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(xian)檢查各(ge)(ge)連(lian)接(jie)線(xian)(xian)是(shi)(shi)(shi)否(fou)(fou)有(you)斷(duan)路或(huo)短路，連(lian)接(jie)是(shi)(shi)(shi)否(fou)(fou)正(zheng)(zheng)(zheng)確(que)，保險是(shi)(shi)(shi)否(fou)(fou)完好，確(que)認無誤后(hou)，打開(kai)(kai)(kai)(kai)電(dian)(dian)(dian)(dian)(dian)源，觀察振(zhen)鏡驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)板(ban)上(shang)的(de)(de)指示燈是(shi)(shi)(shi)否(fou)(fou)亮(liang)綠燈或(huo)黃燈。若(ruo)不(bu)(bu)亮(liang)或(huo)者(zhe)亮(liang)紅燈，則(ze)拔開(kai)(kai)(kai)(kai)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)板(ban)電(dian)(dian)(dian)(dian)(dian)源線(xian)(xian)，用萬用表測(ce)量其輸(shu)(shu)入端各(ge)(ge)端子的(de)(de)電(dian)(dian)(dian)(dian)(dian)壓是(shi)(shi)(shi)否(fou)(fou)為±24V。若(ruo)電(dian)(dian)(dian)(dian)(dian)壓正(zheng)(zheng)(zheng)常(chang)(chang)，側要(yao)再測(ce)試(shi)一(yi)(yi)下(xia)帶(dai)(dai)上(shang)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)板(ban)及機(ji)(ji)負載(zai)(zai)時(shi)，電(dian)(dian)(dian)(dian)(dian)壓是(shi)(shi)(shi)否(fou)(fou)正(zheng)(zheng)(zheng)常(chang)(chang)，如果(guo)都不(bu)(bu)正(zheng)(zheng)(zheng)常(chang)(chang)，則(ze)打開(kai)(kai)(kai)(kai)控制盒，不(bu)(bu)帶(dai)(dai)負載(zai)(zai)測(ce)試(shi)一(yi)(yi)下(xia)開(kai)(kai)(kai)(kai)關電(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)壓，如果(guo)電(dian)(dian)(dian)(dian)(dian)壓不(bu)(bu)正(zheng)(zheng)(zheng)常(chang)(chang)的(de)(de)話(hua)，剛開(kai)(kai)(kai)(kai)關電(dian)(dian)(dian)(dian)(dian)源損(sun)壞(huai)。電(dian)(dian)(dian)(dian)(dian)源輸(shu)(shu)入正(zheng)(zheng)(zheng)常(chang)(chang)后(hou)，連(lian)好所有(you)線(xian)(xian)后(hou)，上(shang)電(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)一(yi)(yi)般會發出(chu)二聲滴答音(yin)，若(ruo)沒(mei)有(you)響聲，再用手(shou)手(shou)輕推(tui)一(yi)(yi)下(xia)振(zhen)鏡片，稍有(you)點力度(du)，如果(guo)振(zhen)鏡片沒(mei)自鎖的(de)(de)話(hua)，則(ze)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)板(ban)壞(huai)，當然電(dian)(dian)(dian)(dian)(dian)壓輸(shu)(shu)出(chu)正(zheng)(zheng)(zheng)常(chang)(chang)的(de)(de)情況下(xia)，驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)板(ban)燈不(bu)(bu)亮(liang)或(huo)者(zhe)亮(liang)紅燈那就是(shi)(shi)(shi)振(zhen)鏡驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)板(ban)或(huo)者(zhe)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)有(you)問題，此(ci)時(shi)找(zhao)一(yi)(yi)塊確(que)認為完好的(de)(de)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)板(ban)，正(zheng)(zheng)(zheng)確(que)連(lian)接(jie)后(hou)，打開(kai)(kai)(kai)(kai)電(dian)(dian)(dian)(dian)(dian)源，振(zhen)鏡電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)還不(bu)(bu)自鎖，則(ze)是(shi)(shi)(shi)振(zhen)鏡電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)損(sun)壞(huai)，同理，找(zhao)一(yi)(yi)個確(que)認完好的(de)(de)振(zhen)鏡電(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)(dong)(dong)板(ban)上(shang)，打開(kai)(kai)(kai)(kai)電(dian)(dian)(dian)(dian)(dian)源，若(ruo)不(bu)(bu)上(shang)電(dian)(dian)(dian)(dian)(dian)，振(zhen)鏡驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)板(ban)損(sun)壞(huai)，如此(ci)反復的(de)(de)接(jie)拔線(xian)(xian)，請(qing)務必(bi)在斷(duan)電(dian)(dian)(dian)(dian)(dian)的(de)(de)情況下(xia)進行的(de)(de)。

