[0048] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0049] For example, although the embodiments described below are introduced in conjunction with vaccine storage devices, the technical solutions of the present invention are also applicable to other types of storage devices, such as storage devices for storing biological samples and biological reagents. Such adjustments and changes to the application objects do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0050] It should be noted that in the description of this invention, terms such as "inner," "outer," "upper," "lower," "left," "right," "top," and "bottom," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0051] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set," "connect," and "install" should be interpreted broadly, for example, referring to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0052] Specifically, such as Figure 1 and Figure 2 As shown, the vaccine storage equipment of the present invention includes a cryopreservation cell 1 and a shelf 7, a robotic arm device, and a buffer conveying device installed in the cryopreservation cell 1.

[0053] The cryopreservation facility 1 has a first window 11 and a second window 12. A buffer conveyor is provided corresponding to the second window 12. The buffer conveyor is configured to receive and buffer vaccines from the second window 12 and to convey the received vaccines to a robotic arm device. The buffer conveyor is also configured to receive and buffer vaccines from the robotic arm device and to transfer the received vaccines to the second window 12. The robotic arm device is configured to transfer vaccines between the shelf 7, the first window 11, and the buffer conveyor.

[0054] For example, such as Figure 1 and Figure 2 As shown, the cryopreservation room 1 has a rectangular structure. The first window 11 and the second window 12 are both located near the left side of the cryopreservation room. The first window 11 is located to the right of the second window 12. A workbench is placed outside the cryopreservation room 1 near the first window 11 and the second window 12. An empty vaccine box 2 is placed on the workbench. The vaccine box 2 is used to hold vaccines. The vaccine box 2 can enter and exit the cryopreservation room 1 through the first window 11 and the second window 12. The shelf 7 is provided with multiple storage positions, and each storage position can hold one vaccine box 2.

[0055] When a large number of vaccines need to be stored, a reservation storage task order can be created in advance in the host computer. After confirmation, it will be automatically sent to the vaccine storage management system. According to the storage task order, the vaccine storage management system controls the robotic arm to place multiple empty vaccine boxes 2 on the buffer conveyor for buffering in advance.

[0056] During the vaccine warehousing process, the first window 11 and the second window 12 open simultaneously. First, the buffer conveyor transports the empty vaccine boxes 2 it has buffered to the second window 12. The staff takes out the empty vaccine boxes 2 from the second window 12, places the vaccine into the vaccine box 2, and then places the vaccine box 2 containing the vaccine from the first window 11 onto the robotic arm device. The robotic arm device then transports the vaccine box 2 to the corresponding storage position, which greatly improves the efficiency of vaccine warehousing.

[0057] Similarly, when a large number of vaccines need to be shipped out, a pre-arranged shipment task order can be created in the host computer. After confirmation, it will be automatically sent to the vaccine warehouse management system. The vaccine warehouse management system will control the robotic arm to place multiple vaccine boxes 2 containing vaccines onto the buffer conveyor for buffering according to the shipment task order.

[0058] During the vaccine outbound process, the first window 11 and the second window 12 open simultaneously. First, the buffer conveyor transports the vaccine box 2 containing the vaccine to the second window 12. The staff takes out the vaccine box 2 from the second window 12, then takes out the vaccine from the vaccine box 2, and then places the empty vaccine box 2 from the first window 11 onto the robotic arm device. The robotic arm device transports the empty vaccine box 2 to the corresponding storage position, which greatly improves the vaccine outbound efficiency.

[0059] It should be noted that when only a small number of vaccines need to be stored, for example, if only one vaccine crate 2 is needed to hold the vaccines, no prior appointment is required. When the vaccines are being stored, only the first window 11 needs to be opened, while the second window 12 remains closed. A robotic arm first picks up an empty vaccine crate 2 from the shelf 7 and transports it to the first window 11. After the staff puts all the vaccines into the vaccine crate 2, the robotic arm then transports the vaccine crate 2 to the storage location on the shelf 7. Similarly, when only a small number of vaccines need to be released, no prior appointment is required either. The release of vaccines can be completed solely by a robotic arm, without the need for a buffer conveyor system.

