My last post before absconding for vacation included an overview of Fabtech 2021—the first trade show I’ve visited in two years. Aside from the additive manufacturing area, the next most active area for me was collaborative robots. Much of the activity concerned welding. People at the Universal Robot booth told me that smaller companies have trouble hiring welders. The smaller cost of these robots plus speed from delivery to production make them an attractive alternative.
Universal Robots used FABTECH 2021 as the launchpad for new cobot applications including heavy-duty water-cooled welding, hardfacing, plasma cutting, and flexible machine loading.
UR cobot-powered systems were mainstream at FABTECH with numerous OEMs and UR+ partners actively selling MIG, TIG and plasma welding and cutting solutions, making it one of the fastest growing market for UR cobots.
“For 40 years, robotic arc welding evolved incrementally”, says Joe Campbell, Senior Manager of Applications Development and Strategic Marketing at Universal Robots. “Collaborative arc welding is the first disruptive technology to hit the robotic arc welding market since the introduction of DC servo powered robots,” he adds, attributing the rapid market traction to several key drivers including significant shortage of welders, increase in high mix/low volume production, and the fact that cobot welders are easy to deploy, quickly producing parts with improved quality and consistency.
Heavy-duty welds are now possible to perform with cobots as Vectis Automation becomes the first UR partner in North America to develop a water-cooled cobot-based welding system in a new version of its Cobot Welding Tool. The solution is now not only compatible with Miller welding equipment but can be integrated with Lincoln and Fronius welding equipment too.
Vectis Automation also pioneers the use of a UR cobot for hardfacing, the metalworking process where harder or tougher material is applied to a base metal. The company debuted new UR cobot powered plasma cutting as well, featuring Vectis’ Cobot Cutting Tool with Hypertherm PowerMax able to perform complex cuts on 3D shapes and large structures for a fraction of the cost of a tube laser.
The UR booth also hosts new solutions for automated machine tending, featuring the new VersaBuilt CNC Mill Application Kit for manufacturers seeking a plug-and-play approach to CNC milling automation. Versabuilt’s UR+ Application Kit comes with all components pre-assembled and designed to successfully get the CNC mill and the UR10e cobot working together, automating the loading and unloading of parts into the mill. The VersaBuilt Kit requires no programming experience with easy-to-use automation software that allows the machinist to simply enter part dimensions and CNC milling program numbers to get the application up and running.
Universal Robots’ ActiNav combines intelligent vision and real-time autonomous motion control with Universal Robots’ e-Series cobots. ActiNav combines real-time autonomous motion control, UR cobots, vision and sensor systems in one seamless Application Kit that solves the bin picking challenge in machine tending applications. At FABTECH, ActiNav picked metal parts randomly jumbled in bins and correctly insert them into a machine. Powering ActiNav is the new enhanced version of UR’s best-selling UR10e cobot now featuring 25% more payload capacity with the ability to lift 12.5kg (27.55lbs).
When it comes to the grippers picking up parts in automated loading and unloading of machine tools, as well as handling of ferromagnetic raw materials, gripping with magnetic grippers has proven to reduce cycle time and increase production. SCHUNK has addressed this industry need with the new EMH gripper, the world’s first electrically activated, 24 V permanent magnetic gripper with integrated electronics. The new EMH gripper will be showcased in seamless integration with a UR cobot at UR’s FABTECH booth alongside the new UR+ product, the AOV-10 Axially-Compliant Orbital Sander, from ATI Industrial Automation that is the ideal robotic solution for surface preparation and finishing. With built-in compliance, the AOV-10 is well-suited for many different robotic application types—even those that require a light touch.
