Description

Technical Field

[0001] This utility model belongs to the field of suction device technology, specifically relating to a vacuum suction cup and suction device. Background Technology

[0002] Vacuum suction cups are common suction and gripping structural components in industrial production, widely used in material gripping, transferring, or handling equipment. Vacuum suction cups utilize vacuum to grip materials, preventing them from separating from the suction cup and facilitating subsequent handling or transfer, thus promoting automation and intelligent material handling. For example, in machining processes, processed parts need to be transferred to a transfer area. Vacuum suction cups in handling equipment can be used to grip the parts, creating a vacuum that firmly holds them to the suction cup. Then, robotic arms on the handling equipment can move the parts. Vacuum suction cups can handle a wide variety of materials, such as sheet materials, packaging bags or boxes, and irregularly shaped parts. Different types of suction cups can be selected depending on the type of material being gripped. During production, materials need to be continuously moved on the production line. In some material handling processes, due to the large surface area of ​​the material, after a suction cup picks up one piece, the material can easily clog the air vents on the suction cup, making it difficult for the suction cup to continue gripping. This results in only one piece of material being gripped at a time, preventing the simultaneous gripping of multiple pieces and leading to low efficiency. Utility Model Content

[0003] The purpose of this utility model embodiment is to provide a vacuum suction cup and suction device to solve the problem that the suction cup cannot pick up multiple materials at the same time.

[0004] In a first aspect, this utility model embodiment provides a vacuum suction cup, comprising:

[0005] The suction cup body has a first chamber, a second chamber with an opening, and a third chamber on the outer periphery of the second chamber. The third chamber extends around the outer periphery of the side wall and the outer periphery of the bottom wall of the second chamber, and the first chamber communicates with the third chamber.

[0006] The bottom wall of the second chamber is provided with a plurality of first through holes, and the side wall of the second chamber is provided with a plurality of second through holes. The first through holes connect the second chamber to the third chamber, and the second through holes connect the second chamber to the third chamber.

[0007] Furthermore, a third through hole is provided on the side wall of the first chamber near the bottom wall of the second chamber, and the third through hole connects the first chamber and the third chamber.

[0008] Furthermore, there are multiple first through holes, which are evenly spaced along the bottom wall of the second chamber.

[0009] Furthermore, there are multiple second through holes, which are evenly spaced along the sidewall of the second chamber.

[0010] Furthermore, the opening edge of the second chamber is provided with a groove, which extends through the thickness direction of the side wall of the second chamber.

[0011] Furthermore, there are multiple grooves, which are circumferentially spaced along the opening edge of the second chamber.

[0012] Furthermore, the suction cup also includes:

[0013] The vacuum tube has a suction hole on its suction cup body, which is connected to the first chamber, and one end of the vacuum tube is connected to the suction hole.

[0014] Furthermore, the suction cup also includes:

[0015] A rotating plate is disposed on the bottom wall of the second chamber, which is cylindrical. The rotating plate is rotatable on the bottom wall of the second chamber. A first through hole is provided on the rotating plate at a position corresponding to the first through hole.

[0016] Furthermore, the suction cup also includes:

[0017] A rotating cylinder is disposed on the side wall of the second chamber, which is cylindrical. The rotating cylinder is rotatable on the side wall of the second chamber, and a second through hole is provided on the rotating cylinder at a position corresponding to the second through hole.

[0018] Secondly, this utility model embodiment provides a suction device, including:

[0019] The suction cup described in the above embodiments.

[0020] This invention relates to a vacuum suction cup, wherein the suction cup body has a first chamber, a second chamber with an opening, and a third chamber extending around the outer periphery of the side wall and bottom wall of the second chamber. The first chamber and the third chamber are connected. The bottom wall of the second chamber has multiple first through holes, and the side wall of the second chamber has multiple second through holes. The first through holes connect the second chamber and the third chamber, and the second through holes also connect the second chamber and the third chamber. During use, a vacuum is created in the first chamber to achieve a certain degree of vacuum in the second and third chambers for suction. When suctioning materials, such as sheet materials, the large surface area of ​​the material can cause it to block the first through holes on the bottom wall of the second chamber when a piece of material is suctioned into it. However, the material can continue to be suctioned through the second through holes on the side wall of the second chamber, allowing the materials to be stacked within the second chamber. This enables multiple pieces of material to be simultaneously and stacked for suction, improving the efficiency of material suction and handling. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0033] The terms "first," "second," etc., used in the specification and claims of this utility model are used to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this utility model can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0034] like Figures 1 to 5 As shown, the vacuum suction cup of this utility model embodiment includes:

