Valve Plate
8.7
For enhanced maintenance, the valve plate can be unscrewed and removed. This is where the valves
are located. For cleaning purposes, the attached masking films can be removed so that the spherical
bearings can be removed. In order to ensure that the area gripper continues to work optimally, the
valves must be cleaned regularly, especially when exposed to resins. We recommend replacing the old
masking film with a new masking film during cleaning. If necessary, heavily contaminated bearings can
also be replaced. See chapter 9.9
Here the operator also has the option to make a second, identical plate available for exchange during
maintenance.
Sealing Plate
8.8
Check the sealing plates for wear, tears and leakage on a regular basis and replace them as necessary.
The sealing plates must also be replaced if you notice that the vacuum achieved is constantly declining
when handling the same parts.
Minimum recommended vacuum: 250 mbar when a workpiece is picked up.
For systems that are designed to require higher vacuum, the minimum vacuum must be adjusted ac-
cordingly when the sealing plates are replaced.
The foam may not be cleaned with a compressed-air gun. This would make the
foam permeable to air in the places where compressed air was applied.
If the sealing plate shows mechanical damage, it can be repaired up to a certain
point using standard vulcanizing adhesive (e.g. adhesive for repairing the inner
tubes of bicycles).
Replacing the sealing plates
In order to easily replace the sealing plates, the quick-change plate
can be removed in accordance with the operating instructions. This
means that it is not necessary to replace the sealing plate overhead.
Remove the sealing plate from the quick-change system.
Clean the surfaces. In order to maintain optimal hold of the new seal-
ing plate, the surface must be free of dust, oil, oxides and adhesive
residues.
Remove the protective film from the adhesive strip of the new sealing
plate.
Press the sealing plate firmly onto the entire surface without any
wrinkles (e.g. with a roller).
The openings of the sealing plate and valves must be aligned.
Processing temperature: a range of +10° C to +40° C is recommended for the object tempera-
ture and the ambient temperature.
The sealing mat is asymmetrical. Observe the alignment.