2、振鏡電機有自鎖，但不夠力度

用一塊(kuai)確認完(wan)好(hao)的振(zhen)鏡(jing)(jing)驅動(dong)板(ban)和(he)(he)(he)一個完(wan)好(hao)的振(zhen)鏡(jing)(jing)電(dian)機(ji)，分別接在待測試的驅動(dong)板(ban)和(he)(he)(he)振(zhen)鏡(jing)(jing)頭上，正(zheng)常通電(dian)，用手輕輕轉動(dong)振(zhen)鏡(jing)(jing)軸，若變“硬”，則正(zheng)常；否則，可判定(ding)振(zhen)鏡(jing)(jing)驅動(dong)板(ban)和(he)(he)(he)振(zhen)鏡(jing)(jing)電(dian)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，則檢查振鏡信號連(lian)(lian)接(jie)線(xian)是(shi)否(fou)(fou)連(lian)(lian)接(jie)完好，確認連(lian)(lian)接(jie)無(wu)誤(wu)后(hou)，打標，若仍沒有擺動(dong)，則檢查信號線(xian)是(shi)否(fou)(fou)正負接(jie)反或者斷(duan)線(xian)，否(fou)(fou)則，則可(ke)斷(duan)定驅動(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)(zhen)鏡(jing)(jing)(jing)驅(qu)(qu)動(dong)板發熱(re)量稍高（出(chu)現干(gan)擾(rao)(rao)）檢查(cha)接(jie)地(di)(di)線是(shi)否(fou)(fou)(fou)正(zheng)確(que)接(jie)上（最好(hao)(hao)的(de)(de)(de)(de)(de)接(jie)地(di)(di)方法是(shi)：X振(zhen)(zhen)(zhen)鏡(jing)(jing)(jing)信(xin)號(hao)地(di)(di)，Y振(zhen)(zhen)(zhen)鏡(jing)(jing)(jing)信(xin)號(hao)地(di)(di)，屏蔽(bi)線，220V電(dian)源大地(di)(di)，及(ji)打(da)標(biao)機(ji)殼要連通）,若地(di)(di)線接(jie)上后仍(reng)有(you)(you)干(gan)擾(rao)(rao)，則(ze)(ze)(ze)首先檢查(cha)打(da)標(biao)卡卡是(shi)否(fou)(fou)(fou)正(zheng)常(chang)（檢查(cha)方法是(shi)用一塊確(que)認完好(hao)(hao)的(de)(de)(de)(de)(de)打(da)標(biao)卡換上，打(da)標(biao)看是(shi)否(fou)(fou)(fou)仍(reng)有(you)(you)干(gan)擾(rao)(rao)），若仍(reng)然有(you)(you)干(gan)擾(rao)(rao)，則(ze)(ze)(ze)進(jin)一步檢查(cha)振(zhen)(zhen)(zhen)鏡(jing)(jing)(jing)電(dian)機(ji)連接(jie)線是(shi)否(fou)(fou)(fou)完好(hao)(hao)，和其它線是(shi)否(fou)(fou)(fou)有(you)(you)纏(chan)繞，若一切正(zheng)常(chang)，則(ze)(ze)(ze)首先用一塊確(que)認完好(hao)(hao)的(de)(de)(de)(de)(de)振(zhen)(zhen)(zhen)鏡(jing)(jing)(jing)驅(qu)(qu)動(dong)板換上，若沒干(gan)擾(rao)(rao)，則(ze)(ze)(ze)可斷定振(zhen)(zhen)(zhen)鏡(jing)(jing)(jing)驅(qu)(qu)動(dong)板有(you)(you)問題；若有(you)(you)干(gan)擾(rao)(rao)，則(ze)(ze)(ze)振(zhen)(zhen)(zhen)鏡(jing)(jing)(jing)電(dian)機(ji)有(you)(you)問題。（當然公司(si)外出(chu)激光維(wei)修人員，請確(que)定好(hao)(hao)，如果客(ke)戶的(de)(de)(de)(de)(de)振(zhen)(zhen)(zhen)鏡(jing)(jing)(jing)是(shi)三(san)年以前的(de)(de)(de)(de)(de)產(chan)品，產(chan)品的(de)(de)(de)(de)(de)抵抗(kang)干(gan)擾(rao)(rao)能力肯定會差一點，振(zhen)(zhen)(zhen)鏡(jing)(jing)(jing)打(da)標(biao)頭周邊(bian)如有(you)(you)有(you)(you)手機(ji)信(xin)號(hao)，馬達，電(dian)機(ji)，磁場，又(you)或者(zhe)是(shi)Q開關的(de)(de)(de)(de)(de)射頻(pin)信(xin)號(hao)外露都有(you)(you)可能影響，新的(de)(de)(de)(de)(de)振(zhen)(zhen)(zhen)鏡(jing)(jing)(jing)都有(you)(you)可以發生這種現象）

