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

先檢查各連接(jie)(jie)(jie)線是否(fou)(fou)有(you)(you)斷(duan)(duan)路或(huo)短路，連接(jie)(jie)(jie)是否(fou)(fou)正(zheng)(zheng)確(que)，保(bao)險是否(fou)(fou)完好(hao)(hao)，確(que)認無(wu)誤后(hou)，打(da)(da)開(kai)電(dian)(dian)(dian)(dian)源，觀(guan)察振(zhen)(zhen)鏡(jing)(jing)驅(qu)(qu)動(dong)(dong)(dong)(dong)板(ban)(ban)(ban)上的指示燈(deng)(deng)(deng)是否(fou)(fou)亮(liang)(liang)綠燈(deng)(deng)(deng)或(huo)黃(huang)燈(deng)(deng)(deng)。若不(bu)亮(liang)(liang)或(huo)者(zhe)亮(liang)(liang)紅燈(deng)(deng)(deng)，則拔(ba)開(kai)驅(qu)(qu)動(dong)(dong)(dong)(dong)板(ban)(ban)(ban)電(dian)(dian)(dian)(dian)源線，用(yong)萬用(yong)表測(ce)量其(qi)輸入端(duan)各端(duan)子的電(dian)(dian)(dian)(dian)壓是否(fou)(fou)為±24V。若電(dian)(dian)(dian)(dian)壓正(zheng)(zheng)常(chang)(chang)，側(ce)要再測(ce)試一(yi)(yi)下(xia)(xia)(xia)(xia)帶上驅(qu)(qu)動(dong)(dong)(dong)(dong)板(ban)(ban)(ban)及(ji)機(ji)負載時(shi)，電(dian)(dian)(dian)(dian)壓是否(fou)(fou)正(zheng)(zheng)常(chang)(chang)，如(ru)(ru)果(guo)都不(bu)正(zheng)(zheng)常(chang)(chang)，則打(da)(da)開(kai)控制盒，不(bu)帶負載測(ce)試一(yi)(yi)下(xia)(xia)(xia)(xia)開(kai)關電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓，如(ru)(ru)果(guo)電(dian)(dian)(dian)(dian)壓不(bu)正(zheng)(zheng)常(chang)(chang)的話，剛(gang)開(kai)關電(dian)(dian)(dian)(dian)源損壞(huai)。電(dian)(dian)(dian)(dian)源輸入正(zheng)(zheng)常(chang)(chang)后(hou)，連好(hao)(hao)所有(you)(you)線后(hou)，上電(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)機(ji)一(yi)(yi)般會發出二聲滴答音，若沒(mei)有(you)(you)響聲，再用(yong)手手輕推一(yi)(yi)下(xia)(xia)(xia)(xia)振(zhen)(zhen)鏡(jing)(jing)片，稍有(you)(you)點力度(du)，如(ru)(ru)果(guo)振(zhen)(zhen)鏡(jing)(jing)片沒(mei)自鎖的話，則驅(qu)(qu)動(dong)(dong)(dong)(dong)板(ban)(ban)(ban)壞(huai)，當然電(dian)(dian)(dian)(dian)壓輸出正(zheng)(zheng)常(chang)(chang)的情(qing)況下(xia)(xia)(xia)(xia)，驅(qu)(qu)動(dong)(dong)(dong)(dong)板(ban)(ban)(ban)燈(deng)(deng)(deng)不(bu)亮(liang)(liang)或(huo)者(zhe)亮(liang)(liang)紅燈(deng)(deng)(deng)那就是振(zhen)(zhen)鏡(jing)(jing)驅(qu)(qu)動(dong)(dong)(dong)(dong)板(ban)(ban)(ban)或(huo)者(zhe)電(dian)(dian)(dian)(dian)機(ji)有(you)(you)問題，此時(shi)找(zhao)一(yi)(yi)塊確(que)認為完好(hao)(hao)的驅(qu)(qu)動(dong)(dong)(dong)(dong)板(ban)(ban)(ban)，正(zheng)(zheng)確(que)連接(jie)(jie)(jie)后(hou)，打(da)(da)開(kai)電(dian)(dian)(dian)(dian)源，振(zhen)(zhen)鏡(jing)(jing)電(dian)(dian)(dian)(dian)機(ji)還不(bu)自鎖，則是振(zhen)(zhen)鏡(jing)(jing)電(dian)(dian)(dian)(dian)機(ji)損壞(huai)，同理(li)，找(zhao)一(yi)(yi)個確(que)認完好(hao)(hao)的振(zhen)(zhen)鏡(jing)(jing)電(dian)(dian)(dian)(dian)機(ji)，接(jie)(jie)(jie)到不(bu)上電(dian)(dian)(dian)(dian)的驅(qu)(qu)動(dong)(dong)(dong)(dong)板(ban)(ban)(ban)上，打(da)(da)開(kai)電(dian)(dian)(dian)(dian)源，若不(bu)上電(dian)(dian)(dian)(dian)，振(zhen)(zhen)鏡(jing)(jing)驅(qu)(qu)動(dong)(dong)(dong)(dong)板(ban)(ban)(ban)損壞(huai)，如(ru)(ru)此反復的接(jie)(jie)(jie)拔(ba)線，請務必在斷(duan)(duan)電(dian)(dian)(dian)(dian)的情(qing)況下(xia)(xia)(xia)(xia)進行的。

