Ukusetshenziswa kwe-Laser Precision Spot Welding embonini ye-Consumer Electronics
Eminyakeni yamuva nje, njengoba ukuncintisana emakethe yama-elekthronikhi abathengi kuye kwaba nzima kakhulu, abakhiqizi bemikhiqizo yama-elekthronikhi babeke phambili izidingo eziphakeme zemikhiqizo. Izindlela zokucubungula zendabuko zithambekele ekungazinzileni kwekhwalithi yomkhiqizo, ukuncibilika kwengxenye, ubunzima ekwakheni ama-nuggets ajwayelekile okushintshwa, kanye namazinga aphansi okukhiqiza. Ukuvela kobuchwepheshe bokucubungula nge-laser kungaxazulula ngokushesha lezi zinkinga kubakhiqizi bemikhiqizo yama-elekthronikhi. Ekukhiqizweni kwemikhiqizo yama-elekthronikhi ephezulu, ukucubungula nge-laser kudlala indima ebalulekile ekwenzeni ngcono ivolumu yomkhiqizo kanye nokuthuthukisa ikhwalithi, okwenza imikhiqizo ibe lula, ibe mncane, futhi izinze kakhudlwana. Kubikwa ukuthi ubuchwepheshe be-laser (izinqubo ezingaphezu kuka-20 ezahlukene) kanye nemishini yokukhiqiza ehlobene nayo isetshenziswa cishe kuma-70% ezixhumanisi zokucubungula nokukhiqiza umkhiqizo we-elekthronikhi.
Njengamanje, ukushisela indawo eqondile nge-laser kusetshenziswa kakhulu ezimbozweni zomkhiqizo we-elekthronikhi, izembozo zokuvikela, izixhumi ze-USB, ama-conductive patches, njll. Kunezinzuzo ezifana nokuguquguquka okuncane kokushisa, ukulawulwa okunembile kwendawo yesenzo kanye nendawo, ikhwalithi ephezulu yokushisela, ikhono lokufeza ukushisela kwezinto ezingafani, kanye nokwenza izinto ngokuzenzakalela okulula. Kodwa-ke, izindlela ezahlukene zokushisela zidinga ukwamukelwa lapho kushiselwa izinto ezahlukene.
Ngokusekelwe emiphumeleni yokuhlolwa okuningi, onjiniyela bokushisela bafingqe indlela engcono kakhuluukushisela indawo ngokunemba kwe-laserizindlela zezinto ezahlukene ezifana nezinto ezikhanyisa kakhulu, amashidi ensimbi amancane, kanye nezinto ezingafani ekukhiqizweni nasekukhiqizweni kwezinto zikagesi zabathengi.
1. Indlela Yokushisela Indawo Eqondile Ye-Laser Yezinto Ezibonisa Kakhulu
Lapho kushintshwa izinto ezikhanyayo kakhulu njenge-aluminium nethusi, ama-waveform ahlukene okushintshwa anomthelela omkhulu kwikhwalithi yokushintshwa. Ukusebenzisa i-laser waveform ene-pre-spike kungadlula isithiyo sokukhanya okuphezulu. Amandla aphezulu asheshayo angashintsha ngokushesha isimo sobuso bensimbi, aphakamise izinga lokushisa layo liye endaweni yokuncibilika, ngaleyo ndlela anciphise ukukhanya kobuso bensimbi futhi athuthukise ukusetshenziswa kwamandla. Ngaphezu kwalokho, ngenxa yokushisa okusheshayo kwezinto ezifana nethusi ne-aluminium, ukusetshenziswa kwe-waveform ebola kancane kungenza ngcono ukubonakala kwamabala okushintshwa.
