Tabber and stringer TS1400

Very flexible Tabber&Stringer, can make standard modules or special modules with cut cells, for example, very easy to handle and economical with a medium-high production capacity of >40MW/year.

Description

Mondragon Assembly’s Tabber&Stringer is easy to operate, precise and reliable. By just changing a few parameters, we can immediately change the string.

Thanks to our knowledge and experience in technological processes and solar equipment, our team offers modular designs with advanced functions, low cost and high performance.

The Tabber&Stringer has four main remarkable elements: Cell quality control using artificial vision, advanced control of the IR soldering process, servo-drives and up to 5 bus bar ribbon power systems

Advantages

Vision control systems to see the quality of the cells so that defective cells can be detected and removed.
Control of cell temperature to ensure good soldering.
Time control for correct self-diagnostics.
Unlimited number of process formulas, where the same model or module can assume different process parameters, depending on the materials used.
Flexibility for processing different cell models or sizes with a very short change time. We work with cut cells. Up to 1/6 of 6” cells.

Main features

Contactless IR soldering so that no stress is generated in the cell.
Flux dispensing onto the bus bar without contact with the cell.
Anti-camber systems to improve the ribbon’s alignment.
Artificial vision
