Kwa zaka zambiri, mlatho woyenda kapena mtanda wa gantry pa nsanja yothamanga kwambiri nthawi zambiri unkakhala chitsulo kapena aluminiyamu, makamaka chifukwa chakuti unali wodziwika bwino komanso wosavuta kupeza. Zimenezo zikusintha pang'onopang'ono kudutsazida zolondolamafakitale, ndipo chifukwa chake ndi chiŵerengero chapadera cha uinjiniya: kuuma kwa kulemera.
Chitsulo chili ndi kuuma kwakukulu, koma ndi cholemera. Aluminiyamu ndi yopepuka koma yolimba pang'ono, kotero mtanda wa aluminiyamu wofanana ndi wachitsulo nthawi zambiri umakhala wolemera kwambiri ukaukhuthala kuti ugwirizane ndi izi. Miyala ya ulusi wa kaboni imathetsa kusinthana kumeneko. Mtanda wa ulusi wa kaboni wopangidwa bwino ukhoza kufanana kapena kupitirira kuuma kwa mtanda wa aluminiyamu pafupifupi gawo limodzi mwa magawo atatu a kulemera kwake, chifukwa mawonekedwe a ulusi amatha kupangidwa ndi wosanjikiza ndi wosanjikiza kuti asapindike makamaka motsatira mzere wofunikira, m'malo modalira zinthu zofanana mbali zonse monga momwe chitsulo chimachitira.
Chifukwa chiyani kulemera kuli kofunika kwambiri kuposa momwe kumamvekera ngati kuyenera kukhalira
Pa makina oyendera a XY okhala ndi mawonekedwe a gantry, kuwala pakati pa ma axes awiri olunjika kumakhala kosuntha nthawi iliyonse makinawo akamalemba. Dulani kulemerako ndi theka kapena kuposerapo, ndipo ma servo motors safunika kugwira ntchito molimbika kuti afulumizitse ndikuchepetsa mphamvu yake, nthawi yokhazikika ikatha kusuntha kulikonse, ndipo makina onse amatha kuyendetsa mwachangu popanda kukweza mphamvu ya drive train. Mu ntchito monga kudula kwa laser kwa flying-optics, kuboola PCB mwachangu, ndi kusonkhanitsa pick-and-place - komwe makina amatha kuchita masauzande ambiri pa shift iliyonse - kumeta ma milliseconds pa chochitika chilichonse chokhazikika kumawonjezera phindu lalikulu pakupanga kwathunthu.
Pali phindu lina lomwe silimalandira chisamaliro chochuluka: ulusi wa kaboni uli ndi kutentha kochepa kwambiri pamlingo wake wa ulusi, m'malo ena omwe amayandikira zero, zomwe zimakhala bwino kwambiri kuposa aluminiyamu pafupifupi 23 x 10⁻⁶ pa °C. Pa mtengo womwe umakula mita imodzi kapena kuposerapo ndipo umafunika kubwerezabwereza pamalo pomwe kutentha kwa mlengalenga kumasinthasintha madigiri angapo, kukhazikika kumeneko ndikofunikira monga momwe zimakhalira ndi kusunga kulemera.
Zosinthazo ndi zenizeni
Matabwa a ulusi wa kaboni si okonzedwanso padziko lonse lapansi. Amawononga ndalama zambiri popanga kuposa gawo la aluminiyamu lotulutsidwa, kapangidwe kake ndi njira yoyikiramo zinthu zimafuna uinjiniya wapadera osati zinthu zomwe sizinakonzedwe kale, ndipo kukonzanso pambuyo pogundana ndi chinthu sikuli bwino kwambiri kuposa ndi chitsulo - mtengo wa aluminiyamu wowonongeka nthawi zambiri umatha kukonzedwanso, pomwe mtengo wophatikizika wowonongeka nthawi zambiri umafunika kusinthidwa. Pazida zothamanga pang'ono komanso zolondola kwambiri pomwe mtengo wake suli wolondola chifukwa cha kuchuluka kwa zinthu kapena kulondola, aluminiyamu imakhalabe yokhazikika.
Kumene ukadaulo ukupita
Njira yodziwika bwino yogwiritsira ntchito magetsi pakadali pano ili mu makina opangira ma laser othamanga kwambiri, ma robot othamanga kwambiri, ndi zida zowunikira ma semiconductor, komwe opanga makina amakhala pansi pa kukakamizidwa kosalekeza kuti awonjezere mayendedwe pamphindi popanda kuwononga kulondola kwa malo. Pamene njira zoyika ulusi wa kaboni zikuchulukirachulukira ndipo ndalama zikupitirira kutsika kuchokera pomwe zinali zaka khumi zapitazo, ndikwanzeru kuti miyala yophatikizika isunthe kuchoka pa chinthu cha "premium option" kupita ku chinthu chokhazikika pamakina aliwonse oyendera komwe liwiro ndi kulondola zonse ndizofunikira - momwe maziko a granite adasinthira kuchoka pa chinthu chapadera kupita ku muyezo wamakampani oyezera poyerekeza ndi mbadwo wakale wa zida.
