Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a battery cell coating device. Background Technology
[0002] During battery manufacturing, to ensure insulation between the battery cell's tabs and the casing / cover, adhesive tape is typically applied to the tab end of the cell in the cell's structural design. In related technologies, during the coating process, adhesive tape is usually first applied to the outer periphery of the cell, extending beyond the end of the cell, and then directly pressed onto the tab end face. However, this coating method makes it difficult to control the shape of the adhesive tape. During the pressing process, the adhesive tape extending beyond the cell's end tends to fold outwards, exceeding the tab end face or the cell's outer diameter. It also easily leads to the adhesive tape not completely adhering to the cell's end face, reducing coating yield and consistency, and increasing product scrap rate.
[0003] Therefore, there is an urgent need for a battery cell coating device to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a battery cell coating device to improve coating yield and coating consistency, and reduce product scrap rate.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] A battery cell coating device, comprising:
[0007] A glue-collecting mechanism includes a glue-collecting drive assembly and a glue-collecting assembly. The glue-collecting assembly has a glue-collecting hole, and the hole wall includes a glue-collecting hole wall. The glue-collecting hole wall is inclined from the side of its end face near the battery cell to the side of its end face away from the battery cell toward the center hole of the battery cell. The output end of the glue-collecting drive assembly is connected to the glue-collecting assembly for transmission. The glue-collecting drive assembly can drive the glue-collecting assembly to move toward the end face near the battery cell, so that the hole wall of the glue-collecting hole folds the adhesive paper extending from the end face of the battery cell toward the center hole of the battery cell.
[0008] The adhesive pressing mechanism includes an adhesive pressing drive component and an adhesive pressing component. The output end of the adhesive pressing drive component is connected to the adhesive pressing component. The adhesive pressing drive component can drive the adhesive pressing component to move towards the end face of the battery cell, so that the adhesive pressing component passes through the adhesive receiving hole and presses the folded adhesive paper onto the end face of the battery cell.
[0009] As an optional solution, a plurality of glue-collecting teeth are provided at intervals along the circumference of the glue-collecting hole on the hole wall, and the inner wall of the glue-collecting teeth is inclined towards the center hole of the battery cell from the side of its end face near the battery cell to the side of its end face away from the battery cell.
[0010] As an optional solution, the wall of the glue collection hole further includes a mounting hole wall, which is connected to the side of the glue collection hole wall away from the end face of the battery cell, and a plurality of glue collection teeth are provided on the mounting hole wall at intervals along the circumference of the glue collection hole.
[0011] As an optional embodiment, the inner wall of the collecting tooth extends from the end face of the battery cell to the end face of the collecting hole wall away from the battery cell, and the inclination angle of the inner wall of the collecting tooth is the same as the inclination angle of the collecting hole wall.
[0012] As an optional solution, the inclination angle of the adhesive collection hole wall is 30° to 70°;
[0013] And / or, the inclination angle of the inner wall of the receiving tooth is 30° to 70°.
[0014] As an optional solution, a through-groove is formed between two adjacent glue-collecting teeth. Multiple glue-pressing teeth are arranged at intervals along the circumference of the glue-pressing assembly on the outer peripheral wall of the glue-pressing assembly. The multiple glue-pressing teeth are arranged in a one-to-one correspondence with the multiple through-grooves, and the glue-pressing teeth can pass through the corresponding through-grooves.
[0015] As an optional solution, the end face shape of the adhesive bonding assembly and the end face shape of the plurality of adhesive bonding teeth are matched with the end face shape of the battery cell.
[0016] As an optional solution, the cell coating device further includes:
[0017] Mounting base, wherein the adhesive receiving drive assembly and the adhesive pressing drive assembly are provided on the mounting base;
[0018] A guide rail is disposed on the mounting base, the guide rail extends along the moving direction of the glue collection assembly and the glue pressing assembly, and both the glue collection assembly and the glue pressing assembly move along the guide rail.
[0019] As an optional solution, the glue-collecting mechanism and the glue-pressing mechanism are provided at both ends of the battery cell in the axial direction.
[0020] As an optional solution, the cell coating device further includes:
[0021] A clamping mechanism is provided with a clamping groove, which is used to clamp and fix the battery cell.
