[0042] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0043] For the vaccine workstation, some vaccines are delivered in the form of a whole box, and each box of vaccines includes a plurality of vaccine boxes. Each vaccine box includes a plurality of vaccines. When using vaccines, a whole box is generally taken out, and the remaining vaccines are stored in a refrigerator after use. The vaccine workstation provided by the embodiments of the present disclosure mainly transfers and stores vaccines in the form of boxes. Unless otherwise specified, the vaccine in the following refers to a whole box of vaccines in a packaging box. The vaccine supplement refers to the operation of placing the boxed vaccine back into the vaccine workstation.

[0044] In combination Figures 1-11As shown, the embodiment of the present disclosure provides a mechanical hopper 310 for transferring vaccines, the mechanical hopper 310 comprising a base plate 311, a first side plate 312, a second side plate 314, and an unlocking mechanism, wherein the base plate 311 is arranged obliquely to form a sliding plane on the upper surface; the first side plate 312 is arranged on the sliding plane; the second side plate 314 is arranged on the sliding plane, and the second side plate 314 cooperates with the first side plate 312 and part of the sliding plane to define a transfer chute 301; the unlocking mechanism 320 is arranged at the seed receiving end of the transfer chute 301, and the unlocking mechanism 320 comprises a hook 321, which, after the base plate 311 is moved upward, holds the front end of the vaccine upward to make the vaccine disengage from the limiting part, and the upward contact plane of the hook 321 is smoothly connected with the sliding plane.

[0045] The mechanical hopper 310 provided by the embodiment of the present disclosure is used to be connected with the chute to transfer vaccines. Exemplarily, the vaccine workstation comprises a seed receiving chute 210, and the mechanical hopper 310 is connected with the seed receiving chute to transfer vaccines.

[0046] The mechanical hopper 310 comprises a base plate 311, a first side plate 312, and a second side plate 314, and the upper surface of the base plate 311 is arranged obliquely to form an oblique sliding plane. The first side plate 312 and the second side plate 314 extend along the sliding direction to provide limiting on the left and right sides during the sliding of the vaccine.

[0047] The mechanical hopper 310 further comprises an unlocking mechanism 320, which is used to make the vaccine disengage from the limiting part. Exemplarily, the end of the seed storage chute 110 is provided with a baffle, and the unlocking mechanism 320 is used to push the vaccine upward and beyond the baffle.

[0048] Specifically, the unlocking mechanism 320 comprises a hook 321, and the hook 321 has an upward contact plane. The hook 321 extends outward beyond the seed receiving end of the transfer chute 301, and when the seed receiving chute 210 is connected with the seed storage chute at the seed receiving end and the seed discharging end, the hook 321 can extend below the seed storage chute 110. The contact plane of the hook 321 is arranged obliquely. The contact plane of the hook 321 is smoothly connected with the sliding plane, which means that there is no step between the contact plane and the sliding plane.

[0049] For example, in the process of transferring a vaccine, the vaccine is placed in the receiving chute 210, and the front end is positioned by the baffle of the receiving chute 210. The mechanical bucket 310 moves towards the storage chute with the entry end lower than the exit end of the storage chute 110, and the hook 321 extends below the storage chute. The mechanical bucket 310 moves upwards, and the entry end of the transfer chute 301 is aligned with the exit end of the storage chute 110. During this process, the hook 321 moves upwards with the mechanical bucket 310, lifts the bottom of the vaccine, and makes the front end of the bottom of the vaccine exceed the baffle. The vaccine changes from being attached to the bottom of the receiving chute 210 to being attached to the plane of the hook 321. Since the baffle is no longer limited, the vaccine slides along the plane where the contact plane of the hook 321 is located under the action of gravity. Since the contact plane of the hook 321 is smoothly connected to the sliding plane of the transfer chute 301, the vaccine smoothly slides into the transfer chute 301 under the action of gravity.

[0050] The mechanical bucket 310 provided by the embodiments of the present disclosure is provided with an unlocking structure, so that the corresponding storage vaccine chute does not need to be provided with a structure for releasing the vaccine, and in the case of a large number of storage vaccine chutes, the equipment cost can be reduced. The vaccine is unlocked by the hook 321 lifting the vaccine upwards, which is simple in structure and stable in function. The contact plane of the hook 321 is smoothly connected to the sliding plane where the bottom plate of the receiving chute 210 is located, and the vaccine will not overturn due to the height difference during the unlocking process, thereby improving the reliability of transferring the vaccine.

[0051] Optionally, as one embodiment of the smooth connection between the contact plane and the sliding plane, the contact plane and the sliding plane are located on the same plane.

[0052] With such a setting form, the contact plane and the sliding plane have the same slope. This is conducive to setting the slope of the mechanical bucket 310 and fixing the hook 321.

