Description

TECHNICAL FIELD [0001] The present invention relates to a laser apparatus for verifying a laser beam,

The present invention relates to a laser device verification method using a reflector, and more particularly, to a laser device verification method using a reflector for verifying the accuracy of a laser device used in an aircraft panel manufacturing process.

In general, the laser device can be configured to project various images based on light onto an object. The prior art for such a laser device has already been disclosed in Korean Patent Laid-Open Publication No. 2010-0113124 (Optical Projection Apparatus, October 20, 2010).

On the other hand, such a laser device is used in an aircraft panel manufacturing process.

10 and 11, in the aircraft panel manufacturing process, the composite material 30 is placed on the base 10, and the laser device 100 is disposed on the composite material 30. Thereafter, information on the shape and size of the aircraft panel is input to the laser device 100, and the laser device 100 causes the image 50 corresponding to the set shape and size to be projected onto the composite material 30. Thus, a plurality of composite materials 30 cut and cut along the image 50 are heat-treated to manufacture aircraft panels.

In such an aircraft panel manufacturing process, numerical verification of the image 50 projected from the laser device 100 onto the composite material 30 is required. That is, it should be verified that the image 50 irradiated from the laser device 100 is equal to the size of the image actually required. In the conventional case, the size of the projected image 50 on the composite material 30 is simply measured using a ruler or the like. However, in this case, it is difficult to obtain the verified data and the verification time is delayed according to the shape and size of the image .
