Raws li cov khoom siv hluav taws xob tseem ceeb hauv lub zog hluav taws xob, tooj liab busbars tau siv dav hauv cov khoom siv hluav taws xob sib kis thiab hloov pauv, cov khoom siv hluav taws xob siab thiab qis, thiab lub cev muaj zog windings. Nws cov kev xav tau kev ua tau zoo suav nrog tsis yog tsuas yog cov conductivity zoo heev thiab lub zog txhua yam, tab sis kuj tseem muaj cov qauv nruj rau kev ua tiav thiab qhov zoo ntawm qhov chaw. Cov txheej txheem ua haujlwm ib txwm muaj xws li xuas nrig ntaus thiab kos duab muaj teeb meem xws li burr residue, kev ntxhov siab thiab kev ua haujlwm ntev, uas nyuaj rau ua tau raws li qhov yuav tsum tau ua ntawm siab -kawg cov khoom siv rau cov khoom siv hluav taws xob. Laser txiav tshuab, nrog rau nws tsis yog -cov yam ntxwv ntawm kev sib cuag, muab cov kev daws teeb meem tshiab rau siab - kev ua tiav ntawm cov tooj liab busbars.

 

 

 

 

 

(I) Technical txoj cai
Laser txiav tsom rau lub siab - lub zog ceev laser beam (lub zog ceev tuaj yeem ncav cuag ntau dua 10⁶ W / cm²) kom sov cov khoom siv ntawm tooj liab BusBar tam sim ntawd mus rau qhov kub thiab txias (kwv yees 2567 degree) los tsim cov vaporization qhov me me. Nyob rau tib lub sijhawm, siab -siab auxiliary gas (xws li nitrogen los yog oxygen) coaxial nrog lub beam tshuab tshem tawm cov hlau molten residue, thiab nruam txiav yog tiav raws li lub taub hau laser txav raws li preset trajectory. Cov txheej txheem no ua ke ua ke cov hluav taws xob ua hluav taws xob, vaporization theem hloov, thiab airflow dynamics kom ua tiav millimeter-theem rau micron-theem precision processing.

(II) Txheej txheem yam ntxwv
Kev ntxhov siab- ua haujlwm pub dawb: Tsis yog- kev sib cuag tshuab txiav zam qhov seem ntawm cov khoom siv dag zog ntawm cov txheej txheem xuas nrig ntaus thiab shearing, ua kom muaj kev ruaj ntseg ntawm lub koom haum sab hauv ntawm Lub Tsheb Npav Hluav Taws Xob, thiab tshwj xeeb tshaj yog tsim nyog rau kev sib txuas ntawm cov khoom siv hluav taws xob precision.

Ultra-precision ntug zoo: Qhov kev txiav ntug roughness tuaj yeem ncav cuag Ra Tsawg dua lossis sib npaug li 12.5μm, tsis muaj burrs, tev thiab lwm yam tsis xws luag, txo cov txheej txheem sib tsoo tom ntej, thiab ncaj qha ua tau raws li cov txheej txheem ntim rwb thaiv tsev.

Complex shape adaptability: Supports arbitrary two-dimensional and three-dimensional trajectory cutting, and can process ultra-thin row materials and special-shaped structures with a width-to-thickness ratio of >10, rhuav tshem cov duab txwv ntawm kev ua pwm ib txwm ua.

 

 

 

 

(I) Kev ntsuas rau siab -kev ua cov khoom siv hluav taws xob
Tooj liab muaj cov yam ntxwv ntawm kev xav tau siab (kev nqus ntawm 1μm wavelength laser<5%) and high thermal conductivity (401 W/(m・K)), which easily leads to laser energy attenuation and thermal deformation. Stable cutting is achieved through the following technical improvements:

Anti-siab-reflective optical txoj kev tsim: txais yuav ib tug tag nrho enclosed optical path system thiab multi-layer dielectric zaj duab xis lo ntsiab muag kom txo tau qhov kev puas tsuaj ntawm reflected lub teeb rau optical Cheebtsam thiab xyuas kom meej stability ntawm lub zog tso zis.

