Description

Technical Field

[0001] This invention belongs to the field of automated vaccine dispensing technology, and particularly relates to an alternating dispensing method. Background Technology

[0002] Currently, there are various types of vaccines available on the market to prevent human diseases. Children start receiving vaccinations from a young age to prevent the occurrence of certain diseases. Through vaccination, the human body produces antibodies from the source, avoiding the occurrence of diseases and ensuring people's health. Because there are many types of diseases, there are also many types of vaccines. Live vaccines are a type of human vaccine. Live vaccines must be kept at a specified low temperature to maintain their activity for later use. Therefore, live vaccines should be stored or moved in a refrigerator to provide a suitable temperature environment.

[0003] Currently, vaccines used in newly built vaccination stations are mostly delivered to the station drawers in real time via cold storage. This vaccine delivery method avoids the loss of cold air when using a small refrigerator at the vaccination station, thus ensuring the refrigeration effect of the vaccines.

[0004] The real-time delivery of vaccines from cold storage requires the cooperation of cold storage, conveying devices, and vaccine dispensing devices. Existing vaccine dispensing devices mostly convey vaccines to a single drawer at the vaccination station. After the drawer pops out, the vaccine is manually removed. After the vaccine is removed, the conveying device grabs the vaccine needed by the next person and delivers it to the drawer. Since different people need different vaccination times, and most adults are vaccinated quickly, there will be situations where people wait for the vaccine to be dispensed, which seriously affects the vaccination efficiency.

[0005] Therefore, the low efficiency of seedling collection and emergence at existing inoculation stations is a problem that we need to solve. Summary of the Invention

[0006] Based on the above analysis, the present invention aims to provide an alternating drug dispensing method to solve the problems of low inoculation station speed and low seedling emergence efficiency in the prior art.

[0007] The objective of this invention is mainly achieved through the following technical solutions:

[0008] This invention provides an alternating drug delivery method, the specific steps of which include:

[0009] Step 1: The AGV delivery cart transports the vaccine to the drawer shelf of the vaccination table;

[0010] Step 1.1: Those who need to be vaccinated scan the code to fill out a questionnaire and wait in line for their number to be called;

[0011] Step 1.2: The central cold storage places the vaccine into the vaccine-dispensing device on the AGV delivery cart according to the recipient's information;

[0012] Step 1.3: The AGV medicine delivery cart reaches the designated vaccination table via the AGV road board;

[0013] Step 2: The vaccine guide device switches between two electric drawers;

[0014] Step 2.1: The AGV medicine delivery trolley pushes the drawer switching device to switch between the push-lock state and the push-unlock state;

[0015] Step 2.2: When the AGV medicine delivery trolley pushes the drawer switching device to the maximum limit, the positioning elastic pin enters the guide channel through the guide groove of the rotating plate;

[0016] Step 2.3: Switch the electric drawer of the vaccine guide device;

[0017] Step 3: The AGV delivery cart moves away from the drawer shelf and puts the vaccine into the electric drawer;

[0018] When the AGV medicine delivery trolley leaves, the rotating plate of the seedling tilting device rotates due to the limiting of the positioning elastic pin until the positioning elastic pin slides out of the guide channel.

[0019] Step 4: Open the two electric drawers alternately.

[0020] When the dispensing switch is pressed, the two electric drawers for alternating seedling collection open in turn, allowing staff to grab the seedlings.

[0021] Furthermore, the specific steps of step 2.1 include: the AGV medicine delivery trolley pushes the drawer switching active component, causing the drawer switching execution component to switch between a push-lock state and a push-unlock state; when the drawer switching execution component switches to the push-lock state, it can hold the vaccine guide device in place, allowing the vaccine poured out by the vaccine pouring device to enter the upper electric drawer of the two alternating electric drawers through the vaccine guide device; when the drawer switching execution component switches to the push-unlock state, it no longer applies force to the vaccine guide device, allowing the vaccine poured out by the vaccine pouring device to enter the lower electric drawer of the two alternating electric drawers through the vaccine guide device.

