Uphawu oluphambili lweefektri ezikrelekrele kukuzisebenzela ngokuzenzekelayo, ukwenziwa kwedijithali, kunye nobukrelekrele benkqubo yemveliso, kunye iirobhothi ze-servozii-hub eziphambili ezidibanisa umaleko wokuqonda kunye nomaleko wokwenza. Ngokungafaniyo nemveli Iirobhothi zomoya, iirobhothi ze-servo ziqhutywa ziimoto ze-servo, zidityaniswe neendlela zokudlulisa ezichanekileyo kunye neenkqubo zolawulo, okuvumela ulawulo oluchanekileyo lwendawo, isantya, kunye ne-torque. Olu phawu lobuchwephesha lubenza babe ngabathwali abaphambili "bemveliso eguquguqukayo" kwiifektri ezikrelekrele—bakwazi ukuphendula kwimiyalelo yexesha langempela evela kwinkqubo ye-MES ukulungisa iiparameter zokusebenza, kunye nokwenza ngcono iinkqubo zemveliso ngempendulo yedatha.

Kwindlela esebenza ngokuzenzekelayo kwiifektri zanamhlanje, iirobhothi ze-servo zenza imisebenzi ephambili efana nokuphathwa kwezinto, ukuhlanganiswa ngokuchanekileyo, kunye nokuhlolwa komgangatho. Ukusebenza kwazo kumisela ngokuthe ngqo ukusebenza kakuhle komgca wemveliso kunye nezinga lokufaneleka kwemveliso. Idatha ibonisa ukuba imigca yemveliso exhotyiswe ngeerobhothi ze-servo inokufikelela kumazinga okusetyenziswa kwezixhobo angaphezulu kwe-90%, idlula kakhulu i-60% yokusebenza ngesandla, ngelixa ilawula iimpazamo zemveliso ngaphakathi koluhlu lwe-micrometer. Ngokwenyani, iirobhothi ze-servo azisezizo nje izinto zokutshintsha izixhobo zesandla, kodwa zifana "nee-terminal nodes" ezinezakhono zokunxibelelana kwedatha kwiinethiwekhi zokuvelisa ezikrelekrele.

III. Iirobhothi zeServo ze-Three-Axis vs. Five-Axis: Umahluko kwezobuchwepheshe kunye nemida yokusetyenziswa

Umahluko ophambili phakathi kweerobhothi ze-servo ezine-axis ezintathu kunye ne-axis ezintlanu usekwe kumanqanaba azo enkululeko kunye neendlela zokuqhuba, ezimisela ngokuthe ngqo iimeko zesicelo sazo.Iirobhothi ze-Axis ikakhulu zizakhiwo ezinengalo enye, ezinamacandelo amabini, ezisebenzisa inkqubo yokuqhuba umoya kunye nombane exutyiweyo, ezixhotyiswe ngezinto zomoya ezingenisiweyo kunye neendlela zokwandisa isantya. Zibonakaliswa bubunzima obulula, ukungqubana okuphantsi, kunye nokuphendula ngokukhawuleza. Inzuzo yazo ephambili ikukugqiba imisebenzi elula nephindaphindayo ethe tye, njengokususa iindawo ezibunjiweyo ngenaliti kunye nezinto zokucwangcisa. Ngenxa yesakhiwo sazo esilula, iirobhothi ezinee-axis ezintathu zineendleko eziphantsi zokuthenga kunye nokugcina, nto leyo ezenza zifaneleke kwiimeko zemveliso ezinkulu ezineemfuno eziphantsi zobunzima bokusebenza.

Kwelinye icala, iirobhothi zeservo ezinee-axis ezintlanu zisebenzisa ii-servo drives zombane ngokupheleleyo kwaye zinoyilo olunezakhiwo ezimbini olunengalo ephambili kunye nengalo encedisayo. Iimoto zeservo ezintlanu zilawula ukuhambahamba, ukuphakamisa, kunye nokutsala, kwaye ezinye iimodeli ezineetoni eziphezulu nazo ziquka i-gripper rotation motor, nto leyo efikelela kukuguquguquka okukhulu kwintshukumo yendawo. Le nkqubo ye-servo drive epheleleyo ivumela ukuphumelela ngokuchanekileyo kunye nomthamo womthwalo, ifikelela kuchanekileyo oluphindaphindwayo lwe-±0.02mm, kwaye ivumela imisebenzi echanekileyo efana nokujika kwee-angle ezininzi kunye nokuhlanganiswa okuntsonkothileyo. Xa kuthelekiswa neemodeli ezinee-axis ezintathu, iirobhothi ezinee-axis ezintlanu zibonelela ngokuguquguquka okukhulu, zihambelana noomatshini bokucinezela abakhawulezayo, ukuchaneka Umatshini Wokubumba Ngenalitis, kunye nezinye izixhobo, nto leyo eyenza ukuba zifaneleke ngokukodwa ekususweni ngokukhawuleza kweemveliso ezibunjiweyo ezinodonga oluncinci kunye nokuhlanganiswa kwezinto ze-elektroniki ezichanekileyo.

