Technology drives development, innovation leads the future

Sky laser  launches a new technology for automatic focusing

Leading the development trend of laser cleaning industry

1. Overview of autofocus technology

Automatic focusing technology is a technology developed by Xiangming Laser, specifically designed for cleaning workpieces with uneven surfaces or those that are difficult to place horizontally. Through high-precision laser ranging sensors, the surface height of the workpiece is measured in real time, and the linkage controller adjusts the height of the laser cleaning head in real time to ensure that the focal length is maintained in real time during workpiece cleaning.

2. Autofocus principle

Using a laser ranging sensor to detect the height of the cleaned surface, the measurement data is transmitted to the equipment controller PLC. The PLC stores and calculates the step value of the cleaned surface height, which is converted into a vertical height compensation value. At the same time, the servo drive system is controlled to operate the servo motor, achieve vertical height compensation, and complete the automatic adjustment of the focal length.

3. Advantages of autofocus technology

Wide application range, high automatic focusing accuracy, unrestricted by material surface conditions, simple structure, no damage to material surface, intelligent integration, good stability, one click operation

4. Application and prospect of autofocus technology

Automatic focusing technology has been widely used in laser cutting and other laser processing fields due to its advantages such as high accuracy and independence from material surface conditions. Laser cleaning, as a dark horse industry in the field of laser processing in recent years, has greatly improved its technological development, but there is still room for improvement in controlling cleaning accuracy.

To enhance the precision control of laser cleaning, Wuhan Xiangming Laser has innovatively combined automatic focusing technology with laser cleaning, achieving real-time focus maintenance during the workpiece cleaning process. The application of autofocus technology will greatly expand the application of laser cleaning in high-precision and cutting-edge technology fields such as automotive manufacturing, rail transit, aerospace, etc.
