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

先檢查各連(lian)接(jie)(jie)線是(shi)否有斷路或(huo)短路，連(lian)接(jie)(jie)是(shi)否正(zheng)確(que)，保險是(shi)否完好(hao)，確(que)認無誤后，打(da)開(kai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源，觀察(cha)振(zhen)鏡(jing)驅(qu)(qu)(qu)動板上(shang)的(de)(de)(de)(de)指示燈(deng)(deng)是(shi)否亮(liang)綠(lv)燈(deng)(deng)或(huo)黃燈(deng)(deng)。若(ruo)不(bu)(bu)亮(liang)或(huo)者亮(liang)紅燈(deng)(deng)，則(ze)拔開(kai)驅(qu)(qu)(qu)動板電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源線，用萬(wan)用表測量(liang)其輸(shu)入端各端子(zi)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓是(shi)否為±24V。若(ruo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓正(zheng)常(chang)，側要再測試一(yi)(yi)下帶上(shang)驅(qu)(qu)(qu)動板及機(ji)負(fu)載時，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓是(shi)否正(zheng)常(chang)，如(ru)(ru)果(guo)都不(bu)(bu)正(zheng)常(chang)，則(ze)打(da)開(kai)控制盒，不(bu)(bu)帶負(fu)載測試一(yi)(yi)下開(kai)關(guan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，如(ru)(ru)果(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓不(bu)(bu)正(zheng)常(chang)的(de)(de)(de)(de)話(hua)(hua)，剛(gang)開(kai)關(guan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源損(sun)壞(huai)(huai)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源輸(shu)入正(zheng)常(chang)后，連(lian)好(hao)所有線后，上(shang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)一(yi)(yi)般會發出二(er)聲(sheng)滴答(da)音，若(ruo)沒有響聲(sheng)，再用手手輕(qing)推一(yi)(yi)下振(zhen)鏡(jing)片(pian)，稍有點力度，如(ru)(ru)果(guo)振(zhen)鏡(jing)片(pian)沒自鎖(suo)的(de)(de)(de)(de)話(hua)(hua)，則(ze)驅(qu)(qu)(qu)動板壞(huai)(huai)，當(dang)然電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓輸(shu)出正(zheng)常(chang)的(de)(de)(de)(de)情(qing)況(kuang)下，驅(qu)(qu)(qu)動板燈(deng)(deng)不(bu)(bu)亮(liang)或(huo)者亮(liang)紅燈(deng)(deng)那就(jiu)是(shi)振(zhen)鏡(jing)驅(qu)(qu)(qu)動板或(huo)者電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)有問題，此時找一(yi)(yi)塊確(que)認為完好(hao)的(de)(de)(de)(de)驅(qu)(qu)(qu)動板，正(zheng)確(que)連(lian)接(jie)(jie)后，打(da)開(kai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源，振(zhen)鏡(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)還不(bu)(bu)自鎖(suo)，則(ze)是(shi)振(zhen)鏡(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)損(sun)壞(huai)(huai)，同理，找一(yi)(yi)個確(que)認完好(hao)的(de)(de)(de)(de)振(zhen)鏡(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)，接(jie)(jie)到(dao)不(bu)(bu)上(shang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)驅(qu)(qu)(qu)動板上(shang)，打(da)開(kai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源，若(ruo)不(bu)(bu)上(shang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，振(zhen)鏡(jing)驅(qu)(qu)(qu)動板損(sun)壞(huai)(huai)，如(ru)(ru)此反復的(de)(de)(de)(de)接(jie)(jie)拔線，請務必在斷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)情(qing)況(kuang)下進行的(de)(de)(de)(de)。

2、振鏡電機有自鎖，但不夠力度

用(yong)一塊(kuai)確認完好(hao)(hao)的(de)振鏡驅(qu)動(dong)板和一個完好(hao)(hao)的(de)振鏡電(dian)機，分(fen)別(bie)接在待(dai)測(ce)試的(de)驅(qu)動(dong)板和振鏡頭上，正常通電(dian)，用(yong)手輕(qing)輕(qing)轉動(dong)振鏡軸，若(ruo)變“硬”，則正常；否則，可判定振鏡驅(qu)動(dong)板和振鏡電(dian)機損壞。

