[0079] When the detection at the bottle body detection station is completed, the linear transmission module 21 drives the feeding assembly to return to the feeding point, at this time, one of the grabbing assemblies reaches the bottle body detection station, the grabbing clamp 26 of the grabbing assembly clamps the glass bottle 3 at the bottle body detection station, and the nozzle assembly 83 and the bottom film assembly 84 are loosened under the driving of the nozzle motor 81 and the bottom film motor 82, and then the shuttle mechanism 2 moves one station, so that the glass bottle 3 detected by the bottle body detection station moves to the bottle neck detection station. The nozzle motor 81 is started, the front clamping cross beam 87 is driven to move backward, the bottom film motor 82 drives the rear clamping cross beam to move forward, so that the nozzle assembly 83 and the bottom film assembly 84 abut against the bottle mouth and the bottom of the glass bottle 3, at this time, the grabbing clamp 26 of the grabbing assembly at the bottle neck detection station is loosened, the rotating motor 85 at the bottle neck detection station drives the glass bottle 3 to rotate at a set speed by a set angle, and the bottle neck detection camera 71 and the bottle neck detection light source 72 are started, so that a photo of the bottle neck surface of the glass bottle 3 is taken for detection.
