20090014283 | DEVICE FOR NON-CONTACT CONVEYING, HANDLING AND STORAGE OF STRUCTURAL ELEMENTS AND MATERIALS - A device for generating a floating state of an object by sound waves includes a rigid support structure having a top surface for absorbing forces generated by the gravitation or acceleration of the levitating object and perpendicularly acting on the top surface. A thin oscillatory element is arranged in parallel to the top surface. Further provided is a vibration generator for making the thin oscillatory element vibrating and levitating above the top surface so that the object is levitating above the thin oscillatory element without contacting it. | 01-15-2009 |
20110311320 | DEVICE FOR NON-CONTACT TRANSPORTING AND HOLDING OF OBJECTS OR MATERIAL - The present invention relates to a device for transporting and holding of touch-sensitive structural elements or materials, the device comprising the following features: At least an oscillatory plate-like take-up | 12-22-2011 |
20120274011 | VACUUM-GRIPPER - The present invention relates to a vacuum gripper and in particular to a vacuum gripper for gently gripping work-pieces having sensitive surfaces, such as solar cells, wafers, or panels for flat screens, and for gripping heavy glass plates or plates made of other material having a very smooth surface that are stacked on top of each other and should be removed from above, wherein the vacuum gripper has the following characteristics: a straight or curved gripper plate ( | 11-01-2012 |
20120327402 | INSPECTION DEVICE - The invention relates to a device for inspecting contact-sensitive planar materials or workpieces, e.g. wafers for the semiconductor industry, solar cells, glasses, FPD substrates, or biologically active substrates for biosensors, as well as materials having contact-sensitive curved surfaces. Said inspection device comprises a support element ( | 12-27-2012 |
20130321796 | INSPECTION DEVICE - The invention relates to a device for inspecting contact-sensitive planar materials or workpieces, e.g. wafers for the semiconductor industry, solar cells, glasses, FPD substrates, or biologically active substrates for biosensors, as well as materials having contact-sensitive curved surfaces. Said inspection device comprises a support element ( | 12-05-2013 |
20140041186 | METHOD FOR LOADING AND UNLOADING A CASSETTE - The present invention relates to a method for loading and unloading a cassette which is used, for example, in plasma coating processes, wherein the following method steps are carried out: a. providing a cassette ( | 02-13-2014 |
20150015013 | VACUUM GRIPPER - A vacuum gripper for gripping a work-piece includes a flat or curved gripper plate having at least one suction port. A work-piece suction throttling zone is formed around the suction port. The gripper plate has at least one recess provided at a side facing the work-piece and arranged beyond the work-piece suction throttling zone ( | 01-15-2015 |
20150321321 | Device For Gripping Substrate Without Contact - A device for gripping a substrate without contact with which the substrate can be more securely transported. In the device, a housing cap has an air inlet in the upper surface and a lower opening, the lower opening communicating with the air inlet such that air introduced through the air inlet exits through the lower opening. A contour of the lower opening in its vertical cross section is convexly rounded such that the introduced air is guided along a horizontal undersurface of the housing cap. A nozzle is disposed in an inner hollow space of the housing cap, and has an inclined surface such that the width of the nozzle gradually decreases in the direction from the undersurface of the nozzle to the upper surface of the nozzle adjacent to the air inlet. The undersurface of the nozzle is at a predetermined distance from the inner surface of the housing cap. An ultrasonic shaker applies ultrasonic vibration to the housing cap. | 11-12-2015 |
