Title:
LASER CUTTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/006855
Kind Code:
A1
Abstract:
A laser cutting device comprises: a main body (1) used to emit a laser beam (11) forming a cutting point at a location where the laser beam and a material to be cut intersect with each other; an air jet nozzle having an air jet opening (30) used to output an air flow in an angle to the laser beam (11), wherein the air flow is accurately directed to the cutting point; and an air suction tube having an air suctioning opening (40) located at downstream of the cutting point in relation to an air flow direction. The air jet nozzle and the air suctioning tube can be respectively attached via an adjustment mechanism to the main body (1) to adjust the air jet nozzle and the air suctioning tube, so as to adapt to a change in a cutting path of the laser beam (11). The laser cutting device can ensure a cutting effect while effectively reducing contamination in areas at two sides of a cutting line on a film material (6), and is particularly suitable for cutting a flexible film material (6).
