Evolution tsom xam ntawm Aluminium npog phaj rau roj teeb laser vuam tshuab

Square Aluminum cover plate for batteries have become the mainstream technology route for lithium battery manufacturing due to their compact structure, strong impact resistance, high energy density, and large single cell capacity, and their market share remains stable. Laser welding yog ib qho ntawm cov txheej txheem tseem ceeb hauv kev tsim cov txheej txheem ntawm cov square aluminium plhaub roj teeb, dav siv hauv cov kev sib txuas tseem ceeb xws li kev sib txuas ntawm tes thiab npog phaj vuam, Lithium roj teeb sab saum toj caps sealing, thiab sealing ntsia hlau vuam.

Laser welding has become the preferred solution for sealing and welding Battery aluminum safety cover sets due to its high energy density, excellent power stability, high welding accuracy, and ease of automation integration. Nws ncaj qha txiav txim siab qhov sib khi, lub zog muaj zog, thiab kev nyab xeeb ntawm lub roj teeb.

Nrog rau qhov loj -scale expansion ntawm lithium roj teeb muaj peev xwm, lub sealing vuam ntawm lub hwj chim roj teeb npog phaj, raws li ntev thiab feem ntau lub sij hawm-siv qhov tseem ceeb weld, tau dhau los ua lub ntsiab tseem ceeb ntawm kev lag luam nyob rau hauv cov nqe lus ntawm vuam efficiency thiab zoo. Txoj kev loj hlob ntawm kev lag luam thev naus laus zis revolves nyob ib ncig ntawm kev txhim kho vuam ceev rau tooj liab thiab txhuas bimetal bipolar daim hlau, maj mam muab faib ua peb eras: 1.0 era (2015-2017, ceev<100mm/s), 2.0 era (2017-2018, speed 100-200mm/s), and 3.0 era (2019 present, speed 200-300mm/s). Technological iteration continues to promote the improvement of production efficiency and yield.

Nyob rau hauv cov theem thaum ntxov ntawm kev lag luam kev loj hlob, tsav los ntawm tshiab lub zog tsheb txoj cai, ntau lawm muaj peev xwm nthuav dav, tab sis cov txheej txheem tsim thiab cov cuab yeej tseem nyob rau hauv lawv cov me nyuam mos thiab cov℃ntawm automation kuj tsawg.

Nyob rau theem no, qhov vuam ceev ntawm Aluminium npog phaj rau cov roj teeb yog nyob rau hauv thaj tsam ntawm 50-100mm / s, sib xws rau kev tsim khoom ntawm li 6-10PPM. Cov txheej txheem cov cuab yeej siv feem ntau siv 1kW fiber ntau laser ua ke nrog cov pa vuam taub hau, tsav los ntawm servo platforms lossis linear motors. Vim lub vuam qeeb qeeb thiab lub sij hawm ntev thermal lub sij hawm ntawm lub hwj chim roj teeb npog phaj, lub pas dej molten muaj lub sij hawm txaus los ntws thiab solidify, thiab cov roj tiv thaiv yog txaus, ua rau nws yooj yim kom tau txais cov welds zoo nrog cov npoo du thiab zoo ib yam.

Cov qauv yooj yim, tus nqi qis, thiab kev ruaj ntseg zoo ntawm cov cuab yeej siv hauv lub sijhawm no tau tsim lub hauv paus rau kev txhim kho Prismatic lithium roj teeb hau vuam tshuab rau yav tom ntej. Tab sis nws cov kev txwv kuj tseem ceeb, thiab qhov qis - hom ceev yog qhov nyuaj rau kev hloov mus rau yav tom ntej muaj peev xwm ua kom muaj peev xwm nce ntxiv; Tsuas yog ua kom lub zog thiab nrawm nrawm tuaj yeem ua rau luv luv thermal cycles, khaus splashing ntawm lub pas dej ua ke, thiab nce porosity thiab voids.

