Description

Technical Field

[0002] Fireplace tables are not only used as dining tables in cold areas, but also have heating functions. Traditional fireplace tables are usually composed of wood, metal frames and built-in stoves. As people's requirements for the aesthetics and functionality of fireplace tables increase, special-shaped fireplace tables are gradually becoming popular in the market. Special-shaped fireplace tables used outdoors are also becoming more and more popular in the market because they can adapt to unique outdoor usage scenarios. The design of special-shaped fireplace tables is different from traditional square or round tabletops, but adopts more complex geometric shapes, such as polygons, streamlines or other irregular shapes. In the manufacturing process of special-shaped fireplace tables, how to weld special-shaped fireplace tables is a key technical issue, especially at the connection between the metal frame and the tabletop. The complex shape of the special-shaped fireplace table increases the difficulty of welding.

[0003] The frame of a special-shaped fire table usually has complex curves or irregular edges, and the shape of the special-shaped fire table makes it difficult to maintain uniform welds and good sealing during welding. Existing welding technology is difficult to meet the needs of complex shapes, resulting in unstable welding quality for special-shaped fire tables, and prone to problems such as uneven welds or incomplete welding. At the same time, since the fire table used outdoors has weight restrictions, the metal frame of the special-shaped fire table used outdoors is prone to thermal deformation due to high temperature during the welding process, especially for some thin-walled materials or high-strength alloy materials.

[0035] The following is a detailed description of an automatic welding device for an outdoor fireplace table provided in an embodiment of the present application with reference to specific examples.

[0036] Figure 1 This is a schematic diagram of the main structure of an automatic welding device for an outdoor fire table provided in an embodiment of the present application. Figure 2 for Figure 1 A schematic diagram of the partial structure of an automatic welding device for an outdoor fire table at A, Figure 3 for Figure 2 A schematic diagram of the structure of the BB section of an automatic welding device for an outdoor fire table, Figure 4 for Figure 3 A schematic diagram of the C-direction structure of an automatic welding device for an outdoor fire table, Figure 5 A schematic diagram of the structure of an automatic welding device for an outdoor fire table provided in an embodiment of the present application is shown in FIG. Figures 1 to 5 As shown, the automatic welding equipment includes a first support frame 1 and a second support frame 2.

[0037] like Figure 1As shown, in order to solve the above-mentioned problems, an embodiment of the present application proposes an automatic welding device for an outdoor fire table, including a first support frame 1 and a second support frame 2, and a plurality of first welding rails 11 are provided on the first support frame 1, and the first welding rails 11 are used to carry the first welding head 12, and the first welding head 12 is used to weld the supporting structure 31 of the fire table.

[0038] like Figure 1 As shown, a second welding rail 21 is provided on the second support frame 2. The second welding rail 21 is used to carry a second welding head 22. The second welding head 22 is used to weld the support structure 31 and the table top 32 of the fire table.

[0039] Structurally, the support structure 31 includes a plurality of side panels 311 , and the plurality of side panels 311 constitute the support structure 31 .

[0040] During the welding process, the first welding head 12 moves along the first welding rail 11 and welds the supporting structure 31 of the fire table, and the second welding head 22 moves along the second welding rail 21 and welds the supporting structure 31 and the table top 32. In this way, the uniformity and stability of the welding can be ensured, thereby improving the welding quality.

[0041] During the actual welding process, the movement of the first welding head 12 along the first welding guide rail 11 can ensure that the first welding head 12 maintains a stable motion trajectory during the welding process, avoiding the problem of uneven welds caused by the shaking of the first welding head 12. The welding guide rail of the second welding head 22 can ensure the precise positioning of the second welding head 22 when welding the support structure 31 and the table top 32, thereby improving the welding accuracy.

[0042] In the prior art, welding equipment is usually operated manually, and the welding quality and efficiency are difficult to guarantee. However, the present invention not only improves the welding efficiency but also guarantees the welding quality through the automated welding equipment. In particular, for the complex structure of the special-shaped stove table, the automated welding equipment of the present invention can effectively solve the problems in the welding process and ensure the uniformity and stability of the welding.

