[0036] At present, the suction cup type feeding device for the bending machine adopts a plurality of suction cup mechanisms, the surface of the sheet material is adsorbed by the suction cup, the device drives the sheet material to move and places the sheet material on the bending machine for bending, although the existing suction cup device can effectively limit the movement of the sheet material in the axial direction of the suction cup, and plays a adsorption fixing role, but the sheet material is still easy to slide relative to the suction cup device in the direction perpendicular to the axial direction of the suction cup, so that the phenomenon of sheet material displacement occurs, reducing the accuracy of bending.

[0037] In order to solve the above problems, the utility model provides a kind of suction cup mechanism, solve the problem of sheet material sliding.

[0038] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 And Figure 6 , a kind of suction cup mechanism of the utility model makes the following embodiments:

[0039] A kind of suction cup mechanism of the embodiment includes: suction cup seat 100, antiskid layer 160 and sealing ring 170.

[0040] As shown in Figure 1 , one side of suction cup seat 100 is adsorption surface 120, and adsorption surface 120 is a rounded rectangular plane, in other embodiments, adsorption surface 120 can be other shapes, such as circular, oval, etc.

[0041] Suction cup seat 100 of the embodiment is provided with suction channel 110, and adsorption surface 120 is provided with adsorption slot structure 130, suction channel 110 is communicated with adsorption slot structure 130, in use, vacuum generator is connected with suction channel 110.

[0042] Sealing ring 170 is arranged along the four around adsorption surface 120 closed loop, and is consistent with the shape of the outer periphery of adsorption surface 120, is convenient for installation, the appearance is more unified as a whole, and adsorption slot structure 130 is arranged in the range of sealing ring 170, in actual use, sealing ring 170 directly contacts the surface of sheet material, adsorption surface 120, sealing ring 170 and sheet material surface jointly define a closed space, and then form a seal, further, sealing ring 170 is a soft member, in the embodiment, high modulus rubber ring is selected, which can increase the contact area of sealing ring 170 and sheet material, improve the sealing property, and be conducive to improving the vacuum degree of suction cup mechanism.

[0043] Further, as shown in Figure 4 the cross section of the sealing ring 170 is trumpet-shaped, the caliber gradually increases from the adsorption surface 120 to the outside, to some extent, increase the adsorption port caliber, increase the contact area of the sealing ring 170 and the sheet material, to improve the sealing, and then improve the reliability and stability of the adsorption fixation.

[0044] Because the sealing ring 170 is a consumable part, it needs to be replaced in time, and the sealing ring 170 and the adsorption surface 120 must be connected through a quick release structure. In this embodiment, a fixed ring groove 180 matched with the sealing ring 170 is arranged around the adsorption surface 120, and the sealing ring 170 is fixedly installed in the fixed ring groove 180. In other embodiments, the sealing ring 170 can be connected with the adsorption surface 120 in other ways, such as installation clamps, buckles, etc.

[0045] As shown in Figure 3 , in order to improve the stability of the sheet material adsorption, the adsorption slot structure 130 of the embodiment includes a plurality of longitudinal and transverse intersecting adsorption grooves 131. The adsorption grooves 131 of the embodiment are divided into transverse grooves and longitudinal grooves. The transverse grooves extend along one side direction parallel to the adsorption surface 120 and are uniformly arranged. The longitudinal grooves extend along the other side direction parallel to the adsorption surface 120 and are uniformly arranged. Each adsorption groove 131 is connected with each other to expand the range of adsorption.

[0046] In other embodiments, the adsorption slot structure 130 can be in the form of multiple slots.

[0047] As shown in Figure 4 , the air extraction channel 110 and the adsorption slot structure 130 together constitute a vacuum channel connecting the vacuum generator and the adsorption surface 120, so that only one vacuum generator needs to be connected to produce uniform adsorption fixation effect on the entire adsorption surface 120. Compared with the existing suction disc device composed of multiple suction disc mechanisms, the production cost can be effectively reduced. When the external vacuum generator starts to work, the sheet material is adsorbed and fixed on the adsorption surface 120 under the action of atmospheric pressure. The movement of the sheet material in the direction perpendicular to the adsorption surface 120 is limited, but it is still possible to slide along the adsorption surface 120.

