Description

Technical Field

[0001] This utility model relates to the field of analytical equipment technology, and in particular to a high-precision hyperspectral testing and analysis device. Background Technology

[0002] Hyperspectral analysis equipment is an advanced optical instrument used to acquire and analyze the spectral information of objects at different wavelengths. This equipment can provide high-precision, high-resolution spectral data and is widely used in materials science, environmental monitoring, food safety, medical diagnostics, and many other fields.

[0003] Hyperspectral testing and analysis equipment is a powerful and widely used optical instrument. It provides high-precision, high-resolution spectral data, helping researchers and engineers better understand the properties and behavior of substances. According to the authorized publication number "CN217180582U", a high-precision hyperspectral testing and analysis equipment is disclosed, including a main body and a handle. A test head is located at one end of the main body, and a mounting plate is fixedly installed on the top of the main body. A mounting connector is movably connected to one side of the top of the mounting plate via a hinge. A second connecting end is fixed to the bottom of the main body. The handle is located below the main body, and a second threaded connector is fixed to the top of the handle. The beneficial effects of this invention are: the handle and the main body are threadedly connected via the second threaded connector and the second connecting end. When the equipment is not in use, the handle is removed and threaded onto the mounting connector. The handle then rests in a slot on the mounting plate, reducing the equipment's size and making it easier to carry and store.

[0004] Currently, hyperspectral testing and analysis, after ensuring that light can be emitted normally, separates different light into different wavelengths so that they can illuminate objects. Then, the detector senses the light. However, most detection instruments cannot be adjusted in position during testing. Moreover, even if the position needs to be adjusted, it requires manual and repeated installation, disassembly, and repositioning, which is relatively cumbersome. Furthermore, if the distance of the detector is not adjusted, it will directly affect the spectral resolution. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a high-precision hyperspectral testing and analysis device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-precision hyperspectral testing and analysis device, including a base, a support sleeve fixedly installed on one side of the base by a bracket, a lamp holder fixedly installed through the inside of the support sleeve, and a lamp head installed at the end of the lamp holder with power connected to it; A support frame is fixedly mounted on the upper end of the base near the support sleeve.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example 1 Reference Figures 1-4 A high-precision hyperspectral testing and analysis device includes a base 1. A support sleeve 11 is fixedly installed on one side of the base 1 via a bracket. A lamp holder 12 is fixedly installed through the inside of the support sleeve 11. A lamp head 13 is installed at the end of the lamp holder 12 and powered on. The lamp head 13, together with the lamp holder 12, can serve as a light source to provide stable light covering a wide wavelength range. Common light sources include xenon lamps, halogen lamps, and LED light sources. These light sources can emit continuous spectra covering the wavelength range from ultraviolet to near-infrared. A support frame 14 is fixedly mounted on the upper end of the base 1 near the support sleeve 11. The support frame 14 has an L-shaped structure. A triangular prism 15 is fixedly mounted on the upper end of the support frame 14. One side of the triangular prism 15 covers the light source position of the lamp head 13. The triangular prism 15 can be used as a beam splitter to split the light emitted by the light source into different wavelengths. A positioning seat 16 is fixedly installed at the end of the base 1 away from the support sleeve 11. A positioning shaft 17 is fixedly sleeved on the positioning seat 16. A platform 18 is fixedly installed on the upper end of the positioning shaft 17. Cylinders 19 are fixedly installed on both sides of the platform 18 through brackets. A piston rod for extension and retraction is provided inside the cylinder 19. A clamping plate 110 is fixedly installed at the end of the piston rod. The test object can be placed on the platform 18. By extending and retracting the piston rod of the cylinder 19, the object can be clamped and positioned in conjunction with the clamping plate 110.

[0018] It should be further explained that a bearing 2 is provided on the surface of the positioning shaft 17. The inner ring wall of the bearing 2 is interference-fitted with the surface of the positioning shaft 17. A disc 21 is fixedly sleeved on the outer ring wall of the bearing 2. The disc 21 can rotate on the positioning shaft 17 based on the bearing 2, thereby adjusting the circumferential position of the detector 37 and better receiving reflected or transmitted light.

[0019] It should be further explained that a motor 22 is fixedly installed on the top of the base 1 by a bracket. The motor 22 has a drive shaft inside, and a drive gear 23 is fixedly installed at the end of the drive shaft. When the motor 22 is connected to the power supply, the drive shaft can be driven, thereby driving the drive gear 23 to rotate stably.

