Overview

The NexBot Drives 641-006 Robot Floor Mounting Plate (NXB-MNT-641-006) provides a stable, level, and secure foundation for compatible NexBot industrial robots, including models from the R-50 and R-100 series. Proper installation is critical for ensuring robot accuracy, repeatability, and long-term operational safety. This guide outlines the standard procedure for installing the 800 x 800 x 38 mm mounting plate onto a prepared concrete surface.

Failure to follow these instructions may result in poor robot performance, premature wear of mechanical components, or a catastrophic failure of the mounting system.

Prerequisites

Before beginning the installation, ensure all prerequisite conditions are met.

1. Safety

• All personnel involved must wear appropriate Personal Protective Equipment (PPE), including steel-toed boots, safety glasses, and work gloves.
• The work area must be cordoned off to prevent unauthorized access.
• Ensure any nearby equipment is de-energized and follows proper Lockout/Tagout (LOTO) procedures.
• Use certified and appropriately rated lifting equipment (e.g., overhead crane, forklift with rigging) to handle the mounting plate. The plate's weight requires mechanical assistance.

2. Site Preparation

• Floor Condition: The concrete floor must be fully cured, clean, and free of debris, oil, and moisture. The concrete must meet the minimum thickness and compressive strength requirements specified in the robot's facility planning guide. The surface should be flat and level.
• Layout: The final position of the mounting plate must be clearly marked on the floor according to the approved robotic cell layout drawings. Establish reference lines (centerlines) for accurate placement.

3. Required Components and Tools

• Mounting Plate: Verify you have the correct part: NXB-MNT-641-006.
• Anchor Bolts: Procure high-strength chemical or mechanical concrete anchor bolts. The size, length, and type must be selected by a qualified structural engineer based on the robot model, payload, dynamic loads, and floor specifications.
• Tools: A complete list of tools can be found in the 'Tools Required' section of this document.
• Grout (Recommended): High-strength, non-shrink grout to ensure complete contact between the plate and the floor.

Step-by-Step Instructions

Step 1: Position the Plate

1. Carefully lift the NXB-MNT-641-006 mounting plate using appropriate lifting equipment.
2. Lower the plate into position, aligning it precisely with the reference lines marked on the floor. Use the alignment marks on the plate if present.

Step 2: Mark and Drill Anchor Holes

1. With the plate in its final position, use a paint marker or scribe to mark the center of each anchor hole onto the concrete floor.
2. Carefully move the plate aside to expose the marked locations.
3. Using a hammer drill and a correctly sized concrete drill bit (as specified by the anchor bolt manufacturer), drill the anchor holes to the required depth.
4. Thoroughly clean each hole of all dust and debris using a wire brush and compressed air. This step is critical for achieving the anchor's specified holding strength.

Step 3: Secure and Level the Plate

1. Reposition the mounting plate over the drilled holes.
2. Install the anchor bolts according to the manufacturer's instructions. For chemical anchors, follow the specified procedure for injecting the adhesive and inserting the studs.
3. Hand-tighten the nuts initially.
4. Place a precision level (spirit or laser) across the top surface of the plate. Use leveling nuts on the anchor bolts or steel shims to level the plate. Adjust until the plate is perfectly level in both X and Y axes within the tolerance specified in the robot manual.
5. Once the plate is level, use a calibrated torque wrench to tighten the anchor bolt nuts in a star or crisscross pattern to the torque value specified by the anchor bolt manufacturer.

Step 4: Grout the Plate (Recommended)

1. To provide uniform support and dampen vibration, it is highly recommended to grout the space underneath the mounting plate.
2. Build a small form or dam around the perimeter of the plate to contain the grout.
3. Mix the non-shrink grout according to the manufacturer's instructions to a flowable consistency.
4. Pour the grout into the designated grout holes on the plate or from one side, ensuring it flows evenly to fill all voids beneath the plate. Use a strap or rod to help distribute the grout and release any trapped air.
5. Allow the grout to cure for the time specified by the manufacturer before proceeding.

Verification

After the installation is complete and the grout (if used) has fully cured, perform the following checks:

1. Levelness: Re-verify that the top surface of the NXB-MNT-641-006 plate is level to within the required engineering specifications.
2. Torque: Re-check the torque on all anchor bolt nuts to ensure they have not loosened.
3. Position: Confirm the plate's final position and orientation match the cell layout drawings.

The mounting plate is now ready for the installation of a NexBot R-50 or R-100 series robot.
