[0002] In the biomedical field, sample cryopreservation equipment is used to store biological samples such as blood samples, vaccines, and bacterial / viral strains at low temperatures, keeping the samples in liquid nitrogen for long-term viability preservation. The equipment contains multiple sample boxes, each containing multiple test tubes; the sample to be stored is contained within one of these test tubes.

[0003] In current cryopreservation equipment, during the extraction of biological samples, a lifting well mechanism needs to be added above the storage device to lift the basket out of the storage device, and then the sample box inside the basket is exported through an external fixed shovel mechanism. This not only occupies a lot of space, but the fixed lifting well mechanism is also more convenient. For larger storage refrigerators, it is inconvenient to extract the basket, which reduces work efficiency. Therefore, there is an urgent need for a sample storage and retrieval system.

[0110] It should be noted that the push rod drive mechanism 5104 rotates the push rod gear, which meshes with the push rod spur plate 5102, thereby driving the push rod spur plate 5102 to move. The push rod spur plate 5102 slides along the push rod spur plate support shaft 5103, which drives the push rod 5101 forward. The push rod 5101 pushes the plate frame out of the basket, causing the plate frame to fall onto the shovel plate 5201, which also facilitates the rotation gripping component 4 to grip or pick up the pipe.

[0111] It should be noted that when the basket is inside the support housing 3201, the push rod 5101 can scoop up the rack through the storage channel; the push block 5203 can also be stored in the rack through the storage channel.

[0115] Preferably, the drive lifting mechanism 602 can drive the telescopic rod 603 to lift and lower, and the telescopic rod drives the support rod 604 to lift and lower. The support rod 604 is provided with hook parts 605 on both sides. The hook parts 605 can hook the heat insulation cover on the upper surface of the storage compartment 2, and the heat insulation cover can close the storage opening.

[0116] Furthermore, it also includes a lifting mechanism 7, which can lift the transfer tank and dock it with the operating cabin 1. The operating cabin 1 has a transfer tank passage opening.

[0117] Preferably, the operating compartment 1 is also equipped with a can lid storage mechanism, which can support the can lid of the transfer tank and can hold can lids of different sizes.

The upper end of the seventh lifting frame 703 can be used to place the intermediate tank. The rotating gripping component 4 can move the channel cover on the intermediate tank channel opening to the side to facilitate docking of the intermediate tank with the operating cabin 1.

[0121] Preferably, the tandem conveyor belt 704 can connect multiple storage devices in series. The tandem conveyor belt 704 can transport the transfer tank to multiple storage devices or other devices, which greatly saves manpower.

[0122] Furthermore, the operating compartment 1 also includes an identification and storage component 8 and a rotating cleaning component 9. The identification and storage component 8 can identify the barcode of the sample or shelf, and the rotating cleaning component 9 can scan the sample or shelf.

[0123] Preferably, the identification component 8 can scan and identify the labels on the rack or sample tube, and the cleaning component 9 can clean the frost on the labels on the rack or sample tube by rotating it, so as to avoid the phenomenon of being unable to identify.

[0124] Furthermore, storage compartment 2 is equipped with a basket frame to support the basket. Storage compartment 2 is for low-temperature storage, which can ensure the activity of the sample.

[0125] In summary, this invention allows the opening assembly 6 to open the corresponding insulation cover, and the lifting hook 33 to grab or hook the basket in the storage compartment 2, raising the basket to the shelf storage channel position. Then, the shovel 51 pushes the shelf out of the basket at the shelf storage channel position, and the rotating gripping assembly 4 grabs the pushed-out shelf for the next operation. The lifting hook 33 ensures that each shelf in the basket corresponds to the shelf storage channel position. The storage component 52 places the shelf into the basket's storage slot. The rotating gripping assembly 4 can also pick out sample tubes from the shelf, and the rotating jaw 41 can rotate 360 ​​degrees. The top cover of the plate rack or transfer tank can be opened, avoiding the situation where the rotating gripper 41 cannot contact the plate rack or top cover. The lifting mechanism 7 can lift the transfer tank and dock it with the operating chamber 1. The rotating gripping component 4 can open the top cover of the intermediate tank and store the cryopreservation tubes or plate racks inside into the basket through the shovel assembly 5 and the lifting well assembly 3, thereby placing the samples into the storage chamber 2 for freezing. The cryopreservation tubes and plate racks must be scanned by the identification entry component 8 when entering and leaving the storage. Before scanning and identification, the frost on the labels of the plate racks or cryopreservation tubes can be cleaned to prevent the inability to scan. This device realizes automated operation and greatly improves work efficiency.
