一、激光打標機振鏡方面常見的故障及解決方法有哪些

1、振鏡電機不自鎖

先檢(jian)查(cha)各連(lian)接線(xian)是(shi)否(fou)有(you)斷(duan)路(lu)或(huo)(huo)短路(lu)，連(lian)接是(shi)否(fou)正(zheng)確，保險是(shi)否(fou)完(wan)(wan)好，確認(ren)(ren)無誤后(hou)，打開(kai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)，觀察振(zhen)(zhen)(zhen)鏡(jing)(jing)(jing)驅(qu)動(dong)板上(shang)(shang)(shang)(shang)的指示燈(deng)是(shi)否(fou)亮(liang)綠(lv)燈(deng)或(huo)(huo)黃燈(deng)。若(ruo)不(bu)(bu)(bu)(bu)亮(liang)或(huo)(huo)者(zhe)亮(liang)紅(hong)燈(deng)，則拔開(kai)驅(qu)動(dong)板電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)線(xian)，用(yong)(yong)(yong)萬用(yong)(yong)(yong)表測(ce)(ce)量其(qi)輸入端(duan)各端(duan)子(zi)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)是(shi)否(fou)為(wei)±24V。若(ruo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)正(zheng)常(chang)(chang)，側要再測(ce)(ce)試(shi)一(yi)下帶上(shang)(shang)(shang)(shang)驅(qu)動(dong)板及機負載時，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)是(shi)否(fou)正(zheng)常(chang)(chang)，如(ru)果(guo)都(dou)不(bu)(bu)(bu)(bu)正(zheng)常(chang)(chang)，則打開(kai)控制盒，不(bu)(bu)(bu)(bu)帶負載測(ce)(ce)試(shi)一(yi)下開(kai)關電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，如(ru)果(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)不(bu)(bu)(bu)(bu)正(zheng)常(chang)(chang)的話(hua)，剛開(kai)關電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)損壞(huai)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)輸入正(zheng)常(chang)(chang)后(hou)，連(lian)好所有(you)線(xian)后(hou)，上(shang)(shang)(shang)(shang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機一(yi)般會(hui)發出二(er)聲(sheng)滴答音(yin)，若(ruo)沒有(you)響(xiang)聲(sheng)，再用(yong)(yong)(yong)手(shou)手(shou)輕推一(yi)下振(zhen)(zhen)(zhen)鏡(jing)(jing)(jing)片(pian)，稍(shao)有(you)點力(li)度(du)，如(ru)果(guo)振(zhen)(zhen)(zhen)鏡(jing)(jing)(jing)片(pian)沒自鎖(suo)的話(hua)，則驅(qu)動(dong)板壞(huai)，當然電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)輸出正(zheng)常(chang)(chang)的情況(kuang)(kuang)下，驅(qu)動(dong)板燈(deng)不(bu)(bu)(bu)(bu)亮(liang)或(huo)(huo)者(zhe)亮(liang)紅(hong)燈(deng)那就是(shi)振(zhen)(zhen)(zhen)鏡(jing)(jing)(jing)驅(qu)動(dong)板或(huo)(huo)者(zhe)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機有(you)問題(ti)，此時找一(yi)塊確認(ren)(ren)為(wei)完(wan)(wan)好的驅(qu)動(dong)板，正(zheng)確連(lian)接后(hou)，打開(kai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)，振(zhen)(zhen)(zhen)鏡(jing)(jing)(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機還不(bu)(bu)(bu)(bu)自鎖(suo)，則是(shi)振(zhen)(zhen)(zhen)鏡(jing)(jing)(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機損壞(huai)，同(tong)理，找一(yi)個確認(ren)(ren)完(wan)(wan)好的振(zhen)(zhen)(zhen)鏡(jing)(jing)(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機，接到不(bu)(bu)(bu)(bu)上(shang)(shang)(shang)(shang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的驅(qu)動(dong)板上(shang)(shang)(shang)(shang)，打開(kai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)，若(ruo)不(bu)(bu)(bu)(bu)上(shang)(shang)(shang)(shang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，振(zhen)(zhen)(zhen)鏡(jing)(jing)(jing)驅(qu)動(dong)板損壞(huai)，如(ru)此反復的接拔線(xian)，請務(wu)必在斷(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的情況(kuang)(kuang)下進(jin)行的。

