A first substrate, having an evacuation port, and a second substrate are bonded together with a first sealing material in a frame shape interposed between them to create an internal space. The internal space is evacuated through the evacuation port, and the evacuation port is sealed up with the internal space kept evacuated. At this time, a second sealing material inserted into the evacuation port is heated and melted while being pressed toward the second substrate such that the evacuation port is sealed up with the second sealing material melted. The evacuation port and the second sealing material have dissimilar shapes when viewed along the center axis of the evacuation port in a state where the second sealing material has been inserted into the evacuation port but has not melted yet.

A method of manufacturing a glass sheet assembly for a vacuum insulated glass unit includes applying an edge seal made of a first material to a perimeter of a first surface of a first glass sheet. The edge seal defining a discontinuity. The method also includes disposing a first surface of a second glass sheet on the edge seal such that a gap is defined between the first surface of the first glass sheet and the first surface of the second glass sheet. The method further includes evacuating the gap through the discontinuity and locally heating the edge seal to at least partially seal the discontinuity.

The present invention relates to a method for manufacturing vacuum insulating glass, the method involving applying a vacuum sealant to a first surface of a first glass sheet, the vacuum sealant including a plastic film having a preferably rough surface, placing a second glass sheet on the vacuum sealant such that a cavity is formed between the first and second glass sheets and the vacuum sealant, applying a vacuum to an outer surface of the vacuum sealant until a vacuum is formed in the cavity, wherein the first and second glass sheets are placed in a vacuum bag to apply the vacuum, and heating the vacuum sealant while the first and second glass sheets are in the vacuum bag.

Provided is a vacuum insulation glass panel assembly manufacturing method and apparatus. The vacuum insulation glass panel assembly manufacturing method includes an edge sealing step of sealing an edge of a glass panel assembly of glass panels spaced apart at a predetermined interval, and an exhaust port sealing step of causing a lid member to seal an exhaust port of the glass panel assembly formed so as to communicate with a space between the glass panels whose edges are sealed. A glass solder having a high melting point is used in the edge sealing step, and a glass solder having a low melting point is used in the exhaust port sealing step. A specially designed lid member closing device is used for exhaust port sealing.

A gas adsorption unit includes a getter, a package encapsulating the getter, and a low-melting member. The low-melting member is heated, and thereby melted, at a temperature lower than a melting point of the package to bond a connector including the low-melting member onto the package. Next, the low-melting member that has melted is cooled and cured. Then, thermal stress resulting from a difference in thermal expansion coefficient between the package and the connector is caused to the package connected to the connector, thereby breaking the package open.
