Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of handling tools, and particularly relates to a suction cup device. BACKGROUND

[0002] As a labor-saving machine for operating objects by means of negative pressure suction force generated by a vacuum pump, the suction cup device is uniformly adsorbed on the surface of the object by the negative pressure suction force when the suction cup device is in contact with the object, and does not cause mechanical damage to the object, so that the surface quality of the object can be well protected. In addition, the operation of adsorbing and releasing the object by the suction cup is rapid, and the grabbing and releasing of the object can be completed in a short time, so that the production efficiency is greatly improved. More importantly, the suction cup device has no strict limitation on the types of object materials, and can effectively adsorb objects whether they are metal, non-metal, smooth surface or rough surface, and has wide applicability.

[0003] In the related art, the suction cup of the suction cup device is mostly an integral structure. Once air leakage occurs at a certain position of the suction cup, the negative pressure environment in the entire suction cup will be destroyed, the suction force between the suction cup and the object will be rapidly lost, and then the object will fall off, which not only may cause damage to the object, but also may pose a threat to the safety of surrounding personnel and equipment. SUMMARY

[0004] The purpose of the embodiments of the application is to provide a suction cup device which can solve the problem that the object is easily caused to fall off after air leakage of the suction cup in the related art.

[0005] The embodiments of the application provide a suction cup device, which comprises: a suction cup body provided with at least two adsorption cavities, and each adsorption cavity is independent of each other; an adsorption assembly, each adsorption cavity is communicated with the adsorption assembly; a flexible sealing piece, which is arranged around the adsorption cavity, and a first surface of the flexible sealing piece is used for contacting with the object; a connecting fixing piece, which is arranged on a second surface of the flexible sealing piece, the second surface of the flexible sealing piece is opposite to the first surface of the flexible sealing piece, and the connecting fixing piece is detachably connected with the suction cup body.

[0006] In the embodiments of the application, the suction cup body is provided with at least two independent adsorption cavities, each adsorption cavity is independently communicated with the adsorption assembly, when air leakage occurs in one or part of the adsorption cavities, the other adsorption cavities which do not leak air can still maintain an independent negative pressure state, continue to generate sufficient suction force to adsorb the object, and then the risk of the object falling off due to air leakage can be effectively reduced, and the reliability and stability of the work of the suction cup device are improved.

[0007] In addition, the flexible sealing ring is arranged around the adsorption cavity and used to contact the object. Since the flexible sealing ring has good flexibility and adaptability, it can better fit the surface of the object to fill the unevenness and small gaps that may exist on the surface of the object, thereby forming a more effective seal. Even if there is a certain degree of roughness or irregular shape on the surface of the object, the flexible sealing ring can ensure the sealing between the adsorption cavity and the object through its own deformation, thereby reducing the possibility of air leakage and further improving the stability of the suction cup device in adsorbing the object.

[0008] Since the connecting and fixing member is detachably connected with the suction cup body, when the flexible sealing ring is worn, aged or damaged due to long-term use, it can be conveniently removed from the suction cup body by detaching the connecting and fixing member for replacement. In this way, a new sealing ring can be replaced in time to restore the sealing performance of the adsorption cavity, thereby avoiding air leakage due to damage of the sealing ring.

DETAILED DESCRIPTION

[0011] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0012] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a class, not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0013] The suction cup provided by the embodiments of the present application will be described in detail below in combination with the drawings, specific embodiments and application scenarios.

[0014] Reference Figures 1-14 The suction cup device provided by the embodiments of the present application can include a suction cup body 100, a suction assembly 600, a flexible sealing member 300 and a connecting and fixing member 500.

[0015] As shown in Figures 1-3 , the suction cup body 100 can be provided with at least two suction cavities 110, each suction cavity 110 can be independent of each other, and each suction cavity 110 is in communication with the suction assembly 600. In this way, on the one hand, each suction cavity 110 can produce a suction effect at the same time, which is equivalent to increasing the effective area of suction, so that the suction cup device can more stably grasp and transport heavy or smooth-surfaced objects, and the reliability of the operation of the suction cup device is improved. On the other hand, when one or part of the suction cavities 110 leaks, the other suction cavities 110 that do not leak can still maintain an independent negative pressure state and continue to generate sufficient suction force to adsorb the object, thereby effectively reducing the risk of the object falling off due to leakage, and improving the reliability and stability of the work of the suction cup device. At the same time, the demand for suction force may be different under different working environments and task requirements, and the setting of multiple suction cavities 110 enables the suction cup device to flexibly adjust the size of the suction force. When a larger suction force is required, all suction cavities 110 can be opened, and in some occasions where the requirement for suction force is low, only part of the suction cavities 110 can be opened, thereby saving energy and reducing damage to the object.

