The ultimate in defect detection
Surface
defects are a significant quality issue for magnet wire producers. Defects
during wire production cost money in scrap and rework, and customer returns
can damage the manufacturer's reputation. Existing solutions are inadequate
for today's high production speeds and in some cases can even damage good
wire.
To address this challenge, Beta LaserMike has launched a leading edge
wire flaw detection system called FlawScan™. With 360° detection
around the wire and the ability to detect flaws as short as 100 microns
long, FlawScan is the ultimate in defect detection. Developed in conjunction
with the Royal Melbourne Institute of Technology in Australia, the system
employs a patented optical measurement technique which is non-contact
and can detect flaws at line speeds of up to 2000 metres per minute. The
surface of the wire is analysed using the latest in digital signal processing.
Optical information on the wire condition is sampled over one million
times per second and high speed filtering techniques are used to identify
product defects. This ensures that surface faults are captured accurately
and consistently, while ignoring changing environmental conditions such
as ambient light and temperature.
