Kev txhim kho me me hauv cov cuab yeej luam ntawv gravure tuaj yeem yooj yim daws qhov teeb meem kev sib cuag hauv kev tsim RFID cov cim npe hluav taws xob !!
Nrog rau qhov tshwm sim ntawm lub sijhawm mobile Internet tau tswj hwm los ntawm 5G thev naus laus zis, Is Taws Nem ntawm Txhua Yam thiab kev paub thoob plaws ntiaj teb tau maj mam dhau los ua qhov tseeb. Raws li ib qho tseem ceeb txhais tau tias rau Is Taws Nem ntawm Yam (IoT) kom pom lub ntiaj teb sab nraud, RFID cov cim npe hluav taws xob, tshwj xeeb tshaj yog ultra- cov cim npe RFID siab, yuav siv dav. Hauv tsab xov xwm no, raws li kev paub ntau lawm, tus sau qhia txog daim ntawv thov ntawm gravure luam ntawv hauv kev tsim RFID cov cim npe hluav taws xob thiab tawm tswv yim qee qhov kev daws teeb meem los txhim kho kev luam ntawv zoo rau cov neeg nyeem ntawv siv.
Technical nta ntawm RFID Electronic Tags
RFID cov cim npe hluav taws xob yog cov cim npe uas siv cov cuab yeej tsis siv neeg tsis siv neeg txheeb xyuas los txheeb xyuas cov khoom lag luam thiab tau txais cov ntaub ntawv cuam tshuam los ntawm cov xov tooj cua zaus, tsis tas yuav muaj kev cuam tshuam rau tib neeg thaum lub sijhawm lees paub. Raws li lub wireless version ntawm barcodes, RFID hluav taws xob cim npe muaj qhov zoo uas cov barcodes tsis muaj, suav nrog kev ua dej tsis zoo, hlau nplaum- tiv taus, siab - kub- resistant, ntev hauv kev pab cuam lub neej, muaj peev xwm ntev - nyeem ntawv nyob deb, tso cai rau cov ntaub ntawv encryption, muaj peev xwm khaws cov ntaub ntawv loj dua, thiab hloov kho cov ntaub ntawv hloov kho yooj yim. Txoj kev encoding, khaws cia, thiab kev nyeem ntawv / sau ntawv ntawm RFID cov cim hluav taws xob txawv ntawm cov cim cim (xws li barcodes) lossis phau ntawv cim npe. Cov ntaub ntawv encoded yog khaws cia rau hauv kev sib koom ua ke hauv kev nyeem - nkaus xwb lossis nyeem / sau hom ntawv. Tshwj xeeb, kev nyeem ntawv thiab sau ntawv tau ua tiav los ntawm kev xa xov hluav taws xob wireless, raws li pom hauv daim duab 1.
Zuag qhia tag nrho, cov yam ntxwv tseem ceeb ntawm RFID cov cim npe hluav taws xob yog: lawv tuaj yeem txheeb xyuas tus kheej, cov khoom tshwj xeeb, tsis zoo li cov barcodes uas tuaj yeem txheeb xyuas ib pawg ntawm cov khoom; lawv tuaj yeem nyeem ntau yam khoom ib txhij, qhov barcodes yuav tsum tau nyeem ib los ntawm ib qho; lawv tuaj yeem khaws ntau cov ntaub ntawv; thiab los ntawm kev siv xov tooj cua zaus, cov ntaub ntawv tuaj yeem nyeem los ntawm cov ntaub ntawv sab nraud, thaum cov barcodes xav tau lasers lossis infrared los nyeem cov ntaub ntawv los ntawm cov ntaub ntawv saum npoo.
