Description

Technical Field

[0001] The utility model relates to the technical field of flexible grippers, and particularly relates to a flexible gripper combination with anti - detachment function. Background Art

[0002] A flexible gripper is an innovative automated grasping tool, characterized by its soft pneumatic "fingers" that can adaptively wrap around the target object. This design gives the flexible gripper significant advantages when grasping fragile, easily scratched, or irregularly shaped objects. The flexible gripper has been widely used in the field of industrial automation due to its unique advantages, especially showing great potential in fine - operation scenarios in industries such as food, daily chemicals, medical, and fresh produce.

[0003] Industrial production requires the use of flexible grippers. Existing flexible grippers usually use two rubber pads for clamping. This method is not easy to control the clamping force. If the force is too large, it is easy to damage the parts; if it is too small, the clamping is not tight, reducing the use efficiency. At the same time, for curved - surface parts, only a single point can be clamped, greatly reducing the production efficiency of the parts.

[0004] Therefore, it is necessary to design and transform the flexible gripper to effectively prevent the situation where existing flexible grippers usually use two rubber pads for clamping. There is a metal device outside the rubber pads. This method is not easy to control the clamping force. If the force is too large, it is easy to damage the parts; if it is too small, the clamping is not tight, reducing the use efficiency. At the same time, for curved - surface parts, only a single point can be clamped, greatly reducing the production efficiency of the parts. Summary of the Utility Model

[0005] The utility model provides a flexible gripper combination with anti - detachment function to prevent the problem of skew and detachment of the flexible gripper during use.

[0006] To solve the above - mentioned technical problems, the technical solution of the utility model is as follows:

[0007] An embodiment of the utility model provides a flexible gripper combination with anti - detachment function, including:

[0008] A flexible gripper, the flexible gripper includes a first end and a second end, and the first end is provided with a claw - center surface and a reserved surface;

[0009] A raised ring is annularly arranged on the outer surface of the first end, and a circular ring is clamped outside the raised ring;

[0010] In the use state, the elastic modulus of the inner side and the outer side of the flexible gripper is different. When positive pressure is provided, the second end of the flexible gripper opens outward; when negative pressure is provided, the claw - center surface and the reserved surface contract inward to clamp the second end.

[0011] Further, a connection joint is provided at the first end of the flexible jaw. The connection joint is hollow inside and is used to connect positive and negative pressures.

[0012] Further, an arc-shaped groove is provided on the inner surface of the ring, and the arc-shaped groove is matched with the raised ring.

[0013] In the use state, the arc-shaped groove is clamped with the raised ring.

[0014] Further, a hard rod is connected to the end of the connection joint away from the flexible jaw.

[0015] The end of the connection joint away from the flexible jaw is provided with an external thread, and one end of the hard rod is provided with an internal thread that is matched with the external thread.

[0016] Further, the other end of the hard rod is connected to a pneumatic joint. The hard rod is hollow inside, and the hard rod is connected to a trachea through the pneumatic joint.

[0017] Further, a buffer tube is connected to the end of the connection joint away from the flexible jaw.

[0018] One end of the buffer tube is provided with an internal thread that is matched with the external thread.

[0019] Further, a compression spring is provided inside the buffer tube.

[0020] Further, a guide groove and a slider are provided inside the buffer tube.

[0021] In the use state, the slider makes a sliding movement in the guide groove and is restricted from rotating in the circumferential direction.

[0022] Further, an end cap is provided at the other end of the buffer tube. A hole is opened on the end cap, and the hole is connected to an air circuit.

[0023] Further, the buffer tube is connected to a pneumatic joint through the end cap, and the pneumatic joint is connected to a trachea.

[0024] In the use state, the pneumatic joint intakes air through the trachea to provide positive pressure and negative pressure.

[0025] Further, the connection joint is connected to a side connection joint. The side connection joint is hollow inside and is connected to an air circuit.

