Description

Technical Field

[0001] The utility model relates to the technical field of soldering equipment, in particular to automatic soldering equipment for producing PFC inductor coils. Background Art

[0002] PFC inductors are generally used in inductor-compensated PFC circuits and active PFC circuits. Their main function is rectification. In inductor-compensated PFC circuits, the role of the PFC inductor is to cooperate with other components to reduce the phase difference between the fundamental current and voltage of the AC input. The PFC inductor has the functions of a rectifier and a filter. The role of the inductor in the active PFC circuit is actually similar, which is to make the input current, after rectification by the PFC inductor and filtering by the capacitor, tend to be synchronized with the output voltage change, which can effectively reduce the reactive power consumption of electric energy in the inductor and capacitor devices, and achieve the purpose of improving the power factor.

[0003] In the production process of PFC inductor coils, it is necessary to solder the pins of PFC inductor coils. The conventional practice is to solder manually. This method has the disadvantages of low work efficiency and high labor intensity for workers. During soldering, the temperature of the tin furnace is high, and there are safety hazards for workers during the operation. In addition, the product quality of manual operation is completely dependent on the technical level of the operator, and the quality of the product cannot be guaranteed, so the product qualification rate cannot be effectively improved, which indirectly increases the production cost of the product.
