Ruzivo rwekutanga rwe tekinoroji yekucheka nelaser

Nheyo yekushanda kwekucheka kwelaser

Kucheka kweLaser kwakagadzirwa nejenareta yelaser inoburitsa danda relaser rine simba guru. Danda relaser rinozobva ratariswa nelenzi roita nzvimbo diki diki yechiedza chine simba guru. Nekutarisa nzvimbo yechiedza panzvimbo dzakakodzera, zvinhu zvinotora simba kubva kuchiedza chelaser zvobva zvapera, zvonyungudutsa, zvobvisa simba kana kusvika panzvimbo yekupisa. Ipapo mhepo inobatsira ine simba guru (CO2, Oxygen, Nitrogen) ichabvisa marara. Musoro welaser unofambiswa nemota yeservo inodzorwa neprogram uye inofamba nenzira yakatarwa pazvinhu kuitira kucheka zvidimbu zvebasa zvemaumbirwo akasiyana.

Mapoka ejenareta dzelaser (manyuko elaser)

Chiedza chinogona kupatsanurwa nechiedza chitsvuku, chiedza cheorenji, chiedza cheyero, chiedza chegirini nezvimwewo. Chinogona kunyudzwa kana kuratidzwa nezvinhu. Chiedza cheLaser chiedzawo. Uye chiedza cheLaser chine wavelength yakasiyana chine maficha akasiyana. Gain medium yejenareta yelaser inova ndiyo medium inoshandura magetsi kuita laser inosarudza wavelength, simba rekubuda uye mashandisirwo elaser. Uye gain medium inogona kuva gas state, liquid state uye solid state.

1. Laser inonyanya kushandiswa pakugadzira gas state iCO2 laser;

2. Laser yakasimba inowanzo shandiswa inosanganisira fiber laser, YAG laser, laser diode uye ruby ​​laser;

3. Laser yemhando yeLiquid inoshandisa zvimwe zvinwiwa zvakaita seorganic solvent senzira inoshanda yekugadzira chiedza chelaser.

Zvinhu zvakasiyana zvinotora chiedza chelaser chema wavelength akasiyana. Saka, jenareta yelaser inofanira kusarudzwa nokungwarira. Kuindasitiri yemotokari, laser inonyanya kushandiswa ifiber laser.

Nzira dzekushanda kwe laser source

Chitubu cheLaser chinowanzova nenzira nhatu dzekushanda: continuous mode, modulation mode uye pulse mode.

Kana iri nzira inoenderera mberi, simba remagetsi rinobuda nelaser harichinji. Izvi zvinoita kuti kupisa kunopinda muzvinhu zvive zvakaenzana, saka zvakakodzera kuchekwa nekukurumidza. Izvi hazvingogone kungovandudza mashandiro ekushanda asiwo zvinokanganisa kushanda kwenzvimbo inokanganisa kupisa.

Pasi pemodulation mode, simba rekubuda kwelaser rakaenzana nebasa rekumhanya kwekucheka. Inogona kuchengetedza kupisa kunopinda muzvinhu zviri padanho rakaderera nekuderedza simba panzvimbo imwe neimwe kuitira kudzivirira kucheka kusina kuenzana. Sezvo kutonga kwayo kwakaoma zvishoma, kushanda zvakanaka hakuna kukwira uye kunogona kushandiswa kwenguva pfupi chete.

Pulse mode inogona kukamurwa kuita normal pulse mode, super pulse mode uye super-intense pulse mode. Asi musiyano wavo mukuru ingori mutsauko wesimba. Vashandisi vanogona kuita sarudzo zvichibva pane hunhu hwezvinhu uye kunyatsorongeka kwechimiro.

Mukupfupisa, laser inowanzo shanda pasi pe continuous mode. Asi kuti uwane mhando yekucheka yakagadziriswa, kune mamwe marudzi ezvinhu, zvinodikanwa kugadzirisa kumhanya kwekudya, senge kukurumidza, kudimbura nekukurumidza uye kunonoka pakutenderera. Saka, pasi pe continuous mode, hazvina kukwana kungodzikisa simba. Simba re laser rinofanira kugadziriswa nekuchinja pulse.

Iyo parameter yekuisa laser yekucheka

Zvichienderana nezvinodiwa zvechigadzirwa zvakasiyana, zvakakosha kuramba uchigadzirisa maparamita pasi pemamiriro akasiyana ekushanda kuti uwane maparamita akanakisa. Kurongeka kwenzvimbo yekucheka nelaser kunogona kusvika 0.08mm uye kurongeka kwenzvimbo inodzokororwa kunogona kusvika 0.03mm. Asi mumamiriro ezvinhu chaiwo, kushivirira kushoma kwakafanana ne±0.05mm yekuvhura uye ±0.2mm yenzvimbo ine maburi.

Zvinhu zvakasiyana uye ukobvu hwakasiyana zvinoda simba rakasiyana rekunyungudutsa. Saka, simba rinodiwa re laser rinobuda rakasiyana. Mukugadzira, varidzi vemafekitori vanofanirwa kuyera pakati pekumhanya kwekugadzira uye mhando uye kusarudza simba rakakodzera rekubuda uye kumhanya kwekucheka. Saka, nzvimbo yekucheka inogona kuva nesimba rakakodzera uye zvinhu zvinogona kunyungudutswa zvinobudirira.

Kushanda zvakanaka kwemagetsi nelaser kuita simba relaser kuri pakati pe30%-35%. Izvi zvinoreva kuti kana simba remagetsi riine 4285W ~ 5000W, simba remagetsi rinosvika 1500W chete. Simba remagetsi rinoshandiswa zvakanyanya kupfuura simba remagetsi rinobuda. Kunze kweizvozvo, maererano nemutemo wekuchengetedza simba, rimwe simba rinoshanduka kuita kupisa, saka zvakakosha kuwedzera chitofu chemvura cheindasitiri .

S&A ikambani inogadzira machillers akavimbika ine ruzivo rwemakore gumi nemapfumbamwe muindasitiri yelaser. Machillers emvura emumaindasitiri ainogadzira akakodzera kutonhodza malaser akasiyana-siyana. Fiber laser, CO2 laser, UV laser, ultrafast laser, laser diode, YAG laser, kungodudza zvishomanana. Machillers ese eS&A akagadzirwa nezvinhu zvakaedzwa nenguva kuti ave nechokwadi chekuti anoshanda zvakanaka kuitira kuti vashandisi vagone kuva nechokwadi chekuashandisa.