[0043] In the embodiment of the present application, by adopting the design of the first support frame 1 and the second support frame 2, stable support can be provided during the welding process, avoiding the problem of uneven welds caused by the shaking of the first welding head 12 and the second welding head 22. At the same time, by setting the first welding guide rail 11 and the second welding guide rail 21, the precise positioning of the welding head during the welding process can be ensured, thereby improving the accuracy and quality of welding.

[0044] In practical applications, the automatic welding equipment of the present invention can be adjusted according to different fire table designs to meet different welding requirements. For example, the length and position of the welding rail can be adjusted according to the size and shape of the fire table to ensure uniformity and stability of welding.

[0045] In some implementations, the present invention can also monitor the motion trajectory of the welding head and the welding quality in real time during the welding process, and make adjustments through a feedback control system, thereby further improving the accuracy and quality of the welding.

[0046] The beneficial effect of the above-mentioned implementation method is that the embodiment of the present application solves the problems of unstable welding quality and low welding efficiency in the prior art by adopting automated welding equipment. In particular, for the complex structure of special-shaped stove tables, the present invention can provide a high-precision and high-efficiency welding solution.

[0047] The beneficial effect of the above-mentioned implementation method is that the structural design of the first support frame and the second support frame can provide stable support during the welding process and avoid the problem of uneven welds caused by shaking of the welding head.

[0048] The beneficial effect of the above-mentioned implementation method is that the movement of the first welding head along the first welding guide rail can ensure that the first welding head maintains stable welding during the welding process, and then the welding guide rail of the second welding head can ensure the stability of the second welding head when welding the support structure and the table top, thereby ensuring the overall welding quality.

[0049] The beneficial effect of the above implementation is that the first welding guide rail and the second welding guide rail can be customized according to the shape of the special-shaped fire table, thereby improving the welding efficiency of the special-shaped fire tables of various shapes.

[0050] In some implementations, a positioning assembly 13 is further provided on the first welding head 12, and the positioning assembly 13 is used to abut against the support structure 31 to position the support structure 31. The ends of the plurality of first welding rails 11 are close to the second welding rail 21, and when the positioning assembly 13 moves to the ends of the first welding rails 11, the positioning assembly 13 positions the support structure 31 close to the second welding rail 21.

[0051] In the embodiment of the present application, a positioning assembly 13 is further provided on the first welding head 12, and the positioning assembly 13 enables the support structure 31 to be accurately positioned during the welding process. The positioning assembly 13 is used to abut against the support structure 31 to position the support structure 31, and the accuracy of the welding position can be ensured. The positioning assembly 13 can effectively prevent the support structure 31 from being displaced during the welding process by abutting against the support structure 31, thereby ensuring the welding quality.

[0052] Structurally, the ends of the multiple first welding rails 11 are close to the second welding rails 21, so that when the positioning assembly 13 moves to the end of the first welding rail 11, the positioning assembly 13 can position the support structure 31 close to the second welding rail 21, thereby improving the precise positioning of the second welding head 22 on the second welding rail 21 when welding the support structure 31 and the table top 32, and further improving the stability and accuracy of the welding process.

[0053] It should be noted that the positioning assembly can be implemented in a variety of ways, such as mechanical abutment, and positioning the support structure through devices such as springs or cylinders. Regardless of the method used, it can ensure that the positioning assembly can stably and reliably position the support structure during the welding process.

[0055] The beneficial effect of the above implementation is that the positioning assembly can position the support structure close to the second welding guide rail, further improving the stability and accuracy of the support structure and the desktop welding process.

[0056] In some implementations, the first welding head 12 includes a fixed frame 121, a driving assembly 122, a first roller 123, a second roller 124, a third roller 125 and a welding portion 126. The driving assembly 122 is disposed on the fixed frame 121, the first roller 123 and the first side wall of the first welding guide rail 11 are rotatably abutted, the second roller 124 and the second side wall of the first welding guide rail 11 are rotatably abutted, the third roller 125 and the third side wall of the first welding guide rail 11 are rotatably abutted, and a rack 111 is provided on the fourth side wall of the first welding guide rail 11 along the length of the first welding guide rail 11. The driving assembly 122 is connected to the gear and the rack 111 through a transmission connection, and the driving assembly 122 is used to drive the first welding head 12 to move along the first welding guide rail 11.

