Glass fusion bonding method, as well as manufacturing method and manufacturing equipment of vacuum glass

Abstract

The invention provides a glass fusion bonding method, as well as a manufacturing method and manufacturing equipment of vacuum glass. The fusion bonding method comprises the following steps: step one, two glass pieces are fixed oppositely in advance, a gap between joint points of the two glass pieces is 0.2 mm wide; step two, an laser beam goes through an optical focus lens, a focus of an output beam is enabled to align to a midpoint position between the joint points and cover a joint region of the two glass pieces at a focus point position, a peak value energy is regulated, and the joint points of the two glass pieces are fused and bonded into a whole, so that a self-adaptive support point that can adapt different gaps is formed after curing, and bond the two glass pieces into a whole. A laser head and a lens are controlled in a three-dimensional mechanical platform, clamping of the glass pieces is controlled by using a sucker array, edge sealing is performed by continuously illuminating laser along an edge sealing line after fusion bonding of a bonding line. A glass piece self-adaptive bonding method provided by the invention has the advantages that the yield of vacuum glass manufacturing is improved greatly, the average service life of the vacuum glass is increased by multiple times, manufacturing efficiency is improved, and cost is reduced remarkably by compared with an existing method.

Description

technical field [0001] The invention relates to glass processing technology. Background technique [0002] The multi-point connection between glass parts has the problem of inconsistency in the microscopic gap between multiple points. The traditional method is to preset the connection object. Because the size of the connection object is inconsistent with the gap between the multi-connection points, resulting in each point after multi-point connection. The force of the connection point is inconsistent, and the force is too concentrated on a certain connection point, resulting in a high damage rate. Typical is the connection between two glasses of vacuum glass. [0003] Vacuum glass refers to the relative placement of two or more pieces of glass with intervals, and a plurality of small isolation support point arrays are set between the glass pieces to resist the external atmospheric pressure after vacuuming. After sealing, a vacuum airtight cavity is formed between the glass...
