The present application describes a system for attaching stoppers by vacuum, for artificial visual inspection, falling within the field of machines for electronically selecting cork stoppers and derivatives thereof. Said system comprises a vacuum generator (4) which is connected to a central drive shaft (1) of a rotational mechanical structure. Said drive shaft transmits the generated vacuum via an interior channel (2) to the upper end thereof, where it comes into contact with a stopper (3), enabling, by means of a suction effect, attachment thereof. Furthermore, the drive shaft (1) rotates, which, in turn, transmits the same movement to the stopper (3), which enables the entire body thereof to be analysed by means of an artificial viewing system. Said system can be used for inspecting cork stoppers and derivatives thereof.