[0016] As shown in Figure 1 , the flexible sealing member 300 can be arranged around the suction cavity 110, the first surface of the flexible sealing member 300 can be used to contact the object; the connecting and fixing member 500 can be arranged on the second surface of the flexible sealing member 300, and the connecting and fixing member 500 can be detachably connected with the suction cup body 100. Here, the second surface of the flexible sealing member 300 is opposite to the first surface of the flexible sealing member 300.

[0017] In the embodiments of the present application, since the flexible sealing member 300 has good flexibility and adaptability, it can better fit the surface of the object to fill the unevenness and small gaps that may exist on the surface of the object, and form a more effective seal. Even if there is a certain degree of roughness or irregular shape on the surface of the object, the flexible sealing member 300 can ensure the sealing between the suction cavity 110 and the object through its own deformation, thereby reducing the possibility of air leakage and further improving the stability of the suction cup device in adsorbing the object.

[0018] Since the connecting and fixing member 500 is detachably connected with the suction cup body 100, when the flexible sealing member 300 is worn, aged or damaged due to long-term use, it can be conveniently removed from the suction cup body 100 by detaching the connecting and fixing member 500 for replacement. In this way, a new flexible sealing member 300 can be replaced in time to restore the sealing performance of the suction cavity 110, thereby avoiding air leakage caused by damage to the flexible sealing member 300.

[0019] In optional embodiments of the present application, as shown in Figures 1-3 The suction cup device can also include a support member 400, which can be provided on the suction cup body 100. The first surface of the support member 400 can be used to contact the object, and the second surface of the support member 400 can be detachably connected with the suction cup body 100. In the direction from the second surface of the support member 400 to the first surface of the support member 400, the second surface of the flexible sealing member 300 protrudes from the second surface of the support member 400, and the rigidity of the support member 400 is greater than the rigidity of the flexible sealing member 300. The support member 400 in this embodiment can function as a limiting support for the object to avoid excessive local pressure that may damage the object. At the same time, the support member 400 can also prevent the flexible sealing member 300 from deforming too much to seal the suction cavity 110. Here, the first surface of the support member 400 is opposite to the second surface of the support member 400.

[0020] In the present embodiment, the rigidity of the support member 400 can be less than the rigidity of the suction cup body 100. In this way, the support member 400 can function as a limiting support for the object, and can also avoid rigid contact with the object that may damage the object.

[0021] For example, the support member 400 can be made of materials such as silica gel or rubber, and the flexible sealing member 300 can be made of materials such as foam or sponge.

[0022] In other embodiments, the suction cup device can also not include the support member 400.

[0023] In optional embodiments, as shown in Figure 1 The support member 400 can include at least two sub-support members 410, as shown in Figures 1-3As shown, each sub-support member 410 can be respectively and correspondingly arranged around the outside of each adsorption cavity 110. The first surface of each sub-support member 410 can be used to contact the object, and the second surface of each sub-support member 410 can be connected to the suction cup body 100. The first surfaces of each sub-support member 410 can be flush. In this embodiment, each sub-support member 410 independently surrounds its corresponding adsorption cavity 110, enabling more precise contact with the surface of the object surrounding the adsorption cavity 110. Each sub-support member 410 can also provide limiting support for the object and distribute the force between the suction cup body 100 and the object to various parts, ensuring uniform force distribution across the object and preventing deformation or even breakage due to excessive local pressure. Here, the first surface and the second surface of the sub-support member 410 face away from each other.

[0024] Of course, the support 400 can also be a single unit, and the support 400 can surround all the flexible seals 300.