Daim duab 1 Schematic daim duab ntawm lub hauv paus ntsiab lus ntawm kev ua hauj lwm ntawm RFID hluav taws xob tagCommon manufacturing processes of RFID electronic tags Muaj peb lub ntsiab kev tsim khoom rau RFID electronic tags: tooj liab hlau hlawv txheej txheem, hlau etching txheej txheem, thiab luam ntawv txheej txheem. Ntawm lawv, cov txheej txheem luam ntawv feem ntau yog siv cov tshuab luam ntawv tshuaj ntsuam (raws li qhia hauv daim duab 2). Vim muaj cov kev txwv ntawm conductivity thiab conductive mechanism ntawm conductive paste, tsuas yog siab -nyiaj- cov ntsiab lus conductive silver paste thiab qis-mesh- suav npo mesh tuaj yeem siv tau. Ntxiv mus, cuam tshuam los ntawm ntau yam xws li number case viscosity, ductility, fluidity, squeegee pressure, screen tension, and mesh interference, the printed RFID electronic tag wiring structure is prone to issues such as deformation, rough edges, short circuits, so, and a significant difference between real radiation efficiency and theoretical radiation efficiency, as displayed in F3.

Tshooj 3 ntawm RFID daim ntawv pov thawj
RFID RFID cov khoom siv普及应用超高频RFID电子标签的主要瓶颈是标签的价格, 尺寸和环境适应性.铝箔蚀刻法制作日线的过程包括金属贴合，光阻印刷，金属蚀刻等，流程较为朐偏高且不环保.其中，在印刷日线油墨方面，根据成分不同，包括银浆，与浆，与浆。等,以金属浆料印刷的日线效果最好.然而,目前铝,铜金属浆需高温脱氧烧结导电性, 使得日线底材受到一定限制, 而传统碳浆导电性未达日线应用的甶阻要日线的制程繁琐，价格昂贵，导电性能会因弯折而降低，使得目前在市场上利刼年。 RFID RFID 日线的方式仍无法大规模生产并无法取代目前的铝蚀刻日线.而采用RFI D电子标签导电浆料制作日线，其制程环保，简单且无污染，价格便宜且质量载种无线日线的印制，在市场上无论从性能方面，还是价格方面来说，都具备十足的竞。
凹版印刷在RFID 电子标签制作中的应用
由于导电浆料具备导电性能高, 兼了性强, 性价比高等特点, 越来越多的厂家采用石墨烯浆料印制RFID标签.RFID, RFID, RFID电子标签的生产制造通常采用凹版印刷来完成.在印刷过程中,石墨烯浆料被填充到凹版滚筒的凹槽内，凹版滚筒表面多余的石墨烯浆料用刮刀刮掉, 凹槽内的石墨烯浆料印刷至基材上.为适用于各种印刷场合, 如不同粗糙度或不同型号的凹版滚筒,不同结构的石墨烯日线等，需要调整刮刀与凹版滚筒的接触角度, 接触压力等参数, 以防止所印制的石墨烯RFID电子标签日线出现结构变形, 边界粗糙, 短路, 断路等问题.Under Cov xwm txheej ib txwm muaj, nyob rau hauv cov khoom siv gravure uas twb muaj lawm, tom qab kho tus kws kho mob lub kaum sab xis, txoj hauj lwm ntawm tus kws kho mob hniav raug kho thaum lub sij hawm luam ntawv thiab hloov tsis tau. Yog tias qhov chaw ua haujlwm ntawm tus kws kho mob tau hloov kho, nws yuav ua rau muaj kev sib cuag ntau dhau los yog tsis txaus siab nrog lub tog raj kheej gravure, lossis, vim qhov siab precision haum ntawm tus kws kho hniav thiab lub tog raj kheej gravure, tej zaum yuav muaj teeb meem qhov twg lawv tsis sib cuag. Tsis tas li ntawd, rau gravure thooj voos kheej kheej nrog tsawg roundness precision, tus kws kho mob hniav yuav tsis tas li hu rau saum npoo ntawm gravure lub tog raj kheej, ua rau nws tsis yooj yim sua kom huv si tshem tawm cov graphene ntau dhau. Tsis tas li ntawd, yog tias lub tshuab luam ntawv ua haujlwm tsis zoo thiab lub tog raj kheej gravure shakes, nws tuaj yeem ua rau muaj kev cuam tshuam rau tus kws kho mob hniav, ua rau tus kws kho hniav thiab nws cov txheej txheem cuam tshuam los cuam tshuam kev ntxhov siab, ua rau tus kws kho hniav puas tsuaj lossis nws cov txheej txheem sib txuas, uas ua rau cov tshuaj