Abstract
A laser shielding device interposed between the camera and the reflected light and is provided with a plurality of plates juxtaposed at an interval. Of the plurality of plates, an incident-side plate disposed on an incident side of the reflected light may be made larger in heat capacity compared to other plates disposed on the camera side of the incident-side plate.
Claims6
A laser shielding device for shielding reflected light directed toward an object to be shielded in a laser processing machine having a laser irradiation unit configured to irradiate laser light on a workpiece, and the object to be shielded disposed within a range which the reflected light of the laser light reaches, the laser shielding device comprising:
- a plurality of plates interposed between the object to be shielded and the reflected light and juxtaposed to one another at an interval;
- wherein of the plurality of plates, an intermediate plate disposed between an incident-side plate disposed on an incident side of the reflected light and an object-side plate disposed adjacent to the object to be shielded is larger in thermal resistance compared to each of a rest of the plurality of plates.