[0025] In this embodiment, the support member 400 may include two sub-support members 410, such as... Figure 2 , Figure 7 and Figure 8 As shown, each sub-support member 410 may include an arc-shaped support portion 411 and a long strip support portion 412. The two ends of the long strip support portion 412 can be connected to the two ends of the arc-shaped support portion 411 to form a D-shaped structure. The arc-shaped support portions 411 of two sub-support members 410 can be located on the same ring, and the two long strip support portions 412 can be located between the two arc-shaped support portions 411. With this arrangement, the two long strip support portions 412 can be located in the middle of the suction cup body 100 to limit the position of the supported object surface corresponding to the middle of the suction cup body 100.

[0026] In other embodiments, each sub-support member 410 may include only the arc-shaped support portion 411, excluding the elongated support portion 412.

[0027] In optional embodiments, such as Figure 5 As shown, the flexible sealing element 300 may include a first flexible sealing portion 310 and a second flexible sealing portion 320. The first flexible sealing portion 310 may be disposed around the suction cup body 100, and the second flexible sealing portion 320 may be disposed between two adjacent adsorption cavities 110. In this embodiment, the second flexible sealing portion 320 is located between two adjacent adsorption cavities 110, which can ensure the sealing of each adsorption cavity 110, thereby ensuring the independence of each adsorption cavity 110 and preventing interference between them. Optionally, the second flexible sealing portion 320 may be disposed between two adjacent sub-support members 410.

[0028] In other embodiments, the flexible seal 300 may also include only the first flexible seal portion 310.

[0029] Optionally, the second flexible sealing part 320 is connected to the first flexible sealing part 310. For example, the second flexible sealing part 320 and the first flexible sealing part 310 can be an integral structure. This configuration can improve the structural strength of the flexible sealing element 300 and the connection stability between the flexible sealing element 300 and the suction cup body 100, and can also improve the sealing effect of each suction cavity 110.

[0030] Of course, the second flexible sealing part 320 may not be connected to the first flexible sealing part 310.

[0031] In optional embodiments, such as Figure 9 As shown, at least two fixing grooves 108 can be provided on the suction cup body 100, and each sub-support member 410 can be disposed in each fixing groove 108. In this embodiment, the fixing grooves 108 can provide a precise installation position for the sub-support members 410, so that each sub-support member 410 can be stably surrounded around the suction cavity 110.

[0032] Of course, the suction cup body 100 may not have a fixing groove 108. Each sub-support 410 can be directly connected to the suction cup body 100. For example, each sub-support 410 can be glued to the suction cup body 100 or connected by screws.

[0033] like Figure 2 and Figure 9 As shown, the suction cup body 100 may also be provided with a first mounting groove 105, and a portion of the first flexible sealing part 310 may be embedded in the first mounting groove 105; a second mounting groove 106 may be formed between two adjacent sub-support members 410, the second mounting groove 106 may communicate with the first mounting groove 105, and a portion of the second flexible sealing part 320 may be embedded in the second mounting groove 106. In this embodiment, the first mounting groove 105 can provide a precise mounting position for the first flexible sealing part 310, so that the first flexible sealing part 310 can be stably connected to the suction cup body 100, and the second mounting groove 106 can provide a precise mounting position for the second flexible sealing part 320, ensuring that the second flexible sealing part 320 can be stably installed.

[0034] Of course, the first mounting slot 105 may not be provided on the suction cup body 100.

[0035] In optional embodiments, such as Figure 6As shown, the connecting fastener 500 may include a first fixing part 510 and a second fixing part 520. The first fixing part 510 may be connected to the first flexible sealing part 310. The first fixing part 510 may be embedded in the first mounting groove 105 and may be detachably connected to the bottom wall of the first mounting groove 105. The second fixing part 520 may be connected to the second flexible sealing part 320. The second fixing part 520 may be embedded in the second mounting groove 106 and may be detachably connected to the bottom wall of the second mounting groove 106. With this configuration, since the first fixing part 510 and the second fixing part 520 have a certain rigidity and are not easily deformed, the first fixing part 510 can provide a certain support for the first flexible sealing part 310 to ensure that the shape of the first flexible sealing part 310 remains stable, thereby facilitating the assembly of the first flexible sealing part 310 into the first mounting groove 105. The second fixing part 520 can provide a certain support for the second flexible sealing part 320 to ensure that the shape of the second flexible sealing part 320 remains stable, thereby facilitating the assembly of the second flexible sealing part 320 into the second mounting groove 106.

