Ultrasonic soldering iron: yakakwira - kunyatsoisa chisimbiso uye welding mhinduro yevacuum girazi kugadzirisa.

Iyo yakakosha yekushanda logic yea ultrasonic solder iron ndeye kushandura simba remagetsi kuita maviri esimba mafomu kuti abudirire solder: kune rumwe rutivi, iyo yakavakwa - in inodziya inodziya inopisa iyo solder tip kune solder inonyungudika tembiricha, ichipa basic thermal simba rekutengesa; kune rumwe rutivi, jenareta ye ultrasonic inoshandura simba remagetsi kuita yakakwirira - frequency mechanical vibration (kazhinji 20kHz - 55kHz), iyo inotumirwa kune soldering tip kuburikidza ne transducer, zvichiita kuti ibudise inodzorwa radial kana axial vibration. Kusiyana nesimbi dzechinyakare dzekutengesa dzinovimba chete nekupisa kunyungudutsa solder, iyo ultrasonic solder iron's soldering process yakakamurwa kuita matanho matatu akakosha, akanyatsokodzera kune zvakaomesesa zvinodiwa zvevacuum girazi solder.

Chekutanga, preheating uye nhanho yekunyunguduka: iyo solder tip inopisa kusvika kune preset tembiricha (kazhinji 50-100 ℃ yakakwirira kupfuura iyo solder melting point), ichibata solder kuti inyungudutse. Panguva imwe chete, pfuti yemhepo inopisa inopisa waya ye solder (kusvika kune tembiricha 150 - 200 ℃ yakakwirira kupfuura iyo solder inonyungudika), kuve nechokwadi chekunyunguduka nekukurumidza uye yunifomu ye solder uye kudzivirira kupisa kwenzvimbo kunogona kukuvadza girazi substrate. Kechipiri, mu cavitation yekuchenesa nhanho: yakakwirira - frequency vibration inotumirwa kune yakanyungudutswa solder, zvichikonzera inodzorwa acoustic cavitation athari. Simba rekuita rinogadzirwa kana cavitation microbubbles inoputika inoparadza zvachose iyo oxide firimu uye tsvina pamusoro pegirazi metallization layer. Pasina kuwedzera chero flux, kusangana kwakazara pakati peiyo solder uye yakachena metallization layer inowanikwa, kubvisa dambudziko remasara emvura anosvibisa iyo vacuum layer kubva kune sosi. Pakupedzisira, padanho rakakora rekubatanidza: simba rekuzunguza rinomanikidza solder yemvura kupinda mukati memagap uye mamicropores egirazi metallization layer, ichisvina mabubble emhepo mukati meiyo solder. Izvi zvinoita kuti pave negapless, smooth, uye aesthetically pleasing solder joint, panguva imwe chete ichikurudzira kuumbwa kweyunifomu intermetallic compound pakati pe solder uye metallization layer, inovandudza zvakanyanya simba uye airtightness yejoini ye weld uye kusangana kwenguva refu - yenguva yekuisa chisimbiso zvinodiwa zvevacuum glass.

Izvo zvinodikanwa zvevacuum girazi ndezve "high airtightness, hapana kusvibiswa kwetsvina, uye hapana substrate kukuvara." Iyo fluxless welding, yakaderera - tembiricha chaiyo tembiricha kutonga, uye dense, bubble- yemahara solder majoini e ultrasonic solder irons anozadzisa izvi zvinodiwa, zvichiita kuti anyanyokodzera kubatanidza girazi kune metallization layer, simbi mafuremu, makoramu ekutsigira, uye zvimwe zvikamu. Iyi yave tekinoroji yakakosha yekugadzirisa kukanganisa kwechinyakare welding.

Core Application Scenarios ye Ultrasonic Soldering Irons muVacuum Glass Processing

Mune vacuum girazi kugadzirisa kuyerera, iyo welding process inonyanya kutarisisa pamatanho matatu akakosha: pre - kupfekedza kwemetallization layer, kumucheto kuvharwa, uye tsigiro mbiru kugadzirisa. Ultrasonic solder irons, ine compact dhizaini uye yakanyatso kudzora tembiricha uye vibration paramita, inogona kuchinjika kuchinjika kune ese manyorero ekushanda uye otomatiki mitsara yekugadzira, ichitamba isingadzokerike chikamu muchikamu chimwe nechimwe.

(I) Pre-coating yeSolder yeGlass Metallization Layer

Iyo yepamusoro yevacuum girazi haigone kusungirirwa zvakavimbika zvakananga kune simbi solder. Metallization layer (yakadai seAg simbi paste, Cu - Ag alloy paste, zvichingodaro) inofanira kunge yakagara - yakavharidzirwa panzvimbo dzinofanira kuiswa weld (kazhinji mipendero ina). Solder pre-coating chinhu chinodiwa kuti uve nechokwadi chekutevera chisimbiso mhando. Traditional pre-coating process inotarisana nezvinetso senge kusaenzana solder ukobvu uye kusimba kusungirirana nemetallization layer, zvichitungamira kune isina kukwana kana kupotsa welds panguva yaitevera yekuisa chisimbiso.

