Moreover, due to the humanization of the task operation, the welding efficiency of components is low, the quality is poor, and the welding quality fluctuates greatly, which seriously restricts the output of ship hull component welding.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] An automatic welding method for ship hull components includes the following steps:

[0009] S4: Based on the first weld data, complete the automatic welding of the first weld of the component;

[0010] S5: Scan the barcode again to check if there is a secondary weld seam in the component that needs to be delayed for welding; if there is no secondary weld seam, report the work separately; if there is a secondary weld seam, perform delayed welding on the component according to the secondary weld seam data of the component and report the work separately.

[0011] As a preferred embodiment of the present invention, in step S3, the method for obtaining the primary weld data is as follows: based on the three-dimensional model, the component structure relationship is formed, and the primary weld data is generated.

[0012] As a preferred embodiment of the present invention, in step S4, the welding method of the primary weld of the component is as follows: based on the primary weld data, the optimal welding process is obtained by matching with an external process library, and the primary weld of the component is welded by an external automatic welding equipment.

[0013] As a preferred embodiment of the present invention, in step S5, the welding method of the secondary weld of the component is as follows: based on the secondary weld data, the optimal welding process is obtained by matching with an external process library, and the secondary weld of the component is slowly welded by an external automatic welding equipment.

[0014] As a preferred embodiment of the present invention, in step S5, the method of sorting and reporting is as follows: according to the barcode, match the subsequent process of the component, set the storage area of ​​the component, and obtain the component's entry data.

[0015] As a preferred embodiment of the present invention, the barcode is a barcode or a QR code.

[0016] The automatic welding method for ship hull components provided by this invention has the following advantages compared with the prior art:

[0017] In operation, this invention uses barcodes with component identification numbers to categorize and manage components, facilitating rapid identification and tracking of the welding status of parts within each component. By scanning a 3D component and analyzing its 3D model, comprehensive primary weld data can be obtained, enabling automated welding of the primary weld. This satisfies the requirements of digital production for ship component welding without demanding highly skilled operators, offering advantages such as low cost, high efficiency, and wide applicability. After the automated welding of the primary weld is completed, scanning the component's barcode again reveals any secondary welds requiring delayed welding. Based on the actual situation, these secondary welds can be delayed, ensuring the orderly progress of ship component welding. Attached Figure Description

[0018] To more clearly illustrate the technical solutions of the embodiments of the present invention, the accompanying drawings of the embodiments will be briefly described below.

[0019] Figure 1 This is a flowchart of an automatic welding method for ship hull components provided in an embodiment of the present invention. Detailed Implementation

[0020] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0021] In the description of this invention, it should be understood that the terms "upper," "lower," "left," "right," "front," "rear," "top," and "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. It should be understood that the terms "first," "second," etc., are used in this invention to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this invention, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.

[0022] like Figure 1 As shown, a preferred embodiment of the present invention provides an automatic welding method for ship hull components, which includes the following steps:

[0023] S1: Set a barcode for the component, the barcode containing the component's serial number. In this embodiment, the barcode is preferably a barcode or a QR code.

[0024] S2: Scan the barcode and perform a 3D scan of the component to generate a 3D model of the component;

[0025] S3: Based on the three-dimensional model, obtain the primary weld data of the component;

[0026] S4: Based on the first weld data, complete the automatic welding of the first weld of the component;

[0027] S5: Scan the barcode again to check if the component has a secondary weld that needs to be delayed for welding; if there is no secondary weld, report the component for work; if there is a secondary weld, perform delayed welding on the component based on the secondary weld data, and then report the component for work. The method for reporting the component for work is as follows: based on the barcode, match the subsequent processes of the component, set the storage area for the component, and obtain the component's pallet entry data.

[0028] According to the automatic welding method for ship hull components of the present invention, during operation, the components can be classified and managed by setting barcodes with component number data, facilitating the rapid identification and tracking of the welding status of parts within the components (e.g., the delayed welding zone reserved for deformation space to eliminate subsequent welding stress, i.e., the secondary weld mentioned above). By scanning the three-dimensional component and analyzing its three-dimensional model, the primary weld data of the component can be comprehensively obtained, and the automatic welding of the primary weld of the component can be completed. This not only meets the requirements of digital production for ship hull component welding, but also does not require operators to have high professional skills, and has the characteristics of low cost, high efficiency, and strong applicability. After the automatic welding of the primary weld of the component is completed, by scanning the component's barcode again, it is possible to check whether there are secondary welds to be delayed for welding, and the secondary welds can be delayed for welding according to the actual situation, ensuring the orderly progress of ship hull component welding work.

[0029] For example, in step S3, the method for obtaining the primary weld data is as follows: based on the three-dimensional model, the component's structural relationship is formed, and the primary weld data is generated. Therefore, the operator can quickly and accurately obtain the primary weld data of the component, making the operation easy to understand and highly digitized.

[0030] In step S4, the welding method for the primary weld of the component is as follows: based on the primary weld data, the optimal welding process is obtained by matching with an external process library, and the primary weld of the component is welded using external automatic welding equipment. In step S5, the welding method for the secondary weld of the component is as follows: based on the secondary weld data, the optimal welding process is obtained by matching with an external process library, and the secondary weld of the component is slowly welded using external automatic welding equipment. Therefore, by using primary and secondary weld data and obtaining the optimal welding process by matching with an external process library, the welding efficiency and quality of the component can be accurately improved. This method is highly automated and avoids limiting the output of ship hull component welding due to large fluctuations in the welding quality of the component.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
