[0037] According to an embodiment of the present invention, a welding production system embodiment is provided.

Although the system described in the following embodiments is preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceivable.

[0038] Figure 1 Schematic diagram of the structure of a welding production system according to an embodiment of the present invention. Figure 1 As shown, a welding production system provided in an embodiment of the present invention includes:

[0039] An input terminal module 11 , a welding determination module 12 and an execution module 13 . The welding determination module 12 comprises an information determination module 121 and a process determination module 122 connected to the information determination module 121 .

[0040] The input terminal module 11 is connected to the information determination module 121 .

[0041] The input end module 11 is configured to determine the three-dimensional model corresponding to the target component according to the model image of the top and bottom frames to be welded or the custom size of the top and bottom frames to be welded, and send the three-dimensional model corresponding to the target component to the information determination module 121. The target component includes a main beam component, a secondary beam component and a reinforcing rib component. The three-dimensional model corresponding to the target component includes a main beam three-dimensional model corresponding to the main beam component, a secondary beam three-dimensional model corresponding to the secondary beam component and a reinforcing rib three-dimensional model corresponding to the reinforcing rib component.

[0042] The information determination module 121 is connected to the process determination module 122 .

[0043] The information determination module 121 is configured to determine the target information according to the three-dimensional model corresponding to the target component. The target information is sent to the process determination module 122. The target information includes the size information, quantity information, position information and relative position information between the target components of the target component, as well as the welding position determined according to the size information, quantity information, position information and relative position information between the target components of the target component and the welding information corresponding to the welding position. The welding information includes welding category, interface type and welding length. The size information of the target component includes length, width and height.

[0044] The process determination module 122 is connected to the execution module 13 .

[0045] The process determination module 122 is configured to determine the placement process corresponding to the target component and the welding process corresponding to the welding position according to the target information, and send the placement process corresponding to the target component and the welding process corresponding to the welding position to the execution module 13 .

[0046] The execution module 13 is configured to execute the placement process corresponding to the target component and the welding process corresponding to the welding position.

[0047] In order to improve the accuracy of the component welding process and optimize the processing efficiency of the entire process, the present invention provides a welding production system, wherein the input end module 11 can quickly parse the non-parameter drawings, the welding determination module 12 can obtain the process information of the component processing nodes (such as placement nodes and welding nodes), and the execution module 13 can perform processing and production according to the placement process and welding process determined by the welding determination module 12.

[0048] In this embodiment, the model image of the top and bottom frames to be welded includes a two-dimensional image and a three-dimensional image. As an example, the two-dimensional image may be a DWG two-dimensional drawing file, and the three-dimensional image may be an IFC three-dimensional model file.

[0049] In this embodiment, the input module 11 determines the three-dimensional model corresponding to the target component in three ways, such as: Figure 2 As shown, the first type: custom mode, the input end module 11 includes a UI interface, custom modeling is performed on the top and bottom frames to be welded, and the custom size and other data of the top and bottom frames to be welded are input in the UI interface to generate a three-dimensional model of the main beam, a three-dimensional model of the secondary beam, and a three-dimensional model of the reinforcement. For the above scheme, the input end module 11 can be configured to input the custom size of the top and bottom frames to be welded into the UI interface, and generate a three-dimensional model corresponding to the target component according to the custom size of the top and bottom frames to be welded.

[0050] As an example, the custom mode specifically includes: the custom component function supports the creation of a workpiece of the "standard chassis" type. The user needs to open the custom component interface, that is, the UI interface included in the input end module 11, and enter the "workpiece name", "workpiece quantity", "frame size", "main beam cross section", "secondary beam cross section", "number of secondary beams", "secondary beam spacing", "distance from the first secondary beam to the end of the main beam", "distance from the reference plane to the end of the main beam", "distance from the top of the main and secondary beams", "platform screw adjustment height" and other information in the basic information of the UI interface. If there are ribs on the workpiece, it is necessary to enter the "number of rib rows", "rib cross section", "rib position from the upper end of the main beam", "rib vertical distance from the bottom of the secondary beam" and other information in the rib information. Then, after obtaining the above key information, the relevant software will automatically perform three-dimensional modeling to generate a three-dimensional model of the main beam, a three-dimensional model of the secondary beam and a three-dimensional model of the rib.

