Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery clamping, in particular to a flippable device. Background Art

[0002] The clamping of the battery cell is closely related to the production efficiency and performance of the equipment. In the production process of lithium batteries, the clamping of the battery cell is an indispensable link. In the existing battery cell production process, especially in the flipping process of the battery cell clamp, in order to improve the working efficiency, multiple battery cell claws are integrated together and connected to the flipping mechanism, and the flipping mechanism drives multiple battery cell claws to flip simultaneously.

[0003] The inventor has found that the existing flipping mechanism for simultaneously flipping multiple cells has at least the following disadvantages:

[0004] In the prior art solution, one side of the plurality of battery claws is suspended on a flat plate, and the flipping mechanism drives the flat plate to rotate, thereby driving the plurality of battery claws to flip together. Since the axis of the synchronous flipping of the flat plate and the plurality of battery claws is located on the flat plate, and the center of gravity of the whole formed by the flat plate and the plurality of battery claws is biased toward the location of the battery claws, the distance between the axis and the center of gravity is large, resulting in a large moment of inertia, which seriously affects the flipping stability.

[0005] In addition, since the axis is located at one end of the battery claw, during the flipping process, the battery claw will be flipped with at least the entire length of the battery claw as the rotation radius, resulting in a large space occupancy rate during the flipping process, which undoubtedly increases the space occupancy cost. Utility Model Content

[0006] The utility model aims to provide a flip device, which can reduce the space occupancy rate during the flipping process and reduce the rotational inertia, thereby effectively improving the stability of the rotation.

[0007] The embodiment of the utility model is achieved as follows:

[0008] In a first aspect, the utility model provides a reversible device, comprising:

[0009] A flip plate, the flip plate comprising a first plate body and a second plate body connected and having an angle, the first plate body being used to be connected to a driving mechanism, the flip plate being used to rotate around a preset axis under the drive of the driving mechanism, the preset axis passing through the first plate body and having a spacing from a plate surface of the second plate body;

[0010] and a plurality of clamping mechanisms, wherein the plurality of clamping mechanisms are all connected to the second plate body, and each of the clamping mechanisms is used to grasp the battery core.

[0011] In an optional embodiment, the flip plate further includes a third plate body connected to the second plate body, and the third plate body is arranged parallel to and spaced from the first plate body.

[0012] Based on the above solution, the driving mechanism can be connected to the first plate and the third plate at the same time, thereby preventing the side of the second plate away from the first plate from being suspended in the air, and the flip plate flips more smoothly under the drive of the driving mechanism.

[0013] In an optional embodiment, the flippable device further includes a mounting frame, and the first plate body and the third plate body are both rotatably connected to the mounting frame with the preset axis as the axis center.

[0014] Based on the above solution, the rotation axes of the first plate body and the third plate body coincide, that is, both rotate around the preset axis, and both sides of the flip plate are supported by the mounting frame, so the flip plate is not easy to shake during the rotation process. At the same time, the mounting frame can effectively locate the position of the flip plate, thereby effectively ensuring the coaxiality of the rotation axis of the driving mechanism and the preset axis, improving the assembly quality, and running more smoothly.

[0015] In an optional embodiment, the mounting frame includes a first side panel, a connecting plate, and a second side panel connected in sequence, the flip plate is arranged between the first side panel and the second side panel, the first plate body is rotatably connected to the first side panel, and the third plate body is rotatably connected to the second side panel.

[0016] Based on the above solution, the mounting frame has a simple structure, is easy to manufacture, and has low cost. At the same time, the connection method between the flip plate and the mounting frame is simple, and is easy to disassemble and assemble.

[0017] In an optional embodiment, the flippable device further includes a limiting mechanism, and the limiting mechanism is used to limit the rotation range of the flip plate relative to the mounting frame.

[0018] Based on the above scheme, the rotation range of the flip plate is limited by the limiting mechanism during rotation, which is beneficial to adjusting the shape of the battery cell grasped by the clamping mechanism through the flip plate. Under the limiting action of the limiting mechanism, the position of the flip plate after rotation is more precise, making the shape adjustment of the battery cell more accurate, which is beneficial to the subsequent processing of the battery cell.

