[0047] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0048] Reference Figure 1 This application provides a winding device, which includes:

[0049] Support base 2, support base 2 is used for installation onto the large plate;

[0050] Rotating structure 3 has a feeding station. Rotating structure 3 includes flange assembly 31 and needle coil assembly 32. Flange assembly 31 is rotatably connected to support base 2, and needle coil assembly 32 is connected to flange assembly 31.

[0051] Insertion and removal assembly 4 is disposed on support base 2 and close to the unloading station. Insertion and removal assembly 4 is configured to drive needle coil assembly 32 to move axially thereon.

[0052] In one embodiment, the winding device may include a base 1, and a support 2 is mounted on the base 1 and can pass through the large plate; the base 1 can serve as the basic structure of the winding device to provide installation positions and stable support for other structures on the winding device; moreover, during the rotation and movement of some structures in the winding device, the base 1 can provide a stable and reliable operating environment to ensure the stable operation of the winding device.

[0053] In this embodiment, the large plate provides structural support, an operating platform, and sheet transport and positioning functions for the winding device. The support base 2 is installed on the base 1, ensuring the stability of the support base 2. The support base 2 passes through the large plate and can extend to both sides of the large plate, providing support for the rotating structure 3 on both sides of the large plate, so that the needle winding assembly 32 can move from one side of the large plate to the other side of the large plate.

[0054] See Figure 1 The rotating structure 3 is rotatably connected to the support base 2 and has a winding station, an adhesive application station, and a blanking station. For example, when the rotating structure 3 rotates to the winding station, the winding needle assembly 32 can wind the electrode sheet and the separator to ensure the tight fit between the electrode sheet and the separator, so as to obtain a bare battery cell with a certain thickness and structure. When the rotating structure 3 rotates to the adhesive application station, the rotating structure 3 conveys the wound bare battery cell to the bottom of the adhesive application or adhesive application device so as to apply glue or tape at the adhesive application position of the battery cell.

[0055] When the rotating structure 3 rotates to the unloading station, the battery cell wound on the needle winding assembly 32 can be removed to facilitate subsequent assembly or testing. For example, the battery cell can be removed from the needle winding assembly 32 by a robotic arm, suction cup, or other tools. To facilitate the robotic arm or suction cup in obtaining the battery cell, the needle winding assembly 32 can be moved axially by the insertion and removal assembly 4, so that the needle winding assembly 32 is moved to a position that facilitates the unloading of the battery cell, making it easier for the battery cell to detach from the needle winding assembly, thus improving the unloading efficiency of the needle winding assembly 32.

[0056] Two, three, or more sets of needle coil assemblies 32 can be connected to the flange assembly 31. In a specific embodiment, three sets of needle coil assemblies 32 are connected at equal intervals on the flange assembly 31. When one set of needle coil assemblies 32 rotates to the unloading station, the other two sets of needle coil assemblies 32 are located at the winding station and the adhesive application station, respectively, so as to realize the simultaneous winding, adhesive application, and unloading, thereby improving the working efficiency of the winding device.

[0057] See Figure 1By mounting the insertion / removal assembly 4 on the support base 2, the stability of the insertion / removal assembly 4 can be ensured. Simultaneously, by placing a set of insertion / removal assemblies 4 near the unloading station, the insertion / removal assembly 4 is prevented from being mounted on the rotating structure 3 and rotating with it. The insertion / removal assembly 4 can then push the needle coiling assembly 32 located at the unloading station to extend out of the large plate or retract into the large plate. (See [reference]). Figure 2a The left side of the large plate 200 can be its inner side, and the right side of the large plate 200 can be its outer side. While simplifying the structure, it ensures stable and precise driving of the insertion and removal assembly 4 to the winding needle assembly 32, and improves the efficiency and accuracy of the winding device in feeding the sheet.

[0058] In one embodiment, see Figure 1 The needle winding assembly 32 includes a rotating component 321 and a needle winding 322. The rotating component 321 is connected to the flange assembly 31 and is used to drive the needle winding 322 to rotate.

[0059] In this embodiment, connecting the rotating component 321 and the winding needle 322 via the flange assembly 31 enhances the structural stability of the entire winding needle assembly 32. Simultaneously, the winding needle 322 is connected to the output end of the rotating component 321, allowing the rotating component 321 to drive the winding needle 322 to rotate, thereby achieving the winding of the sheet material wound on the winding needle 322 and ensuring the winding efficiency of the sheet material.

