Choncho, deta ya sensa imathandizira mapasa adijito, komanso ulusi wa digito womwe umaphatikizapo kupanga, kupanga, ntchito zautumiki ndi kutha.Zikawunikidwa pogwiritsa ntchito luntha lochita kupanga ndi kuphunzira makina, deta iyi imabwereranso ku mapangidwe ndi kukonza, kupititsa patsogolo ntchito ndi kukhazikika. yasinthanso momwe maunyolo amagwirira ntchito limodzi.Mwachitsanzo, wopanga zomatira Kiilto (Tampere, Finland) amagwiritsa ntchito masensa a Collo kuthandiza makasitomala ake kuwongolera chiŵerengero cha zigawo A, B, ndi zina zambiri m'zida zawo zophatikizira zomatira zamitundu yambiri." Kiilto tsopano akhoza kusintha zomatira zake kwa makasitomala payekhapayekha, akutero Järveläinen, "komanso zimathandiza Kiilto kumvetsetsa momwe utomoni umagwirira ntchito mukasitomala, komanso momwe makasitomala amalumikizirana ndi makasitomala. mankhwala awo, zomwe zikusintha momwe kuperekera kumapangidwira. Unyolo ukhoza kugwirira ntchito limodzi. "
OPTO-Light imagwiritsa ntchito masensa a Kistler, Netzsch ndi Synthesites kuyang'anira kuchiritsa kwa magawo a epoxy a CFRP opangidwa ndi thermoplastic. Ngongole ya zithunzi: AZL
Zoseweretsa zimathandiziranso zinthu zatsopano zatsopano komanso kuphatikiza njira.Zofotokozedwa mu CW's 2019 projekiti ya OPTO-Light (onani "Thermoplastic Overmolding Thermosets, 2-Minute Cycle, One Battery"), AZL Aachen (Aachen, Germany) imagwiritsa ntchito masitepe awiri. ndondomeko kuti horizontally compress limodzi Kuti (UD) mpweya CHIKWANGWANI/epoxy prepreg, ndiye overmolded ndi 30% ulusi wamagalasi amfupi olimbikitsidwa PA6.Mfungulo ndikungochiritsa pang'ono prepreg kuti reactivity yotsalira mu epoxy athe kulumikiza ku thermoplastic.AZL amagwiritsa Optimold ndi Netzsch DEA288 Epsilon analyzers ndi Synthesites ndi Netzsch dielectric masensa ndi Kistler mu -masensa a nkhungu ndi pulogalamu ya DataFlow kuti mukonzekere jekeseni. ”Muyenera kukhala nazo kumvetsetsa mozama za prepreg psinjika akamaumba ndondomeko chifukwa muyenera kuonetsetsa inu kumvetsa mkhalidwe wa machiritso kuti mukwaniritse kugwirizana bwino thermoplastic overmolding, "akufotokoza AZL kafukufuku injiniya Richard Schares. "M'tsogolomu, njirayi ikhoza kukhala yosinthika komanso yanzeru, kusinthasintha kwazinthu kumayambitsidwa ndi ma sensor."
Komabe, pali vuto lalikulu, akutero Järveläinen, “ndipo kusamvetsetsa kwa makasitomala za momwe angaphatikizire masensa osiyanasiyanawa m'njira zawo. Makampani ambiri alibe akatswiri a masensa. ” Pakalipano, njira yopita patsogolo imafuna opanga masensa ndi makasitomala Kusinthanitsa zambiri mmbuyo ndi mtsogolo.Mabungwe monga AZL, DLR (Augsburg, Germany) ndi NCC akupanga ukadaulo wa masensa ambiri.Sause adati pali magulu mkati mwa UNA, komanso spin-off. makampani omwe amapereka kuphatikizika kwa sensa ndi ntchito zamapasa zama digito.Anawonjezeranso kuti maukonde opanga ma Augsburg AI adabwereka malo a 7,000-square-metres kuti achite izi, "kukulitsa. Ndondomeko yachitukuko ya CosiMo pamlingo waukulu kwambiri, kuphatikiza ma cell olumikizana ndi makina, komwe ogwira nawo ntchito azigawo amatha Kuyika makina, kuyendetsa mapulojekiti ndikuphunzira momwe angaphatikizire njira zatsopano za AI. ”
Carapappas adanena kuti chiwonetsero cha dielectric sensor cha Meggitt ku NCC chinali sitepe yoyamba. chosowa ndi zipangizo kuyitanitsa. Digital automation ikukula. ”
