System Using Profinet Communication for Improving a Laser Engraver

Abstract

This article presents a system created by the authors using Profinet communication for improving a laser engraver machine used in industrial processes for creating parts. Especially in the automotive industry, but also in many other manufacturing processes, a laser engraver is used to ensure the recognition and traceability of the parts within the production process. The system incorporates an operator panel for management, an easier way to define and apply engraving models, and a user permission system for better operability. The productivity is increased by changing the landmark involves two simple operations, changing the nest and the recipe. By introducing the Electronic Key system is eliminated unauthorized changes. Due to the RFID system and working with recipes is making impossible the incorrectly loading of the inscription program. The system allows modification of the laser program for each piece, and in the case of complex parts, data from the 2D code of the components received from another supplier to be found in the 2D code on the assembled part. Due to the multitude of messages and signals, an easy diagnosis of the machine is displayed on the operator panel, showing the status of the sensors on the machine, the status of the monitoring signals, and the error messages. A correct treatment of non-compliant parts by evaluating the signals and implementing the scrap box is making available.