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(xin)號(hao)連接線是否連接完好，確認連接無誤后，打標，若仍沒有擺動(dong)(dong)，則(ze)檢(jian)查信(xin)號(hao)線是否正負(fu)接反或者斷線，否則(ze)，則(ze)可斷定驅動(dong)(dong)板損(sun)壞。

4、打標出現波浪線，打標頭機有輕微的叫聲

振(zhen)(zhen)鏡(jing)驅(qu)(qu)動板(ban)發熱量稍高(gao)（出(chu)現干(gan)擾(rao)）檢(jian)查(cha)接(jie)地(di)(di)線(xian)是(shi)否(fou)正(zheng)(zheng)確接(jie)上(shang)（最好(hao)(hao)的(de)(de)(de)接(jie)地(di)(di)方(fang)法(fa)是(shi)：X振(zhen)(zhen)鏡(jing)信(xin)號(hao)地(di)(di)，Y振(zhen)(zhen)鏡(jing)信(xin)號(hao)地(di)(di)，屏蔽線(xian)，220V電(dian)源大地(di)(di)，及打(da)(da)標(biao)(biao)機(ji)殼(ke)要連通(tong)）,若(ruo)(ruo)地(di)(di)線(xian)接(jie)上(shang)后仍有(you)(you)干(gan)擾(rao)，則(ze)首先(xian)檢(jian)查(cha)打(da)(da)標(biao)(biao)卡卡是(shi)否(fou)正(zheng)(zheng)常（檢(jian)查(cha)方(fang)法(fa)是(shi)用一(yi)塊確認(ren)完(wan)好(hao)(hao)的(de)(de)(de)打(da)(da)標(biao)(biao)卡換(huan)上(shang)，打(da)(da)標(biao)(biao)看是(shi)否(fou)仍有(you)(you)干(gan)擾(rao)），若(ruo)(ruo)仍然(ran)有(you)(you)干(gan)擾(rao)，則(ze)進一(yi)步檢(jian)查(cha)振(zhen)(zhen)鏡(jing)電(dian)機(ji)連接(jie)線(xian)是(shi)否(fou)完(wan)好(hao)(hao)，和其(qi)它(ta)線(xian)是(shi)否(fou)有(you)(you)纏繞，若(ruo)(ruo)一(yi)切正(zheng)(zheng)常，則(ze)首先(xian)用一(yi)塊確認(ren)完(wan)好(hao)(hao)的(de)(de)(de)振(zhen)(zhen)鏡(jing)驅(qu)(qu)動板(ban)換(huan)上(shang)，若(ruo)(ruo)沒干(gan)擾(rao)，則(ze)可(ke)斷定振(zhen)(zhen)鏡(jing)驅(qu)(qu)動板(ban)有(you)(you)問題(ti)；若(ruo)(ruo)有(you)(you)干(gan)擾(rao)，則(ze)振(zhen)(zhen)鏡(jing)電(dian)機(ji)有(you)(you)問題(ti)。（當(dang)然(ran)公司(si)外(wai)出(chu)激光維修人員，請確定好(hao)(hao)，如(ru)果客戶的(de)(de)(de)振(zhen)(zhen)鏡(jing)是(shi)三年以前的(de)(de)(de)產(chan)品(pin)，產(chan)品(pin)的(de)(de)(de)抵抗干(gan)擾(rao)能力(li)肯定會差一(yi)點，振(zhen)(zhen)鏡(jing)打(da)(da)標(biao)(biao)頭周邊如(ru)有(you)(you)有(you)(you)手機(ji)信(xin)號(hao)，馬達，電(dian)機(ji)，磁場，又或者是(shi)Q開關的(de)(de)(de)射頻信(xin)號(hao)外(wai)露都有(you)(you)可(ke)能影響，新的(de)(de)(de)振(zhen)(zhen)鏡(jing)都有(you)(you)可(ke)以發生這種(zhong)現象）

5、產生嘯叫

先和(he)第四步(bu)一樣，測試一下打標卡信號，布線，外部(bu)干擾等，如果(guo)還有嘯(xiao)叫，則調(diao)試振(zhen)鏡驅動板的濾波(bo)板上電(dian)位器(qi)，若仍不(bu)能消(xiao)除嘯(xiao)叫，則需要(yao)重新返回(hui)公司做精(jing)密的調(diao)校。（注(zhu)意(yi)：不(bu)能長(chang)時間處于嘯(xiao)叫狀態，以(yi)免會(hui)燒壞振(zhen)鏡電(dian)機）

