    • A laser processing device in which even a short nozzle provided with a follower roller (35) can prevent disturbance of a laser beam and contamination of protective glass and in which shield gas can act effectively. The laser processing device comprises a head section (11) from which a laser beam that is condensed by a condenser lens (16) provided inside the device is irradiated through a nozzle section (13); a gas delivery means (28) opened in a processing direction X, in the vicinity of the focal point of laser beam, and jetting a shield gas from the opening; a primary air delivery means (31) directed in the processing direction X, above the focal point F of the laser beam, and jetting primary air A1 substantially in the horizontal direction to form a first air curtain; and secondary air delivery means (18, 13, 19) directed to the focal point from the vicinity of the condenser lens and jetting secondary air A2 to form a second air curtain.
    • 一种激光加工装置,其中即使设有从动辊(35)的短喷嘴也能够防止激光束的干扰和保护玻璃的污染,并且其中保护气体可以有效地起作用。 激光加工装置包括头部(11),通过设置在装置内部的聚光透镜(16)聚光的激光束通过喷嘴部分(13)被照射; 在处理方向X上在激光束焦点附近开口的气体输送装置(28),并从开口喷出保护气体; 沿着处理方向X指向激光束的焦点F上方的一次空气传送装置(31),并且基本上沿水平方向喷射一次空气A1以形成第一气帘; 以及从聚光透镜附近指向焦点并喷射二次空气A2以形成第二气帘的二次空气输送装置(18,13,19)。
