[0038] At present, from the development of market situation, the application of power battery is more and more extensive. The power battery is not only applied to the energy storage power supply system of water power, fire power, wind power and solar power station, but also widely applied to electric vehicles such as electric bicycles, electric motorcycles, electric vehicles and other electric vehicles, military equipment and aerospace and other fields. With the continuous expansion of the application field of power battery, the demand of its market is also increasing.

[0039] In the production process of soft package battery, the electrode assembly is generally packaged by aluminum plastic film, for example, the aluminum plastic film is sealed by heat sealing process to package the electrode assembly. Since the tab of the electrode assembly needs to protrude out of the aluminum plastic film, the heat sealing operation of the aluminum plastic film at the tab needs to be debugged in the heat sealing process to make the aluminum plastic film at the tab in a closed state. In the traditional machine debugging process, the heat sealing operation is directly performed on the tab of the electrode assembly to achieve the purpose of equipment debugging. However, this machine debugging method needs to invest a large number of electrode assemblies, which causes resource waste and increases the debugging cost.

[0040] Therefore, in order to solve the problems of resource waste and increased debugging cost in the traditional debugging process, the present application provides a machine debugging mechanism. In the machine debugging process, the elastic member is used to clamp the tab between the clamping member and the base, so that the tab and the base are regarded as a whole, so that the tab can be subjected to corresponding debugging operation. Since the tab is elastically clamped between the clamping member and the base, different tabs can be replaced to complete multiple machine debugging operations, thereby achieving the purpose of effective machine debugging. At the same time, when different tabs are replaced, the base can be recycled, thereby effectively reducing the waste of materials and reducing the debugging cost.

[0041] The electrode assembly refers to a component in which an electrochemical reaction occurs in a battery monomer. The electrode assembly is mainly formed by winding or stacking a positive electrode sheet and a negative electrode sheet, and a separator is usually arranged between the positive electrode sheet and the negative electrode sheet. The positive electrode sheet and the negative electrode sheet have a part of active material, which constitutes the main body of the electrode assembly, and the parts of the positive electrode sheet and the negative electrode sheet without active material each constitute a tab. The positive tab and the negative tab can be located at one end of the main body or at two ends of the main body respectively. In the charging and discharging process of the battery, the positive active material and the negative active material react with the electrolyte, and the tab is connected to the electrode terminal to form a current loop.

[0042] The adjusting mechanism provided by the application can be used not only for adjusting and sealing the tab, but also for adjusting and debugging devices at other parts of the battery, and of course, can also be used for adjusting and debugging devices of other products.

[0043] According to some embodiments of the application, referring to FIG. 1 and FIG. 2, the application provides an adjusting mechanism 100, which comprises a base body 10 and a clamping assembly 20. The clamping assembly 20 comprises a clamping piece 21 and an elastic piece 24. The clamping piece 21 is movably arranged on the base body 10, and the elastic piece 24 is arranged between the base body 10 and the clamping piece 21, and is used to drive the clamping piece 21 and the base body 10 to clamp the adjusting component 200.

[0044] The base body 10 refers to a structure cooperating with the adjusting component 200 to form a complete object to be adjusted, which provides a support basis for the adjusting operation of the adjusting component 200. The adjusting component 200 refers to an important part that is mainly concerned and adjusted during the adjusting process. Taking the packaging of the electrode assembly as an example, in the adjusting of the packaging, since the tab needs to be extended out of the aluminum plastic film, the heat sealing of the aluminum plastic film at the tab needs to be additionally concerned and adjusted. At this time, the adjusting component 200 is the tab, and the base body 10 can be the part of the electrode assembly except the tab. In this way, during the adjusting process, multiple individual tabs can be sequentially matched on the base body 10 for adjustment.

[0045] Of course, in order to further reduce the debugging cost, the base body 10 can also be a model of the part of the electrode assembly except the tab, which cooperates with the tab to form a false battery structure, such as: the base body 10 can be but is not limited to a plastic plate or a metal plate similar in shape and size to the electrode assembly. It should be noted that the tab is a real component on the electrode assembly.

[0046] During the adjusting process, the clamping piece 21 cooperates with the base body 10 under the elastic force of the elastic piece 24 to clamp the adjusting component 200, so that the base body 10 and the adjusting component 200 form a complete structure. After the adjusting operation is completed, the adjusting component 200 can be pulled out from between the clamping piece 21 and the base body 10, and another adjusting component 200 can be clamped between the clamping piece 21 and the base body 10 again, so as to realize quick plugging and unplugging, save time, and can be recycled.

