Laser marking machine (laser coding machine) is to use laser beam to mark the surface of various materials. The function of marking is to use the transpiration of the surface raw materials to exude the deep raw materials, so as to engrave exquisite patterns, trademark logos and words. Laser marking machine can be mainly divided into: fiber laser marking machine, co2 laser marking machine and ultraviolet laser marking machine, etc. At that time, the laser marking machine was mainly used for some occasions with high marking accuracy. Used in electronic components, integrated circuits (IC), electrical appliances, mobile communications, hardware products, tool accessories, equipment, glasses and clocks, jewelry, auto parts, plastic buttons, building materials, PVC pipes, etc.

There are many types of laser marking machines, and the laser marking machines used in each manufacturing industry will be different.

Principle of co2 laser marking machine

The co2 laser marking machine (co2 laser marking machine) is a laser galvanometer laser marking machine with carbon dioxide gas as the working medium. The co2 laser marking machine uses carbon dioxide gas as the medium, and the auxiliary gas such as carbon dioxide is charged into the discharge tube, and high voltage is applied to the electrode to generate a glow discharge in the discharge tube, so that the gas emits a laser with a wavelength of 10.64um, and the laser is amplified by energy. , scanned by galvanometer, focused by F-Theta mirror, under the control of computer and laser marking control card, images, characters, numbers and lines can be marked on product workpieces according to customer standards.

Advantages of co2 laser marking machine: It adopts carbon dioxide laser, which is a general-purpose model. It adopts the rear focusing method, which is small in size and high in integration. This equipment is suitable for laser marking of most non-metallic raw materials, such as paper packaging, plastic products, label stickers, leather products fabrics, glass ceramics, resin plastics, bamboo and wood products, PCB boards, etc.

Today, laser Marking machines are more and more widely used in various industries. As a new type of mechanical equipment, it mainly includes laser cutting machine, laser cleaning machine, laser marking machine, laser welding machine, etc. A subversive change of laser equipment can complete standardized and intelligent production and processing, which is energy-saving, ecological, environmentally friendly, and has a high degree of intelligence. It can also complete remote control and actual operation, greatly reducing the labor force and improving the office environment. Moreover, the production speed and product grade have been greatly improved, which has promoted the development and progress of new technologies.

The co2 laser marking machine uses a laser beam to engrave sexual marks on the surface of various items, while the co2 laser marking machine is an intelligent automation technology that integrates lasers, computers, and mechanical equipment, and does not require high environmental requirements. Harsh, the advantages and disadvantages of the mechanical equipment environment will directly affect the performance indicators, yield and service life of the mechanical equipment.

Therefore, in the actual operation of the laser marking machine, the environment must be treated strictly, and what kind of environment has the advantages of the co2 laser marking machine:

1. The cooling method of individual laser marking machines is usually frost-free water cooling, such as semiconductor laser marking machines. Therefore, in order to ensure the quality of the cooling circulating water, mineral water or distilled water can be used directly, and the cooling circulating water should be replaced regularly.
2. The environment of the co2 laser marking machine should be indoors, the temperature is between 20°C and 30°C, and the ambient humidity is 30%-80%, so that the laser equipment can be produced and processed indoors. the same state.
3. The power supply and wire of the co2 laser marking machine must meet the needs of the machine and equipment. The fluctuation of the power supply cannot be higher than 10%, and the ground wire must be grounded.
