Mu gawo la ma optics olondola ndi metrology, kupeza malo okhazikika komanso opanda kugwedezeka ndiye maziko a muyeso wodalirika. Pakati pa machitidwe onse othandizira omwe amagwiritsidwa ntchito m'ma laboratories ndi m'malo opangira mafakitale, nsanja yoyandama ya mpweya wowala—yomwe imadziwikanso kuti tebulo lodzipatula la kugwedezeka kwa kuwala—imagwira ntchito yofunika kwambiri pakuwonetsetsa kuti zida monga ma interferometer, ma laser system, ndi makina oyezera ogwirizana (CMMs) ndi zolondola kwambiri.
Kapangidwe ka Uinjiniya wa Optical Platform
Pulatifomu yapamwamba kwambiri yowunikira imakhala ndi kapangidwe ka uchi wachitsulo chonse, kopangidwa kuti kakhale kolimba komanso kokhazikika pa kutentha. Mapepala apamwamba ndi pansi, omwe nthawi zambiri amakhala 5 mm makulidwe, amalumikizidwa ku chipolopolo cha uchi chopangidwa bwino chopangidwa ndi mapepala achitsulo a 0.25 mm, kupanga kapangidwe kofanana komanso kosiyana. Kapangidwe kameneka kamachepetsa kukula ndi kupindika kwa kutentha, kuonetsetsa kuti nsanjayo imakhala yosalala ngakhale kutentha kusinthasintha.
Mosiyana ndi aluminiyamu kapena zigawo zamkati, kapangidwe ka uchi wachitsulo kamapereka kuuma kosalekeza mkati mwake, popanda kuyambitsa kusintha kosafunikira. Makoma am'mbali amapangidwanso ndi chitsulo, zomwe zimathandiza kuthetsa kusakhazikika komwe kumabwera chifukwa cha chinyezi—vuto lomwe nthawi zambiri limapezeka m'mapulatifomu opangidwa ndi zinthu zosakanikirana. Pambuyo pomaliza ndi kupukuta pamwamba pa chinthu chokha, pamwamba pa tebulo pamakhala kusalala kwa sub-micron, zomwe zimapangitsa kuti malo abwino kwambiri azigwiritsidwa ntchito popanga zinthu zowunikira komanso zida zolondola.
Kuyesa Molondola ndi Kuyesa Kutsatira Malamulo
Asanachoke ku fakitale, nsanja iliyonse yoyandama ya mpweya wowala imayesedwa kugwedezeka ndi kutsata malamulo osiyanasiyana. Nyundo ya pulse imagwiritsa ntchito mphamvu yolamulidwa pamwamba pa nsanjayo pomwe masensa amalemba momwe kugwedezeka kumachitikira. Zizindikirozo zimasanthulidwa kuti zipange ma frequency response spectrum, zomwe zimathandiza kudziwa momwe nsanjayo imagwirira ntchito komanso momwe imagwirira ntchito.
Miyeso yofunika kwambiri imatengedwa kuchokera kumakona anayi a nsanjayi, chifukwa mfundo izi zikuyimira vuto lalikulu kwambiri lotsata malamulo. Chogulitsa chilichonse chimaperekedwa ndi ndondomeko yodziyimira payokha yotsatizana ndi lipoti la magwiridwe antchito, kuonetsetsa kuti mawonekedwe a nsanjayi akuwonekera bwino. Mlingo uwu wa mayeso umaposa machitidwe achikhalidwe amakampani, zomwe zimapatsa ogwiritsa ntchito kumvetsetsa mwatsatanetsatane machitidwe a nsanjayi pansi pa mikhalidwe yeniyeni yogwirira ntchito.
Udindo wa Kudzipatula kwa Kugwedezeka
Kudzipatula kwa kugwedezeka ndi gawo lofunika kwambiri pakupanga nsanja yowunikira. Kugwedezeka kumachokera ku magwero awiri akuluakulu—kunja ndi mkati. Kugwedezeka kwakunja kumachokera pansi, monga mapazi, makina oyandikana nawo, kapena kumveka kwa kapangidwe kake, pomwe kugwedezeka kwamkati kumachokera ku kuyenda kwa mpweya, makina ozizira, ndi ntchito ya chipangizocho.
Pulatifomu yowunikira yoyandama mpweya imasiyanitsa mitundu yonse iwiri. Miyendo yake yoyimitsira mpweya imayamwa ndikuchepetsa kugwedezeka kwakunja komwe kumadutsa pansi, pomwe gawo lonyowa la mpweya pansi pa tebulo limasefa phokoso lamkati la makina. Pamodzi, amapanga maziko chete komanso okhazikika omwe amatsimikizira kulondola kwa miyeso ndi zoyeserera zolondola kwambiri.
Kumvetsetsa Kuchuluka kwa Zachilengedwe
Dongosolo lililonse la makina lili ndi ma frequency achilengedwe—ma frequency omwe limakonda kugwedezeka likasokonezedwa. Gawoli limalumikizidwa kwambiri ndi kulemera ndi kuuma kwa dongosololi. Mu makina olekanitsa kuwala, kusunga ma frequency achilengedwe otsika (nthawi zambiri pansi pa 2–3 Hz) ndikofunikira kwambiri, chifukwa kumalola tebulolo kuti lilekanitse kugwedezeka kwa chilengedwe bwino m'malo mokulikulitsa. Kugwirizana pakati pa kulemera, kuuma, ndi kunyowa kumatsimikizira mwachindunji momwe dongosololi limagwirira ntchito komanso kukhazikika kwake.
Ukadaulo wa Pulatifomu Yoyandama Mlengalenga
Mapulatifomu amakono oyandama a mpweya akhoza kugawidwa m'magulu a XYZ linear air bearing stages ndi mapulatifomu ozungulira air bearing. Pakati pa machitidwe awa ndi njira yonyamulira mpweya, yomwe imapereka kayendedwe kosasunthika komwe kamathandizidwa ndi filimu yopyapyala ya mpweya wopanikizika. Kutengera ndi momwe imagwiritsidwira ntchito, mabearing a mpweya akhoza kukhala athyathyathya, a linear, kapena a spindle.
Poyerekeza ndi malangizo owongolera a makina, ma air bearing amapereka kulondola kwa kayendedwe ka micron-level, kubwerezabwereza kwapadera, komanso kusagwiritsidwa ntchito konse kwa makina. Amagwiritsidwa ntchito kwambiri poyang'anira ma semiconductor, photonics, ndi nanotechnology, komwe kulondola kwa sub-micron ndi kukhazikika kwa nthawi yayitali ndikofunikira.
Kusamalira ndi Kukhala ndi Moyo Wautali
Kusunga malo oyandama a mpweya wowala n'kosavuta koma kofunikira. Sungani pamwamba pa nthaka kukhala paukhondo komanso popanda zinyalala, nthawi ndi nthawi yang'anani mpweya womwe uli m'malo opumira kuti muwone ngati uli ndi chinyezi kapena kuipitsidwa, komanso pewani kugunda kwambiri tebulo. Ngati tebulo lowala bwino lisamalidwe bwino, limatha kugwira ntchito modalirika kwa zaka zambiri popanda kuwonongeka.