[0019] In an optional embodiment, the limiting mechanism includes a first limiting block and a second limiting block, the first limiting block is mounted on the first plate body or the third plate body, the second limiting block is correspondingly mounted on the first side plate or the second side plate, when the first limiting block rotates relative to the second limiting block, the first limiting block has a first position and a second position abutting against the second limiting block, and the first limiting block can rotate back and forth between the first position and the second position.

[0020] Based on the above scheme, the limit mechanism has a simple structure, is easy to manufacture and assemble. When set at the initial position, the first limit block abuts against the second limit block at the first position. When the flip plate is driven by the driving mechanism to rotate relative to the mounting frame, the first limit block rotates with the flip plate, and the second limit block remains stationary. In this way, the first limit block rotates relative to the second limit block, and after the flip plate rotates to the set position, the first limit block is just in the second position abutting against the second limit block. The first limit block and the second limit block cooperate to accurately limit the two extreme positions of the flip plate, and the limiting method is simple and reliable.

[0021] In an optional embodiment, the flippable device also includes a buffer mechanism, which is arranged between the clamping mechanism and the second plate body; the clamping mechanism and the second plate body are slidably matched to enable the clamping mechanism to approach or move away from the second plate body, and the buffer mechanism is used to provide resistance when the clamping mechanism approaches the second plate body.

[0022] Based on the above scheme, in the process of using the clamping mechanism to grasp the battery cell, the clamping mechanism has a tendency to approach the second plate body. During this process, the position of the second plate body remains unchanged, and the clamping mechanism transfers the external force to the buffer mechanism, thereby using the buffer mechanism to offset part of the impact force. The buffer mechanism has the function of energy unloading and buffering, avoiding rigid collision between the clamping mechanism and the second plate body, thereby improving the smoothness and reliability of operation.

[0023] In an optional embodiment, the buffer mechanism includes a positioning shaft and a buffer spring, the positioning shaft is installed on the clamping mechanism or the second plate body, the buffer spring is sleeved outside the positioning shaft, and the buffer spring abuts against the clamping mechanism and the second plate body at the same time.

[0024] Based on the above solution, the buffer mechanism has a simple structure and is easy to manufacture and assemble.

[0025] In an optional embodiment, the flippable device further includes a guide mechanism, which includes a linear bearing and a sliding shaft, wherein the linear bearing is mounted on the second plate body, and the sliding shaft is mounted on the clamping mechanism and slidably cooperates with the linear bearing.

[0026] Based on the above solution, when the clamping mechanism slides relative to the flip plate, the guidance is achieved by relying on the cooperation of the linear bearing and the sliding shaft. The friction between the clamping mechanism and the flip plate is small, and the sliding of the clamping mechanism is stable.

[0027] In an optional embodiment, the clamping mechanism includes an integrated board and a plurality of clamps, wherein the plurality of clamps are mounted on the integrated board, the integrated board is connected to the second board body, and each of the clamps is used to grasp a battery cell.

[0028] Based on the above solution, multiple clamps are installed on the integrated board, and the integrated board is used to fix the multiple clamps on the second plate body, thereby reducing the difficulty of assembly and improving the assembly efficiency.

[0029] The beneficial effects of the embodiments of the utility model are:

[0030] In summary, the flip device provided in this embodiment has a first plate body of the flip plate connected to the driving mechanism, and the preset axis of the flip plate passes through the first plate body and has a spacing with the plate surface of the second plate body, that is, the position of the preset axis is translated toward the side where the first plate body is located compared to the rotation axis of the flat flip structure of the prior art, and the center of gravity of the entire flip device is closer to the preset axis, and the distance between the center of gravity of the flip device and the preset axis is smaller, and the center of gravity can even be designed to be located on the preset axis, with a small moment of inertia, and the flip device is more stable and reliable during the rotation process. At the same time, because the distance between the center of gravity and the preset axis is small and can even be zero, the rotation radius of the flip device is smaller than the length of the clamping mechanism, and the rotation area of ​​the flip device is small, which can reduce the space occupancy rate during the flipping process and reduce the space occupancy cost.