[0022] Furthermore, the specific steps for switching the drawer switching actuator to the push-lock state in step 2.1 include: the AGV medicine delivery trolley pushes the rotating roller to slide along the positioning rod; the rotating pressure plate fixedly connected to the rotating roller pushes the guide rail frame to move; the spring pin in the guide rail frame enters the pin groove to prevent it from resetting, thus completing the switch of the drawer switching actuator to the push-lock state.

[0023] Furthermore, the specific steps for switching the drawer switching execution component to the push-unlock state in step 2.1 include: the AGV medicine delivery trolley pushes the rotating roller to slide along the positioning rod; the rotating pressure plate fixedly connected to the rotating roller pushes the relay plate; the relay plate drives the sliding lever to rotate around the central rotating rod; the sliding lever moves the spring pin to make it exit from the pin slot; the guide rail frame resets under the action of the tension spring; and the guide rail frame retracts.

[0024] Furthermore, in step 2.1, when the AGV medicine delivery trolley pushes the rotating roller, the drawer switching active component can switch back and forth between the push belt guide frame and the relay plate. The rotating roller can slide along the positioning rotating rod under the push of the AGV medicine delivery trolley. When the AGV medicine delivery trolley stops pushing, the rotating roller can slide back to its original position and rotate 180 degrees under the action of the compression spring and the limiting elastic block.

[0025] Furthermore, the specific steps of step 2.2 include: while the AGV medicine delivery trolley pushes the drawer switching active component, it drives the rotating plate of the seedling turning device to approach the positioning elastic pin. When the AGV medicine delivery trolley pushes the drawer switching active component to the maximum limit, the positioning elastic pin enters the guide channel through the guide groove of the rotating plate.

[0026] Furthermore, the specific steps of step 2.3 include: when the drawer switching actuator switches from the push-lock state to the push-unlock state, the hollow telescopic mother plate is no longer limited by the drawer switching actuator, and the telescopic daughter plate slides out from the hollow telescopic mother plate under the action of gravity. One end of the telescopic daughter plate slides along the guide rail under the action of the guide block until the telescopic daughter plate contacts the limiting rod. At this time, the vaccine poured out by the vaccine pouring device enters the lower electric drawer of the two alternating vaccine receiving electric drawers through the vaccine guide device.

[0027] When the drawer switching actuator switches from the push-unlock state to the push-lock state, the hollow telescopic mother plate is pushed by the drawer switching actuator, causing the hollow telescopic mother plate to rotate. The hollow telescopic mother plate drives the telescopic daughter plate to rotate. While rotating under the limit of the guide block and guide rail, the telescopic daughter plate slides into the hollow telescopic mother plate until the drawer switching actuator reaches the maximum limit. At this time, the hollow telescopic mother plate and the telescopic daughter plate stop moving. The vaccine poured out by the vaccine pouring device enters the upper electric drawer of the two alternating vaccine receiving electric drawers through the vaccine guide device.

[0028] Furthermore, the specific steps of step 3 include: the AGV medicine delivery trolley moves away from the drawer frame, thereby causing the vaccine tilting device installed on the AGV medicine delivery trolley to move away from the drawer frame; during the process of the vaccine tilting box moving away from the drawer frame, the positioning elastic pin pressed into the guide channel of the rotating plate plays a limiting role on the rotating plate, causing the rotating plate to rotate; the rotating plate drives the vaccine tilting box to rotate; the vaccine in the vaccine tilting box falls into the vaccine guiding device under the action of gravity; when the AGV medicine delivery trolley moves away until the rotating rod is no longer limited by the positioning elastic pin, the rotating plate and the vaccine tilting box are reset under the action of the first self-rebound rotating shaft.

[0029] Furthermore, the drawer switching device described in step 2.1 includes a drawer switching active component and a drawer switching execution component; the drawer switching active component, under the push of the AGV medicine delivery trolley, can put the drawer switching execution component into a push-lock state or a push-unlock state.

