Isakhiwo Semishini Serobhothi Elisebenzisa Injection Molding Robot Elinama-Axis Amahlanu

Ukwakheka Kwemishini Komjovo We-Five-Axis Irobhothi Lokubumba: Ukuhlaziywa Okuyinhloko Kokusebenza Okuqondile Nokubambisana Okusebenzayo

Ekwenzeni ngokuzenzakalelayo kokubumba ngomjovo wesimanje, amarobhothi okubumba umjovo we-axis emihlanu, ngamakhono abo okusebenza aguquguqukayo, anezinhlangothi eziningi, abe yimishini ebalulekile yokuthuthukisa ukusebenza kahle kokukhiqiza nokunciphisa izindleko zabasebenzi. Ukusebenza kwabo okuvelele kuqhutshwa uhlelo lwemishini oluklanywe ngokucophelela—kusukela kuyunithi yokushayela kuya ku-effector yokugcina—lapho ukusebenza okuhlanganisiwe kwengxenye ngayinye kunquma ukusebenza kwerobhothi ekubambeni ngesivinini esikhulu, ukubeka indawo enembile, kanye nokunyakaza okuyinkimbinkimbi kwendlela. Lesi sihloko sizohlinzeka ngokuhlaziywa okujulile kwesakhiwo semishini esiyinhloko serobhothi lokubumba umjovo elinama-axis amahlanu, okwembula ukuxhumana okukhona phakathi kokusebenza kwemishini nokwakheka kwesakhiwo, kusiza izinkampani ukuthi zenze izinqumo zokukhetha imishini ezinembe kakhudlwana ngesikhathi sokuthuthukiswa kokuzenzakalela.

Ukwakhiwa Okuyisisekelo: "Uhlaka Lwamathambo" Lohlelo Lokunyakaza Lwe-Five-Axis

Isakhiwo somshini serobhothi lokubumba elinomjovo onama-axis amahlanu sisekelwe ohlelweni lokuxhumanisa olunama-multi-joint. Ngokuhlanganisa ama-axes amathathu aqondile (X, Y, kanye no-Z) nama-axes amabili ajikelezayo (A kanye no-B), kufinyelela uhla oluphelele lokunyakaza ngezinga ezintathu. Lo mklamo udlula imikhawulo yokunyakaza yendabuko emithathu-Amarobhothi e-Axis, okubonisa izinzuzo ezibalulekile ekuphatheni izingxenye ezibunjiwe ngendlela engavamile kanye nokususa izingxenye ezibunjiweni eziyinkimbinkimbi.

Amamojula e-axis aqondile: I-X-axis (ukunyakaza okuseceleni), i-Y-axis (ukwelulwa phambili nangemuva), kanye ne-Z-axis (ukuphakamisa okuqondile) ngokuvamile zisebenzisa inhlanganisela yeziqondiso eziqondile eziqondile nezikulufi zebhola. Iziqondiso zenziwe ngensimbi eqinile ye-alloy enobuso obuqondile obuphansi. Uma zihlanganiswe nezilayidi ezinokulayisha kwangaphambili okulungisekayo, ziqinisekisa amaphutha okuqondile ngaphakathi kuka-0.02mm/m ngesikhathi sokunyakaza. Izikulufi zebhola zixhunywe ngqo ku-drive motor ngamantongomane, ziguqula ukunyakaza kokujikeleza kube ukufuduka okuqondile. Lokhu kufeza ukusebenza kahle kokudlulisela okungaphezu kuka-90%, okuphakeme kakhulu kunezinhlelo zendabuko ze-rack ne-pinion, kunciphisa ngempumelelo ukulahleka kwamandla.

Amajoyinti e-rotary axis: I-A-axis (ukujikeleza kwesihlakala) kanye ne-B-axis (ukujikijela ingalo) yizinto ezibalulekile zokulungisa ukuma okuyinkimbinkimbi. Ama-harmonic reducers anembile kakhulu asetshenziswa ngaphakathi kwamajoyinti, kanti i-backlash ilawulwa ngaphakathi komzuzu owodwa we-arc. Uma ihlanganiswe nomthamo we-radial kanye ne-axial wama-roller bearings ahlanganisiwe, aqinisekisa kokubili ukuphuma okuqinile kokujikeleza kanye nokunemba kokubeka okungu-0.1°. Ezimweni zokusebenza ngesivinini esikhulu, isivinini sokuphendula esiguquguqukayo se-rotation axis singafinyelela ku-500°/s, sihlangabezane nezidingo zokukhiqiza okusheshayo kokushintsha.

