Hauv xyoo 1982 kev tso suab paj nruag" Victor Victoria" ;, Julie Andrews hu nkauj ua qhov kawg ntawm qhov kawg ntawm nws tus cwj pwm Paris cabaret qhia. Nws tuav cov ntawv sau cia, thiab tsom iav champagne hauv chav tsev tag nrho cov khoom tawg. Qhov no yog ib qho piv txwv zoo ntawm cov suab siab li cas lossis cov suab nrov siab cais cov khoom sib txawv. Tab sis koj puas paub tias koj tuaj yeem siv lub suab nrov ceev los ua cov ntawv sib txuas ua ke? Ultrasonic welding thev naus laus zis yog siv los ua ke cov khoom lag luam hauv ntau qhov chaw lag luam-los ntawm cov cuab yeej siv kho mob mus rau khau kis las rau tsheb.
Feem ntau, koj tuaj yeem siv cov khawm ceev xws li ntsia hlau, ntsia hlau, lossis xov kom khi cov khoom. Qhov no siv rau cov hlau, ntoo, ntaub thiab yas. Rau ntau plastics, kua nplaum yog siv. Cov kua nplaum tsim ib qho kev sib txuas ntawm cov kua nplaum nws tus kheej thiab saum npoo ntawm cov khoom siv yas uas sib khi. Cov hlau tuaj yeem sib koom ua ke los ntawm cua sov lwm cov hlau ua cov nplaum, xws li cov hlau lead hauv cov hluav taws xob sib txuas. Hloov pauv, cov hlau tuaj yeem ncaj qha melted (welded) ua ke; thaum lub molten hlau nto txias, cov hlau yuav sib txuas ua ke. Vuam feem ntau yuav tsum tau qhib cov nplaim hluav taws lossis nplaim hluav taws kom ncav cuag qhov kub siab uas yuav tsum tau txua cov hlau ua ke. Yog li ntawd, rau qee cov haujlwm tsim ua, qhov no tuaj yeem yog tus txheej txheem kim.
Cov txheej txheem theem pib ntawm ultrasonic vuam tuaj yeem piav qhia los ntawm cov theem hauv qab no:
1. Qhov ntawm yuav tsum tau welded raug muab tso rau hauv qhov thaiv lossis lub qhov khoom siv.
2. Lub tshuab raj yog nyob rau hauv kev sib cuag nrog rau feem kom tau txais welded.
3. Thov nias siab txhawm rau ua kom lub taub hau vuam nyob rau hauv kev sib cuag nrog cov khoom siv vuam thiab tuav nws ua ke.
4. Lub tshuab raj ua rau cuam tshuam ultrasonic kev co kom sov cov khoom. Qhov kev co txav mus los los yog nqis los yog sab laug thiab txoj cai los ntawm tsawg dua ib millimeter.
5. Cov khoom siv no ua ke ua ke.
6. Lub tshuab raj yuav thim rov qab thiab cov khoom siv vuam tuaj yeem tshem tawm ntawm lub thaiv.
Lub sijhawm vuam, thov tso siab thiab ntsuas kub tau tswj hwm los ntawm lub computer lossis microprocessor hauv cov khoom siv vuam. Dab tsi tshwm sim thaum lub sijhawm vuam nyob ntawm qhov xwm txheej ntawm cov khoom siv. Hauv cov hlau, ultrasonic kev co yog kis mus tib seem rau lub dav hlau ntawm cov khoom. Kev txhuam kev kub ua rau qhov kub ntawm cov hlau kom kub txog li ib feem peb ntawm cov nplaim hluav taws kub, tab sis nws tsis yaj cov hlau. Hloov, tshav kub tshem tawm cov hlau oxide thiab cov yeeb yaj kiab nyias los ntawm lub sab. Qhov no tso cai rau cov hlau atoms txav ntawm ob qhov chaw thiab tsim cov ntawv cog lus uas tuav cov hlau ua ke.
Cov yas, qhov kev co yog sib tshooj rau lub dav hlau ntawm cov khoom, thiab kev sib txhuam tuaj yeem tsim qhov kub kom txaus kom yaj cov yas. Cov roj ntsha yas ua ke sib xyaw ua ke thiab tsim ua ke. Tom qab txias, cov txheej txheem yas ntsa ua ke ua ke. Lub sijhawm vuam tuaj yeem sib txawv, tab sis lub vuam tuaj yeem tsim tsawg tsawg li 0.25 vib nas this.
Cov yam ntxwv ntawm ultrasonic vuam suav nrog qhov zaus ntawm lub suab yoj (feem ntau 20, 30, lossis 40 kHz), lub siab tuav cov khoom ua ke, thiab lub sijhawm siv ultrasonic yoj (ib feem ntawm ob lossis ntau dua ntawm ib pliag).
Piv nrog rau cov txheej txheem ib txwm, ultrasonic vuam muaj ntau yam zoo. Ua ntej, piv rau lwm txoj kev, vuam tau ua ntawm qhov kub tsawg. Yog li, cov tuam ntxhab tsis tas yuav siv roj lossis lwm lub zog siv kom ncav cuag kub. Qhov no ua rau cov txheej txheem pheej yig dua. Nws kuj tseem nrawm dua thiab nyab xeeb dua.
Ultrasonic welding tsis tas yuav cov roj thiab qhib cov nplaim taws, yog li nws yog cov txheej txheem kev nyab xeeb dua piv rau lwm txoj kev vuam. Cov neeg ua haujlwm yuav tsum tsis txhob chwv cov roj lossis cov kuab tshuaj lom. Hauv cov khoom siv hluav taws xob, cov xov tooj liab liab ib txwm txuas nrog rau kev sib txuas lus hluav taws xob ntawm lub rooj tsav xwm hauv Circuit Court dhau los ntawm solder. Kev siv ultrasonic vuam tuaj yeem ua tiav tib txoj haujlwm nyob rau hauv ib lub sijhawm luv luv yam tsis muaj kev ua haujlwm rau cov neeg ua haujlwm rau cov pa ntawm cov hlau lead tsis zoo. Txawm hais tias raug cov suab nrov nrov ntau zaus tuaj yeem ua rau lub rooj sib hais ntawm cov neeg ua haujlwm, qhov kev phom sij no tuaj yeem txo tau yooj yim los ntawm kev tso lub tshuab vuam ultrasonic rau hauv lub thawv kev nyab xeeb lossis tawb thiab / lossis siv pob ntseg.
Thaum kawg, ultrasonic vuam yog qhov muaj zog thiab ruaj khov zoo li vuam sib txuas ntawm cov khoom qub-qhov no tsuas yog ib qho laj thawj vim li cas cov qauv no siv hauv kev tsim tsheb. Txhawm rau ua kom cov tsheb sib zog thiab muaj roj ntau dua, cov neeg tsim tsheb siv hluav taws xob siv txhuas lub cev hlau. Piv nrog rau kev siv vuam ib txwm, ultrasonic vuam tuaj yeem siv los txhawm rau txhawm rau lub sijhawm luv thiab thaum qis dua.
