Kugwiritsa Ntchito Laser Precision Spot Welding mu Consumer Electronics Industry
M'zaka zaposachedwa, pamene mpikisano pamsika wa zamagetsi wa ogula ukukulirakulira, opanga zinthu zamagetsi apereka zofunikira kwambiri pazinthu. Njira zokonzera zinthu zakale zimakhala ndi vuto losakhazikika pa khalidwe la zinthu, kusungunuka pang'ono, kuvutika kupanga zinthu zosungunuka bwino, komanso kuchuluka kochepa kwa zokolola. Kutulukira kwa ukadaulo wokonza zinthu pogwiritsa ntchito laser kumatha kuthetsa mavutowa mwachangu kwa opanga zinthu zamagetsi. Pakupanga zinthu zamagetsi zapamwamba, kukonza zinthu pogwiritsa ntchito laser kumachita gawo lofunika kwambiri pakukweza kuchuluka kwa zinthu ndikuwongolera khalidwe, kupangitsa zinthu kukhala zopepuka, zopyapyala, komanso zokhazikika. Akuti ukadaulo wa laser (njira zoposa 20 zosiyanasiyana) ndi zida zofananira zopangira zimagwiritsidwa ntchito pafupifupi 70% ya maulalo opangira zinthu zamagetsi ndi zopangira.
Pakadali pano, kuwotcherera malo olondola pogwiritsa ntchito laser kumagwiritsidwa ntchito makamaka pa ma casing amagetsi, zophimba zotchingira, zolumikizira za USB, ma conductive patches, ndi zina zotero. Ili ndi zabwino monga kusintha pang'ono kwa kutentha, kuwongolera bwino malo ogwirira ntchito ndi malo ake, kuwotcherera kwapamwamba, kuthekera kopeza kuwotcherera zinthu zosiyana, komanso njira yosavuta yodzichitira yokha. Komabe, njira zosiyanasiyana zowotcherera ziyenera kutsatiridwa powotcherera zinthu zosiyanasiyana.
Kutengera zotsatira za mayeso ambiri, mainjiniya olumikiza zitsulo afotokoza mwachidule njira yabwino kwambirikuwotcherera malo molondola pogwiritsa ntchito lasernjira zopangira zinthu zosiyanasiyana monga zinthu zowala kwambiri, mapepala achitsulo owonda, ndi zinthu zosiyana popanga ndi kupanga zida zamagetsi.
1. Njira Yowotcherera ya Laser Precision Spot ya Zipangizo Zowunikira Kwambiri
Polumikiza zinthu zowunikira kwambiri monga aluminiyamu ndi mkuwa, ma waveform osiyanasiyana olumikizirana amakhala ndi zotsatira zazikulu pa ubwino wa kulumikiza. Kugwiritsa ntchito ma waveform a laser okhala ndi pre-spike kumatha kuswa chotchinga chachikulu chowunikira. Mphamvu ya nthawi yomweyo ya peak yayitali imatha kusintha msanga momwe chitsulo chilili, ndikukweza kutentha kwake kufika pamalo osungunuka, motero kuchepetsa kuwunikira kwa pamwamba pa chitsulo ndikuwonjezera kugwiritsa ntchito mphamvu. Kuphatikiza apo, chifukwa cha kutentha kwachangu kwa zinthu monga mkuwa ndi aluminiyamu, kugwiritsa ntchito ma waveform owonongeka pang'onopang'ono kungathandize kukonza mawonekedwe a ma weld spots.
