Vim li cas laser txiav tshuab xav tau sensors?
Nyob rau hauv cov txheej txheem txiav ntawm lub laser txiav tshuab, qhov kev ncua deb ntawm lub taub hau txiav thiab lub workpiece thiab ntsug degree ntawm lub nozzle thiab lub workpiece nto yog ob qho tseem ceeb heev, uas yuav ncaj qha cuam tshuam rau kev ua tau zoo, thiaj li yuav txhim kho cov khoom. txiav qhov zoo thiab txo cov tiam ntawm cov khoom pov tseg, nws yog ib qho tsim nyog yuav tsum tau nruab qee qhov tshwj xeeb sensors ntawm lub taub hau txiav kom paub tseeb tias nws tuaj yeem tsim cov khoom ruaj khov thiab zoo ib yam thiab ua kom muaj kev nyab xeeb ntawm cov txheej txheem.
Thaum cov duab ntawm lub laser txiav lub taub hau hloov thiab muaj qhov tsis sib xws ntawm cov teeb meem ntawm qhov chaw, lub sensor yuav pom qhov kev hloov no thiab txiav qhov siab raws li qhov kev hloov pauv, yog li ntawd nws yeej ib txwm ua raws li qhov kev ncua deb ntawm lub workpiece nto, yog li ntawd. tias cov khoom tuaj yeem ua tiav sai dua nyob rau hauv rooj plaub ntawm kev saib xyuas tsis tu ncua.
Kev ntsuas kev txav chaw yog qhov yooj yim tshaj plaws ntsuas kev ua haujlwm. Raws li seb lub sensor puas nyob rau hauv kev sib cuag nrog lub workpiece yuav tsum tau ntsuas, lub displacement sensor yuav muab faib ua kev sib cuag thiab tsis sib cuag ob hom. Tsis tiv tauj sensors lav siab daws teeb meem piv rau kev sib cuag sensors. Nyob rau tib lub sij hawm, nws muaj cov yam ntxwv ntawm ceev ceev dynamic teb thiab me me hysteresis yuam kev.
Cov sensors tsis sib cuag, qee zaum hu ua qhov sib thooj sensors, yog thawj zaug siv los ua qhov sib thooj sib txuas, uas yog, thaum cov khoom nyob rau hauv kev sim ze rau qee qhov kev ncua deb ntawm qhov kev sojntsuam rhiab, lub teeb liab hloov tau muab. Tam sim no qhov sib thooj sensors tau tsim los tsis tsuas yog kuaj pom qhov muaj lossis tsis muaj cov khoom, tab sis kuj muab qhov kev ncua deb ntawm cov khoom thiab cov kev sojntsuam rhiab, thiab muab cov ntaub ntawv hais txog cov duab thiab qhov chaw ntawm lub workpiece.
Vim tias nws tuaj yeem siv los ntsuas qhov kev hloov pauv ntawm cov khoom txav mus los, hom sensor no tseem hu ua lub sensor tsis sib cuag. Cov kev hloov pauv feem ntau suav nrog hysteresis hloov chaw sensor, eddy tam sim no hloov chaw sensor, capacitive hloov chaw sensor thiab inductive hloov pauv sensor. Sensors, thiab lwm yam.
Capacitive sensors muaj siab rhiab heev thiab cov yam ntxwv hauv qab no:
1: Zoo dynamic teb, vim hais tias cov electrostatic attraction ntawm daim hlau yog heev me me, lub zog yuav tsum tau tsawg heev, thiab lub movable feem yuav ua rau ib tug me me thiab nyias, yog li nws lub ntuj zaus yog siab thiab dynamic teb lub sij hawm yog. luv.
2: Cov qauv yooj yim, muaj zog yoog raws, yooj yim rau kev tsim, yooj yim los xyuas kom meej siab, tuaj yeem ua rau me me sensors, ua tiav qhov ntsuas tshwj xeeb, tuaj yeem ua haujlwm kub thiab qis, muaj zog hluav taws xob thiab muaj zog sib nqus thiab lwm qhov chaw hnyav, thiab tuaj yeem tiv taus siab, siab cuam tshuam, overload thiab lwm yam.
3: Lub tshav kub me me, thiab qhov kub ntawm nws tus kheej yog me me. Txij li thaum tus nqi capacitance ntawm lub capacitive sensor yog ywj siab ntawm cov khoom siv electrode, cov ntaub ntawv uas tsis tshua muaj kub coefficient tuaj yeem raug xaiv los ua kom muaj kev ruaj ntseg zoo thaum qhov kub thiab txias sab nraud.
