Ukusombulula iingxaki zeempazamo ze-Linear Stage Wobble kunye ne-Pitch kwi-Multi-Axis Systems

Ngaba wakha waseka inkqubo entsha ye-multi-axis, efakwe kwikhamera yakho yokubona, waqala ulandelelwano lwakho lwentshukumo - waza wabukela umfanekiso uphuma kwingqwalasela ngaphandle kwesizathu esicacileyo? Okanye mhlawumbi ukhe wabona i-laser micromachining yakho itshintsha umgangatho kwindawo yokusebenza nangona umbane kunye noseto lwesantya zihlala zifana. Umonakalisi uhlala efihliwe: iimpazamo ezincinci ze-angular ezibizwa ngokuba yi-wobble kunye ne-pitch.

Ezi mpazamo zivakala ngathi zifihlakele. Azisoloko zibangela ii-alamu. Zitya kancinci kancinci umda wenkqubo yakho de iindawo ziqale ukungaphumeleli ekuhlolweni. Njengomvelisi weqonga lokuchaneka oneminyaka engaphezu kwesithoba esebenza kumzi-mveliso, sibone eli bali liqhubeka kwiiprojekthi ezininzi. Injongo yethu apha kukukubonisa indlela esebenza ngayo - kungekuko ngethiyori yeencwadi, kodwa ngokusombulula iingxaki ngendlela esebenzayo.

Kwaye siza kujongana nombuzo esiwubuzwa rhoqo:"Ndingayinciphisa njani ngempumelelo i-linear stage wobble kwaye ndisombulule iingxaki zepitch kwinkqubo yam ye-multi-axis linear stage?"Thabatha ikofu. Siza kuyicacisa le nto inyathelo ngenyathelo.

Zithini iimpazamo ze-Linear Stage Wobble kunye ne-Pitch, ngokwenene?

Masigcine iinkcazo zilula. Ukhwela iqonga ukuze uhambise umthwalo ukusuka ku-A ukuya ku-B kumgca othe tye. Kwihlabathi lokwenyani, inqwelo ayihambi nje ngokuthe tye. Ikwanyikima kancinci. Oko kunyikima kwahlulwahlulwa kube ziintshukumo ezintathu ezimbombo:

Intetho:iincam zenqwelo zinyuka okanye zihla njengesaw (ukujikeleza ujikeleze u-Y).

Yaw:inqwelo iqhuba ngasekhohlo okanye ngasekunene (ijikeleza u-Z).

Iroli:inqwelo ijikeleza umjikelo wohambo (ukujikeleza ujikeleze u-X).

Xa abantu bethethaukushukuma kwenqanaba elithe ngqo, badla ngokuchaza indibaniselwano yepitch kunye ne-yaw — intshukumo eyenza inxalenye yakho ivakale ngathi iyanqwala kwaye ijika endleleni yayo. Kwii-stacks ezininzi ze-multi-axis, i-pitch component yeyona ibuhlungu kakhulu kuba amandla adonsela phantsi kunye nemithwalo engenanto ihlala itsala phantsi kwinqwelo.

Cinga ngenaliti yokukhupha izinto ezincinci efakwe kwi-Z-axis. Ukuba inqanaba le-XY elingaphantsi line-ukushukuma kwenqanaba elithe ngqoKwi-microradians ezingama-40 kuphela, incam yenaliti ingahamba ngaphezulu kwe-4 microns ngokuthe nkqo kuhambo lonke. Oko kwanele ukuthambisa i-adhesive bead enobubanzi be-10 micron. Kwaye loo nto yi-axis enye kuphela. Xa ubeka ezimbini okanye ezintathu, iimpazamo ziyanda ngokukhawuleza.

Kutheni iiMulti-Axis Systems ziguqula iimpazamo ezincinci zibe ziingxaki ezinkulu

Isigaba se-single-axis sinokuba ne-pitch spec ye-20 arc-seconds. Oko kuyamangalisa kwiphepha ledatha. Kodwa kwi-ainqanaba lomgca we-axis ezininziistaki, izinto ziyaphazamiseka. Istaki esezantsi iyathambeka, kwaye loo tilt iba yindlela ecwangcisiweyo yestaki ebekwe phezulu. Ukuba istaki ephezulu inempazamo yayo yepitch, ufumana i-whammy ephindwe kabini. Siyibiza le mpazamo yestaki, kwaye yingakho inkqubo ye-2-axis idla ngokusebenza kakubi kunesixa seenkcukacha zayo zestaki nganye.

Kwi-stack ye-gantry-style multi-axis, impazamo ye-pitch evela kwi-axis esezantsi iba yi-offset ecwangcisiweyo kuyo yonke i-axis efakwe ngaphezulu kwayo.

Nantsi umzekelo wokwenyani osuka kumgangatho wethu wokuhlanganisa:
