  • Patent number: 10829984
    Abstract: A method for making a vacuum insulated glass window assembly is provided in which an amount of wet frit material is applied to a lower portion of a pump-out tube prior to insertion of the tube into a hole formed in a glass substrate of the VIG window assembly. The tube is then inserted into the hole, frit paste end first. An amount of frit may overflow the hole and form a bump/shoulder of frit material proximate the area of the hole on an outer surface of the glass substrate. Applying the fit to the tube prior to insertion and at a lower portion thereof reduces the amount of and/or avoids residual frit being deposited in an area of the tube that might significantly interfere with subsequent sealing processes, such as, for example, laser sealing of the pump-out tube.

  • Patent number: 10435938
    Abstract: A vacuum insulated glass (VIG) window assembly and method for making same is provided in which a variation in the final edge seal height is preferably 0.20 mm or less, more preferably about 0.15 mm or less. Controlling final edge seal height variations substantially reduces breakage of the glass substrates of the VIG window assembly during vacuum pump-down of the cavity between the glass substrates. Edge seal height variation may be controlled, for example, by controlling initial dispensing of green frit material, controlling temperature variations during firing, and/or controlling cycle times during firing.

  • Patent number: 10427395
    Abstract: Methods of making vacuum insulated glass (VIG) window units are provided, including activating getters in a process of making VIG window units. In certain example embodiments, at least one getter is activated during and/or at the end of a pump-out/evacuation process in which the cavity between the substrates is evacuated. In certain example embodiments, the getter(s) may be activated (e.g., by at least a laser beam that is directed through a pump-out tube) during and/or at the end of the evacuation process in which the cavity between the substrates is evacuated to a low pressure that is below atmospheric pressure.

  • Patent number: 10267085
    Abstract: A vacuum insulated glass (VIG) window assembly and method for making same is provided in which dimensions of a hole formed in a glass substrate in which a pump-out tube is to be inserted is selected such that it provides sufficient clearance for efficient insertion and accommodates sufficient adhesive material (e.g., frit inclusive paste), while at the same time providing sufficient support to resist substantial tilting or tipping of the pump-out tube when inserted in the hole. In addition, a length of the pump-out tube is selected so that a distance between a top of the pump-out tube (which is later subjected to heat sealing, e.g.

  • Patent number: 9169155
    Abstract: A method and apparatus for cleaning a cavity of a vacuum insulated glass window assembly is provided in which a cleaning gas mixture of or including ozone is introduced into the cavity of the vacuum insulated glass assembly and allowed to react with residual materials, such as, for example, hydrocarbons and/or polymers. Reacted hydrocarbons and/or polymers are then removed from the vacuum cavity along with any residual cleaning gas mixture. The cleaning method is preferably performed at substantially ambient temperatures or at least temperatures below about 250° C. The ozone cleaning cycle may be repeated multiple times and followed by additional purges with other gases, such as for example nitrogen. Additional energy may be provided by heating, RF plasma; corona discharge, UV lamp, and/or the like.

  • Patent number: 8833105
    Abstract: A method for making a vacuum insulated glass window assembly is provided in which an exposed end of a pump-out tube of a vacuum insulated glass window assembly is sealed using a laser that is applied to the end of the pump out tube in controlled sequential manner as opposed to a short duration, high-powered application of a laser. In particular, a method is disclosed in which a multiphase sequential variable power application of laser energy to an exposed end of a pump-out tube for controlled exposure times and decreasing laser trace diameters produces a more controlled melting of the tube glass to reduce or eliminate undesirable outgassing that may occur during a high-power short duration exposure of laser energy to the end of the pump-out tube to seal the tube.
