[0020] The embodiments of this application will now be described in detail. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

Furthermore, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] In the battery pack manufacturing process, such as Figure 1As shown, a battery cell module 1 is formed by stacking multiple battery cells along the second direction Y. End plates 3 are respectively disposed on both sides of the battery cell module 2 along the first direction X. Adhesive is applied to the side of the end plates 3 facing the battery cell module 2, and then the end plates 3 are glued to both sides of the battery cell module 2 along the first direction X, thereby forming the entire battery cell module 1. In this process, the adhesive needs to be cured using a curing process to shorten the curing time, and the width of the entire battery cell module 1 along the first direction X must meet the design requirements.

[0025] In related technologies, end plates 3 are coated with adhesive and then attached to both sides of the cell assembly 2. They are then transferred to a curing oven via a transfer device to cure the adhesive. However, during the transfer process, the adhesive may not fully cure, potentially causing misalignment of the cells. This results in the cell module 1, after curing in the oven, not meeting design requirements, leading to a high product scrap rate.

[0026] Based on this, this application proposes a cell curing device to solve some or all of the above-mentioned technical problems.

[0027] The battery cell curing apparatus provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0028] like Figure 2 As shown in the figure, this application provides a battery cell curing device, including a base 10, a clamping assembly 20, and a curing element 30. The clamping assembly 20 is disposed on and connected to the base 10. The clamping assembly 20 has a clamping space A for placing a battery cell module 1. The clamping assembly 20 is at least partially movable relative to the base 10 to adjust the size of the clamping space A. The curing element 30 is disposed on at least one side of the clamping assembly 20 and is connected to the base 10. The curing element 30 is used to output energy into the clamping space A to cure the battery cell module 1.

[0029] In this embodiment, by providing a clamping assembly 20 on the base 10 and a clamping space A within the clamping assembly 20, the battery cell module 1 can be placed into the clamping space A. By enabling at least a portion of the clamping assembly 20 to move relative to the base 10, the size of the clamping space A is changed, thereby achieving compression and clamping of the battery cell module 1. By providing a curing element 30 on at least one side of the clamping assembly 20, the curing element 30 can output energy to the clamping space A. The energy of the curing element 30 acts on the adhesive in the battery cell module 1, thereby curing the adhesive in the battery cell module 1. Compared to related technologies, the battery cell curing device of this application, during the curing process of the battery cell module 1 using the curing element 30, clamps and fixes the battery cell module 1 using the clamping assembly 20, ensuring that the width of the battery cell module 1 meets the design requirements, avoiding misalignment of the battery cells in the battery cell module 1, thereby reducing product scrap rate and improving product yield.

[0030] like Figure 2 As shown, the cell curing device includes a base 10, a clamping assembly 20, and a curing component 30. The base 10 is a structure that supports and mounts other components. Exemplarily, the base 10 can be a base plate, a base, or other structures that can support and mount other components. The embodiments of this application do not limit the specific structure of the base 10.

[0031] like Figure 2 As shown, the clamping assembly 20 is connected to the base 10, and a clamping space A is provided in the clamping assembly 20, into which the battery cell module 1 can be placed. At least a portion of the clamping assembly 20 is movable relative to the base 10, thereby changing the size of the clamping space A, thus achieving compression and clamping of the battery cell module 1 within the clamping space A. Exemplarily, at least a portion of the clamping assembly 20 can be slidably connected to the base 10, thereby enabling sliding and changing the size of the clamping space A.

[0032] like Figure 2 As shown, the curing component 30 is connected to the base 10 and located on at least one side of the clamping assembly 20, so that the curing component 30 can output energy from at least one side of the clamping assembly 20 into the clamping space A of the clamping assembly 20. The energy acts on the adhesive in the cell module 1, which can cure the adhesive, thereby achieving the bonding between the cell assembly 2 and the end plate 3 to form the cell module 1.

[0033] In some embodiments, such as Figure 2 As shown, the curing element 30 can be disposed on one side of the clamping assembly 20 along the first direction X. In this case, the curing element 30 can only cure the adhesive in the cell module 1 from one side.

[0034] In other embodiments, such as Figure 2As shown, the curing element 30 can be disposed on both sides of the clamping assembly 20 along the first direction X. In this case, the curing element 30 can cure the adhesive in the battery cell module 1 from both sides.