2、振鏡電機有自鎖，但不夠力度

用(yong)一塊確認(ren)完(wan)好(hao)的(de)振鏡驅動板和一個完(wan)好(hao)的(de)振鏡電機(ji)，分別接在(zai)待測(ce)試的(de)驅動板和振鏡頭(tou)上，正(zheng)常通電，用(yong)手輕輕轉(zhuan)動振鏡軸，若變“硬”，則正(zheng)常；否則，可判定振鏡驅動板和振鏡電機(ji)損(sun)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(lian)接線(xian)是(shi)否(fou)連(lian)接完(wan)好，確認連(lian)接無誤后，打標，若仍(reng)沒有擺動，則(ze)檢查信(xin)號線(xian)是(shi)否(fou)正負(fu)接反或者(zhe)斷線(xian)，否(fou)則(ze)，則(ze)可斷定(ding)驅動板損壞。

4、打標出現波浪線，打標頭機有輕微的叫聲

振(zhen)(zhen)(zhen)鏡(jing)驅(qu)(qu)動(dong)板(ban)發熱量稍高(gao)（出(chu)現干(gan)擾）檢(jian)查接(jie)地(di)線是(shi)否(fou)(fou)正確接(jie)上(shang)（最好(hao)(hao)的(de)接(jie)地(di)方法是(shi)：X振(zhen)(zhen)(zhen)鏡(jing)信(xin)(xin)號地(di)，Y振(zhen)(zhen)(zhen)鏡(jing)信(xin)(xin)號地(di)，屏蔽線，220V電(dian)源大(da)地(di)，及打標機(ji)殼(ke)要連(lian)通）,若(ruo)(ruo)地(di)線接(jie)上(shang)后仍(reng)有(you)(you)干(gan)擾，則(ze)首先檢(jian)查打標卡(ka)卡(ka)是(shi)否(fou)(fou)正常(chang)（檢(jian)查方法是(shi)用一塊確認完好(hao)(hao)的(de)打標卡(ka)換(huan)(huan)上(shang)，打標看是(shi)否(fou)(fou)仍(reng)有(you)(you)干(gan)擾），若(ruo)(ruo)仍(reng)然有(you)(you)干(gan)擾，則(ze)進一步檢(jian)查振(zhen)(zhen)(zhen)鏡(jing)電(dian)機(ji)連(lian)接(jie)線是(shi)否(fou)(fou)完好(hao)(hao)，和其它線是(shi)否(fou)(fou)有(you)(you)纏繞，若(ruo)(ruo)一切正常(chang)，則(ze)首先用一塊確認完好(hao)(hao)的(de)振(zhen)(zhen)(zhen)鏡(jing)驅(qu)(qu)動(dong)板(ban)換(huan)(huan)上(shang)，若(ruo)(ruo)沒干(gan)擾，則(ze)可(ke)斷定(ding)振(zhen)(zhen)(zhen)鏡(jing)驅(qu)(qu)動(dong)板(ban)有(you)(you)問(wen)題(ti)；若(ruo)(ruo)有(you)(you)干(gan)擾，則(ze)振(zhen)(zhen)(zhen)鏡(jing)電(dian)機(ji)有(you)(you)問(wen)題(ti)。（當然公司外(wai)出(chu)激光維修人(ren)員，請(qing)確定(ding)好(hao)(hao)，如果客(ke)戶的(de)振(zhen)(zhen)(zhen)鏡(jing)是(shi)三年以前的(de)產品，產品的(de)抵抗干(gan)擾能力肯定(ding)會差一點，振(zhen)(zhen)(zhen)鏡(jing)打標頭(tou)周邊如有(you)(you)有(you)(you)手機(ji)信(xin)(xin)號，馬達，電(dian)機(ji)，磁場(chang)，又或者是(shi)Q開關的(de)射頻信(xin)(xin)號外(wai)露(lu)都(dou)有(you)(you)可(ke)能影響(xiang)，新的(de)振(zhen)(zhen)(zhen)鏡(jing)都(dou)有(you)(you)可(ke)以發生(sheng)這(zhe)種現象）

