Working principle of vacuum sucker (vacuum sucker adsorption principle)
The vacuum sucker mainly uses the principle of vacuum technology, which is to use vacuum negative pressure to “adsorb” objects to achieve the purpose of clamping items, and carry out the operation of handling, machine tools, etc.

When the vent and the vacuum device are connected to each other, once the vacuum device is opened and started, the vent starts to vent, and the air inside the sucker is sucked away, resulting in a vacuum state with a pressure of P2. The value of the air pressure inside the sucker will be lower than the atmospheric pressure P1 outside the sucker, that is, P2
