Kuyeretsa laser ya mafakitale ndi njira yoponyera kuwala kwa laser pamalo olimba kuti ayeretsedwe ndi laser ndikuchotsa chinthu chosafunikira. Popeza mtengo wa gwero la fiber laser watsika kwambiri m'zaka zingapo zapitazi, oyeretsa laser—opangidwa kuti athandize ogwiritsa ntchito kuyeretsa ndi laser bwino—akwaniritsa zosowa zambiri zamsika komanso zomwe zingagwiritsidwe ntchito, monga kuyeretsa njira zopangira jakisoni, kuchotsa mafilimu opyapyala kapena malo monga mafuta, ndi mafuta, ndi zina zambiri.

Kodi Kuyeretsa kwa Laser N'chiyani?
Mwachikhalidwe, kuti muchotse dzimbiri, utoto, okusayidi, ndi zinthu zina zodetsa pamwamba pa chitsulo, kuyeretsa kwa makina, kuyeretsa kwa mankhwala, kapena kuyeretsa kwa ultrasound kungagwiritsidwe ntchito. Kugwiritsa ntchito njira izi ndi kochepa kwambiri pankhani ya chilengedwe komanso kulondola kwambiri.
Njira Yoyeretsera ndi Laser.
M'zaka za m'ma 80, asayansi adapeza kuti powunikira pamwamba pa chitsulo chomwe chazizidwa ndi mphamvu ya laser yolimba kwambiri, chinthu choyatsidwacho chimakumana ndi zovuta zambiri zakuthupi ndi zamankhwala monga kugwedezeka, kusungunuka, kusungunuka, ndi kuyaka. Zotsatira zake, zodetsa zimachotsedwa pamwamba pa chinthucho. Njira yosavuta koma yothandiza yoyeretsera iyi ndi kuyeretsa ndi laser, komwe pang'onopang'ono kwalowa m'malo mwa njira zachikhalidwe zoyeretsera m'magawo ambiri ndi zabwino zake zambiri, kusonyeza chiyembekezo chachikulu chamtsogolo.
Kodi Otsuka a Laser Amagwira Ntchito Bwanji?
Makina Oyeretsera a Laser
Zotsukira za laser zimapangidwa ndi magawo anayi:gwero la laser ya fiber (yosalekeza kapena ya pulse laser), bolodi lowongolera, mfuti ya laser yonyamula m'manja, ndi choziziritsira madzi chotentha nthawi zonseBolodi lowongolera kuyeretsa ndi laser limagwira ntchito ngati ubongo wa makina onse ndipo limapereka dongosolo kwa jenereta ya fiber laser ndi mfuti ya laser yonyamula m'manja.
Jenereta ya laser ya ulusi imapanga kuwala kwa laser kokhala ndi mphamvu zambiri komwe kumadutsa mu conduction medium Fiber kupita ku mfuti ya laser yogwiritsidwa ntchito m'manja. Galimoto yowunikira, kaya ya uniaxial kapena biaxial, yomwe imasonkhana mkati mwa mfuti ya laser imawonetsa mphamvu ya kuwala ku dothi la workpiece. Ndi kuphatikiza kwa zochita zakuthupi ndi zamankhwala, dzimbiri, utoto, dothi lamafuta, wosanjikiza wokutira, ndi zina zodetsa zimachotsedwa mosavuta.
Tiyeni tikambirane mwatsatanetsatane za njira imeneyi. Mavuto omwe amadza chifukwa chogwiritsa ntchitokugwedezeka kwa kugunda kwa laser, kufalikira kwa kutenthaza tinthu tomwe tawotchedwa ndi radiation,kuwonongeka kwa maselokusintha kwa gawo, kapenazochita zawo pamodzikuti athetse mphamvu yomangirira pakati pa dothi ndi pamwamba pa workpiece. Zipangizo zomwe zikufunika kuchotsedwa (pamwamba pake) zimatenthedwa mofulumira poyamwa mphamvu ya kuwala kwa laser ndipo zimakwaniritsa zofunikira za sublimation kotero kuti dothi lochokera pamwamba lizimiririka kuti likwaniritse zotsatira za kuyeretsa. Chifukwa cha zimenezi, pamwamba pa substrate simatenga mphamvu iliyonse, kapena mphamvu yochepa kwambiri, kuwala kwa fiber laser sikungawononge konse.
Dziwani zambiri za Kapangidwe ndi Mfundo ya Chotsukira Laser Chogwiritsidwa Ntchito Pamanja
Machitidwe Atatu a Kuyeretsa kwa Laser
1. Kupondereza
Kapangidwe ka mankhwala a zinthu zoyambira ndi zodetsa ndi kosiyana, komanso kuchuluka kwa kuyamwa kwa laser. Gawo loyambira limawonetsa kuwala kwa laser kopitilira 95% popanda kuwonongeka, pomwe chodetsacho chimayamwa mphamvu yambiri ya laser ndikufikira kutentha kwa sublimation.

