Tool attachment for robotic manipulator with rotational engagement
The granted patent US12070849B2 describes a tool attachment designed for robotic manipulators, featuring a housing that securely engages with the manipulator. The attachment includes an input shaft for connection with the manipulator's end effector, an output shaft linked to the input shaft, and a tool affixed to the output shaft. Notably, the housing incorporates mechanisms to prevent relative rotational movement between itself and the manipulator's housing. The design includes a hollow sleeve with a guide portion that facilitates the alignment of the manipulator with the attachment, ensuring efficient operation. The tool attachment can accommodate various tools, including rotary and linear tools, with specific configurations for speed adjustments and movement types.
Additionally, the patent outlines a tool changer system that comprises multiple tool attachments and a tooling basket with mounts for each attachment. This system allows for the selective engagement of tools by the robotic manipulator, enhancing versatility in operations. The tooling basket may feature a carousel mechanism for easy rotation and positioning of the attachments. The method of using the tool changer involves engaging the input shaft of a selected tool attachment, dismounting it from its mount, and remounting it as needed, which can include performing specific actions with the tool. This innovative design aims to improve the functionality and adaptability of robotic manipulators in various applications.
