Description

Technical Field

[0001] This utility model relates to the field of infrared spectroscopy analysis technology, specifically to an installation and adjustment mechanism and an infrared spectroscopy analyzer. Background Technology

[0002] Germanium tetrachloride is an important inorganic compound used to manufacture high-purity germanium single crystals, which are key materials for semiconductor devices. It is also used for vapor phase epitaxial deposition of germanium thin films to manufacture high-efficiency solar cells and optoelectronic devices.

[0003] Germanium tetrachloride needs to be placed in a sample cell for infrared spectroscopy detection. The sample cell consists of a quartz columnar cell and a germanium lens. An inlet pipe and an outlet pipe are connected to the quartz cell. The inlet and outlet pipes are sealed with simple, removable caps. The germanium lens is fixed with a steel ring and epoxy resin casting.

[0004] Since the height of the detection light source inside an infrared spectrometer cannot be changed, it is difficult to ensure that the germanium lens of each sample cell corresponds to the detection light source when different types of sample cells are placed inside the infrared spectrometer for detection. This makes it inconvenient for the infrared spectrometer to detect samples in different types of sample cells. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] To address the technical problem in existing technologies where different sample cell models make it difficult to ensure that the lens at the end of the sample cell corresponds to the detection light source when placed within an infrared spectroscopy analyzer, this invention provides an installation and adjustment mechanism and an infrared spectroscopy analyzer that can adjust the position and height of the sample cell, ensuring that the lens at the end of the sample cell corresponds to the detection light source within the infrared spectroscopy analyzer.

[0027] Please see Figures 1-5 , Figures 1-5This utility model discloses an installation and adjustment mechanism for adjusting the position and height of a sample cell. It includes a lifting unit 1 and an adjustment unit 2. The lifting unit 1 includes a movable plate 10, which is capable of being raised and lowered. The adjustment unit 2 includes a positioning member 21, which has a groove 21a that matches the connecting pipe of the sample cell. The positioning member 21 is mounted on the movable plate 10. The positioning member 21 and the movable plate 10 have a first state and a second state. In the first state, the positioning member 21 can move relative to the movable plate 10. In the second state, the positioning member 21 is fixed to the movable plate 10.

[0028] In actual use, the sample cell connecting tube is inserted into the groove 21a, and the sample cell can be suspended on the movable plate 10. By adjusting the movement of the movable plate 10, the sample cell can be extended into the detection cavity of the infrared spectrometer, and the lens at the end of the sample cell can be aligned with the detection light source on the side wall of the detection cavity.

[0029] It should be noted that the sample cell is a sample cell for infrared detection of germanium tetrachloride and silicon tetrachloride disclosed in the existing patent application document CN103900960A. The sample cell contains germanium tetrachloride, and this solution can detect germanium tetrachloride in the sample cell using an infrared spectrometer.

[0030] The infrared spectrometer is not limited to a specific structure, and no other limitations are made here. In one embodiment, the infrared spectrometer has a detection cavity, and the side wall of the detection cavity is provided with a detection light source.

[0031] It should be noted that the positioning component 21 is not limited to a specific structure. In one embodiment, the movable plate 10 has a through hole. The positioning component 21 includes a base 211, a locking screw 212, and a locking nut 213. The base 211 has a groove 21a. The base 211 is slidably connected to the movable plate 10. One end of the locking screw 212 is fixedly connected to the base 211. The locking screw 212 passes through the through hole, and the other end is screwed into the locking nut 213.

[0032] Specifically, the movable plate 10 is provided with a through hole, and the base 211 is provided with two protrusions. The two protrusions are slidably locked in the two through holes. In the first state, the locking nut 213 and the locking screw 212 are not fully tightened, and the locking screw can be pushed to slide along the through hole to adjust the position of the base 211 in the horizontal direction.

[0033] It should be noted that the groove 21a is a V-shaped groove. The adjustment unit 2 also includes a locking member 22, which includes a connecting block 221 and an adjusting screw 222. The adjusting screw 222 is threadedly rotatably connected to the connecting block 221. The connecting block 221 is detachably connected to the base 211, and one end of the adjusting screw 222 can extend into the groove 21a.

[0034] It should be noted that, since the sample cells are of different models and sizes, the outer diameter of the connecting pipe of the sample cell is also different. By adjusting the screw 222, one end of the adjusting screw 222 is made to abut against the connecting pipe of the sample cell, so as to fix the sample cells of different models and improve the installation stability of the sample cells.

[0035] It is understood that the sample pool connecting tube can only be opened in the groove 21a after the connecting block 221 is separated from the base 211. In one embodiment, the base 211 has sliding grooves on both sides, and the connecting block 221 is provided with two sliders, which can move into / out of the two sliding grooves respectively. Specifically, when the two sliders move out of the two sliding grooves respectively, the connecting block 221 can be separated from the base 211.

[0036] Based on the above scheme, in order to avoid the adjusting screw 222 damaging the connecting tube of the sample cell, specifically, one end of the adjusting screw 222 is provided with a pressure block 223, the pressure block 223 is hemispherical and made of elastic rubber block.

[0037] It should be noted that, in one embodiment, the lifting unit 1 further includes a base plate 11, two guide rods 12, a threaded screw 13, and a top plate 14. The two guide rods 12 are fixed between the base plate 11 and the top plate 14, and the threaded screw 13 is rotatably disposed between the base plate 11 and the top plate 14. The movable plate 10 is slidably connected to the two guide rods 12 and threadedly rotatably connected to the threaded screw 13.

[0038] It is understandable that by rotating the screw 13, the movable plate 10 can be driven to rise or fall, thereby adjusting the position and height of the sample cell suspended on the movable plate 10.

[0039] Based on the above scheme, in order to ensure the stability of the installation and adjustment mechanism, the lifting unit 1 further includes a counterweight 15, which is set on the base plate 11. The counterweight 15 can prevent the installation and adjustment mechanism from tipping over when the sample pool is suspended on the movable plate 10.

[0040] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
