[0032] Figure 1 1 is a schematic structural diagram of a suction cup 100 according to an embodiment of the present invention when a sealing member 20 is not provided. Figure 2 is a schematic position diagram of a sealing member 20 and an expansion portion 11 according to an embodiment of the present utility model. Figure 2 Where D is the thickness of the seal 20. Figure 1 and Figure 2 As shown, a suction cup 100 for conveying a sheet material comprises a suction cup body 10 and a sealing member 20. The suction cup body 10 has an extension portion 11 extending obliquely outward. The sealing member 20 is disposed at the end of the extension portion 11 and is connected to the extension portion 11. The sealing member 20 is configured to at least partially enter the deep grooves of the deep-grained panel 200 when the suction cup 100 adsorbs the deep-grained panel 200, so as to form a vacuum seal between the suction cup 100 and the deep-grained panel 200. Here, it can be understood that the edge of the bottom of the suction cup body 10 extends obliquely outward to form the extension portion 11, the extension portion 11 is elastic, and the bottom surface of the end of the extension portion 11 is flush with the plane of the sheet material, so as to facilitate the suction cup 100 to form a seal with the sheet material.

[0033] When the suction cup 100 adsorbs the deep-patterned panel 200, since the surface of the deep-patterned panel 200 has concave deep patterns, a sealing member 20 is provided to be connected to the end of the inclined extension portion 11. After the suction cup 100 contacts the deep-patterned panel 200, the suction cup 100 is evacuated and the sealing portion at the end of the extension portion 11 enters into the deep patterns, thereby forming a seal between the suction cup 100 and the deep-patterned panel 200. The suction cup 100 can adsorb the deep-patterned panel 200 under vacuum negative pressure, thereby sucking up the deep-patterned panel 200.

[0034] This embodiment provides a seal 20 at the end of an extension portion 11 extending outward from the suction cup body 10, and at least a portion of the seal 20 enters into the deep grooves of the deep-grained panel 200 when the suction cup 100 adsorbs the deep-grained panel 200. This not only ensures that a vacuum can be established between the suction cup 100 and the deep-grained panel 200, so that the suction cup 100 can suck up the deep-grained panel 200, but also improves the sealing between the suction cup 100 and the deep-grained panel 200, thereby improving the adsorption capacity of the suction cup 100.

[0035] The suction cup 100 of the utility model can also be used to adsorb general plates with smooth surfaces. When the suction cup 100 adsorbs the plates with smooth surfaces, after the suction cup 100 contacts the surface of the plates, the suction cup 100 is vacuumed, and the inclined surface on the inner side of the extension portion 11 gradually adheres to the surface of the deep-patterned panel 200, so that a vacuum seal is formed between the suction cup 100 and the plates. The suction cup 100 can adsorb the plates under vacuum negative pressure, thereby sucking up the plates.

[0036] In one embodiment, the seal 20 is made of a foam material, and the seal 20 is set on the inner side of the extension part 11 by pasting. Specifically, the seal 20 is made in the form of a foam board, the foam board has a certain thickness D, and is connected to the inner side of the extension part 11 by pasting. Here, when the seal 20 is pasted on the inner side of the extension part 11, the height of the seal 20 protruding relative to the inclined surface on the inner side of the extension part 11 is the thickness D of the seal 20. The foam material has the advantages of light weight, high strength and elasticity, good durability, and easy processing. The seal 20 made of foam material has excellent bonding properties, can effectively form a bond with the extension part 11, ensure the stability and durability of the connection between the seal 20 and the extension part 11, and then ensure the sealing and stability of the suction cup 100 adsorbing the plate.

[0037] The sealing member 20 made of foam material can fill the gap between the end of the extension part 11 and the deep-grained panel 200 during the suction process of the suction cup 100, so as to achieve a close fit between the suction cup 100 and the deep-grained panel 200, effectively prevent air leakage, and achieve a stable vacuum seal. The sealing member 20 can also adjust the foaming amount and hardness according to actual needs during the pasting process to meet the pasting requirements of the sealing member 20 and achieve the best pasting effect.

[0038] When the suction cup 100 adsorbs the deep-grained panel 200, the suction cup 100 and the deep-grained panel 200 are in contact and vacuum is drawn, generating pressure to adsorb the deep-grained panel 200. The sealing member 20 made of the foam material is relatively soft and can enter the deep grain of the deep-grained panel 200 under negative pressure, so that the edge of the suction cup 100 forms a seal with the deep-grained panel 200, so that a vacuum seal is formed between the deep-grained panel 200 and the suction cup 100, thereby sucking up the deep-grained panel 200.

[0039] In this embodiment, the bottom surface of the seal 20 is flush with the bottom surface of the extension 11. Here, when the suction cup 100 adsorbs the deep-grained panel 200, an adsorption surface is formed between the suction cup body 10 and the deep-grained panel 200, the bottom surface of the end of the extension 11 is parallel to the adsorption surface, and the bottom surface of the seal 20 is flush with the bottom surface of the extension 11. Specifically, when the suction cup 100 adsorbs the deep-grained panel 200, the bottom surface of the seal 20 is flush with the bottom surface of the extension 11, which is conducive to the alignment and contact of the seal 20 with the deep-grained panel 200, ensuring that the suction cup 100 is aligned with the deep-grained panel 200 in all directions, and facilitating the seal 20 to enter the deep grain of the deep-grained panel 200, so that a vacuum seal is formed between the suction cup 100 and the deep-grained panel 200.