[0026] The above solution of the present utility model has at least the following beneficial effects:

[0027] In the present utility model, the flexible gripper is ventilated. Through the action of the buffer tube and the compression spring, the stability of the clamping of components is protected efficiently with buffering. At the same time, the flexible gripper is fixed by the raised ring and the arc-shaped groove. By introducing positive pressure and negative pressure into the flexible gripper, the flexible gripper can effectively clamp and open, which is convenient for the user. At the same time, the connection joint is rigidly connected to the buffer inner tube, the buffer outer tube, the end cover, and the pneumatic joint, so that the connection is more stable and convenient for the user to use;

[0028] In the flexible gripper of the present utility model, the opposite sides of the gripper have reserved surfaces. By shrinking inwards through the reserved surfaces, a larger scaling space can be provided for the flexible gripper, thereby increasing the negative pressure deformation amount and enhancing the clamping stability of the flexible gripper for the material. At the same time, the circular ring can prevent the flexible gripper from shaking in the horizontal direction during operation, further improving the stability of the flexible gripper during use.

When positive pressure is provided, the second end 12 of the flexible jaw 1 opens outward. When negative pressure is provided, the jaw center surface 15 and the reserved surface 14 contract inward to clamp the second end 12.

[0042] In the embodiment of the present utility model, through the arrangement of the convex ring and the circular ring, it is convenient to clamp the flexible gripper, making the flexible gripper more compact and stable during installation, facilitating the user to use. The second end 12 of the flexible gripper is made of soft rubber; there is a cavity inside the flexible gripper 1, and the elastic modulus of the inner and outer sides of the flexible gripper 1 is different. When positive pressure is provided, the flexible gripper 1 opens outward, and when negative pressure is provided, it contracts inward. Through the adjustment of positive pressure and negative pressure, it is convenient to quickly clamp and open the starting gripper, facilitating the user to use; a claw center surface 15 is provided at the center of the first end 11, and reserved surfaces 14 are provided on both sides of the first end 11, and the two reserved surfaces 14 and the claw center surface 15 are in the same plane, so as to provide a larger scaling space for the flexible gripper 1, further improving the clamping stability of the flexible gripper 1 for the material and increasing the opening angle of the flexible gripper 1; the design of the flexible gripper combines the structure of the reserved surface and the circular ring, which can effectively prevent the clamped material from slipping during the operation. This anti-slip design enhances the overall safety and reduces the risk of material loss; the design of the reserved surface 14 enables the flexible gripper to have a larger scaling space during the working process, not only improving the stability of the gripper for the material, but also increasing the opening angle of the gripper, and can better adapt to materials of different shapes and sizes; since the flexible gripper is made of flexible material, it can absorb a certain amount of impact force during the clamping process, playing a role in shock absorption and buffering, and can effectively avoid damage to the material during the clamping process; the combined design of the convex ring and the circular ring prevents the gripper from tilting or falling off when subjected to a lateral force, making the installation of the flexible gripper more compact and stable, and increasing the stability.

[0043] As Figures 1 to 2 shown, a connection joint 5 is provided at the first end 11 of the flexible gripper 1. The connection joint 5 is hollow inside and is used to connect positive and negative pressures.

[0044] In the embodiment of the present utility model, a connection joint 5 is provided at the first end 11 of the flexible jaw 1. The connection joint 5 is connected to the flexible jaw 1 through the first end 11, forming a channel for the adjustment of positive pressure and negative pressure, enabling the jaw to quickly and flexibly respond to air pressure changes during operation and realizing the functions of clamping and releasing; the setting of the connection joint 5 enables the air source to be connected to the flexible jaw, facilitating the regulation of the air pressure inside the jaw; the connection between the connection joint 5 and the jaw can provide additional support and stability, ensuring that the jaw maintains good structural strength during operation and reducing the risk of jaw displacement and jaw detachment caused by operation or external forces; the design of the connection joint 5 facilitates the maintenance and replacement of the flexible jaw. When it is necessary to clean or replace the jaw, the jaw is disassembled from the connection joint 5, simplifying the maintenance process and improving the convenience of use; through the combination of the connection joint 5 and the jaw, it can ensure that the jaw always maintains a stable air pressure state during operation, reducing the risk of the clamped material falling off during operation and enhancing the overall safety.

