Description

Technical Field

[0001] This application relates to the field of battery cell manufacturing technology, and in particular to an angle-adjustable battery cell leveling mechanism. Background Technology

[0002] During the cell production process, burrs, wrinkles, or slight deformations may occur at the edges of the electrodes and separators due to cutting or other reasons. This can lead to uneven internal stress in the cell, affect battery density, or cause separator puncture.

[0003] To address the aforementioned material edge defects, a common solution is to press or heat the edges of the electrode and diaphragm using contact blocks to flatten or soften the edges, thereby creating smooth edges.

[0004] When the angle of a contact block needs to be adjusted due to process requirements, it is usually done by adjusting the angle of a single contact block. However, due to production efficiency requirements, multiple contact blocks are set up on the production line to press the edges of multiple materials simultaneously. This means that when the angle of a contact block needs to be adjusted, the angles of multiple contact blocks must be adjusted separately, which is a cumbersome and inefficient process.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments in this application specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application.

Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0061] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0062] Please see Figures 1 to 3 An adjustable-angle battery cell leveling mechanism provided in this application embodiment includes: a leveling component 10 and a flipping component 20; the leveling component 10 includes: a support member 11 and a plurality of contact blocks 12 disposed on the support member 11; the flipping component 20 includes: a driving member 21 and a first guide block 22; the first guide block 22 is provided with an arc-shaped groove 23; the support member 11 is provided with a sliding block 14; the sliding block 14 is movably disposed in the arc-shaped groove 23; the driving member 21 is used to drive the support member 11 and the first guide block 22 to slide relative to each other so that the sliding block 14 moves along the arc-shaped groove 23; when the sliding block 14 moves along the arc-shaped groove 23, the leveling component 10 flips.

[0063] In this embodiment, multiple contact blocks 12 can be provided on the support member 11; when the support member 11 is flipped, it will drive the multiple contact blocks 12 to flip synchronously. The contact blocks 12 can be pressing blocks used to press the edges of materials such as electrode sheets and diaphragms, or they can be hot pressing blocks with heating function.

[0064] In practical applications, the leveling component 10 or the flipping component 20 can be mounted on the support structure to provide support and guidance for the angle-adjustable cell leveling mechanism. The leveling action of the contact block 12 can be driven by the entire support structure; for example, the entire support structure can move linearly to approach or move away from the material, thereby driving the contact block 12 to contact or move away from the material. Specifically, the driving method for the leveling action of the contact block 12 can be the same as that of existing contact blocks; therefore, the relevant structure is not shown in the illustrations provided in this application embodiment.

[0065] In this embodiment, when the drive unit 21 is activated, the first guide block 22 and the sliding block 14 will move relative to each other along the first direction x, thereby pushing the sliding block 14 to move along the arcuate groove 23, so that the leveling assembly 10 will move at least along the direction perpendicular to the first direction x. In order to make the leveling assembly 10 flip, in addition to the pushing force of the first guide block 22, the leveling assembly 10 will also be subjected to other forces to produce the flipping. In the embodiments of this application, the following implementation methods that enable the leveling assembly 10 to flip are provided.

[0066] As one implementation method, please refer to Figure 4 The aforementioned support structure may be provided with a limiting groove 30; the limiting groove 30 is also arc-shaped. A second sliding block 15 is provided on the support member 11, and the second sliding block 15 is slidably disposed within the limiting groove 30. When the first guide block 22 moves linearly, the sliding block 14 moves along the arc-shaped groove 23, while the second sliding block 15 moves along the limiting groove 30, causing the support member 11 to undergo a flipping motion.

[0067] In this embodiment, the first support member 11 is guided and limited by the arc-shaped limiting groove 30 and the arc-shaped groove 23. Those skilled in the art can set the position, curvature and other parameters of the limiting groove 30 and the arc-shaped groove 23 according to actual needs. Therefore, the relative positional relationship and curvature of the limiting groove 30 and the arc-shaped groove 23 are not described in this embodiment. Specifically, the leveling component 10 can be flipped when the sliding block 14 moves along the arc-shaped groove 23.

[0068] In another implementation, please refer to Figures 1 to 3 The sliding block 14 has a wheel structure and abuts against the inner wall of the arc-shaped groove 23; the sliding block 14 is fixedly connected to the support member 11. When the driving member 21 is activated, causing the sliding block 14 to move along the arc-shaped groove 23, the sliding block 14 will simultaneously rotate due to friction from the groove wall of the arc-shaped groove 23, thereby causing the support member 11 to flip, causing the leveling assembly 10 to flip as a whole. In this embodiment, the support structure does not need to be provided with a guide structure such as the limiting groove 30; it only needs to provide support for the angle-adjustable cell leveling mechanism.

[0069] The inner wall of the arc groove 23 and the outer surface of the sliding block 14 can be provided with friction textures or other structures to increase the friction between them, so that the sliding block 13 can rotate during the movement along the arc groove 23.

