Technical Problem

[0005]为此，本发明所要解决的技术问题在于克服现有技术中柔性抓手装置在抓取形状不规则物体时，存在对物体造成破坏或易掉落的风险，抓取稳定性不高

Benefits of technology

[0023]本发明所述的柔性抓手装置包括基座、至少两组柔性手臂、控制件、锁定件以及驱动件，所述基座包括底座和背板，所述柔性手臂滑动设置在所述背板两侧；所述控制件控制所述柔性手臂弯曲；所述柔性手臂弯曲后，所述锁定件连接两组所述柔性手臂；所述驱动件与所述底座连接，所述驱动件驱动所述柔性手臂移动；其中，所述驱动件驱动至少两组所述柔性手臂移动至物体的两侧，所述控制件控制所述柔性手臂弯曲，直至所述锁定件连接所述柔性手臂；所述驱动件驱动所述柔性手臂拉回物体，直至物体的一侧抵压所述背板。所述的柔性抓手装置在使用时，柔性手臂能够根据物体的形状适配弯曲变形，至少两件柔性手臂弯曲包裹在物体的周侧，背板抵压在物体的另一侧，从而使物体被牢固抓抱，柔性手臂、背板的配合抓抱，在满足形状不规则物体抓抱的基础上，增大了柔性抓手装置与物体的抓取接触面积，减弱了物体某一位置处受到的最大抓握力量，降低了物体被破坏的风险；且周侧抓抱避免了物体在搬运时容易掉落的风险，提高了柔性抓手装置的稳定性与适配性。

Abstract

The application discloses a flexible gripper device, and relates to the technical field of robots, which comprises a base, at least two groups of flexible arms, a control member, a locking member and a driving member, the base comprises a base plate and a back plate, the flexible arms are slidably arranged on the two sides of the back plate, the control member controls the bending of the flexible arms, the locking member is connected to the two groups of flexible arms after the bending of the flexible arms, the driving member is connected to the base plate, and the driving member drives the movement of the flexible arms, wherein the driving member drives the movement of the at least two groups of flexible arms to the two sides of an object, the control member controls the bending of the flexible arms until the locking member is connected to the flexible arms, and the driving member drives the flexible arms to pull back the object until one side of the object is pressed against the back plate. The flexible gripper device can grasp irregular-shaped objects, and has the effects of reducing the risk of damage to the object, improving the stability and adaptability of grasping.
