Maitiro ekutsanangura iyo chaiyo nanopositioning system

Izvo zvinhu zvitanhatu zvekufunga nezve nanopositioning yakakwana

Kana usati wamboshandisa nanopositioning system, kana uine chikonzero chekutsanangura imwe kwechinguva, saka zvakakodzera kutora nguva yekufunga zvimwe zvezvinhu zvakakosha zvinoita kuti ubudirire kutenga.Izvi zvinhu zvinoshanda kune zvese zvikumbiro mukugadzirwa kwemaindasitiri, sainzi netsvagiridzo, mafotonic uye satellite instrumentation.

1.Kuvaka nanopositioning zvishandiso

Sainzi ye nanopositioning, ine yakasarudzika resolution mune nanometer uye sub-nanometer renji, uye mazinga ekupindura akayerwa mumadiki-milliseconds, anoenderana zvakanyanya nekugadzikana, nemazvo uye kudzokorora kwemakanika uye yemagetsi tekinoroji inoshandiswa mune yega yega system.

Chinhu chekutanga chakakosha kutariswa pakusarudza hurongwa hutsva hunofanirwa kunge huri hutano hwekugadzirwa kwayo nekugadzira.Precision engineering uye kutarisisa kune zvakadzama zvichave pachena, zvichiratidzwa munzira dzekuvaka, zvinhu zvinoshandiswa uye marongerwo ezvikamu zvechikamu zvakaita sematanho, sensors, cabling uye flexure.Izvi zvinofanirwa kugadzirwa kuti zvigadzire chimiro chakasimba uye chakasimba, chisina kuchinjika uye kukanganisa pasi pekumanikidzwa kana panguva yekufamba, kupindira kubva kune mamwe masosi, kana mhedzisiro yezvakatipoteredza sekuwedzera kwekupisa uye kuputika.

Iyo sisitimu inofanirwawo kugadzirwa kuti isangane nezvinodiwa zvechikumbiro chega chega;semuenzaniso, mamiriro ezvinhu pasi peiyo hurongwa hunoshandiswa pakutarisa kwekutarisa kweiyo semiconductor wafers ichange iine akasiyana zvachose maitiro ekushandisa kune anotarisirwa kushandiswa munzvimbo dze Ultra-yakakwirira vacuum kana yakakwira mwaranzi.

2.The motion profile

Pamusoro pekunzwisisa zvinodikanwa zvechishandiso, zvakakoshawo kufunga nezve mafambiro anozodiwa.Izvi zvinofanirwa kuverengerwa:

Urefu hunodiwa hwesitiroko kune imwe neimwe akisi yekufamba
 Nhamba uye musanganiswa wemademo ekufamba: x, y uye z, pamwe netip uye tilt
Kumhanya kwekufamba
Dynamic motion: semuenzaniso, kudiwa kwekutarisa mumativi ese ari maviri paaxis yega yega, chinodiwa chekufamba chisingaperi kana kutsika, kana mukana wekutora mifananidzo panhunzi;kureva kuti chiridzwa chakabatanidzwa chichiri kufamba.

3.Frequency mhinduro

Frequency kupindura chiratidzo chekumhanya kunoita mudziyo pakupindura chiratidzo chekupinda panguva yakapihwa.Piezo masisitimu anopindura nekukurumidza kukuraira masaini, ane yakakwirira resonant frequency inoburitsa nekukurumidza mhinduro mareti, kugadzikana kukuru uye bandwidth.Inofanira kuonekwa, zvisinei, kuti resonant frequency ye nanopositioning device inogona kukanganiswa nemutoro wakaiswa, nekuwedzera kwemutoro unoderedza resonant frequency uye nokudaro kukurumidza uye kururamisa kwe nanopositioner.

4.Kugadzirisa uye kusimuka nguva

Nanopositioning masisitimu anofambisa zvinhambwe zvidiki zvakanyanya, nekumhanya kwakanyanya.Izvi zvinoreva kuti kugadzirisa nguva kunogona kuve chinhu chakakosha.Uhwu ndihwo hurefu hwenguva hunotora kuti kufamba kudzikire kusvika padanho rinogamuchirika mufananidzo kana kuyerwa kusati kwatorwa.

Kana tichienzanisa, nguva yekusimuka ndiyo nguva yakapfuura yekuti nanopositioning nhanho ifambe pakati pemapoinzi maviri emirairo;izvi zvinowanzokurumidza kukurumidza kupfuura nguva yekugadzirisa uye, zvinonyanya kukosha, hazvibatanidzi nguva inodiwa kuti nanopositioning nhanho igare.

Zvese zviri zviviri zvinhu zvinokanganisa kurongeka uye kudzokorora uye zvinofanirwa kuverengerwa mune chero sisitimu yakatarwa.

5.Digital control

Kugadzirisa zvipingamupinyi zvekupindura kwema frequency, pamwe chete nekugadzirisa uye kusimuka nguva, zvinoenderana zvakanyanya nesarudzo chaiyo yekutonga system.Nhasi, aya madhijitari epamusoro zvakanyanya anobatana nechaiyo capacitive sensing masisitimu kuburitsa yakasarudzika kutonga kune sub-micron positional kurongeka uye yakakwirira velocities.

Semuenzaniso, yedu yazvino Queensgate yakavharwa-loop velocity controllers inoshandisa dijitari notch kusefa pamwe chete nekunyatso dhizaini dhizaini.Iyi nzira inovimbisa kuti resonant frequencies inoramba ichienderana kunyangwe pasi pekuchinja kwakakosha kwemutoro, uku ichipa kukurumidza kusimuka nguva uye pfupi nguva dzekugadzirisa - izvo zvese zvinowanikwa neakatanhamara mazinga ekudzokorora uye kuvimbika.

6.Beware specmanship!

Chekupedzisira, ziva kuti vagadziri vakasiyana vanowanzo sarudza kuunza masisitimu maitiro nenzira dzakasiyana, izvo zvinogona kuita kuti zviome kuenzanisa sekuda.Pamusoro pezvo, mune dzimwe nguva sisitimu inogona kuita zvakanaka kune mamwe maitiro - kazhinji ayo anosimudzirwa nemutengesi - asi anoshanda zvisina kunaka mune dzimwe nzvimbo.Kana iyo yekupedzisira isiri yakakosha kune yako chaiyo application, saka iyi haifanirwe kunge iri nyaya;zvisinei, zvinogoneka zvakaenzana kuti kana zvikafuratirwa zvinogona kuve nemhedzisiro inokuvadza pamhando yezvauchazogadzira kana tsvakurudzo zviitiko.

Kurudziro yedu nguva dzose kutaura nevakawanda vatengesi kuti uwane maonero akaenzana usati wafunga nezve nanopositioning system inonyatso kuzadzisa zvaunoda.Semugadziri anotungamira, anga achigadzira nekugadzira nanopositioning masisitimu - anosanganisira matanho, piezo actuators, capacitive sensors uye zvemagetsi isu tinogara tichifara kupa mazano uye ruzivo pane zvakasiyana nanopositioning technologies uye zvishandiso zviripo.