[0022] The beneficial effects of this utility model are:
[0023] This invention provides a battery cell coating device. During the coating operation, the device first drives a glue-collecting component to move towards the end face of the battery cell via a glue-collecting drive component. This causes the wall of the glue-collecting hole to fold the adhesive paper extending from the end face of the battery cell towards the center hole of the battery cell, achieving a pre-grafting operation. Then, a glue-pressing drive component drives a glue-pressing component to move towards the end face of the battery cell. This causes the glue-pressing component to pass through the glue-collecting hole and press the folded adhesive paper onto the end face of the battery cell. This not only prevents the adhesive paper extending from the end face of the battery cell from folding outwards during the pressing process, but also effectively ensures that the adhesive paper extending from the end face of the battery cell can be completely adhered to the end face of the battery cell, improving the coating yield and consistency, and reducing the product scrap rate.

[0034] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0035] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0037] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0038] In related technologies, when coating battery cells, adhesive tape is typically applied to the outer periphery of the cell, extending beyond the end of the cell. This extended portion of the tape is then directly pressed onto the tab end face of the cell. However, this coating method makes it difficult to control the shape of the adhesive tape. During the pressing process, the extended portion of the tape tends to fold outwards, exceeding the tab end face or the outer diameter of the cell. It also easily leads to the tape not completely adhering to the cell's end face, reducing coating yield and consistency, and increasing product scrap rate.
[0039] To solve the above problems, such as Figures 1-6 As shown, this embodiment provides a battery cell coating device, which includes a glue-collecting mechanism 1 and a glue-pressing mechanism 2. The glue-collecting mechanism 1 includes a glue-collecting drive assembly 11 and a glue-collecting assembly 12. The glue-collecting assembly 12 has a glue-collecting hole 1211, and the hole wall of the glue-collecting hole 12111 is a glue-collecting hole wall 12111. The glue-collecting hole wall 12111 is inclined from the side near the end face of the battery cell 20 to the side away from the end face of the battery cell 20 toward the center hole of the battery cell 20. The output end of the glue-collecting drive assembly 11 is connected to the glue-collecting assembly 12. The adhesive receiving assembly 11 can drive the adhesive receiving component 12 to move towards the end face of the battery cell 20, so that the wall of the adhesive receiving hole 1211 folds the adhesive paper 30 extending from the end face of the battery cell 20 towards the center hole of the battery cell 20. The adhesive pressing mechanism 2 includes an adhesive pressing drive assembly 21 and an adhesive pressing assembly 22. The output end of the adhesive pressing drive assembly 21 is connected to the adhesive pressing assembly 22. The adhesive pressing drive assembly 21 can drive the adhesive pressing assembly 22 to move towards the end face of the battery cell 20, so that the adhesive pressing assembly 22 passes through the adhesive receiving hole 1211 and presses the folded adhesive paper 30 onto the end face of the battery cell 20. The battery cell coating device provided in this embodiment, when performing the coating operation on the battery cell 20, such as Figure 1 and Figure 4 As shown, the adhesive collection drive assembly 11 first drives the adhesive collection assembly 12 to move towards the end face of the battery cell 20, so that the wall of the adhesive collection hole 1211 folds the adhesive paper 30 extending from the end face of the battery cell 20 towards the center hole of the battery cell 20, thus realizing the pre-collection of adhesive paper 30. Then, as shown... Figure 5 As shown, the pressure-pressing drive assembly 21 drives the pressure-pressing assembly 22 to move towards the end face of the battery cell 20, so that the pressure-pressing assembly 22 passes through the glue collection hole 1211 and presses the folded adhesive paper 30 onto the end face of the battery cell 20. This not only avoids the adhesive paper 30 extending outward from the battery cell 20 during the pressure-pressing process, but also effectively ensures that the adhesive paper 30 extending outward from the battery cell 20 can be completely adhered to the end face of the battery cell 20, thereby improving the coating yield and coating consistency, and reducing the product scrap rate.
[0040] It should be noted that, in this embodiment, as Figure 1 As shown, before the battery cell 20 is coated, the outer periphery of the end of the battery cell 20 is already wrapped with adhesive tape 30, and the adhesive tape 30 extends outward from the end of the battery cell 20. Figure 6 As shown, the cell coating device is only used to press and adhere the adhesive paper 30 extending from the end face of the cell 20 to the end face of the cell 20, and the adhesive paper 30 only covers the edge of the end of the cell 20, and does not cover the entire end of the cell 20.
