[0033] The following is a detailed description of the specific embodiments of the present invention. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0034] In this utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the orientation in the assembled state. "Inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0035] The existing vacuum suction cup includes a rubber disc 3. To adapt to the irregular surface of the workpiece, the outer thickness of the rubber disc 3 is relatively small, making it easier to contact the workpiece. However, this modification easily allows external air to enter the rubber disc 3, resulting in poor adhesion stability of the rubber disc 3 on rough surfaces.

[0036] On the one hand, the present invention provides an adsorption component, such as Figures 1 to 4 As shown, it includes a support plate 1 and an elastic sealing element 2, the elastic sealing element 2 includes a connecting end face 21 and an adsorption end face 22 arranged opposite to each other, the connecting end face 21 is installed on the first end face 11 of the support plate 1, the connecting end face 21 is used to contact the surface of the workpiece to be transported, and the first end face 11 is provided with a through hole 12 passing through the first end face 11.

[0037] The adsorption assembly described in the present invention is provided with an elastic sealing element 2. The elastic sealing element 2 is deformed when being squeezed, which not only enables the adsorption end face 22 to adapt to the rough surface, but also increases the adsorption area through the adsorption end face 22 in contact with the workpiece surface, thereby preventing air from entering the interior of the vacuum suction cup, thereby increasing the adsorption stability of the suction cup; one problem caused by the addition of the elastic sealing element 2 is the fixation problem between the elastic sealing element 2 and the rubber disc 3. If the elastic sealing element 2 is directly fixed on the rubber disc 3, it will bring about the problem of unchanged replacement and high replacement cost. If the elastic sealing element 2 is detachably fixed on the rubber disc 3, the problems of inconvenient replacement and high replacement cost are solved, but it will bring about the problem of sealing. The sealing problem is that there is a possibility of air leakage between the elastic sealing element 2 and the rubber disc 3, which leads to poor sealing effect and the risk of the workpiece falling off. The utility model provides a support plate 1, on the one hand, to provide an installation position for the elastic sealing element 2; on the other hand, a through hole 12 is provided on the first end face 11 of the support plate 1, so that when the adsorption component is working, the negative pressure inside the suction cup not only acts on the surface of the workpiece, but also acts on the surface of the elastic sealing element 2 through the through hole 12. The greater the negative pressure, the tighter the seal, which not only greatly increases the sealing effect between the elastic sealing element 2 and the support plate 1, thereby improving the adsorption stability of the vacuum suction cup on the rough surface; it also enables the elastic sealing element 2 to be easy to disassemble and replace.

[0038] In the above description, the elastic sealing element 2 is an annular structure having a certain thickness and width. The internal space enclosed by the annular structure serves as the location for generating negative pressure. The annular structure can be connected end to end and can specifically be a circular ring structure, an elliptical ring structure, a polygonal structure, or other annular structure. For ease of installation and manufacturing, the cross-section of the elastic sealing element 2 is rectangular.

[0039] In the above description, the support plate 1 is a plate-shaped annular structure having a certain thickness and a certain width. The annular structure only needs to be connected end to end. Specifically, it can be a circular ring structure, an elliptical ring structure, a polygonal structure, or other annular structures. The support plate 1 is adapted to the shape of the elastic sealing element 2.

[0040] In order to increase the sealing effect between the elastic sealing element 2 and the support plate 1, it is preferred that Figure 1 As shown, the through holes 12 include a plurality of through holes 12, and the plurality of through holes 12 are arranged along the circumference of the support plate 1. Preferably, the plurality of through holes 12 are evenly arranged along the circumference of the support plate 1, so that the elastic sealing element 2 is subjected to uniform circumferential force; and / or

[0041] The distances between the plurality of through holes 12 and the outer periphery of the support plate 1 are not all the same, that is, at least one through hole 12 has a different distance from the outer periphery of the support plate 1 than the other through holes 12. This arrangement facilitates exerting a force on the elastic sealing element 2 in the width direction, further enhancing the sealing effect between the elastic sealing element 2 and the support plate 1. Preferably, the through holes 12 include two groups, a first group of through holes 12 arranged along the circumference of the support plate 1, and a second group of through holes 12 arranged outside the first group of through holes 12, and the second group of through holes 12 arranged along the circumference of the support plate 1. Further preferably, within the two groups of through holes 12, each group of through holes 12 is centrally symmetrically arranged.

[0042] The existing rubber disc 3 suffers from air leakage, partly because the contact area between the rubber disc 3 and the workpiece is too small, allowing gas to enter the rubber disc 3 from the outside. Preferably, the width of the elastic sealing element 2 is greater than or equal to 1.5 times the thickness of the elastic sealing element 2. This configuration not only improves the sealing effect between the elastic sealing element 2 and the workpiece, but also increases the contact area between the elastic sealing element 2 and the support plate 1, further improving the sealing effect between the elastic sealing element 2 and the support plate 1. At the same time, during operation, the elastic sealing element 2 is squeezed inward by atmospheric pressure. This configuration also helps to increase the stability and service life of the elastic sealing element 2.

