Emkhakheni wokukhiqiza nge-elekthronikhi ngesivinini esikhulu nangokunembile, ama-adaptha okuhlola inaliti kagesi asebenza njengabaqaphi abaqinisekisa ikhwalithi yama-PCB, ama-chips, namamojula. Njengoba isikhala sephini yezingxenye siba sincane kakhulu futhi ubunzima bokuhlola bukhula, izidingo zokunemba nokuthembeka ekuhlolweni zifinyelele emazingeni angakaze abonwe. Kulolu guquko lokulinganisa ngokunemba, ama-motor amancane adlala indima ebalulekile njenge "misipha eqondile". Lesi sihloko sizohlola ukuthi le ngxenye encane yamandla isebenza kanjani ngokunembile kuma-adaptha okuhlola inaliti kagesi, iqhube ukuhlolwa kwe-elekthronikhi kwesimanje enkathini entsha.
一.Isingeniso: Lapho ukunemba kokuhlola kudingeka kube sezingeni le-micron
Izindlela zokuhlola zendabuko azikaneli ngokwanele izidingo zokuhlola zamaphakheji anamuhla e-micro-pitch BGA, QFP, kanye ne-CSP. Umsebenzi oyinhloko we-adaptha yokuhlola inaliti kagesi ukushayela amashumi noma ngisho nezinkulungwane zama-probe okuhlola ukuze kusungulwe ukuxhumana okuthembekile ngokomzimba nakagesi namaphuzu okuhlola kuyunithi evivinywayo. Noma yikuphi ukungalungi okuncane, ingcindezi engalingani, noma ukuthintana okungazinzile kungaholela ekuhlulekeni kokuhlolwa, ukwahlulela kabi, noma ngisho nomonakalo womkhiqizo. Ama-motor ama-micro stepper, anokulawula kwawo kwedijithali okuhlukile kanye nezici zokunemba okuphezulu, abe yisisombululo esifanele sokubhekana nalezi zinselele.
一.Indlela yokusebenza eyinhloko yemoto encane ye-stepper ku-adaptha
Ukusebenza kwe-micro stepper motor ku-adapter yokuhlola inaliti kagesi akuyona into elula, kodwa uchungechunge lokunyakaza okuqondile nokulawulwayo okuhlelekile. Ukuhamba kwayo kungahlukaniswa ngezinyathelo ezilandelayo eziyinhloko:
1. Ukuqondanisa okunembile kanye nokubekwa kokuqala
Ukugeleza komsebenzi:
Ukuthola imiyalelo:Ikhompyutha ephethe (umphathi wokuhlola) ithumela idatha yokuxhumanisa yengxenye ezohlolwa ekhadini lokulawula ukunyakaza, eliyiguqula ibe uchungechunge lwezimpawu zokushaya kwenhliziyo.
Ukunyakaza kokuguqulwa kwe-pulse:Lezi zimpawu zokushaya kwenhliziyo zithunyelwa kumshayeli wemoto encane ye-stepper. Isignali ngayinye yokushaya kwenhliziyo ishayela umgodi wemoto ukuze ujikeleze i-engeli eqondile - "i-engeli yesinyathelo". Ngobuchwepheshe obuthuthukisiwe bokushayela nge-microstepping, i-engeli yesinyathelo ephelele ingahlukaniswa ibe yi-microsteps ezingu-256 noma ngaphezulu, ngaleyo ndlela kufezwe ukulawulwa kokufuduka kwezinga le-micrometer noma ngisho nezinga le-submicrometer.
Indawo yokusebenza:Injini, ngokusebenzisa izindlela zokudlulisa ezifana nezikulufo ze-lead eziqondile noma amabhande okulinganisa isikhathi, ishayela inqola egcwele ama-probe okuhlola ukuze ihambe ezindizeni ze-X-axis kanye ne-Y-axis. Uhlelo luhambisa ngokunembile i-probe array iye endaweni engenhla kwephuzu ukuze ihlolwe ngokuthumela inani elithile lama-pulse.