5、產生嘯叫

先(xian)和第四步一(yi)樣，測(ce)試(shi)一(yi)下打標卡信號，布線(xian)，外部干擾等，如果還有(you)嘯(xiao)(xiao)叫，則調試(shi)振鏡(jing)驅(qu)動板的濾波板上(shang)電(dian)(dian)位器，若仍不能(neng)消除嘯(xiao)(xiao)叫，則需要重新返回公司做(zuo)精密(mi)的調校(xiao)。（注意：不能(neng)長時(shi)間處于嘯(xiao)(xiao)叫狀態，以免會燒壞振鏡(jing)電(dian)(dian)機）

6、打標里不封口或封口過頭

改變打標軟件(jian)中(zhong)“跳轉延時”，出光及關光等延時。若任都(dou)不行(xing)，則(ze)是振鏡沒有(you)完全校正好，應該(gai)要返回(hui)公司，會返回(hui)供應商處(chu)，有(you)條件(jian)的激(ji)光維(wei)修(xiu)售后人員可以按(an)照振鏡調(diao)試步驟做一定的調(diao)節，但要注意有(you)幾個電位器是不是隨便亂(luan)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(ruan)件(jian)打標速度大快，場鏡(jing)(jing)(jing)沒有(you)安裝，振(zhen)鏡(jing)(jing)(jing)不動且擺的位置不正常，振(zhen)鏡(jing)(jing)(jing)片(pian)(pian)(pian)脫落(luo)，振(zhen)鏡(jing)(jing)(jing)片(pian)(pian)(pian)臟(zang)。前面(mian)幾個問題(ti)按上面(mian)的方法來處理，振(zhen)鏡(jing)(jing)(jing)片(pian)(pian)(pian)脫落(luo)裂(lie)開，要(yao)返回公司重新(xin)換上新(xin)鏡(jing)(jing)(jing)片(pian)(pian)(pian)并調試(shi)好激光(guang)，振(zhen)鏡(jing)(jing)(jing)片(pian)(pian)(pian)臟(zang)用(yong)品99%酒(jiu)精和脫脂棉擦試(shi)，如擦拭(shi)不了(le)且是振(zhen)鏡(jing)(jing)(jing)中心(xin)部分(fen)，或者(zhe)邊緣(yuan)部分(fen)大1平方毫米則要(yao)更換振(zhen)鏡(jing)(jing)(jing)片(pian)(pian)(pian)與振(zhen)鏡(jing)(jing)(jing)片(pian)(pian)(pian)脫落(luo)一樣處理。

二、如何避免激光振鏡的二次污染

在一般功(gong)率輸出的激光器中，所(suo)有的鏡片(pian)(pian)大都(dou)會由于制造工藝的原因(yin)或受外界污(wu)染(ran)等因(yin)素導(dao)致鏡片(pian)(pian)對特定(ding)的激光波長吸收大，久而久之使鏡片(pian)(pian)壽命(ming)縮短，由于鏡片(pian)(pian)的損壞而造成影響使用甚至停(ting)機的情況(kuang)時有發生。

鏡片對激(ji)光(guang)波(bo)長吸(xi)收(shou)的增加會(hui)引(yin)起不均(jun)勻(yun)加熱導(dao)致鏡片的反射，折射率產生(sheng)變(bian)化，激(ji)光(guang)波(bo)長從高(gao)吸(xi)收(shou)鏡片上(shang)透過或反射時激(ji)光(guang)功率的分(fen)布不均(jun)勻(yun)使(shi)鏡片中心溫度高(gao)，邊緣(yuan)溫度低，產生(sheng)這(zhe)種(zhong)變(bian)化在光(guang)學上(shang)稱透鏡效(xiao)應。

