<p>According to an embodiment of the present invention, a method for inspecting the coating quality of a sealer comprises: a sealer coating step which coats a sealer on a moving object; a laser radiating step which radiates line laser beams to the sealer coated on the object; a photographing step which photographs a laser pattern showing on the sealer where the line laser beams are radiated; and a controlling step which changes the exit position of the line laser beams as the coating direction of the sealer changes. In addition, the laser pattern may include a first pattern (Lu), a second pattern (Lc), and a third pattern (Ld) in order in the coating direction of the sealer. Therefore, the apparatus and method for inspecting the coating quality of a sealer can increase the accuracy of inspection by changing the exit position of the line laser beams in the coating direction of the sealer changes.</p> |
