AutoTube Marker

Fully-automated robotic laser system for precision tube marking

Machine vision/validation, robotic part handling, and high-quality laser marking for fully automated production.

AutoTube Marker is a robotic tool for precision laser marking of high-value tubular parts, such as those used in medical devices. It provides a complete, automated solution allowing unattended operation. The system incorporates robotic part loading/unloading, machine vision/validation, a choice of laser sources (fiber laser, solid-state or ultrashort pulse), and 100% inspection, including part length, diameter, and mark contrast and content.

Precision laser marking for medical components


The Automatic Tube Marking System is an ideal solution for fully unattended, cost-effective production of laser marks on small tubes; the marks include UDI, Data Matrix codes, bar codes, and alphanumerics. The system’s ability to produce high-contrast marks on both metals and plastics, without any damage to the underlying material, makes it particularly useful for marking high-value components, such as those used in medical device manufacturing. AutoTube Marker delivers excellent performance and value by combining several features, including:

  • Fully automatic part processing, from bulk infeed handling, through part manipulation for marking and inspection, to output bin placement. It supports unattended operation for up to 30 minutes.
  • 100% integrated inline inspection of part dimensions and mark characteristics, with the ability to save every part image and automatically create a statistical database.
  • Simplified, efficient setup through the use of Coherent’s Visual LaserMarker (VLM) software, which enables mark layout on a PC and automatic transfer of the necessary marking data to the system.
  • A choice of laser source (fiber laser, solid-state or ultrashort pulse) to deliver optimum marking results on any material; when combined with the right laser source, the system can be used for black marking.
  • Industry 4.0 compatible for ease of integration.
  • Class I laser CDRH certification and CE certification for maximum operator safety.
