[0039] Example:

[0040] like Figure 1 and Figure 2 As shown, the present invention provides a suction cup clamp, comprising: a flange 1, a first link beam assembly, a second link beam assembly, and a clamping claw 5; wherein the flange 1 is used to connect to the end of a transfer device (such as the end of an industrial robot arm, the end of a crane, etc.); the first link beam assembly includes at least one first link beam 2, each of the first link beams 2 extending axially along a first horizontal direction, and the first link beam assembly is connected to the flange 1;

[0042] Each of the second connecting rod beams 3 is provided with at least one clamping claw 5, and the clamping claw 5 includes a first support rod 6, a second support rod 7, a second connecting member 8, a third connecting member 9 and a suction cup 10; the first end of the first support rod 6 is connected to the second connecting rod beam 3 through the second connecting member 8, so that the first support rod 6 is rotatably arranged on the second connecting rod beam 3 around the second horizontal direction, thereby realizing angle adjustment between the first support rod 6 and the second horizontal direction; the second support rod 7 is connected to the second end of the first support rod 6 through the third connecting member 9, so that the second support rod 7 is rotatably arranged at the second end of the first support rod 6 around the second horizontal direction, thereby realizing angle adjustment between the second support rod 7 and the first support rod 6, and the suction cup 10 is installed at the end of the second support rod 7.

[0043] In the suction cup clamp of the present invention, its second connecting rod beam 3 can move along the first connecting rod beam 2 (i.e., move along the first horizontal direction), thereby adjusting the horizontal displacement of the suction cup, the first support rod 6 of the clamp 5 can rotate around the second connecting rod beam 3 (i.e., rotate around the second horizontal direction), and the second support rod 7 of the clamp 5 can also rotate around the second horizontal direction, thereby adjusting the angle of the end suction cup through the first support rod 6 and the second support rod 7, thereby realizing spatial adjustment of the end suction cup, so that the adsorption surface of the end suction cup can be adaptively adjusted according to the glass surface, more closely fitting the glass surface, and stably clamping the special-shaped glass. By adjusting the position and angle of the suction cup, special-shaped glasses of different sizes, types, and curvatures can be satisfied, and the utility model has strong versatility. A flange 1 is provided in the present invention to facilitate its fixation at the end of other transporting equipment, such as an industrial robot arm, to realize the spatial transport of glass, and is suitable for long-distance spatial transport of special-shaped glass.

[0044] like Figure 3 and Figure 4 As shown, the second support rod 7 is a telescopic rod, so that the suction cup can be extended and retracted along the axial direction of the second support rod 7. By setting the second support rod 7 as a telescopic rod, the end suction cup can be extended and retracted along the axial direction of the second support rod 7. When multiple clamps work together, they can overcome the distance difference of the special-shaped glass surface, allowing multiple clamps to simultaneously adhere to the special-shaped glass surface, thereby improving work efficiency.

[0045] Preferably, the structure of the second support rod 7 in the present invention is as follows: the second support rod 7 includes a sleeve 701, a sliding rod 702, and an elastic member 703; the sleeve 701 is connected to the second end of the first support rod 6 via a third connecting member; the sleeve 701 defines an axially extending receiving cavity; the first end of the sliding rod 702 is slidably disposed within the receiving cavity; the second end of the sliding rod 702 is located outside the sleeve 701 for mounting the suction cup 10; the elastic member 703 is disposed within the receiving cavity of the sleeve 701 and is configured to cooperate with the sliding rod 702 to provide elastic force to the sliding rod 702 as it slides along the receiving cavity. The elastic member 703 is a spring or a spring. In a specific embodiment, a baffle is disposed within the sleeve 701; the first end of the elastic member 703 is connected to the baffle; and the second end of the elastic member 703 is connected to the sliding rod 702. This provides elastic force to the sliding rod 702 during its sliding process, helping the suction cup overcome displacement differences on the surface of the irregularly shaped glass and reset itself in a timely manner.

