Complementary Gripper Arms for Sample Tube Rack Handling

The automated handling system performs rack manipulation tasks autonomously without requiring manual intervention. The gripper device with complementary gripping surfaces automatically grasps, transports, and positions racks, allowing the system to serve itself rather than relying on human operators for repetitive handling tasks.

The patent replaces manual mechanical handling with an automated mechanical gripper system. The gripper device uses mechanically complementary surfaces to engage with corresponding rack features, substituting human hand operations with a controlled mechanical system that can safely and efficiently handle racks at operating heights.

The gripper device features locally adapted gripping surfaces with specific geometries that match corresponding features on the rack surfaces. Rather than using a uniform gripping mechanism, the patent implements customized contact surfaces at specific locations on the gripper arms that complement the unique geometry of each rack type, ensuring reliable engagement.

The patent employs asymmetric gripping surfaces on the gripper arms that correspond to the asymmetric geometry of the rack surfaces. The complementary asymmetric features enable selective and secure gripping of racks with specific geometries, preventing slippage or misalignment that would occur with symmetric or generic gripping mechanisms.

The alignment element uses asymmetric geometric features including inclined surfaces and complementary shapes that naturally guide the rack into proper alignment during the placement process. The asymmetric geometry of the alignment element corresponds to the asymmetric rack surfaces, creating self-aligning contact that ensures precise positioning without requiring complex active alignment mechanisms.

The alignment element enables the rack to self-align during placement through its geometric features. As the rack is positioned on the alignment element, the complementary asymmetric surfaces automatically guide the rack into the correct orientation and position, eliminating the need for external alignment adjustments or complex control systems.