[0060] In one embodiment, see Figure 1 The winding device also includes a revolution component 5, which is connected to the rotating structure 3 and is used to drive the rotating structure 3 to rotate.

[0061] When the rotating structure 3 rotates to the unloading station, the plugging and unplugging assembly 4 cooperates with the self-rotating component 321 to allow the coiling needle 322 to switch between the two sides of the large plate.

[0062] In this embodiment, the revolving component 5 can drive the rotating structure 3 to rotate, so that the coiling needle assembly 32 on the flange assembly 31 can switch between the winding station, the adhesive application station and the unloading station, thereby realizing continuous operation of sheet winding, adhesive application and unloading.

[0063] When the rotating structure 3 rotates to the unloading station, the self-rotating component 321 rotates to a position close to the insertion and removal component 4 and cooperates with the insertion and removal component 4. The movement of the insertion and removal component 4 can drive the self-rotating component 321 and the winding needle 322 to move together, so as to realize the rapid switching of the winding needle 322 on both sides of the large plate.

[0064] In some embodiments, see Figure 1 and Figure 4The insertion and removal assembly 4 includes a driving member 41, a transmission member 42, and a toggle member 43. The rotating part 321 of the needle winding assembly 32 has a mating member 3211. One end of the transmission member 42 is connected to the output end of the driving member 41, and the other end of the transmission member 42 is connected to the toggle member 43. The driving member 41 can drive the transmission member 42 to move along the axial direction of the needle winding assembly 32, so as to drive the needle winding 322 to move when the mating member 3211 and the toggle member 43 are engaged, for example, to drive the needle winding 322 to switch between the two sides of the large plate.

[0065] In the above embodiments, the engagement between the mating member 3211 and the actuating member 43 can be a snap-fit ​​engagement or a magnetic engagement, so as to ensure the synchronous movement of the actuating member 43 and the mating member 3211.

[0066] The drive unit 41 can be a motor or a cylinder. The drive unit 41 can quickly respond to the control signal and drive the toggle unit 43 to move rapidly through the movement of the transmission unit 42, so as to realize the rapid switching of the position of the winding needle 322.

[0067] In one embodiment, see Figure 4 The plug-in assembly 4 includes a connector 44, which is fixed to the support base 2. The transmission component 42 is mounted on the connector 44 to facilitate the connection of both ends of the transmission component 42 with the drive component 41 and the actuating component 43.

[0068] In another embodiment, the transmission component 42 is a lead screw and nut component. The transmission component 42 specifically includes a lead screw and a nut. The lead screw is connected to the drive component 41. The nut is sleeved on the lead screw and connected to the actuating component 43. While the drive component 41 drives the lead screw to rotate, it can make the nut move along the axial direction of the needle winding assembly 32, thereby driving the movement of the actuating component 43 to realize the position switching of the needle winding 322.

[0069] In one embodiment, see Figure 1 and Figure 4 The actuating element 43 has a slot, and the mating element 3211 has a protrusion that engages with the slot.

[0070] In this embodiment, the actuating member 43 may have a slot with an opening facing the unloading station. When the rotating structure 3 is rotated to the unloading station, the protrusion on the mating member 3211 can be inserted into the slot. When the driving member 41 is activated, the actuating member 43 and the protrusion can be used to drive the winding needle assembly 32 to move, so as to achieve the purpose of the winding needle 322 extending out of the outer side of the large plate or retracting into the inner side of the large plate.

[0071] In one embodiment, see Figure 4 The plug-in assembly 4 includes a pneumatic component 45, and the actuating component 43 is connected to the transmission component 42 through the pneumatic component 45;

[0072] The pneumatic component 45 is used to drive the actuating component 43 to move closer to or away from the needle winding assembly 32.

[0073] In the above embodiments, the pneumatic component 45 can be a cylinder or an air pump. The pneumatic component 45 can provide precise and repeatable motion control and has a fast response speed, so that the actuating component 43 can be moved very accurately to the position where it needs to engage with the mating component 3211, ensuring the efficiency and accuracy of the connection between the insertion and extraction assembly 4 and the coiling needle assembly 32.

