Ukuxazulula Amaphutha Okuwohloka Kwesiteji Esiqondile kanye Nokugoba Ezinhlelweni Eziningi Ezihambisana Ne-Axis

Wake wasungula uhlelo olusha lwe-multi-axis, olufakwe kukhamera yakho yokubona, waqala ukulandelana kwakho kokunyakaza — futhi wabuka isithombe siphuma ekugxileni ngaphandle kwesizathu esibonakalayo? Noma mhlawumbe uke wabona ukushintsha kwekhwalithi ye-laser micromachining yakho endaweni yokusebenza yize izilungiselelo zamandla nesivinini zihlala zinjalo. Isici sivame ukucasha endaweni esobala: amaphutha amancane e-angular abizwa ngokuthi i-wobble and pitch.

Lawa maphutha azwakala eyimfihlo. Azihlali zibangela ama-alamu. Adla kancane kancane i-margin yenqubo yakho kuze kube yilapho izingxenye ziqala ukwehluleka ukuhlolwa. Njengomkhiqizi wesiteji sokunembile oneminyaka engaphezu kweyisishiyagalolunye esebenza efektri, sibone le ndaba iqhubeka phakathi kwamaphrojekthi amaningi. Umgomo wethu lapha ukukuqondisa kuyo - hhayi ngethiyori yezincwadi, kodwa ngokuxazulula izinkinga ezisebenzayo, eziqala phansi.

Futhi sizophendula umbuzo esivame ukuwubuzwa:"Ngingakunciphisa kanjani ngempumelelo ukuntengantenga kwesigaba esiqondile futhi ngixazulule amaphutha ephimbo ohlelweni lwami lwesigaba esiqondile esinama-axis amaningi?"Thatha ikhofi. Sizoyichaza kahle le ndaba.

Ayini Amaphutha Okuwohloka Kwesiteji Esiqondile kanye Nokugoba, Ngempela?

Masigcine izincazelo zilula. Ugibela isiteji ukuze uhambise umthwalo kusuka ku-A uye ku-B ngendlela eqondile. Ezweni langempela, inqola ayihambi nje iqonde. Iphinde inyakaze kancane. Lokho kuzamazama kuhlukana kube ukunyakaza okuthathu okune-angle:

Iphimbo:inqola ibheke phezulu noma phansi njenge-seesaw (ukujikeleza kuzungeze u-Y).

Yaw:inqola iqondisa kwesobunxele noma kwesokudla (ijikeleza u-Z).

Ukugoqa:inqola ijikeleza i-axis yokuhamba (ukujikeleza kuzungeze u-X).

Uma abantu bekhulumaukuxega kwesigaba esiqondile, bavame ukuchaza inhlanganisela yephimbo kanye nokubhonga — ukunyakaza okwenza ingxenye yakho izwakale sengathi iyanqekuzisa ikhanda futhi iyasonta endleleni yayo. Ezinqwabeni eziningi ze-multi-axis, ingxenye yephimbo ilimaza kakhulu ngoba amandla adonsela phansi kanye nemithwalo egobile ihlala idonsela phansi enqoleni.

Cabanga ngenaliti yokukhipha i-microdispensing efakwe ku-Z-axis. Uma isigaba se-XY esingaphansi sine-ukuxega kwesigaba esiqondilekuma-microradians angu-40 kuphela, isihloko senalithi singahamba ngaphezu kwama-micron angu-4 siqonde phakathi kohambo. Lokho kwanele ukugcoba ubuhlalu obunamathelayo obuyi-micron engu-10 ububanzi. Futhi lokho kuyi-axis eyodwa nje. Uma ubeka amabili noma amathathu, amaphutha ayanda ngokushesha.

Kungani Izinhlelo Ezine-Axis Eziningi Ziguqula Amaphutha Amancane Abe Izinkinga Ezinkulu

Isigaba se-single-axis singase sibe ne-pitch spec yemizuzwana engu-20 ye-arc. Lokho kuyamangalisa eshadini ledatha. Kodwa ku-isigaba esiqondile se-axis eminingii-stack, izinto ziyaphazamiseka. Isigaba esingezansi siyathambekela, futhi lokho kuthambekela kuba yindlela ehlelekile yesigaba esibekwe phezulu. Uma isigaba esiphezulu sinephutha laso lokuphonsa, uthola iphutha eliphindwe kabili. Lokhu sikubiza ngokuthi iphutha lokufaka i-stacking, futhi yingakho uhlelo olune-axis ezimbili luvame ukwenza kabi kakhulu kunesamba semininingwane yalo yesigaba ngasinye.

Esitokisini se-multi-axis sesitayela se-gantry, iphutha le-pitch elivela ku-axis engezansi liba yi-offset ehlelekile ye-axis ngayinye efakwe ngaphezu kwayo.

