Kev Taw Qhia
Raws li ib feem tseem ceeb ntawm kev tswj hwm lub voj voog meej, qhov sib txawv ntawm qhov sib cuag yog qhov tseem ceeb hauv kev txiav txim siab qhov ua tau zoo ntawm lub micro switch, uas cuam tshuam ncaj qha rau qhov rhiab heev, lub neej ntev thiab kev hloov pauv ib puag ncig. Nrog rau qhov kev thov kom muaj miniaturization thiab kev ntseeg siab siab hauv kev lag luam automation thiab cov khoom siv hluav taws xob, kev tsim thiab kev siv ntawm qhov sib cuag tau dhau los ua qhov tseem ceeb ntawm kev sib tw thev naus laus zis hauv kev lag luam. Tsab xov xwm no yuav muab cov qauv kev lag luam thiab cov xwm txheej tshiab los tshuaj xyuas cov yam ntxwv kev siv thiab kev siv logic ntawm qhov sib cuag.
Cov Hom thiab Cov Yam Ntxwv ntawm Kev Sib Txuas Lus
Qhov sib nrug ntawm cov micro switches feem ntau yog muab faib ua plaub pawg, npog tag nrho cov xwm txheej ntawm qhov tseeb siab mus rau qhov tsis kam siab, thiab plaub hom yog 0.25mm chav kawm, 0.5mm chav kawm, 1.0mm chav kawm, thiab 1.8mm chav kawm, raws li. Qhov rhiab heev thiab kev poob siab tsis kam ntawm microswitches tsis sib raug zoo nrog lub suab sib cuag; 0.25mm lub suab sib cuag muaj qhov tsim qauv me me thiab muaj kev rhiab heev (lub zog ua haujlwm ≤ 0.1N), tab sis nws qhov kev poob siab thiab kev co tsis muaj zog. Feem ntau siv rau hauv cov khoom siv kho mob (xws li cov yuam sij phais), qhov ua kom pom tseeb ntawm lub sensor, thiab lwm yam, yuav tsum tswj hwm qhov tam sim no (≤ 0.1A) kom txo qhov poob ntawm kev sib cuag. Qhov sib cuag ntawm 0.55mm theem yog tus qauv dav dav hauv kev lag luam los sib npaug qhov rhiab heev thiab kev ruaj khov, thiab nws lub neej kho tshuab tuaj yeem ncav cuag ntau dua 5 lab zaug. Feem ntau siv rau hauv cov khoom siv hluav taws xob (cov nyees khawm nas), kev tswj hwm khoom siv hauv tsev (microwave qhov rooj hloov pauv) thiab lwm yam xwm txheej tam sim no qis mus rau nruab nrab. Qhov sib nrug ntawm 1.0 hli ua rau muaj zog tiv taus kev co (kev tiv taus kev co ≥ 50G) thiab txhawb kev tawg ntawm cov dej ntws siab dua 10A, tab sis nrog qhov teb qeeb me ntsis. Feem ntau siv rau hauv cov tshuab hloov pauv txwv kev lag luam, kev tiv thaiv kev nres tsheb fais fab tshiab, thiab lwm yam. Qhov sib nrug ntawm 1.8 hli muaj qhov tsim loj, qhov tsis kam arc nce 50%, tsim nyog rau cov xwm txheej siab qhib-tawm ntau zaus. Feem ntau siv rau hauv cov hluav taws xob system circuit breakers, cov tshuab hnyav (crane limit detection) thiab lwm yam chaw ib puag ncig hnyav.
Cov Kev Cov nyom ntawm kev siv tshuab thiab cov kev taw qhia tshiab
Txawm hais tias kev txo qis ntawm qhov sib cuag tuaj yeem txhim kho qhov rhiab heev, nws ntsib ob qhov teeb meem loj: 1. Arc erosion: Hauv cov xwm txheej siab-tam sim no, qhov me me yog qhov yooj yim rau oxidation ntawm cov neeg sib cuag vim yog arc erosion, uas ua rau lub neej luv ntawm kev sib cuag. Cov kev daws teeb meem suav nrog cov nyiaj-nickel alloy sib cuag thiab ceramic interrupter tsim, uas tuaj yeem ntev lub neej hluav taws xob mus rau ntau dua 500,000 zaug. 2. Kev kam rau ib puag ncig: kev co thiab kev poob siab yog qhov yooj yim rau kev ua yuam kev. Cov chaw tsim khoom tau ua kom zoo dua reed preload caij nplooj ntoos hlav lub zog (piv txwv li, Honeywell's V15 series) thiab cov qauv damping los txhim kho qhov kev tiv thaiv kev co ntawm 1.0mm suab hloov los ntawm 40%.
Cov Qauv Siv Hauv Kev Lag Luam
Kev txhim kho ntse: Micro switches nrog cov chips sensing pressure sensing (xws li Tesla Optimus robot fingertip module) paub txog kev tswj hwm adaptive los ntawm kev kho qhov suab los ntawm kev saib xyuas lub sijhawm tiag tiag ntawm cov xwm txheej sib cuag.
Kev tsim khoom ntsuab: EU RoHS 3.0 txhawb kom muaj kev nrov npe ntawm cov ntaub ntawv tiv tauj tsis muaj cadmium, thiab 0.5 hli suab hloov pauv ua tus thawj coj hauv kev siv cov hlau nyiaj uas zoo rau ib puag ncig, xav txog ob qho tib si kev ua tau zoo thiab kev ua raws li txoj cai.
Xaus lus
Txij li qhov tseeb ntawm cov khoom siv kho mob millimeter mus rau txhiab phaus ntawm kev lag luam hnyav, kev hloov pauv thev naus laus zis ntawm micro switch contact pitch qhia txog kev lag luam tsim khoom qhov kev nrhiav qhov tseeb thiab kev ntseeg siab. Yav tom ntej, nrog kev koom ua ke ntawm cov khoom siv tshawb fawb thiab cov algorithms ntse, qhov "microscopic parameter" no yuav txuas ntxiv txhawb nqa kev txhim kho ntawm cov saw hlau kev lag luam thoob ntiaj teb.
