Dynamic marking with laser|Case Study: Development of a Laser Marking System

In this article, we look at the need for real-time transmission of dynamic data in the context of industrial automation, and through an example of a laser marking system, we explore how millisecond-level interaction between production line data and laser equipment can be achieved.The system integrates dynamic data marking technology with an industrial internet of things architecture, supporting real-time laser engraving of variable information such as QR codes and serial numbers. It has already achieved zero error marking in the automotive parts and electronics components industries, effectively increasing the flexibility and responsiveness of production lines.

In the process of upgrading to smart manufacturing, laser marking systems for dynamic, real-time data transfers are becoming the core solution for marking products on production lines.A manufacturer of automotive components faced problems of low efficiency in coordinating production data and laser equipment, and delays in updating dynamic content.The team used the MQTT protocol to build a real-time communication framework to directly transmit order parameters from the ERP system to the laser controller. This successfully reduced the data response time from 5 seconds to less than 200 milliseconds.

The hardware layer employs industrial-grade fiber lasers and high-precision galvanometers, while the software has a visual parameter configuration interface that allows operators to use drag-and-drop to create dynamic variable templates.For example, in the scene where the engine block is being stamped, the system can instantly capture 12 pieces of information such as the VIN number and production batch, and automatically generate a QR code with a check digit.By deploying edge computing nodes, the system is able to maintain its ability to continuously label data stored locally even when the network fluctuates.

The project overcame three technical challenges: First, it solved the problem of dropped frames caused by high-frequency data streams by optimizing the buffer management strategy. Second, it developed an adaptive power adjustment algorithm to ensure consistent marking depth on different materials. Third, it created a dual verification mechanism that compares the visual inspection system with the database in real time, keeping the error rate below one in a million.The system has been running smoothly for 18 months at three manufacturing companies, and has processed as many as 120,000 dynamic labels in a single day. It has helped clients reduce their inventory costs by 60 % compared to traditional preprinted labels.
