The utility model relates to a vertical winding machine for a three-dimensional wound core amorphous alloy transformer. The vertical winding machine comprises coil molds, rotary gears, a fixing table, wire wheels and a motor. Three vertical iron cores are fixed to the fixing table and sleeved with the detachable coil molds, the upper sides and the lower sides of the coil molds are provided with the rotary gears, the motor is connected with a driving gear, the driving gear is meshed with the rotary gears, wires used for being wound around the coil molds are stored on the wire wheels, and tension used for winding the wires is provided. By the adoption of a vertical winding method, the iron core turnover procedure is omitted, stress received in the horizontal clamping and turnover processes of the iron cores is eliminated, the wires of three phases are wound simultaneously, and the overall winding efficiency of coils is improved.
