Description

Technical Field

[0001] This utility model relates to the field of electric suction cups, and more particularly to an electric suction cup for adsorption and preventing detachment. Background Technology

[0002] Vacuum suction cups are common products that use atmospheric pressure to adhere and fix the suction cup to a flat surface. They are frequently used in transporting items with smooth surfaces, such as tiles, iron, and glass. Electric suction cups are a type of vacuum suction cup. Electric suction cups reduce the need for manual vacuuming and can achieve higher vacuum levels, stronger suction, and are easier to use.

[0003] For example, patent CN222860913U discloses an electric suction cup with automatic pressure stabilization function, including a housing and a suction cup mounted on the housing. The housing contains a multi-channel pipe, a controller, an electrically controlled valve, and an air pump. The electrically controlled valve and air pump are electrically connected to the controller. The suction cup has an air passage connecting to the suction surface. The multi-channel pipe has a first port, a second port, and a third port. The first port connects to the air passage, the second port connects to the air pump, and the third port connects to the electrically controlled valve. In suction mode, the air pump starts and the electrically controlled valve closes, allowing the suction surface of the suction cup to absorb air. In intake mode, the air pump stops and the electrically controlled valve opens, allowing external air to enter the multi-channel pipe to release the suction. The multi-channel pipe has a fourth port connected to a pressure sensor, which is electrically connected to the controller. The pressure sensor detects the air pressure inside the multi-channel pipe. This patent controls the air pump by detecting the air pressure between the suction cup and the suctioned item using a pressure sensor, stabilizing the air pressure between the suction cup and the suctioned item within a set range, thus maintaining the stability of the suction cup's suction of the item.

[0004] The existing electric suction cups have the following problems: The air pressure sensor detects the air pressure at the suction port connected to the air pump on the suction cup. In the case of a large suction cup, other parts of the suction cup bottom are far from the suction port, causing the air pressure at these locations to drop more slowly than at the suction port. When the air pressure sensor detects that the air pressure at the suction port has reached the pressure required to suction the item, the instantaneous air pressure at these locations may be higher than at the suction port, failing to meet the suction standard. At this point, the controller will stop the air pump because the air pressure at the suction port has reached the set value. If the operator then lifts the item using the electric suction cup, the suction cup at locations far from the suction port may detach from the item due to insufficient suction, potentially causing the item to fall and break. Utility Model Content

[0005] Based on the aforementioned air pressure sensor detecting the air pressure at the suction port connected to the air pump on the suction cup, in the case of a large suction cup, other locations on the bottom of the suction cup are far from the suction port. Therefore, during suction, the air pressure at these locations decreases more slowly than at the suction port. When the air pressure sensor detects that the air pressure at the suction port has reached the pressure required to adsorb the item, the instantaneous air pressure at locations on the bottom of the suction cup far from the suction port will be higher than at the suction port, failing to meet the standard for adsorbing the item. At this point, the controller will stop the air pump because the air pressure at the suction port has reached the set value. If the operator then lifts the item using the electric suction cup, the area far from the suction port may detach from the item due to insufficient suction, potentially causing the item to fall and break. This invention provides an electric suction cup with anti-detachment suction.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an electric suction cup for adsorption and anti-detachment, including a housing, a controller, a pressure sensor, an air pump, and a single suction cup mounted on the housing. The pressure sensor and the air pump are electrically connected to the controller. The suction cup is provided with a through-hole for air extraction, which is connected to the air pump. The suction cup is provided with a through-hole for air pressure detection, which is located away from the air extraction hole. The air pressure detection hole is connected to the pressure sensor. When the suction cup is adsorbed onto an object and the air pump is pumping air, the pressure sensor detects the air pressure at the air pressure detection hole.

[0007] A further preferred embodiment of this utility model is that the air extraction hole and the air pressure detection hole are located on the left and right sides of the suction cup, and the suction cup is racetrack-shaped, figure-eight-shaped, or elliptical.

[0008] A further preferred technical solution of this utility model is as follows: it also includes an electrically controlled valve, and a multi-channel pipe is provided between the air pump and the air extraction hole. The electrically controlled valve, the air pump and the air extraction hole are respectively connected to one pipe opening of the multi-channel pipe. In the air intake state, the air pump stops and the electrically controlled valve opens to allow external air to enter the air extraction hole to release the suction cup's adsorption.

[0009] A further preferred technical solution of this utility model is as follows: a one-way valve is provided between the air pump and the pipe opening of the multi-way pipe. The one-way valve restricts the gas to flow only from the pipe opening of the multi-way pipe to the air pump. Each pipe opening of the multi-way pipe is connected to the air pump, the electrically controlled valve and the air extraction port through a flexible hose. The one-way valve is installed on the flexible hose between the air pump and the pipe opening of the multi-way pipe.

