Fast, gentle, reliable and precise: these are the attributes that characterise the economical production of flat panels. Festo offers interesting products and solutions for all your requirements, whether for plastic rubbing, seal printing, separating or for grinding edges.
Project and solution highlights
Soft and gentle lifting of substrates
The vertical transport of fragile, heavy thin-film modules presents a challenge: despite the high moving load, gentle and even movement must be achieved in order to prevent damage. The high moving load often pushes traditional spindle systems to their limits. These challenges are perfectly mastered by lifting systems from Festo.
The challenge: heavy weight, maximum speed, and an even and gentle movement
Lifting systems from Festo meet these requirements. By cleverly combining pneumatic and electric drives, the advantages of both technologies are optimised for the application. The pneumatic axis DGC balances the weight, while the electric axis EGC with toothed belt drive controls the movement. This ensures that the glass is transported both quickly and gently.
- The benefits of having two technologies from a single source optimise the performance during transport
- A significant reduction in motor and controller sizes compared to spindle solutions
Quick and precise dispensing
Precision is required when applying the adhesive track. Insufficiently applied conductive adhesive doesn't guarantee sufficient contact; too much adhesive can result in short circuits. Speed is also an important issue for competitive production. The application must also be able to deal flexibly with the variation in glass formats.
Optimally adapted handling solution for quick and precise dispensing
Two independently positionable dispense heads that operate in parallel carry the adhesive beads onto the thin-film cells. Thanks to the precision of the axes, the adhesive beads are accurate to within 0.2 millimetres. Track length, track distance, formulas, etc. are freely programmable.
Exact and precise: the two dispense heads that operate in parallel can be positioned via independently functioning X-axes.
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.