[0047] The clamping piece 21 can be moved on the base body 10 in various ways, such as: the clamping piece 21 rotates on the base body 10 to clamp the adjusting component 200 in a rotating manner; or the clamping piece 21 can move on the base body 10 in a direction of approaching or moving away from the base body 10 to clamp or release the adjusting component 200, etc.

[0048] Meanwhile, the clamping force of the clamping member 21 on the tuning component 200 can be derived from the pushing force of the elastic member 24, i.e. the elastic member 24 is in a compressed state; or can be derived from the pulling force of the elastic member 24, i.e. the elastic member 24 is in a stretched state; or of course, can be derived from the torsion of the elastic member 24. The elastic member 24 can be, but is not limited to, a spring, elastic rubber, a torsion spring, an elastic metal sheet, etc.

[0049] In this way, by replacing different tuning components 200, multiple tuning operations can be completed, and the effective tuning purpose can be achieved. Meanwhile, when replacing different tuning components 200, the base body 10 can always be recycled, effectively reducing the waste of materials and reducing the debugging cost.

[0050] According to some embodiments of the present application, referring to FIGS. 2 and 3, the first surface 17 of the base body 10 along the thickness direction X is provided with a mounting groove 11, and an end surface along the first direction Y is provided with a socket 12 for inserting the tuning component 200 into the mounting groove 11, and the clamping member 21 is movably arranged in the mounting groove 11 to abut the tuning component 200 against the bottom wall 111 of the mounting groove 11; wherein the first direction Y intersects the thickness direction X.

[0051] The mounting groove 11 refers to a concave structure concavely formed on the first surface 17 along the thickness direction X, which includes a slot 113 on the first surface 17, a bottom wall 111 corresponding to the slot 113, and a side wall 112 surrounding the slot 113 and the bottom wall 111. For details, please refer to FIG. 3. The shape of the mounting groove 11 can have various designs, such as: the shape of the slot 113 of the mounting groove 11 can be, but is not limited to, square, circular, oval, etc. The slot 113 on the first surface 17 can extend to the socket 12 along the first direction Y; or can not extend to the socket 12, i.e. there is a partition structure between the slot 113 and the socket 12.

[0052] The socket 12 is located on an end surface of the base body 10, which is in communication with the mounting groove 11. In this way, when assembling, the tuning component 200 can be inserted into the socket 12 and extended into the mounting groove 11, so as to be clamped between the clamping member 21 and the base body 10. The size and shape of the socket 12 can be determined according to the size and shape of the tuning component 200, such as: when the tuning component 200 is a tab, the shape of the socket 12 can be designed as a square.

[0053] In this way, by introducing the socket 12 and the mounting groove 11, not only the installation of the clamping assembly 20 on the base body 10 is facilitated, and the overall thickness of the tuning mechanism 100 is reduced; but also the tuning component 200 can be stably and quickly inserted between the clamping member 21 and the base body 10, improving the assembly efficiency.

[0054] According to some embodiments of the present application, referring to FIGS. 4 and 5, the clamping member 21 is configured to move along the thickness direction X of the base 10 and abut against the bottom wall 111 of the mounting groove 11 under the action of the elastic member 24.

[0055] The clamping member 21 is movable up and down along the thickness direction X in the mounting groove 11 to clamp or release the tuning component 200. During tuning, the tuning component 200 can be forcibly inserted between the clamping member 21 and the bottom wall 111 of the mounting groove 11, or the clamping member 21 can be first separated from the bottom wall 111 of the mounting groove 11 against the elastic force, and then the tuning component 200 is inserted between the clamping member 21 and the bottom wall 111 of the mounting groove 11.

[0056] In this way, the clamping member 21 is designed to be movable up and down, which facilitates quick clamping of the tuning component 200 between the clamping member 21 and the bottom wall 111 of the mounting groove 11, thereby improving the tuning efficiency.

[0057] According to some embodiments of the present application, referring to FIG. 5, the second surface 18 of the base 10 opposite to the first surface 17 is provided with an opening 13 communicating with the mounting groove 11, and the clamping member 21 is provided with a pressing portion 211 protruding at least partially into the opening 13.

[0058] The first surface 17 and the second surface 18 are respectively two surfaces of the base 10 along the thickness direction X thereof, the mounting groove 11 is formed on the first surface 17 and extends along the thickness direction X to a certain depth, and forms a groove opening 113 on the first surface 17. The opening 13 is formed on the second surface 18 and communicates with the mounting groove 11. Since the tuning component 200 needs to be clamped on the bottom wall 111 of the mounting groove 11, the area of the opening 13 should be smaller than the area of the groove opening 113 of the mounting groove 11.

