Publication number: 20210347063Abstract: The present invention provides a chain plate flexible finger including a chain plate framework, a pneumatic elastic bellows artificial muscle, and a plastic annular frame. The axial expansion of the elastic bellows artificial muscle is restricted by the chain plate framework to overcome the elastic force of a tension spring to bend, to generate conformal contact between one or more chain plates and an object to be gripped and generate a contact force for a gripping state. With the control of a high-speed on-off valve, the air pressure in an inner cavity of the elastic bellows artificial muscle is accurately controlled to vertically or horizontally grip a cylindrical object, a cuboid object, a spherical object or an ellipsoid object. The flexible finger has adequate flexible adaptability and a simple structure, and is reliable to use, and adapts to differently shaped objects to be gripped and vertically and transversely placed objects.Type: ApplicationFiled: September 4, 2019Publication date: November 11, 2021Inventors: Jun ZHANG, Qiang WANG, Dingfeng XU, Zhengning TANG, Bing LV
