The working principle of laser coding machine is mainly to quickly print specific marks onto the surface of the product through laser technology. Laser coding machines use high-energy laser beams to directly act on the surface of the object being sprayed, achieving coding effects through high-temperature evaporation or oxidation. The specific process includes the following steps: firstly, the laser generates a high-energy laser beam; Then, the laser beam is focused into small light spots through a lens and instantly irradiated onto the surface of the sprayed object; Subsequently, the irradiated material is subjected to heat, rapidly heating up and undergoing chemical changes such as oxidation, evaporation, etc; Finally, form clear and durable coding marks.
The core components of a laser coding machine include a laser, marking control card, beam expander, galvanometer, and field lens. The laser provides the laser light source, the marking control card is responsible for receiving instructions and accurately controlling the action of the marking equipment, the beam expander reduces the divergence angle of the laser beam and increases its diameter, the galvanometer quickly and accurately changes the scanning direction of the laser beam, and the field lens determines the marking range and focuses the light on a plane. These components work together to ensure the accuracy and efficiency of the laser coding machine.
Laser coding machines have a wide range of applications, including industries such as food, clothing, spare parts, electronic products, and mechanical components. It can not only print information such as text, numbers, and graphics, but also print QR codes and barcodes on product surfaces or packaging, providing clear traceability and readability markings. In addition, laser coding machines do not require consumables, are easy to maintain, and can create permanent marks, enhancing the market competitiveness of products.
