Description

Technical Field

[0001] This utility model relates to the field of component analysis technology for rare earth oxides, and in particular to a component analysis device for rare earth oxides. Background Technology

[0002] In rare earth oxide composition analysis, especially using laser-induced breakdown spectroscopy (LIBS), LIBS can analyze the sample surface point by point in open or closed environments. To ensure data stability, it is necessary to keep the sample position fixed during analysis. However, existing techniques have some shortcomings in sample positioning and fixation:

[0003] Traditional methods typically rely on manual adjustment of the sample position, which is not only time-consuming and labor-intensive, but also prone to positional deviations due to inaccurate human operation. It is difficult to ensure that the sample is in exactly the same position each time it is placed, affecting the consistency and comparability of multiple measurement results. During the analysis process, the sample may be displaced due to external vibration or other interference, resulting in distorted measurement data or errors. Utility Model Content

[0028] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Please refer to Figures 1-8 This utility model provides a component analysis device for rare earth oxides, including an analytical instrument body 1. A laser 24 and an optical fiber 25 are mounted on the upper end of the analytical instrument body 1. The optical fiber 25 is supported by a bracket 26, and the other end of the optical fiber 25 is focused onto the sample surface to collect spectral information in the plasma. The laser 24 focuses the laser light onto the sample surface, exciting the sample surface to generate plasma. The optical fiber 25 collects the spectral information in the plasma. The analytical instrument body 1 analyzes the collected spectral information to obtain the elemental composition and elemental content in the sample. At the same time, through the change of the laser focusing point, qualitative and quantitative analysis of elements at different points on the sample surface can be achieved.

[0030] A base 7 is provided on one side of the upper part of the analytical instrument body 1. One end of the optical fiber 25 passes through the bottom of the base 7 without affecting the use of the glass cover 4. A central rod 10 is fixedly provided at the upper part of the base 7, and a feeding plate 11 is provided at the top of the central rod 10. The sample is placed on the feeding plate 11. A slot 8 is opened near the outer part of the base 7. The glass cover 4 is clamped in the slot 8. The glass cover 4 is then clamped in the slot 8 to seal the sample from all sides. In addition, a support plate 5 is fixedly provided on one side of the analytical instrument body 1. A sealing cover 6 is hinged to the opposite end of the support plate 5. The sealing cover 6 seals the end of the glass cover 4. The sealing cover 6 is rotated to the upper end of the glass cover 4 to seal the sample and ensure that the entire system is in a closed state.

[0031] To ensure that the sample is accurately placed in the appropriate position on the feeding plate 11, through holes 13 are symmetrically provided on the feeding plate 11. A positioning mechanism is slidably installed in the through holes 13. The positioning mechanism includes a positioning head 14 that slides in the through hole 13. A base block 15 is fixedly connected to the lower end of the positioning head 14. The base block 15 extends from the through hole 13 to the bottom of the feeding plate 11. A fixing plate 16 is symmetrically provided on the lower side of the feeding plate 11. A spring 18 is connected between the fixing plate 16 and the base block 15. When the sample is placed between the two sets of positioning heads 14, the elastic contraction of the spring 18 makes the positioning head 14 fit tightly against both sides of the sample, so that the sample is stably placed on the feeding plate 11.

[0032] In addition, a groove 17 is provided on the lower side of the fixing plate 16, and the protrusion on the lower side of the bottom block 15 slides in the groove 17, making the bottom block 15 more stable when moving.

[0033] Furthermore, a limiting block 12 is provided on the upper side of the feeding plate 11. The limiting block 12 provides a base point for the placement of the sample. When one side of the sample is placed in contact with the limiting block 12, the sample is precisely placed between the two sets of positioning heads 14.

[0034] Considering that it is inconvenient to remove the sample after it is fixed, an inner groove 9 is provided on the inner side of the base 7. A pushing mechanism is inserted into the inner groove 9 and pushes the positioning mechanism.

[0035] The pushing mechanism includes a sleeve 19 inserted into the inner groove 9. The sleeve 19 is sleeved on the outside of the middle rod 10. The upper end of the sleeve 19 is threadedly connected to an end head 20. Both sides of the end head 20 are provided with push rods 21. The end of the push rod 21 is fixedly provided with a push block 22. The upper side of the push block 22 fits against the lower side of the bottom block 15. Both the bottom block 15 and the push block 22 are wedge-shaped block structures. Therefore, when the sleeve 19 is slid upward, the push block 22 can push the bottom block 15, causing the bottom block 15 to slide towards one end of the slide groove 17 and be squeezed by the spring 18, so that the sample can be easily taken out. When the push block 22 is reset, the spring 18 causes the positioning head 14 to reset.

[0036] A frustum 2 is provided on the other side of the upper part of the analytical instrument body 1. The frustum 2 is used to place the glass cover 4. When it is necessary to remove the sample, the sealing cap 6 must first be separated from the glass cover 4, and then the glass cover 4 can be removed. The glass cover 4 can be placed on the frustum 2 to reduce the stains on the glass cover 4.

[0037] It is worth noting that a dust cover 23 is threadedly connected to the outside of the frustum 2. The dust cover 23 seals the frustum 2 and reduces the entry of dust and dirt. Symmetrical mounting brackets 3 are provided on the side wall of the analyzer body 1. When the dust cover 23 is removed, it is stored in the mounting brackets 3.

[0038] In summary, the working principle of the rare earth oxide component analysis device of this utility model embodiment is as follows: the sample is placed on the feeding plate 11, the limiting block 12 and the positioning head 14 cooperate with the spring 18 to fix the sample, the glass cover 4 is installed and sealed with the sealing cover 6 to form a sealed environment, the laser 24 focuses the laser on the sample surface to excite the sample surface to generate plasma, the optical fiber 25 collects the spectral information in the plasma, the analysis instrument body 1 analyzes the collected spectral information to obtain the elemental composition and elemental content in the sample, and when sampling, the glass cover 4 is removed, the sleeve 19 is slid upward to make the push block 22 push the bottom block 15 to release the sample.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