由(you)于污(wu)(wu)染(ran)導(dao)致(zhi)鏡(jing)(jing)片(pian)(pian)高吸收(shou)引發熱透鏡(jing)(jing)效應(ying)會產(chan)(chan)生許多問題。透鏡(jing)(jing)基片(pian)(pian)的(de)(de)(de)(de)不可(ke)逆熱應(ying)力的(de)(de)(de)(de)產(chan)(chan)生，光束傳播通過鏡(jing)(jing)片(pian)(pian)時所產(chan)(chan)生的(de)(de)(de)(de)功率(lv)損(sun)耗，聚焦光點位置(zhi)的(de)(de)(de)(de)偏(pian)移動(dong)，鍍(du)膜層的(de)(de)(de)(de)過早損(sun)壞等都(dou)能(neng)導(dao)致(zhi)鏡(jing)(jing)片(pian)(pian)遭到破壞。對于暴露在空氣中的(de)(de)(de)(de)鏡(jing)(jing)片(pian)(pian)，在做清(qing)理(li)時，往往不遵循(xun)對鏡(jing)(jing)片(pian)(pian)清(qing)理(li)的(de)(de)(de)(de)要求(qiu)和注(zhu)意事項，隨便取材，其(qi)結(jie)果將造(zao)成(cheng)(cheng)新的(de)(de)(de)(de)污(wu)(wu)染(ran)甚至劃傷鏡(jing)(jing)片(pian)(pian)，造(zao)成(cheng)(cheng)不可(ke)彌補的(de)(de)(de)(de)損(sun)失。所以(yi)根據多年的(de)(de)(de)(de)經驗總結(jie)認為：無(wu)論哪一類光學透鏡(jing)(jing)保持(chi)清(qing)潔是最重要的(de)(de)(de)(de)，要有良好的(de)(de)(de)(de)清(qing)潔習(xi)慣去小心清(qing)洗(xi)鏡(jing)(jing)片(pian)(pian)，就能(neng)減(jian)少或清(qing)除(chu)有關人為的(de)(de)(de)(de)原(yuan)因所造(zao)成(cheng)(cheng)污(wu)(wu)染(ran)。

作為一條(tiao)常識，當用(yong)(yong)手去操(cao)作光(guang)學系(xi)統時，無論清(qing)(qing)(qing)潔，拆(chai)卸，安裝都(dou)(dou)要(yao)(yao)(yao)帶(dai)上指(zhi)套(tao)(tao)或醫用(yong)(yong)手套(tao)(tao)，要(yao)(yao)(yao)始終保持遵循清(qing)(qing)(qing)洗鏡(jing)片的(de)(de)(de)(de)(de)要(yao)(yao)(yao)求(qiu)及(ji)注意事(shi)項，在(zai)清(qing)(qing)(qing)潔過程中，只能用(yong)(yong)規定的(de)(de)(de)(de)(de)材料，如光(guang)學用(yong)(yong)的(de)(de)(de)(de)(de)擦鏡(jing)紙(zhi)，棉(mian)(mian)簽(qian)，試劑(ji)級乙醇。對任何鏡(jing)片的(de)(de)(de)(de)(de)清(qing)(qing)(qing)潔，拆(chai)卸，安裝走捷徑都(dou)(dou)將(jiang)(jiang)導(dao)致(zhi)鏡(jing)片壽命縮短，甚至(zhi)永(yong)久性地損(sun)壞。所以，要(yao)(yao)(yao)用(yong)(yong)普通的(de)(de)(de)(de)(de)常識來防(fang)止鏡(jing)片受其(qi)它(ta)原(yuan)因的(de)(de)(de)(de)(de)污(wu)染(ran)(ran)，如遇(yu)防(fang)潮濕、煙霧、防(fang)塵等(deng)等(deng)。在(zai)確定某一鏡(jing)片污(wu)染(ran)(ran)后(hou)，要(yao)(yao)(yao)用(yong)(yong)洗耳球吹鏡(jing)片，直到其(qi)表(biao)面(mian)沒有微粒為佳，千萬不要(yao)(yao)(yao)用(yong)(yong)嘴(zui)去吹。因為吹出(chu)的(de)(de)(de)(de)(de)空氣大都(dou)(dou)含油、水(shui)等(deng)將(jiang)(jiang)會進一步污(wu)染(ran)(ran)鏡(jing)片。如果經過洗耳球處(chu)理以后(hou)其(qi)表(biao)面(mian)仍有污(wu)染(ran)(ran)存在(zai)，就必須(xu)用(yong)(yong)專用(yong)(yong)的(de)(de)(de)(de)(de)棉(mian)(mian)簽(qian)蘸實驗室(shi)級丙酮，乙醇來輕輕擦拭。這樣就可(ke)以清(qing)(qing)(qing)除大多數(shu)污(wu)染(ran)(ran)薄層。激光(guang)器(qi)中的(de)(de)(de)(de)(de)鏡(jing)片的(de)(de)(de)(de)(de)污(wu)染(ran)(ran)會對激光(guang)輸(shu)出(chu)乃至(zhi)數(shu)據采(cai)集系(xi)統造成(cheng)嚴重(zhong)的(de)(de)(de)(de)(de)采(cai)集錯誤(wu)，如果我們(men)能夠使鏡(jing)片經常保持清(qing)(qing)(qing)潔，將(jiang)(jiang)會延長整機的(de)(de)(de)(de)(de)使用(yong)(yong)壽命。
