一、前言钕铁硼是我国近年来研究开发的高磁能级新颖磁性材料。由于它具有优异的磁特性,广泛应用于机械、电子工业等各个领域。生产批量正在日益增加,并已大量出口。但由于目前国内外尚无自动检测系统,只停留在落后的手工检测状态,不仅效率低,且分选质量不能保证,常引起出口产品质量纠纷。为此,宁波市电子技术研究所在近期研制开发了具有充磁、检测、退磁、分选诸种功能的自动检测系统。本系统为机电一体化产品,实行微机全自动控制。钕铁硼为高强
I. Introduction NdFeB is a new type of magnetic material with high magnetic energy level developed and researched in China in recent years. Because of its excellent magnetic properties, widely used in machinery, electronics and other fields. Production batches are increasing and have been exported in large quantities. However, at present, there is no automatic detection system at home and abroad, only stay behind the manual detection of state, not only inefficient, and sorting quality can not be guaranteed, often causing export product quality disputes. To this end, Ningbo Institute of Electronics recently developed a magnetizing, testing, demagnetization, sorting various functions of the automatic detection system. The system for mechatronics products, the implementation of microcomputer automatic control. NdFeB high strength