[0057] like Figures 2 to 4As shown, the first welding head 12 includes a fixed frame 121, a driving assembly 122, a first roller 123, a second roller 124, a third roller 125 and a welding portion 126, the driving assembly 122 is arranged on the fixed frame 121, the first roller 123 and the first side wall of the first welding guide rail 11 are rotatably abutted, the second roller 124 and the second side wall of the first welding guide rail 11 are rotatably abutted, the third roller 125 and the third side wall of the first welding guide rail 11 are rotatably abutted, and a rack 111 is provided on the fourth side wall of the first welding guide rail 11 along the length of the first welding guide rail 11. The driving assembly 122 is connected by a gear and the rack 111, and the driving assembly 122 is used to drive the first welding head 12 to move along the first welding guide rail 11, so that the first welding head 12 can move smoothly along the first welding guide rail 11, and through the transmission connection between the gear and the rack, the driving assembly 122 can accurately control the movement of the first welding head 12.

[0058] Structurally, the first roller 123 is rotationally abutted against the first side wall of the first welding guide rail 11, the second roller 124 is rotationally abutted against the second side wall of the first welding guide rail 11, and the third roller 125 is rotationally abutted against the third side wall of the first welding guide rail 11. The first roller 123, the second roller 124 and the third roller 125 can cooperate with each other to achieve stable positioning of the fixing frame 121 relative to the first welding guide rail 11.

[0059] Exemplarily, the first roller 123, the second roller 124 and the third roller 125 may be made of wear-resistant materials to increase their service life.

[0060] Exemplarily, the drive assembly 122 may be an electric motor, a servo motor or other suitable drive devices, and the transmission connection between the gear and the rack may achieve high-precision motion control.

[0061] In some implementations, the welding portion 126 is rotatably connected to the fixing frame 121 , a spring is provided inside the welding portion 126 for driving the welding portion 126 to reset, the welding portion 126 is used to fix the welding rod, and the welding portion 126 welds the supporting structure 31 through the welding rod.

[0062] Structurally, the first welding guide rail 11 can weld the support structure 31 by guiding the first welding head 12. At the same time, the spring in the first welding head 12 can ensure that the welding head always maintains the contact state between the welding rod and the support structure 31 during the welding process, thereby ensuring the welding quality.

[0063] Exemplarily, the spring of the welding head may be in the form of a compression spring, a torsion spring, etc., to ensure that the welding head always maintains appropriate pressure during the welding process.

[0064] Structurally, a power supply structure for supplying power to the welding rod may be provided on the welding portion 126 .

[0065] Exemplarily, the structures of the first welding head 12 and the second welding head 22 can be the same, and the matching method of the second welding head 22 and the second welding guide rail 21 can be the same as the matching method of the first welding head 12 and the first welding guide rail 11. The structure of the second welding head 22, the second welding head 22 and the second welding guide rail 21 matching each other will not be repeated here.

[0066] The beneficial effect of the above-mentioned implementation method is that by arranging a drive assembly, a roller and a gear rack transmission structure on the first welding head, the precise movement of the first welding head along the first welding guide rail is achieved, thereby ensuring the stability of the welding process and the welding quality, and being able to effectively solve problems such as uneven welds, incomplete welding and thermal deformation, thereby improving the welding accuracy and efficiency.

[0067] The beneficial effect of the above implementation is that a spring for driving the welding head to reset is provided in the welding head, which can ensure that the welding head always maintains the contact state between the welding rod and the supporting structure during the welding process, thereby ensuring an efficient welding effect.

[0068] In some implementations, the positioning assembly 13 includes a support wheel 131 for abutting against the support structure 31, the welding rod of the first welding head 125 is tilted and fixed relative to the side plate 311 of the support structure 31, and the support wheel 131 is located in front of the welding part 126 in the movement direction of the first welding head 12.

[0069] In the embodiment of the present application, the positioning assembly 13 is used to ensure that the support structure 31 remains stable during the welding process, thereby improving the welding stability of the support structure 31.

