Description

Technical Field

[0001] This utility model relates to the field of vacuum suction cup components, and in particular to a vacuum suction cup component with a dual adsorption structure. Background Technology

[0002] Vacuum suction cup assemblies are widely used tools in automation, material handling, and manufacturing processes, typically for gripping and moving various objects. They generate suction force by creating a negative pressure area, thus firmly adhering to the surface of the object.

[0003] Existing technologies, such as the utility model with publication number CN211495995U, disclose a vacuum suction cup assembly with a dual adsorption structure. This patent employs a connector, a suction cup, and a connecting head. The connector has a magnetic snap-fit ​​structure at its top and a stacked pipe structure. A buffer structure is provided between the suction cup and the connector. The suction cup includes a suction cup body and a double-lip structure. This utility model, through the magnetic snap-fit ​​structure and connecting threads, allows for installation without being limited by the installation location, offering high applicability and convenient installation. The double-lip structure enables the suction cup assembly to withstand greater lateral shear force, improving load-bearing capacity, preventing workpiece detachment, and enhancing safety. The dual suction cup structure with one suction cup body and two suction cup bodies provides dual adsorption force, and the combination of inner and outer lips makes this vacuum suction cup assembly suitable for various types of workpieces. The textured design increases the friction between the suction cup assembly and the workpiece being suctioned, preventing slippage between the vacuum suction cup and the workpiece.

[0004] The inventor discovered in his daily work that when existing technicians use the first suction cup to move objects by adsorption, if the object is heavy or irregularly shaped, the suction force of the single first suction cup is limited and insufficient to maintain the stability of the object, which can lead to the object slipping off during movement.

[0005] Therefore, it is necessary to provide a new vacuum suction cup assembly with a dual adsorption structure to solve the above-mentioned technical problems. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figure 1 The present invention provides a vacuum suction cup assembly with a dual adsorption structure, comprising: a vacuum tube 1 and an adjustment structure 4. A first suction cup 2 is mounted on the lower surface of the vacuum tube 1, an auxiliary structure 3 is provided on the arc surface of the vacuum tube 1, and an adjustment structure 4 is provided on the surface of the second suction cup 312.

[0032] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The auxiliary structure 3 includes a fixing ring 301 and a connecting pipe 313. The fixing ring 301 is fixedly connected to the vacuum tube 1, and the connecting pipe 313 is fixedly and continuously connected to the vacuum tube 1. A fixing plate 302 is fixedly connected to the arc surface of the fixing ring 301. A positioning groove 303 is formed on the inner wall of the fixing plate 302. A moving plate 304 and a connecting plate 305 are slidably connected to the inner wall of the positioning groove 303. The moving plate 304 and the connecting plate 305 are fixedly connected. A plurality of positioning holes 306 are formed on the inner wall of the connecting plate 305. The plurality of positioning holes 306 are evenly spaced. A positioning plate 308 is fixedly connected to the side of the fixing plate 302 near the connecting plate 305, and a rod 309 is slidably connected to the inner wall of the positioning plate 308. A spring 311 is sleeved on the arc surface of the rod 309, and the two ends of the spring 311 are fixedly connected to the rod 309 and the positioning plate 308 respectively. The rod 309 is slidably connected to the positioning hole 306. A second suction cup 312 is installed on the side of the moving plate 304 away from the fixing plate 302 by means of the adjusting structure 4. The second suction cup 312 is fixedly and continuously connected to the connecting tube 313. When a person needs to move an object by adsorbing it with the first suction cup 2, the person can move the second suction cup 312 to a suitable distance by moving the rod 309 and the second suction cup 312, thereby improving the stability and installation during the adsorption process. A pull ring 310 is fixedly connected to the end of the rod 309 away from the positioning hole 306. The pull ring 310 has a hollow circular cross-section. The pull ring 310 facilitates the movement of the insertion rod 309, improving operational convenience. A guide block 307 is fixedly connected to the end of the insertion rod 309 near the positioning hole 306, and the guide block 307 is slidably connected to the positioning hole 306. The guide block 307 guides the insertion rod 309, allowing it to be easily slid into the inner wall of the positioning hole 306. The positioning plate 308 is made of stainless steel. Stainless steel has high strength and good wear resistance, preventing deformation of the positioning plate 308 during short-term use.