[0046] Specifically, a first limiting mechanism is disposed within the housing cavity of sleeve 701. The first limiting mechanism includes a limiting block 11 located on the inner wall of the housing cavity of sleeve 701 and configured to cooperate with sliding rod 702 to prevent the first end of sliding rod 702 from exiting the housing cavity. A protrusion is disposed on the top of sliding rod 702, projecting radially outward from the rod, thereby cooperating with limiting block 11 to prevent sliding rod 702 from exiting the housing cavity.

[0047] This embodiment further includes a stopper 12 disposed on the outer periphery of the sliding rod 702 to limit the length of the sliding rod that can slide into the receiving cavity. In practice, the stopper 12 can be a bolt disposed on the outer periphery of the sliding rod 702. This not only limits the length of the sliding rod 702 that can extend into the receiving cavity, but also allows for mounting the vacuum cup.

[0048] Preferably, the suction cup 10 is a vacuum cup, mounted at the end of the sliding rod 702, to achieve vacuum adsorption of the surface of the clamped object. The vacuum cup is made of plastic, making it easy and stable to grasp, harmless to glass, and highly durable. A first air path 13 communicating with the suction cup 10 is defined within the sliding rod 702. The first air path 13 is connected to an external air pipe via the accommodating cavity of the sleeve 701. A baffle within the sleeve also defines an air pipe passage, facilitating connection of the first air path 13 to the external air pipe.

[0049] Reference Attachment Figure 1 and attached Figure 2In this embodiment, the first connecting beam assembly includes multiple first connecting beams 2, and the multiple first connecting beams 2 are symmetrically distributed along both sides of the flange 1. The first connecting beams 2 on the same side of the flange 1 are arranged side by side and spaced apart along the second horizontal direction. In specific implementation, the lower surface of the flange is provided with mounting buckles or clamps for securing the first connecting beams 2. The first connecting beams 2 are not on both sides of the flange, which can extend the position of the end suction cup along the first horizontal direction. The first connecting beams 2 on both sides of the flange are provided with second connecting beams and clamps, which can improve the balance of the suction cup clamp during clamping and transportation.

[0050] Multiple second connecting beams 3 are provided on the first connecting beam 2 located on the same side as the flange 1. The multiple second connecting beams 3 are evenly distributed along the extension direction of the first connecting beam 2. In this embodiment, the length of each second connecting beam 3 matches the arrangement span of the multiple first connecting beams 2 along the second horizontal direction, so that the second connecting beams 3 can be simultaneously connected to all the first connecting beams 2 located on the same side as the flange, thereby increasing the stability of the second connecting beams 3 and facilitating the adjustment of the position of the second connecting beams 3 along the first horizontal direction.

[0051] In another embodiment, the second connecting beam 3 is individually connected to the first connecting beam 2 , which can increase the position flexibility of the clamping jaw 5 .

[0052] A plurality of the clamping claws 5 are provided on each of the second connecting rod beams 3, and the plurality of the clamping claws 5 are evenly distributed along the extension direction of the second connecting rod beam 3. The plurality of clamping claws 5 can improve the adsorption stability of the suction cup clamp.

[0053] like Figure 1 and Figure 2 As shown, the first connecting member 4 includes a positioning seat 401 and a handle 402; the positioning seat 401 includes a first snap ring 403 and a second snap ring 404 distributed vertically. The axial direction of the first snap ring 403 is distributed along the first horizontal direction and is used to cooperate with the first connecting beam 2. The handle 402 is used to adjust the opening size of the first snap ring 403. The axial direction of the second snap ring 404 is distributed along the second horizontal direction and is used to cooperate with the second connecting beam 3. In this embodiment, the first connecting member 4 has a simple structure and is easy to operate. It can connect the first connecting beam 1 distributed along the first horizontal direction and the second connecting beam 3 distributed along the second horizontal direction. At the same time, by rotating the handle 402, the opening size of the first snap ring 403 can be easily adjusted, thereby adjusting the position of the second connecting beam 3 along the first horizontal direction.

