Description

Technical Field

[0001] This utility model relates to the field of vacuum adsorption technology, specifically to a suction cup mechanism. Background Technology

[0002] Suction cup mechanisms, as adsorption devices that operate on the principle of negative pressure, have long been widely used in industrial object gripping and light-load support scenarios in daily life. In the industrial field, suction cup mechanisms are mainly used for workpiece gripping; while in daily life, suction cups are mainly used as fasteners to suspend items or as suspended load-bearing components, with their design emphasizing convenience and ease of operation.

[0003] However, when suction cup technology is applied to heavy-duty support applications, such as curtain wall cleaning robots, traditional suction cup mechanisms exhibit numerous limitations. Since traditional suction cups were not originally designed to support heavy-duty robots, their load-bearing capacity cannot be guaranteed. For example, curtain wall cleaning robots need to achieve stable adhesion and movement on vertical or inclined curtain wall surfaces, while also carrying cleaning equipment, water sources, and power supplies, resulting in a significant overall weight. Traditional suction cups cannot guarantee the load-bearing capacity of these components. Utility Model Content

[0022] See Figures 1 to 5 The present invention discloses a suction cup mechanism, including a suction cup body 1 for providing support, wherein the suction cup body 1 is formed of a rigid material; An adsorption element 2 is formed of an elastic material. The adsorption element 2 is at least partially attached to the bottom of the suction cup body 1 to form an adsorption surface 201 of the suction cup mechanism. The adsorption surface 201 is provided with an adsorption hole 202 that penetrates the suction cup body 1. The outer periphery of the adsorption surface 201 is provided with a pressing edge 203 formed of elastic material, and the adsorption surface 201 is provided with a textured structure 2031.

[0023] In use, place the suction surface 201 of the suction cup mechanism on the wall surface, connect the connecting pipe of the vacuum equipment to the suction hole 202, and then turn on the vacuum equipment to evacuate the space between the suction surface 201 and the wall surface. At this time, since the pressing edge 203 is attached to the wall surface, the space inside the pressing edge 203 forms a sealed space during the continuous vacuuming process of the vacuum equipment, so that the suction cup mechanism is attached to the wall surface.

[0024] The adsorption pore 202 in this application can be one or more.

[0025] In this embodiment, a suction cup body 1 made of rigid material is used as a heavy-duty support, while an adsorption element 2 made of elastic material is attached to the bottom of the suction cup body 1 for vacuum adsorption, so as to meet the load-bearing capacity requirements of the suction cup mechanism in the heavy-duty field. Then, with the cooperation of the adsorption element 2 and the pressing edge 203, the vacuum adsorption effect is ensured, thereby ensuring that the suction cup mechanism of this utility model can be used for heavy-duty support, such as in curtain wall cleaning robots.

[0026] It is understood that the rigid materials used in this application include stainless steel, other rigid metals, or rigid metal-plated materials, to ensure that heavy-duty support can be provided. For example, in a curtain wall cleaning robot, a stainless steel suction cup body 1 is preferably used to ensure that the suction cup mechanism can support heavy-duty equipment carrying cleaning devices, water sources, and power supplies.

[0027] In addition, it is understood that the elastic material in this application includes silicone and other materials capable of vacuum adsorption in order to ensure the vacuum adsorption effect.

[0028] As a preferred embodiment of this utility model, such as Figure 3 As shown, the thickness of the pressing edge 203 gradually decreases from the connection point with the adsorption surface 201 to the end, so that the suction cup can gradually adsorb from the thin edge of the pressing edge 203 to the thick edge during the gradual adsorption process, so as to finally stand on the wall surface, thereby improving the wind resistance of the suction cup mechanism and ensuring the adsorption stability of the suction cup, so as to assist the suction cup to stand on the wall surface quickly and ensure the adsorption stability of the suction cup to support heavy-duty equipment.

[0029] Understandably, while a thinner clamping edge 203 facilitates rapid suction, an excessively thin clamping edge 203 can lead to instability, especially during outdoor operations where it may sway in wind, posing a safety risk. Conversely, an excessively thick clamping edge 203 results in unstable suction and potential detachment of the suction cup. This application addresses this by using a clamping edge 203 whose thickness gradually decreases from its connection point with the suction surface 201 to its end. This allows the suction cup to gradually adhere from the thinner edge to the thicker edge during the suction process, ensuring both suction cup stability and support for heavy-duty equipment.

[0030] Furthermore, the thickness of the pressing edge 203 ranges from 1 to 6 mm. The end of the pressing edge 203 away from the adsorption surface 201 has a thickness of about 1 mm, while the end of the pressing edge 203 close to the adsorption surface 201 has a thickness of about 6 mm. This ensures that the pressing edge 203 can adhere to the wall surface to form a sealed space, while also preventing the suction cup from shaking if the pressing edge 203 is too thin.

[0031] Preferably, the included angle between the pressing edge 203 and the adsorption surface 201 is 100°-150°, so that during vacuum adsorption, the pressing edge 203 can gradually adsorb from the outside to the inside, so that the adsorption surface 201 can gradually and completely adhere to the wall surface, thereby allowing the suction cup to stand firmly on the wall surface and thus improving the adsorption stability.