[0033] In the embodiments of this utility model, please refer to Figure 4The adjustment structure 4 includes a fixed block 41 and a positioning block 48. The fixed block 41 is fixedly connected to the second suction cup 312, and the positioning block 48 is fixedly connected to the second suction cup 312. Two limiting rods 44 are fixedly connected to the sides of the fixed block 41 and the positioning block 48 that are close to each other. The two limiting rods 44 are slidably connected to the moving plate 304. A compression spring 47 is sleeved on the arc surface of the limiting rod 44. The two ends of the compression spring 47 are fixedly connected to the moving plate 304 and the positioning block 48, respectively. A lead screw 45 is threadedly connected to the inner wall of the fixed block 41, and a rotating block 42 is fixedly connected to the upper end of the lead screw 45. When a person needs to move irregularly shaped objects by suction, the person can adjust the height of the second suction cup 312 by rotating the rotating block 42, thereby enabling stable suction of irregularly shaped objects and improving the applicability of the suction device. Several anti-slip grooves 43 are evenly distributed on the arc surface of the rotating block 42. The anti-slip groove 43 increases the friction between the operator's hand and the rotating block 42, preventing slippage during rotation. A protective pad 46 is fixedly connected to the end of the lead screw 45 furthest from the rotating block 42, and the protective pad 46 abuts against the moving plate 304. The protective pad 46 protects the moving plate 304 and the lead screw 45, preventing direct contact between them.

[0034] The working principle of the vacuum suction cup assembly with a dual adsorption structure provided by this utility model is as follows: When a person needs to use the first suction cup 2 to adsorb and move an object, the person can first use the pull ring 310 to move the insertion rod 309 away from the positioning hole 306. The pull ring 310 facilitates the movement of the insertion rod 309, improving the ease of operation. Then, the insertion rod 309 drives the guide block 307 to move away from the positioning hole 306. The guide block 307 guides the insertion rod 309, making it easy for the person to slide the insertion rod 309 into the inner wall of the positioning hole 306. Then, the insertion rod 309 also drives the spring 311 to stretch until the guide block 307 completely slides out of the inner wall of the positioning hole 306. Then, the person moves the second suction cup 312, causing the second suction cup to... 312 moves away from the fixed plate 302. The second suction cup 312 drives one end of the connecting tube 313 to move away from the fixed plate 302. The second suction cup 312 also drives the moving plate 304 to move away from the fixed plate 302 with the help of the adjusting structure 4. The moving plate 304 drives the connecting plate 305 to move away from the fixed plate 302 until the second suction cup 312 moves to the appropriate position. Then, when the pull ring 310 is released, the spring 311 rebounds and drives the insertion rod 309 to move towards the positioning hole 306 until the guide block 307 and part of the insertion rod 309 slide into the inner wall of the positioning hole 306. The positioning plate 308 is made of stainless steel and has high strength and good wear resistance, which can prevent the positioning plate 308 from deforming during short-term use.

[0035] In addition, when personnel need to move irregularly shaped objects by suction, they can first rotate the rotating block 42. The anti-slip groove 43 on the arc surface of the rotating block 42 can increase the friction between the personnel's hands and the rotating block 42, preventing the personnel from slipping during the rotation of the rotating block 42. Then the rotating block 42 drives the lead screw 45 to rotate, and the lead screw 45 drives the protective pad 46 to move upward. At this time, the two compression springs 47 rebound, and the two compression springs 47 drive the positioning block 48 to move downward. The positioning block 48 drives the second suction cup 312 to move downward. At this time, the moving plate 304 will slide on the arc surface of the two limit rods 44. The protective pad 46 can protect the moving plate 304 and the lead screw 45, preventing the lead screw 45 from directly contacting the moving plate 304, until the second suction cup 312 moves to the appropriate position.

[0036] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
