Problems solved by technology

At present, there have been some good achievements in the field of flexible grasping devices at home and abroad, but there are still some problems: for example, the movement mode of the mechanical structure is single
The mechanical gripper mainly uses the finger part to perform the grabbing action. The finger is made of elastic material and has a weak load-bearing capacity. It will greatly increase the weight of the entire manipulator, which is inconvenient to use

Embodiment Construction

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings, and the aforementioned and other objects, features, aspects and advantages of the present invention will become more apparent, so that those skilled in the art can implement them with reference to the description. In the drawings, the shapes and dimensions may be exaggerated for clarity, and the same reference numerals will be used throughout to designate the same or like parts. In the following description, terms such as center, thickness, height, length, front, back, rear, left, right, top, bottom, upper, lower, etc. are based on the orientation or positional relationship shown in the drawings. In particular, "height" corresponds to the dimension from top to bottom, "width" corresponds to the dimension from left to right, and "depth" corresponds to the dimension from front to back. These relative terms are for convenience of description and are generally not ...

Abstract

The invention relates to a hand-like flexible grabbing device, which comprises a plurality of soft fingers, a driving mechanism and a rack. The soft fingers are distributed circularly and are of a cystic structure, and each soft finger is composed of a main body part and a fingertip part. The driving mechanism is used for inflating the soft fingers so that the soft fingers can bend to make a grabbing action. The rack is connected with the soft fingers, and is provided with interfaces for fixing the soft fingers and a cavity for placing the driving mechanism. The grabbing device of the invention is used for picking fruits and vegetables, does not damage the surfaces of fruits and vegetables in the picking process, and is suitable for picking fruits and vegetables of different quality and different shapes and sizes.

Description

technical field [0001] The invention relates to the field of picking manipulators, in particular to a human-like flexible pneumatic grabbing device. Background technique [0002] At present, the majority of fruit farmers often encounter many difficulties in fruit picking operations due to the diversity of fruits and the difference in the height of fruit trees. For fruits with husks, or with thicker skins and larger sizes, fruit farmers usually use large-scale machinery to pick them, and there are also many designs for individual fruit farmers to pick them. The stage undertakes or directly contacts the surface of the fruit with a rigid gripper to force grabbing. This picking method is easy to damage the structure of the fruit tree and the surface of the fruit. For fruits with soft surface, easy to break, and small size, there is no good solution at present. Most of the fruit growers use manual picking. Manual picking does ensure the integrity of the fruit and the structure o...
