摘　　要：针对某型精密仪表马达定子铁芯叠片粘接质量差、线切割合格率低等问题,检测和分析了线切割开裂机理,研究了叠片表面清洗剂、清洗方法以及偶联剂添加对铁芯叠片粘接质量的影响。结果表明,使用CT-208A清洗剂并采用超声清洗方式可以有效清除表面污物并且无溶剂残留。在KH-225胶中添加1%的KH-550偶联剂,叠片间撕开力可提高约103%。将表面清洗方法和偶联剂应用于叠片粘接过程后,马达定子铁芯线切割合格率提高到90%以上。In order to improve the bonding strength between core sheets and prevent sheets cracking from cutting,the mechanism of cracking is analyzed.Effect of surface cleaner,cleaning method and coupling agent addition on bonding strength between core sheets is studied.The results show that surface pollution is removed effectively by using cleaner CT-208 A and ultrasonic cleaning method.Tear strength between sheets is improved by 103%with only 1%addition of coupling agent KH-550 into KH-225 adhesion.By applying the above cleaning method and coupling agent in the bonding process,the cutting yield of motor stator core sheets reach more than 90%.