[0054] The first retaining ring 403 includes a first upper retaining ring and a first lower retaining ring; the first upper retaining ring and the first lower retaining ring are butted together and bolted together to confine the first connecting beam 2 within the first retaining ring 403. The handle 402 is connected to a bolt on one side and is used to rotate the handle 402 to adjust the opening of the first retaining ring 403. The second retaining ring 404 has a similar structure to the first retaining ring 403, but does not require a handle 402. It specifically includes a second upper retaining ring and a second lower retaining ring, which are butted together and bolted together to confine the first connecting beam within the second retaining ring. The first and second retaining rings 403 and 404 have simple structures, and the handle 402 is also provided to facilitate adjustment of the opening size of the first retaining ring 403.

[0055] like Figure 1 、 Figure 2 and Figure 3 As shown, the second connecting member 8 includes a clamp, which includes a clamp ring 14 and a fastening bolt 15. The clamp ring 14 is sleeved on the outer periphery of the second connecting rod beam. The clamp ring 14 has an opening along its inner radial direction. The opening has locking portions 18 on both sides. The fastening bolts 15 cooperate with the locking portions 18 to adjust the size of the clamp ring 14. The clamp ring 14 is also connected to the first support rod 6 via the fastening bolts 15. The fastening bolts 15 are also used for threaded connection with the sleeve 701. During use, the sleeve 701 can be rotated about the second horizontal direction by loosening the fastening bolts 15, thereby adjusting the angle of the suction cup 10.

[0056] The locking portion 18 includes a sleeve 701 with an internal thread; the sleeve 701 is respectively located on both sides of the opening, and the inner cavities of the two sleeves 701 are arranged relative to each other, so that the fastening bolt 15 is threadedly connected to the sleeves on both sides of the opening, which can not only tighten the clamp ring 14, but also facilitate the adjustment of the ring size of the clamp ring 14.

[0057] The third connecting member 9 includes a clamp and a holder 16; the clamp in the third connecting member 9 has the same structure as the clamp in the second connecting member 8, and is mounted on the second end of the first support rod 6. The holder 16 is provided on the outer wall of the sleeve 701 and has a connecting rod 17 extending axially along the second horizontal direction. The connecting rod 17 is used to connect to the ring opening of the clamp. By adjusting the ring opening of the clamp, the connecting rod 17 can rotate about its own axis, thereby adjusting the angle of the second support rod 7. In this embodiment, the first, second, and third connecting members are provided to quickly adjust the position and angle of the suction cup, which is simple to operate and low in cost.

[0058] The following describes the specific working steps of the suction cup clamp for sucking and clamping special-shaped glass in this embodiment, taking curved glass as an example, but the actual work is not limited to curved glass.

[0059] 1. Preparation before clamping: According to the size of the glass, adjust the distance between the clamping jaws of the suction cup clamp along the first horizontal direction (adjust the position of the second connecting beam on the first connecting beam) so that the center of the suction cup clamp is basically located at the center of the glass, so as to avoid a large overturning force and ensure safety during handling;

[0060] 2. When the vacuum suction cup at the end starts to absorb, the suction cup fixture slowly descends. Due to the bulge of the glass, the sliding rods of the several clamping claws on the inner side close to the flange extend upward.

[0061] 3. When the end vacuum suction cup is adsorbing; when the suction cups of all the jaws are in contact with the glass surface, first adjust the angles of the first support rod and the second support rod so that the adsorption surface of the end vacuum suction cup is tangent to the glass surface. After the end vacuum suction cups of all the jaws are completed, operate the transfer equipment (drive the suction cup clamp downward) to extend and retract the sliding rod of the jaw so that the adsorption surface of the end vacuum suction cup is in close contact with the glass surface. The vacuum pump starts to work, and a local vacuum is formed in the contact area between the suction cup and the glass to provide adsorption force to achieve clamping of the glass.

[0062] After the clamping operation is completed, the device transfers the glass to the designated position and then slowly descends to the platform supporting the glass. After the bottom of the glass is completely placed and stabilized, the vacuum pump stops working, the end vacuum suction cup separates from the glass, and the equipment starts to rise and returns to its initial position to continue the next clamping operation.

[0063] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
