Among them, the accompanying drawings form a part of the present invention and are used together with the embodiments of the present invention to explain the principle of the present invention, rather than to limit the scope of the present invention.

[0045] A specific embodiment of the present invention, as Figures 1 - 16 shown, discloses a drug storage and dispensing device, which is particularly suitable for drugs that need to be refrigerated, such as vaccines. As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the drug storage and dispensing device includes a support frame 1, an upper drawer mechanism 2, and a lower drawer mechanism 3. The upper drawer mechanism 2 is located above the lower drawer mechanism 3. Both the upper drawer mechanism 2 and the lower drawer mechanism 3 are connected to the support frame 1 and can slide along the support frame 1. When not dispensing drugs, the storage spaces of both the upper drawer mechanism 2 and the lower drawer mechanism 3 are located in the cold storage.

[0046] As Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, the support frame 1 includes first support columns 11, support crossbeams 12, and second support columns 13. There are multiple first support columns 11 and second support columns 13. Both ends of the support crossbeam 12 are respectively connected to a first support column 11 to form an H-shaped support frame. The number of H-shaped support frames is determined by the length of the lower drawer mechanism 3, and there are at least two H-shaped support frames. The second support columns 13 are arranged above the first support columns 11.

[0047] For installing the upper drawer mechanism 2 and the lower drawer mechanism 3, as Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, the support frame 1 further includes a first U-shaped plate frame 14 and a second U-shaped plate frame 15. The first U-shaped plate frame 14 includes a first U-shaped plate 141 and a first connecting plate 142. The first connecting plate 142 is arranged along the length direction of the first U-shaped plate 141.

The second U-shaped plate frame 15 includes a second U-shaped plate 151 and a second connecting plate 152. The second connecting plate 152 is arranged along the length direction of the second U-shaped plate 151. The second connecting plate 152 is arranged on both sides of the top of the second U-shaped plate 151 and is horizontally arranged. The top of the second support column 13 is connected to the first connecting plate 142. The first U-shaped plate 141 is located between the two second support columns 13. The bottom of the second support column 13 is connected to the second connecting plate 152. The top of the first support column 11 is connected to the second connecting plate 152. The second U-shaped plate 151 is located between the two first support columns 11 and is above the support crossbeam 12. It should be noted that both the first U-shaped plate frame 14 and the second U-shaped plate frame 15 are integrally formed by sheet metal.

[0048] As Figure 3 shown, the upper drawer mechanism 2 includes a first drawer 21 and a first driving component 22. Part of the first drawer 21 is located within the first U-shaped plate 141. The first driving component 22 is used to drive the first drawer 21 to move along the first U-shaped plate 141. Understandably, as Figure 7 and Figure 11As shown, the upper drawer mechanism 2 further includes two first slide rails 23 which are provided on two side walls of the first drawer 21. The support frame 1 further includes two first slideways 16 which are provided on two inner side walls of the first U-shaped plate 141. The first slide rails 23 slide along the first slideways 16.

[0049] As Figure 9 and Figure 10 shown, the first driving assembly 22 includes a first motor 221, a first pulley 222, a first belt 223, a second pulley 224 and a first rotating shaft 225. The first pulley 222 is connected to the output shaft of the first motor 221. The first rotating shaft 225 is rotatably connected to the bottom plate of the first U-shaped plate 141. The second pulley 224 is connected to the first rotating shaft 225. The first belt 223 connects the first pulley 222 and the second pulley 224. Driven by the first motor 221, the first rotating shaft 225 rotates.

[0050] As Figure 7 and Figure 8 shown, the first driving assembly 22 further includes a third pulley 226, a second belt 227, a fourth pulley 228 and a second rotating shaft 229. The third pulley 226 is connected to the first rotating shaft 225. The second pulley 224 and the third pulley 226 are respectively located on two sides of the bottom plate of the first U-shaped plate 141. The second rotating shaft 229 is rotatably connected to the bottom plate of the first U-shaped plate 141. The fourth pulley 228 is connected to the second rotating shaft 229. The second belt 227 connects the third pulley 226 and the fourth pulley 228. The fourth pulley 228 and the third pulley 226 are located on the same side of the bottom plate of the first U-shaped plate 141.

[0051] As Figure 8 and Figure 9 shown, the first driving assembly 22 further includes a third connecting plate 230 and a fourth connecting plate 231. One end of the third connecting plate 230 is connected to the rear end of the first drawer 21. The other end of the third connecting plate 230 is connected to one end of the fourth connecting plate 231. The other end of the fourth connecting plate 231 is connected to the second belt 227. The first motor 221 drives the first rotating shaft 225 to rotate through the first pulley 222, the first belt 223 and the second pulley 224. The rotation of the first rotating shaft 225 is transmitted to the second belt 227 through the third pulley 226 and the fourth pulley 228, thus driving the first drawer 21 to move back and forth.

