[0042] 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, drill a through hole at the corner of the upper glass 1 as the air outlet 3, and drill a hole around the periphery of the lower glass 2 and the air outlet. 3, a sealing groove 6 is set up at the corresponding place, and the edge grinding, chamfering, cleaning and drying are carried out, and the sealing strip 5 is prepared by mechanical spraying technology on the peripheral welding part of the upper glass 1 and the periphery of the suction port 3, and is applied on the upper and lower sides by a glue dispenser. Glass preparation support 8; secondly, put the upper and lower pieces of glass into the mold, put them in ...