[0053] Optionally, as another embodiment of the smooth connection between the contact plane and the sliding plane, the position where the contact plane and the sliding plane are connected is smoothly transitioned.

[0054] During the process of lifting the vaccine by the hook 321, the angle between the bottom of the vaccine and the horizontal plane decreases. The contact plane and the sliding plane are smoothly transitioned, and the sliding plane can be set to have a different slope from the contact plane, so that the vaccine can return to the same angle as in the storage chute after sliding into the transfer chute. With such a setting method, it is conducive to the connection between the transfer chute 301 and the subsequent storage chute 110 or other storage units.

[0055] Optionally, the unlocking mechanism 320 further comprises a roller, and the roller is arranged on the hook 321 and beyond the contact plane arranged on the hook 321.

[0056] During the process of lifting the vaccine upward by the hook 321, the angle between the bottom of the vaccine and the horizontal plane decreases, and the component of the gravity along the contact plane decreases. In addition, compared with the vaccine receiving chute 210, the contact area between the bottom of the vaccine and the contact plane also decreases. This may cause the vaccine to be difficult to overcome the static friction and slide to the transfer chute 301. The contact plane of the hook 321 is provided with a roller, so that the friction of the vaccine sliding downward is reduced. This can make the vaccine more easily slide from the vaccine storage chute 110 to the transfer chute 301.

[0057] Optionally, the roller is an idler.

[0058] An idler is a wheel that is not provided with a driving structure. The roller is an idler, which can reduce the cost increased due to the setting of the roller.

[0059] Optionally, the unlocking structure includes a driving motor, and the driving motor is used to drive the roller to rotate. Illustratively, the driving motor is connected to the roller through a gear, and the driving motor drives the roller to rotate when the driving motor rotates.

[0060] With such a setting form, the vaccine no longer slides downward completely by its own gravity. Even if some vaccines take special packaging and have relatively large friction, the mechanical bucket 310 can still smoothly transfer the vaccine from the vaccine receiving chute to the transfer chute 301.

[0061] Optionally, the roller is made of rubber or silicone.

[0062] Rubber or silicone material has relatively large friction, and is more likely to drive the vaccine to slide downward. In addition, the roller made of rubber or silicone material also plays a role in limiting the sliding speed of the vaccine. Illustratively, in some cases, the vaccine has relatively small friction and slides relatively fast. The roller can limit the sliding speed of the vaccine from the vaccine receiving chute 210 to the transfer chute 301, so that the vaccine can slide to the transfer chute 301 at a lower speed. With such a setting form, different specifications of vaccines can be given a certain initial sliding speed by the roller, so that the mechanical bucket 310 can smoothly transfer vaccines of different specifications.

[0063] Optionally, the unlocking mechanism 320 includes an unlocking driving device 322, and the unlocking driving device 322 is arranged on the base plate 311 and connected to the hook 321. The unlocking driving device 322 is used to drive the hook 321 to move along the sliding direction of the transfer chute 301.

[0064] When the vaccine is stored in the vaccine storage chute 210 and is lifted upward by the hook 321, the vaccine needs to change from a static state to a sliding state. The static friction is greater than the sliding friction, so the vaccine may be lifted by the hook 321 but not slide downward. The unlocking driving device 322 is arranged to move the vaccine a certain distance in the direction of the transfer chute 301 after the vaccine is lifted. After the vaccine has an initial speed, the vaccine is easy to overcome the static friction under the action of inertia, and thus smoothly slides into the transfer chute 301.

[0065] Optionally, the end of the transfer chute 301 is provided with a relief gap 211, and the hook 321 is accommodated in the relief gap 211 when the hook 321 moves inward.

[0066] When the vaccine is accommodated in the relief gap 211, the vaccine is mainly received by the transfer chute 301. The vaccine is easy to continue to slide along the transfer chute 301. The relief gap 211 of the transfer chute 301 can accommodate the hook 321 and avoid the front and rear movement of the hook 321. In addition, during the movement of the mechanical hopper 310, the hook 321 is accommodated in the relief gap 211, and the hook 321 is not easy to contact other parts of the vaccine workstation.

[0067] Optionally, the hook 321 has a plurality of tines, and the upper surface of the tines forms a contact plane.

[0068] When the vaccine is lifted by the hook 321, the downward side of the vaccine is in contact with the contact plane. The hook 321 includes a plurality of tines, which can make each position of the bottom of the vaccine in contact with the contact plane, thereby reducing or avoiding the situation that the vaccine falls from the hook 321.

[0069] Optionally, the end of the transfer chute 301 is provided with a plurality of relief gaps 211, and the plurality of relief gaps 211 correspond to the plurality of tines of the hook 321.

