Sensor-controlled and flexibly assembled

27.03.2014

Flexible and accurate assembly processes: from 3 to 6 June 2014 the world of automation and mechatronics will be the focus of the Automatica international trade fair in Munich, where scientists from Fraunhofer IPA will demonstrate a sensor-controlled lightweight assembly robot. The goal is to increase the flexibility and cost-effectiveness of assembly processes by using sensors to assist component-specific work-holding fixtures. Workpiece variations and product tolerances can thus be reliably addressed while quality remains unchanged.

Whether for locating workpieces or controlling movements during production processes, fixtures have conventionally been an indispensable element of automation.

Such functions can be realized with maximum flexibility by new-type sensor-controlled robot systems.

Growing cost pressure, short product life cycles and high product diversity call for flexible and cost-effective assembly systems that can, when necessary, be quickly adapted to suit changed requirements. Scientists at Fraunhofer IPA have developed a sensor-controlled assembly process that makes it possible for workpieces to be flexibly positioned without the need for additional work-holding fixtures.

Also, 3D-printed tools ensure fast adaptation of the robot system to suit workpiece-specific geometries. “Our aim with this exhibit is to demonstrate that sensor-controlled robots are capable of coping with modern-day conditions at manual assembly workstations, such as chaotically arranged components,” says Martin Naumann, Group Leader in the Robot and Assistive Systems department at Fraunhofer IPA. “By replacing fixtures with sensors, we offer flexibility at low cost,” adds Naumann.

Exhibit at trade fair

Fraunhofer IPA’s stand at the trade fair will demonstrate sensor-controlled assembly in a robot cell with the KUKA LBR iiwa. “The cell will showcase the example of how to bolt a clutch onto the crankshaft of a chain saw.

However, the underlying concepts can equally well be applied to many other products and assembly processes. We’re highly interested in transferring the exhibited solution to new applications,” explains Naumann. The clutch for mounting on the crankshaft is placed within the robot’s workspace without the need for a separate work-holding fixture.

The robot moves to the determined location of the clutch and localizes the exact position of the component using an additional camera integrated in the robotic tool.

The mounting position of the clutch on the crankshaft is localized in the same way, which means that the engine block can also be flexibly positioned anywhere within the robot’s workspace. The clutch is slid and bolted onto the crankshaft with precision force control, which allows any errors during bolting on, such as tilting, to be detected and immediately corrected.

Im Focus: Energy-autonomous and wireless monitoring protects marine gearboxes

The IPH presents a solution at HANNOVER MESSE 2015 to make ship traffic more reliable while decreasing the maintenance costs at the same time. In cooperation with project partners, the research institute from Hannover, Germany, has developed a sensor system which continuously monitors the condition of the marine gearbox, thus preventing breakdowns. Special feature: the monitoring system works wirelessly and energy-autonomously. The required electrical power is generated where it is needed – directly at the sensor.

As well as cars need to be certified regularly (in Germany by the TÜV – Technical Inspection Association), ships need to be inspected – if the powertrain stops...

The Atlantic overturning is one of Earth’s most important heat transport systems, pumping warm water northwards and cold water southwards. Also known as the Gulf Stream system, it is responsible for the mild climate in northwestern Europe. 

Scientists now found evidence for a slowdown of the overturning – multiple lines of observation suggest that in recent decades, the current system has been...

Im Focus: Robot inspects concrete garage floors and bridge roadways for damage

Because they are regularly subjected to heavy vehicle traffic, emissions, moisture and salt, above- and underground parking garages, as well as bridges, frequently experience large areas of corrosion. Most inspection systems to date have only been capable of inspecting smaller surface areas.

From April 13 to April 17 at the Hannover Messe (hall 2, exhibit booth C16), engineers from the Fraunhofer Institute for Nondestructive Testing IZFP will be...