[0041] Optionally, in this embodiment, the adhesive receiving drive assembly 11 can be a drive cylinder, which has the advantage of reliable operation. Optionally, the adhesive pressing drive assembly 21 can be a drive cylinder, which has the advantage of reliable operation. Optionally, in this embodiment, as... Figure 6 As shown, after the cell coating device completes the coating operation on the cell 20, the pressure drive assembly 21 drives the pressure assembly 22 to move and reset in the direction away from the end face of the cell 20. Then, the glue collection drive assembly 11 drives the glue collection assembly 12 to move and reset in the direction away from the end face of the cell 20, so as to facilitate the corresponding coating operation on the next cell 20.
[0042] Optionally, in this embodiment, as Figure 1 As shown, the battery cell coating device also includes a clamping mechanism 5, which has a clamping groove 51 for clamping and fixing the battery cell 20. Optionally, in this embodiment, the clamping groove 51 clamps and fixes the outer peripheral wall of the battery cell 20, and the outer peripheral side of the battery cell 20 clamped by the clamping groove 51 is already wrapped and fixed with adhesive paper 30, and the adhesive paper 30 extends out of the end of the battery cell 20. Optionally, the clamping mechanism 5 is provided with multiple clamping grooves 51 at intervals, and each clamping groove 51 is used to clamp and fix one battery cell 20. Optionally, in this embodiment, when the conveying device conveys the clamping mechanism 5 holding the battery cell 20 to the glue receiving mechanism 1 and the glue pressing mechanism 2, the battery cell coating device performs a coating operation on the battery cell 20 clamped and fixed by the clamping mechanism 5. After the battery cell coating device completes the coating operation on the battery cell 20, the conveying device conveys the clamping mechanism 5 holding the battery cell 20 to the next station. The above-described design makes the cell coating device ingeniously structured. It can be directly added to existing battery manufacturing equipment and shares process cycle times with other stations on the equipment, effectively improving device uptime, increasing production capacity, and enhancing process yield and product performance. Since the specific structure of the clamping groove 51 for holding and fixing the outer periphery of the cell 20 is prior art, it will not be described in detail here.
[0043] Optionally, in this embodiment, as Figure 2 and Figure 3As shown, multiple adhesive-collecting teeth 1212 are spaced circumferentially along the wall of the adhesive-collecting hole 1211. The inner wall of each adhesive-collecting tooth 1212 slopes towards the center hole of the battery cell 20 from the side closest to the end face of the battery cell 20 to the side furthest from the end face of the battery cell 20. By providing multiple adhesive-collecting teeth 1212, the adhesive paper 30 extending from the end face of the battery cell 20 is folded towards the center hole of the battery cell 20, ensuring the uniformity of folding of the adhesive paper 30 towards the center hole of the battery cell 20 at various circumferential positions, effectively improving the folding effect of the adhesive paper 30.
[0044] Optionally, the number of adhesive receiving teeth 1212 can be optimized and adapted according to the flatness requirements of the adhesive paper 30 after compression and the degree of wrinkling of the adhesive paper 30. In this embodiment, the specific number of adhesive receiving teeth 1212 is not specifically limited.
[0045] Optionally, in this embodiment, as Figure 2 and Figure 3 As shown, the wall of the adhesive collection hole 1211 also includes a mounting hole wall 12112. The mounting hole wall 12112 is connected to the side of the adhesive collection hole wall 12111 away from the end face of the battery cell 20, and a plurality of adhesive collection teeth 1212 are arranged on the mounting hole wall 12112 at intervals along the circumference of the adhesive collection hole 12111. With the above arrangement, when the adhesive pressing assembly 22 is fed toward the end face of the battery cell 20, the adhesive collection hole wall 12111 first contacts the adhesive paper 30 extending out of the end face of the battery cell 20, so that the adhesive paper 30 is folded toward the central hole of the battery cell 20 under the action of the adhesive collection hole wall 12111. During the continuous feeding process of the adhesive pressing assembly 22, the plurality of adhesive collection teeth 1212 then contact the adhesive paper 30, so that the adhesive paper 30 continues to be folded toward the central hole of the battery cell 20 under the action of the inner wall of the plurality of adhesive collection teeth 1212, effectively improving the folding effect of the adhesive paper 30.