[0051] The second type: when the model image of the top frame to be welded is a three-dimensional image, such as an IFC three-dimensional model file, the main beam three-dimensional model, the secondary beam three-dimensional model and the reinforcing rib three-dimensional model are directly determined by reading the IFC three-dimensional model file. For the above scheme, the input end module 11 can be configured to select the files corresponding to all the main beam components in the three-dimensional model file of the top frame to be welded, change the names of all the files corresponding to the main beam components, and add a first suffix, such as "-Beam". Select the files corresponding to all the secondary beam components in the three-dimensional model file of the top frame to be welded, change the names of all the files corresponding to the secondary beam components, and add a second suffix, such as "-Sec". Select the files corresponding to all the reinforcing rib components in the three-dimensional model file of the top frame to be welded, change the names of all the files corresponding to the reinforcing rib components, and add a third suffix, such as "-Rein". The input end module 11 can be configured to generate the three-dimensional model corresponding to the main beam component according to the files corresponding to all the main beam components, generate the three-dimensional model corresponding to the secondary beam component according to the files corresponding to all the secondary beam components, and generate the three-dimensional model corresponding to the reinforcing rib component according to the files corresponding to all the reinforcing rib components.

[0052] As an example, reading the IFC 3D model file specifically includes: the user needs to modify the component suffix in the following way in the relevant software that supports .ifc output before outputting the 3D model corresponding to the target component: 1) Select all main beam components, change the name and add the suffix "-Beam". 2) Select all secondary beam components, change the name and add the suffix "-Sec". 3) Select all stiffener components, change the name and add the suffix "-Rein". After completion, export the file in IFC format, and then import the file on the relevant software end. The relevant software will automatically search and classify according to the suffix-related name to complete the export of the 3D model.

[0053] The third type: when the model image of the top and bottom frames to be welded is a two-dimensional image, such as a DWG two-dimensional drawing file (CAD file), the size information of the component is obtained by reading the DWG two-dimensional drawing file, and then the main beam three-dimensional model, the secondary beam three-dimensional model and the reinforcement rib three-dimensional model are automatically generated according to the size information of the component. For the above scheme, the input end module 11 can be configured to identify the two-dimensional drawing file of the top and bottom frames to be welded, obtain the main beam front view and side view, select the line segments in the main beam front view and side view, modify the layer information of the layer where the line segments in the main beam front view and side view are located (the layer information includes the name of the layer and the vector information of the line segments in the layer), and automatically determine the size information, quantity information and position information of the main beam component according to the layer information of the layer where the line segments in the main beam front view and side view are located after modification. Generate the main beam three-dimensional model corresponding to the main beam component according to the above data. The generation method of the secondary beam three-dimensional model and the reinforcement rib three-dimensional model is the same as the generation method of the main beam three-dimensional model, which will not be repeated here. The name of the layer is used to distinguish the type of component, and the names of the layers corresponding to the main beam component, the secondary beam component and the reinforcement rib component are different.

[0054] As an example, reading a DWG two-dimensional drawing file specifically includes: the user needs to adjust the drawing in the following manner before outputting the two-dimensional plan view of the top and bottom frames in the relevant software that supports .dwg output. Open the two-dimensional drawing standard file template .dwg, import the plan view and side view of the top and bottom frames, and then select the line segments of "plane main beam", "plane secondary beam", "plane reinforcement rib", "section main beam", "section secondary beam", and "section reinforcement rib" in the drawing in turn according to the specific classification, and modify their layer information to make it correspond to the layer of this type in the template file (the name is the same as the above content). Then import the file into the relevant software, and the relevant software will automatically classify according to the layer name, and then automatically calculate the length, width, height, quantity, position and other information about the main beam, secondary beam, and reinforcement rib according to the vector information of the layer, and then automatically perform three-dimensional modeling to generate a three-dimensional model of the main beam, a three-dimensional model of the secondary beam, and a three-dimensional model of the reinforcement rib. The plan view and side view of the top and bottom frames include the front view and side view of the main beam, the front view and side view of the secondary beam, and the front view and side view of the reinforcement rib.

[0055] In this embodiment, DWG (AutoCAD file format) and IFC (BIM format) files can be directly read through the input module 11. According to the internally formulated layer recognition algorithm and geometry algorithm, the input module 11 can automatically parse the two-dimensional and three-dimensional graphic content, extract the required geometric features and key process dimensions, and provide detailed welding parameters for the process determination module 122, which is helpful to formulate accurate welding processes.

[0056] In an optional embodiment, the information determination module 121 is further configured to determine whether the custom size of the top and bottom frames to be welded meets a preset range if the three-dimensional model corresponding to the target component is determined according to the custom size of the top and bottom frames to be welded. Wherein, when the custom size of the top and bottom frames to be welded meets the preset range, the three-dimensional model corresponding to the target component determined according to the custom size of the top and bottom frames to be welded is sent to the information determination module 121. When the custom size of the top and bottom frames to be welded does not meet the preset range, a prompt message is generated. The prompt message is used to remind the user that the custom size of the top and bottom frames to be welded does not meet the preset range, and the prompt message may include specific size data in the custom size of the top and bottom frames to be welded that does not meet the preset range, for example, the height of the main beam.

