Description

Technical Field

[0001] The present application relates to the technical field of battery packaging, and in particular to a battery cell shaping tool. Background Art

[0002] During the top and side sealing process of the battery, due to the influence of the packaging mold or packaging process, the ends of the side seal area of ​​the battery cell may appear outward-shaped, which will affect the sealing and conductivity of the battery cell and cause the battery performance to deteriorate. Therefore, the battery cell needs to be reshaped after the initial packaging.

[0003] In the related art, pressure is applied to the parts of the battery cell that may be deformed through a pressing member. However, the aluminum-plastic film used to encapsulate the battery cell is a very light film. When the battery cell is shaped near the tab end, the tab and the aluminum-plastic film around the tab will cause wrinkles or arc waves, affecting the stability of the tab, thereby creating a risk of battery cell ignition and affecting battery performance.

[0041] Figure 1 The figure shows a schematic diagram of the structure of the battery cell shaping tool provided in one embodiment of the present application. Figure 1 One embodiment of the present application provides a battery cell shaping tool, comprising a driving component 1; a holding component 2, connected to the driving component 1, for crimping or separating with the top sealing area of ​​the battery cell 4 under the drive of the driving component 1; and a shaping component 3, connected to the driving component 1, for performing side shaping on the battery cell 4 under the drive of the driving component 1. The top sealing area of ​​the battery cell 4 is the packaging area on the side where the tab is located. The packaging area is where the two layers of aluminum-plastic film on the upper and lower sides of the battery cell 4 and the tab are bonded together, which can isolate the battery cell 4 from the outside, prevent oxygen, moisture and other components in the external environment from affecting the quality of the battery cell 4, and provide a certain mechanical strength for the battery cell 4 to prevent damage to the battery cell 4 caused by external physical collision, extrusion or deformation.

[0042] Figure 2 FIG2 shows a schematic structural diagram of a pressing assembly 2 provided in an embodiment of the present application. Figure 2 The pressing assembly 2 provided in one embodiment of the present application includes: a lower pressing member 22 and an upper pressing member 21. The lower pressing member 22 and the upper pressing member 21 are correspondingly arranged on both sides of the top sealing area in the first direction. The lower pressing member 22 is used to cooperate with the upper pressing member 21 to press or separate from the top sealing area. Among them, the upper pressing member 21 is arranged on the upper side of the top sealing area, and the lower pressing member 22 is arranged on the lower side of the top sealing area. The first direction is as follows Figure 2 The direction indicated by mark A.

[0043] In one possible embodiment, the top sealing area of ​​the battery cell 4 is flush with the upper surface of the lower pressing member 22, and the process of the lower pressing member 22 cooperating with the upper pressing member 21 can be: using the driving component 1 to drive the upper pressing member 21 to move toward the lower pressing member 22 along the first direction until it and the lower pressing member 22 jointly press the top sealing area; after the battery cell 4 is laterally reshaped, using the driving component 1 to drive the upper pressing member 21 to move away from the lower pressing member 22 along the first direction to separate from the battery cell 4. Optionally, the top sealing area of ​​the battery cell 4 is placed between the lower pressing member 22 and the upper pressing member 21, and using the driving component 1 to drive the upper pressing member 21 and the lower pressing member 22 to move toward each other along the first direction until they jointly press the top sealing area; after the battery cell 4 is laterally reshaped, using the driving component 1 to drive the upper pressing member 21 and the lower pressing member 22 to move away from each other along the first direction to separate from the battery cell 4.

[0044] In one possible implementation, see Figure 2 The upper holding member 21 includes an upper positioning plate 211 for contacting the top sealing area; an upper connecting plate 212, a first end of which is connected to the upper positioning plate 211, and a second end of which is connected to the driving assembly 1. The lower holding member 22 includes a lower positioning plate 221 for contacting the top sealing area; and a lower connecting plate 222, a first end of which is connected to the lower positioning plate 221.

[0045] Among them, the structure of the upper holding member 21 is consistent with that of the lower holding member 22, and the upper holding member 21 is taken as an example for explanation. The upper positioning plate 211 includes a positioning bar and a positioning block. The positioning bar and the positioning block are arranged in a "T" shape. The extension direction of the positioning bar is the width direction of the battery cell 4, that is, the extension direction of the side where the tab of the battery cell 4 is located. The length of the positioning bar in the extension direction is less than or equal to the width of the battery cell 4. The length of the positioning block close to the positioning bar is less than the length of the positioning bar, and is greater than or equal to the length of the tab of the battery cell 4 in this direction. The first end of the upper connecting plate 212 is connected to the side of the positioning block of the upper positioning plate 211 facing away from the battery cell 4.

[0046] Optionally, before side shaping the battery cell 4, the tabs of the battery cell 4 are placed on the positioning blocks of the lower pressing member 22, and the top sealing area of ​​the battery cell 4 is placed on the positioning strips of the lower pressing member 22, when the top sealing area of ​​the battery cell 4 is flush with the upper surface of the lower pressing member 22. In this way, the positioning strips and the positioning blocks are used to locate the placement of the battery cell 4 to avoid placement deviation or tilt, thereby improving the accuracy of the shaping.