[0070] Structurally, the support wheel 131 can effectively prevent the support structure 31 from being displaced during the welding process by abutting against the support structure 31, thereby ensuring the accuracy and quality of welding. The welding portion 126 fixes the welding rod at an angle relative to the side plate of the support structure. This design can optimize the welding angle, improve the firmness and aesthetics of the welding, and can prevent the welding rod of the welding portion 126 from being stuck, thereby improving the stability of the welding process.

[0071] Structurally, the positioning assembly 13 positions the support structure 31 close to the second welding rail 21 . Specifically, the support structure 31 close to the second welding rail 21 can be positioned by the support wheel 131 to ensure the subsequent welding quality of the support structure 31 and the table top 32 .

[0072] Structurally, the support wheels are located in front of the welding head. This arrangement enables the support wheels to support the welding part before the welding head completes welding, thereby ensuring the stability of welding.

[0073] Structurally, the support wheel can be made of high temperature resistant material to adapt to the high temperature environment generated during the welding process, so as to avoid the heat generated by the welding from affecting the support wheel.

[0074] Structurally, the position of the support wheel can be fine-tuned by an adjusting device to ensure that it is always located in front of the welding head and is in close contact with the support structure to position the support structure.

[0075] Structurally, the tilted fixing method of the welding head can adjust the angle of the welding head relative to the supporting structure by adjusting the length of the welding rod.

[0076] The solution of the present application solves the problem of easy displacement of the supporting structure during welding in the prior art by providing a positioning assembly and a supporting wheel, thereby improving the accuracy and quality of welding. The tilted fixing design of the welding head to the welding rod makes the welding angle more reasonable, effectively improving the firmness and aesthetics of the welding. Therefore, the present application provides an efficient and stable welding solution, which is particularly suitable for welding supporting structures of complex shapes.

[0077] The beneficial effect of the above implementation method is that the welding part fixes the welding rod at an angle relative to the side plate of the supporting structure, which can improve the firmness and aesthetics of the welding and can prevent the welding rod of the welding part from being stuck by the supporting structure, thereby improving the stability of the welding process.

[0078] The beneficial effect of the above implementation is that the layout of the support wheel in front of the welding head can further enhance the stability of the support wheel in positioning the support structure during the welding process, thereby avoiding displacement and deformation of the support structure during the welding process.

[0079] In some implementations, the automatic welding equipment also includes a control component 14, and an angle sensor 126a for detecting the rotation angle of the welding part 126 is provided in the welding part 126. The control component 14 and the angle sensor 126a are electrically connected. The control component 14 is used to control the working state of the driving component 122 according to the rotation angle of the welding part 126.

[0080] Figure 6 A control structure diagram of an automatic welding device for an outdoor fire table provided in an embodiment of the present application is shown in FIG. Figure 6As shown, the automatic welding equipment also includes a control component 14. An angle sensor 126a for detecting the rotation angle of the welding part 126 is provided in the welding part 126. The control component 14 and the angle sensor 126a are electrically connected. The control component 14 is used to control the working state of the driving component 122 according to the rotation angle of the welding part 126. When working, the control component 14 can obtain the rotation angle information of the welding part 126 in real time. The control component adjusts the working state of the driving component according to the rotation angle information of the welding part 126 to ensure the accuracy and stability during the welding process.

[0081] For example, during control, when the angle sensor 126a detects that the rotation angle of the welding part 126 reaches a preset angle value, the control component 14 can control the driving component 122 to stop moving or adjust the position of the welding part 126 to avoid errors in the welding process.

[0082] Exemplarily, the angle sensor 126a can be an optical encoder, a Hall effect sensor or a potentiometer, etc. The angle sensor 126a can accurately detect the rotation angle of the welding part 126 and transmit the data to the control component. After receiving the angle data, the control component 14 can control the action of the driving component 122 through a preset algorithm and logic.

[0083] The beneficial effect of the above-mentioned implementation method is that by arranging an angle sensor in the welding part and electrically connecting the angle sensor to the control component, real-time monitoring and control of the rotation angle of the welding part are achieved, thereby effectively improving the accuracy and stability of the welding process, reducing welding errors, and ensuring welding quality.

