[0018] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0021] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0022] This technical solution proposes a laser cleaning device, comprising: Rack 100; The lifting mechanism 200 is provided on the frame 100. The lifting mechanism 200 has a fixed end and a lifting end. The fixed end is fixedly connected to the frame 100, and the lifting end is used to place multiple battery cells 10 and drive the multiple battery cells 10 to rise and fall synchronously. A clamping and rotating mechanism 300 is provided on the frame 100. Two clamping and rotating mechanisms 300 are provided. The two clamping and rotating mechanisms 300 are respectively provided on both sides of the lifting mechanism 200. The two clamping and rotating mechanisms 300 cooperate with each other to clamp the multiple battery cells 10, and the two clamping and rotating mechanisms 300 drive the multiple battery cells 10 to rotate synchronously. The laser cleaning mechanism 400 is disposed on the frame 100 and above the clamping and rotating mechanism 300 . The laser cleaning mechanism 400 is used to clean and roughen the outer shell of the clamped battery cell 10 .

[0023] In the technical solution of the present invention, the laser cleaning equipment can synchronously clean and texturize multiple battery cells 10 through laser. During processing, the multiple battery cells 10 need to be placed on the lifting mechanism 200 first, and then the lifting mechanism 200 drives the multiple battery cells 10 to rise synchronously and reach the clamping and rotating mechanism 300 above. Then, the two clamping and rotating mechanisms 300 cooperate to clamp the multiple battery cells 10 and drive the multiple battery cells 10 to rotate synchronously. While rotating, the laser cleaning mechanism 400 above performs laser cleaning and texturizing on the cylindrical surfaces of the multiple battery cells 10. In this way, the multiple battery cells 10 can be cleaned and texturized synchronously, thereby improving the processing efficiency.

[0024] Specifically, if Figures 1 to 9 The laser cleaning equipment is mainly composed of a frame 100, a lifting mechanism 200, a clamping and rotating mechanism 300, and a laser cleaning mechanism 400; among them, the frame 100 serves as the supporting body of the entire device, and its appearance is a rectangular frame structure, with space formed inside to accommodate and install other mechanisms. Anchor bolts can be installed at the bottom to fix the entire device to the ground or other supporting platforms. The lifting mechanism 200 is installed on the frame 100 and is located at the bottom of the frame 100. The lifting mechanism 200 includes a guide rail, which extends vertically. A slider is slidably provided on the guide rail, and a workbench is provided on the slider. The workbench is used to place multiple battery cells 10. Multiple battery cells 10 can be arranged in a row in the same horizontal plane. In addition, a driving device can also be provided on the frame 100. The driving device includes a motor, a screw rod and a nut. The screw rod extends vertically and is rotatably connected to the frame 100. The nut is fixed on the workbench and cooperates with the screw rod thread. The motor drives the screw rod to rotate, thereby driving the workbench to rise and fall through the nut to lift the multiple battery cells 10 to a predetermined height.

[0025] There are two clamping and rotating mechanisms 300, which are symmetrically arranged on both sides of the lifting mechanism 200. The two clamping and rotating mechanisms 300 are fixedly mounted on the frame 100. Each clamping and rotating mechanism 300 mainly consists of a clamping arm and a cylinder that drives the clamping arms on the two clamping and rotating mechanisms 300 to move closer or farther away from each other. A driving rod is provided on the clamping arm, which can rotate relative to the clamping arm. There can be multiple driving rods, and the number of driving rods can be equivalent to the number of battery cells 10. When the lifting mechanism 200 lifts multiple battery cells 10 into place, the two clamping arms can extend relative to each other, so that the driving rods cooperate with each other to clamp and fix the multiple battery cells 10. In addition, a rotation drive device can be provided at the bottom of the clamping and rotating mechanism 300. The rotation drive device can be connected to the driving rod. When the rotation drive device is started, it can drive the driving rod and the battery cell 10 it clamps to rotate synchronously. The rotation of the driving rods on the two clamping and rotating mechanisms 300 is coordinated and controlled by the same control system to ensure that the multiple battery cells 10 remain synchronized during the rotation process.

