Description

Technical Field

[0001] This utility model belongs to the field of tin oxide detection technology, and specifically relates to a device for detecting the tin oxide content in ITO powder. Background Technology

[0002] ITO powder possesses many excellent physical and chemical properties. Electrically, it exhibits excellent conductivity, making it widely used in the electronics field. Optically, it boasts high transparency, especially in the visible light range. This transparent conductivity makes it an ideal material for manufacturing transparent conductive electrodes. Chemically, it resists the erosion of various chemicals, allowing it to function effectively in complex chemical environments. It is a key raw material for manufacturing devices such as flat panel displays and solar cells. For example, in liquid crystal displays and organic light-emitting diode displays, it is used to manufacture transparent conductive electrodes, enabling efficient electron transport without affecting the screen's light transmittance. In the field of solar cells, it also helps improve the photoelectric conversion efficiency of the cells.

[0003] Currently, during the application of ITO powder, it is usually necessary to detect its internal tin oxide content. Existing detection methods typically use X-ray fluorescence spectrometry. However, existing X-ray fluorescence spectrometers still have certain defects and shortcomings in application:

[0004] For example, Chinese patent with publication number "CN217156360U" discloses an X-ray fluorescence spectrometer for RoHS testing, which includes a spectrometer, a stage, and a lifting mechanism. The stage is slidably connected inside the spectrometer and passes through the upper side of the spectrometer. The lifting mechanism is connected inside the spectrometer. The bevel gear on the lower side of the second lead screw of this invention rotates, which drives the second lead screw to rotate, thereby enabling the slider and the stage to move upward.

[0005] While the aforementioned equipment possesses certain unique design features, it also exhibits significant drawbacks. Firstly, the lifting structure is concealed internally. When maintenance is required, the deep placement of the lifting structure necessitates extensive disassembly by maintenance personnel, demanding considerable time and effort. This not only increases maintenance difficulty and cost but also risks damaging other parts of the equipment during disassembly, potentially jeopardizing its overall performance and lifespan. Secondly, in daily use, the loading and unloading of test samples relies entirely on manual handling of sample trays, resulting in low efficiency. Operators frequently perform repetitive tasks, wasting time and energy, increasing workload, and leading to fatigue and boredom. Furthermore, manual operation is subjective and unstable, inevitably resulting in material placement deviations that may affect the accuracy and reliability of test results. In short, the equipment is flawed, inconvenient, and fails to meet the demands of modern, efficient, and precise testing. Improvements are urgently needed to enhance performance and practicality, better adapting to real-world applications. Utility Model Content

The first lead screw is rotatably connected to the inside of the rail frame, and a slider is threadedly connected to the outer surface of the first lead screw. The top of the slider is fixedly connected to the bottom of the rotating support component. The slider has a rectangular shape, and the inner side of the rail frame is also rectangular. Wear-resistant pads are fixedly connected to the outer surface of the slider and the inner wall of the rail frame.

[0011] As a preferred technical solution, the rotating lifting assembly includes a second motor, which is fixedly installed on the top of the slider. A support shaft is fixedly installed at the output end of the second motor, and a triangular bracket is fixedly installed on the top of the support shaft.

The triangular bracket is made of lightweight aluminum alloy, and all the outer corners of the triangular bracket are rounded.

[0012] As a preferred technical solution, the clamping assembly includes a concave frame, which is fixedly installed on the outer end of the triangular bracket. Electric push rods are fixedly installed on both sides of the concave frame. The output end of the electric push rod passes through the concave frame and is fixedly installed with a clamping seat.

[0013] As a preferred technical solution, a controller is fixedly connected to the lower front end of the X-ray fluorescence spectrometer, a display screen is provided at the upper front end of the controller, and a control keyboard is provided at the lower front end of the controller. The overall side shape of the controller is a right-angled triangle, and both the control keyboard and the display screen are located on the inclined surface of the controller.

[0014] As a preferred technical solution, the lifting mechanism includes a vertical rail, which is fixedly installed on the back of the X-ray fluorescence spectrometer. A third motor is fixedly installed at the bottom of the vertical rail, and a second lead screw is fixedly installed through the output end of the third motor through the vertical rail.

