Application of imported laser marking machine in automobile industry
The laser marking machine (laser marking machine) uses a laser beam to make permanent marks on the surface of various substances. The effect of marking is to expose the deep material through the evaporation of the surface material, so as to engrave exquisite patterns, trademarks and characters. Laser marking machines are mainly divided into CO2 laser marking machines, semiconductor laser marking machines, and fiber laser marking machines. And YAG laser marking machine, the current laser marking machine is mainly used in some occasions requiring finer and higher precision. Used in electronic components, integrated circuits (IC), electrical appliances, mobile communications, hardware products, tool accessories, precision instruments, glasses and clocks, jewelry, auto parts, plastic buttons, building materials, PVC pipes.
The status of automobiles in people's lives is becoming more and more important, and it has gradually changed from a single means of transportation to a mobile living and office place. Diversified development. At the same time, with the increasing prosperity of the domestic economy, the national demand for automobiles has increased year by year, and the automobile industry has shown many new trends. For example, electric vehicles have begun to rise. Require.
Automotive manufacturing is a huge systematic project, which requires a series of process technologies to work together. In recent years, advanced technologies represented by laser processing, industrial robots, and digital control are constantly promoting the upgrading of the automobile manufacturing industry, and laser, as an advanced processing method, is destined to bring revolutionary breakthroughs to the development of the automobile manufacturing industry!
Laser welding is characterized by its high energy density, small deformation, narrow heat-affected zone, high welding speed, The advantages of easy automatic control and no follow-up processing have become one of the important means in industrial manufacturing. The automobile manufacturing industry is the industry that uses laser welding technology on a large scale in current industrial production. The flexibility of laser welding machines satisfies the processing of various materials for automobiles, reduces automobile production costs, improves production efficiency, and brings huge benefits to the automobile manufacturing industry. economic benefits.
Laser cutting is one of the most commonly used laser processing methods. The types of laser cutting are divided into laser vaporization cutting , laser melting cutting, laser oxygen cutting and laser scribing and controlled fracture four categories. The criteria for measuring the quality of the cutting process include cutting speed, cutting accuracy, stability and reliability. In the automotive industry, laser cutting is mainly used to quickly cut car body prototypes during the development of new models. Companies like BMW, Mercedes-Benz, Fiat, Volvo, Volkswagen, and others all have five-axis laser machines for this job.
With the introduction of national laws and regulations on automobile safety, the identity of automobiles and parts Uniqueness puts forward high requirements. The establishment of the identity of automobiles and parts is the basis for product quality traceability and recall. In order to strengthen the management of product three-guarantee claims, meet the requirements of the recall system for defective vehicle products, and achieve information collection and quality traceability of key parts and components.
Laser resistance trimming
The principle of laser resistance trimming is to use a very fine laser beam to hit the thick and thin film. On the resistor, the cutting of thick and thin film circuits is realized by vaporizing and evaporating the resistor body. The laser beam cuts the thick and thin film resistors according to the program predetermined by the computer, and changes the resistance value of the resistors by changing the geometric shapes of the thick and thin film resistors. As the laser cutting process progresses, the real-time measurement circuit monitors the changes in the resistance values u200bu200bof the thick and thin film resistors in real time, and the resistance values u200bu200bof the thick and thin film resistors are constantly approaching the target resistance value. That is, the laser resistance trimming process is realized.
Some automotive molds will wear out over a long period of time, thus affecting the use. If this mold is expensive, it would be a pity to scrap it. However, through the method of laser cladding incremental manufacturing, metallurgical powder is melted on the surface of the workpiece to restore its specifications, and then the workpiece can be reused after grinding. This process technology is called 'laser remanufacturing'. Laser remanufacturing can bring expensive molds back to life and turn waste into treasures with less capital, and the performance exceeds the past. This advanced 'laser remanufacturing' technology can undoubtedly save costs and reduce waste for enterprises. Create more value for the enterprise.
