Description

Technical Field

[0001] This invention belongs to the field of welding technology, and specifically relates to a welding device. Background Technology

[0002] Tank structures, as a common container structure, are widely used in daily life and industrial production. During the manufacturing process of tank structures, it is often necessary to assemble a head structure with a cylindrical structure, and then weld along the seam at the joint to secure the head structure to the cylindrical joint. For example, in the manufacturing process of a water heater's inner tank, two head structures need to be joined and welded together to form the inner tank of the water heater.

[0003] In related technologies, the welding process for the inner tank structure of water heaters requires manually positioning and aligning the left and right end caps, and then welding them together using a handheld welding torch. However, manually welding the inner tank of a water heater is labor-intensive, and the welding quality varies greatly among different workers, leading to a low yield rate in the manufacturing process of the inner tank. Summary of the Invention

[0004] To address the aforementioned problems, namely the difficulty in welding tank structures in related technologies, this invention provides a welding device.

[0005] This welding equipment can be used to weld two parts. The equipment includes a machine base, a first positioning mechanism, a second positioning mechanism, and a welding device.

The first and second positioning mechanisms are opposite to each other, and the first positioning mechanism can move closer to or further away from the second positioning mechanism. The welding device is movably mounted on the machine base and can switch between a first position and a second position relative to the machine base. When the two parts to be welded are joined and the welding device moves to the first position, the welding device abuts against the joint of the two parts.

The fourth driving member is rotatably connected to the swing arm, and the fourth driving member drives the swing arm to rotate between a third position and a fourth position. When the swing arm rotates to the third position, the first positioning member is located between the first positioning mechanism and the second positioning mechanism, and the first positioning member is opposite to the first positioning mechanism or the second positioning mechanism. When the swing arm rotates to the fourth position, the first positioning member moves out of the gap between the first positioning mechanism and the second positioning mechanism.

[0012] In the preferred embodiment of the above welding equipment, the welding equipment further includes a second feeding mechanism. The second feeding mechanism has a first mounting frame and a third gripper. The third gripper is movably disposed on the first mounting frame and moves relative to the first mounting frame between a fifth position and a sixth position. When the third gripper moves to the fifth position, the third gripper is opposite to a preset temporary storage area. The preset temporary storage area is used to place the workpiece to be welded, and the third gripper is used to grip the workpiece to be welded located in the preset temporary storage area.

The first and second positioning mechanisms are opposite each other and can move closer or further apart, allowing the two parts to be welded, mounted on the first and second positioning mechanisms, to approach and connect. The welding device can move between a first position and a second position, allowing the welding component to move closer to the connection point of the two parts to be welded, so that it can be used to weld both parts. Thus, this welding equipment can automatically weld two parts, thereby reducing labor intensity and welding difficulty during the welding process. Furthermore, during the welding process, the distance between the welding device and the connection point of the two parts to be welded remains constant, which helps improve the consistency of welding quality for different products and increases the yield rate in the product manufacturing process.

Detailed Implementation

[0031] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although the welding equipment of the present invention is described in conjunction with the welding assembly of a water heater inner tank, this is not limiting; other products requiring circumferential welding of two components can also use the welding equipment provided by the present invention. For example, the welding equipment provided by the present invention can also be used for welding storage tanks, shaft welding, etc.

[0032] Secondly, it should be noted that in the description of this invention, terms such as "inner" and "outer" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.

[0033] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] In related technologies, the welding process for water heater inner tanks requires manual alignment of two end cap structures before welding them together using a handheld welding torch. This manual welding process involves manually joining the two end caps, resulting in high labor intensity and low welding efficiency. Furthermore, inconsistent welding quality from different individuals leads to varying product quality for the water heater inner tanks, reducing the consistency and yield rate of products manufactured during production. Additionally, burrs on the end cap structures during production can easily cause cuts to workers. Moreover, the dust and fumes generated during welding can easily cause pneumoconiosis and other diseases among workers.

[0035] To address the aforementioned technical problems, this application provides a welding device. This welding device can be used to weld two end caps in the inner tank of a water heater. The welding device includes two positioning mechanisms for fixing the end caps of the water heater inner tank. The two positioning mechanisms are arranged opposite to each other on a machine base, and at least one of the positioning mechanisms can move relative to the machine base, allowing the two positioning mechanisms to move closer or further apart. Specifically, the two positioning mechanisms can be moved further apart to provide sufficient installation space between them for installing the end caps of the water heater inner tank. The welding device also includes a welding apparatus, which is movably mounted on the machine base. Specifically, the welding apparatus can move closer to or further away from the mating position of the two end caps. For example, when welding is required, the welding apparatus moves closer to the mating position of the two end caps until it can weld the mating point. After welding is completed, the welding apparatus moves away from the mating point of the two end caps, stopping the welding. In this way, the welding device can achieve automatic welding of the end caps of the water heater inner tank, thereby helping to solve the problems of high welding difficulty, low welding efficiency, and low yield rate of water heater inner tank end caps. Furthermore, welding the inner tank end cap of the water heater using this welding equipment can avoid harming the health of the workers.