[0026] The laser cleaning mechanism 400 is installed on the frame 100 and is located above the clamping and rotating mechanism 300. The laser cleaning mechanism 400 includes a slide rail extending along the arrangement direction of the multiple battery cells 10. A workbench is slidingly provided on the slide rail. The workbench is driven to slide by an electric cylinder. A laser emitter is provided on the workbench. The laser emitter generates a high-energy laser beam, which can clean the multiple battery cells 10 below and roughen the surface. At the same time, the clamping and rotating mechanism 300 drives the multiple battery cells 10 to rotate, thereby realizing the processing of a full circle of the battery cells 10.

[0027] In the above scheme, through the coordinated work of the above components, the laser cleaning equipment can simultaneously clean and roughen the outer shells of multiple battery cells 10, provide good surface conditions for the subsequent glue spraying process, improve the efficiency of battery cell 10 processing, and also ensure the consistency of the surface treatment quality of each battery cell 10.

[0028] like Figure 2 A structural form of the clamping and rotating mechanism 300 is shown. In this solution, the clamping and rotating mechanism 300 includes: The sliding member 310 is slidably mounted on the frame 100 , and the sliding members 310 on the two clamping and rotating mechanisms 300 slide relative to each other along a first direction; The first driving member 320 is provided on the frame 100 and is drivingly connected to the sliding member 310. The first driving member 320 drives the sliding member 310 to slide; A plurality of clamping terminals 330 are provided on the sliding member 310 . The plurality of clamping terminals 330 are arranged parallel to and spaced apart from each other along a second direction, the second direction being different from the first direction. Each clamping terminal 330 has a rotating end. The rotating ends on the two clamping rotating mechanisms 300 cooperate with each other to clamp the battery cell 10 . The driving assembly 340 is disposed on the sliding member 310 on one of the clamping and rotating mechanisms 300 and is in transmission connection with the plurality of rotating ends.

[0029] The sliding member 310 is mounted on the frame 100 and is capable of relative sliding along a first direction, which is the direction in which the two clamping and rotating mechanisms 300 are arranged on the frame 100. Specifically, the sliding member 310 may utilize a linear slide structure, with its bottom portion mating with the slide rail on the frame 100 to ensure smooth sliding of the sliding member 310 along the frame 100 along the first direction. A first driving member 320 is mounted on the frame 100 and is drivingly connected to the sliding member 310, for driving the sliding member 310 to slide along the first direction. In this embodiment, the first driving member 320 may utilize a telescopic cylinder structure. The first driving member 320 extends and retracts along the first direction, ensuring that the clamping and rotating mechanisms 300 can complete the clamping and release operations. The clamping terminal 330 is a component in the clamping and rotating mechanism 300 that directly contacts and clamps the battery cell 10. It is arranged on the sliding member 310. In this extended solution, there are multiple clamping terminals 330, and the multiple clamping terminals 330 are arranged in parallel and at intervals along the second direction (the direction in which the multiple battery cells 10 are arranged). Each clamping terminal 330 is provided with a rotating end at one end facing the battery cell 10. The rotating end can be a structure such as a rotating shaft 332. The rotating end can rotate in the first direction as an axis and can move along the first direction with the clamping terminal 330. The rotating ends on the two clamping and rotating mechanisms 300 cooperate with each other. When the sliding members 310 of the two clamping and rotating mechanisms 300 slide toward each other, the rotating ends on the two clamping and rotating mechanisms 300 gradually approach the battery cell 10, and the rotating ends clamp and fix the battery cell 10 from both sides. In addition, a driving assembly 340 is provided on the sliding member 310 of one of the clamping rotating mechanisms 300. The driving assembly 340 may include a power source such as a motor. The driving assembly 340 and the multiple rotating ends may be connected by belt drive or gear drive. When the driving assembly 340 is started, the multiple rotating ends are driven to rotate synchronously through the transmission of the synchronous belt or gear, thereby driving the clamped battery cells 10 to rotate synchronously. By being driven by the same power source, it can be ensured that the multiple battery cells 10 maintain a consistent speed and rotation direction during the rotation process, so that the surface of the battery cells 10 can be evenly subjected to laser cleaning and texturing treatment, thereby improving the uniformity and consistency of the treatment effect.

