DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, 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 efforts are within the scope of protection of this application.

[0041] In this application, the terms "upper" and "upper" and other terms indicating positions or locations are based on the positions or locations shown in the accompanying drawings. These terms are primarily intended to better describe this application and its embodiments and are not intended to limit the devices, elements, or components indicated to having a specific position, or to being constructed or operated in a specific position.

[0042] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0043] Furthermore, the terms "disposed" and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0044] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0045] Cell strip winding technology, a core process in lithium-ion battery production, combines positive and negative electrode materials with separator materials through winding to form a strip structure. This technology not only ensures excellent energy density but also effectively reduces the battery's internal resistance. These two advantages make lithium-ion batteries an ideal choice for applications such as electric vehicles and large-scale energy storage systems.

[0046] See also Figure 1 When the battery cell material strip is wound, the battery cell material strip may be offset or skewed, resulting in unsatisfactory material strip feeding and poor battery cell winding quality, resulting in waste of battery cell resources and low battery cell winding efficiency.

[0047] In order to overcome these problems, a feed correction component can be used. The feed correction component is arranged downstream of the insert mechanism. The insert mechanism is used to feed the material strip into the feed correction component. The feed correction component clamps the material strip and transfers the material strip to the winding needle. When the head of the material strip deviates, the feed correction component corrects it. The feed correction component can correct the head of the material strip, thereby improving the winding accuracy of the material strip, reducing the generation of waste, and improving the winding efficiency.

[0048] However, the feed deflection correction component of the above-mentioned feed deflection correction component has a small correction range. When the deviation of the material strip head is large, the feed deflection correction component cannot reliably correct it, thereby affecting the material strip winding accuracy.

[0049] Based on this, on the first aspect, the embodiment of the present application discloses an inserting mechanism, which can further improve the winding accuracy of the material strip, improve the winding efficiency of the material strip, improve the winding quality of the battery cell, and reduce the waste of the material strip.

[0050] The technical solution of the present application will be further described below with reference to the embodiments and drawings.

[0051] See also Figure 1 and Figure 2 , Figure 2 This is a structural diagram of an inserting mechanism disclosed in an embodiment of the present application.

[0052] The embodiment of the present application discloses a tab insertion mechanism 100 for a battery cell winding machine 200. The battery cell winding machine 200 includes a bottom plate 11. The tab insertion mechanism 100 includes:

[0053] The sheet feeding assembly 12 is rotatably connected to the base plate 11 via a rotating shaft 14. The sheet feeding assembly 12 is capable of conveying the material strip 10 along the feeding direction of the material strip 10. The rotating shaft 14 is perpendicular to the feeding direction of the material strip 10 and parallel to the base plate 11. The deflection correction assembly 13 is in transmission connection with the sheet feeding assembly 12 and is capable of driving the sheet feeding assembly 12 to rotate about the axis of the rotating shaft 14. Specifically, when the material strip 10 is being fed, if the head of the material strip 10 deviates, when the next material strip 10 is wound, the deflection correction assembly 13 drives the sheet feeding assembly 12 to rotate about the axis of the rotating shaft 14, i.e., a direction perpendicular to the feeding direction of the material strip 10 and parallel to the base plate 11, thereby adjusting the position of the material strip 10 clamped by the sheet feeding assembly 12, thereby adjusting the feeding position of the head of the material strip 10.

[0054] Among them, the correction component 13 can drive the feeding component 12 to make adjustments, ensuring that the feeding direction of the material belt 10 is always accurate, thereby improving the feeding accuracy of the material belt 10 during the production process; the correction component 13 reduces the waste of the material belt 10 caused by the deviation of the material belt 10, reduces the production cost, and improves the material utilization rate; and the automated correction reduces the need for operators to directly contact the high-speed running insertion mechanism 100, reducing the safety risks in the production process.

[0055] See also Figure 2 In some embodiments, the sheet feeding assembly 12 includes a support plate 121 and a transmission member 122. The support plate 121 is rotatably connected to the base plate 11. The correction assembly 13 is transmission-connected to the support plate 121. The transmission member 122 is arranged on the support plate 121. The transmission member 122 is used to convey the material belt 10 along the feeding direction of the material belt 10.

