Description

Technical Field

[0001] This application relates to the field of welding equipment technology, and more specifically, to an automatic welding device and method for outdoor stove tables. Background Technology

[0002] In cold regions, fireplace tables serve not only as dining tables but also as heating devices. Traditional fireplace tables typically consist of wood, a metal frame, and an embedded fireplace. As people's demands for the aesthetics and functionality of fireplace tables have increased, irregularly shaped fireplace tables have gradually gained popularity in the market. Irregularly shaped fireplace tables for outdoor use are also becoming increasingly popular due to their adaptability to unique outdoor environments. The design of irregularly shaped fireplace tables differs from traditional square or round tabletops, employing more complex geometric shapes such as polygons, streamlined forms, or other irregular shapes. In the manufacturing process of irregularly shaped fireplace tables, welding is a key technical challenge, especially at the connection between the metal frame and the tabletop, where the complex shape of the tabletop increases the difficulty of welding.

[0003] The frames of irregularly shaped fireplace tables often feature complex curves or irregular edges, making it difficult to maintain uniform welds and good sealing during welding. Existing welding techniques struggle to meet the demands of complex shapes, resulting in inconsistent welding quality and issues such as uneven or incomplete welds. Furthermore, due to weight limitations for outdoor fireplace tables, the metal frames of irregularly shaped outdoor fireplace tables are prone to thermal deformation during welding, especially with thin-walled or high-strength alloy materials. This thermal deformation distorts the frame's shape, affecting the overall structure and aesthetics of the outdoor fireplace table. Current welding equipment and processes have limitations in controlling thermal deformation, making it difficult to completely avoid material deformation. Therefore, existing welding equipment is insufficient for high-precision and efficient welding of irregularly shaped outdoor fireplace tables. Summary of the Invention

[0004] The purpose of this application is to provide an automatic welding device and method for outdoor stove tables, which solves the technical problem that existing welding equipment is unable to perform high-precision and high-efficiency welding on irregularly shaped outdoor stove tables, and achieves the technical effect of high-precision and high-efficiency welding on irregularly shaped outdoor stove tables.

[0012] In another possible implementation, the fixture is equipped with an inclination sensor for detecting the tilt angle of the fixture. The inclination sensor is electrically connected to a control component, which controls the operating state of the drive component based on the tilt angle of the fixture.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0032] Existing welding equipment and processes still have certain limitations in controlling thermal deformation. The shape of the irregularly shaped furnace table makes it difficult to maintain a uniform weld and good sealing during welding, and it is difficult to completely avoid material deformation.

[0033] Based on the above reasons, this application provides an automatic welding device for an outdoor stove table, including a first support frame and a second support frame. The first support frame has multiple first welding guide rails that support first welding heads for welding the support structure of the stove table. The second support frame has second welding guide rails that support second welding heads for welding the support structure and tabletop of the stove table. The support structure includes multiple side plates. The automatic welding device for an outdoor stove table in this application can efficiently weld irregularly shaped stove tables, ensuring weld quality and good sealing, and avoiding material deformation problems.

[0034] In some scenarios, the automatic welding equipment for outdoor stove tables according to the embodiments of this application can be applied to the welding of irregularly shaped stove tables used outdoors, which can solve the problems of unstable welding quality and low welding efficiency. In particular, for the complex structure of irregularly shaped stove tables, the present invention can provide a high-precision and high-efficiency welding solution.

[0035] The following describes in detail an automatic welding device for an outdoor stove table provided in this application embodiment, using specific examples.

[0036] Figure 1 This is a front view schematic diagram of an automatic welding device for an outdoor stove table provided in an embodiment of this application. Figure 2 for Figure 1 A partial structural diagram at point A of an automatic welding device for outdoor stove tables. Figure 3 for Figure 2 A schematic diagram of the BB section of an automatic welding device for outdoor stove tables. Figure 4 for Figure 3 A schematic diagram of the C-axis structure of an automatic welding device for outdoor stove tables. Figure 5 A bottom view of an automatic welding device for an outdoor stove table, provided as an embodiment of this application, is shown below. Figures 1 to 5 As shown, this automatic welding equipment includes a first support frame 1 and a second support frame 2. The first support frame 1 is provided with multiple first welding guide rails 11, which are used to support first welding heads 12. The first welding heads 12 are used to weld the support structure 31 of the stove table 3. The second support frame 2 is provided with second welding guide rails 21, which are used to support second welding heads 22. The second welding heads 22 are used to weld the support structure 31 and the tabletop 32 of the stove table. The support structure 31 includes multiple side plates 311.

