Embodiment Construction

[0014] figure 1 Among them, 1 is the welding head, 2 is the main engine, which plays the role of power adjustment; 3 is the machine head, which is installed on the workbench 6, and the machine head includes the welding head clamp 4 and the welding head pressure adjustment device 8, and 5 is the microscope, which can be adjusted by angle Mechanism 11 is installed on the support 7 that is fixed on workbench 6, and 9 is connecting wire, and 10 is pedal switch.

[0015] figure 2 Among them, the welding head is composed of two parallel electrodes 14 made of high-temperature-resistant metal materials, and high-temperature-resistant metal materials such as tungsten and molybdenum can be used. The ends 13 of the two electrodes are in ohmic contact with each other, and the contact resistance is generally ≤200mΩ, while other parts are insulated from each other. 12 between the two parallel electrodes can be bonded with insulating glue.

Abstract

The spot welder is used specially for welding lacquered wire and other metal wires of 0.02-0.80 mm diameter as well as thin metal belt and sheet in similar size directly in electronic industry and microelectronic industry. It consists of three parts including welding head, main unit for controlling power source and machine head comprising welding clamp and pressure regulator. Owing to the special resistance stress contact structure of welding bend tip and proper working current the main unit supplies, the welding of lacquered wire needs no elimination of insulating lacquer in advance and this makes the welding simple and short in welding period.

Description

technical field [0001] The invention relates to a spot welding machine specially provided for the electronic industry and the microelectronic industry, which is most suitable for directly welding enameled wires, thin metal wires or corresponding thin metal strips and metal sheets with wire diameters of φ0.02mm~φ0.80mm. Background technique [0002] Spot welding is a welding process in which a large amount of current passes through two metal bodies to be welded in an instant, and the electric energy is converted into heat energy, and fusion is generated in the two metal bodies. If there is an insulating layer on the surface of the metal to be welded (such as enameled wire), the current cannot pass through the metal body, and spot welding cannot be performed. In the electronics industry and microelectronics industry, it is often necessary to weld fine enameled wires. The currently used spot welding machine consists of three parts: the welding head, the main machine and the mac...
