Basic gripping ability

Equipped with the gripping function of standard electric grippers, the gripper fingers are driven to open and close by servo motors or stepper motors, which can stably grip regular workpieces (such as metal blocks, plastic parts), cylindrical workpieces (such as pipes, shaft parts) or perforated workpieces (such as flange plates). The gripping force is adjustable (usually ranging from 5N-500N, and some heavy-duty models can reach several tons), meeting the needs of workpieces of different materials and weights.

Rotation drive function: The gripper body or end effector integrates an independent rotation shaft, which can achieve two rotation modes:

Claw overall rotation: The entire gripper mechanism rotates around an axis perpendicular to the gripping direction (such as horizontally gripping a workpiece and then rotating 90 ° to place it vertically). The rotation angle range is usually 0 ° -360 °, and some models support infinite continuous rotation (such as used in scenarios such as workpiece tightening and winding);

End finger rotation: The fingertip of the gripper rotates independently (such as tightening the bolt by rotating the fingertip after grabbing it), or the gripper rotates synchronously while opening and closing (such as adjusting the angle to align with the assembly hole when grabbing a circular workpiece).

Rotation accuracy and speed controllability

The rotating shaft is equipped with a high-precision encoder or angle sensor, with a positioning accuracy of ± 0.1 ° or even higher. The rotation speed can be adjusted through programming (such as low-speed precise alignment or high-speed rapid flipping) to ensure the accuracy of attitude adjustment.

Structural design and driving method

Integrated structure

The rotating drive module (such as servo motor, gearbox) and the gripping drive module (gripper opening and closing motor) are compactly integrated, avoiding the structural redundancy of the traditional "gripper+external rotating shaft" combination, reducing installation space, and improving overall rigidity (such as when installing the end of a robot arm, lightweight design can reduce load pressure).

Transmission system optimization

The rotating shaft is usually driven by precision gearboxes (such as harmonic reducers, planetary reducers) or synchronous belts to ensure smooth and seamless rotation, and has a certain torque output capability (the rotation torque range is generally 0.5N • m-50N • m), which can drive the workpiece to overcome inertia and complete attitude adjustment.

Multi angle rotation adaptation

Some models support adjustable rotation axis direction, such as rotating around the Z axis (vertical direction), swinging around the X/Y axis (horizontal direction), or multi axis linkage rotation (such as rotating first and then tilting), to adapt to the posture requirements of complex workpieces (such as flipping workpieces from a horizontal conveyor line to a vertical assembly station).

Precise control and intelligent linkage

Programmable Control

By programming preset rotation angle, speed, clamping force and other parameters through the controller or upper computer (such as PLC, robot system), it supports a coherent action sequence of "grabbing → rotation → placement" (such as grabbing the circuit board, rotating 180 ° for back welding, and then placing it at the next station).

Sensor Integration: Some high-end models have built-in force sensors and position sensors to achieve closed-loop control

Monitor resistance during rotation, and automatically stop and sound an alarm if encountering jamming (such as preventing workpiece collision with equipment);

Communication and Compatibility

Combined with the visual system to recognize the initial posture of the workpiece, automatically calculate the required rotation angle (such as rotating to the correct direction through visual guidance after grasping the offset part).

Supports standardized communication protocols (such as EtherCAT, Profinet, IO Link), seamlessly integrates with collaborative robots and automated production lines, and enables remote monitoring and collaborative operations (such as rotating grippers and conveyor belt speed linkage in production lines, synchronously completing workpiece flipping).
