Amplitude-changing sine vibration and suction mechanism

Abstract

The invention discloses an amplitude-changing sine vibration and suction mechanism, consisting of a vibration unit, a varying-amplitude unit and a base; the vibration unit comprises four suckers, four guiding columns, two levers, a motor, two guiding frames and two eccentric wheels; and the varying-amplitude unit comprises a motor, a driving gear, a driven gear, a screw rod, a polished rod, two sliding blocks and a plurality of bearing seats and bearings. The vibration and suction mechanism realizes the vibration and suction of the suckers by one motor, while the other motor can change vibration amplitude. The adoption of the screw rod, the polished rod and the levers can guarantee the relative independence of the vibration of the suckers and the change of the vibration amplitude without mutual interference.

Description

technical field [0001] The invention relates to a mechanism for vibration adsorption using a sucker, more particularly, a vibration adsorption mechanism with non-interference between vibration and amplitude. Background technique [0002] In a broad sense, vibration refers to the process in which the parameters (such as displacement and voltage) that describe the state of the system change alternately up and down their reference values. In a narrow sense, it refers to mechanical vibration, that is, vibration in a mechanical system. Assuming that the air pressure in the sucker cavity is equal to the external atmospheric pressure, the state is the equilibrium state. When the skirt of the sucker is in good contact with the wall in the natural state, the height is the equilibrium height, and the height of the sucker is the equilibrium height under the action of external force The phenomenon that the wall is adsorbed by vibrating with a certain amplitude as the center is called ...

Problems solved by technology

This negative pressure value can ensure that the suction cup can generate sufficient adsorption force, but the disadvantage is that the vacuum generating device needs to drag a long air pipe, which makes the whole robot body bulky, which is not conducive to the miniaturization of the robot

Passive adsorption relies on suction cup expansion to generate negative pressure. It does not require vacuum generators and air pipes, and it is easy to realize the miniaturization of the robot body. However, the disadvantage is that the negative pressure generated is small. Decreased, can not continue to adsorb on the wall
