Methods, devices, electronic equipment and storage media for locating weld seams on ship outer plating

Abstract

This invention discloses a method, apparatus, electronic device, and storage medium for locating weld bead on a ship's outer plating. Based on the ship's name identification diagram, the hull segment containing the ship's name is determined from the ship's section division diagram, resulting in multiple identified segments and their corresponding ship's name identification information. For each identified segment, the initial outer plating part containing the ship's name is determined based on the ship's name identification information. An outer plating part symmetrical to the initial outer plating part is used as a reference outer plating part. The part information of each initial outer plating part is modified according to the part information of the corresponding reference outer plating part to obtain a specific outer plating part. The weld bead outline corresponding to the ship's name is set on the specific outer plating part according to the ship's name identification information of the identified segment to which the reference outer plating part belongs. This replaces the original outer plating part, eliminating the need for manual marking, improving the accuracy of the weld bead outline, saving time spent by on-site workers on marking and stamping, shortening the ship construction cycle, and reducing labor costs.

Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a method, apparatus, electronic device, and storage medium for positioning weld seams on ship outer plates. Background Technology

[0002] The specifications provided by ship owners or customers usually require the ship's name, port of registry, and company name to be displayed on the port and starboard outer plating. Commonly used SPD modeling outer plating generation systems do not have the function of directly displaying various ship name markings on the outer plating. Some of these markings need to be welded onto the outer plating using steel plates, while others are handled by creating weld lines on the outer plating.

[0003] In existing technology, the outer plating parts are cut and assembled. The parts requiring processing are located, and a 1:1 paper pattern is printed on white paper. This pattern is then pasted in place, and a dot pattern is punched onto the outer plating to outline the ship's name insignia. Welding is then performed on this basis to form the insignia. Because the outer plating insignia involves many parts, and some insignia have curved edges, manual dot pattern making may lack accuracy. Furthermore, the time required for on-site workers to perform the dot pattern making is long, which not only extends the shipbuilding cycle but also increases labor costs. Summary of the Invention

[0004] This invention provides a method for locating weld seams on ship outer plates, which solves the problems of insufficient accuracy, long construction cycle, and high labor cost in the existing ship name marking processing method where workers mark and punch samples on site.

[0005] In a first aspect, the present invention provides a method for locating weld seams on the outer plating of a ship, wherein the outlines of symmetrical outer plating parts on the port and starboard sides of the ship are identical, and the ship name markings are horizontally reversed at symmetrical positions on the port and starboard sides. The method for locating weld seams on the outer plating of a ship includes:

[0006] Based on the ship name identification diagram, the hull section where the ship name mark is located is determined in the ship section division diagram, resulting in multiple marked sections and the ship name mark information of the marked sections;

[0007] For each of the marked segments, the initial outer plate part where the ship name mark is located in the marked segment is determined according to the ship name mark information;

[0008] The outer panel part symmetrical to the initial outer panel part is used as the reference outer panel part;

[0009] Modify the part information of each initial outer panel part according to the part information of the corresponding reference outer panel part to obtain a specific outer panel part. The part information includes part name and part structure.

[0010] According to the ship name marking information of the marked segment to which the reference outer plate part belongs, the weld outline of the ship name marking is set on the specific outer plate part.

[0011] The modified outer panel part is used to replace the original outer panel part with the same part name in the SPD system, so as to produce an outer panel part entity with the ship name mark based on the outer panel part in the SPD system.

[0012] In a second aspect, the present invention provides a positioning device for weld bead on a ship's outer plating, comprising:

[0014] The initial outer plate part determination module is used to determine the initial outer plate part where the ship name mark is located in each of the marked segments based on the ship name mark information;

[0015] The outer panel part determination module is used to determine an outer panel part that is symmetrical to the initial outer panel part as a reference outer panel part.

[0016] A specific outer panel part manufacturing module is used to modify the part information of each initial outer panel part according to the part information of the corresponding reference outer panel part to obtain a specific outer panel part. The part information includes part name and part structure.

[0017] The weld outline setting module is used to set the weld outline of the ship name mark on the specific outer plate part according to the ship name mark information of the marked segment to which the reference outer plate part belongs;

[0018] The inbound production module is used to replace the original outer panel parts with the same part name in the SPD system with the modified specific outer panel parts, so as to produce outer panel parts with ship name markings based on the outer panel parts in the SPD system.

[0019] Thirdly, the present invention provides an electronic device, the electronic device comprising:

[0020] At least one processor; and

[0021] A memory communicatively connected to the at least one processor; wherein,

[0022] The memory stores a computer program that can be executed by the at least one processor, which enables the at least one processor to perform the ship outer plate weld bead positioning method according to the first aspect of the present invention.

