Abstract
The utility model provides an alignment focusing laser welding device, comprising an alignment head, a connecting head and a focusing head, wherein the connecting head is used for connecting the alignment head with the focusing head by a flange structure. The device also comprises a protection air knife which is arranged on the focusing head. The alignment focusing laser welding device is provided with the protection air knife, so that in welding, metal particles splashed from metal under the condition of melting are blocked by protection air blown out from an air outlet of the protection air knife. Meanwhile, the protection air also has a role of cooling solidification. Thus, the cleanness of protection glass and focusing lenses is ensured, and the protection glass and the focusing lenses are not damaged. Meanwhile, the service life of the alignment focusing laser welding device is prolonged.
