The control means is electrically connected to the release valve 300 and the receiving means 200, respectively, and is configured to control the release valve 300 to open to let air into the chamber 23 to release the grip, in response to a wireless release signal from the receiving means 200.

The receiving device 200 needs to be used with a transmitting device. The transmitting device is configured to transmit a wireless release signal to the receiving device 200. When the clamping needs to be released, the user operates the transmitting device to remotely or remotely transmit a wireless release signal to the receiving device 200, and after the receiving device 200 receives the wireless release signal, the control device controls the release valve 300 to be opened according to the wireless release signal from the receiving device 200, so that air enters the chamber 23 through the base 11 and the negative pressure state of the chamber 23 is released, and the vacuum chuck clamp 100 is released.

Preferably, the receiving device 200 is configured as a radio frequency receiver and the transmitting device is configured as a radio frequency transmitter, for example for wireless communication via bluetooth, Wifi network, 4G or 5G cellular network, etc. The wireless communication mode is stable, reliable, simple and easy to operate.

When the vacuum chuck apparatus 100 is operated, the air pressure sensor 400 detects the air pressure in the chamber 23, and the control device controls the display device 500 to display the air pressure value, so that the user can know the pressure change in the chamber 23. Preferably, the display device 500 is a liquid crystal display screen, and may be disposed on the top surface of the pump chamber 31 for convenient observation by a user.

As shown in fig. 4, the vacuum chuck jig 100 further includes a switching device 600, and the switching device 600 is electrically connected to the control device. The switching device 600 is used for switching the unit of the air pressure value displayed by the display device 500. Alternatively, the switching device 600 may be a button, and the displayed air pressure changes by one unit every time the user presses the button, and the air pressure value number also changes with the unit change.

Optionally, the preset air pressure unit includes, but is not limited to, standard atmospheric pressure, bar (bar), pascal (Pa), pound force Per Square Inch (PSI), and the like. Preferably, the switching device 600 is disposed near the display device 500 on the top surface of the pump chamber 31 for convenient use by the user.

In some cases, users are often more concerned about the maximum weight of the object that can be held under this pressure. It will be appreciated by those skilled in the art that there is a pressure differential between the air pressure (absolute pressure) in the chamber 23 and the ambient air pressure (absolute pressure). This pressure difference is multiplied by the contact area of the chamber 23 with the object, and the resulting value is the maximum weight of the object that can be held under this pressure of the chamber 23. Preferably, the control means calculates the maximum weight that can be held under the air pressure (the external air pressure may be calculated as 1 standard atmosphere pressure in general) based on the air pressure of the chamber 23 detected by the air pressure sensor 400, and controls the display means 500 to display the maximum weight. It will be appreciated that the switching device 600 may also be used to switch the unit of maximum weight, similar to the unit of switching the air pressure value. Alternatively, the switching device 600 may be a button, and the displayed maximum weight value number changes with the unit change every time the user presses the button. Alternatively, the unit of the maximum weight may be preset in the control device, and the switching device 600 is configured to perform cyclic switching in the preset unit. Optionally, the predetermined maximum weight units include, but are not limited to, grams (g), kilograms (kg), tons (T), ounces (oz), pounds (lb), and the like.

As described above, the maximum weight that can be held by the vacuum chuck jig 100 under the atmospheric pressure can be calculated based on the atmospheric pressure value detected by the atmospheric pressure sensor 400, and when the maximum weight that can be held by the vacuum chuck jig 100 under the atmospheric pressure in the chamber 23 reaches a desired value, the control device controls the air-extracting device 32 to stop extracting air.

It will be appreciated that there may be a leakage flow at the contact surface 22 of the vacuum chuck 100 with the object and that after the suction device 32 stops, the pressure within the chamber 23 may rise back, resulting in a decrease in the maximum weight that the vacuum chuck 100 can hold. To prevent the object from falling off the clamp, the control device controls the suction device 32 to suck air to increase the clamping force when the maximum weight that can be clamped by the vacuum chuck clamp 100 under the air pressure in the chamber 23 is less than a desired value.
