Abstract

PURPOSE:To perform the measurement by moving a contact probe to a measuring point with a robot hand when it is necessary to adjust a trimmer automatically by observing the characteristics in contact with a measuring terminal in a circuit. CONSTITUTION:When an adjusting trimmer 11 of a circuit board 10 is turned and adjusted with the signal at the measuring point of the board being observed, a measuring probe is brought into contact with the measuring point beforehand. The measuring probe holds a knob 3 with a robot hand 1 and moves the knob 3 to the position of the measuring point in the directions of X, Y and Z. Then, a pump 5 operates to suck a sucking plate 8 of the probe. Thus, a needle 7 continues contacting the measuring point even if the knob 3 is separated, and the measurement can be performed with a measuring device 4. After the finish of the movement of the measuring probe, a driver 2 is held with the robot hand 1, and the driver moves to the position of the trimmer 11. The trimmer is turned, and the measuring probe and the driver move to the other positions. All the operations are performed in predetermined specified sequence with a control part 13.
