[0057] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0058] It should be noted that when a component is said to be "connected" to another component, it can be directly connected to the other component or it can be connected to a component in between. When a component is said to be "set on" another component, it can be directly set on the other component or it may be set to a component in between.

[0059] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0060] like Figures 1 to 15As shown, this application provides a clamping device 100 for clamping objects. The clamping device 100 includes a base 10 and two clamping arms 20, each clamping arm 20 being rotatably connected to the base 10. The clamping device 100 also includes a support frame 30 and a flexible member 40. The support frame 30 is mounted on at least one of the two clamping arms 20. The flexible member 40 is mounted on the support frame 30 and can contact the object. When the two clamping arms 20 clamp the object, the flexible member 40 contacts the object and can deform, increasing the contact area and reducing the pressure, thereby reducing damage to the clamped object while ensuring stable clamping. In addition, the flexible member 40 can achieve a buffering and shock absorption effect when in contact with the object. The two clamping arms 20 include a first clamping arm 24 and a second clamping arm 25; the number of support frames 30 is one or two, and the number of flexible members 40 corresponds to the number of support frames 30. When there is one support frame 30, it is installed on either the first clamping arm 24 or the second clamping arm 25, and there is one flexible member 40, which is installed on the support frame 30. When there are two support frames 30, they are a first support frame 37 and a second support frame 38. The first support frame 37 is installed on the first clamping arm 24, and the second support frame 38 is installed on the second clamping arm 25. There are two flexible members 40, a first flexible member 44 and a second flexible member 45. The first flexible member 44 is installed on the first support frame 37, and the second flexible member 45 is installed on the second support frame 38. When the clamping device 100 clamps an object, the first flexible member 44 and the second flexible member 45 respectively contact the two sides of the object. The support frame 30 is detachably installed on at least one of the two clamping arms 20, facilitating the installation and removal of the support member 30; the support frame 30 is also movably installed on at least one of the two clamping arms 20, facilitating the adjustment of the position of the flexible member 40 on the clamping arm 20.

[0061] In this embodiment, as Figures 1 to 2 as well as Figure 10 and Figure 11 As shown, the base 10 is rod-shaped and has a length direction in space. Along the length direction of the base 10, its end has a mounting groove 11. Parts of the two clamping arms 20 are located within the mounting groove 11 and are rotatably connected to the base 10 via a rotating pin 12. Specifically, the first clamping arm 24 has a first shaft hole, the second clamping arm 25 has a second shaft hole, one end of the rotating pin 12 is connected to the base 10, and the other end passes through the first shaft hole and the second shaft hole and is connected to the base 10. Of course, in other embodiments, the base 10 can also have other structures, which will not be further described here.

[0062] In this embodiment, as Figures 1 to 4 as well as Figures 10 to 13As shown, the clamping arm 20 is generally rod-shaped and has a length direction in space; the length direction of the clamping arm 20 is parallel to its extension direction. The extension direction of the first clamping arm 24 is parallel to or at an angle to the extension direction of the second clamping arm 25; during the process of clamping an object, the angle between the extension direction of the first clamping arm 24 and the extension direction of the second clamping arm 25 gradually decreases until the two clamping arms 20 clamp the object.

