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

Abstract

The invention discloses a vibration and suction mechanism with adjustable eccentric wheels. The vibration and suction mechanism comprises a vibration unit, a driving unit and a base; the vibration unit comprises four levers, four suckers, four guiding columns and a plurality of pins; and the driving unit consists of two motors, a worm, a piston, eccentric wheels and a guiding frame. The vibrationand suction mechanism realizes vibration and suction of the four suckers by one motor, while the other motor can change vibration amplitude by changing the eccentric wheels. By matched use of the worm and the piston, the vibration and suction mechanism can realize fine adjustment of the offset of the eccentric wheels, thus improving the precision and controllability of vibration amplitude changing.

Description

technical field [0001] The invention relates to a mechanism for vibration adsorption using a sucker, more particularly, a vibration adsorption mechanism with an adjustable eccentric wheel that does not interfere with each other in 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 wi...
