Mayelana ne-hardware, ngokungafani nesisombululo se-welding ye-hybrid, lesi sixazululo silula futhi asidingi ama-lasers amabili noma ikhanda elikhethekile le-welding ye-hybrid. Idinga kuphela inhloko evamile yokushisela i-laser enamandla amakhulu (njengoba i-fiber optical eyodwa kuphela ikhipha i-Laser eyodwa yamaza, isakhiwo se-lens silula, akukho ukulungisa okudingekayo, nokulahlekelwa kwamandla kuphansi), okwenza kube lula ukulungisa iphutha nokugcina , futhi ukuzinza kwemishini kuthuthukiswa kakhulu.
Ngaphezu kwesistimu elula yesisombululo se-hardware nokuhlangabezana nezidingo zenqubo yokushisela ngesivinini esiphezulu sekhava yebhethri ephezulu, lesi sixazululo sinezinye izinzuzo ekusetshenzisweni kwenqubo.
Esivivinyweni, sishisele ikhava engaphezulu yebhethri ngesivinini esikhulu esingu-300mm/s, futhi sisazuza imiphumela emihle yokwakha umthungo wokushisela. Ngaphezu kwalokho, kumagobolondo anobukhulu obuhlukile bodonga obungu-0.4, 0.6, no-0.8mm, kuphela Ngokulungisa imodi yokuphuma kwe-laser, ukushisela okuhle kungenziwa. Kodwa-ke, ngezixazululo zokushisela i-laser hybrid welding we-wavelength ekabili, kuyadingeka ukuthi uguqule ukucushwa kwe-optical kwekhanda lokushisela noma i-laser, okuzoletha izindleko ezinkulu zemishini kanye nezindleko zesikhathi sokulungisa iphutha.
Ngakho-ke, indawo ye-point-ringlaser weldingIsixazululo asikwazi ukuzuza kuphela i-ultra-high-speed top cover welding ku-300mm/s futhi sithuthukise ukusebenza kahle kokukhiqiza kwamabhethri amandla. Ezinkampanini ezikhiqiza amabhethri ezidinga ukushintshwa kwamamodeli kaningi, lesi sixazululo singaphinde sithuthukise kakhulu ikhwalithi yemishini nemikhiqizo. ukuhambisana, ukunciphisa ukuguqulwa kwemodeli kanye nesikhathi sokulungisa iphutha.
Ukubukeka kokushisela kwekhava yebhethri ephezulu enogqinsi oluyi-0.4mm (isivinini sokushisela 300mm/s)
Ukubukeka kokushisela kwekhava yebhethri ephezulu enobukhulu obungu-0.6mm (isivinini sokushisela 300mm/s)
Ukungena Kwe-Corona Laser Weld Ye-Thin-Wall Cell Welding - Amakhono Enqubo
Ngaphezu kwe-laser ye-Corona okukhulunywe ngayo ngenhla, ama-laser e-AMB namalaser e-ARM anezici ezifanayo zokuphuma kwe-optical futhi angasetshenziswa ukuxazulula izinkinga ezinjengokuthuthukisa i-laser weld spatter, ukuthuthukisa ikhwalithi ye-weld surface, kanye nokwenza ngcono ukusimama kokushisela ngesivinini esikhulu.
4. Isifinyezo
Izixazululo ezihlukahlukene ezishiwo ngenhla zonke zisetshenziswa ekukhiqizeni kwangempela yizinkampani ezikhiqiza ibhethri ye-lithium yasekhaya neyangaphandle. Ngenxa yesikhathi esihlukene sokukhiqiza kanye nezizinda ezihlukene zobuchwepheshe, izixazululo zezinqubo ezahlukene zisetshenziswa kakhulu embonini, kodwa izinkampani zinezidingo eziphakeme zokusebenza kahle kanye nekhwalithi. Ithuthuka njalo, futhi ubuchwepheshe obusha obengeziwe buzosetshenziswa maduze izinkampani ezihamba phambili kwezobuchwepheshe.
Imboni yebhethri yamandla entsha yaseShayina iqale sekudlule isikhathi futhi isithuthuke ngokushesha iqhutshwa izinqubomgomo zikazwelonke. Ubuchwepheshe obuhlobene buqhubekile nokuthuthuka ngemizamo ehlanganyelwe yawo wonke uchungechunge lwezimboni, futhi buye bafinyeza ngokuphelele igebe nezinkampani zamazwe ngamazwe ezivelele. Njengomkhiqizi wemishini yebhethri ye-lithium yasekhaya, i-Maven iphinde ihlole izindawo zayo ezizuzisayo, isiza ukuthuthukiswa okuphindaphindiwe kwemishini yokupakisha ibhethri, futhi inikeze izixazululo ezingcono zokukhiqiza okuzenzakalelayo kwamaphakethe amamojula webhethri okugcina amandla amasha.