[0056] Specifically, the support plate 121 is connected to the base plate 11 through rotation, so that the entire correction component 13 can be adjusted according to the feeding situation of the material belt 10, so that the insert mechanism 100 can effectively respond to the dynamic changes of the material belt 10 during the transmission process, so that the material belt 10 can be in an ideal position; the transmission connection between the correction component 13 and the support plate 121 makes the correction action more accurate, and can respond to changes in the position of the material belt 10, and adjust the position of the transmission member 122 in time, so as to realize the control of the feeding direction of the material belt 10, reduce offset and deviation, and improve the stability and efficiency of the production process; the transmission member 122 is directly arranged on the support plate 121, and is closely linked with the correction component 13 and the support plate 121, which reduces energy loss and response delay in the transmission process, and improves the efficiency and speed of the transmission of the material belt 10.

[0057] In order to realize that the support plate 121 can rotate relative to the bottom plate 11, please refer to Figure 2 In one embodiment, a mounting hole 111A is provided on the base plate 11, and the support plate 121 is rotatably installed in the mounting hole 111A through the rotating shaft 14; specifically, the above-mentioned support plate 121 also includes a first side 1211 and a second side 1212, and the first side 1211 and the second side 1212 are arranged along the axial direction of the rotating shaft 14, and a first protrusion 1214 is provided on the first side 1211, and a second protrusion 1215 is provided on the second side 1212. The first protrusion 1214 and the second protrusion 1215 protrude from the first side 1211 and the second side 1212 along the axial direction of the rotating shaft 14, and the rotating shaft 14 is set on the first protrusion 1214 and the second protrusion 1215.

[0058] First, the shape of the mounting hole 111A corresponds to the shape of the support plate 121. By opening the mounting hole 111A on the base plate 11 and rotating the rotating shaft 14 in the mounting hole 111A, the support plate 121 can be rotated relative to the base plate 11. The installation method of the rotating shaft 14 simplifies the installation and disassembly process of the support plate 121, facilitates the assembly, disassembly and maintenance of the insert mechanism 100, and reduces maintenance costs and time consumption. Through the connection of the rotating shaft 14, the external force can be evenly distributed to the support plate 121 and the base plate 11, avoiding local excessive force and structural damage, thereby extending the service life of the insert mechanism 100. Secondly, the arrangement of the first protrusion 1214 and the second protrusion 1215 of the support plate 121 can enhance the support The rigidity of the support plate 121 reduces deformation when subjected to external force or weight. At the same time, by arranging the rotating shaft 14 on the protrusion, the force can be dispersed more evenly, thereby improving the stability and carrying capacity of the entire structure. The design of the protrusion makes the force transmission path more direct and effective, reducing the loss of force during the transmission process. At the same time, this design can avoid applying force directly to the side, preventing the side from being damaged due to excessive local force. Arranging the rotating shaft 14 on the first protrusion 1214 and the second protrusion 1215 can ensure the precise positioning of the rotating shaft 14, avoiding poor rotation or wear due to inaccurate installation position. At the same time, the protrusion structure can increase the support area of ​​the rotating shaft 14, thereby improving the stability and smoothness of the rotation process.

[0059] See also Figure 2 In order to realize the rotation of the above-mentioned support plate 121, in some embodiments, the correction component 13 includes a driving member 131, which is arranged on the base plate 11, and the driving end 131A of the driving member 131 is connected to the support plate 121, and the driving end 131A can reciprocate in a direction perpendicular to the base plate 11. Specifically, the above-mentioned driving end 131A includes a driving shaft 1311 and a connecting block 1312, and the driving shaft 1311 is rotatably connected to the connecting block 1312. The driving shaft 1311 can reciprocate in a direction perpendicular to the base plate 11, and the connecting block 1312 is connected to the support plate 121.

[0060] On the one hand, the driving end 131A of the driving member 131 is connected to the support plate 121 and can reciprocate in a direction perpendicular to the base plate 11 to provide a driving force for correcting the deviation of the support plate 121, thereby realizing the rotation of the support plate 121 along the axial direction of the rotating shaft 14; on the other hand, the driving end 131A includes a driving shaft 1311 and a connecting block 1312. The matching arrangement of the driving shaft 1311 and the connecting block 1312 enables the driving member 131 to provide a stable driving force, and the driving member 131 will not rotate with the support plate 121 due to the rotation of the support plate 121, thereby affecting the stability of the driving member 131; and the design of the rotating connection allows the connecting block 1312 to automatically adjust its position according to actual needs, thereby reducing stress concentration and mechanical wear caused by the fixed connection, and extending the service life of the insert mechanism 100; the vertical movement design of the driving shaft 1311 can effectively reduce the lateral force, avoid shaking or offset of the support plate 121 during movement, and improve the overall stability and reliability of the insert mechanism 100.