[0036] Furthermore, the first fixing part 510 and the second fixing part 520 can be connected; optionally, the first fixing part 510 and the second fixing part 520 can be an integral structure. This configuration allows for integral installation of the flexible seal 300, improving the ease of installation; it also enhances the connection stability of the first flexible seal 310 and the second flexible seal 320, preventing them from breaking or separating.

[0037] In other embodiments, the connecting fastener 500 may also include only the first fastening part 510 or the second fastening part 520.

[0038] Alternatively, if the connecting fastener 500 includes a first fixing part 510 and a second fixing part 520, the first fixing part 510 and the second fixing part 520 may not be connected.

[0039] In some embodiments, the dimension of the portion of the flexible seal 300 protruding from the support 400 in the direction from the second surface of the support 400 to the first surface of the support 400 may be smaller than the dimension of the flexible seal 300 in the direction from the flexible seal 300 to the support 400. This configuration, on the one hand, increases the contact area between the flexible seal 300 and the object surface, allowing the flexible seal 300 to better adapt to the shape of the object surface and improving the sealing performance between the flexible seal 300 and the object surface; on the other hand, it also increases the strength of the flexible seal 300, preventing excessive deformation that would render it ineffective in sealing.

[0040] Of course, the dimension of the portion of the flexible seal 300 protruding from the support 400 in the direction from the second surface of the support 400 to the first surface of the support 400 may also be greater than or equal to the dimension of the flexible seal 300 in the direction from the flexible seal 300 to the support 400.

[0041] In optional embodiments, such as Figure 3 As shown, a reinforcing rib 111 can be provided on the suction cup body 100. The reinforcing rib 111 can be located within the suction cavity 110, thereby improving the structural strength of the suction cup body 100. Furthermore, the support member 400 protrudes beyond the reinforcing rib 111 along the direction from the second surface of the support member 400 to the first surface of the support member 400. In this way, the reinforcing rib 111 will not come into contact with the surface of the object, thus preventing damage to the surface of the object.

[0042] Of course, the suction cup body 100 may not have a reinforcing rib 111.

[0043] Optionally, such as Figure 3 As shown, the first surface of the support member 400 is provided with a plurality of spaced protrusions 420. This arrangement increases the friction between the object and the support member 400, thereby preventing relative movement between the object and the suction cup body 100 when the object is adsorbed.

[0044] Of course, the first surface of the support member 400 may not have a protrusion 420.

[0045] In an optional embodiment, the connecting fastener 500 is magnetically connected or snapped into the suction cup body 100. This configuration eliminates the need for tools when assembling or disassembling the connecting fastener 500, thereby improving the ease of assembly and disassembly of the connecting fastener 500, and consequently, the ease of assembly and disassembly of the flexible seal 300.

[0046] Of course, the connecting fastener 500 and the suction cup body 100 can also be connected by fixing screws.

[0047] In optional embodiments of this application, such as Figure 1 As shown, the suction cup device may also include a grip handle 200, which can be connected to the suction cup body 100. The grip handle 200 can be located on the side of the suction cup body 100 away from the suction cavity 110, so as to facilitate the operator's grip.

[0048] like Figure 2 As shown, the suction cup body 100 may include a first disc body portion 101 and a second disc body portion 102. The first disc body portion 101 and the second disc body portion 102 may be connected to each other along the width direction of the suction cup device, and at least one suction cavity 110 may be provided on both the first disc body portion 101 and the second disc body portion 102.

[0049] The grip handle 200 may include a first grip portion 210 and a second grip portion 220, which can be connected to each other along the width direction of the suction cup device to form the grip handle 200. The first grip portion 210 and the first disk body portion 101 can be an integral structure, and the second grip portion 220 and the second disk body portion 102 can be an integral structure. This configuration eliminates the need for screws or other fasteners to connect the grip handle 200 and the suction cup body 100. On the one hand, this avoids the grip handle 200 from separating from the suction cup body 100 due to damage or loosening of screws or other fasteners, which could cause objects to fall during transport. On the other hand, it better disperses stress and reduces stress concentration, thereby lowering the risk of damage to both the grip handle 200 and the suction cup body 100.

