Description

Technical Field

[0002] During the battery production process, electrolyte needs to be injected into the battery through the injection port on the battery first, and then the injection port is sealed after the injection is completed. Usually, the diameter of the injection nozzle of the injection equipment will be larger than the diameter of the injection port. During the injection process, some electrolyte will overflow to the surface of the battery, resulting in electrolyte residue near the injection port. If the residual electrolyte cannot be cleaned up in time, the electrolyte will solidify on the surface of the battery and cannot be removed. When the injection port is subsequently sealed, the dried electrolyte will cause a greater risk of poor sealing of the injection port.

[0058] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0059] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0060] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0061] It should be understood that the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0062] During the battery production process, electrolyte needs to be injected into the battery through the injection port on the battery first, and then the injection port is sealed after the injection is completed. Usually, the diameter of the injection nozzle of the injection equipment will be larger than the diameter of the injection port. During the injection process, some electrolyte will overflow to the surface of the battery, resulting in electrolyte residue near the injection port. If the residual electrolyte cannot be cleaned up in time, the electrolyte will solidify on the surface of the battery and cannot be removed. When the injection port is subsequently sealed, the dried electrolyte will cause a greater risk of poor sealing of the injection port.

[0063] In order to reduce the risk of poor sealing caused by electrolyte on the battery surface, the battery surface is usually wiped before the filling port is sealed. The most commonly used wiping method is manual wiping, which results in low battery cleaning efficiency, long cycle and high cost.

[0064] To this end, an embodiment of the present application provides a wiping tool, which can be used to wipe the electrolyte remaining on the surface of the battery. In addition, the wiping tool provided in the embodiment of the present application can also be used to wipe other objects, not limited to batteries.

[0065] like Figure 1 As shown, the wiping tool includes a rotating shaft assembly 1, a first transmission belt 2, a second transmission belt 4, a first driving member 3 and a second driving member 5, as shown in FIG. Figure 2 As shown, the shaft assembly 1 includes a main shaft 113, a rotating shaft 11 sleeved on the outside of the main shaft 113 and capable of rotating around the central axis of the main shaft 113, and a cleaning member 12 installed on the rotating shaft 11 and rotating synchronously with the rotating shaft 11. The cleaning member 12 is a cleaning sponge or a cleaning cloth, etc. The embodiment of the present application does not specifically limit the specific material of the cleaning member 12. Figure 1 As shown, the first transmission belt 2 is connected to the rotating shaft 11 and the first driving member 3 at both ends along its length direction, and the second transmission belt 4 is connected to the rotating shaft 11 and the second driving member 5 at both ends along its length direction.

[0066] refer to Figure 1When the wiping tool is working, the first driving member 3 rotates counterclockwise to drive the first transmission belt 2 to move. The rotating shaft 11 rotates counterclockwise around the central axis of the main shaft 113 under the pull of the first transmission belt 2, and drives the cleaning member 12 to rotate synchronously. At the same time, when the rotating shaft 11 rotates, it pulls the second transmission belt 4 to move and the second driving member 5 rotates counterclockwise. When the first driving member 3 and the second driving member 5 rotate at a preset angle, number of circles or time, the rotation direction of the second driving member 5 is adjusted to clockwise to drive the second transmission member to move. The rotating shaft 11 rotates clockwise around the central axis of the main shaft 113 under the pull of the second transmission belt 4, and drives the cleaning member 12 Synchronously rotate, at the same time, when the rotating shaft 11 rotates, it pulls the first transmission belt 2 to move and the first driving member 3 to rotate clockwise. When the first driving member 3 and the second driving member 5 rotate a preset angle, number of circles or time, the rotation direction of the first driving member 3 and the second driving member 5 is adjusted again, so that the rotating shaft 11 and the cleaning member 12 are changed to rotate counterclockwise again, that is, the rotating shaft 11 and the cleaning member 12 can be driven by the first transmission belt 2 and the second transmission belt 4 to rotate alternately in a clockwise and counterclockwise cycle to wipe the surface of the battery, thereby removing the residual electrolyte on the surface of the battery, thereby reducing the risk of poor sealing of the liquid filling port due to dried-up electrolyte.

