Daim ntawv thov ntawm Laser Vuam nyob rau hauv Lithium roj teeb teb
Cov roj teeb lithium-ion tau siv dav hauv ntau yam khoom siv hluav taws xob (xws li xov tooj ntawm tes, khoos phis tawj khoos phis tawj, PDAs, cov koob yees duab digital thiab cov koob yees duab digital, thiab lwm yam) vim lawv lub zog tshwj xeeb, lub neej ntev, kev tso tawm me me, tsis muaj lub cim xeeb. thiab tsis muaj kuab paug. Raws li kev thauj mus los (tsheb thauj mus los, tsheb kauj vab hluav taws xob, tsheb hluav taws xob, thiab lwm yam), nws tau dhau los ua kev lag luam high-tech txhawb nqa los ntawm kuv lub teb chaws lub zog.
Cov roj teeb fais fab hais txog cov roj teeb uas siv hauv tsheb fais fab. Piv nrog cov roj teeb me me (xws li lub xov tooj ntawm tes, lub khoos phis tawj lub khoos phis tawj, thiab lwm yam), lawv muaj peev xwm loj dua thiab tso zis hluav taws xob thiab tuaj yeem siv rau hauv lub tsheb fais fab tsav tsheb thiab cov khoom siv hluav taws xob loj loj. ntawm cov roj teeb theem nrab. Muaj ntau cov txheej txheem tsim khoom rau cov roj teeb lithium-ion lossis roj teeb pob, ntawm cov uas muaj ntau txheej txheem, xws li tawg-pov thawj valve sealing vuam, tab welding, mos kev sib txuas vuam, kev ruaj ntseg kaus mom hlau qhov chaw vuam, roj teeb rooj sib khi vuam, module thiab PACK vuam. Laser vuam yog cov txheej txheem zoo tshaj plaws. Cov ntaub ntawv siv rau vuam ntawm cov roj teeb fais fab feem ntau suav nrog cov tooj liab ntshiab, aluminium, aluminium alloys, stainless hlau, thiab lwm yam.
1. Roj teeb tawg-pov thawj valve vuam
Lub foob pob hluav taws ntawm lub roj teeb yog lub cev nyias-walled valve lub cev ntawm lub roj teeb sealing phaj. Thaum lub siab sab hauv ntawm lub roj teeb ntau tshaj li qhov teev tseg, qhov tawg-pov thawj valve lub cev ruptures los tiv thaiv lub roj teeb ntawm bursting. Qhov kev nyab xeeb valve muaj cov qauv ingenious, thiab cov txheej txheem no yuav tsum nruj heev rau cov txheej txheem laser vuam. Ua ntej nruam laser vuam siv, mem tes laser vuam siv los vuam roj teeb tawg-pov thawj li qub. Nruam sealing vuam tau tiav los ntawm kev sib tshooj thiab kev pab cuam ntawm cov pob qij txha. Txawm li cas los xij, qhov kev ua haujlwm vuam tau qis thiab qhov kev sib khi ua haujlwm tsis zoo. Nruam laser welding tuaj yeem ua tiav high-speed thiab high-zoo vuam, thiab vuam stability, vuam efficiency thiab yield tuaj yeem lav.
2. Roj teeb tab welding
Cov tabs feem ntau muab faib ua peb yam khoom. Qhov zoo electrode ntawm lub roj teeb siv cov khoom siv txhuas (Al) thiab cov electrode tsis zoo siv cov khoom siv nickel (Ni) lossis tooj liab-plated nickel (Ni-Cu) cov khoom. Hauv kev tsim cov txheej txheem ntawm cov roj teeb fais fab, ib qho ntawm cov kauj ruam yog los txuas cov roj teeb tab thiab cov ncej ua ke. Nyob rau hauv kev tsim cov roj teeb theem nrab, nws yuav tsum tau welded nrog lwm yam txhuas kev ruaj ntseg valve. Vuam yuav tsum tsis yog tsuas yog ua kom ntseeg tau qhov kev sib txuas ntawm lub tab thiab tus ncej, tab sis kuj yuav tsum tau cov vuam kom du thiab zoo nkauj.
3. Roj teeb ncej nrog qhov chaw vuam
Cov ntaub ntawv siv rau roj teeb ncej strips muaj xws li ntshiab txhuas strips, nickel strips, aluminium-nickel composite strips, thiab ib tug me me ntawm tooj liab strips. Lub vuam ntawm cov roj teeb ncej strips feem ntau siv cov tshuab pulse vuam tshuab. Nrog qhov tshwm sim ntawm IPG's QCW quasi-nruam laser, nws kuj tau siv dav hauv roj teeb ncej sawb vuam. Nyob rau tib lub sijhawm, vim nws cov nqaj zoo, qhov chaw vuam tuaj yeem me me heev. , uas muaj qhov tshwj xeeb zoo hauv kev cuam tshuam cov vuam ntawm high-reflectivity aluminium strips, tooj liab strips thiab nqaim-band roj teeb ncej strips (ncej sawb dav hauv qab 1.5mm).
