[0022] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0024] For smaller production workshops, manual welding is often used to solder the back surfaces of multiple capacitors. This involves welding multiple capacitors in series using welding wire to create larger capacitor components. This method requires the capacitor to be placed directly under the welding torch. The operator positions the capacitor with one hand and the welding wire with the other, relying entirely on the welder's experience. This can easily lead to inaccurate positioning, causing the weld point to deviate from the welding line. Manual and visual control of welding position results in poor stability and consistency, making weld quality difficult to guarantee.

[0025] In order to solve the above problems, refer to the attached Figure 1 -Attached Figure 5 A capacitor welding auxiliary device includes a rotating table 1, a fixed plate 2, a first telescopic rod 7 and a guide ring 8. The rotating table 1 is provided with a limiting groove 101, the capacitor 3 is placed in the limiting groove 101, the fixed plate 2 further fixes the capacitor 3, the welding gun 4 is placed directly above the capacitor 3, and also includes a welding wire 6. A welding head 5 is installed at the lower end of the welding gun 4, and the welding wire 6 can be welded to a predetermined position on the upper end of the capacitor 3 through the welding head 5.

[0026] The welding line 6 passes through the guide ring 8 and is manually welded to the first point of the capacitor 3. The rotation of the rotating table 1 drives the capacitor 3 to rotate. The first telescopic rod 7 controls the position of the welding line 6 by telescoping. With the cooperation of the rotating table 1, the first telescopic rod 7 and the guide ring 8, the welding of the remaining points is completed.

[0027] The above steps can be found in the attached Figure 3 and attached Figure 4After the first point is welded and fixed, the welding and fixing of subsequent points can be completed by adjusting the rotation angle of the rotating table 1 (usually 90°) and the extension length of the first telescopic rod 7.

[0028] Before controlling the rotation of the rotating table 1, it is necessary to first weld and fix the welding wire 6 to the lower end capacitor 3 to ensure the stable welding state of this section of the welding wire 6; the welding gun 4 here can be controlled by an existing multi-joint manipulator, which can adjust the welding gun 4 to a predetermined position to complete continuous and automatic welding fixation.

[0029] In summary, through the above-mentioned structural design, the rotation position of multiple capacitors 3 can be controlled by controlling the rotating table 1, and the welding position of the welding line 6 can be controlled by the first telescopic rod 7 and the guide ring 8. Through the cooperation of the two, the welding position between the welding line 6 and the capacitor 3 can be adjusted to realize automatic welding of multiple capacitors 3; through the above-mentioned structural design, the welding position can be accurately positioned, the welding quality can be improved, and at the same time, the manual workload can be reduced and the work efficiency can be improved.

[0030] Furthermore, in order to achieve fully automatic welding, a position control device 11 is also included. The telescopic end of the position control device 11 is equipped with a traction end 10, and a wire cutting device 9 is installed on the outside of the traction end 10; the wire cutting device 9 can cut off the welded welding wire 6, and the traction end 10 can clamp and pull the cut welding wire 6. The position control device 11 here includes a second telescopic rod and an electric rail. The electric rail and the second telescopic rod can adjust the position of the traction end 10 and the wire cutting device 9, and can further guide the welding wire 6 while pulling the end of the welding wire 6 to a predetermined position to complete the welding.

[0031] The traction end 10 here can be selected as a clamping device for rollers, which can clamp the welding line 6 while conveying it forward a certain distance, and can be staggered with the wire cutting device 9 to ensure the continuity of welding.

[0032] The wire cutting device 9 here can be selected as a common shearing device, ensuring that two shearing blades are arranged opposite to each other to achieve rapid shearing of the welding line 6.

[0033] The guide ring 8 here can be selected as a common circular guide ring, which can guide the welding line 6 and reduce the wear on the surface of the welding line 6.

[0034] The welding gun 4 moves with the rotation of the rotating table 1 to precisely locate the position of the capacitor 3; the position control device 11, the first telescopic rod 7, the wire cutting device 9, and the traction end 10 are all electrically connected, which can accurately control the position of the welding line 6 and perform precise cutting.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