[0030] Figure 9 A structural form of the clamping terminal 330 is shown. In this solution, the clamping terminal 330 includes: Connecting member 331, fixedly connected to sliding member 310; The rotating shaft 332 is movably disposed on the connecting member 331 and extends along the first direction. The rotating shaft 332 slides relative to the connecting member 331 along the first direction and rotates around its own axis. The clamping member 333 is provided on one end of the rotating shaft 332 close to the battery cell 10 , and the clamping member 333 is used to abut against the battery cell 10 ; The elastic component 334 has one end connected to the connecting member 331 and the other end connected to the rotating shaft 332 .

[0031] Among them, the connecting member 331 is the basic component of the clamping terminal 330. The connecting member 331 can be a flange or other structure. The connecting member 331 is used to fix the clamping terminal 330 on the sliding member 310. In this embodiment, the connecting member 331 and the sliding member 310 are fixed by screws to facilitate assembly. A through hole extending along a first direction is provided on the connecting member 331, and the rotating shaft 332 is rotatably provided in the through hole and can slide in the through hole along the first direction. A clamping member 333 is provided on the rotating shaft 332 at one end close to the battery cell 10. The clamping member 333 is a component that directly contacts and clamps the battery cell 10. In this embodiment, the clamping member 333 can be made of a flexible material (such as rubber or elastic plastic), and its shape is designed to be a structure that matches the outer shape of the battery cell 10 to increase the contact area with the battery cell 10 and provide a more uniform clamping force. The clamping member 333 can be fixed to the rotating shaft 332 by screws or snaps to ensure stability and reliability during the clamping process. In addition, the surface of the clamping member 333 can be provided with anti-slip grooves to enhance the gripping ability of the battery cell 10 and prevent the battery cell 10 from sliding during rotation. Furthermore, an elastic component 334 is provided on the connector 331. This elastic component 334 can be a compression spring, with one end connected to the connector 331 and the other end connected to a slider. A rotating shaft 332 is rotatably connected to the slider. The elastic component 334 is capable of expanding and contracting along a first direction. During operation, when the slider 310 drives the clamping terminal 330 toward the battery cell 10, the clamping member 333 first contacts the surface of the battery cell 10. As the slider 310 continues to move, the rotating shaft 332, under the influence of the battery cell 10, slides relative to the connector 331 along the first direction, and the elastic component 334 begins to compress. The elastic force generated by the elastic component 334 is transmitted to the clamping member 333 through the rotating shaft 332, so that the clamping member 333 can be in close contact with the surface of the battery cell 10 to achieve preliminary clamping of the battery cell 10. At the same time, the elastic component 334 can also reduce the impact when it abuts against the battery cell 10. During the rotation of the battery cell 10, the clamping member 333 can maintain sufficient friction with the battery cell 10 by virtue of its flexible material and the elastic force provided by the elastic component 334, ensuring that the battery cell 10 can still maintain a stable position and posture during rotation, which not only improves the reliability and adaptability of the clamping of the battery cell 10, but also ensures the effect of laser cleaning and roughening.

[0032] like Figure 7 As shown, in one embodiment of the present invention, a sealing member 335 is provided on one end of the clamping member 333 facing the battery cell 10, and a first channel 20 is also provided on the clamping member 333. A second channel 30 is provided on the rotating shaft 332. The first channel 20 is connected to the second channel 30, and the second channel 30 is used to connect to the negative pressure generating device; when the clamping member 333 abuts the battery cell 10, the sealing member 335 is sealed with the end of the battery cell 10, and a negative pressure cavity connected to the first channel 20 is formed between the clamping member 333 and the battery cell 10.

