Robot gripper and operating method

Robot gripper for simultaneous gripping of connectors by combining plug and wire grippers

This technology features a mechanism where plug and wire grippers are spaced apart on the first and second gripper bodies of a robot gripper, sliding along a rail to simultaneously grip and press both the plug and its connected wire.

Conventional parallel jaw grippers suffer from limited gripping surface area for electrical connectors, poor compatibility due to connector size variations, and risks of movement path restrictions or connection damage caused by exposed wires.

This technology separates the plug and wire gripping sections and uses first and second pressure plates to secure the plug. By setting the hardness of the plug gripping surface lower than that of the wire gripping surface, it enhances gripping stability and achieves variable-width gripping through sliding rail actuation. It can be applied to manufacturing assembly, electrical automation, and industrial robotics, increasing assembly process efficiency by simultaneously gripping connectors and wires of varying specifications.

Key Features:

• A plug gripping unit comprising a first plug gripper and a second plug gripper spaced apart from the first, configured to grip a plug in the space between them.
• A pressure unit consisting of a first pressure plate in contact with one side of the plug, and a second pressure plate positioned between the second plug gripper and the second wire gripper, also in contact with one side of the plug.
• A wire gripping unit comprising a second wire gripper configured to grip the wire connected to the plug in the space between it and the first wire gripper.
• A plug gripping unit comprising a second plug gripper configured to grip the plug in the space between it and the first plug gripper.