[0060] In addition, it should be noted that the vaccine storage device of the present invention is also equipped with an electric door for each of the first window 11 and the second window 12. The first window 11 and the second window 12 can be closed by the two electric doors respectively. In addition, a refrigeration device is also provided in the cryopreservation room 1. The refrigeration device can refrigerate the cryopreservation room 1 to keep the cryopreservation room 1 in a low temperature environment.

[0061] Preferably, such as Figure 2 and Figure 3 As shown, the robotic arm device of the present invention includes a temporary storage and conveying device 3 and a transfer device 4.

[0062] The temporary storage and conveying device 3 is configured to receive and temporarily store vaccines from the buffer conveying device. The temporary storage and conveying device 3 is also configured to receive and temporarily store vaccines from the transfer device 4 and transfer vaccines to the buffer conveying device. The transfer device 4 is configured to transfer vaccines between the shelf 7, the first window 11, and the temporary storage and conveying device 3.

[0063] By setting up a temporary storage and transmission device 3, work efficiency can be improved.

[0064] Specifically, when a large number of vaccines need to be shipped out, the transfer device 4 first transfers the vaccine crate 2 (containing vaccines) located on the shelf 7 to the temporary storage and conveying device 3 for temporary storage. After the buffer conveying device buffers the previous vaccine crate 2, the temporary storage and conveying device 3 then transmits the temporarily stored vaccine crate 2 to the buffer conveying device. The transfer device 4 can take another vaccine crate 2 containing vaccines from the shelf 7 without waiting for the buffer conveying device to perform the buffering work, thereby improving the efficiency of the buffering work.

[0065] Preferably, such as Figures 2 to 6 As shown, the transfer device 4 of the present invention includes a first horizontal track 41, a second horizontal track 42, a vertical track 43, a first drive mechanism, a second drive mechanism, a third drive mechanism, and a telescopic mechanism 47.

[0066] The first horizontal track 41 extends along the length of the shelf 7; the second horizontal track 42 is installed on the first horizontal track 41 and extends along the width of the shelf 7; the first drive mechanism is installed between the first horizontal track 41 and the second horizontal track 42 and can drive the second horizontal track 42 to move along the first horizontal track 41; the vertical track 43 is installed on the second horizontal track 42; the second drive mechanism is installed between the vertical track 43 and the second horizontal track 42 and can drive the vertical track 43 to move along the second horizontal track; the telescopic mechanism 47 is installed on the vertical track 43 and can pick up and put down vaccines; the third drive mechanism is installed between the vertical track 43 and the telescopic mechanism 47 and can drive the telescopic mechanism 47 to move up and down along the vertical track 43.

[0067] For example, there are two first horizontal rails 41, which are spaced apart along the width of the shelf 7. Both first horizontal rails 41 are installed on the top of the shelf 7. The second horizontal rail 42 is located between the two first horizontal rails 41. The top of the vertical rail 43 is installed on the second horizontal rail 42.

[0068] The first horizontal track 41 includes a first crossbeam 411 and a first horizontal guide rail 412 mounted on the first crossbeam 411. The second horizontal track 42 includes a second crossbeam 421 and a first guide plate 422 mounted on the second crossbeam 421. There are two first guide plates 422, which are respectively mounted at both ends of the second crossbeam 421. The first guide plate 422 can slide along the first horizontal guide rail 412. The first drive mechanism includes a first rack 443 mounted on the first crossbeam 411 and a first motor 441 and a first gear 442 mounted on the second crossbeam 421. The first rack 443 is arranged parallel to the first horizontal guide rail 412. The first gear 442 meshes with the first rack 443 for transmission. The first motor 441 (dual-axis motor) can drive the first gear 442 to rotate.

