The invention discloses a gripping and transferring device for a flexible porous thin sheet. The device comprises a non-contact type suction cup adsorption mechanism and a charging/discharging line, wherein one end of the non-contact type suction cup adsorption mechanism is fixed on the charging/discharging line by a fixed support; the other end of the non-contact type suction cup adsorption mechanism also comprises a lifting driving air cylinder and an adsorption mechanism which is positioned below the lifting driving air cylinder; and the adsorption mechanism consists of a plurality of suction cups. The device disclosed by the invention adsorbs by adopting the non-contact type suction cup adsorption mechanism, and the suction cups do not contact the sheet, so that the damage to the flexible porous thin sheet is avoided; the flexible thin sheet with pores also can be adsorbed, and the non-contact type suction cup adsorption mechanism adsorbs by generally and straightly adopting compressed air without a vacuum generator, so that the smoothness of the flexible porous thin sheet in processes of gripping, transferring and placing can be guaranteed. The device has a compact and reasonable overall layout; moreover, the technique is mature and the equipment cost is low.
