Problems solved by technology

[0014] At this time, if ceramics with excellent heat resistance are used for the platform unit and the positioning pins, the cost will increase
Furthermore, if cheap metal positioning pins are fitted or screwed to a ceramic platform, the ceramic platform may be damaged due to the difference in thermal expansion coefficient between ceramics and metal.

Embodiment Construction

[0047] Hereinafter, preferred embodiments of the platform unit of the present invention will be described in detail with reference to the drawings. exist figure 1 The platform unit 1 of the first embodiment is shown in . For example, when heat-processing a thin-plate glass substrate 2 with a thickness of about 1 mm or less used in a portable communication device, the stage of the present embodiment is used when the glass substrate 2 is positioned on the stage 3 and transported into a heating furnace. Unit 1. In this embodiment, the stage unit 1 on which the rectangular glass substrate 2 is mounted is taken as an example and demonstrated.

[0048] Such as figure 1 As shown, the platform unit 1 has: a platform 3 made of ceramics, on which a glass substrate 2 for heat treatment is placed; a plurality of loose holes 4, which are arranged on the platform 3 at positions where the glass substrate 2 is positioned, And the upward and downward direction is penetrated and formed; A p...

Abstract

The invention provides for a surface plate unit capable of locating a glass panel being heat treated on a ceramic surface plate through metal pins and capable of producing easily and in a low cost. A surface plate unit includes a ceramic surface plate 3 on which a glass plate 2 being heat treated is placed, a plurality of loosen holes 4 penetrating the surface plate vertically, the loosen holes being arranged at positions where a periphery of the glass plate is located, a plurality of metal pins 5 loosely inserted into the loosen holes respectively, and connecting members 6 connecting each of two adjacent pins on the surface plate so as to maintain a protruding condition that the pins protrude over the surface plate from the loosen holes.

Description

technical field [0001] The present invention relates to a stage unit capable of positioning a glass substrate to be heat-treated on a ceramic stage using metal positioning pins with a simple and inexpensive structure. Background technique [0002] Conventionally, Patent Documents 1 to 3 are known as techniques for maintaining the position of a workpiece when processing a thin-plate-shaped workpiece. The "work lifting device" of Patent Document 1 is a workpiece lifting device for lifting and lowering a workpiece with respect to a load that absorbs and holds a thin plate-shaped workpiece and performs a predetermined process on the workpiece. For cylinders that drive lift pins up and down, set the force of the lift pins to push the workpiece up to 10 times the weight of the workpiece. [0003] The "substrate holder" of Patent Document 2 includes a substrate supporting member, a pressing pin and a pressing pin, an elongated supporting plate, and an elevating device. There is a...