Tau ntsib nrog kev loj hlob ntawm kev tsim muaj peev xwm thiab qhov kev thov kom nce ib kab ntau lawm, kev lag luam ceev ceev yuav tsum tau thawb lub Prismatic lithium roj teeb canopy vuam ceev mus rau 150-200mm / s, sib xws rau kev nce hauv kev tsim khoom rau 15-20PPM. Txhim kho lub tshuab tsav mus rau lub tshuab hluav taws xob linear kom ua tau raws li qhov xav tau ntawm kev kub ceev vuam rau saum lub hau.

Txhawm rau kom ntseeg tau qhov zoo ntawm Prismatic lithium roj teeb txuas ntxiv welds nyob rau hauv siab - vuam ceev, kev lag luam tab tom tshawb nrhiav cov cuab yeej siv nyob ib ncig ntawm peb qhov yuav tsum tau ua: vuam tsim, du nto, sib xws, thiab porosity tsawg. Nyob rau hauv thaum ntxov hnub, lub tswv yim ntawm multi laser composite welding tau saws, uas ua tiav ob qho tib si tob tob thiab dav vuam los ntawm cov synergistic nyhuv ntawm txawv wavelength lasers. Nrog rau kev loj hlob ntawm fiber ntau laser tshuab, cov tswv yim sib xyaw tau hloov zuj zus mus rau hauv coaxial tso zis ntawm fiber ntau laser + LD semiconductor laser, uas tuaj yeem ua tiav ruaj khov sab saum toj hau rau prismatic roj teeb ntawm tes vuam ntawm 200mm / s.

Tib lub sijhawm, siab - zaus viav vias laser vuam tshuab tau tshwm sim. Qhov kev daws teeb meem no tsuas yog xav tau ib lub laser fiber ntau thiab lub viav vias vuam lub taub hau, uas yog tsav los ntawm lub cev muaj zog los cuam tshuam lub lens thiab ua rau lub laser viav vias ntawm lub siab zaus raws li ib qho kev sib tw, tsim lub qhov tseem ceeb. Lub viav vias vuam tuaj yeem ua kom zoo rau lub pas dej molten, txhawb nqa cov pa khiav tawm, kho lub pinhole ntawm qhov chaw tawg, thiab tau txais cov qauv ntses tsis tu ncua Aluminium roj teeb npog vuam.

Nkag mus rau lub sijhawm hloov pauv kev lag luam, "kev txhim kho zoo, txo cov nqi, thiab kev ua haujlwm tau zoo" tau dhau los ua lub ntsiab lus tseem ceeb, thiab Aluminium roj teeb lub thawv npog vuam tshuab nrog ceev ntawm 300mm / s thiab siab dua tau dhau los ua kev tshawb fawb thiab kev loj hlob. Nyob rau theem no, thev naus laus zis breakthroughs revolves nyob ib ncig ntawm ob lub ntsiab lus qhia: npaum stability thiab system simplification.

Zuag qhia tag nrho, 3.0 era thev naus laus zis kev daws teeb meem sib xyaw ua ke ultra high speed Lithium-ion roj teeb npog daim hlau vuam, kev ruaj ntseg siab, thiab cov cuab yeej siv yooj yim, ntxiv kev txhawb nqa kev txhim kho ntawm lithium roj teeb kev lag luam. Muab kev txhawb nqa rau kev loj- nplai kev loj hlob ntawm kev lag luam, thiab xyuas kom meej tias lub hau npog sab saum toj tuav tswj kev ua haujlwm zoo hauv kev ua haujlwm siab - nrawm.

Yog tias koj yuav tsum kawm txog cov txheej txheem laser vuam txheej txheem, xaiv cov khoom siv, thiab kev sib tsoo ntawm cov khoom sivAluminium npog phaj rau roj teeb, thov koj tuaj yeem sab laj thiab sib tham txhua lub sijhawm. Peb yuav cia siab rau peb cov kws tshaj lij kev sib sau ua ke los muab cov kev daws teeb meem zoo rau koj, thiab tos ntsoov yuav ua haujlwm ua ke los txhawb kev kho dua tshiab ntawm lithium roj teeb tsim tshuab.
