[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0039] This application proposes a battery sealing mold. Figures 1 to 5 As shown in the accompanying drawings, the Y direction is the first direction, the X direction is the second direction, and the first direction and the second direction intersect each other.

[0040] See also Figures 1 to 3 In some embodiments of the present application, the battery sealing mold includes a clamping member 1, and a first accommodating cavity 2 extending along a first direction Y is provided on the clamping member 1, and the first accommodating cavity 2 is configured to accommodate the neck portion 172 of the battery 17; wherein, the cavity wall of the first accommodating cavity 2 contacts the neck portion 172 of the battery 17, thereby preventing the neck portion 172 of the battery 17 from being deformed when the battery sealing mold performs a sealing operation on the battery 17.

[0041] The first direction Y is the height direction of the battery 17 .

[0042] In some embodiments of the present application, the battery sealing mold includes a packaging member 3, the packaging member 3 includes a packaging portion 31, the packaging portion 31 is located on one side of the clamping member 1 in the first direction Y, and at least a portion of the packaging portion 31 is located in the first accommodating cavity 2 to abut the sealing portion 171 of the battery 17; that is, in this embodiment, the packaging portion 31 extends into the first accommodating cavity 2 to perform a sealing operation on the sealing portion 171 of the battery 17 to seal the battery 17.

[0043] It should be supplemented that the battery 17 includes a main body 173 , a neck portion 172 and a sealing portion 171 sequentially connected in the first direction Y, and the battery 17 has a rolling groove 18 arranged between the neck portion 172 and the sealing portion 171 .

[0044] The first sealing operation of the battery 17 is to press the sealing portion 171 of the battery 17 extending along the first direction Y to form the sealing portion 171 of the battery 17 as shown in the present application. Figure 3The structure of the battery 17, at this time the sealing portion 171 of the battery 17 is inclined; the second sealing operation of the battery 17 is for this application Figure 3 The sealing portion 171 of the battery 17 is pressed so that the sealing portion 171 of the battery 17 is deformed and flattened to the horizontal plane in the second direction X; the third sealing operation of the battery 17 is to further compact the sealing portion 171 of the battery 17 on the basis of the second sealing operation to ensure the sealing of the sealing portion 171 of the battery 17 and adjust the height of the battery 17 in the first direction Y.

[0045] In the technical solution of the present application, by placing the neck portion 172 of the battery 17 in the first accommodating cavity 2, when the packaging portion 31 performs a second sealing operation on the sealing portion 171 of the battery 17, at least a portion of the packaging portion 31 is located in the first accommodating cavity 2 to abut against the sealing portion 171 of the battery 17 and deform. At this time, the neck portion 172 of the battery 17 is not easy to deform due to the limitation of the cavity size of the first accommodating cavity 2, thereby avoiding burrs on the neck portion 172 of the battery 17 due to deformation, thereby improving the product yield of the battery 17.

[0046] It can be understood that at least part of the packaging portion 31 is located in the first accommodating cavity 2, and the sealing portion 171 of the battery 17 is located between the packaging portion 31 and the neck portion 172 of the battery 17. Accordingly, the neck portion 172 of the battery 17 will not protrude outside the first accommodating cavity 2 during the second sealing operation, thereby reducing the risk of burrs on the neck portion 172 of the battery 17 during the second sealing operation.

[0047] Similarly, since the packaging part 31 can extend into the first accommodating cavity 2 during the second sealing operation, the packaging part 31 can adjust the size of entering into the first accommodating cavity 2 according to actual needs, thereby making the battery sealing mold of the present application applicable to the sealing operations of batteries 17 of different sizes.

[0048] In addition, when the battery 17 is sealed, the battery 17 needs to be limited. In one embodiment of the present application, the clamping member 1 can limit the neck portion 172 of the battery 17 while also limiting the main body 173 of the battery 17 to prevent the battery 17 from moving during pressing; in some embodiments of the present application, the neck portion 172 of the battery 17 is limited by the clamping member 1, and other tooling structures of the battery 17 sealing device can also be used to limit the main body 173 of the battery 17 to prevent the battery 17 from moving during pressing.

