[0019] Example 1 like Figure 1-4 As shown, the capacitor lead welding device proposed in this utility model includes a worktable 1, a support column, a drive assembly, and a clamping assembly. The support column is installed at the top of the workbench 1, and the top bearing of the support column is equipped with a turntable 2 for moving the capacitor around the circumference of the support column during use. The number of clamping components is multiple, and the multiple clamping components are installed at the top edge of the turntable 2 at equal angles. The side of the clamping components is provided with a push component for opening the clamping components in use. The drive component is located below the worktable 1 and extends above the worktable 1 to connect with the worktable 1.

[0020] In this embodiment, a turntable 2 is rotatably mounted on a support column, with multiple clamping components evenly distributed at the top edge of the turntable. Simultaneously, a drive component drives the turntable to rotate, causing the capacitor to move circumferentially around the support column between the various clamping components. This enables automatic switching of the capacitor between different workstations, allowing the capacitor to sequentially complete the loading, welding, and unloading processes. When a clamping component reaches a designated position, a push component extends towards the clamping component and pushes it open, facilitating the rapid clamping and removal of the capacitor. This effectively improves welding efficiency and automation, and avoids the need for a one-to-one correspondence between cylinders and multiple capacitors, resulting in a simpler structure, reduced costs, and a lower burden on the electrical system and reduced maintenance difficulty.

[0021] Example 2 like Figure 4 As shown, the capacitor lead welding device proposed in this utility model differs from the first embodiment in that the support column includes a column body 14 and a fixing plate 7. The column 14 is located at the top of the workbench 1 and is connected to the bearing of the turntable 2; The fixing plate 7 is bolted to the top of the column 14 and located above the turntable 2.

[0022] In an optional embodiment, a rectangular block 17 is provided at the bottom of the fixing plate 7 and a rectangular groove 12 is provided at the top of the column 14. When the fixing plate 7 and the column 14 are installed together, the rectangular block 17 is accommodated in the rectangular groove 12. This is used to limit the rotation of the fixing plate 7 on the column 14 by the cooperation of the rectangular block 17 and the rectangular groove 12 during use, thereby preventing the fixing plate 7 from rotating unnecessarily during use and causing it to fall off.

[0023] In this embodiment, the turntable 2 is supported by the column 14 and rotates on the column 14 via the bearing. At the same time, the detachable fixing plate 7 is provided to facilitate the limiting of the turntable 2 and make the disassembly, maintenance or replacement of the turntable 2 more convenient.

[0024] Example 3 like Figure 1-3 As shown, the capacitor lead welding device proposed in this utility model differs from Embodiment 1 in that the clamping assembly includes a pad 4, a pressure plate 5, a support plate 6, and a tension spring 10. The pad 4 is installed at the top edge of the turntable 2; The support plate 6 is installed on the side of the pad block 4; The pressure plate 5 is rotatably mounted on the top of the support plate 6 and one end extends above the pad 4; The tension spring 10 is located on the side of the pad 4 and is connected to the pressure plate 5 and the turntable 2.

[0025] In an optional embodiment, the middle two sides of the pressure plate 5 are rotatably connected to the support plate 6, and the other end of the pressure plate 5 is bent downwards. The included angle between the two ends of the pressure plate 5 is 120°-150°. This is used so that when in use, the bending structure allows the pushing component to push the other end of the pressure plate 5 to rotate the pressure plate 5 on the support plate 6, so that one end of the pressure plate 5 rotates upwards on the support plate 6, thereby realizing the opening action of the pressure plate 5, making it more convenient to put the capacitor on the pad 4.

[0026] In an optional embodiment, a gasket 3 is provided at one end of the pressure plate 5 and above the pad 4, for elastic buffering when the pressure plate 5 comes into contact with the capacitor during use, so as to protect the outer wall of the capacitor.

[0027] In an optional embodiment, the top of the pad 4 is provided with a holding groove 11 with an opening on the other side. The depth of the holding groove 11 is less than the thickness of the capacitor. This is used to initially position the capacitor during use, making the capacitor more accurate when placed, thereby improving the clamping accuracy and stability.