[0061] See also Figure 3 and Figure 4 , Figure 3 for Figure 2 Another structural diagram of the inserting mechanism 100 is shown in FIG. Figure 4 for Figure 3 Another schematic diagram of the inserting mechanism 100 (the base plate 11, the sheet feeding assembly 12 and the cutting assembly 15 are omitted). In another embodiment, a hinged seat 112 is provided on the base plate 11, and the support plate 121 is rotatably connected to the hinged seat 112 through a rotating shaft 14. The support plate 121 is spaced apart from the base plate 11 so that the support plate 121 has rotation space. Specifically, the hinged seat 112 and the support plate 121 are arranged on both sides of the base plate 11 along the thickness direction of the base plate 11, and the hinged seat 112 is connected to the base plate 11. The support plate 121 also includes an extension portion 1213, which passes through the base plate 11 and is rotatably connected to the hinged seat 112 through the rotating shaft 14.

[0062] First, the support plate 121 and the base plate 11 are spaced apart by the hinge seat 112, which ensures that the support plate 121 does not interfere with the base plate 11 or other components when rotating, provides sufficient space for the rotation of the support plate 121, optimizes the internal space layout of the insert mechanism 100, improves space utilization efficiency, reduces structural instability factors caused by direct contact, and improves the rigidity and external force resistance of the overall structure; secondly, the extension 1213 of the support plate 121 passes through the base plate 11 and is connected to the hinge seat 112 by the rotating shaft 14, which can more effectively disperse and transmit force, avoid local excessive force, and improve the stability and impact resistance of the insert mechanism 100 when bearing loads. The hinge seat 112 and the support plate 121 are arranged on both sides of the base plate 11 along the thickness direction of the base plate 11, which makes full use of the space in the thickness direction of the base plate 11, reduces the horizontal usage area of ​​the insert mechanism 100, and improves space utilization.

[0063] It should be noted that the number of the above-mentioned articulated seats 112 can be one or more. Taking two as an example, there are two articulated seats 112, and extension portions 1213 are respectively provided on the opposite sides of the support plate 121. The two extension portions 1213 are respectively rotatably connected to the two articulated seats 112 through the rotating shaft 14. By providing extension portions 1213 on the opposite sides of the support plate 121 and connecting them to the two articulated seats 112, a stable support structure is formed. This symmetrical layout can evenly distribute the load, improve the stability and balance of the structure, reduce shaking and offset, and improve the durability and reliability of the insert mechanism 100. The embodiment of the present application does not limit the number of articulated seats 112.

[0064] See also Figure 3 and Figure 4 In some embodiments, the correction component 13 includes a driving member 131, which is arranged on the same side as the hinge seat 112. The driving end 131A of the driving member 131 passes through the base plate 11 and is connected to the support plate 121. The driving end 131A can reciprocate in a direction perpendicular to the base plate 11.

[0065] Among them, the driving end 131A is directly connected to the support plate 121 and can reciprocate in a direction perpendicular to the base plate 11, thereby realizing the control of the position of the support plate 121, optimizing the force transmission path, reducing energy loss and deformation during the force transmission process, and improving the efficiency and accuracy of force transmission; the driving member 131 and the articulated seat 112 are arranged on the same side, which simplifies the internal structure layout of the insert mechanism 100, reduces unnecessary complex connections, and reduces the design and manufacturing costs of the insert mechanism 100. The design of the driving member 131 and the articulated seat 112 on the same side reduces the horizontal space requirement of the insert mechanism 100 and improves the space utilization efficiency of the insert mechanism 100.

[0066] Exemplarily, the above-mentioned driving component 131 can adopt a combination of devices such as electric cylinders, motor screw nuts, etc. that can provide driving force. Taking the electric cylinder as an example, the electric cylinder can achieve micron-level positioning accuracy and is suitable for precision control application scenarios; the energy conversion efficiency of the electric cylinder is higher than that of the hydraulic and pneumatic systems, reducing energy waste; the operation of the electric cylinder is quieter, reducing interference with the surrounding environment. The embodiment of the present application does not limit the driving component.

[0067] For details, please refer to Figure 2 The transmission member 122 of the above two embodiments includes a driving wheel 1221, a driven wheel 1222 and a driving motor 1223. The material belt 10 is arranged between the driving wheel 1221 and the driven wheel 1222. The driving motor 1223 drives the driving wheel 1221 to rotate.

