Kutsegula Maziko a Granite: Momwe Mungatsekere Kulondola kwa ±0.5μm Pobwerezabwereza Malo Omwe Mungadulire Magalasi a Smartphone.

Pakupanga mafoni anzeru, kulondola kwa kudula magalasi ndikofunikira kwambiri, ndipo maziko a granite akukhala ofunikira kwambiri pakutsimikizira kulondola kumeneku. Ndi zinthu zake zapadera komanso kugwiritsa ntchito ukadaulo wapamwamba, imakwaniritsa kulondola kobwerezabwereza kwa ±0.5μm, zomwe zimapangitsa kuti kudula magalasi kwa mafoni anzeru kukhale kolondola kwambiri.
Ubwino wa zinthu zakuthupi ndi umene umakhazikitsa maziko a kulondola
Granite ili ndi kuchuluka kochepa kwambiri kwa kutentha komwe kumawonjezeka. Khalidweli limapangitsa kuti kukula kwake kusasinthe kwambiri kutentha kukasintha. Panthawi yodula magalasi a mafoni, ntchito ya chipangizocho imapanga kutentha, ndipo kutentha kwa malo ozungulira kungasinthenso. Maziko wamba a zinthu amatha kusokonekera chifukwa cha kukula kwa kutentha ndi kupindika, zomwe zimakhudza kulondola kwa kudula. Maziko a granite amatha kuletsa kusinthaku ndikuwonetsetsa kuti malo aliwonse a chipangizocho akukhazikika. Mwachitsanzo, mkati mwa maola angapo otsatizana a ntchito zodula mwamphamvu, ngakhale kutentha kwamkati kwa chipangizocho kukwera ndi 10℃, kusintha kwa gawo la granite kumatha kulamulidwa pamlingo wa nanometer, popanda kusokoneza kulondola kwa kudula.

Kuphatikiza apo, kapangidwe ka mkati mwa granite ndi kolimba komanso kofanana, kolimba kwambiri, ndipo kali ndi kukana kugwedezeka komanso kutopa kwambiri. Kugwedezeka komwe kumachitika panthawi yodulira komanso kukangana kwa zigawo monga njanji zowongolera panthawi yogwiritsidwa ntchito kwa nthawi yayitali n'kovuta kuwononga kwambiri maziko a granite. Imatha kuyamwa ndikuletsa kugwedezeka kwakunja, kuletsa kugwedezeka kuti kusapitirire ku chida chodulira, kuonetsetsa kuti njira yodulirayo ikuyenda bwino, ndikupanga malo ogwirira ntchito okhazikika kuti akwaniritse malo obwerezabwereza molondola kwambiri.
Yothandizidwa ndi njira zolondola zopangira
Kudzera mu njira zamakono zopangira, zizindikiro zazikulu monga kusalala ndi kulunjika kwa maziko a granite zimayendetsedwa mkati mwa mtunda wochepa kwambiri. Pakukonza, njira zopukutira ndi kupukuta bwino zimagwiritsidwa ntchito kuti pakhale kusalala kwakukulu pamwamba pa maziko, ndipo kulekerera kusalala kumatha kulamulidwa mkati mwa ± 0.5μm. Mwanjira imeneyi, njanji zowongolera za zida zodulira zomwe zayikidwa pansi zimatha kusunga kuyenda kolondola, kupereka maziko odalirika a malo olondola a mutu wodulira.

Pakadali pano, panthawi yopangira maziko ndi zida zina zodulira, njira zolondola kwambiri zoyikira ndi zomangira zinagwiritsidwa ntchito. Malo aliwonse olumikizirana adakonzedwa bwino kuti zitsimikizire malo olondola pakati pa zidazo. Kudzera mu kukhazikitsa kolondola kwa bolt ndi pini yoyikira, mutu wodulira, njira yotumizira, ndi zina zotero zimalumikizidwa kwambiri ku maziko a granite, kuchotsa mipata ndi kusasunthika kulikonse komwe kungatheke, motero kuonetsetsa kuti kulondola kumachitika panthawi yoyikira mobwerezabwereza.
Machitidwe apamwamba ozindikira ndi kulamulira amagwira ntchito mogwirizana
Kuti tikwaniritse kulondola kobwerezabwereza kwa ±0.5μm, maziko a granite amalumikizidwanso kwambiri ndi makina apamwamba ozindikira ndi owongolera. Masensa olondola kwambiri monga ma grating rulers kapena ma magnetic grating rulers amayikidwa pazida zodulira. Amawunika malo a mutu wodulira nthawi yeniyeni ndikubwezera deta ku makina owongolera. Mutu wodulira ukamaliza ntchito imodzi yodulira ndipo wakonzeka kuyiyikanso, makina owongolera adzayerekeza deta yomwe sensor imalandira ndi malo omwe adakonzedweratu.

Akangozindikira kuti pali kusintha kwa malo, makina owongolera nthawi yomweyo amapereka malangizo oti ayendetse mota ya servo yolondola kwambiri kuti akonze bwino malo a mutu wodula. Ntchito yonseyi imatha munthawi yochepa kwambiri, zomwe zimathandiza kuti mutu wodula usinthidwe mwachangu komanso molondola pamalo omwe mukufuna, ndikukwaniritsa kulondola kwa malo obwerezabwereza a ±0.5μm. Kuphatikiza apo, makina owongolera otsekedwa awa amatha kuphunzira ndikuwongolera mosalekeza. Pamene nthawi yogwiritsira ntchito ikuwonjezeka, kulondola ndi kukhazikika kwa malo obwerezabwereza kumawonjezeka.

Pankhani yodula magalasi a mafoni anzeru, maziko a granite akwanitsa bwino kulondola kobwerezabwereza kwa ±0.5μm chifukwa cha ubwino wawo, njira zolondola zopangira, komanso mphamvu yogwirizana ya makina apamwamba ozindikira ndi kulamulira. Izi sizimangowonjezera ubwino ndi magwiridwe antchito a kudula magalasi a mafoni anzeru, komanso zimapereka chithandizo champhamvu pakukula kolondola kwa makampani onse opanga mafoni anzeru.
