Abstract

The invention discloses a laser welding device and a welding method thereof. The laser welding device is used for welding glass including an upper glass layer and a lower glass layer which are attached together, and comprises an ultrafast laser device, a 3D galvanometer and a control device. The 3D galvanometer is connected with the ultrafast laser device and comprises a collimating lens used foradjusting the focal length of a laser beam emitted by the ultrafast laser device. The control device is electrically connected with the ultrafast laser device and the 3D galvanometer. By adoption of the technical solution, the technical problem of poor welding caused by flatness changes of the glass during laser welding of the glass in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of glass welding, in particular to a laser welding device and a welding method thereof. Background technique [0002] Glass has special physical and chemical properties, and is widely used in optics, communication, electronics, biomedical and other fields, and glass welding is an important glass forming method. At present, glass welding is mostly applied in the way of adding glass frit or solder. This method has the problems of complex process and high cost of additives. At the same time, due to the different components of additives and glass, there are chemical stability problems. It is necessary to develop a new type of laser glass welding. . Laser glass welding is a new type of glass processing method. Laser welding glass has the characteristics of high efficiency and simple process, but its application requires extremely high flatness of glass. If the flatness changes by 0.03mm, it will cause poor weldi...