[0084] In some implementations, a vibration sensor 126b for detecting the vibration state of the welding portion 126 is provided in the welding portion 126, and the control component 14 and the vibration sensor 126b are electrically connected. The control component 14 is used to control the working state of the driving component 122 according to the vibration state of the welding portion 126.

[0085] like Figure 6 As shown, a vibration sensor 126b for detecting the vibration state of the welding portion 126 is provided in the welding portion 126, and the control component 14 and the vibration sensor 126b are electrically connected. The control component 14 is used to control the working state of the driving component 122 according to the vibration state of the welding portion 126. By arranging the vibration sensor 126b in the welding head, the vibration state of the welding portion during the working process can be detected in real time. The vibration sensor transmits the detected vibration signal to the control component 14. The control component 14 can determine the working state of the welding head according to the vibration signal and control the working state of the driving component 14 accordingly.

[0086] Structurally, the vibration sensor may be a piezoelectric vibration sensor or an acceleration sensor, etc., which can detect the vibration frequency and amplitude of the welding part during the welding process to determine whether the welding head is in a normal working state.

[0087] For example, if it is detected that the vibration amplitude of the welding part exceeds a preset threshold, the control component will promptly adjust or stop the operation of the driving component to ensure the welding quality.

[0088] During operation, the signal from the vibration sensor can also be used to monitor the wear of the weld, so that the weld can be maintained and replaced in time, and the service life of the weld can be extended.

[0089] The beneficial effect of the above-mentioned implementation method is that a vibration sensor is arranged in the welding head, which can detect the vibration state of the welding head during operation in real time, and can effectively improve the stability and accuracy of the welding process according to the vibration state of the welding part during operation, thereby avoiding welding quality problems caused by excessive vibration of the welding head.

[0090] The beneficial effect of the above implementation is that the signal of the vibration sensor can be used to monitor the wear of the welding part, perform maintenance and replacement in time, and extend the service life of the equipment.

[0091] The beneficial effect of the above-mentioned implementation method is that, by adding vibration sensors and corresponding control components, the welding equipment can maintain high precision and high stability in a complex welding environment, can better adapt to the welding needs of special-shaped fire tables for outdoor use, solves the problem of unstable welding quality caused by vibration of the welding part, and improves welding efficiency and quality.

[0092] In some implementations, a distance sensor 126c for detecting the distance from the first welding head 12 to the desktop 32 is provided on the fixed frame 121, and the control component 14 is electrically connected to the distance sensor 126c. The control component 14 is used to control the working state of the second welding head 22 according to the distance from multiple first welding heads 12 to the desktop 32.

[0093] When welding a special-shaped stove table for outdoor use, the distance from the welding head to the desktop is monitored by the distance from the welding part to the desktop to determine whether it is necessary to start the second welding head 22 for automatic welding. A distance sensor 126c for detecting the distance from the first welding head 12 to the desktop 32 is provided on the fixed frame 121. The control component 14 and the distance sensor 126c are electrically connected. The control component 14 is used to control the working state of the second welding head 22 according to the distance from multiple first welding heads 12 to the desktop 32. The distance sensor 126c can detect the distance from the first welding head 12 to the desktop 32, and transmit the detected distance from the first welding head 12 to the desktop 32 to the control component 14. The control component 14 controls the working state of the second welding head 22 according to the distance from the first welding head 12 to the desktop 32.

[0094] Exemplarily, the distance sensor may be a laser distance sensor, an ultrasonic sensor, an infrared distance sensor, or the like.

[0095] The beneficial effect of the above-mentioned implementation method is that by arranging a distance sensor on the fixed frame, the distance from the first welding head to the table top is detected in real time, and the working state of the second welding head is adjusted according to the detected distance information through the control component, thereby realizing automatic control of the second welding head, and improving the welding production efficiency when welding complex-shaped special-shaped stove tables.

[0096] In some implementations, a tilt sensor 121a for detecting the tilt angle of the fixing frame 121 is provided on the fixing frame 121. The tilt sensor 121a is electrically connected to the control component 14. The control component 14 is used to control the working state of the driving component 122 according to the tilt angle of the fixing frame 121.