[0070] In other embodiments, the two embodiments described above can be combined, that is, while setting the limiting groove 30 on the support structure, the sliding block 14 is configured as a wheel structure that abuts against the inner wall of the arc groove 23.

[0071] In practical applications, the flipping component 20 is used to drive the leveling component 10 to flip and adjust its angle, and is not used as a driving component to drive the leveling component 10 to perform leveling actions. Therefore, the above-described embodiments can meet the angle adjustment requirements in actual production.

[0072] In the above embodiments, when the staff needs to adjust the angle of the contact block 12, they only need to start the drive component 21. Instead of adjusting the angle of each contact block 12 individually, the staff can effectively simplify the adjustment work and improve the angle adjustment efficiency.

[0073] In one embodiment, the drive component 21 is a lead screw motor, which can precisely adjust the relative sliding stroke of the support component 11 and the first guide block 22, thereby precisely adjusting the flip angle of the leveling component 10.

[0074] In a further improved embodiment, a connecting block 13 is provided on the support member 11; a sliding block 14 is provided on one side of the connecting block 13; a transmission block 16 is provided on the other side of the connecting block 13; the flipping assembly 20 includes: a second guide block 24; a transmission groove 25 is provided on the second guide block 24; the output end of the driving member 21 is connected to the second guide block 24 for driving the second guide block 24 to move linearly along the first direction x; the sliding block 14 is slidably disposed in the arc-shaped groove 23; the transmission block 16 is slidably disposed in the transmission groove 25; when the second guide block 24 moves linearly, the connecting block 13 pushes the sliding block 14 to move along the arc-shaped groove 23.

[0075] In this embodiment, when the driving component 21 is activated, it drives the second guide block 24 to move along the first direction x. The second guide block 24 pushes the connecting block 13 to move along the first direction, causing the sliding block 14 on the connecting block 13 to slide along the arc groove 23, thereby causing the support component 11 to flip. During the sliding of the sliding block 13 along the arc groove 23, the transmission block 16 moves along the transmission groove 25 to limit and guide, so that both sides of the connecting block 13 are limited and flip more smoothly.

[0076] Specifically, the transmission groove 25 is arranged along the second direction y, that is, the length direction of the transmission groove 25 is the y-axis direction. The second direction y is perpendicular to the first direction x.

[0077] In a more specific embodiment, the flipping assembly 20 includes a base plate 26; a first guide block 22 is fixed on the base plate 26; and a second guide block 24 is slidably disposed on the base plate 26 along a first direction x.

[0078] The base plate 26 serves to support the first guide block 22 and the second guide block 24. In this embodiment, a guide rail may be provided on the base plate 26; the second guide block 24 is slidably mounted on the guide rail via a sliding plate; the driving member 21 is engaged with the sliding plate. When the driving member 21 starts and drives the lead screw to rotate, the sliding plate drives the second guide block 24 to slide along the guide rail.

[0079] In application, the bottom of the support member 11 can be provided with multiple connecting blocks 13; correspondingly, multiple first guide blocks 22 and second guide blocks 24 are provided. For example, the bottom of the support member 11 can be provided with two connecting blocks 13; the two connecting blocks 13 are symmetrically arranged on both sides of the drive member 21.

[0080] In another embodiment, the flipping assembly 20 includes: a third guide block 27; a third sliding block 17 is provided on the support member 11; the third guide block 27 is fixed to the base plate 26, and a second arc-shaped groove 28 is provided on the third guide block 27; the third guide block 27 is fixed on the base plate 26; and the third sliding block 17 is movably disposed in the second arc-shaped groove 28.

[0081] The cooperation between the third guide block 27 and the third sliding block 17 can further improve the stability of the leveling component 10 during rotation. The first guide block 22, the second guide block 24 and the third guide block 27 can be arranged in parallel intervals on the base plate 26 to increase the support area of ​​the rotation component 20.

[0082] Based on the above embodiments, a second connecting block 18 may be provided on the support member 11; a third sliding block 17 is provided on the second connecting block 18; a locking pin 19 that can adjust the tightness is provided on the second connecting block 18; the locking pin 19 extends into the second arc-shaped groove 28; when the locking pin 19 is locked, it can restrict the relative movement between the second connecting block 18 and the third guide block 27.

[0083] The locking pin 19 can be tightened when it is necessary to fix the support member 11 so that it cannot be rotated. Furthermore, multiple contact blocks 12 can be locked with one locking pin 19. When it is necessary to adjust the angle of multiple contact blocks 12, simply loosen the corresponding locking pin 19.

[0084] In one embodiment, the plurality of contact blocks 12 include a plurality of cold heat-contact elements and a plurality of hot heat-contact elements.

[0085] Specifically, the inventors discovered that during edge leveling of electrodes and diaphragms, the heated contact element can generate heat to soften the material edges, thereby improving the edge shape, but it cannot eliminate the internal stress of the material. Therefore, this embodiment also includes a cooled contact element capable of cooling the material edges, improving the leveling effect through the synergistic effect of heat and cold.

[0086] In applications, the cold heat exchange contact is positioned downstream of the hot heat exchange contact.

[0087] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
