When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] Please refer to Figures 1 to 4 The cell flower basket of the present invention is suitable for supporting a cell 1. A masking adhesive is applied to the edge of the cell 1. The cell 1 includes an exposed portion and a covering portion located at the edge of the exposed portion. The covering portion is masked by the masking adhesive, while the exposed portion is exposed to the masking adhesive. Applying masking adhesive to cells is conventional technology and will not be described in detail here.

[0029] Please refer to Figures 1 to 10 The battery cell flower basket of the embodiment of the present invention includes two support members 2, which are respectively a first support member 2a and a second support member 2b. The first support member 2a and the second support member 2b are arranged at intervals along a first direction. Each support member 2 includes a support plate 201 and a plurality of flower basket teeth 202 fixed to the support plate 201. The flower basket teeth 202 are arranged at intervals along a second direction perpendicular to the first direction. Moreover, the flower basket teeth 202 of the first support member 2a and the flower basket teeth 202 of the second support member 2b are arranged one by one in the first direction to support the corresponding battery cells 1 along the second direction. Each flower basket tooth 202 has a support surface 20211 for supporting the exposed portion, and the support surface 20211 is a curved surface.

[0030] The battery cell flower basket of the embodiment of the present invention can carry multiple battery cells 1, is easy to use, and improves production efficiency. Each flower basket tooth 202 has a support surface 20211 for supporting the exposed part, that is, the contact between the flower basket tooth 202 and the battery cell 1 is on the exposed part, and the mask glue on the battery cell 1 is suspended in the air, and the mask glue does not contact the support member 2, which can avoid friction or adhesion between the support member 2 and the mask glue on the battery cell 1, thereby avoiding the breakage of the mask glue and improving the product yield. Moreover, the support surface 20211 is a curved surface, which can further protect the battery cell 1 and avoid the support member 2 scratching the battery cell 1, further improving the product yield.

[0031] As an example, the first support member 2a and the second support member 2b have the same structure, and the first support member 2a and the second support member 2b are axially symmetrically arranged about the first axis extending along the second direction, which has a simple structure and is more convenient for production and manufacturing.

[0032] In some embodiments, the cell basket can be used to transport the cells 1. In other embodiments, the cell basket can be used in the drying process. It is understood that in other embodiments, the cell basket can also be used in other processes, which will not be described in detail here.

[0033] In some embodiments, the support member 2 is an integrally formed structure, which not only provides a more stable structure but also reduces the difficulty of assembling the battery cell basket and improves assembly efficiency. For example, the support member 2 is an injection molded part, and during the injection molding process, the basket teeth 202 and the support plate 201 are integrally formed.

[0034] As an optional embodiment, the supporting surface 20211 is a spherical surface, which can further protect the battery cell 1 and prevent the supporting member 2 from scratching the battery cell 1, thereby further improving the product yield.

[0035] As an optional embodiment, the support surface 20211 is a cylindrical surface, and the center line of the cylindrical surface extends along a third direction, which is perpendicular to the first direction and the second direction. This can further protect the battery cell 1 and prevent the support member 2 from scratching the battery cell 1, further improving the product yield.

[0036] In some preferred embodiments, please refer to Figure 4 、 Figure 6 、 Figure 8 and Figure 10 The basket tooth body 202 includes a connecting portion 2022 and a limiting end portion 2021. The connecting portion 2022 is fixed to the support plate body 201 and extends perpendicular to the surface of the support plate body 201. The limiting end portion 2021 extends from the end of the connecting portion 2022. The surface of the limiting end portion 2021 includes a supporting surface 20211.

[0037] For some examples, see Figure 4 The support surface 20211 is spherical, that is, the surface of the limiting end 2021 is spherical, and the limiting end 2021 is in point contact with the battery cell 1. The spherical surface of the limiting end 2021, which is used to directly contact the exposed part of the battery cell 1, can better protect the battery cell 1 and fully avoid scratching the battery cell 1.

[0038] Accordingly, in some examples, the connecting portion 2022 is rod-shaped, which can be securely and effectively connected to the limiting end portion 2021. As an example, the connecting portion 2022 can be a round rod structure with a circular cross-section, or a square rod structure with a square cross-section, or other structures, which are not described in detail here.

[0039] For some examples, see Figure 6 、 Figure 8 and Figure 10 The support surface 20211 is a cylindrical surface, that is, the side surface of the limiting end 2021 is configured as the support surface 20211, and the limiting end 2021 is in line contact with the battery cell 1. The portion of the surface of the limiting end 2021 that directly contacts the exposed portion of the battery cell 1 is a cylindrical surface, which not only prevents scratches on the battery cell 1, but also provides better support for the battery cell 1.

[0040] In some preferred embodiments, please refer to Figure 2 and Figure 6 Each support member 2 includes at least two support plates 201 spaced apart along the third direction. Each support plate 201 is strip-shaped and is provided with a plurality of turnbuckle teeth 202 spaced apart along the second direction. The spaced apart support plates 201 along the third direction effectively reduces the weight of the cell turnbuckle and lowers the manufacturing cost.

[0041] For some examples, see Figure 1 and Figure 5 Each support member 2 includes two strip-shaped support plates 201 with the same structure. The two support plates 201 are spaced apart along the third direction, which can not only further reduce the weight of the battery cell flower basket, but also effectively support the battery cell 1. The structure is simple and easy to use.

[0042] In some preferred embodiments, please refer to Figure 7 and Figure 9 Each support member 2 includes a support plate 201 in a rectangular shape, arranged perpendicular to the first direction. In this embodiment, the rectangular shape of the support plate 201 maximizes the strength of the support plate 201, making the structure more reliable. Furthermore, all of the turnbuckles 202 can be fixed to the same support plate 201, making the relative positions of the turnbuckles 202 more stable and the structure more reliable.

