Laser cutting device of OSRs (optical solar reflectors)

Disclosed is a laser cutting device of OSRs (optical solar reflectors). At present, OSRs are scribed and cut manually with a diamond knife; manual scribing and cutting is required for shape and size, scrap rate of thin, crisp OSRs is up to 90%, and great waste is caused; the OSRs are made of high-rigidity high-crispiness high-melting-point ultrathin quartz glass as base material, and wear and consumption of cutting tools are high. The laser cutting device comprises a housing (1); the housing is provided with a cooling structure (2) connected with a cooling liquid delivery device; a nozzle (3) is mounted at the lower end of the housing; a germanium lens (4) is mounted within the housing and connected with the cooling structure; the housing is provided with a gas delivery pipe (5) connected with an auxiliary gas delivery device; a gas chamber (6) is formed in the housing; a regulating device (7) for regulating a laser beam and gas blow of the nozzle is arranged outside the housing. The laser cutting device is a