[0069] The second horizontal track 42 also includes a second horizontal guide rail 423 mounted on the second crossbeam 421. The vertical track 43 includes a vertical beam 431 and a second guide plate 432 mounted on the top of the vertical beam 431. The second guide plate 432 can slide along the second horizontal guide rail 423. The second drive mechanism includes a second rack 452 mounted on the second crossbeam 421 and a second motor 451 and a second gear (not shown in the figure) mounted on the second guide plate 432. The second rack 452 is arranged parallel to the second horizontal guide rail 423. The second gear meshes with the second rack 452 for transmission. The second motor 451 can drive the second gear to rotate.

[0070] The vertical track 43 also includes a vertical guide rail 433 mounted on the vertical beam 431. The telescopic mechanism 47 includes a third guide plate 470. The third drive mechanism includes a third rack 462 mounted on the vertical beam 431 and a third motor 461 and a third gear (not shown in the figure) mounted on the third guide plate 470. The third rack 462 is arranged parallel to the vertical guide rail 433. The third gear meshes with the third rack 462 for transmission. The third motor 461 can drive the third gear to rotate.

[0071] It should be noted that in practical applications, the above-mentioned guide rail and guide plate can be replaced with a structure in which the guide groove and guide block cooperate. In addition, the above-mentioned rack and gear can be replaced with a structure in which the lead screw and nut cooperate, etc. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention and should be limited to the protection scope of the present invention.

[0072] Preferably, such as Figures 4 to 12 As shown, the telescopic mechanism 47 of the present invention includes a fixed seat 471 mounted on a vertical rail 43, and a fourth drive mechanism, a first telescopic plate 473, a second telescopic plate 474, a first sprocket 475, a second sprocket 476, a first chain 477, and a second chain 478 mounted on the fixed seat 471.

[0073] The third drive mechanism can drive the fixed base 471 to move up and down along the vertical track 43; the fourth drive mechanism is connected to the first telescopic plate 473 and can drive the first telescopic plate 473 to move horizontally relative to the fixed base 471; the second telescopic plate 474 is mounted on the first telescopic plate 473 and can move horizontally relative to the first telescopic plate 473; the first sprocket 475 and the second sprocket 476 are both pivotally mounted on the first telescopic plate 473 and are spaced apart along the moving direction of the first telescopic plate 473.

[0074] One end of the first chain 477 is fixedly connected to one end of the fixed base 471, and the other end of the first chain 477 passes around the first sprocket 475 and is fixedly connected to one end of the second telescopic plate 474, so that when the first telescopic plate 473 moves to the right in the horizontal direction relative to the fixed base 471, it drives the second telescopic plate 474 to move to the right in the horizontal direction relative to the first telescopic plate 473; one end of the second chain 478 is fixedly connected to the other end of the fixed base 471, and the other end of the second chain 478 passes around the second sprocket 476 and is fixedly connected to the other end of the second telescopic plate 474, so that when the first telescopic plate 473 moves to the left in the horizontal direction relative to the fixed base 471, it drives the second telescopic plate 474 to move to the left in the horizontal direction relative to the first telescopic plate 473.

[0075] This configuration increases the telescopic stroke of the telescopic mechanism 47.

[0076] For example, the fixed seat 471 of the telescopic mechanism 47 is fixedly connected to or integrally set with the third guide plate 470 of the telescopic mechanism 47 described above. When the third motor 461 drives the third gear to move up and down along the third rack 462, the fixed seat 471 and the structure installed on the fixed seat 471 can be moved up and down through the third guide plate 470.

[0077] The fourth drive mechanism includes a fourth motor 4721 mounted on a fixed base 471, a fourth gear 4722 (not shown in the figure) fixedly connected to the output shaft of the fourth motor 4721, and a fourth rack 4723 mounted on the bottom of the first telescopic plate 473. The fourth rack 4723 meshes with the fourth gear 4722 and is arranged in a horizontal direction.

