Optimiert für das Handling von Solarzellen und Wafern: das High Speed H-Portal von Festo


Fast and reliable repositioning thanks to the high-speed planar surface gantry
The fragile wafers frequently need to be repositioned. As they are transferred from one production step to the next, the wafers will be unloaded from a machine and transported to the next processing step. This must be done at maximum speed, and at the same time reliably and accurately in order to maximise the output.

The wafers must be touched as gently as possible in order not to "stress" them. As the wafers have photosensitive surfaces, no residues must remain on their surfaces so that the best use can be made of the light. Permanent checks, which don't interfere with the throughput, complement the repositioning process.


The award-winning high-speed planar surface gantry provides the best solution for this task:
Designed for handling solar cells and wafers, the planar surface gantry covers a rectangular working space with up to 4 degrees of freedom. The Bernoulli gripper has been adapted to transporting the fragile wafers. It ensures smooth, almost contactless transport. The integrated intelligent compact camera checks the wafers for damage and correct alignment.

Gentle and reliable gripping

The application: during the production process, the wafers have to be steadily and reliably picked up and transported through the various production steps. This demands speed in order to keep the production costs of the modules as low as possible. Gentle processing is also required as the wafers must not break.

The challenge: the more the wafer production process progresses, the more refined the wafer is and the more valuable it becomes. Having suitable gripper technology at the right moment is therefore essential for handling the workpieces as well as for reducing investment and energy costs for the machines.

베르누이 흡착컵 OGGB로 그립핑

베르누이 그립퍼 OGGB는 접촉이 거의 없이 웨이퍼를 픽업하고 안정적으로 포지셔닝합니다. 진공 흡착 컵과 달리 베르누이 흡착 컵은 순수한 압축 공기로 작동합니다. 이 공기는 반지 모양의 틈을 통해 통과하게 되어 있으며, 그 결과 웨이퍼를 부드럽고 안정적으로 들어 올리는 흡착 효과가 발생하며, 웨이퍼에 잔류 물이 남지 않습니다.

Monitoring the cooling medium flow in solar and flat-panel production


The manufacturing process for multi-layered solar modules and flat panels generates heat, so a cooling system needs to be integrated into the process. The challenge is to enable reliable monitoring of the flow rate, pressure and temperature of the cooling medium. In vacuum coating processes, for example, the vacuum pumps, generators and the process chamber itself all need to be cooled.


Your objective:

  • A reliable, efficient cooling system
  • Reliable monitoring of the cooling process
  • Less effort and cost for development, commissioning and operation
