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

摘要

An object of the present invention is to provide a vacuum suction control mechanism apparatus capable of accurately bonding a film to a bonding object with a simple structure. A vacuum suction control mechanism apparatus according to the present invention includes a first member including a plurality of suction holes formed in a surface thereof, the plurality of suction holes being connectable to a decompression source, and a second member capable of contacting the plurality of suction holes, the second member being movable relative to the first member, wherein the second member includes connecting member connecting some of the suction holes, the number of which corresponds to a relative position between the first member and the second member, to the decompression source.

1. A vacuum suction control mechanism comprising:
a first member comprising a curved shape surface, an end face, and a plurality of suction holes which attract a film, the suction holes extending through from the end face to the curved shape surface, the plurality of suction holes being connectable to one decompression source; and a second member provided directly on the end face of the first member capable of contacting the plurality of suction holes which comprise pieces formed of a porous sheet provided within the suction holes, the second member being movable relative to the first member, wherein the second member includes a groove facing the end face of the first member, the groove comprising a shape corresponding to the curved shape, connecting some of the suction holes, the number of which suction holes corresponds to a relative position between the first member and the second member, to the decompression source via a hole extending through the second member from the groove to an exterior of the second member, the hole extending through the second member from the groove to an exterior of the second member being connected to the decompression source, wherein the groove of the second member is movable relative to the first member so that the suction holes that communicate with the groove are connected to the decompression source, wherein the first and second member can be moved in the direction of the curved shape and with respect to the film, and wherein air blow is not used for attracting the film.