[0070] With such a setting form, after the plurality of tines of the hook 321 are accommodated in the plurality of relief gaps 211, the hook 321 can be spliced with the plurality of relief gaps 211 of the transfer chute 301 to form a relatively complete plane. The plurality of tines and the plurality of relief gaps 211 form a certain guiding effect for the downward sliding of the vaccine, which is conducive to the smooth sliding of the vaccine.

[0071] Optionally, the slope of the contact surface of the hook 321 is smaller than the slope of the sliding plane.

[0072] When the vaccine is lifted by the hook 321, the angle between the bottom of the vaccine and the horizontal plane decreases, and the contact surface of the hook 321 tends to be the same. The slope of the contact surface is smaller than the slope of the sliding plane, and the vaccine can return to the same or close to the slope as when it is located in the receiving chute 210 when it slides to the transfer chute 301. Since the vaccine slides downward by its own gravity in both the transfer chute 301 and the receiving chute 210, the slopes of the transfer chute 301 and the receiving chute 210 are close, which is beneficial to the smooth and controllable sliding of the vaccine.

[0073] Optionally, the mechanical hopper 310 further comprises a side plate driving device 323 arranged below the base plate 311 and connected to the first side plate 312 and the second side plate 314. The side plate driving device 323 can drive the first side plate 312 and the second side plate 314 to move towards each other or in the opposite direction to adjust the width of the transfer chute 301.

[0074] Different specifications of vaccines have different widths, and vaccines of different widths are suitable for being stored in receiving chutes 210 or storing chutes 110 of corresponding widths to arrange the vaccines in the expected direction. In order to adapt the transfer chute 301 to vaccines of different widths, the width of the transfer chute 301 is adjustable.

[0075] Specifically, the first side plate 312 and the second side plate 314 of the transfer chute 301 are movable. When the side plate driving device 323 drives the first side plate 312 and the second side plate 314 to move towards each other, the width of the transfer chute 301 decreases. When the side plate driving device 323 drives the first side plate 312 and the second side plate 314 to move in the opposite direction, the width of the transfer chute 301 increases. With such a setting, the transfer hopper can adapt to vaccines of different specifications. Different specifications of vaccines are constrained in the width direction in the transfer chute 301, and the vaccines are not easy to overturn, so the vaccines can be smoothly slid in the expected direction.

[0076] Optionally, the side plate driving device 323 comprises a side plate driving motor 324, a rotating shaft 325, a first base 326 and a second base 327. The side plate driving motor 324 is arranged below the base plate 311. The rotating shaft 325 is rotatably arranged below the base plate 311 and is drivingly connected to the side plate driving motor 324. The first base 326 is penetrated by the rotating shaft 325, and the first side plate 312 is connected to the first base 326 through the base plate 311. The second base 327 is penetrated by the rotating shaft 325, and the second side plate 314 is connected to the second base 327 through the base plate 311. The first base 326 and the second base 327 are both threadedly connected to the rotating shaft 325. The thread direction of the rotating shaft 325 and the first base 326 is opposite to that of the rotating shaft 325 and the second base 327. When the rotating shaft 325 rotates, the first base 326 and the second base 327 move towards each other or in the opposite direction.

[0077] The axial direction of the rotating shaft 325 is along the width direction of the transfer chute 301. The two ends or the middle of the rotating shaft 325 are fixed to the lower side of the base plate 311 through bearings. The part of the rotating shaft 325 close to the first end has a first direction thread, and the part of the rotating shaft 325 close to the second end has a second direction thread. The first direction is opposite to the second direction. The first base has a first internal thread matched with the first thread, and the second base has a second internal thread matched with the second thread. The first side plate 312 is connected to the first base, and the second side plate 314 is connected to the second base. The side plate driving motor 324 is connected to the rotating shaft 325. When the driving motor rotates, the rotating shaft 325 rotates. When the rotating shaft 325 rotates, the first base and the second base move along the axial direction of the rotating shaft 325. Since the first thread and the second thread are in opposite directions, the first base and the second base move in opposite directions along the width direction of the transfer chute 301. When the first base and the second base move in opposite directions, the first side plate 312 and the second side plate 314 move towards each other or move in opposite directions, thereby adjusting the width of the transfer chute 301.

[0078] With such a setting, the center line of the transfer chute 301 is always in the same position during the adjustment of the width of the transfer chute 301, which is beneficial for the mechanical hopper 310 to position the transfer chute 301 so as to accurately dock with the seedling receiving chute 210 or the seedling storing chute 110. In addition, by moving the two side plates through one rotating shaft 325, the number of driving structures is less, which is beneficial for reducing the weight of the mechanical hopper 310 and reducing the cost of the mechanical hopper 310.

