Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, and in particular to a battery electrolyte wetting device. Background Technology

[0002] In the production process of lithium-ion batteries, electrolyte is usually injected into the battery and then left to stand for a period of time to allow the electrolyte to fully wet the electrode plates. If the wettation is insufficient, it may lead to the formation of black spots at the interface, increased internal resistance, reduced capacity, and directly reduced battery life.

[0003] Currently, most methods employ a settling process to impregnate the electrolyte, primarily using ovens or temperature-controlled chambers for either room temperature or high-temperature settling. Room temperature settling typically requires 20 to 80 hours, which is time-consuming and impacts lithium battery production efficiency. High-temperature settling, where the battery remains at a high temperature for an extended period, increases electrolyte side reactions, leading to a decrease in battery performance across various aspects. To address these issues, existing technologies typically design electrolyte impregnation devices that rotate the batteries. After electrolyte injection, the batteries are not settling but are instead transferred into the device's clamps. At room temperature or high temperature, a rotating drum increases electrolyte flow within the battery, promoting diffusion and impregnation of the organic electrolyte into the battery interior, particularly in the gaps between the electrodes and separator, effectively shortening the settling time. However, current electrolyte impregnation devices can only connect to a single rotating shaft in their clamps, and the clamping capacity of a single clamp is limited, resulting in an insufficient number of batteries simultaneously undergoing electrolyte impregnation, thus affecting production efficiency.

[0004] Therefore, this application aims to provide a battery electrolyte wetting device to solve the above-mentioned problems. Utility Model Content

[0030] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0031] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly and specifically defined.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, 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 according to the specific circumstances.

[0033] 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.

[0034] Please see Figures 1 to 6In this embodiment, a battery electrolyte wetting device is provided to optimize the penetration effect of electrolyte on materials such as electrode sheets and separators during the production of battery 4, thereby improving the production efficiency of battery 4. The device includes a support frame 1, which includes a bracket 10 and a rotating frame 11. The rotating frame 11 is rotatably connected to the bracket 10 via a rotating shaft 111. The rotating frame 11 has a mounting surface 110 arranged circumferentially. Clamps 2 are used to clamp the battery 4, and multiple clamps 2 are fixedly connected to the mounting surface 110. A driving member 3 is connected to the rotating shaft 111, and the rotating shaft 111 drives the rotating frame 11 to rotate under the drive of the driving member 3.

[0035] In this embodiment, the support frame 1 supports the entire device. The support frame 1 includes a bracket 10 and a rotating frame 11. The rotating frame 11 can carry the clamps 2 and batteries 4, and is connected to the bracket 10 via a rotating shaft 111 to achieve rotational movement. The bracket 10 provides stable support for the rotating frame 11 and resists the torque generated by the rotation of the rotating frame 11. The mounting surface 110 is a circumferential plane of a cylinder or polygonal prism, used to mount multiple clamps 2. Multiple clamps 2 can hold multiple batteries 4, enabling mass production and improving the production efficiency of the batteries 4. The rotating frame 11 is fixed to the rotating shaft 111 to ensure synchronous power transmission. The clamps 2 can hold the batteries 4, fixing their position and preventing them from shifting or falling during rotation. The clamps 2 are fixed to the mounting surface 110 of the rotating frame 11 and can rotate synchronously with the rotating frame 11. The driving component 3 provides rotational power to the rotating frame 11 and controls the rotation speed and direction of rotation of the rotating frame 11. For example, the driving component 3 is a motor.

[0036] In the above embodiment, the motor provides driving force to drive the rotating shaft 111 to rotate. The rotating shaft 111 is fixed to the rotating frame 11, thereby driving the rotating frame 11 to rotate. Since the clamp 2 is mounted on the mounting surface 110 of the rotating frame 11, when the rotating frame 11 rotates, it drives the clamp 2 to rotate, thereby driving the battery 4 to rotate. When the battery 4 rotates, the resulting centrifugal force forces the electrolyte to diffuse into the gaps on the battery 4 electrodes. Under the action of centrifugal force, the surface tension of the electrolyte is overcome, the wetting angle between the electrolyte and the electrode is reduced, the filling effect of the electrolyte on the electrode gaps is enhanced, and the electrolyte penetration time is shortened. The wetting angle, also known as the contact angle, refers to the angle formed at the contact point between the liquid-gas interface and the solid-liquid interface when the liquid reaches equilibrium on the solid surface.

