The invention discloses an automatic conveying mechanism of new energy motor rotor magnetic steel. The automatic conveying mechanism comprises a magnetic steel stock bin, an X-direction pushing mechanism, a first discharging mechanism, a Y-direction pushing mechanism and a second discharging mechanism. The magnetic steel stock bin is used for containing a magnetic steel plate. The X-direction pushing mechanism is used for pushing the magnetic steel plate to move in the X direction. The first discharging mechanism is used for pushing a row of magnetic steel strips at the foremost end of the magnetic steel plate to be separated from the magnetic steel plate. The Y-direction pushing mechanism is used for pushing the magnetic steel strips to move in the Y direction. The second discharging mechanism is used for separating magnetic steel sheets at the foremost ends of the magnetic steel strips from the magnetic steel strips. By means of the magnetic steel stock bin, one magnetic steel plate can be fed at a time, the number of materials is large, the working efficiency is greatly improved, and following full-automatic assembly is possible; through the cooperation of a magnetic steel pushing plate and a first magnetic steel separation tool, the magnetic steel plate can be split into the magnetic steel strips; and through the cooperation of a magnetic steel pushing block and a separation pressing head, the magnetic steel sheets can be separated from the magnetic steel strips and pushed into a motor rotor, and the purpose of automatically conveying the magnetic steel is achieved.