DETAILED DESCRIPTION

[0042] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0043] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0045] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0046] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0047] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] Please combine Figure 7 , where a represents the flip axis, b represents the center of gravity of the existing flip mechanism, c represents the trajectory of the flip of the center of gravity, and d represents the trajectory of the flip of the end of the battery claw away from the flip axis. L is the distance from the flip axis to the end of the battery claw away from the flip axis, and L≥the length of the battery claw. In the prior art, a flip mechanism for synchronous flipping of multiple batteries includes a flat plate 01 and multiple battery claws 02 arranged side by side. The multiple battery claws 02 are all installed on a plate surface of the flat plate 01. During operation, a rotating mechanism is used to connect to one side of the flat plate 01, and the flat plate 01 is driven to rotate by the rotating mechanism to drive the multiple battery claws 02 to rotate together. Since the flip axis a is located inside the flat plate 01, the center of gravity b of the flip mechanism falls on the battery claw 02. The distance between the flip axis a and the center of gravity b is large, resulting in a large rotation area and a large moment of inertia of the flip mechanism. Therefore, the stability of the flip mechanism in the prior art is poor.

[0049] In view of this, the designer provides a flip device that improves the flipping stability by reducing the moment of inertia.

[0050] Please combine Figure 1 and Figure 2 In this embodiment, the flip device includes a flip plate 100 and a plurality of clamping mechanisms 200. The flip plate 100 includes a first plate body 110 and a second plate body 120 that are connected and have an angle. Preferably, the angle here is generally 90°. The first plate body 110 is connected to one end of the second plate body 120. At this time, the first plate body 110 and the second plate body 120 form an L-shaped structure. The first plate body 110 is used to be connected to the driving mechanism 700, and the flip plate 100 is used to rotate around a preset axis driven by the driving mechanism 700. The preset axis passes through the first plate body 110 and has a spacing with the plate surface of the second plate body 120. Multiple clamping mechanisms 200 are connected to the second plate body 120, and each clamping mechanism 200 is used to grab the battery cell 001.

[0051] It should be understood that the flip device is mainly suitable for grabbing and flipping the battery cell 001. Obviously, according to the needs, the flip device can also be used to grab and flip other workpieces. The specific type of the object to be grabbed is not limited in this embodiment. In addition, the preset axis described here can also be understood as a flip axis.

[0052] Based on the above, the working principle of the reversible device provided in this embodiment is as follows:

[0053] Please combine Figure 8 , where a represents the flip axis, b represents the center of gravity of the flip device, and e represents the trajectory of the center of gravity flipping. When the center of gravity coincides with the flip axis, the trajectory of the center of gravity coincides with the trajectory of the flip axis. f represents the trajectory of the end of the clamping mechanism 200 away from the flip axis flipping. L1 is the distance from the flip axis to the end of the clamping mechanism 200 away from the flip axis, and L1 is less than the length of the clamping mechanism 200. The first plate body 110 is connected to the driving mechanism 700, and the flip plate 100 is first adjusted to be in the initial position. Then, after using multiple clamping mechanisms 200 to clamp multiple battery cells 001 respectively, the driving mechanism 700 is started, and the driving mechanism 700 is used to drive the flip plate 100 to move so as to drive the multiple battery cells 001 to rotate at the same time. When the battery cell 001 rotates to the set angle, the driving mechanism 700 stops to achieve synchronous flipping of multiple battery cells 001. When the battery cell 001 is prepared, the clamping mechanism 200 releases the battery cell 001 and returns to the initial position driven by the driving mechanism 700, and the cycle is completed.

[0054] Since the driving mechanism 700 is connected to the first plate body 110 of the flip plate 100, the axis of the driving mechanism 700 coincides with the preset axis and passes through the first plate body 110, and has a spacing with the plate surface of the second plate body 120, that is, the position of the preset axis is translated toward the side where the first plate body 110 is located compared with the rotation axis of the flat flip structure of the prior art, the distance between the end of the clamping mechanism 200 and the preset axis is reduced, the center of gravity of the entire flip device is closer to the preset axis, the distance between the center of gravity of the flip device and the preset axis is smaller, the moment of inertia is small, and the flip device is more stable and reliable during the rotation process. It can also reduce the rotation radius of the flip device, reduce the space occupancy rate, and reduce the space occupancy cost.

[0055] It should be understood that the center of gravity of the flippable device can be designed to coincide with the preset axis as required, so as to minimize the shaking generated during the rotation process.

[0056] The following embodiments illustrate the detailed structure of the flippable device provided in the present application by way of examples.

[0057] Please combine Figure 1 In this embodiment, optionally, the reversible device includes a reversible plate 100, a plurality of clamping mechanisms 200, a mounting frame 300, a limiting mechanism 400, a buffer mechanism 500, a guide mechanism 600 and a driving mechanism 700. The clamping mechanism 200 and the reversible plate 100 are slidably connected in a direction perpendicular to a preset axis through a corresponding guide mechanism 600, and the buffer mechanism 500 is arranged between the reversible plate 100 and the clamping mechanism 200, and can provide a buffering effect when the clamping mechanism 200 slides close to the reversible plate 100. The reversible plate 100 and the mounting frame 300 are rotatably matched around a preset axis, and the mounting frame 300 is connected to the driving mechanism 700. In addition, the mounting frame 300 can also be used to connect the reversible device as a whole to other mechanisms. The limiting mechanism 400 is installed on the reversible plate 100 or the mounting frame 300, and is used to limit the rotation range of the reversible plate 100 relative to the mounting frame 300. During operation, the driving mechanism 700 and the mounting frame 300 serve as the base and remain in the same position. The driving mechanism 700 can drive the multiple clamping mechanisms 200 to rotate through the flip plate 100, thereby driving the multiple battery cells 001 grasped by the clamping mechanisms 200 to flip simultaneously. During the rotation of the flip plate 100, the initial position of the flip plate 100 and the target position after flipping are limited by the limit mechanism 400, so as to accurately control the movement range of the flip plate 100, and then accurately control the shape of the battery cells 001.

[0058] Please combine Figure 3Optionally, the flip plate 100 includes a first short axis 140, a first plate body 110, a second plate body 120, a third plate body 130 and a second short axis 150 connected in sequence. The first plate body 110, the second plate body 120 and the third plate body 130 are all rectangular plates, and the first plate body 110 and the third plate body 130 are located on opposite sides of the second plate body 120 and are arranged in parallel and spaced apart, and the first plate body 110 and the third plate body 130 are both perpendicular to the second plate body 120. In this way, the flip plate 100 is generally in a U-shaped structure, and the area surrounded by the flip plate 100 can provide a certain space for installing the clamping mechanism 200. Since the clamping mechanism 200 is at least partially located in the area surrounded by the flip plate 100 at this time, the center of gravity of the clamping mechanism 200 can be closer to the preset axis, so that the stability is high when the flip plate 100 and the clamping mechanism 200 rotate at the same time, and the space occupancy rate can be reduced during the flipping process, thereby reducing the space occupancy cost.

[0059] The first short shaft 140 is fixed on the first plate body 110, and the first short shaft 140 protrudes from the first plate body 110 in a direction away from the third plate body 130. The second short shaft 150 is fixed on the third plate body 130, and the second short shaft 150 protrudes from the third plate body 130 in a direction away from the first plate body 110. The first short shaft 140 and the second short shaft 150 are coaxially arranged, and the axes of the two coincide with the preset axis, and the preset axis has a spacing with the inner plate surface of the second plate body 120. A plurality of assembly holes 121 are provided on the second plate body 120. For example, in this embodiment, the number of the assembly holes 121 is four and they are evenly spaced in the extending direction of the preset axis, and each assembly hole 121 is a circular hole.

[0060] It should be understood that the flip plate 100 can be set as an integrally formed structure, which has a simple structure, is easy to process and manufacture, is conducive to mass production, and reduces manufacturing costs. In addition, the overall structure has no seams, high strength, is not easy to deform, and has a long service life.

