[0055] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0056] Reference Figure 1 , Figure 1 It is a schematic diagram of the structure of the corrugated web welding equipment in the hardware operating environment involved in the embodiment of the present invention.

The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM) or a stable memory (Non-volatile Memory, NVM), such as a disk memory. The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0058] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation on the corrugated web welding device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0059] like Figure 1 As shown, the memory 1005 identified as a computer storage medium may include an operating system, a network communication module, a user interface module, and a corrugated web welding program.

[0060] exist Figure 1 In the corrugated web welding equipment shown, the network interface 1004 is mainly used to connect to the background server and communicate data with the background server; the user interface 1003 is mainly used to connect to the user device; the corrugated web welding equipment calls the corrugated web welding program stored in the memory 1005 through the processor 1001, and executes the corrugated web welding method provided by the embodiment of the present invention.

[0061] Based on the above hardware structure, an embodiment of the corrugated web welding method of the present invention is proposed.

[0062] Reference Figure 2 , Figure 2 The figure is a flow chart of the first embodiment of the corrugated web welding method of the present invention, and provides the first embodiment of the corrugated web welding method of the present invention.

[0063] In this embodiment, the corrugated web welding method comprises the following steps:

[0064] Step S10: Obtaining the total material thickness and profile information of the corrugated web to be welded.

[0065] It should be noted that the execution subject of this embodiment may be a device including a corrugated web welding system, and the device may be a computing device, such as a tablet computer, a personal computer, etc. The device may be connected to an infrared sensor, a welding camera, a flux box, a wire feed wheel, a wire reel, a control box, etc., wherein the welding camera is used to collect welding images, and locate the weld position in the welding image in combination with the signal collected by the infrared sensor, so as to accurately determine the weld coordinates. This embodiment takes the corrugated web welding device as the execution subject to explain the embodiment.

[0066] It is understandable that the total material thickness can be the total thickness of the corrugated web to be welded, which can be determined according to the thickness and number of layers of the corrugated web to be welded. The total material thickness can be used to determine the time required for welding and the amount of material required for welding.

[0067] It should be understood that the contour information may refer to the corrugated web image captured by the welding camera, and the information generated by identifying the steel plate contour and contour size of the corrugated web image. The contour information includes the length, width and corrugation arc diameter of the corrugated web to be welded.

[0068] Step S20: searching for a corresponding target weld diameter in a preset weld diameter mapping table according to the total material thickness.

[0069] It should be noted that the preset welding spot diameter mapping table can be a pre-set table including the correspondence between the total material thickness and the welding spot diameter. When the plate thickness is different, the corresponding welding spot diameter is determined according to the plate thickness, so as to meet the welding of plates of various thicknesses and avoid cold welding caused by insufficient welding spot diameter.

[0070] Further, the step S20 includes: determining a target welding current range according to the total material thickness and a preset welding current mapping table; determining a minimum weld core diameter according to the target welding current range; and searching a corresponding target weld core diameter in a preset weld core diameter mapping table according to the minimum weld core diameter.

[0071] It should be noted that as the welding current increases, the depth of penetration and the weld excess height will also increase, so the welding current needs to be controlled. The preset welding current mapping table can be a pre-set correspondence between the steel plate thickness and the current required for welding. In order to improve the welding efficiency, the current required for the current welding is determined by matching the current of the thickness of the corrugated web to be welded through the preset welding current mapping table, thereby ensuring effective welding.

[0072] It is understandable that the heat generated by the arc corresponding to different currents is also different. Since the diameter of the weld core is related to the plate thickness, in order to ensure that the diameter of the subsequent weld meets the process standards and avoid pores or cracks caused by rough welds, it is necessary to determine the minimum diameter of the weld core based on the welding current, and then find the corresponding target weld spot diameter in the preset weld spot diameter mapping table based on the minimum diameter of the weld core.

[0073] It should be understood that the preset weld spot diameter mapping table is a pre-set table including the correspondence between the weld core diameter, current and weld spot diameter, wherein the weld spot diameter includes the weld core area and the heat coverage area corresponding to the current heat, and the heat coverage area refers to the area where the heat generated by the current will affect the steel plate. Therefore, the target weld spot diameter is determined based on the minimum weld core diameter and the heat coverage diameter corresponding to the current heat, which can ensure the welding quality.

[0074] Step S30: Obtain the welding joint type.

[0075] It should be noted that since plates of different shapes and thicknesses require different welding joints to complete welding, different welding methods are selected for steel plates of different materials. The type of welding joint can be determined according to different welding methods. The welding methods include fusion welding, pressure welding and brazing. Therefore, the type of welding joint can be divided into fusion welding joints, pressure welding joints and brazing joints. The fusion welding joints include but are not limited to butt joints, corner joints and end joints. The pressure welding joints can adopt lap joints or butt joints.

[0076] Step S40: determining a welding angle based on a corrugated web welding algorithm and the welding joint type, the target weld spot diameter and the contour information.

