Abstract

A laying die, for picking up and laying of substrates, comprising an elastically deformable substrate receiving structure providing an engagement surface for releasable receiving of substrates, an attaching element comprising a gas channel for providing positively or negatively pressurized gas for picking up and blowing off the substrates, and a carrier body made from elastically deformable material and sandwiched between the substrate receiving structure and the attaching element which is arranged to distribute the positively or negatively pressurized gas over the carrier body. The carrier body comprises breakthroughs to transfer the pressurized gas from the attaching element to the substrate receiving structure that comprises an elastically deformable distribution plate to distribute the positively or negatively pressurized gas over the engagement surface. Also, a laying device which changes the position and/or orientation of substrates to predetermined values can comprise the laying die and a method for manufacturing the laying die.

First claim

The invention claimed is:

1. A laying die for picking up and laying of substrates, the laying die comprising:
an elastically deformable substrate receiving structure configured to provide an engagement surface to releasably receive substrates;
an attaching element comprising a gas channel configured to provide positively or negatively pressurized gas to pick up and blow off the substrates;
a carrier body made from an elastically deformable material, the carrier body being sandwiched between the substrate receiving structure and the attaching element, the attaching element being arranged to distribute the positively or negatively pressurized gas over the carrier body, and the carrier body comprising a plurality of breakthroughs to transfer the positively or negatively pressurized gas from the attaching element to the substrate receiving structure, and the substrate receiving structure comprising an elastically deformable distribution plate to distribute the positively or negatively pressurized gas over the engagement surface of the substrate receiving structure; and
a cambering device configured to deform at least one of the carrier body and the substrate receiving structure according to a predetermined deformation after the substrates are picked up by the laying die, the cambering device comprising a rope attached to the substrate receiving structure, and configured to pull the at least one of the carrier body and the substrate receiving structure into the predetermined deformation.

2. The laying die according to claim 1 , wherein
the breakthroughs are evenly distributed over a longitudinal extension direction of the carrier body, and are formed as slits extending perpendicular to the longitudinal extension direction of the carrier body.

3. The laying die according to claim 1 , wherein the breakthroughs are formed as circles arranged in a matrix with more than two rows and two columns.

4. The laying die according to claim 1 , wherein
wall surfaces of at least one of the breakthroughs and the carrier body surfaces at least partially comprise air-tight seals formed with a glue, or a silicon film glued to or a thermoplastic film melted to at least one of the wall surfaces and the carrier body surfaces.

5. The laying die according to claim 1 , wherein the distribution plate comprises
an elastically deformable film which comprises evenly distributed holes; and
a heating element.

6. The laying die according to claim 1 ,
wherein
the distribution plate comprises a sandwich structure of two stacked elastically deformable films with correspondingly arranged holes, and the heating element is arranged in between the two films ( 40 , 41 ).

7. The laying die according to claim 1 , wherein
the rope is arranged in the breakthroughs of the carrier body, the breakthroughs of the carrier body being adapted to concentrate a negative pressure in the area of lateral edges of the carrier body.

8. The laying device for picking-up and laying of the substrates according to at least one of predefined positions and orientations, the laying device comprising a laying die according to claim 1 .

9. The laying device according to claim 8 , comprising
a robot arm configured to at least one of
move the laying die in a plurality of spatial directions;
rotate the laying die around an axis intersecting an upper surface of the attaching element; and
pivot the laying die around an axis parallel to the upper surface of the attaching element.

10. The laying device according to claim 8 , further comprising
a control device configured to control at least one of movement, rotation and pivoting of the laying die, the control device comprising a storage device configured to store predetermined values of at least one of the position and orientation of the substrates, and an activation device configured to activate at least one of movement, rotation and pivoting of the laying die.

11. The laying device according to claim 10 , wherein the control device is configured to control the cambering device based on predetermined cambering values stored in the storage device.

12. The laying die according to claim 2 , wherein
wall surfaces of at least one of the breakthroughs and the carrier body surfaces at least partially comprise air-tight seals formed with a glue, or a silicon film glued to or a thermoplastic film melted to at least one of the wall surfaces and the carrier body surfaces.

13. The laying die according to claim 3 , wherein
wall surfaces of at least one of the breakthroughs and the carrier body surfaces at least partially comprise air-tight seals formed with a glue, or a silicon film glued to or a thermoplastic film melted to at least one of the wall surfaces and the carrier body surfaces.
