METHOD AND DEVICE FOR SUPPLYING ELECTRONIC PART

摘要

PROBLEM TO BE SOLVED: To improve a production efficiency through an estimation operation for a load weight by calculating such acceleration as the maximum output of a motor is kept, even if the load weight changes, maximum output at all times for operation at optimum tact time. SOLUTION: A control device moves a slide base 12 on which a cassette taperecorder 13 from an original point restoration position at a prescribed acceleration. A thrust is acquired based on the drive current value of a linear motor 14 driven for the movement. A load weight of the slide base 12 on which the cassette taperecorder 13 is mounted is acquired based on the thrust. The cassette taperecorder 13 is moved to a part supply position at the maximum acceleration acquired based on the load weight and the maximum thrust of the motor.
