[0030] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0031] Unless otherwise defined, the technical terms or scientific terms used in the present invention shall have the usual meanings understood by persons with ordinary skills in the field to which the present invention belongs. The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one" or "one" do not indicate quantity restrictions, but indicate the existence of at least one. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship also changes accordingly.

[0032] The inventors of the present invention have discovered that, firstly, the reason why the vacuum suction cup 200 leaves suction marks on the surface of the adsorbed object 2000 is that when the vacuum suction cup 200 adsorbs the adsorbed object 2000, only the center of the vacuum suction cup 200 and the edge of the vacuum suction cup 200 are pressed tightly against the adsorbed object 2000 by the adsorption force, and the adsorption force is too concentrated in the middle of the suction cup 200, which easily leaves the center suction marks and edge suction marks of the vacuum suction cup 200 on the adsorbed object 2000.

[0033] Secondly, the current vacuum suction cup 200 is made of silicone / rubber, which easily adheres to dust and dirt and easily brings the dirt to the adsorbed object 2000. In addition, during use, these materials themselves are easy to fall off and have a large friction with the adsorbed object 2000. Frequent adsorption and friction forces will increase the risk of wear and fall off, thereby leaving material on the adsorbed object. Frequent replacement of the vacuum suction cup 200 is very cost-effective.

[0034] Based on the above findings, the inventors have proposed a vacuum suction cup pad 100 , which can be used on a vacuum suction cup 200 to effectively overcome the above problems.

[0035] Hereinafter, the vacuum suction cup pad 100 according to an embodiment of the present invention will be described first.

[0036] Figure 1 An alternative embodiment of a vacuum cup pad 100 according to the present invention is shown.

[0037] like Figure 1 As shown, the vacuum suction cup pad 100 according to the present invention includes: a breathable adsorption portion 110 , and the breathable adsorption portion 110 is used to cover the surface of the vacuum suction cup 200 .

[0038] In other words, the vacuum suction cup 200 adsorbs the adsorbed object 2000 through the breathable adsorption portion 110. Since the entire surface of the breathable adsorption portion 110 is breathable and in contact with the adsorbed object 2000 on the entire surface, the adsorption force is distributed more evenly, thereby achieving traceless adsorption and preventing the adsorption force of the vacuum suction cup 200 from being concentrated in the middle of the vacuum suction cup 200, which would cause excessive force on the local part of the adsorbed object 2000 and easily cause the risk of the adsorbed object 2000 breaking.

[0039] Furthermore, the vacuum suction cup pad 100 further includes a sleeve portion 120 , which is formed in a cylindrical shape and one end of which is connected to an edge of the breathable adsorption portion 110 .

[0040] For example, the sleeve portion 120 and the breathable adsorption portion 110 are integrally formed, and the breathable adsorption material is formed into a shape (circular, square, etc.) larger than the area of ​​the vacuum suction cup 200, wherein the portion for contacting the bottom surface of the vacuum suction cup 200 is the breathable adsorption portion 110, and the portion for wrapping around the vacuum suction cup 200 is the sleeve portion 120.

[0041] Furthermore, a closing portion 130 is provided at the other end of the sleeve portion 120 , and an elastic rubber ring or a drawable rope is provided inside the closing portion 130 .

[0042] In other words, the other end of the sleeve is closed by an elastic rubber ring or a drawable drawstring (for example, by tightening and knotting the drawable drawstring).

[0043] During use, the sleeve portion 120 wraps around the vacuum suction cup 200, and the closing portion 130 can make the vacuum suction cup pad 100 contact the suction cup closely and is not easy to fall off even in a non-working state (ie, a vacuum state).

[0044] When the vacuum suction cup pad 100 needs to be replaced, the closing portion 130 can be opened (pull open the elastic rubber ring or loosen the drawstring), the vacuum suction cup pad 100 can be removed from the surface of the vacuum suction cup 200, and then replaced with a new vacuum suction cup pad 100, which can achieve convenient replacement, and the cost of the vacuum suction cup pad 100 is relatively low, which can save costs.

[0045] According to some other embodiments of the present invention, a bonding layer is provided on one side surface of the breathable adsorbent portion 110 along the edge of the breathable adsorbent portion 110 , and a release film is provided on the bonding layer.

[0046] That is, the edge of the air-permeable adsorption part 110 is provided with an adhesive layer with a release film, and during use, the release film is torn off, and the adhesive layer is attached to the vacuum suction cup 200, and the air-permeable adsorption part 110 is tightly combined with the vacuum suction cup 200 through the adhesion of the adhesive layer. In this way, a simple and convenient structure can be achieved.