[0023] Fourthly, the present invention provides a computer-readable storage medium storing computer instructions that, when executed by a processor, implement the ship outer plate weld bead positioning method described in the first aspect of the present invention.

[0024] This invention provides a method for locating weld bead lines on a ship's outer plating. The outer plating parts symmetrically positioned on the port and starboard sides of the ship have identical outlines, and the ship's name markings are horizontally reversed at symmetrical positions on both sides. The method includes: determining the hull segment containing the ship's name markings based on the ship's name marking diagram in the ship's segmentation diagram, obtaining multiple marked segments and their corresponding ship's name marking information; for each marked segment, determining the initial outer plating part containing the ship's name markings based on the ship's name marking information; using an outer plating part symmetrical to the initial outer plating part as a reference outer plating part; modifying the part information of each initial outer plating part according to the part information of the corresponding reference outer plating part to obtain a specific outer plating part, the part information including part name and part structure; setting the weld bead outline of the ship's name markings on the specific outer plating part according to the ship's name marking information of the marked segment to which the reference outer plating part belongs; and replacing the original outer plating part with the same part name in the SPD system with the modified specific outer plating part to produce an outer plating part entity bearing the ship's name markings based on the outer plating parts in the SPD system. It enables CNC setting of weld contour lines, eliminating the need for manual marking, improving the accuracy of weld contours, saving time for on-site workers to mark and punch samples, shortening the shipbuilding cycle, and reducing labor costs.

[0037] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0038] Example 1

[0039] Figure 1 This is a flowchart of a method for locating weld seams on a ship's outer plating, provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of locating weld seams on a ship's outer plating. The method can be executed by a ship's outer plating weld seam positioning device, which can be implemented in hardware and / or software and can be configured in an electronic device.

[0040] like Figure 1 As shown, the method for positioning weld beads on the outer plate of this ship includes:

[0041] S101. Based on the ship name identification diagram, determine the hull section where the ship name mark is located in the ship section division diagram, and obtain multiple marked sections and ship name mark information of the marked sections.

[0042] The ship name marking diagram is a pre-provided diagram of the ship's name and port registration company's logo. This diagram is prepared by the shipbuilding company's hull processing and assembly department according to the signed specifications and confirmed by the shipowner. The ship name marking diagram usually indicates that the ship's name markings will be achieved by welding. The ship name markings are distributed on the port and starboard sides of the ship. The outlines of the symmetrical outer plating parts on the port and starboard sides of the ship are the same, and the ship name markings are set horizontally and in opposite directions at symmetrical positions on the port and starboard sides. Figure 2 This is a schematic diagram illustrating one method of placing a ship's nameplate on the port and starboard sides, such as... Figure 2 As shown, L1 is the centerline of the ship, and the arrow on L1 points towards the bow. Correspondingly, the opposite direction of the arrow points towards the stern. 201 is the port side, and 202 is the starboard side. The ship name signs are symmetrically positioned on the outer plating of the port and starboard sides. The horizontal arrangement of the ship name signs on the port side 201 is from bow to stern, while the horizontal arrangement on the starboard side 202 is from stern to bow. That is, the ship name signs are horizontally reversed at symmetrical positions on the port and starboard sides.

[0043] Figure 3 for Figure 2 A diagram showing the location of the ship's name markers on the starboard side, where 673-677 are the names of hull sections. Figure 4 for Figure 2 A diagram showing the location of the ship's nameplate on the port side, where 663-667 are the names of hull sections, such as... Figure 3 , Figure 4 As shown, the port hull sections 663-667 are symmetrical to the starboard hull sections 673-677. The outlines of the parts in the two symmetrical hull sections are the same, but the specific ship name markings (images and positions) in the hull sections are different.

[0044] Optionally, both the ship name identification diagram and the section division diagram include rib markings. The ship name identification diagram also includes ship name sign information. Based on the ship name identification diagram, the hull section where the ship name sign is located is determined in the ship's section division diagram, resulting in multiple marked sections and ship name sign information for the marked sections. This includes: determining the corresponding rib information based on the ship name sign information in the ship name identification diagram; determining the hull section used to mark the ship name sign in the ship's section division diagram with reference to the rib information, resulting in multiple marked sections; and dividing the ship name sign information according to the marked sections to obtain the ship name sign information for each marked section.

