to be welded in the three-dimensional model.

[0092] In this embodiment, if a trigger operation of the position to be welded is received, illustratively, when the trigger operation is a double-click operation, the weld symbol V and x=min(T1, T2) are marked on the position to be welded in the three-dimensional model.

[0093] Figure 4 : This is a flow chart of a method for marking weld positions according to the third embodiment of the present application. Specifically, the third embodiment includes the following steps:

[0094] S410: Acquire a structure in a three-dimensional model, and identify geometric parameters of at least one single structure in the structure.

[0095] S420: Determine a weld symbol of a to-be-welded position of at least one single structure according to preset rule information and geometric parameters.

[0096] S430: In response to a triggering operation of the position to be welded, a weld symbol is marked on the position to be welded in the three-dimensional model.

[0097] S440. Display the marking results of the weld symbols of the positions to be welded for the user to view.

[0098] In this embodiment, the marking results of the welding position can be found in Figure 5 A schematic diagram of a weld symbol annotation result is shown in FIG. The annotation result can be displayed to the user, and the geometric parameters of the annotation result can be displayed in a variable text in the custom drawing symbol.

[0099] S450: Generate a process file of the annotation results based on the annotation results.

[0100] In this embodiment, the process file of the marking result is generated as an XML (Extensible Markup Language) file and stored in the storage system. Figure 6 A schematic diagram of an XML file is shown in FIG.

[0101] S460: If the marking result does not meet the preset conditions, the data information in the process file is obtained.

[0102] In this embodiment, the preset condition can be the serial number at the end of the marking result. For example, if there is no serial number at the end of the marking result or the serial number does not correspond, it means that the marking result does not meet the preset conditions, which will cause the weld grade in the output marking result to not correspond. Specifically, the order of the serial numbers at the end is N2 / CPB / UT / G1 / 20, and the end of the marking result must be marked according to this serial number, and the end of the double-sided weld marking result needs to be marked with two serial numbers, otherwise the output result will be incomplete. Furthermore, the " / " symbol in the marking result can be used to distinguish the weld grade and serial number.

[0103] S470: Determine error information of the marking result based on the data information.

[0104] In this embodiment, the error message of the problem is confirmed by checking the data information in the process file, and then modified so that the annotation result meets the preset conditions and is displayed normally. The advantage of this setting is that when a problem occurs in the annotation result, the problem can be quickly and accurately determined.
