How It Works


The operation of the machine is straightforward and effective. Visitors were invited to access a dedicated web page where they could enter personal information like their name, phone number, email, and company, and input the message they wanted engraved on a pen. Upon data confirmation, a message was sent, and the machine was activated to select a pen, perform the customized engraving, and finally, deliver the pen to the visitor.

Technical Details and Benefits


Selmatron has incorporated various technologies into this special machine, providing the following technical and operational advantages:


Multi-Platform Interactivity: The use of a multi-platform web page enabled visitors to interact with the machine via their devices, making the user experience more accessible and convenient.

Security and Hosting: To ensure secure access and data protection, the web page was hosted on a VPS (Virtual Private Server), showcasing the technology's accessibility for small businesses without advanced IT resources.


MQTT Protocol and Encryption: The messages exchanged between the web page and the machine utilized MQTT protocol, adding an extra layer of security and preventing direct access to the machine's address.


Edge Learning: Using Cognex's Smart Camera Edge Learning technology, it was possible to accurately detect the pen's position for robotic retrieval, yielding results comparable to Deep Learning but with fewer samples and iterations.


Synchronization and Flexibility: The SVS-Vistek vision system's synchronization with Beckhoff's Motion XTS System allowed for precise measurements on the pens without requiring the item to stop for analysis.


Multi-Tasking Robot: The integrated robot performed multiple tasks, some of which would typically require pneumatic systems (e.g., opening/closing doors).

Applicability in Various Industrial Contexts


 This special machine from Selmatron offers versatile applications that bring advantages in various industrial settings, including:


  • Decentralized Automation: The decentralized web platform allows for the supervision and interaction with the machines through existing computer platforms. This enables access within private networks or remotely.
  • Modularization and Integration: The use of VPS allows for modularizing the solution and integrating different private or cloud servers, making it adaptable to the specific needs of each client.
  • Flexible Protocol: The freely usable MQTT protocol offers flexibility in implementation, either through public or private brokers. This allows for adaptation to each client's security and encryption needs.
  • Efficiency and Quality: The technologies used, such as Edge Learning and the synchronization of the vision system with XTS, allow for precise measurements and pattern detection without interrupting production, increasing both the efficiency and quality of the processes. The XTS system also allows for asynchronous execution of processes and construction flexibility, enabling the organization of single and multiple stations in a hybrid manner.
  • Efficient Data Exchange: The interface communicates with the PLC through the ADS protocol, enabling its implementation in various languages at a high acquisition rate, as well as data loggers with superior resolution and a more fluid interface. ADS is a communication protocol developed by Beckhoff to allow efficient real-time data exchange between different components, which is essential for applications where synchronization and quick response are crucial.
  • Robot Integration: Currently, integrated robots in machines perform multiple tasks, including some that typically require pneumatic systems (such as opening and closing doors). Pneumatic systems are generally more energy-expensive.
