Description

Technical Field

[0001] This application belongs to the field of handling tools technology, specifically relating to a suction cup device. Background Technology

[0002] Suction cups are core tools in industrial material handling, logistics warehousing, and home repair. Their design is based on vacuum adsorption technology. The suction cup forms a sealed space with the object's surface, creating negative pressure by expelling internal air, thus enabling non-destructive gripping and handling. A suction cup consists of a suction cup and a handle connected to it. Operators can hold the handle to move objects.

[0003] In related technologies, the handle and suction cup are connected and fixed by screws or other connectors. When the suction cup is working, all the pulling force is applied to the connector between the handle and the suction cup. When the connector becomes loose or breaks, the suction cup can easily separate from the handle, causing the object to fall and potentially damaging it or injuring the operator. Utility Model Content

[0004] The purpose of this application is to provide a suction cup device that can solve the problem in related technologies where the handle and suction cup of the suction cup device easily separate, causing objects to fall.

[0005] This application embodiment provides a suction cup, the suction cup comprising:

[0006] A suction cup, wherein the suction cup is provided with an adsorption groove, the adsorption groove being used to create a negative pressure and adsorb objects;

[0007] The handle, at least a portion of which is integrally formed with the suction cup.

[0008] In this embodiment, at least a portion of the handle is integrally formed with the suction cup. This makes the connection between the handle and the suction cup tighter and more secure, eliminating the possibility of separation due to improper installation, loose connection, or damage to the connector. This effectively improves the connection strength between the handle and the suction cup. When moving objects, even under significant external force, the handle and suction cup are less likely to break or separate, thus ensuring the safety and stability of object handling.

[0038] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0039] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0040] The suction cup provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0041] refer to Figures 1-15 The present application provides a suction cup device, such as... Figure 1 As shown, it may include a suction cup 100, which may be provided with an adsorption groove 110. The adsorption groove 110 can be used to create a negative pressure and adsorb objects.

[0042] The suction cup may also include a handle 200, at least a portion of which may be integrally formed with the suction cup 100. This design ensures a tighter and more secure connection between the handle 200 and the suction cup 100, preventing separation due to improper installation, loose connection, or damage to the connector. This effectively improves the connection strength between the handle 200 and the suction cup 100. When moving objects, even under significant external force, the handle 200 and the suction cup 100 are less likely to break or separate, thus ensuring safety and stability during object handling.

[0043] In an optional embodiment, the handle 200 may include at least two handle portions 201, which may be located on the side of the suction cup 100 away from the suction groove 110. Each handle portion 201 may be connected to the other in a first direction, and at least one handle portion 201 may be integral with the suction cup 100. Here, the first direction may intersect with the direction from the handle 200 to the suction cup.

[0044] In this embodiment, after the suction cup 100 adsorbs an object, the pulling force generated by the object's own weight is mainly in the adsorption direction. Since the handle portions 201 are connected in a first direction, which intersects the direction from the handle 200 to the suction cup 100, the connection direction of each handle portion 201 intersects the adsorption direction. This prevents the connection structure between the handle portions 201 from directly bearing the pulling force of the object's weight. This effectively reduces stress concentration at the connection points of the handle portions 201 due to gravity, lowering the risk of breakage due to excessive force and ensuring the structural stability of the handle 200. Furthermore, dividing the handle 200 into at least two handle portions 201 facilitates the disassembly and assembly of the internal structure of the suction cup, and if one is damaged, only the damaged part needs to be replaced, without replacing the entire unit.

[0045] In other embodiments, the handle 200 may not include the handle portion 201, and the handle 200 may be an integral structure with the suction cup 100.

