Description

Technical Field

[0001] This application relates to the field of battery technology, and more particularly to a kneading device. Background Technology

[0002] The tabs are crucial components connecting the internal electrodes (positive and negative) of a battery to the external circuitry. Tab forming is one of the key processes in battery manufacturing, and its quality directly impacts the battery's electrical performance, safety, and reliability. To further improve the quality of tab forming, it is necessary to optimize the physical morphology and structural stability of the tabs to ensure the reliability and overall performance of subsequent battery processes.

[0003] In related technologies, the tabs of the core are flattened by rotating a flattening wheel. During this process, a large frictional force is generated between the tabs and the flattening wheel, which easily produces metal shavings. Utility Model Content

[0004] This application provides a kneading device to at least partially solve the above-mentioned technical problems.

[0005] To achieve the above objectives, according to a first aspect of this application, a kneading device is provided, comprising: an installation mechanism for installing a core and for driving the core to rotate;

[0006] The kneading mechanism includes a drive component and a kneading wheel. The drive component can drive the kneading wheel to move so that the kneading wheel kneads the core.

[0007] With this configuration, the core can rotate under the drive of the mounting mechanism, and the flattening wheel can move under the drive of the drive component. This ensures that there is a small relative movement between the flattening wheel and the core during the flattening process, which helps to reduce the friction between the flattening wheel and the core.

[0008] Optionally, the mounting mechanism includes a mounting member for mounting the winding core, and the driven mounting member can drive the winding core to rotate.

[0009] This design allows for minimal relative movement between the kneading roller and the core during the kneading process, which helps reduce friction between them.

[0010] Optionally, the mounting mechanism includes a first driving member, which is drivingly connected to the mounting member.

[0011] The first driving component can drive the mounting component to rotate, thereby driving the core to rotate.

[0012] Optionally, the driving assembly includes a second driving member connected to the kneading wheel for driving the kneading wheel to rotate.

[0013] Optionally, there are multiple kneading rollers and multiple second driving members, with one kneading roller cooperating with at least one second driving member.

[0014] In this way, each smoothing roller is driven by at least one second drive component, so when one smoothing roller stops working, it does not affect the operation of other smoothing rollers. Moreover, multiple smoothing rollers can complete the smoothing of the core more quickly, improving smoothing efficiency.

[0015] Optionally, the driving component includes a turntable, and the kneading wheel is mounted on the turntable and can move under the drive of the turntable.

[0016] Optionally, the driving assembly includes a third driving member connected to the turntable drive for driving the turntable to rotate, so that the kneading wheel rotates about the axis of the turntable.

[0017] Optionally, the kneading equipment has a first working condition, a second working condition, and a third working condition.

[0018] When the kneading and smoothing equipment is in the first working condition, the kneading and smoothing wheel rotates, and the core rotates.

[0019] When the kneading and smoothing equipment is in the second working condition, the kneading and smoothing wheel rotates, and the turntable rotates.

[0020] When the kneading and smoothing equipment is in the third working condition, the kneading and smoothing wheel rotates, the core rotates, and the turntable rotates.

[0021] Optionally, when the kneading equipment is in the third operating condition,

[0022] The rotation direction of the flattening wheel and the turntable is configured to be the same as the rotation direction of the core; and / or, the rotation speed of the flattening wheel and the turntable is configured to be the same as the rotation speed of the core. This results in a smaller relative speed difference between the core and the flattening wheel, reducing friction between them and thus improving wear on the end face tabs.

[0023] Optionally, when the leveling device is in the third operating condition, the rotational speed of the leveling wheel ranges from 10 degrees / second to 1000 degrees / second. This results in suitable friction between the leveling wheel and the core, which on the one hand allows the leveling wheel to level the tabs of the core, and on the other hand reduces wear on the end face of the core during the leveling process, thus reducing the generation of metal shavings.

[0024] Optionally, the kneading device further includes a conveying module connected to the kneading mechanism, used to drive the kneading mechanism closer to or further away from the mounting mechanism. This allows for adjustment of the distance between the kneading rollers of the kneading mechanism and the core held by the mounting mechanism.

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0040] Firstly, please combine Figure 1 and Figure 4 This application provides a kneading device 1. In some embodiments, the kneading device 1 includes a kneading mechanism 10 and a mounting mechanism 30. The mounting mechanism 30 is used to mount the core 2 and to drive the core 2 to rotate. The kneading mechanism 10 includes a drive assembly 101 and a kneading wheel 13. The drive assembly 101 can drive the kneading wheel 13 to move so that the kneading wheel 13 kneads the core 2.

[0041] In this embodiment, the core 2 can rotate under the drive of the mounting mechanism 30, and the flattening wheel 13 can move under the drive of the drive assembly 101. By adjusting the movement speed of the core 2 and the flattening wheel 13 respectively, a small relative movement can be maintained between the flattening wheel 13 and the core 2 during the flattening process, which can help reduce the friction between the flattening wheel 13 and the core 2.