[0061] For example, the flip plate 100 can be made into an integrated structure by injection molding, or by casting, etc.

[0062] In addition, the positions of the first short axis 140 and the second short axis 150 can be as close as possible to the sides of the first plate body 110 and the third plate body 130 away from the second plate body 120, so that the center of gravity of the overall structure falls as close to the preset axis as possible, further improving the rotation stability.

[0063] Please combine Figure 4Optionally, the mounting frame 300 includes a first side plate 310, a connecting plate 320, a second side plate 330, a first reinforcing plate 340, a second reinforcing plate 350, a first bearing 360, a second bearing 370, a first pressing plate 380, and a second pressing plate 390. The first side plate 310 and the second side plate 330 are arranged in parallel and spaced apart and are both vertically connected to the same plate surface of the connecting plate 320. The first reinforcing plate 340 and the second reinforcing plate 350 are both triangular plates, the first reinforcing plate 340 is connected to the first side plate 310 and the connecting plate 320 at the same time, and the second reinforcing plate 350 is connected to the second side plate 330 and the connecting plate 320 at the same time. The first reinforcing plate 340 and the second reinforcing plate 350 can improve the stability and reliability of the overall structure of the mounting frame 300.

[0064] A first counterbore 311 is provided on the plate surface of the first side plate 310 facing the second side plate 330, a first bearing 360 is installed in the first counterbore 311, a first pressing plate 380 is connected to the first side plate 310 and restricts the first bearing 360 in the first counterbore 311. A second counterbore 331 is provided on the plate surface of the second side plate 330 facing the first side plate 310, a second bearing 370 is installed in the second counterbore 331, a second pressing plate 390 is connected to the second side plate 330 and restricts the second bearing 370 in the second counterbore 331. After the first bearing 360 and the second bearing 370 are assembled, their axes are collinear. The assembly method of the first bearing 360 and the second bearing 370 is simple, and both are located in the countersunk holes. The countersunk holes are used for limiting, and the installation position is accurate and reliable, ensuring the coaxiality of the first bearing 360 and the second bearing 370. The portion protruding axially from the first side plate 310 and the second side plate 330 is small, reducing the axial installation space required for the overall structure and improving the axial compactness of the overall structure.

[0065] It should be understood that the first side plate 310, the second side plate 330, the first reinforcing plate 340 and the second reinforcing plate 350 can be fixedly connected to the connecting plate 320 by fasteners such as screws. In addition, the first reinforcing plate 340 can be fixedly connected to the first side plate 310 by fasteners such as screws, and the second reinforcing plate 350 can be fixedly connected to the second side plate 330 by fasteners such as screws.

[0066] It should be noted that the first reinforcing plate 340 and the second reinforcing plate 350 may be disposed between the first side plate 310 and the second side plate 330 to improve the compactness of the overall structure.

[0067] Please combine Figure 1It should be noted that the flip plate 100 is mounted on the mounting frame 300. Specifically, the flip plate 100 is located between the first side plate 310 and the second side plate 330 of the mounting frame 300. The first short shaft 140 passes through the first pressure plate 380 and is arranged in the first bearing 360. The second short shaft 150 passes through the second pressure plate 390 and is arranged in the second bearing 370. The first bearing 360 and the second bearing 370 cooperate to carry the flip plate 100. When the flip plate 100 is driven by the driving mechanism 700 to rotate around the preset axis relative to the mounting frame 300, the friction force is small, the wear is small, and the rotation is stable and reliable. In addition, the accuracy of the installation position of the flip plate 100 is improved by the first bearing 360 and the second bearing 370, which can effectively ensure the coaxiality of the first short shaft 140, the second short shaft 150 and the output shaft of the driving mechanism 700, improve the assembly quality, and improve the running stability.

[0068] It is worth noting that the first short shaft 140 extends out of the first bearing 360 to facilitate the assembly of the first short shaft 140 with the output shaft of the driving mechanism 700. At the same time, the second short shaft 150 extends out of the second bearing 370 to facilitate the cooperation between the second short shaft 150 and the limiting mechanism 400.