[0030] Furthermore, the drawer switching active component includes a rotating roller, a limiting elastic block, a positioning rod, a pressure spring, a first fixed plate, and a rotating pressure plate; one end of the positioning rod is fixed to the middle side of the first fixed plate, and the other end of the positioning rod is connected to the slidable and rotatable rotating pressure plate, the rotating pressure plate is fixedly connected to the rotating roller, the pressure spring is sleeved on the outer side of the positioning rod, the limiting elastic block is pressed into the groove of the rotating roller, the rotating roller can slide along the positioning rod under the push of the AGV medicine delivery cart, and the rotating roller can slide back to its original position and rotate 180 degrees under the action of the pressure spring and the limiting elastic block when the AGV medicine delivery cart stops pushing.

[0031] Both the rotating roller and the rotating pressure plate have circular grooves in their middle sections for sliding and rotating relative to the positioning rod.

[0032] One end of the compression spring is fixed to the first fixed plate, and the other end of the compression spring is mounted on the rotating pressure plate through a bearing seat.

[0033] One end of the limiting elastic block is fixed to the drawer frame, and the other end of the limiting elastic block can be extended and pressed into the groove of the rotating roller.

[0034] Furthermore, the surface of the rotating roller is provided with two symmetrical straight grooves parallel to the center line of the positioning rod. The head of one of the straight grooves is connected to the tail of the other straight groove through an arc-shaped groove on the surface of the rotating roller. When the AGV medicine delivery trolley pushes the rotating roller, the limiting elastic block moves from the head to the tail of the straight groove and enters the arc-shaped groove. When the AGV medicine delivery trolley stops pushing the rotating roller, under the action of the compression spring and the limiting elastic block, the limiting elastic block moves from the head to the tail of the arc-shaped groove and enters the straight groove.

[0035] The head of the straight groove is slightly lower than the tail of the arc-shaped groove, and the tail of the straight groove is slightly higher than the head of the arc-shaped groove.

[0036] Furthermore, the drawer switching actuator includes a central rotating rod, a sliding lever, a relay plate, a pin-grooved block, a guide block, a guide rail frame, a tension spring, a second fixing plate, and spring pins; one end of the tension spring is fixed in the middle of the second fixing plate, and the other end of the tension spring is fixedly connected to the guide rail frame; the guide rail frame has spring pins on both sides, and the guide rail frame can enter the groove of the pin-grooved block when moving; the guide block is fixed on the pin-grooved block, and the guide block is slidably connected to the rail of the guide rail frame; the central rotating rod has a self-rotating function, and sliding levers that can be inserted into the gap between the pin-grooved block and the guide rail frame are fixed on both sides of the central rotating rod; the lower parts of the two sliding levers are connected by a relay plate.

[0037] The second fixing plate is fixedly connected to the drawer frame.

[0038] The two sides of the central rotating rod are hinged to the drawer frame.

[0039] When the rotating pressure plate pushes the guide rail frame to insert the spring pin into the pin slot, the rotating pressure plate can abut against the vaccine guide device, so that when the vaccine is poured into the vaccine guide device, it will enter the electric drawer in the middle.

[0040] When the rotating pressure plate pushes the relay plate to rotate the sliding lever, the sliding lever can pull the spring pin out of the pin slot. At this time, the guide rail frame is reset under the action of the tension spring and no longer limits the vaccine guide device, so that when the vaccine is poured into the vaccine guide device, it will enter the electric drawer at the bottom.

[0041] Furthermore, the vaccine guiding device includes a hollow telescopic mother plate, a telescopic daughter plate, guide blocks, guide rails, and a limiting rod; one end of the hollow telescopic mother plate is hinged to the drawer frame via a rod, and the telescopic daughter plate is installed inside the hollow telescopic mother plate. The guide blocks are respectively hinged to both sides of one end of the telescopic daughter plate, the guide blocks are slidably connected to the guide rails, and the limiting rods are fixed between the guide rails.

[0042] The guide rail is fixedly connected to the drawer frame.

