AI Technical Summary

Technical Problem

Existing robot end effector quick-change devices lack a reliable locking protection mechanism, which can lead to connection failure between the tool disk and the main disk, posing a risk of the end effector falling off and reducing the safety and reliability of the production process.

Method used

The pneumatic piston, which uses a wedge-shaped surface design, works with a steel ball to push the steel ball into the limiting groove, thereby locking the tool disk and the main disk together and preventing them from disengaging. Combined with a signal module and a proximity sensor to monitor the connection status, the reliability of the connection is ensured.

Benefits of technology

Even when the power source is interrupted, the wedge-shaped surface can still lock the steel balls, preventing the tool disc from detaching from the main disc, thus improving the reliability and safety of the production process and preventing damage.

Abstract

The application relates to the technical field of end quick-change devices, in particular to an industrial robot end full-automatic quick-change device, which comprises a main disc and a tool disc, the main disc is connected with the external robot end, the main disc is provided with a first cavity, the main disc is fixedly provided with an annular guide column, the annular guide column is provided with a plurality of steel balls, the first cavity is slidably provided with a pneumatic piston, and the contact surface of the pneumatic piston and the steel balls is provided in a wedge shape; the tool disc is provided with a second cavity, the second cavity is fixedly provided with a locking ring, and the locking ring is provided with a plurality of limiting grooves corresponding to the steel balls; the contact surface of the steel balls and the pneumatic piston is provided in a wedge shape, the pneumatic piston is driven by air pressure and pushes the steel balls into the limiting grooves of the tool disc by the wedge surface, the locking of the tool disc and the main disc is realized, when the power source is cut off due to the sudden failure of the robot, the wedge surface can still lock the steel balls in the limiting grooves, damage caused by the separation and falling of the tool disc and the main disc is avoided, and the reliability and safety of the production process are improved.