[0069] Please combine Figure 4 and Figure 5In this embodiment, optionally, the limiting mechanism 400 includes a first limiting block 410 and a second limiting block 420. The first limiting block 410 can be installed on the second short shaft 150 by fasteners such as screws, and the first limiting block 410 is located on the side of the second side plate 330 away from the first side plate 310. The first limiting block 410 can rotate with the flip plate 100. At the same time, the outer peripheral surface of the first limiting block 410 is provided with a limiting groove 411 arranged around a preset axis, and the limiting groove 411 has a first groove wall 4111 and a second groove wall 4112 in the circumferential direction of the preset axis, for example, the first groove wall 4111 and the second groove wall 4112 are arranged vertically, and the flipping range is limited to 0 to 90°. The second limiting block 420 can be fixed on the second side plate 330 by fasteners such as screws, and the second limiting block 420 is convexly arranged on the side of the second side plate 330 away from the first side plate 310. During the rotation of the first limit block 410 relative to the second limit block 420, the first limit block 410 can abut against the first groove wall 4111, thereby limiting the first limit block 410 from continuing to rotate through the first groove wall 4111; at this time, the first limit block 410 can be reversed, and after the first limit block 410 is reversed, it can abut against the second groove wall 4112, thereby limiting the first limit block 410 from continuing to rotate through the second groove wall 4112. It is assumed that the position where the first limit block 410 abuts against the first groove wall 4111 is the first position of the first limit block 410, at which time the flip plate 100 is in the initial position; the position where the first limit block 410 abuts against the second groove wall 4112 is the second position of the first limit block 410, at which time the flip plate 100 is in the target position.

[0070] It should be understood that in other embodiments, the first limit block 410 and the second limit block 420 can cooperate to limit the rotation of the flip plate 100 within any other angle range, not limited to rotation within the 90° range, and can be adjusted as needed. The scope of application is wide and is not exhaustively listed in this embodiment.

[0071] In addition, the first limiting block 410 may also be disposed on the first plate body 110 , and correspondingly, the second limiting block 420 is disposed on the first side plate 310 .

[0072] In this embodiment, optionally, the number of the clamping mechanisms 200 may be two, and the structure of each clamping mechanism 200 may be set to be the same. In order to avoid repeated description, the structure of one clamping mechanism 200 is used as an example to illustrate in this embodiment.

[0073] Please combine Figure 3 and Figure 6For example, the clamping mechanism 200 includes an integrated board 210 and two clamping jaws 220, and the two clamping jaws 220 are both mounted on the integrated board 210 and arranged at intervals. The integrated board 210 can be a rectangular board, and a first fixing hole 211 and two second fixing holes 212 can be set on the integrated board 210. The first fixing hole 211 can be set between the two second fixing holes 212. The first fixing hole 211 can be a round hole, and the two second fixing holes 212 can be set as threaded holes. Each clamping jaw 220 can include two clamping arms 221, and at least one of the two clamping arms 221 can be controlled by a driving member 222 such as a cylinder or a hydraulic cylinder, so as to adjust the distance between the two clamping arms 221, and then the battery cell 001 can be clamped or released by the cooperation of the two clamping arms 221. Furthermore, a sensing sheet 223 can be provided in the clamping space formed between the two clamping arms 221. The sensing sheet 223 can be used to determine whether the battery cell 001 is clamped in the clamping space, and whether the position of the battery cell 001 is at the set position of the clamping space, thereby improving the stability and reliability of the clamping claw 220 in clamping the battery cell 001.

[0074] It should be understood that the driving member 222 can be fixed to the integrated board 210 by fasteners such as screws.

[0075] It should be noted that each clamping mechanism 200 is guided and matched with the second plate body 120 of the flip plate 100 through two guide mechanisms 600. Thus, when the number of clamping mechanisms 200 is two, the number of guide mechanisms 600 is four. The structures of the four guide mechanisms 600 are arranged in the same manner. In order to avoid repeated description, the present embodiment is described by taking the cooperation of one guide mechanism 600 with the flip plate 100 and the clamping mechanism 200 as an example.