Energy modulation technology: combining pulsed laser and waveform optimization algorithm, through peak power increase (>10 kW) thiab mem tes dav tswj (10-100μs), nrawm nrawm los ntawm cov khoom siv rov qab pib thiab ua tiav cov vaporization zoo.

(II) Kev tswj xyuas cov txheej txheem tsis ua haujlwm
Txiav ceev sib piv: dynamically kho qhov ceev (0.5-5m / min) raws li lub thickness ntawm lub phaj (0.5-30mm) kom tsis txhob slag residue tshwm sim los ntawm ceev ceev los yog thermal deformation los ntawm qeeb qeeb qeeb.

Gas siab optimization: 0.5- 2MPa siab- lub siab pab roj yog siv los xyuas kom meej lub sij hawm tawm ntawm slag thiab inhibit oxidation cov tshuaj tiv thaiv (lub thickness ntawm cov oxide txheej yog tsawg tshaj li 10μm thaum siv nitrogen tiv thaiv).

Piv nrog rau cov txheej txheem ib txwm muaj, laser txiav tshuab txo cov nqi pwm thiab txo lub voj voog pov thawj (los ntawm 72 teev mus rau 4 teev) los ntawm kev tsim pwm, thaum txo cov txheej txheem pabcuam xws li annealing thiab sib tsoo, thiab txo tus nqi tag nrho ntawm 30% -50%. Nyob rau hauv cov chaw tawm tshiab xws li 5G hauv paus chaw nres tsheb thiab lub zog tshiab tsheb, nws cov peev txheej ua tau zoo thiab hloov pauv tau ua rau muaj txiaj ntsig zoo txhim kho qhov sib xyaw tsim ntawm cov khoom siv hluav taws xob.

 

 

(I) Cov ntsiab lus tseem ceeb ntawm kev tswj cov txheej txheem
Environmental parameter saib xyuas: Khaws qhov chaw ua haujlwm kub (20 ± 2 degree) thiab cov av noo (tsawg dua lossis sib npaug li 60% RH) txhawm rau tiv thaiv tooj liab nto oxidation los ntawm kev cuam tshuam kev txiav zoo.

Kev txheeb xyuas online kev koom ua ke: Tiag - lub sij hawm saib xyuas ntawm kev txiav trajectory sib txawv (qhov tseeb ± 0.05mm) los ntawm CCD qhov muag pom, ua ke nrog AI algorithm kom them nyiaj rau kev ua yuam kev.

(II) Technology evolution direction
Ultrafast laser daim ntawv thov: Femtosecond (10⁻¹⁵ qib thib ob) laser tshuab tuaj yeem ua tiav "kev ua haujlwm txias", txo qhov kub ntawm thaj tsam (＜50μm), thiab txhim kho cov kev ntseeg tau ntawm ultra{2}}thin busbars (＜0.1mm).

Kev txawj ntse ntau lawm kab: Raws li cov cuab yeej digital ntxaib, tus kheej - kev ua kom zoo ntawm kev txiav tsis zoo thiab kev kwv yees kev saib xyuas cov khoom siv tau raug pom, thiab kev ua haujlwm tau zoo dua los ntawm ntau dua 20%.

 

 

 

 

Laser txiav tshuab tau dhau los ua qhov kev xaiv tseem ceeb rautooj liab busbarua vim nws precision, yooj, thiab efficiency. Nrog rau kev ua tiav tas mus li hauv siab - lub zog fiber ntau lasers thiab kev tswj cov kev txawj ntse, cov cuab yeej no yuav txuas ntxiv mus rau hauv lub zog tshiab, siab - cov cuab yeej siv kawg tsim thiab lwm yam kev lag luam, thiab txhawb kev ua cov khoom siv hluav taws xob rau siab precision thiab ntsuab. Cov neeg koom nrog hauv kev lag luam yuav tsum tau ua kom zoo dua cov txheej txheem tsis tu ncua thiab ntxiv dag zog rau cov cuab yeej kev sib koom ua ke kev tsim kho tshiab txhawm rau tiv nrog qhov puas tau - nce kev lag luam xav tau.