[0035] In some embodiments, the adhesive in the battery cell module 1 can be a thermosetting adhesive (e.g., a hot vulcanizing adhesive), and the curing component 30 is a component that can be heated. By heating the thermosetting adhesive, the thermosetting adhesive is cured, thereby achieving a firm bond between the battery cell module 2 and the end plate 3.

[0036] In some other embodiments, the adhesive in the battery cell module 1 can be a light-curing adhesive (e.g., UV adhesive). UV adhesive is an adhesive that can only be cured by ultraviolet light irradiation. The curing component 30 is a component that can emit UV light (ultraviolet light). By irradiating the UV adhesive with UV light, the UV adhesive is cured, thereby achieving a firm bond between the battery cell module 2 and the end plate 3.

[0037] Of course, the adhesive in the cell module 1 can also be other types of adhesive, as long as it can bond the cell assembly 2 to the end plate 3. The curing component 30 is the component that cures the adhesive. The specific type of the curing component 30 can be flexibly set according to the type of adhesive, and this embodiment does not limit it.

[0038] Optionally, such as Figure 2 , Figure 3 and Figure 4 As shown, the base 10 has a first direction X, and the clamping assembly 20 includes a support member 21 and a clamping member 22 spaced apart along the first direction X. A clamping space A is formed between the support member 21 and the clamping member 22. The support member 21 is fixedly connected to the base 10, and the clamping member 22 is slidably connected to the base 10 along the first direction X. The curing member 30 is disposed on the side of the support member 21 away from the clamping space A and is connected to the base 10.

[0039] In this embodiment, a clamping space A is formed by spacing the support member 21 and the clamping member 22 along a first direction X. By fixing the support member 21 to the base 10 and slidably connecting the clamping member 22 to the base 10, the clamping member 22 can slide relative to the support member 21, moving closer to or further away from the support member 21, thus changing the size of the clamping space A. This allows for the compression and clamping of the battery cell module 1 placed in the clamping space A. By positioning the curing member 30 on the side of the support member 21 away from the clamping space A, the curing member 30 outputs energy from one side of the support member 21 into the clamping space A, thereby curing the adhesive on the side of the battery cell module 1 facing the support member 21.

[0040] For example, such as Figure 2 , Figure 3 and Figure 4As shown, the support member 21 can be a plate-like structure, and it is fixed to the base 10. The two can be fixed together by bolts. The clamping member 22 can also be a plate-like structure, and it is slidably connected to the base 10, for example, by a guide rail slider structure. Of course, the fixing method of the support member 21 and the base 10, as well as the sliding connection method of the clamping member 22 and the base 10, can be flexibly set according to the actual situation, and this embodiment does not limit this.

[0041] It should be noted that the direction in which the support member 21 and the clamping member 22 are spaced apart is consistent with the direction in which the cell assembly 2 and the end plate 3 are spaced apart, both being arranged along the first direction X. This allows the clamping member 22 to squeeze and clamp the cell assembly 2 and the end plate 3 when it is close to the support member 21, so that the width of the cell module 1 along the first direction X can meet the design requirements.

[0042] Optionally, such as Figure 2 , Figure 3 and Figure 4 As shown, the curing component 30 is located on the side of the clamping component 22 away from the clamping space A and is connected to the base 10.

[0043] In this embodiment, by positioning the curing member 30 on the side of the clamping member 22 away from the clamping space A, the curing member 30 can output energy from one side of the clamping member 22 to the clamping space A, thereby achieving the curing of the adhesive on the side of the battery cell module 1 facing the clamping member 22.

[0044] Of course, the curing component 30 can be disposed on the side of the support component 21 away from the clamping space A, or on the side of the clamping component 22 away from the clamping space A, or simultaneously disposed on both sides of the clamping assembly 20 along the first direction X. The specific placement of the curing component 30 can be flexibly set according to the actual situation, and this application embodiment does not limit it in this regard.

[0045] Optionally, such as Figure 5 As shown, the cell curing device also includes a drive assembly 40, which is disposed on and connected to the base 10. The drive assembly 40 is connected to the clamping member 22 and is used to drive the clamping member 22 to move.

[0046] In this embodiment, the drive component 40 is connected to the clamping member 22, enabling the drive component 40 to drive the clamping member 22 to move, thereby changing the size of the clamping space A. By using the drive component 40 for driving, the clamping member 22 does not need to be pushed by hand by the operator, which is simple, convenient, and saves manpower.

