AI Technical Summary

Technical Problem

Existing robot grippers have poor adaptability when dealing with various types and specifications of products, making it difficult to quickly change gripping components. Furthermore, sensor installation is complex and maintenance operations are demanding.

Method used

Design an underactuated rigid-flexible coupling gripper, in which a flexible component and a sensor are mounted on a groove in a first flexible rod. The gripper is connected to the flexible rod via a hinge structure, and a drive mechanism controls the movement of the gripper to achieve adaptive gripping.

Benefits of technology

The gripper is highly adaptable and can quickly change the gripping parts. The sensor flexibly adapts to different object surface shapes, resulting in high production efficiency and good gripping stability.

Abstract

本发明涉及一种用于装配的欠驱动刚柔耦合夹持器,包括固定架、驱动机构和夹持机构,所述夹持机构包括均为对称设置的两个柔性构件、两个连接杆和两个夹持件;所述柔性构件包括第一柔性杆和第二柔性杆,所述第一柔性杆的一端铰接于所述固定架,所述第一柔性杆设置有凹槽,所述凹槽设置有压力传感器,所述第二柔性杆的一端铰接于所述夹持件,所述第二柔性杆设置有凸起部,所述凸起部用于抵接所述压力传感器,所述连接杆的一端铰接于所述固定架,所述连接杆的另一端铰接于所述夹持件;所述驱动机构分别与两个所述柔性构件铰接,所述驱动机构通过驱动所述柔性构件运动,实现两个夹持件对物体进行自适应夹持或张开运动。该夹持器在夹持时产生的压力通过第二柔性杆的凸起部传递至传感器,与现有传感器安装在夹持件表面直接检测压力相比较,夹持件可以根据需要随时更换以适应不同种类物件的表面形状,无需重新设计传感方案,使夹持器适应性和灵活性更强。