[0067] In this embodiment, the movement of the first drive member 3, the second drive member 5, the first transmission belt 2, and the second transmission belt 4 drives the rotating shaft 11 to rotate, thereby driving the cleaning member 12 to rotate, so as to complete the wiping of the battery surface. Compared with manual wiping, the automated wiping method is conducive to improving wiping efficiency, shortening the wiping cycle, and reducing labor costs, thereby reducing the production cost of the battery. In addition, compared with existing large-scale equipment, the wiping tool in this embodiment has a simple structure and a small size, which improves portability, thereby reducing the restrictions on usage scenarios and usage space, and increasing the flexibility of the wiping tool. At the same time, the lower cost of the wiping tool further reduces the cleaning cost of the battery, thereby further reducing the production cost of the battery.

[0068] The rotation shaft 11 and the main shaft 113 are connected via a bearing, which can help improve the rotation stability of the rotation shaft 11 relative to the main shaft 113, thereby improving the working stability and reliability of the wiping tool.

[0069] like Figure 2 As shown, the rotating shaft 11 includes a rotating member 111 and a connecting member 112. The rotating member 111 is used to be rotatably connected to the main shaft 113. The cleaning member 12 is installed on the connecting member 112. The rotating member 111 and the connecting member 112 can be integrally formed to increase the stability of the structure of the rotating shaft 11. The rotating member 111 and the connecting member 112 can also be fixedly connected by fasteners such as screws, bolts, and pins to facilitate the disassembly and replacement of the rotating member 111 and the connecting member 112, thereby reducing the maintenance cost of the rotating shaft 11.

[0070] Among them, in one embodiment, in the plane where the axis of the cleaning member 12 is located, the cross-sectional shape of the cleaning member 12 is roughly concave, and the cleaning member 12 is directly sleeved on the outer surface of the connecting member 112 to simplify the connection method between the cleaning member 12 and the rotating shaft 11, thereby simplifying the structure of the cleaning member 12 and the connecting member 112 and reducing the cost of the wiping tooling.

[0071] In another embodiment, Figure 3 As shown, along the third direction Z (the third direction Z is parallel to the central axis of the main shaft 113), at least one connecting protrusion 112A is provided on the side of the connecting member 112 away from the rotating member 111, and at least one connecting fitting portion 121 is provided on the cleaning member 12, at least part of the connecting protrusion 112A is located in the connecting fitting portion 121 and abuts against the side wall of the connecting fitting portion 121, and the cleaning member 12 is fixed on the connecting member 112 by the fitting between the connecting protrusion 112A and the connecting fitting portion 121 to increase the connection stability between the cleaning member 12 and the connecting member 112, and at the same time, the connecting protrusion 112A and the connecting fitting portion 121 are used to limit the rotation of the cleaning member 12 relative to the rotating shaft 11 to improve the rotation consistency between the cleaning member 12 and the rotating shaft 11, thereby reducing the risk of the cleaning member 12 being unable to rotate under the influence of the friction force on the battery surface, resulting in the failure of the wiping tooling, thereby improving the working reliability of the wiping tooling, and thus helping to improve the processing yield of the battery.

[0072] In addition, in one embodiment, in the plane enclosed by the first direction X and the second direction Y, that is, in the plane perpendicular to the third direction, the cross-sectional shape of the connecting member 112 is circular, annular, triangular, quadrilateral or other deformed shapes, so as to facilitate the processing of the connecting member 112, thereby reducing the cost of the wiping tooling.

[0073] In another embodiment, Figure 4 As shown, the connecting member 112 includes a first connecting portion 112B, a second connecting portion 112C and a third connecting portion 112D. The first connecting portion 112B and the third connecting portion 112D are respectively located on both sides of the second connecting portion 112C. For example, the first connecting portion 112B and the third connecting portion 112D are respectively located at both ends of the second connecting portion 112C in the third direction Z. The first connecting portion 112B is connected to the rotating member 111, and the third connecting portion 112D is connected to the cleaning member 12. The outer diameter of the first connecting portion 112B and the outer diameter of the third connecting portion 112D are both larger than the outer diameter of the second connecting portion 112C. The first connecting portion 112B, the second connecting portion 112C and the third connecting portion 112D are connected to form an I-shaped structure.