[0033] Specifically, the seal 335 is arranged on the end of the clamping member 333 facing the battery cell 10, and can be made of wear-resistant rubber material. Its shape is designed to be an annular sealing ring that matches the shape of the end of the battery cell 10. The seal 335 is fixed to the clamping member 333 by bonding or clamping. A first channel 20 is provided inside the clamping member 333. The first channel 20 penetrates the clamping member 333 along the first direction and is connected to the area surrounded by the seal 335. A second channel 30 is provided inside the rotating shaft 332. The second channel 30 penetrates both ends of the rotating shaft 332 along the axial direction of the rotating shaft 332 and is connected to the first channel 20 on the clamping member 333. A connection interface is provided on the end of the rotating shaft 332 away from the clamping member 333 for connecting to the pipeline of the negative pressure generating device. A quick connector design can be adopted at the connection interface to facilitate installation and disassembly. The negative pressure generating device can be a vacuum pump or other structure. When the clamping member 333 abuts the end of the battery cell 10, the sealing member 335 fits tightly against the end of the battery cell 10, forming a sealing effect. At this time, the negative pressure generating device is activated, and the vacuum pump extracts the air between the clamping member 333 and the battery cell 10 through the second channel 30 and the first channel 20, forming a negative pressure chamber. The adsorption force generated by the negative pressure chamber further enhances the fixing effect of the clamping member 333 on the battery cell 10, ensuring that the battery cell 10 remains stable during the rotation and laser cleaning process without displacement or shaking. In the above structure, the clamping member 333 achieves stable clamping of the battery cell 10 through the cooperation of the sealing member 335 and the negative pressure channel, ensuring the effect of laser cleaning and texturing.

[0034] like Figure 7 A structural form of the clamping member 333 is shown. In this solution, the clamping member 333 includes: The connecting sleeve 3331 is sleeved on the rotating shaft 332, and the connecting sleeve 3331 and the rotating shaft 332 are detachably connected; The clamping sleeve 3332 is disposed on one end of the connecting sleeve 3331 facing the battery cell 10 . The clamping sleeve 3332 is used to abut against the battery cell 10 . The first channel 20 is formed on the clamping sleeve 3332 and the connecting sleeve 3331 .

[0035] Specifically, the connecting sleeve 3331 is in the shape of a cylindrical sleeve, which is detachably connected to the rotating shaft 332. For example, a groove is provided at one end of the connecting sleeve 3331, and the inner wall of the groove is provided with an internal thread. The internal thread cooperates with the corresponding external thread on the rotating shaft 332 to achieve a detachable connection. This connection method is not only convenient for installation and disassembly, but also can withstand greater torque and tension, ensuring stability and reliability between the connecting sleeve 3331 and the rotating shaft 332 during the clamping process; in addition, the connecting sleeve 3331 can also be detachably connected to the rotating shaft 332 by inserting a pin on the side; with a detachable structure, when in use, the corresponding clamping part 333 can be replaced according to the specifications and models of the battery cell 10, thereby improving compatibility. In addition, the clamping sleeve 3332 is installed on the connecting sleeve 3331 at one end facing the battery cell 10. The clamping sleeve 3332 can be fixed to the connecting sleeve 3331 by bonding or clamping. The clamping sleeve 3332 can be made of flexible rubber material and be disc-shaped. The end face of the clamping sleeve 3332 can be provided with a groove matching the shape of the battery cell 10 to cooperate with the battery cell 10 and improve the stability of clamping; in addition, the first channel 20 is formed on the clamping sleeve 3332 and the connecting sleeve 3331, passing through the clamping sleeve 3332 to the connecting sleeve 3331, and connected to the second channel 30 on the rotating shaft 332, thereby achieving an adsorption effect.

