Problems solved by technology

[0002] In the existing electronics industry, when welding high-frequency electronic components, network components, hardware components, inductors, IC cards, mobile phone speakers, sounders, and micro motors, it is often necessary to weld enameled wires and thin metal wires, especially those involving When welding the copper-clad aluminum enameled wire, it is necessary to manually wind the wire for soldering. Since the copper-clad aluminum enameled wire is relatively brittle, it is easy to break the copper-clad aluminum enameled wire. , that is, the electrodes will stick together with the enameled wire, and it is easy to tear off the solder joints, resulting in desoldering. The operation is too complicated and the efficiency is low, and auxiliary solder tin is needed
Due to the influence of the above factors, the electrodes of existing spot welding machines cannot complete the spot welding of copper-clad aluminum enameled wires, and the welding quality is difficult to control

Embodiment approach 1

[0019] Implementation mode one: if figure 1 As shown, the four-head spot welding body includes four cylindrical electrode blocks 1, the ends of the four cylindrical electrode blocks 1 are connected as a whole to form a welding head 2, and the rest of the parts are insulated. The end surface of the welding head 2 is provided with an edge The arc transition zone is coated with a heat cladding layer, the heat-preserving wall is a layer of heat-resistant paint, and the through holes are equilateral quadrilateral through holes. There are four arc transition zones, respectively It is arranged on two sets of opposite sides of the welding head 1, and the four arc transition zones are separated from each other. Except for the welding head 2 , insulating gaps 3 are provided between the remaining parts of the four trapezoidal electrode blocks 1 , and insulating glue 4 is filled in the insulating gaps 3 . The lower end of the insulating gap 3 terminates in a through hole 5, and the dista...

Embodiment approach 2

[0020] Implementation mode two: if figure 2 As shown: the arc transition zone is an annular arc transition zone surrounding the edge of the welding head 2. The annular arc transition zone is arranged on a spherical surface with the center of the end face of the welding head 2 as the center of the sphere. The remaining structures and components are as follows: Embodiment 1, omitted.

Abstract

The invention relates to a four-end spot welding body. An electrode of a conventional spot welding machine is incapable of completing the spot fusion welding of copper-clad aluminium enameled wires, and the welding quality is difficult to control. The four-end spot welding body comprises four cylindrical electrode blocks, wherein the tail ends of the four cylindrical electrode blocks are integrally connected so as to form a welding head, the rest of parts of the four cylindrical electrode blocks are insulated, the end surface of the welding head is provided with an edge and arc transitional bands, the arc transitional bands are coated with a heat retaining layer which is a layer of heat resisting coating, the lower end of an insulation crack ends at a through hole, the distance between the through hole and the lower end surface of the welding head is in the range of 5-10mm, and the through hole is an equilaterally quadrilateral through hole. The four-end spot welding body has the advantages that the four-end spot welding body is simple in structure and convenient to machine, the adhesion phenomenon of the electrode is avoided, and the enameled wires can be protected from being broken by pressing during welding. The four-end spot welding body is suitable for various spot welding machines and is particularly suitable for the welding of the copper-clad aluminium enameled wires.