[0046] In optional embodiments of this application, such as Figure 2 and Figure 3 As shown, the suction cup 100 may include at least two disc bodies 1001, each disc body 1001 being able to be connected to the other along a first direction. Each handle 201 is one-to-one with each disc body 1001, and each handle 201 is integrally formed with its corresponding disc body 1001. This configuration, on the one hand, eliminates the need for screws or other connectors to connect the handle 200 and the suction cup 100 in the suction direction, further improving the connection strength between the handle 200 and the suction cup 100 in the suction direction; on the other hand, since each handle 201 and its corresponding disc body 1001 are integrally formed, they can be directly cast or injection molded during manufacturing to form an integral handle 201 and disc body 1001, thus facilitating processing.

[0047] In other embodiments, the suction cup 100 may also be a single unit, with only one handle portion 201 being an integral structure with the suction cup 100.

[0048] In optional embodiments, such as Figure 12 As shown, one of the two adjacent disc sections 1001 may be provided with a first connecting groove 1012, such as... Figure 13As shown, the other part can be provided with a first protrusion 1022, which protrudes from the disc body 1001 along a first direction. The first protrusion 1022 is embedded in the first connecting groove 1012, and in the direction from the handle 200 to the suction cup 100, the first protrusion 1022 is matched with the groove wall of the first connecting groove 1012. This arrangement can improve the connection strength of each disc body 1001 and prevent relative movement of each disc body 1001, making it less likely for the disc body 1001 to wobble or misalign, thereby improving the structural stability and reliability of the entire suction cup 100.

[0049] Of course, the first connecting groove 1012 and the first protrusion 1022 may not be provided on each disc body 1001.

[0050] Optionally, such as Figure 12 As shown, one of the two adjacent handle portions 201 may be provided with a second connecting groove 213, such as... Figure 14 As shown, the other part can be provided with a second protrusion 223, which protrudes from the handle part 201 along the first direction. The second protrusion 223 is embedded in the second connecting groove 213, and in the direction from the handle 200 to the suction cup 100, the second protrusion 223 is matched with the groove wall of the second connecting groove 213. This arrangement can improve the connection strength of each handle part 201 and prevent relative movement of each handle part 201, making it less likely for the handle parts 201 to wobble or misalign, thereby improving the structural stability and reliability of the entire handle 200.

[0051] Of course, each handle portion 201 may also omit the second connecting groove 213 and the second protrusion 223.

[0052] In optional embodiments, such as Figure 1 , Figure 12 and Figure 14 As shown, one of two adjacent disc portions 1001 can be provided with a first connecting portion 1011, and the other can be provided with a second connecting portion 1021. The first connecting portion 1011 and the second connecting portion 1021 can be respectively provided on the outer edge of the corresponding disc portion 1001, and the first connecting portion 1011 and the second connecting portion 1021 can be detachably connected by a fastener 107. This arrangement can further improve the connection stability of each disc portion 1001, thereby improving the structural stability of the suction cup 100. In addition, since the first connecting portion 1011 and the second connecting portion 1021 are detachably connected, when one of the disc portions 1001 or the handle portion 201 is damaged, only the damaged part can be replaced, which helps to extend the service life of the suction cup.

[0053] In other embodiments, each disk portion 1001 may not have a first connecting portion 1011 and a second connecting portion 1021.

[0054] Optionally, each handle portion 201 can be connected along the first direction by fasteners such as screws to further improve the connection strength of each handle portion 201.

[0055] In optional embodiments of this application, such as Figures 1-3 As shown, the adsorption tank 110 may include at least two adsorption sub-tanks 111, each of which is independent of the others. This arrangement allows each adsorption sub-tank 111 to simultaneously generate adsorption, increasing the effective adsorption area and enabling the suction cup 100 to more firmly grasp and transport heavier or smoother objects, thus improving the reliability of the suction cup operation. Furthermore, when one or more adsorption sub-tanks 111 leak air, the other non-leaking adsorption sub-tanks 111 can still maintain an independent negative pressure state, continuing to generate sufficient suction to adsorb objects. This effectively reduces the risk of objects falling off due to air leakage, improving the reliability and stability of the suction cup operation. Simultaneously, the required adsorption force may vary under different working environments and task requirements. The multiple adsorption sub-tanks 111 allow the suction cup 100 to flexibly adjust the adsorption force. When a larger adsorption force is needed, all adsorption sub-tanks 111 can be activated, while in situations where lower adsorption force is required, only some adsorption sub-tanks 111 can be activated, thereby saving energy and reducing damage to objects.

