Linear Stepper Actuator

Linear stepper actuator he mea wehe -loop control linear drive device e hoʻopili pololei i ka stepper motor me ka linear transmission machine, a loaʻa i ka neʻe ʻokoʻa ma o ka hoʻomalu ʻana i ka hōʻailona pulse. ʻO ka linear stepper actuator kahi mea electromechanical e hoʻohuli i nā hōʻailona pulse uila i ka neʻe laina laina pololei, e hui pū ana i nā hiʻohiʻona hoʻokele pulse o kahi kaʻa stepper me ka hiki ke hoʻopuka i ka neʻe laina. Hoʻohana nui ʻia ia i nā hiʻohiʻona e koi ana i ke kūlana pololei akā ʻaʻole koi i ka mana kiʻekiʻe i pani ʻia.

ʻO nā hiʻohiʻona nui o Linear stepper actuator he ʻano maʻalahi, haʻahaʻa haʻahaʻa, a me ke kūlana me ka ʻole o ka pane ʻana, kūpono no nā hiʻohiʻona automation me ka haʻahaʻa haʻahaʻa haʻahaʻa a haʻahaʻa haʻahaʻa haʻahaʻa, e like me ka paʻi 3D, nā lāʻau lapaʻau, automated packaging, etc.

ʻO kakumu hanaoHoʻokumu ʻia ka mea hana stepper linear ma ka ʻanuʻu -ma-ʻano hoʻololi ʻanuʻu o nā ʻenekini stepper:

Hoʻouna ka mea hoʻoponopono i nā hōʻailona pulse e hoʻokele i ke kaʻa stepper e hoʻohuli i kēlā me kēia ʻanuʻu ma kahi kihi paʻa (e like me 1.8 degere / ʻanuʻu), a laila hoʻohuli i ka neʻe ʻana i ka neʻe laina ma o nā mīkini hoʻoili e like me nā ʻūlū a me nā mea hana. No kēlā me kēia puʻupuʻu hoʻokomo, hoʻoneʻe ka mea hana i kahi mamao paʻa (maʻamau i nā micrometers), a ua kūlike ka neʻe ʻana i ka helu o nā pulses. Hiki iā ia ke hoʻokō i ka mana kikoo -loop me ka ʻole o nā mea ʻike manaʻo a he ʻano maʻalahi kona.

Ma ke ʻano, ʻo ka linear stepper actuator ka mea nui i ʻekolu ʻāpana:

he mea hoʻokele kaʻa (ke kaʻa stepper a me ke kaʻa kaʻa kaʻa), he ʻāpana hoʻoili (ka pōlele a i ʻole trapezoidal screw, kuleana no ka hoʻololi ʻana i ka ʻōwili i loko o ka neʻe laina), a me kahi ʻōnaehana alakaʻi (nā laina laina a i ʻole nā ​​ala alakaʻi, e hōʻoia ana i ka holo mālie). Hoʻohui kekahi mau hiʻohiʻona i nā hoʻololi palena e pale i ka hana overtravel a maʻalahi i ka hoʻolālā ʻōnaehana.

Hoʻopili ʻia ka noi i nā hiʻohiʻona haʻahaʻa haʻahaʻa i ka pololei pololei:

Nozzle feed no nā mea paʻi 3D, ka pahu hana no nā mea mīkini CNC liʻiliʻi, ka hoʻololi ʻana i nā laʻana no nā lako hana ʻenehana, ka hoʻomalu ʻana i ka nui o nā mea lapaʻau (e like me ka infusion pumps), ka nānā ʻana o nā lens no nā lako palekana, a pēlā aku. He kūpono ka mea hana stepper linear no nā hiʻohiʻona neʻe intermittent me nā haʻahaʻa māmā a me ka hoʻihoʻi kiʻekiʻe. Hiki ke pi'i ma'amau ka pololei o ka 'anu'u i ka ± 0.01mm, e kūpono ana i nā pono o ka nui o nā mea hana automate li'ili'i a me waena.