[0074] In this embodiment, the I-shaped connecting member 112 can increase the contact area between the connecting member 112 and the rotating member 111, and the connecting member 112 and the cleaning member 12, which is beneficial to improving the connection stability between the connecting member 112 and the rotating member 111, and the connecting member 112 and the cleaning member 12. At the same time, the I-shaped structure can reduce the overall weight of the connecting member 112, so as to reduce the transportation and installation costs of the wiping tool.

[0075] Based on the shaft assembly 1 in any of the above embodiments, in a possible design, as Figure 1 As shown, there is only one rotating shaft assembly 1. In this case, the first transmission belt 2 and the second transmission belt 4 can be directly wound around the surface of the rotating shaft 11, that is, the first transmission belt 2 and the second transmission belt 4 are directly connected to the rotating shaft 11. The number of rotating shaft assembly 1 is only one, which further reduces the size of the wiping tool, reduces the restrictions on usage scenarios and usage space, and increases the flexibility of the wiping tool.

[0076] In another possible design, such as Figure 5 As shown, the number of the shaft components 1 is at least two, and the plurality of shaft components 1 are distributed along the first direction X; when the number of the shaft components 1 is multiple, as shown Figure 5 As shown, the shaft assembly 1 further includes a first rotating belt 13 and a second rotating belt 14. Figure 6 As shown, one end of the first rotating belt 13 is wound around the rotating shaft 11, and the first transmission belt 2 is indirectly connected to the rotating shaft 11 through the first rotating belt 13. One end of the second rotating belt 14 is wound around the rotating shaft 11, and the second transmission belt 4 is indirectly connected to the rotating shaft 11 through the second rotating belt 14.

[0077] In this embodiment, multiple rotating shaft assemblies 1 are provided, enabling the wiping tool to simultaneously wipe multiple batteries, thereby improving the efficiency of the wiping tool and thereby shortening the battery processing cycle. The first transmission belt 2 is connected to the rotating shaft 11 via a first rotating belt 13, and the second transmission belt 4 is connected to the rotating shaft 11 via a second rotating belt 14. This allows the number of first transmission belt 2 and second transmission belt 4 to be one, i.e., multiple rotating shaft assemblies 1 can be rotated by one first transmission belt 2 and one second transmission belt 4, thereby simplifying the structure of the wiping tool and reducing the cost of the wiping tool.

[0078] The first transmission belt 2 can be integrally formed with the first rotating belt 13 , and the second transmission belt 4 can be integrally formed with the second rotating belt 14 , so as to increase the connection stability between the first transmission belt 2 and the first rotating belt 13 , and between the second transmission belt 4 and the second rotating belt 14 .

[0079] The first transmission belt 2 and the first rotating belt 13 may also be fixedly connected by a fastening assembly, and the second transmission belt 4 and the second rotating belt 14 may also be fixedly connected by a fastening assembly. The fastening assembly includes but is not limited to a screw-nut matching structure, a bolt-nut matching structure, etc. The embodiment of the present application does not specifically limit the structure and type of the fastening assembly. The first transmission belt 2 and the first rotating belt 13, and the second transmission belt 4 and the second rotating belt 14 are fixedly connected by fasteners, which can facilitate the separate processing and replacement of the first transmission belt 2, the first rotating belt 13, the second transmission belt 4, and the second rotating belt 14, thereby reducing the processing cost of the first transmission belt 2, the first rotating belt 13, the second transmission belt 4, and the second rotating belt 14, and reducing the maintenance cost of the wiping tooling.

[0080] In any of the above embodiments, Figure 7 As shown, the wiping tool also includes a pipe 6, one end of which is connected to a liquid storage tank. The liquid storage tank stores cleaning liquid, and the pipe 6 is used to introduce the cleaning liquid into the cleaning member 12. The cleaning liquid can increase the cleaning effect of the wiping tool on the battery surface, thereby improving the wiping efficiency and yield of the wiping tool.