[0068] Among them, through the coordinated action of the driving wheel 1221, the driven wheel 1222 and the driving motor 1223, the stability and consistency of the material belt 10 during the transmission process are ensured, and the efficiency and reliability of the transmission of the material belt 10 are improved. The driving wheel 1221, the driven wheel 1222 and the driving motor 1223 have a simple structure and are easy to disassemble and maintain. Compared with the traditional material transmission method, the driving wheel 1221 and the driven wheel 1222 controlled by the driving motor 1223 can more effectively control energy consumption and reduce energy waste.

[0069] In order to further improve the winding quality of the strip 10, please refer to Figure 2 The inserting mechanism 100 also includes a cutting assembly 15, which is arranged on the support plate 121. The feeding assembly 12 and the cutting assembly 15 are arranged in sequence along the feeding direction of the material belt 10. The cutting assembly 15 can cut the material belt 10 transmitted by the feeding assembly 12.

[0070] First, the cutting assembly 15 is also installed on the support plate 121, so that the cutting assembly 15 swings with the support plate 121, so that the cutting position on the material strip 10 is perpendicular to the two end faces of the material strip 10, that is, in the width direction, thereby ensuring that each time the cutting assembly 15 performs a cutting operation, the cutting position relative to the material strip 10 is the same, ensuring the consistency and aesthetics of the material strip 10; secondly, the sheet feeding assembly 12 and the cutting assembly 15 are arranged on the same support plate 121, which simplifies the overall layout of the inserting mechanism 100, reduces the relative motion error between components, reduces the complexity of the inserting mechanism 100, and improves production efficiency and stability.

[0071] See also Figure 5 and Figure 6 , Figure 5 This is a structural diagram of a battery cell winding machine disclosed in an embodiment of the present application. Figure 6 for Figure 5Another structural schematic diagram of the battery cell winding machine (the inserting mechanism 100 is omitted) in the embodiment of the present application is a second aspect. A battery cell winding machine 200 is provided, comprising:

[0072] Bottom plate 11;

[0073] The winding assembly 21 is capable of winding the material strip 10 to form a battery core;

[0074] As with the inserting mechanism 100 described in the first aspect, the material strip 10 is wound on the winding assembly 21 after passing through the inserting mechanism 100 .

[0075] Specifically, the battery cell winding machine 200 also includes a feed-in deviation correction device 23 and a detection component 22. The feed-in deviation correction device 23 is arranged on the winding component 21 corresponding to the inserting mechanism 100. The feed-in deviation correction device 23 can correct the deviation of the material strip 10 in a direction perpendicular to the bottom plate 11. The detection component 22 is electrically connected to the inserting mechanism 100 and is used to detect the deviation of the material strip 10 in a direction perpendicular to the bottom plate 11. In order to ensure that the correction roller on the feed-in deviation correction device 23 is parallel to the winding needle 212, please refer to Figure 6 The above-mentioned winding assembly 21 includes a turret 211, a winding needle 212 and a turret bearing seat 213. The turret bearing seat 213 is arranged on the base plate 11. The turret 211 is rotated on the turret bearing seat 213. The winding needle 212 is arranged on the turret 211. The turret 211 can drive the winding needle 212 to rotate. The feed correction device 23 is arranged on the turret bearing seat 213.

[0076] Among them, the feeding correction device 23 and the winding needle 212 are both arranged on the turret bearing seat 213. On the one hand, the material belt has a hole on the bottom plate 11 for installing the turret bearing seat 213. If the feeding correction device 23 is installed near the turret bearing seat, since the hole for installing the turret bearing seat 213 is opened on the bottom plate 11, the installation accuracy of the feeding correction device 23 cannot be guaranteed. However, if the feeding correction device 23 is arranged on the turret bearing seat 213, the installation accuracy of the feeding correction device 23 can be guaranteed, thereby improving the operation of the battery cell winding machine 200. Stability and extended service life; on the other hand, the feed correction device 23 and the winding needle 212 are both arranged on the turret bearing seat 213, which can ensure the parallelism of the correction roller on the feed correction device 23 and the winding needle 212, and ensure that the feed correction device 23 can smoothly guide the material strip 10, and the winding needle 212 can complete the winding, which can improve production efficiency and product consistency, and can ensure that during the material transportation and processing process, the correction effect is more accurate and effective, thereby improving the overall processing quality and the operating stability of the battery cell winding machine 200.
