With the deepening of industrial automation, the manufacturing industry has a growing demand for automated laser marking. As a high-precision and high-efficiency marking equipment, laser marking machine plays an important role in the manufacturing industry. However, traditional laser marking machine operation relies on manual labor, which is not only inefficient, but also difficult to meet the demand for flexibility and automation in modern manufacturing. In this paper, we will discuss how to automate the operation of laser marking machines through communication with MES (Manufacturing Execution System).

1. laser marking machine automation needs

Laser marking machines are widely used in the manufacturing industry, including but not limited to electronics, automotive, medical devices and other fields. With the advancement of industrial automation, the demand for automated laser marking is also increasing. Automated laser marking not only improves production efficiency, but also reduces human error and ensures consistent product quality.

2. Limitations of traditional laser marking machines

Ordinary laser marking machines usually require manual operation of the graphical interface or buttons to perform the marking task, this mode of operation has a low degree of automation, and can not meet the rapidly changing production needs. In addition, this method can not achieve large-scale customized production, limiting the diversity and personalization of products.

3. Primary automated marking program

In order to improve the degree of automation, some primary automated marking solutions use simple I/O signals to control the laser marking machine. In this scenario, the laser marking machine will output a pulse signal after marking is completed to notify the system that its work has been completed. Although this method can realize automated marking when the template file has been set, its limitation is that the marking content is fixed and cannot be changed according to the production demand.

4. Communication with MES system to realize real automation

In order to realize the real laser automation marking, the laser marking machine must be able to communicate with the MES system, which not only can control the laser marking machine to start marking, but also can dynamically modify the text content, position of the mark to adapt to the changing production needs. The realization of this function requires the following key points:

a) Hardware level data communication support

The laser marker must support data communication at the hardware level, which usually means it needs to have interfaces such as serial or network ports. These interfaces allow the laser marker to receive commands and data from the MES system.

b) Communication protocol support at the software level

At the software level, the laser marking software needs to support specific communication protocols that are compatible with the MES system. A communication protocol is a pre-agreed data transfer format for the laser marking machine to interact with the MES system. This "language" ensures the accurate transmission and interpretation of data and is the key to automated marking.

5. Realization of automated marking steps

In order to realize the communication between the laser marking machine and the MES system, the following are some basic steps:

1. interface configuration: ensure that the communication interface of the laser marking machine is compatible with that of the MES system.

2. Protocol Docking: Develop or configure the laser marking software to support the communication protocols used by the MES system.

3. Data exchange: Establish a data exchange mechanism to ensure that the MES system can send the correct commands and data to the laser marking machine.

4. Testing and validation: Conduct adequate testing to ensure that the entire system can operate stably in various production scenarios.

5. User Training: Train operators to familiarize them with the new automated marking process.

6. Conclusion

Through the communication integration with the MES system, the laser marking machine can realize the real automation operation, which not only improves the production efficiency, but also enhances the flexibility of production. With the continuous progress of technology, the future laser marking machine will be more intelligent and better serve the automation needs of the manufacturing industry.
