Composites Europe 2012 - Electrostatic gripper automates handling of carbon fiber materials

The Fraunhofer IPT is presenting an automated, highly flexible electrostatic gripper system which is capable of lifting semi-finished textile products made of carbon fibers and other materials and putting them down again with pin-point accuracy, without damaging them. The demonstration is part of the joint Fraunhofer-Gesellschaft booth, Hall 8a, Booth A11.
Picking up and depositing carbon-fiber materials automatically

Handling non-rigid, semi-finished products such as woven carbon-fiber mats is technologically a challenging task. So far, the human hand can pick up and deposit a semi-finished textile at a given point, more efficiently than any machine. Accordingly, the manufacture of semi-finished textile goods has traditionally been labor intensive and costly.

The Fraunhofer IPT has therefore developed a gripper system capable of picking up the semi-finished textile product automatically and depositing it as required – more reliably, reproducibly and accurately than a human operative and without damaging the delicate textiles. Electrostatic phenomena are the key. An electric charge is applied to the material. This causes an attraction between the material and the gripper which is sufficiently strong to lift the semi-finished product. Now, for the first time, the electrostatic gripper is also capable of positioning the object in its grasp accurately when it puts it down.
Modular gripper system for a range of manufacturing processes

The gripper can also be constructed in modular fashion. Consequently, it can be adapted to suit virtually any manufacturing process. In conjunction with an adaptive gripper arm and the facility to activate gripper elements individually, it is possible to pick up blanks from a cutting table and lay them down on a curved tool mold, for example. This enables the gripper to handle sheet materials and other flat semi-finished goods as well as carbon fiber materials.

During Composites Europe, The Fraunhofer IPT will present a gripper prototype which will demonstrate the capabilities of the system. The business unit “Lightweight Production Technology” will also present new scope for designing the manufacture of three-dimensional parts in automated tape laying operations as well as fiber-composite product development for medical engineering.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
