Nyob rau hauv lub nce toj toj roob hauv pes ntawm kev lag luam kev lag luam, qhov flatness ntawm cov khoom nto yog qhov tseem ceeb ntawm cov khoom zoo. Flatness detection yog dav siv nyob rau hauv ntau yam lag luam, xws li automotive manufacturing, aerospace, thiab electronics. Piv txwv xws li kev soj ntsuam flatness ntawm cov roj teeb lossis cov xov tooj ntawm tes hauv kev lag luam lub cev muaj zog, thiab kev soj ntsuam flatness ntawm LCD panels hauv kev lag luam semiconductor.
Txawm li cas los xij, cov txheej txheem nrhiav kom pom kev ncaj ncees raug kev txom nyem los ntawm cov teeb meem xws li kev ua haujlwm tsis zoo thiab qhov tsis zoo. Nyob rau hauv sib piv, LVDT (Linear Variable Differential Transformer) sensors, nrog rau lawv qhov zoo ntawm high precision, siab ntseeg, thiab frictionless ntsuas (piv txwv li: LVDTs siv ib tug sojntsuam tiv tauj cov khoom nto, tsav lub core displacement mus cuag frictionless thiab high-precision ntsuas), yog tam sim no dav siv nyob rau hauv niaj hnub khoom flatness nrhiav kom tau.
Txoj Cai Kev Ua Haujlwm:
Frictionless ntsuas:Feem ntau tsis muaj kev sib cuag ntawm lub cev ntawm lub cev txav tau thiab cov qauv coil, txhais tau tias LVDT yog cov khoom siv tsis muaj kev sib txhuam.
Unlimited Mechanical Life: Vim tias ib txwm tsis muaj kev sib cuag ntawm LVDT cov tub ntxhais thiab cov qauv coil, tsis muaj qhov chaw tuaj yeem rub ua ke lossis hnav tawm, muab LVDTs ib qho tseem ceeb tsis muaj kev txwv lub neej.
Kev daws teeb meem tsis kawg: LVDTs tuaj yeem ntsuas qhov kev hloov pauv me me hauv qhov tseem ceeb vim tias lawv ua haujlwm ntawm electromagnetic coupling cov qauv hauv cov qauv tsis muaj kev sib txhuam.Qhov tsuas yog kev daws teeb meem yog lub suab nrov hauv lub teeb liab txias thiab kev daws teeb meem ntawm cov khoom tso tawm.
Null Point Repeatability:Qhov chaw ntawm LVDT qhov tseem ceeb ntawm qhov tsis muaj tseeb yog qhov ruaj khov thiab rov ua dua, txawm tias dhau ntawm nws qhov kev ua haujlwm kub ntau heev.Qhov no ua rau LVDTs ua tau zoo raws li qhov tsis zoo ntawm qhov chaw sensors hauv lub voj kaw kaw.
Hla-Axis Rejection:LVDTs yog cov rhiab heev rau axial txav ntawm cov tub ntxhais thiab kuj tsis hnov tsw rau radial txav.
Fast Dynamic Teb:Qhov tsis muaj kev sib txhuam thaum lub sijhawm ua haujlwm zoo ib yam tso cai rau LVDT los teb sai heev rau kev hloov pauv hauv txoj haujlwm tseem ceeb.Cov lus teb dynamic ntawm LVDT sensor nws tus kheej tsuas yog txwv los ntawm inertial teebmeem ntawm cov tub ntxhais me me.
Cov zis tsis txaus:LVDT tso zis yog ib qho analog teeb liab ncaj qha ntsig txog txoj hauj lwm. Yog tias muaj hluav taws xob tawm, kev ntsuas tuaj yeem rov pib dua yam tsis muaj kev rov ua dua (lub hwj chim yuav tsum tau tig rov qab kom tau txais tus nqi tam sim no tom qab hluav taws xob tawm).
- Workpiece Nto Flatness Detection: Los ntawm kev tiv tauj saum npoo ntawm ib qho chaw ua haujlwm nrog LVDT sojntsuam, qhov siab hloov pauv ntawm qhov chaw tuaj yeem ntsuas tau, yog li ntsuas nws qhov flatness.
- Sheet Hlau Flatness Detection: Thaum lub sij hawm daim ntawv hlau ntau lawm, ib qho arrayed LVDT layout, ua ke nrog ib tug automated scanning mechanism, muaj peev xwm ua tau tag nrho-sov flatness daim ntawv qhia ntawm cov ntawv loj loj.
- Wafer Flatness Detection:Hauv kev lag luam semiconductor, qhov flatness ntawm wafers muaj kev cuam tshuam loj rau kev ua haujlwm ntawm nti. LVDTs tuaj yeem siv los ntsuas qhov flatness ntawm wafer nto. (Ceeb Toom: Hauv kev tshawb nrhiav wafer flatness, LVDT yuav tsum tau nruab nrog lub teeb yuag probes thiab tsis tshua muaj kev sib cuag quab yuam tsim, ua rau nws tsim nyog rau cov xwm txheej uas tsis muaj kev puas tsuaj rau saum npoo.)
- Micrometer-level repeatability
- Ntau yam muaj nyob ntawm 5-20mm
- Cov kev xaiv tso zis ntau, suav nrog cov teeb liab digital, analog, thiab 485.
- Tsawg li 3N sensing lub taub hau siab, muaj peev xwm ntawm tsis-abrasive nrhiav tau ntawm ob lub iav hlau.
- Kev nplua nuj sab nrauv qhov ntev kom tau raws li ntau qhov chaw thov.
- Cov lus qhia xaiv
