Ntsiab cai rau ultrasonic yas vuam
Ultrasonic welding yog ib hom kev ua ke ua ke ob qho chaw ntawm cov khoom siv tib los sis sib xws siv ultrasonic vibrations uas tsim cov khoom hauv lub xeev sib txuas ntawm lawv . Qhov zoo ntawm kev siv cov txheej txheem no yog nyob hauv vib nas this lub zog siab, roj thiab dej nruj daim thaiv yog ua tsis muaj qhov ntsuas, kua nplaum, xov, kab laug sab lossis lwm yam khoom sib txuas. Cov khoom uas tau muaj qhov txuas tsis tas yuav tsis tas yuav nyob rau hauv ib qho kev rau jig, kom lawv siv tam sim ntawd muaj peev xwm nyob hauv txoj kab automation. Lub ultrasonic welding ntawm plastics yog tus txheej txheem eco hauv kev uas siv zog tsawg zog thaum ua tus nqi zoo, ruaj khov, thiab huv weld. Cov txheej txheem yog siv hauv hluav taws xob, tshuab computer, automotive, aerospace, kev kho mob, thiab ntim cov lag luam, rau npe ob peb .
Ib lub cav ultrasonic welding yog ua los ntawm ib lub rooj sib txoos sib txeeb hu ua pawg . Qhov no yog ua los ntawm peb yam khoom: sonotrode, a booster thiab ib lub veld worn. Lub sonotrode yog lub hauv paus ntawm kev co. Sab hauv nws yog piezoelectric ceramic disks sandwiched ib ncig ntawm hlau daim hlau uas clamped tightly mus rau ib lub titanium kheej kheej. Kev siv hluav taws xob ntau ces muab rau nws los ntawm ib txoj kab los ntawm lub zog qhov hluav taws xob. Raws li qhov no tsis tsim kom muaj kev kub ntxhov kom tau txias dua rau cov thermoplastic feem ntau, ib lub koob tshuaj siv los ua kom nrov loj rau cov lus vibrations rau tus qauv uas yuav tsum tau siv rau cov txheej txheem welding. Lub weld horn hloov lub zog nyob rau hauv lub vibrations mus rau thermoplastic ua hauj lwm pieces. Lub weld horn yog tsim los kom haum cov kev sib txuas ntawm cov hauj lwm ua. Nws attenuates lub co mus rau ib tus nqi thiab siv cov rog yuav tsum ua rau txoj kev ua haujlwm
Txoj kev siv welding no nyob ntawm cov khoom uas siv softening tab sis tsis yog yaj , yog li nws yog qhov zoo tshaj plaws rau cov thermoplastics thiab tsis thermoset polymers. Feem ntau cov thermoplastics muaj ib lub qauv amorphous nrog qee qhov kev kawm ntawm crystallinity, lub ntsiab lus muaj qee qhov chaw uas muaj kev txiav txim siab. Thermoplastics muag muag ntau ntau ntawm qhov kub thiab muaj lub iav hloov kub. Cov thermoset polymers yog crystalline thiab muaj ib qho kev sib tshuam ntawm qhov chaw. Ib tus crystalline polymer yuav nyob twj ywm kom txog thaum nws nce mus txog nws qhov chaw melting thiab ces yaj tas ib zaug. Amorphous thermoplastics kuj muaj qee cov kev nqus, qis tensile zog thiab tensile modulus, dua ductility thiab feem zog thiab qis creep tiv tsis zoo rau feem ntau crystalline polymers. Piv txwv, ABS, acrylic, polycarbonate thiab PVC yog cov qauv polymers uas muaj tsawg los sis tsis muaj cov kab crystalline. Cov plastics zoo suited rau ultrasonic vuam. Ultrasonic welding ntawm ob qhov chaw ua los ntawm cov khoom siv tib yam khoom siv yuav tau txais qhov zoo tshaj plaws tshwm sim. Txawm li cas los xij, qee zaum ob thermoplastics sib txawv tau welded siv ultrasonics, piv txwv li thaum cov ntaub ntawv sib kis tau zoo tshaj thiab muaj cov ntsiab lus txhim kho melting. Ib qho ntawm ob qho zoo tshaj ntawm cov khoom ntawm plastics rau hom vuam yog ABS thiab acrylic.
Polymers xws li PE, PP, PE thiab PIA yog crystalline thiab yuav nqus deeg ua ntej lub zog ntawm lub chaw ultrasonic tuaj yeem mus dhau rau ntawm qhov chaw weld. Nws yog vim li no nyuaj rau koom nrog cov kev siv no hom vuam. Ib qho uas feem ntau tau thov kev sib txuas yog polyethylene thiab polypropylene, tab sis cov no yog ob qho tib si crystalline thiab tsis sib xws
Sonic welding yog siv los ua Butane ntais, cov khoom ua si, kav dej thiab cov hlua kom tso dej. Sab qaum feem ntawm cov kis las khau nquag tau siv ultrasonic vuam es tsis yog stitching lossis gluing. Cov txheej txheem tsim khoom siv rau cov khoom siv hauv vaj hauv tsev yuav tsum muaj ntau yam khoom yas los sib koom ua ke. Piv txwv ntawm cov txheej txheem no muaj xws li lub vijtsam npo ntawm cov qauv ntawm lub tshuab ntxuav tais diav thiab ob lub nkoj ntawm lub twj tso kua mis. Hauv kev lag luam automotive, muaj pua pua kev siv rau sonic vuam xws li vuam ua ke ntawm ntu teeb, cov khoom siv, thiab thaij. Muaj lus ceeb toom tias Apple nrhiav kev siv cov txheej txheem no ua rau lawv cov pob ntseg, siv cov txheej txheem ntse rau qee yam ntawm lawv cov khoom. Qhov no yuav ua rau lub pob ntseg hnov ib yam dab tsi zoo dua .