[0028] In this embodiment, the other end of the pressure plate 5 is pushed towards the support plate 6 by the pushing component, so that the pressure plate 5 rotates on the support plate 6. The pressure plate 5 has an included angle at both ends, so that one end of the pressure plate 5 rotates upward on the support plate 6, thereby realizing the opening action of the pressure plate 5. This allows the capacitor to be placed inside the pad 4, and the pushing component is slowly reset. At the same time, the tension spring 10 drives one end of the pressure plate 5 to rotate downward, and the pressure plate 5 drives the pad 3 to clamp the capacitor, further improving the clamping stability of the clamping component on the capacitor and avoiding damage to the capacitor during the clamping process.

[0029] Example 4 like Figure 1 As shown, the capacitor lead welding device proposed in this utility model differs from the first embodiment in that the pushing component includes a linear driver 8 and a push plate 9. The linear actuator 8 is mounted on the top of the fixed plate 7 and its extended end is arranged towards the edge of the turntable 2. The linear actuator 8 is one of a cylinder, a hydraulic cylinder, and an electric telescopic rod. The push plate 9 is installed at the extended end of the linear driver 8 and contacts the other end of the pressure plate 5.

[0030] In this embodiment, when the turntable 2 drives the capacitor to move around the cylinder 14, when the capacitor is in the loading or unloading position, the extended end of the turntable 2 drives the push plate 9 to move towards the pressure plate 5, so that the push plate 9 pushes the other end of the pressure plate 5 to move towards the support plate 6, so that the pressure plate 5 rotates on the support plate 6, thereby realizing the action of lifting one end of the pressure plate 5 upward, so that the capacitor can be smoothly placed into the pad 4 or taken out from the pad 4.

[0031] Example 5 like Figure 2 and Figure 4 As shown, the capacitor lead welding device proposed in this utility model differs from the first embodiment in that the driving component includes an external gear ring 13, a gear 15, and a motor 16. The external toothed ring 13 is installed at the bottom of the turntable 2 and fitted onto the outside of the column 14; The gear 15 is disposed on the side of the external gear ring 13 and meshes with the external gear ring 13, and the end of the rotating shaft extends through the worktable 1 to the bottom of the worktable 1 and is rotatably connected to the worktable 1. The motor 16 is mounted below the workbench 1 via a bracket and connected to the shaft of the gear 15 via a transmission structure. The bracket is not shown in the figure.

[0032] In this embodiment, the motor 16 drives the gear 15 to rotate on the workbench 1, and the gear 15 meshes with the external gear ring 13 to drive the turntable 2 to rotate on the column 14 through the bearing. This causes the turntable 2 to drive the capacitor to switch sequentially between the loading, welding and unloading stations, further improving the level of automation and work efficiency.

[0033] In this invention, the extended end of the turntable 2 drives the push plate 9 to move towards the pressure plate 5, causing the push plate 9 to push the other end of the pressure plate 5 towards the support plate 6, making the pressure plate 5 rotate on the support plate 6. This lifts one end of the pressure plate 5 upwards, allowing the capacitor to be smoothly placed inside the pad 4. Simultaneously, the turntable 2 drives the push plate 9 to slowly return to its original position, causing the tension spring 10 to drive one end of the pressure plate 5 to rotate downwards. The pressure plate 5 then causes the pad 3 to press the capacitor firmly against the inner side of the pad 4. The motor 16 drives the gear 15 to rotate on the worktable 1, and the gear 15 meshes with the external gear ring 13. The transmission causes the external gear ring 13 to drive the turntable 2 to rotate on the column 14 via bearings. This causes the turntable 2 to sequentially switch between the loading, welding, and unloading stations of the capacitor. At the unloading and loading stations, the linear driver 8, in cooperation with the push plate 9, rotates the pressure plate 5 on the support plate 6, causing one end of the pressure plate 5 to lift upwards, thus allowing the capacitor to be removed or placed in. This completes the automatic unloading and loading of the capacitor, effectively improving welding efficiency and automation. It also avoids the need for a one-to-one correspondence between the cylinder and multiple capacitors, resulting in a simpler structure, reduced cost, and a lower burden on the electrical system and reduced maintenance difficulty.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
