Cryoelectron microscope sample transfer system and method and electronic equipment

Abstract

The invention belongs to the technical field of scanning electron microscopes, particularly relates to a cryoelectron microscope sample transfer system and method and electronic equipment, and aims to solve the problem that a cryoelectron microscope sample changes in the transfer process. The system comprises a master control center, a transfer table base, a transfer device, a transmission rod, a moving device, a rotating device and a vacuum docking mechanism. The moving device comprises a first power device, a first transmission assembly, a transmission lead screw, a transfer rod sliding rail, a moving sliding block and a limiting sliding block. The rotating device comprises a second power device and a second transmission assembly; a moving assembly composed of a moving sliding block, a limiting sliding block and a transmission rod moves to the transmission rod to be in butt joint with the transfer device, and the limiting sliding block and a second transmission assembly are locked; a rotating assembly composed of a transmission rod, a limiting sliding block and a second transmission assembly rotates to the transmission rod and is locked with the transfer device; the transfer device and the moving assembly move to the vacuum docking mechanism; the structure and the property of the sample are effectively prevented from being changed in the transfer process.

Description

technical field [0001] The invention belongs to the technical field of scanning electron microscopes, and in particular relates to a cryo-electron microscope sample transfer system, method and electronic equipment. Background technique [0002] The sample room of the conventional scanning electron microscope is a high vacuum environment, which requires the observation sample to be dry and non-volatile. However, many samples contain water, oil or are volatile, so they cannot meet the conditions of the conventional electron microscope. At the same time, the loss of water and oil will also cause sample structure, The nature changes and the test data is distorted. The cryo-scanning electron microscope developed in recent years makes it possible to observe natural gas hydrates, oil-bearing rocks, biological cells, suspensions, hydrogels and other water-containing and oil-containing samples that cannot be observed by conventional electron microscopes with the help of ultra-low tem...
