Planning and Design

Accelerated wear conditions: long-term temperature limit operation, abrasive dust environment, sustained performance limit, single axis high duty cycle, monotonic reciprocating short stroke, wrist long-term static, external process force; If the above working conditions occur, KUKA must be consulted to shorten the maintenance cycle; The robot has built-in overheating and overload monitoring, and automatically shuts down when exceeding the limit.

Two installation base schemes

Centering option base S310: concrete floor; Concrete grade C20/25; Bottom plate, chemical anchor bolt, positioning pin; Basic section drawings prohibit adding sound insulation leveling layers between the base and concrete.

Rack mounted installation: installed on the customer's steel structure and KUKA linear slide table; 4 M20 bolts+2 locating pins; Strict requirements are placed on the flatness, roughness, and structural stiffness of the installation surface.

Cable planning: The minimum static bending radius for motor cables is 150   mm, and for signal cables it is 60   mm. Power cables and signal cables are laid separately in metal cable trays to achieve EMC electromagnetic compatibility; Double protection grounding; Cable layout eliminates tripping risks; Cables are prohibited from withstanding tensile forces.

A1 Base Interface Definition: Motor X30/XD30, Data X31/XF31, Mastering Calibration Interface, External Shaft Interface Drawing.

Transportation

Forced transportation posture (maintain throughout the transportation process, do not change the posture before fixing to the base to prevent tipping)

A1=0°，A2=‑138°，A3=139°，A4=0°，A5=90°，A6=0°

Shipping Method

Forklift: Optional fork slots need to be installed;

Crane: Use KUKA specialized lifting equipment and M10 lifting rings, with lifting points distributed around rotating columns and bases;

Prohibit lifting from non-standard lifting points; Avoid impact and vibration; Remove the lifting ring/hoist after it is in place; Provide the overall dimensions and center of gravity position for the transportation of the entire machine.

Startup Debugging and Restarting

The complete process of covering the installation of fixed base flooring, rack mounted flooring/wall mounted/suspended ceiling.

Prerequisite: The robot is in a transport position, the base steel structure is completed, and the lifting equipment is in place.

General installation steps:

Lift into place and install the positioning pin;

M20 bolts are tightened diagonally in multiple stages to the specified torque;

Connect dual protection grounding (torque 23 Nm);

Connect motor cables and data cables; The sound of a click on the connector indicates locking, and the lock buckle can rotate 90 degrees to prevent accidental unlocking;

Fill in the actual installation posture and inclination angle of the robot using WorkVisual software;

Install tools, power on, jog in T1 mode, perform axis Mastering zero calibration, and perform overall functional testing.

After 100 hours of operation, all anchor bolt torques must be rechecked.

Maintenance

Only allow maintenance projects recorded in the manual to be executed; The remaining repairs will be entrusted to KUKA authorized personnel; Emergency stop, lock and power off before maintenance; The maintenance cycle needs to be shortened when the operating oil temperature exceeds 60 ℃; Maintaining in a clean room environment can compromise the cleanliness level.

Maintenance cycle summary table

Periodic homework content consumables

After being put into operation, only one 100 hour recheck of the torque of all bolts on the base will be conducted

5000 hours visual inspection of A1 flexible pipeline package for damage -

10000   h A1 cable package coated with lubricating grease PETAMO GHY   133   N

20000 hours or at the latest 5 years, A1-A6 axis gradual flowering key inspection and fat supplementation; Change all gearbox oil Cassida Fluid GL150 gear oil; Microlube GL261 grease; Drei Bond 5204HV sealant

Suggest KUKA to conduct a comprehensive on-site inspection of the entire machine after 7 years or changes in operating conditions.

Key maintenance process

A1 cable package lubrication: Remove the base cover plate, visually inspect the corrugated tube, apply lubricating grease with a brush, restore the cover plate, and jog A1 to evenly distribute the grease.

Gradual flowering key inspection and lubrication of each axis motor (A1-A6)

Before disassembling the motor, the corresponding shaft must be mechanically locked with a sling fixture to prevent the arm from falling;

Remove the motor, clean the gradually blooming key, and check for wear and tear; Damage must be replaced; Thin and continuous application of Microlube GL261;

Apply Drei Bond 5204HV to the O-ring/sealing surface; tighten the bolts diagonally in steps; Connect the plug back; The axis must undergo Mastering zero calibration.

The disassembly of A6 motor is complex, requiring the removal of A4 and A5 motors first, followed by the removal of the entire straight arm before the A6 motor can be removed.

General rules for gearbox oil change: The gearbox is at operating temperature; Measure the actual amount of oil released during oil discharge; If the oil release rate is less than 70% of the rated value, the gearbox needs to be flushed; Rinse twice with less than 50%, and move the entire stroke during rinsing; Magnetic plug inspection for metal debris; Tighten the plug according to the specified torque; Oil change completed T1 mode jog operation, check for leaks.

Initial oil filling amount for each gearbox: A1=1.20   L; A2=0.80   L; A3=0.32   L; A4=0.32   L; A5/A6=0.37   L.

Robot cleaning: Prohibit high-pressure water guns and direct blowing of compressed air on bearing seals; Use water-soluble neutral cleaning agents; Power off operation to prevent liquid from entering the electrical chamber.

Maintenance

General safety for motor replacement: power off, lock the main switch, wait for 5 minutes for high voltage discharge; Before disassembling the motor, the corresponding shaft must be mechanically locked to prevent the arm from accidentally falling;

Motor installation: Check that the gradual flowering key is not damaged and apply Microlube GL261 evenly; The O-ring seal must be replaced if it is damaged; Tighten the bolts diagonally in steps; After installation, the axis must undergo Mastering zero calibration and T1 mode trial operation.

Special difficulties:

Dismantling of A2/A3 motors, fixing the connecting rod arm/boom with a sling to prevent self weight from falling;

A6 motor: The A4 and A5 motors must be removed first, and the entire straight arm must be dismantled before the A6 motor can be removed;

Replacement of straight row wrist assembly: It is necessary to remove the A4/A5/A6 motors and the lifting device supporting the wrist (about 23 kg) in sequence, and disassemble and replace the entire set.

Overview of Electrical Wiring; Repairs must use KUKA original spare parts; Complete verification of all safety functions after maintenance is completed.