[0036] like Figure 7 In one embodiment of the present invention, a mounting groove 40 is provided on one end of the connecting sleeve 3331 facing the clamping sleeve 3332, and the clamping sleeve 3332 is slidably arranged in the mounting groove 40. A plurality of grooves arranged at intervals are provided at the bottom of the mounting groove 40, and a first elastic member 336 connected to the clamping sleeve 3332 is provided in each groove. The first channel 20 includes a first sub-channel 21 and a second sub-channel 22, wherein the first sub-channel 21 is provided at the bottom of the mounting groove 40 and extends along the first direction, and the second sub-channel 22 is provided on the clamping sleeve 3332 and extends along the first direction; when the clamping member 333 abuts the battery cell 10, the clamping sleeve 3332 is sealed with the bottom of the mounting groove 40, and the first sub-channel 21 is connected to the second sub-channel 22.

[0037] Specifically, a mounting groove 40 is provided on the end of the connecting sleeve 3331 facing the clamping sleeve 3332. The mounting groove 40 is cylindrical. The outer wall of the clamping sleeve 3332 slides with the inner wall of the mounting groove 40. The clamping sleeve 3332 can slide in the mounting groove 40 along the first direction. The depth of the mounting groove 40 can be designed according to the stroke requirement of the clamping sleeve 3332. In addition, a plurality of spaced grooves are provided at the bottom of the mounting groove 40. These grooves can be arranged in a circle around the axis of the clamping sleeve 3332. A first elastic member 336 is provided in each groove. The first elastic member 336 can be a compression spring. One end of the first elastic member 336 is fixed to the bottom of the groove, and the other end is connected to the end face of the clamping sleeve 3332.

[0038] In addition, the first channel 20 includes a first sub-channel 21 and a second sub-channel 22. The first sub-channel 21 is provided at the bottom of the mounting groove 40 and passes through the connecting sleeve 3331 along the first direction. The end of the first sub-channel 21 away from the clamping sleeve 3332 is connected to the second channel 30. The second sub-channel 22 is provided on the clamping sleeve 3332 and also extends along the first direction. When the clamping sleeve 3332 slides to abut the bottom of the mounting groove 40, the first sub-channel 21 and the second sub-channel 22 are connected, forming the above-mentioned first channel 20. When the clamping member 333 abuts the battery cell 10, the first elastic member 336 can be gradually compressed, and the clamping sleeve 3332 gradually fits tightly against the bottom of the mounting groove 40. At this time, the negative pressure generating device is activated, and the air between the clamping sleeve 3332 and the battery cell 10 is extracted through the first sub-channel 21 and the second sub-channel 22, forming a negative pressure chamber. The above-mentioned structural design enables the clamping sleeve 3332 to float according to the contact situation with the battery cell 10, which not only improves the adaptability of the clamping sleeve 3332 to the surface of battery cells 10 of different specifications, but also can buffer the tiny vibrations generated by the battery cell 10 during clamping or rotation, ensuring that the battery cell 10 is clamped stably and accurately. In addition, the sliding clamping sleeve 3332 design enables the clamping member 333 to adapt to battery cells 10 of different sizes and tolerances, thereby enhancing the versatility and flexibility of the device.

[0039] like Figure 2 and Figure 4 In another embodiment of the present invention, the clamping and rotating mechanism 300 further includes a positioning assembly 350 , which is disposed on the sliding member 310 . The positioning assemblies 350 on the two clamping and rotating mechanisms 300 are relatively telescopic to fix or release the battery cell 10 .

[0040] The positioning assembly 350 is mounted on the sliding member 310, specifically on a side of the sliding member 310 close to the battery cell 10. One positioning assembly 350 can be provided on each clamping and rotating mechanism 300, and two positioning assemblies 350 are arranged opposite each other to form a bidirectional positioning structure for the battery cell 10. The structure of the positioning assembly 350 can be flexibly designed. For example, the positioning assembly 350 can be composed of a positioning block and a telescopic member. The telescopic member can be fixed to the sliding member 310 and can be extended and retracted along a first direction. The positioning block is connected to the telescopic member and moves along the first direction under the drive of the telescopic member. The positioning block can be provided with a plurality of grooves for cooperating with the battery cell 10. After the lifting mechanism lifts the multiple battery cells 10 to the predetermined position, the positioning mechanisms on the two clamping and rotating mechanisms 300 can extend relative to each other, the two positioning blocks approach each other, and the grooves on the two positioning blocks can cooperate with the multiple battery cells 10 to roughly position the positions of the multiple battery cells 10. After that, the lifting assembly can be lowered and detached from the battery cells 10. After that, the two clamping and rotating mechanisms 300 clamp and fix the multiple battery cells 10. After that, the two positioning assemblies 350 retract and detach from the battery cells 10 for subsequent laser cleaning. In the above structure, by setting the positioning assembly 350, the correct position of the battery cell 10 can be ensured before clamping the battery cell 10, thereby ensuring the accuracy of the position of the battery cell 10 clamped by the clamping and rotating assembly, which helps to ensure the processing quality.