[0050] In optional embodiments, such as Figure 12 As shown, a first limiting groove 1012 may be provided on the first disc body 101, such as... Figure 13 and Figure 14 As shown, a first limiting part 1022 may be provided on the second disc body 102. A first limiting groove 1012 may be opened along the width direction of the suction cup device. The first limiting part 1022 may protrude from the second disc body 102 along the width direction of the suction cup device. The first limiting part 1022 may be embedded in the first limiting groove 1012, and in the direction from the grip handle 200 to the suction cup body 100, the first limiting part 1022 and the groove wall of the first limiting groove 1012 are mutually limiting and engaged. This arrangement can improve the connection strength between the first disc body 101 and the second disc body 102, and prevent relative movement between the first disc body 101 and the second disc body 102, making it less likely for the first disc body 101 and the second disc body 102 to wobble or misalign, thereby improving the structural stability and reliability of the entire suction cup body 100.

[0051] Optionally, such as Figures 9-12 As shown, a first connecting portion 1011 may also be provided on the first disk body portion 101, such as... Figure 9 , Figure 13 and Figure 14 As shown, a second connecting part 1021 may also be provided on the second disc body 102. The first connecting part 1011 and the second connecting part 1021 can be connected by fasteners 107. This arrangement can further improve the connection stability of the first disc body 101 and the second disc body 102, thereby improving the structural stability of the suction cup body 100.

[0052] Optionally, a second limiting groove may be provided on the first gripping part 210, and a second limiting part may be provided on the second gripping part 220. The second limiting groove may be opened along the width direction of the suction cup device, and the second limiting part may protrude from the second gripping part 220 along the width direction of the suction cup device. The second limiting part may be embedded in the second limiting groove, and in the direction from the gripping handle 200 to the suction cup body 100, the second limiting part and the groove wall of the second limiting groove are mutually limitingly engaged. This configuration can improve the connection strength between the first gripping part 210 and the second gripping part 220, and prevent relative movement between the first gripping part 210 and the second gripping part 220, making it less likely for the first gripping part 210 and the second gripping part 220 to wobble or misalign. This can improve the stability and reliability of the gripping handle 200, thereby further improving the connection stability between the gripping handle 200 and the suction cup body 100.

[0053] Optionally, such as Figure 11 and Figure 12 As shown, the first gripping part 210 may include a first portion 211 and a second portion 212 integrally formed with the first portion 211. The first portion 211 may be integrally formed with the first disc body 101. Figure 14 As shown, the second gripping part 220 may include a third part 221 and a fourth part 222 integrally formed with the third part 221. The third part 221 may be integrally formed with the first disc body part 101. Furthermore, the first part 211 and the third part 221 may be joined in the width direction of the suction cup device, and the second part 212 and the fourth part 222 may be joined in the width direction of the suction cup device to form a gripping rod for the operator to hold.

[0054] In some embodiments, an installation cavity may be formed between the first portion 211 and the third portion 221, and the adsorption assembly 600 may be disposed in the installation cavity.

[0055] Further, alternatively, to improve the structural strength of the grip handle 200, such as Figure 10 As shown, the grip handle 200 may also include a first grip reinforcement 230, which may cover at least a portion of the grip bar and may be connected to the second portion 212 and the fourth portion 222, respectively.

[0056] The first handle reinforcement 230 can also be connected to the first part 211 and the third part 221, which can further improve the structural strength of the grip handle 200.

[0057] In this embodiment, to facilitate the installation of the first handle reinforcement 230, the first handle reinforcement 230 can be divided into two parts. For example, the first handle reinforcement 230 may include a first reinforcing structure and a second reinforcing structure. The first reinforcing structure may cover at least a portion of the first grip portion 210 and be connected to the first grip portion 210. The second reinforcing structure may cover at least a portion of the second grip portion 220 and be connected to the second grip portion 220. Furthermore, the first and second reinforcing structures can be aligned along the width direction of the suction cup device. Optionally, the first handle reinforcement 230 may cover the fixing plate 800 described below, as well as portions of the first portion 211 and the third portion 221, to form a sealed space for the mounting cavity. It should be noted that one of the first portion 211 and the third portion 221 may be provided with a through hole, and the air outlet of the adsorption assembly 600 may communicate with the through hole to facilitate exhaust.

