US 6,682,039 B2 · Locator for a material sheet

Abstract

A locator for a material sheet comprises at least two oppositely disposed stoppers, and a slot sheet. Each of the stoppers provides a flat bearing surface and a slant surface extending outward and upward from the bearing surface with a junction between them. The slot sheet is disposed under the stoppers and joining to a bottom of the respective stopper. The distance between the junctions on the two stoppers is corresponding to the length of the slot sheet.

Dependent claims

A locator for locating a material sheet while performing a manufacturing process thereon, and comprising:

a) a planar slot sheet having an upper surface with opposite ends;
and,
b) a plurality of spaced apart stoppers mounted on the opposite ends of upper surface of the slot sheet, each stopper having a bottom surface engaging the upper surface and extending beyond one of the opposite ends of the slot sheet, a horizontal bearing surface and a slanted surface extending upwardly from the horizontal bearing surface, the slanted surface extending along an entire length of the horizontal surface, wherein a distance between the slanted surfaces increases in a direction away from the horizontal bearing surfaces and wherein the horizontal bearing surfaces are located so as to support a material sheet in a predetermined location with an upper surface exposed.

Dependencies are inferred from the claim text.

#1. Field of the Invention

#The present invention relates to a locator for a material sheet, and particularly to a locator for confining a distance between two end parts of a material sheet effectively.

#2. Description of Related Art

Brief description of the drawings3 figures

#The present invention can be more fully understood by referring to the following description and accompanying drawings, in which:

#FIG. 1 is a perspective view of a stopper according to the present invention;

#FIG. 2 is a side view illustrating a glass substrate being placed on a slot sheet with the stoppers of the present invention; and

Detailed description621 words

#Referring to FIGS. 1 through 3, the locator of present invention used in the preceding load-lock chamber/or heat chamber comprises a slot sheet 1, and at least a stopper 2 at both ends of the slot sheet 1 respectively.

#Wherein, the slot sheet 1 is conventional and can be a sheet provided in the load-lock chamber or a sheet provided in the heat chamber so that a flat plane is provided on the slot sheet 1 with both lateral sides thereof having a stopper or a guard frame to confine a left and a right positions of a glass substrate sheet.

#The crux of the present invention resides in that the slot sheet 1 at the front and the rear ends thereof joins at least a stopper 2 for locating the front and rear ends of the substrate sheet respectively. As shown in FIG. 1, the stopper 2 is solid with a bottom surface 21 to be joined to an end surface of the slot sheet 1 by way of a mechanical or a chemical mode such as threaded fastening, clamping, adhering, and etc. These modes are belonged to prior art and no detail will be described further.
