The LCD production machine (LCD is short for liquid crystal display) is a high-tech machine for the manufacture and inspection of liquid crystal display or liquid crystal screens. The special challenge here was: The machine uses a five-axis microscopic system to measure the three-dimensional geometry of the liquid crystal molecules within a pixel in an 8K LCD display. These machines are used on the world’s largest LCD production line.

Axometrics requires a high-quality vibration decoupling for these machines. The objective was to protect the integrated microscope in particular from vibration. This is the only way to reliably ensure high-resolution inspection and correct vibration-free measurement results. In addition, the Bilz solution should be repeatable, and trouble-free application should also be possible at future production sites.

Customised solution from six standard air springs BiAir® 3-ED/HE

Bilz developed a customised solution with six standard air springs BiAir® 3-ED/HE. A BiAir® membrane air spring isolator consists of turned aluminium or cast aluminium in which the air volume is enclosed by a thin-walled, flexible and pressure-resistant rolling membrane. The piston sits on the diaphragm and is pushed into the air volume. This constructive design enables highly effective vibration isolation. In addition, the powder coating makes this solution clean-room compatible, an important requirement for Axometrics.

The vibration-isolated storage of highly sensitive and very heavy high-tech equipment is our speciality.

"Here too, our standard BiAir® air springs and our highly precise pneumatic level controls make the difference.