2. Kukula kwa Kutentha
Tinthu toipitsa mpweya timayamwa mphamvu ya kutentha ndipo timakula mofulumira mpaka kufika pophulika. Kuphulikako kumagonjetsa mphamvu yolumikizana (mphamvu yokopa pakati pa zinthu zosiyanasiyana), motero tinthu toipitsa mpweya timachotsedwa pamwamba pa chitsulocho. Chifukwa nthawi yowunikira ndi laser ndi yochepa kwambiri, imatha kupanga nthawi yomweyo mphamvu yolimbana ndi kuphulika, yokwanira kupereka kufulumira kokwanira kwa tinthu tating'onoting'ono kuti tisunthire kuchokera ku kulumikiza kwa zinthu zoyambira.

3. Kugwedezeka kwa Kugunda kwa Laser
Kuchuluka kwa kugunda kwa kuwala kwa laser ndi kochepa, kotero kugwira ntchito mobwerezabwereza kwa kugunda kudzapangitsa kugwedezeka kwa ultrasound kuti kutsuke workpiece, ndipo mafunde ogwedezeka adzaswa tinthu toipitsa.

Ubwino wa Makina Oyeretsera a Fiber Laser
Popeza kuyeretsa pogwiritsa ntchito laser sikufuna mankhwala osungunulira kapena zinthu zina zogwiritsidwa ntchito, ndikosamala chilengedwe, ndikotetezeka kugwiritsa ntchito, ndipo kuli ndi zabwino zambiri:
✔Ufa wa solider ndi zinyalala zomwe zimachotsedwa pambuyo poyeretsa, zimakhala zochepa, ndipo zimakhala zosavuta kusonkhanitsa ndikubwezeretsanso.
✔Utsi ndi phulusa zomwe zimapangidwa ndi fiber laser n'zosavuta kutulutsa ndi chotsukira utsi, ndipo sizovuta pa thanzi la anthu.
✔Kuyeretsa kosakhudzana ndi kukhudzana, palibe zotsalira, palibe kuipitsidwa kwachiwiri
✔Kuyeretsa chinthu chomwe chili pamalopo (dzimbiri, mafuta, utoto, zokutira), sikungawononge pamwamba pa nthaka.
✔Magetsi ndiye okhawo omwe amagwiritsidwa ntchito, otsika mtengo wogwiritsa ntchito, komanso okonza
✔Yoyenera malo ovuta kufikako komanso kapangidwe ka zinthu zovuta kupanga
✔Loboti yoyeretsa yokha ndi laser yokha, m'malo mwake ndi yopangidwa ndi zinthu zopangidwa ndi laser.
Pochotsa zinthu zodetsa monga dzimbiri, nkhungu, utoto, zilembo zamapepala, ma polima, pulasitiki, kapena zinthu zina zilizonse pamwamba, njira zachikhalidwe - kuphulika kwa media ndi kupukutira mankhwala - zimafuna kusamalidwa mwapadera ndikutayidwa kwa media ndipo nthawi zina zimakhala zoopsa kwambiri ku chilengedwe ndi ogwiritsa ntchito. Gome ili pansipa likuwonetsa kusiyana pakati pa kuyeretsa kwa laser ndi njira zina zotsukira mafakitale.

Mafunso Ofunsidwa Kawirikawiri
Inde, ndi yotetezeka kwathunthu. Chinsinsi chake chili pa kuchuluka kosiyana kwa kuyamwa kwa laser: maziko ake amawonetsa mphamvu yoposa 95% ya laser, zomwe zimayamwa kutentha pang'ono kapena kosayamwa. Zoipitsa (dzimbiri, utoto) zimayamwa mphamvu zambiri m'malo mwake. Mothandizidwa ndi kugunda kwa mtima kolondola, njirayi imangoyang'ana zinthu zosafunikira, kupewa kuwonongeka kulikonse kwa kapangidwe ka substrate kapena khalidwe la pamwamba.
Imasamalira bwino mitundu yosiyanasiyana ya zinthu zodetsa mafakitale.
- Dzimbiri, ma oxide, ndi dzimbiri pamwamba pa zitsulo.
- Utoto, zokutira, ndi mafilimu opyapyala ochokera ku zinthu zogwirira ntchito.
- Mafuta, mafuta, ndi madontho mu njira zopangira jakisoni.
- Zotsalira za welding ndi ma burrs ang'onoang'ono asanayambe/atamaliza welding.
- Sizimangokhala pa zitsulo zokha—zimagwiranso ntchito pa zinthu zina zomwe si zachitsulo kuti ziwononge kuwala.
Ndi yotetezeka kwambiri ku chilengedwe kuposa kuyeretsa ndi mankhwala kapena makina.
- Palibe mankhwala osungunulira (omwe amapewa kuipitsa nthaka/madzi) kapena zinthu zina zowononga (omwe amachepetsa zinyalala).
- Zinyalala zimakhala ufa wochepa kapena utsi wochepa, womwe ndi wosavuta kusonkhanitsa kudzera mu zotulutsa utsi.
- Imagwiritsa ntchito magetsi okha—siifunikira kutaya zinyalala zoopsa, ikutsatira miyezo yokhwima yokhudza chilengedwe m'mafakitale.
