Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of biological sample storage and access, and particularly relates to an integrated biological sample transfer mechanism. BACKGROUND

[0002] A biological sample bank, also known as a biological bank, is a storage library in which samples are classified and stored in a low-temperature storage refrigerator and can be automatically and intelligently accessed. The main automated equipment access device is a sample transfer device, which is composed of a cryopreservation rack transfer module, a cryopreservation box transfer module, and a cryopreservation tube transfer module.

[0003] Currently, the traditional sample transfer process is that the cryopreservation rack transfer module first takes out a cryopreservation rack to be taken out from a refrigerator, then moves the cryopreservation rack to a temporary storage refrigerator, then the cryopreservation box transfer module in the temporary storage refrigerator takes out the cryopreservation box to be taken out from the cryopreservation rack to be taken out, then the cryopreservation rack transfer module puts the taken-out cryopreservation rack back and takes out the next cryopreservation rack, at the same time, the cryopreservation box transfer module transfers the taken-out cryopreservation box to a tube picking platform, and finally the cryopreservation tube transfer module transfers the cryopreservation tube to be taken out in the taken-out cryopreservation box to an empty cryopreservation box.

[0004] Due to the large volume of the biological sample bank, the cryopreservation rack transfer module wastes a long time in transferring cryopreservation racks at a far position, and the cryopreservation tube transfer module cannot work continuously. After transferring the cryopreservation tubes to be taken out in a target cryopreservation box, the cryopreservation tube transfer module needs to wait for the cryopreservation box transfer module to put the taken-out cryopreservation box back and transfer a new cryopreservation box to be taken out before continuing to perform the cryopreservation tube picking work. When a large number of different cryopreservation racks or different cryopreservation boxes on the same cryopreservation rack need to be taken out, the efficiency is very low. Therefore, it is urgent to research an integrated biological sample transfer mechanism to solve the above problems. SUMMARY
