圆柱锂电池

一、圆(yuan)柱锂电(dian)池生产贴胶不良

1、失效原因

(1) 粘胶打邹；

(2) 漏贴现象；

(3) 胶带过渡(du)棒不灵活。

2、修理方法

(1) 制作材(cai)料时，松开(kai)粘合剂固定板的螺(luo)钉(ding)，将(jiang)其(qi)向上抬起一点(dian)，使它们尽可能地(di)与电池芯的中(zhong)心接(jie)触；

(2) 首先，检查粘(zhan)胶胶轮(lun)是否与电芯贴紧(jin)，压带(dai)调节板是否松动(dong)(dong)，送料(liao)导轮(lun)是否过(guo)高，气缸气压是否平(ping)稳，气缸调节距离螺钉是否松动(dong)(dong)，以及上夹(jia)紧(jin)轮(lun)是否压紧(jin)胶带(dai)；

(3) 粘胶机构(gou)前面的轮子与下支撑碰(peng)撞，滚动时不(bu)(bu)能偶(ou)(ou)尔涂胶。在(zai)碰(peng)撞过程中(zhong)，下支撑可能不(bu)(bu)灵活，在(zai)进料时无法向下压，因(yin)此(ci)会导(dao)致(zhi)偶(ou)(ou)尔不(bu)(bu)上胶；

(4) 检查过(guo)渡(du)棒单向轴承是否(fou)向后安装，松开过(guo)渡(du)棒的锁定(ding)套筒，调整(zheng)过(guo)渡(du)棒。

二、圆柱锂电(dian)池生产极片，隔膜错位(wei)

1、失效原因

(1) 下支撑轮(lun)由于两(liang)侧高度(du)不(bu)同造成的；

(2) 极(ji)片导板与(yu)基板不垂直平行。

2、修理方法

(1) 首先，检查电池芯在结束时(shi)是否向内偏置。这(zhei)种现象是下部(bu)支撑的外部(bu)太高(gao)，因此(ci)下部(bu)或(huo)较高(gao)的内部(bu)或(huo)外部(bu)以证(zheng)明电池芯与下部(bu)支撑平行；

(2) 确保极导板(ban)(ban)与基板(ban)(ban)之间的垂直度和(he)平行(xing)度。

三、卷针找不到原点

1、失效原因

(1) 电(dian)感器(qi)故障 (接线断裂、线路接触(chu)不良等)；

(2) 传(chuan)感器有异物(wu)，导致传(chuan)感器不敏感；

(3) 参数设置问(wen)题；

(4) 原点速(su)度问题。

2、修理方法

(1) 检查接线端子(zi)是否完(wan)好；

(2) 用干棉布(bu)擦拭传感器(qi)的(de)发光表面；

(3) 避(bi)免设置长度参数，以确保这些(xie)参数不会加(jia)起来为(wei)整数 (1、2、3、4...，) 等(deng)；

(4) 调整原点速度，以(yi)确保(bao)返回(hui)速度与(yu)PLC响应信号的时(shi)间相(xiang)匹配。