2、振鏡電機有自鎖，但不夠力度

用一塊確認完好(hao)的振鏡(jing)(jing)(jing)驅(qu)動(dong)板和(he)一個完好(hao)的振鏡(jing)(jing)(jing)電(dian)機，分(fen)別(bie)接在待測試的驅(qu)動(dong)板和(he)振鏡(jing)(jing)(jing)頭上，正常通電(dian)，用手(shou)輕(qing)輕(qing)轉動(dong)振鏡(jing)(jing)(jing)軸，若變“硬”，則(ze)正常；否則(ze)，可判(pan)定(ding)振鏡(jing)(jing)(jing)驅(qu)動(dong)板和(he)振鏡(jing)(jing)(jing)電(dian)機損(sun)壞(huai)。

3、振鏡電機不擺動

檢查打標卡是否有控制信號輸出，（注意其信號為-5V到+5V的直流電壓信號）若有，則檢查振鏡信號連接(jie)線是否連接(jie)完好，確認連接(jie)無誤后(hou)，打標，若仍(reng)沒有擺動，則(ze)檢查(cha)信號線是否正負接(jie)反或者斷(duan)線，否則(ze)，則(ze)可斷(duan)定驅動板損壞(huai)。

4、打標出現波浪線，打標頭機有輕微的叫聲

振鏡驅動(dong)(dong)板發熱量(liang)稍高（出(chu)現(xian)干(gan)擾(rao)）檢(jian)查接地(di)線是(shi)(shi)否(fou)正(zheng)確(que)接上(shang)（最好的接地(di)方(fang)法(fa)是(shi)(shi)：X振鏡信號(hao)地(di)，Y振鏡信號(hao)地(di)，屏蔽線，220V電(dian)源大地(di)，及打標(biao)(biao)(biao)機(ji)殼要(yao)連通）,若地(di)線接上(shang)后(hou)仍(reng)(reng)有(you)(you)干(gan)擾(rao)，則(ze)首(shou)先檢(jian)查打標(biao)(biao)(biao)卡(ka)卡(ka)是(shi)(shi)否(fou)正(zheng)常（檢(jian)查方(fang)法(fa)是(shi)(shi)用(yong)一(yi)(yi)塊(kuai)確(que)認(ren)完好的打標(biao)(biao)(biao)卡(ka)換上(shang)，打標(biao)(biao)(biao)看是(shi)(shi)否(fou)仍(reng)(reng)有(you)(you)干(gan)擾(rao)），若仍(reng)(reng)然有(you)(you)干(gan)擾(rao)，則(ze)進一(yi)(yi)步檢(jian)查振鏡電(dian)機(ji)連接線是(shi)(shi)否(fou)完好，和其它線是(shi)(shi)否(fou)有(you)(you)纏(chan)繞，若一(yi)(yi)切正(zheng)常，則(ze)首(shou)先用(yong)一(yi)(yi)塊(kuai)確(que)認(ren)完好的振鏡驅動(dong)(dong)板換上(shang)，若沒干(gan)擾(rao)，則(ze)可(ke)斷定(ding)振鏡驅動(dong)(dong)板有(you)(you)問題；若有(you)(you)干(gan)擾(rao)，則(ze)振鏡電(dian)機(ji)有(you)(you)問題。（當然公司(si)外(wai)出(chu)激光維修人員(yuan)，請確(que)定(ding)好，如(ru)果客戶的振鏡是(shi)(shi)三年以前的產(chan)品(pin)，產(chan)品(pin)的抵抗(kang)干(gan)擾(rao)能力肯定(ding)會(hui)差(cha)一(yi)(yi)點，振鏡打標(biao)(biao)(biao)頭(tou)周邊(bian)如(ru)有(you)(you)有(you)(you)手機(ji)信號(hao)，馬達，電(dian)機(ji)，磁場，又(you)或者是(shi)(shi)Q開關(guan)的射頻信號(hao)外(wai)露都(dou)有(you)(you)可(ke)能影(ying)響(xiang)，新的振鏡都(dou)有(you)(you)可(ke)以發生這種現(xian)象）

