Description

[0001] The present invention relates to a vacuum window manufacturing apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing furnace apparatus for a vacuum window manufacturing facility, and more particularly, to a sealing furnace apparatus for a vacuum window manufacturing facility capable of heating a pallet equipped with a vacuum window glass plate at a high temperature.

Generally, a vacuum window is a kind of a window that enhances heat insulation by blocking heat and noise transmitted from the outside as well as blocking noise and vibration transmitted from the outside by forming a vacuum between the upper plate and the lower plate.

In order to manufacture such a vacuum window, conventionally, a frit seal is applied to the edge of a glass plate composed of a pair of upper and lower plates, followed by heat treatment, cooling at room temperature, and then vacuuming between the upper and lower plates .

Particularly, an exhaust hole is formed in the lower plate, a short pipe-shaped tip is provided around the exhaust hole, and a vacuum hose is connected to the tip to exhaust air between the upper plate and the lower plate to form a vacuum Next, a method of sealing the vacuum chamber by sealing the tip with the vacuum hose removed is applied.

However, the conventional vacuum window manufactured in this manner has a problem that a portion of the tip is fused and protruded to remain on the surface of the lower plate, the surface is not smooth, the degree of vacuum that can be formed by the vacuum hose is low, There is a problem that the product is damaged due to the external force.

Particularly, in the conventional vacuum window manufacturing method, there is no way to securely transport a giant glass plate in a high temperature and high vacuum environment, and at the same time, to heat at a high temperature, so that a series of processes can not be automated and line- There is a problem that the productivity is greatly reduced.