[0079] Optionally, the first side plate 312 is connected to the first base 326 through a first connecting piece 328, and the first connecting piece 328 includes a vertical connecting part and a transversely extending part connected to each other, the bottom end of the vertical connecting part extends to the first base 326, and the end of the transversely extending part is connected to the outer side wall of the first side plate 312. Mirror image, the second side plate 314 is connected to the second base 327 through a second connecting piece 329, and the second connecting piece 329 includes a vertical connecting part and a transversely extending part connected to each other, the bottom end of the vertical connecting part extends to the second base 327, and the end of the transversely extending part is connected to the outer side wall of the second side plate 314.

[0080] In this case, the first side plate 312 is located closer to the center line of the transfer chute 301 than the first base 326. In order to avoid the movement of the first connecting piece 328, an avoidance slot is opened in the base plate 311 above the first base. In this way, the avoidance slot is located away from the center line of the transfer chute. Even if the transfer chute 301 is adjusted to a relatively wide width, the avoidance slot is not easy to be located on the sliding route of the vaccine.

[0081] Adopting such a setting mode, the vaccine sliding blockage caused by the avoidance groove can be reduced or avoided.

[0082] Optionally, the mechanical hopper 310 further comprises a release mechanism 330 arranged at the emergence end of the transfer chute 301. The release mechanism 330 comprises a release cylinder 331 arranged below the base plate 311, and a release baffle 332 connected to the release cylinder 331. The release baffle 332 is in a stop state after being moved upward, and is in a release state after being moved downward.

[0083] The release mechanism 330 of the mechanical hopper 310 comprises the release cylinder 331 of the release baffle 332. The release cylinder 331 drives the unloading baffle to open and close. The release baffle 332 moves up and down relative to the transfer chute 301, and is not easy to interfere with other components of the vaccine workstation.

[0084] Optionally, the first side plate 312 is configured with a first hollow groove 313 at the emergence end of the transfer chute 301, and the second side plate 314 is configured with a second hollow groove 315 at the emergence end of the transfer chute 301. The mechanical hopper 310 further comprises a sensor comprising a receiving end 341 and a transmitting end 342. The transmitting end 342 is located outside the first hollow groove 313, and the receiving end 341 is located outside the second hollow groove 315. The transmitting end 342, the first hollow groove 313, the second hollow groove 315 and the receiving end 341 are located on the same straight line.

[0085] When there is vaccine at the emergence section of the transfer chute 301, the vaccine is located between the first hollow groove 313 and the second hollow groove 315. The signal emitted by the transmitting end 342 is blocked, and the receiving end 341 cannot receive the signal. When there is no vaccine at the emergence end of the transfer chute 301, the signal emitted by the transmitting end 342 is received by the receiving end 341. Adopting such a setting mode, whether the vaccine is in motion to the position of the transfer chute 301 can be accurately determined. The receiving end 341 and the transmitting end 342 are respectively located outside the first side plate 312 and the second side plate 314, and will not affect the sliding of the vaccine.

[0086] Optionally, the receiving end 341 and the transmitting end 342 of the sensor are fixed to the base plate 311.

[0087] In this way, the transmitting end 342 and the receiving end 341 of the sensor will not interfere with the movement of the first side plate 312 and the second side plate 314 along the width direction of the transfer chute 301, and will not cause signal dislocation due to the movement of the first side plate 312 and the second side plate 314.

[0088] The embodiment of the present disclosure provides a vaccine transfer device, which comprises a vaccine receiving module 200 and the mechanical hopper 310, wherein the vaccine receiving module 200 comprises an inclined vaccine receiving chute 210, the vaccine receiving chute 210 is provided with a baffle at the outlet end, and the bottom of the vaccine receiving chute 210 is provided with an avoiding gap 211 allowing the vaccine to be lifted upwards and beyond the baffle; the hook 321 of the mechanical hopper 310 lifts the vaccine upwards through the gap 211 so that the vaccine slides to the transfer chute 301.

[0089] The vaccine receiving module 200 is used for temporarily storing the vaccine. The vaccine receiving module 200 comprises the vaccine receiving chute 210. The vaccine receiving chute 210 is provided with a baffle and a gap 211 at the outlet end, and the hook 321 moves upwards from the gap 211 to make the vaccine beyond the baffle.

[0090] The vaccine transfer device provided by the embodiment of the present disclosure comprises the mechanical hopper 310, and has the same technical effects as the mechanical hopper 310, which will not be described here.

[0091] Optionally, the hook 321 comprises a plurality of prongs, and the bottom of the vaccine receiving chute 210 is provided with a plurality of gaps corresponding to the plurality of prongs.

[0092] With the arrangement, the vaccine is supported at each position of the bottom during the transfer from the vaccine receiving chute 210 to the hook 321, and is not easy to fall off from the hook 321 because of better stability.

[0093] Optionally, the inward side of the baffle is provided with a damping member.