[0052] In order to control the displacement of the first drawer 21, as Figure 8 and Figure 9As shown, the upper drawer mechanism 2 further includes a first limit switch 24, a second limit switch 25, and a first trigger plate 26. The first limit switch 24 and the second limit switch 25 are both disposed on the bottom plate of the first U-shaped plate 141 and on the same side of the second belt 227. The upper end of the first trigger plate 26 is connected to the third connecting plate 230. When the first drawer 21 reciprocates back and forth, it drives the first trigger plate 26 to reciprocate. When the first trigger plate 26 contacts the first limit switch 24, the first motor 221 stops running. At this time, the first drawer 21 is in the first position, that is, the closed position. When the first trigger plate 26 contacts the second limit switch 25, the first motor 221 stops running. At this time, the first drawer 21 is in the second position, that is, the open position.

[0053] To enable the first rotating shaft 225 to rotate stably, as Figure 9 and Figure 10 shown, the upper drawer mechanism 2 further includes a first mounting seat 27. The first mounting seat 27 is connected to the bottom plate of the first U-shaped plate 141. The upper end of the first rotating shaft 225 is connected to the bottom plate of the first U-shaped plate 141, and the lower end of the first rotating shaft 225 is connected to the first mounting seat 27.

[0054] As Figure 7 shown, the upper drawer mechanism 2 further includes a first locking assembly 28. The first locking assembly 28 includes a first connecting cross beam 281, a first electromagnetic lock 282, and a first locking hook 283. The two ends of the first connecting cross beam 281 are respectively connected to the two side plates of the first U-shaped plate 141. The first electromagnetic lock 282 is disposed in the middle of the first connecting cross beam 281. The first locking hook 283 is connected to the rear end of the first drawer 21. When the first drawer 21 is in the closed position, the iron core of the first electromagnetic lock 282 pops out and passes through the U-shaped space formed by the first locking hook 283, restricting the movement of the first drawer 21 and preventing the first motor 221 from being accidentally triggered to open the first drawer 21. When the first drawer 21 needs to be opened, the iron core of the first electromagnetic lock 282 retracts and disengages from the restriction of the first locking hook 283, and the first drawer 21 can move freely.

[0055] To reduce the impact during the transmission of drugs (such as vaccines), as shown in 7, the upper drawer mechanism 2 further includes a first buffer plate 29. The first buffer plate 29 is disposed at the rear of the first drawer 21 and is inclined from the top to the bottom of the first drawer 21 to buffer the impact during transmission.

[0056] Understandably, as Figure 3 shown, the lower drawer mechanism 3 includes a second drawer 31 and a second driving assembly 32. A part of the second drawer 31 is located within the second U-shaped plate 151. The second driving assembly 32 is used to drive the second drawer 31 to move along the second U-shaped plate 151. Understandably, as Figure 12As shown, the lower drawer mechanism 3 further includes two second slide rails 33 which are provided on two side walls of the second drawer 31. The support frame 1 further includes two second slide ways 17 which are provided on two inner side walls of the second U-shaped plate 151. The second slide rails 33 slide along the second slide ways 17.

[0057] As Figure 14 shown, the second driving component 32 includes a second motor 321, a fifth pulley 322, a third belt 323, a sixth pulley 324 and a third rotating shaft 325. The fifth pulley 322 is connected to the output shaft of the second motor 321. The third rotating shaft 325 is rotatably connected to the bottom plate of the second U-shaped plate 151. The sixth pulley 324 is connected to the third rotating shaft 325. The third belt 323 connects the fifth pulley 322 and the sixth pulley 324. Driven by the second motor 321, the third rotating shaft 325 rotates.

[0058] As Figure 13 shown, the second driving component 32 further includes a seventh pulley 326, a fourth belt 327, an eighth pulley 328 and a fourth rotating shaft 329. The seventh pulley 326 is connected to the third rotating shaft 325. The sixth pulley 324 and the seventh pulley 326 are respectively located on two sides of the bottom plate of the second U-shaped plate 151. The fourth rotating shaft 329 is rotatably connected to the bottom plate of the second U-shaped plate 151. The eighth pulley 328 is connected to the fourth rotating shaft 329. The fourth belt 327 connects the seventh pulley 326 and the eighth pulley 328. The eighth pulley 328 and the seventh pulley 326 are located on the same side of the bottom plate of the second U-shaped plate 151.

[0059] As Figure 13 and Figure 14 shown, the second driving component 32 further includes a fifth connecting plate 330 and a sixth connecting plate 331. One end of the fifth connecting plate 330 is connected to the rear end of the second drawer 31. The other end of the fifth connecting plate 330 is connected to one end of the sixth connecting plate 331. The other end of the sixth connecting plate 331 is connected to the fourth belt 327. The second motor 321 drives the third rotating shaft 325 to rotate through the fifth pulley 322, the third belt 323 and the sixth pulley 324. The rotation of the third rotating shaft 325 is transmitted to the fourth belt 327 through the seventh pulley 326 and the eighth pulley 328, thus driving the second drawer 31 to reciprocate.