[0097] like Figure 6 As shown, a tilt sensor 121a for detecting the tilt angle of the fixing frame 121 is provided on the fixing frame 121, and the tilt sensor 121a is electrically connected to the control component 14. The control component 14 is used to control the working state of the driving component 122 according to the tilt angle of the fixing frame 121. The tilt sensor can detect the tilt angle of the fixing frame in real time and transmit the detection result to the control component. The control component can adjust the working state of the driving component according to the detection result of the tilt sensor to ensure stability and accuracy during the welding process.

[0098] For example, the inclination sensor may use a capacitive inclination sensor, a photoelectric inclination sensor, or a MEMS (micro-electromechanical system) inclination sensor, etc. These sensors can accurately measure the inclination angle of the fixing frame and transmit the data to the control component.

[0099] The beneficial effect of the above-mentioned implementation method is that by arranging an inclination sensor on the fixed frame and electrically connecting the inclination sensor and the control component, the working state of the driving component can be adjusted according to the inclination angle. During the welding process, the stability and accuracy of the welding head can be ensured according to the inclination angle of the fixed frame. The present application can better adapt to the welding requirements of complex-shaped special-shaped stove tables and improve the welding quality and efficiency.

[0100] In some implementations, the driving assembly 122 is located on the central axis of the fixing frame 121 , and the number of the second rollers 124 is two, and the two second rollers 124 are respectively disposed on both sides of the central axis of the fixing frame 121 .

[0101] like Figure 2 As shown, the driving assembly 122 is located on the central axis of the fixed frame 121, and the number of second rollers 124 is two. The two second rollers 124 are respectively arranged on both sides of the central axis of the fixed frame 121. By arranging the driving assembly on the central axis of the fixed frame of the automatic welding equipment, it helps to ensure that the welding head can maintain a stable motion trajectory during the welding process, and can avoid the problem of uneven welding caused by eccentricity.

[0102] Structurally, the two second rollers 124 are respectively disposed on both sides of the central axis of the fixing frame, which can effectively and evenly support the weight of the first welding head 12 and further improve the stability of the welding process.

[0103] Structurally, the structure of the second roller 124 can be optimized according to the shape of the first welding guide rail 11, so that the second roller 124 can cooperate with the first welding guide rail 11, ensuring that the second roller 124 can run smoothly on the guide rail.

[0104] The beneficial effect of the above implementation method is that by setting the driving assembly on the central axis of the fixing frame and adopting a double roller structure, the stability and accuracy of the welding process can be effectively improved, and the deviation and unevenness problems that may occur during the welding process can be reduced.

[0105] Figure 7 A schematic diagram of a flow chart of an automatic welding method for an outdoor fireplace table provided in an embodiment of the present application, such as Figure 7 As shown, an embodiment of the present application further provides an automatic welding method for an outdoor fire table, using any of the automatic welding equipment for an outdoor fire table described above, and the method includes S110 to S120, and S110 to S120 are specifically described below.

[0106] S110 , a plurality of first welding heads 12 weld a plurality of side panels 311 of the support structure 31 of the fire table along the first welding guide rails 11 .

[0107] The support structure of the fire table usually includes a plurality of side panels, which need to be welded to form a stable support frame. By using a plurality of first welding heads to weld the side panels along the first welding guide rail, multiple welding operations can be performed simultaneously, thereby improving welding efficiency. The positioning assembly of the first welding head can ensure the accurate positioning of the welding head and the side panel, thereby improving welding accuracy. Through the above method, the technical solution improves the accuracy and efficiency of the special-shaped fire table during welding.

[0108] S120 , after the first welding heads 12 have completed welding the support structure 31 of the fireplace table, the second welding heads 22 weld the support structure 31 and the table top 32 of the fireplace table.

[0109] After the welding of the support structure is completed, the second welding head 22 welds the support structure 31 and the table top 32. Since the connection between the table top 32 and the support structure 31 is usually a key area for welding, the positioning assembly 13 of the first welding head 12 positions the support structure 31 close to the second welding guide rail 21, so that the second welding head 22 can perform fine welding on these areas, thereby ensuring the firmness and aesthetics of the welding of the support structure 31 and the table top 32.

