Problems solved by technology

[0003] One of the key processes in the manufacture of vacuum glass is to arrange the support (cloth support) in the two-layer vacuum glass. Because the support is small in size and easy to move, it is very difficult to arrange, so the vacuum glass cloth support has always been a difficult problem in the manufacture of vacuum glass. One of the reasons for the low yield of vacuum glass

Abstract

The invention discloses a 3D printing device for a vacuum glass support. The 3D printing device comprises a near-net forming 3D laser printing head, a workbench for bearing glass, a three-dimensionalmoving sliding table and a set of PLC printing controller. According to the invention, the low-temperature glass powder is printed and formed into the support by adopting the near-net forming 3D printer, so that the manufacturing process of the vacuum glass support can be basically solved, the production automation degree and the yield are improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of vacuum glass manufacturing, in particular to a 3D printing device for a vacuum glass support. Background technique [0002] As the country and development enterprises have higher and higher requirements and standards for building energy conservation, vacuum glass has been paid more and more attention by construction and other industries due to its outstanding advantages such as energy saving and sound insulation. However, due to the fact that some key technologies for manufacturing vacuum glass have not been fully mastered, it is currently only a niche product in the entire architectural glass family. With the continuous improvement of building energy-saving standards, especially passive houses or near-zero energy buildings have been piloted and promoted in many places, ordinary Low-E insulating glass can no longer meet the requirements, so the voice of vacuum glass is also getting higher and higher , more and mor...
