The end-effector is the terminal component of a robotic arm, serving as the final attachment point that enables the robot to manipulate, grasp, assemble, or process workpieces. As part of the Robotic Upper Handling Module, it acts as the interface between the robotic system and its operational environment, determining the robot's functional capabilities for specific applications. This component is essential in machinery and equipment manufacturing, where precision and adaptability are critical. The end-effector is available in configurations using materials such as aluminum alloy, stainless steel, and engineering plastics, each selected based on application requirements for weight, strength, and durability. Key parameters include payload capacity ranging from 3 to 50 kg, gripping force from 20 to 200 N, stroke length from 10 to 100 mm, and repeatability of ±0.02 to ±0.05 mm. Operating pressure is specified at 0.4 to 0.8 MPa, supply voltage for electric models is 24 V DC ±10%, power consumption is 10 to 50 W, and operating temperature ranges from -10 to 60 °C. The IP rating is IP54 to IP65 per IEC 60529, and the weight ranges from 0.5 to 5 kg. These values are directory reference ranges and must be confirmed for the specific model and application. The end-effector receives mechanical, electrical, or pneumatic signals from the robotic controller to execute precise movements such as gripping, rotating, lifting, or applying force. It translates the robot's programmed motions into physical interactions with target objects. When selecting an end-effector, consider the required payload, gripping force, stroke, repeatability, and environmental conditions. Verify model-specific values and standards with the legal manufacturer or supplier before procurement.
The end-effector receives mechanical, electrical, or pneumatic signals from the robotic controller to execute precise movements such as gripping, rotating, lifting, or applying force. It translates the robot's programmed motions into physical interactions with target objects. The controller sends commands that activate actuators within the end-effector, which then apply the necessary force or motion to the workpiece. For pneumatic models, operating pressure between 0.4 and 0.8 MPa is required; below 0.4 MPa, insufficient force may occur. For electric models, a 24 V DC supply voltage is typical. The end-effector's design ensures repeatable positioning within ±0.02 to ±0.05 mm, enabling consistent operations. Maintenance signals include reduced gripping force, irregular movement, or visible wear on contact surfaces. Failure boundaries are defined by the specified operating temperature range (-10 to 60 °C) and IP rating (IP54 to IP65); operating outside these limits may affect performance or cause damage.