[0037] It should be noted that since the battery electrolyte wetting device overcomes the surface tension of the electrolyte and allows it to enter the electrode gap under the drive of centrifugal force, the rotation speed of the battery electrolyte wetting device is determined according to the characteristics of the battery 4 itself, such as the size of the battery 4 and the thickness of the electrodes. This application does not specifically limit the rotation speed of the rotating frame 11, as long as the lower limit of the rotation speed can overcome the surface tension of the electrolyte and the upper limit of the rotation speed can prevent the electrolyte from being thrown out of the electrodes or generating bubbles.

[0038] In the above embodiments, the battery electrolyte wetting device is provided with a rotating frame 11, and the rotating frame 11 is provided with a mounting surface 110 in the circumferential direction. The mounting surface 110 is used to install multiple clamps 2. Compared with the method of connecting a single clamp 2 to a single rotating shaft 111, the mounting surface 110 can install multiple clamps 2, so that the battery electrolyte wetting device can hold more batteries 4, realize the mass production of batteries 4, and thus improve production efficiency.

[0039] Please see Figures 1 to 6 In one embodiment, the rotating frame 11 is a polygonal column with all its sides being the mounting surfaces 110, and each side is connected to at least one independent clamp 2.

[0040] In this embodiment, the rotating frame 11 is a polygonal column. Compared with the circumferential curved surface of a cylinder, the side surface of the polygonal column is a plane composed of various edges, which is easier to install and can be adapted to various types of clamps 2.

[0041] It should be noted that this application does not limit the specific shape of the polygonal prism. For example, the polygonal prism can be a triangular prism, a quadrangular prism, a hexagonal prism, or an octagonal prism, with a cross-section of a triangle, a rectangle, a regular polygon, or other regular / irregular polygons, used to fix the clamp 2 and rotate synchronously with the rotating frame 11.

[0042] Specifically, in the above embodiments, the number of clamps provided on the side is set according to actual needs. A side may have only one independent clamp 2, or multiple independent clamps 2 may be provided on a side.

[0043] Please see Figures 1 to 6 In one embodiment, the rotating frame 11 is provided with a shaft hole along the axial direction, and the rotating shaft 111 passes through the shaft hole and is rotatably connected to the bracket 10; the rotating shaft 111 is fixedly connected to the inner sidewall of the shaft hole.

[0044] In this embodiment, the shaft hole is located at the geometric center of the axial end face of the rotating frame 11, which can ensure that the rotating frame 11 will not generate unbalanced torque caused by centrifugal force during rotation, thereby avoiding vibration and preventing the battery 4 from leaking or being damaged due to vibration displacement.

[0045] It should be noted that the rotating shaft 111 can be part of the rotating frame 11. When the shaft hole is not provided, the rotating shaft 111 is a column protruding outward from the geometric center of the axial end face of the rotating frame 11. Since the rotating shaft 111 and the rotating frame 11 need to be replaced together when the rotating frame 11 is replaced, materials are easily wasted and the usage cost is high. Therefore, by providing the shaft hole as described above, only the rotating frame 11 needs to be replaced and the rotating shaft 111 does not need to be replaced, which helps to save costs.

[0046] In the above embodiments, the rotating shaft 111 is fixedly connected to the inner wall of the shaft hole, ensuring that the rotating frame 11 rotates with the rotating shaft 111. For example, a through hole can be provided on the corresponding circumferential surface of the rotating shaft 111 and the shaft hole, and a fixing rod can be passed through the through hole to fix the rotating shaft 111 to the shaft hole; alternatively, a limiting groove can be provided on the inner wall of the shaft hole, and a limiting block 202 can be provided on the rotating shaft 111, with the limiting block 202 engaging with the limiting groove to achieve a fixed connection.

[0047] Please see Figures 1 to 6 In one embodiment, the rotating frame 11 is provided with an annular bushing along the axial direction, the central hole of the annular bushing is the shaft hole, and the annular bushing is connected to the mounting surface 110 by a plurality of support ribs 112 to support the mounting surface 110.

