Dab tsi yog mesh off-contact ntawm flat screen printing tshuab?

Flat screen printing yog ib txoj kev luam ntawv dav siv hauv textile thiab electronics industries. Cov txheej txheem suav nrog kev siv tus cwj mem mus rau qhov chaw tiaj tus los ntawm lub vijtsam mesh, uas yog siv los hloov cov duab mus rau substrate. Txhawm rau kom ua tiav cov txiaj ntsig luam ntawv raug thiab zoo ib yam, lub vijtsam yuav tsum tau tuav ntawm qhov kev ncua deb ntawm lub substrate, thiab txhua qhov kev vibrations lossis kev hloov pauv hauv siab yuav tsum raug txo kom tsawg. Qhov no yog qhov uas cov khoom siv off-grid, los yog hu ua off-contact device, los rau hauv kev ua si.

Cov khoom siv off-grid yog ntsia rau ntawm lub tshuab luam ntawv tiaj tus thiab yog lub luag haujlwm tswj xyuas qhov sib txawv tsis tu ncua lossis qhov nrug ntawm qhov screen thiab substrate thaum luam ntawv. Cov cuab yeej muaj ob yam khoom: lub caij nplooj ntoos hlav-loaded mechanism thiab ib qho kev hloov kho pob qhov rooj. Lub caij nplooj ntoos hlav-loaded mechanism tswj tus nqi ntawm lub siab siv rau lub vijtsam, thaum lub pob qhov hloov kho yog siv los tswj qhov sib txawv ntawm qhov screen thiab substrate.

Thaum lub sij hawm luam ntawv, lub vijtsam yog qis dua mus rau lub substrate kom txog thaum nws ua rau kev sib cuag. Thaum lub vijtsam kov lub substrate, lub caij nplooj ntoos hlav-loaded mechanism kicks hauv thiab ncua lub vijtsam me ntsis saum lub substrate. Qhov kev ncua no tiv thaiv lub vijtsam los ntawm kev rub lossis smudging tus number case ntawm lub substrate, uas tuaj yeem cuam tshuam qhov zoo ntawm cov ntawv kawg. Tus nqi ntawm lub siab siv los ntawm lub caij nplooj ntoos hlav tuaj yeem hloov kho kom haum raws li qhov xav tau ntawm cov substrate thiab tus cwj mem siv.

Lub pob qhov hloov kho ntawm lub tshuab hluav taws xob tawm yog siv los tswj qhov sib txawv ntawm qhov screen thiab substrate. Qhov sib txawv no yog hu ua qhov kev sib cuag deb thiab tuaj yeem hloov kho nyob ntawm qhov tuab ntawm lub substrate thiab viscosity ntawm tus number case siv. Qhov kev sib cuag me me yog qhov zoo dua rau cov substrates nyias, thaum qhov kev ncua deb dua yog nyiam dua rau cov substrates tuab.

Hauv kev xaus, cov khoom siv off-daim phiaj yog ib qho tseem ceeb ntawm lub tshuab luam ntawv tiaj tus uas ua kom cov ntawv luam tawm raug thiab zoo ib yam. Nws tuav qhov sib txawv tsis tu ncua ntawm qhov screen thiab substrate, uas tiv thaiv smudging thiab dragging ntawm number case. Nws cov yam ntxwv kho tau ua rau nws muaj ntau yam thiab haum rau siv nrog ntau yam substrates thiab inks.