[0036] The following is combined Figures 1 to 12 The preferred technical solution of the welding equipment of the present invention is described.

[0037] The welding equipment provided in this application can be used to weld two parts 10 to be welded. For example, the two parts 10 to be welded can be columnar or cylindrical structures. For example, the parts 10 to be welded can be two end caps in the inner tank of a water heater.

[0038] Reference Figure 1 and Figure 2 The welding equipment provided in this application includes a machine base 100, a first positioning mechanism 200, a second positioning mechanism 300, and a welding device 400. The machine base 100 serves as a basic structure, providing a mounting base for other components. The first positioning mechanism 200 is used to fix one of the two parts 10 to be welded. The second positioning mechanism 300 is used to fix the other of the two parts 10 to be welded.

[0039] In some optional embodiments, reference is made to Figure 1 At least one of the first positioning mechanism 200 and the second positioning mechanism 300 is movably disposed on the machine base 100. The first positioning mechanism 200 and the second positioning mechanism 300 are opposite to each other, and the first positioning mechanism 200 can move closer to or further away from the second positioning mechanism 300.

[0040] Reference Figure 1 In some optional embodiments, the first positioning mechanism 200 and the second positioning mechanism 300 are arranged at intervals along a first direction. Exemplarily, both the first positioning mechanism 200 and the second positioning mechanism 300 can move relative to the machine tool 100 along the first direction. In some optional embodiments, a linear guide rail is provided on the machine tool 100, and both the first positioning mechanism 200 and the second positioning mechanism 300 are movably mounted on the linear guide rail, so that both the first positioning mechanism 200 and the second positioning mechanism 300 can slide along the linear guide rail. Optionally, the first direction can be... Figure 1 The direction indicated by the x-axis.

[0041] Reference Figure 1 and Figure 6 For example, of the two parts 10 to be welded, one is assembled onto the first positioning mechanism 200, and the other is assembled onto the second positioning mechanism 300. The first positioning mechanism 200 and the second positioning mechanism 300 are opposite each other, that is, the end of the part 10 to be welded on the first positioning mechanism 200 is opposite to the end of the part 10 to be welded on the second positioning mechanism 300. In this way, by bringing the first positioning mechanism 200 closer to the second positioning mechanism 300, the part 10 to be welded on the first positioning mechanism 200 can be mated with the part 10 to be welded on the second positioning mechanism 300.

[0042] Reference Figure 4 and Figure 5 According to some optional embodiments, the welding device 400 is movably disposed on the machine base 100, and the welding device 400 switches between a first position and a second position relative to the machine base 100. When two parts 10 to be welded are joined and the welding device 400 moves to the first position, the welding device 400 abuts against the joint of the two parts 10 to be welded, so that the welding device 400 can perform welding on the joint of the two parts 10 to be welded. When the two parts 10 to be welded are joined and the welding device 400 moves to the second position, the welding device 400 separates from the joint of the two parts 10 to be welded. Optionally, the welding device 400 can be, but is not limited to, a welding torch.

[0043] In the welding equipment provided above, the first positioning mechanism 200 and the second positioning mechanism 300 can automatically align two parts 10 to be welded. By controlling the movement of the welding device 400 relative to the machine base 100, the position of the welding device 400 relative to the parts 10 to be welded is adjusted, thereby enabling the welding device 400 to automatically weld the two parts 10. For example, the welding equipment provided in the above embodiment can be used to weld two end caps in the inner tank of a water heater, thereby reducing the difficulty of welding the end caps of the water heater inner tank and improving the yield rate of the water heater inner tank.

[0044] For example, the welding equipment described above can be used, but is not limited to, for spot welding of the assembly gap between two parts 10 to be welded.

[0045] In some alternative embodiments, an annular assembly gap is formed at the joint of the two parts 10 to be welded. The direction of movement of the welding device 400 relative to the machine base 100 is radial to the annular assembly gap. In this way, parts 10 of different diameters can be welded depending on the range of movement of the welding device 400 relative to the machine base 100.

[0046] In some optional embodiments, the welding equipment includes a plurality of welding devices 400. Optionally, the welding devices 400 are spaced apart along the extension direction of the weld seam at the butt joint of the two parts 10 to be welded. (Refer to...) Figure 4 When an annular assembly gap is formed at the joint of two parts 10 to be welded, multiple welding devices 400 are distributed at intervals around the joint of the two parts 10 to be welded.

[0047] For example, during the welding process of two parts 10 to be welded, multiple parts 10 to be welded can be simultaneously controlled to move in a direction close to or away from the joint of the two parts 10 to be welded, so as to realize that multiple welding devices 400 simultaneously weld the two parts 10 to be welded. In this way, the simultaneous welding of multiple welding devices 400 is beneficial to improving the welding and assembly efficiency of the two parts 10 to be welded.

