Tiny solution to welding precision
May 1st 2007 MacGregor Welding
Systems' latest automated
assembly system, is
designed to fabricate
miniature sensor modules
for use in analyser
equipment. It takes
individual component parts
and assembles them
completely automatically –
a process that involves the
precision welding of
metallic connector ribbons
onto small pins.
The system makes
extensive use of Festo
electrical and pneumatic
actuators, including two
electrical mini slide units
with matching controllers,
which are fed with position
feedback data to ensure
high accuracy assembly
and precision micro
welding. Graham
MacGregor, MD, explains
"We elected to use Festo
SLTE mini slides primarily
because they provide a
complete, ready-to-run
positioning solution. The
slides incorporate their own
miniature motors which
simplifies system integration
and makes them very cost
effective, and the supplied
control software is
extremely easy to use."
One of the mini slides is
associated with the initial
product assembly stages,
the other with the welding
stage. More articles from Festo Limited: |
