Abstract:
1. A transformer core manufacturing apparatus for manufacturing an annular transformer core having thin plates formed of magnetic materials laminated, comprising: an uncoiler unit which allows a plurality of uncoilers each having a thin plate magnetic material coiled hoop-like to uncoil the magnetic material; a carrier unit for guiding a plurality of the magnetic materials uncoiled from the plurality of the uncoilers as a single group of magnetic body; a first alignment unit for aligning the carried group of the single magnetic body in a width direction; a cut-off unit for cutting the magnetic body aligned by the first alignment unit in a predetermined dimension; a laminating unit for laminating a plurality of the groups of the magnetic body cut by the cut-off unit; a second alignment unit for aligning the magnetic body laminated on the laminating unit in the width direction; and a control unit for controlling operations of the uncoiler unit, the carrier unit, the first alignment unit, the cut-off unit, the laminating unit, and the second alignment unit, wherein the first alignment unit is provided with at least one of a lateral vibration unit for vibrating the magnetic body in the width direction and a vertical vibration unit for vibrating the magnetic body in a laminating direction.