[0078] The first sprocket 475 is installed at the right end of the first telescopic plate 473, and the second sprocket 476 is installed at the left end of the first telescopic plate 473. The fixed base 471 is provided with a first fixing structure 4711 and a second fixing structure 4712. The first fixing structure 4711 is located at the left end of the fixed base 471, and the second fixing structure 4712 is located at the right end of the fixed base 471. The second telescopic plate 474 is provided with a first connecting structure 4741 and a second connecting structure 4742. The first connecting structure 4741 is located at the left end of the second telescopic plate 474, and the second connecting structure 4742 is located at the right end of the second telescopic plate 474.

[0079] One end of the first chain 477 is fixedly connected to the first fixing structure 4711, and the other end of the first chain 477 is fixedly connected to the first connecting structure 4741 after passing over the first sprocket 475. One end of the second chain 478 is fixedly connected to the second fixing structure 4712, and the other end of the second chain 478 is fixedly connected to the second connecting structure 4742 after passing over the second sprocket 476. The lengths of the first chain 477 and the second chain 478 are equal.

[0080] When the fourth drive mechanism drives the first telescopic plate 473 to move to the right relative to the fixed base 471, the first chain 477 pulls the second telescopic plate 474 to move to the right relative to the first telescopic plate 473. When the fourth drive mechanism drives the first telescopic plate 473 to move to the left relative to the fixed base 471, the second chain 478 pulls the second telescopic plate 474 to move to the left relative to the first telescopic plate 473.

[0081] The fixed base 471 is provided with a first guide wheel assembly 4713, the first telescopic plate 473 is provided with a first guide groove 4731 and a second guide groove 4732, and the second telescopic plate 474 is provided with a second guide wheel assembly 4743. The first guide wheel assembly 4713 cooperates with the first guide groove 4731 to guide the first telescopic plate 473 during its movement relative to the fixed base 471. The second guide wheel assembly 4743 cooperates with the second guide groove 4732 to guide the second telescopic plate 474 during its movement relative to the first telescopic plate 473.

[0082] Preferably, such as Figure 7 , Figure 8 and Figure 10 As shown, the telescopic mechanism 47 of the present invention also includes a limiting member installed on the fixed base 471, which can limit the vaccine located in the fixed base 471 to prevent the vaccine from falling out of the fixed base 471.

[0083] It should be noted that, in practical applications, those skilled in the art can set the limiting component as a limiting plate 479, a limiting block, or a limiting post, etc. Such adjustments and changes to the specific structural form of the limiting component do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0084] Preferably, such as Figure 7 , Figure 8 and Figure 10 As shown, the limiting member includes two limiting plates 479 arranged opposite each other in the horizontal direction. The ends of the limiting plates 479 have inclined guide portions 4791 so that the vaccine can smoothly enter between the two limiting plates 479.

[0085] For example, the width between the two limiting plates 479 is slightly larger than the width of the vaccine frame 2. Each limiting plate 479 has an inclined guide 4791 at both the left and right ends. In this way, the telescopic mechanism 47 can smoothly enter the vaccine frame 2 between the two limiting plates 479, whether it is taken from the left or the right side.

[0086] Preferably, such as Figure 13 and Figure 14 As shown, the temporary storage and transfer device 3 of the present invention includes a first fixed member 31 and a temporary storage and transfer mechanism 32 and a lifting mechanism 33 installed on the first fixed member 31.

[0087] The temporary storage and conveying mechanism 32 is configured to receive and temporarily store vaccines from the buffer conveying device, and to convey vaccines transferred from the transfer device 4 to the buffer conveying device. The lifting mechanism 33 is configured to rise relative to the temporary storage and conveying mechanism 32 and lift the vaccines located on the temporary storage and conveying mechanism 32 so that the transfer device 4 can extract the vaccines. The lifting mechanism 33 is also configured to receive vaccines from the transfer device 4 and place the vaccines on the temporary storage and conveying mechanism 32 during the process of descending relative to the temporary storage and conveying mechanism 32.

