Technical Field

[0001] The utility model relates to the technical field of capacitor processing, in particular to a spot welding device for capacitor production and processing. Background Art

[0002] Two conductors placed close together with a non-conductive dielectric in between form a capacitor. When a voltage is applied between the two plates of a capacitor, the capacitor stores an electric charge.

[0003] Capacitors require spot welding equipment during production and processing. Traditional spot welding equipment uses mobile feeding, and the welding point is easily deviated during the movement of the material, resulting in unstable welding. In addition, the welding gun needs maintenance and inspection after a period of use. The traditional welding gun is fixed to the body with bolts, which is not convenient for disassembly and assembly, and is inconvenient to use. Utility Model Content

[0013] (3) Beneficial effects

[0014] Compared with the prior art, the present invention provides a spot welding device for capacitor production and processing, which has the following beneficial effects:

[0015] This spot welding device for capacitor production and processing consists of a lifting assembly consisting of a back plate, a top plate, and a lifter. The lifter passes through the center of the top plate and is connected to the slide frame, which can adjust the height of the slide frame and thus achieve stable spot welding operations.

[0016] The adjustment assembly consists of a sliding frame, threaded rod, slider, and motor. The motor drives the threaded rod to rotate, allowing the slider to move precisely within the slot of the sliding frame. This allows the horizontal position of the welding gun to be fine-tuned according to the specific position of the capacitor, ensuring the accuracy of the spot welding position.

[0017] The design of the connector makes assembly and disassembly of the welding gun very convenient. By turning the handle, the worm rotates, which in turn rotates the meshing worm wheel. The positive and negative threaded screws in the center of the worm wheel rotate accordingly, driving the clamping block to move within the movable groove, engaging or disengaging the clamping blocks on both sides of the connecting groove. This solves the problem of the traditional welding gun and slider being connected by bolts and inconvenient to assemble and disassemble. BRIEF DESCRIPTION OF THE DRAWINGS

The lifter 4 adopts a hydraulic cylinder with stable operation.

[0026] During actual use, in order to facilitate the disassembly and assembly of the welding gun 9 so as to carry out regular maintenance and inspection, in this embodiment, the connecting member includes a connecting seat 11, a worm 12, a worm wheel 13, a positive and negative thread screw 14, a block 15 and a handle 16.
