Description

Technical Field

[0001] This utility model relates to the field of UV equipment optical path calibration technology, and specifically to a UV equipment optical path calibration reference device. Background Technology

[0002] Ultraviolet (UV) equipment requires optical path calibration during use. A search revealed existing technology (publication number: CN114900585B), which describes "a secondary folding optical path scanner device and calibration method, belonging to the field of scanner technology. This device includes an optical path folding module, which is positioned between the optical lens and the CMOS sensor. This module controls the optical path, splitting a single optical path into multiple segments. The optical path folding module includes a primary folding mirror, a secondary folding mirror, and a folding support. The primary and secondary folding mirrors are mounted on the folding support and are used to fold back the optical path, adjusting the position and orientation of the light incident on the CMOS sensor. This invention utilizes optical path folding to optimize the layout and achieve miniaturization. It allows for free adjustment of the position and orientation of core components, resulting in greater structural variability and improved overall space utilization of the scanner device."

[0003] While existing technologies achieve optical path calibration, the photometric value of the light source needs to be calibrated before optical path calibration. This introduces uncertainties and errors into subsequent optical path calibration. The optical path calibration device described in the aforementioned patent cannot calibrate the light source. Furthermore, existing technologies generally rely on manual operation, specifically using standard solutions of known concentrations for calibration. Each standard solution is sequentially placed into the sample cell, its absorbance is measured, and the measured absorbance value is compared with the theoretical value to calculate the relative error. However, this process is cumbersome and inconvenient for cleaning the sample tubes after use. Utility Model Content

The first clamping cylinder is then rotated to the top of the reagent tube via a rotating plate, clamping it and rotating it to the detection position on the spectrometer. The UV light emitted by the UV device passes through the reagent tube and is received by the detector. The absorbance of the sample is then calculated using a specific algorithm and compared with the absorbance of a known sample.

[0027] Specifically, there are multiple reagent tubes 84, and each reagent tube 84 contains a different sample, including standard substances with known concentrations and specific absorption peaks, such as nitric acid solution, phenol, and iodine.

[0028] It should be noted that reagent tube 84 is made of smooth and transparent quartz material.

[0029] like Figure 1 and Figure 3In the process, the turntable assembly 8 includes a rotating disk 82, and a placement groove 83 is provided at the upper end of the rotating disk 82. The reagent tube 84 is placed in the placement groove 83, and a rotating shaft 81 is connected to the lower end of the rotating disk 82.

[0034] In use, a spectrometer and detector are employed. During the calibration of the ultraviolet (UV) light source, a reagent tube containing a chemical reagent of known absorbance is pre-placed on a rotating disk. A rotating plate rotates the first clamping cylinder to the top of the reagent tube, clamping it and rotating it to the detection position on the spectrometer. The UV light emitted by the UV device passes through the reagent tube and is received by the detector. The absorbance of the sample is calculated using a specific algorithm and compared with the known absorbance of the sample. This comparison determines whether the UV light source's photometric intensity meets the standard, thus confirming the calibration. To ensure the accuracy and exclusivity of subsequent optical path calibration, the built-in optical path foldback module is used to perform calibration and testing of the optical path. Utilizing the column, rotating block, arc block, and fixing plate included in the transfer assembly, the used reagent tube is first clamped by the second cylinder and the second clamping cylinder under the drive of the motor, and then rotated downwards.
