目的 为了方便快捷地实现硬币的分类与清点，设计研制了一种新型自动硬币分点机械装置。方法 利用送币漏斗和水平传送带将混合硬币（1角、5角及1元硬币）运输至倾斜滑道，通过低频振动和直径筛选对硬币进行快速分类，然后在基于C语言、单片机和压力传感器开发的控制程序作用下对硬币进行称量计数，并在液晶屏上实时显示清点结果，直至硬币分点完毕。结果 研制的实验样机造型轻巧、性能可靠，能够快速、精确地对硬币进行自动分点，最大硬币分点量约260枚/min。结论 该装置有效降低了硬币分点的技术难度和复杂性，可适用于硬币流通量大的工作机构和生活场所，具有较好的应用价值和推广前景。

The work aims to design and develop a new type of automatic mechanical device used to sort and count coins conveniently and quickly. The mixed coins (1 jiao, 5 jiao and 1 yuan) were transported to inclined ramp by feeding funnel and horizontal conveyor belt, and the coins were quickly sorted through low-frequency vibration and diameter filter. Then, the coins were weighed and counted under the control program developed by C language, single chip microcomputer and pressure sensor; besides, the results were displayed on the LCD screen in real time until the coined were sorted and counted. With light structure and reliable performance, the developed experimental prototype could automatically sort and count the coins quickly and accurately, and the maximum amount of the coins suitable to it was about 260 per minute. The device effectively reduces the technical difficulty and complexity of the coins' sorting and counting. It can be applied in some working organizations and living places which need large coin circulation, and has better application value and promotion prospect.
