Abstract
Description
Technical Field
[0001] This utility model relates to the field of suction cup technology, specifically a suction cup structure with a return loop. Background Technology
[0002] Suction cups create a vacuum environment and use the pressure difference between the inside and outside to adsorb workpieces. When the vacuum generator is activated, the air inside the suction cup is extracted, creating a vacuum state. Because the air pressure inside the suction cup is lower than the external atmospheric pressure, the workpiece is tightly adsorbed under the action of external pressure. The material and design of the suction cup can protect the surface of the workpiece from damage. For example, in semiconductor manufacturing, suction cups are usually made of high-purity aluminum alloy or ceramic. These materials have excellent corrosion resistance and thermal stability, which can ensure stable operation in extreme environments while avoiding damage to precision components such as wafers. Suction cups can be customized according to the type and shape of the workpiece, and the design of the suction cup makes operation easier.
[0003] However, traditional suction cups have the following drawbacks:
[0004] Traditional suction cups have low stability after adsorption. Under external force, the suction cup may loosen from the adsorption point, requiring the user to fix the adsorption point again, which increases the adsorption cost of the suction cup. Utility Model Content
[0005] The purpose of this invention is to provide a retractable suction cup structure to solve the problem mentioned in the background art of low stability of traditional suction cups after adsorption, which may cause the suction cup to loosen from the adsorption point under external force, requiring the user to fix the adsorption point again, thus increasing the adsorption cost of the suction cup.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a suction cup structure with a return loop, comprising a suction cup base, a suction cup top shell fixedly connected to the top of the suction cup base, a ventilation pipe fixedly connected to the top of the suction cup top shell, a connecting component installed inside the ventilation pipe, a suction cup groove formed at the bottom of the suction cup base, four return blocks arranged in a rectangle fixedly installed at the bottom of the inner wall of the suction cup base, the connecting component comprising a connecting sleeve and three silicone blocks, one side of each of the three silicone blocks being fixedly connected to the outer side of the connecting sleeve, each of the four return blocks comprising an assembly rubber block and a return rubber block, one side of the assembly rubber block being connected to the return rubber block, a positioning component installed inside the connecting component, the positioning component comprising a hollow screw and a hollow height rod, the top of the hollow screw being fixedly connected to the bottom of the hollow height rod, a sliding platform movably connected to the middle of the hollow height rod, and suspension components rotatably installed on both sides of the sliding platform.
[0007] Preferably, telescopic rods are fixedly installed on both sides of the bottom of the sliding platform, and the movable ends of the two telescopic rods are fixedly connected to the connecting assembly. Two symmetrically arranged connecting springs are fixedly installed at the connection between the sliding platform and the connecting assembly. The threads on the surface of the hollow screw match the threads on the inner wall of the connecting assembly, so the hollow screw rotates and rises relative to the connecting assembly to adjust the distance between the connecting assembly and the positioning assembly. The sliding platform slides along the hollow screw to adjust the position of the suspension component, which facilitates the fixation of the suction cup structure.
[0008] Preferably, the hollow screw is threadedly connected to the connecting assembly, and the positioning assembly is mounted on the connecting assembly via the hollow screw.
[0009] Preferably, both suspension components include a rotating base and a mounting base. One side of the rotating base is fixedly connected to one side of the mounting base. A hook is rotatably mounted inside the mounting base. The other side of the rotating base is rotatably connected to a sliding platform. The user rotates the hook relative to the mounting base, and the suction cup is suspended at the point of use via the hook.
[0010] Preferably, one end of the assembled rubber block is fixedly connected to the suction cup groove, and the return block is installed on the suction cup groove through the assembled rubber block.
[0011] Preferably, the middle part of the connecting sleeve is fixedly connected to the ventilation pipe, and the connecting assembly is connected to the ventilation pipe through the connecting sleeve.
[0012] Preferably, a sealing ring is provided at the connection between the suction cup base and the suction cup top shell. The sealing ring fills the gap between the suction cup base and the suction cup top shell, thereby improving the sealing performance of the suction cup itself.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] By setting a return block and a suction cup base, an external vacuum pump vacuum adsorbs the gas inside the suction cup base through a pipeline, giving the suction cup base its own adsorption properties. The return block clamps and fixes the suction cup from the outside, improving the stability of the suction cup after adsorption and preventing the suction cup from loosening from the adsorption area, thus reducing the cost of suction cup adsorption.