[0040] In this embodiment, the thickness of the seal 20 is any value in the range of 2.0 mm to 5.0 mm, for example, it can be set to 2.0 mm, 3.0 mm, 4.0 mm, 5.0 mm. In this embodiment, the thickness of the seal 20 is set to 3.0 mm. In other embodiments, the thickness of the seal 20 can be set according to actual needs. When the deep groove height of the deep-grained panel 200 is small, a seal 20 of smaller thickness can be set to save costs; when the deep groove height of the deep-grained panel 200 is large, a seal 20 of larger thickness can be set so that the seal 20 can enter the bottom of the deep groove, ensuring that a vacuum seal is formed between the deep-grained panel 200 and the suction cup 100, so that the suction cup 100 can suck up the deep-grained panel 200.

[0041] Figure 3 FIG. 2 is a schematic position diagram of a sealing member 20 and an extension portion 11 according to another embodiment of the present invention. Figure 3 As shown, in another embodiment, the seal 20 is made of silicone material, and the seal 20 is sleeved on the end of the extension part 11. Here, the seal 20 is set in the form of a silicone sleeve, and the seal 20 covers the end of the extension part 11. The seal 20 made of silicone material is soft in texture and has good elasticity and aging resistance. When the suction cup 100 forms a vacuum, the soft silicone seal 20 can be squeezed into the deep grooves of the deep-grained panel 200 under the negative pressure of the vacuum, so that a vacuum seal is formed between the deep-grained panel 200 and the suction cup 100, so that the suction cup 100 can suck up the deep-grained panel 200.

[0042] In this embodiment, the bottom surface of the seal 20 is a plane. The bottom surface of the seal 20 made of silicone material is set to a plane, and when the suction cup 100 absorbs the deep-grained panel 200, the plane is flush with the surface of the deep-grained panel 200, which is conducive to the seal 20 and the deep-grained panel 200 being aligned and contacted, ensuring that the suction cup 100 is aligned and contacted with the deep-grained panel 200 in all directions, and facilitating the seal 20 to enter the deep grooves of the deep-grained panel 200, so that a vacuum seal is formed between the suction cup 100 and the deep-grained panel 200, so that the suction cup 100 can suck up the deep-grained panel 200.

[0043] Figure 4 FIG. 2 is a schematic position diagram of a sealing member 20 and an expansion portion 11 according to another embodiment of the present invention. Figure 4As shown, in another embodiment, the cross section of the seal 20 is semicircular and is disposed on the inner side of the extension portion 11, and the bottom of the seal 20 protrudes from the bottom of the extension portion 11. Here, the seal 20 is hemispherical and is located on the inner side of the extension portion 11. The hemispherical flange is soft in texture and can be easily squeezed into the bottom of the deep grooves of the deep-grained panel 200, which is conducive to the vacuum seal between the suction cup 100 and the deep-grained panel 200, so that the suction cup 100 can suck up the deep-grained panel 200.

[0044] In this embodiment, the seal 20 is integrally formed with the extension 11. Specifically, when manufacturing the suction cup 100, the end of the extension 11 is thickened to form a hemispherical shape protruding toward the inside of the extension 11, so that the cross section of the seal 20 is semicircular. The seal 20 is integrally formed with the extension 11, which has better connectivity than the solution in which the seal 20 is pasted or sleeved on the end of the extension 11, improves the stability of the suction cup 100 structure, and is conducive to improving the stability of the suction cup 100 adsorbing the deep-grained panel 200.

[0045] Figure 5 FIG. 1 is a schematic top view of a suction cup 100 according to an embodiment of the present invention. Figure 5 As shown, in this embodiment, the suction cup body 10 further includes a frame 30, and the suction cup body 10 is sleeved on the frame 30. The frame 30 is provided with a plurality of vents 31, so as to draw a vacuum through the vents 31, thereby adsorbing the deep-veined panel 200. Specifically, when the suction cup 100 is vacuumed, the top of the frame 30 is connected to the vacuum device, and the air between the suction cup 100 and the deep-veined panel 200 is drawn through the vents 31 on the frame 30, so that a vacuum seal is formed between the suction cup 100 and the deep-veined panel 200, so that the suction cup 100 can suck up the deep-veined panel 200.

[0046] In this embodiment, the number of vents 31 is five, one of which is located at the center of the skeleton 30, and the remaining four vents 31 are evenly arranged on the skeleton 30. Specifically, the skeleton 30 is circular, and the number of vents 31 is set to five, one of which is located at the center of the skeleton 30, and the remaining four are evenly arranged along the circumference of the skeleton 30, which is conducive to uniform vacuuming, ensuring that the expansion part 11 and the seal 20 in all directions are subjected to uniform negative pressure, improving the endurance of the suction cup 100 and the stability of the suction of the suction cup 100. The bottom surface of the skeleton 30 is also provided with multiple groups of annular air ducts, which are conducive to evenly extracting the air between the suction cup 100 and the deep-grained panel 200, further improving the durability of the suction cup 100 and the stability of the suction of the suction cup 100.
