Nyob rau hauv kev xyaum ntawm lithography, "tuav" yog luam tawm cov teeb meem zoo uas feem ntau tshwm sim thiab yog nyuaj rau tag nrho daws. Kev tsim cov "bars" muaj ntau yam xws li tsim cov tshuab luam ntawv, cov ntaub ntawv thiab kev siv technology ntawm cov khoom siv sib xyaw, kev ua haujlwm ntawm cov neeg ua haujlwm, xaiv cov ntawv luam tawm, thiab kev kho cov khoom siv dag zog. Lub hauv paus loj rau qhov "bars" hauv kev luam yog qhov kev vibration generated ntawm lub luam tawm xovxwm ntawm lub tshuab luam ntawv thiab cov inking, kev xa dej dej, lossis cov ntawv xa kev sib txuas, ua rau qhov chaw nyob ntawm tus luam kom qis. Yog li no, peb cov khoom siv lithographic thiab tshuab tsis muaj peev xwm tshem tawm tsis tau "bar", thiab tsuas yog los ntawm kev txhim kho technology thiab kev siv tshuab kom txo tau thiab txo qhov "bar". Tsab xov xwm no tshab txhais txog kev tsim thiab kev daws teeb meem ntawm "tuav" thiab kev cia siab ua si lub luag haujlwm hauv kev nyiam jade.
1. Lub tswvyim thiab kev faib lus ntawm "tuav"
1) Lub tswvyim ntawm "bar"
Nyob rau ntawm daim ntawv lithographic, ib qho zoo li strip, uas yog parallel rau cov kev taw qhia ntawm lub axis ntawm yob, yog tshwm sim los ntawm cov deformation deot, uas tseem hu ua "bar" thiab "strip".
2) Kev faib tawm ntawm "tuav"
Xim number case ntawm "bar" yuav muab faib ua ob hom: tus number case bar thiab dej bar.
Ink bar: Hauv qhov chaw luam tawm ntawm qhov teeb meem ntawm cov ntawv luam tawm, cov dot yog irregularly tsam, thiab cov ink txheej yog thickened, thiab muaj ib qho xim dub zoo ib yam (tseem hu ua "xim bar") dua li ntawm tus number case xim luam tawm ntawm tib lub sijhawm.
Dej Bar: Hauv qhov chaw luam tawm ntawm cov teeb meem sau, qhov teeb meem txo qis dua, thiab cov ink txheej txheej yog thinned, thiab muaj ib qho xim sib txawv xim sau (tseem hu ua "dawb bar") dua li ntawm tus number case xim luam tawm ntawm tib lub sijhawm.
Raws li qhov laj thawj ntawm "bar", nws tuaj yeem muab faib ua cov iav tuav, vibration tuav, cov pub tuav thiab lwm cov tuav.
Cov iav tuav: Lub precision ntawm kev sib kis ntawm cov chais, qhov chaw nyob thiab cov dej xa khoom ntawm qhov offset tshuab luam ntawv tsis txaus, ua rau cov hniav ntu hnoos lossis hniav puas tsuaj, thiab sib txuas lus tshwm sim nyob rau hauv lub meshing kis tau tus mob, ua rau cov ntaub nplua thiab duab ntawm lub nruas. Tsiv mus rau qhov "bar". Nws yog tsi ntsees rau hauv lub suab ntawm cov tuav hauv cov ntawv luam tawm yog sib npaug rau lub suab ntawm lub zog, thiab qhov tsim qhov ntom zoo li tus "ntxuav rooj".
Vibrating bar: Thaum lub tshuab luam ntawv tshuab luam ntawv ua haujlwm, nws yuav dheev dhau ntawm ib lub caij ntawm kev khiav ceev ceev. Txoj kev ua kom qhov no raug rhuav tshem lub nruas los tig ntawm qhov ceev, ua rau lub suab sway ntawm cov ntawv ywj pheej thiab tsim kom muaj "bar". Xws li lub tshuab raj kheej ua haujlwm ua haujlwm sab nrauv thiab nruab nrab, kev sib koom tes, qhov qhib thiab kaw ntawm lub nruas los ntawm kev sib tsoo ntawm txoj hlua khi ntawm txoj hlua khi los sis cov kabmob coj ntawm txhua qhov kev tivthaiv, thiab lwmyam, yuav ua rau poob siab thiab kev vibration nyob rau hauv tus txheebze slippage ntawm daim duab graphics Thiab nyob.
"Bar". Lub feature yog hais tias "bar" tshwm nyob rau hauv qhov chaw ntawm daim ntawv luam tawm thiab txoj hauj lwm yog tsau, thiab txoj hauj lwm ntawm "bar" muaj feem xyuam rau lub sij hawm thiab tsis tu ncua ntawm kev ua haujlwm ntawm kev ua haujlwm.
Cov menyuam yaus: Cov menyuam yaus yog vim muaj lub plhaub npau npo ntawm qhov tshuab luam ntawv, cov qauv siv rau hauv dej tsis tsim nyog, kev ua haujlwm ntawm cov roj hmab uas rub tawm thiab qhov sib txig ntawm txoj kev sib piv tsis zoo, ua dej, lub plhaub kheej kheej kheej kheej kheej kheej kheej kheej kheej kheej kheej kheej kheej thiab cov khau khiab lub plhaub thaum lub lag luam. Los yog, vim muaj kev tswj hwm txoj cai, txoj hauj lwm tiv tauj ncaug, uas cuam tshuam nrog kev hloov ntawm tus cwj pwm, ua ib qho "bar". Lub tshuab fais fab yog qhia tau tias ntau tus pas tuav f yog me ntsis ntxiv, qhov bar band yog qhov dav, qhov dav dav yog sib npaug ntawm qhov ntu ntawm tus cwj mem xees, qhov chaw tsis ruaj, thiab tus number case xim ua ntej thiab tom qab luam ntawv yog txawv.
