PURPOSE:To shorten the adjusting time of an optical axis and to enhance the adjusting preciseness thereof, by automating the adjustment of the optical axis by the operation of an adjuster screw grasped by an industrial robot. CONSTITUTION:The car kind signal of a car body 2 to be inspected is outputted to an aiming control apparatus 41 and a robot control apparatus 42 from a tact line control apparatus 40 and the position of a light receiving screen 25 is determined at an optical axis objective position. In the next step, when a car truck 4 is stopped at a predetermined inspection position and subjected to positional determination by a locating pin 7, a reflex mirror 15 is set and lamps are lighted. The lights from the lamps R, L irradiate the light receiving screen 25 while are reflected by the mirror 15. The inspection and adjustment of the lamp optical axes in the up-and-down direction and the left-and-right direction are performed by the sequence circuit of the aiming control apparatus 41. This aiming control apparatus 41 compares the received luminous intensity values of light receiving sensors 26a-26d and sends a rotation order signal to a driver unit 12. The robot control apparatus 42 receives the adjustment order signals of the up- and-down and left-and-right directions to practice program content. |
