Injini yaikulu yoyesera molondola: kugwiritsa ntchito ma micro stepper motors mu ma adapter amagetsi oyesera singano

Pankhani yopanga zamagetsi mwachangu komanso molondola kwambiri, ma adapter amagetsi oyesera singano amagwira ntchito ngati zipata zotsimikizira mtundu wa ma PCB, ma chips, ndi ma module. Pamene malo olumikizirana a zigawo akuchepa kwambiri ndipo zovuta zoyesera zikuchulukirachulukira, kufunikira kolondola ndi kudalirika pakuyesa kwafika pamlingo wapamwamba kwambiri. Mu kusinthaku kwa kuyeza kolondola, ma micro stepper motors amachita gawo lofunika kwambiri ngati "minofu yolondola". Nkhaniyi ifufuza momwe mphamvu yaying'ono iyi imagwirira ntchito molondola mu ma adapter amagetsi oyesera singano, zomwe zimapangitsa kuti kuyesa kwamakono kwamagetsi kukhale kosangalatsa.

一.Chiyambi: Pamene kulondola kwa mayeso kumafunika kuti pakhale pamlingo wa micron

Njira zoyesera zachikhalidwe zakhala zosakwanira pa zosowa za ma phukusi a BGA, QFP, ndi CSP amakono. Ntchito yayikulu ya adaputala yoyesera singano yamagetsi ndikuyendetsa ma probe ambiri kapena zikwizikwi kuti akhazikitse kulumikizana kodalirika kwa thupi ndi magetsi ndi malo oyesera pa chipangizo chomwe chikuyesedwa. Kusakhazikika kulikonse, kupanikizika kosagwirizana, kapena kukhudzana kosakhazikika kungayambitse kulephera kwa mayeso, kusaganizira bwino, kapena kuwonongeka kwa chinthu. Ma mota a micro stepper, omwe ali ndi kuwongolera kwawo kwapadera kwa digito komanso mawonekedwe olondola kwambiri, akhala njira yabwino yothetsera mavutowa.

一.Njira yogwirira ntchito ya micro stepper motor mu adaputala

Kugwira ntchito kwa mota ya micro stepper mu adaputala yoyesera singano yamagetsi si kungozungulira kosavuta, koma ndi mayendedwe olondola komanso oyendetsedwa bwino. Kayendedwe kake ka ntchito kakhoza kugawidwa m'magawo otsatirawa:

1. Kulinganiza bwino ndi malo oyamba

Kayendedwe ka ntchito:

Kulandira malangizo:Kompyuta yoyang'anira (yoyang'anira mayeso) imatumiza deta yolumikizana ya gawolo kuti liyesedwe ku khadi lowongolera mayendedwe, lomwe limasandutsa kukhala mndandanda wa zizindikiro za pulse.

Kuyenda kwa kusintha kwa kugunda kwa mtima:Zizindikiro za pulse izi zimatumizidwa kwa woyendetsa wa mota ya micro stepper. Chizindikiro chilichonse cha pulse chimayendetsa shaft ya mota kuti izungulire ngodya yokhazikika - "ngodya ya sitepe". Kudzera muukadaulo wapamwamba wa microstepping drive, ngodya yonse ya sitepe ingagawidwe m'ma microstep 256 kapena kuposerapo, motero kukwaniritsa kusuntha kwa micrometer-level kapena submicrometer-level.

Malo ogwirira ntchito:Injini, kudzera mu njira zotumizira monga zomangira zolondola kapena malamba oti nthawi igwire ntchito, imayendetsa ngolo yodzaza ndi ma probe oyesera kuti iyende pa ndege za X-axis ndi Y-axis. Dongosololi limasuntha molondola gulu la probe kupita pamalo omwe ali pamwamba pa mfundo kuti liyesedwe potumiza kuchuluka kwa ma pulse.

2. Kulamulira kupsinjika ndi kupanikizika

Kayendedwe ka ntchito:

Kuyerekeza kwa Z-axis:Pambuyo pomaliza kuyika malo a ndege, mota ya micro stepper yomwe imayang'anira kayendetsedwe ka Z-axis imayamba kugwira ntchito. Imalandira malangizo ndikuyendetsa mutu wonse woyesera kapena gawo limodzi la probe kuti lisunthe molunjika pansi motsatira Z-axis.

Kuwongolera kolondola kwa maulendo:Injini imakanikiza pansi bwino pang'onopang'ono, ndikulamulira bwino mtunda wa makina osindikizira. Izi ndizofunikira kwambiri, chifukwa mtunda waufupi kwambiri ungayambitse kukhudzana kosayenera, pomwe mtunda wautali kwambiri ungapangitse kuti kasupe wa probe ukhale wovuta kwambiri, zomwe zimapangitsa kuti pakhale kupanikizika kwakukulu komanso kuwonongeka kwa solder pad.

Kusunga Mphamvu Kuti Mupitirize Kupanikizika:Pamene chofufuziracho chafika pamlingo woyenerera wolumikizana ndi malo oyesera, mota ya micro stepper imasiya kuzungulira. Pa nthawiyi, mota, yokhala ndi mphamvu yake yogwira ntchito kwambiri, idzakhala yokhazikika pamalo ake, ndikusunga mphamvu yokhazikika komanso yodalirika popanda kufunikira kwa magetsi opitilira. Izi zimatsimikizira kukhazikika kwa kulumikizana kwamagetsi nthawi yonse yoyesera. Makamaka pa mayeso a chizindikiro cha pafupipafupi, kukhudzana kokhazikika kwa makina ndiye maziko a umphumphu wa chizindikiro.

