Dawb photoelectric soldering hlau tsis tuaj yeem kho qhov kub thiab txias yuav kho li cas
Cov lus nug nyob rau hauv kev tsom xam ntawm lub hauv paus ntsiab lus ntawm kev ua hauj lwm ntawm cov dawb photoelectric soldering hlau taub hau
Cov lus piav qhia ntawm cov txheej txheem ua haujlwm ntawm cov thermocouple hauv cov ntawv qub tau hais, yog li nws yuav ua rau tsis meej pem. Rau qhov yooj yim ntawm kev piav qhia, qhov voltage ntawm txhua tus pin ntawm LM358 yog sawv cev los ntawm Vn.
Qhov voltage V3 generated ntawm ob kawg ntawm lub thermocouple yog qhov tsis muaj zog, uas tuaj yeem pom los ntawm qhov sib faib voltage ntawm LM358 tus pin 2 tsis kam, qhov siab tshaj plaws yog li 100mV. Qhov tseeb, lub thermocouple tsuas yog los ua si thaum T12 de-energized!
Cov ntawv qub tsis tau piav qhia txog lub sijhawm sib tw uas muaj 205 resistors thiab 104 capacitors ntawm 6 tus pin. Qhov tseeb, T12 tsuas yog siv rau hauv lub sijhawm no. Thaum lub 104 capacitor raug them kom V6 siab dua V5, nws yuav raug kaw; Tom qab fais fab tuag, V3 tsis yog 24V, thiab qhov voltage V3 ntawm lub thermocouple thiab cov nqi teev V2 Hauv kev sib piv, yog tias nws qis, V1 yog qis, lub capacitor 104 yog tawm ntawm lub sijhawm, V6 qis dua V5, thiab lub voj voog ntawm T12 re-energization pib, thiaj li hais tias qhov kub ntawm cov hlau soldering yog khaws cia tas li.
Qhov kub thiab txias V2 muaj qhov tsawg kawg nkaus tus nqi kwv yees li 10mV thiab tus nqi siab tshaj ntawm 100mV. T12 yuav txuas ntxiv ua kom sov los ntawm hluav taws xob txij li nws tau siv rau kom txog thaum V3 siab dua V2, thiab tom qab ntawd nkag mus rau qhov ntsuas kub tsis tu ncua.
Tsuas yog lub sij hawm capacitor 104, lwm cov capacitor yog lim capacitor. Tsis tas li ntawd, cov cim D thiab S ntawm TPC8107 ntawm daim duab yog thim rov qab.
Qhov kub ntawm cov dawb photoelectric soldering hlau tsis ruaj khov
Yog tias tsis muaj teeb meem nrog cov cua sov ntawm cov hluav taws xob soldering hlau, nws txhais tau hais tias kev sib cuag ntawm cov hlau taub hau thiab cov tub ntxhais cua sov tsis zoo, cov cua sov hloov tsis zoo, los yog cov hlau nplaum yog oxidized.
Schematic daim duab ntawm dawb photoelectric soldering hlau
Baiguang soldering hlau yog hluav taws xob soldering hlau tsim los ntawm Baiguang Company.
Tam sim no, muaj cov khoom siv hluav taws xob hloov hluav taws xob tuaj txawv teb chaws, cov khoom siv hluav taws xob hauv tsev dawb photoelectric soldering irons thiab ntau yam khoom siv dawb photoelectric soldering hlau nyob hauv khw; tam sim no, hluav taws xob soldering hlau tau tsim los ntawm cov hluav taws xob zoo tib yam rau cov hluav taws xob hloov hluav taws xob, thiab tam sim no mus rau digital adjustable qhov kub thiab txias hluav taws xob soldering irons.