[0048] Reference Figure 1 , Figure 6 and Figure 7 In some optional embodiments, the first positioning mechanism 200 includes a first gripper 210, a first mounting base 220, and a first drive member. Exemplarily, the first mounting base 220 is a basic structural component that can provide a mounting base for the first gripper 210.

[0049] In some optional embodiments, the first mounting base 220 is movably disposed on the machine base 100. For example, one of the first mounting base 220 and the machine base 100 is provided with a guide rail, and the other is provided with a slider that slides with the guide rail, so that the first mounting base 220 can slide relative to the machine base 100 along the guide rail.

[0050] In some alternative embodiments, the first gripper 210 is rotatably connected to the first mounting base 220. A first drive member is disposed on the first mounting base 220. The first drive member is connected to the first gripper 210, and the first drive member drives the first gripper 210 to rotate about a first axis. When the workpiece 10 to be welded is assembled to the first gripper 210, the first axis is the axis of rotation of the workpiece 10 to be welded.

[0051] In the above embodiments, the first gripper 210 can be used to clamp and fix the workpiece 10 to be welded. The first driving member drives the first gripper 210 to rotate, thereby causing the workpiece 10 assembled on the first gripper 210 to rotate. For example, during the welding process of two workpieces 10, the first driving member can be used to provide power for the two workpieces 10 to rotate around their own axis, thereby enabling the welding device 400 to perform welding at different positions at the joint of the two workpieces 10. In some optional embodiments, the first driving member can be, but is not limited to, a motor or a hydraulic motor.

[0052] Reference Figure 2 and Figure 4 In some optional embodiments, the second positioning mechanism 300 includes a second gripper 310, a second mounting base 320, and a second drive member. The second mounting base 320 is a basic structural component that provides a mounting foundation for the second gripper 310 and the second drive member.

[0053] In some optional embodiments, the second mounting base 320 is movably disposed on the machine base 100. Exemplarily, one of the second mounting base 320 and the machine base 100 is provided with a guide rail, and the other is provided with a slider that slides along the guide rail, so that the second mounting base 320 can slide relative to the machine base 100 along the guide rail. In some optional embodiments, the second mounting base 320 and the first mounting base 220 can slide along the same guide rail on the machine base 100, so that the first mounting base 220 and the second mounting base 320 can move closer to or further apart from each other along the same guide rail on the machine base 100.

[0054] In some optional embodiments, the second gripper 310 is rotatably connected to the second mounting base 320. The second drive member is connected to the second gripper 310 and drives the second gripper 310 to rotate about a second axis. When the workpiece 10 to be welded is assembled to the second gripper 310, the second axis is the axis of rotation of the workpiece 10 to be welded.

[0055] In the above embodiment, the second gripper 310 can be used to clamp and fix the workpiece 10 to be welded. The second driving member drives the second gripper 310 to rotate, thereby causing the workpiece 10 assembled on the second gripper 310 to rotate. For example, during the welding process of two workpieces 10, the second driving member can be used to provide power for the two workpieces 10 to rotate around their own axis, thereby enabling the welding device 400 to perform welding at different positions at the joint of the two workpieces 10.

[0056] In some optional embodiments, the first jaw 210 and the second jaw 310 are coaxially arranged, that is, the workpiece 10 to be welded assembled on the first jaw 210 and the workpiece 10 to be welded assembled on the second jaw 310 are coaxial, so as to facilitate the docking of the two workpieces 10 and improve the docking accuracy of the two workpieces 10.

[0057] In some optional embodiments, the first positioning mechanism 200 and the second positioning mechanism 300 are spaced apart on the machine base 100 along a third direction, and the first positioning mechanism 200 and / or the second positioning mechanism 300 can move relative to the machine base 100 along the third direction, so that the first positioning mechanism 200 and the second positioning mechanism 300 can move closer or further apart relative to each other. For example, the axis of the first gripper 210 in the first positioning mechanism 200 and the axis of the second gripper 310 in the second positioning mechanism 300 are both parallel to the third direction. This is beneficial for improving the docking accuracy of the two parts 10 to be welded. Optionally, the third direction can be... Figure 1 The direction indicated by the x-axis.

[0058] In some alternative embodiments, a plurality of welding devices 400 are evenly distributed around the joint of the two parts 10 to be welded. For example, see... Figure 4 The welding equipment includes three welding devices 400, which are spaced apart along the outer periphery of the connection between the two parts 10 to be welded, and the central angle between two adjacent welding devices 400 is 30°. Thus, during the electric welding of the water heater head by the welding devices 400, the two parts 10 to be welded can be rotated 90° each time by the first driving component.

[0059] For example, when two parts 10 need to be welded, multiple welding devices 400 can be used to form multiple weld points at the initial positions of the two parts 10. Further, the first positioning mechanism 200 and the second positioning mechanism 300 are used to rotate the two parts 10 by 90°. Further, the multiple welding devices 400 are used to perform spot welding on the two parts 10 again. In this way, three welding devices 400 can be used to perform four spot welding operations, achieving 12 weld points distributed at intervals along the joint of the two parts 10, thus improving welding efficiency.