3. Kusanthula kwa mfundo zambiri ndi kuyesa njira zovuta

Kayendedwe ka ntchito:

Pa ma PCB ovuta omwe amafunika kuyesedwa kwa zigawo m'malo osiyanasiyana kapena kutalika kosiyana, ma adapter amaphatikiza ma micro stepper motors angapo kuti apange dongosolo loyenda la multi-axis.

Dongosololi limayendetsa kayendetsedwe ka ma mota osiyanasiyana motsatira ndondomeko yoyesera yomwe yakonzedwa kale. Mwachitsanzo, poyamba limayesa Area A, kenako ma mota a XY amasuntha mogwirizana kuti asunthe probe array kupita ku Area B, ndipo mota ya Z-axis imakanikizanso pansi kuti iyesedwe. Njira iyi ya "flight test" imapangitsa kuti mayeso agwire bwino ntchito.

Mu ndondomeko yonseyi, mphamvu yokumbukira malo yeniyeni ya injini imatsimikizira kubwerezabwereza kwa kulondola kwa malo pa kayendedwe kalikonse, kuchotsa zolakwika zochulukirapo

一.Chifukwa chiyani muyenera kusankha ma micro stepper motors? - Ubwino wa makina ogwirira ntchito

Njira yogwirira ntchito yolondola yomwe yatchulidwa pamwambapa imachokera ku makhalidwe aukadaulo a mota ya micro stepper yokha:

Kusintha kwa digito ndi kulumikizana kwa pulse:Malo a injini amagwirizanitsidwa bwino ndi kuchuluka kwa ma pulse olowera, zomwe zimathandiza kuti pakhale kulumikizana bwino ndi makompyuta ndi ma PLC kuti azilamulira bwino digito. Ndi chisankho chabwino kwambiri poyesa zokha.

Palibe cholakwika chophatikizana:Pansi pa mikhalidwe yosadzaza kwambiri, cholakwika cha sitepe cha mota ya stepper sichimawonjezeka pang'onopang'ono. Kulondola kwa kayendetsedwe kalikonse kumadalira kokha magwiridwe antchito a mota ndi dalaivala, kuonetsetsa kudalirika kwa mayeso a nthawi yayitali.

Kapangidwe kakang'ono komanso kuchuluka kwa mphamvu yamagetsi:Kapangidwe kakang'ono kameneka kamalola kuti kalowe mosavuta mkati mwa zida zoyesera zazing'ono, pomwe kamapereka mphamvu yokwanira kuyendetsa gulu la probe, zomwe zimapangitsa kuti pakhale bwino pakati pa magwiridwe antchito ndi kukula kwake.

一.Kuthana ndi Mavuto: Ukadaulo Wothandizira Kugwira Ntchito Mwanzeru

Ngakhale kuti ndi zabwino zake, pakugwiritsa ntchito bwino, ma micro stepper motors amakumananso ndi zovuta monga resonance, vibration, ndi step loss zomwe zingachitike. Pofuna kuonetsetsa kuti ikugwira ntchito bwino mu electronic needle test adapters, makampaniwa agwiritsa ntchito njira zotsatirazi zokonzera zinthu:

Kugwiritsa ntchito mozama ukadaulo wa micro-stepping drive:Kupyolera mu micro-step, sikuti kokha mphamvu ya injini imawongoleredwa, komanso chofunika kwambiri, kuyenda kwa injini kumakonzedwa bwino, zomwe zimachepetsa kwambiri kugwedezeka ndi phokoso panthawi yoyenda pang'onopang'ono, zomwe zimapangitsa kuti kukhudzana kwa probe kukhale kogwirizana kwambiri.

Chiyambi cha dongosolo lolamulira lotsekedwa:Mu ntchito zina zomwe zimafunidwa kwambiri, ma encoder amawonjezedwa ku ma micro stepper motors kuti apange closed-loop control system. Dongosololi limayang'anira malo enieni a mota nthawi yeniyeni, ndipo likangopezeka kuti silikuyenda bwino (chifukwa cha kukana kwambiri kapena zifukwa zina), lidzakonza nthawi yomweyo, kuphatikiza kudalirika kwa open-loop control ndi chitsimikizo cha chitetezo cha closed-loop system.

一.Mapeto

Mwachidule, ntchito ya ma micro stepper motors mu ma adapter amagetsi oyesera singano ndi chitsanzo chabwino kwambiri chosinthira malangizo a digito kukhala mayendedwe olondola mdziko lapansi. Mwa kuchita zinthu zingapo zowongolera bwino, kuphatikizapo kulandira ma pulses, kupanga mayendedwe a micro-step, ndi kusunga malo, imagwira ntchito zofunika kwambiri monga kulumikizana molondola, kukanikiza kowongolera, ndi kusanthula kovuta. Sikuti ndi gawo lofunikira lokha lokwaniritsa zoyeserera zokha komanso injini yayikulu yolimbikitsira kulondola kwa mayeso, kudalirika, komanso kugwira ntchito bwino. Pamene zigawo zamagetsi zikupitilira kusintha kukhala zazing'ono komanso zolemera kwambiri, ukadaulo wa ma micro stepper motors, makamaka ukadaulo wake wowongolera micro-stepping ndi closed-loop, upitiliza kupititsa patsogolo ukadaulo woyesera zamagetsi kufika pamlingo watsopano.