2. Ukulawulwa kokucindezelwa nokulawulwa kwengcindezi
Ukugeleza komsebenzi:
Ukulinganiselwa kwe-Z-axis:Ngemva kokuqeda ukubeka indiza, injini encane ye-stepper ephethe ukunyakaza kwe-Z-axis iqala ukusebenza. Ithola imiyalelo futhi iqhube lonke ikhanda lokuhlola noma imojuli eyodwa ye-probe ukuze ihambe ngokuqondile iye phansi nge-Z-axis.
Ukulawula okunembile kokuhamba:Injini icindezela phansi kahle ngezinyathelo ezincane, ilawula ngokunembile ibanga lokuhamba lomshini wokucindezela. Lokhu kubalulekile, njengoba ibanga elifushane kakhulu lokuhamba lingaholela ekuthinteni okubi, kanti ibanga elide kakhulu lokuhamba lingacindezela kakhulu isipilingi se-probe, okuholela ekucindezelekeni okukhulu kanye nomonakalo kuphedi yomshini wokucindezela.
Ukugcina I-Torque Ukuze Kuqhubeke Ingcindezi:Lapho i-probe ifinyelela ekujuleni kokuxhumana okusethwe ngaphambilini nephuzu lokuhlola, i-micro stepper motor iyayeka ukujikeleza. Kuleli phuzu, i-motor, ene-torque yayo yokubamba ephezulu, izokhiywa ngokuqinile endaweni yayo, igcine amandla okwehla ahlala njalo futhi athembekile ngaphandle kwesidingo sokunikezwa kwamandla okuqhubekayo. Lokhu kuqinisekisa ukuzinza kokuxhumeka kukagesi kulo lonke umjikelezo wokuhlola. Ikakhulukazi ekuhlolweni kwesignali yemvamisa ephezulu, ukuxhumana okuzinzile kwemishini kuyisisekelo sobuqotho besignali.
3. Ukuskena okunamaphuzu amaningi kanye nokuhlolwa kwendlela eyinkimbinkimbi
Ukugeleza komsebenzi:
Kuma-PCB ayinkimbinkimbi adinga ukuhlolwa kwezingxenye ezindaweni eziningi ezahlukene noma ezindaweni eziphakeme ezahlukene, ama-adapter ahlanganisa ama-motor amaningi amancane ukuze akhe uhlelo lokunyakaza olune-axis eminingi.
Uhlelo luhlela ukunyakaza kwama-motor ahlukahlukene ngokuya ngokulandelana kokuhlolwa okuhleliwe kusengaphambili. Isibonelo, kuqala luhlola i-Area A, bese ama-motor e-XY ehamba ngokuxhumana ukuze athuthe i-probe array aye ku-Area B, bese i-Z-axis motor icindezela phansi futhi ukuze ihlolwe. Le modi "yokuhlola indiza" ithuthukisa kakhulu ukusebenza kahle kokuhlola.
Kuyo yonke inqubo, ikhono lokukhumbula indawo eliqondile lenjini liqinisekisa ukuphindaphindeka kokunemba kokubeka endaweni ngayinye, kususwe amaphutha aqongelelekayo
一.Kungani ukhethe ama-motor amancane? - Izinzuzo ngemuva kwendlela yokusebenza
Indlela yokusebenza enembile eshiwo ngenhla ivela ezicini zobuchwepheshe zemoto ye-micro stepper uqobo:
Ukuvumelanisa kwedijithali kanye nokushaya kwenhliziyo:Indawo yemoto ihambisana kahle nenani lama-pulse okufaka, okuvumela ukuhlanganiswa okungenamthungo namakhompyutha nama-PLC ukuze kulawulwe ngokugcwele kwedijithali. Kuyisinqumo esifanele sokuhlola okuzenzakalelayo.
