Vacuum adsorption control mechanism device, film pasting device, method of pasting film, and display device

A vacuum suction control mechanism comprising:

• a first member comprised of a cylindrical bonding head (3) for attracting a film (17) free of the use of air blow, the first member comprising a curved shape surface along which the film (17) is attracted, an end face (3a), and a plurality of suction holes (9a) which attract the film, the suction holes extending through from the end face to the curved shape surface, the plurality of suction holes being connectable to a single decompression source, the suction holes each comprising a porous sheet (23) provided within the suction hole along the curved shape surface;
• a second member comprised of a base member (5) directly on—the end face (3a) of the bonding head (3) adjacent and facing the end face (3a) of the bonding head (3), the base member including a groove (11) provided on a surface facing the bonding head (3), the second member arranged for contacting the plurality of suction holes by the second member being movable relative to the first member, the base member (5) comprising a hole (13) extending through the base member (5) from the groove (11) to a surface of the base member (5) opposite to the surface facing the bonding head (3), the hole (13) being connected to the decompression source;
• a shaft (7) provided at a center of axes of the bonding head (3) and the base member (5), where the bonding head (3) is rotatable about the shaft (7);
• and
• a bonding surface plate (15);
• wherein the groove comprises a shape corresponding to the curved shape of the first member, the groove selectively connecting some of the suction holes to the decompression source, where the number of the connected suction holes corresponds to a relative position between the first member and the second member, the groove of the second member being moved relative to the first member so that the suction holes that communicate with the groove are connected to the decompression source, and
• wherein the first and second member can be moved in the direction of the curved shape and with respect to the film.