[0032] Taking a curtain wall cleaning robot as an example, the angle between the pressing edge 203 and the adsorption surface 201 is preferably 120°-130°, and the thickness of the pressing edge 203 gradually decreases from the connection point with the adsorption surface 201 to the end, so that the suction cup mechanism can gradually adsorb from the outside to the inside when performing vacuum adsorption. Since the outer edge of the pressing edge 203 is thinner, the adsorption space inside the pressing edge 203 can quickly form a sealed space. As the thickness of the pressing edge 203 gradually increases, it is easier for the adsorption surface 201 to stand firmly on the wall surface quickly, so as to ensure adsorption stability. The thin edge of the pressing edge 203 ensures the adsorption effect, while the gradually transitioning thickness of the pressing edge 203 strengthens the stability of the suction cup mechanism, avoiding the shaking of the equipment caused by the swaying of the suction cup mechanism during the operation of the curtain wall cleaning robot.

[0033] Furthermore, such as Figure 4 As shown, the texture structure 2031 includes multiple square particles 20311 and / or multiple round particles 20312. The square particles 20311 and / or the round particles 20311 are distributed in an array to increase the friction between the wall surface and the adsorption surface 201.

[0034] It is understandable that square particles 20311 can be arrayed on the adsorption surface 201, round particles 20311 can be arrayed on the adsorption surface 201, or both square particles 20311 and round particles 20311 can be arrayed on the adsorption surface 201 at the same time, so as to increase the friction between the wall and the adsorption surface 201.

[0035] Preferred, such as Figure 4 As shown, in one embodiment of this utility model, the texture structure 2031 includes a plurality of square particles 20311 and a plurality of square particles 20311 arranged in an array, wherein round particles 20312 are distributed around the square particles 20311, and square particles 20311 are distributed around the round particles 20312. That is, the square particles 20311 and the round particles 20312 are distributed in a staggered array. By staggering the distribution of two different shapes of anti-slip particles, the friction between the wall surface and the adsorption surface 201 can be further increased.

[0036] Furthermore, the square particle 20311 is a bladed square particle 20311; and / or the round particle 20311 is a bladed round particle 20312.

[0037] It is understandable that the square particles 20311 and round particles 20311 used for anti-slip on the adsorption surface 201 can be sharpened, the square particles 20311 can be sharpened, the round particles 20311 can be sharpened, or both square particles 20311 and round particles 20311 can be sharpened at the same time, so as to further increase the friction between the wall surface and the adsorption surface 201.

[0038] Taking the cleaning of vertical walls by a curtain wall cleaning robot as an example, the "adsorption" of the suction cup mechanism is essentially the result of the positive pressure formed by atmospheric pressure and the surface friction: atmospheric pressure presses the suction cup mechanism against the glass wall, generating sufficient positive pressure, which in turn forms an upward static friction force to resist gravity and keep the suction cup stationary; after the curtain wall cleaning robot has cleaned, the vertical glass wall will inevitably have water stains, which will reduce the friction. Therefore, in order to ensure that the suction cup mechanism does not slide down the vertical glass wall, the above method can be used to increase the friction between the wall and the adsorption surface 201, thus preventing the curtain wall cleaning robot from sliding down.

[0039] Specifically, such as Figure 5 As shown, the adsorption element 2 includes a transition layer 204 and an adsorption layer 205. The transition layer 204 covers the bottom of the suction cup body 1 and wraps around the periphery of the suction cup body 1. The adsorption layer 205 is disposed at the bottom of the transition layer 204 to form the adsorption surface 201, and the pressing edge 203 surrounds the adsorption layer 205.

[0040] In this embodiment, the suction cup body 1 is first wrapped and fixed by the transition layer 204 for transitional fixation, so that the adsorption layer 205 can be placed at the bottom of the transition layer 204 to form the adsorption surface 201.

[0041] The suction cup body 1 and the transition layer 204, and the transition layer 204 and the adsorption layer 205 can be bonded and fixed using adhesive.

[0042] Furthermore, the suction cup body 1 has a step around its periphery, and the transition layer 204 forms a U-shaped groove along its central direction, with the step embedded within the U-shaped groove. In this embodiment, the U-shaped groove and the step that matches it are provided to facilitate the installation and fixation between the transition layer 204 and the suction cup body 1.

[0043] Preferably, the adsorption surface 201 is a planar adsorption surface 201.

[0044] The adsorption element 2 and the pressing edge 203 are preferably made of silicone.

[0045] In summary, the suction cup mechanism of this utility model adopts a suction cup body 1 made of rigid material and an adsorption component 2 made of elastic material. The adsorption component 2 is attached to the bottom of the suction cup body 1 to form the adsorption surface 201 of the suction cup mechanism. In this way, the suction cup body 1 serves as a heavy-duty support, while the adsorption component 2 is used for vacuum adsorption. A pressing edge 203 is provided at the edge of the adsorption surface 201 to ensure the adsorption effect, thereby meeting the load-bearing capacity requirements of the suction cup mechanism in the heavy-duty field and ensuring that the suction cup mechanism can be used for heavy-duty support.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