[0063] In this embodiment, as Figures 1 to 4 as well as Figures 10 to 13As shown, the clamping arm 20 can be a single integrated structure, which reduces the manufacturing difficulty of the clamping arm 20 and strengthens its structural strength. For example, the clamping arm 20 can be a single rod. Of course, in other embodiments, at least one clamping arm 20 may also include at least two unit arms; for example, the clamping arm 20 includes a first unit arm 22 and a second unit arm 23. The first unit arm 22 is rotatably connected to the base 10; the second unit arm 23 is slidably connected to the first unit arm 22. The arrangement of the first unit arm 22 and the second unit arm 23 can extend the length of the clamping arm 20, adapting to the support needs of different objects. The clamping arm 20 also includes a driving component 60, which can drive the second unit arm 23 to slide along the first unit arm 22, achieving the effect of length adjustment of the clamping arm 20. The drive assembly 60 is mainly used to drive the second unit arm 23 to slide along the first unit arm 22. To achieve its basic function, a motor, cylinder, hydraulic cylinder, or even a manually driven component can be selected from existing technologies. When the motion mode directly output by the drive assembly 60 is inconsistent with the motion mode of the second unit arm 23, an appropriate transmission component can be used to convert and transmit the motion mode. The drive assembly 60 includes a drive member 63, a drive rack 61, and a drive gear 62. The drive rack 61 is installed on one of the first unit arm 22 and the second unit arm 23; the drive gear 62 is rotatably installed on the other of the first unit arm 22 and the second unit arm 23, and the drive gear 62 meshes with the drive rack 61; the drive member 63 is linked to the drive gear 62, and the drive member 63 can drive the drive gear 62 to rotate. A drive component 63 is mounted on the first unit arm 22, and a drive gear 62 is rotatably mounted on the first unit arm 22. The drive component 63 and the drive gear 62 are connected in a transmission manner. A drive rack 61 is mounted on the second unit arm 23, and the drive gear 62 meshes with the drive rack 61. The drive component 63 drives the drive gear 62 to rotate, and the drive gear 62 can drive the drive rack 61 to move along the length direction of the clamping arm 20, thereby driving the second unit arm 23 to move along the length direction of the clamping arm, thus adjusting the length of the clamping arm. The drive component 63 drives the drive gear 62 via a transmission belt 64. The drive component 63 has an output shaft 631, and the drive gear 62 is rotatably mounted on the first unit arm 22 via a rotating shaft 65. The transmission belt 64 is wound around the output shaft 631 and the rotating shaft 65. The drive component 63 can synchronously drive the drive gear 62 to rotate via the transmission belt 64. The first unit arm 22 has a sliding groove 221 for the second unit arm 23 to slide, and the sliding groove 221 can limit the movement of the second unit arm 23. Preferably, the drive element 63 is a motor; for example, the drive element 63 is a servo motor.

[0064] In this embodiment, as Figures 5 to 9 as well as Figures 14 to 15As shown, the shape of the flexible member 40 is not strictly limited; for example, the flexible member 40 can be plate-shaped or block-shaped. The flexible member 40 includes a mating surface 41, which has a first recessed area 42. The mating surface 41 can contact an object, which is beneficial for the flexible member 40 to contact the object. Specifically, the first flexible member 44 includes a first mating surface 411, and the second flexible member 45 includes a second mating surface 412. When the first flexible member 44 and the second flexible member 45 are in contact, the first mating surface 411 faces the second mating surface 412, and the first mating surface 411 contacts the second mating surface 412. Both the first flexible member 44 and the second flexible member 45 are provided with a first recessed area 42. When the first flexible member 44 and the second flexible member 45 are in contact, the first mating surface 411 is recessed away from the second mating surface 412 to form the first recessed area 42, and the second mating surface 412 is recessed away from the first mating surface 411 to form the first recessed area 42. The first recessed area 42 helps to increase the contact area between the flexible member 40 and the object with an irregular curved surface, and can reduce the pressure exerted by the flexible member 40 on the object. The first mating surface 411 and the second mating surface 412 are both continuous curved surface structures; the flexible member 40 is made of rubber. The first recessed area 42 extends along the length direction of the clamping arm 20; the first mating surface 411 also includes a first contact area 413 and a second contact area 414; along the length direction perpendicular to the clamping arm 20, the first contact area 413, the first recessed area 42, and the second contact area 414 are arranged sequentially. When the flexible member 40 is not subjected to external force, the contact area between the first contact area 413 and the object is A0, and the contact area between the second contact area 414 and the object is A0. When the flexible member 40 is subjected to a force in the direction of the object, the flexible member 40 deforms, and the contact areas between the first contact area 413 and the object and the second contact area 414 and the object change, thereby reducing the pressure on the object being held. For example, the contact area between the first contact area 413 and the object is A, and the contact area between the second contact area 414 and the object is A; A is greater than A0.

