Description

Technical Field

[0001] This application relates to the field of electrode production equipment technology, and in particular to a clamping device and an electrode leading device for electrode leading. Background Technology

[0002] Electrodes are a crucial raw material for lithium battery production, and their quality and consistency directly affect battery performance and safety. In the electrode production line, electrode conveying is a critical step that directly impacts production efficiency and product quality. Currently, the most common electrode conveying method involves using the rotation of multiple rollers to move the electrodes forward. However, in the initial stage of conveying, the electrodes must first be wound onto the rollers before the machine can operate and the entire production line can run. This process of winding the electrodes onto the rollers is called "lead-in".

[0003] In related technologies, the common method of electrode drawing involves directly attaching the electrode sheet to the electrode drawing rod with adhesive tape. The electrode drawing rod then guides the electrode sheet onto the roller under traction. After the drawing process is complete, the adhesive tape is removed.

[0004] However, this method of applying adhesive requires operators to have certain skills and experience. The operation is complicated and time-consuming. The process of applying and removing adhesive can easily damage the electrode sheet. Furthermore, manual application of adhesive can easily result in uneven adhesive quality. During the traction process, the electrode sheet is prone to uneven stress and breakage, forcing the lead-in operation to be stopped. Utility Model Content

[0005] To solve or partially solve the problems existing in the related technologies, this application provides a clamping device and an electrode guiding device for electrode stripping, which can eliminate the need for adhesive application, reduce the complexity of the guiding operation, and avoid the inconsistency of manual adhesive application quality, so that the electrode strip is subjected to more uniform force during the traction process, effectively preventing the occurrence of electrode strip breakage.

[0006] The first aspect of this application provides a clamping device for electrode lead-in, comprising:

[0007] Base;

[0008] A fixing rod, which is fixed to the base;

[0009] A movable rod is detachably connected to the base parallel to the fixed rod, and a clamping gap is left between the movable rod and the fixed rod for the electrode to be guided to pass through;

[0010] A limiting mechanism is movably disposed at one end of the movable rod, the limiting mechanism moving in the axial direction of the movable rod; and, when the limiting mechanism moves toward the base, the limiting mechanism can be limited to the base to restrict the movable rod on the base; when the limiting mechanism moves away from the base, the limiting mechanism can be separated from the base to allow the movable rod to disengage from the base.

[0011] As an optional embodiment, the limiting mechanism includes a first limiting member, which is rotatably disposed at one end of the movable rod to move toward or away from the base.

[0012] As an optional embodiment, the limiting mechanism further includes a second limiting component, which is disposed opposite to the first limiting member on both sides of one end of the base. The second limiting component can move closer to or further away from the first limiting member under the rotation of the first limiting member, so as to clamp or release the base.

[0013] As an optional embodiment, one end of the base is provided with a first through hole, one end of the movable rod is movably disposed in the first through hole, and a limit hole is formed on the end face of the first through hole; the second limit component includes:

[0014] The second limiting member has a second through hole that is connected to the limiting hole.

[0015] The fastener passes through the second through hole and is inserted into the limiting hole; and the second limiting member can be inserted into or out of the first through hole under the rotation of the first limiting member.

[0016] As an optional embodiment, a push-in port communicating with the first through hole is also provided at the top of one end of the base. When the base is released, one end of the movable rod can enter or exit the first through hole through the push-in port.

[0017] As an optional embodiment, the base includes a fixed seat and a limiting seat arranged at relatively intervals, with both ends of the fixed rod and the movable rod respectively connected to the fixed seat and the limiting seat, and the limiting mechanism is disposed at the end of the movable rod near the limiting seat.

[0018] As an optional embodiment, the fixed base is provided with an insertion port through it, and the movable rod is provided with a plug at one end near the fixed base, the plug being inserted into the insertion port.

[0019] As an optional embodiment, the fixed base and the limiting base are provided with two mounting holes through each other, and the two ends of the fixed rod are respectively inserted into the two mounting holes; the clamping device also includes two fixing members, which are respectively disposed at the two ends of the fixed rod and respectively cooperate with the fixed base and the limiting base to limit the movement of the fixed rod.

