Taw qhia rau lub hauv paus ntsiab lus ntawm ultrasonic hlau vuam tshuab
1. Basic Knowledge Ntawm Ultrasonic Hlau Vuam
Ultrasonic hlau welding siv high-frequency vibration nthwv dej kom xa mus rau ob qhov chaw hlau yuav tsum tau welded. Nyob rau hauv lub siab, ob lub hlau nto rub tawm ib leeg los ua ib qho fusion ntawm molecular txheej. Qhov zoo yog ceev ceev, txuag hluav taws xob, thiab fusion. Lub zog muaj zog, zoo hluav taws xob conductivity, tsis muaj txim, ze rau kev ua haujlwm txias; Qhov tsis zoo yog tias cov hlau welded yuav tsum tsis txhob tuab heev (feem ntau tsawg dua los yog sib npaug li 5 hli), cov pob qij txha yuav tsum tsis txhob loj dhau, thiab yuav tsum tau ua kom muaj zog.
2. Qhov zoo ntawm vuam:
1) Cov khoom tsis yog melting thiab tsis-nkig hlau ntawm cov khoom siv vuam.
2) zoo hluav taws xob conductivity tom qab vuam, tsawg heev los yog yuav luag zero kuj coefficient.
3) Cov kev cai qis rau vuam hlau nto, oxidation lossis electroplating tuaj yeem vuam.
4) Lub sijhawm vuam luv, tsis tas yuav muaj cov flux, roj lossis cov khoom siv.
5) tsis muaj txim taws hauv vuam, kev tiv thaiv ib puag ncig thiab kev nyab xeeb.
3. Cov khoom tsim nyog rau Ultrasonic Hlau Vuam:
1) Nickel-hlau hydride roj teeb Nickel-hlau hydride roj teeb nickel mesh thiab npib tsib xee ntawv inter-melting thiab npib tsib xee ntawv inter-melting. .
2) Lithium roj teeb, polymer roj teeb tooj liab ntawv ci thiab cov ntawv npib tsib xee yog sib koom ua ke, thiab txhuas ntawv ci thiab txhuas ntawv yog kev sib koom ua ke. .
3) Cov xov hlau yog kev sib koom ua ke, thiab cov khoom yog entangled rau hauv ib qho thiab ntau ntau ntawm kev sib nrig sib.
4), cov hlau thiab lub npe ntawm cov khoom siv hluav taws xob, kev sib cuag, cov khoom sib txuas thiab kev sib koom ua ke.
5), kev sib koom ua ke ntawm cov khoom siv hluav taws xob loj loj, cov khoom siv hluav taws xob sib pauv, thiab cov paj hlwb ntawm cov khoom siv hauv tsev nto moo thiab cov khoom siv tsheb.
6), electromagnetic hloov, tsis muaj fuse hloov thiab lwm yam loj tam sim no, kev sib nrig sib melting ntawm dissimilar hlau daim.
7) Kev sib khi thiab txiav cov yeeb nkab hlau tuaj yeem ua dej thiab airtight.
4. Amplitude Parameters
Lub amplitude yog ib qho tseem ceeb parameter rau cov khoom yuav tsum tau welded, uas yog sib npaug rau qhov kub ntawm ferrochrome. Yog tias qhov ntsuas kub qis dhau, nws yuav tsis raug welded. Yog tias qhov kub thiab txias dhau lawm, cov khoom siv raw yuav hlawv lossis ua rau cov qauv kev puas tsuaj thiab lub zog. Vim hais tias cov transducers xaiv los ntawm txhua lub tuam txhab sib txawv, qhov amplitude ntawm cov zis transducer txawv. Tom qab hloov kho qhov sib txawv ntawm lub horn thiab lub horn, qhov ua hauj lwm amplitude ntawm lub horn yuav raug kho kom tau raws li qhov yuav tsum tau ua. Cov zis amplitude ntawm lub zog ntaus ntawv yog 10-20μm, thiab kev ua haujlwm amplitude feem ntau yog li 30μm. Qhov kev hloov pauv ntawm lub horn thiab lub taub hau vuam yog cuam tshuam nrog cov duab ntawm lub horn thiab lub taub hau vuam, qhov piv ntawm pem hauv ntej mus rau sab nraub qaum thiab lwm yam, thiab cov duab yog exponential. Kev sib txawv amplitude, kev ua haujlwm amplitude, stepped amplitude, thiab lwm yam muaj kev cuam tshuam zoo rau qhov piv, thiab thaj tsam piv ua ntej thiab tom qab yog proportional rau tag nrho qhov sib piv. Lub tshuab vuam ntawm cov tuam txhab sib txawv yog xaiv. Txoj kev yooj yim yog ua kom muaj qhov sib faib ua haujlwm ntawm lub taub hau vuam, uas tuaj yeem ua kom muaj kev ruaj ntseg ntawm cov amplitude tsis.
5. Zaus Parameters
Txhua lub tuam txhab ultrasonic vuam tshuab muaj qhov chaw ntau zaus, xws li 20KHz, 40 KHz, thiab lwm yam. lub horn thiab lub horn. Nws tau txiav txim siab tias qhov zaus ntawm lub tshuab hluav taws xob tau hloov kho raws li cov neeg kho tshuab resonance zaus kom ua tau raws li qhov sib xws, kom lub tshuab hluav taws xob ua haujlwm hauv lub xeev resonant, thiab txhua qhov yog tsim los ua ib nrab-wavelength resonator. Ob lub tshuab hluav taws xob thiab lub tshuab hluav taws xob resonant zaus muaj qhov ua haujlwm resonant ntau yam. Piv txwv li, qhov kev teeb tsa dav dav yog ± 0.5 KHz. Hauv qhov no, lub tshuab vuam tuaj yeem ua haujlwm ib txwm. Thaum peb ua txhua lub taub hau vuam, lub resonant zaus hloov kho. Lub resonance zaus thiab tsim qhov yuam kev yog tsawg dua 0.1 KHZ. Piv txwv li, 20KHz vuam lub taub hau, qhov zaus ntawm peb lub taub hau vuam yuav raug tswj ntawm 19.90-20.10 KHz nrog qhov yuam kev ntawm 5 ‰.
