Kwizinto zanamhlanje eziphezulu-ezisetyenziswayo{1}}ukusuka kwizithuthi zamandla amatsha (NEVs) ukuya kwiinkqubo zamandla kushishino{2}}iibhasi zebhasi eziguquguqukayo azinakuphinda zifumaneke endaweni yazo. Ezi "conductor zamandla aguquguqukayo" zixazulula indawo yentlungu yoxhulumaniso oluqinileyo, ukulungelelanisa kwiindawo eziqinileyo kunye ne-vibration yokufunxa ngelixa uqinisekisa ukuhanjiswa okusebenzayo ngoku. Kodwa nanku umbuzo obalulekileyo: Uzivelisa njani iibhasi zebhasi eziguquguqukayo ezomeleleyo, eziqhubayo, kwaye zinyanisekile kwindalo yazo "eguquguqukayo"? Impendulo ilele kubuchwephesha bokuwelda obuphambili{5}}kwayeHAIFEI Flexible Busbar Welding Machine(isisombululo esikhethekileyo se-polymer diffusion welding) iyilelwe ukuba ibe nobuchule kule nkqubo, ikunceda wenze phezulu{0}}iibhasi zeebhasi ezibhetyebhetye kuzo zonke iimfuno zeshishini.
Yintoni i-Copper Flexible Busbar, kunjalo?
Phambi kokuntywila kwi welding, makhe sicacise: Yintoni kanye kanye i-copper flexible busbar (ehlala ibizwa ngokuba "yicopper flexible connection," "copper busbar expansion joint," okanye "soft copper bar" kwijargon yoshishino)?
Ukubeka ngokulula, ngumlingani oguquguqukayo kwiibhasi zebhasi eziqinileyo. Ngelixa iibhasi zebhasi eziqinileyo zenziwe ngamashiti ekopolo aqinileyo enkonkxiweyo ngokunyathela kunye nokugoba (eqinile, ilungele ufakelo olusisigxina),iibhasi zebhasi eziguquguqukayo zobheduziyilwe ngokulayita iifoyile ezininzi zobhedu ezicekethekileyo, emva koko zidibanise iziphelo zombini zisebenzisa-ubushushu obuphezulu,{1}}inkqubo yoxinzelelo oluphezulu. Isiphumo? I-conductor egcina ukuhanjiswa okugqwesileyo kobhedukwayeinikeza ubhetyebhetye olungahambelaniyo-olukwazi ukujinga, ukujikelezisa, kunye nokugoba ngokuthanda ngaphandle kokuqhekeka. Oku kuyenza igqibelele usetyenziso apho intshukumo okanye uyilo olungaqhelekanga luqhelekile, njengeepakethe zebhetri zeNEV okanye isixhobo sokutshintsha kweshishini.
Isitshixo ekusebenzeni kwayo? Inkqubo ye-welding. Ukuba iifoyile zobhedu azibophelwanga ngokufanelekileyo, i-busbar iya kubandezeleka ngenxa yokuchasana okuphezulu, amajoyina abuthathaka, okanye ukulahlekelwa ukuguquguquka. Iindlela zokuwelda zesiNtu (ezifana neendawo zokuwelda) zihlala zisilela apha-zinokongeza iintsimbi zokugcwalisa ezicutha ukuhanjiswa okanye zonakalise iifoyile ezibhityileyo. Yiyo loo nto i-polymer diffusion welding ingumgangatho wegolide wecopper flexible busbar-kwaye ngobaHAIFEI Flexible Busbar Welding Machinengumdlalo{0}}umtshintshi.
Kutheni iWelding yesiNtu isilela kwiiBusbars zeCopper Flexible
Masicalule imiceli mngeni yokwenza iibhasi zebhasi eziguquguqukayo{0}kwaye kutheni abaweldi abaqhelekileyo bengakwazi ukuqhubeka:
- I-Foil Lamination Consistency: Iibhasi zebhasi eziguquguqukayo ze-Copper zisebenzisa i-10-50 ye-foil yobhedu encinci (ngamanye amaxesha incinci njenge-0.1mm). Ukuwelda ezi maleko kufuna ubushushu obufanayo kunye noxinzelelo{4}}ubushushu obuninzi kakhulu, kwaye ifoyile iyanyibilika; incinci kakhulu, kwaye iileya azidibanisi. Abashiseli beendawo zemveli bayasokola kule balance, ekhokelela kumalungu angalinganiyo.
- UkuGcinwa kokuGcina: Inqaku elipheleleyo lebhasi yebhasi "eguquguqukayo" kukugoba. Ukuba i-weld iqinile kakhulu (umzekelo, ukusuka kwi-brazing filler), i-busbar iyakuqhekeka phantsi kwe-vibration{3}}eqhelekileyo kwii-NEVs okanye koomatshini boshishino.
- Ukuqhuba: Ukuxhathisa okuphantsi kweCopper yeyona asethi yayo inkulu. Ukongeza iintsimbi zokugcwalisa (ezifana nesilivere-ialloyi zobhedu) kuphakamisa ukuxhathisa, okukhokelela ekulahlekeni kwamandla kunye nokwanda kobushushu{2}}imingcipheko emibini ephezulu{3}}kwizicelo zangoku ezifana neebhasi zamandla ebhetri ezibhetyebhetye.
- Ukuqina: I-Copper i-oxidizes ngokulula kumaqondo aphezulu. I-weld engalunganga enemigangatho ye-oxide iya kugqwala ngokuhamba kwexesha, icuthe ubomi bebhasi.
