AI Technical Summary

Technical Problem

Existing jewelry testing equipment has fixed light source parameters, making it difficult to adapt to the testing needs of different jewelry materials. It also has a single lighting mode, which cannot take into account multi-level observation of the surface and interior, and its polarization control capability is insufficient.

Method used

Employing a multispectral array light source, it provides ultraviolet light, white light, near-infrared light, and various monochromatic visible light. Each spectral channel is independently controllable. Combined with a lens switching mechanism and a polarization mode switching disk, it achieves automatic adjustment of spectral parameters, lens type, and polarization mode.

Benefits of technology

It achieves adaptive light source adjustment based on jewelry type and testing items, improving testing efficiency and ease of operation, and enabling multi-level and multi-dimensional observation.

Abstract

The invention relates to the technical field of jewelry detection, and provides a light source self-adaptive adjusting device for jewelry detection, which comprises a base and a workbench, a multispectral array light source is arranged above the workbench, and a camera is arranged on one side of the multispectral array light source. The multi-spectral array light source provides ultraviolet light, white light, near-infrared light and various monochromatic visible light, a lens switching mechanism is installed at the output end of the multi-spectral array light source and can switch a lens into a condensing lens or a diffusing lens, a third motor is fixedly installed on the camera, and a fourth motor is fixedly installed on the camera. A polarization mode switching disc is installed on an output shaft of the third motor and composed of four sets of polarization mode plates, and the four sets of polarization mode plates correspond to a non-polarization mode, a single-polarization mode, a cross-polarization mode and a parallel-polarization mode respectively. Through cooperative automatic switching of the lens and the polarization mode, multi-level and multi-dimensional observation from the surface to the interior is realized, and the detection efficiency is improved.