[0020] It should be further explained that a number of teeth 24 are fixedly distributed on the outer ring wall of the disk 21. The edge of the drive gear 23 is meshed with the teeth 24. Through the meshing transmission of the linkage gear structure formed by the drive gear 23 and the teeth 24, the rotation stability of the disk 21 can be guaranteed.

[0021] It should be further explained that a bearing seat 3 is fixed to the lower part of the disc 21 near the bearing 2 by a bracket. A threaded rod 31 is rotatably installed inside the bearing seat 3. A motor 32 is installed at the other end of the threaded rod 31. The outer wall of the motor 32 is fixed to the lower end face of the disc 21 by a bracket. A rotating shaft 2 for driving is installed inside the motor 32. The end of the rotating shaft 2 is fixed to the surface of the threaded rod 31 by a coupling. A forward and reverse switch, model HY2-8, is connected to the motor 32 by wires. The forward and reverse switch can operate the motor 32 in both directions, thereby driving the rotating shaft 2 in both directions and driving the threaded rod 31 to rotate in both directions. Finally, the threaded sleeve 33 moves in both directions.

[0022] It should be further explained that a threaded sleeve 33 is threadedly installed on the surface of the threaded rod 31, and a limiting block 34 is fixedly installed on the surface of the threaded sleeve 33. A limiting hole 35 is opened on the surface of the disc 21, penetrating its interior. The two sides of the limiting block 34 are slidably and tightly attached to the inner wall of the limiting hole 35. By sliding the limiting block 34 in the limiting hole 35, the threaded sleeve 33 can be driven, allowing the limiting block 34 to move horizontally in the back-and-forth direction.

[0023] It should be further explained that a substrate 38 is fixedly installed on the upper end of the limiting block 34. Several detectors 37 are fixedly installed on the side of the substrate 38 near the stage 18. The side of the substrate 38 away from the detectors 37 is fixedly installed to the surface of the limiting block 34 through reinforcing ribs 36. The detectors receive the split light signal and convert it into an electrical signal. Common detectors 37 include CCD (charge-coupled device) and CMOS (complementary metal-oxide-semiconductor). The detectors 37 have high sensitivity and low noise, and can accurately capture light signals. The sensing distance of the detectors 37 can be adjusted, making them more flexible and facilitating calibration work in the testing process.

[0024] In practice This scheme utilizes the spectral dispersion characteristics of a prism 15 to decompose composite light into monochromatic light. When the lamp head 13 (such as a xenon lamp or halogen lamp) emits a continuous spectrum with a wide wavelength range, the light passes through the prism 15. Due to the different refractive indices of different wavelengths of light in the glass medium, dispersion occurs. Short-wavelength light (such as ultraviolet light) has a larger refraction angle, while long-wavelength light (such as near-infrared light) has a smaller refraction angle, thus separating the incident light into continuous spectral bands. The dispersed light can then illuminate the surface of the sample on the stage 18. Some of the light is absorbed by the sample, while the rest is reflected or transmitted. The detector 37 (such as a CCD or CMOS) receives these reflected / transmitted light signals, converts them into electrical signals, and then analyzes the spectral characteristics of the sample. This process ensures high spectral resolution and is suitable for the accurate detection of material components. The second key principle of the device is to achieve multi-dimensional dynamic scanning of the detector 37 through a motor drive system. First, motor 22 drives the drive gear 23 to rotate. Through the meshing transmission with the outer ring teeth 24 of the disk 21, the disk 21 is driven to rotate horizontally around the positioning shaft 17, thereby adjusting the circumferential position of the detector 37. Second, motor 32 converts the rotational motion into the linear motion of the limiting block 34 through the cooperation of the threaded rod 31 and the threaded sleeve 33. Since the limiting block 34 is limited by the guiding effect of the limiting hole 35, the threaded sleeve 33 drives the substrate 38 and the detector 37 to move radially. The coordinated work of the two enables the detector 37 to be accurately positioned in a two-dimensional plane, covering the reflected or transmitted light signals of different areas of the sample. This dynamic scanning mechanism improves the flexibility of the test and the efficiency of data acquisition, and is especially suitable for multi-point analysis of non-uniform samples.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
