Abstract

The invention relates to the technical field of Raman spectrometers, and discloses an automatic focusing mechanism of a Raman spectrometer, which comprises a motor bracket, a direct-current gear motor, a transmission gear rotating shaft bracket, a transmission gear, a coded disc gear, a probe, a reset detection photoelectric switch and a hole site detection photoelectric switch. According to the invention, the direct-current gear motor drives the gear transmission to realize rapid and automatic focusing of the probe; the photoelectric switch realizes accurate multi-stage positioning of the probe by detecting a positioning hole in a coded disc gear; the position of the probe is effectively limited by the selective rotation feeding groove on the motor bracket, so that the positioning is stable, and the problems that the focus of the Raman spectrometer cannot be adjusted according to different conditions and the proper position of a sample and the laser focus of the Raman spectrometer cannot be ensured in the prior art are effectively solved.

Description

technical field [0001] The invention relates to the technical field of Raman spectrometers, in particular to an automatic focusing mechanism of Raman spectrometers. Background technique [0002] In recent years, with the maturity of surface-enhanced Raman technology, Raman detection technology has been applied to more and more scenarios, especially in the fields of food detection, explosive detection, and drug raw and auxiliary materials detection. Raman detection equipment can quickly detect illegal additives, pesticide residues and veterinary drug residues in food and other illegal ingredients. As a fast detection instrument, the Raman spectrometer is more portable and can be more conveniently applied to various usage scenarios. When using the existing Raman spectrometer, it is necessary to align the sample and ensure that the sample and the laser focus of the Raman spectrometer are in a suitable position. If the sample cannot be well aligned with the Raman laser, the det...