[0046] In the use state, the arc-shaped groove 41 is clamped with the raised ring 2.

[0047] In the embodiment of the present utility model, the arc-shaped groove 41 and the ring 3 are used in combination. The arc-shaped groove 41 is closely attached to the raised ring 2, thereby effectively improving the stability of the flexible jaw 1. At the same time, the setting of the ring 3 can prevent the flexible jaw 1 from shaking in the horizontal direction during operation; the tight clamping between the arc-shaped groove 41 and the raised ring 2 enhances the stability of the flexible jaw 1, enabling the jaw to firmly maintain its position during operation and avoiding displacement caused by external forces or vibrations, thereby ensuring the effectiveness of the jaw when clamping an object; the setting of the ring 3 effectively prevents the flexible jaw 1 from shaking in the horizontal direction. The ring provides additional support and rigidity, enabling the jaw to maintain a good state during operation and reducing the risk of unstable clamping or clamping failure that may be caused by shaking.

[0048] As Figures 1 to 2 shown, a rigid rod 7 is connected to the end of the connection joint 5 far from the flexible jaw 1;

[0049] The end of the connection joint 5 far from the flexible jaw 1 is provided with an external thread, and one end of the rigid rod 7 is provided with an internal thread that matches the external thread.

[0050] In the embodiment of the present utility model, the distal end of the connecting joint 5 is provided with an external thread, while one end of the rigid rod 7 is provided with a matching internal thread, so that the rigid rod 7 is threadedly connected to the connecting joint 5; by tightening or loosening the rigid rod, the fastening or disassembly of the connection can be realized, which facilitates the assembly, maintenance and replacement of the equipment; the threaded connection can bear axial force and torsional force, so that the connecting joint 5 and the rigid rod 7 are not easily loosened during the working process, ensuring the stability and safety of the whole system, which is particularly important for application occasions that need to bear dynamic loads or external impacts. The rigid rod 7 ensures that when the object is clamped, the clamping jaws can be positioned with high precision, thereby effectively reducing the grasping error and ensuring the stability of the object; the clamping jaws adopt an anti-detachment structure, effectively preventing the object from falling off during the operation, increasing the safety and reliability of the grasping; the flexible clamping jaws can adapt to objects of different shapes and sizes, enhancing the flexibility of the system and enabling it to handle various complex grasping tasks; the high-precision rigid connection ensures the stability of the clamping jaws during the operation, reducing the error caused by mechanical loosening and improving the overall performance.

[0051] As Figures 1 to 2 shown, the other end of the rigid rod 7 is connected with a pneumatic joint 8. The rigid rod 7 is hollow inside, and the rigid rod 7 is connected to the air pipe through the pneumatic joint 8.

[0052] In the embodiment of the present utility model, one end of the rigid rod 7 is connected with a pneumatic joint 8, and the pneumatic joint 8 is connected to the air pipe; the pneumatic joint 8 is used for positive and negative pressure to enter the rigid rod through the air pipe, so as to realize the driving and control of the clamping jaws by positive and negative pressure air. The pneumatic transmission method can provide powerful power and is suitable for application scenarios that require high efficiency and fast response; the pneumatic joint 8 enables the rigid rod 7 to be conveniently connected to the air source, facilitating quick installation and disassembly in different working environments, enabling the equipment to quickly switch between different working occasions according to needs, and improving the adaptability of the equipment; the pneumatic system has high efficiency in power transmission and can realize fast actions. When clamping and releasing objects, the pneumatic system can complete the actions in a short time, thereby improving the working efficiency; the pneumatic joint 8 has good sealing performance, reducing the risk of gas leakage and improving the safety of the system. At the same time, the characteristics of pneumatic drive enable the equipment to stop safely through the characteristics of the pneumatic system when encountering overload or failure.

