SKU: NXB-GEN-ELC412-004 | Version: 1.0 | Brand: NexBot Robotics
The NexBot Robotics ELC412-004 is a versatile two-finger parallel electric gripper engineered for precision handling and assembly tasks in automated industrial environments. This end-of-arm tool provides reliable performance for applications requiring consistent force and position control, such as electronics manufacturing, CNC machine tending, and packaging. Key features include a fully programmable gripping force, adjustable from 5 N up to a maximum of 120 N, allowing for the secure handling of both delicate and robust components without causing damage. The gripper's stroke is 12 mm per finger, providing flexibility for a range of part sizes. Its design incorporates high-resolution position feedback and onboard motion control, which simplifies system integration and eliminates the need for external management hardware. With a positioning repeatability of ±0.02 mm, the ELC412-004 ensures that parts are placed accurately every cycle, contributing to higher production quality and reduced scrap rates. Communication is streamlined via an integrated IO-Link interface, enabling real-time diagnostics, parameter adjustments, and seamless connection to the main robot system. This smart communication protocol provides valuable data on grip status, position, and operating temperature, facilitating predictive maintenance and process optimization. The gripper's housing is constructed from durable, hard-anodized aluminum, and it carries an IP54 rating, making it suitable for deployment in environments with moderate exposure to dust and moisture. Installation is straightforward, utilizing a standard ISO 9409-1-50-4-M6 mounting pattern for direct attachment to compatible NexBot Robotics arm models.
Carefully remove the NexBot Robotics ELC412-004 from its protective packaging. Inspect the anodized aluminum body and M12 connector for any signs of physical damage that may have occurred during shipping. Verify the model number on the device label matches your order.
To configure and operate the gripper, you must first install its IODD file into your IO-Link Master's engineering software. Download the latest version of the IODD file for the NXB-GEN-ELC412-004 from the NexBot Robotics support portal and follow your software's instructions for importing it.
Once the gripper is powered and connected, your IO-Link Master should automatically detect it. Using your configuration software, you can access the gripper's parameters to set its operating mode, speed, force, and stroke limits. You can also view process data such as current position and device status.
The ELC412-004 allows for precise control of gripping force from 5 N to 120 N via an IO-Link parameter. This enables the handling of a wide range of objects, from fragile electronics to robust machined parts. The force should be set to the minimum required to securely hold the object to maximize gripper life and energy efficiency.
The gripper's jaws can be commanded to move to any position within their stroke. This feature is ideal for pre-positioning the jaws before gripping or for applications requiring partial clamping. The gripper provides high-resolution position feedback and maintains a repeatability of ±0.02 mm for precision tasks.
The gripper provides digital feedback bits indicating whether a part has been successfully gripped, if a part was lost, or if the jaws closed without encountering a part. This crucial information allows the robot program to make intelligent decisions, such as retrying a pick or moving to a reject bin, improving overall system reliability.
The opening and closing speed of the gripper jaws is adjustable. Use higher speeds to reduce cycle time in high-throughput applications, and lower speeds to ensure gentle handling of delicate or sensitive workpieces.
The ELC412-004 continuously monitors its internal condition, providing diagnostic data such as device temperature and motor current via IO-Link. Monitoring these values can help predict maintenance needs and troubleshoot errors like over-temperature or over-current faults before they cause a line stoppage.
| Interval | Task | Notes |
|---|---|---|
| Daily | Visually inspect gripper fingers for wear or damage. Check for any debris in the jaw mechanism that could cause binding. | Perform this check at the start of each shift for critical applications. |
| Weekly | Wipe down the gripper housing with a clean, dry, lint-free cloth. Ensure air can circulate freely around the unit. | Do not use compressed air or chemical solvents for cleaning, as this may force contaminants inside or damage the anodized finish. |
| Monthly | Inspect the full length of the electrical cable for signs of abrasion, kinking, or damage, especially at flex points. | An intermittently failing cable is a common source of difficult-to-diagnose faults. |
| Quarterly | Using a calibrated torque wrench, verify that the robot flange mounting screws are tightened to the specified 4 Nm. | Robot motion and vibration can cause fasteners to loosen over time. |
| Annually | Perform a functional test by commanding the gripper through its full range of motion, speed, and force settings. Compare behavior to baseline performance. | Log the results to track long-term performance trends. |
| Every 2 Million Cycles | Re-lubricate the internal drive mechanism according to the official NexBot Robotics service manual. | This procedure should only be performed by a qualified technician using approved lubricant. |
| Symptom | Possible Cause | Solution |
|---|---|---|
| Gripper is unresponsive; status LED is off. | Loss of power or faulty cable. | Use a multimeter to confirm 24VDC at the cable end. Inspect the cable for damage and ensure both ends are securely connected. |
| Gripper has power (LED is on) but does not communicate with the master. | Incorrect port configuration, faulty IO-Link master, or damaged communication line in cable. | Verify the gripper is assigned to the correct port in the controller software. Try connecting the gripper to a different port. Test with a known-good cable. |
| Gripper drops parts during robot movement. | Insufficient gripping force or unsuitable finger surface. | Increase the gripping force parameter via IO-Link. If the problem persists, replace worn finger inserts or use fingers made from a higher-friction material. |
| Gripper movement is slow or seems weak. | Low voltage supply or an over-current condition caused by an obstruction. | Check that the 24VDC supply is not dropping under load. Power down and inspect the jaw mechanism for any foreign objects or debris that may be causing it to bind. |
| A diagnostic fault (e.g., over-temperature) is reported. | Exceeding duty cycle limits, high ambient temperature, or internal component failure. | Review the application's cycle time to ensure it is within the gripper's specifications. Ensure adequate airflow around the gripper. If the fault persists in a cool state, contact support. |
| Gripper position feedback is inaccurate or does not match the actual position. | Loose gripper fingers or an internal encoder fault. | Ensure the gripper fingers are securely tightened to the jaws. Initiate a homing or re-referencing sequence. If the issue remains, the unit may require service. |
| Gripper makes an audible grinding or clicking noise. | Internal gear damage or debris in the drive mechanism. | Immediately stop operation to prevent further damage. Power down and carefully inspect for external causes. The unit will likely require factory service. |
