The key reason for implementing UR cobots was their collaborative safety features. At CATI, a lot of operators work on the shop floor and the company did not want to seclude an area because of the robotic operations. The payload of the cobots was also imperative – the weight of the components manufactured by CATI range from about 1 – 5 kgs. Universal Robots’ largest model, the UR 10, lifts up to 10kgs, making for the perfect tool for CATI’s requirements.
The primary use of the UR10 is loading and unloading a vertical CNC machine. Additionally, the cobot is used for automatic inspection. Here, the cobot places a component on a weighing machine, takes feedback via digital input to decide whether the part meets its weight requirement or not, and then proceeds to sort the component accordingly.
Thus, customers are ensured that they do not receive any faulty components. The cobots, so far, have helped manufacture 40,000 parts, with zero defects or customer rejections.
“We talk about unemployment all over the country but the truth with the SME sector is that we actually can’t find enough qualified labor,” said Prashant Shantaram Umbrani, CEO of CATI. “So, the best combination for us is incorporating robots in our manufacturing, alongside human workers. Smartly combining the number of machines and robots ensures that the payback period will be faster,” said the CEO, recommending his SME fraternity embrace automation. “The time has come for SMEs to automate – robots are no longer the prerogative of large-scale industries only.”
By the time the cobot finishes weighing components from one machine, the second machine is ready with fresh components for the cobot to inspect, making for perfectly timed operations. CATI has already witnessed a 15-20% increase in its production after deploying the UR10, and is aiming for a 30% increase.