Ultrasonic soldering irons inogona kunyatso kuendesa solder wire kuburikidza newaya yekudyisa mudziyo, uye, pamwe chete ne adsorption motion chikuva kugadzirisa girazi substrate, tyaira iyo solder iron tip kuti ifambe zvakaenzana kuburikidza netatu - dimensional motion component, uchiwana precye pre-coating of the solder. Munguva yekutangira - yekuputira, tembiricha inogona kudzorwa pakati pe150 ℃ ne400 ℃, uye solder layer ukobvu hunogona kunyatsodzorwa pakati pe0.1mm ne3mm, ichisangana nezvinodiwa pahupamhi uye ukobvu hwevacuum girazi kumucheto chisimbiso. High-frequency vibration inova nechokwadi chekuti solder uye metallization layer yakanyatsobatanidzwa, ichigadzira yunifomu pre-welded layer. Kuiswa chisimbiso kunotevera kunongoda kupisa kunyungudutsa pre-welded layer, nekukurumidza kuumba yakagadzikana yekuisa chisimbiso chimiro uye zvakanyanya kuderedza chiyero chezvikara. Muchiitiko ichi chekushandisa, tembiricha yakamisikidzwa uye oscillation kubuda kweiyo ultrasonic solder iron inogona kunyatsodzorwa kuburikidza nenharaunda yenzvimbo network, zvichiwedzera kuvandudza kuenderana uye kugadzikana kwe pre-kupfeka.

(II) Vacuum Girazi Kumucheto Kuvhara Welding

Kuisa chisimbiso cheEdge ndiyo inonyanya kukosha maitiro muvacuum girazi kugadzirisa. Hunhu hwayo hwekuisa chisimbiso hunotarisisa kugona kwevacuum layer kuchengetedza vacuum, nekudaro ichikanganisa kupisa kwechigadzirwa, kuita kwemazwi ekudzivirira, uye hupenyu hwesevhisi. Chisimbiso chemupendero chisimbiso chinowanzo shandisa yakaderera- kunyunguduka - point girazi poda yekuisa chisimbiso kana yakajairika brazing. Iyo yekutanga inowanzoita chisimbiso chisimbiso chekutsemuka, nepo chekupedzisira chichida flux, zvichitungamira kune vacuum layer kusvibiswa, uye majoini anotengeswa anowanzo kuvhuvhuta emhepo, achitadza kuzadzisa refu-nguva yakakwirira yekudzivirira mhepo zvinodiwa.

Ultrasonic solder irons inogona kuwana fluxless brazing seals pamicheto yevacuum glass, kunyanya yakakodzera kusvina ne low-temperature metal solder. Munguva yekuputira, iyo solder iron tip inofamba ichimhanya inogara ichitevedza girazi kumucheto, uye solder yakanyungudutswa, iri pasi pekudengenyeka, yakaenzana inovhara iyo metallized layer, ichigadzira inoenderera uye dense yakavharwa weld. Simba rekuzunguza rinosvina mabubbles emhepo mune solder, kudzivirira mapundu muchikamu chekuvhara. Panguva imwe chete, yakaderera - tembiricha welding inodzivirira girazi kubva pakutsemuka nekuda kwekunyanya kupisa kwekushushikana, kuchengetedza flatness uye kuvimbika kwegirazi pamusoro. Kune hombe- saizi vacuum girazi, ultrasonic solder irons inogona kubatanidzwa mune otomatiki welding mitsara yekugadzira. Yakasanganiswa neiyo chaiyo yekumisikidzwa kweiyo adsorption inofamba chikuva, inoshanda uye yunifomu kumucheto sealing welding inogona kuwanikwa, zvakanyanya kuvandudza kugona kwekugadzira uye kuenderana kwechigadzirwa, uye kugadzirisa dambudziko rekusaenderana kwemhando mune yechinyakare manual welding.

(III) Tsigira Column Kugadzirisa Welding

Makoramu akarongeka akarongeka anofanirwa kuisirwa muvacuum layer yevacuum girazi kudzivirira kunze kwemhepo uye kudzivirira girazi deformation. Kubatana pakati pembiru dzekutsigira uye girazi metallized layer kunofanirwa kuve nesimba rakakwana asi kwete kukuvadza vacuum chisimbiso. Tsigiro yechinyakare mbiru kugadzirisa kazhinji inoshandisa adhesive bonding kana yakajairika welding. Adhesive bonding inowanzoita kuchembera uye kuvharika, nepo welding yakajairwa inogona kukuvadza girazi kana kugadzira mabhuru, zvichikanganisa kugadzikana kwevacuum layer.

Ultrasonic solder irons, ine compact dhizaini uye yakanyatso kudzora simba, inogona kuwana yakanangwa welding yemakoramu ekutsigira: iyo tsigiro mbiru inoiswa munzvimbo yakasarudzika pane girazi metallization layer, uye solder tip inonyatso kuenderana nepasi pekoramu yekutsigira. Kuburikidza nekudziya kwenzvimbo uye yakakwirira-frequency vibration, iyo yakasimba weld joint inokurumidza kuumbwa pakati pekoramu yekutsigira uye metallization layer. Iyo welding nzvimbo yakatarisana, ine diki kupisa kupararira siyana, kudzivirira kukuvadzwa kwekoramu yekutsigira uye girazi substrate. Panguva imwe chete, iyo weld joint ine dense uye isina gap, kuve nechokwadi chekugadzirisa kwakasimba kwekoramu yekutsigira pasina kukanganisa mhepo uye kutendeseka kwevacuum layer. Iyi nzira yewelding inochinjika zvinochinjika kuti itsigire makoramu ehukuru hwakasiyana uye zvinhu, inopa kuchinjika kwakasimba, uye inonyanya kukodzera kugadzirisa makoramu ekutsigira kwegirazi diki rekuvhaira rinoshandiswa mune chaiyo zviridzwa uye yakakwirira-yekupedzisira midziyo yemumba.
