4.3.4 Release Residue Pressure in Cavity
Operate the robot properly to release the residue pressure in the cavity after injection. Install a
recyclable bag under the inlet and outlet port to avoid lubricant splashing.
To release the pressure, keep the outlet port open, J1 axis within the range of
±
30
°
, J2/J3
axis within the range of
±
5
°
, J4 axis and J6 axis within the range of
±
30
°
, move for more than
twenty minutes in low speed state.
If the above movement cannot be performed due to surrounding situations, the robot should be
operated for the same number of times (When the axis angle can reach half, operation time should
be twice the original time). After the above movement is completed, install sealing screw plug with
combination pad or sealing tape on the outlet port.
4.4 Timing Belt Maintenance
Because the J5 and J6 axes are both driven by timing belt, operation for a period of time may cause
loosening and decline of performance precision. The timing belt may also be worn and cracked. If it is not
replaced and maintained, transmission failure and economic loss may occur. Therefore, it is recommended
to check the running state of the timing belt regularly (every half year). The loosening part should be
tightened and the damaged should be replaced to ensure the transmission precision and stability of the
timing belt.
