LASER PROCESSING DEVICE PROVIDED WITH INFRARED CAMERA FOR DETECTING OUTBREAK OF FIRE, AND FIRE OCCURRENCE DETECTING CAMERA FOR LASER PROCESSING DEVICE

摘要

This laser processing device provided with an infrared camera for detecting an outbreak of fire includes a laser processing head 9 which moves relative to a workpiece W positioned inside a laser processing region, and subjects the workpiece to laser processing. An infrared camera 19 for detecting an outbreak of fire in a space above the laser processing region is provided in a position higher than the workpiece processing position. The laser processing head 9 is provided with freedom to reciprocate in at least one of an X-axis direction and a Y-axis direction relative to the workpiece W, and the infrared camera 19 is provided in a fixed position outside a zone of movement of the laser processing head 9.