[0049] In addition, when the battery 17 is sealed, the packaging member 3 and the clamping member 1 will move relative to each other in the first direction Y; therefore, in one embodiment of the present application, the packaging member 3 remains stationary, and the clamping member 1 and the battery 17 move along the first direction Y; in another embodiment of the present application, the clamping member 1 and the battery 17 remain stationary, and the packaging member 3 moves along the first direction Y; in yet another embodiment of the present application, the packaging member 3, the clamping member 1 and the battery 17 are all able to move along the first direction Y.

[0050] In some embodiments of the present application, in order to ensure the stability of the battery 17 during the second packaging process, the clamping member 1 and the battery 17 remain stationary, and the packaging member 3 moves along the first direction Y so that the packaging portion 31 can move into the first accommodating cavity 2 to press the sealing portion 171 of the battery.

[0051] See also Figure 1 In some embodiments of the present application, the portion of the packaging portion 31 located in the first accommodating chamber 2 contacts the cavity wall of the first accommodating chamber 2; that is, in this embodiment, since the packaging portion 31 extends into the first accommodating chamber 2, the portion of the packaging portion 31 located in the first accommodating chamber 2 contacts the cavity wall of the first accommodating chamber 2, thereby preventing the neck portion 172 of the battery 17 from deforming at the gap between the cavity wall of the first accommodating chamber 2 and the outer peripheral surface of the packaging portion 31 during the second sealing operation, thereby preventing burrs from occurring.

[0052] In some embodiments of the present application, the size of the first accommodating cavity 2 in the first direction Y is larger than the size of the packaging portion 31 in the first direction Y; that is, in this embodiment, the size of the first accommodating cavity 2 is sufficient to accommodate the neck portion 172 of the battery 17 and the packaging portion 31, so as to ensure that the packaging portion 31 can enter the first accommodating cavity 2 to perform a secondary sealing operation on the battery 17, thereby reducing the risk of burrs appearing on the neck portion 172 of the battery 17 during the second sealing operation.

[0053] See also Figure 4In some embodiments of the present application, the size of the first accommodating cavity 2 in the first direction Y is L1; wherein L1 satisfies: 2.9 mm ≤ L1 ≤ 3.1 mm; such a configuration allows the first accommodating cavity 2 to accommodate the neck portion 172 of the battery 17, so that the neck portion 172 of the battery 17 is not easily deformed and produces burrs when the battery 17 undergoes a second sealing operation. If the value of L1 is less than 2.9 mm, the size of the first accommodating cavity 2 in the first direction Y is insufficient to completely accommodate the neck portion 172 of the battery 17, thereby causing the neck portion 172 of the battery 17 to easily deform and produce burrs when the battery 17 undergoes a second sealing operation. If the value of L1 is greater than 3.1 mm, the size of the first accommodating cavity 2 in the first direction Y is too large. During the second sealing operation, the packaging portion 31 may not have compacted the sealing portion 171 of the battery 17 yet, and the packaging component 3 may collide with the clamping component 1 in the first direction Y, thereby causing damage to the packaging component 3 and the clamping component 1.

[0054] The value of L1 can be 2.9mm, 2.91mm, 2.92mm, 2.93mm, 2.94mm, 2.95mm, 2.96mm, 2.97mm, 2.98mm, 2.99mm, 3.00mm, 3.01mm, 3.02mm, 3.03mm, 3.04mm, 3.05mm, 3.06mm, 3.07mm, 3.08mm, 3.09mm, or 3.1mm. The value of L1 is not limited to the values ​​listed above, and other values ​​not listed within this range are also applicable.

[0055] See also Figure 5 In some embodiments of the present application, the dimension of the packaging portion 31 in the first direction Y is L2; ​​wherein L2 satisfies: 1.95mm≤L2≤2.05mm; such a configuration enables the packaging portion 31 to perform a second sealing operation on the battery 17 in the first accommodating cavity 2 whose dimension in the first direction Y is between 2.9mm and 3.1mm. If the value of L2 is less than 1.95mm, when the packaging portion 31 presses the sealing portion 171 of the battery 17, the packaging part 3 may abut against the clamping part 1 in the first direction Y before the packaging portion 31 presses the sealing portion 171 of the battery 17, thereby causing damage to the packaging part 3 and the clamping part 1; if the value of L2 is greater than 2.05mm, the manufacturing cost of the packaging portion 31 will increase.

