The "one", "a" or "the" and similar words used in the utility model patent application description and claims do not represent quantity limitation, but indicate that there is at least one; The "first", "second" and "third" used in this document should not be regarded as the limitation of the order of components, but only as a distinction between different components; "Include" or "contain" and similar words indicate that the elements or objects appearing before "include" or "contain" cover the elements or objects listed after "include" or "contain" and their equivalents, but do not exclude other elements or objects with the same function.
[0036] In order to more clearly describe the specific structure and composition of the sponge sucker, the accompanying drawings are combined Figures 1-3 This embodiment is described:
[0037] As Figure 1As shown, a sponge suction cup comprises a suction cup base 1, the suction cup base 1 has a vacuum cavity 101, an interface end 102 and a suction end 103, the suction end 103 is provided with a central suction hole 104 communicating with the vacuum cavity 101 and an annular support 2 extending outwardly outside the central suction hole 104; the outer side of the annular support 2 is sleeved with a sponge ring 3 which is axially compressible, the axial length of the sponge ring 3 is greater than that of the annular support 2; the sponge ring 3 comprises a sponge body 301 and a dense layer 302 fixed on one side end face of the sponge body 301; the outer side end face of the suction end 103 is provided with an annular abutting surface 4 corresponding to the region of the dense layer 302, the annular abutting surface 4 is provided with sponge suction holes 5 communicating with the vacuum cavity 101 and capable of adsorbing the dense layer 302 when the vacuum cavity 101 is under negative pressure.
[0038] The interface end 102 is connected with an external negative pressure pipeline, when entering the adsorption state, the pressure in the vacuum cavity 101 is reduced through the interface end 102, after one end of the sponge body 301 without the dense layer 302 is attached to the surface of the product, the airflow in the vacuum cavity 101, the central suction hole 104, the annular support 2 and the sponge body 301 is extracted, thereby adsorbing and grabbing the product, the sponge body 301 is slightly compressed in the axial direction to adapt to the uneven surface of the product.
[0039] The sponge ring 3 is sleeved on the annular support 2, which can prevent the sponge ring 3 from falling off in the non-adsorption state, facilitate the installation and replacement of the sponge ring, when entering the adsorption state, the internal pressure of the sponge suction holes 5 communicating with the vacuum cavity 101 is also reduced, thereby extracting the air between the annular abutting surface 4 and the dense layer 302 and continuously keeping them attached during the adsorption and grabbing process, so that the suction cup can adsorb the sponge ring 3 while adsorbing the product by taking advantage of the characteristic of the sponge suction cup that can be vacuumized, ensuring the air tightness of the abutting position of the sponge ring 3 and the suction cup base 1 and the stability of the sponge ring 3 when adsorbing the product, without the need for bonding and glue residue.
[0040] Referring to Figure 1 and Figure 2 , the annular support 2 can also play a positioning effect on the sponge ring 3 and avoid serious deformation caused by excessive contraction of the sponge ring 3, thereby prolonging the service life; when replacing, the old sponge ring 3 is directly pulled out and a new sponge ring 3 is sleeved on the annular support 2, and when installing the sponge ring 3, it is necessary to ensure that the dense layer 302 is in contact with the annular abutting surface 4 in place;
[0041] A non-slip pattern 201 can be provided on the outer circular surface of the annular support 2 close to the suction cup base 1, which provides a small amount of friction to prevent the sponge ring 3 from sliding off the annular support 2 at will in the non-adsorption state, and the non-slip pattern 201 is designed on the end close to the suction cup base 1, the deformation amount and displacement amount of the sponge ring 3 at this end are small, which does not interfere with the deformation and recovery of the sponge ring 3;
[0042] The assembly slope 202 is arranged on the outer circumferential surface of the annular support 2 away from the suction cup base 1, which facilitates the sponge ring 3 to be sleeved on the annular support 2 from the end.
[0043] Referring to Figure 3 , the sponge ring 3 and the annular support 2 have a difference in axial length, and the difference is greater than the compression length of the sponge ring 3 when the product is adsorbed. The sponge body 301 can be polyurethane sponge, silica gel sponge and EPDM rubber foamed sponge, which can bear higher load and has good elasticity and thermal stability; the dense layer 302 is beneficial to the stable adhesion of the sponge ring 3 and the suction cup base 1, and reduces the external airflow entering the sponge adsorption hole 5. When the dense layer 302 is processed, it is preferred that the air permeability of the dense layer 302 is much smaller than that of the sponge body 301. Specifically, the impregnation technology or the plastic impregnation technology can be used to form the dense layer 302 at one end of the sponge body 301.
[0044] Referring to Figure 1 To ensure the uniformity and stability of the sponge ring 3 adsorption, the designed sponge adsorption hole 5 is not less than three, and is a circular hole and is distributed at equal angles around the annular support 2; the one-way valve 6 is arranged in the suction cup base 1 and communicates the vacuum cavity 101 and the sponge adsorption hole 5, so that the airflow between the annular abutting surface 4 and the dense layer 302 can only enter the vacuum cavity 101 from outside to inside in one direction, thereby improving the stability of the adsorption.
[0045] Referring to Figure 1 , the annular protrusion 7 is arranged on the outer side surface of the adsorption end 103, so that the annular abutting surface 4 is recessed between the annular protrusion 7 and the annular support 2; after the dense layer 302 contacts the annular abutting surface 4, the sponge ring 3 extends to between the annular protrusion 7 and the annular support 2, and the air tightness is better.
[0046] Referring to Figure 2 , the detachable filter 8 is arranged in the central suction hole 104 of the suction cup base 1, so as to avoid large particles of dust from entering the negative pressure pipeline through the suction cup base 1.
[0047] The parts not described in the above embodiments are prior art.
[0048] It should be noted that although the utility model has been described through the above embodiments, the utility model can also have other various embodiments. Those skilled in the art can obviously make various corresponding changes and modifications to the utility model without departing from the spirit and scope of the utility model, but these changes and modifications should all belong to the scope protected by the claims and equivalents of the utility model.