[0060] As some optional embodiments, the first gripper 210 and the second gripper 310 can be, but are not limited to, gripping mechanisms in the prior art that can be used to grip cylindrical or cylindrical objects. Therefore, the embodiments of this application do not limit the specific structure of the first gripper 210 and the second gripper 310.

[0061] In some alternative embodiments, refer to Figure 8 The welding equipment also includes a sixth driving component 500. The sixth driving component 500 is disposed on the machine base 100. The sixth driving component 500 is connected to the first positioning mechanism 200 and / or the second positioning mechanism 300, and the sixth driving component 500 drives the first positioning mechanism 200 and the second positioning mechanism 300 to move closer to or further away from each other.

[0062] In some alternative embodiments, the welding equipment includes two sixth drive members 500. Exemplarily, one of the two sixth drive members 500 is connected to the first positioning mechanism 200 and the other is connected to the second positioning mechanism 300, thereby enabling the first positioning mechanism 200 and the second positioning mechanism 300 to move independently relative to the machine base 100.

[0063] In optional embodiments, the sixth driving component 500 may be, but is not limited to, a cylinder, a hydraulic cylinder, a lead screw mechanism, a gear and rack mechanism, a cam mechanism, etc. Therefore, the specific structure of the sixth driving component 500 is not limited in the embodiments of this application.

[0064] In the above embodiments, the sixth driving member 500 can drive the first positioning mechanism 200 to move closer to or further away from the second positioning mechanism 300, thereby enabling the welding parts 10 on the first positioning mechanism 200 and the welding parts 10 on the second positioning mechanism 300 to dock, thus eliminating the need for operators to manually move the two welding parts 10 and reducing the labor intensity of operators.

[0065] In some alternative embodiments, refer to Figure 4 and Figure 5 The welding equipment also includes a third mounting base 600 and a third drive unit 700. Exemplarily, the third mounting base 600 is a basic structural component that can provide a mounting base for the third drive unit 700 and the welding device 400.

[0066] For example, the third mounting base 600 is connected to the machine base 100. The welding device 400 is movably disposed on the third mounting base 600. The third drive member 700 is connected to the welding device 400, and the third drive member 700 drives the welding device 400 to move between a first position and a second position.

[0067] In some optional embodiments, a guide rail is provided on the third mounting base 600, and the welding device 400 slides in cooperation with the guide rail on the third mounting base 600 so that the third driving member 700 can drive the welding device 400 to slide relative to the third mounting base 600 along the guide rail.

[0068] In some optional embodiments, the third drive member 700 may be, but is not limited to, a cylinder, a hydraulic cylinder, a lead screw mechanism, a gear and rack mechanism, a cam mechanism, etc. Therefore, the embodiments of this application do not limit the specific structure of the third drive member 700.

[0069] According to some optional embodiments, the extension direction of the linear guide rail on the third mounting base 600 that slides with the welding device 400 is perpendicular to the axes of the first gripper 210 and the second gripper 310, and the extension direction of the linear guide rail on the third mounting base 600 that slides with the welding device 400 intersects the axial direction of the second gripper 310. In this way, when the welding equipment is used to weld parts 10 of different diameters, it is beneficial to maintain a constant angle between the welding device 400 and the tangential plane at the welding position of the part 10, thereby ensuring consistent welding quality.

[0070] In some alternative embodiments, refer to Figures 1 to 4 as well as Figure 8 and Figure 9 The welding equipment also includes a first feeding mechanism 800. Exemplarily, the first feeding mechanism 800 is used to assemble the workpiece 10 to be welded onto the first positioning mechanism 200 and / or the second positioning mechanism 300. In some optional embodiments, the welding equipment includes two first feeding mechanisms 800, one of which corresponds to the first positioning mechanism 200 for assembling the workpiece 10 to be welded onto the first positioning mechanism 200, and the other corresponds to the second positioning mechanism 300 for assembling the workpiece 10 to be welded onto the second positioning mechanism 300.

[0071] In the above embodiments, the first feeding mechanism 800 can be used to assemble the workpiece 10 to be welded to the first positioning mechanism 200 and / or the second positioning mechanism 300, thereby avoiding manual assembly of the workpiece 10 to be welded, which is beneficial to prevent burrs on the workpiece 10 from injuring the operators and reducing the labor intensity of the operators.

[0072] In some optional embodiments, both the first positioning mechanism 200 and the second positioning mechanism 300 are movably mounted on the machine base 100. During the process of assembling the workpiece 10 to be welded onto the welding equipment, the first positioning mechanism 200 and the second positioning mechanism 300 can be driven to move away from each other synchronously, providing sufficient clearance for the two first feeding mechanisms 800 to assemble the workpiece 10 to be welded.

