PV module assembly

For the complete PV module assembly line, Stäubli's advanced four-axis and six-axis robots meet the challenges of the growing industry. The module assembly begins usually by cutting pre-treated cells into pieces followed by the stringer application. The Stäubli TS2 SCARA robots allow the highest throughput of such process on the market thanks to their unparallel speed and precision. When it comes to the following processes such as string layup, frame assembly and module handling for treatment and packaging, our large payload 6 axis robots, TX2-160 and TX200, provide the best precise positioning and long-term reliability.

Automation solutions for the entire module assembly

Automation solutions for the entire module assembly

Laser cutting

Solar cells are at first cut into 2 or 3 pieces in a laser cutting machine equipped with Stäubli TS2 for high speed and high precision cell loading/unloading


Tabber and stringer

Stringer machines equipped with high speed Stäubli TS2 robots are widely appreciated by module manufacturers, with a throughput of more than 7000 cells per hour, ranking top worldwide.


String layup

In string layup application, the Stäubli TX2 robots ensure the smooth movement of cell strings to be assembled.


Framing and junction box assembly

The Stäubli TX2 robots provides the long-term reliability and precise positioning in applications of framing and junction box assembly.


Module test, sorting and packaging

The heavy payload TX200 ensures the large working envelope and smooth handling of the final solar modules for test, sorting and packaging.

Robotics user’s requirements


It allows a lowest breakage rate and far less downtime of the equipment.


Because a high throughput is the key in applications like stringer.

Long-term reliability

The robot should always have the best performance after years of usage.


Because robot is not working alone. Tracking devices, Imaging devices are all connected.