[0045] First, determine the rib marker where the ship name symbol is located based on the ship name identification diagram. Then, overlap the rib markers in the ship name identification diagram and the section division diagram to determine the hull section where the ship name symbol is located in the section division diagram. These hull sections are used as identification sections, and the ship name symbol information is assigned to the corresponding identification sections. For example... Figure 3 As shown, the ship's name is marked on hull sections 673-677, such as... Figure 4 As shown, the ship name is marked on hull sections 663-667, so hull sections 673-677 and 663-667 are both marked sections.

[0046] The ship nameplate diagram is essentially a specification document for manufacturing the ship nameplate. Therefore, the ship nameplate diagram includes ship nameplate information, specifically the image parameters and positional information of the ship nameplate. The image parameters of the ship nameplate are as follows: Figure 5 As shown, Figure 5 This is a schematic diagram of the image parameters for a ship name logo.

[0047] S102. For each marked segment, determine the initial outer plate part where the ship name mark is located in the marked segment based on the ship name mark information.

[0048] Generally speaking, hull sections are large-area ship plates, and each hull section is assembled from multiple outer plate parts. For example... Figure 3 , Figure 4 As shown, the ship name mark occupies only a portion of the area in each marking segment. Therefore, outer plate parts without the ship name mark in each marking segment do not require weld beads and do not need to undergo subsequent steps. However, outer plate parts with the ship name mark do require weld beads. The ship name mark information includes the location information of the ship name mark. Therefore, by using the ship name mark information, the outer plate parts containing the ship name mark in the marking segment can be determined, thus obtaining the initial outer plate parts.

[0049] Among them, the outer plating components of a ship can be generated in the Ship Product Design (SPD) system. Specifically, the names of each outer plating component are determined based on the ship's outer plating unfolding file; for each outer plating component, a description file for each component is defined in the SPD system, and the component is generated based on the description file and stored in the parts library.

[0050] It should be noted that before CNC blanking, any operations involving the design and modification of outer panel parts refer to the corresponding operations on the model files of the outer panel parts.

[0051] S103. Use the outer panel part that is symmetrical to the initial outer panel part as the reference outer panel part.

[0052] The outer plate parts are generated in the SPD system. For the SPD system, the generated part drawing automatically displays the component surface inside the hull, because the skeleton is connected inside the hull, while the weld is outside the hull. When processing the weld, it is equivalent to mirroring the outer plate parts to the back for processing. However, after mirroring, the weld outline (powder spraying line) of the ship name mark does not match.

[0053] To address this issue, in an optional embodiment of the present invention, for outer plate parts requiring weld powder coating, the port-side outer plate part (model) is modified to obtain a symmetrical starboard-side outer plate part, and the starboard-side outer plate part is modified to obtain a symmetrical port-side outer plate part. In this embodiment, the outlines and sizes of the two marked segments at symmetrical positions are the same, and the outlines and sizes of the two outer plate parts at symmetrical positions are also the same, thus allowing for corresponding modifications.

[0054] It should be noted that since the marked sections are symmetrically distributed on both sides of the port and starboard sides, the reference outer plating part is itself also the initial outer plating part, and the hull section where the reference outer plating part is located is also a marked section. For the initial outer plating part in the marked section on the port side, its reference outer plating part is the initial outer plating part in the marked section on the starboard side that is symmetrically positioned. For the initial outer plating part in the marked section on the starboard side, its reference outer plating part is the initial outer plating part in the marked section on the port side that is symmetrically positioned.

[0055] S104. Modify the part information of each initial outer panel part according to the part information of the corresponding reference outer panel part to obtain a specific outer panel part. The part information includes the part name and part structure.

[0056] The process of obtaining a specific outer panel part includes: for each initial outer panel part, modifying the part name of the initial outer panel part to the part name of the corresponding reference outer panel part, deleting part structures in the initial outer panel part that are different from the part structure of the corresponding reference outer panel part, and supplementing the part structure of the initial outer panel part according to the part structure of the corresponding reference outer panel part to obtain the specific outer panel part.

[0057] For example, such as Figure 3 , Figure 4 As shown, for the initial outer plating parts in section 663 on port side 201, the part name is taken from the part name in section 673 on starboard side 202. The original part name of a specific outer plating part in section 663 was "Port Side 663-A1", and after corresponding modification, the part name is "Starboard Side 673-A1". After modifying the part name, the specific outer plating part has the same part name as the reference outer plating part.

[0058] Specifically, the different part structures mainly include bevels, component markings connecting to the initial outer plate parts, and openings, while the part contours, part orientations, and machining allowances are usually the same and can be retained. S104 can be implemented using CAD.

