Abstract

A flexible pneumatic mechanical arm achieving multifunctional gripping comprises a drive mechanism and a gripping device. The drive mechanism is connected with the gripping device. The gripping device comprises a first flexible finger, a second flexible finger, a third flexible finger and a fourth flexible finger. When the gripping device grips an object, the first flexible finger, the second flexible finger, the third flexible finger and the fourth flexible finger are in a cross-shaped state or in a rectangular state to conduct gripping. The cross-shaped state means that each flexible finger is located at the corresponding end of a cross. The rectangular state means that the flexible fingers are located on the four corners of a rectangle correspondingly. The drive mechanism can drive the gripping device to switch from the cross-shaped state to the rectangular state or from the rectangular state to the cross-shaped state. The flexible pneumatic mechanical arm achieving multifunctional gripping can achieve rapid switch between the cross-shaped gripping state and the rectangular gripping state and is suitable for multiple types of objects, good in gripping stability, accurate in gripping and high in efficiency.

Description

technical field [0001] The invention relates to a manipulator, in particular to a flexible pneumatic manipulator with multi-functional grasping. Background technique [0002] With the continuous development of robot technology, more and more manipulators are used in industrial automation production. Traditional industrial manipulators are generally rigid manipulators, which have good control accuracy and operability, but they are generally large in size, require a large work space, and are not easy to grab some relatively small objects. It is not suitable to grab and carry irregularly shaped, fragile and vulnerable objects. However, in the food industry, packaging industry, communication industry and other industrial automation production, it is often necessary to grasp and carry such objects. Rigid manipulators cannot complete these tasks, and manual completion of this work is inefficient, with low precision and large errors. Therefore, designing new objects that are flex...