txhuam hniav tshem tawm lub peev xwm ntawm tus kws kho mob hniav. Hais txog kev sib cuag ntawm tus kws kho mob hniav thiab lub tog raj kheej gravure, cov khoom siv gravure uas twb muaj lawm tsis tuaj yeem tswj tau. Feem ntau, nws yog preset raws li kev paub dhau los, ua rau cov neeg tsis zoo thiab yoog raws cov khoom sib txawv. Qhov no tiv thaiv kev teeb tsa tus kws kho mob kom haum raws li qhov tseeb ntawm cov khoom, yog li cuam tshuam rau kev luam ntawv zoo ntawm graphene RFID cov ntawv xov tooj hluav taws xob.Yuav daws qhov teeb meem no, tus sau tau txhim kho cov tshuab luam ntawv gravure, tso cai rau kev hloov pauv ntawm gravure lub tog raj kheej, tus kws kho mob hniav, cov kab hloov kho, lub kaum sab xis hloov kho, cov khoom hloov siab, thiab Floating Cheebtsam, raws li qhia hauv 4.
Daim duab 4 Schematic daim duab ntawm cov khoom muaj feem xyuam rau lub gravure printing ntaus ntawv
Cov txheej txheem tshwj xeeb yog raws li hauv qab no: qhov kev hloov kho yog txuas nrog tus kws kho mob hniav thiab txav mus rau linearly raws radial kev taw qhia ntawm lub tog raj kheej gravure, ua rau tus kws kho hniav tuaj yeem txav nrog cov khoom txav mus los; lub kaum sab xis hloov kho txuas txuas tus kws kho hniav thiab cov kab hloov kho, tso cai rau tus kws kho mob hniav thiab cov kab hloov kho kom tig raws li txhawm rau kho lub kaum sab xis ntawm tus kws kho mob hniav thiab lub tog raj kheej gravure; lub rotating ib feem yog txuas nrog tus kws kho mob hniav thiab cov linear hloov cov khoom los ntawm ib tug movable seem, enabling tus kws kho mob hniav thiab cov linear kho kom haum yuav txav radially txheeb ze rau lub gravure lub tog raj kheej.
Qhov kev daws teeb meem no tuaj yeem kho lub kaum sab xis ntawm tus kws kho mob thiab lub tog raj kheej gravure, nrog rau kev kho thiab ntsuas qhov sib cuag ntawm lawv, kom ntseeg tau tias cov graphene ntau dhau ntawm lub tog raj kheej gravure tau tawg tag nrho thaum muab tshuaj txhuam hauv cov grooves luam tawm mus rau hauv substrate. RFID hluav taws xob cov ntawv luam tawm siv lub tshuab luam ntawv gravure no nthuav tawm cov npoo du, tsis muaj serrations, thiab kev siv hluav taws xob tiag tiag raws li kev siv hluav taws xob theoretical, daws cov teeb meem tau zoo thaum tsim RFID hluav taws xob cim npe los ntawm kev tshuaj ntsuam luam ntawv, raws li pom hauv daim duab 5.
Daim duab 5 Kev nthuav dav hauv zos ntawm tus neeg xyuas pib ntawm intaglio- luam tawm RFID hluav taws xob tagCov tshuab luam ntawv intaglio tuaj yeem siv rau ntau yam kev luam ntawv. Nws tiv thaiv cov txheej txheem deformation, ntxhib npoo, thiab luv luv Circuit Court lossis tawg hauv cov ntawv luam tawm graphene RFID tag antennas, kom ntseeg tau tias luam ntawv zoo ntawm RFID hluav taws xob cim npe tsim los ntawm intaglio luam ntawv. Qhov no ua tiav kev ua haujlwm siab thiab ua haujlwm tau zoo, daws cov teeb meem kev sib tw uas muaj nyob rau hauv RFID tag luam ntawv.