[0043] When the telescopic subplate contacts the limiting rod, the vaccine poured into the vaccine guide device will enter the lowest electric drawer.

[0044] Furthermore, the vaccine tilting device includes a positioning elastic pin, a rotating plate, a tilting box, an inlet groove, and a guide channel. The upper end of the AGV delivery cart is hinged to one end of the rotating plate via a first self-rebound pivot. The other end of the rotating plate is fixedly connected to the tilting box. The rotating plate has the inlet groove and the guide channel. When the AGV delivery cart moves to a position where the drawer switching actuator is in a push-lock or push-unlock state, the positioning elastic pin can enter the guide channel through the inlet groove. When the AGV delivery cart completes the state switching of the drawer switching actuator and drives away, the positioning elastic pin limits the rotating plate through the guide channel, causing the rotating plate to rotate and thus tilting the vaccine towards the vaccine guide device.

[0045] One end of the positioning elastic pin is fixed to the drawer frame, and the other end of the positioning elastic pin is a retractable pin body used to enter the inlet groove and the guide channel.

[0046] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0047] 1. The alternating dispensing method provided by the present invention enables vaccines to be alternately placed into two electric drawers through the setting of AGV drug delivery cart, vaccine tilting device, drawer switching device and vaccine guiding device. The electric drawers are arranged vertically, which can greatly improve the vaccination efficiency without affecting the legroom of medical staff.

[0048] 2. The alternating dispensing method provided by the present invention uses a straight groove and an arc groove on the surface of the rotating roller. Each time the AGV medicine delivery trolley pushes the rotating roller, the rotating roller slides first, which then drives the rotating pressure plate to switch the state of the drawer switching execution component. After the switching is completed, the AGV medicine delivery trolley drives away. During the driving away process, the rotating roller rotates 180° to switch the direction of the rotating pressure plate. At the same time, the vaccine pouring device works to put the vaccine into the electric drawer through the vaccine guide device.

[0049] 3. The alternating drug dispensing method provided by this invention automates the switching of electric drawers and the dispensing of vaccines in the AGV drug delivery cart, the vaccine pouring device, the drawer switching device, and the vaccine guiding device, without requiring manual intervention. In addition, no electricity is required except for the AGV drug delivery cart, which greatly facilitates the transformation of the existing environment of the disease control vaccination hall.

[0067] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of the present invention and, together with the embodiments of the present invention, serve to illustrate the principles of the present invention.

[0068] This embodiment provides an alternating drug delivery method, such as... Figure 1 , Figure 2 and Figure 3 As shown, the specific steps include:

[0069] Step 1: The AGV delivery cart 6 transports the vaccine to the drawer shelf 4 of the vaccination table 1;

[0070] Step 1.1: Those who need to be vaccinated scan the code to fill out a questionnaire and wait in line for their number to be called;

[0071] Step 1.2: The central cold storage places the vaccine into the vaccine dispensing device 7 on the AGV delivery cart 6 according to the recipient's information;

[0072] Step 1.3: The AGV medicine delivery cart 6 travels through the AGV road board 3 to the designated vaccination table 1;

[0073] Step 2: The vaccine guide device 9 switches between the two electric drawers 5;

[0074] Step 2.1: The AGV medicine delivery cart 6 pushes the drawer switching device 8 to switch between the push-lock state and the push-unlock state;

[0075] Step 2.2: When the AGV medicine delivery trolley 6 pushes the drawer switching device 8 to the maximum limit, the positioning elastic pin 701 enters the guide channel 705 through the guide groove 704 of the rotating plate 702;

[0076] Step 2.3: The vaccine guide device 9 switches the electric drawer 5 to the guide;

[0077] Step 3: The AGV medicine delivery cart 6 moves away from the drawer shelf 4 and puts the vaccine into the electric drawer 5;

[0078] When the AGV medicine delivery trolley 6 drives away, the rotating plate 702 of the seedling tilting device 7 rotates due to the limiting of the positioning elastic pin 701 until the positioning elastic pin 701 slides out from the guide channel 705.

