摘要:
An apparatus for supporting a stationary or moving substantially flat object without physical contact on an fluid-cushion. The object floats on a fluid cushion gap, the apparatus aimed for globally or locally adjusting the gap. The apparatus comprising: a first platform for supporting the object without contact, the platform having a substantially flat active surface comprised of one or more sectors, each sector comprising at least one of a plurality of basic cells, each basic cell having at least one of a plurality of pressure outlets fluidically connected through a pressure flow restrictors to a higher-pressure manifold associated with the sector in which the basic cell lies, the higher-pressure manifold is fluidically connected through main supply pipeline to pressurized fluid supply and at least one of a plurality of fluid-evacuation channels fluidically connected to a lower-pressure manifold associated with the sector in which the basic cell lies having main evacuation pipeline; wherein the flow restrictor characteristically exhibiting fluidic return spring behavior; and wherein at least one pressure control valve is interposed with at least one of the two main pipelines of at least one sector for controlling pressure levels of at least one of the two manifolds of that sector.

An improved method for producing a plurality of parts (30) from a plate-type substrate (20) is disclosed, comprising the steps of: (a) laterally separating the parts (30) from a plate-type substrate (20) fixed on a first vacuum plate (3); (b) sucking the parts (30) on a first vacuum plate (3); and (c) detaching the separated parts (30) from the first vacuum plate (3).
摘要:
A substrate processing table is constituted, in layer form, of a first sub-table, a second sub-table, a rubber plate and a metal plate. A plurality of substrate adsorbing holes are provided which penetrate through the sub-tables, the rubber plate and the metal plate to suck the substrate. Further, a plurality of hard-sheet adsorbing holes are provided which penetrate through the second sub-table and the rubber plate to suck the metal plate. At the time of fixing the substrate, air is discharged via a cavity portion formed on the lower side of the second sub-table, and the pressure of each of the adsorbing holes is made negative. With such a configuration, it is possible to improve a method for holding a substrate so as to improve a scribe function in a scribe step and a break function in a break step at the time of dividing the substrate.

A conveyor 1 for holding glass plates 2 in position during grinding and drilling operations comprising one or more than one belt 3, 3′ 3″ having a rotating surface and a suction generator 6 for generating a vacuum on the surface.
摘要:
A noncontact glass sheet stabilization device is described herein that is capable of reducing translation (deflection) and/or rotational movement of a glass sheet while the glass sheet is being manufactured in a glass manufacturing system that implements a fusion process. Several different embodiments of the noncontact glass sheet stabilization device are also described herein.
摘要:
An apparatus for handling material of the type in sheets or portions of flat sheets, includes at least one device with an autoselection function for the lifting-release of the material, of the type with a vacuum that is obtained between the sucker and the material, by a vacuum forming device through the Venturi effect or by means of a vacuum pump. This apparatus is made up of a multi-way pneumatic supply circuit of an auto-selection and auto-relief valve that includes principal pneumatic commutators. The commutators are interconnected to a third commutator that is interposed between the vacuum forming device and the auto-selection valve that supplies the sucker.
摘要:
A support structure utilizes a combination of positive pressure openings and negative pressure openings to precisely position a workpiece, such as a sheet of float glass. The positive pressure openings are supply openings that direct a flow of fluid, such as air, onto the surface of the workpiece. The negative pressure openings are exhaust openings that are used to regulate the leakage of fluid from between the workpiece and the support structure. In the preferred embodiment, the surface of the support structure includes raised regions that surround the exhaust openings and that function as self-regulating pinch valves. This arrangement enables an equilibrium condition to be quickly established and maintained upon placement of the workpiece on the support structure.
