Article

This document provides detailed instructions for the proper installation of the NexBot Drives 813-006 Tool Adapter Plate. This component is critical for mounting End-of-Arm Tooling (EOAT) to the robot wrist. A correct installation ensures mechanical stability, positional accuracy, and the safety of both personnel and equipment. This procedure applies to compatible NexBot articulated robots, such as models in the R-20 and R-50 series.

Failure to follow these instructions may result in improper tool seating, leading to vibration, premature wear, loss of positioning accuracy, or catastrophic failure of the tool or adapter plate during operation.

Prerequisites

Before beginning the installation, ensure you have met all safety, tooling, and environmental requirements.

Safety Precautions

• Lockout/Tagout (LOTO): The robot controller and all related power sources must be de-energized and locked out according to your facility's established LOTO procedures. Verify that all stored energy (electrical, pneumatic, hydraulic) has been dissipated.
• Personal Protective Equipment (PPE): Wear appropriate PPE, including safety glasses and steel-toed boots. Gloves are recommended when handling cleaning solvents.
• Robot Securing: Ensure the robot arm is in a safe, stable position, preferably parked in its home or a designated maintenance position where the J6 flange is easily accessible. If necessary, use mechanical brakes or supports to prevent unexpected movement.

Required Parts and Tools

• Adapter Plate: 1x NexBot Drives 813-006 Tool Adapter Plate (NXB-MNT-813-006)
• Mounting Hardware: A set of appropriate metric bolts (e.g., M6 or M8 socket head cap screws). The required bolt length and grade are specified in the service manual for your specific robot model. Do not reuse old fasteners.
• Tools:
• Calibrated torque wrench with an appropriate socket/drive
• Metric hex key set
• Lint-free cloths
• Isopropyl alcohol or another approved non-residue cleaning solvent

Step-by-Step Instructions

Follow this procedure carefully to ensure a secure and accurate installation.

Step 1: Prepare the Mounting Surfaces

1. Visually inspect the robot's J6 mounting flange. Check for any damage, deep scratches, or burrs that could prevent the adapter plate from sitting flush.
2. Thoroughly clean the J6 flange surface and the mounting surface of the NXB-MNT-813-006 adapter plate. Use a lint-free cloth lightly dampened with isopropyl alcohol to remove all grease, oil, dust, and other contaminants.
3. Allow the surfaces to air dry completely before proceeding.

Step 2: Position the Adapter Plate

1. Carefully align the NXB-MNT-813-006 adapter plate with the robot's J6 flange.
2. The plate and flange will have corresponding dowel pin holes and threaded bolt holes for precise alignment. Gently seat the plate, ensuring the dowel pins (if present on the robot flange) engage correctly with the holes on the plate.
3. The plate should sit completely flush against the flange with no gaps. Do not force the plate into position.

Step 3: Install and Torque Fasteners

1. Insert the new mounting bolts through the adapter plate and into the threaded holes on the J6 flange.
2. Hand-tighten all bolts to ensure they are properly threaded and the plate is evenly seated.
3. Using a calibrated torque wrench, tighten the bolts to the specified torque value. Crucially, refer to the service manual for your specific robot model to find the correct torque specification for J6 flange fasteners.
4. Tighten the bolts in a star or crisscross pattern to ensure even clamping force across the flange. This prevents warping the plate and ensures a secure connection.
5. After the initial torque sequence, perform a second pass in the same pattern to verify all bolts are at the correct torque.

Verification

After completing the installation, perform the following checks before returning the robot to service.

Step 1: Mechanical Inspection

1. Visually inspect the seam between the adapter plate and the J6 flange. There should be no visible gap.
2. Gently attempt to rock the plate by hand. There should be zero movement, indicating a solid and secure connection.

Step 2: Tool Center Point (TCP) Verification

1. The installation of a new adapter plate may slightly alter the tool mounting plane. It is best practice to verify and, if necessary, recalibrate the robot's Tool Center Point (TCP) after this procedure, especially for high-precision applications.
2. Consult your robot's programming manual for instructions on TCP calibration.

Step 3: Return to Service

1. Once all mechanical and calibration checks are complete, remove all tools from the work area.
2. Follow your facility's procedures to remove the LOTO devices and safely re-energize the robot system.
3. Operate the robot at a slow speed to confirm normal motion and ensure there are no new vibrations or unusual noises originating from the J6 joint.

The installation of the NXB-MNT-813-006 Tool Adapter Plate is now complete.
