Negative-pressure blocking miniature soft gripper

Abstract

The invention discloses a negative-pressure blocking miniature soft gripper which comprises a connecting piece with one end connected with a transmission device and a flexible clamping piece connectedto the other end of the connecting piece; and a clamping opening is formed in the flexible clamping piece, the clamping opening is in a U shape, an inner cavity surrounding the clamping opening is formed in the flexible clamping piece, outer cavities are symmetrically formed in the two sides of the inner cavity, the outer cavities are filled with shaping particles, and the outer cavities are connected with air pressure adjusting equipment through air pipes. The negative-pressure blocking miniature soft gripper is good in part protectiveness, and due to the fact that the negative-pressure blocking miniature soft gripper is made of a flexible material, indentations cannot be left on the machining face of a part; the grabbing precision is high, opening and closing of the clamping opening inthe flexible clamping piece are a gradual process, the operable space is large in the grabbing process, the position of the part can be better determined, and the possibility of misoperation is reduced; and the clamping effect is good, the rigidity of the clamping opening in the flexible clamping piece is gradually increased in the closing process, and reliable clamping force is provided while constraint is provided for the part.

Description

technical field [0001] The invention relates to the technical field of mechanical grippers, in particular to a negative-pressure blocking miniature soft gripper. Background technique [0002] With the development of society, grippers are not only used in traditional industrial fields, but also widely used in food, medical, robotics and other fields. These fields have relatively high requirements for the accuracy of clamping parts. The vast majority of existing manufacturers use manual loading and unloading of micro-sized parts, which is not only time-consuming and labor-intensive, but also prone to errors in accuracy. Obviously, the use of manual labor cannot meet the increasing requirements of the yield rate. At the same time, when the traditional soft gripper is gripping an object, its rigidity is small, and it is easy to cause the object to fall. Therefore, how to effectively harden itself and achieve independent control of stiffness and bending angle is an important dir...

Most of the existing manufacturers use manual loading and unloading of micro-sized parts, which is not only time-consuming and labor-intensive, but also prone to errors in accuracy. Using manual labor obviously cannot meet the increasing requirements of the yield rate

At the same time, the traditional soft grippers are less rigid when gripping objects, which can easily cause objects to fall
