Yuav ua li cas xaiv ultrasonic horn
Ultrasonic horn yog ib qho tseem ceeb ntawm kev kaw lus ultrasonic. Nws lub ntsiab kev ua haujlwm nyob rau hauv kev sib koom tes yog los ua kom nrov loj rau cov kev xaav lossis kev tshaj tawm ntawm cov neeg kho tshuab kev sib raug zoo, thiab mloog zoo rau lub zog ntawm ultrasonic, uas yog, lub zog khaws. Kuj hu ua ultrasonic ua haujlwm levers lossis ultrasonic concentrators.
Ultrasonic horns (ultrasonic horns), raws li lub npe qhia, yog cov khoom haumxeeb uas phim lub amplitude ntawm ultrasonic deeg nrog ultrasonic transducers. Nws lub ntsiab muaj nuj nqi yog hloov cov amplitude ntawm lub transducer (feem ntau nce), txhim kho qhov kev sib koom tes, txhim kho qhov kev ua tau zoo, ua kom zoo dua txhua yam zoo, txhim khu lub cua sov ua haujlwm, nthuav dav qhov kub, thiab muab lub neej kev pab cuam ntawm lub transducer. Ultrasonic transducer adjusts tus load txuam ntawm cov transducer thiab cov cuab yeej ultrasonic los txhim kho lub horn (ultrasonic horn), uas txo cov resonance impedance thiab ua rau nws ua hauj lwm nyob rau ntawm qhov muaj zog npaum li cas los txhim kho cov kev hloov ntawm electro-acoustic. Txo cov kub ntawm lub ultrasonic transducer thiab ua rau kom muaj kev pab cuam lub neej .
Nyob rau hauv txojcai ntawm ultrasonic welding tshuab, ultrasonic amplitude modulator ntaus amplifies tso zis ntau zog ntawm lub zog cog lus los ntawm lub transducer, thiab xaiv ntawm amplitude modulator yog mas analyzed los ntawm cov nram qab no cov ntsiab lus:
Ua ntej, qhov vuam chaw ntawm txoj haujlwm.
Qhov loj ntawm qhov vuam chaw muaj ntau txoj cai rau kev vuam voog, uas sib sau mus rau qhov kev xaiv ntawm amplitude modulator. Qhov loj dua lub vuam chaw, qhov ntau dua qhov kev thov rau kev siv welding. Lub amplitude modulation ntawm ultrasonic modulator yog tus siab, welding thaj tsam yog me, thiab lub vuam lub zog yuav tsum me, thiab xaiv ultrasonic modulating ntaus ntawv yuav ua tau correspondingly txo.
Qhov ob, cov khoom siv ua haujlwm.
Pp, Pe, nylon thiab lwm cov crystalline resins yog yooj yim rau weld, thiab lub amplitude ntawm tus ultrasonic modulator yog siab tshaj qhov ntawm cov ntaub ntawv amorphous.
Qeb peb, cov qauv workpiece.
Thaum tus qauv ntawm lub workpiece muaj lub qauv tsis muaj zog, xws li ib lub qhov taub los sis tsis muaj zog, vim nws yooj yim puas lawm, ib sab qis yuav tsum raug xaiv rau ultrasonic modulating ntaus kom tiv thaiv tsis tau tus ultrasonic ntaus tawm ua qhov kev puas tsuaj rau lub workpiece ua haujlwm thaum welding lub lag luam.
