The design of laser marking machine is a kind of sheet metal design. Laser printer uses laser beam to carve exquisite patterns, trademarks or characters on the surface of various materials and mark them permanently. The effect of laser marking is to expose the deep substance through the evaporation of the surface substance; or the mark formed by the chemical and physical changes of the surface substance through light energy; or the light energy burns off part of the substance, showing patterns and characters, and can engrave a variety of Non-metallic materials. Laser marking machine is mainly divided into CO2 laser marking machine, semiconductor laser marking machine, fiber laser marking machine and YAG laser marking machine. Laser marking machine is mainly used in some occasions requiring finer and higher precision. Compared with inkjet marking machines, laser marking machines have a wide range of applications and can be used in clothing accessories, pharmaceutical packaging, wine packaging, architectural ceramics, beverage packaging, fabric cutting, rubber products, shell nameplates, craft gifts, electronic components, leather and other industries. There is no force on the surface of the workpiece, no mechanical deformation, and no corrosion on the surface of the material. The design of laser marking machine has a special control system, LCD touch screen control mode, simple man-machine interface and humanized design, and the operation of the equipment is easier and easier to understand. The sealed structure can reduce the radiation of the machine. The transparent window design not only allows the staff to intuitively understand the operating conditions of the equipment, facilitates the adjustment of operation, but also improves the safety and reliability of the machine. The pulley design under the machine body reduces the difficulty of equipment transportation and movement, and improves the flexibility of equipment use. The design of laser marking machine conforms to ergonomics, and designers carry out a series of innovations from appearance design, structural design and mold opening. Simple and comfortable human-computer interaction, the operation is very simple and convenient, and the performance is safe and stable; the shape is neat and intuitive, simple and modern, the body is integrated and the overall structure, the surface shell is treated by a special process, smooth and clean, not only anti-impact, anti-oxidation, Strong and durable, but also conducive to cleaning and maintenance. It has the characteristics of small size, low power consumption, long life, high efficiency, maintenance-free, high-quality laser beam, fine spot, and no need for consumables. It is accepted and loved by more and more users.