[0056] In other embodiments, the adsorption tank 110 may also be an integral whole. For example, the various disk portions 1001 may be connected to form an adsorption tank 110.

[0057] Optionally, such as Figure 2 and Figure 3 As shown, each disk portion 1001 may be provided with at least one adsorption sub-groove 111. This arrangement allows the adsorption sub-groove 111 to be evenly distributed on each disk portion 1001, making the pressure distribution between the suction cup 100 and the object surface more uniform; furthermore, it allows the external force applied by the object to the suction cup 100 to be more evenly distributed on each disk portion 1001, thereby avoiding local stress concentration.

[0058] Of course, at least one adsorption sub-groove 111 is provided on only one or part of the disc body 1001.

[0059] Optionally, such as Figure 3As shown, multiple reinforcing ribs 1111 can be provided on the bottom wall of each adsorption sub-slot 111, which can improve the structural strength of each disc body 1001. Here, in the direction from the handle 200 to the suction cup 100, the support member 500 described below protrudes from the reinforcing ribs.

[0060] In optional embodiments, such as Figure 1 As shown, the suction cup may further include an annular flexible sealing part 300, which surrounds the adsorption groove 110. The first surface of the annular flexible sealing part 300 is used to contact the object. This configuration allows the annular flexible sealing part 300 to better conform to the object's surface, filling any unevenness or tiny gaps that may exist on the surface, thus forming a more effective seal. Even when the object's surface has a certain degree of roughness or irregular shape, the annular flexible sealing part 300 can maintain the seal between the adsorption groove 110 and the object through its own deformation, thereby reducing the possibility of air leakage and further improving the stability of the suction cup 100's adsorption of the object.

[0061] In other embodiments, the suction cup may also exclude the annular flexible seal 300.

[0062] Optionally, such as Figures 10-14 As shown, each disk body 1001 can be provided with a first mounting slot 1051, such as Figure 2 and Figure 9 As shown, each of the first mounting grooves 1051 is aligned to form an annular groove 105. The annular groove 105 surrounds the adsorption groove 110. A portion of the annular flexible sealing part 300 can be embedded in the annular groove 105, and the second surface of the annular flexible sealing part 300 can be connected to the groove wall of the annular groove 105. In this embodiment, the annular groove 105 can provide a precise installation position for the annular flexible sealing part 300, enabling the annular flexible sealing part 300 to be stably connected to each disc part 1001, thereby improving the stability of the annular flexible sealing part 300. At the same time, the annular flexible sealing part 300 can also play a certain limiting role for each disc part 1001, thereby improving the connection stability of each disc part 1001.

[0063] Here, the second surface of the annular flexible sealing part 300 is opposite to the first surface of the annular flexible sealing part 300.

[0064] In other embodiments, each disk portion 1001 may not have a first mounting slot 1051.

[0065] In optional embodiments, such as Figure 5 and Figure 6As shown, the suction cup may further include an annular fixing plate 600, which can be embedded in the annular groove 105, and the annular flexible sealing part 300 can be connected to the annular fixing plate 600. With this configuration, since the annular fixing plate 600 has a certain rigidity and is not easily deformed, it can provide support for the annular flexible sealing part 300, ensuring the stability of its shape and facilitating its assembly into the annular groove 105. Here, the annular flexible sealing part 300 can be connected to the bottom wall of the annular groove 105 via the annular fixing plate 600.

[0066] In this embodiment, the stiffness of the annular fixing plate 600 is greater than the stiffness of the annular flexible sealing part 300, and the annular fixing plate 600 can be an annular metal plate.

[0067] In other embodiments, the suction cup may also exclude the annular fixing plate 600.

