REIS SOLAR SYSTEMS LASER SOLDERING

Product Briefing Outline:

Reis Robotics, the system supplier for photovoltaic module lines, has implemented a newly developed laser soldering procedure for practical use with several customers.

PROBLEM

Photovoltaics manufacturers are increasingly anxious to fully exploit the automation potential of their production in order to deal with the increasing demands for lower prices.

SOLUTION

A newly developed laser soldering method ensures further increases in quality, shortened cycle times and reductions in manual rework. An integral process controller monitors and documents the production process.
In doing this, it is possible to concentrate the heat input such that soldering can be done directly on the EVA foil. With direct soldering on the foil, unnecessary multiple handling of the strings during the pre-process is avoided. The integrated process monitors the soldering of each joint individually and the data from this can be transferred and saved in a database for later documentation and quality control. Furthermore, faulty solder joints are reported directly via a monitor at a subsequent work station so that a worker recognizes these immediately and can manually resolder.

APPLICATIONS

The laser soldering system achieves almost half of the total cycle time compared to conventional methods. The high flexibility of the system furthermore allows various module sizes due to fast setting. Features also include high traction forces > 10 N, determined acc. to DIN EN 50461:2006
