Yuav Ua Li Cas Ultrasonic Vuam Hloov Ua Si Rau Kev Kho Mob Ua Si?
Vim tias cov qauv ntawm ntau cov khoom yas dhau deb dhau los ua pwm rau hauv ib thooj, nws yuav tsim nyog los sib sau ua ke lawv cov khoom siv rau hauv cov khoom tiav siv ib ntawm peb txoj kev koom nrog: Mechanical fasteners, adhesives lossis yas welds.
Ultrasonic vuam yog qhov nrov ua ke kev lag luam uas siv los ua cua sov thiab siab los tsim cov khoom lag luam ntawm lub xeev cov khoom sib dhos. Cov khoom siv tau tuav hauv qhov cuab yeej, tom qab ntawd ua rau lub cev loj (10-70 kHz), qhov tsis tshua muaj suab nrov (1-250 µm) cov tshuab kev co uas ua rau muaj qhov ua kom muaj kev sib txhuam, melting lub mating qhov chaw thiab tsim kom muaj qhov sib cuam tshuam molecular nyiaj. Ultrasonic welds yog dav siv los koom nrog thermoformed yas sibtham vim tias lawv tshem tawm qhov xav tau kev siv tshuaj lom neeg, tshuaj txhuam, screws lossis ntxiv rau.
Cov txheej txheem vuam ultrasonic sib xyaw ua ke rau qhov siab-ntim feem ntawm kev tsim khoom thiab kev siv tshuab vim hais tias weld cov voj voog tau nrawm - feem ntau tsawg dua li ib thib ob - thiab tsis tas siv cov khoom noj tau. Cov yas tivthaiv kev tsim qauv yuav tsum tsuas yog kev hloov kho me me kom ntseeg tau rov ua dua, lub zog siab ultrasonically welded sib dhos. Feem ntau (thiab feem ntau "pwm-nyab xeeb") kev hloov kho ntxiv ib qho me me "tus thawj coj ua lub zog" rau lub mating parts interface. Tus thawj coj hluav taws xob melts thiab ntws mus koom nrog ob thaj chaw. Hauv cov xwm txheej zoo, polymer txuas los ntawm txhua sab ntawm mating qhov chaw tsiv thoob lub interface thiab ua indistinguishable los ntawm niam txiv cov khoom.
Ntau cov thermoplastics, ob qho tib si amorphous (xws li polystyrene) thiab semi-crystalline (xws li nylon), tuaj yeem ua rau ultrasonically welded. Qhov tseeb, ob feem hauv qhov weld yuav tsum yog cov khoom tib yam. Txawm li cas los xij, ntau yam kev sib txuas ntawm cov plam uas tsis sib xws tuaj yeem ua rau ultrasonically welded yog tias lawv cov kub yaj (iav Hloov Kev Kub, Tg), zoo heev.
Ultrasonic vuam tuaj yeem muab qhov zoo tseem ceeb rau kev sib dhos ntawm cov khoom siv kho mob uas yuav tsum tau txwv tsis pub ua los ntawm cov screws thiab cov kuab tshuaj. Cov nplaum thiab cov kuab tshuaj muaj ntau lub sijhawm ua haujlwm ntev dua, tuaj yeem qhia cov khoom paug thiab tsis yooj yim rau qhov sib cuam tshuam. Qhov tsawg tshaj tsis muaj kev phais mob xws li ntsuas lub suab, cannulas, npliag thiab trocars feem ntau siv ultrasonic koom nrog nrog txoj kev vam meej.
Rau cov ntawv thov nyob rau hauv uas kev co siv nyob rau hauv ultrasonic vuam yuav cuam tshuam tsis zoo rau cov khoom siv hluav taws xob los yog cov khoom tawg yooj yim xws li daim nyias nyias lossis cov ntxaij lim dej, lwm cov yas sib koom nrog cov thev naus laus zis tau yooj yim. Ib qho kev xaiv yog laser vuam, qhov kev ua haujlwm tsis muaj kev vibration uas ua rau huv thiab hermetically kaw tsis sib haum ntawm cov ntau cov polyimmer sib txawv. Cov txiaj ntsig zoo li no, ua ke nrog tshwj xeeb rau kev ua kom zoo nkauj, tau ua rau laser vuam thev naus laus zis ntawm kev xaiv rau koom nrog cov khoom siv yas siv hauv ntau cov ntawv kho mob, suav nrog txhua yam ntawm cov tshuaj hauv vitro kuaj mob khoom siv rau cov cuab yeej siv tau rau kev saib xyuas tej thaj chaw deb lossis microfluidic kev xa tshuaj.
Muaj ntau cov kev xaiv, cov lus nug thiab cov kev sib tw hauv qhov tsim, kev txhim kho thiab kev tsim khoom ntawm cov kev ntseeg siab, rov hais dua koom txheej txheem kev daws teeb meem. Ib cov ntaub ntawv koom nrog cov khoom siv muab kev txawj ntse uas tuaj yeem muaj tus yam ntxwv zoo ntawm txhua yam los ntawm cov pov thawj ntawm lub tswv yim mus rau qhov kev txhim kho, kev ua kom loj hlob, cov ntaub ntawv sau, kev ua raws cai thiab ntau dua. Koom tes nrog cov kws paub txog kev paub txog tshuab hauv cov theem thaum ntxov ua rau cov chaw tsim khoom lag luam txiav txim siab qhov kev koom tes zoo tshaj plaws thev naus laus zis rau lawv cov khoom. Rau cov cuab yeej siv kho mob kev lag luam uas tsim thiab tsim cov khoom siv ntawm ntau lub txuas ntxiv, nws tseem muaj txiaj ntsig los koom tes nrog cov cuab yeej siv technology nrog cov peev txheej thoob ntiaj teb uas tuaj yeem muab cov khoom siv hauv zos vuam tsim thiab ntau lawm kev txawj ntse thiab kev txhawb nqa qhov twg lub rooj sib txoos ntaus.