[0077] It should be noted that the corrugated web welding algorithm can be a pre-set algorithm for determining the welding angle corresponding to the welding gun, and the algorithm can be constructed by a morphological recognition algorithm and a deep learning algorithm, wherein the algorithm includes a CNN image recognition algorithm and a binarization morphological recognition algorithm.

[0078] Step S50: welding the corrugated web to be welded after adjusting the orientation of the welding gun according to the welding angle.

[0079] It should be noted that adjusting the orientation of the welding gun by the welding angle can effectively avoid welds that do not meet the standards due to problems with the welding angle.

[0080] This embodiment obtains the total material thickness and contour information of the corrugated web to be welded; searches for the corresponding target weld spot diameter in a preset weld spot diameter mapping table according to the total material thickness; obtains the welding joint type; determines the welding angle based on the corrugated web welding algorithm and the welding joint type, the target weld spot diameter and the contour information; and welds the corrugated web to be welded after adjusting the orientation of the welding gun according to the welding angle. Compared with the prior art in which manual welding of corrugated webs is difficult and labor-intensive, which affects production efficiency, this embodiment realizes automated welding and improves welding quality at the same time, thereby improving production efficiency and shortening production cycle.

[0081] Reference Figure 3 , Figure 3 This is a schematic diagram of the process of the second embodiment of the corrugated web welding method of the present invention. Figure 2 The first embodiment shown provides a second embodiment of the corrugated web welding method of the present invention.

[0082] In this embodiment, the step S40 includes:

[0083] Step S401: determining welding groove information and weld information according to the welding joint type and the contour information.

[0084] It should be noted that the welding groove refers to the pre-processed form of the joint part or end face of the corrugated web to be welded, wherein the welding groove information includes the groove shape and groove size. According to the shape of the groove, the groove is divided into various groove forms such as I-shaped (no groove), V-shaped, Y-shaped, double Y-shaped, U-shaped, double U-shaped, etc. The weld information includes information such as weld length, width, excess height and weld angle.

[0085] It is understandable that in order to ensure the welding effect, it is necessary to determine the shape and size of the welding groove and the weld length, width, excess height and weld angle according to the type of welding joint and the contour information of the steel plate to be welded, so as to ensure the welding effect.

[0086] Step S402: predicting the weld point position based on the corrugated web welding algorithm, the welding groove information and the weld seam information to obtain the predicted weld point position.

[0087] It should be noted that before welding the corrugated web, the position of the weld point needs to be predicted, so the position of the weld point needs to be predicted through the corrugated web welding algorithm, the welding groove information and the weld information.

[0088] Step S403: determining a welding angle according to the weld information, the predicted weld point position and the target weld point diameter.

[0089] It should be noted that the welding angle determines the final effect of the weld. In order to avoid rework in the later stage, the welding angle needs to be determined based on the weld information, predicted weld point location and target weld point diameter.

[0090] Furthermore, the step S403 also includes: determining the welding wire inclination angle according to the weld thickness and the weld width in the weld information; and determining the welding angle according to the welding wire inclination angle, the predicted weld point position and the target weld point diameter.

[0091] It should be noted that the wire inclination refers to the angle between the filler material and the object being welded during welding. The wire inclination is divided into two directions: wire forward inclination and wire backward inclination. The specific angle can be adjusted according to actual conditions. The direction and size of the inclination are different, and the force and heat effect of the arc on the molten pool are also different, which will affect the formation of the weld.

[0092] It is understandable that the welding angle determines the welding gun angle. Different welds require different welding gun angles. For example, when welding flat welds, the welding wire angle needs to be slightly adjusted according to the plate angle, and the welding gun angle needs to be determined according to the weld angle. When the weld is a flat weld, the welding gun angle needs to be vertical 90 degrees.

[0093] In this embodiment, the step S50 includes: acquiring weld penetration information in real time; adjusting the welding wire inclination according to the weld penetration information, the weld thickness and the weld width; and welding the corrugated web to be welded after adjusting the orientation of the welding gun according to the adjusted welding wire inclination, the predicted weld point position and the target weld point diameter.

[0094] It should be noted that the weld penetration information refers to the distance from the weld surface to the deepest part of the melting zone in the butt weld. Since the weld thickness, weld width and weld excess height are affected by the welding current, in order to avoid excessive melting of the welding wire due to the influence of the current and resulting in an uneven weld, it is necessary to adjust the welding wire inclination according to the weld penetration information, the weld thickness and the weld width.

[0095] In a specific implementation, the corrugated web to be welded is welded after the orientation of the welding gun is adjusted according to the adjusted welding wire inclination angle, the predicted welding spot position and the target welding spot diameter.

[0096] The present embodiment obtains the total material thickness and contour information of the corrugated web to be welded; searches for the corresponding target weld spot diameter in a preset weld spot diameter mapping table according to the total material thickness; obtains the welding joint type; determines the welding groove information and the weld seam information according to the welding joint type and the contour information; predicts the weld spot position based on the corrugated web welding algorithm, the welding groove information and the weld seam information to obtain the predicted weld spot position; determines the welding angle according to the weld seam information, the predicted weld spot position and the target weld spot diameter; and welds the corrugated web to be welded after adjusting the orientation of the welding gun according to the welding angle. Compared with the prior art in which manual welding of corrugated webs is difficult and labor-intensive, which affects production efficiency, the present embodiment realizes automated welding and improves welding quality at the same time, thereby improving production efficiency and shortening production cycle.