[0010] A further preferred embodiment of this utility model is as follows: the air pressure sensor and the air pump are respectively disposed on the left and right sides of the housing. The housing includes a handle, a left housing and a right housing. The left housing and the right housing are respectively fixed on the left and right sides of the handle. The left housing and the right housing are connected to the left and right sides of the suction cup. The air extraction hole and the air pressure detection hole are respectively located below the left housing and the right housing.

[0011] A further preferred technical solution of this utility model is as follows: an elastic rubber sleeve is provided between the left and right shells and the top of the suction cup. The left and right shells are provided with a first through hole on both sides. The connecting bolt passes through the first through hole and the elastic rubber sleeve and is threadedly connected to the top of the suction cup.

[0012] A further preferred embodiment of this utility model is as follows: the air pressure sensor is installed inside the grip and located at the top of the left housing. A detection air tube is connected to the air pressure sensor, and the detection air tube passes through the left housing and connects to the air pressure detection hole.

[0013] A further preferred technical solution of this utility model is as follows: the suction cup, the left shell, the right shell and the handle form a ring for the fingers to insert when the hand is gripping the handle, and a control switch is provided on the inner side of the handle opposite to the suction cup below.

[0014] A further preferred embodiment of this utility model is as follows: the housing is provided with a mounting part and a control panel, the control panel is provided with control buttons and a display screen that are electrically connected to the controller, and the mounting part is used for the detachable installation of the battery pack.

[0015] Compared with the prior art, the advantage of this utility model is that the suction cup is provided with a through-hole for air extraction and a pressure detection hole. The air extraction hole is connected to an air pump for air extraction, and the pressure detection hole is connected to a pressure sensor for detecting changes in air pressure at the pressure detection hole and transmitting the signal to the controller. When the pressure sensor detects that the air pressure at the pressure detection hole drops to the minimum set value, the controller controls the air pump to stop extracting air. When the pressure sensor detects that the air pressure at the pressure detection hole rises to the maximum set value, the controller controls the air pump to start extracting air. This allows the electric suction cup to control the internal air pressure within the set range through the monitoring of the pressure sensor when moving the object being sucked up, thereby achieving an automatic pressure stabilization function. This prevents external air from entering between the suction cup and the object during use, causing changes in internal air pressure that could cause the object to fall off the electric suction cup.

[0016] By separating the air pressure detection port and the suction port and placing them at a considerable distance, the air pressure sensor detects the area where the air pressure drops more slowly, away from the suction port, during air pumping. This means that the air pressure at the sensor's detection point will be higher than the air pressure at the suction port during suction. The air pump is controlled by detecting this pressure. When the air pressure at the detection port drops to the minimum set value, it indicates that the air pressure between the suction cup and the object being suctioned is generally below the minimum set value, and the controller stops the air pump. This structure prevents the air pump from stopping when the suction port reaches the set pressure value while other locations haven't, thus preventing areas below the suction cup that haven't reached the set pressure value from detaching from the object when the electric suction cup is lifted.

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0027] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0028] Figures 1-7 As shown, the electric suction cup for adsorption and anti-detachment includes a housing 1, a controller 13, an air pressure sensor 16, an air pump 14, an electric control valve 15, and a single suction cup 2 mounted on the housing 1. The air pressure sensor 16 and the air pump 14 are electrically connected to the controller 13. The air pump 14 is an electric air pump. The suction cup 2 is provided with an air extraction hole 21, which runs through the upper and lower sides of the suction cup 2. The air extraction hole 21 is connected to the air pump 14 for extracting air when the air pump 14 is working. The electric suction cup is placed on the surface of the object to be adsorbed, and the air pump 14 is started. The air pump 14 extracts the air between the suction cup 2 and the object to form a negative pressure between the suction cup 2 and the object, thereby adsorbing the object through the suction cup 2.

[0029] Figure 5 , Figure 6 As shown, a multi-port pipe 18 is provided between the air pump 14 and the air extraction port 21, and the electric control valve 15, the air pump 14 and the air extraction port 21 are respectively connected to one port of the multi-port pipe 18.

[0030] The electric suction cup has two states: suction and intake (release). The suction state is used to pick up the object to be adsorbed (e.g., tile / glass), and the intake state is used to detach from the adsorbed object. The electric control valve 15 is electrically connected to the controller 16.

