Nabonye raporo nkiyi kera cyane: abahanga baturutse mubudage, mubuyapani no mubindi bihugu bamaranye imyaka 5 kandi bakoresha hafi miliyoni 10 yuan kugirango bakore umupira wakozwe mubikoresho byiza bya silicon-28. Uyu mupira wa kg 1 wuzuye usaba Ultra-precision gutunganya, gusya no gusya, gupima neza (sphericity, roughness and quality), birashobora kuvugwa ko ari umupira uzengurutse isi.
Reka tumenye inzira ya ultra-precision polishing.
01 Itandukaniro riri hagati yo gusya no gusya
Gusya: Ukoresheje ibice byangiza bisize cyangwa bikanda ku gikoresho cyo gusya, ubuso burangizwa nigikorwa cyo kugereranya igikoresho cyo gusya hamwe nakazi kakozwe mukibazo runaka. Gusya birashobora gukoreshwa mugutunganya ibyuma bitandukanye nibikoresho bitari ibyuma. Imiterere yubuso yatunganijwe irimo indege, imbere ninyuma ya silindrike hamwe na conique hejuru, convex hamwe na spherical serefegitura, insinga, amenyo yandi hamwe nibindi bisobanuro. Gutunganya neza birashobora kugera kuri IT5 ~ IT1, kandi ububobere bwo hejuru bushobora kugera kuri Ra0.63 ~ 0.01μm.
Gusiga: Uburyo bwo gutunganya bugabanya ubuso bwibikorwa byakazi ukoresheje imashini, imiti cyangwa amashanyarazi kugirango ubone ubuso bwiza kandi bworoshye.
Itandukaniro nyamukuru hagati yibi byombi ni uko kurangiza hejuru kugerwaho no gusya birenze ibyo gusya, kandi uburyo bwa chimique cyangwa electrochemicique burashobora gukoreshwa, mugihe gusya ahanini bikoresha uburyo bwa mashini gusa, kandi ingano yimbuto zikoreshwa ni ntoya kuruta iyakoreshejwe kurisha. Nukuvuga, ingano yingingo nini.
02 Ikoranabuhanga rya ultra-precision tekinoroji
Ultra-precision polishing nubugingo bwinganda zigezweho
Inshingano ya tekinoroji ya ultra-precision munganda zigezweho za elegitoroniki ntabwo ari ugusibanganya ibikoresho bitandukanye gusa, ahubwo no gusibanganya ibikoresho byinshi, kuburyo wafer ya silicon ya kilometero kare imwe ishobora gukora ibihumbi icumi kugeza kuri VLSI igizwe na miriyoni transistors. Kurugero, mudasobwa yahimbwe nabantu yahindutse kuva kuri toni mirongo igera kuri garama amagana muri iki gihe, idashobora kugerwaho hatabayeho gukabya gukabya.
Dufashe urugero rwa wafer nkurugero, guswera nintambwe yanyuma yibikorwa byose, ikigamijwe ni ugutezimbere utunenge duto twasizwe nuburyo bwabanjirije gutunganya wafer kugirango tubone parallel nziza. Uyu munsi urwego rwa optoelectronic urwego rwinganda rusaba byinshi kandi bisobanutse neza kuburinganire kubintu bya optoelectronic substrate ibikoresho nka safiro na silikoni imwe ya kirisiti, bigeze kurwego rwa nanometero. Ibi bivuze ko inzira yo gusya nayo yinjiye murwego rwa ultra-precision ya nanometero.
Ukuntu inzira ya ultra-precision polishing ari ingenzi mubikorwa bigezweho, imirima yabyo irashobora gusobanura mu buryo butaziguye ikibazo, harimo gukora inganda zuzuzanya, ibikoresho byubuvuzi, ibice byimodoka, ibikoresho bya digitale, ibishushanyo mbonera hamwe nindege.
Ubuhanga bwo hejuru bwo gusya bukoreshwa neza gusa nibihugu bike nka Amerika n'Ubuyapani
Igikoresho cyibanze cyimashini isya ni "gusya". Ultra-precision polishing ifite ibyangombwa bisabwa cyane kubigize ibikoresho nibisabwa bya tekinike yo gusya disiki mumashini isya. Ubu bwoko bwa disiki yicyuma ikomatanyirijwe mubikoresho bidasanzwe ntigomba kuba yujuje gusa nano-urwego rwukuri rwo gukora byikora, ariko kandi ifite na coefficient yo kwagura ubushyuhe.