[0059] When the clamping member 21 abuts against the bottom wall 111 of the mounting groove 11 under the action of the elastic member 24, the pressing portion 211 protrudes at least partially into the opening 13. In this way, during tuning, the clamping member 21 can be separated from the bottom wall 111 of the mounting groove 11 by driving the pressing portion 211. In this way, the tuning component 200 with weak structural strength does not need to be forcibly inserted between the clamping member 21 and the bottom wall 111 of the mounting groove 11.

[0060] In this way, the opening 13 is provided on the second surface 18, which facilitates operation of the pressing portion 211 to separate the clamping member 21 from the bottom wall 111 of the mounting groove 11, and facilitates clamping of the tuning component 200 between the clamping member 21 and the bottom wall 111 of the mounting groove 11.

[0061] According to some embodiments of the present application, referring to FIGS. 5 and 6, the opening 13 is divided into the abutting portion 16 close to the insertion hole 12 on the base 10, and the abutting portion 16 is between the clamping member 21 and the side of the mounting groove 11.

[0062] After the opening 13 is formed on the second surface 18, the abutting portion 16 is formed on the side of the opening 13 along the first direction Y and close to the insertion hole 12, and the side of the abutting portion 16 facing the mounting groove 11 is part of the bottom wall 111 of the mounting groove 11. In this way, when the tuning component 200 is inserted into the mounting groove 11, the clamping member 21 clamps the tuning component 200 on the abutting portion 16 under the action of the elastic member 24.

[0063] In this way, the tuning component 200 is stably clamped by the abutting portion 16 and the clamping member 21, which facilitates stable and effective debugging operation.

[0064] According to some embodiments of the present application, referring to FIG. 2, the tuning mechanism 100 further comprises a support seat 22, which is arranged on the first surface 17 and covers the slot opening 113 of the mounting groove 11, and the elastic member 24 abuts between the clamping member 21 and the support seat 22.

[0065] The support seat 22 refers to a structure for supporting the installation of the clamping member 21 in the mounting groove 11, which can cover part of the slot opening 113 of the mounting groove 11, or can cover all of the slot opening 113 of the mounting groove 11. When the support seat 22 covers the slot opening 113 of the mounting groove 11, the clamping member 21 can be supported on the support seat 22 by the elastic member 24, so that the side of the clamping member 21 away from the elastic member 24 abuts on the bottom wall 111 of the mounting groove 11.

[0066] The support seat 22 can be fixed on the first surface 17 in various ways, such as, but not limited to, bolt connection, clamping, riveting, welding, and bonding. Meanwhile, the support seat 22 can have various shapes, such as a plate structure or a strip structure.

[0067] In this way, the mounting seat is introduced to facilitate the stable installation of the clamping member 21 in the mounting groove 11, so as to achieve the stable clamping of the tuning component 200.

[0068] According to some embodiments of the present application, referring to FIGS. 5 and 6, the side of the clamping member 21 facing the support seat 22 is provided with a fixing groove 214, and one end of the elastic member 24 abuts on the groove wall of the fixing groove 214.

[0069] The fixed groove 214 refers to a structure recessed inward on the clamping piece 21, which can accommodate one end of the elastic piece 24, so that the elastic piece 24 will not be disconnected from the clamping piece 21 to cause structural instability when it is elastically deformed. The shape of the fixed groove 214 can be various, such as a square groove, a circular groove, etc. In some examples, the clamping piece 21 includes a first component 212 and a second component 213 arranged at intervals, and the pressing part 211 is connected to the first component 212 and the second component 213 and forms a fixed groove 214 between the first component 212 and the second component 213. The first component 212 is close to the socket 12 relative to the second component 213, and the first component 212 cooperates with the bottom wall 111 of the mounting groove 11 to clamp the adjusting component 200.

[0070] The number of fixed grooves 214 can be one or multiple. When the number of fixed grooves 214 is multiple, the number of elastic pieces 24 can also be multiple, and each fixed groove 214 can abut at least one elastic piece 24.

[0071] In this way, the fixed groove 214 allows the elastic piece 24 to stably abut between the clamping piece 21 and the support seat 22, reduces the probability of structural instability caused by elastic deformation, and improves the stability of the structure.

[0072] According to some embodiments of the present application, referring to FIGS. 5 and 6, the first surface 17 is provided with a recess 14 arranged on at least one side of the mounting groove 11, and the support seat 22 is arranged on the inner wall of the recess 14.

