Description

Technical Field

[0001] This utility model belongs to the field of laser calibration technology for Fourier transform infrared spectrometers, specifically, it relates to a laser calibration platform. Background Technology

[0002] In the pharmaceutical field, especially in particle size analysis of drugs, laser diffraction is widely used due to its advantages such as wide applicability, broad measurement range, high accuracy, good reproducibility, simple operation, and rapid testing. A high-performance laser particle size analyzer is fundamental to obtaining stable and reliable particle size detection results, while the accuracy of the laser calibration platform directly affects the measurement accuracy of the laser particle size analyzer.

[0003] Utility model CN222337053U relates to the field of laser calibration technology for Fourier transform infrared spectrometers, and discloses a laser calibration platform for Fourier transform infrared spectrometers. The platform includes a base plate, a laser calibration movable plate located above the top of the base plate, and a cross-shaped center plate located above the top of the laser calibration movable plate. The laser calibration movable plate includes multiple sets of up-and-down adjusting screws at both ends and a laser plate located above the top of the laser calibration movable plate. This utility model records the image of the laser source on a transparent sheet using a camera and transmits it to a computer. Observing the image on the transparent sheet does not require a handheld infrared observation mirror, reducing labor costs to a certain extent. The use of planar adjusting screws to move the laser module improves motion accuracy and allows for rapid alignment of the laser source image on the transparent sheet with the center cross of the transparent sheet, thus improving efficiency and making laser calibration more efficient.

The following embodiments are used to illustrate this utility model.

[0031] Example 1: A laser calibration platform, specifically as follows Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the system includes a laser detection box 10, which is placed on a table.

The position of the medicine is limited by the limiting structure. The medicine is placed on the top of the light-transmitting plate 25. The first electric push rod 27 is activated, which drives the slider 28 to move inside the protective frame plate 26. The medicine is clamped and fixed by two sets of limiting plates 29. The protective cover plate 22 is placed on the top of the adjusting plate 19, so that the first magnetic strip 21 and the second magnetic strip 24 are magnetically connected.

[0032] Specifically, such as Figure 1 , Figure 3 and Figure 4As shown, the first limiting part also includes two sets of first electrical control boxes 30 fixedly installed on the top of the adjusting plate 19. Each set of first electrical control boxes 30 is electrically connected to two sets of first electric push rods 27. The first electric push rods 27 are powered and controlled through the first electrical control boxes 30.

[0033] Based on the above, the structure of the laser detection box 10, adjustment plate 19, protective cover plate 22, transparent light plate 23, second magnetic strip 24, light-transmitting plate 25, protective frame plate 26, first electric push rod 27, slider 28, limiting plate 29 and first electric control box 30 achieves the purpose of limiting and fixing the medicine, solving the problem of medicine position deviation, improving the effect of medicine scanning and detection, and improving the stability of the device.

[0034] Example 2: Based on Example 1, specifically as follows... Figure 1 , Figure 3 and Figure 4 As shown, four sets of support columns 17 are fixedly installed inside the laser detection box 10. Seven sets of first limit holes 18 are opened inside the support columns 17. Four sets of holes are opened at the bottom of the adjustment plate 19.

[0038] Example 3: Based on Examples 1 and 2, specifically as follows... Figure 1 , Figure 3 and Figure 4 As shown, two sets of second electric push rods 31 are provided on the top of the adjusting plate 19, and two sets of second electric control boxes 32 are fixedly installed on the top of the laser detection box 10. The two sets of second electric control boxes 32 are electrically connected to the two sets of second electric push rods 31 respectively. When the second electric control box 32 is started, it drives the second electric push rods 31 to move, which in turn drives the adjusting plate 19 to move up and down, thus adjusting the height of the adjusting plate 19.

[0039] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, a laser control box 33 is fixedly installed on the top of the laser detection box 10. A laser device is installed on the top inner side of the laser detection box 10. The laser control box 33 is electrically connected to the laser device. A reflector 36 is fixedly installed on the bottom inner side of the laser detection box 10. A third electrical control box 37 is fixedly installed on the bottom of the laser detection box 10. A wire 38 is fixedly installed at one end of the third electrical control box 37 and is connected to an external power supply. The third electrical control box 37 is electrically connected to the reflector 36. When the laser control box 33 is started, the laser device is controlled and used. Power is supplied to the reflector 36 through the third electrical control box 37 and the wire 38, and the reflector 36 reflects light onto the adjustment plate 19.

[0040] In summary, the structure of the laser detection box 10, the second electric push rod 31, the second electric control box 32, the laser control box 33, the snap-fit ​​block 34, the reflector 36, the third electric control box 37, and the wires 38 achieves the purpose of powering and driving the device, thereby improving the detection efficiency of medicines and optimizing the user experience of the device.

[0041] Working principle: When the test drug needs to be calibrated, the drug is first placed on top of the light-transmitting plate 25. The first electrical control box 30 is activated to power and control the first electric push rod 27. After receiving a signal, the first electric push rod 27 drives the slider 28 to move inside the protective frame plate 26. As the slider 28 moves, the two sets of limiting plates 29 gradually approach and clamp and fix the drug, thus ensuring that the drug will not shift during the test. The protective cover plate 22 is placed on top of the adjusting plate 19 and is firmly fixed to the adjusting plate 19 through the magnetic connection of the first magnetic strip 21 and the second magnetic strip 24. In this way, the protective cover plate 22 not only blocks the top of the light-transmitting plate 25 to prevent external light interference, but also further ensures the stability of the drug. In some cases, it may be necessary to adjust the height of the adjusting plate 19 according to the size of the drug or the test requirements. The second electrical control box 32 can be activated to power and control the second electric push rod 31. After receiving a signal, the second electric push rod 31 will drive the adjusting plate 19 to move up and down, which can easily adjust the height of the adjusting plate 19 to meet the detection requirements of drugs of different sizes. After the height of the limiting structure and the adjusting plate 19 are adjusted, the laser control box 33 can be started to control the laser equipment. The laser equipment will emit laser beams, which will irradiate the light-transmitting plate 25 on the adjusting plate 19 and the drug. After penetrating the drug, the laser beams will be reflected back by the reflector 36. The reflector 36 is connected to an external power supply through the third electric control box 37 and the wire 38 to ensure that it can work normally. The reflected laser beams will be captured by the receiver inside the laser detection box 10 and converted into electrical signals for processing and analysis. By analyzing these electrical signals, key information such as the particle size distribution of the drug can be obtained. In order to ensure the accuracy and stability of the detection, the laser detection box 10 is also equipped with components such as a sealing plate 14 and a protective plate 12. The sealing plate 14 is installed inside the first locking slot 11 by the first locking plate 15 and can be easily opened and closed by the handle 16. This ensures the laser inspection box 10 remains sealed when not in use, preventing external interference. The protective plate 12 is located on the front of the laser inspection box 10 to protect the internal laser equipment and inspection components from external damage.
