Izinzuzo nokugqamisa: Inqubo yokulinganisa umthamo ingahlola ngokunembile amabhethri anekhwalithi engahambisani futhi iqinisekise ukuthi ibhethri ngalinye elifinyelela kubathengi lingumkhiqizo wekhwalithi ephezulu ohlolwe ngokuqinile. Ukufanisa amandla kungathuthukisa umphumela wokusetshenziswa kwenhlanganisela yamabhethri amaningi futhi kuthuthukise ukusebenza okuphelele. Ukulinganisa i-voltage kungaqinisekisa ukusebenza nempilo yamaphakethe ebhethri ye-lithium. Ngokuhlela umthamo, ukungahambi kahle ohlelweni lokukhiqiza kungatholwa ukugwema izingozi ezingaba khona zokuphepha futhi kuthuthukiswe ukushajwa nokukhipha ukusebenza kahle kwebhethri.
- Inqubo yokugcina
Ukuhlolwa kokubukeka, ukubhala amakhodi, ukuskena ukuhlolwa kwesibili, ukupakishwa, nokugcinwa kwempahla eqediwe. Inqubo yokukhiqiza amabhethri e-lithium iyinkimbinkimbi futhi icophelela. Yonke inqubo ihlobene nokusebenza kanye nekhwalithi yebhethri. Kusukela ekuxutshweni kwezinto zokusetshenziswa kuye ekuhlolweni kokugcina komkhiqizo, yonke isixhumanisi ihlanganisa amandla obuchwepheshe nomoya wezingcweti.
Njengomholi embonini, i-Yixinfeng ibilokhu izibophezele ekuhlinzekeni ngemishini ethuthukisiwe nezixazululo zokukhiqiza ibhethri ye-lithium. Imishini yethu emisha ibonise ukusebenza okuhle kakhulu kanye nezinzuzo kuzo zonke izici zokukhiqiza ibhethri ye-lithium. Kungakhathaliseki ukuthi isezingeni eliphezulu kanye nemishini yokuhlanganisa enembayo, okokusebenza okusongayo okuzinzile futhi okuthembekile, noma okokusebenza kokubona okuhlakaniphile, kungaletha ukusebenza kahle okuphezulu, ikhwalithi engcono nokuncintisana okunamandla ekukhiqizeni kwakho ibhethri le-lithium. Ukukhetha i-Yixinfeng ukukhetha ikhwalithi nokusha. Masihlanganyele izandla ukuze sakhe ikusasa elingcono lokwenziwa kwebhethri ye-lithium.
Umshini wokusika ukufa oguquguqukayo we-laser (okhethekile wamablade namabhethri astakiwe)
Umshini wokusika ukufa oguquguqukayo we-laser iyisisetshenziswa esisebenzisa ubuchwepheshe be-laser ukucubungula ukufa. Ikhiqiza amandla ashisayo aphezulu ngokugxila kwe-laser beam ukusika izinto. Inekhwalithi ephezulu, ukunemba okuphezulu, ukusebenza kahle okuphezulu, kulula ukuyisebenzisa, futhi inokuphepha okuphezulu. Ingashintshwa ngokhiye owodwa futhi inezindleko eziphansi.
Imishini yokwelapha ye-laser pole piece
Ubuchwepheshe bokubhala nge-laser bungathuthukisa izinga lokugcinwa komjikelezo webhethri futhi kunciphise ukumelana kwangaphakathi kwebhethri, kukhuphule amandla ngeyunithi ngayinye yendawo yebhethri, futhi kuthuthukise ukuminyana kwamandla nezinga.
I-laser die-cutting winding and flattening umshini odidiyelwe (isilinda esikhulu φ18650 - φ60140)
I-Yixinfeng ithuthukisa ngokuzimela uhlelo lokusika i-laser olunamandla aphelele e-POS alandela i-algorithm. Isivinini sokukhiqiza esizinzile ngu-120m/min. Umshini odidiyelwe ungalungiswa ngokusika i-die-cutting futhi uyahambisana ne-AB battery cell winding. Inobubanzi obubanzi bokuhambisana. Lesi sisetshenziswa singenza wonke amamodeli amaseli ebhethri afana ne-18/21/32/46/50/60.