[0035] The suction cup body 10 can be cylindrical or cuboid. The suction cup body 10 has a first chamber 11 and a second chamber 12 with an opening. The inner edge of the opening of the second chamber 12 can be an arc-shaped curved surface to facilitate material entry into the second chamber. A third chamber 13 can be provided around the outer periphery of the second chamber 12. The third chamber 13 can extend around the outer periphery of the sidewall and bottom wall of the second chamber 12, and can surround the second chamber 12. The first chamber 11 and the third chamber 13 are in communication.

[0036] The bottom wall of the second chamber 12 may be provided with multiple first through holes 21, which may be spaced apart. The side wall of the second chamber 12 is provided with multiple second through holes 22, which may be spaced apart. The first through holes 21 may connect the second chamber 12 and the third chamber 13, and the second through holes 22 may connect the second chamber 12 and the third chamber 13. During the process of evacuating the first chamber 11 through the vacuum tube, the third chamber 13 may have a vacuum. At the same time, a vacuum may be formed in the second chamber 12 through the first through holes 21 and the second through holes 22. Materials may be sucked up through the opening of the second chamber 12. For example, sheet-like materials, such as sheet-like packaging bags or boxes, may be sucked up through the opening of the second chamber 12.

[0037] The suction cup body 10 can be a one-piece structure. Alternatively, the suction cup body 10 can be a separate structure, comprising a first suction cup body and a second suction cup body, which are detachable. Figure 3As shown, the first suction cup body has a first chamber 11, and the second suction cup body has a second chamber 12 with an opening. A third chamber 13 may be provided on the outer periphery of the second chamber 12 on the second suction cup body. The third chamber 13 extends around the outer periphery of the side wall and the outer periphery of the bottom wall of the second chamber 12. The third chamber 13 may surround the second chamber 12. A third through hole may be provided on the side wall of the third chamber 13 near the first chamber 11. The first chamber 11 may be located directly below the third chamber 13. The first chamber 11 and the third chamber 13 may be connected through the third through hole.

[0038] In the vacuum suction cup of this embodiment, the third chamber extends around the outer periphery of the second chamber. A first through-hole on the bottom wall of the second chamber connects the second chamber to the third chamber, and a second through-hole on the side wall of the second chamber connects the second chamber to the third chamber. During use, a vacuum is created in the first chamber to achieve a certain degree of vacuum in the third and second chambers for suction. When suctioning materials, such as sheet materials, the large surface area of ​​the material can cause it to block the first through-hole when it is sucked into the second chamber and contacts the bottom wall. However, the material can continue to be sucked through the second through-hole on the side wall of the second chamber, allowing the materials to be stacked within the second chamber. This enables multiple materials to be simultaneously and stacked, improving the efficiency of material suction and handling.

[0039] In some embodiments, a third through hole 23 is provided on the side wall of the first chamber 11 near the bottom wall of the second chamber 12. The number of third through holes 23 can be one or more. The third through hole 23 connects the first chamber 11 and the third chamber 13. Thus, during the process of drawing a vacuum from the first chamber 11 through the vacuum tube, the third chamber 13 can have a vacuum degree. A vacuum degree can be formed in the second chamber 12 through the first through hole 21 and the second through hole 22 to facilitate the suction of materials.

[0040] Optionally, there can be multiple first through holes 21, which are evenly spaced along the bottom wall of the second chamber 12. The multiple first through holes 21 can be arranged in an array on the bottom wall of the second chamber 12, and the first through holes 21 can be circular, elongated, elliptical, etc. The bottom wall of the second chamber 12 can have different regions; for example, it can have a central region and an edge region, with the edge region surrounding the central region. The distribution density of the first through holes 21 in the central region can be different from that in the edge region; for example, the distribution density of the first through holes 21 in the central region is less than that in the edge region.

[0041] Optionally, there may be multiple second through holes 22, which are evenly spaced along the sidewall of the second chamber 12. The multiple second through holes 22 can be arranged in multiple rows and columns on the sidewall of the second chamber 12, and can be circular, elongated, elliptical, etc. Elongated holes can extend along the depth of the second chamber, allowing for the simultaneous suction of multiple layers of material in a stacked manner after suctioning one layer of material.