[0048] In this embodiment, the support rib 112 can be a rib plate, extending axially or radially along the rotating frame 11, connecting the mounting surface 110 and the annular bushing. For example, when the rotating frame 11 is a hexagonal prism structure, in the hexagonal prism rotating frame 11, a rib plate corresponds to the edge of the hexagonal prism along the length direction of the rotating frame 11, with one end connected to the inner edge and the other end connected to the outer wall of the annular bushing.

[0049] In the above embodiment, a plurality of support ribs 112 are provided, and weight-reducing holes are formed between adjacent support ribs 112, which can effectively reduce the weight of the rotating frame 11 and save the manufacturing cost of the rotating frame 11.

[0050] Please see Figures 1 to 6 In one embodiment, the clamp 2 includes multiple clamping plates 20 and multiple fixing members. The clamping plates 20 are provided with fastening holes 200. The multiple clamping plates 20 are stacked, and a clamping space is formed between the clamping plates 20 that are arranged opposite to each other to clamp the battery 4. The fixing members pass through the fastening holes 200 to fix the multiple stacked clamping plates 20.

[0051] In this embodiment, the fastening hole 200 can be a threaded hole or a smooth through hole. The fastener can be a screw 211, which can have threads at both ends and a smooth structure between the ends, or a structure whose entire surface is threaded.

[0052] In the above embodiment, the clamp 2 consists of stacked clamping plates 20, with a clamping space formed between the opposing clamping plates 20, capable of clamping the battery 4. The overall structure of the clamp 2 clamping the battery 4 is a structure in which the battery 4 and the clamping plates 20 are stacked alternately, with the bottom and top being clamping plates 20. The battery 4 is placed between the clamping plates 20, and the screw 211 passes through the fastening hole 200 and is fixed to the mounting surface 110 by thread, thus initially fixing the clamp 2 and the clamped battery 4.

[0053] Specifically, in the above embodiment, the fastening holes 200 can be located at the four corners of the clamping plate 20, and correspondingly, the number of fasteners is the same as the number of fastening holes 200. In actual use, four fasteners can pass through the fastening holes 200 at the four corners of the clamping plate 20 and be fixed to the mounting surface 110 to fix multiple stacked clamping plates 20.

[0054] Please see Figures 1 to 6 In one embodiment, the clamp 2 further includes a plurality of fasteners adapted to the fixing member, the fasteners being securely connected to the fixing member near the end of the top clamping plate to secure the clamping plate 20.

[0055] In the above embodiment, the fastener can be a nut 210, the number of which is the same as that of the fixing member. The nut 210 is fastened to the fixing member at the top of the clamp 2, which can provide clamping force for the clamp 2 to clamp the battery 4, so as to ensure that the clamp 2 clamps the battery 4.

[0056] Please see Figures 1 to 6 In one embodiment, a limiting block 202 is provided on one side of the clamping plate 20. The limiting block 202 is provided along the length direction of the clamping plate 20 and is respectively provided on the edge of the two long sides.

[0057] In this embodiment, the clamping plate 20 is designed according to the structure of the battery 4, and its large surface is used to directly contact and fix the battery 4. The limiting block 202 is a protruding structural block used to limit the position of the battery 4, prevent the battery 4 from sliding or shifting when clamped by the clamping plate 20, and further prevent the clamp 2 from disengaging from the clamping plate 20 when rotating with the rotating frame 11.

[0058] It should be noted that the limiting block 202 and the clamping plate 20 can be an integral structure or a detachable structure connected by bolts.

[0059] Please see Figures 1 to 6 In one embodiment, the clamping plate 20 is provided with adjustment holes 201, which are located at both ends of the clamping plate 20 along its length, and the two ends of the limiting block 202 are respectively fixedly connected to the adjustment holes 201.

[0060] In this embodiment, the adjustment hole 201 is used to cooperate with the limiting block 202 to adjust the size of the clamping surface of the clamping plate 20, thereby accommodating batteries 4 of different widths. In actual use, the limiting block 202 is provided with a threaded hole relative to the adjustment hole 201. When the adjustment hole 201 cooperates with the limiting block 202, the position of the limiting block 202 is determined according to the width of the battery 4. After the position of the limiting block 202 is determined, it can be fastened by bolts passing through the adjustment hole 201 and the threaded hole on the limiting block 202, so as to fix the limiting block 202 and the clamping plate 20.