5、產生嘯叫

先和第(di)四步一樣(yang)，測試一下(xia)打標卡信號，布(bu)線(xian)，外部干擾等，如(ru)果還(huan)有(you)嘯(xiao)叫(jiao)，則調(diao)試振鏡(jing)驅動板的(de)濾波板上電位器，若(ruo)仍(reng)不能(neng)消除嘯(xiao)叫(jiao)，則需要重新返(fan)回公司做精密的(de)調(diao)校。（注意：不能(neng)長時間處于嘯(xiao)叫(jiao)狀態，以免會(hui)燒壞(huai)振鏡(jing)電機）

6、打標里不封口或封口過頭

改變打標軟件(jian)(jian)中“跳(tiao)轉延(yan)時(shi)(shi)”，出光及關光等延(yan)時(shi)(shi)。若(ruo)任(ren)都不(bu)行，則是振鏡沒有完全校正好，應該要返(fan)回公司(si)，會返(fan)回供應商處，有條件(jian)(jian)的(de)激光維修售(shou)后(hou)人員可以按照振鏡調(diao)(diao)試步驟做一定的(de)調(diao)(diao)節，但要注意(yi)有幾(ji)個電位(wei)器是不(bu)是隨便(bian)亂(luan)動的(de)。

7、打標時，打標頭下方，沒有激光輸出，但激光出光孔有激光

軟件(jian)打標(biao)速(su)度大快(kuai)，場鏡(jing)(jing)(jing)沒有安裝，振(zhen)鏡(jing)(jing)(jing)不動且(qie)擺(bai)的位置不正常，振(zhen)鏡(jing)(jing)(jing)片(pian)脫(tuo)落(luo)，振(zhen)鏡(jing)(jing)(jing)片(pian)臟。前面(mian)幾(ji)個(ge)問(wen)題按上(shang)面(mian)的方法來(lai)處(chu)理，振(zhen)鏡(jing)(jing)(jing)片(pian)脫(tuo)落(luo)裂開，要(yao)返回(hui)公(gong)司重(zhong)新(xin)換上(shang)新(xin)鏡(jing)(jing)(jing)片(pian)并調試好激光，振(zhen)鏡(jing)(jing)(jing)片(pian)臟用品(pin)99%酒(jiu)精(jing)和脫(tuo)脂(zhi)棉擦試，如擦拭(shi)不了(le)且(qie)是(shi)振(zhen)鏡(jing)(jing)(jing)中心部分，或(huo)者邊緣部分大1平方毫米(mi)則要(yao)更換振(zhen)鏡(jing)(jing)(jing)片(pian)與振(zhen)鏡(jing)(jing)(jing)片(pian)脫(tuo)落(luo)一樣處(chu)理。

二、如何避免激光振鏡的二次污染

在一般功(gong)率輸(shu)出(chu)的激光器中，所有的鏡(jing)片(pian)大都會(hui)由(you)于制造工(gong)藝的原因或受外界污染等(deng)因素導致(zhi)鏡(jing)片(pian)對(dui)特定的激光波長吸收大，久而久之使鏡(jing)片(pian)壽命縮短，由(you)于鏡(jing)片(pian)的損壞而造成影響使用甚至停機的情況(kuang)時(shi)有發生。

鏡(jing)片(pian)(pian)對激光波長(chang)吸(xi)(xi)收(shou)的增加(jia)會(hui)引起不均勻加(jia)熱導致(zhi)鏡(jing)片(pian)(pian)的反射(she)，折射(she)率(lv)產(chan)生變化，激光波長(chang)從高吸(xi)(xi)收(shou)鏡(jing)片(pian)(pian)上(shang)透過或反射(she)時激光功率(lv)的分(fen)布不均勻使鏡(jing)片(pian)(pian)中心溫(wen)度高，邊(bian)緣(yuan)溫(wen)度低，產(chan)生這種變化在(zai)光學上(shang)稱透鏡(jing)效應。

