The present disclosure relates to a micro light emitting diode (Micro LED) transfer-printing device. A heating device and a movable cooling device are arranged on a rack, wherein a cooling surface of the cooling device is opposite to a heating surface of the heating device. A roller mechanism is arranged between the heating device and the cooling device, and a cyclically rotatable conveyor belt is configured on the roller mechanism. A temperature control glue is configured on an outer surface of the conveyor belt. Compared with the conventional solution, the proposed Micro LED transfer-printing device realizes cyclic absorption and transfer-printing of the Micro LED such that the transfer-printing efficiency may be enhanced.
