An automatic sorting pearl detection device

Abstract

The invention discloses an automatic sorting pearl detection device, which includes a base. The upper side wall of the base is provided with four support plates, and the upper ends of two of the support plates are jointly connected with a placement box. The upper side wall of the placement box is fixedly connected with a connecting plate. The upper end of the connecting plate is fixedly connected with a cleaning plate. The upper side wall of the cleaning plate is provided with a plurality of through holes. The upper side wall of the cleaning plate is provided with a plurality of openings. There is a pearl, and a push plate is slidingly connected to the upper side wall of the cleaning plate. This invention avoids impurities from affecting the color detection results of pearls by washing the pearls and then detecting them. Through the intermittent engagement of the wedge-shaped block and the wedge-shaped groove, the pearls to be detected are dropped intermittently, and the sequential detection of the pearl colors is completed. Through S9702- The connection between the RGB color sensor and the STM32 microcontroller enables the sorting of good and bad pearls, avoiding manual sorting, improving the work efficiency of pearl sorting, high sorting quality, convenience and practicality, and high promotion.

Description

technical field [0001] The invention relates to the technical field of pearl detection, in particular to an automatic sorting pearl detection device. Background technique [0002] Pearl is an ancient organic gemstone, mainly produced in the molluscs of pearl shellfish and mother-of-pearl shellfish, and the calcium carbonate-containing mineral (aragonite) beads produced by endocrine action are composed of a large number of tiny aragonite crystals. A collection of pearls with magnificent colors and elegant temperament, which symbolizes health, purity, wealth and happiness, has been loved by people since ancient times. It usually requires the same color, and different colors have different qualities. In the prior art, pearls The color separation and screening of pearls are generally cleaned and dried first, and then manually screened, resulting in low efficiency of pearl screening, and human factors are likely to affect the judgment of pearl color quality, thus easily affecting...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of color separation and screening of pearls in the prior art, which is generally first cleaned and dried and then manually screened, resulting in low efficiency of screening pearls, and human factors are likely to affect the judgment of pearl color quality. Thus it is easy to affect the sorting problem of pearls, and a kind of pearl detection device for automatic sorting is proposed
