The invention discloses an intelligent precise small-
dose oral medicine dispensing device which comprises an operation table, a balance is fixedly installed on the operation table, a rolling mechanism is arranged at the top of the balance, a
medicine dispensing mechanism is arranged under the rolling mechanism, and a
medicine loading mechanism is arranged on the side, away from the
medicine dispensing mechanism, of the balance. For infant medicine taking, an existing medicine dispensing device cannot achieve precise medicine dispensing, so that tablets are added into a
grinding mechanism, the medicines are crushed through the
grinding mechanism, then crushed tablet
powder is added into a medicine dispensing mechanism, after the medicines are dispensed through the medicine dispensing mechanism, a balance is used for weighing, and after the weight is determined to be accurate through weighing, the medicine dispensing mechanism is used for dispensing the medicines. And the medicine is packaged through the medicine loading mechanism and is distributed to the hands of the patient.
