Problems solved by technology

After decades of research and development, although the sample and small-scale production technology of vacuum glass has matured, due to the complex structure, cumbersome process, high cost and low production capacity of the existing vacuum glass, and it is not easy to produce fully tempered vacuum glass, the vacuum The production and application of glass are greatly restricted
The main problems are that firstly, the welding temperature of glass solder is high, the welding time is long, tempered glass is easy to anneal, and it is difficult to produce tempered vacuum glass; bottom edge sealing) is difficult to produce vacuum glass; third, the two-step method (edge ​​sealing first, then vacuuming) takes a long time to exhaust the glass surface, which generally takes several hours; fourth, continuous and mechanized production cannot be carried out, and the production efficiency is low; these These problems have led to the poor performance, high cost and low production capacity of existing vacuum glass, which has affected the large-scale promotion and application of vacuum glass

Embodiment 1

[0093] see figure 1 , figure 2 and image 3 , the vacuum glass is made up of upper glass 1 and lower glass 2, and its production method is as follows: first cut two flat glasses of required size according to the shape and size of the vacuum glass produced, and carry out edge grinding, chamfering, cleaning and drying; Next, on the upper glass 1, prepare the support 5 with a glass glaze and a glue dispenser, apply a glass solder 3 evenly with a glue dispenser on the periphery of the sealing surface of the two pieces of glass, and use a glass solder 3 on both sides of the glass solder 3 respectively. Glass frit and dispensing machine to prepare two spacers 4; the support 5 is distributed in a lattice whose smallest unit is an equilateral triangle, and the side length of the triangle is 40-50mm. After sintering and curing, the support 5 is approximately hemispherical and its diameter is about 0.6mm; the width of the glass solder 3 is about 2mm, the height is about 2mm, after th...

Embodiment 2

[0095] see Figure 4 , vacuum glass is composed of upper glass 1 and lower glass 2, and its production method is as follows: various equipment are connected into a continuous automatic production line, firstly, the cutting machine cuts two flat plates of required size according to the shape and size of the vacuum glass to be produced Glass, followed by edging machine for edging and chamfering, washing machine for cleaning and drying; thirdly, a dispensing machine applies a glass solder 3 and two spacers 4 on the upper glass 1, and coats the lower glass 2 Two glass solders 3 and three spacers 4; the width of each glass solder 3 is about 3 mm, and the height is about 2 mm. After sintering and solidification, each spacer 4 has a width of about 1.5 mm and a height of about 0.5 mm. The distance between the centers of two adjacent spacers 4 is about 6 mm; then the two pieces of glass enter the drying furnace for drying, and after drying, the two pieces of glass enter the tempering f...
