Sample transfer device for biological sample library

Abstract

The invention relates to the technical field of low-temperature storage, provides a sample transfer device for a biological sample library, and designs an X-axis track, a Y-axis track and a Z-axis track for carrying a manipulator to move so that the manipulator takes and moves biological samples on a treatment table according to design requirements. Through an automatic treatment table and a manual treatment table, the information of different biological samples can be rapidly and efficiently input, different biological sample reagents can be selected, the working efficiency of the biological sample library is improved, and the application range of the biological sample library is widened. The manipulator is provided with a first manipulator rack, a second manipulator rack and a driving gear shaft transmission mechanism meshed with the first manipulator rack and the second manipulator rack, and in the rotating process of a driving gear shaft, the first manipulator rack and the second manipulator rack are driven to move in opposite directions; and the grabbing and releasing actions of the first manipulator arm and the second manipulator arm can be completed only by controlling forward rotation and reverse rotation of the driving motor connected with the driving gear shaft, and the efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of low-temperature storage, in particular to a sample transfer device for a biological sample bank. Background technique [0002] With the development of biomedicine, the requirements for automation of biological sample banks and vaccine banks are getting higher and higher. Biological samples are usually frozen in sample test tubes, which are placed on storage shelves through sample boxes and refrigerated in a low-temperature environment to ensure the stability of the samples and extend the storage time. [0003] In the ultra-low temperature environment, the storage of biological samples needs to adopt automatic picking equipment. In the existing technology, the grabbing manipulator has complex structure, cumbersome control process, and poor action execution efficiency, which cannot meet the requirements of fast grabbing and quick transfer of multiple biological samples. At the same time, the biological sam...

[0003] In the ultra-low temperature environment, the storage of biological samples needs to adopt automatic picking equipment. In the existing technology, the grabbing manipulator has complex structure, cumbersome control process, and poor action execution efficiency, which cannot meet the requirements of fast grabbing and quick transfer of multiple biological samples. At the same time, the biological sample bank needs to store different biological samples or vaccines, etc., and a transfer area is required to input or retrieve information on different biological samples and vaccines through the transfer device and the information manually entered.