[0046] Optionally, in this embodiment, as Figure 2 and Figure 3 As shown, the inner wall of the adhesive-collecting tooth 1212 extends from the end face near the battery cell 20 to the end face away from the battery cell 20 of the adhesive-collecting hole wall 12111, and the inclination angle of the inner wall of the adhesive-collecting tooth 1212 is the same as the inclination angle of the adhesive-collecting hole wall 12111. This arrangement effectively ensures the continuity of the folding of the adhesive paper 30 by the inner walls of the adhesive-collecting hole wall 12111 and the adhesive-collecting tooth 1212, thus guaranteeing the folding effect of the adhesive paper 30.
[0047] Optionally, in this embodiment, the inclination angle of the adhesive collection hole wall 12111 is 30° to 70°. Specifically, the inclination angle of the adhesive collection hole wall 12111 can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, or 70°. Setting these values achieves a slow folding of the adhesive tape 30, ensuring the folding effect of the adhesive tape 30. Optionally, in this embodiment, the inclination angle of the inner wall of the adhesive collection tooth 1212 is 30° to 70°. Specifically, the inclination angle of the inner wall of the adhesive collection tooth 1212 can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, or 70°. Setting these values achieves a slow folding of the adhesive tape 30, ensuring the folding effect of the adhesive tape 30. It should be noted that as long as the inclination angle of the wall of the glue collection hole 12111 is the same as the inclination angle of the inner wall of the glue collection tooth 1212, it is acceptable.
[0048] It should be noted that in this embodiment, the battery cell 20 is a cylindrical battery cell. In other embodiments, the shape of the battery cell 20 is not limited to cylindrical; it can also be elliptical, square, rhomboid, polygonal, or racetrack-shaped, etc., and the size of the battery cell 20 can be adapted according to specific needs. It should also be noted that the adhesive tape 30 can be brown high-temperature insulating tape, or it can be other components that serve an insulating function.
[0049] Optionally, in this embodiment, as Figure 1 and Figure 3 As shown, the glue collection assembly 12 includes a glue collection plate 121 and a connecting plate 122 connected to each other. The glue collection plate 121 has a glue collection hole 1211, and the connecting plate 122 is connected to the output end of the glue pressing drive assembly 21.
[0050] Optionally, in this embodiment, as Figures 1-3 As shown, a through-groove 1213 is formed between two adjacent adhesive-collecting teeth 1212. Multiple adhesive-collecting teeth 2211 are spaced apart along the circumference of the outer peripheral wall of the adhesive-collecting assembly 22. Each adhesive-collecting tooth 2211 corresponds to one of the multiple through-grooves 1213, allowing the adhesive-collecting teeth 2211 to pass through the corresponding through-grooves 1213. This arrangement ensures that the end face of the adhesive-collecting assembly 22 and the end faces of the multiple adhesive-collecting teeth 2211 jointly press the folded adhesive paper 30 against the end face of the battery cell 20, guaranteeing uniformity of pressure on all positions along the circumference of the adhesive paper 30 and effectively ensuring the flatness of the pressed adhesive paper 30.
[0051] Optionally, in this embodiment, as Figures 4-6As shown, the adhesive pressing assembly 22 includes an adhesive pressing column 221 and a mounting plate 222 connected to each other. Multiple adhesive pressing teeth 2211 are spaced circumferentially along the outer peripheral wall of the adhesive pressing column 221. The end faces of the adhesive pressing column 221 and the multiple adhesive pressing teeth 2211 together press the folded adhesive paper 30 against the end face of the battery cell 20. The mounting plate 222 is drive-connected to the output end of the adhesive pressing drive assembly 21. Optionally, the end faces of the adhesive pressing column 221 and the multiple adhesive pressing teeth 2211 are flat and smooth to ensure the flatness of the adhesive paper 30 being pressed. Optionally, the shape of the end face of the adhesive pressing column 221 and the shape of the end faces of the multiple adhesive pressing teeth 2211 match the shape of the tab end face (i.e., the end face of the battery cell 20). Optionally, in this embodiment, the adhesive pressing assembly 22 can be made of 304 stainless steel, bakelite, ceramic material, or stainless steel with a wear-resistant coating. This embodiment does not limit the specific material of the adhesive pressing assembly 22. Optionally, the adhesive receiving hole 1211 and the adhesive pressing post 221 are aligned along the axial direction of the battery cell 20, thereby ensuring that the adhesive pressing post 221 and the adhesive pressing teeth 2211 on the adhesive pressing post 221 pass through the adhesive receiving hole 1211.
