What control system should be selected for laser marking on assembly lines?

Laser marking is currently one of the most widely used marking and processing methods. The patterns or text produced by laser marking have a good texture and are indelible. They are often used in packaging, advertising, cables, consumer electronics and other products. Laser marking can be applied in both large-scale factories and small workshops, but different processing requirements require the use of different laser marking equipment.

Under assembly line conditions, the use of laser marking processing also has certain requirements for the control system. The control system is the control core of the laser marking machine. By outputting pulse signals, the control system can adjust the laser power, pulse width, processing pattern, processing method, etc. of the laser marking machine. The operator issues instructions through the control system to start processing, and then the control system can operate independently, achieving unmanned and intelligent processing.

Laser marking on assembly lines can be achieved using either a conventional laser control system or a visual laser control system.
If you want to use a regular laser control system without visual recognition function in an assembly line environment, you need fixtures with fixed processing objects on the assembly line, and the feeding interval of each batch should be consistent to ensure that the position of each processing object is fixed, otherwise errors may occur. This type of control system is generally used for relatively simple laser marking processing tasks and requires specialized supervision by personnel.

If using a visual laser marking control system, a visual laser control system with feature recognition function should be used. Feature recognition refers to the function of identifying the shape, color, marking and other characteristics of materials, correctly determining which objects need to be processed, and then starting marking processing.

The benefits of feature recognition are high intelligence, flexible processing methods, and fast processing speed. If equipped with a laser marking control system with feature recognition function, materials can be placed freely on the assembly line for operation. The system will automatically determine the objects that need to be processed and complete the processing, saving manpower, achieving higher automation, and faster processing efficiency.

Of course, visual laser marking control systems with feature recognition are relatively more expensive, and with hardware such as cameras and sensors, the overall deployment cost is much higher than that of ordinary laser marking systems. Maintenance in the later stage will also be more troublesome. Therefore, the specific choice of laser marking control system should still be based on one's own conditions and actual processing needs.
