Transfer device and use thereof, and glass bending forming system

Use of a transfer device, wherein the transfer device comprises a suction table, the suction table has a first edge-region and a second edge-region, and the first edge-region surrounds the second edge-region;

• and
• the suction table defines a first suction groove, a plurality of first suction holes, a first suction channel, and a second suction channel, the first suction groove is defined in the first edge-region, the plurality of first suction holes are defined in the second edge-region, the first suction channel is in communication with the first suction groove and is used for providing a first negative pressure, the second suction channel is in communication with the plurality of first suction holes and is used for providing a second negative pressure, and the first negative pressure and the second negative pressure are used for sucking at least one glass sheet on the transfer device, wherein
• the transfer device is configured to transfer a plurality of flat glass sheets onto a bending forming mold for stacking and loading, or configured to transfer a plurality of bent glass sheets subjected to bending forming from the bending forming mold for unloading, or configured to stack a plurality of bent glass sheets subjected to bending forming and simultaneously transfer the plurality of bent glass sheets that are stacked to a loading table of a glass washing machine for cleaning.
