YUAV UA LI CAS ULTRASONIC PROCESS WORKS
Hauv kev siv ultrasound, cov vibrations muaj qhov siab siv qhov chaw ntawm ob feem ntawm lub vibrating cuab tam, feem ntau hu ua "horn" los yog "sonotrode." Vuam tshwm sim los ntawm kev kub ntxhov ntawm lub nruab nrab ntawm qhov nruab nrab. Ultrasonic deeg yog tsim los ntawm cov khoom ntawm lub zog - lub hwj huam mov, hloov khoom nruab nrab, tshuaj, thiab tshuab raj-uas xa cov neeg ua hauj lwm kev co mus rau qhov chaw.
Lub hwj huam yuav siv qhov hluav taws xob txheem hluav taws xob thiab hloov nws mus rau kev khiav haujlwm. Hauv qhov piv txwv nram qab no, peb yuav siv ntau hom ultrasonic vuam ntau ntawm 20 kHz, tab sis yog qhov vuam siv tau ntau tshaj li ntawm 15 mus rau 60 kHz kom tau raws li kev xav tau tshwj xeeb. Hauv kev khiav hauj lwm, lub hwj huam muab xa hluav taws xob tso rau ntawm qhov teev zaus ntawm RF cable mus rau qhov sib hloov. Lub converter siv piezoelectric ceramics los hloov cov hluav taws xob lub zog rau cov neeg kho tshuab ntawm kev ua haujlwm ntawm kev khiav hauj lwm zaus ntawm lub hwj chim. Qhov no mechanical kev co yog nce lossis tsawg dua raws li lub qauv ntawm lub koob thiab lub plab. Qhov kev kho kom zoo ntawm kev kho siab yog qhov txiav txim siab los ntawm ib tug neeg siv khoom siv thiab yog raws li cov khoom siv thermoplastic siv nyob rau hauv qhov chaw.
Cov khoom yuav tsum tau muab pov tseg yog muab tso rau hauv ib qho chaw kho tsheb, feem ntau nrog cov pneumatic actuator uas tuav lub koob thiab lub plab. Hauv qab no load, cov neeg kho tshuab kev sib kis raug xa mus rau lub nruab nrab ntawm cov khoom siv, uas tsom lub zog los tsim kev sib tshuam thiab kev sib tsoo tawm. Qhov kev sib txhuam no ua rau kub thiab tom qab yaj, uas ua rau lub voj voos txuas.
Qhov yooj yim Cheebtsam ntawm lub kaw lus ultrasonic yog lub hwj huam mov, tus actuator, thiab ib pawg. Lub hwj huam yuav siv txoj hlua hluav taws xob ntawm ib qho nominal 120-240V thiab nws hloov mus rau hauv kev teeb tsa muaj hluav taws xob, qhov teeb meem siab tshaj. Nws kuj muaj qhov programming tsim nyog los khiav lub actuator thiab pawg hauv kev tswj kom ua tau raws li qhov xav tau ntawm qhov kev xav tau. Cov actuator, pneumatic los yog hluav taws xob servo-operated, thiab muaj raws li ib tug stand-alone benchtop unit los yog nrog rau hauv lub kaw lus automated, txav ultrasonic tooling mus rau qhov chaw koom nrog. Nws siv qhov yuam kom tsim nyog rau cov ntaub ntawv los pab tsim cov vuam mob.
Ultrasonic pawg ua tiav qhov system. Nws hloov cov vibratory zog, los ntawm kev hu ncaj nraim nrog rau qhov chaw, rau qhov sealing / sib txuas zais. Qhov pawg feem ntau muaj peb yam khoom: lub transducer lossis converter (piav qhia saum toj no), uas muaj cov piezoelectric ceramic crystals uas oscillate ntawm qhov zaus ntawm cov lus siv fais fab-cov teeb liab. Raws li cov crystals oscillate, lawv lub cev nthuav dav thiab daim ntawv cog lus, tsim cov kev tawm suab ntawm txhua qhov chaw (piv rau lub ncov siab tshaj plaws ntawm ncov siab) nyob rau sab nraud ntawm lub transducer.
Tshooj thib ob, lub koob, nrog lub nplhaib ntawm nws hauv nruab nrab, nws ua ob yam haujlwm: Nws ua raws li qhov teeb meem taw qhia rau pawg, thiab tseem ua haujlwm kom nrov lossis txo qhov kev tawm suab uas tsim tawm hauv lub transducer.
Qhov thib peb thiab zaum kawg ntawm lub tshooj yog lub kub (sonotrode) uas yuav tiv tauj rau qhov chaw sib koom ua ke. Lub horn yuav tsim kom haum qhov profile ntawm tsis yeem los koom los yog muaj peev xwm sealing qhov profile ntxiv rau nws lub ntsej muag sib txuas hauv zaj duab xis / textile. Rau txhua daim ntawv thov, lub horn yog tsim los ua ke nrog rau lwm pawg khoom kom ncav cuag theem zoo ntawm kev tso zis rau kev tso cai rau ultrasonic vuam kom tshwm sim zoo li ua tau.