[0065] In another embodiment, such as Figure 3 and Figure 4As shown, at least one flexible element 40 has a cavity (not shown). The clamping device 100 also includes an air supply pipe 50 connected to the flexible element 40. The pipe of the air supply pipe 50 communicates with the cavity, allowing gas to be delivered into the cavity to change the stiffness of the flexible element 40 to accommodate different objects. The cavity is located in the first flexible element 44 and / or the second flexible element 45, selected according to actual needs, and will not be elaborated here. One end of the air supply pipe 50 is connected to a pump (not shown). The pump can be integrated into the first unit arm 22, the second unit arm 23, or the base 10, or it can be located outside the clamping device 100. The air supply pipe 50 is a flexible pipe that moves with the second unit arm 23 when the second unit arm 23 moves along the first unit arm 22. By changing the gas in the cavity, the air supply pipe 50 can adjust the pressure of the cavity; an increase or decrease in the pressure in the cavity can affect the stiffness of the flexible element 40.

[0066] In this embodiment, as Figures 5 to 9 as well as Figures 14 to 15 As shown, the support frame 30 has a second recessed area 31 on the side facing the flexible member 40. The second recessed area 31 can accommodate the flexible member 40, absorb the deformation of the flexible member 40, and increase the required thickness of the flexible member 40. With respect to the support frame 30 and the flexible member 40 mounted on the support frame 30, the support frame 30 is recessed away from the flexible member 40 to form the second recessed area 31. The second recessed area 31 corresponds to the position of the first recessed area 42, increasing the thickness of the flexible member 40 located in the first recessed area 42. The clamping arm 20 has a first slot 21, and the support frame 30 has a first locking block 32. The first locking block 32 cooperates with the first slot 21 to fix the support frame 30 to the clamping arm 20. The first slot 21 extends along the length of the clamping arm 20, and the first slot 21 has an opening at the end of the second unit arm 23 facing away from and / or towards the first unit arm 22. The first locking block 32 of the support frame 30 enters the first slot 21 through the opening of the first slot 21. Of course, in other embodiments, the support frame 30 has a first slot 21, the clamping arm 20 has a first locking block 32, and the first locking block 32 cooperates with the first slot 21.

[0067] In this embodiment, as Figures 5 to 9 as well as Figures 14 to 15As shown, the support frame 30 has a second locking block 33, and the flexible member 40 has a second locking groove 43. The second locking block 33 and the second locking groove 43 cooperate to fix the flexible member 40 to the support frame 30. There are two second locking grooves 43, which are located on opposite sides of the flexible member 40. There are also two second locking blocks 33, which are located on opposite sides of the flexible member 40, and each second locking block 33 cooperates with its corresponding second locking groove 43. The second locking groove 43 extends along the length of the clamping arm 20, and has an opening at the end of the flexible member 40 facing away from and / or towards the first unit arm 22 to facilitate the connection between the flexible member 40 and the support frame 30. Of course, in other embodiments, the flexible member 40 has a second locking block 33, and the support frame 30 has a second locking groove 43. The second locking block 33 and the second locking groove 43 cooperate to fix the flexible member 40 to the support frame 30. Alternatively, one of the support frame 30 and the flexible member 40 may have a first hook and loop fastener, and the other may have a second hook and loop fastener that cooperates with the first hook and loop fastener, so as to fix the flexible member 40 and the support frame 30.