Lwm cov tuav: Tej khoom tsim los ntawm cov khoom xws li cov pam pua chaw, cov txaj xaij, daim hlau, ntawv, hauv plawv, tsau dej, thiab cov txheej txheem khiav hauj lwm cuam tshuam rau hauv kev luam ntawv. Vim hais tias ntawm nws cov yam ntxwv sib txawv, qhov no tsab xov xwm yuav tsis piav ntau zog ntxiv rau qhov no.
1) Lub nraub qaum ris ntawm tus menyuam lub qhov taw ua meshing yog loj heev
1 Lub backlash tshwm sim los ntawm lub chaw kev hloov kev nyob nruab nrab yog loj heev. Lub nruas iav ntawm lub tshuab luam ntawv offset yeej yog lub hauv siab los ntawm kev siv zog. Lub iav hloov coefficient ntawm cov iav loj loj, thiab lub qhov chaw sib cais ntawm qhov chaw me me, yog li kom txo tau cov kev cuam tshuam thiab kev sib tham thaum lub sij hawm luam ntawv, thiab tuav lub ntse thiab qhov tseeb ntawm kev luam ntawv. Nyob hauv cov hauj lwm tiag tiag, tus backlash ntawm lub nruas iav mesh hloov thiab kho raws li cov ntawv luam ntawm cov ntawv sib txawv ntawm tuab. Lub thicker daim ntawv, qhov loj dua qhov chaw nruab nrab qhov kev hloov yog, qhov me me qhov txauv coefficient ntawm meshing nto ntawm lub nruas iav, thiab lub sab kis ua loj dua. Ntau dua qhov sib txawv ntawm cov kab tawm ntawm cov ntawv yob tawm, qhov loj dua tus txhauv ntawm tus tsim ua rau ntawm cov ntawv luam tawm thiab qhov tshaj tawm qhov bar. Kev Ua Ntej: Nyob rau hauv qhov tsim nyog ntawm kev ruaj ntseg ntawm kev luam ntawv, lub nrug nruab nrab ntawm peb lub vuab tsuab yuav tsum raug txo kom tsawg, thiab lub pob zeb rov qab yuav tsum tau muab qhov kom zoo kom txo tau cov "bar".
2 Sab nrawm los ntawm iav hnav yog loj heev. Tom qab lub sijhawm ua haujlwm, lub nruas iav raug hnav vim muaj tsheb lossis lwm yam khoom txawv tebchaw nyob rau hauv qhov kev sib txawv ntawm cov hniav, uas ua rau ntau lub iav meshing backlash, daim iav tsis tuaj yeem dov rau ntawm qhov ceev ceev raws li kab kev meshing, lossis cov khoom txawv teb chaws " saum hniav "ua rau lub iav ua haujlwm. Cov kev sib tham tshwm sim, ua rau txoj kev sib txhuam ntawm qhov khawb kom ua rau ua slippage, thiab cov duab ntawm daim duab ua tawm ib qho lej ribbon sib npaug zos rau lub pitch ntawm lub iav thaum lub caij ntawm lub swb, uas yog, lub iav bar. Tshuaj: Ntxiv dag zog rau kev tu vaj tse thiab kho tej khoom siv, tshem tawm thiab tshem tawm cov pav av ntawm lub zog, thiab tswj kom lub cev zoo lubrication; raws li lub iav mob hnyav, rov qab ntsuas qhov kev kho kom haum, kom nias qhov nraub qaum, thiab hloov tus tshiab tam sim ntawd. iav.
2) Cov kabmob hnav
1 Dov kabmob hnav. Tom qab cov tshuab luam ntawv tshuab luam ntawv raug siv ntev ntev, tshwj xeeb tshaj yog cov menyuam yaus tsis tuaj yeem mus rau tus menyuam, qhov kev poob siab ua rau lub siab loj loj, cov kabmob yog ib qho yooj yim hnav, thiab qhov sib txawv ntawm phau ntawv sau thiab kabmob muaj zog thiab lub tes tsho yog loosened. Lub qhov ncauj vibrates vim qhov sib txawv, thiab txoj kev sib txhuam ntawm kev sib txoos ua ib qho "bar". Qhov tshwj xeeb tshaj yog thaum lub thauj tsis zoo lossis lub lubrication tsis zoo, lub taub hau taub hau thiab lub pob ntawm lub nruas yog khov kho, thiab "bar" feem ntau yuav raug tsim nyob ze lub qhov ncauj. Tshuaj: Ib sab ntawm lub qhov ncauj ntawm cov roj hmab hauv plhaub ntog tau muab txiav mus rau hauv ib qho duab ntxoov ntxoo kom txo tau cov kev quab yuam thaum lub siab sib sau ua ke. Thaum cov menyuam yaus khau ris hnyav heev, cov kabmob yuav tsum muab kho rau lub sijhawm.
2 Duav rau cov menyuam hnav ris tsho. Dej, hauv plawv rau cov menyuam, kev tuav cov rooj tog, kev tuav cov khoom siv, cov khib nyiab los yog hnav kuj ua rau cov dej thiab khaus xaj mus rau kev loj hlob qis heev thiab khiav mus rau qhov "khiav", tshwj xeeb tshaj yog thaum cov bushing lossis kis tau ntawm cov ink roller ntoo, qhov kev co los ntawm cov meshing ntawm cov iav uas muaj feem xyuam rau qhov qub dej leveling, number case leveling thiab kis ntawm cov menyuam, uas ua rau tshwm sim ntawm "tuav".