[0047] Optionally, such as Figure 5As shown, the drive assembly 40 includes a pusher 41, a connector 42, and a drive member 43; a curing member 30 is provided on the side of the clamping member 22 away from the clamping space A, the pusher 41 is provided on the side of the curing member 30 away from the clamping member 22, the pusher 41 is slidably connected to the base 10, one end of the connector 42 is connected to the pusher 41, and the other end of the connector 42 is connected to the clamping member 22; the drive member 43 is connected to the pusher 41 and is used to drive the pusher 41 to move.

[0048] In this embodiment, the pusher 41 is located on the side of the cured member 30 opposite to the clamping member 22 and is slidably connected to the base 10. The pusher 41 and the clamping member 22 are connected by the connector 42, thus connecting the clamping member 22, the connector 42, and the pusher 41 together. The drive member 43 is connected to the pusher 41, providing a driving force to the pusher 41, thereby driving the pusher 41 to move. The pusher 41 drives the connector 42 and the clamping member 22 to move together, transmitting power to the clamping member 22 and realizing its movement. In this structure, the pusher 41 and the clamping member 22 are connected by the connector 42, forming a frame structure, allowing the drive member 43 to pass over the cured member 30 and transmit power to the clamping member 22.

[0049] Specifically, such as Figure 5 As shown, the curing component 30 is disposed on the side of the clamping component 22 opposite to the clamping space A, and the connecting component 42 connects the pushing component 41 and the clamping component 22. Multiple connecting components 42 can be provided, spaced apart along the second direction Y, to connect the pushing component 41 and the clamping component 22 and improve the connection strength.

[0050] For example, such as Figure 5 As shown, there are three connectors 42. One connector 42 can be located on one side of the cured component 30 along the third direction Z, and the other two connectors 42 can be located on both sides of the cured component 30 along the second direction Y.

[0051] For example, the driving component 43 can be a cylinder, an electric push rod, or a lead screw or screw, as long as it can drive the push component 41. The specific structure of the driving component 43 can be flexibly set according to the actual situation, and this application embodiment does not limit it.

[0052] Optionally, such as Figure 5As shown, the pushing member 41 includes a first pushing plate 411, a second pushing plate 412, and a pressure detection member 413. The first pushing plate 411 is disposed on the side of the curing member 30 away from the clamping member 22, and the second pushing plate 412 is disposed on the side of the first pushing plate 411 away from the curing member 30. The first pushing plate 411 is connected to the connecting member 42, and the second pushing plate 412 is connected to the driving member 43. The pressure detection member 413 is connected between the first pushing plate 411 and the second pushing plate 412 and is used to detect the pressure between the first pushing plate 411 and the second pushing plate 412.

[0053] In this embodiment, the connection between the pusher 41 and the connector 42 is achieved by connecting the first pusher 411 to the connector 42 and the second pusher 412 to the drive member 43. By connecting the pressure detection member 413 between the first pusher 411 and the second pusher 412, the pressure between the first pusher 411 and the second pusher 412 can be detected. This pressure is also the squeezing force exerted by the clamping member 22 on the cell module 1, thus facilitating the detection and recording of the squeezing force on the cell module 1.

[0054] Specifically, such as Figure 5 As shown, the first push plate 411 is connected to the connecting member 42 and slides relative to the base 10. The second push plate 412 is connected to the driving member 43 and slides relative to the base 10. When the driving member 43 drives the second push plate 412 to move, the first push plate 411 can be pushed by the pressure detection member 413, and then the power is transmitted to the clamping member 22 through the connecting member 42. In addition, a display can be provided on the base 10 to display the pressure detected by the pressure detection member 413 for the convenience of the operator.

[0055] Optionally, the curing component 30 is a photocatalytic curing component, which is used to irradiate light into the clamping space A to cure the battery cell module 1.

[0056] In this embodiment, by making the curing component 30 a photocatalytic curing component, the photocurable adhesive can be cured through photocatalysis. Under light irradiation, the photocurable adhesive can cure within a few seconds to tens of seconds, greatly shortening the curing time, thereby shortening the production cycle and improving production efficiency.

[0057] Specifically, the end plate 3 is coated with a light-curing adhesive, such as UV adhesive, and the curing component 30 is a photocatalytic curing component, such as a UV light emitting lamp.

[0058] In some embodiments, the curing component 30 is a UV light emitting lamp. The UV light emitting lamp generates significant heat during operation, causing its temperature to rise. Therefore, heat dissipation holes can be made on the outer wall of the UV light emitting lamp, and then a cooling fan 60 can be installed. The cooling fan 60 effectively dissipates heat from the UV light emitting lamp, thereby suppressing its temperature rise.

