[0064] The technical solutions in 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.

[0065] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. When a component is said to be "set on" another component, it can be directly set on the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0066] 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. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0067] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0068] See Figure 1 and Figure 2 This embodiment provides a clamping device 100 for clamping a target component. The target component can be a lithium-ion battery. In the recycling and processing of lithium-ion batteries, the clamping device 100 clamps the lithium-ion battery to position it on the worktable, thereby facilitating subsequent inspection, processing, and other procedures.

[0069] See further Figure 1 and Figure 2 The clamping device 100 includes a drive assembly 10, a first transmission member 20, a plurality of second transmission members 30, and a plurality of clamping members 40. The first transmission member 20 is driveably connected to the drive assembly 10. The plurality of second transmission members 30 are arranged around the outer periphery of the first transmission member 20, and each of the plurality of second transmission members 30 is driveably engaged with the first transmission member 20. Each clamping member 40 includes two clamping portions 41. The two clamping portions 41 are driveably connected to the corresponding second transmission member 30, and the two clamping portions 41 are configured to move closer to each other to clamp the target member, or to move further apart to release the target member, driven by the second transmission member 30.

[0070] According to the clamping device 100 of this application, the drive assembly 10 can drive a first transmission member 20 to move, thereby driving multiple second transmission members 30 to move, and in turn driving multiple clamping members 40 to simultaneously clamp or release the target member, facilitating the clamping control of the target member. Simultaneously, during the clamping process of the target member, the second transmission member 30 can drive two clamping parts 41 to simultaneously apply forces in opposite directions to the target member, thus ensuring the clamping stability of the target member. Therefore, the clamping device 100 of this application can simultaneously improve both the clamping efficiency and the clamping reliability of the target member.

[0071] In the processing of lithium-ion batteries, the improved clamping efficiency of lithium-ion batteries can further enhance the efficiency of subsequent testing and processing steps.

[0072] In this embodiment, each clamping member 40 clamps one or more corresponding target members. In other embodiments, the clamping device 100 may also consist of a plurality of clamping members 40 jointly clamping one or more target members. In the plurality of clamping members 40 corresponding to a single target member, the relative directions of the two clamping portions 41 of each clamping member 40 intersect each other. For example, the plurality of clamping portions 41 may be arranged in a ring.

[0073] In some embodiments, see Figure 1 and Figure 2 The clamping device 100 includes a mounting member 60. The mounting member 60 includes a first mounting portion 61 and a plurality of second mounting portions 62. A first transmission member 20 and a plurality of second transmission members 30 are movably disposed on the first mounting portion 61. The plurality of second mounting portions 62 are connected to the first mounting portion 61 around it. The second mounting portions 62 are spaced apart from the second transmission members 30. The side of the second mounting portion 62 facing away from the second transmission members 30 is used to support the target member. Each clamping member 40 is movably disposed on the corresponding second mounting portion 62.

[0074] In this way, the second mounting part 62 can provide stable support for the target part, thereby further improving the clamping stability.

[0075] In some embodiments, the second mounting portion 62 has a groove C. The clamping member 40 includes two clamping portions 41 spaced apart. Each clamping portion 41 includes a transmission portion 412 and a clamping section 411. One end of the transmission portion 412 is disposed in the groove C, and the other end of the transmission portion 412 extends out of the groove C and engages with the second transmission member 30. The clamping section 411 is located on the side of the second mounting portion 62 opposite to the second transmission member 30 and is connected to the transmission portion 412. The groove C can guide the movement of the clamping portion 41, thereby improving the movement accuracy of the clamping portion 41 and ensuring the clamping stability of the clamping portion 41 on the target part.

[0076] Optionally, the clamping section 411 is provided with an arc-shaped groove, which protrudes in a direction away from the other clamping section 411. When clamping a cuboid lithium-ion battery, the two ends of the clamping section 411 along its circumference can respectively abut against the side of the lithium-ion battery, thereby achieving clamping of the lithium-ion battery. When clamping a cylindrical lithium-ion battery, the side of the lithium-ion battery can be roughly adapted to the arc-shaped groove. Therefore, the clamping section 411 can improve the applicability of the clamping device 100.

[0077] In some embodiments, see Figure 2 and Figure 3 The mounting component 60 also includes a plurality of third mounting portions 63. The third mounting portions 63 surround the periphery of the first mounting portion 61, and each third mounting portion 63 corresponds to a second mounting portion 62. The second transmission member 30 is movably disposed on the third mounting portion 63. This facilitates the transmission engagement between the second transmission member 30 and the corresponding clamping member 40.

[0078] Optionally, a plurality of third mounting portions 63 surround the periphery of the second portion 612.

