At present, there are more and more friends using mobile phone laser marking machines in the market. Because many manufacturers do not know about laser marking machines, there are often some minor problems when using them. In order to avoid such things from happening again, the editor of Shenzhen Simeda Electronics Co., Ltd. will tell you about the precautions for the operation of mobile phone laser marking machines. 1. Cooling water must be pure and non-viscous, and should be replaced frequently. It is best to clean the tank regularly with distilled water. It is strictly forbidden to start the laser power supply under the condition of no water or abnormal water circulation. This may damage the machine. 2. The laser and optical lenses of the mobile phone laser marking machine are fragile, so handle them with care to avoid vibration. The output of the laser power supply cannot be suspended in the air to prevent ignition and breakdown with other electrical appliances. When the laser is working, it cannot touch or collide with the movable beam of the scanning table. to avoid collision damage. 3. If the laser attenuation is found to be unusable, the krypton lamp needs to be replaced. YAG krypton lamps can generally be used for three months. If you find it is aging or cracked, have it replaced by a professional. Try not to disassemble and replace by yourself. 4. When the slide bar of the scanning table runs unevenly, apply some lubricating oil to the shaft. 5. Environmental protection requirements, clean and dust-free, keep the surface of the machine clean, humidity: 30 ~ 80% (no condensation), temperature: 5 ~ 40 degrees, preferably with ventilation equipment, no strong vibration, no heating elements around.
