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)線(xian)是(shi)(shi)否有(you)(you)斷路(lu)或(huo)短(duan)路(lu)，連(lian)接(jie)是(shi)(shi)否正(zheng)(zheng)確(que)(que)(que)，保險是(shi)(shi)否完好(hao)，確(que)(que)(que)認(ren)無誤(wu)后(hou)(hou)，打(da)開(kai)(kai)(kai)電(dian)(dian)(dian)(dian)(dian)源(yuan)，觀(guan)察振(zhen)(zhen)鏡(jing)(jing)驅(qu)(qu)(qu)(qu)動(dong)(dong)板(ban)(ban)(ban)上(shang)的(de)(de)指示(shi)燈(deng)是(shi)(shi)否亮(liang)綠燈(deng)或(huo)黃燈(deng)。若(ruo)不(bu)(bu)亮(liang)或(huo)者亮(liang)紅(hong)燈(deng)，則(ze)拔開(kai)(kai)(kai)驅(qu)(qu)(qu)(qu)動(dong)(dong)板(ban)(ban)(ban)電(dian)(dian)(dian)(dian)(dian)源(yuan)線(xian)，用萬用表測(ce)(ce)(ce)量其(qi)輸入(ru)端各端子的(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)是(shi)(shi)否為±24V。若(ruo)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)正(zheng)(zheng)常，側要再(zai)(zai)測(ce)(ce)(ce)試一下帶上(shang)驅(qu)(qu)(qu)(qu)動(dong)(dong)板(ban)(ban)(ban)及機(ji)(ji)負(fu)載時(shi)，電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)是(shi)(shi)否正(zheng)(zheng)常，如(ru)果(guo)都不(bu)(bu)正(zheng)(zheng)常，則(ze)打(da)開(kai)(kai)(kai)控制(zhi)盒(he)，不(bu)(bu)帶負(fu)載測(ce)(ce)(ce)試一下開(kai)(kai)(kai)關(guan)(guan)電(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，如(ru)果(guo)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)不(bu)(bu)正(zheng)(zheng)常的(de)(de)話(hua)，剛開(kai)(kai)(kai)關(guan)(guan)電(dian)(dian)(dian)(dian)(dian)源(yuan)損(sun)(sun)壞。電(dian)(dian)(dian)(dian)(dian)源(yuan)輸入(ru)正(zheng)(zheng)常后(hou)(hou)，連(lian)好(hao)所有(you)(you)線(xian)后(hou)(hou)，上(shang)電(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)一般(ban)會發出二(er)聲滴答音，若(ruo)沒(mei)有(you)(you)響聲，再(zai)(zai)用手(shou)手(shou)輕(qing)推一下振(zhen)(zhen)鏡(jing)(jing)片，稍有(you)(you)點力度，如(ru)果(guo)振(zhen)(zhen)鏡(jing)(jing)片沒(mei)自鎖(suo)的(de)(de)話(hua)，則(ze)驅(qu)(qu)(qu)(qu)動(dong)(dong)板(ban)(ban)(ban)壞，當(dang)然(ran)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)輸出正(zheng)(zheng)常的(de)(de)情況下，驅(qu)(qu)(qu)(qu)動(dong)(dong)板(ban)(ban)(ban)燈(deng)不(bu)(bu)亮(liang)或(huo)者亮(liang)紅(hong)燈(deng)那就是(shi)(shi)振(zhen)(zhen)鏡(jing)(jing)驅(qu)(qu)(qu)(qu)動(dong)(dong)板(ban)(ban)(ban)或(huo)者電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)有(you)(you)問題，此時(shi)找(zhao)一塊確(que)(que)(que)認(ren)為完好(hao)的(de)(de)驅(qu)(qu)(qu)(qu)動(dong)(dong)板(ban)(ban)(ban)，正(zheng)(zheng)確(que)(que)(que)連(lian)接(jie)后(hou)(hou)，打(da)開(kai)(kai)(kai)電(dian)(dian)(dian)(dian)(dian)源(yuan)，振(zhen)(zhen)鏡(jing)(jing)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)還(huan)不(bu)(bu)自鎖(suo)，則(ze)是(shi)(shi)振(zhen)(zhen)鏡(jing)(jing)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)損(sun)(sun)壞，同理，找(zhao)一個確(que)(que)(que)認(ren)完好(hao)的(de)(de)振(zhen)(zhen)鏡(jing)(jing)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)，接(jie)到不(bu)(bu)上(shang)電(dian)(dian)(dian)(dian)(dian)的(de)(de)驅(qu)(qu)(qu)(qu)動(dong)(dong)板(ban)(ban)(ban)上(shang)，打(da)開(kai)(kai)(kai)電(dian)(dian)(dian)(dian)(dian)源(yuan)，若(ruo)不(bu)(bu)上(shang)電(dian)(dian)(dian)(dian)(dian)，振(zhen)(zhen)鏡(jing)(jing)驅(qu)(qu)(qu)(qu)動(dong)(dong)板(ban)(ban)(ban)損(sun)(sun)壞，如(ru)此反(fan)復的(de)(de)接(jie)拔線(xian)，請務必在斷電(dian)(dian)(dian)(dian)(dian)的(de)(de)情況下進行的(de)(de)。

