Uv Laser Engraving Machine

UV laser engraving machine

 

 

The UV flying marking machine is an advanced device that uses UV lasers and a flying marking galvanometer system to perform high-speed, high-quality permanent marking on objects while they are in continuous motion (flight).

 

The Ultraviolet Flying Laser engraving Machine represents the pinnacle of modern laser marking technology. Designed for high-speed production lines, it delivers exceptionally precise, permanent, and high-contrast marks on a wide array of materials without any physical contact. Its core innovation lies in utilizing a cold-light UV laser source, making it ideal for applications where heat damage and low contrast are critical concerns. Flying laser engraving machines are available in 3W, 5W, 10W, and 15W power options, tailored to customer needs.

 

 

 

 

Applications of the Flying 3W UV Laser Engraving Machine:

The Flying UV Laser Marking Machine, with its unique low-power laser beam, is particularly well-suited for processes operating on high-speed assembly lines. It is used in the high-end market for ultra-fine processing, marking the surfaces of cosmetics, pharmaceuticals, video, and other polymer packaging bottles. The markings are precise, durable, and superior to inkjet coding, with zero pollution. It is also used for marking QR codes on LCD glass, drilling holes in glassware, marking metal coatings, plastic buttons, electronic components, gifts, communications equipment, and building materials.

 

 

Technical Features:

· Integration: Easily integrates with PLCs, sensors, and automated production lines

 

How UV laser engraving machine works:

 

 

This system operates on the principle of"on-the-fly" marking. As products move continuously on the conveyor belt, the machine's advanced galvanometer scanner head and precise synchronization software control the laser beam. The UV laser  interacts with the target material through a photochemical process called "cold ablation." This process efficiently breaks down the molecular bonds of the material without generating significant heat, thereby vaporizing it minimally to create a smooth, clear mark.

 

Synchronous Tracking: The device integrates high-precision sensors (such as photoelectric sensors and encoders). When the sensors detect a product entering the marking area, the marking system is immediately triggered.

 

Dynamic Positioning: The system uses an encoder to obtain real-time information about the conveyor or production line speed and synchronizes this speed signal to the marking head's galvanometer system. The galvanometers (high-speed rotating mirrors) dynamically adjust the laser beam's focus position based on the product's real-time position, ensuring that the laser spot "catches up" and "follows" the moving product during engraving.

 

 

Efficient Production: This means that products can be marked at full production speed without stopping, significantly improving production efficiency and making it ideal for assembly line operations.

 

 

Application: Date and batch code printing on plastic packaging for food and pharmaceuticals

 

Industries: Fast-moving consumer goods (FMCG) industries such as food, pharmaceuticals, and health supplements.

 

Traditional methods: Conventional ink-jet (CIJ) coding suffers from issues such as easy erasure, environmental pollution, and high consumable costs. Traditional laser (fiber) coding can cause plastic packaging to melt and deform due to thermal effects, producing a burnt odor.

Flying UV laser engrving machine advantages 

 

1. Superior Marking Quality: The short wavelength of the UV laser allows for a much smaller focal point, enabling the creation of extremely fine details, small fonts, and complex QR codes or barcodes with impeccable readability.

 

2. Cold Processing: The photochemical ablation process generates negligible heat, eliminating thermal stress, burning, melting, or micro-cracks. This makes it perfect for sensitive materials like plastic films, electronic components, and medical devices.

 

3. High Contrast Marks: It produces stark, high-contrast marks (often white or light) on surfaces that are traditionally difficult to mark, such as dark plastics, glass, and metals, without any pre-treatment.