[0022] Please see Figure 1-5 This utility model provides a suction cup structure with a return loop, including a suction cup base 1, a suction cup top shell 7 fixedly connected to the top of the suction cup base 1, a ventilation pipe 3 fixedly connected to the top of the suction cup top shell 7, a connecting component 4 installed inside the ventilation pipe 3, a suction cup groove 6 opened at the bottom of the suction cup base 1, and four return blocks 5 arranged in a rectangle fixedly installed at the bottom of the inner wall of the suction cup base 1. The connecting component 4 includes a connecting sleeve 41 and three silicone blocks 42. One side of each of the three silicone blocks 42 is fixedly connected to the outside of the connecting sleeve 41. Each of the four return blocks 5 includes an assembly rubber block 51 and a return rubber block 52. One side of the assembly rubber block 51 is connected to the return rubber block 52. A positioning component 8 is installed inside the connecting component 4. The positioning component 8 includes a hollow screw 81 and a hollow height rod 82. The top of the hollow screw 81 is fixedly connected to the bottom of the hollow height rod 82. A sliding table 83 is movably connected to the middle of the hollow height rod 82. Suspension parts 84 are rotatably installed on both sides of the sliding table 83.
[0023] Telescopic rods 85 are fixedly installed on both sides of the bottom of the sliding platform 83. The movable ends of the two telescopic rods 85 are fixedly connected to the connecting component 4. Two symmetrically arranged connecting springs 86 are fixedly installed at the connection between the sliding platform 83 and the connecting component 4. The threads on the surface of the hollow screw 81 match the threads on the inner wall of the connecting component 4. Therefore, the hollow screw 81 rotates and rises relative to the connecting component 4 to adjust the distance between the connecting component 4 and the positioning component 8. The sliding platform 83 slides along the hollow height rod 82 to adjust the position of the suspension component 84, which facilitates the fixation of the suction cup structure.
[0024] The hollow screw 81 is threadedly connected to the connecting assembly 4, and the positioning assembly 8 is mounted on the connecting assembly 4 via the hollow screw 81.
[0025] Both suspension components 84 include a rotating base 841 and a mounting base 842. One side of the rotating base 841 is fixedly connected to one side of the mounting base 842. A hook 843 is rotatably mounted inside the mounting base 842. The other side of the rotating base 841 is rotatably connected to the sliding table 83. The user rotates the hook 843 relative to the mounting base 842, and the suction cup is suspended at the point of use by the hook 843.
[0026] One end of the assembled rubber block 51 is fixedly connected to the suction cup groove 6, and the return block 5 is installed on the suction cup groove 6 through the assembled rubber block 51.
[0027] The middle part of the connecting sleeve 41 is fixedly connected to the ventilation pipe 3, and the connecting component 4 is connected to the ventilation pipe 3 through the connecting sleeve 41.
[0028] A sealing ring 2 is fitted at the connection between the suction cup base 1 and the suction cup top shell 7. The sealing ring 2 fills the gap between the suction cup base 1 and the suction cup top shell 7, thereby improving the sealing performance of the suction cup itself.
[0029] In this embodiment, the threads on the surface of the hollow screw 81 match the threads on the inner wall of the connecting component 4, so the hollow screw 81 rotates and rises relative to the connecting component 4, adjusting the distance between the connecting component 4 and the positioning component 8. The sliding table 83 slides along the hollow height bar 82, adjusting the position of the suspension component 84 to facilitate the fixation of the suction cup structure. The user rotates the hook 843 relative to the mounting base 842, and the suction cup is suspended at the point of use by the hook 843. The vacuum pump is connected to the positioning component 8 through an external pipe. The pipe on the vacuum pump vacuum adsorbs the positioning component 8 and the connecting component 4, so that the suction cup base 1 and the suction cup top shell 7 have their own adsorption properties. The suction cup base 1 is vacuum adsorbed at the point of use, and the four return blocks 5 limit and fix it from the side of the adsorption point. The sealing ring 2 fills the gap between the suction cup base 1 and the suction cup top shell 7 to improve the sealing of the suction cup itself.
