Kodi makina olembera laser ali ndi makhalidwe otani?

Makina olembera a laser amagwiritsidwa ntchito kulemba pamwamba pa zinthu zosiyanasiyana nthawi zonse ndi kuwala kwa laser. Zotsatira zake ndi kudzera mu kusungunuka kwa zinthu zakuthwa zomwe zili pamwamba, kuti apange mapangidwe okongola, zizindikiro ndi mawu, makina olembera a laser amagawidwa makamaka m'magulu awiri: makina olembera a laser a CO2, makina olembera a laser a semiconductor, makina olembera a laser a fiber ndi makina olembera a laser a YAG, makina olembera a laser amagwiritsidwa ntchito makamaka pazinthu zina zabwino kwambiri komanso zolondola kwambiri. Amagwiritsidwa ntchito muzinthu zamagetsi, ma circuit ophatikizidwa (IC), zida zamagetsi, kulumikizana kwa mafoni am'manja, zinthu za hardware, zida ndi zowonjezera, zida zolondola, mawotchi ndi mawotchi a magalasi, zodzikongoletsera, zowonjezera zamagalimoto, makiyi apulasitiki, zipangizo zomangira, chitoliro cha PVC.

Kodi makina olembera laser ali ndi makhalidwe otani? Pali mfundo ziwiri zodziwika bwino: "kukonza kutentha" kumakhala ndi mphamvu zambiri za kuwala kwa laser (ndi mphamvu yochulukirapo), kuwala pamwamba pa zinthu zomwe zakonzedwa, pamwamba pa zinthuzo kumayamwa mphamvu ya laser, njira yotenthetsera kutentha m'dera lotenthetsera, kotero kuti kutentha kwa pamwamba pa zinthuzo (kapena zokutira) kukwera, kupanga zinthu zosazolowereka, kusungunuka, kuchotsedwa kwa mpweya, kutuluka kwa madzi ndi zina zotero.

"Kugwira ntchito kozizira" kuli ndi mphamvu zambiri za ma photon (ultraviolet), omwe amatha kuswa ma bond a mankhwala muzinthu (makamaka zinthu zachilengedwe) kapena zozungulira mpaka kufika powononga zinthuzo popanda kutentha. Mtundu uwu wa kukonza kozizira uli ndi kufunika kwapadera pakupanga ma label a laser, chifukwa si kutentha, koma sikubweretsa zotsatira zoyipa za "kuwonongeka kwa kutentha", kuswa kuzizira kwa ma bond a mankhwala, kotero gawo lamkati la pamwamba lokonzedwa ndi dera lapafupi silipanga kutentha kapena kusintha kwa kutentha. Mwachitsanzo, ma laser a excimer amagwiritsidwa ntchito mumakampani amagetsi kuti ayike mafilimu opyapyala a mankhwala pa substrate, ndikupanga mipata yopapatiza mu substrate ya semiconductor.

Kuyerekeza njira zosiyanasiyana zolembera Poyerekeza ndi njira yolembera inkjet, kujambula pogwiritsa ntchito laser kuli ndi ubwino wogwiritsa ntchito zinthu zosiyanasiyana (chitsulo, galasi, zoumba, mapulasitiki, zikopa, ndi zina zotero) zitha kulembedwa ndi khalidwe labwino kwambiri. Palibe mphamvu pamwamba pa workpiece, palibe kusintha kwa makina, kapena palibe dzimbiri pamwamba pa zinthuzo.

Kugwiritsa ntchito mankhwalawa kumatha kuumba zinthu zosiyanasiyana zopanda chitsulo. Kumagwiritsidwa ntchito muzowonjezera zovala, ma CD a mankhwala, ma CD a vinyo, zomangira zadothi, ma CD a zakumwa, kudula nsalu, zinthu za rabara, chipolopolo cha chipolopolo, mphatso zaluso, zida zamagetsi, zikopa ndi mafakitale ena. 1. Kumatha kuumba zitsulo ndi zinthu zosiyanasiyana zopanda chitsulo. Zoyenera kwambiri pazinthu zina zokonza zinthu bwino komanso zolondola kwambiri. 2. Kugwiritsidwa ntchito muzinthu zamagetsi, ma circuit ophatikizidwa (IC), zida zamagetsi, kulumikizana kwa mafoni am'manja, zinthu za hardware, zida ndi zowonjezera, zida zolondola, mawotchi ndi mawotchi a magalasi, zodzikongoletsera, zowonjezera zamagalimoto, makiyi apulasitiki, zipangizo zomangira, chitoliro cha PVC, zida zamankhwala ndi mafakitale ena. 3. Zipangizo zomwe zimagwiritsidwa ntchito ndi izi: Zitsulo ndi zinthu zina zodziwika bwino (chitsulo, mkuwa, aluminiyamu, magnesium, zinki ndi zitsulo zina zonse), zitsulo ndi zinthu zina zosowa (golide, siliva, titaniyamu), zitsulo zouma (mitundu yonse ya zitsulo zouma ndizovomerezeka), mankhwala apadera pamwamba (phosphating, aluminiyamu anodizing, electroplating surface), zipangizo za ABS (chipolopolo cha zinthu zamagetsi, zofunikira za tsiku ndi tsiku), inki (makiyi owonekera, zinthu zosindikizira), Epoxy resin (encapsulation, insulating layer ya zida zamagetsi).