[0031] When the electric suction cup is in suction mode, the suction surface of suction cup 2 is attached to the object to be suctioned. The air pump 14 is activated to draw air, and the electronic valve 15 is closed. The air pump 14 gradually removes air from the multi-channel pipe 18 and the space between the suction surface of suction cup 2 and the object, creating a negative pressure between them. The suction surface of suction cup 2 then holds the object in place. After the object is held in place, the air pump 14 is turned off to stabilize the negative pressure. During this stable negative pressure period, the air pump 14 has a certain degree of sealing to prevent external air from entering the multi-channel pipe 18.

[0032] When the electric suction cup is in the air intake state, the object being suctioned has been moved to the desired position. At this time, it is necessary to detach the electric suction cup from the object, control the air pump 14 to stop, and open the electric control valve 15. External air enters the space between the suction cup 2 suction surface and the object through the electric control valve 15, the multi-channel pipe 18 and the air extraction hole 21, to eliminate the suction force generated by the negative pressure, thereby detaching the electric suction cup from the object and achieving a one-button air intake (air release) effect.

[0033] Preferably, the multi-port pipe 18 is a three-way pipe, and each port of the three-way pipe is connected to the air pump 14, the electric control valve 15 and the air extraction port 21 through the hose 19 respectively.

[0034] A one-way valve 20 is provided between the air pump 14 and the inlet of the multi-port pipe 18. The one-way valve 20 restricts gas flow to the air pump 14 only from the inlet of the multi-port pipe 18. The one-way valve 20 is installed on the flexible hose 19 between the air pump 14 and the inlet of the multi-port pipe 18. The one-way valve 20 improves the airtightness between the air pump 14 inlet and the multi-port pipe 18 inlet.

[0035] Preferably, the electrically controlled valve 15 can be a solenoid valve, or the electrically controlled valve 15 includes an electrically operated gripper. By controlling the electrically operated gripper to clamp or release the hose 19, the airflow or closure of the hose 19 corresponding to the electrically controlled valve 15 in the multi-port pipe 18 is controlled. Preferably, the electrically controlled valve 15 is a normally closed solenoid valve.

[0036] Figure 4 , Figure 7 As shown, a pressure detection hole 22 is provided on the suction cup 2 at a position away from the air extraction hole 21. The pressure detection hole 22 extends through the upper and lower sides of the suction cup 2. The pressure detection hole 22 is connected to the pressure sensor 16. When the suction cup 2 is attached to an object and the air pump 14 is pumping air, the pressure sensor 16 detects the pressure change at the pressure detection hole 22 and transmits the signal to the controller 13. The controller 13 controls the working state of the air pump 14 according to the pressure change at the pressure detection hole 22.

[0037] During the process of suction cup 2 adsorbing an object and moving the adsorbed object by the electric suction cup, the air pressure sensor 16 detects the air pressure change between suction cup 2 and the object at the air pressure detection hole 22 in real time and transmits the signal to the controller 13. When the air pressure sensor 16 detects that the air pressure at the air pressure detection hole 22 drops to the minimum set value due to the air pump 14, the controller 13 controls the air pump 14 to stop pumping. When the air pressure sensor 16 detects that the air pressure at the air pressure detection hole 22 rises to the maximum set value, the controller 13 controls the air pump 14 to start pumping. This allows the electric suction cup to control the internal air pressure within the set range through the monitoring of the air pressure sensor 16 when adsorbing an object, thereby achieving an automatic pressure stabilization function. This prevents external air from entering between suction cup 2 and the object during use, causing changes in internal air pressure that could cause the object to fall off the electric suction cup.

[0038] For example, the controller 13 sets the maximum air pressure value to 'a' and the minimum air pressure value to 'b'. The electric suction cup 2 is attached to the surface of the object to be suctioned, and the electric suction cup is activated. At this time, the air pump 14 starts, and the electronically controlled valve 15 closes. The air pump 14 continuously draws air from the multi-channel pipe 18 and the air between the suction cup 2's suction surface and the object to be suctioned, causing the internal air pressure to gradually decrease and form a negative pressure. When the air pressure sensor 16 detects that the air pressure at the air pressure detection port 22 has dropped to air pressure value 'b', the controller 13 controls the air pump 14 to stop. At this time, the suction cup 2 will hold the object to be suctioned, and the worker can hold the electric suction cup to move the suctioned object. During the moving process, due to… The connections between the multi-channel pipe 18 and various components, as well as the air pump 14 itself, may not be completely sealed. A small amount of air may slowly enter the space between the suction cup 2's adsorption surface and the object from the external atmosphere. When the air pressure sensor 16 detects that the air pressure at the air pressure detection hole 22 has risen to air pressure value a, the controller 13 controls the air pump 14 to start pumping air, causing the air pressure between the suction cup 2's adsorption surface and the object to drop back to air pressure value b. This process repeats, where the air pump 14 starts when the air pressure rises and stops when the air pressure drops to the set value. This ensures that the air pressure between the suction cup 2's adsorption surface and the object is automatically stabilized within a certain air pressure range. This air pressure range can keep the suction cup 2 stably adsorbing the object and prevent the object from falling off.

