When the cartridge case is detected at the bottom, the cartridge case is sucked and fixed in the thumb wheel groove of the feeding thumb wheel 5 through the vacuum suction pipe 51, so that the cartridge case can be prevented from falling down, and the cartridge case is ensured to be detected by the bottom detection camera in a bottom suspension state.
The shell entering the detection disc 7 is clamped by the pressure head device 72 and the bottle rotating seat 71 on the detection disc 7, then the bottle rotating wheel 77 at the bottom of the bottle rotating seat 71 is driven to rotate by the synchronous belt 713, so that the shell rotates along with the movement of the detection disc 7, and 360-degree photographing detection is carried out on the side wall of the shell through the side detection cameras 74 around the detection disc 7.