[0042] Please combine Figure 5 The mounting mechanism 30 is used to mount the core 2. The mounting mechanism 30 can clamp the core 2, thereby mounting the core 2 onto the mounting mechanism 30. The mounting mechanism 30 can clamp the middle of the core 2, leaving the tabs 21 at both ends of the core 2 exposed. In one example, please conclude... Figure 1 A flattening mechanism 10 can be provided at one end of the core 2. The flattening mechanism 10 is used to flatten the tabs 21 of the core 2. In one example, a flattening mechanism 10 is provided at each of the opposite ends of the core 2. The flattening mechanisms 10 on both sides flatten the tabs 21 at the opposite ends of the core 2. The mounting mechanism 30 can drive the core 2 to rotate, and the flattening wheel 13 can move under the drive of the drive assembly 101 so that the flattening wheel 13 can flatten the core 2.

[0043] Please combine Figure 1 The kneading device 1 also includes a conveying module 50, and the kneading mechanism 10 is connected to the conveying module 50. The kneading mechanism 10 can move closer to or further away from the mounting mechanism 30 under the drive of the transmission module.

[0044] In some embodiments, the flattening mechanism 10 can move along a first direction under the drive of the transmission module, thereby approaching or moving away from the mounting mechanism 30 to adjust the distance between the flattening mechanism 10 and the mounting mechanism 30, so that the flattening wheel 13 can contact the core 2 and flatten the tabs 21 of the core 2. Since the mounting mechanism 30 is mainly used to clamp the core 2, this arrangement allows the flattening wheel 13 of the flattening mechanism 10 to move closer to or away from the end of the core 2, or the tabs 21 of the core 2, by controlling the movement of the flattening mechanism 10, thereby adjusting the distance between the flattening wheel 13 of the flattening mechanism 10 and the core 2 clamped by the mounting mechanism 30. In some embodiments, the conveying module 50 can drive the flattening mechanism 10 to move in a straight line, approaching or moving away from the mounting mechanism 30.

[0045] Please combine Figure 2 The driving component 101 includes a second driving member 12, which is connected to the kneading wheel 13 and is used to drive the kneading wheel 13 to rotate.

[0046] In one example, the kneading wheel 13 can be a cone, and the rotation of the kneading wheel 13 can refer to the rotation of the kneading wheel 13 about its own axis. The second driving member 12 may include a drive motor, which is used to drive the kneading wheel 13 to rotate about its own axis.

[0047] There are multiple kneading rollers 13 and multiple second driving members 12, with each kneading roller 13 cooperating with at least one second driving member 12. Thus, each kneading roller 13 is driven by at least one second driving member 12, and when one kneading roller 13 stops working, it does not affect the operation of the other kneading rollers 13. Furthermore, multiple kneading rollers 13 can complete the kneading of the core 2 more quickly, improving kneading efficiency.

[0048] The drive assembly 101 includes a turntable 15, and the kneading wheel 13 is mounted on the turntable 15 and can move under the drive of the turntable 15.

[0049] The drive assembly 101 includes a third drive member 14, which is drivenly connected to the turntable 15 and is used to drive the turntable 15 to rotate, so that the kneading wheel 13 rotates around the axis of the turntable 15.

[0050] In one example, the cross-section of turntable 15 along the vertical axis can be circular, and the rotation of turntable 15 can refer to the rotation of turntable 15 about the axis of turntable 15.

[0051] In one example, the third drive 14 drives the shaft 17 via the timing belt 16, which in turn drives the turntable 15 to rotate.

[0052] The third driving member 14 is used to drive the turntable 15 to rotate around the axis of the turntable 15. The second driving member 12 and the kneading wheel 13 are mounted on the turntable 15, so that the rotating turntable 15 can drive the second driving member 12 and the kneading wheel 13 mounted on the turntable 15 to rotate around the axis of the turntable 15. The third driving member 14 may include a drive motor.

[0053] In this embodiment, the flattening wheel 13 can have three states. In the first state, the flattening wheel 13 rotates around its axis under the drive of the second driving member 12. In the second state, the turntable 15 rotates, that is, the turntable 15 rotates around its axis. The flattening wheel 13 rotates around its axis under the drive of the turntable 15. In the second state, when the flattening wheel 13 is not driven by the second driving member 12, the flattening wheel 13 can rotate freely around its axis. Thus, when the flattening wheel 13 contacts the tab 21 of the core 2, and when there is relative friction between the flattening wheel 13 and the core 2, the flattening wheel 13 can rotate around its axis. In the third state, the flattening wheel 13 rotates around its axis under the drive of the second driving member 12, and simultaneously rotates around its axis under the drive of the turntable 15.

[0054] Please combine Figure 3 The mounting mechanism 30 includes a mounting member 31 for mounting the core 2. The driven mounting member 31 can drive the core 2 to rotate. The core 2 can rotate under the drive of the mounting mechanism 30, and the kneading wheel 13 can rotate under the drive of the drive assembly 101. In this way, during the kneading process, a small relative movement can be maintained between the kneading wheel 13 and the core 2, which helps to reduce the friction between the kneading wheel 13 and the core 2.

