在進(jin)行(xing)超(chao)(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)焊(han)(han)接(jie)時(shi)(shi)，使用多(duo)大(da)振蕩頻率(lv)、輸出(chu)(chu)功(gong)(gong)率(lv)及振幅范(fan)圍等，要(yao)(yao)根據工(gong)(gong)件(jian)(jian)(jian)(jian)(jian)的(de)焊(han)(han)線面(mian)積、材料(liao)、工(gong)(gong)件(jian)(jian)(jian)(jian)(jian)內是(shi)(shi)否(fou)氣密有(you)電子(zi)，是(shi)(shi)否(fou)元器件(jian)(jian)(jian)(jian)(jian)等因素來決定。認為(wei)(wei)功(gong)(gong)率(lv)越大(da)越好(hao)，這是(shi)(shi)一(yi)個誤解。如(ru)(ru)(ru)果對超(chao)(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)相(xiang)關技術(shu)不是(shi)(shi)很了解，最好(hao)請教超(chao)(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)焊(han)(han)接(jie)機(ji)生(sheng)產(chan)廠家(jia)的(de)技術(shu)人員。下面(mian)固(gu)特超(chao)(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)簡單介(jie)紹下超(chao)(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)焊(han)(han)接(jie)時(shi)(shi)需(xu)要(yao)(yao)注意的(de)幾個要(yao)(yao)點，希望對您有(you)幫助。 1、焊(han)(han)接(jie)時(shi)(shi)兩種(zhong)工(gong)(gong)件(jian)(jian)(jian)(jian)(jian)的(de)可焊(han)(han)接(jie)性(xing)不同(tong)(tong)材質(zhi)(zhi)之間有(you)的(de)能(neng)(neng)更好(hao)地熔(rong)接(jie)，有(you)的(de)是(shi)(shi)基本可相(xiang)熔(rong)，有(you)的(de)是(shi)(shi)不相(xiang)熔(rong)的(de)。同(tong)(tong)一(yi)材料(liao)從原理上來講是(shi)(shi)可以(yi)焊(han)(han)接(jie)的(de)，但(dan)是(shi)(shi)當(dang)(dang)要(yao)(yao)焊(han)(han)接(jie)的(de)工(gong)(gong)件(jian)(jian)(jian)(jian)(jian)的(de)熔(rong)點大(da)于350℃時(shi)(shi)，就(jiu)(jiu)不適(shi)合(he)用超(chao)(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)焊(han)(han)接(jie)了。因為(wei)(wei)超(chao)(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)是(shi)(shi)瞬(shun)間使工(gong)(gong)件(jian)(jian)(jian)(jian)(jian)分子(zi)溶化，最好(hao)是(shi)(shi)在3秒之內。如(ru)(ru)(ru)果超(chao)(chao)(chao)(chao)(chao)過(guo)(guo)3秒，不能(neng)(neng)良好(hao)熔(rong)接(jie)，就(jiu)(jiu)需(xu)要(yao)(yao)選擇其(qi)它焊(han)(han)接(jie)工(gong)(gong)藝。一(yi)般來講ABS材質(zhi)(zhi)是(shi)(shi)最容(rong)易焊(han)(han)接(jie)，尼龍或PP料(liao)是(shi)(shi)一(yi)般可焊(han)(han)接(jie)的(de)。 2、焊(han)(han)模(mo)(mo)(mo)結構需(xu)要(yao)(yao)嚴格檢驗正規超(chao)(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)模(mo)(mo)(mo)生(sheng)產(chan)進(jin)料(liao)都有(you)一(yi)套嚴格的(de)檢驗程序(xu)，加(jia)工(gong)(gong)尺寸都是(shi)(shi)經(jing)過(guo)(guo)計算機(ji)軟件(jian)(jian)(jian)(jian)(jian)模(mo)(mo)(mo)擬和校驗后(hou)加(jia)工(gong)(gong)出(chu)(chu)來的(de)，品質(zhi)(zhi)才(cai)有(you)保障(zhang)。這些工(gong)(gong)序(xu)一(yi)般作坊是(shi)(shi)無法做到的(de)，如(ru)(ru)(ru)不經(jing)過(guo)(guo)合(he)理地設(she)計，做出(chu)(chu)的(de)模(mo)(mo)(mo)具，在焊(han)(han)接(jie)小工(gong)(gong)件(jian)(jian)(jian)(jian)(jian)時(shi)(shi)，反(fan)應(ying)問題還不明顯，當(dang)(dang)大(da)功(gong)(gong)率(lv)時(shi)(shi)就(jiu)(jiu)會出(chu)(chu)現(xian)各種(zhong)弊端，嚴重時(shi)(shi)直接(jie)損壞功(gong)(gong)率(lv)元件(jian)(jian)(jian)(jian)(jian)。所以(yi)，購(gou)買超(chao)(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)模(mo)(mo)(mo)具時(shi)(shi)不要(yao)(yao)貪圖便宜(yi)，質(zhi)(zhi)量好(hao)的(de)模(mo)(mo)(mo)具才(cai)能(neng)(neng)保證加(jia)工(gong)(gong)產(chan)品的(de)品質(zhi)(zhi)。 3、焊(han)(han)接(jie)時(shi)(shi)熱(re)阻(zu)(zu)要(yao)(yao)達到工(gong)(gong)件(jian)(jian)(jian)(jian)(jian)的(de)熔(rong)點超(chao)(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)換(huan)(huan)能(neng)(neng)器把電能(neng)(neng)轉換(huan)(huan)為(wei)(wei)機(ji)械(xie)振動后(hou)，通(tong)過(guo)(guo)工(gong)(gong)件(jian)(jian)(jian)(jian)(jian)物質(zhi)(zhi)分子(zi)進(jin)行(xing)傳導，超(chao)(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)在固(gu)體中的(de)傳導聲(sheng)(sheng)(sheng)阻(zu)(zu)遠小于在空(kong)氣中的(de)聲(sheng)(sheng)(sheng)阻(zu)(zu)，當(dang)(dang)聲(sheng)(sheng)(sheng)波(bo)通(tong)過(guo)(guo)工(gong)(gong)件(jian)(jian)(jian)(jian)(jian)...