由于(yu)污(wu)染(ran)導致鏡(jing)片(pian)高吸收(shou)引發熱透鏡(jing)效應(ying)會(hui)產生(sheng)(sheng)許多(duo)問(wen)題。透鏡(jing)基片(pian)的(de)(de)(de)(de)(de)不可(ke)逆熱應(ying)力的(de)(de)(de)(de)(de)產生(sheng)(sheng)，光(guang)束傳播(bo)通過鏡(jing)片(pian)時所(suo)產生(sheng)(sheng)的(de)(de)(de)(de)(de)功率(lv)損耗，聚焦(jiao)光(guang)點位置的(de)(de)(de)(de)(de)偏移動，鍍膜層(ceng)的(de)(de)(de)(de)(de)過早損壞(huai)等都能導致鏡(jing)片(pian)遭到破壞(huai)。對于(yu)暴露在空氣中的(de)(de)(de)(de)(de)鏡(jing)片(pian)，在做清(qing)(qing)理(li)時，往(wang)往(wang)不遵循對鏡(jing)片(pian)清(qing)(qing)理(li)的(de)(de)(de)(de)(de)要求和注(zhu)意(yi)事項，隨便(bian)取材，其結果將造(zao)成新的(de)(de)(de)(de)(de)污(wu)染(ran)甚至劃傷鏡(jing)片(pian)，造(zao)成不可(ke)彌補的(de)(de)(de)(de)(de)損失(shi)。所(suo)以根據多(duo)年(nian)的(de)(de)(de)(de)(de)經驗總結認(ren)為(wei)：無論哪一類光(guang)學透鏡(jing)保持清(qing)(qing)潔(jie)是最重要的(de)(de)(de)(de)(de)，要有(you)良好的(de)(de)(de)(de)(de)清(qing)(qing)潔(jie)習慣去小(xiao)心清(qing)(qing)洗鏡(jing)片(pian)，就能減少(shao)或清(qing)(qing)除有(you)關(guan)人為(wei)的(de)(de)(de)(de)(de)原因所(suo)造(zao)成污(wu)染(ran)。

作為一(yi)條常識(shi)(shi)，當用(yong)(yong)手(shou)去操作光學系(xi)統時(shi)，無論(lun)清(qing)(qing)潔，拆(chai)卸，安裝都要帶(dai)上(shang)指套(tao)(tao)或醫用(yong)(yong)手(shou)套(tao)(tao)，要始終保(bao)持(chi)遵循清(qing)(qing)洗鏡片(pian)的(de)(de)(de)(de)要求(qiu)及(ji)注意事項，在(zai)(zai)清(qing)(qing)潔過(guo)程中，只能用(yong)(yong)規定(ding)的(de)(de)(de)(de)材料(liao)，如(ru)光學用(yong)(yong)的(de)(de)(de)(de)擦鏡紙(zhi)，棉簽，試劑級乙醇(chun)。對任何鏡片(pian)的(de)(de)(de)(de)清(qing)(qing)潔，拆(chai)卸，安裝走捷徑都將導致鏡片(pian)壽命(ming)縮短，甚至永(yong)久性地損壞。所以(yi)，要用(yong)(yong)普通的(de)(de)(de)(de)常識(shi)(shi)來防(fang)止鏡片(pian)受其(qi)它(ta)原因(yin)(yin)的(de)(de)(de)(de)污(wu)(wu)染，如(ru)遇防(fang)潮濕、煙霧、防(fang)塵等(deng)等(deng)。在(zai)(zai)確定(ding)某一(yi)鏡片(pian)污(wu)(wu)染后(hou)，要用(yong)(yong)洗耳球吹(chui)鏡片(pian)，直(zhi)到其(qi)表(biao)面沒有微粒為佳(jia)，千(qian)萬不要用(yong)(yong)嘴去吹(chui)。因(yin)(yin)為吹(chui)出(chu)的(de)(de)(de)(de)空氣大都含(han)油、水等(deng)將會(hui)進一(yi)步污(wu)(wu)染鏡片(pian)。如(ru)果(guo)經(jing)過(guo)洗耳球處理(li)以(yi)后(hou)其(qi)表(biao)面仍有污(wu)(wu)染存在(zai)(zai)，就必須用(yong)(yong)專(zhuan)用(yong)(yong)的(de)(de)(de)(de)棉簽蘸實驗室級丙酮(tong)，乙醇(chun)來輕(qing)輕(qing)擦拭(shi)。這樣就可以(yi)清(qing)(qing)除大多(duo)數(shu)污(wu)(wu)染薄(bo)層。激光器中的(de)(de)(de)(de)鏡片(pian)的(de)(de)(de)(de)污(wu)(wu)染會(hui)對激光輸出(chu)乃至數(shu)據采集系(xi)統造成嚴重的(de)(de)(de)(de)采集錯誤，如(ru)果(guo)我們能夠使鏡片(pian)經(jing)常保(bao)持(chi)清(qing)(qing)潔，將會(hui)延長整機的(de)(de)(de)(de)使用(yong)(yong)壽命(ming)。
