The advertising industry has always been the best stage for laser technology to show its unique characteristics. Here, laser technology can express different needs in a variety of ways, such as light, shadow, vocal, and action. The magical effect reflects the characteristics of laser technology. To be vivid. The application of signboards and signs is one of the main areas where laser processing technology is widely used. The promotion and application of laser engraving and cutting machines has injected new life into the advertising industry and pushed the development of signboards and signs to another application. peak.
First, the working principle of laser engraving and cutting machine
Laser has the characteristics of high coherence, directionality and high intensity. It is easy to obtain a high luminous flux density, focus a strong beam on the medium, and use the process of laser-substance interaction to change the properties of the material. This is laser processing . Popularly speaking, it is excited by a specific medium substance to generate a high-energy beam and control the beam. When the beam hits a point on the surface of the object-the point material quickly melts or vaporizes due to high temperature, so as to achieve what we need. Predetermined material form, that is, to change the material form by controlling the energy, speed, direction, and trajectory of the laser. Meeting our needs is laser processing . Laser engraving and laser cutting are two different working methods. Laser engraving usually consists of carbon dioxide laser, special laser engraving software, automatic control system and precision machinery. It belongs to low-cost high-tech laser products. Lasers, automatic control systems, and precision mechanical parts are the keys to measuring machines. Laser cutting is the use of a focused high-energy laser beam to melt or vaporize the workpiece, and use an auxiliary gas to blow out the molten or oxide to form a cut. Laser cutting is one of the most mature and widely used laser processing technologies in laser processing .
Features of laser engraving and cutting machine
Compared with mechanical processing, laser processing has the following advantages. Laser processing has the significant advantages of wide processing objects, small deformation, high accuracy, energy saving, low pollution, non-contact long-distance processing, and automatic processing. Narrow slits, fine engraving, and blind grooves that can be cut freely; can be easily applied to ultra-thin, fragile, brittle, soft, hard materials and synthetic materials; fast cutting speed; no tool wear; easy CNC and computer control : Convenient for assembly line operations. With the development of optical, electromechanical, material, computer and control technology, it has gradually become a new processing technology. The laser engraving and cutting machine combines the functions of laser engraving and laser cutting, and places higher requirements on the laser and the control system. It combines all the advantages of engraving and cutting. The machine is multi-purpose and has higher cost performance. It is currently widely used in advertising technology, Mold models, printing plates, furs, leather goods, electronic instruments and other industries.
Application of CO2 laser
The industrial development of each country is different, and the industrial field of laser processing systems is also different. The United States and Japan are all countries with widespread processing applications, and South Korea is one of the countries with developed microelectronics industries. The United States is a leader in the application of laser technology, while Germany is at the forefront of the world in laser material processing equipment. The level of laser technology is mainly reflected in the level of laser technology and applications based on it. The discharge of C02 RF laser is uniform and stable, and the laser beam quality is better than that of laser, which is the main development direction of gas laser. With the development of technology, the shortcomings of large beam length-to-width ratio, unsuitable for finishing, and expensive costs are gradually solved, and CO2 RF lasers have unlimited prospects.
China's optoelectronic technology is an area with a small gap from the international level. It started almost at the same time as the world. Especially after the reform and opening up, the optoelectronic information industry featuring lasers has rapidly risen as an industrial force. The concept of "China's Optics Valley" proposed by Wuhan, Guangdong, Shanghai, and Changchun has all achieved important achievements and great progress.
The domestic CO2 laser has a certain gap with the international level and has a short life, but the price is only 10% of similar foreign products. The product performance can basically meet the needs of the domestic market, and has been widely used in some industries. The market potential is still considerable.
