Magnetic control negative pressure enhanced adhesion device capable of imitating octopus sucker

Abstract

The invention request to protect a magnetic control negative pressure enhanced adhesion device capable of imitating an octopus sucker, belongs to the field of intelligent devices with a bionic structure, and includes structural design, a working principle and a manufacture way. The adhesion device is mainly divided into two parts, including an adhesion sucker and a regulation and control electromagnet. In the adhesion device disclosed by the invention, magnetic response materials are adopted to design and manufacture the adhesion sucker capable of imitating the octopus sucker, the regulation and control electromagnet is integrated above the adhesion sucker, a magnetic field is controlled to drive the inner cavity of the adhesion sucker to deform so as to generate negative pressure change similar to the octopus sucker, when the adhesion sucker adheres, adhesion force with a contact surface can be enhanced, when the adhesion sucker is separated, a peeling process is accelerated, and thepressure and the adhesion performance of the outer cushion of the adhesion sucker and the contact surface can be simultaneously regulated to guarantee a sealing effect of a negative pressure cavity. The magnetic control negative pressure enhanced adhesion device disclosed by the invention is conveniently manufactured and is low in cost, meanwhile, the adhesion performance is adjustable and controllable, and the magnetic control negative pressure enhanced adhesion device is in flexible contact, has high environmental suitability, and can be used for complex environment occasions which need to realize a quick adhesion / de-adhesion process, wherein the complex environment occasions include quick-transportation mechanical arm and foot-leg wall surface robots and the like.

Description

technical field [0001] The invention belongs to the field of bionic structure intelligent devices, and relates to a magnetically controlled negative pressure enhanced adhesion device imitating an octopus suction cup, which is mainly used in the functions of fast handling manipulators, wall robots with legs, etc., for handling, walking, and wall parking. Background technique [0002] In modern industry and infrastructure engineering, facilities and equipment will inevitably have problems such as friction damage, fatigue relaxation, aging and falling off, which will pose a serious threat to the safety of infrastructure and equipment, and affect the health of the facility and equipment structure in the slightest, and in severe cases. Cause damage or collapse, resulting in serious casualties and economic losses. Traditionally, inspections of facilities and equipment through manual surveys and fixed-point monitoring are time-consuming and labor-intensive, and in complex and speci...

AI Technical Summary

Problems solved by technology

For now, although the adhesion strength of some materials has reached or even surpassed that of gecko bristles, a large pressing force is required to achieve high adhesion; High cost, complicated mechanical control, and high requirements on system performance

The current adhesive sucker structure generally controls adhesion through force, and its use effect and device controllability are far from enough compared with biological organs

The sliding wall-climbing robot sealing skirt can better fill the gap between the suction cup and the wall surface, so that a vacuum environment is formed in the suction cup cavity, and it has certain adaptability to the rough wall surface. However, there is always friction between the suction cup and the wall surface during the movement of the robot. The sealing skirt is easy to wear, and the movement resistance is large; the negative pressure suction cup wall-climbing robot without a sealing mechanism has strong adaptability to the wall surface, no sliding friction, but the negative pressure is small, the required negative pressure generating device is bulky, and the volume of the suction cup is also large. Increase

In addition, the complex preparation process and high manufacturing cost are also obstacles to the large-scale promotion and use at present.