[0041] like Figure 4 A structural form of the positioning assembly 350 is shown. In this solution, the positioning assembly 350 includes: A guide member 351 is slidably disposed on the sliding member 310, and the guide member 351 slides along a first direction; The positioning plate 352 is provided on one end of the guide member 351 close to the battery cell 10. The positioning plate 352 is provided with a positioning hole. When the guide member 351 slides toward the battery cell 10, the positioning hole is used to allow the battery cell 10 to penetrate and position the battery cell 10. The second elastic member 353 is provided on the guide member 351 at one end away from the positioning plate 352; The second driving member 354 is disposed on the sliding member 310 and is in transmission connection with the second elastic member 353 .

[0042] The guide member 351 can be a rod-shaped structure extending in a first direction. The sliding member 310 can be provided with a sleeve, with which the guide member 351 can slide and engage, and the guide member 351 can also slide in the first direction. The positioning plate 352 is mounted on the end of the guide member 351 near the battery cell 10. The positioning plate 352 can extend in a second direction. The positioning plate 352 is rectangular and has positioning holes. The shape and size of the positioning holes match the shape of the battery cell 10, and the positions of the positioning holes correspond one-to-one with the positions of the multiple battery cells 10. The second elastic member 353 is disposed on the end of the guide member 351 away from the positioning plate 352. It can be a compression spring and is connected to the end of the guide member 351. The second driving member 354 is mounted on the sliding member 310. It can be a driving device such as a cylinder. The second driving member 354 has a telescopic end that can be extended and retracted in the first direction and is connected to the second elastic member 353. During positioning, the second driving member 354 drives the guide member 351 to slide along the first direction, so that the positioning plate 352 moves toward the battery cell 10. In the process of the battery cell 10 cooperating with the positioning hole, the second elastic member 353 can allow the positioning plate 352 to have a certain floating space, and can prevent hard contact through deformation, thereby ensuring that the battery cell 10 can smoothly penetrate into the positioning hole and preventing damage to the battery cell 10.

[0043] like Figure 9 As shown, in another embodiment of the present invention, the laser cleaning equipment also includes a first detection mechanism 500, which is arranged on one of the clamping and rotating mechanisms 300, and the first detection mechanism 500 is arranged between the rotating shaft 332 and the connecting member 331, and the first detection mechanism 500 is used to detect the rotation state of the rotating shaft 332.

[0044] In this solution, the first detection mechanism 500 is installed on one of the clamping and rotating mechanisms 300, specifically between the rotating shaft 332 and the connecting member 331. The first detection mechanism 500 can be a rotary encoder, which can be connected to the rotating shaft 332 through a coupling to ensure that the rotation of the rotating shaft 332 can be directly transmitted to the encoder. During specific operation, when the rotating shaft 332 drives the clamping member 333 and the battery cell 10 to rotate, the first detection mechanism 500 monitors the rotational movement of the rotating shaft 332 in real time. By judging whether the rotating shaft 332 is rotating and the speed of rotation, it can be determined whether the rotation of the battery cell 10 is normal, thereby ensuring the accuracy and reliability of the rotation control of the battery cell 10 and ensuring the effect of laser cleaning and texturing.