[0081] Among them, Figure 8 As shown, along the distribution direction of the first connection portion 112B and the third connection portion 112D, that is, along Figure 8 In the third direction Z, since the connecting member 112 is an I-shaped structure, the gap between the first connecting portion 112B and the third connecting portion 112D forms a receiving groove 112E, and the end of the pipe 6 away from the liquid storage tank is located in the receiving groove 112E. The pipe 6 is used to guide the cleaning liquid in the liquid storage tank into the receiving groove 112E; in addition, Figure 8 As shown, at least one channel 112F is provided on the third connecting portion 112D, and the channel 112F is connected to the receiving groove 112E. Along the distribution direction of the receiving groove 112E and the cleaning member 12, the channel 112F passes through the third connecting portion 112D, and the channel 112F is used to introduce the cleaning liquid in the receiving groove 112E into the cleaning member 12.

[0082] In this embodiment, pipe 6 extends into receiving groove 112E, directing cleaning liquid into receiving groove 112E. This reduces the risk of the cleaning liquid dripping directly onto the battery surface or even entering the battery interior, thereby improving battery operating stability and processing yield. The cleaning liquid within receiving groove 112E is directed into cleaning member 12 via hole 112F, increasing the speed at which the cleaning liquid enters cleaning member 12 and, in turn, improving the wiping efficiency of the wiping tool.

[0083] Specifically, if Figure 8As shown, the pipeline 6 includes a main pipe 61 and a first branch 62. The main pipe 61 is used to communicate with the liquid storage tank, and the first branch 62 is used to extend into the receiving groove 112E. In this case, one pipeline 6 is only used to introduce cleaning liquid into the receiving groove 112E of one shaft assembly 1, so as to simplify the structure of the pipeline 6 and reduce the cost of the pipeline 6. In another embodiment, as shown in FIG. Figure 9 As shown, the pipe 6 includes a main pipe 61, a first branch 62 and a second branch 63, and along the first direction X, the pipe 6 is located between two adjacent shaft assemblies 1, the first branch 62 is used to introduce cleaning liquid into the receiving groove 112E of one of the shaft assemblies 1, and the second branch 63 is used to introduce cleaning liquid into the receiving groove 112E of the other shaft assembly 1, that is, one pipe 6 introduces cleaning liquid into the receiving groove 112E of two adjacent shaft assemblies 1 at the same time, so as to reduce the number of pipes 6, thereby reducing the arrangement distance of the shaft assemblies 1 in the first direction X, so as to further reduce the size of the wiping tool.

[0084] Among them, when the number of shaft assemblies 1 is at least two, at least one shaft assembly 1 may need to be introduced with cleaning liquid to remove the electrolyte on the battery surface, and at least one shaft assembly 1 does not need to be introduced with cleaning liquid to wipe the battery surface dry.

[0085] In any of the above embodiments, when the wiping tool is used to wipe the battery, Figure 10 As shown, a sealing member 114 is connected to the main shaft 113, and at least a portion of the sealing member 114 is used to extend into the liquid filling port of the battery to seal the liquid filling port, thereby reducing the risk of cleaning liquid entering the interior of the battery through the liquid filling port during the wiping process, so as to improve the working stability of the battery, and also reduce the risk of the electrolyte inside the battery overflowing again during the wiping process, causing secondary contamination of the battery surface, so as to shorten the battery wiping cycle.

[0086] The connection structure between the main shaft 113 and the blocking member 114 is as follows: Figure 11 As shown, the main shaft 113 is provided with a first mounting groove 113A, one end of the blocking member 114 is located in the first mounting groove 113A, and the rotating shaft assembly 1 also includes an elastic member 115, the elastic member 115 is located in the first mounting groove 113A, and the two ends of the elastic member 115 are respectively in contact with the main shaft 113 and the blocking member 114.

[0087] In this embodiment, an elastic member 115 is provided between the main shaft 113 and the sealing member 114, so that there is flexible contact between the sealing member 114 and the battery, reducing the risk of the sealing damaging the battery surface or internal structure when the wiping tool is pressed down, thereby improving the wiping yield of the wiping tool and the processing yield of the battery.

