Application and Prospect of laser marking and marking information

With the rapid development of China manufacturing industry today, laser technology equipments are widely used in various fields such as based on automobile and parts, iron and steel, aerospace, hardware, kitchenware, sheet metal processing, packaging, electronic products, batteries, communications and other industries.According to the different form and power of laser, it can be divided into marking, cutting, welding, surface treatment, 3D printing and so on.Among them, laser marking is one of the most widely used and most closely integrated with information technology.

Mark with a kind of innate and natural attributes, it can generate data, including any of the characters, numbers, time and date, serial number, two-dimensional code, they all live data, traceability of the myriads of changes, strong.Marker information is very important in the manufacturing process.If the core of the cutting and welding is the processing technology, the core of the marking is data.With data, there is an urgent need for information management, and database, network, large-scale production and so on.In hardware, electronic products and other fields, and the word Logo is a must; in the automotive field, VIN generated code, the importance of self-evident; in the iron and steel, parts, packaging and other industries, the time and date, serial number, two-dimensional code, traceability is guaranteed.

In order to improve production efficiency and reduce management costs, more and more managers begin to realize the importance of network information management in the process of production.Laser marking systems are facing higher requirements, and they hope to be given more functions so that they can be seamlessly integrated into the whole production information management system.For example, if the contents are manually entered each time, it is very easy to make mistakes.Users want to click on the mouse several times to automatically obtain data, the records have to be saved to facilitate future production statistics, which requires marking software, with database literacy function.If users do not even bother to point the mouse, then you can increase the bar code scanning gun, sweep the two-dimensional code, the program will automatically tune out the relevant data and marking.

The following is a summary of several major applications from China’s laser equipment manufacturers:

1, support the database, to achieve remote or local data storage and access, database types include Access, SQL, Server, Oracle and so on.

2, through the RS232/485 and other ways to support the third party testing equipment, including electronic scales, bar code scanning guns, airtight detection, temperature monitoring, etc., to achieve the acquisition and processing of key data.

3, through Ethernet, support TCP/IP and third party terminals for network communication, to achieve production data interaction, remote command control.

4, through the I/O read and write control mode, to achieve in place testing, sensors, cylinder control, to complete all kinds of tooling clamping and movement.

5, through the connection with PLC, you can access the production line, online automatic operation, without manual intervention, improve production efficiency.

6, personalized information management system, including data write, modify, query, statistics, upload \ download, print documents and other functions.

7, combined with bar code printer, marking the paper at the same time to drive label paper printing, to achieve data traceability, improve production and logistics accuracy.

  1. Combining with the industrial camera, through the visual recognition of the shape of the workpiece, the intelligent positioning, marking and error correction of the workpiece are realized.

In short, laser marking has not only been satisfied with marking, we are more concerned about how the target data came in, and how to send out?. Just like a mobile phone, not just calling and texting, it is a mobile intelligent terminal, to the Internet, to play WeChat and Alipay and so on is interesting.In the future the trend of the development of networking technology, intelligent laser marking machine plays an increasingly important role, with the upgrading of manufacturing technology, laser marking the decades old equipment application, will be full of new vitality.

  3. Along with every little thing that seems to be building inside this particular area, a significant percentage of points of view happen to be fairly stimulating. Nonetheless, I beg your pardon, because I can not give credence to your whole theory, all be it stimulating none the less. It appears to everyone that your remarks are generally not completely validated and in fact you are yourself not thoroughly convinced of the assertion. In any event I did take pleasure in examining it.