Activating the third motor drives the second lead screw inside the vertical rail to rotate, thereby causing the slide to slide inside the vertical rail. This allows the detection stage to move flexibly inside the X-ray fluorescence spectrometer, moving up and down or even being pulled out of the instrument. The lifting mechanism is located outside the instrument, so when maintenance is required, it is not necessary to enter the instrument; it can be performed directly from the outside, greatly improving convenience. This allows the device to perform detection operations more flexibly during use, significantly improving the convenience of sample handling and placement, greatly facilitating the use and maintenance of the equipment, and effectively improving overall efficiency.

[0018] Secondly, the automatic feeding mechanism of the device is also excellent. After the detection table is pulled out, the first motor is started to drive the second lead screw to rotate, so that the slider drives the rotating lifting component to move laterally and move the clamping component into the detection table. The sample tray is placed by the electric push rod. During detection, the second motor is started to drive the triangular bracket to rotate and change the position of the clamping component, which facilitates the automatic cyclic loading and unloading of the sample tray. The three clamping components can quickly load and unload the sample tray by circulating. Moreover, the first motor drives the second lead screw to automatically drive the clamping component to move laterally, realizing automatic detection. The automated placement ensures that the sample tray position is uniform, the loading and unloading is convenient and the detection is stable, which greatly improves the overall ease of use of the device.

[0030] Operating principle and advantages: By setting up the lifting mechanism 3, during use, when the third motor 32 is started, the third motor 32 can powerfully drive the second lead screw 33 inside the vertical rail 31 to rotate. As the second lead screw 33 rotates, it can assist in driving the slide 34 to slide smoothly inside the vertical rail 31. By driving the slide 34 to slide inside the vertical rail 31 through the second lead screw 33, the position of the detection stage 5 inside the X-ray fluorescence spectrometer 1 can be flexibly adjusted. The detection stage 5 can move up and down, and can even be completely pulled out from inside the X-ray fluorescence spectrometer 1. This design makes the detection operation more flexible during the overall use of the device, improves the convenience of picking up and putting down samples. More importantly, the entire lifting mechanism 3 is located outside the X-ray fluorescence spectrometer 1. When the lifting mechanism 3 needs to be inspected and maintained, there is no need to laboriously enter the instrument. The inspection and maintenance work can be carried out directly outside the X-ray fluorescence spectrometer 1, which greatly improves the overall convenience of the device and brings great convenience to the use and maintenance of the equipment.

[0031] By setting up an automatic feeding mechanism 2, during use, when the detection stage 5 is pulled out from inside the X-ray fluorescence spectrometer 1, the first motor 212 is started. The first motor 212 drives the first lead screw 213 to rotate. The rotation of the first lead screw 213 can assist in driving the slider 214 to slide smoothly inside the rail frame 211. The sliding of the slider 214 can then assist in driving the lateral displacement of the rotating lifting assembly 22. When the rotating lifting assembly 22 moves laterally, it can drive a clamping assembly 23 to move precisely into the detection stage 5. At this time, by opening the electric push rod 232 of the clamping assembly 23 to pull out the two clamping seats 233, the sample tray 234 inside the clamping seats 233 can be easily placed into the detection stage 5. During this process, by starting the third motor 32, the entire detection stage 5 can be put back into the X-ray fluorescence spectrometer 1 for detection. During the detection process, the second motor 221 is started to drive the support shaft 222 to rotate. The rotation of the support shaft 222 can... The rotation of the triangular support 223 causes the clamping components 23 to rotate laterally, thereby changing their positions. This design facilitates the automatic, reciprocating up-and-down loading and unloading of the sample tray 234, greatly improving the overall ease of use and testing. Furthermore, the cyclical rotation of the three clamping components 23 during testing enables rapid loading and unloading of the sample tray 234, further enhancing the overall ease of use. The first motor 212 drives the first lead screw 213 to rotate, automatically driving the slider 214 to move the clamping components 23 laterally, facilitating the loading and unloading of the sample tray 234 from inside the testing platform 5. This design enables automatic testing, improving the convenience of testing during use. Simultaneously, automated placement ensures that the sample tray 234 is always placed in the same position, making the loading and unloading process convenient and the testing stability strong, greatly improving the overall ease of use of the device.
