圆柱锂电池隔膜错位与锥形

2022-09-15

锂电池

一、圆柱锂电池隔膜(mo)错(cuo)位与(yu)锥形的原因

1、线圈针是(shi)否同(tong)心;

2、线(xian)圈针(zhen)与基板不垂(chui)直;

3、上下隔膜的(de)后过(guo)渡辊与基板不垂直(zhi);

4、辊与辊之间(jian)不平行;

5、隔膜(mo)来料不合格。

二(er)、圆柱锂电池隔膜错位和锥形的修复方法

1、用3.5、4*100圆(yuan)轮(lun)钢、线(xian)圈针套等测(ce)量工(gong)具敲击两(liang)轴之间的(de)同(tong)心度,精度误差为10um;

2、同心度(du)测(ce)量完成后,用垂(chui)直(zhi)量具和方尺测(ce)量卷筒(tong)针与(yu)大(da)板(ban)的(de)垂(chui)直(zhi)度(du)(至少要保证(zheng)两个方向的(de)垂(chui)直(zhi)度(du));

3、用方(fang)尺校准上下隔膜的后(hou)过(guo)渡辊(gun)的垂(chui)(chui)直(zhi)度;(若辊(gun)确实与基材不(bu)垂(chui)(chui)直(zhi),可加(jia)垫片至垂(chui)(chui)直(zhi),并打上记号);

4、先松开橡胶辊和不锈钢辊的螺丝,调整(zheng)其与基材平行垂直(zhi),然后(hou)锁(suo)紧;

5、更换隔膜来料。