Nasi isibonelo sangempela esivela endaweni yethu yokuhlanganisa:

Ungabona ukuthi izinombolo azihlanganisi nje kuphela — zihlanganiswa nezingalo zomthwalo kanye nezesikhashana. Yingakho njeukuxazulula inkinga yephutha lokuphakamisaphakathi kuisigaba esiqondile se-axis eminingikumele ngibheke yonke inqwaba, hhayi nje izimbazo ngazinye.

Izigaba eziqondile ze-cross-roller vs. ezithwala ibhola ukuze kuqhume futhi kusebenze kahle i-pitch

Noma ubani owakha uhlelo lokunemba uzobhekana nombuzo obalulekile wokukhetha. Luyinto yakudalaIzigaba eziqondile ze-cross-roller vs. ezithwala ibhola ukuze kuqhume futhi kusebenze kahle i-pitchImpikiswano. Ayikho impendulo eyodwa efanela konke. Ake siyichaze ngokusekelwe kulokho esikulinganisile ezibhentshini zethu zokuhlanganisa eminyakeni engu-9 edlule.

Izigaba ezigoqekayosebenzisa ama-roller asilinda ku-V-groove. Afinyelela ukuxhumana komugqa, okusho ukuqina okuphezulu kanye namaphutha aphansi e-angular ngokwemvelo.Iziqondiso eziqondile eziphethe ibholasebenzisa amabhola ajikelezayo athintana nendawo. Ashesha, aphatha ukuhamba isikhathi eside kalula, kodwa anokuqina okuphansi kancane kwe-engela.

Isiteji Esihamba Ngezingqimba Ezinqamulayo	Umhlahlandlela Wokuthwala Amabhola

Ukuze wenze lokhu kukhonkolo, nansi ukuqhathanisa okusekelwe ezigabeni ezijwayelekile zohlu lwethu lomkhiqizo (ukuhamba okungu-100 mm, ububanzi bomzimba obungu-60 mm):

Uma inqubo yakho idinga ukuqina okukhulu ngangokunokwenzekaukuxega kwesigaba esiqondileukulawula — ake sithi ekuqondisweni kwe-optical noma ekuhlolweni — i-cross-roller iyintandokazi esindayo. Sivame ukuqondisa abantu be-semiconductor kuma-cross-rollerisigaba esiqondile se-axis eminingiizitaki ngenxa yaleso sizathu. Kodwa uma udinga ukumboza isigamu semitha yokuhamba ngesivinini esikhulu ngomthwalo osindayo ongu-15 kg futhi ukwazi ukukala nokulungisa amaphutha e-angular kusofthiwe, isigaba sokuthwala ibhola ngokunemba sinengqondo ephelele.

Isihluthulelo ukufanisa ubuchwepheshe nesabelomali samaphutha angempela, hhayi nje ukuphishekela izici eziphansi kakhulu ephepheni.

Ukulungiswa Kwangempela Kwezinhlelo Zokusebenza Ezinthathu Eziyinhloko

Ake sikwenze lokhu. Nansi indlelaukuxega kwesigaba esiqondilefuthi amaphutha okulinganisa avela — futhi axazululwe — ezinkambeni ezintathu ezidinga usizo.

Ukuhlolwa kwe-Wafer ye-Semiconductor

Ku-Ukuhlolwa kwe-wafer ye-semiconductor, aisigaba esiqondile se-axis eminingii-rasters i-wafer ngaphansi kwenhloso ye-microscope. Ukujula kokugxila kungaba ngaphansi kwe-micron eyi-1. Uma i-stack yesiteji ine-pitch engama-arc-seconds angu-30, ubuso be-wafer bushintsha ngama-microns amaningana ngesikhathi sokuskena. Lokho kukunikeza izithombe ezifiphele kanye namaphutha angatholakali.

Onjiniyela bethu bavame ukuhlasela le nkinga ngokuqinisa i-orthogonality, banciphise i-Abbe offset (ukubeka i-objective ngakwesokudla phezu kwenqola ehambayo), bese bekhetha izigaba ze-cross-roller ezine-pitch elinganisiwe ngaphansi kwemizuzwana engu-15 ye-arc. Siphinde sincome umjikelezo wokufudumala ukuze kuqiniswe i-thermal warping ngaphambi kokuhlolwa. Ikhasimende elilodwa linciphisa amaphutha alo okususa ukugxila ngo-40% ngokulungisa nje i-mounting base flatness.

I-Laser Micromachining

Ku-i-laser micromachining, i-engeli yogongolo ibalulekile. Uma isiteji siphakama ngesikhathi sokusika, i-kerf iyanwebeka futhi imiphetho iyancipha. Sisebenze nomenzi wedivayisi yezokwelapha owayesusa ama-stents ngenxa yekhwalithi yokusika engaguquki endaweni yokusebenza.

Umshini wokusika nge-laser wezimboni onezinsika zokuqondisa eziqondile eziveziwe — iphutha lephimbo ezinsikeni ze-gantry lihumusha ngokuqondile ezinqeni ezinciphile kanye nokujula kokusika okungaguquki kuyo yonke imvilophu yomsebenzi.
