Abstract

The invention relates to a method and device for soldering tin by induction heating of a magnetism collecting rod, and relates to the field of electronic appliances and electromechanical industries which requires a soldering technology. The defects of a conventional technology using soldering iron for soldering tin are overcome, a high-frequency power supply is adopted to provide a high-frequencyworking power supply for an induction coil to generate a high-frequency alternating magnetic field inside the induction coil, the magnetism collecting rod is used to transfer energy of the high-frequency alternating magnetic field inside the induction coil to a soldering position and a soldered tin wire, and with the adoption of an electromagnetic principle, heat energy generated by eddy current formed on the metal surface by magnetic lines is used to weld. Compared with the prior art, the method and the device have the following advantages that 1, the welding consistency is better; 2, the production efficiency is improved; 3, energy is transferred in a more concentrated manner; 4, more energy is saved; and 5, a high-frequency welding process has no consumables, but soldering with a soldering bit needs to frequently replace a soldering iron nozzle, so that the production cost is reduced more with the high-frequency welding process.
