Sealing device for slot-type vacuum glass

A slot-type vacuum glass sealing device comprising:

• an inductive heating device;
• conveyor rollers;
• and
• wherein the inductive heating device is arranged between the conveyor rollers and wherein a glass sheet to be sealed is conveyed by the conveyor rollers and passes through the inductive heating device;
• and
• wherein the inductive heating device comprises an elongated casing having a rectangular slot extending from a front side of the casing to a back side of the casing, and inductive heating coils arranged around the slot inside the casing, and wherein the glass sheet to be sealed enters the front side of the casing, passes through the slot and exits from the back side of the casing and the entire circumference of the entire glass sheet is gradually hermetically sealed through a metal brazing process in one pass as the glass sheet passes through the slot without changing travel direction;
• wherein the position of the slot is matched with a supporting face of the conveyor rollers and wherein conveyor rollers at the front side of the casing and the back side of the casing are arranged close to the slot;
• wherein the glass sheet to be sealed comprises two or a plurality of glass sheets, and the circumference of the glass sheet is provided with a metal layer which is fixedly bonded therewith;
• wherein the hermetical sealing means that the metal layers, corresponding to each other, at the circumferences of two adjacent glass sheets are directly interconnected in a manner of hermetical welding, or a metal sealing piece is arranged between the metal layers, corresponding to each other, at the circumferences of two adjacent glass sheets, and the metal sealing piece is respectively connected with the metal layers on the two glass sheets in a manner of hermetical welding.