[0088] like Figure 11As shown, at least one sealing member 116 is sleeved on the outside of the blocking member 114, and the sealing member 116 is used to abut against the side wall of the first mounting groove 113A. The sealing member 116 can increase the friction between the blocking member 114 and the side wall of the first mounting groove 113A. When the blocking member 114 is not in contact with the battery, the friction can be balanced with the gravity of the blocking member 114 and the thrust of the elastic member 115, so that the blocking member 114 is fixed on the main shaft 113, reducing the risk of the blocking member 114 falling off the main shaft 113, thereby improving the connection stability of the blocking member 114 and the main shaft 113. In addition, the blocking member 114 is fixed to the main shaft 113 by the sealing member 116, which is conducive to simplifying the structure of the main shaft 113 and the blocking member 114, thereby reducing the cost of the main shaft 113 and the blocking member 114.

[0089] Among them, the seal 116 can be directly put on the outside of the sealing member 114, or a second mounting groove is set on the surface of the sealing member 114, a part of the seal 116 is embedded in the second mounting groove, and the other part of the seal 116 extends out of the second mounting groove to abut against the side wall of the first mounting groove 113A. The provision of the second mounting groove can improve the connection stability between the seal 116 and the sealing member 114, and thereby improve the connection stability between the sealing member 114 and the main shaft 113.

[0090] In any of the above embodiments, Figure 7 As shown, the wiping tool also includes a first pulley 7, which is in contact with the first transmission belt 2, and the first pulley 7 is used to tighten the first transmission belt 2 between the first driving member 3 and the rotating shaft assembly 1; and / or, the wiping tool also includes a second pulley 8, which is in contact with the second transmission belt 4, and the second pulley 8 is used to tighten the second transmission belt 4 between the second driving member 5 and the rotating shaft assembly 1.

[0091] In this embodiment, the first transmission belt 2 and the second transmission belt 4 are tightened by the first pulley 7 and the second pulley 8, thereby reducing the accumulation of the first transmission belt 2 between the first driving member 3 and the rotating shaft assembly 1 and the accumulation of the second transmission belt 4 between the second driving member 5 and the rotating shaft assembly 1, thereby improving the accuracy and stability of the rotation of the rotating shaft 11 and the cleaning member 12, and further improving the working stability of the wiping tool.

[0092] In addition, the first rotating belt 13 and the second rotating belt 14 may be tightened by providing a third pulley and a fourth pulley to further improve the working stability of the wiping tool.

[0093] In summary, in one embodiment, the wiping steps of the wiping tool provided in this application are as follows:

[0094] Place the battery in the cleaning station;

[0095] The wiping tool is pressed down, and at least a portion of the blocking member 114 is inserted into the liquid filling port of the battery and blocks the liquid filling port, and the cleaning member 12 abuts against the surface of the battery;

[0096] The valve of the liquid storage tank is opened, and the cleaning liquid in the liquid storage tank enters the cleaning element 12 through the pipe 6 and the channel 112F;

[0097] The first driving member 3 rotates counterclockwise and drives the rotating shaft 11 and the cleaning member 12 to rotate counterclockwise through the first transmission belt 2 and the first rotating belt 13. At the same time, the second rotating belt 14 and the second transmission belt 4 are pulled by the rotating shaft 11, and the second driving member 5 rotates counterclockwise;

[0098] The first driving member 3 and the second driving member 5 stop rotating, and the valve of the liquid storage tank is closed;

[0099] The second driving member 5 rotates clockwise and drives the rotating shaft 11 and the cleaning member 12 to rotate clockwise through the second transmission belt 4 and the second rotating belt 14. At the same time, the first rotating belt 13 and the first transmission belt 2 are pulled by the rotating shaft 11, and the first driving member 3 rotates clockwise. At the same time, the valve of the liquid storage tank opens, and the cleaning liquid in the liquid storage tank enters the cleaning member 12 through the pipe 6 and the channel 112F.

[0100] The rotating shaft 11 and the cleaning member 12 are driven by the first driving member 3 and the second driving member 5 to rotate clockwise and counterclockwise alternately, and stop rotating after a preset number of cycles.

[0101] The battery is placed in the dry wiping station, and the rotating shaft 11 and the cleaning member 12 rotate clockwise and counterclockwise alternately under the drive of the first driving member 3 and the second driving member 5. There is no cleaning liquid in the cleaning member 12 at the dry wiping station. At this time, the cleaning member 12 is used to wipe the surface of the battery to complete the cleaning and drying steps of the battery surface.
