Manufacturing method and manufacturing equipment of vacuum glass

Abstract

The invention provides a manufacturing method and manufacturing equipment of vacuum glass. The manufacturing method comprises the following steps of A, glue dotting on a first glass sheet; B, glue curing and glass tempering; C, placing of the glass sheet; D, vacuum sucking, heating, and sheet closing; E, fetching out. The manufacturing method has the advantages that while the first glass is tempered, the glass powder glue, blocking glue and fulcrum glue are cured, and the glass tempering and the glue curing are simultaneously completed, so that the technology steps are simplified, the preparation time is shortened, and the adhering strength between the glass powder glue, the blocking glue as well as the fulcrum glue and the first glass is improved; by respectively arranging heating bodiesat the upper part and lower part, the heating speed of each glass body is favorably improved; the heat is transferred to the glass in a contact heating way, so that the heat loss is reduced, and the energy-saving effect is realized; the uniform change of temperature at each part of the glass sheet is favorably guaranteed in the heating process; by arranging the blocking glue, the influence to theappearance quality of the vacuum glass due to the flowing of the melting glass power glue to the interior in a tempering furnace is avoided.

Description

technical field [0001] The invention belongs to the technical field of vacuum glass manufacturing, and in particular relates to a vacuum glass manufacturing method and manufacturing equipment utilizing the manufacturing method. Background technique [0002] The vacuum layer of vacuum glass can effectively block the heat conduction between indoor and outdoor, and significantly reduce the pollutants and greenhouse gas emissions of indoor air-conditioning computers. It has good heat insulation performance and can reduce the transmission of noise. Performance applications are very extensive. [0003] At present, the manufacturing method of vacuum glass generally adopts a two-step production process of first sealing the edge at high temperature, installing an exhaust pipeline after cooling down, heating and vacuuming, and finally sealing. The vacuum glass prepared by this method has two defects: one is the preparation time It is relatively long, and it usually takes eight hours ...

Problems solved by technology

[0003] At present, the manufacturing method of vacuum glass generally adopts a two-step production process of first sealing the edge at high temperature, installing an exhaust pipeline after cooling down, heating and vacuuming, and finally sealing. The vacuum glass prepared by this method has two defects: one is the preparation time It is relatively long, and it usually takes eight hours to get vacuum glass; second, the surface of vacuum glass has air holes, and the surface of vacuum glass has different pressure bearing capacity, and it is not beautiful at the same time; and not only the production capacity is low, but also the cost is high and the pass rate is low.