[0088] For example, the first fixed component 31 is a first fixed frame, and the temporary storage and conveying mechanism 32 includes a seventh drive mechanism and a horizontal conveyor belt 321 mounted on the first fixed frame. The seventh drive mechanism includes a seventh motor 322, a first transmission belt 323 and a first transmission shaft 324. One end of the first transmission shaft 324 is connected to the drive shaft of the seventh motor 322 through the first transmission belt 323. The horizontal conveyor belt 321 is connected to the first transmission shaft 324. There are two horizontal conveyor belts 321, which are spaced apart along the length of the first transmission shaft 324. The seventh motor 322 drives the first transmission shaft 324 to rotate through the first transmission belt 323. The first transmission shaft 324 drives the two horizontal conveyor belts 321 to move synchronously. The horizontal conveyor belts 321 can carry the vaccine frame 2.

[0089] The lifting mechanism 33 includes an eighth drive mechanism and a lifting plate 331 mounted on a first fixed frame. The eighth drive mechanism includes an eighth motor 332, a first gear transmission group 333, a first vertical lead screw 334, and a first nut 335 screwed to the first vertical lead screw 334. The output shaft of the eighth motor 332 (arranged vertically) is driven and connected to the first vertical lead screw 334 through the first gear transmission group 333. The lifting plate 331 is fixedly connected to the first nut 335 and is located between two horizontal conveyor belts 321. The top surface of the lifting plate 331 is provided with multiple upwardly protruding support structures 3311. The eighth motor 332 can drive the first vertical lead screw 334 to rotate through the first gear transmission group 333. As the first vertical lead screw 334 rotates, the first nut 335 drives the lifting plate 331 to move up and down along the first vertical lead screw 334.

[0090] When the telescopic mechanism 47 needs to retrieve the vaccine frame 2 from the temporary storage and conveying mechanism 32, the eighth motor 332 first drives the first vertical screw 334 to rotate through the first gear transmission group 333. The first nut 335 drives the lifting plate 331 to rise as the first vertical screw 334 rotates. The multiple support structures 3311 on the lifting plate 331 support the bottom of the vaccine frame 2, lifting the vaccine frame 2 from the horizontal conveyor belt 321. There is a gap between the vaccine frame 2 and the top surface of the lifting plate 331. The second telescopic plate 474 can extend into the gap and support the bottom of the vaccine frame 2. Then, the eighth motor 332 drives the first vertical screw 334 to rotate in the opposite direction through the first gear transmission group 333. The first nut 335 drives the lifting plate 331 to descend as the first vertical screw 334 rotates, causing the vaccine frame 2 to fall onto the second telescopic plate 474.

[0091] It should be noted that in practical applications, the temporary storage and conveying mechanism 32 can also be configured as a horizontal conveying cylinder. In addition, the lifting mechanism 33 can also be configured as a hydraulic lifting mechanism, etc. Such adjustments and changes to the specific structural forms of the temporary storage and conveying mechanism 32 and the lifting mechanism 33 do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0092] Preferably, such as Figure 1 , Figure 2 and Figure 15 As shown, the buffer conveying device of the present invention includes a buffer conveying mechanism 5 and a hoist 6.

[0093] The buffer conveying mechanism 5 is a plurality of such mechanisms, which are distributed at intervals along the vertical direction. At least one of the buffer conveying mechanisms 5 is set to correspond to the second window 12 so as to receive the vaccine from the second window 12 and to convey the vaccine to the second window 12. The buffer conveying mechanism 5 is configured to buffer the vaccine and to convey the vaccine to the elevator 6 and to receive the vaccine from the elevator 6. The elevator 6 is located at the end of the buffer conveying mechanism 5 and is configured to convey the vaccine between the multiple buffer conveying mechanisms 5 and between the buffer conveying mechanism 5 and the temporary storage and conveying device 3.

