QUARTERLY ROBOT PALLETIZER MECHANICAL L3
Maintaining a robot palletizer at Mechanical Level 3 (quarterly PM) is important because it addresses deeper mechanical components that directly affect safety, reliability, and efficiency. Quarterly Mechanical L3 maintenance ensures the palletizer remains safe, reliable, accurate, and long-lasting, supporting continuous and cost-effective operations.

QUARTERLY ROBOT PALLETIZER MECHANICAL L3
Maintaining a robot palletizer at Mechanical Level 3 (quarterly PM) is important because it addresses deeper mechanical components that directly affect safety, reliability, and efficiency.

FANUC ROBOT
Confirm the controller ventilation system is not dusty. If dust has accumulated, remove it.
Check the external damage or peeling paint
Check whether the robot has external damage or peeling paint due to the interference with the peripheral equipment. If an interference occurs eliminate the cause. Also, if the external damage is serious, and causes a problem in which the robot will not operate, replace the damaged parts.
Check for damage of the cable protective sleeve
Check the mechanical unit cable protective sleeves for holes or tears. If damage is found, replace the cable protective sleeve. If the cable protective sleeve is damaged due to interference with peripheral devices, eliminate the cause, ⇒”7.2.3 Check the Mechanical Unit Cables and Connectors”
Check the wear debris of the J1-axis swing stopper
Check whether wear debris has accumulated on the J1-axis swing stopper rotation part. If serious wear is evident on the part that generated the wear debris, replace the part.
Check for water
Check whether the robot is subjected to water or cutting oils. If liquid was found, remove the cause, and wipe off the liquid.
Retightening the end effector mounting bolts
Retighten the end effector mounting bolts. Refer to the following section for tightening torque information: ⇒ 4.1 END EFFECTOR INSTALLATION TO WRIST
Retightening the external main bolts
Retighten the bolts which are installed, removed in the inspection, and exposed. Refer to the recommended bolt tightening torque guidelines at the end of the manual. Some bolts are attached with adhesive. If the bolts are tightened with greater than the recommended torque, the adhesive might be removed. Therefore, follow the recommended bolt tightening torque guidelines when retightening the bolts.
Check the mechanical stopper and the adjustable mechanical stopper
Check that there is no evidence of a collision on the mechanical stopper, the adjustable mechanical stopper, and check that the stopper mounting bolts are not loose. Check that the J1-axis swing stopper rotates smoothly. ⇒”7.2.4 Check of Fixed Mechanical Stopper and Adjustable Mechanical Stopper”
Clean spatters, sawdust and dust
Check that spatters, sawdust, or dust does not exist on the robot main body. If dust has accumulated, remove it. Especially, clean the robot movable parts well (each joint, and the cable protective sleeve).