[0094] With the arrangement, the damping member can absorb the impact energy when the vaccine slides to the outlet end of the vaccine receiving module 200, reduce the noise of the vaccine movement, and reduce or avoid the vaccine from being ejected from the transfer chute 301. In addition, since the damping member is arranged, the baffle only needs to be arranged at a lower height to block the vaccine, which is beneficial to the hook 310 of the mechanical hopper 310 to lift the vaccine from the vaccine receiving chute 210.

[0095] Optionally, the damping member is a damping plate, and the damping plate is connected to the inward side of the baffle by means of an elastic material capable of being compressed and deformed.

[0096] When the vaccine slides to the bottom of the vaccine receiving chute 210, the impact kinetic energy is converted into the elastic potential energy of the elastic material. When the elastic material releases the elastic potential energy, the damping plate only moves slightly.

[0097] Optionally, the angle between the inward side of the damping plate and the bottom plate of the vaccine receiving chute 210 is less than 85°.

[0098] When the vaccine slides down, it first directly contacts the top end of the shock-absorbing plate, and then compresses the elastic material through the shock-absorbing plate. In this process, even if the shock-absorbing plate is slightly rotated, it can still maintain good contact with the front side of the vaccine. With such a setting form, the situation that the vaccine is pushed out of the vaccine receiving chute 210 due to deformation of the shock-absorbing plate is alleviated or avoided.

[0099] The vaccine workstation further includes the mechanical hopper 310 or the vaccine transfer device.

[0100] Optionally, the vaccine workstation includes a workstation body 10, a storage module 100, a vaccine receiving module 200, and a transfer module 300. The workstation body 10 has a low-temperature storage area 11 formed inside, and the workstation body 10 is provided with a vaccine supplementing opening 12 and a vaccine discharging opening 13. The storage module 100 is arranged in the low-temperature storage area 11 and includes a plurality of vaccine storage chutes 110. The vaccine receiving module 200 is arranged in the low-temperature storage area 11 and opposite to the vaccine supplementing opening 12, and the vaccine receiving module 200 is provided with a plurality of vaccine receiving chutes 210. The transfer module 300 is arranged in the low-temperature storage area 11 and includes a movable transfer chute 301, the vaccine inlet end of the transfer chute 301 is adapted to be connected to the vaccine receiving chute 210, and the vaccine outlet end is adapted to be connected to the vaccine storage chute 110.

[0101] In the embodiments of the present disclosure, the workstation body 10 of the vaccine workstation has a low-temperature storage environment formed inside. Exemplarily, the workstation body 10 can be a cold storage with a large capacity and good temperature uniformity. Exemplarily, the workstation body 10 can be a heat preservation box with a small volume and a flexible setting position.

[0102] The vaccine workstation further includes the storage module 100, and the storage module 100 includes the vaccine storage chutes 110. The chute in the embodiments of the present disclosure refers to a storage unit with an inclined slope and two side limiting baffles, and a storage material can spontaneously slide from one end to the other end to store single or single-row materials. The storage module 100 includes a plurality of vaccine storage chutes, and can store a plurality of different vaccines. In one use mode, only one box of vaccine is stored in each vaccine storage chute. In this way, the situation that the vaccines are stored in a first-in last-out manner can be avoided. In another use mode, a plurality of vaccines of the same type or vaccines with the same packaging box size are stored in each vaccine storage chute. In this way, the number of vaccines that can be stored in the storage unit can be increased.

[0103] The workstation body 10 is provided with the vaccine supplementing opening 12. The opening size of the vaccine supplementing opening is smaller than the opening size of a conventional door body, and too much cold energy will not be leaked when the vaccine supplementing opening is opened.

[0104] The vaccine workstation further comprises a vaccine receiving module 200 which is connected to the vaccine supplementing opening. The vaccine receiving module 200 comprises a plurality of vaccine receiving chutes 210. The plurality of vaccine receiving chutes 210 can simultaneously store a plurality of vaccine boxes or a plurality of different vaccines. The staff performs vaccine sorting at the vaccine receiving window and stores the vaccines into the vaccine receiving chutes 210 at the same time. In this way, the efficiency of storing the vaccines into the vaccine workstation can be improved and the opening time of the vaccine supplementing opening can be reduced.

[0105] The vaccine workstation further comprises a transfer module 300 which comprises a movable transfer chute 301. The transfer chute 301 moves to a position which is connected to the vaccine receiving chute 210 and the vaccines in the vaccine receiving chute 210 enter the transfer chute 301. The transfer chute 301 moves to a position which is connected to the vaccine storing chute 110 and the vaccines in the transfer chute 301 slide into the vaccine storing chute 110. The staff can place a plurality of vaccine boxes in a plurality of vaccine receiving chutes 210 at one time and the transfer module 300 transfers the vaccines to the storing module 100 one by one.

