Robot-Gripped Liquid Coupling With Low-Force Lock Ball Connection

The socket is divided into functionally independent parts: a gripping unit for automated handling and a body for connection. The gripping unit can be held by the robot hand without requiring excessive gripping force, while the connection function is achieved through a separate mechanism involving protrusions and grooves that engage automatically during insertion, eliminating the need for large driving forces.

The invention introduces an intermediary engagement mechanism consisting of protrusions on the socket body and corresponding grooves on the plug. This intermediary structure facilitates automatic connection during insertion without requiring the robot hand to apply excessive force, as the connection is achieved through the geometric interlocking of these features rather than through forceful gripping.

The socket design enables self-alignment and self-engagement during the attachment process. The protrusions on the socket body automatically engage with the grooves on the plug during insertion, and the detection unit automatically detects when connection is achieved. This self-service mechanism eliminates the need for manual manipulation by workers, thereby reducing worker burden and exposure to hazardous liquids while maintaining relatively simple device structure.

The invention incorporates a detection unit that provides feedback on the connection status between socket and plug. This feedback mechanism automatically detects when the protrusions have engaged with the grooves, eliminating the need for workers to manually verify connection status. This reduces worker burden and exposure to hazardous liquids while maintaining simple device structure, as the feedback system uses basic sensors rather than complex control mechanisms.