[0056] The value of L2 can be 1.95 mm, 1.96 mm, 1.97 mm, 1.98 mm, 1.99 mm, 2.00 mm, 2.01 mm, 2.02 mm, 2.03 mm, 2.04 mm, or 2.05 mm. The value of L2 is not limited to the values ​​listed above, and other values ​​not listed within the range are also applicable.

[0057] In some embodiments of the present application, a second accommodating cavity 4 extending along the first direction Y is further provided on the clamping member 1, and the second accommodating cavity 4 is provided on the side of the first accommodating cavity 2 away from the packaging member 3 in the first direction Y and is connected to the first accommodating cavity 2; wherein, the second accommodating cavity 4 is configured to limit the main body 173 of the battery 17; in this embodiment, the clamping member 1 limits the main body 173 of the battery 17 through the first accommodating cavity 2 to achieve the fixation of the battery 17 by the clamping member 1, so that the clamping member 1 can simultaneously limit and fix the neck portion 172 and the main body 173 of the battery 17 to ensure the reliability of the fixation of the battery 17 on the clamping member 1.

[0058] In some embodiments of the present application, the battery sealing mold further includes at least one protrusion 5, which is disposed on the wall of the first accommodating cavity 2; wherein the protrusion 5 is configured to extend into the rolling groove 18 of the battery 17. By providing the protrusion 5 to extend into the rolling groove 18 of the battery 17, deformation of the portion of the battery 17 located in the rolling groove 18 by the sealing portion 31 is prevented during the second sealing operation.

[0059] In some embodiments of the present application, the shape of the protrusion 5 matches the shape of the rolling groove 18 of the battery 17 .

[0060] In some embodiments of the present application, the protrusion 5 and the clamping member 1 are integrally formed.

[0061] In some embodiments of the present application, the clamping member 1 includes at least one clamping portion 11. In one embodiment, the clamping member 1 includes a clamping portion 11, that is, the first accommodating cavity 2 and the second accommodating cavity 4 are formed in the clamping portion 11, and the battery 17 is assembled to the clamping portion 11 to limit and fix the battery 17; in some embodiments of the present application, the clamping member 1 includes two or more clamping portions 11, that is, the first accommodating cavity 2 and the second accommodating cavity 4 are formed by multiple clamping portions 11, and the provision of multiple clamping portions 11 can facilitate the separation between the battery 17 and the package 3.

[0062] See also Figure 6 In some embodiments of the present application, the clamping member 1 includes three clamping portions 11, that is, the first accommodating cavity 2 and the second accommodating cavity 4 are formed by the three clamping portions 11, and the setting of the three clamping portions 11 can facilitate the separation between the battery 17 and the clamping member 1.

[0068] In some embodiments of the present application, the package 3 also includes a main body 32, which is located on the side of the package 31 away from the clamping member 1 in the first direction Y and is connected to the package 31; by providing the main body 32, the main body 32 is connected to the fixing structure of the battery sealing device to achieve the fixation of the package 3 in the battery sealing device.

[0069] In some embodiments of the present application, a card slot 12 is provided on the peripheral side of the main body 32. By providing the card slot 12, the fixing structure in the battery sealing device can cooperate with the card slot 12 to fix the package 3.

[0070] In some embodiments of the present application, a through groove 10 extending along the first direction Y is provided through the main body 32, and the through groove 10 is connected to the avoidance groove 8. By providing the through groove 10, when the battery 17 is unloaded, a pressure rod can be inserted into the through groove 10, and the pressure rod can abut against the battery 17, so that the battery 17 can be quickly separated from the battery sealing mold.

[0071] In some embodiments of the present application, the cross-sectional area of ​​the main body portion 32 in the direction perpendicular to the first direction Y is greater than the cross-sectional area of ​​the packaging portion 31 in the direction perpendicular to the first direction Y; such a configuration enables the main body portion 32 to provide sufficient physical part to connect with the fixed structure of the battery sealing device.