[0079] In some implementations, see Figure 3 The first mounting portion 61 includes a first part 611 and a second part 612. A plurality of second mounting portions 62 surround and connect to the periphery of the first part 611. The second part 612 connects to one side of the first part 611 along its thickness direction. A plurality of third mounting portions 63 surround and connect to the periphery of the second part 612.

[0080] In some embodiments, see Figure 2 The clamping device 100 also includes a support member 71. A mounting member 60 is fixedly mounted on the support member 71, and a drive assembly 10 is fixedly mounted on the support member 71, with the drive assembly 10 and the mounting member 60 spaced apart. This facilitates the installation of the drive assembly 10 and improves the ease of assembly and mating between the drive assembly 10 and the first transmission member 20. In other embodiments, the drive assembly 10 may be directly connected to the first transmission member 20 and directly drive the first transmission member 20 to move. No limitation is made here.

[0081] In some embodiments, the clamping device 100 further includes a support column 72. The support column 72 is disposed on the support member 71. The support column 72 is connected to the first mounting portion 61. This provides stable support for the mounting member 60, ensuring the movement stability of the first transmission member 20, the plurality of second transmission members 30, and the plurality of clamping members 40.

[0082] In some embodiments, see Figure 2The drive assembly 10 is driven by one of the second transmission components 30, which in turn drives the first transmission component 20 to move, thereby driving the other second transmission components 30 to move. This facilitates the assembly of the drive assembly 10 and the second transmission components and allows for a spaced arrangement between the drive assembly 10 and the mounting component 60, thus avoiding interference between the operation of the drive assembly 10 and the lithium-ion battery.

[0083] In other embodiments, the drive component 10 may also directly drive the first transmission component 20.

[0084] In some embodiments, see Figure 3 The first transmission member 20 includes a first transmission gear 20a. The first transmission gear 20a is rotatably disposed on the first mounting portion 61. The second transmission member 30 includes a second transmission gear 31. Each second transmission gear 31 is rotatably connected to a corresponding second mounting portion 62. A plurality of second transmission gears 31 are disposed around the outside of the first transmission gear 20a, and all of the plurality of second transmission gears 31 mesh with the first transmission gear 20a. Thus, rotation of the first transmission gear 20a drives the plurality of second transmission gears 31 to rotate, and during the rotation of the second transmission gears 31, the two clamping portions 41 move relative to each other. Specifically, when the second transmission gear 31 rotates clockwise, the two clamping portions 41 move closer to each other, and when the second transmission gear 31 rotates counterclockwise, the two clamping portions 41 move away from each other; or, when the second transmission gear 31 rotates clockwise, the two clamping portions 41 move away from each other, and when the second transmission gear 31 rotates counterclockwise, the two clamping portions 41 move closer to each other. The gear meshing transmission method has the advantage of stable transmission. At the same time, gear meshing also has a self-locking effect to prevent the clamping part 40 from releasing the target part during the detection process, thereby further improving the clamping stability of the target part.

[0085] In some implementations, see Figure 3 The second transmission component 30 also includes a first connecting shaft 32. One end of the first connecting shaft 32 is rotatably connected to the third mounting portion 63. The second transmission gear 31 is fixedly connected to the other end of the first connecting shaft 32.

[0086] In some implementations, see Figure 2 The drive assembly 10 includes a motor, a second connecting shaft 12, and a drive gear 13. The motor is fixedly mounted on the support member 71. One end of the second connecting shaft 12 is connected to the motor. The other end of the second connecting shaft 12 is connected to the drive gear 13. The drive gear 13 is in transmission engagement with the first transmission gear 20a.

[0087] In some embodiments, the drive gear 13 is driven by one of the second drive gears 31. In other embodiments, the drive gear 13 directly meshes with the first drive gear 20a.

[0088] In other embodiments, the first transmission member 20 and the second transmission member 30 may also be configured as transmission wheel assemblies. The transmission wheel assembly may be a combination of a timing belt and a timing pulley, or a combination of a transmission chain and a transmission sprocket.

[0089] In some implementations, see Figure 3 The first transmission gear 20a can be constructed as an external gear ring. The external gear ring is rotatably fitted onto the second mounting portion 62. A plurality of second transmission gears 31 are arranged around the outside of the external gear ring.

[0090] In other embodiments, the first transmission gear 20a may also be configured as an internal gear ring. A plurality of second transmission gears 31 are arranged around the inner side of the internal gear ring. The drive gear 13 of the drive assembly 10 is disposed inside the plurality of second transmission gears 31 and meshes with the plurality of second transmission gears 31 simultaneously.

