Introduction to 5-watt UV laser marking machine equipment
The power intensity of a 5-watt ultraviolet laser marking machine is much higher than that of a 3-watt ultraviolet laser marking machine, but some materials cannot be met by a 3-watt ultraviolet laser marking machine. Therefore, a 5-watt ultraviolet laser marking machine needs to be selected. This equipment is developed using a 355nm ultraviolet laser and uses third-order intracavity frequency doubling technology compared to infrared lasers, The focused spot of 355nm ultraviolet light is very small, and the marking effect is achieved by directly breaking the molecular chain of the material through short wavelength laser, which greatly reduces the mechanical deformation and thermal deformation of the material (belonging to cold light). Because it is mainly used for ultra-fine marking and engraving, it is particularly suitable for marking food, pharmaceutical packaging materials, micro hole drilling, high-speed division of glass materials, and complex graphic cutting of silicon wafers. The 5W ultraviolet laser marking machine is pumped by a high-power multi-mode laser diode to produce a laser beam that is doubled and then controlled by a computer to change the laser beam path through high-speed scanning galvanometer deflection to achieve laser marking.
Characteristics of 5-watt ultraviolet laser marking machine equipment
The 5-watt ultraviolet laser marking machine uses high-energy and high-density laser beams to carve and break molecular bonds on the surface of materials, causing them to detach from the material itself. The entire process does not generate heat, also known as "cold light". The focused spot is extremely small, resulting in excellent marking effects and extremely high precision. It is mainly used in the glass industry and for demanding fine marking.

Working principle of 5-watt ultraviolet laser marking machine
The working principle of the 5-watt ultraviolet laser marking machine is actually similar to that of other marking machines. Both use high-energy laser beams to focus on the surface of the object through a two-dimensional scanning mirror for engraving. However, due to the wavelength of the ultraviolet laser beam being 355nm, it will not damage the object due to thermal changes when engraving the surface of the objectIt can also be equipped with relevant auxiliary objects to achieve greater use
The 5-watt ultraviolet laser marking machine can be equipped with a two-dimensional cross mobile platform
The 5-watt ultraviolet laser marking machine can be equipped with a 360 degree synchronous rotating chuck
Application of 5-watt ultraviolet laser marking machine
Due to the extremely small spot size and good absorption of ultraviolet rays by objects, as well as the absence of thermal changes and environmental pollution, the 5-watt ultraviolet laser marking machine is widely used in various industries such as medical devices, pharmaceuticals, packaging, food, glass carving, cutting of flexible PCB circuit boards, chip drilling, cutting of flexible ceramics, and marking and carving of metal and plastic parts

Precautions for using a 5-watt ultraviolet laser marking machine
When using the 1.5-watt ultraviolet laser marking machine, it is important not to suddenly turn off the power during use, as this can cause computer data loss and even damage to the machine's hardware. It is recommended to install a UPS power stabilizer.
2. In harsh environments, regularly wipe the focusing lens with a dust-free cloth and use high concentration alcohol for wiping. Other lenses do not need to be wiped.
3. Do not frequently move the position. The internal components of the 5-watt ultraviolet laser marking machine are optical devices, and moving the position will cause internal parts to loosen, which will result in the machine not functioning properly
4. Non professionals are not allowed to open the chassis. Even if they need to open the chassis, they need to shut down the power and unplug the main power plug.
5. Regularly replace the cooling water inside the chiller.
6. It is strictly prohibited to look up from the bottom of the focusing lens during equipment operation to avoid permanent damage to the eyes.
7. When the equipment is working, try not to let your hands come into contact with the laser beam to avoid long-term contact and skin peeling.