[0020] As an optional embodiment, the first end of the electrode passes through the clamping gap around the outer periphery of the fixing rod and extends to the electrode itself to form an overlapping area.

[0021] A second aspect of this application provides an electrode guide device, including a guide seat and the aforementioned clamping device, wherein the clamping device is fixed on the guide seat and can move along the electrode guide direction under the traction of the guide seat to guide the electrode onto a plurality of rollers of a conveying device.

[0022] As an optional embodiment, the guide seat is a chain structure, and the base of the clamping device is provided with a connecting shaft, which is disposed through the shaft hole of a link of the chain structure.

[0023] The technical solution provided in this application may include the following beneficial effects:

[0024] When leading the electrode sheet, the limiting mechanism can first be moved away from the base, separating it from the base. Then, the movable rod is detached from the base, and the electrode sheet to be led is wound around the fixed rod. Next, the movable rod is installed on the base, and the limiting mechanism is moved closer to the base, limiting it and fixing the movable rod to the base. Finally, the lead-in clamping device can be pulled along the electrode sheet's leading direction to lead the electrode sheet onto multiple rollers of the conveyor, thus achieving electrode leading. Using the clamping device provided in this embodiment for electrode leading eliminates the need for adhesive, reduces the leading clamping steps, simplifies the leading process, and improves production efficiency. Furthermore, eliminating the use of adhesive tape reduces material consumption, lowers the probability of electrode damage, improves product yield, and further reduces production costs. During the lead-in process, the clamping device of this application embodiment is subjected to traction forces and clamping forces (including frictional forces between the electrode and the fixed rod and the movable rod) of opposite directions and equal magnitude. The greater the traction force, the greater the clamping force, which enables the clamping device to have a "self-tightening" function, ensuring that the clamping force is moderate and uniform during the lead-in process. This achieves dynamic adjustment of the clamping force of the clamping device, avoids breakage or deformation caused by uneven force on the electrode, and ensures the reliability and stability of the lead-in process.

[0036] Embodiments of this application will now be described in more detail with reference to the accompanying drawings. While embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.

These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0038] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and 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 application.

[0039] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to 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 application according to the specific circumstances.

[0040] In related technologies, see Figure 1 The common method of guiding the electrode 4' is to directly attach the electrode 4' to the guide rod 2' with tape 1'. The guide rod 2' guides the electrode 4' to the roller 3' under the traction action. After the guiding is completed, the tape 1' is removed.

[0041] However, this method of applying adhesive requires operators to have certain skills and experience. The operation is complicated and time-consuming. The process of applying and removing adhesive can easily damage the electrode sheet. Furthermore, manual application of adhesive can easily result in uneven adhesive quality. During the traction process, the electrode sheet is prone to uneven stress and breakage, forcing the lead-in operation to be stopped.

[0042] To address the aforementioned issues, this application provides a clamping device for electrode lead-in, which eliminates the need for adhesive application, reducing the complexity of the lead-in operation. It also avoids the inconsistencies in quality caused by manual adhesive application, resulting in more uniform force distribution on the electrode during traction and effectively preventing electrode breakage.

[0043] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0044] Figure 2 This is an exploded view of a clamping device for electrode lead-in shown in an embodiment of this application.

[0045] See Figure 2 This application provides a clamping device for electrode strip feeding, including a base 1, a fixed rod 2, a movable rod 3, and a limiting mechanism 5. The fixed rod 2 is fixed to the base 1, and the movable rod 3 is detachably connected to the base 1 parallel to the fixed rod 2, with a clamping gap between the movable rod 3 and the fixed rod 2 for the electrode strip 4 to be fed through. The limiting mechanism 5 is movably disposed at one end of the movable rod 3, and the direction of movement of the limiting mechanism 5 is along the axial direction of the movable rod 3. When the limiting mechanism 5 moves toward the base 1, it can limit the movable rod 3 to the base 1. When the limiting mechanism 5 moves away from the base 1, it can separate from the base 1, allowing the movable rod 3 to detach from the base 1.

