Abstract: The present invention discloses a medicine dispensing device for distributing medicine pills automatically, comprising a medicine supply system, a sorting system and a control system. The medicine supply system comprises a plurality of medicine supply units. The sorting system comprises a negative pressure medicine receiving mechanism, a camera subsystem, and two temporary storage cabins for medicine dispensing and discarding. The negative pressure medicine receiving mechanism has a negative pressure sucking head for sucking medicine pills. The negative pressure sucking head sucks a single medicine pill from a corresponding medicine supply unit. The camera subsystem captures images of medicine pills and sends the images to the control system. The camera subsystem recognizes the image of sucked medicine pill to identify the type, quantity and integrity of the medicine pill. This device fills the gap of no household automatic oral medicine dispensing device.