[0073] In some alternative embodiments, such as Figure 9 As shown, the first feeding mechanism 800 includes a fourth mounting base 810, a swing arm 820, a first positioning member 830, and a fourth driving member 840. The fourth mounting base 810 is a basic structural component that provides a mounting base for the swing arm 820, the first positioning member 830, and / or the fourth driving member 840. The first positioning member 830 is used to fix the corresponding workpiece 10 to be welded.

[0074] Reference Figure 1 , Figure 8 and Figure 9 A fourth mounting base 810 is disposed on the machine base 100. The first end of the swing arm 820 is rotatably connected to the fourth mounting base 810. The second end of the swing arm 820 is connected to the first positioning member 830. A fourth driving member 840 is rotatably connected to the swing arm 820, and the fourth driving member 840 drives the swing arm 820 to rotate between a third position and a fourth position. When the swing arm 820 rotates to the third position, the first positioning member 830 is located between the first positioning mechanism 200 and the second positioning mechanism 300, and is opposite to either the first positioning mechanism 200 or the second positioning mechanism 300. When the swing arm 820 rotates to the fourth position, the first positioning member 830 moves out of the gap between the first positioning mechanism 200 and the second positioning mechanism 300.

[0075] In the welding equipment provided in the above embodiments, the fourth driving member 840 can drive the swing arm 820 to rotate around the first end of the swing arm 820, thereby driving the first positioning member 830 at the second end of the swing arm 820 and the workpiece 10 to be welded assembled on the first positioning member 830 to move.

[0076] In some alternative embodiments, the first feeding mechanism 800 further includes a gear reducer. Exemplarily, the gear reducer is disposed between the fourth drive member 840 and the swing arm 820. This is beneficial for increasing the maximum torque output by the swing arm 820 and reducing the load on the fourth drive member 840.

[0077] In some optional embodiments, the first loading mechanism 800 further includes a fifth driving member. The fourth mounting seat 810 is movably arranged on the machine table 100. The fifth driving member is connected to the fourth mounting seat 810, and the fifth driving member drives the fourth mounting seat 810 to move in a first direction, where the first direction is the axial direction of the workpiece to be welded 10 assembled on the first positioning member 830. Exemplarily, the first direction is Figure 1 the direction shown by the x-axis in

[0078] In the above embodiments, the fourth mounting seat 810 is movably arranged on the machine table 100. Furthermore, the workpiece to be welded 10 on the first loading mechanism 800 can be moved by the relative movement of the fourth mounting seat 810 with respect to the machine table 100, so that the workpiece to be welded 10 can be assembled on the first positioning member 830. And the workpiece to be welded 10 on the first loading mechanism 800 is moved by the relative movement of the fourth mounting seat 810 with respect to the machine table 100, so that the workpiece to be welded 10 on the first positioning member 830 can be assembled on the first positioning mechanism 200 or the second positioning mechanism 300. Of course, in some optional embodiments, the workpiece to be welded 10 can also be transferred from the first positioning member 830 to the first positioning mechanism 200 or the second positioning mechanism 300 by the relative movement of the first positioning mechanism 200 or the second positioning mechanism 300 with respect to the machine table 100.

[0079] In some optional embodiments, the workpiece to be welded 10 is the head structure of a water heater inner tank. When the workpiece to be welded 10 is assembled on the first positioning member 830, at least part of the first positioning member 830 is embedded in the workpiece to be welded 10. In a further optional embodiment, the first jaw 210 and / or the second jaw 310 fix the workpiece to be welded 10 by clamping the outer peripheral wall of the workpiece to be welded 10.

[0080] According to some optional embodiments, referring to Figure 1 and Figure 2 , the welding equipment further includes a second loading mechanism 900. Exemplarily, the second loading mechanism 900 can be used to move the workpiece to be welded 10 on the production line to the picking position of the first loading mechanism 800.

[0081] Referring to Figure 1 , in some optional embodiments, the welding equipment includes two second loading mechanisms 900. Exemplarily, one second loading mechanism 900 corresponds to one first loading mechanism 800. In this way, the welding equipment can assemble the workpiece to be welded 10 on the production line to the first positioning mechanism 200 or the second positioning mechanism 300 through the second loading mechanism 900 and the first loading mechanism 800.

[0082] Refer to Figure 3 , Figure 4 and Figures 6 to 9According to some optional embodiments, the second feeding mechanism 900 has a first mounting bracket 910 and a third gripper 920. The first mounting bracket 910 can provide a mounting base for the third gripper 920. (Refer to...) Figure 7 and Figure 8 The third gripper 920 is movably disposed on the first mounting bracket 910, and the third gripper 920 moves relative to the first mounting bracket 910 between a fifth position and a sixth position. When the third gripper 920 moves to the fifth position, the third gripper 920 is opposite to a preset temporary storage area. The preset temporary storage area is used to place the workpiece 10 to be welded. For example, the preset temporary storage area may be, but is not limited to, a conveyor belt for transporting the workpiece 10 to be welded. The third gripper 920 is used to grip the workpiece 10 to be welded located in the preset temporary storage area. When the third gripper 920 moves to the sixth position and the swing arm 820 rotates to the fourth position, the third gripper 920 is opposite to the first positioning member 830, so that the first loading mechanism 800 can pick up or place the workpiece 10 to be welded on the third gripper 920.