[0106] Using the vaccine workstation provided by the embodiments of the present disclosure, the sorting of the vaccines is completed by the staff outside the low-temperature storage area 11, which improves the working environment of the staff. The vaccine receiving module 200 is provided with a plurality of vaccine receiving chutes 210, which improves the speed of sorting and placing the vaccines into the low-temperature storage space and reduces the opening time of the vaccine supplementing opening. The vaccines sequentially pass through the vaccine receiving chute 210, the transfer chute 301 and the vaccine storing chute when entering the storing module 100. The vaccines slide in the plurality of chutes under the action of their own gravity and the moving speed is relatively fast, which improves the efficiency of storing the vaccines. In addition, the vaccines are transferred through a plurality of chutes and the transfer module 300 needs to move a relatively short distance and occupies a relatively small space.

[0107] Optionally, the vaccine receiving module 200 is connected to the top end of the vaccine supplementing opening 12 at the vaccine entering end of the uppermost vaccine receiving chute 210. The vaccine receiving module 200 is connected to the bottom end of the vaccine supplementing opening 12 at the vaccine entering end of the lowermost vaccine receiving chute 210.

[0108] The vaccine receiving module 200 comprises a plurality of vaccine receiving chutes 210. The plurality of vaccine receiving chutes 210 are divided into a plurality of rows from top to bottom and each row comprises a vaccine receiving chute 210. In the view of the vaccine supplementing opening, the vaccine receiving module 200 presents a plurality of compartments. The cold air in the cold storage is located in the lower space under the action of the cold-heat density difference and is not easy to overcome the action of gravity and escape to the outside of the low-temperature storage space against the transfer chute. In this way, the amount of cold air leakage during the supplementing of the vaccines can be reduced.

[0109] The seedling receiving module 200 is connected to the top end of the seedling receiving chute 210 in the uppermost row and the bottom end of the seedling receiving chute 210 in the lowermost row. In this way, on the one hand, the utilization efficiency of the seedling receiving chute 210 can be improved, and more seedling receiving chutes 210 can be arranged in the seedling receiving module 200. On the other hand, the seedling receiving chute 210 can rely on its own slope to achieve a sealing effect on the seedling receiving chute 210, thereby reducing the cold storage space leakage during the seedling receiving process.

[0110] Optionally, the storage module 100 is arranged above the seedling receiving chute 210 in the uppermost row, and the transfer chute 301 can move in the vertical direction and the horizontal direction to connect the seedling receiving end of any seedling receiving chute and the seedling storage end of any seedling storage chute 110.

[0111] The seedling receiving chute 210 is arranged above the seedling receiving chute 210 in the uppermost row, and the seedling receiving chute 210 in the lowermost row is arranged below the seedling receiving chute 210 in the lowermost row. In this way, on the one hand, the utilization efficiency of the seedling receiving chute 210 can be improved, and more seedling receiving chutes 210 can be arranged in the seedling receiving module 200. On the other hand, the seedling receiving chute 210 can rely on its own slope to achieve a sealing effect on the seedling receiving chute 210, thereby reducing the cold storage space leakage during the seedling receiving process.

[0112] In this way, the number of vaccines stored in the vaccine workstation can be increased, and the efficiency of receiving vaccines from the outside and positioning the vaccines can be improved.

[0113] Optionally, the transfer module 300 further comprises a horizontal fixing frame 350, a horizontal driving mechanism 360, a vertical moving frame 370, and a vertical driving mechanism 380. The horizontal fixing frame 350 is arranged in the low-temperature storage area 11. The vertical moving frame 370 is slidably arranged in the horizontal fixing frame 350. The mechanical bucket 310 is slidably arranged in the vertical moving frame 370. The horizontal driving mechanism 360 is used to drive the vertical moving frame 370 to slide horizontally along the horizontal fixing frame 350. The vertical driving mechanism 380 is used to drive the mechanical bucket 310 to slide up and down along the vertical moving frame 370.

[0114] To realize the movement of the transfer chute 301 in the vertical direction and the horizontal direction, the transfer module 300 comprises a horizontal fixed frame 350 and a vertical moving frame. The horizontal fixed frame 350 comprises a horizontal moving track, and the vertical moving frame is slidingly arranged on the horizontal moving track. The vertical moving frame 370 comprises a vertical moving track, and the transfer chute 301 is slidingly arranged on the vertical moving track. The transfer module 300 comprises a horizontal driving mechanism 360 and a vertical driving mechanism 380. The horizontal driving mechanism 360 is used to drive the vertical moving frame 370 to slide along the horizontal moving track, so that the transfer chute 301 moves in the horizontal direction with the vertical moving frame 370. The vertical driving mechanism 380 is used to drive the transfer chute 301 to slide along the vertical moving track, so that the transfer chute 301 moves in the vertical direction. When the vaccine is taken from the seedling receiving chute 210, the horizontal moving mechanism and the vertical moving mechanism act together to move the seedling receiving chute 210 to the position of abutting with the seedling receiving chute 210. After the vaccine enters the transfer chute 301, the horizontal moving mechanism and the vertical moving mechanism act together to move the seedling receiving chute 210 to the position of abutting with the seedling storage chute 110.

