Embodiment

[0030] see Figure 1 to Figure 5 , the liquid-tight vacuum chuck based on the present embodiment includes a suction cup body 100, the suction surface of the suction cup body 100 is provided with an inner sealing ring 101 and an outer sealing ring 102, and the suction cup body 100 is provided with a liquid storage chamber 103 and a vacuum chamber 104. The top of the body 100 is provided with a quick connector threaded hole 105 connected to the vacuum chamber 104 and a liquid external nozzle 106 connected to the liquid storage chamber 103 .

[0031] The liquid storage chamber 103 is an annular cavity, and an annular gap is formed between the inner sealing ring 101 and the outer sealing ring 102, and a circle of hole array 107 is arranged between the gap and the liquid storage chamber 103 for sealing the liquid storage chamber The liquid in 103 flows into the gap to improve the adsorption force.

[0032] The suction cup body 100 of this embodiment is manufactured by 3D printing,...

Abstract

The invention relates to a vacuum suction cup based on liquid sealing and an adsorption method thereof, belonging to the technical field of vacuum suction cups. Including the suction cup body, the suction surface of the suction cup body is provided with at least two layers of sealing rings, and there is a gap between adjacent sealing rings; the suction cup body is provided with a liquid storage chamber, and a device connecting the liquid storage chamber to the adjacent sealing rings Gap channel. By setting up multi-layer sealing rings, absorbing them, passing liquid between adjacent sealing rings, using the fluidity and viscosity of the liquid to fill the small gaps that cannot be completely covered by the sealing rings, the sealing performance of the suction cup is greatly improved. . Can greatly improve the adsorption capacity and adsorption stability, less energy consumption. Moreover, the overall installation of the suction cup is convenient and occupies a small volume.

Description

technical field [0001] The invention relates to the technical field of vacuum chucks, in particular to a liquid-tight vacuum chuck and an adsorption method thereof. Background technique [0002] Vacuum suction cups are widely used in the field of industrial production and manufacturing, and play an irreplaceable role in human production and manufacturing activities. The ability to be adsorbed on the surface of different materials makes it a widely used end effector for industrial robots, and it is applied to the operation of handling moving parts, items or food on the production line. At the same time, it is also used in wall-climbing robots to climb walls that some people cannot safely reach to perform tasks such as detection and cleaning. [0003] The Chinese patent document whose publication number is CN108584666A discloses a vacuum chuck for industrial automation equipment. The Chinese patent document whose publication number is CN207454515U discloses a vacuum chuck. T...