[0079] Step 4: Open the two electric drawers 5 alternately.

[0080] When the dispensing switch is pressed, the two electric drawers 5 that alternately receive seedlings open, allowing staff to grab the seedlings.

[0081] Preferably, step 2.1 includes the following steps: the AGV delivery trolley 6 pushes the drawer switching active component 81, causing the drawer switching execution component 82 to switch between a push-lock state and a push-unlock state; when the drawer switching execution component 82 switches to the push-lock state, it can hold the vaccine guide device 9, allowing the vaccine poured out by the vaccine pouring device 7 to enter the upper electric drawer 5 of the two alternating vaccine receiving electric drawers 5 through the vaccine guide device 9; when the drawer switching execution component 82 switches to the push-unlock state, it no longer applies force to the vaccine guide device 9, allowing the vaccine poured out by the vaccine pouring device 7 to enter the lower electric drawer 5 of the two alternating vaccine receiving electric drawers 5 through the vaccine guide device 9.

[0082] Preferably, the specific steps for the drawer switching actuator 82 to switch to the push-lock state in step 2.1 include: the AGV medicine delivery trolley 6 pushes the rotating roller 811 to slide along the positioning rod 813; the rotating pressure plate 816 fixedly connected to the rotating roller 811 pushes the guide rail frame 826 to move; the spring pin 829 in the guide rail frame 826 enters the pin groove block 824 to prevent it from resetting, thus completing the switch of the drawer switching actuator 82 to the push-lock state.

[0083] Preferably, the specific steps when the drawer switching execution component 82 switches to the push-unlock state in step 2.1 include: the AGV medicine delivery trolley 6 pushes the rotating roller 811 to slide along the positioning rotating rod 813; the rotating pressure plate 816 fixedly connected to the rotating roller 811 pushes the relay plate 823; the relay plate 823 drives the sliding lever 822 to rotate around the central rotating rod 821; the sliding lever 822 moves the spring pin 829 to disengage it from the pin slot block 824; the guide rail frame 826 resets under the action of the tension spring 827; and the guide rail frame 826 retracts.

[0084] Preferably, in step 2.1, when the AGV medicine delivery trolley 6 pushes the rotating roller 811, the drawer switching active component 81 can switch back and forth between the push belt guide frame 826 and the relay plate 823. The rotating roller 811 can slide along the positioning rotating rod 813 under the push of the AGV medicine delivery trolley 6. When the AGV medicine delivery trolley 6 stops pushing, the rotating roller 811 can slide and reset and rotate 180 degrees under the action of the compression spring 814 and the limiting elastic pressure block 812.

[0085] Preferably, the specific steps of step 2.2 include: while the AGV medicine delivery trolley 6 pushes the drawer switching active component 81, it drives the rotating plate 702 of the seedling turning device 7 to approach the positioning elastic pin 701. When the AGV medicine delivery trolley 6 pushes the drawer switching active component 81 to the maximum limit, the positioning elastic pin 701 enters the guide channel 705 through the guide groove 704 of the rotating plate 702.

[0086] Preferably, the specific steps of step 2.3 include: when the drawer switching actuator 82 switches from the push-lock state to the push-unlock state, the hollow telescopic mother plate 901 is no longer limited by the drawer switching actuator 82, and the telescopic daughter plate 902 slides out from the hollow telescopic mother plate 901 under the action of gravity. One end of the telescopic daughter plate 902 slides along the guide rail 904 under the action of the guide block 903 until the telescopic daughter plate 902 contacts the limiting rod 905. At this time, the vaccine poured out by the vaccine pouring device 7 enters the lower electric drawer 5 of the two alternating vaccine receiving electric drawers 5 through the vaccine guide device 9.

