Description

Technical Field

[0001] The utility model relates to the technical field of corrugated vacuum suckers, and particularly relates to a corrugated vacuum sucker. Background Art

[0002] Corrugated vacuum suckers are mainly used in automation and handling systems to help adsorb and move smooth or slightly uneven surface objects, such as glass, metal plates or plastic parts.

[0003] The current corrugated vacuum sucker mainly consists of a joint assembly and an integrated corrugated suction pipe installed at the suction port of the joint assembly. Although the corrugated vacuum sucker with this structure can achieve the adsorption and handling of glass, metal plates, plastic parts, etc. during use, when using this structure of corrugated vacuum sucker, it is easy to have poor flexibility at the bottom end of the corrugated pipe on the sucker, resulting in insufficient adsorption when the corrugated vacuum sucker adsorbs and handles some plates with larger surface roughness, so that the adsorption force of the corrugated vacuum sucker on the plate with larger surface roughness is small, and there is a drawback that the plate falls during the adsorption and handling process. Summary of the Utility Model

[0004] (I) Technical Problems to be Solved

[0005] The technical problem to be solved by the utility model is to provide a corrugated vacuum sucker that can achieve stable adsorption of plates with larger surface roughness by increasing the softness of the flexible lip edge, and avoid the plate from falling during the adsorption and handling process, aiming at the current situation of the prior art.

[0006] (II) Technical Solutions

[0007] The utility model is realized through the following technical solutions: The utility model provides a corrugated vacuum sucker, which includes a corrugated pipe. A flexible lip edge is installed at the bottom end of the corrugated pipe. A connecting ring edge is installed at the connection part between the outer periphery of the upper end of the flexible lip edge and the corrugated pipe. And the connection part between the bottom end of the corrugated pipe and the connecting ring edge is a necking structure. A disk seat is also installed at the top end of the corrugated pipe, and a joint assembly is installed at the top end of the disk seat.

[0008] Furthermore, the corrugated pipe is a transparent pipe made of TPU material. The necking part at the bottom end of the corrugated pipe extends into the flexible lip edge and is in interference fit with the flexible lip edge.

[0009] By adopting the above technical solutions, the corrugated pipe made of TPU material is a recyclable part, which can reduce the use cost of the corrugated vacuum sucker.

[0010] Furthermore, the flexible lip edge is a flared structure made of TPE material, and the necking part of the flexible lip edge is fixedly connected with the corrugated pipe.

[0011] By adopting the above technical solution and using the flexible lip made of a material different from that of the bellows, the suction cup has the dual advantages of being stable and flexible.

[0012] Furthermore, the bellows is a three-section telescopic structure, and anti-slip patterns are arranged on opposite side walls in each section of the telescopic structure.

[0013] By adopting the above technical solution, the anti-slip pattern is designed mainly to avoid rotational dislocation of the expansion and contraction part of the bellows after compression during the adsorption process.

[0014] Furthermore, the disc seat is sealed and fixed to the exhaust port at the top end of the bellows, and the disc seat is a trumpet-mouth structure made of TPU material.

[0015] By adopting the above technical solution, the disc seat is mainly used to ensure the reliable installation and fixation of the joint assembly.

[0016] Furthermore, the large opening end of the disc seat faces the interior of the bellows, and the narrowed end of the disc seat faces the joint assembly.

[0017] By adopting the above technical solution, it can be ensured that the gas in the bellows can be smoothly drawn away by the joint assembly through the disc seat.

[0018] Furthermore, the joint assembly includes a connection clamp directly bonded and fixed to the exhaust port provided at the top of the disc seat, a hexagonal nut installed outside the connection clamp, and a sealing ring installed on the upper side of the hexagonal nut.

[0019] By adopting the above technical solution, the connecting clamp is mainly connected to the external suction pipe, so as to realize the convenient extraction of air in the space behind the flexible lip.

[0020] Furthermore, the hexagonal nut is screwed with the thread on the outside of the connecting clamp, and the sealing ring is a ring made of rubber material.

[0021] By adopting the above technical solution, after tightening the hexagonal nut, reliable locking of the external air extraction pipeline and the connecting clamp can be achieved.

[0022] (III) Beneficial effects

[0023] Compared with the prior art, the utility model has the following beneficial effects:

[0024] In order to solve the problem that the current corrugated vacuum suction cup is mainly composed of a joint assembly and an integrated corrugated suction pipe installed at the suction port of the joint assembly, although the corrugated vacuum suction cup of this structure can realize the adsorption and transportation of glass, metal plates and plastic parts when in use, the corrugated vacuum suction cup of this structure is easy to be used in use due to the poor flexibility of the bottom end of the bellows on the suction cup, resulting in the corrugated vacuum suction cup not adsorbing tightly enough when adsorbing and transporting some plates with large surface roughness, so that the adsorption force of the corrugated vacuum suction cup on the plates with large surface roughness is small, and there is a problem that the plates fall off during the adsorption and transportation process. The utility model installs a flexible lip of TPE material on the lower side of the bellows made of TPU material, so that the softness of the flexible lip of the corrugated vacuum suction cup of this structure is better when in use, ensuring that the corrugated vacuum suction cup can fit tightly with the surface of the plate with large roughness when in use, so as to ensure the adsorption force of the corrugated vacuum suction cup on the plate, avoid the falling of the plate during the adsorption and transportation process, and make the corrugated vacuum suction cup more stable when in use.

[0031] like Figure 1 - Figure 2 As shown, in this embodiment, the bellows 2 is a transparent tube made of TPU material. The necked portion at the bottom of the bellows 2 extends into the flexible lip 3 and has an interference fit with the flexible lip 3. The bellows 2 made of TPU material is a recyclable part, which can reduce the use cost of the bellows vacuum suction cup.

[0032] like Figure 1 - Figure 2 As shown, in this embodiment, the bellows 2 is a three-section telescopic structure, and anti-slip grooves 6 are provided on the opposite side walls in each section of the telescopic structure.

The disc seat 1 is mainly used to ensure the reliable installation and fixation of the joint assembly 5.
