Abstract

The invention relates to a multi-station sample sending and recycling device used for electrostatic suspension and a using method thereof. A first stepping motor is connected with a sample plate through a metal rod; a sample transport rod is connected with a second stepping motor, so that the sample transport rod moves in the vertial direction; the processing steps are as follows: closing a cavity, vacuumizing, transporting target samples from the initial position of the sample plate to a suspension starting position; after finishing electrostatic suspension experiment for the target samples,recycling the target samples. According to the invention, by reasonably designing a mechanical transport mechanism and a control process, the multi-station sample transport device and the method are provided, sending and recycling a plurality of samples in the closed cavity are achieved. The multi-station sample sending and recycling device provided by the invention is characterized in that numerous samples can be processed, the processing sequence is flexible, the processing procedure has no impacts on vacuum degree, and the adaptability is wide.

Description

technical field [0001] The invention belongs to the technical field of new material preparation and electrostatic levitation, relates to a material transmission and recovery method, in particular to a multi-station sample delivery and recovery device for electrostatic levitation and its use method. Background technique [0002] Electrostatic levitation containerless processing technology can be independently controlled for levitation and heating, avoiding the influence of forced convection inside the levitation liquid state caused by electromagnetic stirring, ultrasonic cavitation, and airflow disturbance on the material properties, and thus applied to many frontier fields. Such as thermophysical property measurement and single crystal growth of high melting point refractory metals and alloys in a wide temperature range, further, combined with external detection equipment (high-speed camera, photodiode, neutron scattering and synchrotron radiation experiments, etc.), high tem...