[0043] Furthermore, in order to prevent the elastic sealing element 2 from being deformed by being squeezed by the atmospheric pressure, Figure 4 As shown, preferably, the support plate 1 includes a first support ring 13, which is arranged on the inner periphery of the support plate 1 and extends in the direction of the elastic sealing element 2. At the same time, when the elastic sealing element 2 is squeezed inward by atmospheric pressure, the inner periphery of the elastic sealing element 2 is tightly connected to the outer periphery of the first support ring 13, further improving the sealing effect between the elastic sealing element 2 and the support plate 1.

[0044] Furthermore, the support plate 1 includes a second support ring 14, which is arranged on the outer periphery of the support plate 1 and extends in the direction of the elastic sealing element 2. This arrangement forms an annular groove for accommodating the elastic sealing element 2 between the first support plate 1 and the second support plate 1, with the elastic sealing element 2 partially installed in the annular groove and partially protruding from the annular groove. Preferably, the elastic sealing element 2 is tightly fitted with the annular groove. When the elastic sealing element 2 is squeezed, the elastic sealing element 2 squeezes the inner periphery, outer periphery, and bottom of the annular groove, further strengthening the sealing effect between the elastic sealing element 2 and the support plate 1.

[0045] In order to connect the support plate 1 with the rubber disc 3 , a connecting ring 15 is provided on the periphery of the support plate 1 . The connecting ring 15 is cylindrical, and one end of the connecting ring 15 is connected to the periphery of the support plate 1 and extends away from the elastic sealing element 2 .

[0046] According to an embodiment of the present invention, the connecting ring 15 can be configured to be integrally provided with the rubber disc 3 .

[0047] According to one embodiment of the present invention, the connecting ring 15 can be configured to be detachably attached to the rubber disc 3. Specifically, the connecting ring 15 is made of an elastic material and is sleeved onto the outer periphery of the rubber disc 3. The connecting ring 15 tightly fits the rubber disc 3 to form a sealed connection. To match the elastic connecting ring 15, the support plate 1 is also made of an elastic material. Preferably, the support plate 1 and the connecting ring 15 are integrally formed.

[0048] In the above description, the elastic sealing element 2 comprises a sealing material having a certain elasticity and being airtight, such as foam plastic, rubber or silicone. There are no special requirements for the material selection of the elastic sealing element 2, and existing elastic sealing materials can be used. Preferably, the elastic sealing element 2 comprises an internally porous foam material.

[0049] Furthermore, in order to increase the deformation of the elastic sealing element 2, an annular through hole 12 is provided inside the elastic sealing element 2 along the circumference of the elastic sealing element 2, that is, the elastic sealing element 2 is a hollow structure.

[0050] After the elastic sealing element 2 is worn, in order to facilitate replacement of the elastic sealing element 2, the elastic sealing element 2 is detachably connected to the support plate 1. Preferably, the elastic sealing element 2 is bonded to the support plate 1.

[0051] Another aspect of the present invention provides a vacuum suction cup, such as Figures 5 to 7 As shown, it includes a glue disc 3 and the adsorption component described in the utility model, and the support plate 1 is sealed and connected to the glue disc 3.

[0052] According to one embodiment of the present invention, the support plate 1 can be configured to be integrally provided with the rubber disc 3;

[0053] According to another embodiment of the present invention, the support plate 1 can be configured to be detachable from the rubber disc 3. In order to connect the support plate 1 to the rubber disc 3, a connecting ring 15 is provided on the outer periphery of the support plate 1. The connecting ring 15 is cylindrical. One end of the connecting ring 15 is connected to the outer periphery of the support plate 1 and extends away from the elastic sealing element 2. The connecting ring 15 is made of elastic material. The connecting ring 15 is sleeved on the outer periphery of the rubber disc 3. The connecting ring 15 is tightly fitted with the rubber disc 3 and is sealed.

[0054] Among the above, Figure 1 As shown, in order to improve the sealing effect between the support plate 1 and the rubber disc 3, a first sealing ring 151 is provided on the inner wall of the end of the connecting ring 15 away from the support plate 1. The first sealing ring 151 protrudes into the interior of the connecting ring 15. Preferably, the first sealing ring 151 is provided integrally with the connecting ring 15.

[0055] In the above, in order to improve the sealing effect between the support plate 1 and the rubber disc 3, as shown in FIG. Figure 7 As shown, a second sealing ring 31 is provided between the rubber disc 3 and the connecting ring 15. Preferably, a sealing ring groove is provided on the outer periphery of the rubber disc 3, and the sealing ring is installed in the sealing ring groove.

[0056] In the above, in order to improve the sealing effect between the support plate 1 and the rubber disc 3, as shown in FIG. Figure 1 As shown, a third sealing ring 152 is provided on the inner wall of one end of the connecting ring 15 close to the support plate 1 , and the third sealing ring 152 protrudes toward the interior of the connecting ring 15 . Preferably, the third sealing ring 152 is provided integrally with the connecting ring 15 .