[0057] In this embodiment, the above-mentioned function of the information determination module 121 can be realized by a built-in error prevention module, that is, the built-in error prevention module in the information determination module 121 is configured to determine whether the custom size of the top and bottom frames to be welded meets the preset range if the three-dimensional model corresponding to the target component is determined according to the custom size of the top and bottom frames to be welded. In this embodiment, the information determination module 121 can also perform a secondary inspection and review on the input custom size of the top and bottom frames to be welded, and perform a compatibility review. Once the custom size of the top and bottom frames to be welded does not meet the preset range, an error message and prompt information will be generated.

[0058] In this embodiment, the information determination module 121 can also be configured to determine whether the target information meets a preset range after determining the target information according to the three-dimensional model corresponding to the target component. When the target information meets the preset range, the target information is sent to the process determination module 122. When the target information does not meet the preset range, a prompt message is generated.

[0059] In this embodiment, when a component is imported or a component size is customized, the component size must be within a processable range. In this embodiment, the above-mentioned preset range may be a processable range.

[0060] The preset range specifically includes a first preset range for the frame of the top and bottom frames to be welded: the frame of the top and bottom frames to be welded meets the requirements of a length of 6 to 12 m and a width of 2.4 to 4.2 m.

[0061] The second preset range for the main beam, secondary beam and reinforcement: the main beam width is 100-210mm, the main beam height is 100-350mm, the secondary beam width is 50-150mm, the secondary beam height is 50-200mm, the minimum spacing between secondary beams is greater than or equal to 200m, the minimum spacing between the main beam and the reinforcement is greater than or equal to 200mm, the minimum spacing between the reinforcement is greater than or equal to 300mm, the number of main beams is equal to 2, the number of secondary beams is less than or equal to 40, and the main beam, secondary beam and reinforcement are all rectangular tubes.

[0062] The third preset range ("standard workpiece" specification definition): the length of the secondary beams is consistent, the joint form at the same end is consistent, there are less than 3 stiffeners between the secondary beams, the stiffener width is 50-150mm, the stiffener height is 50-200mm, the main beam, secondary beam, and stiffener cross-section must be consistent, and the main beam, secondary beam, and stiffener height must be consistent.

[0063] In an optional embodiment, a process library is pre-stored in the process determination module 122, and the process library includes size information, quantity information, position information, relative position information between target components and placement process stored in a corresponding relationship, and also includes welding categories, interface types, welding lengths and welding processes stored in a corresponding relationship.

[0064] In an optional embodiment, the process determination module 122 is specifically configured to determine the placement process corresponding to the target component based on the size information, quantity information, position information and relative position information between the target components, and determine the welding process corresponding to the welding position based on the welding category, interface type and welding length corresponding to the welding position.

[0065] In an optional embodiment, the placement process corresponding to the target component includes: the placement position, the placement order and the placement direction. The welding process corresponding to the welding position includes: the welding direction, the welding order, the welding current and voltage, the welding swing amplitude and the laser repositioning position data. The laser repositioning position data can be the welding position determined by re-detection based on the generated detection laser, that is, the position data of the weld.

[0066] In this embodiment, the welding robot performs welding at the welding position to form a weld. The process library is a database of placement processes and welding processes, and different placement processes and welding processes can be determined according to different situations. Different welding positions may correspond to different welding processes. The welding processes corresponding to flat welding and vertical welding will differ in current, voltage and welding speed. By determining the corresponding placement process and welding process through the process library, errors in manual image recognition and manual programming of the equipment are avoided, ensuring the accuracy and consistency of information transmission.

[0067] In this embodiment, as an example, the process determination module 122 can produce the placement process and welding process corresponding to the secondary beam according to the position information about the weld and the secondary beam provided by the information determination module 121.

[0068] In this embodiment, the placement process includes not only the placement position, placement order and placement direction, but also alignment information. The welding process will have corresponding process information adjustment according to different interface types and different weld types. The specific information of the welding process includes a series of data affecting welding quality, such as welding direction, welding order, welding current and voltage, welding swing and laser repositioning position data. The process determination module 122 can also be configured to generate a corresponding program according to the placement process corresponding to the target component and the welding process corresponding to the welding position, and send the corresponding program generated according to the placement process corresponding to the target component and the welding process corresponding to the welding position to the execution module 13.