2、振鏡電機有自鎖，但不夠力度

用一(yi)塊確認完好(hao)的(de)振(zhen)鏡(jing)(jing)(jing)驅(qu)動(dong)(dong)板(ban)和(he)一(yi)個完好(hao)的(de)振(zhen)鏡(jing)(jing)(jing)電機(ji)，分(fen)別接在待(dai)測試的(de)驅(qu)動(dong)(dong)板(ban)和(he)振(zhen)鏡(jing)(jing)(jing)頭上，正(zheng)常通電，用手輕輕轉(zhuan)動(dong)(dong)振(zhen)鏡(jing)(jing)(jing)軸(zhou)，若變(bian)“硬”，則正(zheng)常；否則，可判定(ding)振(zhen)鏡(jing)(jing)(jing)驅(qu)動(dong)(dong)板(ban)和(he)振(zhen)鏡(jing)(jing)(jing)電機(ji)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)號連接線(xian)是否(fou)(fou)連接完好，確認連接無誤(wu)后，打標，若仍沒有(you)擺動，則檢查信(xin)號線(xian)是否(fou)(fou)正負(fu)接反或者斷線(xian)，否(fou)(fou)則，則可斷定(ding)驅(qu)動板損(sun)壞。

4、打標出現波浪線，打標頭機有輕微的叫聲

振(zhen)鏡(jing)(jing)(jing)驅(qu)(qu)動板(ban)(ban)發(fa)熱量(liang)稍高（出(chu)現(xian)干(gan)(gan)擾(rao)）檢(jian)(jian)查接(jie)地(di)(di)線(xian)是否正(zheng)確(que)接(jie)上(shang)（最好(hao)的(de)接(jie)地(di)(di)方法是：X振(zhen)鏡(jing)(jing)(jing)信號地(di)(di)，Y振(zhen)鏡(jing)(jing)(jing)信號地(di)(di)，屏蔽線(xian)，220V電(dian)源大(da)地(di)(di)，及打標機殼要連通）,若地(di)(di)線(xian)接(jie)上(shang)后仍(reng)有(you)(you)(you)干(gan)(gan)擾(rao)，則(ze)首先(xian)檢(jian)(jian)查打標卡(ka)(ka)卡(ka)(ka)是否正(zheng)常（檢(jian)(jian)查方法是用一(yi)塊確(que)認完好(hao)的(de)打標卡(ka)(ka)換上(shang)，打標看是否仍(reng)有(you)(you)(you)干(gan)(gan)擾(rao)），若仍(reng)然有(you)(you)(you)干(gan)(gan)擾(rao)，則(ze)進一(yi)步檢(jian)(jian)查振(zhen)鏡(jing)(jing)(jing)電(dian)機連接(jie)線(xian)是否完好(hao)，和其它線(xian)是否有(you)(you)(you)纏繞，若一(yi)切(qie)正(zheng)常，則(ze)首先(xian)用一(yi)塊確(que)認完好(hao)的(de)振(zhen)鏡(jing)(jing)(jing)驅(qu)(qu)動板(ban)(ban)換上(shang)，若沒干(gan)(gan)擾(rao)，則(ze)可(ke)斷定振(zhen)鏡(jing)(jing)(jing)驅(qu)(qu)動板(ban)(ban)有(you)(you)(you)問題(ti)；若有(you)(you)(you)干(gan)(gan)擾(rao)，則(ze)振(zhen)鏡(jing)(jing)(jing)電(dian)機有(you)(you)(you)問題(ti)。（當(dang)然公司外出(chu)激光(guang)維修人員，請(qing)確(que)定好(hao)，如(ru)果客戶的(de)振(zhen)鏡(jing)(jing)(jing)是三(san)年以(yi)前的(de)產品(pin)，產品(pin)的(de)抵抗干(gan)(gan)擾(rao)能力肯定會(hui)差一(yi)點，振(zhen)鏡(jing)(jing)(jing)打標頭周邊如(ru)有(you)(you)(you)有(you)(you)(you)手機信號，馬達，電(dian)機，磁(ci)場(chang)，又或者是Q開關(guan)的(de)射頻(pin)信號外露都(dou)有(you)(you)(you)可(ke)能影響，新的(de)振(zhen)鏡(jing)(jing)(jing)都(dou)有(you)(you)(you)可(ke)以(yi)發(fa)生這種現(xian)象(xiang)）