[0043] As an optional implementation, please refer to Figure 10 In the third direction, the basket tooth body 202 is an integrated structure. Specifically, each basket tooth body 202 extends from one end of the support plate body 201 to the other end of the support plate body 201 along the third direction. Not only is the structure simpler, but it can also effectively improve the strength of the basket tooth body 202, so that the basket tooth body 202 can more fully and effectively support the battery cell 1, and the structure is more stable.

[0044] As an optional implementation, please refer to Figure 8 In the third direction, the turnbuckle 202 has a split structure. Specifically, each turnbuckle 202 includes at least two tooth segments 202a spaced apart along the third direction. This division of the turnbuckle 202 into multiple segments 202a effectively reduces the weight of the cell turnbuckle and lowers its manufacturing cost.

[0045] In some examples, each basket tooth 202 includes two tooth segments 202a spaced apart along a third direction, and the two tooth segments 202a of the basket tooth 202 of the first support member 2a and the two tooth segments 202a of the basket tooth 202 of the corresponding second support member 2b cooperate to support the corresponding battery cell 1.

[0046] Understandably, please refer to Figure 8 Each tooth body segment 202a includes a connecting portion 2022 and a limiting end portion 2021.

[0047] In some preferred embodiments, please refer to Figure 1 、 Figure 3 、 Figure 5 、 Figure 7 and Figure 9 The cell basket further includes a first end plate 3 and a second end plate 4, which are spaced apart along the second direction. Two support members 2 are fixed between the first end plate 3 and the second end plate 4. In this embodiment, the first end plate 3 and the second end plate 4 cooperate to fix the relative arrangement of the first support member 2a and the second support member 2b, making the overall structure more reliable, thereby more safely and effectively supporting the cell 1.

[0048] In some preferred embodiments, please refer to Figure 1 、 Figure 3 、 Figure 5 、 Figure 7 and Figure 9 The cell flower basket also includes a first reinforcement 5 and a second reinforcement 6. The first reinforcement 5 and the second reinforcement 6 extend along the second direction respectively and extend in parallel. The first reinforcement 5 is fixed between the first end plate 3 and the second end plate 4, and the first reinforcement 5 is fixed to the side of the first support member 2a facing away from the second support member 2b. The second reinforcement 6 is fixed between the first end plate 3 and the second end plate 4, and the second reinforcement 6 is fixed to the side of the second support member 2b facing away from the first support member 2a. In this embodiment, the first reinforcement 5 can effectively increase the strength of the first support member 2a, and the second reinforcement 6 can effectively increase the strength of the second support member 2b, thereby improving the stability of the overall structure and better supporting the cell 1.

[0049] As an example, please refer to Figure 5 and Figure 7 One end of the first reinforcement 5 is fixed to the first end plate 3, and the other end of the first reinforcement 5 is fixed to the second end plate 4. The support plate body 201 of the first support member 2a is fixed to the first reinforcement 5, which is more convenient for installation and disassembly, and the first reinforcement 5 can better support the first support member 2a.

[0050] Correspondingly, one end of the second reinforcement 6 is fixed to the first end plate 3, and the other end of the second reinforcement 6 is fixed to the second end plate 4. The support plate body 201 of the second support member 2b is fixed to the second reinforcement 6, which is more convenient for installation and disassembly, and the second reinforcement 6 can better support the second support member 2b.

[0051] In some examples, the first support member 2a and the first reinforcement member 5 are fixed together by screws, the second support member 2b and the second reinforcement member 6 are fixed together by screws, the first reinforcement member 5 is fixed together with the first end plate member 3 and the second end plate member 4 by screws, and the second reinforcement member 6 is fixed together with the first end plate member 3 and the second end plate member 4 by screws. This structure is simple and easy to use. It should be noted that in other embodiments, other methods can be used to connect and fix the above components, which will not be detailed here.

[0052] In some preferred embodiments, please refer to Figure 1 、 Figure 3 and Figure 5 The cell flower basket further includes a limiting member 7, which extends along the second direction and is fixed between the first end plate 3 and the second end plate 4. The limiting member 7 can be used to limit the cell 1 along the third direction.

[0053] In some examples, the stopper 7 is fixed to the first end plate 3 and the second end plate 4 by screws, which is simple in structure and easy to use. It should be noted that in other embodiments, the stopper 7 can be connected and fixed to the first end plate 3 and the second end plate 4 in other ways, which are not described here.

[0054] As an example, in some usage scenarios, the first direction is the left-right direction, the second direction is the up-down direction, and the third direction is the front-back direction. The first support member 2a and the second support member 2b cooperate with each other to support the battery cell 1 in the up-down direction to prevent the battery cell 1 from falling. In this case, the battery cell basket may include a limiter 7, which can limit the position of the battery cell 1 in the front-back direction, thereby better protecting the battery cell 1. It should be noted that in some embodiments, the battery cell basket may not include the limiter 7. In other words, the battery cell basket only supports the battery cell 1 in the up-down direction. This can be set according to actual circumstances and is not described in detail here.

[0055] As an example, in some usage scenarios, the first direction is the left and right direction, the second direction is the front and back direction, and the third direction is the up and down direction. The first support member 2a and the second support member 2b cooperate with each other to support the battery cell 1 in the front and back directions. That is, the battery cell 1 can lean on the basket tooth body 202 on any side of the front and back sides, and the limiting member 7 can support the battery cell 1 in the up and down directions, thereby limiting the battery cell 1 on the battery cell basket.

[0056] It should be noted that, in other implementations, the first direction, the second direction and the third direction may also be other directions, which are not described in detail here.

[0057] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above embodiments merely represent preferred implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