[0058] For example, such as Figure 10 As shown, the grip handle 200 may also include two second grip reinforcement members 240, which may be respectively disposed outside the second part 212 and the fourth part 222, and the two second grip reinforcement members 240 may be connected to each other along the width direction of the suction cup device. This arrangement can further improve the structural strength of the grip rod.

[0059] In optional embodiments, such as Figure 4 As shown, at least one rope connector 900 can be provided on the first disc body 101 and at least one rope connector 900 can be provided on the second disc body 102. When the suction cup device picks up a heavy object, a rope can be connected to the rope connector 900 and the lifting rod can be connected to the rope so that multiple operators can move it together.

[0060] In some embodiments, the suction cup device can also include a control switch, which can be located on the side of the mounting cavity opposite to the suction cup body 100 for easy operation by the operator. Here, the control switch is not located on the grip lever, so that the operator is less likely to accidentally activate the control switch when gripping the grip lever.

[0061] In this embodiment, the first gripping portion 210 may include two first portions 211, which may be connected to both ends of the second portion 212 respectively, and both first portions 211 may be connected to the first disc body portion 101. The second gripping portion 220 may include two third portions 221, which may be connected to both ends of the fourth portion 222 respectively, and both third portions 221 may be connected to the second disc body portion 102.

[0062] Here, the rope connector 900 can be located between the two first parts 211.

[0063] Optionally, such as Figure 10 , Figure 11 and Figure 14 As shown, the suction cup device may further include a power supply 700, which may be disposed on one side of the grip handle 200 and may be connected to a first portion 211 of the first grip portion 210 and a third portion 221 of the second grip portion 220. The power supply 700 may be used to power the adsorption assembly 600. Specifically, a channel is formed inside the grip rod for a line electrically connected to the power supply 700 to pass through. The channel communicates with the mounting cavity to facilitate the line entering the mounting cavity and electrically connecting to the adsorption assembly 600.

[0064] In some embodiments, the suction cup device may further include a locking component, which may be disposed on the side of the mounting cavity opposite to the suction cup body 100, and the locking component may lock the control switch. This arrangement can prevent accidental activation of the control switch.

[0065] For example, such as Figure 10 , Figure 11 and Figure 13 As shown, a fixing plate 800 can be provided above the mounting cavity. The fixing plate 800 is connected to the first part 211 and the third part 221, and the control switch and locking assembly can be provided on the fixing plate 800.

[0066] 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 plate 800, 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.

[0067] 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 plate 800, 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 plate 800 to restrict the movement of the keycap, thereby locking the control switch. When the sliding part is in the second position, the sliding part avoids the control switch, allowing the control switch to be triggered.

[0068] Of course, the locking component can also be other structures capable of locking the control switch.

[0069] For example, the control switch may include an inhalation control switch and an exhaust control switch, the inhalation control switch being electrically connected to the adsorption assembly 600 and the exhaust control switch being electrically connected to the exhaust valve described below.

[0070] In this embodiment, the locking component may include a first locking component and a second locking component. The first locking component can be used to lock the inhalation control switch to prevent the operator from accidentally touching the inhalation control switch, and the second locking component can be used to lock the venting control switch to prevent the operator from accidentally touching the venting control switch.

[0071] In optional embodiments, such as Figure 2 and Figure 3 As shown, the suction cup body 100 may be provided with at least two vent holes 103, and each adsorption chamber 110 is connected to at least one vent hole 103, that is, at least one vent hole 103 is provided on the cavity wall of each adsorption chamber 110. The suction cup body 100 may also be provided with a vent valve, and the vent hole 103 is 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 chamber 110 by controlling the vent valve, thereby controlling the adsorption and release states of the adsorption chamber 110.

