7 Maintenance and Care
The robot coupling is designed for low-maintenance operation, so
that opening and disassembling is only necessary in exceptional
cases.
CAUTION
Risk of injury and risk of damage to the robot coupling when
opening the housing cover.
If the robot coupling has to be disassembled, send the module
to SCHUNK for repair.
The cover of the robot coupling is spring preloaded and must
only be removed by trained specialist personnel.
To ensure the robot coupling operates perfectly, the following
instructions are to be observed:
Pressurizing medium, compressed air. Requirement for
compressed air quality according to ISO 8573-1: 6 4 4
A separate maintenance unit must be used for the air supply. The
robot coupling is prepared for use with unlubricated compressed
air.
• Make sure that the contact surfaces of the interface are always
clean.
• Make absolutely sure that no chips of any kind can enter the
interface and that the interface does not fill with cooling
emulsion, which is particularly possible with vertical alignment
of the clamping pin axis. If the interface should fill with cooling
emulsion, initiate the unlocking process and dry out the
interface in actuated state.
• Only use high-quality cooling emulsions with anti-corrosive
additives during processing.
• Check the robot coupling at regular intervals (at least every two
weeks or after 1000 clamping operations). The system is
functioning correctly if the clamping slides move smoothly at
minimum system pressure (5 bar).
7.1 Regular Inspection of Robot and Pallet Coupling
A visual inspection of the robot coupling and the associated PKL
pallet coupling for possible damage to the components must be
carried out at regular intervals.
This visual inspection must be
carried out every 50,000 clamping cycles.
A leak test must be carried out on the robot coupling every
50,000 clamping cycles.
During a leak test, the air and plug-in connections, along with the
entire clamping system, are to be tested for leaks and significant
