Description

Technical Field

[0001] The invention relates to the technical field of electron microscope control, and in particular to a transmission electron microscope sample rod control console and a use method thereof. Background Art

[0002] A transmission electron microscope is a microscope that uses a focused electron beam as a light source, and its resolution can reach the atomic scale. A transmission electron microscope can not only observe the morphology of a sample, but also obtain diffraction information of the sample. The three-dimensional electron diffraction technology based on a transmission electron microscope can analyze the atomic structure of nano-sized crystals thanks to the micro-area analysis capability of the electron beam. Compared with traditional single crystal X-ray diffraction technology, the three-dimensional electron diffraction technology has smaller requirements on the crystal size.

[0003] The three-dimensional electron diffraction technique is a single crystal diffraction experiment that uses the sample rod as the rotation axis to realize uniaxial rotation in the transmission electron microscope. Its data collection is essentially to sequentially record the diffraction patterns obtained by the transmission electron microscope goniometer at different rotation angles. There are two main methods for collecting data for three-dimensional electron diffraction. One is step-by-step data collection. Every time the goniometer rotates, it is necessary to check whether the position of the sample is in the center of the light source, and then collect the diffraction pattern. The data collection time is usually about 30 minutes. The other is continuous data collection. The goniometer rotates continuously within the rotatable range, and the detector collects the diffraction pattern during the rotation process like recording a video. The data collection time of this method only takes a few minutes, which is more beneficial for samples sensitive to electron beams. However, this method has high requirements for the mechanical stability of the goniometer during the rotation process. Ideally, the drift range of the sample during the entire rotation process should be smaller than the electron beam irradiation area, so as to collect complete data. However, the mechanical stability of the goniometer of the common transmission electron microscope is difficult to meet such requirements. During the continuous rotation data collection process, the sample often drifts outside the light source and the diffraction signal disappears, resulting in interruption of data collection.

[0042] Working process: In actual use, if the sample rod is to be moved to the right, it is necessary to send a start movement instruction to the first high-precision motor 6, the first screw rod rotates and drives the first high-precision electric translation stage 8 to move to the left, and the sample rod is pushed to the right by the first transmission lever 9, and the first reverse positioning spring 10 on the right side of the sample rod is compressed; if the sample rod is to be moved to the left, it is necessary to send a movement instruction opposite to the previous one to the first high-precision motor 6, the first screw rod rotates and drives the first high-precision translation stage to move to the right, and the first reverse positioning spring 10 on the right side of the sample rod slowly resets, pushing the sample rod to move to the left. Similarly, if the sample rod is to be moved upward, it is necessary to send a start movement instruction to the second high-precision motor 12, the second screw rotates and drives the second high-precision translation stage to move to the right, the ball 17 on one side of the sample rod is gradually lifted, thereby driving the sample rod to move upward, and the two reverse positioning springs on the other side of the sample rod are compressed; if the sample rod is to be moved downward, it is necessary to send a movement instruction opposite to the previous one to the second high-precision motor 12 below, the second screw rotates and drives the translation stage to move to the left, the two second reverse positioning springs 15 above the sample rod are gradually reset, and the sample rod is pressed downward, so that the ball 17 below the sample rod contacts the smooth inclined surface.

[0043] Embodiment 2: The difference between this embodiment and embodiment 1 lies in that, in this embodiment, both sides of the connecting plate 1 are provided with slide grooves 20, and the slide grooves 20 are through grooves; a first hinge block 18 is fixedly connected to one side of the outer side of the connecting plate 1, and the first hinge block 18 is fixedly arranged on one side of the slide groove 20 and is fixedly connected to the connecting plate 1; two groups of second hinge blocks 21 are symmetrically arranged on both sides of the base plate 2, and the second hinge blocks 21 are fixedly connected to the base plate 2, and the second hinge blocks 21 are adapted to the slide groove 20; a connecting rod assembly is hinged between the second hinge block 21 and the first hinge block 18, and the connecting rod assembly includes a first connecting rod 19 and a second connecting rod, and the first connecting rod 19 and the second connecting rod are hinged to each other; pressing the hinge point of the two connecting rods can push the base plate 2 to slide on the connecting plate 1.

The second hinge block 21 is fixed by an external bolt or a block to fix the bottom plate 2 and the connecting plate 1. When pulled back, the spring 23 is reset to return the bottom plate 2 to its initial position.