[0094] For example, such as Figure 15 As shown, there are 5 buffer conveyor mechanisms 5, and each buffer conveyor mechanism 5 can buffer 5 vaccine boxes 2. Counting from the bottom up, the right end of the second buffer conveyor mechanism 5 is set to the second window 12. The elevator 6 is located at the left end of the buffer conveyor mechanism 5. The buffer conveyor mechanism 5 is set as a horizontal conveyor belt structure.

[0095] When a large number of vaccines need to be shipped out, the transfer device 4 first transfers the vaccine frame 2 to the temporary storage and conveying device 3. The temporary storage and conveying device 3 then transfers the vaccine frame 2 to the elevator 6. The elevator 6 then transfers the vaccine frame 2 to the buffer conveying mechanism 5 for buffering. During the process of the vaccine frame 2 being transferred from the elevator 6 to the buffer conveying mechanism 5, the transfer device 4 transfers another vaccine frame 2 to the temporary storage and conveying device 3, which is highly efficient.

[0096] It should be noted that in practical applications, the buffer conveying mechanism 5 can also be configured as a horizontal conveyor tube structure.

[0097] Preferably, such as Figures 15 to 20 As shown, the hoist 6 of the present invention includes a second fixed member 61 and a fifth drive mechanism 62, a first lifting seat 63, a first conveying mechanism 64, a sixth drive mechanism 65, a second lifting seat 66 and a second conveying mechanism 67 mounted on the second fixed member 61.

[0098] The fifth drive mechanism 62 is connected to the first lifting seat 63 and can drive the first lifting seat 63 to move up and down in the vertical direction relative to the second fixed member 61; the first transmission mechanism 64, the sixth drive mechanism 65, the second lifting seat 66 and the second transmission mechanism 67 are all installed on the first lifting seat 63.

[0099] The first conveying mechanism 64 is configured to receive vaccines from and convey vaccines to the buffer conveying mechanism 5; the sixth driving mechanism 65 is connected to the second lifting seat 66 and is configured to drive the second lifting seat 66 to move vertically up and down relative to the first lifting seat 63; the conveying direction of the second conveying mechanism 67 is perpendicular to the conveying direction of the first conveying mechanism 64, the second conveying mechanism 67 is mounted on the second lifting seat 66, the second conveying mechanism 67 is configured to rise with the second lifting seat 66 to lift the vaccine located on the first conveying mechanism 64 and convey the vaccine to the temporary storage conveying device 3, the second conveying mechanism 67 is also able to receive vaccines from the temporary storage conveying device 3 and place the vaccine on the first conveying mechanism 64 during the process of the second lifting seat 66 descending.

[0100] For example, the second fixing member 61 is a second fixing frame, and the fifth driving mechanism 62 includes a fifth motor 621 mounted on the second fixing frame, a second gear transmission group 622, a second vertical lead screw 623, and a second nut 624 screwed to the second vertical lead screw 623. The output shaft of the fifth motor 621 (arranged in the vertical direction) is driven to the second vertical lead screw 623 through the second gear transmission group 622. The first lifting seat 63 is fixedly connected to the second nut 624. The fifth motor 621 can drive the second vertical lead screw 623 to rotate through the second gear transmission group 622. As the second vertical lead screw 623 rotates, the second nut 624 drives the first lifting seat 63 and the structure mounted on the first lifting seat 63 to move up and down along the second vertical lead screw 623.

