CO2 laser welding apparatus

Abstract

The invention relates to a carbon dioxide laser welding device, which comprises a carbon dioxide laser, a controller, a lens system, and a carrier, wherein said carbon dioxide laser can generate laser; the controller controls the laser; the lens system is used to focus the laser into the welding seam; the carrier has a cooler; when welding, the work piece is arranged on the cooler, then using the welding device to smoothen the welding seam, with strong combination.

Description

【Technical field】 [0001] The invention relates to a laser welding device, in particular to a carbon dioxide laser welding device. 【Background technique】 [0002] As a transparent material, glass is widely used in various computers and consumer electronics products, such as glass panels in various display screens. During the processing of glass, it is often encountered that two pieces of glass need to be welded together. [0003] Traditional welding methods include fusion welding, brazing, etc., fusion welding will have a more obvious weld seam, and brazing will introduce impurities. In the 1970s, laser welding began to be used, but it was mainly used for welding thin-walled materials. [0004] With the emergence of high-power carbon dioxide lasers, laser deep penetration welding can be applied in industry. When the laser is used for deep penetration welding, the high power density laser evaporates the material on the surface of the workpiece to form a small hole. The smal...

Problems solved by technology

[0005] In the above-mentioned condensation process, if the heat distribution is uneven and fast, it will cause local overheating at the weld seam, and eventually cause poor welding. The weld seam is not smooth from the outside, and the welding seam has insufficient bonding force