[0059] It should be noted that when using photocurable adhesive, end plate 3 should be transparent so that the light from the photocatalytic curing component can pass through end plate 3 and irradiate the photocurable adhesive.

[0060] Optionally, such as Figure 3 and Figure 4 As shown, the clamping assembly 20 also includes a light-transmitting element 23. The support member 21 has a curing element 30 on the side opposite to the clamping space A. The support member 21 has a first through hole 211 that runs through the first direction X. The light-transmitting element 23 is located in the first through hole 211 and connected to the support member 21. The light from the curing element 30 can pass through the light-transmitting element 23 and irradiate the clamping space A.

[0061] In this embodiment of the application, by providing a first through hole 211 extending along the first direction X on the support member 21 and placing the light-transmitting member 23 in the first through hole 211, the light from the curing member 30 can pass through the light-transmitting member 23 and irradiate the clamping space A, so that the light from the curing member 30 irradiates the end plate 3 on one side of the battery cell module 1, thereby achieving curing of the photocurable adhesive.

[0062] For example, the light-transmitting element 23 can be connected to the support element 21 in a detachable manner, such as by using a clip to secure the light-transmitting element 23 in the first through hole 211, which facilitates disassembly and assembly.

[0063] Optionally, such as Figure 3 and Figure 4 As shown, the clamping member 22 has a curing member 30 on the side away from the clamping space A. The clamping member 22 has a second through hole 221 that runs through the first direction X. The light-transmitting member 23 is located in the second through hole 221 and connected to the clamping member 22. The light from the curing member 30 can pass through the light-transmitting member 23 and irradiate the clamping space A.

[0064] In this embodiment of the application, by providing a second through hole 221 that extends along the first direction X on the clamping member 22, and placing the light-transmitting member 23 in the second through hole 221, the light from the curing member 30 can pass through the light-transmitting member 23 and irradiate the clamping space A, so that the light from the curing member 30 irradiates the end plate 3 on the other side of the battery cell module 1, thereby achieving curing of the photocurable adhesive.

[0065] Similarly, the light-transmitting element 23 and the clamping element 22 can also be detachably connected, and their working principle can be implemented with reference to the above embodiments, which will not be repeated here.

[0066] Optionally, such as Figure 3 and Figure 4 As shown, the end face of the light-transmitting element 23 facing the clamping space A is a plane.

[0067] In this embodiment, by setting the end face of the light-transmitting element 23 facing the clamping space A to be a plane, the end plate 3 of the battery cell module 1 is squeezed using a plane, avoiding the situation where the width of the battery cell module 1 along the first direction X is inconsistent when the end plate 3 is squeezed using a concave, convex or irregular surface. This makes it easier to ensure the width of the battery cell module 1 along the first direction X, thereby meeting the design requirements.

[0068] It should be noted that the orthographic projection of the plane along the first direction X can completely cover the orthographic projection of the end plate 3 along the first direction X, thereby ensuring that the end face of the end plate 3 along the first direction is squeezed by the plane and avoiding local squeezing.

[0069] Optionally, such as Figure 5 As shown, the cell curing device also includes a limiting member 50, which is disposed between the support member 21 and the clamping member 22. The limiting member 50 is connected to the base 10 and is used to limit the relative displacement between the support member 21 and the clamping member 22.

[0070] In this embodiment, by providing a limiting member 50 between the support member 21 and the clamping member 22, the limiting member 50 can play a limiting role when the clamping member 22 approaches the support member 21, thereby preventing the clamping member 22 and the support member 21 from excessively squeezing the battery cell module 1.

[0071] Specifically, the length of the limiting member 50 along the first direction X is the width of the extruded battery cell module 1 along the first direction X. Therefore, the length of the limiting member 50 along the first direction X can be equal to the width required by the design. One end of the limiting member 50 along the first direction X abuts against the support member 21. When the clamping member 22 approaches the support member 21 and abuts against the limiting member 50, it indicates that the extruded battery cell module 1 meets the design requirements.

[0072] It should be noted that when the clamping member 22 is far away from the support member 21, it can also be limited by the limiting member, which will not be described in detail here.

[0073] Optionally, such as Figure 5 As shown, the clamping assembly 20 also includes a guide 24 extending along the first direction X. The guide 24 is disposed on the side of the support 21 facing the clamping member 22 and is connected to the support 21. The clamping member 22 is provided with a guide hole extending along the first direction X, and the guide 24 passes through the guide hole to be slidably connected with the clamping member 22.
