How do you make sure that a product can handle the wear and tear of an expected life cycle and that all safety and quality standards are met? You test it. Over and over again. Nothing is more repetitive than product testing – lending itself to one of the “3D jobs” that robots excel at: dirty, dangerous…and dull. Increasingly, collaborative robots – or cobots - are now being used for product testing.
This type of automation is maximising the testing environment, improving employee productivity and happiness, benefiting the bottom line while allowing companies to bring products to market much faster than ever before.
Take dishwashers, for example. Loading and operating a dishwasher is already a mind numbing job for a human to perform in our regular daily life, so imagine trying to test how many times a dishwasher can be loaded before it wears out?
Scientists from Fraunhofer IPA in Stuttgart, Germany have now developed a mobile cobot system for Bosch Siemens Hausgeräte taking over this tedious task: Universal Robots are programmed to load and operate dishwashers for endurance testing. From putting detergent into the machine to testing the internal baskets, the process is now automated and has delivered many benefits; employees have been relieved of repetitive tasks and the application allows for a standardised and controlled 24/7 operation.
Moving into the lab
The easy assembly, integration, flexibility and precision of cobots means they can be deployed to do intricate tasks including laboratory testing and analysis.
In laboratories, cobots are being used to automate demanding research projects where precision is critical. A robot can consistently and repeatedly follow exact processes and pre-defined workflows with miniscule deviation, providing optimum conditions for study and analysis. This gives scientists and researchers more time to spend on other areas of their project.
Canadian manufacturer of robotic grippers, Robotiq, demonstrates just how efficient it is to deploy a product testing solution with their 2-Finger Adaptive Gripper 85 application. From the installation of the robot and the gripper to programming trajectories, product testing and data collection, the application is easily deployed with little to no downtime in production.
Winning against Chinese competitors
Scott Fetzer Electrical Group in Tennessee uses a Universal Robots UR10 for data collection and life cycle testing of new designs. The cobot is programed to test small motors manufactured by the company, inside customer products. The robot is set to turn the product’s switch on and off, running the motor for a minute, turning it off for 30s and continuing for a period of 400 hours.
During this process the cobot collects relevant data about the quality and performance of the product and the information is transmitted to data storage where it can be analysed. This is an extremely demanding task for employees to undertake and repeat for hours on end with the same level of consistency and precision.
Matthew Bush, Director of Operations, Scott Fetzer Electrical Group, said using cobots in the testing process has been a major benefit for the business.
“It’s enabled us to actually engage our customer in the testing as well; they’re excited to see us use new technology to push our design faster into production. It gives us an advantage over our competitors thousands of miles away in low-cost source countries. We’re now winning orders against Chinese competitors and bringing back work that used to be sourced in China as well.”
Imagine the competitive advantage and opportunities that can be created by automating product testing.