[0069] In an optional embodiment, the execution module 13 is specifically configured to determine a placement path according to the placement order, execute a placement process corresponding to the target component according to the placement path, determine a welding path according to the welding order, execute a welding process corresponding to the welding position according to the welding path, and adjust the welding position according to the position data of laser repositioning before executing the welding process corresponding to the welding position according to the welding path.

[0070] In this embodiment, the execution module 13 includes a robot and other equipment. As an example, it can be a welding robot, and the other equipment can be a placement device, a production device, a sensor device, etc. The welding path includes the end point of the current welding position and the starting point of the next welding position. The next welding position is a welding position adjacent to the current welding position in the welding sequence.

[0071] In this embodiment, the execution module 13 can be configured to be connected to the information determination module 121 and the process determination module 122, and generate a complete set of welding processes and assembly processes based on the target information of the information determination module 121 and the placement process and welding process of the process determination module 122 combined with the spatial position information, as well as the robot's six-axis motion algorithm. For example, the robot needs to know the relative position of the two welds between two welds. The execution module 13 will calculate the end point of the previous weld and the starting point of the next weld, make a path transition between them, and generate a detection laser before welding. According to the position data of the laser repositioning calculated by the laser system, and the anti-collision strategy, the position between the two welds is adjusted. The series connection between welds is generated and adjusted by the execution module 13.

[0072] In an optional embodiment, the welding production system further includes: an interference detection module, the interference detection module being configured to determine the position information of the positioning block before executing the placement process corresponding to the target component according to the placement path, and determine whether the distance between the positioning block and the target component is greater than a preset distance according to the position information of the positioning block and the position information of the target component. Wherein, when the distance between the positioning block and the target component is less than or equal to the preset distance, the position of the positioning block is adjusted.

[0073] In this embodiment, the interference detection module is a new functional module customized and developed according to the on-site hardware. Interference detection is intended to detect whether there will be interference problems with the positioning blocks of the on-site tooling before the secondary beam is placed, and to predict in advance before assembly and allow the system to make accurate judgments. As an example, the user inputs the status of each positioning block in turn according to the on-site situation to determine the position information of the positioning block. The status of each positioning block will only exist in one of the three positions (upper, middle and lower), and then the interference detection module will adjust the position of the tooling according to the position information of the positioning block. Then, according to the position information and relative position information of the target component to be assembled, collision calculation will be performed to calculate the shortest distance between each positioning block and each secondary beam, and determine whether the shortest distance between the positioning block and the secondary beam is greater than the preset distance. When the shortest distance between the positioning block and the secondary beam is less than or equal to the preset distance, the interference detection module will generate prompt adjustment information, and the user can adjust the position of the positioning block that needs to be adjusted according to the prompt adjustment information, and reflect it in the digital twin platform in a three-dimensional display.

[0074] In an optional implementation, the welding production system further includes a control module. The process determination module 122 is connected to the execution module 13 through the control module.

[0075] In this embodiment, the control module is also connected to the input terminal module 11 and the welding determination module 12, and can also be connected to the digital twin platform. As an example, the control module can be a PLC control module, which is responsible for all equipment control in the welding production system, including signal control between robots, motion control of external devices, and input information of the touch interactive screen. And in the production stage, the interactive control between robots and people, as well as many controls such as safety control, are responsible for the specific control of each step of the entire welding production process.

[0076] In an optional embodiment, the welding production system further includes: a target component production module, the target component production module is configured to determine production information of the target component according to the three-dimensional model corresponding to the target component. The target component is produced according to the production information of the target component. The production information of the target component includes size information, quantity information, etc.

[0077] In this embodiment, the process personnel can create a new project based on the project information, and import the model image of the top and bottom frames to be welded in the project according to the actual production requirements, or enter the custom size and define the relevant parameters. The process personnel upload the production information of the parsed target component to the production equipment. The production personnel carry out production according to the tasks uploaded by the process personnel.

[0078] In order to improve the accuracy of the component welding process and optimize the processing efficiency of the entire process, the present invention provides a welding production system, including automatic parsing of DWG and IFC format files, extracting the corresponding geometric information of the top and bottom frames to be welded and the process information at the nodes. The welding production system will automatically generate the robot's processing program code based on the parameters obtained by the analysis, and directly drive the equipment in the production line to perform processing operations. The welding production system can be applied to the entire production process, from design, process planning to actual construction, forming a complete intelligent industrial chain. Through this system, enterprises can achieve seamless docking between design and production, avoid information islands, and ensure accurate data transmission and execution in each link, ultimately improving product quality and production efficiency.
