Laser processing kuwala dongosolo yankho
Kutsimikiza kwakukonza kwa laserNjira yothetsera vuto la makina owonera imadalira momwe zinthu zilili pa ntchito inayake. Zochitika zosiyanasiyana zimapangitsa kuti pakhale njira zosiyanasiyana zothetsera vuto la makina owonera. Kusanthula kwapadera kumafunika pa ntchito zinazake. Dongosolo la makina owonera likuwonetsedwa mu Chithunzi 1:

Njira yoganizira ndi iyi: zolinga zenizeni za ndondomeko -lasermakhalidwe - kapangidwe ka dongosolo la kuwala - kukwaniritsa zolinga zomaliza. Izi ndi magawo osiyanasiyana ogwiritsira ntchito:
1. Malo okonzera zinthu zazing'ono molondola (kulemba, kupukuta, kuboola, kudula kolondola, ndi zina zotero) Njira zodziwika bwino m'munda wokonzera zinthu zazing'ono molondola ndi kukonza zinthu zazing'ono pogwiritsa ntchito zinthu monga zitsulo, zoumba, ndi galasi, monga kuyika chizindikiro cha mafoni am'manja, ma stenti azachipatala, mabowo ang'onoang'ono a nozzles zolowetsa mafuta a gasi, ndi zina zotero. Chofunika kwambiri pakukonzekera ndi ichi: choyamba, chiyenera kukwaniritsa malo ochepa kwambiri owunikira, kuchuluka kwa mphamvu zambiri, ndi malo ochepa kwambiri otenthetsera kutentha, ndi zina zotero. Pa ntchito ndi zofunikira zomwe zili pamwambapa, kusankha ndi kupangamagwero a kuwala kwa laserndi zigawo zina zimachitidwa.
a. Kusankha laser: Laser yolimba ya ultraviolet/green (nanosecond) kapena ultrafast laser (picosecond, femtosecond) yomwe imakonda kwambiri imachitika chifukwa cha zifukwa ziwiri. Choyamba ndi chakuti kutalika kwa wavelength kumagwirizana ndi malo owunikira, ndipo nthawi zambiri kutalika kwa wavelength kochepa kumasankhidwa. Chachiwiri ndi chakuti ma pulse a picosecond/femtosecond ali ndi khalidwe la "kukonza kozizira", ndipo mphamvu imamalizidwa kukonza kutentha kusanayambe, zomwe zimapangitsa kuti kuzizira kuchitike. Kawirikawiri, gwero la kuwala la laser lomwe limatulutsa kuwala kwa malo limasankhidwa, lomwe nthawi zambiri limakhala ndi beam quality factor M2 yochepera 1.1, yokhala ndi beam quality yabwino kwambiri.
b. Dongosolo lokulitsa denga ndi dongosolo lokulitsa nthawi zambiri limagwiritsa ntchito magalasi okulitsa denga osinthika (2X - 5X), kuyesera kuwonjezera mtunda wa denga momwe zingathere. M'mimba mwake wa denga umagwirizana mosiyanasiyana ndi malo owunikira, ndipo kapangidwe kake kokulitsa denga la Galilean nthawi zambiri kamagwiritsidwa ntchito.
c. Dongosolo loyang'ana nthawi zambiri limagwiritsa ntchito magalasi a F-Theta opambana kwambiri (powasanthula) kapena magalasi oyang'ana a telecentric. Kutalika kwa focal kumakhala kofanana ndi malo owunikira olunjika, ndipo nthawi zambiri magalasi afupiafupi a focal field (monga f = 50mm, 100mm) amagwiritsidwa ntchito. Monga momwe zasonyezedwera pa Chithunzi 1: Nthawi zambiri, lens ya field imagwiritsa ntchito gulu la magalasi okhala ndi zinthu zambiri (chiwerengero cha magalasi ≥ 3), chomwe chingapangitse kuti malo owonera awonekere kwambiri, kutsegula kwakukulu, komanso zizindikiro zochepa zosokoneza. Ma lens owonera pano onse ayenera kuganizira za malire a kuwonongeka kwa laser.
d. Dongosolo la kuwala loyang'anira Coaxial: Mu dongosolo la kuwala, dongosolo la coaxial vision (CMOS) nthawi zambiri limaphatikizidwa kuti liyike bwino malo ndikuwunika nthawi yeniyeni njira yogwirira ntchito.
2. Kukonza zinthu zazikulu Nthawi zambiri ntchito yokonza zinthu zazikulu imaphatikizapo kudula mapepala a magalimoto, kuwotcherera mbale zachitsulo za sitima, ndi kuwotcherera zipolopolo za batire. Njirazi zimafuna mphamvu zambiri, mphamvu zambiri zolowera, kugwira ntchito bwino, komanso kukhazikika kwa ntchito.
3. Kupanga zowonjezera za laser (kusindikiza kwa 3D) ndi kupanga zowonjezera za laser (kusindikiza kwa 3D) ndi kugwiritsa ntchito zophimba nthawi zambiri kumakhala ndi njira zotsatirazi: kusindikiza zitsulo zovuta pamlengalenga, kukonza tsamba la injini, ndi zina zotero.
Kusankha zigawo zazikulu ndi motere:
a. Kusankha laser: Kawirikawiri,ma laser amphamvu kwambiriamasankhidwa, ndipo mphamvu yake nthawi zambiri imapitirira 500W.
b. Kupanga matabwa: Dongosolo la kuwalali liyenera kutulutsa kuwala kosalala pamwamba, kotero kupanga matabwa ndiye ukadaulo waukulu, ndipo ukhoza kuchitika pogwiritsa ntchito zinthu zowunikira zotulutsa kuwala.
c. Dongosolo Loyang'ana: Magalasi ndi kuyang'ana mozama ndizofunikira kwambiri pa ntchito yosindikiza ya 3D. Nthawi yomweyo, lenzi yowunikira iyenera kugwiritsa ntchito kapangidwe ka telecentric ka mbali imodzi kuti iwonetsetse kuti zinthu zikuyenda bwino m'mphepete ndi pakati.
