[0002] A vacuum suction cup is a common product that uses atmospheric pressure to fasten the suction cup to a flat surface. Vacuum suction cups are often used in the transportation of items with smooth surfaces, such as tiles, iron, glass, etc. Electric suction cups are a type of vacuum suction cup. Electric suction cups can reduce the manual vacuuming process, and can make the vacuum degree higher, the adsorption force greater, and easier to use.

This patent can make the suction cup adsorbed on an object by air suction by the pump body, and open the valve when the adsorption needs to be released, so as to realize one-button air intake.

[0004] The existing electric suction cup has the following problems. When the suction cup needs to pick up an object, the air pump is started and the air pump continues to suck air.

In addition, the air pump is not completely sealed. After the suction cup picks up the object, the air pump is turned off and the object is transported by the electric suction cup.

When the tiles / glass sucked up by the electric suction cup are transported, the internal air pressure is controlled within the set range through the monitoring of the air pressure sensor, so as to play the function of automatic pressure stabilization, avoiding external air from entering the multi-way pipe during use, causing the internal air pressure to change and causing the tiles / glass to fall off the electric suction cup.

[0017] In the air intake state, the air pump is controlled to stop and the electronically controlled valve is opened, and the external air enters the multi-way pipe through the electronically controlled valve to release the suction cup from the tile / glass, so that the electric suction cup can be detached from the tile / glass, achieving the effect of one-click air intake.

DETAILED DESCRIPTION

[0030] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0031] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0032] like Figure 1-10 As shown, an electric suction cup with an automatic voltage stabilization function includes a housing 1 and a suction cup 2 mounted on the housing 1. A multi-way pipeline, a controller 20, an electric-controlled valve 26 and an air pump 17 are arranged in the housing 1. The electric-controlled valve 26 and the air pump 17 are electrically connected to the controller 20. An air channel 11 connected to the adsorption surface is arranged on the suction cup 2. The multi-way pipeline has a first pipeline port 27, a second pipeline port 24 and a third pipeline port 25. The first pipeline port 27 is connected to the air channel 11, the second pipeline port 24 is connected to the air pump 17, and the third pipeline port 25 is connected to the electric-controlled valve 26.

[0033] The electric suction cup has a suction state and an intake (deflation) state. The suction state of the electric suction cup is used to suck the tile / glass, and the intake state of the electric suction cup is used to detach the sucked tile / glass. The specific contents are as follows:

[0034] When the electric suction cup is in the suction state, the suction surface of the suction cup 2 is attached to the object to be sucked, such as a tile / glass (the following content is expressed in terms of a tile / glass), the air pump 17 is controlled to start the air extraction, and the electric control valve 26 is closed. The air pump 17 gradually removes the air in the multi-way pipe and the air between the suction surface of the suction cup 2 and the tile / glass, so that a negative pressure is formed in the multi-way pipe, and the suction surface of the suction cup 2 sucks the tile / glass. After the tile / glass is sucked, the air pump 17 is controlled to be closed to stabilize the negative pressure. When the negative pressure is stabilized, the air pump 17 itself has a certain sealing property to prevent external air from entering the multi-way pipe from the air pump 17.

[0035] When the electric suction cup is in the air intake state, the tile / glass has been moved to the desired placement position. At this time, the electric suction cup needs to be separated from the tile / glass, the air pump 17 is controlled to stop, and the electric control valve 26 is opened. External air can enter the multi-way pipe from the electric control valve 26 to eliminate the negative pressure in the multi-way pipe and release the suction cup 2 from the tile / glass, so that the electric suction cup can be separated from the tile / glass to achieve a one-click air intake (deflation) effect.

[0036] The multi-channel pipeline has a fourth pipeline opening 23, and the fourth pipeline opening 23 is connected to the air pressure sensor 21. The air pressure sensor 21 is electrically connected to the controller 20, and the air pressure sensor 21 is used to detect the air pressure inside the multi-channel pipeline.

[0037] When the electric suction cup is used to carry tiles / glass, the air pressure sensor 21 monitors the air pressure changes inside the multi-way pipe and transmits a signal to the controller 20. When the air pressure sensor 21 detects that the air pressure inside the multi-way pipe drops to the lowest set value, the controller 20 controls the air pump 17 to stop pumping air. When the air pressure sensor 21 detects that the air pressure inside the multi-way pipe rises to the highest set value, the controller 20 controls the air pump 17 to start pumping air, so that when the electric suction cup starts to adsorb tiles / glass, the air pressure sensor 21 detects that the internal air pressure reaches the set value. value, the controller 20 will automatically control the air pump 17 to stop, and the control of the air pump 17 will be more precise and timely, avoiding the air pump 17 to stop too late and make the load operation time of the air pump 17 too long, or the air pump 17 to stop too early and the air pressure is not enough to suck the tiles / glass. When the tiles / glass sucked up by the electric suction cup are moved, the internal air pressure is controlled within the set range through the monitoring of the air pressure sensor 21 to play the role of automatic pressure stabilization, avoiding the external air from entering the multi-way pipe during use, causing the internal air pressure to change and make the tiles / glass fall off the electric suction cup.

[0038] For example, the maximum air pressure value is set to a and the minimum air pressure value is set to b in the controller 20, and the suction cup 2 of the electric suction cup is attached to the tile / glass to start the electric suction cup. At this time, the air pump 17 is started, and the electric control valve 26 is closed at the same time. The air pump 17 continues to pump out the air in the multi-way pipe and the air between the adsorption surface of the suction cup 2 and the tile / glass, so that the air pressure in the multi-way pipe gradually decreases to form a negative pressure. When the air pressure sensor 21 detects that the air pressure in the multi-way pipe drops to the air pressure value b, the controller 20 controls the air pump 17 to stop. At this time, the suction cup 2 sucks the tile / glass, and the worker can hold the electric suction cup to move the tile / glass. During the transportation process, due to the multi-way pipe, The connection points between the multi-channel pipes and the components, as well as the air pump 17 itself, may not be completely sealed. A small amount of air will slowly enter the multi-channel pipes from the external atmospheric environment and affect the internal air pressure of the multi-channel pipes. When the air pressure sensor 21 detects that the air pressure in the multi-channel pipes has risen to the air pressure value a, the controller 20 controls the air pump 17 to start exhausting air, so that the internal air pressure of the multi-channel pipes drops back to the air pressure value b. The above-mentioned operation of starting the air pump 17 when the air pressure rises and stopping the air pump 17 when the air pressure drops to the set value is repeated, so that the internal air pressure of the multi-channel pipes is automatically stabilized within an air pressure range, which can keep the suction cup 2 stably adsorbing the tiles / glass to prevent the tiles / glass from falling off.