[0110] The beneficial effect of the above-mentioned implementation method is that the method of the embodiment of the present application can significantly improve the welding quality and production efficiency of special-shaped fire tables, and meet the market requirements for aesthetics and functionality.

[0111] In some implementations, the above method also includes: detecting the rotation angle of the welding part 126 through the angle sensor 126a, detecting the vibration state of the welding part 126 through the vibration sensor 126b, when the rotation angle of the welding part 126 is less than the preset rotation angle, or the vibration amplitude of the welding part 126 is greater than or equal to the preset vibration amplitude, the control component 14 controls the driving component 122 to stop moving.

[0112] When welding, since the welding part 126 fixes the welding rod at an angle relative to the side plate of the supporting structure, this design can optimize the welding angle, thereby improving the firmness and aesthetics of the welding, and can prevent the welding rod of the welding part 126 from being stuck. The angle sensor 126a can detect the rotation angle of the welding part 126. When the rotation angle of the welding part 126 is less than the preset rotation angle, it means that the length of the welding rod on the welding part 126 is too short, resulting in too small a rotation angle of the welding part 126, which may result in poor welding effect, and may cause the welding rod of the welding part 126 to be stuck.

[0113] Exemplarily, with the welding rod being vertically 0° relative to the side plate of the supporting structure as a reference, the preset rotation angle may be 20°.

[0114] During welding, the vibration sensor can detect the vibration state of the welding part 126. When the vibration amplitude is greater than or equal to the preset vibration amplitude, it means that the vibration amplitude of the welding part 126 is too large, which may cause the welding quality to deteriorate. At this time, the control component 14 can control the driving component to stop moving, thereby avoiding deviations or welding quality problems during the welding process.

[0115] The beneficial effect of the above-mentioned implementation method is that by detecting the rotation angle of the welding part through the angle sensor, and detecting the vibration of the welding part through the angle sensor, it is possible to avoid the welding rod length being too short and the vibration amplitude being too large during the welding process, thereby achieving high-precision and high-efficiency welding of special-shaped stove tables, and solving the problem that traditional welding methods are difficult to cope with complex shapes and high-temperature deformation.

[0116] In some implementations, the above method also includes: detecting the sequential tilt angle of the fixed frame 121 through the inclination sensor 121a, detecting the distance from the first welding head 12 to the desktop 32 through the distance sensor 126c, when the inclination angle change value of the inclination angle at adjacent moments in the sequential tilt angle is less than the preset inclination angle change value, and when the distances from multiple first welding heads 12 to the desktop 32 are all less than the preset distance, the control component 14 controls the second welding head 22 to start welding the support structure 31 and the desktop 32.

[0117] During welding, the sequential tilt angle of the fixing frame 121 can be detected by the tilt sensor 121a. The sequential tilt angle is the tilt angle detected at multiple moments, and the welding state can be determined by the sequential tilt angle.

[0118] Exemplarily, the sequential tilt angle may be a tilt angle of the fixing frame 121 within each interval of 1 second.

[0119] During welding, when the tilt angle change value of the tilt angle at adjacent moments in the sequential tilt angle is less than the preset tilt angle change value, it indicates that the tilt angle of the fixing frame 121 has no sudden change, that is, the welding process of the multiple first welding heads 12 during the welding of the supporting structure 31 is relatively stable.

[0120] During welding, the distance from the first welding head 12 to the desktop 32 can be detected by the distance sensor 126c. When the welding process of multiple first welding heads 12 on the support structure 31 is relatively stable, and when the distance from multiple first welding heads 12 to the desktop 32 is less than the preset distance, the control component 14 can control the second welding head 22 to start welding the support structure 31 and the desktop 32, and then the support structure 31 and the desktop 32 can be welded after the multiple first welding heads 12 have performed relatively stable welding on the support structure 31.

[0121] The beneficial effect of the above-mentioned implementation method is that by detecting and determining whether the welding process of multiple first welding heads during the support structure welding process is relatively stable, and when the distances from the multiple first welding heads to the table top are less than the preset distance, the support structure and the table top can be welded after the support structure is welded relatively stably, thereby improving the stability of the welding state of the support structure and the table top.

[0122] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