[0072] Optionally, the suction cup body 100 may be equipped with at least two vent valves, each of which can be connected to a corresponding vent hole 103, allowing each vent valve to independently control the pressure of one suction chamber 110. This configuration ensures that each suction chamber 110 has an independent vent hole 103 and vent valve, allowing operators to precisely control the adsorption and release states of each chamber. For example, when handling irregularly shaped objects, only some suction chambers 110 may need to provide adsorption force to fix the object, while other chambers can remain in a released state. By independently controlling the vent valves, the working state of the suction chambers 110 can be flexibly adjusted to meet the adsorption needs of objects of different shapes and sizes, improving operational accuracy and adaptability. Furthermore, in complex adsorption scenarios, the adsorption force can be adjusted in stages according to the object's weight, material, or different stages of the handling process. By controlling the opening and closing times and degrees of different vent valves, staged adsorption and release of the suction chambers 110 can be achieved. For example, when lifting heavy objects, some of the vent valves can be closed first to allow some of the adsorption chambers 110 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.

[0073] In other embodiments, the suction cup body 100 may not be provided with vent holes 103, and each adsorption chamber 110 can be vented through the adsorption assembly 600.

[0074] In some embodiments, the suction cup body 100 is provided with at least two vent holes 103. The suction cup 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 body 100 may be provided with only 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.

[0075] In optional embodiments, such as Figure 3 As shown, the suction cup body 100 may be provided with at least two suction holes 104, each suction hole 104 corresponding to one of the adsorption chambers 110, and each adsorption chamber 110 may be connected to the adsorption assembly 600 through the corresponding suction hole 104. A control valve may also be provided on the suction cup body 100, which may be connected to the suction hole 104 and used to control the connection between the suction hole 104 and the adsorption assembly 600.

[0076] In other embodiments, the suction cup body 100 may not be equipped with a control valve, and the adsorption assembly 600 may simultaneously draw air from each adsorption chamber 110 through the air intake hole 104.

[0077] Optionally, the suction cup device may also include a pressure detection module, which can be used to detect the pressure inside the suction chamber 110. The pressure detection module can be communicatively connected to a control valve, and the control valve opens when the pressure detection module detects that the pressure in the suction chamber 110 is lower than a preset pressure. This setting can automatically adjust the pressure inside the suction chamber 110, preventing the suction effect of the suction cup body 100 from decreasing due to excessively low pressure, thus preventing objects from falling off.

[0078] Of course, the suction cup device may also exclude the pressure detection module.

[0079] Optionally, the suction cup body 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 opening and closing of the corresponding suction port 104 and the adsorption assembly 600. In this embodiment, each adsorption chamber 110 is equipped with an independent suction port 104 and a control valve, enabling the operator to precisely control the adsorption state of each adsorption chamber 110. When handling irregularly shaped objects, only some adsorption chambers 110 may need to provide adsorption force to fix the object. By closing the control valves corresponding to the adsorption chambers 110 that do not need to work, these adsorption chambers 110 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.

[0080] 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 in the corresponding adsorption chamber 110 is less than the preset pressure, the control valve corresponding to the pressure detection element opens.

[0081] During the adsorption process, when the adsorption force of different adsorption chambers 110 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 chamber 110 in real time. When the pressure of some adsorption chambers 110 is less than the preset pressure, it indicates that the adsorption force of the adsorption chamber 110 may be too small or there is an abnormality. At this time, the control valve corresponding to the adsorption chamber 110 opens, which can increase the adsorption force of the adsorption chamber 110. In this way, the adsorption force of each adsorption chamber 110 can be made to be approximately the same, thereby improving the overall adsorption stability of the suction cup device and ensuring that the object is firmly adsorbed.

[0082] 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 chamber 110 according to the actual working conditions, so that the suction cup device can better adapt to various complex situations and ensure the stability of the adsorption effect.

[0083] Of course, the suction cup body 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 adsorption assembly 600. Specifically, each suction port 104 can be connected to the main suction pipeline, which is connected to the adsorption assembly 600, and 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 in the adsorption chamber 110 by detecting the pressure within the main suction pipeline.

[0084] 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 in a part of the adsorption chamber 110 is too high, when the pressure sensing element detects that the pressure in the adsorption chamber 110 is greater than or equal to the critical pressure, the venting valve corresponding to that adsorption chamber 110 opens to release the pressure, thereby preventing the adsorption force from being too large and damaging the object.

[0085] In this embodiment, the pressure detection element can be a pressure sensor, and the adsorption assembly 600 can include a vacuum pump.