5、產生嘯叫

先和第四步一(yi)(yi)樣，測試一(yi)(yi)下打標卡信(xin)號(hao)，布線(xian)，外(wai)部(bu)干擾等(deng)，如(ru)果還有嘯(xiao)(xiao)叫，則調試振鏡(jing)(jing)驅動板(ban)的濾波板(ban)上電位(wei)器，若仍不能(neng)消除嘯(xiao)(xiao)叫，則需要重新(xin)返回(hui)公司(si)做精密的調校(xiao)。（注意(yi)：不能(neng)長時間(jian)處于(yu)嘯(xiao)(xiao)叫狀態，以免(mian)會燒壞(huai)振鏡(jing)(jing)電機）

6、打標里不封口或封口過頭

改變打標軟件中“跳轉延時”，出光(guang)(guang)及關光(guang)(guang)等延時。若任都不行，則(ze)是(shi)(shi)振(zhen)鏡沒有(you)完全校正好，應(ying)(ying)該要返回公司，會返回供應(ying)(ying)商(shang)處，有(you)條件的激光(guang)(guang)維修(xiu)售后(hou)人員可以按(an)照振(zhen)鏡調試步驟做(zuo)一定的調節，但要注意(yi)有(you)幾個電位器是(shi)(shi)不是(shi)(shi)隨(sui)便(bian)亂動的。

7、打標時，打標頭下方，沒有激光輸出，但激光出光孔有激光

軟件打標速度大快，場鏡(jing)(jing)沒有安(an)裝(zhuang)，振(zhen)(zhen)鏡(jing)(jing)不(bu)動(dong)且擺的位置不(bu)正常(chang)，振(zhen)(zhen)鏡(jing)(jing)片(pian)(pian)脫落(luo)，振(zhen)(zhen)鏡(jing)(jing)片(pian)(pian)臟。前面幾個問題按上面的方法(fa)來處(chu)理，振(zhen)(zhen)鏡(jing)(jing)片(pian)(pian)脫落(luo)裂開，要(yao)返回公司重新換上新鏡(jing)(jing)片(pian)(pian)并調試好(hao)激(ji)光，振(zhen)(zhen)鏡(jing)(jing)片(pian)(pian)臟用品99%酒精和脫脂(zhi)棉擦(ca)(ca)試，如擦(ca)(ca)拭不(bu)了且是振(zhen)(zhen)鏡(jing)(jing)中(zhong)心部分(fen)，或(huo)者邊緣部分(fen)大1平(ping)方毫米則要(yao)更(geng)換振(zhen)(zhen)鏡(jing)(jing)片(pian)(pian)與振(zhen)(zhen)鏡(jing)(jing)片(pian)(pian)脫落(luo)一樣處(chu)理。

二、如何避免激光振鏡的二次污染

在一般功率輸出的(de)(de)(de)激光器(qi)中，所有(you)的(de)(de)(de)鏡片大都會(hui)由(you)于制造工(gong)藝的(de)(de)(de)原因或受外(wai)界污(wu)染等因素(su)導致鏡片對(dui)特(te)定的(de)(de)(de)激光波(bo)長吸收大，久而久之使(shi)鏡片壽命(ming)縮短，由(you)于鏡片的(de)(de)(de)損壞而造成影響使(shi)用甚至(zhi)停機的(de)(de)(de)情(qing)況時有(you)發生。

鏡(jing)片(pian)對激(ji)光波長(chang)吸收的增加會(hui)引起不(bu)均(jun)(jun)勻加熱導致鏡(jing)片(pian)的反射(she)(she)，折射(she)(she)率產生變化(hua)，激(ji)光波長(chang)從高(gao)(gao)吸收鏡(jing)片(pian)上(shang)透過或反射(she)(she)時激(ji)光功率的分(fen)布不(bu)均(jun)(jun)勻使鏡(jing)片(pian)中(zhong)心溫(wen)度高(gao)(gao)，邊緣(yuan)溫(wen)度低，產生這種變化(hua)在光學上(shang)稱透鏡(jing)效(xiao)應。

