Lasers tau nyiam muaj koob meej rau ntau lub xyoo tam sim no. Nws yog qhov zoo heev los ua cov laser nyob hauv tsev. Koj tsuas yog yuav tsum muaj qee cov kev txawj ntse hauv kev ua haujlwm nrog hlau soldering thiab paub qhov txawv ntawm "+" los ntawm "-" thaum txhim kho hauv Circuit Court.
Cov Lus Qhia
Kauj ruam 1
Yog tias koj xav tau lub laser muaj zog, nrog hluav taws xob ntev txog 200 mW, tom qab ntawd pom cov DVD haum nrog lub tsheb ua haujlwm thiab lub taub hau laser tau nruab rau nws. Txiav txim siab saib koj xav kom muaj qhov ci, xim liab lossis xiav-violet. Xaiv cov nqaj ntawm lub teeb nyem nrog lub ntsej muag kom tsim nyog raws qhov ntev, uas sib txawv ntawm 380 nm txog 800 nm, los ntawm saib cov yam ntxwv ntawm ntau emitters. Lub zog hluav taws xob tuaj yeem tau los ntawm kev tshem tawm tib lub block, tab sis los ntawm CD tsav. Ob lub drive yuav tsum yog cov kws sau ntawv. Tau txais cov hluav taws xob tsis muaj zog los ntawm qee lub tshuab luam ntawv, barcode scanner, nas.

Qhov tsim ntawm tus tsav tuaj yeem sib txawv. Ua tib zoo nrog nws kom koj tuaj yeem tawm ntawm ob peb screws tsis muaj teeb meem. Lub ntsej muag laser tau teeb tsa ntawm cov lus qhia txog lub vev xaib, uas koj tuaj yeem yooj yim tshem tawm tom qab tshem tawm cov fasteners. Tom qab ntawd, tshem tawm cov DVD kho qhov muag tawm ntawm qhov thaiv, muaj yav tas los "zaum" tag nrho cov coj ntawm cov ntawv ci, lossis ua tib zoo qhwv nrog daim ntaub nyias nyias, yog li tshem tawm qhov kev puas tsuaj zoo li qub. Txiav txim siab rau txhua ntawm 3 qhov kev txiav txim siab:
- 1 zis fais fab mov "+";
- 2 zis fais fab mov "-";
- 3 tus pin tsis siv.

Lub zog muab rau lub laser diode yog 3 volts. Siv ob lub roj teeb "ntiv tes". Koj tuaj yeem nqa cov yas tsis tu ncua rau kev siv fais fab, tom qab ntawd sib dhos ua ke ib qho kev tswj hwm hluav taws xob ntxiv. Qhov kev xaiv no muab rau koj ntev dua kev siv koj lub laser. Nrhiav 10pF ceramic capacitor thiab 100uF / 16V polarized capacitor.
Tom qab ntawd, raws li phau ntawv siv, xaiv tus stabilizer sib haum rau qhov ntsuas hluav taws xob ntawm 3 V, piv txwv li, KR1158EN3V. Tsis tas li ntawd, xaiv qhov chaw nyob uas tsim nyog thiab microswitch.

Pib tag nrho cov txheej txheem los ua ke los ntawm soldering cov hlab ntsha mus rau lub laser diode coj, tshem tawm cov ntawv ci tiv thaiv thiab solder polarity capacitor. KREN muaj peb qhov kev xaus:
- 1 ruaj khov fais fab mov + 3V;
- 2 hom;
- 3 input voltage.
Ib zaug ntxiv, nruj me ntsis coj mus rau hauv tus account lub polarity ntawm stabilizer thiab laser diode, unsolder no ntu ntawm Circuit Court. Tam sim no solder lub microswitch rau hauv qhib Circuit Court ntawm lub hwj huam hluav taws xob thiab lub Circuit Court koj sib sau ua ke. Kos rau lub Circuit Court sib sau ua ke thiab sim tig nws.
Kauj ruam 5
Ua tib zoo ntim cov khoom tsim tawm thiab muab tso rau hauv lub cev ntawm lub teeb nyem, tom qab tshem lub khob ntawm lub teeb nyem. Koj tuaj yeem ua lub laser koj tus kheej tsis muaj kev rhuav tshem ntawm kev tsav, tab sis mus ncig ntawm cov khw muag khoom online thiab tuaj tos cov khoom tsim nyog (lossis kev txiav txim) cov chav laser.
