2BG Srl has extended its product line with the complete automation of bussing soldering process in order to meet the high demand of quality production and throughput. The IC200AR is an in-line system that’s operates as a robotic workstation which solders bus ribbons to solar cell strings for completing the electrical interconnection of the module prior to lamination. It is positioned after the strings layup and enables a high-degree of automation in the panel assembling line.

The bussing process is a very critical step of whole assembling process and is closely related to the final product quality and efficiency of panel. For this reason in the manual bussing station is important to choose very skilled operators with soldering iron. In any case the manual process cannot guarantee repeatability and stable results with fixed cycle time.
Solution
Wire preparation and placement are done with high accuracy by robots with special tools and devices. Particular attention has been paid with the choice and integration of soldering technology and vision camera with the purpose to assure the best combination of performance and reliability, reaching cycle time of 80 sec for each of 72- cell module. The workstation prepares and welds ribbon bussing strings to complete the electrical circuit before the module lamination. With the new automatic bussing station, solar cells are not subject to mechanical stress due to the high quality of soldering without heating and has the precision required for identifying the welding points.
Applications
Automation of strings bussing soldering process.
Platform
The IC200AR is an in-line system based around a robotic workstation, using advanced soldering technology and the vision system.
Availability
January 2010 onwards.