[0047] The above-mentioned battery cell shaping tooling includes: a driving component 1; a holding component 2, connected to the driving component 1, for crimping or separating with the top sealing area of ​​the battery cell 4 under the drive of the driving component 1; a shaping component 3, connected to the driving component 1, for performing side shaping on the battery cell 4 under the drive of the driving component 1. In this embodiment, before the side shaping of the battery cell 4 is performed, the holding component 2 is used to press the top sealing area of ​​the battery cell 4. When the holding component 2 is crimped with the top sealing area, the holding component 2 can fully cover the tab and cover the area around the tab in the top sealing area, thereby ensuring the flatness of the tab and the surrounding area during the side shaping of the battery cell 4, preventing the tab and the aluminum-plastic film around the tab from warping or wrinkling, and improving the yield of the battery cell 4.

[0048] Figure 3 FIG. 1 shows a schematic structural diagram of the shaping component 3 in an embodiment of the present application. Figure 3 The shaping assembly 3 in the cell shaping tool provided in one embodiment of the present application includes: a first clamping member 31 and a second clamping member 32. The first clamping member 31 and the second clamping member 32 are correspondingly arranged on both sides of the top sealing area in the second direction, and the second direction is perpendicular to the first direction. Figure 3 The first clamping member 31 and the second clamping member 32 have the same structure, as shown in FIG. Figure 3 In the shaping component 3 shown, Figure 3 The clamping member on the left side of the viewing angle is the first clamping member 31 , and the clamping member on the right side is the second clamping member 32 .

[0049] In one possible embodiment, the first clamping member 31 includes: a support seat 311, connected to the drive assembly 1, and configured to move in the second direction under the drive of the drive assembly 1; and a clamping portion 312, connected to the support seat 311, with the support seat 311 and the clamping portion 312 being arranged perpendicularly. Driven by the support seat 311, the clamping portion 312 can move toward or away from the battery cell 4 along the second direction. The surface of the clamping portion 312 facing the battery cell 4 is flat. Thus, the support seat 311 and the clamping portion 312 in the shaping assembly 3 cooperate to uniformly apply force in the second direction to the side of the battery cell 4, thereby shaping the battery cell 4.

[0050] In one possible embodiment, the surface of the clamping portion 312 on the side close to the battery cell 4 is provided with an elastic material. It is understandable that the surface of the upper positioning plate 211 and the lower positioning plate 221 in the holding assembly 2 on the side close to the battery cell 4 is also provided with an elastic material. Optionally, the elastic material may include rubber, silicone or polyurethane foam, and the elastic material may be bonded to the surface of the clamping portion 312, the upper positioning plate 211 and the lower positioning plate 221 by an adhesive, or may be embedded in a groove on the surface. In this embodiment, by providing an elastic material on the surface of the clamping portion 312, the upper positioning plate 211 and the lower positioning plate 221 on the side that contacts the battery cell 4, a buffering effect is played during the side shaping of the battery cell 4, so that the battery cell 4 is subjected to more uniform force, avoiding excessive local force on the battery cell 4, resulting in structural deformation, indentation or damage, and providing the elastic material can increase the friction between the battery cell 4, avoid sliding or offsetting the battery cell 4 during the shaping process, and ensure the accuracy of the shaping.

[0051] Optionally, a waist-shaped hole is provided on the support base 311, and the clamping portion 312 is adjustably connected to the support base 311 through the waist-shaped hole to expand the movable space of the clamping portion 312 in the second direction, thereby adapting to battery cells 4 of different sizes.

[0052] Optionally, the shaping assembly 3 further includes a driving support plate, one side of which is connected to the support seat 311 and the other side of which is connected to the driving assembly 1. A receiving groove is provided on one side of the driving support plate near the support seat 311 for receiving the support seat 311, so that the support seat 311 can be stably connected to the driving assembly 1, thereby accurately driving the clamping member to move in the second direction, thereby avoiding affecting the side shaping effect of the battery cell 4.

[0053] Continue reading Figure 1 and Figure 3 The drive assembly 1 in the battery cell shaping tool provided in one embodiment of the present application includes: a first drive member 11 connected to the pressing assembly 2 for driving the pressing assembly 2; and a second drive member 12 connected to the shaping assembly 3 for driving the shaping assembly 3.

Optionally, the first driving member 11 is connected to the upper connecting plate 212 in the upper pressing member 21, and is connected to the lower connecting plate 222 in the lower pressing member 22, so as to respectively drive one or both of the upper pressing member 21 and the lower pressing member 22 to move relative to the battery cell 4 along the first direction, thereby achieving crimping or separation with the battery cell 4.

[0055] In one possible embodiment, the second driving member 12 can be a parallel finger cylinder, which is connected to the support base 311 and is used to drive the support base 311 to move along the second direction. Specifically, the first end of the second driving member 12 is connected to the support base 311 of the first clamping member 31 in the shaping assembly 3, and the second end of the second driving member 12 is connected to the support base 311 of the second clamping member 32 in the shaping assembly 3, so as to drive the first clamping member 31 and the second clamping member 32 to move toward each other along the second direction to shape the battery cell 4, or to move away from each other along the second direction to separate from the battery cell 4. By using a parallel finger cylinder as the second driving member 12 to drive the shaping assembly 3, the magnitude of the force acting on the side shaping of the battery cell 4 can be controlled by adjusting the pressure of the gas source, thereby improving the shaping accuracy and avoiding damage to the battery cell 4 or incomplete shaping.

Similarly, the first driving member 11 can also apply driving force to the lower mounting plate 62, driving the lower mounting plate 62 to drive the lower connecting plate 222 and the lower positioning plate 221 to move along the first direction until they cooperate with the upper positioning plate 211 and the upper connecting plate 212, pressing the battery cell 4 or separating from the battery cell 4.
