Laser welding inotarisa nzira

Laser weldingkuisa pfungwa

Kana laser ikasangana nemudziyo mutsva kana kuita kuyedza kutsva, danho rekutanga rinofanira kunge rakatarisa. Chete nekutsvaga iyo yakatarisa ndege inogona kuita mamwe maparamita ekuita senge defocusing uwandu, simba, kumhanya, nezvimwe zvigadziriswe nenzira kwayo, kuitira kuti uve nekunzwisisa kwakajeka.

Nheyo yekutarisa ndeiyi inotevera:

Chekutanga, simba reiyo laser beam harina kugovaniswa zvakaenzana. Nekuda kwechimiro chehourglass kuruboshwe uye kurudyi mativi egirazi rinotarisa, simba rinonyanya kunyura uye rakasimba pane chinzvimbo chechiuno. Kuve nechokwadi chekugadzirisa kushanda zvakanaka uye mhando, zvinowanzodikanwa kutsvaga iyo yakatarisana nendege uye kugadzirisa defocusing chinhambwe zvichibva pane izvi kugadzirisa chigadzirwa. Kana pasina ndege yakatarisa, inotevera paramita haizokurukurwa, uye kugadzirisa midziyo mitsva kunofanirawo kutanga yaona kana ndege yakatarisana neyakarurama. Naizvozvo, kutsvaga iyo yakatarisa ndege ndicho chidzidzo chekutanga mu laser tekinoroji.

Sezvinoratidzwa muFigure 1 uye 2, iyo yakatarisana nekudzika hunhu hwemalaser matanda ane akasiyana masimba akasiyana, uye iyo galvanometers uye imwechete modhi uye multimode lasers zvakare akasiyana, anonyanya kuratidzwa mukugovera kwenzvimbo yekugona. Mamwe acho akati dhumana, asi mamwe ari mutete. Naizvozvo, kune nzira dzakasiyana dzekutarisa dzeakasiyana laser matanda, ayo anowanzo kukamurwa kuita matanho matatu.

Tungamira saizi yenzvimbo pamadaro akasiyana

Slanting nzira:

1. Chekutanga, tarisa huwandu hwendege yakatarisa nekutungamira nzvimbo yechiedza, uye sarudza nzvimbo inopenya uye diki pane inotungamira mwenje senzvimbo yekuyedza yekutanga;

2. Kuvakwa kwepuratifomu, sezvakaratidzwa mumufananidzo 4

2. Kuchengetedza kwe diagonal sitiroko

(1) Kazhinji, mahwendefa esimbi anoshandiswa, ane semiconductors mukati me500W uye optical fibers akatenderedza 300W; Iyo yekumhanya inogona kuiswa ku80-200mm

(2) Iyo yakakura kona yakarerekera yendiro yesimbi, zviri nani, edza kutenderedza 45-60 madhigirii, uye woisa nzvimbo yepakati panzvimbo yakakasharara ine nzvimbo ine mwenje diki uye inopenya;

(3) Wobva watanga tambo, tambo inoita sei? Muchirevo, mutsara uyu uchagovaniswa zvakaenzanirana kumativi epakati, uye trajectory ichaita nzira yekuwedzera kubva pakukura kusvika kudiki, kana kuwedzera kubva kudiki kusvika kuhombe uyezve kuderera;

(4) Semiconductors inowana iyo thinnest poindi, uye ndiro yesimbi inoshandukawo chena panzvimbo yepakati neinooneka mavara mavara, ayo anogona zvakare kushanda sehwaro hwekutsvaga nzvimbo yekutarisa;

(5) Chechipiri, iyo fiber optic inofanira kuedza kudzora kuseri kwe micro kupinza zvakanyanya sezvinobvira, ne micro kupinza panzvimbo yakatarisa, zvichiratidza kuti nzvimbo yakatarisa iri pakati pekumashure kwe micro kupinza kureba. Panguva ino, iyo yakaomesesa yekumisikidzwa kwenzvimbo yekutarisa inopedzwa, uye mutsara welaser yakabatsira chinzvimbo inoshandiswa padanho rinotevera.

3. Nhanho inotevera ndeyekuyera iyo workpiece, gadzirisa mutsara welaser kuti uenderane nekutarisa nekuda kwechiedza chekutungamira nzvimbo, inova nzvimbo yekutarisa, uye wozoita yekupedzisira focal ndege yekuongorora.

(1) Verification inoitwa kuburikidza nekushandiswa kwepulse point. Nheyo yacho ndeyokuti pfarivari dzinomwayiwa panzvimbo yepakati, uye hunhu hwenzwi huri pachena. Pane muganho pakati pemiganho yekumusoro neyezasi yenzvimbo yakatarisana, apo ruzha rwakasiyana zvakanyanya kubva kune masplash uye mazhenje. Rekodha iyo yepamusoro uye yakaderera miganho yenzvimbo yekutarisa, uye yepakati ndiyo inotarisisa,

(2) Gadzirisa mutsara welaser inopindirana zvakare, uye iyo yakatarisa yakatomisikidzwa nemhosho yeanenge 1mm. Inogona kudzokorora chinzvimbo chekuyedza kuti uvandudze huchokwadi.

Kune zvakare nzira yekudonhedza: inokodzera fiber lasers ine yakakura kudzika kwakadzika uye yakakosha shanduko muhukuru hwemavara munzira yeZ-axis. Nekudzvanya mutsara wemadota kuti uone mafambiro ekuchinja kwemapoinzi ari pamusoro pesimbi ndiro, nguva imwe neimwe iyo Z-axis inochinja ne 1mm, iyo inodhindwa pandiro yesimbi inoshanduka kubva kuhombe kuenda kudiki, uyezve kubva kudiki kuenda kudiki. hombe. Nzvimbo diki ndiyo inotarisisa.