[0037] like Figure 1As shown, in order to solve the above problems, this application embodiment proposes an automatic welding device for an outdoor stove table, including a first support frame 1 and a second support frame 2. The first support frame 1 is provided with a plurality of first welding guide rails 11, which are used to carry first welding heads 12. The first welding heads 12 are used to weld the support structure 31 of the stove table.

[0038] like Figure 1 As shown, the second support frame 2 is provided with a second welding guide rail 21, which is used to support the second welding head 22. The second welding head 22 is used to weld the support structure 31 and the tabletop 32 of the stove table.

[0039] Structurally, the support structure 31 includes multiple side plates 311, which together form the support structure 31.

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

[0041] In 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 movement trajectory during the welding process, avoiding the problem of uneven weld 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 32, thereby improving the welding accuracy.

[0042] In existing technologies, welding equipment is typically operated manually, making it difficult to guarantee welding quality and efficiency. This invention, however, utilizes automated welding equipment, which not only improves welding efficiency but also ensures welding quality. Particularly for the complex structure of irregularly shaped furnace tables, this automated welding equipment effectively solves the challenges in the welding process, ensuring the uniformity and stability of the weld.

[0043] In this embodiment, the use of a first support frame 1 and a second support frame 2 provides stable support during welding, preventing uneven welds caused by the shaking of the first welding head 12 and the second welding head 22. Simultaneously, the first welding guide rail 11 and the second welding guide rail 21 ensure precise positioning of the welding head during welding, thereby improving welding accuracy and quality.

[0044] In practical applications, the automatic welding equipment of this invention can be adjusted according to different furnace table designs to adapt to different welding needs. For example, the length and position of the welding guide rail can be adjusted according to the size and shape of the furnace table, thereby ensuring the uniformity and stability of the welding.

[0045] In some implementations, the present invention can also monitor the movement 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 precision and quality of welding.

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

[0047] The beneficial effect of the above 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 weld caused by the shaking of the welding head.

[0048] The beneficial effect of the above 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 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 tabletop, thus ensuring the overall welding quality.

[0049] The beneficial effect of the above implementation method is that the first and second welding guide rails can be customized according to the shape of the irregularly shaped stove table, which improves the welding efficiency of irregularly shaped stove tables of various shapes.

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

[0051] In this embodiment, the first welding head 12 is further provided with a positioning component 13. The positioning component 13 enables accurate positioning of the support structure 31 during the welding process. The positioning component 13 is used to abut against the support structure 31 to position the support structure 31, thereby ensuring the accuracy of the welding position. By abutting against the support structure 31, the positioning component 13 can effectively prevent the support structure 31 from shifting during the welding process, thus ensuring the welding quality.

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

[0053] It should be noted that the positioning component can be implemented in various ways, such as using mechanical contact, or employing devices such as springs or cylinders to position the support structure. Regardless of the method used, it is ensured that the positioning component can stably and reliably position the support structure during the welding process.

[0054] The beneficial effects of the above implementation method are that by setting up positioning components, the problem of inaccurate positioning of the support structure during the welding process can be effectively solved, the welding quality and efficiency can be improved, and the accuracy of the welding position can be guaranteed, thereby improving the welding quality and reducing welding defects.

[0055] The beneficial effect of the above implementation method is that the positioning component can position the support structure close to the second welding guide rail, which further improves 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 drive assembly 122, a first roller 123, a second roller 124, a third roller 125, and a welding part 126. The drive assembly 122 is mounted on the fixed frame 121. The first roller 123 rotatably abuts against the first side wall of the first welding guide rail 11, the second roller 124 rotatably abuts against the second side wall of the first welding guide rail 11, and the third roller 125 rotatably abuts against the third side wall of the first welding guide rail 11. 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 drive assembly 122 is connected to the rack 111 via gears and transmission. The drive 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 drive assembly 122, a first roller 123, a second roller 124, a third roller 125, and a welding part 126. The drive assembly 122 is mounted on the fixed frame 121. The first roller 123 rotates and abuts against the first side wall of the first welding guide rail 11, the second roller 124 rotates and abuts against the second side wall of the first welding guide rail 11, and the third roller 125 rotates and abuts against the third side wall of the first welding guide rail 11. 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 drive assembly 122 is connected to the rack 111 via gears. The drive 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. Through the transmission connection of gears and racks, the drive assembly 122 can precisely control the movement of the first welding head 12.

[0058] Structurally, the first roller 123 rotates and abuts against the first side wall of the first welding guide rail 11, the second roller 124 rotates and abuts against the second side wall of the first welding guide rail 11, and the third roller 125 rotates and abuts 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 fixed frame 121 relative to the first welding guide rail 11.

