1. Pressure sensor yamakina a SMT
Sankhani ndi kuika makina, kuphatikizapo masilindala osiyanasiyana ndi ma jenereta a vacuum, ali ndi zofunikira zina za kuthamanga kwa mpweya, zotsika kusiyana ndi kukakamizidwa kwa zipangizo, makinawo sangathe kugwira ntchito bwinobwino.Masensa opanikizika nthawi zonse amayang'anitsitsa kusintha kwa kuthamanga, kamodzi kosadziwika, ndiko kuti, alamu yapanthawi yake, imakumbutsa wogwiritsa ntchitoyo kuti athane ndi nthawi yake.
2. Kusokoneza maganizo kwa makina a SMT
Thenozzle woyamwamakina a SMT amatenga zigawo zake ndi kukakamiza koyipa, komwe kumapangidwa ndi jenereta yoyipa (jenereta ya jet vacuum) ndi sensor vacuum.Ngati kupanikizika koipa sikukwanira, zigawozo sizidzatengeka.Ngati mulibe zigawo mu feeder kapena zigawo zake zakhazikika mu thumba lazinthu ndipo sizingayamwidwe, bubu loyamwa silingalowe.Izi zidzakhudza magwiridwe antchito a makina.The negative pressure sensor nthawi zonse imayang'anira kusintha kwa kupanikizika koyipa, ndipo pamene zoyamwitsa kapena zoyamwitsa sizikupezeka, zimatha kupereka alamu munthawi yake kukumbutsa woyendetsa kuti alowe m'malo mwa wodyetsa kapena kuyang'ana ngati njira yotseketsa yatsekeka.
3. Sensa ya malo a SMT makina
Kutumiza ndi kuyika kwa bolodi losindikizidwa, kuphatikizapo kuwerengera kwa PCB, kuzindikira nthawi yeniyeni ya mutu wa SMT ndi kayendetsedwe ka ntchito, ndi kayendetsedwe ka njira zothandizira, zimakhala ndi zofunikira kwambiri pa malo, zomwe ziyenera kuzindikiridwa ndi mitundu yosiyanasiyana ya masensa a malo.
4. Chithunzi chojambula cha makina a SMT
Sensa yazithunzi ya CCD imagwiritsidwa ntchito kuwonetsa momwe makina a SMT amagwirira ntchito munthawi yeniyeni.Itha kusonkhanitsa mitundu yonse yazizindikiro zazithunzi zomwe zimafunikira, kuphatikiza malo a PCB ndi kukula kwa chipangizocho, ndikupanga kusintha ndi SMT kwa mutu wa chigamba kumalizidwa ndi kusanthula ndi kukonza makompyuta.
5. Laser sensor ya SMT makina
Laser yakhala ikugwiritsidwa ntchito kwambiri mu makina a SMT, imatha kuthandizira kuweruza mawonekedwe a coplanar a zikhomo za chipangizocho.Mukathamangira pamalo a sensor ya laser yomwe imayang'anira chipangizo chomwe chikuyesedwa, chotulutsidwa ndi mtengo wa laser mu zikhomo za IC ndikuwonetsa kwa laser pa owerenga, ngati kutalika kwa mtengowo kuli kofanana ndi mtengo, coplanarity wa chipangizocho ndi woyenerera, ngati sichomwecho, chifukwa chopindika pa pini, pangani kuwala kowala kutalika, sensor laser kuzindikira pini ya chipangizocho ndi yolakwika.Komanso, sensor laser imatha kuzindikira kutalika kwa chipangizocho, chomwe chingachepetse nthawi yotsogolera.
6. Sensa ya m'dera la makina a SMT
Pamene makina a SMT akugwira ntchito, kuti amamatire mutu wa ntchito yotetezeka, nthawi zambiri mutu wa malo oyendayenda uli ndi masensa, kugwiritsa ntchito mfundo ya photoelectric kuyang'anira malo ogwirira ntchito, kuteteza kuwonongeka kwa zinthu zakunja.
7. Gwirizanitsani mphamvu ya sensor ya mutu wa kanema
Ndi kusintha kwa liwiro ndi kulondola kwa chigambacho, "mphamvu yoyamwa ndi kumasula" ya mutu wa chigamba kuti igwirizane ndi zigawozo ku PCB ikufunika kwambiri, yomwe imatchedwa "Z-axis soft landing function".Zimazindikirika kudzera muzonyamula katundu wa hall pressure sensor ndi servo motor.chigawocho chikayikidwa pa PCB, chidzagwedezeka panthawiyo, ndipo mphamvu yake yogwedezeka imatha kuperekedwa ku dongosolo lolamulira mu nthawi, kenako ndikubwezeredwa kumutu wa chigamba kupyolera mu kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake, kuti azindikire z-axis yofewa yotera ntchito.Pamene mutu wa chigamba ndi ntchitoyi ukugwira ntchito, umapereka kumverera kosalala komanso kopepuka.Ngati kuyang'anitsitsa kumapangidwa, kuya kwa malekezero awiri a chigawo chomizidwa mu solder phala ndi pafupifupi chimodzimodzi, zomwe zimapindulitsa kwambiri kupewa "chikumbutso" ndi zolakwika zina zowotcherera.Popanda mphamvu ya sensor, pakhoza kukhala kusuntha kuti muwuluke.
