Kuongorora Mamiriro Azvino Uye Mikana Yekugadzirwa kweGirazi neLaser

Tekinoroji yekugadzira laser yave nekukura nekukurumidza mumakore gumi apfuura, uye kushandiswa kwayo kukuru kuri kugadzirwa ne laser yezvinhu zvesimbi. Kucheka ne laser, kusanganisa ne laser, uye kufukidza simbi ne laser ndezvimwe zvezvinhu zvakakosha mukugadzirwa ne laser yesimbi. Zvisinei, sezvo huwandu hwezvinhu huchiwedzera, kusanganiswa kwezvigadzirwa zve laser kwave kwakanyanya, zvichideredza kukura kwemusika we laser. Saka, kuti zvibudirire, kushandiswa ne laser kunofanirwa kuwedzera munzvimbo itsva dzezvinhu. Zvinhu zvisiri zvesimbi zvakakodzera kushandiswa ne laser zvinosanganisira machira, girazi, mapurasitiki, mapolymer, ceramics, nezvimwe. Chinhu chimwe nechimwe chinosanganisira maindasitiri akawanda, asi matekiniki ekugadzirisa akakura atovapo, zvichiita kuti kutsiva ne laser kuve basa riri nyore.

Kuti upinde mumunda wezvinhu zvisiri zvesimbi, zvakakosha kuongorora kana kushandisa laser nezvinhu izvi zvichikwanisika uye kana paine matambudziko achaitika. Parizvino, girazi ndiro nzvimbo huru ine kukosha kwakanyanya uye mukana wekushandisa batch laser processing applications.

Nzvimbo Yakakura Yekucheka Girazi neLaser

Girazi chinhu chakakosha chinoshandiswa mumaindasitiri akasiyana-siyana akadai semotokari, kuvaka, zvekurapa, uye zvemagetsi. Mashandisirwo aro anotangira pamafirita madiki anoyera ma micrometer kusvika kumapaneru makuru egirazi anoshandiswa mumaindasitiri akadai semotokari kana kuvaka.

Girazi rinogona kuiswa muzvikamu zvakaita segirazi re optical, girazi re quartz, girazi re microcrystalline, girazi re sapphire, nezvimwewo. Hunhu hwakakosha hwegirazi ndehwekupfava kwaro, izvo zvinounza matambudziko makuru kune nzira dzechinyakare dzekugadzirisa. Nzira dzechinyakare dzekucheka girazi dzinowanzo shandisa zvishandiso zve alloy kana dhaimani, nemaitiro ekucheka akakamurwa kuita matanho maviri. Chekutanga, mutswe unogadzirwa pamusoro pegirazi uchishandisa chishandiso chine mativi edhaimani kana vhiri rekukuya rakaoma. Chechipiri, nzira dzemakanika dzinoshandiswa kuparadzanisa girazi nemutsetse wekupwanyika. Zvisinei, maitiro aya echinyakare ane matambudziko akajeka. Haashande zvakanaka, zvichikonzera mipendero isina kuenzana inowanzoda kukweshwa kwechipiri, uye anogadzira marara akawanda neguruva. ​​Uyezve, pamabasa akadai sekuboora makomba pakati pemagirazi kana kucheka maumbirwo asina kurongeka, nzira dzechinyakare dzakaoma zvikuru. Apa ndipo panowanikwa mabhenefiti egirazi rekucheka ne laser. Muna 2022, mari yekutengesa muindasitiri yegirazi yeChina yaive inosvika mabhiriyoni 744.3 eyuan. Mwero wekupinda kwetekinoroji yekucheka ne laser muindasitiri yegirazi uchiri muchikamu chayo chekutanga, zvichiratidza nzvimbo yakakura yekushandiswa kwetekinoroji yekucheka ne laser sechinotsiva.

Kucheka neLaser yeGirazi: Kubva paNharembozha Zvichienderera Mberi

Kucheka nelaser yegirazi kunowanzo shandisa musoro weBezier unotarisa kuti ugadzire simba repamusoro-soro uye density laser beams mukati megirazi. Nekutarisa Bezier beam mukati megirazi, inobvisa zvinhu ipapo ipapo, zvichiita kuti pave nemhepo inopisa, iyo inokura nekukurumidza kuti igadzire mitswe pamusoro nepazasi. Mitswe iyi inoumba chikamu chekucheka chine maburi madiki asingaverengeki, zvichiita kuti zvicheke kuburikidza nekupwanyika kwekunze.

Nekufambira mberi kukuru mu tekinoroji yelaser, huwandu hwesimba hwakawedzerawo. Laser yegirini ine nanosecond ine simba rinopfuura 20W inogona kucheka girazi zvinobudirira, nepo laser yepicosecond ultraviolet ine simba rinopfuura 15W inocheka girazi zviri nyore pasi pe2mm ukobvu. Kune makambani ekuChina anogona kucheka girazi kusvika pa17mm ukobvu. Girazi rekucheka nelaser rinozvirumbidza nekushanda kwaro kwepamusoro. Semuenzaniso, kucheka girazi redhiyamita ye10cm pagirazi rine gobvu re3mm kunotora masekondi gumi chete nekucheka nelaser zvichienzaniswa nemaminitsi akati wandei nemapanga emuchina. Micheto yakachekwa nelaser yakatsetseka, ine kurongeka kwenotch kusvika 30μm, zvichibvisa kudiwa kwemuchina wechipiri wezvigadzirwa zvemaindasitiri.