[0068] In some embodiments, the annular fixing plate 600 can be detachably connected to each disc body 1001. With this configuration, when the annular flexible sealing part 300 wears, ages or is damaged due to long-term use, it can be easily removed from the suction cup 100 by disassembling the annular fixing plate 600 for replacement. This allows for timely replacement of the annular flexible sealing part 300 to restore the sealing performance of the suction cup 100 and avoid air leakage caused by damage to the sealing part.

[0069] Optionally, the annular fixing plate 600 can be detachably connected to each disk portion 1001 via a magnetic component, or the annular fixing plate 600 can be snapped into each disk portion 1001.

[0070] In optional embodiments, such as Figure 2 As shown, a second mounting groove 106 can be formed between adjacent adsorption sub-grooves 111. The suction cup may also include an intermediate flexible sealing part 400, a portion of which can be embedded in the second mounting groove 106. The first surface of the intermediate flexible sealing part 400 is used to contact the object, and the second surface is connected to the groove wall of the second mounting groove 106. This arrangement allows the intermediate flexible sealing part 400 to be located between two adjacent adsorption sub-grooves 111, ensuring the sealing of each adsorption sub-grooves 111 and thus ensuring the independence of each adsorption sub-grooves 111, making it less likely for them to interfere with each other. Here, the first surface and the second surface of the intermediate flexible sealing part 400 face away from each other.

[0071] Of course, the suction cup may also exclude the intermediate flexible sealing part 400.

[0072] Optionally, such as Figure 2As shown, the second installation groove 106 can communicate with the annular groove 105, and the middle flexible sealing portion 400 can be connected to the annular flexible sealing portion 300. With this arrangement, on the one hand, the stability of the fixation of the middle flexible sealing portion 400 and the sealing performance of each adsorption sub-groove 111 can be improved; on the other hand, the connection stability of each disk body portion 1001 can be further enhanced.

[0073] In some embodiments, the middle flexible sealing portion 400 and the annular flexible sealing portion 300 can be of an integral structure. With this arrangement, the structural strength of the annular flexible sealing portion 300 and the middle flexible sealing portion 400, as well as the connection stability between the annular flexible sealing portion 300, the middle flexible sealing portion 400, and the suction cup 100, can be improved. Exemplarily, in the case where the adsorption groove 110 includes two adsorption sub-grooves 111, the annular flexible sealing portion 300 and the middle flexible sealing portion 400 form a "day" - shaped structure.

[0074] Further optionally, as Figure 6 shown, the suction cup device can further include a middle fixing plate 700. The middle fixing plate 700 can be embedded in the second installation groove 106, and the middle flexible sealing portion 400 is connected to the middle fixing plate 700. With this arrangement, since the middle fixing plate 700 has a certain rigidity and is not easily deformed, the middle fixing plate 700 can play a certain supporting role for the middle flexible sealing portion 400 to ensure the shape of the middle flexible sealing portion 400 remains stable, thereby facilitating the assembly of the middle flexible sealing portion 400 into the second installation groove 106. Here, the middle flexible sealing portion 400 can be connected to the bottom wall of the second installation groove 106 through the middle fixing plate 700.

[0075] In this embodiment, the rigidity of the middle fixing plate 700 is greater than that of the middle flexible sealing portion 400. The middle fixing plate 700 can be a metal plate.

[0076] In some embodiments, as Figure 6 shown, the middle fixing plate 700 can be connected to the annular fixing plate 600. In this way, when disassembling and assembling the annular flexible sealing portion 300 and the middle flexible sealing portion 400, they can be disassembled and assembled simultaneously, so as to improve the assembly efficiency; and the connection strength between the annular flexible sealing portion 300 and the middle flexible sealing portion 400 can also be enhanced.