[0061] In the above embodiments, the adjustment hole 201 can be a single oval hole for easy adjustment; or it can be multiple through holes on a line. An oval hole refers to a hole with semicircular ends and a rectangular middle section, where the diameters of the two semicircles are equal, and the length of the rectangular middle section is greater than the diameter of the semicircles.

[0062] Please see Figures 1 to 6 In one embodiment, the drive member 3 is connected to the rotating shaft 111 via the drive shaft 30.

[0063] In this embodiment, the drive shaft 30 can be a coupling, the drive component 3 is a motor, the output shaft of the motor is movably connected to the coupling, and the other end of the coupling is connected to the rotating shaft 111. The coupling can compensate for the axial deviation between the drive component 3 and the rotating shaft 111 (such as radial deviation ±0.1mm), reduce vibration, and achieve precise alignment between the output shaft of the motor and the rotating shaft 111.

[0064] Please see Figures 1 to 6 In one embodiment, a driven gear is provided on the axial end face of one end of the rotating shaft 111, and a driving gear is provided on the axial end face of one end of the drive shaft 30. The driving gear and the driven gear are meshed and connected.

[0065] In this embodiment, the drive shaft 30 is the output shaft of the drive component 3. The drive shaft 30 is connected to the rotating shaft 111 via gears. By adjusting the gear ratio of the driving gear and the driven gear, speed can be changed or torque can be altered. When torque needs to be changed, the gears can be replaced to achieve the desired match, without needing to replace the motor. For example, in the battery electrolyte wetting device for battery 4, if low speed and high torque are required (suitable for thick electrode batteries 4), the rotational speed can be reduced and the torque increased through gear transmission.

[0066] Please see Figures 1 to 6 In one embodiment, a driven sprocket is provided on the axial end face of one end of the rotating shaft 111, and a driving sprocket is provided on the axial end face of one end of the drive shaft 30. The driving sprocket and the driven sprocket are connected by a chain.

[0067] In this embodiment, the drive shaft 30 is the output shaft of the drive component 3, and the connection between the rotating shaft 111 and the drive shaft 30 is achieved by chain drive. The chain can span a larger distance, which facilitates the installation of the motor; at the same time, when replacing the chain, high-precision alignment is not required, which facilitates maintenance.

[0068] The actual usage process of this battery electrolyte wetting device is as follows:

[0069] After the battery 4 is filled with electrolyte, the first clamping plate 20 is installed on the mounting surface 110 of the rotating frame 11. The first clamping plate 20 is fixed to the mounting surface 110 by passing screws 211 through the through holes at the four corners of the first clamping plate 20 to position it and prevent it from moving. The battery 4 is placed on the large surface of the first clamping plate 20, and then the second clamping plate 20 is pressed onto the battery 4 by passing screws 211 through the through holes at the four corners. The battery 4 is then placed on the large surface of the second clamping plate 20. This process is repeated until the battery 4 and the clamping plate 20 are stacked to the mark on the screw 211. Finally, the screw 211 is tightened with nuts 210. After checking that everything is correct, the parameters are set and the battery electrolyte immersion device is turned on.

[0070] In summary, an embodiment of this application provides a battery electrolyte wetting device, comprising a support frame 1, which includes a bracket 10 and a rotating frame 11. The rotating frame 11 is rotatably connected to the bracket 10 via a rotating shaft 111. The rotating frame 11 has a mounting surface 110 circumferentially arranged. Clamps 2 are used to hold batteries 4, and multiple clamps 2 are fixedly connected to the mounting surface 110. A driving member 3 is connected to the rotating shaft 111, and the rotating shaft 111 rotates under the drive of the driving member 3. This technical solution provides a rotating frame 11 with a mounting surface 110 circumferentially arranged. The mounting surface 110 is used to mount multiple clamps 2. Compared to a single clamp 2 connected to a single rotating shaft 111, the mounting surface 110 can mount multiple clamps 2, enabling the battery electrolyte wetting device to hold more batteries 4, achieving mass production of batteries 4 and improving production efficiency.