6、打標里不封口或封口過頭

改變(bian)打標軟(ruan)件中“跳轉延(yan)時”，出光(guang)及關(guan)光(guang)等延(yan)時。若任都不(bu)行，則是(shi)振(zhen)鏡(jing)沒有完全校正好，應該要返回公司，會返回供應商處，有條(tiao)件的激光(guang)維修售后人員可(ke)以按照振(zhen)鏡(jing)調試步(bu)驟(zou)做(zuo)一定的調節，但要注意有幾個電(dian)位器是(shi)不(bu)是(shi)隨(sui)便亂動(dong)的。

7、打標時，打標頭下方，沒有激光輸出，但激光出光孔有激光

軟件打標速(su)度大快，場鏡(jing)沒有安裝，振(zhen)鏡(jing)不動且擺的(de)位置(zhi)不正常，振(zhen)鏡(jing)片(pian)(pian)脫(tuo)落，振(zhen)鏡(jing)片(pian)(pian)臟。前(qian)面(mian)(mian)幾(ji)個問題按上(shang)面(mian)(mian)的(de)方法來處理，振(zhen)鏡(jing)片(pian)(pian)脫(tuo)落裂開(kai)，要返回公司重新換上(shang)新鏡(jing)片(pian)(pian)并調試(shi)好激光，振(zhen)鏡(jing)片(pian)(pian)臟用品99%酒(jiu)精和(he)脫(tuo)脂棉擦試(shi)，如擦拭(shi)不了且是振(zhen)鏡(jing)中心(xin)部(bu)分，或者邊緣部(bu)分大1平(ping)方毫(hao)米則要更換振(zhen)鏡(jing)片(pian)(pian)與振(zhen)鏡(jing)片(pian)(pian)脫(tuo)落一樣處理。

二、如何避免激光振鏡的二次污染

在一般功率輸出(chu)的(de)激光器中，所有的(de)鏡片大都會由于(yu)制造工藝(yi)的(de)原因或受外界污染等(deng)因素導致鏡片對特定(ding)的(de)激光波(bo)長吸收大，久而(er)久之使鏡片壽命縮短，由于(yu)鏡片的(de)損壞而(er)造成影響使用甚至(zhi)停機的(de)情(qing)況時有發生(sheng)。

鏡片(pian)對激光波長(chang)吸收的(de)增(zeng)加會引起不(bu)(bu)均勻加熱導致鏡片(pian)的(de)反(fan)射(she)(she)，折射(she)(she)率產生變(bian)化，激光波長(chang)從高吸收鏡片(pian)上(shang)透過或(huo)反(fan)射(she)(she)時(shi)激光功率的(de)分布不(bu)(bu)均勻使鏡片(pian)中心溫度高，邊緣溫度低，產生這種變(bian)化在光學上(shang)稱透鏡效應(ying)。

由于污(wu)(wu)染(ran)導(dao)致鏡(jing)(jing)(jing)(jing)(jing)片高吸收引發熱透(tou)鏡(jing)(jing)(jing)(jing)(jing)效應(ying)會(hui)產生(sheng)(sheng)許多問題。透(tou)鏡(jing)(jing)(jing)(jing)(jing)基片的(de)(de)不(bu)可逆熱應(ying)力(li)的(de)(de)產生(sheng)(sheng)，光束傳播(bo)通過鏡(jing)(jing)(jing)(jing)(jing)片時所(suo)(suo)產生(sheng)(sheng)的(de)(de)功率損(sun)(sun)耗，聚焦(jiao)光點位置的(de)(de)偏移動，鍍膜(mo)層的(de)(de)過早損(sun)(sun)壞等(deng)都能導(dao)致鏡(jing)(jing)(jing)(jing)(jing)片遭(zao)到破壞。對于暴露在空氣中的(de)(de)鏡(jing)(jing)(jing)(jing)(jing)片，在做清(qing)理(li)時，往(wang)往(wang)不(bu)遵循(xun)對鏡(jing)(jing)(jing)(jing)(jing)片清(qing)理(li)的(de)(de)要求和注意(yi)事項，隨(sui)便取材，其結果將(jiang)造(zao)成新的(de)(de)污(wu)(wu)染(ran)甚至(zhi)劃傷鏡(jing)(jing)(jing)(jing)(jing)片，造(zao)成不(bu)可彌補的(de)(de)損(sun)(sun)失。所(suo)(suo)以根(gen)據多年的(de)(de)經(jing)驗(yan)總結認為(wei)：無論哪一類(lei)光學透(tou)鏡(jing)(jing)(jing)(jing)(jing)保持清(qing)潔(jie)是最重(zhong)要的(de)(de)，要有良好的(de)(de)清(qing)潔(jie)習慣去小心清(qing)洗鏡(jing)(jing)(jing)(jing)(jing)片，就能減少或清(qing)除(chu)有關人為(wei)的(de)(de)原因(yin)所(suo)(suo)造(zao)成污(wu)(wu)染(ran)。