[0083] like Figure 3 , Figure 6 , Figure 8 and Figure 9 As shown, the third gripper 920 is opposite to the first positioning member 830, and the workpiece 10 to be welded, which is assembled onto the third gripper 920, is coaxial with the first positioning member 830. Further optionally, by driving the first loading mechanism 800 to move relative to the machine base 100, the first positioning member 830 can be assembled with the workpiece 10 to be welded on the third gripper 920. Then, the third gripper 920 is released, thereby transferring the workpiece 10 to be welded onto the first positioning member 830. Then, the first loading mechanism 800 assembles the workpiece 10 to be welded onto the first positioning mechanism 200 or the second positioning mechanism 300.

[0084] In some optional embodiments, a guide rail is provided on the first mounting bracket 910, and the third gripper 920 is slidably engaged with the guide rail so that the third gripper 920 can slide along the guide rail.

[0085] Reference Figure 10 and Figure 11 In some optional embodiments, the third gripper 920 includes a fifth mounting base 921, a gripping assembly 922, and a seventh drive member 923. The fifth mounting base 921 is a basic structural component that provides a mounting base for the gripping assembly 922 and the seventh drive member 923.

[0086] like Figure 10 and Figure 11As shown, the clamping assembly 922 is rotatably connected to the fifth mounting base 921. A seventh driving member 923 is disposed on the fifth mounting base 921. The seventh driving member 923 is connected to the clamping assembly 922, and drives the clamping assembly 922 to rotate between a seventh position and an eighth position. Optionally, the seventh driving member 923 can be, but is not limited to, a motor, hydraulic cylinder, pneumatic cylinder, cam mechanism, etc.

[0087] Optionally, the structure of the clamping assembly 922 can be configured differently depending on the structure and size of the workpiece 10 to be welded. For example, if the workpiece 10 to be welded is cylindrical or cylindrical, the clamping assembly 922 may include at least two clamping arms to clamp the outer peripheral wall of the workpiece 10 to be welded, thereby fixing the workpiece 10 to be welded.

[0088] Reference Figure 10 When the clamping assembly 922 is rotated to the seventh position, the clamping assembly 922 is oriented in a first direction. For example, the first direction may be, but is not limited to, a vertical direction.

[0089] Reference Figure 11 When the clamping assembly 922 is rotated to the eighth position, the clamping assembly 922 faces the second direction, which intersects the first direction. For example, the second direction can be, but is not limited to, a horizontal direction. Optionally, the first and second directions can be perpendicular.

[0090] In some optional embodiments, the test piece is the end cap of a water heater inner tank. During the transport of the water heater inner tank on the production line, the axial direction of the end cap is vertical. However, during the welding of two end caps, the axial direction of the two end caps is horizontal.

[0091] In the above embodiments, the third gripper 920 can not only be used to hold the workpiece 10 to be welded, but also the direction of the third gripper 920 can be adjusted to adapt to the posture needs of the workpiece 10 to be welded before and during welding.

[0092] Reference Figure 7 In some optional embodiments, the third gripper 920 includes a ninth drive member 924. Exemplarily, the ninth drive member 924 is connected to both the fifth mounting base 921 and the first mounting bracket 910, and the ninth drive member 924 can drive the fifth mounting base 921 to move relative to the first mounting bracket 910 between a fifth position and a sixth position. In some optional embodiments, the ninth drive member 924 can be, but is not limited to, a rack and pinion mechanism, a lead screw mechanism, a cylinder, or a hydraulic cylinder.

[0093] In some alternative embodiments, the fifth mounting base 921 includes a first sub-base and a second sub-base. The first sub-base is movably disposed on the first mounting bracket 910. The second sub-base is movably disposed on the first sub-base and is vertically movable relative to the first sub-base. Exemplarily, a seventh drive member 923 and a clamping assembly 922 are disposed on the second sub-base, and the seventh drive member 923 and the clamping assembly 922 are vertically movable relative to the first sub-base along with the second sub-base.

[0094] In some further optional embodiments, the third gripper 920 also includes a tenth drive member 925. Optionally, the tenth drive member 925 is connected to the first sub-base and the second sub-base respectively, and the tenth drive member 925 drives the second sub-base to rise or fall vertically relative to the first sub-base. Exemplarily, the tenth drive member 925 can be, but is not limited to, a cylinder or a hydraulic cylinder.

[0095] In the above embodiments, the third gripper 920 can hold the workpiece 10 to be welded and raise or lower it so that the third gripper 920 can pick up and put the workpiece 10 to be welded.

