Problems solved by technology
On the one hand, when the two electrode handles are respectively installed on the welding machine installation part, the two may be relatively twisted, so that the welding part connected between the two is subjected to a twisting force; , there is welding pressure between the welding part and the weldment, so when welding continuously and quickly, the welding part is easily damaged and broken, the number of spot welding is small, and the service life is low, which cannot meet the requirements of automatic line production
In the prior art, there is a design of filling the insulating gap between the two electrode handles with insulating glue, which is generally used for low-efficiency manual spot welding, and the insulating material has an impact on the welding quality of the product during the welding process. Too high, the welding part is easily damaged and loses the welding function, so it cannot be applied to the continuous production of automatic lines

Embodiment Construction
[0014] Such as figure 1 As shown, a spot welding head for welding enameled wire, which is an integral structure, includes two electrode handles 1, an insulating gap 3 is formed between the two electrode handles 1, and the bottom of the two electrode handles 1 passes through the welding part 2 connected together. The insulating gap 3 is integrally provided with a bent strip-shaped reinforced connecting portion 4, the two ends of the reinforced connecting portion 4 are respectively connected to the two electrode handles 1 near the welding portion 2, and by connecting the reinforced connecting portion 4 It is made thin or long so that the resistance of the reinforced connection part 4 is greater than the resistance of the welding part 2. The spot welding head with the above-mentioned structure can be manufactured from a whole piece of tungsten or molybdenum plate through cutting and other operations, which is very easy to realize and can be mass-produced. The reinforced connecti...

The invention discloses a spot welding head for welding enamelled wires. The spot welding head is in an integral part structure and comprises two electrode handle portions, an insulating gap is formed between the two electrode handle portions, the bottoms of the two electrode handle portions are connected together through a welding portion, a reinforcing connection portion in a bent strip shape is integrally arranged in the insulating gap, two ends of the reinforcing connection portions are respectively connected to positions, close to the welding portion, on the two electrode handle portions, and the resistance of the reinforcing connection portion is larger than that of the welding portion. The spot welding head for the welding enamelled wires overcomes defects of the prior art and is stable and simple in structure, long in service life and quite easy to process and manufacture, and welding reliability is guaranteed.
Description
Technical field [0001] The invention relates to the technical field of electronic spot welding machines, and in particular to a spot welding head used in electronic spot welding machines. Background technique [0002] In the electronics and microelectronics industries, electronic spot welding machines are often used to weld enameled wires to various metal layers. This has the advantage of being able to be welded directly without removing the insulating paint. It can be used in the welding of high-frequency communication components and patch transformers. Welding of leads, welding of chip inductor coils, welding of micro speaker leads, welding of buzzer leads, welding of receiver leads, welding of speaker leads, welding of earphone leads, welding of antenna leads, microphones, sounders, Welding of hands-free earphone leads, vibration motor coil welding, micro motors, module components and PCB welding and other contact welding of various small coil electronic components.