[0101] The sixth drive mechanism 65 includes a sixth motor 651, a bevel gear transmission group 652, a second transmission belt 653, a third vertical lead screw 654, and a third nut (not shown) screwed to the third vertical lead screw 654. The output shaft of the sixth motor 651 (arranged in the horizontal direction) is driven to the third vertical lead screw 654 through the bevel gear transmission group 652 and the second transmission belt 653. The second lifting seat 66 is fixedly connected to the third nut. The sixth motor 651 can drive the third vertical lead screw 654 to rotate through the bevel gear transmission group 652 and the second transmission belt 653. As the third vertical lead screw 654 rotates, the third nut drives the second lifting seat 66 and the second transmission mechanism 67 mounted on the second lifting seat 66 to move up and down along the third vertical lead screw 654.

[0102] When a large number of vaccines need to be shipped out, the transfer device 4 first transfers the vaccine frames 2 to the temporary storage and conveying device 3. After the elevator 6 moves to the position opposite to the temporary storage and conveying device 3, the sixth motor 651 drives the third vertical screw 654 to rotate through the bevel gear transmission group 652 and the second transmission belt 653. As the third vertical screw 654 rotates, the third nut drives the second lifting seat 66 and the second conveying mechanism 67 installed on the second lifting seat 66 to move upward along the third vertical screw 654, so that the conveying surface of the second conveying mechanism 67 is higher than the conveying surface of the first conveying mechanism 64. The temporary storage and conveying device 3 then conveys the vaccine frames 2 to the second conveying mechanism 67.

[0103] Then, the sixth motor 651 drives the third vertical screw 654 to rotate in the opposite direction through the bevel gear transmission group 652 and the second transmission belt 653. As the third vertical screw 654 rotates in the opposite direction, the third nut drives the second lifting seat 66 and the second conveying mechanism 67 installed on the second lifting seat 66 to move downward along the third vertical screw 654. When the conveying surface of the second conveying mechanism 67 is lower than the conveying surface of the first conveying mechanism 64, the vaccine frame 2 located on the second conveying mechanism 67 falls exactly on the first conveying mechanism 64. Finally, the first conveying mechanism 64 conveys the vaccine frame 2 to the buffer conveying mechanism 5 for buffering.

[0104] It should be noted that the fifth drive mechanism 62 and the sixth drive mechanism 65 are not limited to the specific structural forms described above. For example, both the fifth drive mechanism 62 and the sixth drive mechanism 65 can be set as hydraulic drive mechanisms, or the screw and nut can be replaced with the rack and gear, etc. Such adjustments and changes to the specific structural forms of the fifth drive mechanism 62 and the sixth drive mechanism 65 do not deviate from the principles and scope of the present invention, and should be limited to the protection scope of the present invention.

[0105] Furthermore, it should be noted that in practical applications, the first conveying mechanism 64 can be configured as a conveying cylinder or a conveyor belt, and the second conveying mechanism 67 can be configured as a conveying cylinder or a conveyor belt, etc. Such adjustments and changes to the specific structural forms of the first conveying mechanism 64 and the second conveying mechanism 67 do not deviate from the principles and scope of the present invention, and should all be limited to the protection scope of the present invention.

[0106] Preferably, such as Figures 17 to 20 As shown, the first conveying mechanism 64 includes multiple conveying cylinders distributed in a horizontal direction, and the second conveying mechanism 67 includes multiple conveyor belts 671 distributed at intervals in a horizontal direction and located between corresponding two conveying cylinders.

[0107] For example, there are six conveyor cylinders, two conveyor belts 671, three conveyor cylinders between the two conveyor belts 671, one conveyor cylinder on the other side of one conveyor belt 671, and two conveyor cylinders on the other side of the other conveyor belt 671.

[0108] The second conveying mechanism 67 includes a ninth motor 672, a third transmission belt 673, and a second transmission shaft 674. The second transmission shaft 674 is connected to the output shaft of the ninth motor 672 via the third transmission belt 673. Two transmission belts 671 are respectively connected to both ends of the second transmission shaft 674. The ninth motor 672 drives the second transmission shaft 674 to rotate via the third transmission belt 673, and the second transmission shaft 674 drives the two transmission belts 671 to move synchronously.
