The invention relates to an automatic assembling machine of an inductor. The automatic assembling machine comprises a rack and a distribution control box; a conveying device is arranged on the rack; a loading and unloading device is arranged at the upper middle part of the conveying device; a sheet inserting device of an iron sheet is arranged on the left side of the conveying device; a ring pressing device and a core inserting device of an iron core are arranged on the right side of the conveying device; the loading and unloading device is composed of a charging disc arranged on the rack; the charging disc is matched with a loading conveying groove and an unloading conveying groove which are formed in the rack through a fetching device; and the loading conveying groove and the unloading conveying groove are matched with a conveying carrier on a conveying chain through a transferring device. According to the automatic assembling machine, with adoption of the conveying chain which runs anticlockwise as a conveying part, a loading station can be arranged adjacent to an unloading station; and meanwhile, with equipment of a matched loading and unloading station and adoption of the same charge disc as a skeleton and a finished product loading part, integral operation of the loading and unloading is realized, the assembly efficiency is greatly improved, the occupying space is saved, and the energy consumption in the conveying process is reduced.
