Working principle of vacuum cups

Working principle of vacuum cups:

The working principle of the flat vacuum suction cup is shown in Figure 1. First, connect the vacuum suction cup with the vacuum equipment (such as vacuum generator, not shown in the figure) through the connecting pipe, then contact with the object to be lifted, such as glass and paper, start the vacuum equipment suction, so that negative air pressure will be generated in the suction cup, so that the object to be lifted can be firmly absorbed, and then the object to be lifted can be moved. When the object to be lifted is transported to the destination, it is smoothly inflated into the vacuum suction cup, which makes the vacuum suction disk change from negative pressure to zero or slightly positive pressure. The vacuum suction cup will be separated from the object to be lifted, thus completing the task of lifting and conveying the heavy objects.
