ABB機器人主板(ban)維修中(zhong)(zhong)(zhong)的(de)(de)電(dian)(dian)(dian)(dian)容(rong)損壞(huai)的(de)(de)電(dian)(dian)(dian)(dian)路(lu)(lu)特(te)(te)點(dian)：電(dian)(dian)(dian)(dian)容(rong)損壞(huai)引發(fa)的(de)(de)故障在(zai)電(dian)(dian)(dian)(dian)子設備中(zhong)(zhong)(zhong)常見的(de)(de)，其(qi)中(zhong)(zhong)(zhong)尤其(qi)是電(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)容(rong)的(de)(de)損壞(huai)。?電(dian)(dian)(dian)(dian)容(rong)損壞(huai)表現為：1.容(rong)量變小；2.完全失去容(rong)量；3.漏(lou)電(dian)(dian)(dian)(dian)；4.短(duan)路(lu)(lu)。 ? 電(dian)(dian)(dian)(dian)容(rong)在(zai)電(dian)(dian)(dian)(dian)路(lu)(lu)中(zhong)(zhong)(zhong)所起的(de)(de)作用不同(tong)，引起的(de)(de)故障也(ye)各有(you)特(te)(te)點(dian)。在(zai)工(gong)控電(dian)(dian)(dian)(dian)路(lu)(lu)板(ban)中(zhong)(zhong)(zhong)，數字電(dian)(dian)(dian)(dian)路(lu)(lu)占絕大多數，電(dian)(dian)(dian)(dian)容(rong)多用做(zuo)電(dian)(dian)(dian)(dian)源(yuan)濾波，用做(zuo)信(xin)號耦合和振蕩電(dian)(dian)(dian)(dian)路(lu)(lu)的(de)(de)電(dian)(dian)(dian)(dian)容(rong)較少。

ABB機(ji)(ji)器人芯(xin)片級維修的(de)(de)特點是了解電路(lu)原(yuan)理，掌握(wo)典型電路(lu)，比(bi)如(ru)驅動，顯示，通訊(xun)接(jie)口，遼(liao)寧(ning)機(ji)(ji)器人主板，了解每個芯(xin)片（包括功能腳(jiao)）的(de)(de)功能，資料網上都能找到(dao)，了解單片機(ji)(ji)工作電路(lu)，總線(xian)(xian)(xian)(xian)電路(lu)。就是要有耐心，耐心查看，耐心分析，耐心用各種方法(fa)測試(shi)。焊接(jie)工夫要好，因為有的(de)(de)芯(xin)片要拆下(xia)來才能測試(shi)好壞。如(ru)果熟(shu)悉芯(xin)片的(de)(de)VI曲線(xian)(xian)(xian)(xian)更佳，機(ji)(ji)器人主板維修，先在(zai)電路(lu)上在(zai)線(xian)(xian)(xian)(xian)測試(shi)VI曲線(xian)(xian)(xian)(xian)，曲線(xian)(xian)(xian)(xian)有疑問的(de)(de)再焊下(xia)來進一步確認(ren)。 功能相同(tong)的(de)(de)通道可以(yi)相互對(dui)比(bi)。

機器(qi)人(ren)示教(jiao)器(qi)維(wei)修按(an)(an)下操作(zuo)員(yuan)面板(ban)(ban)上的(de)(de)(de)緊(jin)急(ji)停(ting)(ting)止按(an)(an)鈕(niu)(niu)。松開操作(zuo)面板(ban)(ban)上的(de)(de)(de)緊(jin)急(ji)停(ting)(ting)止按(an)(an)鈕(niu)(niu)。檢查(cha)急(ji)停(ting)(ting)按(an)(an)鈕(niu)(niu)之間的(de)(de)(de)接線(xian)是否連續。如果發現有開著的(de)(de)(de)電(dian)線(xian)，機器(qi)人(ren)主板(ban)(ban)廠家，更(geng)換(huan)整個線(xian)束。當緊(jin)急(ji)停(ting)(ting)機處于釋(shi)放(fang)位置時(shi)，檢查(cha)機器(qi)人(ren)示教(jiao)器(qi)開關端(duan)子之間的(de)(de)(de)連續性(xing)。如果找不(bu)到連續性(xing)，則緊(jin)急(ji)停(ting)(ting)止按(an)(an)鈕(niu)(niu)被斷開。更(geng)換(huan)開關裝置或操作(zuo)面板(ban)(ban)。執行完(wan)整的(de)(de)(de)控制器(qi)備份(fen)，以(yi)保存(cun)所(suo)有程(cheng)序和設(she)置。更(geng)換(huan)示教(jiao)器(qi)主板(ban)(ban)。