Ma ʻaneʻi mākou e hōʻike aku iā ʻoe i ke ala alakaʻi i kūkulu ʻia-ma Linear Module, TMTH8 penei:

Hoʻokipa ʻia ʻoe e nānā i nā papahana hou aʻe a e kipa i kā mākou hale kiʻi wikiō e Youtube: https://www.youtube.com/@tallmanrobotics

Aia nā ʻokoʻa koʻikoʻi ma waena o ka linear stepper motor actuators a me linear servo motor actuators e pili ana i nā ʻano kaohi, nā hiʻohiʻona hana, a me nā hiʻohiʻona pili. ʻO nā ʻokoʻa kikoʻī penei:

1. Nā loina mana like ʻole

Linear stepper motor actuator: hoʻohana i ka mana loop open{0}}, hoʻohuli i ke kaʻa e hoʻololi (a neʻe paha ma kahi laina pololei) ma kahi mamao ʻanuʻu paʻa ma ka loaʻa ʻana o nā hōʻailona puʻupuʻu, a pili pono ka neʻe ʻana i ka helu o nā pulupulu, me ka ʻole o ka pono o nā ʻike manaʻo kūlana. I ka lōʻihi o ka pololei o ka hōʻailona pulse, hiki ke hoʻokō ʻia ka neʻe i hoʻonohonoho mua ʻia, akā ʻaʻole hiki ke ʻike inā haʻalele ke kūlana maoli mai ke aʻo ʻana.

Linear servo motor actuator: hoʻohana i ka -loop control paʻa, hoʻohui i nā mea ʻike kūlana (e like me ka grating ruler, encoder), a hoʻihoʻi i ke kūlana maoli a me ka wikiwiki i ka mea hoʻoponopono i ka manawa maoli. Hoʻohālikelike ka mea hoʻoponopono i ka waiwai kauoha me ka waiwai manaʻo, hoʻoponopono ikaika i ka hopena e hōʻoia i ka pololei o ka neʻe ʻana, a hiki ke hoʻoponopono i nā ʻokoʻa i hoʻololi ʻia e ka hoʻololi ʻana a me nā hewa mechanical.

2. ʻOkoʻa ka pololei a me ka hana hewa

Linear stepper motor actuator: pili ka pololei i ke kūlike o ka ʻanuʻu ʻanuʻu (a i ʻole linear step), me ka hiki ʻole ke hoʻoponopono hewa. Inā ʻoi aku ka nui o ka haʻawe a ʻoi aku ka kiʻekiʻe o ka puʻuwai puʻuwai, hiki ke nalowale ka pae (ʻoi aku ka liʻiliʻi o ka neʻe ʻana ma mua o ka neʻe ʻana i kauoha ʻia), a e hōʻiliʻili nā hewa. ʻO ka pololei o ka ʻanuʻu ka mea maʻamau ± 0.01mm 0.1mm.

Linear servo motor actuator: Hoʻoponopono hewa manawa maoli ma o ka -loop manaʻo, ikaika anti-hiki keakea, ʻoi aku ka pololei o ka hoʻihoʻi hou ʻana (a hiki i ± 0.001mm 0.01mm), ʻoiai inā loaʻa ka ukana a i ʻole ke keakea o waho, hiki ke hoʻihoʻi ʻia i ke kūlana i kauoha ʻia ma o ka hoʻoponopono ʻole ʻana.

3. ʻOkoʻa ka wikiwiki a me ka pane ikaika

Linear stepper motor actuator: paʻa haʻahaʻa haʻahaʻa -wikiwiki hana, akā hiki i ka haʻalulu a me ke kapuaʻi nalo i ka wā kiʻekiʻe{1}}wikiwiki hana, a me ka pukana torque emi me ka piʻi ʻana o ka māmā (aia ka pilikia o ka "step loss"), kūpono no ka haʻahaʻa -wikiwiki a me ka manawa.