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

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

[0061] In some implementations, the welding part 126 is rotatably connected to the fixed frame 121, and the welding part 126 is provided with a spring for driving the welding part 126 to reset. The welding part 126 is used to fix the welding rod, and the welding part 126 welds the support structure 31 through the welding rod.

[0062] Structurally, the first welding guide rail 11 can guide the first welding head 12 to weld the support structure 31. At the same time, the spring inside 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, thus ensuring the welding quality.

[0063] For example, the spring of the welding head can be in the form of a compression spring, a torsion spring, etc., to ensure that the welding head maintains appropriate pressure at all times during the welding process.

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

[0065] For example, 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 mutual matching of the second welding head 22 and the second welding guide rail 21 will not be described in detail here.

[0066] The beneficial effects of the above implementation method are that by setting a drive component, roller and gear rack transmission structure on the first welding head, the precise movement of the first welding head along the first welding guide rail is realized, which ensures the stability of the welding process and the welding quality, effectively solves problems such as uneven weld, incomplete welding and thermal deformation, and improves the accuracy and efficiency of welding.

[0067] The beneficial effect of the above implementation method is that the welding head is equipped with a spring for driving the welding head to reset, which can ensure that the welding head always maintains the contact state between the welding rod and the support structure during the welding process, thus ensuring a high-efficiency welding effect.

[0068] In some implementations, the positioning component 13 includes a support wheel 131 for abutting against the support structure 31, the welding rod of the first welding head 125 is fixed at an inclination 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 direction of movement of the first welding head 12.

[0069] In this embodiment, the positioning component 13 ensures 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, by abutting against the support structure 31, can effectively prevent the support structure 31 from shifting during the welding process, thereby ensuring the accuracy and quality of the welding. The welding part 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 strength and aesthetics of the weld, and prevent the welding rod of the welding part 126 from getting stuck, thus improving the stability of the welding process.

[0071] Structurally, the positioning component 13 positions the support structure 31 near the second welding guide rail 21. Specifically, the support wheel 131 can be used to position the support structure 31 near the second welding guide rail 21 to ensure the welding quality of the support structure 31 and the tabletop 32 in the future.

[0072] Structurally, the support wheel is located in front of the welding head. This arrangement allows the support wheel to support the welding area before the welding head completes the welding process, ensuring the stability of the welding.

[0073] Structurally, the support wheel can be made of high-temperature resistant materials to adapt to the high-temperature environment generated during the welding process, thus avoiding the heat generated during welding from affecting the support wheel.

[0074] Structurally, the position of the support wheel can be finely adjusted by the adjustment device to ensure that it is always in front of the welding head and in close contact with the support structure for positioning.

[0075] Structurally, the tilting and fixing method of the welding head can be adjusted by adjusting the length of the welding rod to change the angle of the welding head relative to the supporting structure.

[0076] This application's solution, by incorporating positioning components and support wheels, solves the problem of easy displacement of the support structure during welding in existing technologies, thereby improving welding accuracy and quality. The inclined fixing design of the welding head to the welding electrode makes the welding angle more reasonable, effectively improving the weld's strength and aesthetics. Therefore, this application provides an efficient and stable welding solution, particularly suitable for welding support structures with complex shapes.

[0077] The beneficial effect of the above implementation method is that by fixing the welding rod at an angle relative to the side plate of the supporting structure, the welding part can improve the strength and aesthetics of the weld, and can also 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 method 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, and avoid 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. 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 drive component 122 according to the rotation angle of the welding part 126.

[0080] Figure 6 A schematic diagram of the control structure of an automatic welding device for an outdoor stove table is provided as an embodiment of this application, as shown below. Figure 6As shown, this 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 inside 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 drive component 122 according to the rotation angle of the welding part 126. During operation, the control component 14 can acquire the rotation angle information of the welding part 126 in real time. The control component adjusts the working state of the drive component according to the rotation angle information of the welding part 126 to ensure the accuracy and stability of the welding process.

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

[0082] For example, 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 drive component 122 through a preset algorithm and logic.

[0083] The beneficial effect of the above implementation method is that by setting 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 can be realized, 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 part 126 is provided inside the welding part 126. The control component 14 is electrically connected to the vibration sensor 126b, and the control component 14 is used to control the working state of the drive component 122 according to the vibration state of the welding part 126.

[0085] like Figure 6 As shown, a vibration sensor 126b for detecting the vibration state of the welding part 126 is provided inside the welding part 126. The control component 14 is electrically connected to the vibration sensor 126b. The control component 14 is used to control the working state of the drive component 122 according to the vibration state of the welding part 126. By setting the vibration sensor 126b inside the welding head, the vibration state of the welding part 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 drive component 14 accordingly.

