1.清洗激光頭

1. Clean the laser head

碟機(jī)、光驅(qū)中的激光頭，因臟污易出現(xiàn)讀碟差、冷機(jī)不讀碟或徹底不讀碟等故障現(xiàn)象。利用超聲波清洗機(jī)清洗激光頭能徹底進(jìn)行清洗。步驟如下：

Due to dirt, the laser head in the disc drive and optical drive is easy to have faults such as poor disc reading, no disc reading in the refrigerator or no disc reading at all. The laser head can be cleaned thoroughly by ultrasonic cleaning machine. The steps are as follows:

（1）首先將激光頭保護(hù)焊點(diǎn)短接，然后拆下，用毛刷在自來水下將激光頭表面的灰塵、潤滑脂、紙標(biāo)貼等清除干凈（注意不要刷物境）。

(1) First, short circuit the laser head protection solder joint, then remove it, and use a brush to remove the dust, grease, paper labels, etc. on the surface of the laser head under tap water (pay attention not to brush the environment).

（2）在清洗槽中放入溫開水（40℃左右），滴入1～2滴餐具清洗劑溶解后，再將激光頭放入清洗液中浸泡1～5分鐘，然后開啟定時開關(guān)。使其自動進(jìn)行清洗。約5分鐘后清洗機(jī)自動停止。為達(dá)到徹底清洗的效果。按下定時開關(guān)再清洗一遍。

(2) Put warm boiled water (about 40 ℃) into the cleaning tank, drop 1 ~ 2 drops of tableware cleaning agent to dissolve, then soak the laser head in the cleaning solution for 1 ~ 5 minutes, and then turn on the timing switch. Make it clean automatically. After about 5 minutes, the cleaning machine will stop automatically. In order to achieve the effect of thorough cleaning. Press the timing switch to clean again.

（3）將清洗過兩次的激光頭浸入大盆清水中，然后取出，甩干內(nèi)部的水分（注意用拇指壓住循跡、聚焦線圈，以免變形損壞）。重復(fù)5、6次后，盡量把光腔內(nèi)的污水甩干凈。

(3) Immerse the laser head that has been cleaned twice in a large basin of clean water, then take it out and dry the internal water (pay attention to press the tracking and focusing coil with your thumb to avoid deformation and damage). After 5 or 6 repetitions, try to clean the sewage in the optical cavity.

（4）換上純凈的自來水（或純凈水、蒸餾水），放入激光頭，開啟開關(guān)進(jìn)行第二次清洗。并重復(fù)2、3次。

(4) Change into pure tap water (or pure water, distilled water), put in the laser head, turn on the switch for the second cleaning. And repeat 2 or 3 times.

（5）將清洗干凈的激光頭烘干，方法有多種：一是用干凈的餐巾紙包好后放在日光下自然晾曬；另一種方法是用電飯鍋充當(dāng)干燥鍋，先將電飯鍋置保于溫狀態(tài)，再將用干凈餐巾紙包裹多◆陶信龍層的激光頭放在鍋內(nèi)1～2小時，水分徹底蒸發(fā)干凈后即可。在北方冬季，也可將激光頭放在暖氣片上烘干。

(5) There are many ways to dry the cleaned laser head: first, wrap it with clean napkin and dry it naturally in the sun; Another method is to use the electric rice cooker as a drying pot. First, keep the electric rice cooker in a warm state, and then put the laser head wrapped with clean napkin with multi ◆ ceramic Xinlong layer in the pot for 1 ~ 2 hours. After the water is completely evaporated, it can be used. In northern winter, the laser head can also be dried on the radiator.

