Edge sealing method for vacuum glass

Abstract

The invention discloses an edge sealing method for vacuum glass. The edge sealing method uses a set of edge sealing devices, wherein the edge sealing devices comprise a main cavity chamber, a secondary cavity chamber, a vacuum valve and a plurality of drawers, wherein an insertion opening for inserting the drawers is formed in one side surface of the main cavity chamber; a plurality of guide railsof the drawers are formed in the main cavity chamber from top to bottom; a plurality of the drawers are respectively and correspondingly connected to the guide rails of the drawers one by one in a sliding manner; the main cavity chamber is sealed after a plurality of the drawers of the main cavity chamber are inserted into the main cavity chamber; and a plurality of drawers divide the inner spaceof the main cavity chamber into a plurality of layers, and a heating mechanism is arranged on the side wall of the main cavity chamber of each layer, the main cavity chamber is communicated with thesecondary cavity chamber through a pipeline, and the vacuum valve is arranged on the pipeline. The integral main cavity chamber is evacuated before the toughened glass is sealed, so that the defects of too small vacuum pumping opening and unclean degassing are avoided, and meanwhile, the secondary sealing process is reduced.

Description

technical field [0001] The invention relates to the technical field of vacuum glass processing and manufacturing, in particular to an edge sealing method for vacuum glass. Background technique [0002] In recent years, with the general public's awareness of environmental protection and the country's emphasis on energy conservation and emission reduction, all walks of life have vigorously developed energy-saving equipment and products. In the construction industry, civil products and other fields, there are many places that need excellent and beautiful products. Thermal insulation materials to save energy consumption, such as doors and windows in the construction industry, thermal insulation cabinets in the civilian field, automotive glass, etc., the thermal insulation performance of existing products cannot meet the needs of the current situation; at present, a vacuum glass product recognized by the society has Excellent physical properties of heat insulation, noise reductio...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the deficiencies in the background technology, the purpose of the present invention is to provide a method for sealing edges of vacuum glass. The present invention completes the process of vacuumizing the whole chamber in one step in the multi-layer drawer-type main chamber, and then heating the sealing material to 300℃-350℃ directly remove the residual gas on the inner surface of the vacuum glass to obtain a clean vacuum chamber, then continue heating for welding, and directly obtain vacuum glass after cooling down, so as to solve the complex process and long time in the traditional two-step method , use more equipment, poor vacuum degree and other disadvantages
