Description

Technical Field

[0001] This utility model relates to the field of spectrometer technology, and in particular to an X-ray fluorescence spectrometer. Background Technology

[0002] X-ray fluorescence spectrometry (XRF) is a device used for elemental analysis. It determines the elemental composition of a sample by analyzing its fluorescence response to X-rays. This instrument is widely used in environmental monitoring, materials analysis, and quality control, enabling efficient and non-destructive qualitative and quantitative elemental analysis.

[0003] Traditional X-ray fluorescence spectrometers consist of several key components, including an X-ray source, sample position, and detector. The X-ray source generates rays that irradiate the sample; after absorbing the X-rays, the sample emits fluorescence, which is then collected and analyzed by the detector. The sample position typically needs to be precisely controlled to ensure the accuracy of the test.

[0004] Traditional X-ray fluorescence spectrometers are inconvenient to adjust when detecting objects. Sample positioning and angle adjustment usually rely on manual operation, which makes the adjustment process cumbersome and time-consuming. Moreover, some traditional instruments lack flexible automatic adjustment functions, resulting in the inability to achieve optimal measurement results when detecting samples of different shapes, sizes, or positions. This not only increases operational complexity but also affects the accuracy and efficiency of detection, prolongs analysis time, and reduces the overall working efficiency of the instrument. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an X-ray fluorescence spectrometer, which aims to improve the problem that the inconvenience of adjustment when detecting objects in traditional X-ray fluorescence spectrometers affects the accuracy and efficiency of detection, prolongs the analysis time, and reduces the overall working efficiency of the instrument.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an X-ray fluorescence spectrometer, comprising a body, a detection cover provided on the top of the body, a detection stage provided inside the body, and an adjustment component provided at the bottom of the detection stage; The adjustment assembly includes a base plate disposed at the bottom of the testing platform.

A sliding column is slidably connected inside the turntable and is slidably connected inside the multiple rotating frames. The top end of the sliding column is fixedly connected to the lower surface of the testing platform. A control assembly is disposed at the bottom of the base plate.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3 An embodiment of this utility model is provided: an X-ray fluorescence spectrometer, including a body 1, a detection cover 2 on the top of the body 1, a detection stage 3 inside the body 1, and an adjustment component at the bottom of the detection stage 3; The adjustment assembly includes a base plate 4, which is located at the bottom of the testing table 3. Multiple side plates 5 are fixedly connected to the side walls of the base plate 4. Two side plates 5 are fixedly connected to the side walls of the side plates 5. A rotating frame 7 is fixedly connected to the output end of each motor 6. A turntable 8 is rotatably connected to the upper surface of the base plate 4. A sliding column 9 is slidably connected inside the turntable 8. The sliding column 9 is slidably connected inside the multiple rotating frames 7. The top of the sliding column 9 is fixedly connected to the lower surface of the testing table 3. A control assembly is provided at the bottom of the base plate 4.

[0020] Reference Figure 4 The control assembly includes a base platform 10, which is located at the bottom of a base plate 4. A slide rod 12 is slidably connected inside the base platform 10. A support platform 11 is fixedly connected to the top of the slide rod 12 and is fixedly connected to the bottom of the base plate 4. A rack 13 is fixedly connected to the side wall of the slide rod 12. An electric motor 14 is fixedly connected to the upper surface of the base platform 10. A worm gear 15 is fixedly connected to the output end of the electric motor 14. A side platform 16 is fixedly connected to the upper surface of the base platform 10. One end of the worm gear 15 is rotatably connected inside the side platform 16. A side frame 17 is fixedly connected to the upper surface of the base platform 10. A worm wheel 18 is rotatably connected to the side wall of the side frame 17. The worm wheel 18 meshes with the worm gear 15. A gear 19 is fixedly connected to the side wall of the worm wheel 18 and meshes with the rack 13.

[0021] Working Principle: When adjusting the sample to be tested, the motor 6 on side plate 5 is started. Its output drives the rotating frame 7 to rotate. The rotating frame 7, through the sliding column 9, pushes the detection stage 3 on the base plate 4 to adjust its angle. Since the sliding column 9 can slide within the rotating platform 8 and is rotatably connected to the rotating frame 7, when the motors 6 on both sides rotate synchronously or asynchronously, the rotating frame 7 drives the sliding column 9 to swing, causing the detection stage 3 to tilt or move horizontally around the axis of the rotating platform 8, achieving multi-angle adjustment of the detection surface and accurately aligning it with the X-ray source and detector. After the electric motor 14 starts, the worm gear 15 at its output end drives the worm wheel 18 to rotate. The gear 19 on the side wall of the worm wheel 18 meshes with the rack 13, driving the sliding rod 12 to slide up and down within the base plate 10. The support platform 11 at the top of the sliding rod 12 rises and falls accordingly, driving the overall height adjustment of the base plate 4 and the detection stage 3. The self-locking characteristics of the worm wheel 18 and worm gear 15 ensure stable position after adjustment. By controlling the direction and speed of the electric motor 14, the lifting distance of the detection stage 3 can be precisely controlled to adapt to the testing needs of samples at different heights.
