[0045] Example: see figure 1 , The convex vacuum glass is composed of an upper glass 1 and a lower glass 2, the periphery of the two pieces of glass is welded together by glass solder 4, and the middle is a vacuum layer. The production method is as follows: First, cut two pieces of flat glass according to the shape and size of the convex vacuum glass to be produced, and drill a through hole at the corner of the upper glass 1 and the lower glass 2 as the air inlet (installation hole) 3, Set up a sealing groove 6 around the periphery of the lower glass 2 and corresponding to the air outlet 3, and perform edge grinding, chamfering, cleaning, and drying, and use mechanical spraying technology to prepare sealing strips at the peripheral welding of the upper glass 1 and the periphery of the air outlet 3 5. Use a dispensing machine to prepare supports 9 on the upper and lower glass, and then make a silver paste layer 8 on the sealing strip around the air inlet 3 and the surface of th...
