Description

Technical Field

[0001] The invention relates to the technical field of vacuum glass processing, in particular to a vacuum glass degassing device. Background Art

[0002] Vacuum glass has been widely used in the fields of construction, home appliances, etc. due to its excellent heat insulation and sound insulation properties. However, in the production process of vacuum glass, removing the air in the glass interlayer and effectively sealing it is a key link. Current technology still has some shortcomings in this regard. During the vacuuming process, traditional vacuum glass degassing devices can often only perform single vacuuming on the glass interlayer, and cannot simultaneously vacuum the space around the glass. This results in the sealing link after the vacuuming is completed. The outside air easily interferes with the vacuuming effect of the glass interlayer, making it difficult to fully remove the air in the glass interlayer, thereby affecting the vacuum degree and performance of the vacuum glass. In the sealing link, it is difficult for existing devices to seal the glass interlayer in an environment with thinner air. When the vacuuming is completed, since there is still a certain amount of air in the surrounding environment, during the sealing process, this air will enter the glass interlayer due to the atmospheric pressure, resulting in a decrease in the vacuum degree and reducing the quality of the vacuum glass.
