Injini huru yekuedza nemazvo: kushandiswa kwema micro stepper motors muma electronic needle test adapters

Mubasa rekugadzira ma electronic neanomhanya uye nemazvo, ma electronic needle test adapters anoshanda sevarindi vekuchengetedza mhando yema PCB, machipisi, uye ma modules. Sezvo nzvimbo ye pin component ichiva diki uye kuoma kwekuyedza kuchikwira, kudiwa kwekunyatsojeka uye kuvimbika mukuyedza kwasvika pakakwirira zvisati zvamboitika. Mukuchinja uku kwekuyera nemazvo, ma micro stepper motors anoita basa rinokosha se "tsandanyama dzakarurama". Chinyorwa chino chichaongorora kuti simba diki iri rinoshanda sei nemazvo muma electronic needle test adapters, zvichitungamira kuyedza kwemagetsi kwemazuva ano kunguva itsva.

一.Nhanganyaya: Kana kunyatsoongorora kunodiwa kuti kuve padanho re micron

Nzira dzekare dzekuyedza hadzina kukwana pakuedza zvinodiwa zvemapakeji eBGA, QFP, uye CSP anhasi. Basa guru re electronic needle test adapter nderekufambisa makumi kana kunyange zviuru zvema test probes kuti pave nekubatana kwakavimbika kwemuviri nemagetsi nenzvimbo dzekuyedza payuniti iri kuyedzwa. Chero kusarongeka kudiki, kumanikidzwa kusina kuenzana, kana kusangana kusina kugadzikana kunogona kutungamira mukukundikana kwekuyedza, kusatonga zvakanaka, kana kutokuvadzwa kwechigadzirwa. Micro stepper motors, ine kutonga kwavo kwedhijitari kwakasiyana uye hunhu hwayo hwakarurama, yave mhinduro yakanaka yekugadzirisa matambudziko aya.

一.Maitiro ekushanda kwemota ye micro stepper mu adapta

Kushanda kwemota ye micro stepper mu electronic needle test adapter hakusi kungotenderera kuri nyore, asi kufamba kwakarongeka uye kwakanyatsorongeka. Kufamba kwayo kunogona kupatsanurwa kuita matanho makuru anotevera:

1. Kurongeka kwakarurama uye nzvimbo yekutanga

Mafambiro ebasa:

Kugamuchira mirairo:Kombiyuta inotambira (test host) inotumira data rechikamu chinoongororwa kuti chiongororwe kukadhi rekudzora kufamba, iro rinochishandura kuita nhevedzano yezviratidzo zvekurova kwemoyo.

Kufamba kwekushandura kwepulse:Masaini aya epulse anotumirwa kumutyairi wemota ye micro stepper. Chiratidzo chega chega chepulse chinotyaira mota kuti itenderedze kona yakatarwa - "step angle". Kuburikidza netekinoroji yepamusoro ye microstepping drive, kona yakazara yenhanho inogona kukamurwa kuita 256 kana kupfuura microsteps, nokudaro ichikwanisa kudzora displacement control ye micrometer-level kana submicrometer-level.

Nzvimbo yekushanda:Mota iyi, kuburikidza nemidziyo yekufambisa yakaita semasikuruu ekutungamira akarurama kana mabhandi enguva, inotyaira ngoro yakazadzwa nemaprobe ekuyedza kuti ifambe paX-axis neY-axis planes. Sisitimu iyi inofambisa probe array kuenda panzvimbo iri pamusoro penzvimbo kuti iongororwe nekutumira nhamba chaiyo yemapulses.

2. Kudzora kudzvinyirirwa uye manejimendi ekumanikidzwa

Mafambiro ebasa:

Kufungidzirwa kweZ-axis:Mushure mekupedza kuisa plane positioning, micro stepper motor ine chekuita nekufamba kweZ-axis inotanga kushanda. Inogamuchira mirairo uye inotyaira musoro wese wekuyedza kana module imwe chete yeprobe kuti ifambe yakatwasuka ichitevedza Z-axis.

Kudzora kufamba kwakarurama:Mota inodzvanya zvinyoro nyoro pasi nematanho madiki, ichinyatso dzora daro rekufamba kwemuchina wekudzvanya. Izvi zvakakosha, sezvo daro diki rekufamba rinogona kukonzera kusabatana zvakanaka, nepo daro diki rekufamba rinogona kudzvanya chitubu cheprobe zvakanyanya, zvichikonzera kumanikidzwa kwakanyanya uye kukuvara kwepadhi rekusolder.

Kuchengetedza Torque Kuti Urambe Uchimanikidzwa:Kana probe yasvika padanho rekuonana nechinhu chinoyedzwa, mota ye micro stepper inomira kutenderera. Panguva iyi, mota, ine simba rayo rekubata rakasimba, inenge yakavharwa zvakanaka, ichichengetedza simba rakasimba uye rakavimbika pasina chikonzero chemagetsi anoramba achienderera mberi. Izvi zvinoita kuti kubatana kwemagetsi kugadzikane mukati menguva yese yekuedza. Kunyanya pakuongorora zviratidzo zvine frequency yakakwira, kubatana kwemechanical kwakasimba ndiyo hwaro hwekuvimbika kwechiratidzo.