[0077] Exemplarily, the middle fixing plate 700 and the annular fixing plate 600 can be an integral structure. With such a setting, the connection strength between the annular flexible sealing portion 300 and the middle flexible sealing portion 400 can be further improved, making it difficult for the annular flexible sealing portion 300 and the middle flexible sealing portion 400 to break; at the same time, it can also play a role in limiting the position of each disk body portion 1001 to improve the connection stability of each disk body portion 1001. Optionally, when the adsorption groove 110 includes two adsorption sub-grooves 111, the annular fixing plate 600 and the middle fixing plate 700 are formed into a "day" - shaped structure.

[0078] In an alternative embodiment of the present application, as Figures 1-3 shown, the suction cup device can further include at least two support members 500. Each support member 500 is respectively arranged around the adsorption sub - groove 111, and the first surface of each support member 500 can be used to contact the surface of the object, and the second surface of each support member 500 can be connected to the suction cup 100. Among them, the stiffness of each support member 500 is greater than the stiffness of the annular flexible sealing portion 300 and the middle flexible sealing portion 400. The support member 500 in this embodiment can play a role in limiting and supporting the object to avoid the object from being deformed or broken due to excessive local pressure on the object. At the same time, the support member 500 can also prevent the annular flexible sealing portion 300 and the middle flexible sealing portion 400 from being deformed too much to seal the adsorption sub - groove 111.

[0079] Here, a middle flexible sealing portion 400 is provided between two adjacent support members 500.

[0080] In this embodiment, the stiffness of the support member 500 can be less than the stiffness of the suction cup 100. With such a setting, the support member 500 can play a role in limiting and supporting the object, and can also avoid the support member 500 from causing damage to the object due to rigid contact with the object.

[0081] Exemplarily, the support member 500 can be made of materials such as silica gel or rubber, and the annular flexible sealing portion 300 and the middle flexible sealing portion 400 can be made of materials such as foam or sponge.

[0082] Among them, as Figure 7 and Figure 8 shown, each support member 500 can include an arc - shaped support portion 510 and a strip - shaped support portion 520. The two ends of the strip - shaped support portion 520 can be connected to the two ends of the arc - shaped support portion 510 to form a D - shaped structure. Among them, the arc - shaped support portions 510 of the two support members 500 can be located on the same ring, and the strip - shaped support portions 520 can be located between the two arc - shaped support portions 510. With such a setting, the strip - shaped support portion 520 can be located in the middle of the suction cup 100 to be used for limiting and supporting the position corresponding to the middle of the surface of the object and the suction cup 100. In this embodiment, the suction cup device can include two support members 500.

[0083] Optionally, such as Figure 9 As shown, the suction cup 100 may be provided with at least two third mounting slots 108, each corresponding to one of the support members 500. A portion of each support member 500 can be embedded in its corresponding third mounting slot 108, and the second surface of the support member 500 can be connected to the wall of the third mounting slot 108. In this embodiment, the third mounting slot 108 provides a precise mounting position for the support member 500, enabling it to be securely connected to the suction cup 100. Here, the second surface of the support member 500 is opposite to its first surface.

[0084] In some embodiments, each disc portion 1001 may be provided with at least one third mounting groove 108, which surrounds the adsorption sub-groove 111.

[0085] Optionally, such as Figure 3 , Figure 7 and Figure 8 As shown, multiple contact protrusions 530 can be provided on the first surface of the support member 500. This arrangement increases the friction between the object and the support member 500, thereby preventing relative movement between the object and the suction cup 100 when the suction cup adsorbs the object. For example, a connecting gap can be formed between two adjacent contact protrusions 530, and each connecting gap can communicate with the adsorption sub-groove 111, so that the space between the annular flexible sealing part 300 and the support member 500 can communicate with the adsorption sub-groove 111.

[0086] In an optional embodiment, the suction cup further includes a wrapping reinforcement 230, which partially wraps around at least a portion of the handle 200 and connects to each handle portion 201. This arrangement can improve the connection strength of each handle portion 201, thereby improving the structural strength of the handle 200.

[0087] Of course, the suction cup may not include the wrapping reinforcement 230.