[0091] In some embodiments, see Figure 3 The clamping device 100 also includes a plurality of third transmission members 50. Each third transmission member 50 is connected to a corresponding second transmission member 30. The two clamping parts 41 are driven by the third transmission members 50 at intervals, and the third transmission members 50 are used to drive the two clamping parts 41 to move closer or further apart.

[0092] In some embodiments, the third transmission member 50 is located between the corresponding second transmission member 30 and the second mounting portion 62 to improve the structural compactness of the gripping device.

[0093] In some embodiments, see Figure 3 The third transmission member 50 includes a first transmission part 51 and a second transmission part 52. One end of the first transmission part 51 is connected to the second transmission member 30, and the other end of the first transmission part 51 is connected to one end of the second transmission part 52. The other end of the second transmission part 52 is connected to two clamping parts 41. Thus, by the second transmission member 30 driving the first transmission part 51 to move, and the first transmission part 51 driving the second transmission part 52 to move, the second transmission part 52 can drive the two clamping parts 41 to move closer or further apart.

[0094] In some embodiments, see Figure 3 and Figure 4 The third transmission component 50 also includes a lead screw 53. The lead screw 53 is connected to the second transmission part 52, and the lead screw 53 is provided with a first threaded section 531 and a second threaded section 532. The rotation direction of the first threaded section 531 is opposite to the rotation direction of the second threaded section 532. One clamping part 41 is threadedly engaged with the first threaded section 531, and the other clamping part 41 is threadedly engaged with the second threaded section 532.

[0095] Thus, during the rotation of the lead screw 53, the two clamping parts 41 can move closer or further apart, thereby achieving the clamping or release of the target part. The threaded engagement between the first threaded section 531 and the second threaded section 532 and the two clamping parts 41 has a self-locking characteristic, which can reduce the possibility of the two clamping parts 41 releasing the target part during the clamping process, thereby improving the clamping stability of the clamping member 40 on the target part.

[0096] One of the first threaded section 531 and the second threaded section 532 is provided with a left-hand thread. The other of the first threaded section 531 and the second threaded section 532 is provided with a right-hand thread.

[0097] Optionally, the clamping section 411 of one clamping part 41 is connected to the first threaded section 531, and the clamping section 411 of the other clamping part 41 is threadedly connected to the second threaded section 532.

[0098] In some embodiments, the second transmission part 52 is connected to the middle of the lead screw 53, and the first threaded section 531 and the second threaded section 532 are respectively provided on both sides of the second transmission part 52. In this way, the structural compactness of the third transmission member 50 can be improved. In other embodiments, the first threaded section 531 and the second threaded section 532 may be provided on the same side of the second transmission part 52.

[0099] In some implementations, see Figure 3 and Figure 4 The first transmission unit 51 includes a first bevel gear 511 and a third connecting shaft 512. The second transmission unit 52 includes a second bevel gear 52a. The first bevel gear 511 is connected to the second transmission member 30 via the third connecting shaft 512. The second bevel gear 52a meshes with the first bevel gear 511. A lead screw 53 connects to the second bevel gear 52a. The axial direction of the first bevel gear 511 is perpendicular to the axis of the second bevel gear 52a. This allows the rotation direction of the second transmission member 30 to be easily changed to the rotation direction of the lead screw 53.

[0100] In some embodiments, see Figure 3 The mounting component 60 also includes multiple limiting portions 64. Each second mounting portion 62 is correspondingly connected to two spaced-apart limiting portions 64. The two ends of the lead screw 53 are rotatably connected to the two limiting portions 64 respectively. The two clamping portions 41 of the clamping component 40 are located between the corresponding two limiting portions 64. The limiting portions 64 facilitate the installation of the lead screw 53 and limit the two clamping portions 41 to prevent them from disengaging from the lead screw 53.

[0101] In some embodiments, the limiting part 64 is connected to the side of the second mounting part 62 facing the third mounting part 63. In this way, the limiting part 64 can be prevented from interfering with the movement of the clamping part 41.

[0102] In other embodiments, the third transmission member 50 may include two transmission wheels and a transmission belt. Both transmission wheels are rotatably connected to the second mounting portion 62. One transmission wheel is connected to the second transmission member 30 and can rotate under the drive of the second transmission member 30. The transmission belt is wound around the two transmission wheels. The transmission belt includes two opposing belt segments. A clamping portion 41 is connected to one belt segment. The other clamping portion 41 is connected to the other belt segment. Thus, during the operation of the transmission belt, the two belt segments move in opposite directions, allowing the two clamping portions 41 to move closer or further apart. The transmission wheels may be configured as synchronous pulleys or sprockets. The transmission belt may be configured as a synchronous belt or a transmission chain.

[0103] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