3. Kuongororwa kwenzvimbo dzakawanda uye kuyedzwa kwenzira kwakaoma

Mafambiro ebasa:

Kune maPCB akaomarara anoda kuyedzwa kwezvikamu munzvimbo dzakasiyana-siyana kana pakukwirira kwakasiyana, maadapter anobatanidza mamota akawanda e micro stepper kuti aumbe sisitimu yekufamba ine axis dzakawanda.

Sisitimu iyi inotungamira kufamba kwemamota akasiyana zvichienderana nehurongwa hwekuedza hwakarongwa kare. Semuenzaniso, inotanga yaedza Area A, yozoti mamota eXY anofamba pamwe chete kuti atamise probe array kuenda kuArea B, uye mota yeZ-axis inodzvanya zvakare kuti iongororwe. Iyi "flight test" mode inovandudza zvikuru kushanda kwekuyedza.

Mukati mese maitiro ese, kugona kwekurangarira nzvimbo chaiyo yemota kunoita kuti kudzokororwa kwekururama kwenzvimbo yacho pakufamba kwega kwega, zvichibvisa zvikanganiso zvakaunganidzwa.

一.Sei uchifanira kusarudza mota dze micro stepper? - Mabhenefiti ari shure kwekushanda kwemuchina

Maitiro ekushanda ataurwa pamusoro apa anobva pane hunhu hwehunyanzvi hwemota ye micro stepper pachayo:

Kubatanidza kwedhijitari uye Kubatana kwePulse:Nzvimbo yemota yakanyatsoenderana nehuwandu hwemapuls ekupinda, zvichiita kuti isanganisirwe zvakanaka nemakomputa nemaPLC kuti ikwanise kudzora zvizere. Ndiyo sarudzo yakakodzera yekuyedza otomatiki.

Hapana kukanganisa kwakaunganidzwa:Kana mota ye stepper isingaremerwe zvakanyanya, kukanganisa kwe stepper hakuunganidzwi zvishoma nezvishoma. Kururama kwekufamba kwega kwega kunoenderana chete nekushanda kwemota nemutyairi, zvichiita kuti ive yakavimbika pakuyedzwa kwenguva refu.

Chimiro chakabatana uye huwandu hwakawanda hwe torque:Dhizaini diki iyi inoita kuti ikwanise kuiswa zviri nyore mukati mezvishandiso zvekuedza zvishoma, ukuwo ichipa torque yakakwana yekufambisa probe array, zvichiita kuti pave nekuenzana kwakakwana pakati pekushanda nehukuru.

一.Kugadzirisa Matambudziko: Tekinoroji Yekuvandudza Kushanda Nesimba Kwebasa

Pasinei nezvakanakira zvayo, mumashandisirwo azvo chaiwo, ma micro stepper motors anosanganawo nematambudziko akadai se resonance, vibration, uye step loss inogona kuitika. Kuti ive nechokwadi chekuti inoshanda zvakanaka muma electronic needle test adapters, indasitiri iyi yakashandisa nzira dzinotevera dzekugadzirisa:

Kushandiswa kwakadzama kwetekinoroji ye micro-stepping drive:Kuburikidza ne micro-stepping, resolution haisi kungovandudzwa chete, asi chinonyanya kukosha ndechekuti kufamba kwemota kunogadziriswa, zvichideredza zvakanyanya kudedera uye ruzha panguva yekukambaira zvishoma, zvichiita kuti kubata kweprobe kuve kwakanyatsoenderana.

Sumo yehurongwa hwekudzora hwakavharwa:Mune mamwe mashandisirwo anonyanya kudiwa, ma encoders anowedzerwa kuma micro stepper motors kuti agadzire closed-loop control system. Sisitimu iyi inotarisa nzvimbo chaiyo yemota panguva chaiyo, uye kana yangoonekwa kuti haina kushanda zvakanaka (nekuda kwekusakwanisa kushanda zvakanyanya kana zvimwe zvikonzero), inoigadzirisa nekukasika, ichibatanidza kuvimbika kwe open-loop control nevimbiso yekuchengetedza ye closed-loop system.

一.Mhedziso

Muchidimbu, mashandiro ema micro stepper motors muma electronic needle test adapters anoshanda semuenzaniso wakakwana wekushandura mirairo yedhijitari kuita mafambiro chaiwo munyika yepanyama. Nekuita zviito zvakatevedzana zvinodzorwa zvakanyatsonaka, zvinosanganisira kugamuchira ma pulses, kuita mafambiro e micro-step, uye kuchengetedza nzvimbo, inoita mabasa akakosha ekurongeka kwakanyatsonaka, kudzvanya kunodzorwa, uye kuskena kwakaoma. Haisi chete chinhu chakakosha chekuita kuti bvunzo dziite otomatiki asiwo injini huru yekuvandudza kururama kwekuyedza, kuvimbika, uye kushanda zvakanaka. Sezvo zvikamu zvemagetsi zvichiramba zvichichinja kuenda ku miniaturization uye high density, tekinoroji yema micro stepper motors, kunyanya tekinoroji yayo ye micro-stepping uye closed-loop control, icharamba ichisimudzira tekinoroji ye electronic testing kusvika pakakwirira.