[0073] The recess 14 is arranged on at least one side of the mounting groove 11, so that the support seat 22 is fixed on the first surface 17 while covering the slot opening 113 of the mounting groove 11. The number of recesses 14 can be one or multiple. When the number of recesses 14 is multiple, two recesses 14 can be respectively located on both sides of the mounting groove 11 along the second direction Z, the first direction Y, the second direction Z and the thickness direction X intersect with each other, and the three are not coplanar; or, two recesses 14 can also be respectively located on both sides of the mounting groove 11 along the first direction Y, at this time, the slot opening 113 of the mounting groove 11 does not extend to the socket 12, that is, there is a partition structure between the slot opening 113 and the socket 12, and one of the recesses 14 can be arranged on the partition structure. Of course, the recess 14 can also be arranged on four sides or three different sides of the mounting groove 11, so that the four sides or three sides of the support seat 22 are fixed.

[0074] In some examples, in order to facilitate the fixation of the support seat 22 and reduce structural interference, each recess 14 is in communication with the mounting groove 11. In addition, the support seat 22 can also be provided with a boss 221 fixed in the recess 14. The fixing mode of the boss 221 in the recess 14 can be, but is not limited to, bolt connection, clamping, riveting, welding, bonding, etc.

[0075] In this way, the recess 14 is arranged to stably fix the support base 22 to one side of the mounting groove 11, so that the clamping member 21 stably clamps the tuning component 200 to the bottom wall 111 of the mounting groove 11.

[0076] According to some embodiments of the present application, as shown in FIGS. 7 and 8, the clamping member 21 is rotatably connected in the mounting groove 11, and the elastic member 24 is connected between the clamping member 21 and the bottom wall 111 of the mounting groove 11, so that the one end of the clamping member 21 is used to clamp the tuning component 200 between the clamping member 21 and the bottom wall 111 of the mounting groove 11.

[0077] The clamping member 21 can be rotatably connected in the mounting groove 11 in various ways, such as: a protruding structure is arranged on the clamping member 21, and a shaft hole structure is arranged on the side wall 112 of the mounting groove 11; or a shaft structure is rotatably arranged on the side wall 112 of the mounting groove 11, and the clamping member 21 is connected to the shaft structure.

[0078] The one end of the clamping member 21 can abut against the bottom wall 111 of the mounting groove 11 under the action of the elastic member 24, or can not abut against the bottom wall 111 of the mounting groove 11, but the gap between the one end of the clamping member 21 and the bottom wall 111 of the mounting groove 11 should be smaller than the thickness of the tuning component 200, so that the clamping member 21 can clamp the tuning component 200. The elastic member 24 can be a spring or a torsion spring. When the elastic member 24 is a spring, it can pull the one end of the clamping member 21 to abut against the bottom wall 111 of the mounting groove 11 by elastic tension, or can push the one end of the clamping member 21 to abut against the bottom wall 111 of the mounting groove 11 by elastic thrust.

[0079] In this way, the clamping member 21 is designed as a rotatable structure, so that the clamping member 21 stably clamps the tuning component 200 to the bottom wall 111 of the mounting groove 11 in a rotating manner.

[0080] According to some embodiments of the present application, as shown in FIG. 8, the elastic member 24 is a torsion spring, and the tuning mechanism 100 further comprises a rotating shaft 23. The rotating shaft 23 is arranged on the side wall 112 of the mounting groove 11 located on both sides of the socket 12, the clamping member 21 is rotatably connected to the rotating shaft 23, the torsion spring is sleeved on the rotating shaft 23, one end of the torsion spring abuts against the clamping member 21, and the other end of the torsion spring abuts against the bottom wall 111 of the mounting groove 11.

[0081] The one end of the clamping member 21 abuts against the bottom wall 111 of the mounting groove 11 under the torsion of the torsion spring. When the tuning component 200 is placed between the clamping member 21 and the bottom wall 111 of the mounting groove 11, the clamping member 21 tightly presses the tuning component 200 to the bottom wall 111 of the mounting groove 11 under the torsion of the torsion spring, so as to achieve effective clamping. The number of the torsion springs can be one or more. When the number of the torsion springs is more than one, at least part of the torsion springs are sleeved on the rotating shaft 23, and one end of each of the torsion springs abuts against the clamping member 21.

[0082] In this way, the introduction of the rotating shaft 23 and the torsion spring enables the clamping member 21 to be stably and effectively clamped in the mounting groove 11, thereby facilitating the stability of the tuning operation.

