DEVICE FOR MEASURING QUANTITY OF COMPONENT

摘要

PURPOSE: A component quantity measuring apparatus is provided to automatically measure the number of components by sensing a sound wave generated from falling collision as an electric signal. CONSTITUTION: A component supply unit(110) receives a plurality of components. The component supply unit drops a plurality of the components. A sound wave generating unit(120) generates sound wave if the fallen components are in a collision. A quantity detection unit(130) detects the generated sound wave. The detection unit detects the quantity of components according to the sound wave.