Akukho phutha elihlanganisiwe:Ngaphansi kwezimo zokungalayishi ngokweqile, iphutha lesinyathelo semoto ye-stepper aliqongelelani kancane kancane. Ukunemba kokunyakaza ngakunye kuncike kuphela ekusebenzeni okungokwemvelo kwemoto nomshayeli, okuqinisekisa ukuthembeka kokuhlolwa kwesikhathi eside.
Isakhiwo esincane kanye nobuningi be-torque ephezulu:Idizayini encane ivumela ukuthi ifakwe kalula ngaphakathi kwezinto zokuhlola ezihlanganisiwe, ngenkathi inikeza i-torque eyanele yokushayela i-probe array, okufeza ibhalansi ephelele phakathi kokusebenza nosayizi.
一.Ukubhekana Nezinselele: Ubuchwepheshe Bokuthuthukisa Ukusebenza Kahle Komsebenzi
Naphezu kwezinzuzo zayo ezivelele, ekusetshenzisweni okungokoqobo, ama-motor ama-micro stepper nawo abhekene nezinselele ezifana nokuzwakala, ukudlidliza, kanye nokulahlekelwa yizinyathelo okungenzeka. Ukuqinisekisa ukusebenza kwawo okungenaphutha kuma-adapter okuhlola inaliti kagesi, imboni isebenzise amasu okuthuthukisa alandelayo:
Ukusetshenziswa okujulile kobuchwepheshe be-micro-stepping drive:Ngokusebenzisa i-micro-stepping, akukhona nje kuphela ukuthi i-resolution iyathuthuka, kodwa okubaluleke kakhulu, ukunyakaza kwemoto kuyashelela, kunciphisa kakhulu ukudlidliza nomsindo ngesikhathi sokuhamba ngesivinini esiphansi, okwenza ukuthintana kwe-probe kuhambisane kakhudlwana.
Isingeniso sohlelo lokulawula oluvaliwe:Kwezinye izinhlelo zokusebenza ezifunwa kakhulu, ama-encoder ayengezwa kuma-micro stepper motors ukuze kwakheke uhlelo lokulawula oluyindilinga evaliwe. Uhlelo luqapha indawo yangempela yemoto ngesikhathi sangempela, futhi uma sekutholakale ukuthi ayisebenzi kahle (ngenxa yokumelana ngokweqile noma ezinye izizathu), izoyilungisa ngokushesha, ihlanganise ukuthembeka kokulawula okuvulekile kanye nesiqinisekiso sokuphepha sesistimu eyindilinga evaliwe.
一.Isiphetho
Ngamafuphi, ukusebenza kwama-motor ama-micro stepper kuma-adapter okuhlola inaliti kagesi kusebenza njengesibonelo esiphelele sokuguqula imiyalelo yedijithali ibe ukunyakaza okunembile emhlabeni ongokoqobo. Ngokwenza uchungechunge lwezenzo ezilawulwayo ngokunembile, okuhlanganisa ukwamukela ama-pulse, ukwenza ukunyakaza kwezinyathelo ezincane, nokugcina indawo, kufeza imisebenzi ebalulekile yokuqondanisa okunembile, ukucindezela okulawulwayo, kanye nokuskena okuyinkimbinkimbi. Akuyona nje ingxenye ebalulekile yokusebenza yokufeza ukuzenzekela kokuhlola kodwa futhi iyinjini eyinhloko yokuthuthukisa ukunemba kokuhlola, ukuthembeka, kanye nokusebenza kahle. Njengoba izingxenye ze-elekthronikhi ziqhubeka nokuthuthuka ziye ekuncipheni nasekuxineni okukhulu, ubuchwepheshe bama-motor ama-micro stepper, ikakhulukazi ubuchwepheshe bawo bokulawula i-micro-stepping kanye ne-closed-loop, buzoqhubeka nokuqhubekisela phambili ubuchwepheshe bokuhlola nge-elekthronikhi eziqongweni ezintsha.