[0046] In this embodiment, the base 1 can be fixed on the guide seat 7 of the guide device and move together with the guide seat 7 along the guide direction of the electrode 4. The fixed rod 2 can be fixed on the base 1 and cannot be removed. One end of the movable rod 3 can be detachably connected to the base 1 through the limiting mechanism 5. When clamping different electrodes 4, only the movable rod 3 needs to be removed and installed to clamp different electrodes 4.

[0047] When guiding the electrode sheet, the limiting mechanism 5 can be moved away from the base 1 first, separating the limiting mechanism 5 from the base 1; then the movable rod 3 can be removed from the base 1, and the electrode sheet 4 to be guided can be wound around the fixed rod 2; then the movable rod 3 can be installed on the base 1, and the limiting mechanism 5 can be moved closer to the base 1, limiting the limiting mechanism 5 to the base 1, fixing the movable rod 3 to the base 1; finally, the guiding seat 7 can be used to pull the clamping device along the guiding direction of the electrode sheet 4 to guide the electrode sheet 4 onto the multiple rollers 8 of the conveying device, thus realizing the guiding of the electrode sheet 4.

[0048] Using the clamping device provided in this application embodiment for electrode lead-ahead can eliminate the need for adhesive, reduce lead-ahead clamping steps, simplify the lead-ahead process, and improve production efficiency. Furthermore, eliminating the use of adhesive tape reduces material consumption, lowers the probability of electrode damage, improves product yield, and further reduces production costs. During the lead-ahead process, the clamping device in this application embodiment is subjected to opposing and equal traction and clamping forces (including friction between the electrode 4 and the fixed rod 2 and movable rod 3). The greater the traction force, the greater the clamping force, giving the clamping device a "self-tightening" function. This ensures that the clamping force is moderate and uniform during lead-ahead, enabling dynamic adjustment of the clamping force and preventing breakage or deformation of the electrode due to uneven force, thus ensuring the reliability and stability of the lead-ahead process.

[0049] As an optional embodiment, see Figure 2 and Figure 3 As shown, the limiting mechanism 5 includes a first limiting member 50, which is rotatably disposed at one end of the movable rod 3 so as to move toward or away from the base 1.

[0050] In this embodiment of the application, the first limiting member 50 is rotatably disposed at one end of the movable rod 3. When the first limiting member 50 rotates and moves toward the base 1, the first limiting member 50 can move to abut against the base 1 and limit the movable rod 3 on the base 1. When the first limiting member 50 rotates and moves away from the base 1, the first limiting member 50 can separate from the base 1 to allow the movable rod 3 to detach from the base 1.

[0051] In this embodiment, the first limiting member 50 can be a knurled nut, which is easier to tighten by hand than a regular nut, making it more convenient for workers to operate.

[0052] As a preferred embodiment, see Figure 2 and Figure 3 As shown, the limiting mechanism 5 also includes a second limiting component 51. The second limiting component 51 and the first limiting component 50 are respectively disposed on the two sides of one end of the base 1. The second limiting component 51 can move closer to or further away from the first limiting component 50 under the rotation of the first limiting component 50, so as to clamp or release the base 1.

[0053] In this embodiment, the second limiting component 51 can be disposed at one end of the movable rod 3, and is disposed opposite to the first limiting member 50 on both sides of one end of the base 1. That is, the first limiting member 50 and the second limiting component 51 are respectively disposed on both sides of one end of the base 1. When the first limiting member 50 rotates and moves toward the base 1, the second limiting component 51 can move closer to the first limiting member 50 under the rotational action of the first limiting member 50, until the first limiting member 50 and the second limiting component 51 clamp the base 1 to restrict the movable rod 3 on the base 1; when the first limiting member 50 rotates and moves away from the base 1, the second limiting component 51 can move away from the first limiting member 50 under the rotational action of the first limiting member 50, releasing the base 1 to allow the movable rod 3 to detach from the base 1. In this embodiment, the limiting cooperation between the second limiting component 51 and the first limiting member 50 can prevent the movable rod 3 from moving during the guiding process. In this embodiment of the application, the movement of the movable rod 3 during the guiding process is prevented by the limiting cooperation between the second limiting component 51 and the first limiting component 50.

