Abstract
Description
Technical Field
[0001] This utility model relates to the field of spectrometer technology, and in particular to an autofocus Raman spectrometer. Background Technology
[0002] By utilizing optical, mechanical, and electronic control technologies, sensors detect parameters such as the distance between the sample and the instrument or the intensity of the Raman signal. These signals are then fed back to the control system, which drives the focusing device to automatically adjust the position of the optical elements, thereby achieving precise adjustment of the focal length. This allows the laser to be focused on the sample and collect the strongest Raman scattering signal.
[0003] However, in existing technologies, manual focusing in some devices and the difficulty in observing characteristic peaks increase detection time and difficulty. In the quality inspection stage of mass production, this leads to low detection efficiency and the inability to accurately track changes in these substances during the reaction process, making it difficult to determine the reaction rate, reaction mechanism, and reaction conversion rate. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an autofocus Raman spectrometer. This allows for clearer observation of characteristic peaks in the Raman scattering spectrum, facilitating accurate analysis of the molecular structure of samples. It also prevents impurities such as dust and moisture from entering the instrument, avoiding contamination and damage to optical and electronic components, and ensuring the normal operation and lifespan of the instrument.
[0005] To achieve the above objectives, an autofocus Raman spectrometer is provided, comprising a first housing, a fixed block fixedly connected inside the first housing, a drive assembly for power output fixedly connected inside the fixed block, a drive shaft fixedly connected to the output end of the drive assembly, a transmission gear fixedly connected to the outside of the drive shaft, a rotating shaft rotatably connected inside the fixed block, a driven gear fixedly connected to the outside of the rotating shaft, and a tray fixedly connected to the top of the driven gear.
[0006] According to the autofocus Raman spectrometer, the drive assembly includes a motor, the output of which is fixedly connected to the bottom of the drive shaft.
[0007] According to the autofocus Raman spectrometer, the top of the fixed block is fixedly connected to two electric guide rails, and the top of the electric guide rails is slidably connected to a slider.

[0009] According to the autofocus Raman spectrometer, a filter is fixedly connected to the top of the fixed block, and a focusing ring is rotatably connected to the outside of the filter.

[0011] According to the autofocus Raman spectrometer, a spring is sleeved on the outside of the rotating rod, and a second housing is rotatably connected to the outside of the rotating rod.
[0012] According to the autofocus Raman spectrometer, a handle is fixedly connected to the front side of the second housing, and two limiting blocks are fixedly connected to the front side of the second housing. Beneficial effects
[0013] 1. Place the sample on the tray, and drive the drive shaft to rotate the transmission gear under the drive of the motor. The transmission gear drives the driven gear to rotate. The slider is moved by the electric guide rail on the top of the fixed block. A fixed plate is fixed on the top of the slider. There is a laser on the surface of the fixed plate. The laser can be used to illuminate the sample surface on the tray through the filter on the top of the fixed block and the focusing ring outside the filter, which will induce Raman scattering.
