AUTOMATIC CALIBRATION SYSTEM FOR 20 kg WEIGHTS BY ROBOT AND WEIGHT MAGAZINE
MIN-SOO LEE, WOON-YOUNG KWAK · International Journal of Modern Physics Conference Series · 2013
This paper presents the method that can calibrate the weights (10 kg ~ 20 kg) automatically by a 3-axis robot, three weight carrier magazines. So the operators do not need to take an effort to align weight on the pan of the balance manually during calibration procedure, and can calibrate the weights automatically during night. The weight calibration system consists of a 3-axis robot, a weight magazine, and operating software to avoid temperature and air flow effect from human. At first the calibration system moves weight on the magazine to the pan of balance. Second measures the mass of the weight, and then moves the weight to the original position on the magazine automatically. This automatic moving method not only avoids the introduction of excess uncertainty, but also improves productivity. Hereafter the similar system can be applied to the calibration of other range weights (1 mg ~ 5 g).