[0053] Working principle: Connect the positive and negative pressure air supply equipment through pneumatic connectors to supply air to the flexible gripper 1. Utilize the function of the rigid rod 7. With the positive pressure provided by the pneumatic connector 8, the flexible gripper 1 can be expanded, enabling the flexible gripper 1 to enter the stage of preparing for clamping. At this time, with the negative pressure provided by the pneumatic connector 8, the flexible gripper 1 contracts, thereby achieving the clamping of the material. Meanwhile, the raised ring 2 and the arc-shaped groove 41 can fix the flexible gripper 1, so as to provide positive or negative pressure inside the flexible gripper 1, enabling the flexible gripper 1 to effectively open and clamp, thus facilitating the user to use.

[0054] In Embodiment 2 of the present utility model, as Figures 3 to 4 shown, one end of the connecting joint 5 far from the flexible gripper 1 is connected with a buffer tube 6;

[0055] One end of the buffer tube 6 is provided with an internal thread matching the external thread.

[0056] In an embodiment of the present utility model, the buffer tube 6 can prevent impact and damage to the workpiece during the process of gripping the workpiece, protect the workpiece from excessive force or impact. By connecting the buffer tube 6 and the connecting joint 5 through internal and external threads, loosening caused by vibration or external force during the working process is prevented, ensuring the stability and reliability of the system; the buffer tube can help disperse the load. When the gripper grips heavy objects or performs rapid actions, it can reduce the direct impact on the connecting joint 5 and other components, thereby reducing the stress concentration of the overall structure; the inside of the buffer inner tube 6 is connected to the connecting joint 5 through a through connecting rod; the setting of the rigid connecting rod inside the buffer tube 6 provides additional support and rigidity, making the connection between the buffer tube and the connecting joint 5 more firm, and can effectively prevent deformation under high load or dynamic movement, ensuring the reliability of the entire system; through the rigid connecting rod, the connection between the buffer tube 6 and the connecting joint 5 becomes simpler and more direct. When performing equipment inspection or replacement, this connection can be handled more conveniently, reducing the complexity of disassembly and installation; through the design of the rigid connecting rod, the overall structure is more compact and stable, and can improve the performance of the equipment under high speed or high load.

[0057] As Figures 3 to 4 shown, a compression spring 61 is arranged inside the buffer tube 6.

[0058] In an embodiment of the present utility model, through the setting of the compression spring, the buffer tube can be buffered, thereby better protecting the components, and improving the stability and safety of the clamping of the components; the compression spring 8 is convenient for converting the impact force received by the flexible gripper 1 into the kinetic energy of the compression spring 8 and resetting through expansion.

[0059] As Figures 3 to 4 shown, a guide groove 62 and a slider 63 are arranged inside the buffer tube 6;

[0060] In the use state, the slider 63 slides in the guide groove 62, and the rotation of the slider 63 in the circumferential direction is restricted.

[0061] In the embodiment of the present utility model, through the arrangement of the guide groove and the slider, the detachment of the buffer tube is prevented, the safety of the buffer tube is improved, and it is convenient for the user to use; the guide groove 62 provides a safe sliding path for the slider 63, avoiding direct contact between the slider and the inner wall of the buffer tube during the working process, reducing the risk of wear and damage, and thus extending the service life of the buffer tube; the slider 63 slides in the guide groove 62, enabling efficient dynamic response. When the system is subjected to external force or pressure, the slider adjusts in the guide groove 62; the slider 63 can provide the necessary clamping force during the sliding process to ensure the firm connection of the components inside the buffer tube. The provision of the clamping force helps to ensure the stability of the system in both dynamic and static states and prevent the loosening of the components; by restricting the slider 63 within the guide groove 62, the detachment or displacement of the slider in case of an accident is avoided, thereby improving the safety of the device.

[0062] As Figures 3 to 4 shown, the other end of the buffer tube 6 is provided with an end cap 64, and a hole is opened on the end cap 64, and the hole is connected to the gas path.

