Abstract

The invention discloses a manufacturing method of a multi-cavity type soft gripper. The manufacturing method comprises the steps that firstly, a structure of the multi-cavity type soft gripper is designed, and materials of the multi-cavity type soft gripper are determined; a structure corresponding to a pouring mold is determined according to the structure, and a mold entity is obtained through a 3D printing technology; a mold core material with a melting point different from that of a high polymer material of the multi-cavity type soft gripper is selected, and a mold core mold is obtained through the 3D printing technology; and the mold is placed well, a high polymer material solution is poured into the mold, the soft gripper is taken out, and finally the mold core is molten to form an internal cavity. According to the manufacturing method of the soft gripper, the overall structure is compact, the cost is low, and the requirements for materials and manufacturing tools are not high. The soft gripper is stable in performance, capable of continuously working, high in adaptability and not prone to damage. The limitation of traditional application adhesion and an overall 3D printing method is broken through, and besides a pneumatic method, a function of the gripper can be achieved in a hydraulic mode. The method can be more applied to manufacturing processes of various soft structures in future.

Description

technical field [0001] The invention relates to the technical field of soft robots, in particular to the design of a multi-cavity soft gripper based on integral perfusion molding. Background technique [0002] In recent years, with the continuous development of robot technology and the emergence of artificial intelligence, robots have been applied to all aspects of life. Although the traditional rigid robot has a large carrying capacity, it can no longer meet the needs of production and life due to shortcomings such as poor adaptability and single operating object when faced with complex operating environments and complex operating objects. Since scientists began to pay attention to the research of soft organisms in nature, soft robots have gradually entered the public's field of vision. They can produce corresponding deformations according to the external environment, and the main part and executive part of soft robots are composed of polymer elastic flexible materials. St...
