Description

Technical Field

[0001] This utility model relates to the field of suction cup structure technology, and in particular to a double-headed suction cup structure. Background Technology

[0002] In modern industrial production and logistics handling, suction cups, as a common gripping and fixing device, are widely used in the handling and positioning of non-magnetic materials such as glass, metal sheets, and plastic products. Traditional suction cups typically employ a single-structure design, using negative pressure adsorption to grasp target objects, and are characterized by simple structure and convenient operation. However, with the continuous improvement of industrial automation and the increasing complexity of work scenarios, single suction cups often suffer from insufficient adsorption force, poor stability, and weak adaptability when dealing with larger or heavier objects, making it difficult to meet the needs of efficient, precise, and safe multi-target gripping.

[0003] Chinese patent discloses a suction cup (publication number: CN 204942239 U) comprising: a pressure-resisting component that can be pressed against the periphery of the disk body to form a closed annular contact with the disk body; a lifting component that is fixedly connected to the center of the disk body and can lift the center of the disk body; and an triggering component located above the pressure-resisting component and connected to the lifting component by a threaded connection. However, this suction cup structure has significant shortcomings in terms of adsorption force, stability, adaptability, and intelligence level, making it difficult to meet the needs of simultaneous grasping of multiple targets and efficient operation under complex working conditions. Therefore, a dual-head suction cup structure is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of traditional single suction cup structures in terms of adsorption force, stability, adaptability, and intelligence, which make it difficult to meet the needs of simultaneous grasping of multiple targets and efficient operation under complex working conditions. Therefore, a dual-head suction cup structure is proposed.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A dual-head suction cup structure, comprising independent suction heads, characterized in that: the number of independent suction heads is two and correspondingly arranged, each independent suction head includes a suction cup body, the suction cup body has a corrugated structure and a flexible sealing lip on its bottom edge; a rigid connecting plate is provided between the suction cup bodies, the top center of the rigid connecting plate has an air chamber, and multiple connection ports are provided around the outer wall of the air chamber. Each connection port includes a metal connecting nut and a sealing component, one end of the connection port has a black flexible tube, and one end of the black flexible tube has an adjustable connecting screw, the adjustable connecting screw cooperating with the suction cup body. The dual-head structure allows for the simultaneous adsorption of two target objects, improving work efficiency and adsorption stability; the corrugated structure of the suction cup body enhances its flexibility and adaptability, allowing it to better conform to irregular surfaces; the flexible sealing lip improves airtightness during adsorption, preventing air leakage and enhancing adsorption reliability; the rigid connecting plate maintains a stable relative position for the two suction heads, ensuring synchronous operation.

[0006] The air chamber centrally manages airflow, facilitating unified control and distribution; the multiple connection ports support multi-line air tube connections, enhancing structural scalability and adaptability; the adjustable connection screw provides fine-tuning capability for adsorption force or connection position, enhancing operational flexibility.

[0007] Preferably, a parameter display screen is provided on the top surface of the air chamber, and an integrated sensor is provided inside the suction cup body. The integrated sensor works in conjunction with the parameter display screen. The parameter display screen can intuitively show the working status of the suction cup, allowing operators to understand the adsorption situation in a timely manner; the integrated sensor enables real-time monitoring of the internal status of the suction cup, improving the intelligence level of the equipment; the linkage between the sensor and the display screen allows operators to make timely adjustments based on feedback information, improving operational safety and reliability.

[0008] Preferably, a protective frame is provided above the air chamber, the bottom of which is connected to the top of the rigid connecting plate. An arc-shaped handle is located at the center of the top of the protective frame, and the handle has an anti-slip coating. The protective frame protects the air chamber and its internal structure, reducing the risk of external collisions or damage. The arc-shaped handle is ergonomically designed, facilitating grip and force application, thus improving operational comfort. The anti-slip coating enhances the friction between the handle and the hand, reducing the possibility of slipping during operation and improving safety.

[0009] Preferably, the rigid connecting plate is provided with two hollow triangular grooves, which are correspondingly arranged. The hollow triangular groove design helps to reduce the overall structural weight, achieving lightweighting while ensuring strength; structural optimization improves the overall flexibility and ease of operation; it also helps to improve the airflow characteristics or heat dissipation performance of the structure (depending on the specific application), enhancing the user experience.

[0010] Preferably, a pressure relief valve is provided on one side of the outer wall of the gas chamber. The pressure relief valve can quickly release the internal pressure of the gas chamber when needed, improving operational safety; in emergency situations or when it is necessary to quickly release the adsorption state, the pressure relief valve provides a convenient release method, avoiding equipment damage or operational risks.

[0011] Preferably, the surface of the suction cup body is coated with a wear-resistant coating, which is made of polyurethane or polytetrafluoroethylene (PTFE). The wear-resistant coating significantly improves the surface wear resistance of the suction cup body, extending its service life; the coating material has good corrosion resistance and chemical stability, making the suction cup suitable for various complex or harsh working environments; it improves the performance stability of the suction cup during long-term use, reducing the frequency of maintenance and replacement.