Ngakolunye uhlangothi, izinga lokumuncwa kwe-laser kwezinto ezifana negolide, isiliva, ithusi, nensimbi liyancipha njengoba ubude be-wavelength bukhuphuka. Ku-copper, lapho ubude be-laser bungu-532nm, izinga lokumuncwa kwe-copper licishe libe ngu-40%. Ukuhlaziywa okuqhathanisayo kwezici ze-infrared lasers kanye ne-green lasers kukhombisa ukuthi ama-infrared lasers anosayizi omkhulu we-spot, ukujula okufushane kwe-focal, kanye nezinga eliphansi lokumuncwa yi-red copper; ama-green lasers anosayizi omncane we-spot, ukujula okude kwe-focal, kanye nezinga eliphezulu lokumuncwa yi-red copper. Lapho kwenziwa i-pulse spot welding ku-red copper kusetshenziswa ama-infrared lasers kanye ne-green lasers ngokulandelana, kutholakala ukuthi ubukhulu be-izindawo zokushisela ngemva kokushiselangama-laser e-infrared akuhambisani, kuyilapho amabala okushisela akhiwe ngama-laser aluhlaza efana kakhulu ngobukhulu, ahambisana ngokujula, futhi abushelelezi ebusweni (Izithombe 1-2). Ukushisela ngama-laser aluhlaza kufeza imiphumela eqinile, futhi amandla aphezulu adingekayo angaphansi kwengxenye kunalawo ama-laser e-infrared.
2. Indlela Yokushisela Indawo Eqondile Ye-Laser Yezinto Ezincane Zeshidi Lensimbi
Uma ama-laser endabuko angama-millisecond asetshenziswa ukushisela izinto ezincane zeshidi lensimbi, izinto zivame ukungena futhi izindawo zokushisela zikhulu kakhulu. Ngenxa yokungazinzi kwazo kanye nesilinganiso esiphansi sokumuncwa kwe-laser esimweni esiqinile, izinto ezikhanyayo kakhulu zivame ukubhekana nokuchitheka, ukushisela okunganele, kanye nezinye izinto ngesikhathi sokushisela. Ukuxazulula ubunzima bokushisela bamashidi amancane nezinsimbi ezikhanyayo kakhulu, ukuguqulwa kwe-analog kanye nedijithali kwenziwa ngokulandelana kwimodi ye-QCW/CW yama-fiber lasers. I-trigger eyodwa ingaveza imiphumela ye-N pulse, ifinyelele iphuzu elilodwa.ukushisela kwe-multi-pulsengamandla aphansi.
3. Indlela Yokushisela Amabala Okunemba Nge-Laser Yezinto Ezingafani
Lapho kushintshwa nge-laser izinto ezincane ezingafani, izinkinga ezifana nokushintshwa okunganele, imifantu, kanye namandla aphansi amalunga kungenzeka zivele. Lokhu kungenxa yokuthi lezi zinto ezimbili zinomehluko omkhulu ezimpahleni zomzimba, ukuncibilika okuphansi kokubambisana, futhi zithambekele ekwakheni ama-compounds aqhekekile phakathi kwe-metallic, okunciphisa kakhulu izakhiwo zemishini zejoyinti elishisiwe. Ukusebenzisa i-laser ye-nanosecond enekhwalithi ephezulu ye-beam ngokuskena okusheshayo kungalawula ngokunembile ukufakwa kokushisa ukuze kuvinjelwe ukwakheka kwama-compounds aphakathi kwe-metallic, kutholakale ukushintshwa kwe-lap kwamashidi ensimbi amancane angafani, futhi kuthuthukise ukwakheka kwe-weld kanye nezakhiwo zemishini.
Izinhlobo Ezivamile Zokushisela Okunembile
Yiziphi izinhlobo ezivamile zokushisela ngokunemba? Emkhakheni wokushisela, izinhlobo ezivamile zokushisela ngokunemba zifaka phakathi ukushisela ngokunemba, ukushisela nge-laser, ukushisela nge-ultrasonic, kanye nokushisela nge-micro arc spot. Ngenxa yezici ezihlukile zama-laser, uma kuqhathaniswa nezinye izinqubo zokushisela, ukushisela nge-laser ngokunemba kunezinzuzo zokusebenza kahle kakhulu, ubungane nemvelo, kanye nokunemba kokucubungula okuphezulu.