[0074] In some embodiments, see Figure 1 and Figure 3 The rotating component 321 of the needle winding assembly 32 includes a needle winding support 3212 and a magnetic suction member 3213. The needle winding support 3212 is slidably connected to the flange assembly 31 in the axial direction of the needle winding assembly 32, and the magnetic suction member 3213 is disposed on the needle winding support 3212.

[0075] When the needle coil assembly 32 moves axially to the target position, the magnetic attractor 3213 magnetically engages with the flange assembly 31.

[0076] In the above embodiments, see Figure 3 A magnetic suction element 3213 can be fixedly installed on the needle winding support seat 3212 of the self-rotating component 321. When the insertion and removal component 4 drives the needle winding assembly 32 to move in its axial direction and makes the needle winding assembly 32 in a target position that is convenient for unloading, it is attracted to the flange assembly 31 made of magnetic material by the magnetic suction element 3213, which ensures the stability of the relative position between the needle winding assembly 32 and the flange assembly 31 and prevents the needle winding assembly 32 from shifting during rotation.

[0077] In the above embodiments, the number of magnetic components 3213 on the needle coil support 3212 can be multiple. By having multiple magnetic components 3213 simultaneously attract the flange assembly 31, the stability of the needle coil assembly 32 at the target position is improved.

[0078] In some embodiments, the magnetic attractor 3213 can be a permanent magnet or an electromagnet. When the magnetic attractor 3213 is an electromagnet, the electromagnet can be magnetically attracted to the flange assembly 31 by energizing the electromagnet, and the fixation of the needle coil assembly 32 can be released by de-energizing the electromagnet, which facilitates the flexible movement of the needle coil assembly 32.

[0079] In one embodiment, see Figure 3 A buffer 3214 is provided on the needle coil support 3212. The buffer 3214 can be an elastomer such as rubber or plastic to avoid hard contact between the rotating part 321 and the flange assembly 31 and ensure the structural integrity of the flange assembly 31.

[0080] In some embodiments, see Figure 1 The winding device also includes a clamping power assembly 6, which is connected to the support base 2. The clamping power assembly 6 is configured to hold the winding needle 322. The diameter of the winding needle 322 can change when it is held. For example, when the winding needle 322 is wound with a roll of material, the stability of the roll of material on the winding needle 322 can be ensured by increasing the diameter of the winding needle 322; and the unloading of the roll of material on the winding needle 322 can be facilitated by decreasing the diameter of the winding needle 322.

[0081] In some embodiments, see Figure 1 , Figure 2a and Figure 2b The winding device also includes a stop assembly 7;

[0082] The stop assembly 7 includes a connecting rod 71, an elastic element 72, and a stop block 73. The connecting rod 71 can pass through the large plate. The elastic element 72 is located between one end of the connecting rod 71 and the side of the large plate near the rotating component 321. The stop block 73 is connected to the other end of the connecting rod 71 and is located on the side of the large plate away from the rotating component 321, so as to ensure the positional stability of the winding needle 322 when the stop block 73 abuts against the large plate 200.

[0083] In some embodiments, see Figure 1 , Figure 2a and Figure 2b When the insertion and removal assembly 4 drives the coil needle 322 to extend to the side of the large plate away from the rotating component 321, the magnetic suction component 3213 abuts against the connecting rod 71, and the elastic component 72 is clamped between one end of the connecting rod 71 and the side of the large plate close to the rotating component 321.

[0084] When the clamping power assembly 6 holds the winding needle 322 to adjust the diameter of the winding needle 322, the stop block 73 stops the large plate on the side away from the rotating component 321.

[0085] In the above embodiments, see Figure 1 , Figure 2a and Figure 5 The left side of the large plate 200 can be its inner side, and the right side of the large plate 200 can be its outer side. The rotating component 321 is located on the inner side of the large plate 200 and can drive the coiling needle 322 to switch between the outer and inner sides of the large plate 200. When the clamping power component 6 applies axial compressive force to the coiling needle 322, it can reduce the diameter of the coiling needle 322, making it easier to unload the sheet material wound on the coiling needle 322.

[0086] To prevent the needle coil 322 from moving along its axial direction when the clamping power assembly 6 squeezes the needle coil 322, which would cause the magnetic suction component 3213 of the rotating component 321 to detach from the flange assembly 31, a stop assembly 7 can be set to stop the rotating component 321 and ensure the positional stability of the needle coil 322.