Kumbali ina, kuchuluka kwa kuyamwa kwa zinthu monga golide, siliva, mkuwa, ndi chitsulo kumachepa pamene kutalika kwa mafunde kukukwera. Pa mkuwa, pamene kutalika kwa mafunde a laser kuli 532nm, kuchuluka kwa kuyamwa kwa mkuwa kumakhala pafupi ndi 40%. Kusanthula koyerekeza kwa makhalidwe a ma laser a infrared ndi ma laser obiriwira kukuwonetsa kuti ma laser a infrared ali ndi kukula kwakukulu kwa malo, kuya kwafupikitsa kwa focal, ndi kuchuluka kochepa kwa kuyamwa ndi mkuwa wofiira; ma laser obiriwira ali ndi kukula kochepa kwa malo, kuya kwa focal kwakutali, ndi kuchuluka kwa kuyamwa ndi mkuwa wofiira. Pamene pulse spot welding ikuchitidwa pa mkuwa wofiira pogwiritsa ntchito ma laser a infrared ndi ma laser obiriwira motsatana, zimapezeka kuti kukula kwamalo osungunula pambuyo powunjikaKugwiritsa ntchito ma laser a infrared sikusinthasintha, pomwe mawanga opangidwa ndi ma laser obiriwira ndi ofanana kukula, kusinthasintha kwakuya, komanso kusalala pamwamba (Zithunzi 1-2). Kugwiritsa ntchito ma laser obiriwira kumapangitsa kuti pakhale zotsatira zokhazikika, ndipo mphamvu yofunikira kwambiri ndi yochepera theka kuposa ya ma laser a infrared.
2. Njira Yowotcherera ya Laser Precision Spot ya Zipangizo Zachitsulo Zopyapyala
Pamene ma laser achikhalidwe a millisecond amagwiritsidwa ntchito kulumikiza zinthu zopyapyala zachitsulo, zinthuzo zimakhala zosavuta kulowa ndipo mawanga olumikizira amakhala akuluakulu. Chifukwa cha kusakhazikika kwawo komanso kuchepa kwa kuyamwa kwa laser mu mkhalidwe wolimba, zinthu zowunikira kwambiri nthawi zambiri zimakhala ndi kufalikira, kusakwanira kuwotcherera, ndi zochitika zina panthawi yowotcherera. Kuti athetse mavuto owotcherera a mapepala opyapyala ndi zitsulo zowunikira kwambiri, analog ndi digital modulation zimachitika motsatana pa QCW/CW mode ya fiber lasers. Choyambitsa chimodzi chimatha kuzindikira kutulutsa kwa N pulse, ndikukwaniritsa single-point.kuwotcherera kwa ma pulse ambirindi mphamvu yotsika.
3. Njira Yowotcherera ya Laser Precision Spot ya Zipangizo Zosiyana
Pamene laser imagwiritsa ntchito zinthu zopyapyala zosiyana, mavuto monga kusakwanira kulumikiza, ming'alu, ndi mphamvu yochepa ya malumikizano amatha kuchitika. Izi zili choncho chifukwa zinthu ziwirizi zimakhala ndi kusiyana kwakukulu pa makhalidwe enieni, kusungunuka kochepa kwa mgwirizano, ndipo zimakhala ndi mwayi wopanga ma intermetallic compounds osalimba, zomwe zimachepetsa kwambiri mphamvu ya makina a welded joint. Kugwiritsa ntchito nanosecond laser yokhala ndi kuwala kwapamwamba kudzera mu high speed scanning kungathe kuwongolera bwino momwe kutentha kumalowera kuti kulepheretse mapangidwe a intermetallic compounds, kuzindikira lap welding ya ma lap steel sheet, ndikuwongolera mapangidwe a weld ndi mphamvu ya makina.
Mitundu Yodziwika ya Kuwotcherera Molondola
Kodi mitundu yodziwika bwino ya kuwotcherera kolondola ndi iti? Pankhani yowotcherera, mitundu yodziwika bwino ya kuwotcherera kolondola makamaka imaphatikizapo kuwotcherera kolimba kokana, kuwotcherera kwa laser, kuwotcherera kwa ultrasonic, ndi kuwotcherera kwa micro arc spot. Chifukwa cha mawonekedwe apadera a laser, poyerekeza ndi njira zina zowotcherera, kuwotcherera kolondola kwa laser kuli ndi ubwino wochita bwino kwambiri, kusamala chilengedwe, komanso kulondola kwambiri pokonza.
