[0034] The cryotube gripping mechanism is the mechanism in the biological sample library responsible for gripping and transferring the cryotubes in the target cryobox and the empty cryobox. It undertakes the work of picking and transferring. The traditional tube picking and gripping device picks a cryotube in the target cryobox, then moves it to the top of the empty cryobox and places the picked cryotube into the empty cryobox, and then returns to the top of the target cryobox to continue picking the next cryotube.

[0035] The freezing tube clamping device in the related art has the problem of low clamping efficiency when clamping a large number of freezing tubes.

[0036] Please refer to Figure 1-Figure 4 This embodiment provides a storage type cryotube clamping device 100. The storage type cryotube clamping device 100 can effectively improve the above-mentioned technical problems, improve the clamping efficiency of cryotubes, and improve work efficiency.

[0037] Please refer to Figure 1-Figure 4 The storage-type cryopreservation tube clamping device 100 includes a driving member 10, a moving member 20, a plurality of storage members 30 and a clamping member 40. The moving member 20 is connected to the driving member 10. The moving member 20 has a storage station and a waiting station. The plurality of storage members 30 are sequentially arranged at the storage station and the waiting station. Each storage member 30 is provided with a plurality of storage bins, which are used to place cryopreservation tubes. The clamping member 40 is connected to the driving member 10. The clamping member 40 is used to clamp a plurality of cryopreservation tubes in sequence under the drive of the driving member 10 and move the cryopreservation tubes to the storage station. When all the storage bins of the storage member 30 at the storage station are full of cryopreservation tubes, the moving member 20 moves to move the storage member 30 at the waiting station to the storage station to continue the storage work.

[0038] Specifically, in the prior art, a clamping device generally first picks a cryotube from a target cryobox, then moves it to an empty cryobox and places the picked cryotube into the empty cryobox, then returns to the target cryobox to continue picking the next cryotube. When the number of cryotubes to be clamped is large, this process is time-consuming and labor-intensive, and the clamping efficiency is low. To address this technical problem, the storage-type cryotube clamping device 100 provided in this embodiment is configured such that, during use, a driving member 10 drives a clamping member 40 to sequentially move to a target cryobox to clamp a cryotube. The clamping member 40 then moves the cryotube to a storage member 30 with the cryotube, placing the cryotube in a storage bin. When the storage member 30 at the storage station is filled with cryotubes, the moving member 20 moves, moving the fully loaded storage member 30 away from the storage station and simultaneously moving the storage member 30 at the waiting station to the storage station to continue loading cryotubes. The storage type cryotube clamping device 100 can clamp multiple cryotubes at one time through the cooperation between the moving part 20, the clamping part 40 and the multiple storage parts 30, thereby improving the clamping efficiency of the cryotubes and improving work efficiency.

The chain 233 is engaged with the driving sprocket 231 and the driven sprocket 232 at the same time. Both ends of the guide link 234 are connected to the guide shaft 25, and the storage part 30 is connected to the chain 233.

[0046] Specifically, the driving sprocket 231 rotates and drives the chain 233 meshed therewith to move. Driven by the chain 233 , the driven sprocket 232 also rotates synchronously with the driving sprocket 231 , thereby driving the storage element 30 to move.

[0050] In addition, the transmission member 21 includes a main transmission shaft 211, a slave transmission shaft 212, a connecting shaft 213, a main synchronous belt 214 and a slave synchronous belt 215.

[0051] Specifically, the main transmission shaft 211 is connected to the output shaft of the drive motor 22. The drive motor 22 drives the main transmission shaft 211 to rotate, so that the main transmission shaft 211 drives the main synchronous belt 214 to move. The connecting shaft 213 is driven by the main synchronous belt 214 to rotate through the slave synchronous belt 215, thereby achieving the purpose of driving the two active sprockets 231 to rotate at the same time.

[0052] In this embodiment, the storage component 30 includes a shell 31, an elastic component 32 and a storage plate 33. The storage plate 33 is arranged inside the shell 31, the elastic component 32 is arranged between the shell 31 and the storage plate 33, the shell 31 is connected to the fixed head 236, and the storage bin is arranged on the storage plate 33.

[0055] It should also be explained that the driving member 10 includes a clamping motor 11, a screw 12 and a slide rail 13. The clamping motor 11 is connected to the screw 12, the clamping member 40 is threadedly connected to the screw 12, and the clamping member 40 is slidably connected to the slide rail 13.

[0056] Furthermore, the clamping member 40 includes an electric chuck 41 and a fixing plate 42 . The fixing plate 42 is connected to the electric chuck 41 . The fixing plate 42 is threadedly connected to the lead screw 12 , and the fixing plate 42 is slidably connected to the slide rail 13 .

[0058] Specifically, the fixing plate 42 includes an extension plate and a connecting plate, the extension plate and the connecting plate are connected, the extension plate is slidably connected to the slide rail 13, and the extension plate is connected to the connecting block, and the connecting plate is connected to the electric chuck 41 away from the edge of the extension plate.

[0059] In this embodiment, the electric chuck 41 and the connecting plate are arranged vertically.

[0060] During operation, in the initial state, one of the two storage components 30 is in the storage station and the other is in the waiting station, and the first storage bin on the storage component 30 in the storage station is facing the electric clamp. The entire storage-type cryogenic tube clamping device 100 is moved to the top of the cryogenic tube to be clamped through the moving module, and then the clamping motor 11 drives the lead screw 12 to rotate forward and then drives the fixed plate 42 to drive the electric clamp to move downward to clamp the cryogenic tube below, and then the clamping motor 11 is reversed, and the electric clamp moves upward with the cryogenic tube until the cryogenic tube on the electric clamp is inserted into the first storage bin on the storage component 30 below, the electric clamp begins to loosen the cryogenic tube, and the clamping motor 11 continues to rotate forward so that the electric gripper moves downward to grab the next cryotube. At the same time, the drive motor 22 starts to rotate, driving the rotating part 23 to rotate through the transmission part 21, and then driving the storage parts 30 on the two rotating parts 23 to move. When the storage part 30 at the waiting position moves to the storage position and the first storage bin on the storage part 30 is facing the electric gripper, the drive motor 22 stops working, and then the electric gripper continues to move upward with the cryotube, thereby circulating the operation. When the storage bins of the two storage parts 30 are full of cryotubes, the entire cryotube clamping device moves to the top of the empty cryobox, and the cryotubes in the two storage parts 30 are inserted into the empty cryobox in turn.

When all the storage bins of the storage member 30 located at the storage station are full of cryogenic tubes, the moving member 20 moves to move the storage member 30 located at the waiting station to the storage station to continue the storage work. When the storage type cryotube clamping device 100 is in use, the driving member 10 drives the clamping member 40 to move to the target cryobox in sequence to clamp the cryotube, and then the clamping member 40 moves with the cryotube to the storage member 30 to place the cryotube in the storage bin.