Le miba ayizongxaki zobulunga kuphela{0}yimingcipheko yokhuseleko nokusebenza kakuhle. Umzekelo, i-copper flexible busbar engalunganga kwipakethi yebhetri ye-NEV inokubangela ukulahleka kwamandla okanye nokutshisa kakhulu. KulaphoHAIFEI Flexible Busbar Welding Machineamanyathelo: isebenzisa i-polymer diffusion welding ukuphelisa zonke ezi ndawo zentlungu.
Indlela i-HAIFEI Flexible Busbar Welding Machine Uhambisa ngayo iiBusbars eziGuquguqukayo zeCopper
Umatshini we-HAIFEI ayingo "welder"{0}}sisisombululo esikhethekileyo esenzelwe iimfuno ezizodwa zeebhasi eziguquguqukayo zobhedu. Nantsi indlela esebenza ngayo, kwaye kutheni iphumelela ukodlula ukhuphiswano:
1. I-Polymer Diffusion Welding: iMfihlo eYomelele, i-Flexible Joints
- Embindini womatshini we-HAIFEIi-polymer diffusion welding-inkqubo eqinileyo-ebophelela iifoyile zobhedu ngaphandle kweentsimbi zokuzalisa okanye ukunyibilika. Nantsi isayensi:
- Umatshini ubeka iifoyile zobhedu kwaye usebenzisa ubushushu obuchanekileyo (50-70% yendawo yokunyibilika kobhedu) kunye noxinzelelo.
- Phantsi kwezi meko, iimolekyuli zobhedu kujongano lwefoyile ziyasasazeka enye kwenye, zenza iqhina elingenamthungo lesinyithi{0}}kanye njengokuba iifoyile "zidityanisiwe" zibe nye.
- Akukho nto yokuzalisa ithetha ukuba i-conductivity ye-joint ihambelana nesiseko sobhedu, kwaye akukho kunyibilika kugcina i-foil encinci, i-flexible structure.
- Isiphumo? Ibhasi yebhasi ebhetyebhetye egoba, ijija, kwaye ijike ngokukhululekileyo-kanye into efunekayo kwiipakethi zebhetri zeNEV okanye ufakelo oluluqilima lwemizi-mveliso.
2. Igqibelele kwiLap Welding yeeBusbars zeKopha eziQimileyo nezithambileyo
- Usetyenziso oluninzi lufuna ukuqhagamshelwaiibhasi zobhedu ezinzima nezithambileyo(umzekelo, iibhasi zebhasi eziqinileyo ukusuka kumbane ukuya kwiibhasi eziguqukayo kwibhetri). Le "lap welding" iyakhohlisa{3}}ikopolo eqinileyo ingqindilili kwaye iqinile, ngelixa ikopolo ethambileyo ibhityile kwaye iyabhetyebhetye. Umatshini we-HAIFEI ulungelelanisa ubushushu kunye noxinzelelo ngokuguquguqukayo: usebenzisa ubushushu obaneleyo ukubopha ezi zimbini kodwa akwanelanga ukonakalisa iifoyile zobhedu oluthambileyo. Isiphumo yilap joint eyomeleleyo (emelana nokungcangcazela) kunye ne-conductive (akukho lahleko yamandla){6}}elungele iinkqubo zokuhambisa amandla.
3. Yenzelwe iBattery Flexible Busbars
- I-NEVs zezona ntengiso zinkulu kwiibhasi zebhasi eziguquguqukayo, kwaye umatshini we-HAIFEI wakhelwe ukuhlangabezana nemigangatho engqongqo. Iibhasi zebhasi eziguquguqukayo zamandla kufuneka:
- Dlulisa imisinga ephezulu (ukuya kuthi ga kwi-1000A) ngaphandle kokutshisa.
- Ukumelana nokutshintsha kobushushu (-40℃ukuya kwi-85 degree) kunye nokungcangcazela.
- Yiba bhityile ngokwaneleyo ukuba ungene kwiipakethi zebhetri ezixineneyo.
Umatshini we-HAIFEI uhambisa kuwo onke amanani:
- Igumbi layo lokufunxa linqanda i-oxidation ngexesha le-welding, iqinisekisa ukuxhathisa{0}}ixesha elide lokutya.
- Ulawulo lwedijithali lugcina ukuchaneka kweqondo lokushisa ngaphakathi kwe-± 5 idigri, ngoko ke yonke ibha yebhasi isebenza ngokungaguqukiyo.
- Iphatha iifoyile ezibhityileyo (0.05mm–0.2mm) ngokulula, ivelisa iibhasi ezilingana nolona yilo luncinci lwebhetri.
4. Ngokufanelekileyo kwiMveliso yeMisa
- Nokuba wenza i-100 okanye i-10,000 yeebhasi eziguquguqukayo zobhedu ngosuku, umatshini we-HAIFEI uyaqhubeka. Ibandakanya:
- Ukupakishwa kwefoyile ngokuzenzekelayo kunye nokutya: Yehlisa impazamo yomntu kwaye ikhawulezise ixesha lokulungiselela.
- Ixesha lokwenyani{0}}lokujongwa komgangatho: Izivamvo zijonga ii-bonding ezingalinganiyo okanye i-oxide layers, zala iziphene kwangoko.
- Amaxesha omjikelezo okhawulezayo: I-weld enye ithatha imizuzu emi-2-5 (kuxhomekeke kubungakanani bebhasi), ngokukhawuleza kakhulu kune-welding ye-diffusion manual.
- Kubavelisi, oku kuthetha iindleko eziphantsi, amaxesha okukhokela ngokukhawuleza, kunye nokukwazi ukulinganisa i-NEV okanye imfuno yoshishino.