[0088] In optional embodiments, such as Figure 11 and Figure 14 As shown, each handle portion 201 may include a handle connecting portion 2011 and a handle forming portion 2012 that is integral with the handle connecting portion 2011. The handle connecting portion 2011 and the suction cup 100 may be integral with each other. The handle forming portion 2012 of each handle portion 201 is connected to form a handle grip portion 202.

[0089] At least some of the handle portions 201 and their connecting portions 2011 can be aligned to form an assembly space. For example... Figures 10-14As shown, the suction cup may also include an air extraction device 800, which may be disposed in the assembly space and may be connected to the adsorption tank 110 and may be used to create a negative pressure in the adsorption tank 110.

[0090] In this embodiment, the suction device 800 is placed in the assembly space formed by the docking of the handle connection 2011, which can make full use of the space of the handle 200, avoid occupying additional external space, and help reduce the overall volume of the suction cup.

[0091] Of course, the connection between the handle connecting parts 2011 may not form an assembly space, and the air extraction device 800 may be set outside the handle 200.

[0092] Optionally, such as Figure 10 and Figure 13 As shown, the suction cup may further include a grip reinforcement 240, which may be disposed outside the handle grip portion 202 and may be connected to the handle forming portion 2012 of each handle portion 201. This arrangement can improve the structural strength of the handle grip portion 202.

[0093] In some embodiments, such as Figures 2-4 As shown, the suction cup 100 may include two disc bodies 1001, which may be a first disc body 101 and a second disc body 102, respectively. The first disc body 101 and the second disc body 102 may be connected along a first direction. The suction cup may include two handles 201, which may be a first handle 210 and a second handle 220, respectively. The first handle 210 and the first disc body 101 may be an integral structure, and the second handle 220 and the second disc body 102 may be an integral structure.

[0094] Optionally, such as Figure 4 As shown, at least one rope connector 1100 can be provided on the first disc body 101 and at least one rope connector 1100 can be provided on the second disc body 102. When the suction cup 100 picks up a heavy object, a rope can be connected to the rope connector 1100 and the lifting rod can be connected to the rope so that multiple operators can move it together.

[0095] In this embodiment, as Figure 11 and Figure 12 As shown, the first handle portion 210 may include two first handle connecting portions 211, which can be connected to both ends of the first handle forming portion 212, and both first handle connecting portions 211 can be connected to the first tray body portion 101. Figure 13 and Figure 14As shown, the second handle portion 220 may include two second handle connecting portions 221, which can be connected to both ends of the second handle forming portion 222 respectively, and both second handle connecting portions 221 can be connected to the second plate body portion 102.

[0096] Here, the rope connector 1100 can be located between the two first handle connectors 211.

[0097] Optionally, such as Figure 10 and Figure 11 As shown, the suction cup may also include a power supply 900, which may be located on one side of the handle 200 and may be connected to the first handle connection portion 211 of the first handle portion 210 and the second handle connection portion 221 of the second handle portion 220. The power supply 900 can be used to supply power to the suction device 800. Specifically, the interior of the handle grip portion 202 has a channel for the passage of a wire electrically connected to the power supply 900. The channel communicates with the assembly space so that the wire can enter the assembly space and electrically connect to the suction device 800.

[0098] In an optional embodiment, the suction cup may further include a control switch electrically connected to the vacuum device 800, and the control switch is located on the side of the assembly space away from the suction cup 100 for easy operation by the operator.

[0099] The suction cup may also include a locking component, which can be located on the side of the assembly space opposite to the suction cup 100. The locking component can lock the control switch. This arrangement can prevent accidental activation of the control switch.

[0100] In other embodiments, the suction cup may also exclude the locking component.

[0101] For example, such as Figure 10 , Figure 11 and Figure 13 As shown, a fixed support plate 1000 can be provided above the assembly space. The fixed support plate 1000 is connected to the first handle connecting part 211 and the second handle connecting part 221, and the control switch and locking assembly can be provided on the fixed support plate 1000.

