[0026] The driving assembly 22 is disposed on the housing 1 and is used to drive the main assembly 21 to rotate.

[0027] In this embodiment, the tablets are stacked inside the silo 212 on the cartridge 211, and the tablets slide through the ramp 213 into the temporary storage tube 214 and are located on the top of the soft rubber ring 216. The output end of the electric push rod 23 then drives the guide rod 218 to push the tablets downward. The tablets squeeze the soft rubber ring 216 to deform it, so that the tablets can pass through the soft rubber ring 216 and fall into the test tube below through the drug outlet head 215, thereby realizing the one-by-one addition of tablets.

[0028] Specifically, the main body assembly 21 further includes a spring 219 sleeved on the guide rod 218 , and the spring 219 is located between the upper end of the guide rod 218 and the top of the guide cylinder 217 .

[0029] In this embodiment, when the output end of the electric push rod 23 contracts, the rebound pressure of the spring 219 pushes the spring 219 to move upward and reset.

[0030] Specifically, the driving assembly 22 includes a shaft disk 221 rotatably mounted on the lower end of the box body 1 , and the temporary storage cylinder 214 is fixed on the shaft disk 221 . A servo motor 222 is installed at the bottom of the box body 1 and is used to drive the shaft disk 221 to rotate.

[0031] In this embodiment, the servo motor 222 drives the shaft disc 221 to rotate the test tubes placed inside, so that different tablets can be added to each test tube.

[0032] Specifically, the dispensing mechanism 2 further includes a cover plate 24 inserted and installed on the upper end of the box body 1 , and the cover plate 24 covers the upper end of the cartridge 211 .

[0033] In this embodiment, the cover plate 24 is installed on the upper end of the box body 1 to seal the interior thereof; when the cover plate 24 is removed, tablets can be added to the interior of the silo 212 on the cartridge 211 .

[0034] Specifically, the dispensing mechanism 2 further includes a filling port 26 fixed at both ends of the box body 1 and a medicine outlet pipe 27 fixed at the inner end of the filling port 26 .

[0035] In this embodiment, the filling port 26 can be used to connect a liquid medicine storage barrel with a hose, and the liquid medicine can be transported to the filling port 26 by a peristaltic pump and then dripped into the test tubes placed in the test tube tray 25 from the medicine outlet pipe 27.

[0036] Specifically, a supporting frame 3 is fixed inside the box body 1 , a box door 4 is hinged at the front end of the box body 1 , and an observation window 5 is installed inside the box door 4 .

[0037] In this embodiment, the driving assembly 22 is supported by the supporting frame 3 to prevent deformation caused by the electric push rod 23 applying pressure to the driving assembly 22 .

[0038] The working principle and usage process of the present invention are as follows: first, the tablets are stacked inside the silo 212 on the cartridge 211. The tablets slide down the ramp 213 into the temporary storage cylinder 214 and are located on the top of the soft rubber ring 216. Then, the output end of the electric push rod 23 drives the guide rod 218 to push the tablets downward. The tablets squeeze the soft rubber ring 216 to deform it, so that the tablets can pass through the soft rubber ring 216 and fall into the test tube below through the medicine outlet head 215.

[0039] Then, the output end of the electric push rod 23 contracts, and the rebound pressure of the spring 219 pushes the spring 219 upward to reset; the servo motor 222 then drives the shaft disk 221 to rotate the test tubes placed inside, so that the tablets are added to each test tube;

[0040] At the same time, the liquid medicine storage barrel can be connected to the filling port 26 through a hose, and the liquid medicine is transported to the filling port 26 through a peristaltic pump, and then dripped into the test tube placed in the test tube tray 25 from the medicine outlet pipe 27, thereby realizing automatic dispensing of the liquid medicine.