[0039] In this patent, the air pressure detection hole 22 and the suction hole 21 are set separately and far apart, so that when the air pump 14 is pumping air, the air pressure sensor 16 detects the position where the air pressure drops more slowly away from the suction hole 21. That is to say, during the pumping process, the air pressure at the detection point of the air pressure sensor 16 will be higher than the air pressure at the suction hole 21 by a certain value. The air pump 14 is controlled by detecting the air pressure at this position. When the air pressure at the air pressure detection hole 22 drops to the minimum set value, it means that the air pressure at various points between the suction cup 2 and the object being suctioned will not be higher than the minimum set value. Only then will the controller 13 control the air pump 14 to stop pumping air. This structure can prevent the controller 13 from stopping the air pump 14 when the suction hole 21 reaches the set air pressure value while other positions have not reached the set air pressure value, thus preventing the position below the suction cup 2 that has not reached the set air pressure value from directly separating from the object when the electric suction cup is lifted.

[0040] Preferably, the suction port 21 and the air pressure detection port 22 are located on the left and right sides of the suction cup 2. When the air pump 14 evacuates air from the space between the suction cup 2 and the object through the suction port 21, the air pressure sensor 16 detects the air pressure at the air pressure detection port 22. When the air pressure at the left air pressure detection port 22, which is away from the right suction port 21, reaches the air pressure set value, the right suction port 21 has already fallen below the air pressure set value. The controller 13 controls the air pump 14 to stop. After the air pump 14 stops, the air pressure on the left and right sides of the space between the suction cup 2 and the object balances and reaches the same value.

[0041] Preferably, the suction cup 2 is racetrack-shaped, figure-eight-shaped, or elliptical.

[0042] Figure 1 , Figure 2 As shown, in order to facilitate connection with the air extraction port 21 and the air pressure detection port 22, the air pressure sensor 16 and the air pump 14 are respectively set on the left and right sides of the housing 1. The housing 1 includes a handle 3, a left housing 5 and a right housing 4. The left housing 5 and the right housing 4 are respectively fixed on the left and right sides of the handle 3. The left housing 5 and the right housing 4 are connected to the left and right sides of the suction cup 2. The air extraction port 21 and the air pressure detection port 22 are respectively located below the left housing 5 and the right housing 4.

[0043] The air pressure sensor 16 is installed inside the grip 3 and located above the left housing 5. A detection air tube 17 is connected to the air pressure sensor 16. The detection air tube 17 passes through the left housing 5 and connects to the air pressure detection port 22. The detection air tube 17 is a flexible tube 19.

[0044] The air pump 14 is located inside the right housing 4.

[0045] The suction cup 2, left housing 5, right housing 4, and grip 3 form a ring for the fingers to insert when the hand grips the grip 3. A control switch 10 is provided on the inner side of the grip 3 opposite to the suction cup 2 below. The control switch 10 is located below the grip 3 for easy activation when the hand grips the grip.

[0046] Figure 3 As shown, elastic rubber sleeves 8 are supported between the left housing 5 and the right housing 4 and the top of the suction cup 2. The left housing 5 and the right housing 4 are provided with through first through holes 11 on both sides. The connecting bolt passes through the first through holes 11 and the elastic rubber sleeves 8 and is threaded to the top of the suction cup 2. The elastic rubber sleeves 8 support the housing 1 and the suction cup 2, which can effectively improve the feel when pressing down or lowering the suction cup 2.

[0047] Both the left housing 5 and the right housing 4 have an annular groove at their lower ends. The upper end of the elastic rubber sleeve 8 has an annular protrusion 12 that protrudes laterally inward. The annular protrusion 12 is inserted into the groove to connect the elastic rubber sleeve 8 to the left housing 5 and the right housing 4, so as to prevent the elastic rubber sleeve 8 from shifting relative to each other.

[0048] The housing 1 is provided with a mounting part 9 and a control panel. The control panel is provided with a control button 6 and a display screen 7 that are electrically connected to the controller 13. The mounting part 9 is used for the detachable installation of the battery pack.

[0049] Preferably, the controller 13 is a control circuit board.

[0050] The housing 1 has a gap that connects to the external atmosphere, and the air pump 14 exhausts gas or supplies external gas into the electrically controlled valve 15.
