Laser marking of moving parts without slowing down or stopping the movement saves time and increases productivity in the production process.

Call

Many mass-produced parts involve some type of continuous motion to maximize throughput. These include conveyor belts, spool winding processes, simple rotary movements or other types of moving production lines. To minimize the impact of laser marking on throughput throughout the production process, manufacturers need a laser marking method that adapts to moving parts without having to stop, slow down or pause the motion.

Solution

Coherent's on-the-fly laser marking technology solves this problem in a user-friendly way. The system's control card directly controls the galvo scanner so that the deflection of the laser beam continuously adjusts to the movement of the part. The user has several options to control this process via the system software. In the simplest case, the user enters the speed of the part movement. Alternatively, the laser marker can read signals from the motion sensor and adjust the marking process in real time to the measured speed. This method of operation is usually preferred because it copes with variations in production line motion and prevents errors in the marking process. The end result is higher yield and better marking consistency in terms of mark placement and quality. On-the-fly marking is available as an option on all Coherent PowerLine laser markers and is compatible with common metal and plastic marking methods, as well as the latest SmartProtect shallow marking and black marking techniques that are increasingly being used for marking stainless steel equipment.

Benefits

Laser marking on the fly is ideal for marking large volumes of small parts including electronic components, medical devices, consumer products and other mass produced equipment. Well suited for serial marking with indexed part numbers, etc. In addition, it provides accuracy and precision that also supports marking of functional scales and other auxiliary features.