Ukukhetha phakathi kwezi zimbini akukokuthelekisa nje ukugqwesa okanye ukungaziphathi kakuhle, kodwa kukuhambelana ngokuchanekileyo okusekelwe kwiimfuno zemveliso: xa umgca wemveliso usebenza ngokuyintloko kumjikelo oqhelekileyo, okhawulezayo, iirobhothi ezinee-axis ezintathu zibonelela ngexabiso elifanelekileyo; xa zijongene neemfuno zemveliso eziguquguqukayo zeemveliso ezahlukeneyo kunye nokuchaneka okuphezulu, iirobhothi ezinee-axis ezintlanu zidlala indima engenakutshintshwa.

IV. Ukwakhiwa kwakhona kwexabiso eliphambili: Indlela iTekhnoloji yeServo ephucula ngayo uKhuphiswano kwiFektri

Ukuphuculwa kwexabiso leengalo ze-servo robotic kwiifektri ezikrelekrele kubonakala kwiinkalo ezine: ukusebenza kakuhle, iindleko, umgangatho, kunye nokhuseleko, okwakha inkqubo yokwakha ngokutsha yokukhuphisana.

Zidibene nee-grippers zodidi lokutya, zifezekisa imisebenzi engenakuthintana ngokupheleleyo, zihlangabezana nemigangatho yokhuseleko lokutya.

VI. Isikhokelo soKhetho lweMveliso ekrelekrele: Ingqiqo yokwenza izigqibo ngokusekelwe kwiimfuno

Xa kukhethwa iingalo zerobhothi ze-servo kwiifektri ezikrelekrele, kufuneka kusekwe ingqiqo yokwenza izigqibo "ejolise kwimfuno" ukuze kuthintelwe ukulandela ngokungaboniyo iiparameter zokusebenza okuphezulu. Okokuqala, iiparameter zemveliso eziphambili kufuneka zichazwe ngokucacileyo: kwimisebenzi efuna ukuchaneka okungaphezulu kwe-±0.1mm kunye neentshukumo ezintsonkothileyo zendawo, imodeli ye-full-servo ye-axis ezintlanu kufuneka ibekwe phambili; kwimisebenzi elula ethe tye enamaxesha omjikelo azinzileyo, ingalo yerobhothi ye-axis ezintathu inikezela ngokusebenza ngcono kweendleko. Umthamo womthwalo kufuneka uqwalaselwe ngexesha lokukhetha. Ngokubanzi, ishishini le-elektroniki lidla ngokusebenzisa iimodeli zomthwalo ze-5-10kg, ngelixa ishishini leemoto lifuna iimodeli ezinomthamo womthwalo we-50kg okanye ngaphezulu.

Okwesibini, ukuhambelana kokudibanisa kufuneka kuvavanywe. Iingalo zerobhothi ze-servo ezikumgangatho ophezulu kufuneka zixhase iiprotokholi zonxibelelwano lwemizi-mveliso eziphambili ezifana ne-PROFIBUS kunye ne-Ethernet, okuvumela ukuhlanganiswa okungenamthungo neenkqubo ze-MES kunye ne-ERP zomzi-mveliso ukuze kusetyenziswe idatha ngexesha langempela kunye nokubeka esweni kude. Phantsi kweemfuno zemveliso eziguquguqukayo, ukuguquguquka kweprogram yengalo yerobhothi nako kufuneka kuqwalaselwe. Iimodeli ezixhasa iindlela ezininzi ezizinzileyo kunye neendlela zokuzihlela zinokuziqhelanisa ngokukhawuleza neemfuno zokutshintsha imveliso.

Ixabiso elipheleleyo lobomi yinto ebalulekileyo ekukhetheni imveliso. Ngaphandle kweendleko zokuthenga, ukulula kokugcinwa kubalulekile - uyilo lweemodyuli kunye nezixhobo zokunxiba ezihambelanayo ngokubanzi zinciphisa iindleko zokugcinwa okuqhubekayo; iimveliso ezinexesha eliphakathi phakathi kokusilela (MTBF) ezidlula iiyure ezili-10,000 zinciphisa ilahleko yexesha lokungasebenzi. Okokugqibela, ukhuseleko kunye nokuthobela imithetho kubaluleke kakhulu; iimveliso kufuneka zihlangabezane nemigangatho yokhuseleko yamazwe ngamazwe efana ne-ISO 10218 ukuqinisekisa ukusetyenziswa okufanelekileyo kwiifektri kumazwe ahlukeneyo nakwiindawo ezahlukeneyo.