[0086] In terms of structure, the vibration sensor can be a piezoelectric vibration sensor or an accelerometer, etc., which can determine whether the weld joint is in normal working condition by detecting the vibration frequency and amplitude of the welded part during the welding process.

[0087] For example, if the vibration amplitude of the welded part is detected to exceed a preset threshold, the control component will adjust or stop the operation of the drive component in a timely manner to ensure the welding quality.

[0088] During operation, the vibration sensor signal can also be used to monitor the wear of the welded parts, thereby enabling timely maintenance and replacement of the welded parts and extending their service life.

[0089] The beneficial effect of the above implementation method is that by setting a vibration sensor inside the welding head, the vibration state of the welding head during the working process can be detected in real time. Based on the vibration state of the welding part during the working process, the stability and accuracy of the welding process can be effectively improved, and welding quality problems caused by excessive vibration of the welding head can be avoided.

[0090] The beneficial effect of the above implementation method is that the signal from the vibration sensor can be used to monitor the wear of the welded parts, enabling timely maintenance and replacement, and extending the service life of the equipment.

[0091] The beneficial effects of the above implementation method are that by adding vibration sensors and corresponding control components, the welding equipment can maintain high precision and high stability in complex welding environments, better adapt to the welding needs of irregularly shaped furnace tables used outdoors, solve the problem of unstable welding quality caused by vibration of the welding part, and improve welding efficiency and quality.

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

[0093] When welding an outdoor irregularly shaped stove table, the distance from the welding head to the tabletop is monitored to determine whether the second welding head 22 needs to be started for automatic welding. The mounting frame 121 is equipped with a distance sensor 126c for detecting the distance from the first welding head 12 to the tabletop 32. 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 based on the distances from the first welding heads 12 to the tabletop 32. The distance sensor 126c can detect the distance from the first welding head 12 to the tabletop 32 and transmit the detected distance to the control component 14. The control component 14 controls the working state of the second welding head 22 based on the distance from the first welding head 12 to the tabletop 32.

[0094] For example, the distance sensor can be a laser rangefinder, an ultrasonic sensor, or an infrared rangefinder, etc.

[0095] The beneficial effect of the above implementation method is that by setting a distance sensor on the fixed frame, the distance between the first welding head and the table can be detected in real time, and the working state of the second welding head can be adjusted by the control component according to the detected distance information. This can realize the automatic control of the second welding head and improve welding production efficiency when welding complex-shaped furnace tables.

[0096] In some implementations, the mounting bracket 121 is provided with an inclination sensor 121a for detecting the tilt angle of the mounting bracket 121. The inclination sensor 121a is electrically connected to the control component 14, and the control component 14 is used to control the working state of the drive component 122 according to the tilt angle of the mounting bracket 121.

[0097] like Figure 6 As shown, the mounting bracket 121 is equipped with an inclination sensor 121a for detecting the tilt angle of the mounting bracket 121. The inclination sensor 121a is electrically connected to the control component 14. The control component 14 is used to control the working state of the drive component 122 according to the tilt angle of the mounting bracket 121. The inclination sensor can detect the tilt angle of the mounting bracket in real time and transmit the detection result to the control component. The control component can adjust the working state of the drive component according to the detection result of the inclination sensor to ensure the stability and accuracy of the welding process.

[0098] For example, the tilt sensor can be a capacitive tilt sensor, a photoelectric tilt sensor, or a MEMS (microelectromechanical system) tilt sensor, which can accurately measure the tilt angle of the fixture and transmit the data to the control components.

[0099] The beneficial effect of the above implementation method is that by setting an inclination sensor on the fixed frame and electrically connecting the inclination sensor and the control component, the working state of the drive 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. This application can better adapt to the welding needs of complex-shaped irregular furnace tables and improve welding quality and efficiency.

[0100] In some implementations, the drive assembly 122 is located on the central axis of the fixed frame 121, and there are two second rollers 124, which are respectively located on both sides of the central axis of the fixed frame 121.

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

[0102] Structurally, two second rollers 124 are respectively located on both sides of the central axis of the fixed frame, which can effectively and evenly support the weight of the first welding head 12 of the body, 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 and ensure 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 drive component on the central axis of the fixed frame and adopting a double roller structure, the stability and accuracy of the welding process can be effectively improved, and the deviation and unevenness that may occur during the welding process can be reduced.