Ukuqoqwa kwe-Ear Scrap kanye Nomshini Ohlanganisiwe Ohlanganisiwe
Le khabhinethi yemfucuza ingumshini odidiyelwe wesitoreji kanye ne-extrusion owenziwe yinkampani yethu ngokukhethekile ukuqoqwa nokucindezelwa kwemfucuza ekhiqizwa ngesikhathi sokusika noma inqubo yokusika yezinto ezinhle nezimbi ze-electrode zamabhethri e-lithium. Inezici zokusebenza okulula, ukukhishwa kwemfucuza okulula, indawo encane yaphansi, ukusebenza okuzinzile, nomsindo ophansi. Phakathi nenqubo yokukhiqiza amabhethri e-lithium, inani elithile le-ear scrap lizokwenziwa. Uma ingeke iqoqwe futhi isetshenzwe ngempumelelo, ingase ithinte ukuhlanzeka kwendawo yokukhiqiza futhi ingase ibangele ngisho nezingozi zokuphepha. Ngokusebenzisa iqoqo le-ear scrap kanye nomshini odidiyelwe wokuhlanganisa, imfucuza emgqeni wokukhiqiza ingahlanzwa ngesikhathi ukuze kugcinwe indawo yokukhiqiza ihlanzekile futhi ihlanzekile, okulungele ukuthuthukisa ukuphepha nokuzinza kokukhiqiza. Ngaphezu kwalokho, indlela esebenza kahle yokuqoqa imfucuza inganciphisa izindleko zabasebenzi kanye nezindleko zesikhathi. Ngokombono wokugaywa kabusha kwensiza, izindlebe ezihlangene zilungele ukucutshungulwa okulandelayo kanye nokusetshenziswa kabusha, okulungele ukugaywa kabusha kwezisetshenziswa futhi okuhambisana nomqondo wentuthuko esimeme.
Umshini Wokuhlanza Ozenzakalelayo Wesici
Isici sokuhlunga umshini wokuhlanza ngokuzenzakalela siyidivayisi esetshenziselwa ukuhlanza izakhi zokuhlunga. Ngokuvamile isebenzisa ubuchwepheshe obuhlukahlukene kanye nemisebenzi ukuze kuzuzwe imiphumela yokuhlanza ephumelelayo nephelele. Isici sokuhlunga umshini wokuhlanza okuzenzakalelayo unezici zokusebenza okulula nokuhlanza okuphumelelayo, okunganciphisa izindleko nokwandisa impilo yesevisi yezinto zokuhlunga. Idlala indima ebalulekile ekugcineni ukusebenza kahle kwemishini yokukhiqiza ibhethri ye-lithium, ukuqinisekisa ikhwalithi yomkhiqizo, ukulawula izindleko, nokukhuthaza intuthuko esimeme yomkhakha.
Umshini Wokususa Uthuli Wokukhiqiza I-Chip Eyinkulungwane
Lo mshini usebenzisa indlela yokuhlanza uthuli eku-inthanethi. Ngokugeleza komoya komjovo wejubane eliphezulu kanye nomfutho ophezulu ukuze kukhiqizwe ingcindezi kanye nokudlidliza okuncane ukuze kufezwe injongo yokukhipha uthuli, futhi kuyaphinda futhi kuzungeza ngokuqhubekayo. Umshini wokukhipha uthuli wokukhiqiza i-chip yebanga eliyinkulungwane uhlinzeka ngendawo ehlanzekile, ephephile, futhi ezinzile yokukhiqiza amabhethri e-lithium ngokulawula uthuli, futhi udlala indima ebalulekile yokusekela ekuthuthukiseni ikhwalithi, ukusebenza, nokusebenza kahle kokukhiqizwa kwamabhethri e-lithium.