[0096] Reference Figures 1 to 4 The welding equipment also includes a third positioning mechanism 1000. Exemplarily, the third positioning mechanism 1000 is located between a fifth position and a sixth position, allowing the second feeding mechanism 900 to transfer the workpiece 10 to be welded to the third positioning mechanism 1000, ensuring the accuracy of the assembly of the two workpieces 10. Optionally, one third positioning mechanism 1000 corresponds to one second feeding mechanism 900. The third positioning mechanism 1000 is disposed between the fifth and sixth positions where the third gripper 920 of the corresponding second feeding mechanism 900 moves.

[0097] In some alternative embodiments, during the docking process, the two parts to be welded 10 need to be docked in a specific manner. For example, both parts to be welded 10 are provided with assembly structures, and in order for the product formed after the two parts to be welded 10 to be used to assemble other components, it is necessary to ensure that the relative positions between the assembly structures on the two parts to be welded 10 can accommodate the components that need to be assembled subsequently.

[0098] In the above embodiments, the position of the workpiece 10 to be welded can be pre-adjusted by the third positioning mechanism 1000, and then the workpiece 10 to be welded can be assembled onto the first positioning mechanism 200 or the second positioning mechanism 300. This ensures that the relative position parameters between the assembly structures on the two workpieces 10 to be welded are at preset values ​​after the workpieces 10 to be welded on the first positioning mechanism 200 and the second positioning mechanism 300 are aligned. The relative position parameters can be, but are not limited to, angles, spacing, and orientation. Therefore, the welding equipment provided in this embodiment can achieve automatic alignment and assembly of two workpieces 10 to be welded, which is beneficial to improving the accuracy and efficiency of welding assembly of two workpieces 10 to be welded.

[0099] In some optional embodiments, the third positioning mechanism 1000 includes a positioning platform 1010, a second positioning member 1020, an eighth driving member 1030, a detection device 1040, and a controller 1050. The positioning platform 1010 is a basic structural component that provides a mounting base for other components. The second positioning member 1020 is used to assemble the workpiece 10 to be welded. When the workpiece 10 to be welded is assembled to the second positioning member 1020, the second positioning member 1020 is coaxial with the workpiece 10. The second positioning member 1020 is rotatably engaged with the positioning platform 1010. The eighth driving member 1030 is disposed on the positioning platform 1010. The eighth driving member 1030 is connected to the second positioning member 1020, and the eighth driving member 1030 drives the second positioning member 1020 to rotate around its axis.

[0100] For example, the eighth driving member 1030 drives the second positioning member 1020 to rotate around the axis of the second positioning member 1020, thereby causing the workpiece 10 to be welded to rotate around the axis of the second positioning member 1020, and thus adjusting the orientation of the assembly structure in the workpiece 10 to be welded. When the orientation of the assembly structure in the workpiece 10 to be welded rotates to a preset direction, the eighth driving member 1030 can be controlled to stop driving the second positioning member 1020 to rotate. Then, the third gripper 920 clamps the workpiece 10 to be welded on the second positioning member 1020, and the second feeding mechanism 900 and the first feeding mechanism 800 assemble the workpiece 10 to be welded onto the first positioning mechanism 200 or the second positioning mechanism 300. Since the movement trajectory of the second feeding mechanism 900 and the first feeding mechanism 800 assembling the workpiece 10 to be welded from the third positioning mechanism 1000 onto the first positioning mechanism 200 or the second positioning mechanism 300 is a preset movement trajectory. Therefore, the welding equipment can adjust the orientation of the assembly structure in the workpiece 10 to be welded by the third positioning mechanism 1000, and adjust the orientation of the assembly structure of the workpiece 10 to be welded assembled on the first positioning mechanism 200 and the second positioning mechanism 300, so as to ensure that the relative position parameters between the assembly structures on the two workpieces 10 to be welded are to the preset value.

[0101] According to some optional embodiments, refer to Figures 1 to 4as well as Figures 6 to 9 The component 10 to be welded has assembly holes 11. For example, the component 10 to be welded is the end cap of a water heater inner tank. In order to facilitate the subsequent installation of pipes on the water heater inner tank, it is necessary to ensure that the assembly holes 11 on the two end caps of the inner tank are spaced apart along the axial direction of the water heater inner tank.

[0102] Reference Figure 12 In some optional embodiments, the detection device 1040 is disposed on the positioning stage 1010. The detection device 1040 is used to detect the assembly hole 11. The controller 1050 is connected to the eighth drive member 1030 and the detection device 1040, and the controller 1050 controls the eighth drive member 1030 to perform a preset action according to the detection information of the detection device 1040. For example, the detection device 1040 can be, but is not limited to, an infrared sensor. Optionally, when the assembly hole 11 is opposite to the detection device 1040, the controller 1050 controls the eighth drive member 1030 to stop driving the second positioning member 1020 to rotate, so that the assembly hole 11 in the workpiece 10 to be welded faces a preset direction.

