The ultraviolet laser marking machine belongs to the series of laser marking machines, but it is developed using a 355nm ultraviolet laser. Compared with infrared lasers, this machine uses third-order intracavity frequency doubling technology. The 355 ultraviolet light focuses on very small light spots, which can greatly reduce the mechanical deformation of the material and have little processing heat impact.
Because it is mainly used for ultra fine marking and carving, it is particularly suitable for applications such as marking and micro hole marking of food and pharmaceutical packaging materials, high-speed division of glass materials, and complex graphic cutting of silicon wafers.
When using a UV laser marking machine, there are some precautions to follow, including:
1. Correctly adjust the focal length
During the operation process, it is necessary to adjust the focal length of the marking head according to actual needs. If the focal length is too close or too far, it will affect the clarity and effectiveness of the marking. For specific methods, please refer to the equipment's user manual and follow the adjustment method provided by the manufacturer for operation.
2. Reasonable selection of marking parameters
The selection of marking parameters directly affects the quality of the marking effect. It is necessary to reasonably select parameters such as laser power, scanning speed, and pulse frequency based on different material properties and marking requirements. If unsure of which parameters to choose, small sample experiments can be conducted to find the most suitable parameter combination.
3. Keep equipment clean
The beam generator and lenses of the UV laser marking machine need to be regularly cleaned and maintained to maintain the equipment in good working condition. The cooling system of the equipment should be regularly checked for normal operation to avoid a decrease in marking quality caused by overheating. At the same time, attention should be paid to avoiding impurities such as dust entering the equipment during operation to prevent damage to the equipment.
4. Preparation and handling before and after processing
Before using a UV laser marking machine for processing, necessary treatment should be carried out on the processed materials to ensure that the surface is clean and dust-free. After processing, the marking surface should be cleaned in a timely manner to maintain cleanliness. For materials with special requirements, protective measures should also be taken to avoid damage.
5. Safe use
The ultraviolet laser marking machine belongs to laser equipment, and safety precautions should be taken when using it to avoid direct exposure to ultraviolet light. Corresponding protective glasses should be worn.
6. Maintenance and upkeep
Regularly check the normal operation of all components of the laser marking machine, and promptly repair and maintain any abnormalities found to ensure the long-term stable use of the equipment.
7. Reasonable operation
Follow the instructions for using the laser marking machine to avoid prohibited or unsafe operations and protect the safety of equipment and personnel.
