The proper installation and mounting of the NexBot Robotics LA013-007 6-Axis Robot Arm are critical for ensuring its safety, accuracy, and longevity. Due to the significant dynamic forces generated by its 120 kg payload capacity and 2,702 mm reach, the foundation must be prepared to exacting standards. Failure to meet these requirements can result in poor repeatability (exceeding ±0.05 mm), premature mechanical wear, and significant safety hazards.

Answer

To correctly install the NXB-ROB-LA013-007, you must prepare a foundation that meets or exceeds the specifications outlined below. These guidelines ensure the base remains stable under maximum acceleration and payload conditions.

1. Foundation Requirements

The robot must be mounted on a monolithic, reinforced concrete slab. A steel mounting plate can be used but must be securely anchored to a suitable concrete sub-floor.

• Material: Reinforced concrete with a minimum compressive strength of 25 N/mm² (3625 PSI).
• Thickness: Minimum of 200 mm (7.9 inches) of solid concrete.
• Flatness: The mounting surface must be flat to within 0.5 mm over the robot's base footprint (850 x 720 mm).
• Levelness: The mounting surface must be level to within 1.0 mm/m.
• Curing: The concrete must be fully cured for at least 28 days before robot installation.

2. Anchoring Specifications

The robot base must be secured using appropriate chemical or mechanical anchor bolts. The choice of anchor depends on the specific concrete quality and local regulations.

• Bolt Size: M20 high-tensile strength anchor bolts are required.
• Number of Bolts: The robot base has provisions for a specific number of bolts; all mounting holes must be used.
• Embedment Depth: Follow the anchor bolt manufacturer's specifications for minimum embedment depth to achieve the required pull-out strength.
• Torque Value: Tighten the M20 anchor bolts to a torque value of 400 Nm (295 ft-lbs), unless otherwise specified by the anchor manufacturer. Use a calibrated torque wrench and a star or cross pattern for even tightening.

3. Leveling Procedure

Precise leveling is essential for maintaining the robot's specified repeatability.

1. Position the robot base over the prepared mounting holes using appropriate lifting equipment.
2. Place leveling shims or leveling feet (if equipped) at designated points under the base.
3. Loosely install the anchor bolts.
4. Use a precision laser level or machinist's level to adjust the shims or feet until the robot base is perfectly level in both the X and Y planes.
5. Once level, apply a non-shrink grout under the robot base to fill any gaps and provide uniform support.
6. Allow the grout to cure according to the manufacturer's instructions.
7. Perform the final torque sequence on the anchor bolts.

Key Installation Tips

• Vibration Isolation: Ensure the foundation is isolated from sources of heavy vibration, such as stamping presses or large machinery, which can degrade the robot's performance.
• Clearance: Verify that there is adequate clearance around the robot for its full range of motion (2,702 mm reach) and for maintenance access. The robot base itself has a footprint of 850 x 720 mm.
• Power and Data Cabling: Plan your cable routing before final positioning. The NXB-ROB-LA013-007 requires a 400-480VAC 3-Phase power supply and a PROFINET connection. Ensure cables like the NXB-CBL-531-009 have sufficient length and are protected from damage.