4. Sealing thiab vuam ntawm lub hwj chim roj teeb plhaub thiab npog phaj
Cov ntaub ntawv plhaub ntawm cov roj teeb muaj xws li aluminium alloy thiab stainless hlau. Ntawm lawv, aluminium alloy yog siv ntau tshaj plaws, feem ntau yog 3003 aluminium alloy, thiab ob peb siv ntshiab txhuas. Stainless hlau yog cov khoom siv nrog qhov zoo tshaj plaws laser weldability, tshwj xeeb tshaj yog 304 stainless hlau. Txawm hais tias siv mem tes los yog laser txuas ntxiv, welds nrog cov tsos zoo thiab kev ua tau zoo tuaj yeem tau txais.
Lub laser vuam kev ua tau zoo ntawm txhuas thiab txhuas alloys txawv me ntsis nyob ntawm seb txoj kev siv vuam siv. Tsuas yog cov ntshiab txhuas thiab 3 series txhuas alloys, tsis muaj teeb meem nrog mem tes vuam lossis txuas txuas ntxiv. Rau lwm cov series ntawm txhuas alloys, nruam laser vuam yog qhov kev xaiv zoo tshaj plaws los txo cov tawg rhiab heev. Nyob rau tib lub sijhawm, xaiv lub laser nrog lub zog tsim nyog raws li lub thickness ntawm lub hwj chim roj teeb rooj plaub. Feem ntau, thaum cov ntaub ntawv tuab tsawg dua 1 hli, koj tuaj yeem txiav txim siab siv ib hom laser hauv 1000W. Yog hais tias lub thickness yog ntau tshaj 1 hli, koj yuav tsum tau siv ib hom los yog ntau hom laser nrog lub hwj chim ntawm ntau tshaj 1000W.
Cov roj teeb uas muaj peev xwm me me feem ntau siv cov plhaub nyias nyias (thickness yog li 0.25mm), thiab qee qhov xws li 18650 siv cov plhaub hlau. Vim lub thickness ntawm lub casing, qis zog lasers feem ntau yog siv rau vuam hom roj teeb. Siv cov laser txuas txuas mus rau vuam nyias-plhaub lithium roj teeb, qhov ua tau zoo tuaj yeem nce los ntawm 5 mus rau 10 zaug, thiab cov tsos thiab sealing zoo dua. Yog li ntawd, muaj ib qho kev hloov maj mam hloov cov lasers hauv daim ntawv thov no.
5. Fais fab roj teeb module thiab pob vuam
Cov koob thiab kev sib txuas ntawm cov roj teeb hluav taws xob feem ntau ua tiav los ntawm kev sib txuas ntawm cov khoom txuas mus rau ib lub roj teeb. Cov ntaub ntawv ntawm qhov zoo thiab tsis zoo electrodes yog txawv, feem ntau tooj liab thiab txhuas. Txij li thaum tooj liab thiab txhuas ua ib qho nkig tom qab laser vuam, lawv tsis tuaj yeem ua tau raws li cov kev cai siv, ntxiv rau ultrasonic vuam, tooj liab thiab tooj liab, txhuas thiab txhuas feem ntau yog laser welded. Nyob rau tib lub sij hawm, vim hais tias ob qho tib si tooj liab thiab txhuas ua cua sov sai heev thiab muaj siab heev laser reflectivity, thiab lub thickness ntawm cov txuas yog kuj loj, ib tug siab zog laser yuav tsum tau mus cuag vuam.
Cov yam ntxwv ntawm laser vuam lithium roj teeb
Los ntawm kev tsim cov roj teeb lithium mus rau kev sib dhos ntawm cov roj teeb pob, vuam yog ib qho tseem ceeb ntawm kev tsim khoom. Cov conductivity, lub zog, huab cua nruj, hlau qaug zog thiab corrosion kuj ntawm lithium roj teeb yog cov roj teeb vuam zoo ntsuas cov qauv. . Kev xaiv cov txheej txheem vuam thiab cov txheej txheem vuam yuav cuam tshuam ncaj qha rau tus nqi, qhov zoo, kev nyab xeeb thiab sib xws ntawm lub roj teeb. Laser vuam tau dhau los ua qhov kev daws teeb meem zoo tshaj plaws rau ntau txoj haujlwm vuam vim nws qhov zoo xws li kev nyab xeeb thiab txhim khu kev qha vuam, precision tshuab, thiab kev tiv thaiv ib puag ncig.
