Description

Technical Field

[0001] This utility model relates to the field of spectrometer technology, and in particular to a darkroom device for spectrometer data acquisition. Background Technology

[0002] A spectrometer is a precision instrument that analyzes the composition, structure, and properties of substances by measuring the wavelength distribution of electromagnetic radiation. It decomposes composite light into monochromatic light and quantifies the intensity of each wavelength. It is widely used in chemical analysis, environmental monitoring, astronomy, biomedicine, and other fields. In the field of spectral analysis, the actual acquisition process of a spectrometer usually needs to be carried out in a dark room environment. The light path is physically blocked by a light shield to ensure that the beam can be collimated to the sample to be tested. Existing spectral acquisition devices have a certain light shielding capability, but the adjustment process of the light shield is cumbersome, the light shielding matching efficiency is low, and it is difficult to meet the diverse testing needs of samples of different sizes and properties.

[0003] To address the aforementioned issues, a darkroom device for spectrometer data acquisition has been developed. Utility Model Content

[0004] In order to overcome the shortcomings of existing spectral acquisition devices, such as cumbersome light-blocking plate adjustment process, low light-blocking matching efficiency, and difficulty in meeting the diverse testing needs of samples of different sizes and properties, this utility model provides a darkroom device for spectrometer acquisition.

[0005] The technical solution of this utility model is as follows:

[0006] A darkroom device for spectrometer data acquisition includes a data acquisition box, a light-shielding cover rotatably connected to the upper left side of the data acquisition box, a light-receiving port on the right side of the data acquisition box, a refractor connected to the upper inner right side of the data acquisition box, a grating rotatably connected to the right inner side of the data acquisition box, a dimming component on the right side of the data acquisition box capable of adjusting the reflection angle of the grating, a receiving module connected to the left side of the data acquisition box, a display screen connected to the upper right side of the data acquisition box, a placement base connected to the bottom left side of the data acquisition box, and a light-blocking component installed on the data acquisition box.

[0007] Preferably, the light-blocking assembly includes two guide rails. The guide rails are connected to both the front and rear sides of the center of the acquisition box. A first light-blocking plate is slidably connected to the rear guide rail. A second light-blocking plate is slidably connected between the two guide rails. The first light-blocking plate is located above the second light-blocking plate. A rack is connected to the front of both the first and second light-blocking plates. A worm gear is rotatably connected to the front of the acquisition box. A transmission rod is rotatably connected to the front of the acquisition box. A worm wheel is connected to the middle of the transmission rod and meshes with the worm gear. A gear is connected to the right side of the transmission rod and meshes with the adjacent rack.

[0008] Preferably, the device also includes a support assembly, which includes a support member. The support member is snapped onto the placement seat. The support member has a limiting hole in the middle and protrusions are connected to both the front and rear parts of the support member.

[0009] Preferably, the light-shielding cover also includes a sealing strip, which is attached to the light-shielding cover.

[0010] Preferably, the light-shielding cover is provided with an assist groove.

[0011] Preferably, the worm gear is provided with anti-slip texture.

[0012] By adopting the above technical solution, this utility model has the following advantages:

[0013] This invention utilizes a light-blocking assembly, where a worm gear drives a worm wheel to rotate, which in turn drives a transmission rod and gears to rotate. This causes the first and second light-blocking plates to move in opposite directions along the guide rail, thereby adjusting the first and second light-blocking plates to a suitable position to match the testing requirements of samples with different properties and sizes.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] A darkroom device for spectrometer data acquisition, such as Figure 1 and Figure 2 As shown, the system includes a data acquisition box 1, a light shield 2 rotatably connected to the upper left side of the data acquisition box 1, an assist groove on the light shield 2, a light inlet 3 on the right side of the data acquisition box 1, a refractor 4 connected to the upper inner right side of the data acquisition box 1, a grating 5 rotatably connected to the right inner side of the data acquisition box 1, a dimming component on the right side of the data acquisition box 1 that can adjust the reflection angle of the grating 5, a receiving module 7 connected to the left inner side of the data acquisition box 1, a display screen 8 connected to the upper right side of the data acquisition box 1, a sealing strip 9 connected to the light shield 2, a placement seat 10 connected to the bottom left inner side of the data acquisition box 1, and a light blocking component 11 installed on the data acquisition box 1.

[0021] like Figures 1-3 As shown, the light-blocking assembly 11 includes two guide rails 117. The guide rails 117 are connected to both the front and rear sides of the center of the acquisition box 1. A first light-blocking plate 111 is slidably connected to the rear guide rail 117. A second light-blocking plate 112 is slidably connected between the two guide rails 117. The first light-blocking plate 111 is located above the second light-blocking plate 112. A rack is connected to the front of both the first light-blocking plate 111 and the second light-blocking plate 112. A worm gear 113 is rotatably connected to the front of the acquisition box 1. The worm gear 113 has anti-slip textures. A transmission rod 115 is rotatably connected to the front of the acquisition box 1. A worm wheel 114 is connected to the middle of the transmission rod 115. The worm wheel 114 meshes with the worm gear 113. A gear 116 is connected to the right side of the transmission rod 115. The gear 116 meshes with the adjacent rack.

[0022] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes a support assembly 12, which includes a support member 121. The support member 121 is snapped onto the placement seat 10. A limiting hole 122 is opened in the middle of the support member 121. Both the front and rear parts of the support member 121 are connected to protrusions 123.

[0023] It should be noted that a spectrometer is a precision instrument that analyzes the composition, structure, and properties of substances by measuring the wavelength distribution of electromagnetic radiation. It decomposes composite light into monochromatic light and quantifies the intensity of each wavelength. It is widely used in chemical analysis, environmental monitoring, astronomy, biomedicine, and other fields. When using a spectrometer for data acquisition and analysis, firstly, the light-shielding cover 2 is flipped upwards using the assist groove on the light-shielding cover 2. Then, the sample to be tested is placed on the support component 12 of the placement base 10. The limiting hole 122 can assist in positioning the sample to be tested. Subsequently, the light-shielding cover 2 is closed, and the sealing strip 9 is deformed under pressure, so that a light-closed environment is formed inside the acquisition box 1. Then, the worm gear 113 is rotated, driving the worm wheel 114 to rotate, which in turn drives the transmission rod 115 and the gear 116 to rotate, so that the first light-blocking plate 111 and the second light-blocking plate 111 are aligned. Plate 112 moves in opposite directions along guide rail 117, thereby adjusting the first light-blocking plate 111 and the second light-blocking plate 112 to the appropriate positions. Then, the external light source is introduced through the light port 3, and the light is reflected by the refracting mirror 4 onto the grating 5. At this time, the tilt angle of the grating 5 is adjusted by adjusting component 6 so that the incident light is projected onto the surface of the grating 5 at the optimal angle. The grating 5 disperses the composite light into a continuous spectrum, which is then projected onto the sample to be tested through the gap between the first light-blocking plate 111 and the second light-blocking plate 112. The first light-blocking plate 111 and the second light-blocking plate 112 can block non-target light paths and block stray light reflected and scattered inside the instrument, ensuring that the beam is collimated and enters the receiving module 7. Then, the receiving module 7 transmits the spectral data to the display screen 8 after processing by FPGA, thereby intuitively understanding the properties of the sample.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