[0083] According to some embodiments of the present application, referring to FIG. 8, the clamping member 21 comprises a sleeve portion 215 and clamping portions 216 and force applying portions 217 respectively arranged on both sides of the sleeve portion 215, the clamping portions 216 are close to the socket 12 relative to the force applying portions 217, the sleeve portion 215 is sleeved on the rotating shaft 23, one end of the torsion spring abuts against the force applying portions 217, and the other end abuts against the bottom wall 111 of the mounting groove 11.

[0084] The sleeve portion 215 refers to a structure that can be sleeved on the rotating shaft 23, and the inside is a hollow structure. The clamping portions 216 and the force applying portions 217 are respectively arranged on opposite sides of the sleeve portion 215, so that the clamping portions 216 and the force applying portions 217 can be formed as a structure similar to a seesaw with the sleeve portion 215 as the fulcrum. For example, under the action of the torsion spring, the force applying portions 217 are lifted, and the clamping portions 216 are pressed down, so that the tuning component 200 can be clamped on the bottom wall 111 of the mounting groove 11.

[0085] The connection mode between the clamping portions 216, the sleeve portion 215 and the force applying portions 217 can be various, such as bolt connection, welding, riveting, etc.; of course, it can also be an integrated molding mode. In some examples, the clamping portions 216, the sleeve portion 215 and the force applying portions 217 are integrated structures.

[0086] In order to improve the clamping effect, one end of the clamping portion 216 can be designed as a bending structure 219, and one end of the bending structure 219 is a sharp end. In addition, in order to facilitate the installation of the torsion spring, a notch 218 can be provided on the sleeve portion 215, the torsion spring is installed in the notch 218, and the sleeve portion 215 and the sleeve portion 215 are sleeved on the rotating shaft 23. At the same time, the two ends of the torsion spring respectively pass out of the sleeve portion 215, and abut against the bottom wall 111 of the mounting groove 11 and the force applying portions 217.

[0087] In this way, the clamping member 21 is designed as the clamping portions 216, the sleeve portion 215 and the force applying portions 217, which facilitates the elastic member 24 to apply force to the clamping member 21, so that the clamping member 21 can stably clamp the tuning component 200 with the bottom wall 111 of the mounting groove 11.

[0088] According to some embodiments of the present application, referring to FIG. 8, the bottom wall 111 of the mounting groove 11 is provided with a limiting portion 15, and one end of the torsion spring abuts against one side of the limiting portion 15 away from the socket 12.

[0089] The limiting portion 15 refers to a structure that can abut against one end of the torsion spring, so that the torsion of the other end of the torsion spring acts on the clamping member 21, which can be designed as a block structure or a strip structure.

[0090] In this way, the limiting portion 15 is introduced, and the one end of the elastic member 24 is stably abutted on the bottom of the mounting groove 11.

[0091] According to some embodiments of the present application, referring to FIG. 8, the number of the mounting grooves 11 is two or more, and at least part of the mounting grooves 11 are sequentially arranged along the second direction Z, and each of the mounting grooves 11 is configured with the clamping assembly 20; wherein the first direction Y, the second direction Z and the thickness direction X are orthogonal to each other, and the three are not coplanar.

[0092] The number of the mounting grooves 11 is designed to be two or more, which can simultaneously satisfy the debugging operation of multiple machine adjusting components 200. Taking the packaging of the electrode assembly as an example, the positive and negative tabs can be clamped in different mounting grooves 11 respectively, so as to simultaneously perform the heat sealing debugging operation.

[0093] The number of the sockets 12 can be one or multiple. When the number of the sockets 12 is one, the same socket 12 can be in communication with multiple mounting grooves 11; when the number of the sockets 12 is multiple, the sockets 12 can be one-to-one configured with the mounting grooves 11.

[0094] When each clamping piece 21 is supported on the support seat 22 through the elastic member 24, the number of the support seats 22 can be one or multiple. If the number of the support seats 22 is one, each clamping piece 21 shares one support seat 22, and at this time the support seat 22 covers the slot opening 113 of each mounting groove 11. If the number of the support seats 22 is multiple, each clamping piece 21 can be supported on the corresponding support seat 22 through the elastic member 24.

[0095] When each clamping piece 21 is rotatably connected to the rotating shaft 23, the number of the rotating shafts 23 can also be one or multiple. If the number of the rotating shafts 23 is one, each clamping piece 21 shares one rotating shaft 23, and at this time the rotating shaft 23 penetrates each mounting groove 11. If the number of the rotating shafts 23 is multiple, each clamping piece 21 can be rotatably connected to the corresponding rotating shaft 23.

[0096] In this way, two or more mounting grooves 11 are introduced, which facilitates the debugging operation of multiple machine adjusting components 200 at the same time, and improves the machine adjusting efficiency.