Izicelo Eziyinhloko Zokushisela Amabala Okuqondile Nge-Laser
Kusetshenziswa kuphi ukushisela amabala ngokunemba kwe-laser? Njengamanje, ukushisela amabala ngokunemba kwe-laser kungasetshenziswa ekushiseleni ngokunemba kwezingxenye ezincane nezizwela ukushisa ezifana nobucwebe, iziphethu zezinwele zamawashi, kanye nama-lead esekethe ahlanganisiwe. Kufanelekile ezimbonini ezifana namadivayisi e-optoelectronic, i-elekthronikhi, ukuxhumana, imishini, izimoto, imboni yezempi, kanye nobucwebe begolide. Njengohlobo lokushisela nge-laser, ukushisela amabala ngokunemba kwe-laser kuyindlela entsha yokushisela. Uma kuqhathaniswa nokushisela amabala ngokumelana kwendabuko, ukushisela amabala ngokunemba kwe-laser kunezinzuzo zayo eziyingqayizivele. Ngokusebenzisa i-laser njengomthombo wokushisa, ukushisela amabala kuyashesha, kunembile, kunokufakwa kokushisa okuphansi kanye nokuguqulwa okuncane kwezingxenye zomsebenzi. Ama-Laser anokufinyeleleka okuhle, okunganciphisa imikhawulo yesimo kanye nesakhiwo ngesikhathi sokushisela amabala. Awadingi inani elikhulu lemishini esiza, angashesha ukuzivumelanisa nezinguquko zomkhiqizo, futhi ahlangabezane nezidingo zemakethe. Ngokuthuthuka okusheshayo komnotho waseShayina kanye nokuthuthuka okuqhubekayo kwezinga lesayensi nezobuchwepheshe, ukuthuthukiswa kweubuchwepheshe bokushisela indawo ngokunemba kwe-laserifinyelele intuthuko esheshayo. Ngenxa yezinzuzo zayo zokunemba okuphezulu kokushisela kanye nesivinini esisheshayo, isetshenziswe kabanzi ekucutshungulweni kwezinto ezincane zensimbi.
Izinzuzo Zokushisela Ngokunemba Kwe-Laser
Okokuqala, ake siqonde izinzuzo zokushisela ngokunemba kwe-laser:
- Ingenza ukushisela kwezindlela ezahlukahlukene. Ama-laser anesiqondiso esiqinile, okuthola imiphumela emihle yokushisela izinto ezingajwayelekile.
- Ukushisela okuqinile. Ngemva kokugxila, indawo ye-laser incane kakhulu futhi inamandla amaningi, okuqinisekisa ukuthi ugongolo lwakha indawo yomthombo wokushisa ngesikhathi esifushane kakhulu. Ngemva kokuncibilika, ukupholisa, kanye nokwakheka kwekristalu, kwakheka umthungo kanye nendawo eqinile yokushisela.
- Ukunemba okuphezulu kokushisela. Ukusatshalaliswa kwamandla e-laser kunezici zesikhathi nezendawo, okuvumela ukuthi umsebe uhlukaniswe ngezindlela eziningi zokukhanya zokusebenza ngasikhathi sinye, okunikeza isiqinisekiso esinamandla sokunemba kokushisela.
- Isivinini sokushisela esisheshayo. Ubuchwepheshe be-laser buhlanganiswe nobuchwepheshe be-CNC yekhompyutha. Ngokuphathelene nokutholwa kwemishini ebalulekile kanye nezinhlelo zokulawula ukunyakaza, ukuhlanganiswa kwesistimu kuhlanganisa ukutholwa kwesikhathi sangempela kanye nokucubungula impendulo, okusheshisa isivinini sokucubungula ulwazi lwesistimu futhi kuthuthukise ukusebenza kahle kokushisela.
