Description

Technical Field

[0001] The utility model relates to the technical field of switch power supply production, in particular to a soldering device for a switch power supply transformer. Background Art

[0002] A switching power supply transformer is a power transformer with a switching tube added. In addition to the voltage conversion function of an ordinary transformer in the circuit, it also has insulation isolation and power transmission functions. It is generally used in switching power supplies and other occasions involving high-frequency circuits. During the processing and production process, whether it is the assembly of the transformer itself or the mounting of the transformer and the switching power supply motherboard, soldering equipment is required for welding.

[0003] The current soldering equipment, in actual use, will have certain work obstacles after the workpiece is fixed, and the angle of the soldering head needs to be constantly adjusted. For example, after the transformer and the motherboard are mounted, the pins are at the angle between the motherboard and the side surface of the transformer body. The transformer body and the motherboard will hinder the movement of the solder head. It is necessary to change the cutting angle of the solder head, which will hinder the soldering work.