[0068] In this embodiment, as Figures 1 to 15As shown, the support frame 30 is an integral structure made of rubber material and has a certain degree of flexibility. Of course, in other embodiments, the support frame 30 can also be a split structure, comprising multiple components. The support frame 30 includes support members 34 and connecting members 35. There are multiple support members 34, each movably mounted on the clamping arm 20. Along the extending direction of the clamping arm 20, the support members 34 are spaced apart, and the flexible member 40 is connected to the support members 34. Along the extending direction of the clamping arm 20, at least one connecting member 35 is provided between adjacent support members 34, and the connecting members 35 between adjacent support members 34 are arranged sequentially along the extending direction of the clamping arm 20. By changing the number and / or position of the support members 34 and the connectors 35, the deformation and stiffness of the flexible member 40 can be affected, thereby improving the elasticity and viscoelasticity of the flexible member 40. This allows it to quickly recover its deformation under large deformations and also enables it to generate hysteresis loss under vibration and alternating stress, reducing energy loss. This effectively reduces damage to soft and fragile objects during clamping by the clamping device 100 and adapts to the needs of different application scenarios. Along the length of the clamping arm 20, both the connectors 35 and the support members 34 have a certain length. The number of connectors 35 between adjacent support members 34 can be changed, altering the distance between adjacent support members 34. Changing the number of connectors 35 between adjacent support members 34 along the length of the clamping arm 20 changes the distance between the contact points of each support member 34 and the flexible member 40 along the length of the clamping arm 20, thus altering the deformation and stiffness of the flexible member 40. For example, along the length of the clamping arm 20, the number of connecting pieces 35 between two adjacent support members 34 is one, two, or more than three. The support frame 30 also includes two buckles 39, which are respectively engaged with the support members 34. The two buckles 39 are located on opposite sides of the clamping arm 20, and are either fitted or loosely fitted with the clamping arm 20. The side of the buckle 39 facing the flexible member 40 and the side of the clamping arm 20 facing the flexible member 40 form a second recessed area 31, which connects the buckle 39 to the flexible member 40 and facilitates the connection between the flexible member 40 and the support member 34. The flexible member 40 has first Velcro on both sides, and both buckles 39 have second Velcro. The first Velcro and the second Velcro cooperate to fix the flexible member 40 to the buckles 39. The connector 35 has a third locking block 351 that engages with the first locking slot 21; the support member 34 has a fourth locking block 341 that engages with the first locking slot 21, so as to fix the support member 34 and the connector 35 to the second unit arm 23. The connector 35 is a magnetic component, and at least a portion of the support member 34 is made of ferromagnetic material. The support member 34 can be attracted and fixed to the connector 35, facilitating the assembly and disassembly of the support member 34 and the connector 35.The buckle 39 has a third slot 391, and the support member 34 has a fifth block 342. The fifth block 342 cooperates with the third slot 391 to connect the buckle 39 and the support member 34.

[0069] like Figures 1 to 16 As shown, this application also provides a method for using the clamping device 100, which adopts the clamping device 100 in the above embodiments; the method for using the clamping device 100 includes the following steps:

[0070] S100. Adjust the stiffness of the flexible member 40 according to the object. The pump supplies air to the cavity of the flexible member 40 through the air supply pipe 50, thereby changing the stiffness of the flexible member 40; and / or, adjust the number of support members 34 and connecting members 35 to change the stiffness of the flexible member 40.

[0071] S200: Place the object between the two clamping arms 20; adjust the angle between the extension direction of the first clamping arm 24 and the extension direction of the second clamping arm 25 and / or the length of the first clamping arm 24 and the length of the second clamping arm 25 according to the size of the object. Specifically, rotating the first clamping arm 24 and / or the second clamping arm 25 allows the angle between the extension direction of the first clamping arm 24 and the extension direction of the second clamping arm 25 to be adjusted according to the size of the object; the driving member 63 drives the driving gear 62 through the conveyor belt, the driving gear 62 drives the driving rack 61, and the driving rack 61 drives the second clamping arm 25 to move along the length direction of the clamping arm 20, thereby adjusting the length of the clamping arm 20.

[0072] S300, rotate at least one clamping arm 20 about the base 10 until the flexible member 40 contacts and clamps the object. Rotate the first clamping arm 24 and / or the second clamping arm 25 such that the angle between the extension direction of the first clamping arm 24 and the extension direction of the second clamping arm 25 decreases until both the first clamping arm 24 and the second clamping arm 25 contact the outer wall of the object to clamp the object.

[0073] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0074] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are quite specific and detailed. However, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
