Common Faults and Treatment
The fault of manipulator may be caused by a number of different reasons. It is
often difficult to thoroughly find out the cause. If the wrong handling method is
used, the fault may be further deteriorated. Therefore, it is very important to
analyze the fault situation and find out the real cause. The possible fault and
causes of manipulator are as shown in
. If you are unsure of the cause
or do not know how to proceed, please contact us
Table 14-1 Possible Faults and Causes of Manipulator
Fault
Classification
Possible Causes
Treatment
Vibration
Abnormal noise
◼
When the manipulator
operates, its base floats from
the workshop pedestal
◼
There is a gap
between the base and
workshop pedestal
◼
The screws connecting
the base and workshop
pedestal are loose
Fixation of Base:
1. The manipulator base is
not firmly fixed on the
workshop pedestal
2. The base floats from the
workshop
pedestal
and
generates the vibration when
the manipulator acts due to
the
screw
looseness,
insufficient flatness of base
and the foreign objects.
1. When the screw is loose,
tighten it with the torque
wrench according to the
proper torque
2. Trim the base flatness in
accordance with the tolerance
3. Check if the foreign matters
are trapped, and if so, remove
them
4. Please consult with us
◼
Workshop
pedestal
vibrates
when
the
manipulator acts
Workshop Pedestal:
1. Pedestal is not completely
fixed on the foundation.
Therefore, the workshop
pedestal vibrates when the
manipulator acts.
2. The insufficient rigidity of
workshop pedestal, and the
reaction force and torque
generated by the manipulator
cause the deformation and
vibration.
1.
Completely
fix
the
workshop pedestal according
to the corresponding method
2. Workshop pedestal shall be
processed to improve its
rigidity
3. For the workshop pedestal
with machining difficulty, the
vibration may be mitigated
through the modification of
moving program
