Batch sample experimental device

Abstract

The invention relates to a batch sample experimental device, which comprises sample banks, a multi-dimensional moving mechanism, a mechanical hand, a sample locking mechanism and a heating furnace. The mechanical hand comprises a mechanical main hand, a mechanical auxiliary hand, a positioning screw cap, a buffering spring and an encoder. The sample locking mechanism comprises a locking screw core, a clamping cabin locking nut and a clamping cabin which are arranged in coaxial mode. The multi-dimensional moving mechanism comprises a hand body vertical support and a horizontal lead screw, and accordingly vertical and horizontal movement of the mechanical hand, the front and back movement of the sample banks and the front and back movement of the furnace are achieved. The sample banks and the heating furnace are arranged on the same vertical position, two sample banks are arranged on the upper side and the lower side of the device, and the heating furnace is arranged between the two sample banks. By means of the batch sample experimental device, replacing, experiment and processing of mass samples can be achieved in full automation mode, and the processes of replacing, experiment and processing do not need manual intervention.

Description

technical field [0001] The field of experimental device design of the present invention, in particular, relates to a batch sample experimental device, which is particularly suitable for the experiment and processing of a large number of samples with similar experimental and processing procedures, such as alloy experiments with different components and different component ratios; and it It is also particularly suitable for carrying out scientific experiments in unattended conditions in space. Background technique [0002] In the current batch sample experimental device in my country, the mechanism used to drive the sample ampoule into and out of the feed bin is only a shift fork. It is very simple, it picks the head of the sample ampoule and drives the sample ampoule to move. It does not allow for no resistance between the sample ampoule and the silo when the sample ampule is moving in the silo. The consequence of this is that during the space experiment, the friction force...

Problems solved by technology

The consequence of this is that during the space experiment, the friction force will seriously damage the microgravity state of the sample in the space science experiment, and in severe cases, it will lead to the failure of the space science experiment; it is easy to cause scratches on the surface of the sample ampoule, and even damage the used Sample ampoule made of quartz, and the fork is not able to transmit the measurement signal of the sample in the sample ampoule

[0003] Moreover, there are many deficiencies in the current batch sample experimental device, for example: the number of samples loaded in the experimental device is small, and only 6 samples can be processed at most at one time. It is used for space material science experiments on the Shenzhou 3 spacecraft; It is also easy to cause damage to the sample ampoule due to the resistance between the sample ampoule and the hopper, etc., which affects the application of these devices in material science experiments