5、產生嘯叫

先和第四步一(yi)樣，測試一(yi)下打標卡信號，布(bu)線，外部干擾等，如果(guo)還有(you)嘯(xiao)叫，則調(diao)試振(zhen)鏡驅(qu)動板(ban)的濾(lv)波板(ban)上(shang)電位器，若(ruo)仍不能消(xiao)除嘯(xiao)叫，則需要重(zhong)新返回公(gong)司做(zuo)精密的調(diao)校。（注意：不能長時間處(chu)于嘯(xiao)叫狀態(tai)，以免會燒壞振(zhen)鏡電機）

6、打標里不封口或封口過頭

改變(bian)打(da)標軟件中(zhong)“跳(tiao)轉延時(shi)(shi)”，出(chu)光(guang)及關光(guang)等延時(shi)(shi)。若(ruo)任(ren)都(dou)不行，則(ze)是(shi)振鏡沒(mei)有完全校正好(hao)，應該要返回(hui)公(gong)司，會返回(hui)供(gong)應商處，有條件的(de)激光(guang)維(wei)修售后人員可以(yi)按照振鏡調試步驟做一定的(de)調節，但要注(zhu)意(yi)有幾個電位器是(shi)不是(shi)隨(sui)便亂動(dong)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

軟件打標速度大快，場(chang)鏡(jing)沒有安裝(zhuang)，振(zhen)(zhen)鏡(jing)不動且擺的(de)位置不正常，振(zhen)(zhen)鏡(jing)片(pian)脫落(luo)(luo)，振(zhen)(zhen)鏡(jing)片(pian)臟(zang)。前(qian)面(mian)幾個(ge)問題按上(shang)面(mian)的(de)方法(fa)來(lai)處理，振(zhen)(zhen)鏡(jing)片(pian)脫落(luo)(luo)裂開，要返回公(gong)司重新(xin)換(huan)上(shang)新(xin)鏡(jing)片(pian)并調(diao)試(shi)好(hao)激(ji)光，振(zhen)(zhen)鏡(jing)片(pian)臟(zang)用(yong)品99%酒精和脫脂棉擦(ca)試(shi)，如擦(ca)拭(shi)不了且是振(zhen)(zhen)鏡(jing)中心(xin)部分(fen)，或者邊緣部分(fen)大1平(ping)方毫(hao)米(mi)則要更換(huan)振(zhen)(zhen)鏡(jing)片(pian)與振(zhen)(zhen)鏡(jing)片(pian)脫落(luo)(luo)一樣處理。

二、如何避免激光振鏡的二次污染

在一(yi)般功(gong)率輸(shu)出的激光(guang)器中，所有(you)的鏡(jing)片(pian)大都(dou)會由于制造工藝的原因或受外(wai)界污染等因素導致鏡(jing)片(pian)對(dui)特定的激光(guang)波(bo)長吸(xi)收大，久而(er)久之使鏡(jing)片(pian)壽命(ming)縮短，由于鏡(jing)片(pian)的損壞(huai)而(er)造成影(ying)響使用甚至(zhi)停機的情況時有(you)發生。

鏡(jing)(jing)片對激(ji)(ji)(ji)光(guang)波長吸收的增加(jia)會引起不(bu)均(jun)勻加(jia)熱導致(zhi)鏡(jing)(jing)片的反(fan)射，折射率產生(sheng)(sheng)變化，激(ji)(ji)(ji)光(guang)波長從高吸收鏡(jing)(jing)片上(shang)透(tou)過或(huo)反(fan)射時激(ji)(ji)(ji)光(guang)功率的分布(bu)不(bu)均(jun)勻使鏡(jing)(jing)片中心溫(wen)度(du)高，邊緣溫(wen)度(du)低，產生(sheng)(sheng)這種變化在光(guang)學上(shang)稱透(tou)鏡(jing)(jing)效應。