[0102] In one embodiment, the locking assembly may include a knob and a baffle connected to the knob. The knob may be rotatably connected to a fixed support plate 1000, and the knob may cause the baffle to rotate between a first angle and a second angle. When the baffle is rotated to the first angle, the baffle may cover the control switch to prevent the user from triggering the control switch. When the baffle is rotated to the second angle, the baffle may avoid the control switch so that the user can trigger the control switch.

[0103] In another embodiment, the locking assembly may include a toggle part and a sliding part connected to the toggle part. The sliding part is slidably connected to the fixed support plate 1000, and the toggle part can drive the sliding part to slide between a first position and a second position. When the sliding part is in the first position, the sliding part extends between the keycap of the control switch and the fixed support plate 1000 to restrict the movement of the keycap, thereby locking the control switch and preventing the control switch from being triggered. When the sliding part is in the second position, the sliding part avoids the control switch, allowing the control switch to be triggered.

[0104] Of course, the locking component can also be other structures capable of locking the control switch.

[0105] In an optional embodiment of this application, the suction cup 100 may be provided with at least two vent holes 103, each vent hole 103 being connected to each adsorption sub-slot 111. The suction cup 100 may also be provided with a vent valve, the vent hole 103 being connected to the vent valve, which can be used to control the opening and closing of the vent hole 103. In this embodiment, the operator can regulate the pressure of the adsorption sub-slot 111 by controlling the vent valve, thereby controlling the adsorption and release states of the adsorption sub-slot 111.

[0106] Optionally, the suction cup 100 may be equipped with at least two vent valves, each of which can be connected to a vent hole 103 in a one-to-one correspondence, so that each vent valve can independently control the pressure of an adsorption sub-slot 111. This configuration ensures that each adsorption sub-slot 111 has an independent vent hole 103 and vent valve, allowing operators to precisely control the adsorption and release states of each adsorption sub-slot 111. For example, when handling irregularly shaped objects, only some adsorption sub-slots 111 may need to provide adsorption force to fix the object, while other adsorption sub-slots 111 can remain in a released state. By independently controlling the vent valves, the working state of the adsorption sub-slots 111 can be flexibly adjusted to meet the adsorption needs of objects of different shapes and sizes, improving operational accuracy and adaptability. Furthermore, in some complex adsorption scenarios, the adsorption force can be adjusted in stages according to the weight, material, or different stages of the handling process. By controlling the opening and closing time and degree of different vent valves, staged adsorption and release of the adsorption sub-slots 111 can be achieved. For example, when lifting heavy objects, some vent valves can be closed first to allow some adsorption sub-slots 111 to generate adsorption force. After the object stabilizes, the other vent valves can be closed to increase the adsorption force. When releasing the object, the vent valves can be opened in a certain order to achieve a smooth release and avoid the object from shaking or being damaged due to the sudden disappearance of the adsorption force.

[0107] In other embodiments, the suction cup 100 may not have a vent hole 103, and each suction sub-slot 111 may be vented by the suction device 800.

[0108] In some embodiments, the suction cup 100 is provided with at least two vent holes 103. The suction cup 100 may also include a venting pipeline, which includes a main venting pipeline and at least two venting branches. The first end of each venting branch is connected to the corresponding vent hole 103, and the second end of each venting branch can be connected to the main venting pipeline. Furthermore, the suction cup 100 may only be provided with one venting valve, which is located on the main venting pipeline and used to control the opening and closing of the main venting pipeline. That is, multiple vent holes 103 can be controlled to vent simultaneously through one venting valve.

[0109] In an optional embodiment, the suction cup 100 may be provided with at least two suction holes 104, each suction hole 104 corresponding to a suction sub-slot 111, and each suction sub-slot 111 communicating with the suction device 800 through its corresponding suction hole 104. The suction cup 100 may also be provided with a control valve, which may communicate with the suction hole 104 and be used to control the connection between the suction hole 104 and the suction device 800.