[0047] According to some embodiments of the present invention, the breathable adsorbent portion 110 is formed with one or more through holes.

[0048] like Figure 2 As shown, the air-permeable adsorbent portion 110A is formed with one through hole, and the air-permeable adsorbent portion 110B is formed with a plurality of through holes (eg, ten).

[0049] The through holes can increase the air permeability, thereby increasing the adsorption strength, so that the vacuum suction cup pad 100 adsorbs the adsorbed object 2000 more firmly, and can meet the use requirements of some adsorbed objects 2000 with higher adsorption strength requirements (such as heavier adsorbed objects 2000).

[0050] Furthermore, the breathable adsorbent portion 110 is formed with a plurality of through holes, and the plurality of through holes are evenly distributed in the breathable adsorbent portion 110 .

[0051] That is, the air-permeable adsorbent portion 110 is formed with a plurality of through holes evenly distributed in the air-permeable adsorbent portion 110. Thus, during use, the adsorption force can be evenly distributed and the adsorption strength can be increased.

[0052] According to some embodiments of the present invention, at least the air permeable adsorption portion 110 of the vacuum suction cup pad 100 is formed of a fiber material.

[0053] That is, the air-permeable adsorption part 110 of the vacuum suction cup pad 100 is formed of a fiber material, or the air-permeable adsorption part 110 and the sleeve part 120 are both formed of a fiber material.

[0054] The fiber material has good air permeability, which can make the adsorption force evenly distributed. The vacuum suction cup pad 100 using this material can adsorb the adsorbed object 2000 very well. The fiber material has good softness, which can avoid leaving suction marks on the surface of the adsorbed object. The fiber material can be processed into a dust-free material (such as a dust-free cloth, etc.), which is not easy to adhere to dust, and can avoid leaving dust on the adsorbed object 2000. At the same time, the friction between the fiber material and the adsorbed object 2000 is relatively small, and the fiber material itself is not easy to fall off. The fiber material will not fall off when it comes into contact with the adsorbed object 2000, avoiding the risk of leaving the material itself on the adsorbed object 2000.

[0055] Furthermore, the fiber material may include one or more of the following: non-woven fabric, fiber paper, knitted fabric, and the like.

[0056] According to some embodiments of the present invention, the breathable adsorbent part 110 includes: a base layer; and a hydrophobic and oleophobic layer formed on the surface of the base layer.

[0057] That is, the air-permeable adsorbent part 110 includes a base layer having a hydrophobic and oleophobic layer formed on its surface.

[0058] Due to the hydrophobic and oleophobic properties of the base layer (such as a nanolayer, etc.), no moisture or oil will remain on the surface during use, making the breathable adsorption portion 110 cleaner. The adsorbed object 2000 is adsorbed through the base layer, and it is less likely to leave suction marks on the surface of the adsorbed object 2000, thereby enhancing the dust-free adsorption effect and being able to be used in high humidity and oily environments.

[0059] In addition, an embodiment of the present invention further provides a vacuum adsorption device 1000 , including: a vacuum suction cup 200 and a vacuum suction cup pad 100 .

[0060] The vacuum suction cup pad 100 is any one of the vacuum suction cup pads 100 mentioned above.

[0061] For example, Figure 3 As shown, the vacuum suction device 1000 includes a vacuum suction cup 200, a vacuum suction cup pad 100 and a joint 300, one end of the joint 300 is used to connect to the suction pipe, and the other end of the joint 300 is connected to the vacuum suction cup 200, and the surface of the vacuum suction cup 200 wraps the vacuum suction cup pad 100.

[0062] like Figure 4 As shown, during use, the vacuum adsorption device 1000 adsorbs the adsorbed object 2000 (such as a glass component), thereby achieving dust-free adsorption, which can improve the yield of the adsorbed object 2000 and save costs.

[0063] Through the experiment comparison, the experimental group (the vacuum adsorption device 1000 with the vacuum suction cup pad 100 of the present invention) and the reference group (the vacuum adsorption device commonly used in the production line is directly used, that is, the vacuum suction cup pad 100 is not set), each adsorbed and transferred 50 pieces of mobile phone cover glass, and observed whether there were suction marks under steam conditions. The results are shown in Table 1.

[0066] It is found through experiments that the vacuum adsorption device 1000 of the present invention has obvious effects and can achieve traceless adsorption without leaving any suction marks on the surface of the adsorbed object 2000.

[0067] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
