Overview

This technical bulletin details the contents and intended use of the NexBot Robotics 761-004 Maintenance Kit (SKU: NXB-KIT-761-004). This kit is a mandatory component for performing the scheduled 4,000-hour preventive maintenance service on NexBot R-Series articulated robots. Utilizing this kit ensures that certified technicians use factory-specified, genuine NexBot Robotics parts, which is critical for maintaining robot performance, operational safety, and warranty compliance. Adherence to the scheduled maintenance intervals using correct parts minimizes unplanned downtime and extends the operational life of the equipment.

Kit Contents

The NXB-KIT-761-004 is a comprehensive kit containing all necessary consumables for the 4,000-hour service. Each component has been selected to meet the specific demands of the R-Series platform.

• High-performance Axis Lubricant (1 tube): Specially formulated grease for the primary robot axes. This lubricant ensures smooth, low-friction motion and protects critical gear and bearing surfaces from wear.
• System Battery Pack (Lithium): This battery is essential for retaining encoder positions and system configuration data in the robot controller during power-off states. Proactive replacement prevents data loss and lengthy re-mastering procedures.
• Cooling Fan Filter Media (Set of 4): Replacement filters for the main controller cabinet cooling fans. Clean filters are crucial for maintaining proper airflow and thermal management, protecting sensitive electronics from overheating.
• Replacement Fastener Set (Assorted): A curated set of high-tensile fasteners for various inspection covers and access panels. These are intended to replace any fasteners that may show signs of wear, stripping, or corrosion during the service.
• Diagnostic Port Dust Caps (Set of 3): Replacement caps for the primary diagnostic and communication ports on the controller and teach pendant. These caps protect sensitive connection points from contamination by dust, moisture, and debris.
• Lint-Free Cleaning Wipes (1 pack): Professional-grade wipes for cleaning surfaces before applying new lubricant or sealing covers, ensuring a contaminant-free service.

Application Guide

This kit is designed to be used by certified maintenance technicians in conjunction with the official service manual for the specific robot model. The general procedure involves the following stages. Warning: Always follow full lock-out/tag-out (LOTO) procedures before beginning any maintenance.

1. Preparation: Power down the robot and controller system following the documented shutdown procedure. Apply all required safety locks and energy isolation devices.
2. Controller Service:

• Open the main controller cabinet.
• Replace the System Battery Pack. Note the orientation of the old battery before removal.
• Replace the Cooling Fan Filter Media. Remove the fan covers, discard the old media, clean the housing, and install the new filters.

1. Manipulator Service:

• Inspect and clean the lubrication points for each axis as specified in the service manual.
• Apply the High-performance Axis Lubricant to all required fittings and gearboxes. Do not over-lubricate. Purge old grease as directed.
• Inspect all external covers and fasteners. Use the Replacement Fastener Set to replace any damaged hardware.

1. Final Inspection:

• Use the Lint-Free Cleaning Wipes to clean any residual grease from the robot exterior.
• Inspect all communication and diagnostic ports. Install new Diagnostic Port Dust Caps on any ports with missing or damaged caps.
• Close all access panels, torquing fasteners to the values specified in the robot's service manual.

1. Verification: Remove LOTO devices, power on the system, and perform a functional test to ensure all axes move smoothly and the controller reports no new errors.

Affected Robot Models

This maintenance kit is specified for the 4,000-hour service interval on the following NexBot Robotics models:

• NexBot R-20 Series (e.g., NXB-ROB-R20-050-A)
• NexBot R-50 Series
• NexBot R-100 Series

Important Notes

• Always refer to the specific service manual for your robot model for detailed procedures, diagrams, and torque specifications. This bulletin is a supplementary guide and not a replacement for official documentation.
• The use of non-genuine parts may void the product warranty and can lead to degraded performance or catastrophic failure.
• Dispose of the old lithium battery and used lubricant in accordance with local environmental regulations.