[0012] The advantages of this utility model are:

[0013] This application's dual-head suction cup structure, through the setting of two independent and symmetrically configured suction heads, achieves simultaneous adsorption of multiple target objects, effectively improving work efficiency and operational stability. The suction cup body adopts a corrugated structure design combined with a flexible sealing lip at the bottom, ensuring good airtightness and adsorption reliability even when facing irregular or slightly uneven surfaces. A rigid connecting plate firmly connects the two suction heads, not only ensuring their synchronization and coordination during operation but also improving the mechanical strength and durability of the overall structure. The air chamber, as the core component for centralized air supply and control, along with multiple connection ports equipped with metal connecting nuts and sealing components, enables flexible access to multiple air lines. Efficient management, along with the black flexible tubing and adjustable connecting screws, enhances the suction cup's adaptability and operational flexibility in complex working environments. The parameter display screen and integrated internal sensors allow operators to obtain real-time suction status information, improving the equipment's intelligence and operational safety. The protective frame and curved handle design not only effectively protect the internal structure but also optimize the human-machine interface, making operation more comfortable and safer. The hollowed-out triangular groove design achieves structural lightweighting, improving overall flexibility while maintaining strength. The pressure relief valve allows for rapid release of internal pressure in emergencies, preventing equipment damage or operational risks. Attached Figure Description

[0022] In this embodiment, a parameter display screen 1 is provided on the top surface of the air chamber 3, and an integrated sensor 13 is provided inside the suction cup body 10. The integrated sensor 13 works in conjunction with the parameter display screen 1.

[0023] In this embodiment, a protective frame 2 is provided above the air chamber 3. The bottom of the protective frame 2 is connected to the top of the rigid connecting plate 9. An arc-shaped handle 4 is provided at the center of the top of the protective frame 2, and the arc-shaped handle 4 is coated with an anti-slip coating.

The arc-shaped handle 4 is ergonomically designed, making it easy for the operator to grip and apply force, thus improving operating comfort.

[0024] In this embodiment, the rigid connecting plate 9 is provided with two hollow triangular grooves 7, which are correspondingly arranged. The hollow triangular groove 7 design helps to reduce the overall structural weight, achieving lightweighting while ensuring strength; structural optimization improves the overall flexibility and ease of operation; it also helps to improve the airflow characteristics or heat dissipation performance of the structure (depending on the specific application), enhancing the user experience.

The wear-resistant coating significantly improves the surface wear resistance of the suction cup body 10 and extends its service life; the coating material has good corrosion resistance and chemical stability, making the suction cup suitable for various complex or harsh working environments; it improves the performance stability of the suction cup during long-term use and reduces the frequency of maintenance and replacement.

[0027] The implementation principle of this embodiment is as follows:

[0028] Initial connections and gas path layout:

[0029] Before use, connect the multiple connection ports 14 on the air chamber 3 to an external air supply device (such as a vacuum pump or air source control system) via the black flexible tubing 8. The metal connecting nut 5 and the sealing component 6 ensure a secure connection and good airtightness. The adjustable connecting screw 12 is used to pre-adjust the contact pressure or relative position between the suction cup body 10 and the target object to accommodate objects of different shapes and sizes.

[0030] Adsorption start-up:

[0031] When the external air source starts working and delivers negative pressure airflow into the air chamber 3, the airflow is quickly transmitted to the inside of the two suction cup bodies 10 through the connection port 14, causing the air pressure inside the suction cups to drop rapidly and creating a negative pressure environment. At this time, due to the action of external atmospheric pressure, the suction cup bodies 10 are tightly attached to the surface of the target object, and the corrugated structure and flexible sealing lip further enhance the sealing effect, ensuring a firm adsorption.

[0032] Status monitoring and feedback:

[0033] The sensor integrated inside the suction cup body 10 monitors the adsorption status in real time, such as changes in air pressure and the strength of adsorption force, and transmits the data to the parameter display screen 1 on the top of the air chamber 3 for real-time display. Operators can observe the display screen to understand the current adsorption status, determine whether there is air leakage, unstable adsorption, or other abnormalities, and make timely adjustments.

[0034] Structural coordination during operation:

[0035] The rigid connecting plate 9 ensures that the two suction heads maintain a stable relative position during operation, preventing misalignment of the suction cups or imbalance of suction force due to external forces. The protective frame 2 and the arc-shaped handle 4 provide protection and convenient operation support for the entire structure, allowing operators to perform gripping and moving operations safely and comfortably.

[0036] Emergency depressurization and adjustment:

[0037] When it is necessary to release the adsorption state or deal with emergencies, the internal air pressure can be quickly released through the pressure relief valve 11 on one side of the outer wall of the air chamber 3, so that the suction cup returns to normal pressure and can be safely detached from the target object. At the same time, the adjustable connecting screw 12 can be finely adjusted as needed during operation to adapt to surface changes or optimize the adsorption effect.