由于(yu)污(wu)染導(dao)致鏡(jing)(jing)片高(gao)吸收引發熱透鏡(jing)(jing)效應會產生許多(duo)問題。透鏡(jing)(jing)基片的(de)(de)(de)(de)(de)不可逆(ni)熱應力的(de)(de)(de)(de)(de)產生，光束(shu)傳播通過(guo)鏡(jing)(jing)片時(shi)所產生的(de)(de)(de)(de)(de)功率損耗，聚焦光點(dian)位置的(de)(de)(de)(de)(de)偏(pian)移動，鍍(du)膜層的(de)(de)(de)(de)(de)過(guo)早損壞(huai)等都能(neng)導(dao)致鏡(jing)(jing)片遭到破(po)壞(huai)。對(dui)于(yu)暴露在(zai)空氣中(zhong)的(de)(de)(de)(de)(de)鏡(jing)(jing)片，在(zai)做清理時(shi)，往(wang)往(wang)不遵循對(dui)鏡(jing)(jing)片清理的(de)(de)(de)(de)(de)要(yao)求和注意事項，隨便取材，其結(jie)果將造(zao)成(cheng)新的(de)(de)(de)(de)(de)污(wu)染甚至(zhi)劃傷鏡(jing)(jing)片，造(zao)成(cheng)不可彌(mi)補的(de)(de)(de)(de)(de)損失。所以根(gen)據多(duo)年的(de)(de)(de)(de)(de)經驗總結(jie)認(ren)為：無論哪一類光學(xue)透鏡(jing)(jing)保持清潔是最(zui)重要(yao)的(de)(de)(de)(de)(de)，要(yao)有良(liang)好(hao)的(de)(de)(de)(de)(de)清潔習慣去小心清洗鏡(jing)(jing)片，就能(neng)減少或(huo)清除有關人為的(de)(de)(de)(de)(de)原(yuan)因所造(zao)成(cheng)污(wu)染。

作為一條(tiao)常識(shi)(shi)，當用(yong)(yong)(yong)(yong)手去(qu)操作光學系統時(shi)，無論清(qing)(qing)潔(jie)，拆卸，安裝都(dou)要帶上指套(tao)(tao)或醫用(yong)(yong)(yong)(yong)手套(tao)(tao)，要始終保持遵(zun)循清(qing)(qing)洗(xi)鏡(jing)片(pian)(pian)(pian)的(de)(de)要求及(ji)注意事項，在清(qing)(qing)潔(jie)過程中，只能(neng)用(yong)(yong)(yong)(yong)規定的(de)(de)材料，如光學用(yong)(yong)(yong)(yong)的(de)(de)擦鏡(jing)紙，棉(mian)簽(qian)，試劑級乙(yi)醇(chun)。對(dui)任何鏡(jing)片(pian)(pian)(pian)的(de)(de)清(qing)(qing)潔(jie)，拆卸，安裝走捷徑(jing)都(dou)將(jiang)(jiang)導致鏡(jing)片(pian)(pian)(pian)壽命(ming)縮短，甚(shen)至永久性(xing)地損壞。所以(yi)，要用(yong)(yong)(yong)(yong)普通的(de)(de)常識(shi)(shi)來(lai)防(fang)止鏡(jing)片(pian)(pian)(pian)受其它原因的(de)(de)污(wu)(wu)染(ran)，如遇防(fang)潮濕、煙霧、防(fang)塵(chen)等(deng)(deng)等(deng)(deng)。在確(que)定某一鏡(jing)片(pian)(pian)(pian)污(wu)(wu)染(ran)后(hou)，要用(yong)(yong)(yong)(yong)洗(xi)耳球吹(chui)鏡(jing)片(pian)(pian)(pian)，直(zhi)到其表面沒有微粒(li)為佳，千萬(wan)不(bu)要用(yong)(yong)(yong)(yong)嘴去(qu)吹(chui)。因為吹(chui)出的(de)(de)空氣大都(dou)含油、水等(deng)(deng)將(jiang)(jiang)會進一步污(wu)(wu)染(ran)鏡(jing)片(pian)(pian)(pian)。如果經過洗(xi)耳球處理以(yi)后(hou)其表面仍(reng)有污(wu)(wu)染(ran)存(cun)在，就(jiu)必須用(yong)(yong)(yong)(yong)專用(yong)(yong)(yong)(yong)的(de)(de)棉(mian)簽(qian)蘸實驗室級丙酮，乙(yi)醇(chun)來(lai)輕(qing)輕(qing)擦拭。這樣就(jiu)可以(yi)清(qing)(qing)除大多(duo)數(shu)污(wu)(wu)染(ran)薄層。激光器(qi)中的(de)(de)鏡(jing)片(pian)(pian)(pian)的(de)(de)污(wu)(wu)染(ran)會對(dui)激光輸出乃至數(shu)據采(cai)(cai)集(ji)(ji)系統造成(cheng)嚴重的(de)(de)采(cai)(cai)集(ji)(ji)錯誤，如果我們(men)能(neng)夠使鏡(jing)片(pian)(pian)(pian)經常保持清(qing)(qing)潔(jie)，將(jiang)(jiang)會延長整機的(de)(de)使用(yong)(yong)(yong)(yong)壽命(ming)。
