在(zai)進行超(chao)(chao)聲(sheng)波(bo)(bo)(bo)焊(han)(han)(han)接(jie)(jie)時(shi)(shi)，使(shi)用多大(da)振蕩頻率(lv)(lv)、輸(shu)出功率(lv)(lv)及振幅范圍等，要(yao)(yao)根據工(gong)(gong)(gong)件(jian)的(de)(de)焊(han)(han)(han)線(xian)面積、材(cai)料(liao)(liao)、工(gong)(gong)(gong)件(jian)內是(shi)(shi)(shi)(shi)否(fou)氣密有(you)(you)電(dian)子，是(shi)(shi)(shi)(shi)否(fou)元器件(jian)等因素(su)來(lai)(lai)決定。認為(wei)功率(lv)(lv)越大(da)越好(hao)，這是(shi)(shi)(shi)(shi)一(yi)個誤(wu)解。如(ru)果(guo)對(dui)超(chao)(chao)聲(sheng)波(bo)(bo)(bo)相(xiang)關技術不(bu)(bu)(bu)是(shi)(shi)(shi)(shi)很了解，最好(hao)請教(jiao)超(chao)(chao)聲(sheng)波(bo)(bo)(bo)焊(han)(han)(han)接(jie)(jie)機生產(chan)廠家的(de)(de)技術人員。下面固(gu)特(te)超(chao)(chao)聲(sheng)簡單介紹(shao)下超(chao)(chao)聲(sheng)波(bo)(bo)(bo)焊(han)(han)(han)接(jie)(jie)時(shi)(shi)需要(yao)(yao)注意的(de)(de)幾(ji)個要(yao)(yao)點(dian)，希望對(dui)您(nin)有(you)(you)幫助。 1、焊(han)(han)(han)接(jie)(jie)時(shi)(shi)兩種工(gong)(gong)(gong)件(jian)的(de)(de)可(ke)焊(han)(han)(han)接(jie)(jie)性不(bu)(bu)(bu)同(tong)材(cai)質(zhi)之間(jian)(jian)有(you)(you)的(de)(de)能(neng)更好(hao)地(di)熔接(jie)(jie)，有(you)(you)的(de)(de)是(shi)(shi)(shi)(shi)基本(ben)可(ke)相(xiang)熔，有(you)(you)的(de)(de)是(shi)(shi)(shi)(shi)不(bu)(bu)(bu)相(xiang)熔的(de)(de)。同(tong)一(yi)材(cai)料(liao)(liao)從原(yuan)理上來(lai)(lai)講是(shi)(shi)(shi)(shi)可(ke)以焊(han)(han)(han)接(jie)(jie)的(de)(de)，但是(shi)(shi)(shi)(shi)當(dang)要(yao)(yao)焊(han)(han)(han)接(jie)(jie)的(de)(de)工(gong)(gong)(gong)件(jian)的(de)(de)熔點(dian)大(da)于350℃時(shi)(shi)，就不(bu)(bu)(bu)適(shi)合用超(chao)(chao)聲(sheng)波(bo)(bo)(bo)焊(han)(han)(han)接(jie)(jie)了。因為(wei)超(chao)(chao)聲(sheng)波(bo)(bo)(bo)是(shi)(shi)(shi)(shi)瞬(shun)間(jian)(jian)使(shi)工(gong)(gong)(gong)件(jian)分(fen)子溶化，最好(hao)是(shi)(shi)(shi)(shi)在(zai)3秒之內。如(ru)果(guo)超(chao)(chao)過(guo)(guo)3秒，不(bu)(bu)(bu)能(neng)良好(hao)熔接(jie)(jie)，就需要(yao)(yao)選(xuan)擇其它焊(han)(han)(han)接(jie)(jie)工(gong)(gong)(gong)藝。一(yi)般(ban)來(lai)(lai)講ABS材(cai)質(zhi)是(shi)(shi)(shi)(shi)最容易(yi)焊(han)(han)(han)接(jie)(jie)，尼龍(long)或(huo)PP料(liao)(liao)是(shi)(shi)(shi)(shi)一(yi)般(ban)可(ke)焊(han)(han)(han)接(jie)(jie)的(de)(de)。 2、焊(han)(han)(han)模(mo)結構需要(yao)(yao)嚴(yan)格檢驗正規超(chao)(chao)聲(sheng)波(bo)(bo)(bo)模(mo)生產(chan)進料(liao)(liao)都有(you)(you)一(yi)套嚴(yan)格的(de)(de)檢驗程序(xu)，加(jia)(jia)工(gong)(gong)(gong)尺寸(cun)都是(shi)(shi)(shi)(shi)經過(guo)(guo)計算機軟件(jian)模(mo)擬(ni)和校驗后加(jia)(jia)工(gong)(gong)(gong)出來(lai)(lai)的(de)(de)，品(pin)質(zhi)才有(you)(you)保障(zhang)。這些工(gong)(gong)(gong)序(xu)一(yi)般(ban)作(zuo)坊(fang)是(shi)(shi)(shi)(shi)無法做(zuo)到(dao)的(de)(de)，如(ru)不(bu)(bu)(bu)經過(guo)(guo)合理地(di)設計，做(zuo)出的(de)(de)模(mo)具，在(zai)焊(han)(han)(han)接(jie)(jie)小工(gong)(gong)(gong)件(jian)時(shi)(shi)，反(fan)應問(wen)題還(huan)不(bu)(bu)(bu)明顯，當(dang)大(da)功率(lv)(lv)時(shi)(shi)就會出現各種弊端，嚴(yan)重(zhong)時(shi)(shi)直接(jie)(jie)損壞功率(lv)(lv)元件(jian)。所以，購買超(chao)(chao)聲(sheng)波(bo)(bo)(bo)模(mo)具時(shi)(shi)不(bu)(bu)(bu)要(yao)(yao)貪(tan)圖(tu)便(bian)宜，質(zhi)量好(hao)的(de)(de)模(mo)具才能(neng)保證加(jia)(jia)工(gong)(gong)(gong)產(chan)品(pin)的(de)(de)品(pin)質(zhi)。 3、焊(han)(han)(han)接(jie)(jie)時(shi)(shi)熱阻要(yao)(yao)達到(dao)工(gong)(gong)(gong)件(jian)的(de)(de)熔點(dian)超(chao)(chao)聲(sheng)波(bo)(bo)(bo)換(huan)能(neng)器把電(dian)能(neng)轉(zhuan)換(huan)為(wei)機械振動(dong)后，通(tong)過(guo)(guo)工(gong)(gong)(gong)件(jian)物質(zhi)分(fen)子進行傳導，超(chao)(chao)聲(sheng)波(bo)(bo)(bo)在(zai)固(gu)體中的(de)(de)傳導聲(sheng)阻遠小于在(zai)空氣中的(de)(de)聲(sheng)阻，當(dang)聲(sheng)波(bo)(bo)(bo)通(tong)過(guo)(guo)工(gong)(gong)(gong)件(jian)...
