Pearl detection device with automatic sorting function

Abstract

The invention discloses a pearl detection device with an automatic sorting function. The pear detection device comprises a base, wherein four supporting plates are arranged on the upper side wall of the base, the upper ends of two of the four supporting 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, a plurality of through holes are formed in the upper side wall of the cleaning plate, a plurality of pearls are arranged on the upper side wall of the cleaning plate, and the upper side wall of the cleaning plate is connected with a push plate in a sliding mode. According to the pearl detection device, the pearls are washedand then detected, so that the color detection results of the pearls are prevented from being influenced by impurities, intermittent falling of the to-be-detected pearls is realized through intermittent clamping of a wedge-shaped block and a wedge-shaped groove, then sequential detection of the color of the pearls is completed, and sorting between the high-quality pears and the pears with the poorquality is achieved through the connection between an S9702-RGB color sensor and an STM32 microcontroller, so that manual sorting is avoided, the working efficiency of the pearl sorting is improved,the sorting quality is high, convenience and practicability are achieved, and the popularization is high.

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
