摘要:
A stage apparatus in which a rectangular substrate which is levitated over a stage is transferred such that a pair of sides of the rectangular substrate are substantially parallel to a transfer direction and the other pair of sides of the rectangular substrate are substantially perpendicular to the transfer direction. The stage includes a plurality of gas spray ports to spray a gas and a plurality of suction ports to attract the rectangular substrate by suction. The rectangular substrate is levitated at a predetermined height from the surface of the stage in a substantially horizontal posture by means of suction of a suction mechanism through the plurality of suction ports and gas spray of a gas spray mechanism through the plurality of gas spray ports. The plurality of suction ports are arranged on the stage such that, when the rectangular substrate is being transferred over the stage, the leading end of the rectangular substrate in the transfer direction does not simultaneously cover not less than a predetermined number of suction ports and the trailing end of the rectangular substrate in the transfer direction does not simultaneously open not less than a predetermined number of suction ports to the atmosphere, so as for variations in suction pressure in the suction ports to fall within an allowable range.

A non-contact holder includes: a body 2 having an ejection recess 3 having an ejection opening 3b from which a fluid is ejected and a tapered surface 3c gradually diverging toward the ejection opening; discharge ports 10 provided at positions adjacent to the tapered surface of the ejection recess of the body to discharge the fluid along the tapered surface in the axial direction; a fluid supply channel 7 connected to the discharge ports to supply the fluid; radial flow guides 11 formed on the tapered surface of the ejection recess to guide the flow of the fluid discharged from the discharge ports radially outward from the center of the ejection recess; and a flat end surface 4 formed integrally with the outer edge of the body around the ejection opening and opposed to the surface of a workpiece 5 opposing to the ejection opening to guide the flow of the fluid to the outside of the opposite surface of the workpiece 5. The single non-contact holder having the above structure can hold an object to be held, such as a workpiece, with less noise and lower cost without the rotation of the object.

A substrate conveyance device for fabricating a liquid crystal display device is provided. The substrate conveyance device conveys substrates and aligns substrates without using an additional aligning apparatus. The substrate conveyance device includes an arm that forms a body of the substrate conveyance device, a hand and a mover. The hand, that is movable in a first direction, includes a first end coupled with the arm and an upper surface where a substrate is placed on the upper surface. The hand also has a holder which holds a dummy portion which is at an edge of the substrate. The mover is configured to move the hand.

A pneumatic handling and recoating apparatus for handling workpieces, such as glass, is provided. The apparatus utilizes a holding device operatively connected to a vacuum assembly. The holding device engages workpieces by vacuum and subsequently releases them by a burst of gas. The burst of gas also facilitates the application of a coating material, such as a stain-retardant agent, to a workpiece upon release from the holding device.

A glass-plate working apparatus (1) includes a grinding means (7) for grinding a peripheral edge (6) of a glass plate (2); and a grinding supporting means (9) for supporting the glass plate (2) whose peripheral edge (6) is to be ground by the grinding means (7), wherein the grinding supporting means (9) includes a grinding supporting table (101), a plurality of suction cups (102) which are held on the grinding supporting table (101) by being attached by suction to the grinding supporting table (101) and suck and hold the glass plate (2) by sucking the glass plate (2) whose peripheral edge (6) is to be ground, and an arranging means (103) for disposing the plurality of suction cups (102), respectively, at positions corresponding to the shape of the glass plate (2) to be ground.
摘要:
In a contact-free plate conveyor including an arrangement of nozzles each having a cup-like shape widening to a planar rim thereof, means are provided for supplying air under pressure to the nozzles such that the air flow toward and through a gap formed between the rims of the cups at high speed generates a vacuum between the cup rims and the plate so as to hold the plate at a predetermined distance from the nozzle arrangement.

A method for putting a glass plate to a target position includes (a) putting the glass plate at a preliminary position above an air table that discharges air upwardly, by moving a suction member that supports the glass plate through suction; (b) releasing suction of the suction member, while air is discharged upwardly from the air table, thereby floating the glass plate at the preliminary position above the air table; and (c) moving a pressing member in a horizontal direction, while the pressing member is in abutment with a top surface of the glass plate and while air is discharged upwardly from the air table, thereby moving the glass plate in the horizontal direction from the preliminary position above the air table to the target position above the air table by a frictional force generated between the pressing member and the glass plate.
摘要:
A device for conveying insulating glass panes, which are slightly inclined from the perpendicular, is provided with a horizontal conveyor (2) on which the insulating glass panes stand, and with a supporting device (150), which extends above and parallel to the horizontal conveyor (2). The supporting device (15) defines by one or more supporting elements a pane movement plan (16) against which rest the insulating glass panes of the horizontal conveyor (2). The horizontal conveyor (2) has two parallel and synchronously drivable conveying elements (7,8), supporting surfaces (10,11), which are aligned substantially vertical to the pane movement plane (16). The distance of one of the conveying elements (7,8) from the other conveying elements (8,7) is variable. The conveying elements (7,8) are movable independently of one another transverse to the pane movement plane (16).