[0055] The mounting mechanism 30 includes a first driving member 32, which is drivenly connected to the mounting member 31. The mounting member 31 is used to clamp the winding core 2, and the first driving member 32 is drivably connected to the mounting member 31 to drive the mounting member 31 to rotate, thereby driving the winding core 2 to rotate. In one example, the winding core 2 is the winding core 2 of a cylindrical battery, and the rotation of the winding core 2 refers to the rotation of the winding core 2 about its axis. In some embodiments, the first driving member 32 may drive the mounting member 31 to rotate via a coupling.

[0056] The following describes several working conditions of the kneading equipment 1 in the embodiments of this application. The kneading equipment 1 includes a first working condition, a second working condition, and a third working condition.

[0057] When the kneading device 1 is in the first working condition, the kneading wheel 13 rotates and the core 2 rotates. In the first working condition, the second drive component 12 and the first drive component 32 are working, and the third drive component 14 is not working. That is, the kneading wheel 13 rotates (the kneading wheel 13 rotates around the axis of the kneading wheel 13) and the core 2 rotates (the core 2 rotates around the axis of the core 2), thereby achieving the kneading of the tabs 21 of the core 2.

[0058] In the first working condition, the rotation direction of the flattening wheel 13 around its axis can be the same as the rotation direction of the core 2 around its axis. For example, in one example, the flattening wheel 13 can rotate clockwise, and the core 2 can rotate clockwise; or in another example, the flattening wheel 13 can rotate counterclockwise, and the core 2 can rotate counterclockwise. The rotation speed of the flattening wheel 13 is the same as the rotation speed of the core 2. The rotation speed can be in the range of 5 degrees / second to 5000 degrees / second, for example, 5 degrees / second, 100 degrees / second, 500 degrees / second, 1000 degrees / second, 2000 degrees / second, 3000 degrees / second, 4000 degrees / second, 4500 degrees / second, and 5000 degrees / second.

[0059] In the second operating condition, the second driving component 12 and the third driving component 14 are working, while the first driving component 32 is not working. This means that the kneading wheel 13 rotates (rotates around its axis), and the turntable 15 rotates (rotates around its axis). The kneading wheel 13 can also rotate around its axis under the drive of the turntable 15. In this second operating condition, the rotation direction of the kneading wheel 13 (rotates around its axis) can be the same as the rotation direction of the turntable 15 (rotates around its axis). For example, in one example, the kneading wheel 13 can rotate clockwise, and the turntable 15 can rotate clockwise; or in another example, the kneading wheel 13 can rotate counterclockwise, and the turntable 15 can rotate counterclockwise. The rotational speed of the kneading wheel 13 is the same as the rotational speed of the turntable 15.

[0060] In the third operating condition, the second drive component 12, the third drive component 14, and the first drive component 32 all operate. That is, the kneading wheel 13 can rotate under the drive of the second drive component 12 (the kneading wheel 13 rotates around its axis). The third drive component 14 can drive the turntable 15 to rotate (the turntable 15 rotates around its axis), thus the rotating turntable 15 can drive the second drive component 12 and the kneading wheel 13 mounted on the turntable 15 to rotate around its axis. Simultaneously, the core 2 rotates (the core 2 rotates around its axis). In the third operating condition, the rotation directions of the flattening wheel 13 around its axis, the rotation directions of the turntable 15 around its axis, and the rotation directions of the core 2 around its axis are the same. For example, in one example, the flattening wheel 13 can rotate clockwise, the turntable 15 can rotate clockwise, and the core 2 can rotate clockwise; or in another example, the flattening wheel 13 can rotate counterclockwise, the turntable 15 can rotate counterclockwise, and the core 2 can rotate counterclockwise. The rotational speeds of the flattening wheel 13, the turntable 15, and the core 2 are the same. This results in a smaller relative speed difference between the core 2 and the flattening wheel 13, reducing friction between them and thus improving the wear of the end face tabs 21. When the kneading device 1 is in the third operating condition, the rotational speed of the core 2 can range from 10 degrees / second to 1000 degrees / second, for example, 10 degrees / second, 100 degrees / second, 500 degrees / second, and 1000 degrees / second. This results in suitable friction between the kneading roller 13 and the core 2, enabling the kneading roller 13 to knead the tabs 21 of the core 2, and reducing wear on the end face of the core 2 during the kneading process, thus reducing the generation of metal shavings. In the third operating condition, when the core 2 has a lower rotational speed, a smaller relative speed difference can be achieved between the core 2 and the kneading roller 13, reducing friction between them.

[0061] The conveying module 50 may include a slide rail and a slider, with the slider capable of sliding along the slide rail. The flattening mechanism 10 may be fixed to the slider of the conveying module 50. By controlling the slider to slide along the slide rail, when the slotted photoelectric sensor detects that the slider has reached its position, it controls the slider to stop, and the flattening wheel 13 begins to flatten the end face of the core 2 (specifically, flattening the tab 21 of the core 2). After flattening is completed, the slider returns to its initial state. The stroke of the slider may be controlled by a PLC. After flattening, the stroke of the slider returning from the flattening position is the feed amount of the slider, and the position where the slider returns is the initial position of the slider.
