![Ubwino ndi mawonekedwe apamwamba a UV laser micro-machining 1]()
M'zaka 10 zapitazi, njira ya laser idayambitsidwa pang'onopang'ono m'magawo opanga mafakitale osiyanasiyana ndipo imakhala yotchuka kwambiri. Laser chosema, laser kudula, laser kuwotcherera, kubowola laser, kuyeretsa laser ndi njira zina laser chimagwiritsidwa ntchito zitsulo nsalu, malonda, chidole, mankhwala, galimoto, ogula zamagetsi, kulankhulana, shipbuilding, Azamlengalenga ndi mbali zina.
Jenereta ya laser imatha kugawidwa m'mitundu yosiyanasiyana kutengera mphamvu ya laser, kutalika kwa mafunde ndi dziko. Mwa kutalika kwa mafunde, laser infrared ndiye mtundu womwe umagwiritsidwa ntchito kwambiri, makamaka pakukonza zitsulo, magalasi, zikopa ndi nsalu. Green laser amatha kuchita laser chodetsa ndi chosema pa galasi, kristalo, akiliriki ndi zipangizo zina mandala. Laser UV, komabe, imatha kutulutsa bwino kwambiri ndikudula komanso kuyika chizindikiro papulasitiki, phukusi la bokosi lamapepala, zida zamankhwala ndi zamagetsi ogula ndipo limakhala lodziwika kwambiri.
Kuchita kwa UV laser
Pali mitundu iwiri ya lasers UV. Imodzi ndi yolimba-state UV laser ndipo ina ndi gas UV laser. Laser ya gasi UV imadziwikanso kuti excimer laser ndipo imatha kupangidwanso kukhala laser yoopsa kwambiri ya UV yomwe ingagwiritsidwe ntchito mu cosmetology yachipatala ndi stepper chomwe ndi chida chofunikira popanga madera ophatikizika.
Laser yokhazikika ya UV ili ndi kutalika kwa 355nm ndipo imakhala ndi kugunda kwakufupi, kuwala kwabwino kwambiri, kulondola kwambiri komanso nsonga yapamwamba kwambiri. Poyerekeza ndi laser wobiriwira ndi infuraredi laser, UV laser ili ndi kutentha kochepa komwe kumakhudza madera ndipo imakhala ndi mayamwidwe abwinoko mumitundu yosiyanasiyana yazinthu. Chifukwa chake, laser ya UV imatchedwanso "gwero la kuwala kozizira" ndipo kukonza kwake kumadziwika kuti "cold processing."
Ndi chitukuko chachangu cha njira yaufupi ya laser pulsed laser, olimba-state picosecond UV laser ndi picosecond UV fiber laser akhala okhwima kwambiri ndipo amatha kukwaniritsa mwachangu komanso molondola kwambiri. Komabe, popeza picosecond UV laser ndiyokwera mtengo kwambiri, ntchito yayikulu ikadali nanosecond UV laser.
Kugwiritsa ntchito laser UV
Laser ya UV ili ndi mwayi womwe magwero ena a laser alibe. Ikhoza kuchepetsa kupsinjika kwa kutentha, kuti kuwonongeka kochepa kuchitike pa ntchito yomwe idzakhalabe. UV laser akhoza kukhala ndi wosangalatsa processing zotsatira pa zinthu zoyaka moto, zinthu zolimba ndi Chimaona, ziwiya zadothi, galasi, pulasitiki, pepala ndi mitundu yosiyanasiyana ya zinthu sanali zitsulo.
Kwa pulasitiki yofewa komanso ma polima apadera omwe amagwiritsidwa ntchito popanga FPC amatha kukhala opangidwa ndi laser ya UV m'malo mwa laser infrared.
Ntchito ina ya UV laser ndikubowola yaying'ono, kuphatikiza kudzera mu dzenje, dzenje laling'ono ndi zina zotero. Poyang'ana kuwala kwa laser, laser ya UV imatha kudutsa pa bolodi kuti ikwaniritse kubowola. Kutengera ndi zida zomwe laser laser amagwiritsa ntchito, dzenje laling'ono kwambiri lobowola limatha kukhala lochepera 10μm.
Ceramics akhala akusangalala zaka zikwi zingapo za mbiriyakale. Kuchokera pazogwiritsidwa ntchito tsiku ndi tsiku mpaka zamagetsi, mutha kuwona zotsalira za ceramic. Zaka zana zapitazi, zida zamagetsi zamagetsi pang'onopang'ono zidakula ndipo zidakhala ndi ntchito zambiri, monga bolodi lotayira kutentha, zida za piezoelectric, semiconductor, kugwiritsa ntchito mankhwala ndi zina zotero. Monga zida zamagetsi zamagetsi zimatha kuyamwa bwino kuwala kwa laser ya UV ndipo kukula kwake kumakhala kocheperako komanso kocheperako, laser ya UV imamenya laser ya CO2 ndi laser yobiriwira pakupanga makina ang'onoang'ono pamagetsi amagetsi.
Ndikusintha mwachangu kwamagetsi ogula, kufunikira kwa kudula bwino, kuzokota ndikuyika chizindikiro pazida ndi magalasi kudzakula kwambiri, ndikupangitsa chitukuko chachikulu cha laser yapakhomo ya UV. Malinga ndi kafukufukuyu, kuchuluka kwa malonda a laser yapanyumba ya UV kupitilira mayunitsi 15000 chaka chatha ndipo pali opanga ambiri otchuka a UV laser ku China. Kutchula ochepa: Pezani Laser, Inngu, Inno, Bellin, RFH, Huaray ndi zina zotero.
UV laser yozizira unit
Masiku ano mafakitale amagwiritsa ntchito laser laser kuyambira 3W mpaka 30W. Kufuna kukonza mwatsatanetsatane kumafuna kuwongolera kutentha kwa UV laser. Kuti muwonetsetse kudalirika komanso moyo wa laser wa UV, kuwonjezera chida chokhazikika komanso choziziritsa chapamwamba ndi CHOFUNIKA.
S&A Teyu ndiwopereka njira yoziziritsira laser kwa zaka 19 za mbiri yakale ndi kuchuluka kwa malonda apachaka a mayunitsi 80000. Kwa laser yozizira ya UV, S&A Teyu adapanga RMUP mndandanda wa rack mount recirculating water chiller omwe kutentha kwake kumafika ± 0.1 ℃. Itha kuphatikizidwa mu kapangidwe ka makina a UV laser.