Uhlelo Lokushayela: "Izicubu Zemisipha" Zokukhipha Amandla

Uhlelo lokushayela lwerobhothi elinomugqa oqondile lusebenza "njengemisipha," lunikeza amandla alawulwa ngokunembile okunyakaza kwe-axis ngayinye. Njengamanje, izixazululo zokushayela ezijwayelekile zihlukaniswe njengama-servo motors nama-stepper motors. Ama-Servo drives, ngezinzuzo zawo ekulawuleni okuvaliwe, abusa ukukhiqizwa kokubumba komjovo okuphezulu.

Amayunithi okushayela i-Servo aqukethe i-servo motor, i-encoder, kanye nomshayeli. I-motor isebenzisa omakethi abangapheli be-rare earth, enikeza i-torque density ephezulu kanye nokukhishwa kwamandla okuzinzile ngisho nangesivinini esiphansi. Isixazululo se-encoder sivame ukufinyelela ama-bits angu-20 (ama-pulse angu-1,048,576 ngokujikeleza ngakunye). Kuhlanganiswe ne-algorithm yokulawula i-PID yomshayeli, lokhu kufeza iphutha lokulawula isikhundla elingu-≤0.01mm. Ezimweni zokususa izingxenye zesivinini esikhulu, izikhathi zokusheshisa kanye nokwehlisa ijubane zesistimu ye-servo zingalawulwa zingakapheli amasekhondi angu-0.1, izikhathi zomjikelezo wokuhlangana zidlula imijikelezo engu-120 ngomzuzu.

Umklamo Wokuxhumeka Kokudlulisa: Uhlelo lokushayela kanye ne-axis ehambayo kuxhunywe nge-coupling eguquguqukayo noma ibhande elihambisanayo. Ama-coupling anwebekayo angavala ukungalingani kokufakwa futhi anciphise umthelela wemithwalo yokushaqeka enjinini. Ama-drive ebhande ahambisanayo afanelekela ukudluliselwa kwamandla ebanga elide. Umzimba wawo webhande le-polyurethane kanye nesakhiwo sensimbi yocingo kuqinisekisa ukunemba kokudlulisela ngenkathi kumelana nokuguguleka kwamahora angaphezu kuka-10,000 okusebenza okuqhubekayo.

Isisebenzi Sokugcina: "Isandla" Sokuxhumana Kokusebenza

Isiphehli sokugcina (i-gripper) yingxenye esebenzisana ngqo ne- Ingalo Yerobhothi kanye nengxenye ebunjiwe ngomjovo. Ukwakheka kwayo kwesakhiwo kumele kwenziwe ngokwezifiso ngokwezici zomkhiqizo. Izinhlobo ezivamile zifaka ama-gripper omoya, izinkomishi zokudonsa i-vacuum, namadivayisi kazibuthe. Ukugxila kwayo okuyinhloko kukushintsha okusheshayo kanye nokusebenzisana okuzinzile nengalo yerobhothi.

Isakhiwo Somphumela Wokuphela: I-gripper yomoya isebenzisa i-dual-piston drive enebanga lamandla okubamba elilungisekayo elingu-5-500N. Ifakwe iminwe ye-silicone noma ye-polyurethane ukuze ifake izingxenye ezibunjiwe zezinto zokwakha nezimo ezahlukahlukene. Inkomishi yokumunca i-vacuum isebenzisa i-Venturi generator ukukhiqiza ingcindezi engemihle engu--80kPa. I-gripper eyodwa ingabamba ngaphezu kuka-5kg, okwenza ifaneleke kakhulu ezingxenyeni ezinkulu zepulasitiki ezisicaba. Amanye amamodeli aphezulu afakwe ama-interface ashintsha ngokushesha, anciphisa isikhathi sokushintsha sibe ngaphansi kwemizuzwana engama-30, okuhlangabezana nezidingo zokukhiqiza okuhlukahlukene kakhulu, okuphansi.

