自动磁芯分选系统

An Automatic Grading System for Magnetic Cores

本文介绍了一种可按磁导率μ值相对偏差大小,对磁芯进行自动分选的机电一体化系统,它由自动磁芯分选仪(主机)、驱动电源、传输机构三个独立部件组成.该系统具有自动预测、自动分选、自动计数等功能.分选精度:±0.5%,分选速度>0.5颗/秒,并可适应对多种规格磁芯进行分选.多项试验表明,该自动分选系统能有效地解决国产磁芯μ值离散性大的难题,对提高磁芯电感器的精度和成品率有明显效果.

This paper describes an electromechanical system for grading magnetic cores in terms of their relative error of magnetic conductivity (μ). It consists of automatic grading equipment for magnetic cores (main engine) .driving power and transmission mechanism. The function of the system mainly includes auto measuring,auto grading and auto counting etc. It's grading precision is ±0. 5% ,and grading speed is more than 1 core for 2 seconds. The system is suitable for grading various magnetic cores, several tests show that the auto grading system has solved the problem about great dispersion of magnetic conductivity of domestic magnetic cores.
