Graded screening device for piezoelectric ceramic pieces

The utility model relates to a classification screening device for piezoelectric ceramic pieces, which comprises a driving piece, a guide piece, a storage piece and a detection piece, and the driving piece comprises a shell, a driving motor and a rotating piece; one end of the guide piece sleeves the rotating piece and is fixedly connected with the shell, and a guide part is further arranged in the guide piece; the storage piece is used for accommodating the piezoelectric ceramic piece; the detection piece is arranged at the tops of the guide piece and the storage piece; the rotating piece can push the piezoelectric ceramic piece to move from the rotating piece to the detection piece along the guide piece for detection; the detection piece is further provided with a push-out part used for pushing the piezoelectric ceramic piece into the guide piece or the storage piece. The detection pieces located on the guide piece and the storage piece are connected in sequence, so that the piezoelectric ceramic pieces can