[0087] See Figure 1 and Figure 2a The connecting rod 71 of the stop assembly 7 is slidably connected to the large plate 200. One end of the connecting rod 71 is fitted with an elastic element 72 such as a spring or elastic sleeve between it and the large plate 200. The other end of the connecting rod 71 is fixed with a stop block 73 such as a clamp or nut. Under the elastic action of the elastic deformation of the elastic element 72, the stop block 73 abuts against the large plate 200.

[0088] When the insertion and removal assembly 4 drives the coil needle 322 to extend to the side of the large plate away from the rotating component 321, the magnetic suction component 3213 of the rotating component 321 abuts against one end of the connecting rod 71, at which time the elastic component 72 is compressed; when the clamping power assembly 6 holds the coil needle 322 to adjust the diameter of the coil needle 322, the stop block 73 abuts against the large plate 200 again, so that the coil needle 322 will not move axially when the clamping power assembly 6 pushes the coil needle 322, at which time the elastic force of the elastic component 72 can ensure the stability of the stop block 73 abutting against the large plate 200.

[0089] In a specific embodiment, such as Figure 1 As shown, a needle winding assembly 32 is provided with two sets of stop assemblies 7. The two sets of stop assemblies 7 are symmetrically arranged on both sides of the needle winding assembly 32, ensuring that the needle winding 322 can be stably clamped.

[0090] In some embodiments, see Figure 1 and Figure 5 The winding device also includes a support assembly 8, and the flange assembly 31 includes a first flange 311, a second flange 312 and a slide rod 313. The slide rod 313 is connected between the first flange 311 and the second flange 312 and is located on both sides of the large plate with the support assembly 8 respectively.

[0091] The rotating component 321 is slidably connected to the slide bar 313, and the side of the needle winding assembly 32 away from the rotating component 321 is connected to the support assembly 8.

[0092] In this embodiment, the slide bar 313 serves as a bridge connecting the first flange 311 and the second flange 312, ensuring a stable connection between them and providing a sliding track for the rotating component 321, allowing it to move smoothly on the slide bar 313. Simultaneously, the synergistic effect of the support assembly 8 and the flange assembly 31 provides stable support for both ends of the needle coil assembly 32.

[0093] In some embodiments, see Figure 1 and Figure 5 The support assembly 8 includes a support plate 81 and a support member 82. The support member 82 is disposed on the support plate 81 and can hold the coil needle 322 by clamping the power assembly 6.

[0094] The support member 82 includes a movable shaft 821 and a brake 822, which can fix the position of the movable shaft 821.

[0095] In this embodiment, the support member 82 includes a support base, and the movable shaft 821 and the brake 822 can both be disposed on the support base; the change in the extension and retraction of the movable shaft 821 on the support member 82 can adjust the diameter of the winding needle 322, ensuring the controllability of the change in the diameter of the winding needle 322.

[0096] Specifically, see Figure 1 and Figure 5 The moving end of the clamping power component 6 drives the moving shaft 821 to move on the support plate 81, thereby quickly adjusting the holding force of the support member 82 on the coil needle 322. At this time, the diameter of the coil needle 322 changes, so that the support member 82 can adapt to different specifications of coil needle 322, improving the efficiency of coil needle 322 adjustment.

[0097] When the moving shaft 821 holds the coil needle 322, the position of the moving shaft 821 can be fixed by the action of the brake 822. At this time, the moving end of the clamping power assembly 6 can be reset, preventing the clamping power assembly 6 from constantly pressing against the support member 82.

[0098] When the sheet wound on the needle 322 needs to be unloaded, the brake 822 can release the fixation on the moving shaft 821. The moving shaft 821 automatically resets and moves away from the needle 322 under the action of the spring, making the diameter of the needle 322 smaller, which facilitates the unloading of the wound sheet from the needle 322.

[0099] In some embodiments, see Figure 1 and Figure 5 The winding device also includes a reset member 9, which is connected to the clamping power assembly 6 via a pull plate 91.

[0100] When the support member 82 releases the winding needle 322, the reset member 9 is configured to pull the moving shaft 821 away from the winding needle 322.

[0101] See Figure 1 and Figure 5 To ensure that the movable shaft 821 is reliably reset, a reset component 9 is also provided on the support base 2. The reset component 9 drives the pull plate 91 to move the movable shaft 821 so that the movable shaft 821 is away from the winding needle 322.

[0102] In one specific embodiment, the action of the reset member 9 can be linked with the release of the coil needle 322 by the support member 82.
