Dab Tsi Yog Cov Vuam Ua Haujlwm Ntawm Cov Hlau Thaiv Nruab Nrab ?
Cov txheej txheem vuam ntawm cov hlau txuas xaim khi suav nrog Crimping, ultrasonic vuam, xaim hlua hlau, xaim hlua khi hlua khi thiab lwm yam. Cia peb kawm qhov kev paub ntawm ultrasonic hlau xaim hlua ua ke.
1. Wir sam xauv nees crimping
Qhov feem ntau dav siv hom ntawm kev ua lag luam, crimping yog kev siv cov terminals mus nias ntau strands ntawm cov hlau ua ke los ua ib qhov sib koom ua ke. Hauv qab cov kabmob, qhov ob txoj haujlwm ua haujlwm tiav qhov sib thooj ntawm cov khoom siv khov kho hauv lub xeev khov kho, tseem hu ua solid state welding. Cov txheej txheem feem ntau siab vuam txheej txheem yog kev sib tw taub qab vuam. Thaum tam sim no dhau los ntawm kev sib txuas ntawm qhov kawg ntawm ob txoj haujlwm, qhov kub nce vim qhov ua haujlwm loj, thiab thaum rhuab mus rau lub xeev yas, qhov kev sib txuas yog ua ke nyob rau hauv lub siab axial. Qhov kom zoo dua yog tias tsis muaj qhov sau cov khoom xav tau, kev tsim khoom siv tau nrawm heev, thiab cov cuab yeej siv tau yooj yim; qhov tsis zoo yog tias muaj kev pheej hmoo ntawm thim rov qab rau hauv cov ntawv hlau, oxidation thiab xeb hauv kev ua haujlwm hnyav, thiab txhua qhov kev pheej hmoo yuav ua rau muaj kev sib cuag tsis zoo.
2. Ultrasonic wir siv hlua hlau
Tam sim no, nrov dua ultrasonic vuam yog siv kev sib txuas ntawm lub cev lub cev ntawm kev vibration ultrasonic los ua ke cov hlau xaus . Daim ntawv thov ntawm lub tsheb txoj hlua khau yog thawj zaug nrov nyob hauv Europe thiab Asmeskas. Lub hauv paus ntsiab lus yog tias cov pwm tuaj yeem tsim kev co tshee ntawm 20,000- 4 0,000 zaug ib pliag, uas tuaj yeem ua rau cov xov hlau ntawm ob qho tib si kawg kev sib txuas, thiab thaum cov xaim tau nrawm thiab txhuam, kub yuav tsim kom muaj qhov txuas ntxiv dag zog. Qhov kom zoo dua yog cov hluav taws xob zoo sib xws (cov xoom tsis kam tiv thaiv), uas yog qhov tsis txaus siab rau qhov phom sij ntawm xeb thiab xeb hauv cov mob hnyav, thiab lub zog tensile thiab tsim kua muag muaj nyob rau hauv txoj kab nrog cov kev xav tau siab, uas tuaj yeem kho tau sai thiab ua rau tus nqi tsawg heev . Qhov tsis zoo yog tias u ltrasonic xaim hlua cuab yeej siv yog qhov tseem ceeb thiab tau siv nyiaj (xaim hlua hlau pwm). Txawv tooj liab hlau txoj hlua hlau txoj kev vuam zoo ntawm vuam cov khoom siv tsis yaj, tsis yooj yim rau cov yam ntxwv hlau. Lub tshuab hluav taws xob zoo tom qab soldering, qis heev lossis ze li xoom resistivity. Cov kev txwv qis rau vuam hlau saum npoo, oxidation lossis electroplating tuaj yeem txuas, vuam lub sijhawm yog luv, tsis muaj flux, roj, solder, tsis muaj txim taws, kev tiv thaiv ib puag ncig thiab kev nyab xeeb.
3. Hlau sam xauv hlau
Lub workpiece interface yog rhuab mus rau lub xeev yaj thaum lub sijhawm vuam, thiab cov txheej txheem vuam yog ua tiav yam tsis muaj lub siab. Cov hlua hlau txuas lub pob zeb txuas ua ke los ua lub kav hlau txuas, thiab lub zog hluav taws xob muaj qhov loj, uas zoo heev txo cov kev pab cuam lub neej ntawm cov hlua hlau.
4. Hlau txoj hlua khi txhawm
Siv cov khoom siv hlau qis dua qhov chaw yaj ntawm qhov ua haujlwm tawm tau ua cov khoom tawg, qhov chaw ua haujlwm thiab cov khoom tawg tau muab kho kom kub txog qhov kub siab dua qhov chaw melting ntawm cov khoom tawg thiab qis dua qhov chaw melting ntawm lub workpiece, thiab lub workpiece. yog ntub los ntawm cov kua hluav taws xob cov khoom siv, ua kom lub ntsej muag sib txawv thiab ua tiav qhov nruab nrab ntawm kev sib txig nrog qhov chaw ua haujlwm. Cov txheej txheem ntawm kev sib cais ua kom tiav kom tiav vuam. Nws yog qhov yooj yim rau kev ua kom overheating, embrittlement, tawv lossis tawv muag.