[0105] Figure 7 A flowchart illustrating an automatic welding method for an outdoor stove table, as provided in this application embodiment, is shown below. Figure 7 As shown in the embodiment of this application, an automatic welding method for an outdoor stove table is also provided. The automatic welding equipment for an outdoor stove table described in any of the above claims is used. This method includes steps S110 to S120, which will be described in detail below.

[0106] S110, multiple first welding heads 12 are welded to multiple side plates 311 of the support structure 31 of the stove table along the first welding guide rail 11.

[0107] The support structure of a stove table typically includes multiple side panels, which need to be welded together to form a stable support frame. By using multiple first welding heads to weld the side panels along a first welding guide rail, multiple welding operations can be performed simultaneously, improving welding efficiency. The positioning components of the first welding heads ensure accurate positioning of the welding heads and side panels, thereby improving welding precision. Through the above method, this technical solution improves the precision and efficiency of welding irregularly shaped stove tables.

[0108] S120. After the first welding head 12 has been welded to the support structure 31 of the stove table, the second welding head 22 welds the support structure 31 and the tabletop 32 of the stove table.

[0109] After the welding of the supporting structure is completed, the second welding head 22 welds the supporting structure 31 and the tabletop 32. Since the connection between the tabletop 32 and the supporting structure 31 is usually a critical area for welding, the positioning component 13 of the first welding head 12 positions the supporting structure 31 near the second welding guide rail 21, so that the second welding head 22 can perform fine welding on these areas, thereby ensuring the strength and aesthetics of the weld between the supporting structure 31 and the tabletop 32.

[0110] The beneficial effect of the above-described implementation method is that the method of this application embodiment can significantly improve the welding quality and production efficiency of irregularly shaped stove tables, and meet the market's requirements for aesthetics and functionality.

[0111] In some implementations, the above method further includes: detecting the rotation angle of the welding part 126 by the angle sensor 126a, detecting the vibration state of the welding part 126 by the vibration sensor 126b, and controlling the drive component 122 to stop moving when the rotation angle of the welding part 126 is less than a preset rotation angle, or the vibration amplitude of the welding part 126 is greater than or equal to a preset vibration amplitude.

[0112] During welding, 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 strength and aesthetics of the weld, and can prevent the welding rod of the welding part 126 from getting 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, which causes the rotation angle of the welding part 126 to be too small, which may result in poor welding effect and may cause the welding rod of the welding part 126 to get stuck.

[0113] For example, with 0° as a reference, the angle of rotation can be 20°, where the welding electrode is perpendicular to the side plate of the support structure.

[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 indicates that the vibration amplitude of the welding part 126 is too large, which may lead to a deterioration in welding quality. At this time, the control component 14 can control the drive component to stop moving, thereby avoiding deviations or welding quality problems during the welding process.

[0115] The beneficial effects of the above implementation method are that by detecting the rotation angle of the welding part and the vibration of the welding part through the angle sensor, it is possible to avoid the welding rod being too short and the vibration amplitude during the welding process being too large. This achieves high-precision and high-efficiency welding of irregularly shaped furnace tables and solves the problem that traditional welding methods are difficult to deal with complex shapes and high-temperature deformation.

[0116] In some implementations, the above method further includes: detecting the sequential tilt angle of the fixing frame 121 by tilt sensor 121a, detecting the distance from the first welding head 12 to the tabletop 32 by distance sensor 126c, wherein the tilt angle change value of adjacent tilt angles in the sequential tilt angle is less than a preset tilt angle change value, and when the distances from multiple first welding heads 12 to the tabletop 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 tabletop 32.

[0117] During welding, the timing tilt angle of the fixture 121 can be detected by the tilt sensor 121a. The timing tilt angle is the tilt angle detected at multiple times, and the welding state can be determined by the timing tilt angle.

[0118] For example, the timing tilt angle can be the tilt angle of the fixture 121 at 1 second intervals.

[0119] During welding, if the change in tilt angle between adjacent tilt angles in the sequential tilt angle is less than the preset change in tilt angle, it indicates that the tilt angle of the fixed frame 121 has not changed abruptly, meaning that the welding process of the multiple first welding heads 12 on the support structure 31 is relatively stable.

[0120] During welding, the distance between the first welding head 12 and the tabletop 32 can be detected by the distance sensor 126c. When the welding process of the multiple first welding heads 12 on the support structure 31 is relatively stable, and when the distance between the multiple first welding heads 12 and the tabletop 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 tabletop 32. Thus, the support structure 31 and the tabletop 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 implementation method is that by detecting whether the welding process of multiple first welding heads is relatively stable in the process of supporting the structure, and when the distance from multiple first welding heads to the table is less than the preset distance, the support structure and the table 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.

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