Foil control in battery manufacturing
Task:
During the manufacturing of Lithium-
Ion batteries, layers of different materi‐
als including copper and aluminum foil
are used. During the application, it is
required to monitor that the Cathode
electrode film is accurately applied to
the copper film. The customer currently
uses cameras, but due to lighting and
reflection, regular re-programming is
needed. The camera also need to be
re-programmed to every different layer‐
ing process, which requires program‐
mers and downtime.
How to ... (Setup and configuration)
Using the AS30, we can easily configure the required detection edge. Doing so, we can
configure the AS30 to detect that the layers are evenly aligned.
An IO-Link, analog out or a simple switching output can be used to align using the
rollers or give an output as soon as a predetermined tolerance level has been
breached.
•
Mount the unit at a slight angle to
avoid reflections
•
Select edge guidance
•
Use Sopas if the reflection influ‐
ences the measurement
