PURPOSE:To correctly carry out the drill work for a standard hole even after carrying out baking, etc., of a standard mark on a substrate before applying a variety of processings accompanied with the heating and cooling. CONSTITUTION:An automatic standard hole drilling machine is equipped with a loading stage 1, adjusting stage 2 which searches the standard marks at two places on a printed circuit board which is automatically sent by an image processing device and two rough positioning cameras 5 and obtains the position information of the standard mark, working stage 3 which is equipped with a fine positioning camera 6 which searches the pitch between the standard marks with high precision and measures the pitch, and a drill unit 7 which corporates the X, Y coordinates having the middle point between the measured standard marks as original point and performs the calculation adjustment with the working coordinates which is previously set, and is shifted to the standard pin hole position calculated from the between-standard mark supposed original point of the circuit board designed value and carries out drilling work, and a carrying-out stage. |