[0059] S105. According to the ship name marking information of the marked section to which the reference outer plate part belongs, set the weld outline of the ship name marking on the specific outer plate part.

[0060] The ship's name marking needs to be achieved through welding, which means that a weld outline needs to be set on a specific outer plate part. The weld outline is the basis for subsequent welding.

[0061] Given that the ship name marking information for each marked segment is already obtained, for the current specific outer plate part, the weld outline of the ship name marking is set on the specific outer plate part according to the ship name marking information of the marked segment to which the outer plate part belongs. For example, combined with... Figure 3 , Figure 4 As shown, taking the initial outer plate part A1 in section 663 on the port side 201 as an example, it goes through the following stages:

[0062] Phase 1: The initial outer plating parts in section 663 on port side 201 are named "port side 663-A1", and the ship name markings in section 663 are all "N";

[0063] Second stage: After the part information is modified, it becomes a specific outer panel part and is named "Starboard 673-A1";

[0064] Phase 3: Using the ship name marking information on section 673 on starboard 202, the weld outline of the ship name marking is set accordingly, and all ship name markings in section 673 are "E".

[0065] Optionally, after setting the weld outline of the ship name mark on the specific outer plate part according to the ship name mark information of the marked segment to which the reference outer plate part belongs, the method further includes: adding weld powder spraying instruction text on each specific outer plate part. For example, the weld powder spraying instruction text is "Ship name weld powder spraying\reverse marking installation".

[0066] It's important to note that in the SPD system, specific colored lines are typically used to represent specific types of structural scribing. For example, in SPD, white lines represent the outer contour of a part, requiring cutting and must be closed curve segments. Cyan lines represent internal openings within the part, requiring closure and not connecting to the outer contour. Pink lines represent the scribing of components that connect to the part, including ribs, plates, or flat iron reinforcements. During cutting, the cutting machine scribing lines on the part using powder spraying serves as the basis for assembling connecting components after the part is cut. The side of the part that is normally displayed is the component side, i.e., the side with ribs connecting to it. Yellow lines represent direction and rib name markings on the part, manually added by the cutting team after the part is cut, referring to the nesting drawing. Therefore, when modifying information and structures in CAD, it is also necessary to use scribing lines of the corresponding colors to ensure the consistency and usability of information attributes in the model file.

[0067] S106. Replace the original outer panel parts with the same part name in the SPD system with modified specific outer panel parts, so as to produce outer panel parts entities with ship name markings based on the outer panel parts in the SPD system.

[0068] Modified outer panel parts can be manually imported into the SPD system's parts library. To avoid two outer panel parts with the same name existing in the SPD system's parts library, when manually importing a new outer panel part, the original outer panel part (model) with the same name is deleted from the SPD system. For example, if the imported outer panel part is "Starboard 673-A1", then the original "Starboard 673-A1" outer panel part should be deleted from the SPD system.

[0069] In the SPD system, referencing the structural drawing of a specific outer plate part (the part name has been modified at this point), bevels are defined around the perimeter of each outer plate part, with the bevels reversed from the structural drawing. Specifically, for each specific outer plate part in the SPD system, the bevel structure and bevel direction of the reference outer plate part corresponding to the specific outer plate part are determined; a bevel with the same bevel structure but opposite bevel direction is set for the specific outer plate part. Furthermore, the part information of new outer plate parts can be structurally adjusted, including information such as ship name, weld powder coating, part direction, and bevel.

[0070] Based on the outer panel parts in the SPD system, produce physical outer panel parts with ship name markings, specifically as follows:

[0071] a) Nest all processed outer panel parts and generate cutting diagrams and cutting instructions for use in the next process.

[0072] b) The cutting team uses the provided cutting diagram and instructions to cut out the outer panel parts with weld powder coating.

[0073] c) The employees in the inner assembly area assemble the outer panel parts (usually flat outer panels) and weld them according to the powder coating positions, specifically as follows: Figure 6 As shown, Figure 6 This is a photograph of a welded surface forming process for an outer panel component.

[0074] d) After the weld bead is formed, apply white paint as required.

