[0002] Driven by the wave of science and technology, we are in an era of rapid development of intelligent production. The industrial field, especially the production method, is undergoing unprecedented profound changes. One of the important drivers of this change is the widespread application of industrial robotic arms.
[0003] Industrial robotic arms rely on sophisticated sensors and algorithms to achieve accurate and error-free operations. Their efficient working ability and stable performance have made traditional manual operations gradually disappear from the historical stage. This transformation not only greatly improves production efficiency, but also reduces errors and safety hazards caused by human factors.
[0004] However, although the application of industrial robotic arms has achieved remarkable results, they still have certain limitations in some aspects. In particular, in the installation of the clamping jaws, the flange on the clamping jaws needs to be precisely aligned with the flange on the industrial robotic arm, and then the bolts pass through the mounting holes on the two flanges and cooperate with the nuts to firmly fix the clamping jaws on the industrial robotic arm.

This means that when the gripper needs to be replaced to adapt to different types of industrial robot arms, the corresponding flange also needs to be replaced. This process is not only cumbersome to operate, but also not conducive to rapid installation and debugging. In the pursuit of efficient and flexible modern industrial production, this limitation has obviously become a bottleneck restricting the further role of industrial robot arms.