Iyo imashini isya ikora ku muvuduko mwinshi, niba kwaguka k'ubushyuhe bitera guhindagurika k'ubushyuhe bwa disiki yo gusya, uburinganire n'ubwuzuzanye bwa substrate ntibishobora kwizerwa. Kandi ubu bwoko bwikibazo cyo guhindura ibintu bidashobora kwemererwa kubaho ntabwo ari milimetero nkeya cyangwa microne nkeya, ahubwo ni nanometero nkeya.
Kugeza ubu, uburyo mpuzamahanga bwo gutunganya ibintu nka Amerika ndetse n’Ubuyapani birashobora kuba byujuje ibyangombwa bisabwa neza by’ibikoresho fatizo bya santimetero 60 (bifite ubunini buhebuje). Hashingiwe kuri ibi, bamenye ikorana buhanga ryibikorwa bya poli ultra-precision polishing kandi basobanukiwe neza gahunda yibikorwa byisoko ryisi. . Mubyukuri, kumenya iryo koranabuhanga bigenzura kandi iterambere ryinganda zikora ibikoresho bya elegitoroniki.
Guhangana nikibazo gikomeye cya tekiniki, mubijyanye na poli ya ultra-precision, igihugu cyanjye gishobora gukora ubushakashatsi bwonyine.
Ni uruhe rwego rw'ikoranabuhanga rikoresha amashanyarazi mu Bushinwa?
Mubyukuri, mubijyanye na ultra-precision polishing, Ubushinwa ntibufite ibyagezweho.
Mu mwaka wa 2011, “Cerium Oxide Microsphere Particle Size Standard Standard Standard and Technology Technology” yateguwe n'itsinda rya Dr. Wang Qi wo mu kigo cy'igihugu gishinzwe ubumenyi bwa Nanoscale mu Ishuri Rikuru ry'Ubushinwa ryatsindiye igihembo cya mbere cy'inganda zikomoka kuri peteroli n'inganda mu Bushinwa. Igihembo cya Federasiyo Yivumbuwe, hamwe nubunini bwa nanoscale ingano yububiko Ibikoresho Byabonye uruhushya rwo gupima ibikoresho byigihugu hamwe nicyemezo cyambere cyibintu byo mu rwego rwa mbere. Ingaruka yikigereranyo cyibikorwa bya ultra-precision yibikoresho bishya bya cerium oxyde yarenze ibikoresho gakondo byamahanga mumahanga umwe, byuzuza icyuho muriki gice.
Ariko Dr. Wang Qi yagize ati: “Ibi ntibisobanura ko twazamutse hejuru y'uyu murima. Mubikorwa rusange, hariho gusya gusa ariko nta mashini ya ultra-precision yamashanyarazi. Byinshi, turimo kugurisha ibikoresho gusa. ”
Muri 2019, itsinda ry’ubushakashatsi bwa Porofeseri Yuan Julong wo muri kaminuza y’ikoranabuhanga ya Zhejiang ryashyizeho ikoranabuhanga ry’imashini itunganya imashini. Urukurikirane rw'imashini zo gusya zakozwe zakozwe cyane na Yuhuan CNC Machine Tool Co., Ltd, kandi zamenyekanye nka iPhone4 na iPad3 ikirahure na Apple. Ibikoresho byonyine byogeza isi neza kubikoresho bya panne na aluminium alloy backplane polishing, imashini zirenga 1.700 zikoreshwa mugukora cyane ibyapa bya Apple bya iPhone na iPad.
Ubwiza bwo gutunganya imashini buri muribi. Kugirango ukurikirane imigabane ninyungu, ugomba kugerageza uko ushoboye kugirango ufate abandi, kandi umuyobozi wikoranabuhanga azahora atezimbere kandi atezimbere, arusheho kunonosorwa, guhora arushanwa no gufata, no guteza imbere iterambere rikomeye rya ikoranabuhanga rya muntu.
