Abstract

An automatic observation apparatus for detecting mineral samples comprises a base ( 1 ), a supporting arm ( 2 ), a sample fixing device ( 3 ), a stepper motor ( 4 ), a high-definition camera ( 5 ) and a control system ( 6 ). A refractometer is fixed on the base ( 1 ). A vertical through hole is formed at the top end of the supporting arm ( 2 ), and a lifting rod ( 211 ) penetrates through the vertical through hole and is matched with the vertical through hole in shape. A cavity is formed at the top end of the supporting arm ( 2 ), a gear ( 216 ) is mounted in the cavity, and the gear ( 216 ) is meshed with a rack ( 215 ) of the lifting rod ( 211 ). The sample fixing device ( 3 ) is a right-hexagonal-prism shell with the top end sealed, a spring ( 312 ) is arranged in a vertical hole of the sample fixing device, a sample locating head fixing device ( 314 ) is arranged at the lower end of the spring ( 312 ), a blind hole is formed in the lower end of the sample locating head fixing device ( 314 ), and a sample locating head ( 316 ) is matched with the blind hole in the lower end of the sample locating head fixing device ( 314 ). The apparatus can conveniently and efficiently fix samples, stray light interference is avoided, mineral samples can be rotated to be observed from different angles, and mineral sample detection accuracy is improved.

First claim