[0075] This invention provides a method for locating weld bead lines on a ship's outer plating. The outer plating parts symmetrically positioned on the port and starboard sides of the ship have identical outlines, and the ship's name markings are horizontally reversed at symmetrical positions on both sides. The method includes: determining the hull segment containing the ship's name markings based on the ship's name marking diagram in the ship's segmentation diagram, obtaining multiple marked segments and their corresponding ship's name marking information; for each marked segment, determining the initial outer plating part containing the ship's name markings based on the ship's name marking information; using an outer plating part symmetrical to the initial outer plating part as a reference outer plating part; modifying the part information of each initial outer plating part according to the part information of the corresponding reference outer plating part to obtain a specific outer plating part, the part information including part name and part structure; setting the weld bead outline of the ship's name markings on the specific outer plating part according to the ship's name marking information of the marked segment to which the reference outer plating part belongs; and replacing the original outer plating part with the same part name in the SPD system with the modified specific outer plating part to produce an outer plating part entity bearing the ship's name markings based on the outer plating parts in the SPD system. It enables CNC setting of weld contour lines, eliminating the need for manual marking, improving the accuracy of weld contours, saving time for on-site workers to mark and punch samples, shortening the shipbuilding cycle, and reducing labor costs.

[0076] Example 2

[0077] Figure 7 This is a flowchart of a method for locating weld beads on a ship's outer plate according to Embodiment 2 of the present invention. This embodiment of the present invention is an optimization based on Embodiment 1 described above, such as... Figure 7 As shown, the method for positioning weld beads on the outer plate of this ship includes:

[0078] S701. Based on the ship name identification diagram, determine the hull section where the ship name mark is located in the ship section division diagram, and obtain multiple marked sections and ship name mark information of the marked sections.

[0079] S702. For each marked segment, determine the initial outer plate part where the ship name mark is located in the marked segment based on the ship name mark information.

[0080] S703, Use the outer panel part that is symmetrical to the initial outer panel part as the reference outer panel part.

[0081] S704. Modify the part information of each initial outer panel part according to the part information of the corresponding reference outer panel part to obtain a specific outer panel part. The part information includes the part name and part structure.

[0082] S701-S704 are similar to S101-S104 in Embodiment 1, and can be found in the relevant description in Embodiment 1.

[0083] Optionally, the ship name marking information also includes a waterline height range. For each marking segment, the initial outer plate part where the ship name marking is located in the marking segment is determined based on the ship name marking information, including: determining the waterline height range of the ship name marking based on the ship name marking information; in each marking segment, extracting the area where the height of the distance from the baseline of the rib marking is within the waterline height range as the area to be processed; and using the outer plate part in the area to be processed as the initial outer plate part where the ship name marking is located in the marking segment.

[0084] S705. The splice of a specific outer panel part in the same marked segment is taken as a part block, and the splice of a reference outer panel part in the same marked segment is taken as a reference block.

[0085] S706. For each part block, according to the ship name mark information of the corresponding reference block to which the mark segment belongs, set the weld outline of the ship name mark on the part block to obtain the modified part block.

[0086] Each original part block contains a significant amount of structural information. Part structures that differ from the reference block can be deleted, including pink structural lines within the original part outline, profile names, bevels, etc., while retaining the outline, orientation, and machining allowance information, resulting in... Figure 8 The shown component blocks, Figure 8 This is a schematic diagram showing the assembly of specific outer panel parts within the same segmented designation, along with their corresponding ship name markings. The part names of the specific outer panel parts involved in the assembly are 675-K1, 675-K2, and 675-K3. The corresponding ship name marking information is determined and drawn within the part assembly, resulting in the drawn part assembly. The drawn ship name markings are shown below. Figure 8 As shown.

[0087] Generally speaking, within the same marking section, the outer plate parts where the ship's name mark is located are connected.

[0088] In this embodiment, the splice of specific outer plate parts in the same marked segment is taken as part blocks, and the weld outline of the ship name mark is set in the form of blocks. By merging multiple specific outer plate parts, the efficiency of setting the weld outline can be improved. For the operation of setting the outline separately, there may be different design accuracy errors. The merging process can avoid different design accuracy errors and improve design accuracy.

[0089] S707. Disassemble the specific outer panel part in the modified part block to obtain the modified specific outer panel part.

[0090] S708. Replace the original outer panel parts with the same part name in the SPD system with modified specific outer panel parts, so as to produce outer panel parts entities with ship name markings based on the outer panel parts in the SPD system.

[0091] S708 is similar to S106 in Embodiment 1, and you can refer to the relevant description in Embodiment 1 for details.

[0092] In this embodiment, the splice of specific outer plate parts in the same marked segment is taken as part blocks, and the weld outline of the ship name mark is set in the form of blocks. By merging multiple specific outer plate parts, the efficiency of setting the weld outline can be improved. For the operation of setting the outline separately, there may be different design accuracy errors. The merging process can avoid different design accuracy errors and improve design accuracy.
