& development
Eight years of research were required to develop
the technological building blocks needed to
develop an integrated solution for automated
structural assembly called LISI#OneSide.
Only one robot to perform complete
assembly sequence
Able to accurately position itself on the structure,
the robot first pre-drills the panels and installs
temporary CLY™62 fasteners to bring together
the two panels and squeeze the sealant present
between them. The final holes are then drilled
and the OPTIBLIND™ blind structural fasteners
are installed while the temporary fasteners
are removed. The selection and transfer of the
fasteners, sealant application onto the fasteners
as well as correct assembly control are done
alongside operations on the structure. The
productivity gain for the aircraft manufacturers
is considerable, since just one robot can work
continuously and autonomously to perform in
parallel a wide number of assembly and control
operations.
Revolutionary blind fastener systems
Anticipated for over 15 years, this major
technological breakthrough was made possible
by overcoming two technological barriers in the
fastening systems: the development of a new
CLY™62 temporary fasteners which is compact
and compatible with robotization and more
challenging the development of OPTIBLIND™
blind structural fastener solution capable of
meeting all relevant areas of performance of
traditional dual access fasteners.
LISI AEROSPACE has been addressing this challenge since 2007, by using a functional
approach to the entire assembly cycle. Following preliminary exploratory phases
(specifications, concepts selection...), the project has been integrated the NexGED
collaborative research program, led by LATECOERE and supported by the DGAC.
The LISI AEROSPACE teams have also relied on KUKA Systems (automation, effector)
competencies for the automation side. This cooperation helped us to develop the
necessary technologies to make a real size technology demonstration, during the
Le Bourget Air Show in June 2015.