[0063] In the embodiment of the present utility model, through the arrangement of the end cap, it is convenient to make the compression spring press tightly, thereby improving the buffering effect of the flexible jaw, ensuring that the compression spring always maintains a certain preload during the working process, and thus improving the elasticity and buffering capacity of the compression spring; through the end cap 64, the compression spring can better absorb and release the externally applied force. When the jaw clamps or releases an object, the buffering function of the compression spring can effectively reduce the impact force, thereby reducing the risk of damage to the jaw and other components and extending the service life of the device; the end cap 64 ensures the stability and consistency of the compression spring, making the reaction of the jaw more stable during the operation process and preventing the clamping error caused by instability; by fixing the compression spring in place through the end cap 64, the accidental displacement or detachment of the compression spring under high load or rapid movement conditions can be prevented, improving the safety of the device and reducing the risk of accidents that may occur during the operation process.

[0064] As Figures 3 to 4 shown, the buffer tube 6 is connected with a pneumatic joint 8 through the end cap 64, and the pneumatic joint 8 is communicated with the air pipe;

[0065] In the use state, the pneumatic joint 8 intakes air through the air pipe to provide positive pressure and negative pressure.

The positive pressure is used to clamp the object, while the negative pressure is used to release the object, making the gripper more adaptable when dealing with different types of objects; through the positive pressure provided by the pneumatic joint 8, the flexible gripper can clamp the object more tightly, ensuring that the object will not slide or fall off during the operation, which helps to improve production efficiency and safety; the connection between the pneumatic joint 8 and the air tube makes the installation and maintenance of the system more convenient. The air tube can be quickly connected or disconnected, facilitating inspection, maintenance and replacement, reducing the downtime of the equipment; through the pneumatic control provided by the pneumatic joint 8, the equipment can achieve more stable clamping and releasing actions during operation, thus reducing the risk of accidents caused by improper operation.

[0067] Working principle: Connect the positive and negative pressure air supply equipment through the pneumatic joint to ventilate the flexible gripper 1. Utilize the functions of the buffer tube 6 and the compression spring 61 to buffer and efficiently protect the stability of the component clamping. Through the positive pressure provided by the pneumatic joint 8, the flexible gripper 1 can be expanded to enter the stage of preparing to clamp. At this time, through the negative pressure provided by the pneumatic joint 8, the flexible gripper 1 contracts, thereby realizing the clamping of the material. At the same time, the convex ring 2 and the arc-shaped groove 41 can fix the flexible gripper 1. By providing positive pressure or negative pressure inside the flexible gripper 1, the flexible gripper 1 can be effectively opened and clamped, facilitating the user to use.

[0068] In the second embodiment of the present utility model, as Figures 5 to 6 shown, the connection joint 5 is connected with a side connection joint 9, and the side connection joint 9 is hollow inside and connected with an air path.

[0069] In the embodiment of the present utility model. The connection joint 5 is connected with the positive and negative pressure equipment through the side connection joint 9, and the side connection joint provides a channel for the air path; the connection between the connection joint 5 and the side connection joint 9 can adapt to different installation spaces and equipment requirements; through the side connection joint 9, gas can be transmitted to the gripper; the connection joint 5 and the side connection joint 9 ensure the stable connection of the air path, reducing the possibility of gas leakage, so that the pneumatic system maintains good pressure and performance during operation, the system failure rate is reduced, the need for maintenance and repair is reduced, and thus the overall maintenance cost is reduced.

[0070] Working principle: Connect the positive and negative pressure air supply equipment through the side joint 9 to directly supply air to the flexible gripper 1. The buffer rod 6 or the rigid rod 7 is connected to the connection joint 5, making it more convenient to replace the buffer rod 6 and the rigid rod 7. Through the positive pressure provided by the side joint 9, the flexible gripper 1 can be expanded, enabling the flexible gripper 1 to enter the stage of preparing for clamping. At this time, through the negative pressure provided by the pneumatic joint 8, the flexible gripper 1 contracts, thereby realizing the clamping of the material.
