System for the handling and confinement of flat objects in individual boxes

System for handling flat objects (10) confined in an ultraclean atmosphere in individual boxes (10) in order to bring the objects (10) into working stations (6, 6A, 6B) where there is a special atmosphere, said system comprising:

• individual boxes (1) in which there is an ultraclean atmosphere, each of said boxes being flat having a concealable door and receiving one of said flat objects;
• means (3) for displacing said boxes (1) in an ordinary atmosphere;
• an interface (5) between the displacement means (3) and an associated one of said working stations (6, 6A, 6B) in which the boxes (1) are opened and the flat objects (10) are extracted from the boxes (1) and kept under a special atmosphere throughout the time which they spend within the working stations (6, 6A, 6B), said interface (5) including a body (11) having an access tunnel, a pick and place robot (12) acting within said access tunnel for passing said objects (10) through said access tunnel, an adapting bottom plate (15) fixed to a first end (16) of the body (11) and to an inlet (17) of the associated one of said working stations (6) to ensure mechanical positioning of the interface (5) relative to the associated one of said working stations (6), and a modular bottom plate (20), said modular bottom plate (20) having means for connecting a feed pipe to a ventilation connection (27) of the boxes (1), and means (25) for opening the boxes (1) to tightly link an interior of said boxes (1) with the body (11);
• and
• a transfer tunnel (4) rigidly connecting two of said working stations (6A, 6B) for transferring said objects (1) between said working stations while keeping said objects under an ultraclean atmosphere.