由(you)于污(wu)染(ran)導致鏡(jing)片(pian)高吸(xi)收引發熱(re)透鏡(jing)效(xiao)應(ying)會產生許多問題。透鏡(jing)基片(pian)的(de)(de)(de)(de)(de)不(bu)(bu)可逆熱(re)應(ying)力的(de)(de)(de)(de)(de)產生，光束(shu)傳播通過(guo)鏡(jing)片(pian)時所產生的(de)(de)(de)(de)(de)功率損(sun)(sun)耗，聚(ju)焦光點位(wei)置的(de)(de)(de)(de)(de)偏(pian)移動(dong)，鍍膜層(ceng)的(de)(de)(de)(de)(de)過(guo)早損(sun)(sun)壞等都能導致鏡(jing)片(pian)遭到(dao)破(po)壞。對于暴露在(zai)空(kong)氣中(zhong)的(de)(de)(de)(de)(de)鏡(jing)片(pian)，在(zai)做清(qing)(qing)理時，往往不(bu)(bu)遵循對鏡(jing)片(pian)清(qing)(qing)理的(de)(de)(de)(de)(de)要(yao)求和注意事項(xiang)，隨便取材(cai)，其結果將造(zao)(zao)成新(xin)的(de)(de)(de)(de)(de)污(wu)染(ran)甚(shen)至(zhi)劃傷(shang)鏡(jing)片(pian)，造(zao)(zao)成不(bu)(bu)可彌補的(de)(de)(de)(de)(de)損(sun)(sun)失。所以根(gen)據多年的(de)(de)(de)(de)(de)經(jing)驗總(zong)結認為：無論哪一類光學透鏡(jing)保(bao)持清(qing)(qing)潔(jie)是(shi)最(zui)重要(yao)的(de)(de)(de)(de)(de)，要(yao)有(you)良(liang)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(jian)少或清(qing)(qing)除有(you)關(guan)人(ren)為的(de)(de)(de)(de)(de)原(yuan)因(yin)所造(zao)(zao)成污(wu)染(ran)。

作(zuo)為(wei)(wei)一條常識，當(dang)用(yong)(yong)(yong)(yong)(yong)手去操作(zuo)光(guang)(guang)學系統時，無論清(qing)潔，拆(chai)(chai)卸，安裝都(dou)要帶(dai)上指(zhi)套或醫(yi)用(yong)(yong)(yong)(yong)(yong)手套，要始終保持遵循清(qing)洗(xi)鏡(jing)(jing)片(pian)的(de)(de)要求及注(zhu)意事項，在清(qing)潔過程中(zhong)，只能(neng)用(yong)(yong)(yong)(yong)(yong)規定的(de)(de)材料，如(ru)光(guang)(guang)學用(yong)(yong)(yong)(yong)(yong)的(de)(de)擦鏡(jing)(jing)紙，棉(mian)簽(qian)，試劑級(ji)乙醇。對任何鏡(jing)(jing)片(pian)的(de)(de)清(qing)潔，拆(chai)(chai)卸，安裝走捷(jie)徑都(dou)將(jiang)導致鏡(jing)(jing)片(pian)壽(shou)命縮(suo)短，甚至永(yong)久性(xing)地損壞。所以(yi)，要用(yong)(yong)(yong)(yong)(yong)普通(tong)的(de)(de)常識來防止(zhi)鏡(jing)(jing)片(pian)受其(qi)它原因的(de)(de)污(wu)染(ran)(ran)，如(ru)遇防潮(chao)濕、煙霧、防塵等(deng)等(deng)。在確定某一鏡(jing)(jing)片(pian)污(wu)染(ran)(ran)后，要用(yong)(yong)(yong)(yong)(yong)洗(xi)耳球(qiu)吹(chui)鏡(jing)(jing)片(pian)，直到其(qi)表面沒(mei)有微(wei)粒為(wei)(wei)佳，千萬不要用(yong)(yong)(yong)(yong)(yong)嘴去吹(chui)。因為(wei)(wei)吹(chui)出的(de)(de)空氣大都(dou)含油、水等(deng)將(jiang)會進一步污(wu)染(ran)(ran)鏡(jing)(jing)片(pian)。如(ru)果經過洗(xi)耳球(qiu)處(chu)理以(yi)后其(qi)表面仍有污(wu)染(ran)(ran)存在，就必(bi)須用(yong)(yong)(yong)(yong)(yong)專用(yong)(yong)(yong)(yong)(yong)的(de)(de)棉(mian)簽(qian)蘸實驗室級(ji)丙酮(tong)，乙醇來輕輕擦拭。這樣就可(ke)以(yi)清(qing)除大多數(shu)(shu)污(wu)染(ran)(ran)薄層。激光(guang)(guang)器中(zhong)的(de)(de)鏡(jing)(jing)片(pian)的(de)(de)污(wu)染(ran)(ran)會對激光(guang)(guang)輸出乃至數(shu)(shu)據采(cai)集(ji)系統造(zao)成嚴重(zhong)的(de)(de)采(cai)集(ji)錯誤(wu)，如(ru)果我們能(neng)夠使鏡(jing)(jing)片(pian)經常保持清(qing)潔，將(jiang)會延長整機(ji)的(de)(de)使用(yong)(yong)(yong)(yong)(yong)壽(shou)命。
