A plurality of uniformly distributed medicine holding grooves are arranged on the turntable inner core 9 in the circumferential direction. An injection opening is provided in the circumferential direction of the turntable outer shell 8, and the plate medicine is put into the medicine holding grooves of the turntable inner core 9 through the injection opening. The first motor 11 drives the turntable inner core 9 to rotate, so as to put the plate medicine in the corresponding medicine holding groove.

[0026] The pallet clamping module 7 includes a first screw rod stepping motor 701, a gear 702, a second motor 703, a rack clamping rod 704, a clamping pallet 705, a screw nut 706, a motor L-shaped bracket 707, and a limit cover 708. The second motor 703 is fixed on the motor L-shaped bracket 707, and the motor L-shaped bracket 707 is fixed on the clamping pallet 705. The output shaft of the second motor 703 is fixedly connected to the gear 702 to drive the gear 702 to rotate. The rack clamping rod 704 is also L-shaped, and an inclined groove 709 is provided at its top. The rack at the bottom of the rack clamping rod 704 meshes with the gear 702. The screw nut 706 is fixed on the clamping pallet 705. The first screw rod stepping motor 701 is supported on the box body bottom plate 2, and the screw rod thereon passes through the clamping pallet 705 and realizes the vertical up and down movement of the entire pallet clamping module by meshing with the screw nut 706. Through the cooperation of the rack and the gear 702, the rack clamping rod moves relative to the clamping pallet 705, so that the lower part of the plate medicine is fixed by the inclined groove 709, and both sides are clamped by the rack clamping rod 704 and the clamping pallet 705. The limit cover 708 is fixed at the end of the clamping pallet 705 and is used to limit the rack.

[0028] A layer of clean and environmentally friendly film material is laid in the medicine outlet box 1 to solve the pollution problem when the tablets fall.

[0029] Among them, the first cylinder and the second cylinder can also be replaced by a lead screw slide table, which greatly improves the positioning accuracy on the X-axis on the original basis.

[0030] The gear rack can also be replaced by a cylinder to perform reciprocating motion to realize the clamping action on the side of the medicine plate, sharing a common air source with the original cylinder, which is more cost-saving.

[0031] In order to remind the elderly to take medicine, a buzzer is installed at the medicine outlet of the drawer. If the medicine at the medicine outlet in the drawer has not been taken by the elderly all the time, it will make a sound to remind and ensure that the elderly take medicine on time.

[0032] The working principle of the present invention is as follows:

[0033] The plate-packed medicine is put into the medicine holding groove of the inner core 9 of the grooved turntable from the upper hole. The turntable housing 8 remains fixed. The first motor 11 precisely controls the rotation through the intermediate shaft, so that the medicine in the specified groove reaches the pallet clamping module 7. The first lead screw stepper motor 701 of the pallet clamping module 7 makes the clamping pallet 705 move to the specified position. The pallet clamping module 7 clamps both sides of the edge of the medicine plate. The Openmv camera 12 takes pictures and processes the pictures, converts to obtain the medicine tablet distribution coordinates, determines the movement time and distance of each component module. The first cylinder 5 and the second cylinder 3 move to the specified coordinates through the xy-axis. Subsequently, the second lead screw stepper motor 1305 of the medicine extrusion module 13 makes the medicine extrusion module 13 contact and press the plate-packed medicine. The medicine extrusion rod 1303 moves driven by the second cylinder 3, extrudes the tablets out. The tablets fall into the lower medicine outlet box 1, and the medicine outlet box 1 can be opened to take the medicine, or the set parameters can be changed to change the number of tablets.
