Embodiment 1

[0053] A sample pretreatment mechanism provided by an embodiment of the present invention includes:

[0054] A sample introduction assembly 500; the sample introduction assembly 500 includes a sample tray 501 and a first drive member for driving the sample tray 501 to rotate; the sample tray 501 has a plurality of sample positions arranged in a circle;

[0055] A sampling component 300, configured to grab a sample 1 from the sample position;

[0056] Sample grinding assembly 100, used for grinding sample 1;

[0057]The transfer assembly 200 is used to drive the sampling assembly 300 to reciprocate along the x-axis, y-axis and z-axis direction, so that the sampling assembly 300 grabs the sample 1 from the sample position, and transfers the grabbed sample 1 to the grinding sample assembly 100 to perform grinding, and transfer the polished sample 1 to a designated position; or realize that the sampling component 300 directly transfers the sample 1 grasped from the sample positio...

Embodiment 2

[0099] as attached figure 1 As shown, an embodiment of the present invention also provides a kind of automatic analysis system for direct-reading spectrometer, comprising:

[0100] Direct reading spectrometer 800, used to analyze the element content of sample 1;

[0101] The sample pretreatment mechanism described in any one of Embodiment 1; the transfer assembly 200 in the sample pretreatment mechanism drives the sampling assembly 300 to transfer the polished sample 1 to the direct-reading spectrometer 800, or drives the sampling assembly 300 to directly transfer the sample 1 from The sample 1 grabbed by the sample position is transferred to the direct reading spectrometer 800 .

[0102] In this embodiment, the direct-reading spectrometer 800 is connected with the sample pretreatment mechanism in Embodiment 1 through a frame 900 to form a whole.

[0103] The working principle of the embodiment of the present invention is as follows:

[0104]The mechanical claw 303 transfer...

Abstract

The invention is suitable for the technical field of direct-reading spectrum detection equipment, and provides a sample pretreatment mechanism, which comprises a sample introduction assembly, a sampling assembly, a sample grinding assembly and a transfer assembly. The sampling assembly is driven by the transferring assembly to reciprocate in the x-axis direction, the y-axis direction and the z-axis direction, so that the sampling assembly grabs a sample from a sample position, the grabbed sample is transferred to the sample grinding assembly to be ground, and the ground sample is transferred to a designated position; or the sampling assembly directly transfers the sample grabbed from the sample position to a designated position, so that traditional manual sample pretreatment is converted into mechanical sample pretreatment, on one hand, the detection efficiency is improved, on the other hand, huge workload can be dealt with, operation errors caused by exhaustion of operators are avoided, and the safety of operators is ensured; and the labor intensity of the operators is reduced. The invention further provides a full-automatic analysis system which comprises the sample pretreatment mechanism and is used for the direct-reading spectrometer.

Description

technical field [0001] The invention belongs to the technical field of direct-reading spectrometer detection equipment, and in particular relates to a sample preprocessing mechanism and a fully automatic analysis system for direct-reading spectrometers. Background technique [0002] The direct-reading spectrometer is an instrument for quickly analyzing the element content of metals. It adopts the analysis principle of atomic emission spectroscopy. The sample is excited by an electric arc or spark discharge to form an atomic vapor. After the atoms or ions in the vapor are excited, an emission spectrum is generated. The spectrum enters the spectrometer through the optical fiber and is dispersed into various spectral bands. According to the emission wavelength range of each element, the best spectral line of each element is measured by the photocell. The intensity of the emission spectral line of each element is proportional to the content of the element in the sample. , the co...
