Vacuum suction cup working principle
The working principle of the straight vacuum chuck is shown in the figure. First, the vacuum chuck is connected to the vacuum device through the nozzle, and then contacted with the object to be lifted, such as glass, paper, etc., and the vacuum device is started to be sucked, so that a negative air pressure is generated in the suction cup, thereby sucking the object to be lifted, and then starting to move. Lifting things. When the object to be lifted is transported to the destination, it is smoothly inflated into the vacuum chuck, and the vacuum suction cup is changed from the negative air pressure to the zero air pressure or a slightly positive air pressure, and the vacuum suction cup is separated from the object to be lifted, thereby completing the lifting and transporting the heavy object. Task.