Magirazi ekucheka nelaser inyaya itsva, yakatanga makore matanhatu kusvika manomwe apfuura. Indasitiri yekugadzira mafoni yaive pakati pevakatanga kushandisa, vachishandisa laser cutting pamagirazi ekamera uye yakawedzera nekushandiswa kwechinhu chinocheka nelaser. Nekufarirwa kwemafoni ane skrini yakazara, kucheka nelaser chaiyo kwemagirazi ese ane skrini hombe kwakawedzera kugona kwekugadzira magirazi. Kucheka nelaser kwave kwakajairika kana zvasvika pakugadzirisa zvikamu zvegirazi zvemafoni. Maitiro aya anonyanya kukonzerwa nemidziyo inogadzirwa otomatiki yegirazi rekuvhara mafoni, michina yekucheka nelaser yemalenzi ekudzivirira kamera, uye michina yakangwara yekugadzira magirazi ekuchera nelaser.

Girazi remagetsi rinoiswa mumotokari riri kushandisa zvishoma nezvishoma kucheka kweLaser

Masikirini anoiswa mumotokari anoshandisa magirazi akawanda, kunyanya masikirini ekudzora epakati, masisitimu ekufambisa, madashcam, nezvimwewo. Mazuva ano, mota zhinji dzemagetsi dzine masisitimu akangwara uye masikirini makuru ekudzora epakati. Masisitimu akangwara ave echinyakare mumotokari, nemasikirini makuru uye akawanda, pamwe nemasikirini akakombama e3D zvishoma nezvishoma ari kuve akakurumbira pamusika. Magirazi anofukidza masikirini anoiswa mumotokari anoshandiswa zvakanyanya nekuda kwehunhu hwawo hwakanaka, uye girazi repamusoro rakakombama rinogona kupa ruzivo rwakanaka kune indasitiri yemotokari. Zvisinei, kuomarara kwakanyanya uye kuputsika kwegirazi kunonetsa kugadzirisa.

Zvidzitiro zvegirazi zvinoiswa mumotokari zvinoda kunyatsoshanda, uye kushivirira kwezvikamu zvechimiro zvakaunganidzwa kudiki kwazvo. Kukanganisa kukuru panguva yekucheka zvidzitiro zvesikweya/bhawa kunogona kukonzera matambudziko ekubatanidza. Nzira dzechinyakare dzekugadzirisa dzinosanganisira matanho akawanda akadai sekucheka mavhiri, kupwanyika nemaoko, kuumba CNC, uye chamfering, pakati pezvimwe. Sezvo iri michina yekugadzirisa, inosangana nematambudziko akadai sekushanda zvishoma, mhando isina kunaka, mwero wakaderera wekukohwa, uye mutengo wakakwira. Mushure mekucheka mavhiri, CNC yekugadzira chimiro chegirazi remota imwe chete inogona kutora kusvika maminetsi 8-10. Nema laser anokurumidza kupfuura 100W, girazi re17mm rinogona kuchekwa kamwe chete; kubatanidza maitiro akawanda ekugadzira kunowedzera kushanda ne80%, apo laser imwe yakaenzana nemichina yeCNC makumi maviri. Izvi zvinovandudza zvikuru kugona uye zvinoderedza mari yekugadzirisa mayuniti.

Mamwe Mashandisirwo eLaser muGirazi

Girazi reQuartz rine chimiro chakasiyana, zvichiita kuti zviome kupatsanura kucheka ne lasers, asi femtosecond lasers inogona kushandiswa pakucheka girazi re quartz. Uku kushandiswa kwe femtosecond lasers pakugadzira nemazvo uye kucheka girazi re quartz. Tekinoroji yeFemtosecond laser tekinoroji yekuvandudza mashandiro iri kukura nekukurumidza mumakore achangopfuura, ine kunyatsogadzirisa kwakanyanya uye kumhanya, inokwanisa kucheka nekugadzira kubva pa micrometer kusvika nanometer-level uye processing pamusoro pezvinhu zvakasiyana-siyana. Tekinoroji yekutonhodza laser inosiyana zvichienderana nekuchinja kwezvinodiwa pamusika. Semugadziri ane ruzivo rwechiller anovandudza edu chitonho chemvura Mitsetse yekugadzira inoenderana nemafambiro emusika, TEYU CWUP-Series Ultrafast Laser Chillers yemugadziri weChiller inogona kupa mhinduro dzinoshanda uye dzakagadzikana dzekutonhodza dzepicosecond nefemtosecond lasers dzine simba rinosvika 60W.

Kupinza girazi neLaser tekinoroji itsva yakabuda mumakore maviri kusvika matatu apfuura, yakatanga kuoneka muGermany. Parizvino, mayuniti mashoma chete muChina, akadai seHuagong Laser, Xi'an Institute of Optics and Fine Mechanics, uye Harbin Hit Weld Technology, akapfuura nepamuchina uyu. Pasi pesimba rema "high-power, ultra-short pulse lasers", mafungu ekumanikidzwa anogadzirwa nema "laser" anogona kugadzira "microcracks" kana "stress concentrations" mugirazi, izvo zvinogona kukurudzira kubatana pakati pezvidimbu zviviri zvegirazi. Girazi rakabatana mushure mekupinza rakasimba kwazvo, uye zvatove zvinokwanisika kuita "tight welding" pakati pegirazi rine gobvu re3mm. Mune ramangwana, vaongorori vari kutarisawo pakupinza girazi nezvimwe zvinhu. Parizvino, maitiro matsva aya haasati ashandiswa zvakanyanya muma "batches", asi kana akura, pasina mubvunzo achaita basa rakakosha mune mamwe mashandisirwo epamusoro-soro.
