1.清洗激光头

1. Clean the laser head

碟机、光驱中的激光头，因脏污易出现读碟差、冷机不读碟或彻底不读碟等故障现象。利用超声波清洗机清洗激光头能彻底进行清洗。步骤如下：

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）将激光头保护焊点短接，然后拆下，用毛刷在自来水下将激光头表面的灰尘、润滑脂、纸标贴等干净（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）在清洗槽中放入温开水（40℃左右），滴入1～2滴餐具清洗剂溶解后，再将激光头放入清洗液中浸泡1～5分钟，然后开启定时开关。使其自动进行清洗。约5分钟后清洗机自动停止。为达到彻底清洗的效果。按下定时开关再清洗一遍。

(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）将清洗过两次的激光头浸入大盆清水中，然后取出，甩干内部的水分（注意用拇指压住循迹、聚焦线圈，以免变形损坏）。重复5、6次后，尽量把光腔内的污水甩干净。

(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）换上纯净的自来水（或纯净水、蒸馏水），放入激光头，开启开关进行第二次清洗。并重复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）将清洗干净的激光头烘干，方法有多种：一是用干净的餐巾纸包好后放在日光下自然晾晒；另一种方法是用电饭锅充当干燥锅，先将电饭锅置保于温状态，再将用干净餐巾纸包裹多◆陶信龙层的激光头放在锅内1～2小时，水分彻底蒸发干净后即可。在北方冬季，也可将激光头放在暖气片上烘干。

(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.

超声波清洗机在家电中的的妙用

Application of ultrasonic cleaning machine in household appliances

2.清洗精密电路

2. Clean the precision circuit

板手机、碟机、平板彩电等采用精密双层或多层线路板的电器，其印板与元件引脚易受潮、脏污发生漏电现象。因此。在检修采用高精密多层线路板的家电时，对一些疑难故障，皆可先用超声波清洗机对其精密主板进行彻底清洗后再检修。以避免维修陷入歧途。

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.清洗喷墨打印头

3. Clean the inkjet print head

喷墨打印机的打印头喷墨嘴堵塞。常用的浸泡法并不能使杂质剥离。利用超声波清洗可轻易进入物件内部清洗的特性，能彻底清洗喷墨打印头的内外。由于喷墨打印头内还附有精密电路板。清洗时应采用纯度较高的工业酒精。经清洗完的打印头应烘干或自然晾干后才能上机试用。

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.清洗其他各类器件

4. Clean other devices

我们在维修中不易拆解的检测开关、精密钟表机心、电脑CPU引脚、内存条、录像机磁鼓磁头以及旧彩电和电脑的主板等器件。也可用超声波清洗机进行清洗，使其恢复青春。

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.清洗精密电机

5. Clean the precision motor

影碟机、录像机等电器中广泛采用的微型精密电机，长期运转后电机刷的触点会磨损氧化，使接触电阻增大甚开路，导致电机转动不畅或不转等故障。清洗时，给待清洗电机喷入精密电机清洗液，然后快速转动电机多次，使电刷上的氧化点剥落。若换向器凹槽内仍有大量杂质，可在电机两端加上3～12V的直流电压。放入盛有酒精的清洗机中，利用电机的高速运转使电刷上的氧化点进一步被剥离，达到彻底根治的目的。

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.
