Cov roj teeb hluav taws xob tsim los rau cov tsheb fais fab (EVs) thiab loj- cov khoom siv hluav taws xob hauv xov tooj ntawm tes yuav tsum muaj peev xwm tshwj xeeb, cov khoom siv hluav taws xob, thiab kev ua haujlwm zoo. Hauv lithium-ion roj teeb sib dhos, laser vuam tau ua pov thawj tias yog txoj kev ua tau zoo tshaj plaws, meej, thiab txhim khu kev qha. Los ntawm kev sib khi ntawm tes mus rau pob kev sib koom ua ke, laser vuam ncaj qha txiav txim siab lub roj teeb kev nyab xeeb, kev coj ua, thiab kev ua neej nyob.
Cov lus qhia dav dav no rhuav tshem cov kev siv laser vuam tseem ceeb hla cov txheej txheem tsim roj teeb thiab qhia txog cov khoom siv zoo tagnrho rau txhua theem.
Sab saum toj 5 Laser Vuam Daim Ntawv Thov hauv Roj Teeb Sib Tham
1. Roj teeb tawg- Pov thawj Valve Sealing
Lub foob pob tawg- pov thawj valve yog ib qho tseem ceeb nyias-walled mechanism ntawm lub roj teeb npog phaj. Thaum lub siab sab hauv, lub valve ruptures yam xyuam xim los tiv thaiv thermal runaway los yog tawg.
Txoj Kev Sib Tw:Cov txheej txheem no xav tau huab cua tiag tiag- nruj thiab xoom kub distortion ntawm ultra- cov phab ntsa nyias.
Lub Evolution:Ib txwm siv lub tshuab laser vuam tau ua tiav kev sib khi ntawm qhov sib tshooj, uas ua rau txo qis kev ua haujlwm thiab sub- qhov zoo sib xws. Niaj hnub no, nruam nthwv dej (CW) laser welding muab siab -ceev, zoo li seams, drastic txhim kho foob kev ntseeg siab thiab ntau lawm yield.
2. Roj teeb Tab & Lug Vuam
Roj teeb tabs (lugs) txuas cov electrodes sab hauv mus rau sab nraud terminals. Feem ntau, lub davhlau ya nyob twg zoo siv Aluminium (Al) thaum lub davhlau ya nyob twg tsis zoo siv Nickel (Ni) lossis Nickel-plated Copper (Ni-Cu).
Txoj Kev Sib Tw:Vuam cov ntaub ntawv zoo sib xws, cov khoom siv sib txawv no yuav tsum muaj kev sib raug zoo ntawm cov khoom siv sib txuas thiab cov hluav taws xob tsawg kawg nkaus yam tsis muaj kev puas tsuaj rau lub hauv paus cais. Nruam laser welding kom du, txhim khu kev qha, thiab zoo nkauj zoo nkauj pob qij txha.
3. Terminal Ncej Band Spot Vuam
Kev sib txuas cov electrode strips (ntshiab aluminium, npib tsib xee, los yog cov strips sib xyaw) feem ntau cuam tshuam nrog kev nqaim nqaim, siab -reflector bands (feem ntau tsawg dua 1.5mm dav).
Kev daws:Thaum cov lasers pulsed muaj keeb kwm tshwm sim, Quasi -Nruam Wave (QCW) fiber ntau lasers tau dhau los ua qauv kev lag luam. Lawv qhov tshwj xeeb nqaj zoo thiab ultra- qhov chaw focal me me muab qhov tshwj xeeb zoo thaum cuam tshuam nrog siab -reflectivity aluminium lossis tooj liab hauv qhov chaw txwv tsis pub muaj ntau.
4. Case-rau-Cov Khoom Siv Sealing (Alloy Sealing)
Roj teeb enclosures feem ntau yog ua los ntawm 3003 txhuas alloy, ntshiab txhuas, los yog 304 stainless hlau.
Stainless hlau muaj zoo weldability nyob rau hauv ob qho tib si pulsed thiab nruam lasers.
Rau aluminium alloys, nruam fiber ntau lasers yog qhov kev xaiv tseem ceeb. Lawv suppress weld crack rhiab heev thiab xa cov nkag mus tau yooj yim. Rau nyias aluminium shells (~ 0.25mm), siv cov laser txuas txuas ntxiv es tsis txhob siv cov tshuab pulsed boosts ntau lawm efficiency los ntawm 5 mus rau 10 zaug thaum muab kev zoo nkauj zoo nkauj thiab hermetic sealing.
5. Roj teeb Module & Pob kev koom ua ke
Txhawm rau ua tiav qhov xav tau qhov hluav taws xob thiab lub peev xwm, cov hlwb ntawm ib tus neeg txuas nrog hauv cov koob lossis sib npaug siv cov busbars (txuas daim).
Siab -Power Xav Tau:Busbars yog thicker thiab hloov tshav kub ceev heev. Vim muaj kev cuam tshuam zoo ntawm tooj liab thiab txhuas, siab - lub zog fiber ntau lasers yog qhov yuav tsum tau ua kom muaj kev nkag mus tob, txhim khu kev qha lub zog, thiab cov hluav taws xob tsawg tsawg thoob plaws tag nrho cov roj teeb.
Pom zoo Lithium roj teeb Laser vuam khoom
Yuav kom ua tau raws li cov qauv kev lag luam nruj no, Wuhan King's Laser muab kev ua haujlwm zoo, siab -kev ua haujlwm laser tshuab tsim rau cov roj teeb uas siv hluav taws xob ntau lawm.
Solution A: QCW Fiber Laser Vuam Tshuab
Qhov zoo tshaj plaws rau:Roj teeb tab/lug vuam, ncej band qhov chaw vuam, thiab nqaim - dav precision Cheebtsam.
Core Advantage:Nta ntawm qhov chaw tsom qhov kab uas tsuas yog 1/3 ntawm ib txwm YAG lasers. Nws muab lub zog siab tshaj plaws nrog cov khoom siv hluav taws xob tsawg kawg nkaus, ua rau nws zoo meej rau siab -reflector hlau (tooj liab / aluminium).
Solution B: Tsis Siv Neeg Nruam Fiber Laser Vuam Tshuab
Qhov zoo tshaj plaws rau:Case-rau- npog sealing, tawg- pov thawj valve nruam vuam, thiab pob busbar kev koom ua ke.
Core Advantage:Yooj yim nkag mus rau cov hlau ntau dua 2 hli tuab. Nruab nrog ib tug tom ntej - tiam fiber ntau laser qhov chaw thiab ib tug advanced wobble vuam taub hau, nws ho widens lub vuam seam kam rau ua thiab tshem tawm porosity.
Vim li cas thiaj xaiv Laser Vuam rau Lithium roj teeb?
Los ntawm kev tsim ib lub xov tooj ntawm tes mus rau hnyav - lub luag haujlwm roj teeb pob, vuam zoo txiav txim siab txhua yam. Conductivity, tensile zog, hermetic sealing, hlau qaug zog, thiab corrosion kuj yog cov tseem ceeb benchmarks ntawm lub hwm roj teeb. Laser vuam tau universally dhau los ua tus qauv kub hauv EV roj teeb kab vim nws xa cov khoom tsis sib xws, kev siv ceev ceev, xoom hu rau degradation, thiab eco- tus phooj ywg hneev taw.