[0110] In other embodiments, the suction cup 100 may not be equipped with a control valve, and the air extraction device 800 may simultaneously extract air from each adsorption sub-slot 111 through the air extraction hole 104.

[0111] Optionally, the suction cup may also include a pressure detection module for detecting the pressure within the adsorption sub-slot 111. The pressure detection module can communicate with a control valve, and the control valve opens when the pressure detection module detects that the pressure in the adsorption sub-slot 111 is lower than a preset pressure. This configuration automatically adjusts the pressure within the adsorption sub-slot 111, preventing the pressure from becoming too low and reducing the adsorption effect of the suction cup 100, thus causing objects to fall.

[0112] Of course, the suction cup may also not include a pressure detection module.

[0113] Optionally, the suction cup 100 may be equipped with at least two control valves, each control valve being connected to a corresponding suction port 104, and each control valve being used to control the connection and disconnection between the corresponding suction port 104 and the suction device 800. In this embodiment, each adsorption sub-slot 111 is equipped with an independent suction port 104 and a control valve, enabling the operator to precisely control the adsorption state of each adsorption sub-slot 111. When handling irregularly shaped objects, only a portion of the adsorption sub-slots 111 may be needed to provide adsorption force to fix the object. By closing the control valves corresponding to the adsorption sub-slots 111 that do not need to work, these adsorption sub-slots 111 can be prevented from participating in adsorption, thereby achieving precise selection of the adsorption area to meet the adsorption needs of objects of different shapes and sizes.

[0114] The pressure detection module may include at least two pressure detection elements, each of which can be communicatively connected to a corresponding control valve. When the pressure detection element detects that the pressure of the corresponding adsorption sub-tank 111 is less than the preset pressure, the control valve corresponding to the pressure detection element opens.

[0115] During the adsorption process, when the adsorption force of different adsorption sub-cells 111 is uneven due to some factors (such as uneven surface of the object or local air leakage), each pressure detection element can monitor the pressure in each adsorption sub-cell 111 in real time. When the pressure of some adsorption sub-cells 111 is less than the preset pressure, it indicates that the adsorption force of the adsorption sub-cell 111 may be too small or there is an abnormality. At this time, the control valve corresponding to the adsorption sub-cell 111 opens, which can increase the adsorption force of the adsorption sub-cell 111. In this way, the adsorption force of each adsorption sub-cell 111 can be made to be approximately the same, thereby improving the overall adsorption stability of the suction cup 100 and ensuring that the object is firmly adsorbed.

[0116] Furthermore, the required adsorption force varies when adsorbing objects of different materials, shapes, or weights. In this case, the linkage between each pressure detection element and each control valve can automatically adjust the pressure of the adsorption sub-slot 111 according to the actual working conditions, so that the suction cup can better adapt to various complex situations and ensure the stability of the adsorption effect.

[0117] Of course, the suction cup 100 can also be equipped with only one control valve, with each suction port 104 connected to the control valve. The control valve can control the connection and disconnection between each suction port 104 and the suction device 800. Specifically, each suction port 104 can be connected to the main suction pipeline, which is connected to the suction device 800. The control valve is located on the main suction pipeline. Furthermore, the pressure detection module can also include only one pressure detection element, which can be located on the main suction pipeline to detect the pressure of the adsorption sub-slot 111 by detecting the pressure within the main suction pipeline.

[0118] In some embodiments, each pressure sensing element can also be communicatively connected to each venting valve, and the opening degree of each venting valve can be adjusted according to the detection results of each pressure sensing element. For example, when the pressure of some adsorption sub-slots 111 is too high, when the pressure sensing element detects that the pressure of the adsorption sub-slot 111 is greater than or equal to the critical pressure, the venting valve corresponding to that adsorption sub-slot 111 opens to release the pressure, thereby preventing the adsorption force from being too large and damaging the object.

[0119] In this embodiment, the pressure detection element can be a pressure sensor, and the pumping device 800 can include a vacuum pump.