[0076] Please combine Figure 3Optionally, the guide mechanism 600 includes a linear bearing 610 and a sliding shaft 620, wherein the sliding shaft 620 has a first end and a second end opposite to each other, and an anti-dropping end cap 621 is provided on the first end. The sliding shaft 620 is inserted into the linear bearing 610 by its second end, and the sliding shaft 620 and the linear bearing 610 are slidably matched. During assembly, the linear bearing 610 is inserted into the corresponding assembly hole 121, and the linear bearing 610 can be fixedly connected to the second plate body 120 by fasteners such as screws. At the same time, after the sliding shaft 620 passes through the linear bearing 610, it is fixedly connected to the corresponding second fixing hole 212 on the integrated board 210 by its second end. For example, the shaft section of the sliding shaft 620 near the second end can be set as a threaded rod section, and the threaded rod section on the sliding shaft 620 is screwed and fixed with the second fixing hole 212, and the anti-slip end cap 621 on the sliding shaft 620 cooperates with the integrated board 210 to prevent the sliding shaft 620 from slipping out of the linear bearing 610, and also prevent the clamping mechanism 200 from leaving the flip plate 100. When the clamping mechanism 200 slides relative to the flip plate 100, the integrated board 210 drives the sliding shaft 620 to slide relative to the linear bearing 610, with good guiding effect, small friction, and stable and reliable sliding.

[0077] Please combine Figure 3 In this embodiment, it should be noted that each clamping mechanism 200 can cooperate with the flip plate 100 through a buffer mechanism 500, so that the two clamping mechanisms 200 cooperate with the flip plate 100 through two buffer mechanisms 500 respectively. In this embodiment, the structures of the two buffer mechanisms 500 are set to be the same. In order to avoid repeated description, the cooperation of one buffer mechanism 500 with the flip plate 100 and the clamping mechanism 200 is taken as an example for description.

[0078] Please combine Figure 3Optionally, the buffer mechanism 500 includes a positioning shaft 510 and a buffer spring 520. The buffer spring 520 is sleeved outside the positioning shaft 510. The positioning shaft 510 can guide the buffer spring 520 to compress or extend, so that the deformation of the buffer spring 520 is stable, and the elastic force provided is stable and reliable. During assembly, the buffer spring 520 is first sleeved outside the positioning shaft 510, and then the positioning shaft 510 is set between the integrated board 210 and the second board body 120, and one end of the positioning shaft 510 can be fixed in the first fixing hole 211 on the integrated board 210. For example, the positioning shaft 510 can be screwed and fixed to the first fixing hole 211, which is convenient to operate. When the positioning shaft 510 is installed, the buffer spring 520 is in a compressed state and is clamped between the integrated board 210 and the second board 120. The two ends of the buffer spring 520 are respectively in contact with the integrated board 210 and the second board 120, so that the buffer spring 520 has an elastic force to move outward and restore the deformation. In this way, the clamping mechanism 200 has a sliding tendency away from the second board 120, so that the anti-slip end cap 621 is pressed against the linear bearing 610, which plays a role in stabilizing the clamping mechanism 200. After the clamping mechanism 200 grabs the battery cell 001, the clamping mechanism 200 moves close to the second board 120 under the action of the battery cell 001, and the buffer spring 520 is further compressed, providing resistance to prevent the clamping mechanism 200 from approaching the second board 120, avoiding the rigid collision between the integrated board 210 of the clamping mechanism 200 and the second board 120, thereby improving reliability.

[0079] Please combine Figure 4 In this embodiment, optionally, the driving mechanism 700 includes a motor 710 and a reducer 720, the output shaft of the motor 710 is connected to the input shaft of the reducer 720, and the output shaft of the reducer 720 is connected to the first short shaft 140. After the motor 710 is started, the speed is adjusted by the reducer 720 to transfer the torque to the first short shaft 140, thereby driving the flip plate 100 to rotate.

[0080] The reversible device provided in this embodiment reduces the moment of inertia generated during the rotation of the reversible device by shortening the distance between the center of gravity of the reversible device and the preset axis, thereby improving the stability of the reversible device during the rotation.

For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