[0115] With such a setting mode, the seedling receiving chute 210 can conveniently move in the two-dimensional plane formed by the plurality of seedling receiving chutes 210 at the seedling outlet end or in the two-dimensional plane formed by the plurality of seedling storage chutes 110 at the seedling inlet end.

[0116] Optionally, the horizontal fixed frame 350 is fixed to the top wall of the workstation body 10.

[0117] With such a setting mode, the horizontal moving frame is not easy to interfere with the seedling receiving module 200 or the storage module 100, and it is convenient for the staff to enter the low-temperature storage area 11 to operate the vaccine or maintain each functional module. The top wall of the workstation body 10 can provide a plurality of fixing positions for the horizontal fixed frame 350, so as to improve the fixing effect of the horizontal fixed frame 350 and the vertical moving frame 370 connected to the horizontal fixed frame 350.

[0118] Optionally, the plurality of seedling receiving chutes 210 comprise a plurality of different widths to adapt to different specifications of vaccines, and the plurality of seedling storage chutes 110 comprise a plurality of different widths to adapt to different specifications of vaccines; the mechanical hopper 310 comprises a base plate 311, a first side plate 312 and a second side plate 314, wherein the base plate 311 forms the transfer chute 301 at the upper side; the first side plate 312 serves as one side wall of the transfer chute 301; the second side plate 314 serves as another side wall of the transfer chute 301; the first side plate 312 and the second side plate 314 are relatively movable to adjust the width of the transfer chute 301.

[0119] The plurality of receiving chutes 210 includes different widths, which means that the plurality of receiving chutes 210 has at least two and more than two widths. The receiving chutes 210 of different widths can be adapted to different specifications of vaccines. With such a setting, vaccines of different specifications can be placed in the receiving chutes 210 adapted thereto, avoiding the situation that vaccines are turned over or slide unsmoothly in the receiving chutes 210.

[0120] The plurality of receiving chutes 210 includes different widths, which means that the plurality of receiving chutes 210 has at least two and more than two widths. The receiving chutes 210 of different widths can be adapted to different specifications of vaccines. With such a setting, vaccines of different specifications can be placed in the receiving chutes 210 adapted thereto, avoiding the situation that vaccines are turned over or slide unsmoothly in the receiving chutes 210.

[0121] If the transfer module 300 is provided with a plurality of transfer chutes 301 of different widths, the transfer chutes 301 are too large in volume and inconvenient to move. The transfer chutes 301 are provided in a form of adjustable width. Specifically, the transfer chutes 301 include a base plate 311 and two side plates movable relative to each other. When transferring a wider vaccine, the first side plate 312 and the second side plate 314 move in opposite directions to increase the width of the transfer chute 301. When transferring a narrower vaccine, the first side plate 312 and the second side plate 314 move towards each other to decrease the width of the transfer chute 301.

[0122] With such a setting, the vaccine workstation can provide the receiving chutes 210, the transfer chutes 301 and the storage chutes 110 adapted to vaccines of a plurality of different specifications, improving the reliability of the vaccine workstation when transferring and storing vaccines.

[0123] Optionally, the vaccine workstation further includes a heating device 410, which is arranged along the circumference of the vaccine supplementing opening 12.

[0124] When the vaccine supplementing opening is opened, condensation may occur near the vaccine supplementing opening and the vaccine receiving end of the receiving chute 210 due to the temperature difference between the inside and outside of the low-temperature storage space. The condensation can change the friction of the receiving chute 210, affecting the receiving of vaccines by the receiving chute 210. The condensation can also soak the packaging box of the vaccine. In addition, the staff working near the vaccine supplementing opening can also feel uncomfortable due to the low temperature. By arranging the heating device 410 near the vaccine supplementing opening, the temperature near the vaccine supplementing opening can be increased. On the one hand, the working environment of the staff is improved, and on the other hand, the condensation near the vaccine supplementing opening and the receiving module 200 is reduced, so that the vaccine can slide down the receiving chute 210 more smoothly and will not be soaked by the condensation.

[0125] Optionally, the vaccine workstation further includes a control box 630, which is arranged outside the low-temperature storage area 11 and near the vaccine supplementing opening.

[0126] The control box 630 is arranged near the replenishment port and outside the low-temperature storage area 11, so that the staff can intervene in time when the transfer module 300 works abnormally, and press the emergency stop button or take over the subsequent operation of the transfer module 300.

