Automated Laser Marking on Production Line — PLC-Controlled Solution for Steel Workpieces

Two weeks ago, we posted a video of one of our customers using their highly automated production facility. After receiving a new batch of orders from that customer last week, the video — which had only received a few hundred views on YouTube — was seen by the CEO of a different company with an automated production line. Within two days, we determined the most cost-effective solution based on the customer’s current production line and automation setup.

The customer chose a simpler sheet metal frame and control cabinet to accommodate operator preferences and ensure quick delivery. Since the steel products to be marked are on a production line, the customer opted to control them via a programmable logic controller (PLC). This setup enables the workpiece to stop at the front of the marking machine, send marking commands, and resume moving once the marking process is complete and the end signal is received.

The scanning galvanometer is initially in the rear position to prevent collision when the workpiece is moving. After receiving the marking signal, the Y-axis moves the guide rail into place for marking. Once marking is complete, the galvanometer returns to the initial position and stands by. The current workpiece does not require the Z-axis to raise or lower automatically. The customer needs to identify the manufacturer’s information and the serial number. In fact, the galvanometer can mark without moving. However, due to the occasional occurrence of workpieces of different sizes, the customer chose to add this module for more convenient line changes in the future.