[0045] like Figure 9A structural form of the first detection mechanism 500 is shown. In this scheme, the first detection mechanism 500 includes: a photoelectric sensor 510, which is arranged on the connecting member 331 and has a sensing area; a sensing plate 520, which is arranged on the rotating shaft 332. The sensing plate 520 is coaxially arranged with the rotating shaft 332 and rotates synchronously. The sensing plate 520 is provided with a plurality of protrusions arranged at equal intervals around the axis of the rotating shaft 332. When the rotating shaft 332 rotates, the plurality of protrusions are alternately rotated into the sensing area.

[0046] Among them, the photoelectric sensor 510 is fixed on the connecting part 331. The photoelectric sensor 510 can adopt the conventional slot-type photoelectric structure on the market. The sensing plate 520 is a disc-shaped structure. The edge of the sensing plate 520 is provided with multiple equally spaced notches. The sensing plate 520 is coaxially connected to the rotating shaft 332. When the rotating shaft 332 rotates, multiple notches periodically pass through the photoelectric sensor 510. By sensing multiple notches, it can be determined whether the rotating shaft 332 is rotating and the rotation speed, thereby determining the rotation state of the battery cell 10.

[0047] In addition, if Figure 5 In another embodiment of the invention, the driving assembly 340 adopts the form of a magnetic shaft 342 driving a magnetic wheel 343. The magnetic shaft 342 is rotatably set on the sliding member 310 and extends along the first direction. A power member 341 is also provided on the sliding member 310. The power member 341 is connected to the magnetic shaft 342 through a belt drive. A plurality of permanent magnets are embedded in the magnetic shaft 342. These permanent magnets are along the circumference of the magnetic shaft 342, and the magnetic poles change alternately; a magnetic wheel 343 is provided on each rotating shaft 332. The magnetic wheel 343 is embedded with a permanent magnet and can rotate with the magnetic shaft 342. The permanent magnets on the servo drive 341 are coupled, and the magnetic wheel 343 is installed on the rotating shaft 332 by a coaxial connection. When the servo power part 341 drives the magnetic shaft 342 to rotate, the permanent magnets on the magnetic shaft 342 generate a rotating magnetic field, which interacts with the magnetic material on the magnetic wheel 343 to generate magnetic coupling. Driven by the magnetic field, the magnetic wheel 343 drives the rotating shaft 332 to rotate synchronously. In this solution, since the magnetic shaft 342 and the magnetic wheel 343 perform non-contact transmission through the magnetic field, the friction and wear problems in traditional mechanical transmission are avoided, and the reliability and service life of the device are improved.

[0048] In addition, in this solution, the permanent magnet on the magnetic axis 342 extends along the axial direction of the magnetic axis 342 to both ends of the magnetic axis 342, so that a continuous and uniform magnetic field can be formed in the axial direction of the magnetic axis 342; in addition, a slide groove extending along the second direction is provided on the sliding member 310, and the length and width of the slide groove are designed according to actual adjustment requirements. One end of the connecting member 331 in the clamping terminal 330 is in the shape of a rectangular parallelepiped and embedded in the slide groove, and slides along the extension direction of the slide groove. A plurality of screw holes spaced along the second direction are provided on both sides of the slide groove, and the spacing of the screw holes is set according to actual adjustment requirements. The connecting member 331 is connected to the screw hole by screws, thereby fixing its position on the sliding member 310. With the above-mentioned structural design, when the clamping terminal 330 needs to be replaced, the clamping terminal 330 can be removed from the connecting piece 331 by simply loosening the screws, and replaced with a clamping terminal 330 of other specifications or the number of clamping terminals 330 can be changed, thereby improving versatility; in addition, the connecting piece 331 moves in the slide groove to adjust the spacing between the clamping terminals 330, and when the clamping terminal 330 is in any position, the magnetic shaft 342 and the magnetic wheel 343 always remain in coordination, and the magnetic shaft 342 can always drive the magnetic wheel 343 to rotate, so that it can adapt to the clamping requirements of battery cells 10 of different specifications, and the number and position of the rotating shaft 332 can also be adjusted according to actual needs, thereby improving the flexibility of the use of the device.