[0097] Reference Figure 4 , Figure 4 The third embodiment of the corrugated web welding method of the present invention is a schematic flow chart. Figure 3 The second embodiment shown provides a third embodiment of the corrugated web welding method of the present invention.

[0098] In this embodiment, after step S50, the following steps are further included:

[0099] Step S60: Acquire the image of the corrugated web after welding.

[0100] It should be noted that the image of the corrugated web after welding is collected by a camera, and the image can be used to determine whether the weld meets the preset indicators.

[0101] Step S70: performing weld identification on the corrugated web image based on a deep learning algorithm to obtain weld parameter information.

[0102] It should be noted that weld parameter information refers to the parameter information corresponding to the weld generated after welding, and the parameter information includes information such as weld length, width, angle, etc. Weld recognition of corrugated web images based on deep learning algorithms can be to reduce the noise of corrugated web images, remove interference factors, extract and retain information useful for later image processing, and image noise reduction can reduce the noise of video frame images through algorithms such as image graying, binarization, and filtering. The filtering algorithms include mean filtering, median filtering, etc. In practical applications, the pixel gray values ​​of the image are first classified, and the background and target are separated by the global threshold method. After obtaining the separated results, the separated image is subjected to weld target extraction by the background difference method, and the contour information of the target is extracted based on edge detection, and the weld parameter information is determined based on the contour information. By segmenting the extracted image, the interference of other welding residues is reduced, and the weld features are extracted to the maximum extent.

[0103] Step S80: Determine whether there is a weld defect based on the weld parameter information and preset weld indicators.

[0104] It should be noted that by comparing the weld angle, weld length and weld width in the weld parameter information with the preset weld indicators, a comprehensive judgment can be made as to whether there are weld defects, so as to facilitate timely repairs at a later stage.

[0105] It is understandable that the preset weld index is pre-set for judging whether the weld after welding meets the standard, and the index includes weld parameter index, and the weld parameter index includes the welding size, weld leg height, and weld straightness parameter corresponding to the weld.

[0106] Further, the step S80 includes: determining the external forming quality according to the welding size, weld leg height, and weld straightness in the weld parameter information; determining the internal welding quality according to the cracks and pores in the weld parameter information; and judging whether there is a weld defect according to the external forming quality and the internal welding quality and preset weld indicators.

[0107] It should be noted that in order to determine whether a weld has defects, the defect type is determined, that is, the root cause of the defect problem is determined by determining the defect type, so as to determine whether it can be remedied.

[0108] Step S90: When there are weld defects, the weld is repaired until the preset weld index is met.

[0109] Furthermore, the step S90 also includes: determining a weld defect processing strategy according to the defect type corresponding to the weld defect; grinding or repairing the weld according to the weld defect processing strategy; acquiring a target weld image within a preset processing area in real time; adjusting weld repair parameters according to the target weld image until the weld in the acquired target weld image meets the preset weld index.

[0110] In a specific implementation, the external forming quality is determined according to the welding size, weld leg height, and weld straightness in the weld parameter information; the internal welding quality is determined according to the cracks and pores in the weld parameter information, and the external forming quality and / or the internal welding quality are compared with the parameters corresponding to the defect indicators in the preset welding indicators to determine whether the current weld has defects. When defects exist, a corresponding defect processing strategy is determined according to the defect type, and the weld is repaired or re-welded. If the defect cannot be remedied, re-welding is required, and a target weld image in a preset processing area is obtained in real time; the weld repair parameters are adjusted according to the target weld image until the weld in the acquired target weld image meets the preset weld indicator.

[0111] This embodiment obtains the total material thickness and contour information of the corrugated web to be welded; searches for the corresponding target weld spot diameter in a preset weld spot diameter mapping table according to the total material thickness; obtains the type of welding joint; determines the welding groove information and the weld seam information according to the welding joint type and the contour information; predicts the weld spot position based on the corrugated web welding algorithm, the welding groove information and the weld seam information to obtain the predicted weld spot position; determines the welding angle according to the weld seam information, the predicted weld spot position and the target weld spot diameter; welds the corrugated web to be welded after adjusting the orientation of the welding gun according to the welding angle to obtain the image of the corrugated web after welding; performs weld recognition on the corrugated web image based on a deep learning algorithm to obtain weld parameter information; determines whether there is a weld defect according to the weld parameter information and the preset weld index; when a weld defect exists, repairs the weld until the preset weld index is met. Compared with the prior art in which manual welding of corrugated webs is difficult and labor-intensive, thus affecting production efficiency, this embodiment realizes automated welding while improving welding quality, thereby improving production efficiency and shortening the production cycle.

[0112] In addition, to achieve the above-mentioned purpose, the present invention also proposes a storage medium, on which a corrugated web welding program is stored, and when the corrugated web welding program is executed by a processor, the steps of the corrugated web welding method described above are implemented.
