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 zotero. tsopano ikhoza kusintha zomatira zake kwa makasitomala aliyense," akutero Järveläinen, "komanso zimathandiza Kiilto kumvetsetsa momwe utomoni umagwirira ntchito pamakasitomala, komanso momwe makasitomala amalumikizirana ndi zinthu zawo, 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% yochepa galasi CHIKWANGWANI analimbitsa PA6. Chinsinsi ndi pang'ono kuchiritsa prepreg kuti reactivity otsala mu epoxy athe kugwirizana kwa thermoplastic .AZL imagwiritsa ntchito Optimold ndi Netzsch DEA288 Epsilon analyzers yokhala ndi ma Synthesites ndi Netzsch dielectric sensors ndi Kistler in-mold sensors ndi DataFlow software kuti muwongolere jekeseni jekeseni. kumvetsetsa momwe machiritso amathandizira kuti agwirizane bwino ndi kutenthedwa kwa thermoplastic," akufotokoza motero katswiri wofufuza wa AZL 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. Ananenanso kuti maukonde opanga Augsburg AI adabwereka malo okwana 7,000-square-metres kuti achite izi, "kukulitsa mapulani a chitukuko cha CosiMo pamlingo waukulu kwambiri, kuphatikiza ma cell olumikizidwa, komwe ogwira nawo ntchito m'mafakitale. Mutha Kuyika makina, kuyendetsa ntchito ndikuphunzira momwe mungaphatikizire 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. ”