[0042] In some embodiments, the opening edge of the second chamber 12 may be provided with a groove 30, which may extend through the thickness direction of the side wall of the second chamber 12. When the suction cup picks up the material on the flat table, the groove 30 can prevent the edge of the suction cup from sticking to the table, thus facilitating the movement of the suction cup.

[0043] Optionally, there can be multiple grooves 30, which are circumferentially spaced along the opening edge of the second chamber 12. The multiple grooves 30 can be evenly spaced along the opening edge of the second chamber 12.

[0044] Optionally, the suction cup may also include:

[0045] The vacuum tube 40 and the suction cup body 10 are provided with suction holes. The suction holes are connected to the first chamber 11. One end of the vacuum tube 40 is connected to the suction holes. The vacuum tube 40 can be connected to a vacuum device so as to form a vacuum in the first chamber 11.

[0046] Optionally, the suction cup may also include:

[0047] The gripping part 70 can be provided on the suction cup body 10. The gripping part 70 can be connected to the suction cup body 10 by bolts, which makes it easy to disassemble.

[0048] In some embodiments, such as Figure 4 As shown, the suction cup may also include:

[0049] A rotating plate 50 is provided, which can be disposed on the bottom wall of the second chamber 12. The rotating plate 50 can be disassembled as needed. The second chamber 12 can be cylindrical. The rotating plate 50 can rotate on the bottom wall of the second chamber 12. A first through hole 51 is provided on the rotating plate 50 at a position corresponding to the first through hole 21. A rotating shaft can be provided at the center of the rotating plate 50, and a rotating hole can be provided at the center of the bottom wall of the second chamber 12. The rotating shaft can be disposed in the rotating hole, so that the rotating plate 50 can rotate. The first through hole 51 is provided on the rotating plate 50 at a position corresponding to the first through hole 21. The size and shape of the first through hole 51 and the corresponding first through hole 21 can be exactly the same. During the rotation of the rotating plate 50, the first through hole 51 and the corresponding first through hole 21 may be misaligned. For example, when the rotating plate 50 is not rotating, the first through hole 51 and the corresponding first through hole 21 completely overlap, and the first through hole 51 and the corresponding first through hole 21 are connected. During the rotation of the rotating plate 50, the first through hole and the corresponding first through hole 21 partially overlap. The overlapping part of the first through hole 21 can conduct gas to form a vacuum. A vacuum can be formed through this position to suck up materials. During the rotation of the rotating plate 50, the position and size of the overlap between the first through hole 51 and the corresponding first through hole 21 can be changed and adjusted, so that the position and size of the first through hole 21 that can conduct gas are also different. The position and size of the first through hole 21 that conducts gas can be adjusted according to the different materials being sucked up.

[0050] In some embodiments, such as Figure 5 As shown, the suction cup may also include:

[0051] Rotating cylinder 60 is disposed on the side wall of the second chamber 12, which is cylindrical. Rotating cylinder 60 can rotate on the side wall of the second chamber 12. A second through hole is provided on the rotating cylinder 60 at a position corresponding to the second through hole 22. The size and shape of the second through hole and the corresponding second through hole 22 can be exactly the same. A second through hole is provided on the rotating drum 60 at the position corresponding to the second through hole 22. During the rotation of the rotating drum 60, the second through hole and the corresponding second through hole 22 will be misaligned. For example, when the rotating drum 60 is not rotating, the second through hole and the corresponding second through hole 22 completely overlap and are connected. During the rotation of the rotating drum 60, the second through hole and the corresponding second through hole 22 partially overlap. The overlapping part of the second through hole 22 can conduct gas to form a vacuum. A vacuum can be formed through this position to suck up materials. During the rotation of the rotating drum 60, the position and size of the overlap between the second through hole and the corresponding second through hole 22 can be changed and adjusted, so that the position and size of the second through hole 22 that can conduct gas are also different. The position and size of the second through hole 22 that can conduct gas can be adjusted according to the different materials being sucked up.

[0053] The suction cup described in the above embodiments. A suction device with the suction cup described in the above embodiments can stack and suck up materials in the second chamber, enabling multiple materials to be simultaneously stacked and sucked up, thus improving the efficiency of material suction and handling.

[0054] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of the present invention.
