超聲波焊接原理簡介

　　超聲波焊接原理簡介

超聲波焊接是通過超聲波產生器將50/60赫茲電流轉化成15、20、30或40 KHz 電(dian)能(neng)。被(bei)轉(zhuan)化(hua)的(de)高(gao)頻(pin)電(dian)能(neng)通(tong)過(guo)換(huan)能(neng)器(qi)再(zai)次(ci)被(bei)轉(zhuan)化(hua)成(cheng)為(wei)同(tong)等(deng)頻(pin)率(lv)的(de)機(ji)械(xie)運(yun)動(dong)，隨(sui)後(hou)機(ji)械(xie)運(yun)動(dong)通(tong)過(guo)一(yi)套(tao)可(ke)以(yi)改(gai)動(dong)振(zhen)幅(fu)的(de)變(bian)幅(fu)杆(gan)裝(zhuang)置(zhi)傳(chuan)遞(di)到(dao)焊(han)頭(tou)。焊(han)頭(tou)將(jiang)接(jie)收(shou)到(dao)的(de)振(zhen)動(dong)能(neng)量(liang)傳(chuan)遞(di)到(dao)待(dai)焊(han)接(jie)工(gong)件(jian)的(de)接(jie)合(he)部(bu)，在(zai)該(gai)區(qu)域(yu)