[0087] When the drawer switching actuator 82 switches from the push-unlock state to the push-lock state, the hollow telescopic mother plate 901 is pushed by the drawer switching actuator 82, and the hollow telescopic mother plate 901 rotates. The hollow telescopic mother plate 901 drives the telescopic daughter plate 902 to rotate. The telescopic daughter plate 902 rotates under the limit of the guide block 903 and the guide rail 904 and slides into the hollow telescopic mother plate 901 until the drawer switching actuator 82 reaches the maximum limit. At this time, the hollow telescopic mother plate 901 and the hollow telescopic daughter plate 902 stop moving. At this time, the vaccine poured out by the vaccine pouring device 7 enters the upper electric drawer 5 of the two alternating vaccine receiving electric drawers 5 through the vaccine guide device 9.

[0088] Preferably, step 3 includes the following steps: the AGV medicine delivery trolley 6 moves away from the drawer frame 4, thereby causing the vaccine tilting device 7 installed on the AGV medicine delivery trolley 6 to move away from the drawer frame 4. During the process of the vaccine tilting box 703 moving away from the drawer frame 4, the positioning elastic pin 701 pressed into the guide channel 705 of the rotating plate 702 plays a limiting role on the rotating plate 702, causing the rotating plate 702 to rotate. The rotating plate 702 drives the vaccine tilting box 703 to rotate. The vaccine in the vaccine tilting box 703 falls into the vaccine guiding device 9 under the action of gravity. When the AGV medicine delivery trolley 6 moves away until the rotating rod is no longer limited by the positioning elastic pin 701, the rotating plate 702 and the vaccine tilting box 703 are reset under the action of the first self-rebound rotating shaft.

[0089] Preferred, such as Figure 6 , Figure 7 and Figure 8 As shown, the drawer switching device 8 in step 2.1 includes a drawer switching active component 81 and a drawer switching execution component 82; the drawer switching active component 81, under the push of the AGV medicine delivery trolley 6, can make the drawer switching execution component 82 be in a push-lock state or a push-unlock state.

[0090] Preferred, such as Figure 6 , Figure 7 and Figure 8 As shown, the drawer switching active component 81 includes a rotating roller 811, a limiting elastic block 812, a positioning rotating rod 813, a pressure spring 814, a first fixing plate 815, and a rotating pressure plate 816. One end of the positioning rotating rod 813 is fixed to one side of the middle portion of the first fixing plate 815. The other end of the positioning rotating rod 813 is connected to the slidable and rotatable rotating pressure plate 816. The rotating pressure plate 816 is fixedly connected to the rotating roller 811. The pressure spring 814 is sleeved on the outer side of the positioning rotating rod 813. The limiting elastic block 812 is pressed into the groove of the rotating roller 811. The rotating roller 811 can slide along the positioning rotating rod 813 under the push of the AGV medicine delivery cart 6. When the AGV medicine delivery cart 6 stops pushing, the rotating roller 811 can slide back to its original position and rotate 180 degrees under the action of the pressure spring 814 and the limiting elastic block 812.

[0091] Both the rotating roller 811 and the rotating pressure plate 816 have circular grooves in their middle portions for sliding and rotating relative to the positioning rod 813.

[0092] One end of the compression spring 814 is fixed to the first fixed plate 815, and the other end of the compression spring 814 is mounted on the rotating pressure plate 816 through a bearing seat.

[0093] One end of the limiting elastic pressure block 812 is fixed to the drawer frame 4, and the other end of the limiting elastic pressure block 812 can be extended and pressed into the groove of the rotating roller 811.

[0094] Preferably, the surface of the rotating roller 811 is provided with two symmetrical straight grooves parallel to the center line of the positioning rotating rod 813. The head of one of the straight grooves is connected to the tail of the other straight groove through an arc-shaped groove on the surface of the rotating roller 811. When the AGV medicine delivery cart 6 pushes the rotating roller 811, the limiting elastic block 812 moves from the head to the tail of the straight groove and enters the arc-shaped groove. When the AGV medicine delivery cart 6 stops pushing the rotating roller 811, under the action of the compression spring 814 and the limiting elastic block 812, the limiting elastic block 812 moves from the head to the tail of the arc-shaped groove and enters the straight groove.

[0095] The head of the straight groove is slightly lower than the tail of the arc-shaped groove, and the tail of the straight groove is slightly higher than the head of the arc-shaped groove.