6. Lub Node
Lub taub hau vuam thiab lub horn yog tsim los ua ib nrab-wavelength resonator nrog kev ua haujlwm zaus. Raws li kev ua haujlwm, qhov amplitude ntawm ob lub ntsej muag kawg yog qhov loj tshaj plaws thiab qhov kev ntxhov siab yog qhov tsawg tshaj plaws, thiab qhov amplitude ntawm cov node sib raug rau qhov chaw nruab nrab yog xoom thiab qhov kev ntxhov siab yog qhov loj tshaj. Txoj hauj lwm ntawm cov node feem ntau yog tsim los ua ib txoj hauj lwm ruaj khov, tab sis txoj hauj lwm ruaj khov ib txwm yog tsim los kom muaj lub thickness ntau dua 3 hli, lossis qhov zawj yog tsau, yog li txoj hauj lwm ruaj khov tsis tas yuav muaj xoom amplitude, uas ua rau. qee lub suab thiab ib feem ntawm lub zog poob. Lub suab feem ntau yog cais tawm ntawm lwm cov khoom los ntawm lub nplhaib roj hmab los yog thaiv nrog cov khoom siv suab nrov. Lub zog poob yog coj mus rau hauv tus account thaum tsim cov amplitude tsis.
7. Netting
Ultrasonic hlau welding feem ntau yog siv rau ntawm qhov chaw vuam, thiab qhov chaw ntawm lub hauv paus yog tsim los nrog lub netting. Lub hom phiaj ntawm kev tsim mesh yog los tiv thaiv kev zawv zawg ntawm cov hlau qhov chaw thiab hloov lub zog mus rau qhov vuam txoj hauj lwm kom ntau li ntau tau. Lub mesh tsim feem ntau muaj cov square, pob zeb diamond, thiab strip mesh. Kub-clad hlau thiab lwm yam hlau-clad vuam taub hau thiab hauv paus yuav tsum tau tsim tsis muaj kev ntxhib los mos. Qhov loj thiab qhov tob ntawm cov mesh yog txiav txim siab raws li cov khoom siv vuam tshwj xeeb.
8. Kev ua haujlwm raug
Vim hais tias lub taub hau vuam ultrasonic ua haujlwm nyob rau hauv qhov kev vibration siab, nws yuav tsum tswj kom muaj qhov sib luag tsim kom tsis txhob muaj kev ntxhov siab tsis txaus ntseeg thiab kev co sab nraud los ntawm qhov asymmetry ntawm lub suab yoj kis tau tus mob. Lub taub hau vuam peb siv rau vuam siv lub longitudinal kev taw qhia ntawm ultrasonic kev co. Kev sib kis, rau tag nrho cov resonant system), kev co tsis sib npaug tuaj yeem ua rau kub thiab tawg ntawm cov plaub hau vuam. Ultrasonic welding yog siv rau kev lag luam sib txawv thiab muaj cov txheej txheem sib txawv. Rau tshwj xeeb nyias workpieces xws li lithium ion roj teeb ncej daim thiab tab welding, kub ntawv nyiaj txheej, thiab lwm yam., kev ua precision yog siab heev, tag nrho peb cov cuab yeej ua txhua yam CNC khoom (xws li machining chaw, thiab lwm yam) yog siv los xyuas kom meej tias. qhov precision ntawm machining ua tau raws li qhov yuav tsum tau ua.
9. Kev Pabcuam Lub Neej
Lub neej kev pab cuam ntawm lub vuam taub hau yog txiav txim los ntawm ob yam: thawj, khoom, thib ob, txheej txheem.
Cov ntaub ntawv: Ultrasonic vuam yuav tsum muaj cov hlau zoo (zoo txhua yam tsis zoo thaum lub sij hawm sonic kis tau tus mob), yog li cov khoom siv feem ntau yog aluminium alloy thiab titanium alloy, tab sis ultrasonic hlau vuam yuav tsum vuam lub taub hau hnav tsis kam (siab dua hardness) ua rau xaiv cov ntaub ntawv ntau dua. nyuaj, vim hais tias hardness thiab toughness zoo li inherently opposite, uas yuav tsum tau peb xaiv cov ntaub ntawv siab heev. Cov khoom siv hlau zoo uas peb xaiv tuaj yeem daws qhov kev tsis sib haum xeeb zoo dua. Lub neej zoo ntawm lub taub hau vuam yog maximized.
Cov txheej txheem: suav nrog kev siv thev naus laus zis thiab kev siv thev naus laus zis tom ntej, kev siv thev naus laus zis tau piav qhia ntxaws ntxaws ua ntej, cov txheej txheem tom ntej suav nrog kev kho cua sov thiab kev hloov pauv, raws li cov ntaub ntawv xaiv los ntawm peb lub tuam txhab, peb muaj cov txheej txheem kev kho cua sov qub los xyuas kom meej; nyob rau hauv txhua qhov vuam Tom qab lub taub hau tiav lawm, cov kev ntsuas tsis raug ntsuas thiab hloov kho nyias kom ntseeg tau tias cov khoom tsim tawm.
