The invention discloses a slow-descending type automatic sheet sorting
machine, and relates to the field of motor part
processing process equipment. For a long time, the
stator punching sheets with thin thickness and larger diameters are mostly manually sorted, so that the labor intensity is high and the efficiency is low. The slow-descending type automatic sheet sorting
machine comprises a mounting plate, guide pillars and a first
servo motor which are fixed on the mounting plate, a mandrel connected with an output shaft at the upper end of the first
servo motor, a supporting plate capable ofsliding up and down along the guide pillars, and a second
servo motor arranged at the lower end of the mounting plate, wherein the output shaft at the upper end of the second servo motor is connectedwith the supporting plate through a screw rod pair, and the mandrel is driven to rotate by the first servo motor. When the sheets are sorted, the
stator punching sheets are placed in alignment with the mandrel, the mandrel is driven by the first servo motor to drive the
punching sheets to rotate, when the punching sheet positioning notches are aligned with the positioning keys, the punching sheets fall off, and the supporting plate is descended by the thickness of one punching sheet under the effect of the screw rod pair driven by the second servo motor. The automatic sheet sorting of the
stator punching sheets with the thin thickness and the large diameters can be rapidly achieved, and the sheet sorting efficiency is improved.
