Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vacuum automation, and in particular relates to a vacuum suction cup. Background Technology
[0002] When handling thin, fragile materials or workpieces with high surface requirements (such as thin glass, photovoltaic panels, and wafers), conventional vacuum chucks with flat structures tend to cause stress concentration on the workpiece surface, leading to workpiece deformation or even breakage, making it impossible to achieve gentle gripping and adsorption. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a vacuum suction cup that can handle thin, deformable and fragile workpieces.
[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a vacuum suction cup, comprising a suction cup body and a connector, wherein the top of the suction cup body is sealed and fixedly fitted onto the connector, the bottom surface of the suction cup body is a honeycomb-shaped support surface, the honeycomb-shaped support surface extends to the inner edge of the lip of the suction cup body, and the channel in the honeycomb-shaped support surface is connected to the first channel of the suction cup body.
[0005] Preferably, the suction cup body has a corrugated support platform, and the lower part of the support platform has a compression compensation area, which is coaxially arranged with the first channel.
[0006] Preferably, the longitudinal section of the compression compensation region is set as a trapezoidal structure with a larger upper section and a smaller lower section.
[0007] Preferably, the channel width in the honeycomb support surface is 0.4mm-0.6mm, and the channel depth is 0.25-1.9mm.
[0008] Preferably, the inner wall of the second channel of the connector is provided with an anti-rotation bayonet.
[0009] Preferably, the channel depth and width dimensions in the honeycomb support surface decrease from the center to the edge.
[0010] Compared with the prior art, the advantages of this utility model are: 1. The honeycomb support surface design with extremely high reliability enables flexible gripping while the optimized airflow channel achieves a more uniform vacuum distribution, providing excellent sealing and holding force on clean surfaces for a more secure grip.
[0011] 2. Superior cycle performance: Thanks to its flat design and optimized flow channels, it still achieves rapid response. The filterless design results in lower flow resistance, enabling faster vacuuming and breaking speeds, making it particularly suitable for high-cycle applications.
[0012] 3. Excellent adaptability: The corrugated structure can compensate for height differences in workpieces and adapt to slightly curved surfaces. The universal corrugated design has a stronger ability to compensate for height differences, curved surfaces, and surface unevenness, and has a wider range of applications.
[0013] 4. Reduced downtime: Prevents downtime caused by workpiece deformation and breakage leading to blockage of the vacuum generator / pump, directly improving overall equipment efficiency. Its simple structure, reliable performance, and extremely low failure rate ensure continuous production.
[0014] 5. Lightweight: The suction cup body is made of rubber material, which is extremely lightweight, reducing the robot's load, improving movement speed and accuracy, and reducing energy consumption.
[0015] 6. Compact design: The suction cup body has a flat shape, which can easily enter narrow spaces for gripping and reduce interference with the surrounding environment.
[0016] 7. Simple maintenance: The connection between the top of the suction cup body and the connector can be replaced with the connector without disassembling the connector part. Attached Figure Description

[0021] Figure 4 This is a bottom view of the present invention. Detailed Implementation
[0022] The present invention will now be described in detail with reference to specific embodiments: like Figures 1 to 4 The vacuum suction cup shown includes a suction cup body 1 and a connector 2. The top of the suction cup body 1 is sealed and fixedly fitted onto the connector 2. The bottom surface of the suction cup body 1 is a honeycomb support surface, which extends to the inner edge of the lip 7 of the suction cup body 1. The channel in the honeycomb support surface is connected to the first channel 4 of the suction cup body 1.
[0023] The suction cup body 1 has a corrugated support platform 5, and the lower part of the support platform 5 has a compression compensation area 8, which is coaxially arranged with the first channel 4.
[0024] The longitudinal section of the compression compensation area 8 is set as a trapezoidal structure with a larger upper section and a smaller lower section. The compression compensation area 8 is similar in shape to the bottom of the support platform 5, which can make the bottom wall thickness of the support platform 5 consistent, making the compression compensation area 8 easier to compress and play a height compensation role.
[0025] The channel width in the honeycomb support surface is 0.4mm-0.6mm, and the channel depth is 0.25-1.9mm.
[0026] The inner wall of the second channel 21 of the connector 2 is provided with an anti-rotation latch 3. The anti-rotation latch 3 is fitted onto the disassembly and assembly fixture to prevent the connector 2 from rotating, so as to facilitate the quick disassembly and separation of the connector 2 from the suction cup body 1 from the fixture or quick installation onto the fixture.
[0027] The channel depth and width dimensions in the honeycomb support surface decrease from the center to the edge, with the center position being the central axis of the first channel 4.
[0028] Taking model SFF10 as an example, the channel groove width in its honeycomb support surface is 0.5mm-0.4mm, and the groove depth increases from 0.45mm at the center to 0.25mm at the edge.
[0029] Taking model SFF15 as an example, the channel groove width in its honeycomb support surface is 0.5mm-0.4mm, and the groove depth increases from 0.6mm at the center to 0.25mm at the edge.
[0030] Taking model SFF40 as an example, the channel width of its honeycomb support surface is 0.6mm-0.5mm, and the channel depth increases from 1.3mm at the center to 0.25mm at the edge.
[0031] The main application scenarios for this vacuum suction cup are: Used for gentle handling of sensitive plastics, capsules, or paper.
[0032] Used for the production of battery components (pouch cells).
[0033] Used for delicate or fragile workpieces, such as flat panel display glass and wafers.
[0034] The honeycomb support surface of the vacuum suction cup has the advantage of effective and uniform vacuum distribution, enabling deformation-free handling, i.e., flexible gripping; the flexible thin sealing lip 7 combined with the stable support surface, the honeycomb support surface ensures optimal uniform vacuum distribution, gently handles unstable, thin and fragile workpieces, does not deform and facilitates safe handling of components.
[0035] The suction cup body 1 is made of EPDM4520 or EPDM4570 material. The vacuum suction cup can meet various requirements (food safety material, chemical corrosion resistance, high temperature resistance).