[0052] Optionally, in this embodiment, as Figure 1 As shown, the battery cell coating device also includes a mounting base 3 and a guide rail 4. The mounting base 3 is equipped with a glue-collecting drive assembly 11 and a glue-pressing drive assembly 21. The guide rail 4 is mounted on the mounting base 3 and extends along the moving direction of the glue-collecting assembly 12 and the glue-pressing assembly 22, with both moving along the guide rail 4. By providing the guide rail 4 on the mounting base 3, the movement of the glue-collecting assembly 12 and the glue-pressing assembly 22 is guided, ensuring the reliability of the glue-collecting assembly 12 in folding the adhesive paper 30 and the reliability of the glue-pressing assembly 22 in pressing the adhesive paper 30. Furthermore, by having the glue-collecting assembly 12 and the glue-pressing assembly 22 share a single guide rail 4 for guidance, the structure becomes compact and simple. Optionally, in this embodiment, a first sliding groove 1221 is provided on the connecting plate 122, and the first sliding groove 1221 slides along the guide rail 4. Optionally, a second slide groove 2221 is provided on the mounting plate 222, and the second slide groove 2221 slides along the guide rail 4.
[0053] In this embodiment, as Figures 4-6 As shown, a glue-collecting mechanism 1 and a glue-pressing mechanism 2 are provided at both ends of the battery cell 20 in the axial direction. The glue-collecting mechanism 1 and the glue-pressing mechanism 2 are both provided on the mounting base 3 on the corresponding side, so that the glue-coating work is performed on both ends of the battery cell 20 in the axial direction at the same time, which effectively improves the glue-coating efficiency.
[0054] In this embodiment, as Figure 7 As shown, this embodiment also provides a method for coating battery cells with adhesive. This method is applied to the aforementioned battery cell coating apparatus and includes the following steps:
[0055] The adhesive collection drive assembly 11 drives the adhesive collection assembly 12 to move toward the end face of the battery cell 20, so that the wall of the adhesive collection hole 1211 folds the adhesive paper 30 extending out of the end face of the battery cell 20 toward the center hole of the battery cell 20.
[0056] The adhesive pressing drive assembly 21 drives the adhesive pressing assembly 22 to move toward the end face of the battery cell 20, so that the adhesive pressing assembly 22 passes through the adhesive receiving hole 1211 and presses the folded adhesive paper 30 onto the end face of the battery cell 20.
[0057] The battery cell coating method provided in this embodiment first drives the adhesive receiving component 12 to move closer to the end face of the battery cell 20 during the coating operation, so that the wall of the adhesive receiving hole 1211 folds the adhesive paper 30 extending from the end face of the battery cell 20 toward the center hole of the battery cell 20. Then, the adhesive pressing component 21 drives the adhesive pressing component 22 to move closer to the end face of the battery cell 20, so that the adhesive pressing component 22 passes through the adhesive receiving hole 1211 and presses the folded adhesive paper 30 onto the end face of the battery cell 20. This not only avoids the adhesive paper 30 extending from the end of the battery cell 20 from folding outwards during the adhesive pressing process, but also effectively ensures that the adhesive paper 30 extending from the end of the battery cell 20 can be completely adhered to the end face of the battery cell 20, improving the coating yield and coating consistency, and reducing the product scrap rate.
[0058] It should be noted that after the coating operation of the battery cell 20 is completed, the pressure drive assembly 21 drives the pressure assembly 22 to move and reset in the direction away from the end face of the battery cell 20, and then the glue collection drive assembly 11 drives the glue collection assembly 12 to move and reset in the direction away from the end face of the battery cell 20, so as to facilitate the corresponding coating operation for the next battery cell 20.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