[0048] In order to limit the movement of the sheet material along the adsorption surface 120 and prevent the sheet material from sliding to reduce the accuracy of bending or bring production safety risk, the adsorption surface 120 is also provided with an anti-skid layer 160 for increasing the friction between the adsorption surface 120 and the sheet material, further improving the stability and reliability of the sheet material adsorption on the basis of vacuum adsorption, as shown in Figure 1As shown, in this embodiment, the anti-slip layer 160 is a friction film attached to the adsorption surface 120. The friction film can be cut according to the shape and size of the adsorption surface 120 to meet different needs in actual production. At the same time, the friction film can be flexibly installed and easily replaced after wear. In some other embodiments, the function of the anti-slip layer 160 can be achieved by other structures, such as designing anti-slip textures on the adsorption surface 120, which only needs to meet the requirement of preventing slippage and displacement.

[0049] Among them, such as Figure 1 As shown, in order to prevent the anti-slip layer 160 from blocking the gap between the adsorption groove structure 130 and the adsorption surface 120 and the sheet metal, the anti-slip layer 160 is evenly distributed with a plurality of air passage holes 161 corresponding to the adsorption groove structure 130. Specifically, on the projection surface of the suction cup seat 100 in the thickness direction, the air passage holes 161 coincide with the intersection point between the transverse groove and the longitudinal groove.

[0050] Furthermore, the suction cup holder 100 also includes a connector 140 for connecting to a peripheral robotic arm, such as... Figure 2 As shown, the connector 140 is a cylindrical component located on the side opposite to the adsorption surface 120, extending along the thickness direction of the suction cup seat 100. In order to balance the force, the connector 140 is located at the center of the suction cup seat 100 to prevent the center of gravity from shifting and causing tipping.

[0051] like Figure 4 As shown, the exhaust channel 110 has an exhaust port 111 at its end. The exhaust port 111 is located at the end of the connector 140 away from the adsorption surface 120. The exhaust channel 110 connects the adsorption groove structure 130 and the exhaust port 111 to form a complete vacuum channel. During installation, it can be connected to an external vacuum generator. In this embodiment, the exhaust port 111 is a countersunk hole structure with an inner diameter larger than that of the exhaust channel 110. It has a circumferential positioning part on its inner circumference. The cross-sectional shape of the exhaust port 111 is axially symmetrical, thereby satisfying the limiting function so that it can be easily and accurately installed in actual use. In some other embodiments, circumferential limiting can be achieved by other means, such as designing a limiting groove on the inner wall of the exhaust port 111.

[0052] like Figure 5 and Figure 6 As shown, the suction cup base 100 in this embodiment also includes a plurality of mounting channels 150 for mounting the suction cup mechanism. The plurality of mounting channels 150 are arranged in a ring at intervals on the outer periphery of the air extraction port 111. The mounting channels 150 extend along the thickness direction of the suction cup base 100, and the two ends respectively penetrate the adsorption surface 120 and the connector 140. In actual use, the suction cup base 100 can be mounted on the mechanical arm of the external device by screwing screws into the mounting channels 150.

[0053] Further, the mounting hole 150 at one end of the adsorption surface 120 is a tapered structure, which provides self-positioning function when screwing in the screw, facilitating the installation of the suction cup mechanism. In other embodiments, the installation of the suction cup seat 100 can be achieved by other means, such as buckle structure, clamping groove structure, etc.

[0054] For the use of the present embodiment: when adsorbing the plate, the sealing ring 170 is in contact with the plate to form a seal, and the connector 140 is connected to the vacuum generator, and the vacuum generator performs vacuumization, and the plate is adsorbed and fixed on the suction cup mechanism under the action of atmospheric pressure, thereby limiting the movement of the plate in the thickness direction of the suction cup seat 100. Since the plate is closely attached to the anti-skid layer 160, the sliding of the plate on the adsorption surface 120 is limited by the friction between the plate and the anti-skid layer 160, further enhancing the stability of the adsorption and fixation, and improving the safety of production and the accuracy of bending.

[0055] At the same time, the air exhaust channel 110 is in communication with the adsorption slot structure 130, which expands the range of adsorption, meets the uniform stress between the plate and the adsorption surface, so that only one vacuum generator is needed to complete the adsorption, reduces the production cost, and the overall structure of the suction cup mechanism is more simple.

[0056] In the description of the present specification, the description of the terms "one embodiment", "some embodiments", "illustrative embodiment", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0057] The embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present application.
