Intelligent sample storage mechanism

Abstract

The invention relates to an intelligent sample storage mechanism which comprises a plate frame storing and taking mechanism. The plate frame storing and taking mechanism comprises an operation cabin, a plate frame claw hand assembly located in the operation cabin, a plate frame conveying assembly, a plate frame storing and taking assembly, a basket lifting assembly and a tank cover operation assembly. A transfer tank operation opening and a liquid nitrogen tank operation opening are formed in the bottom wall of the operation cabin; the plate frame claw hand assembly comprises a transverse movement driving module and a plate frame extracting device, and the plate frame extracting device comprises a plate frame claw hand and a plate frame lifting device; the plate frame conveying assembly comprises a conveying plate and a conveying plate driving device; the plate frame storing and taking assembly comprises a first push plate mechanism and a second push plate mechanism, and the first push plate mechanism and the second push plate mechanism each comprise a push plate and a push plate driving device; the basket lifting assembly comprises a lifting frame and a lifting frame lifting device; and the tank cover operation assembly comprises a temporary storage frame and a temporary storage frame driving device. The intelligent sample storage mechanism can automatically store and take plate frames, biological samples are not prone to damage, and operation is convenient and fast.

Description

technical field [0001] The invention relates to a biological sample storage device, in particular to a sample intelligent storage mechanism. Background technique [0002] In the field of biological preservation, biological samples are generally stored in cryogenic liquid nitrogen tanks. During storage, the operator stores the samples in cryovials, places them on the racks, and finally stores the racks containing biological samples in liquid nitrogen tanks. The rack is generally transferred through a transfer tank, and after it is transferred to the destination, the operator manually puts it into a liquid nitrogen tank in a deep and low temperature environment for storage. When taking the plate frame, the operator can follow the above-mentioned reverse procedure. This type of rack access method cannot realize automatic access to the entire plate rack, and its access efficiency is low. At the same time, the organisms are easily exposed to normal temperature during the transf...

AI Technical Summary

Problems solved by technology

This type of rack access method cannot realize automatic access to the entire plate rack, and its access efficiency is low. At the same time, the organisms are easily exposed to normal temperature during the transfer process, which increases the risk of damage to biological samples. Reduced work efficiency

[0003] To sum up, the above common rack storage method reduces the access efficiency, cannot realize the intelligent operation of the rack, easily exposes the stored biological samples to normal temperature, reduces the activity of biological samples, and brings users inconvenient
