Abstract
A device is proposed for the contactless grasping and holding of an object (1) from a direction (z) directed at least partially in the direction (z) of the force of gravity (F), using a holding element (3) situated counter to the direction (z) of the force of gravity (F), at least partially above the object (1) and at a distance from the latter, which to the greatest extent possible avoids the carrying off or migrating of particles that are possibly present. According to the present invention this is achieved in that the holding element (3) is designed as a vibrating holding element (3) for generating levitation waves.
Claims15
A device for the contactless grasping and holding of an object (1, 14) from a direction (z) directed at least partially in the direction (z) of the force of gravity (F), using a holding element (3, 13, 17) situated counter to the direction (z) of the force of gravity (F), at least partially above the object (1, 14) and at a distance from the latter,
- wherein the holding element (3, 13, 17) is designed as a vibrating holding element (3, 13, 17) for generating levitation waves.
The device as recited in one of the preceding claims,
- wherein a support surface (18) of the holding element situated opposite the object (1, 14) is adapted to a surface section of the object (1, 14).
The device as recited in one of the preceding claims,
- wherein an area of the surface section is situated transversely to a vibrational direction (z) of the holding element (3, 13, 17) in this area.
The device as recited in one of the preceding claims,
- wherein the support surface (18) of the holding element (3, 13, 17) has at least one opening (16) of at least one recess (8, 15) of the holding element (3, 13, 17).
The device as recited in one of the preceding claims,
- wherein the recess (8, 15) is designed as a bore (8, 15).
The device as recited in one of the preceding claims,
- wherein at least one additional force generating unit is provided for generating an additional force directed counter to the force of gravity (F).
The device as recited in one of the preceding claims,
- wherein the force generating unit is designed as a pressure generating unit.
The device as recited in one of the preceding claims,
- wherein the pressure generating unit has at least one suction element (8) to draw in the object (1, 14).
The device as recited in one of the preceding claims,
- wherein the pressure generating unit is situated at one end of the recess (8, 15) lying opposite the opening (16).
The device as recited in one of the preceding claims,
- wherein a fixing unit (12, 19) for fixing the object (1, 14) is provided transversely (x, y) to the direction (z) of the force of gravity (F).
The device as recited in one of the preceding claims,
- wherein the fixing unit (12, 19) is designed for the contactless fixing of the object (1, 14).
The device as recited in one of the preceding claims,
- wherein a vibrating fixing element (19) of the fixing unit (12, 19) is provided for generating levitation waves.
The device as recited in one of the preceding claims,
- wherein a plurality of holding elements (3, 13, 17) and/or fixing elements (12, 19) is provided.
A method for the contactless grasping and holding of an object (1, 14) from a direction (z) directed at least partially in the direction (z) of the force of gravity (F), using at least one holding element (3, 13, 17) situated counter to the direction (z) of the force of gravity (F), at least partially above the object (1, 14) and at a distance from the latter,
- wherein a device as recited in one of the preceding claims is used, having a vibrating holding element (3, 13, 17) for generating levitation waves.