Umklamo wokulinganisela umthwalo: Kufakwa inzwa yomthwalo ekuxhumaneni phakathi kwe-effector yokugcina kanye nengalo ukuze kuqashwe isisindo sokubamba ngesikhathi sangempela. Lapho umthwalo udlula umkhawulo omisiwe (ngokuvamile u-120% womthwalo olinganisiwe), uhlelo luqala ngokuzenzakalelayo indlela yokuvikela, lumise ukunyakaza futhi lukhiphe i-alamu ukuvimbela umonakalo esakhiweni somshini ngenxa yokugcwala ngokweqile. Lo mklamo uvumela irobhothi ukuthi likwazi ukuthwala imithwalo esukela ku-5 kuya ku-50 kg, ehlanganisa izidingo zokukhiqiza ezisukela ezingxenyeni ezincane ze-elekthronikhi kuya ezingxenyeni ezinkulu zepulasitiki zezimoto.

Isakhiwo sokusekela: "Isitho somzimba" esiqinisekisa ukuzinza

Isakhiwo sokusekela sihlanganisa izingxenye ezithwala umthwalo njengesisekelo, amakholomu, kanye nemishayo. Ukuqina kwaso kanye nomklamo olula kuthinta ngqo ukunemba kokunyakaza kwerobhothi kanye nokusetshenziswa kwamandla. Amarobhothi esimanje ane-axis emihlanu ngokuvamile asebenzisa umklamo we-modular, esebenzisa ukuhlaziywa kwezinto ezilinganiselwe ukuze kuthuthukiswe ukusatshalaliswa kokucindezeleka kwesakhiwo.

Ukukhethwa kwezinto zokwakha nezinto zokwakha: Amakholomu kanye nemishayo ngokuvamile kwenziwa ngamaphrofayili e-aluminium alloy anamandla aphezulu (njenge-6061-T6), afakwe i-anodized kokubili ukugqwala kanye nokumelana nokuguguleka. Ukuqinisa insimbi kufakwe ezindaweni ezibalulekile ezithwala umthwalo, kunciphisa isisindo sonke ngo-30% ngenkathi kuqinisekiswa ukuguquguquka okungaguquki okungu-≤0.5mm/m. Isisekelo sakhiwe ngensimbi ephonswe, futhi ukwelashwa kokuguga kuqeda ukucindezeleka kwangaphakathi, kuqinisekisa ukuzinza kokusebenza.

Umklamo wokumunca nokudlidliza: Ama-pad okumunca ukushaqeka afakiwe ekuxhumaneni phakathi kwesakhiwo sokusekela nomhlabathi, amunca ngaphezu kwama-90% okudlidliza okuvama kakhulu. Izimbozo zokuvikela ezihlehliswayo zifakwe zizungeze izingxenye ezihambayo, ezakhiwe ngendwangu ye-nylon enezingqimba eziningi kanye nesakhiwo esihlanganisiwe sohlaka lwensimbi. Zifinyelela isilinganiso se-IP54 futhi zivikela ngempumelelo ekungcoleni kothuli namafutha endaweni yokubumba umjovo.

Inani Lokukhiqiza Elilethwa Izinzuzo Zesakhiwo

Umklamo womshini werobhothi lomshini wokubumba injection one-axis ezinhlanu ekugcineni usiza ekuthuthukiseni ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo. Ukuxhumana kwayo kwe-multi-axis kwandisa izinga lokwenza ngcono indlela yokususa izingxenye ngo-40%, okuvumela ukubamba izingxenye ngasikhathi sinye kusuka eziteshini eziningi ezikhumbeni eziyinkimbinkimbi ngaphandle kokuphazamiseka kwesikhala. Ukubeka ngokunemba okuphezulu (ukuphindeka ≤±0.05mm) kunciphisa ingozi yokushayisana phakathi kwezingxenye nezikhumbeni, kunciphisa izinga lokukhubazeka libe ngaphansi kuka-0.1%.