Kugwiritsa Ntchito Kwambiri kwa Laser Precision Spot Welding
Kodi kuwotcherera malo olondola a laser kumagwiritsidwa ntchito kuti makamaka? Pakadali pano, kuwotcherera malo olondola a laser kungagwiritsidwe ntchito kuwotcherera molondola zinthu zosiyanasiyana zazing'ono komanso zotentha monga zodzikongoletsera, machesi a tsitsi a wotchi, ndi ma waya olumikizidwa. Ndikoyenera mafakitale monga zida zamagetsi, zamagetsi, kulumikizana, makina, magalimoto, makampani ankhondo, ndi zodzikongoletsera zagolide. Monga mtundu wa kuwotcherera laser, kuwotcherera malo olondola a laser ndi njira yatsopano yowotcherera. Poyerekeza ndi kuwotcherera malo olondola achikhalidwe, kuwotcherera malo olondola a laser kuli ndi ubwino wake wapadera. Pogwiritsa ntchito laser ngati gwero la kutentha, kuwotcherera malo kumakhala kofulumira, kolondola, kokhala ndi kutentha kochepa komanso kusintha pang'ono kwa ntchito. Ma laser ali ndi mwayi wopezeka mosavuta, womwe ungachepetse zoletsa za malo ndi kapangidwe kake panthawi yowotcherera malo. Safuna zida zambiri zothandizira, amatha kusintha mwachangu kusintha kwa zinthu, ndikukwaniritsa zosowa zamsika. Ndi chitukuko chachangu chachuma cha China komanso kupita patsogolo kosalekeza kwa mulingo wa sayansi ndi ukadaulo, chitukuko chaUkadaulo wowotcherera malo molondola pogwiritsa ntchito laseryapita patsogolo mwachangu. Chifukwa cha ubwino wake wowotcherera bwino komanso kuthamanga kwambiri, yagwiritsidwa ntchito kwambiri pokonza zinthu zopyapyala zachitsulo.
Ubwino wa Kuwotcherera Mwanzeru kwa Laser
Choyamba, tiyeni timvetse ubwino wa kuwotcherera kolondola kwa laser:
- Imatha kulumikiza njira zosiyanasiyana. Ma laser ali ndi njira yolunjika bwino, zomwe zimapangitsanso zotsatira zabwino pakulumikiza zinthu zosakhazikika.
- Kuwotcherera kolimba. Pambuyo poyang'ana kwambiri, malo owunikira laser amakhala ochepa komanso amphamvu kwambiri, zomwe zimapangitsa kuti mtandawo upange malo otentha pakapita nthawi yochepa kwambiri. Pambuyo posungunuka, kuzizira, ndi kupangika kwa crystallization, msoko wolimba ndi malo owunikira zimapangidwa.
- Kulondola kwambiri pakuwotcherera. Kugawidwa kwa mphamvu ya laser kuli ndi mawonekedwe a nthawi ndi malo, zomwe zimapangitsa kuti mtandawo ugawidwe m'njira zingapo zowunikira kuti zigwiritsidwe ntchito nthawi imodzi, zomwe zimapereka chitsimikizo champhamvu cha kulondola kwa kuwotcherera.
- Liwiro la kuwotcherera mwachangu. Ukadaulo wa laser umaphatikizidwa ndi ukadaulo wa CNC wa makompyuta. Ponena za kuzindikira zida zofunika komanso makina owongolera mayendedwe, kuphatikiza kwa makina kumaphatikizapo kuzindikira nthawi yeniyeni ndi kukonza mayankho, zomwe zimathandizira liwiro la kukonza chidziwitso cha makina ndikuwonjezera magwiridwe antchito a makinawo.
