Abstract

A suction gripping device for picking up a plurality of substrates which are flat and flexible includes: a base body, which defines a plane; at least one gas suction vacuum module which is arranged on the base body and has at least one gas suction opening configured for withdrawing gas by suction and for generating a first vacuum so as to suction a respective one of the plurality of substrates against the suction gripping device; and at least one gas ejection vacuum module which is arranged on the base body and has a gas ejection opening configured for ejecting gas and for generating a second vacuum so as to suction the respective one of the plurality of substrates against the suction gripping device.

First claim

What is claimed is:

1. A suction gripping device for picking up a plurality of substrates which are flat and flexible, the suction gripping device comprising:
a base body, which defines a plane;
at least one gas suction vacuum module which is arranged on the base body and has at least one gas suction opening configured for withdrawing gas by suction and for generating a first vacuum so as to suction a respective one of the plurality of substrates against the suction gripping device; and
at least one gas ejection vacuum module which is arranged on the base body and has a gas ejection opening configured for ejecting gas and for generating a second vacuum so as to suction the respective one of the plurality of substrates against the suction gripping device,
wherein at least one of:
(a) the at least one gas suction vacuum module at least one of (i) forms or includes a Venturi ejector and (ii) includes the following: a gas inlet, a gas outlet, a first connection which runs from the gas inlet to the gas outlet and which has a constriction, and a second connection which branches off between the gas inlet and the gas outlet to the at least one gas suction opening so as to generate the first vacuum by way of a Venturi effect; and
(b) the at least one gas ejection vacuum module at least one of (i) forms or includes a Bernoulli floating suction cup and (ii) includes the following: a gas inlet and a connection from the gas inlet to the gas ejection opening, wherein the gas ejection opening is configured such that an ejected gas runs at an angle to the plane of the base body so as to generate the second vacuum by means of a Bernoulli effect.

2. The suction gripping device according to claim 1 , wherein the at least one gas suction vacuum module includes a contact surface configured for contacting—at least in a plurality of regions of the contact surface—the respective one of the plurality of substrates that is to be picked up by the suction gripping device,
wherein the at least one gas suction opening is formed as a recess within the contact surface, and
wherein the suction gripping device includes a plurality of the at least one gas suction opening each forming a respective one of the recess.

3. The suction gripping device according to claim 2 , wherein at least one of:
(a) the suction gripping device includes a plurality of the at least one gas suction vacuum module;
(b) the suction gripping device includes a plurality of the at least one gas ejection vacuum modules;
(c) the at least one gas suction vacuum module is arranged closer to a center of the plane of the base body than the at least one gas ejection vacuum module; and
(d) the suction gripping device includes a plurality of the at least one gas ejection vacuum module, and the at least one gas suction vacuum module is arranged between the plurality of the at least one gas ejection vacuum module.

4. The suction gripping device according to claim 2 , wherein the suction gripping device includes at least one gas suction vacuum module group and two gas ejection vacuum module groups, the at least one gas suction vacuum module group being arranged in a first direction between the two gas ejection vacuum module groups,
wherein the at least one gas suction vacuum module group includes at least one of the at least one gas suction vacuum module, the contact surface of which extends in a second direction running perpendicular to the first direction, and
wherein each of the two gas ejection vacuum module groups includes a plurality of the at least one gas ejection vacuum module which are arranged side-by-side in the second direction running perpendicular to the first direction.

5. The suction gripping device according to claim 4 , wherein the base body includes opposing edges, the two gas ejection vacuum module groups being arranged at the opposing edges of the base body.

6. The suction gripping device according to claim 2 , wherein the at least one gas suction vacuum module defines a first suction direction, and wherein the at least one gas ejection vacuum module defines a second suction direction which runs at an angle to the first suction direction.

7. The suction gripping device according to claim 2 , wherein the suction gripping device includes at least four of the at least one gas ejection vacuum module, wherein the at least one gas suction vacuum module is arranged both in a first direction and in a second direction running perpendicular to the first direction between the at least four of the at least one gas ejection vacuum module, and wherein the at least one gas suction vacuum module is arranged within a quadrilateral defined by the at least four of the at least one gas ejection vacuum module.

8. The suction gripping device according to claim 2 , wherein at least one of:
(a) the at least one gas suction vacuum module defines a first suction direction and the at least one gas ejection vacuum module defines a second suction direction, wherein the first suction direction and the second suction direction run parallel to one another; and
(b) the at least one gas ejection vacuum module is set back at least one of in the first suction direction, in the second suction direction, perpendicular to the contact surface of the at least one gas suction vacuum module, and perpendicular to the plane of the base body.

9. The suction gripping device according to claim 2 , wherein at least one of:
(a) the at least one gas suction vacuum module and the at least one gas ejection vacuum module each form respectively an independent component;
(b) the suction gripping device includes a distance of at least 1 centimeter between the at least one gas suction vacuum module and the at least one gas ejection vacuum module; and
(c) the at least one gas suction vacuum module and the at least one gas ejection vacuum module are activatable separately.

10. The suction gripping device according to claim 1 , wherein at least one of:
(a) the at least one gas suction vacuum module includes a holding force of at least 12 newtons;
(b) the at least one gas ejection vacuum module includes a holding force of at least 1.8 newtons; and
(c) at least one of (i) the at least one gas suction vacuum module is variably activatable so as to effect at least two different values of the holding force of the at least one gas suction vacuum module, and (ii) the at least one gas ejection vacuum module is variably activatable so as to effect at least two different values of the holding force of the at least one gas ejection vacuum module.

11. The suction gripping device according to claim 1 , wherein the plurality of substrates include at least one of (a) a plurality of thin flexible glass panes and (b) a plurality of thin flexible paper sheets, the plurality of thin flexible glass panes and the plurality of thin flexible paper sheets each including a thickness of less than 100 μm.
