The Coherent ExactMark 210 TL - with 6-axis robotic parts handling - fully automates multi-sided laser marking of small parts trays.

Many medical devices, disposables and other high-volume components require permanent marking on more than one side. However, the unit value of these parts is often low, which means they cannot be individually marked by hand. This bulk marking task is even more challenging where parts are not simple shapes with straight sides.

The latest Coherent ExactMark 210 TL is designed to provide an economical and practical solution to this common problem by integrating the robotic arm capability within the work cell - ideal for applications in medical devices and disposables, electronic components, machine tools and other industries.

The six-axis robotic handling option delivers key benefits, including lower labor costs and shorter batch processing times.

  • Multi-sided marking - robotically assisted marking on multi-sided objects
  • Non-contact operation - parts handling
  • PartVision - automatic alignment and verification after marking
  • Long MTBA - up to 30 part trays in one batch
  • Simple and intuitive operation - user-friendly Laser FrameWork software

Figure 1. The ExactMark 210 TL enables multi-sided marking of up to 30 trays without operator intervention.

The combination of tray insertion - up to 30 trays per cycle - and multi-axis robotic handling shortens the cycle time and supports long Mean Time Between Assist (MTBA), minimizing operator intervention and labor costs. This is particularly advantageous for multi-sided marking applications of asymmetric parts such as medical devices. All marking can be performed using a machine vision feature called PartVision for automated and accurate mark placement. PartVision can also check and verify the quality of the marking.

The operation of the ExactMark 210 TL is integrated under the intuitive Coherent Laser FrameWork software suite, which simplifies the creation and execution of any marking task through a simple drag-and-drop functionality. The user places marking, inspection and automation steps on the job timeline using simple drag-and-drop operations. The software also supports different levels of user access, allowing production operators to operate equipment without having to set job parameters.

The ExactMark 210 TL is available with a range of infrared lasers from 6 to 95 watts, enabling cost-effective marking of both plastics and metals. It is also offered with the Varia laser, which allows the laser pulse characteristics to be precisely configured to suit different marking tasks. In addition, this new marker can accommodate parts up to 40 mm high with support for JEDEC trays or pallets.