超聲波清洗機(jī)在家電中的的妙用

Application of ultrasonic cleaning machine in household appliances

2.清洗精密電路

2. Clean the precision circuit

板手機(jī)、碟機(jī)、平板彩電等采用精密雙層或多層線路板的電器，其印板與元件引腳易受潮、臟污發(fā)生漏電現(xiàn)象。因此。在檢修采用高精密多層線路板的家電時，對一些疑難故障，皆可先用超聲波清洗機(jī)對其精密主板進(jìn)行徹底清洗后再檢修。以避免維修陷入歧途。

For electrical appliances with precision double-layer or multi-layer circuit boards, such as mobile phones, disc players and flat-panel color TVs, their printing boards and component pins are prone to moisture, dirt and leakage. Therefore. When overhauling household appliances with high-precision multilayer circuit boards, for some difficult faults, the precision motherboard can be thoroughly cleaned with an ultrasonic cleaning machine before overhauling. In order to avoid the maintenance going astray.

3.清洗噴墨打印頭

3. Clean the inkjet print head

噴墨打印機(jī)的打印頭噴墨嘴堵塞。常用的浸泡法并不能使雜質(zhì)剝離。利用超聲波清洗可輕易進(jìn)入物件內(nèi)部清洗的特性，能徹底清洗噴墨打印頭的內(nèi)外。由于噴墨打印頭內(nèi)還附有精密電路板。清洗時應(yīng)采用純度較高的工業(yè)酒精。經(jīng)清洗完的打印頭應(yīng)烘干或自然晾干后才能上機(jī)試用。

The inkjet nozzle of the print head of the inkjet printer is blocked. The common immersion method can not peel off the impurities. Using the characteristic that ultrasonic cleaning can easily enter the interior of the object for cleaning, it can thoroughly clean the inside and outside of the inkjet print head. Because there is also a precision circuit board in the inkjet print head. Industrial alcohol with high purity shall be used for cleaning. The cleaned print head shall be dried or naturally dried before it can be put on the machine for trial use.

4.清洗其他各類器件

4. Clean other devices

我們在維修中不易拆解的檢測開關(guān)、精密鐘表機(jī)心、電腦CPU引腳、內(nèi)存條、錄像機(jī)磁鼓磁頭以及舊彩電和電腦的主板等器件。也可用超聲波清洗機(jī)進(jìn)行清洗，使其恢復(fù)青春。

We are not easy to disassemble the detection switch, precision clock movement, computer CPU pin, memory module, video recorder drum head, old color TV and computer motherboard. It can also be cleaned by ultrasonic cleaning machine to restore its youth.

5.清洗精密電機(jī)

5. Clean the precision motor

影碟機(jī)、錄像機(jī)等電器中廣泛采用的微型精密電機(jī)，長期運(yùn)轉(zhuǎn)后電機(jī)刷的觸點(diǎn)會磨損氧化，使接觸電阻增大甚至開路，導(dǎo)致電機(jī)轉(zhuǎn)動不暢或不轉(zhuǎn)等故障。清洗時，首先給待清洗電機(jī)噴入精密電機(jī)清洗液，然后快速轉(zhuǎn)動電機(jī)多次，使電刷上的氧化點(diǎn)剝落。若換向器凹槽內(nèi)仍有大量雜質(zhì)，可在電機(jī)兩端加上3～12V的直流電壓。放入盛有酒精的清洗機(jī)中，利用電機(jī)的高速運(yùn)轉(zhuǎn)使電刷上的氧化點(diǎn)進(jìn)一步被剝離，達(dá)到徹底根治的目的。

The micro precision motor widely used in DVD players, video recorders and other electrical appliances will wear and oxidize the contact of the motor brush after long-term operation, increase the contact resistance or even open circuit, resulting in poor rotation or non rotation of the motor. When cleaning, first spray precision motor cleaning fluid into the motor to be cleaned, and then quickly rotate the motor for many times to peel off the oxidation point on the brush. If there are still a lot of impurities in the commutator groove, a DC voltage of 3 ~ 12V can be added at both ends of the motor. Put it into the cleaning machine containing alcohol, and use the high-speed operation of the motor to further peel off the oxidation point on the brush, so as to achieve the purpose of radical cure.