[0096] Preferred, such as Figure 6 , Figure 7 and Figure 8 As shown, the drawer switching actuator 82 includes a central rotating rod 821, a sliding lever 822, a relay plate 823, a pin-grooved block 824, a guide block 825, a guide rail frame 826, a tension spring 827, a second fixing plate 828, and spring pins 829. One end of the tension spring 827 is fixed to the middle of the second fixing plate 828, and the other end of the tension spring 827 is fixedly connected to the guide rail frame 826. The spring pins 829 are provided on both sides of the guide rail frame 826. When the guide rail bracket 826 moves, it can enter the groove of the pin-grooved block 824, and the guide block 825 is fixed on the pin-grooved block 824. The guide block 825 is slidably connected to the track of the guide rail bracket 826. The central rotating rod 821 has a self-rotating function, and the two sides of the central rotating rod 821 are fixed with sliding levers 822 that can be inserted into the gap between the pin-grooved block 824 and the guide rail bracket 826. The lower parts of the two sliding levers 822 are connected by a relay plate 823.

[0097] The second fixing plate 828 is fixedly connected to the drawer frame 4.

[0098] The two sides of the central rotating rod 821 are hinged to the drawer frame 4.

[0099] When the rotating pressure plate 816 pushes the guide rail frame 826 to insert the spring pin 829 into the pin slot 824, the rotating pressure plate 816 can abut against the vaccine guide device 9, so that when the vaccine is poured into the vaccine guide device 9, it will enter the electric drawer 5 in the middle.

[0100] When the rotating pressure plate 816 pushes the relay plate 823 to rotate the sliding lever 822, the sliding lever 822 can pull the spring pin 829 out of the pin slot block 824. At this time, the guide rail frame 826 is reset under the action of the tension spring 827 and no longer limits the vaccine guide device 9, so that when the vaccine is poured into the vaccine guide device 9, it will enter the electric drawer 5 at the bottom.

[0101] Preferred, such as Figure 5 As shown, the vaccine guiding device 9 includes a hollow telescopic mother plate 901, a telescopic daughter plate 902, a guide block 903, a guide rail 904, and a limiting rod 905. One end of the hollow telescopic mother plate 901 is hinged to the drawer frame 4 via a rod, and the telescopic daughter plate 902 is installed inside the hollow telescopic mother plate 901. The guide block 903 is hinged to both sides of one end of the telescopic daughter plate 902. The guide block 903 is slidably connected to the guide rail 904, and the limiting rod 905 is fixed between the guide rails 904.

[0102] The guide rail 904 is fixedly connected to the drawer frame 4.

[0103] When the telescopic subplate 902 contacts the limiting rod 905, the vaccine poured into the vaccine guide device 9 will enter the lowest electric drawer 5.

[0104] Preferred, such as Figure 4 As shown, the vaccine tilting device 7 includes a positioning elastic pin 701, a rotating plate 702, a tilting box 703, an inlet groove 704, and a guide channel 705. The upper end of the AGV medicine delivery cart 6 is hinged to one end of the rotating plate 702 via a first self-rebound rotating shaft, and the other end of the rotating plate 702 is fixedly connected to the tilting box 703. The rotating plate 702 has the inlet groove 704 and the guide channel 705. When the AGV medicine delivery cart 6 moves to a position where the drawer switching actuator 82 is in a push-locked or push-unlocked state, the positioning elastic pin 701 can enter the guide channel 705 through the inlet groove 704. When the AGV medicine delivery cart 6 completes the state switching of the drawer switching actuator 82 and drives away, the positioning elastic pin 701 limits the rotating plate 702 through the guide channel 705, and the rotating plate 702 rotates, thereby driving the tilting box 703 to tilt the vaccine toward the vaccine guide device 9.

[0105] One end of the positioning elastic pin 701 is fixed to the drawer frame 4, and the retractable pin body at the other end of the positioning elastic pin 701 is used to enter the guide groove 704 and the guide channel 705.