[0103] In some alternative embodiments, such as Figure 6 As shown, the third positioning mechanism 1000 also includes a locking member 1060. For example, the locking member 1060 can be connected to the controller 1050. The controller 1050 controls the locking member 1060 to perform a preset action based on the detection information from the detection device 1040. For example, when the assembly hole 11 is opposite to the detection device 1040, the controller 1050 controls the locking member 1060 to engage with the workpiece 10 to be welded, thereby preventing the workpiece 10 from rotating.

[0104] In some alternative embodiments, the locking member 1060 may be a telescopic mechanism. When the mounting hole 11 is opposite to the detection device 1040, the locking member 1060 extends, and at least a portion of the locking member 1060 is embedded in the mounting hole 11 of the workpiece 10 to be welded, thereby locking the workpiece 10 to be welded. When the third gripper 920 grips the workpiece 10 to be welded on the second positioning member 1020, the locking member 1060 retracts to release the locking of the workpiece 10 to be welded.

[0105] For example, the locking element 1060 may be, but is not limited to, a cylinder, a hydraulic cylinder, and / or a cam mechanism.

[0106] In some optional embodiments, the welding equipment further includes an unloading mechanism 1100. Optionally, the unloading mechanism 1100 is used to unload the welded product from the first positioning mechanism 200 and the second positioning mechanism 300.

[0107] Reference Figure 8In some optional embodiments, the unloading mechanism 1100 includes a lifting frame 1110 and a support member 1120. The support member 1120 is used to support the product formed after the two parts to be welded 10 are welded.

[0108] In some optional embodiments, when the product after welding the two parts 10 is a cylindrical or cylindrical structure, the support 1120 has a positioning groove. The opening of the positioning groove faces vertically upward. Optionally, the positioning groove can be, but is not limited to, a V-groove, an arc-shaped groove, and / or a rectangular groove. (Refer to...) Figure 1 For example, two 10-position water heater inner tank end caps are to be welded. The product after welding the two water heaters is a 20-position water heater inner tank.

[0109] Reference Figure 8 The lifting frame 1110 is movably mounted on the machine base 100. For example, the machine base 100 is provided with a guide rail, and the lifting frame 1110 slides with the guide rail so that the lifting frame 1110 can move relative to the machine base 100.

[0110] In an optional embodiment, the lifting frame 1110 switches between a ninth position and a tenth position relative to the machine platform 100. When the lifting frame 1110 moves to the ninth position relative to the machine platform 100 and the two parts 10 to be welded are joined, the support member 1120 is located directly below the parts 10 to be welded. When the lifting frame 1110 moves to the tenth position relative to the machine platform 100, the support member 1120 moves out of the gap between the first positioning mechanism 200 and the second positioning mechanism 300. In an optional embodiment, the support member 1120 is disposed on the lifting frame 1110, and the lifting frame 1110 drives the support member 1120 to rise or fall.

[0111] In the above embodiment, when the lifting frame 1110 moves to the ninth position relative to the machine base 100, the lifting frame 1110 can be raised to lift the welded product. This allows the welded product to be removed from the first positioning mechanism 200 and the second positioning mechanism 300. Then, the lifting frame 1110 is controlled to move to the tenth position so that the welded product is moved out of the gap between the first positioning mechanism 200 and the second positioning mechanism 300.

[0112] Reference Figure 8In some optional embodiments, the unloading mechanism 1100 further includes an unloading component 1130. Optionally, the unloading component 1130 includes a first unloading plate and a second unloading plate. The first unloading plate and the second unloading plate are spaced apart on the machine base 100. In some optional embodiments, when the lifting frame 1110 is in the tenth position, the lifting frame 1110 is located between the first unloading plate and the second unloading plate. In some optional embodiments, the top of both the first unloading plate and the second unloading plate is provided with a support surface. Exemplarily, the height of the support surface of the unloading component 1130 from the side near the first positioning mechanism 200 to the side away from the first positioning mechanism 200 gradually decreases from the machine base 100. Thus, when the lifting frame 1110 moves to the tenth position, the height of the lifting frame 1110 decreases so that the product formed after welding is supported on the support surfaces of the first unloading plate and the second unloading plate, so that the product formed after welding can slide down along the support surfaces of the first unloading plate and the second unloading plate.

[0113] In summary, the welding equipment provided by some optional embodiments of the present invention can align two parts 10 to be welded without requiring operators to move them, thereby reducing the labor intensity of operators. Furthermore, the welding device 400 can move relative to the machine base 100, eliminating the need for operators to hold the welding device 400, thus preventing harmful gases or dust generated during welding from damaging the health of operators. Moreover, the distance between the welding device 400 and the first positioning mechanism 200 and the second positioning mechanism 300 can be set according to the structure and size of the two parts 10 to be welded, which helps maintain the welding angle and welding time during the welding process, thereby improving the consistency of welding quality for different products and increasing the product yield.

[0114] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.