Linear servo motor actuator: Me ka wikiwiki kiʻekiʻe kiʻekiʻe kiʻekiʻe -wikiwiki pane a pani ʻia-ka hoʻomalu, hiki iā ia ke mālama i ka puka paʻa ma luna o kahi ākea ākea. ʻOi aku ka maʻalahi o nā kaʻina hana wikiwiki a me ka hoʻohaʻahaʻa ʻana, kūpono ia no nā hiʻohiʻona e koi ana i ka hoʻomaka wikiwiki a i ʻole ka neʻe ʻana o ka wikiwiki kiʻekiʻe.

4. ʻOkoʻa haawe hiki a me torque hiʻona

Linear stepper motor actuator: Ke emi iho nei ka torque pukana (a i ʻole ke kuʻi) me ka hoʻonui wikiwiki. Ma nā haʻahaʻa haʻahaʻa, ʻoi aku ka nui o ka torque, akā i nā wikiwiki kiʻekiʻe, hiki ke hoʻonui i ka ukana ma lalo o nā ukana kaumaha. He kūpono ia no nā haʻahaʻa māmā (maʻamau ma lalo o 500N) a me nā hiʻohiʻona haʻahaʻa inertia.

Linear servo motor actuator: Ma o ka -loop control paʻa, hiki ke hoʻololi i ka mana hoʻopuka e like me nā loli hoʻouka. Ua ʻoi aku ka ikaika o ka māmā kiʻekiʻe a me ke kaumaha{3}}ʻoihana, a hiki iā ia ke mālama i ka pahu paʻa i nā māmā kiʻekiʻe. He kūpono ia no nā hiʻohiʻona me nā haʻahaʻa haʻahaʻa a kiʻekiʻe (a hiki i nā tausani o nā newtons) a me ka inertia kiʻekiʻe.

5. Nā kumukūʻai like ʻole a me nā paʻakikī

Linear stepper motor actuator: hana maʻalahi, ʻaʻohe pono no nā mea ʻike manaʻo, kaapuni hoʻomalu maʻalahi, kumu kūʻai haʻahaʻa (maʻamau 1/3 ~ 1/2 o ka ʻōnaehana servo), paʻakikī haʻahaʻa haʻahaʻa, kūpono no nā mea liʻiliʻi a me waena -me ka palena kālā.

Linear servo motor actuator: koi i ka hoʻohui ʻana o nā mea ʻike a me nā algorithms control loop -paʻi paʻakikī, he kumu kūʻai, a ʻoi aku ka paʻakikī o ka hoʻoponopono hoʻoponopono (e like me ka hoʻoponopono ʻana i nā parameter), no laila kūpono ia i nā mea hana pololei me nā koi hana kiʻekiʻe.

6. Nā hiʻohiʻona pili like ʻole

Linear stepper motor actuator: kūpono no ka haʻahaʻa haʻahaʻa, haʻahaʻa māmā, haʻahaʻa -wikiwiki neʻe hou i nā hiʻohiʻona, e like me 3D mīkini paʻi nozzle hānai, mea liʻiliʻi lawe lawe, keʻena hoʻokolohua pae kūlana kūlana, home appliance valve control, etc.

Linear servo motor actuator: kūpono no ke kiʻekiʻe -pololei, haawe kiʻekiʻe, kiʻekiʻe-wikiwiki pane dynamic, e like me ka semiconductor wafer lawelawe, laser oki kūlana, precision assembly robots, lāʻau lapaʻau lako, etc.

Hōʻuluʻulu a me ka Papa Hoʻohālikelike

I ke koho 'ana, pono e ho'oholo i ka ho'oholo 'ana ma muli o nā koi o ka noi no ka pololei, ka wikiwiki, ka ukana, a me ke kumu kū'ai kālā: no nā hi'ohi'ona māmā a ma'alahi, 'oi aku ka maika'i o ka he'e 'ana, a no nā hi'ohi'ona ki'eki'e a me nā hi'ohi'ona ki'eki'e, koi 'ia ka servo.