[0060] To control the displacement of the second drawer 31, as Figure 13As shown, the lower drawer mechanism 3 further includes a third limit switch 34, a fourth limit switch 35, and a second trigger plate 36. The third limit switch 34 and the fourth limit switch 35 are both disposed on the bottom plate of the second U-shaped plate 151 and on the same side of the fourth belt 327. The upper end of the second trigger plate 36 is connected to the fifth connecting plate 330. When the second drawer 31 reciprocates back and forth, it drives the second trigger plate 36 to reciprocate. When the second trigger plate 36 contacts the third limit switch 34, the second motor 321 stops running. At this time, the second drawer 31 is in the first position, i.e., the closed position. When the second trigger plate 36 contacts the fourth limit switch 35, the second motor 321 stops running. At this time, the second drawer 31 is in the second position, i.e., the open position.

[0061] To enable the stable rotation of the third rotating shaft 325, as Figure 13 and Figure 14 shown, the lower drawer mechanism 3 further includes a second mounting seat 37. The second mounting seat 37 is connected to the bottom plate of the second U-shaped plate 151. The upper end of the third rotating shaft 325 is connected to the bottom plate of the second U-shaped plate 151, and the lower end of the third rotating shaft 325 is connected to the second mounting seat 37.

[0062] As Figure 15 shown, the lower drawer mechanism 3 further includes a second locking assembly 38. The second locking assembly 38 includes a second connecting cross beam 381, a second electromagnetic lock 382, and a second locking hook 383. The two ends of the second connecting cross beam 381 are respectively connected to the two side plates of the second U-shaped plate 151. The second electromagnetic lock 382 is disposed in the middle of the second connecting cross beam 381. The second locking hook 383 is connected to the rear end of the second drawer 31. When the second drawer 31 is in the closed position, the iron core of the second electromagnetic lock 382 pops out and passes through the U-shaped space formed by the second locking hook 383, restricting the movement of the second drawer 31 and preventing the second motor 321 from being accidentally triggered to open the second drawer 31. When it is necessary to open the second drawer 31, the iron core of the second electromagnetic lock 382 retracts, releasing the restriction on the second locking hook 383, and the second drawer 31 can move freely.

[0063] To reduce the impact during the transmission of drugs (such as vaccines), as Figure 12 shown, the lower drawer mechanism 3 further includes a second buffer plate 39. The second buffer plate 39 is disposed at the rear of the second drawer 31 and is inclined from the top to the bottom of the second drawer 31 to buffer the impact during the transmission.

[0064] As Figure 1 、 Figure 3 、 Figure 4 and Figure 16As shown in the figure, the drug storage and dispensing device further includes a drawer end frame 4, which is installed on the wall 100 of the cold storage (such as a concrete wall, a brick wall, a partition wall, etc.). A drawer opening 41 is provided on the drawer end frame 4. Correspondingly, an opening 101 is provided on the wall 100 of the cold storage. The two openings 101 correspond to the positions of the first drawer 21 and the second drawer 31 respectively. The first drawer 21 and the second drawer 31 can respectively extend out from the upper and lower openings 101 and extend out from the drawer opening 41. In order to prevent the cold air in the cold storage from leaking, a sealing strip 102 (such as a sealing rubber strip) is provided around the opening 101. A first cover plate 211 is provided at the front end of the first drawer 21. When the first drawer 21 is in the closed state, the first cover plate 211 can cover the upper sealing strip 102. Similarly, a second cover plate 311 is provided at the front end of the second drawer 31. When the second drawer 31 is in the closed state, the second cover plate 311 can cover the lower sealing strip 102.

[0065] To facilitate reminding the doctor that the first drawer 21 or the second drawer 31 is in the open state, as Figure 1 shown, a light strip 42 is provided on the outer side of the drawer end frame 4. When the first drawer 21 and / or the second drawer 31 is opened, the light strip 42 flashes. When both the first drawer 21 and the second drawer 31 are closed, the light strip 42 is turned off.

[0066] For the drug storage and dispensing device of this embodiment, it can adopt an automatic operation mode or a manual operation mode. Taking vaccines as an example, when adopting the automatic operation mode, after the doctor sends a vaccine-taking request and the AI storage and dispensing robot finishes taking the vaccine, it sends the vaccine to the conveyor belt. After the conveyor belt rotates, the vaccine is sent to the target inoculation table drawer (the first drawer 21, the second drawer 31). After receiving the instruction, the drawer performs an extension action (i.e., controls the operation of the motor), opens the drawer, and sends the vaccine out of the cold storage. At the same time, the light strip 42 on the drawer panel flashes to indicate that the drawer is operating. After the doctor takes the vaccine, it automatically performs a closing and retracting action. During this process, sensors are required. The control process involved in this part is mature prior art and will not be elaborated here; when adopting the manual operation mode, the first drawer 21 and the second drawer 31 are respectively equipped with remote controls to control the opening and closing of the corresponding drawers, that is, the remote control is used to control the operation of the corresponding motors and electromagnetic locks in the upper drawer mechanism 2 or the lower drawer mechanism 3. The control process of this part is also mature prior art and will not be elaborated here.

[0067] It should be noted that the upper drawer (i.e., the first drawer 21) is used to dispense single-dose vaccines, with a fast vaccine-dispensing speed and high reliability. The lower drawer (i.e., the second drawer 31) is used to dispense multi-dose vaccines, and for a multi-dose vaccine, it can be managed and accessed at any time.

[0068] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
