An adaptive light source adjustment device for jewelry inspection

Abstract

This invention relates to the field of jewelry testing technology, and provides a light source adaptive adjustment device for jewelry testing, including a base and a worktable. A multispectral array light source is arranged above the worktable, and a camera is arranged on one side of the multispectral array light source. The multispectral 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 multispectral array light source, which can switch the lens to a condenser lens or a diffuser lens. A third motor is fixedly installed on the camera, and a polarization mode switching disk is installed on the output shaft of the third motor. The polarization mode switching disk consists of four sets of polarization mode plates, which correspond to no polarization mode, single polarization mode, cross polarization mode, and parallel polarization mode, respectively. Through the coordinated automatic switching of the lens and polarization mode, multi-level and multi-dimensional observation from the surface to the interior is realized, improving the testing efficiency.
