Imashini yerekana ibimenyetso bya Laser Marking Upgrade Guide: Kugereranya Kwerekana neza neza hagati ya Granite na Iron Iron muri Picosekond-Urwego rwo gutunganya.

?
Muburyo bunoze bwo gutunganya ibintu bya picosekond-urwego rwa lazeri yerekana ibimenyetso, shingiro, nkibice byingenzi bifasha ibikoresho, guhitamo kwayo kugena byimazeyo itunganywa ryukuri. Granite hamwe nicyuma nibikoresho bibiri bisanzwe mubikorwa byo gukora shingiro. Iyi ngingo izakora igereranya riva mubintu nkimiterere yumubiri, ihame ryo gutegera neza, hamwe namakuru afatika, atanga ishingiro ryubumenyi bwo kuzamura ibikoresho. ?
I. Itandukaniro ryumutungo wibintu: Logic Yibanze Yimikorere Yuzuye
Granite ni urutare rusanzwe rwaka, rwakozwe no korohereza hafi ya minerval nka quartz na feldspar imbere. Irangwa nuburyo bwuzuye kandi bukomeye. Ubucucike bwabwo buri hagati ya 2.7 na 3.1g / cm³, kandi coefficente yo kwaguka kwubushyuhe ni muke cyane, hafi (4-8) × 10⁻⁶ / ℃, ishobora kurwanya neza ingaruka zimihindagurikire yubushyuhe ku bikoresho bifatika. Byongeye kandi, microstructure idasanzwe ya granite iyiha imikorere myiza yo kumeneka, ikabasha kwinjiza vuba imbaraga zinyeganyeza zo hanze no kugabanya kwivanga kwinyeganyeza kubikorwa byukuri. ?
Ibyuma, nkibikoresho gakondo byinganda, bifite ubucucike bwa 7.86g / cm³, ugereranije imbaraga zo gukanda, ariko birashyushye
Umubare wo kwaguka (hafi 12 × 10⁻⁶ / ℃) ni inshuro 1.5-3 za granite. Byongeye kandi, hari flake grafite yubatswe imbere mucyuma. Mugihe cyo gukoresha igihe kirekire, izi nzego zirashobora gutuma umuntu ahangayikishwa cyane, bikagira ingaruka kumitekerereze yibintu hanyuma bigatera kugabanuka neza. ?

Ii. Uburyo bwa Attenuation Mechanism muri Picosekond-Urwego rwo Kumashini
Urwego rwa Picosecond urwego rwa laser rufite ibisabwa cyane kugirango ibidukikije bihamye. Ihinduka rito ryibikoresho fatizo bizashyirwa mubisubizo byo gutunganya. Imihindagurikire yubushyuhe, kunyeganyezwa biterwa nigikorwa cyibikoresho, umunaniro munsi yumutwaro muremure, nibindi, nibintu byose byingenzi biganisha kumurongo. ?
Iyo ubushyuhe buhindutse, ingano ya granite ihinduka gato bitewe na coefficient yayo yo kwaguka kwinshi. Ikigereranyo kinini cyo kwagura ubushyuhe bwumuriro wibyuma bizatera ishingiro kugirango habeho guhindura ibintu bigoye kubimenya n'amaso. Ihinduka rizagira ingaruka ku buryo butaziguye inzira ya laser optique kandi itume umwanya uhinduka. Kubijyanye no kunyeganyega, hejuru cyane yo kuranga granite irashobora guhuza 100Hz kunyeganyega mumasegonda 0.12, mugihe icyuma gisaba amasegonda 0.9. Mugihe cyumuvuduko mwinshi cyane, gutunganya neza ibikoresho bifite ibyuma bikozwe mubyuma bikunda guhindagurika. ?
Iii. Kugereranya Ibyatanzwe Byuzuye
Ukurikije ibizamini byinzego zumwuga, mugihe cyo gukomeza amasaha 8 ya picosekond laser yerekana ibimenyetso, kwiyegereza XY-axis ihagaze neza yibikoresho bifite base ya granite iri muri ± 0.5μm. Kwiyerekana neza kubikoresho fatizo byuma bigera kuri mm 3μm, hamwe nibitandukaniro rikomeye. Mubidukikije byigana hamwe nubushyuhe bwa 5 ℃, ikosa ryo guhindura ubushyuhe bwibikoresho bya granite ni + 0.8 mm gusa, mugihe ibyo bikoresho byuma bikozwe mucyuma bingana na + 12μm. ?
Byongeye kandi, ukurikije imikoreshereze yigihe kirekire, igipimo cyo guca imanza za granite ni 0,03% gusa, mugihe igipimo cyo guca imanza zicyuma gikozwe mucyuma kiri hejuru ya 0.5% kubera ibibazo byimiterere ihamye. Aya makuru yerekana neza ko mubisabwa-bisobanutse neza byo gutunganya picosekond-urwego, inyungu ihamye ya granite base irahambaye. ?
Iv. Kuzamura ibyifuzo hamwe nibikorwa bifatika
Ku mishinga ikurikirana neza gutunganya neza, kuzamura ibyuma bikozwe mucyuma cya granite nuburyo bwiza bwo kuzamura imikorere yibikoresho. Mugihe cyo kuzamura, hagomba kwitonderwa uburyo bwo gutunganya neza granite kugirango tumenye neza ko uburinganire bwujuje ibyangombwa bisabwa. Muri icyo gihe, ufatanije n’ibikoresho bifasha nka sisitemu yo guhindagura ikirere ya flotation yo mu kirere, imikorere yo kurwanya vibrasiya y’ibikoresho irashobora kurushaho kunozwa. ?
Kugeza ubu, mu nganda nko gukora chip ya semiconductor no gutunganya neza ibikoresho bya optique, imashini zerekana ibimenyetso bya laser hamwe na base ya granite zarakoreshejwe cyane, bizamura umusaruro wibicuruzwa no gukora neza. Kurugero, nyuma yumushinga runaka wibikoresho bya optique yazamuye ibikoresho byuma bikozwe mucyuma, igipimo cyujuje ubuziranenge cyibicuruzwa cyavuye kuri 82% kigera kuri 97%, kandi umusaruro wiyongereye cyane. ?
Mu gusoza, mukuzamura shingiro ryimashini ya lazeri ya picosekond, granite, hamwe nubushuhe buhebuje bwumuriro, imikorere ya damping yo hejuru hamwe nubushobozi bwigihe kirekire bwo kugumana neza, byahindutse amahitamo meza kuruta icyuma. Ibigo birashobora guhitamo neza ibikoresho fatizo bishingiye kubyo basabwa gutunganya ningengo yimari kugirango bagere ku ntera yuzuye yimikorere yibikoresho.