[0127] Optionally, the vaccine workstation further comprises a fluent shelf 420, which is arranged in the low-temperature storage area and avoids the vaccine receiving module 200, the transfer module 300 and the storage module 100, and is suitable for storing whole-box vaccines.

[0128] Some vaccines are delivered in whole-box, and the whole-box vaccines can be stored in the fluent shelf 420. The fluent shelf 420 is arranged in a position avoiding the vaccine receiving module 200, the transfer module 300 and the storage module 100, and does not affect the transportation of the vaccines by the transfer module 300 when the vaccines are stored through the replenishment port.

[0129] As an optional implementation, the workstation body 10 is provided with a refrigeration door, and the staff can open the refrigeration door to manually supplement or take out the whole-box vaccines from the fluent shelf 420.

[0130] Optionally, the vaccine receiving module 200 further comprises a whole-box chute, and the vaccine outlet end of the transfer module 300 is further suitable for being connected with the vaccine inlet end of the fluent shelf 420.

[0131] With such an arrangement, the whole-box vaccines can also be supplemented into the fluent shelf 420 of the low-temperature storage space from outside the vaccine workstation, further facilitating the use of the user.

[0132] Optionally, the vaccine workstation further comprises a vaccine outlet module 500, which is connected with the vaccine outlet end of the storage chute 110, and is used to transfer the vaccines stored in the storage chute to the vaccine outlet port 13.

[0133] The vaccine outlet module 500 comprises a storage chute, the vaccine inlet end of the storage chute is suitable for being connected with the vaccine outlet end of the storage chute 110, and the vaccine outlet end of the vaccine outlet module 500 is suitable for being connected with the vaccine outlet port 13.

[0134] With such an arrangement, the vaccines of the vaccine workstation can be automatically discharged through the vaccine outlet module 500, which facilitates the use of the user. The vaccine outlet module 500 is arranged in the storage chute, which improves the speed of transferring the vaccines by the vaccine outlet module 500, reduces the use of space compared with the mode of the conveying belt, and reduces the cost of the vaccine workstation compared with the mode of arranging a mechanical hand.

[0135] Optionally, the vaccine workstation further comprises an operation table 600, a code scanning device 610 and a control device, wherein the operation table 600 is arranged outside the low-temperature storage area 11 corresponding to the vaccine supplementing opening 12; the code scanning device 610 is arranged on the operation table 600; and the control device is configured to allocate the vaccine with the vaccine receiving chute 210 and the vaccine storage chute according to the information of the code scanning device 610.

[0136] The operation table 600 is arranged to facilitate the staff to count and sort the vaccines before the vaccines are delivered. The code scanning device 610 is arranged to provide a hardware basis for the full automation of the vaccine workstation. Taking one use scenario as an example, after the vaccine is scanned at the operation table 600, the control device allocates the vaccine with the corresponding vaccine receiving chute 210 and vaccine storage chute 110, and controls the transfer chute 301 to adjust to the appropriate width. The user puts the vaccine into the corresponding vaccine receiving chute 210 according to the prompt of the control device. The vaccine slides to the vaccine delivery end of the vaccine receiving chute 210 under the action of gravity. The control device sends an instruction to the transfer module 300, and the horizontal driving device and the vertical driving device act to make the transfer chute 301 dock with the vaccine receiving chute 210. The unlocking structure of the transfer module 300 acts to make the vaccine in the vaccine receiving chute 210 slide to the transfer chute 301. The vaccine slides to the vaccine delivery end in the transfer chute 301. The horizontal driving device and the vertical driving device act to make the vaccine delivery end of the transfer chute 301 dock with the vaccine delivery end of the vaccine storage chute 110. The release mechanism 330 acts, and the vaccine slides into the vaccine storage chute 110. It should be noted that the user can put the vaccine into the corresponding vaccine receiving chute 210 after scanning the code, without waiting for the transfer module 300 to complete the transfer action. After the transfer module 300 transfers one box of vaccine, it automatically transfers the next box of vaccine.

[0137] With such a setting mode, the user is further facilitated to use, and the automation degree of the vaccine workstation is improved, and the efficiency of storing the vaccine is improved.

[0138] Optionally, the plurality of vaccine receiving chutes 210 are each provided with an indicator light; and the control device is further configured to control the indicator light of the vaccine receiving chute 210 corresponding to the vaccine to light up after the vaccine is scanned.

[0139] After the staff scans the vaccine, the control device allocates the vaccine with the vaccine receiving chute 210, and controls the indicator light of the vaccine receiving chute 210 to light up. According to the indication of the indicator light, the staff can accurately and quickly identify the allocated vaccine receiving chute 210, thereby improving the efficiency of the staff to sort the vaccine.