作(zuo)為一條(tiao)常(chang)識，當用手(shou)去操作(zuo)光學系(xi)統時，無論清(qing)(qing)(qing)潔(jie)，拆卸(xie)(xie)，安(an)裝都要(yao)(yao)(yao)帶上指套或醫用手(shou)套，要(yao)(yao)(yao)始終保持(chi)遵循清(qing)(qing)(qing)洗(xi)鏡(jing)(jing)(jing)(jing)片(pian)(pian)(pian)(pian)的(de)要(yao)(yao)(yao)求及注意事項，在清(qing)(qing)(qing)潔(jie)過程中，只能用規定(ding)的(de)材料，如光學用的(de)擦鏡(jing)(jing)(jing)(jing)紙，棉(mian)簽，試(shi)劑級乙(yi)醇。對(dui)(dui)任何鏡(jing)(jing)(jing)(jing)片(pian)(pian)(pian)(pian)的(de)清(qing)(qing)(qing)潔(jie)，拆卸(xie)(xie)，安(an)裝走(zou)捷徑都將(jiang)導致鏡(jing)(jing)(jing)(jing)片(pian)(pian)(pian)(pian)壽命縮短，甚至(zhi)永久性地損(sun)壞(huai)。所以(yi)，要(yao)(yao)(yao)用普通的(de)常(chang)識來防止(zhi)鏡(jing)(jing)(jing)(jing)片(pian)(pian)(pian)(pian)受其(qi)(qi)它原因的(de)污(wu)染(ran)，如遇(yu)防潮濕(shi)、煙(yan)霧(wu)、防塵(chen)等(deng)(deng)等(deng)(deng)。在確定(ding)某一鏡(jing)(jing)(jing)(jing)片(pian)(pian)(pian)(pian)污(wu)染(ran)后，要(yao)(yao)(yao)用洗(xi)耳球(qiu)吹鏡(jing)(jing)(jing)(jing)片(pian)(pian)(pian)(pian)，直到其(qi)(qi)表面(mian)沒有微粒為佳，千萬不要(yao)(yao)(yao)用嘴去吹。因為吹出的(de)空氣大都含油、水等(deng)(deng)將(jiang)會(hui)進一步(bu)污(wu)染(ran)鏡(jing)(jing)(jing)(jing)片(pian)(pian)(pian)(pian)。如果經過洗(xi)耳球(qiu)處理以(yi)后其(qi)(qi)表面(mian)仍有污(wu)染(ran)存在，就必須用專(zhuan)用的(de)棉(mian)簽蘸實驗室級丙酮，乙(yi)醇來輕輕擦拭。這樣(yang)就可以(yi)清(qing)(qing)(qing)除大多數污(wu)染(ran)薄層。激光器(qi)中的(de)鏡(jing)(jing)(jing)(jing)片(pian)(pian)(pian)(pian)的(de)污(wu)染(ran)會(hui)對(dui)(dui)激光輸出乃至(zhi)數據采集系(xi)統造成嚴(yan)重(zhong)的(de)采集錯誤，如果我們能夠使鏡(jing)(jing)(jing)(jing)片(pian)(pian)(pian)(pian)經常(chang)保持(chi)清(qing)(qing)(qing)潔(jie)，將(jiang)會(hui)延(yan)長整(zheng)機的(de)使用壽命。
