The Function and Working Principle of Laser Marking Card

What is a Laser Marking Card?

A laser marking card is a controller used to achieve precise marking with a laser marking machine. It mainly includes functional modules such as an interface circuit, arithmetic controller, driver circuit, and control software. Through the controller, it is possible to achieve high-speed, precise, and stable control of the laser marking machine, enabling it to complete various intricate marking tasks.

Working Principle of a Laser Marking Card

The working principle of a laser marking card is mainly divided into three parts: data processing, digital-to-analog conversion, and laser drive.

• Data Processing: In the laser marking card, the data processor is the core part. It parses the marking information input by the user and transmits the marking instructions to the subsequent circuit modules.

  
  

• Digital-to-Analog Conversion: The digital-to-analog converter converts digital instructions into analog signals to control the laser marking machine for marking. Simultaneously, the digital-to-analog converter can also transmit feedback data to the data processor for real-time adjustments.

  
  

• Laser Drive: The laser driver in the control card is responsible for controlling the operation mode of the laser. It converts signals into current to excite the laser for marking on the worktable.

Functions of a Laser Marking Card

• Controlling Laser Emission and Stopping: The laser marking card can control the emission and stopping of the laser to control the processing process.

  
  

• Parameter Adjustment: The effects of laser marking processing are also greatly related to the parameters. The laser marking card can adjust parameters such as laser power, pulse frequency, pulse width, etc., to meet different processing needs.

  
  

• Motion Control: The laser marking card can control the motion trajectory of the workpiece to achieve the marking of complex graphics or text.

  
  

• System Management: The laser marking card can manage the control system, including data storage, control program download, and other functions.

How to Purchase a Laser Marking Card

• Determine the Type of Control Card: Different types of control cards vary in functionality and working characteristics. Purchase according to actual needs.

  
  

• Determine the Performance of the Control Card: The performance of the control card directly affects the precision and operational efficiency of the marking machine. Purchase according to needs.

  
  

• Understand the Quality of the Control Card: Quality is one of the key factors in selecting a control card. Choose from reliable brands and manufacturers.

  
  

• Refer to User Reviews: User reviews are an important reference for purchasing a control card. Collect relevant information through online and physical stores.

In conclusion, the laser marking card is an important component of a laser marking machine. It is responsible for controlling the working mode of the laser and completing intricate marking tasks. Its functions include controlling laser emission and stopping, parameter adjustment, motion control, and system management. Proper selection and use of the control card are key to ensuring the stable operation of the laser marking machine and the marking effect.