[0054] As a preferred embodiment, see Figure 2 and Figure 3 As shown, one end of the base 1 is provided with a first through hole 10, and one end of the movable rod 3 is movably disposed in the first through hole 10, and the end face of the rod is provided with a limiting hole 30; the second limiting component 51 includes a second limiting member 510 and a fastener 512, the second limiting member 510 is provided with a second through hole 511, and the second through hole 511 is connected to the limiting hole 30; the fastener 512 passes through the second through hole 511 and is inserted into the limiting hole 30; and the second limiting member 510 can be inserted into or out of the first through hole 10 under the rotation of the first limiting member 50.

[0055] In this embodiment, the end face of the movable rod 3 is fixed by the second limiting member 510 and the fastener 512. The fastener 512 can be a screw, and the limiting hole 30 is a threaded hole. The second limiting member 510 is fixed by screwing the screw into the limiting hole 30.

[0056] In this embodiment, the first limiting member 50 can be screwed to one end of the movable rod 3. When the first limiting member 50 rotates and moves toward the base 1, it will cause the movable rod 3 to move in the opposite direction, thereby causing the second limiting member 510 to move closer to the first limiting member 50. This allows the end face of the second limiting member 510 near the first limiting member 50 to be embedded in the first through hole 10, clamping the base 1 with the first limiting member 50 and the second limiting member 510 to restrict the movable rod 3 on the base 1 and apply a preload force to the electrode 4. When the first limiting member 50 rotates and moves away from the base 1, it will cause the movable rod 3 to move in the opposite direction, thereby causing the second limiting member 510 to move away from the first limiting member 50. This allows the end face of the second limiting member 510 near the first limiting member 50 to be embedded out of the first through hole 10, releasing the base 1 and allowing the movable rod 3 to disengage from the base 1.

[0057] As a preferred embodiment, see Figure 2 and Figure 3 As shown, a push-in port 11 communicating with the first through hole 10 is also provided at the top of one end of the base 1. When the base 1 is released, one end of the movable rod 3 can enter or exit the first through hole 10 through the push-in port 11.

[0058] In this embodiment of the application, by setting a push-in port 11, one end of the movable rod 3 can directly enter or exit the first through hole 10 from the push-in port 11 when the base 1 is released, which facilitates the disassembly and installation of the movable rod 3 on the base 1.

[0059] As an optional embodiment, see Figure 2 and Figure 3 As shown, the base 1 includes a fixed seat 12 and a limiting seat 13 arranged at relatively intervals. The two ends of the fixed rod 2 and the movable rod 3 are respectively connected to the fixed seat 12 and the limiting seat 13, and the limiting mechanism 5 is arranged at the end of the movable rod 3 near the limiting seat 13.

[0060] In this embodiment, the base 1 is divided into two parts to achieve a parallel and stable connection between the fixed rod 2 and the movable rod 3. The limiting mechanism 5 is located at the end of the movable rod 3 near the limiting seat 13, so that when the limiting mechanism 5 moves towards the limiting seat 13, the limiting mechanism 5 can limit the movable rod 3 to the limiting seat 13; when the limiting mechanism 5 moves away from the limiting seat 13, the limiting mechanism 5 can separate from the limiting seat 13, so that the movable rod 3 can disengage from the limiting seat 13.

[0061] As a preferred embodiment, see Figure 2 and Figure 3 As shown, the fixed base 12 is provided with an insertion port 14, and the movable rod 3 is provided with a plug 31 at one end near the fixed base 12. The plug 31 is inserted into the insertion port 14.

[0062] The insertion port 14 in this embodiment can be set as square, and the cross-section of the plug-in 31 can also be set as square. After the plug-in 31 is inserted and engaged with the insertion port 14, the rotation of the movable rod 3 can be prevented.

[0063] As a preferred embodiment, see Figure 2 and Figure 3 As shown, the fixed base 12 and the limiting base 13 are provided with two mounting holes 15 through each other, and the two ends of the fixed rod 2 are respectively inserted into the two mounting holes 15; the clamping device also includes two fixing members 6, which are respectively provided at the two ends of the fixed rod 2 and respectively cooperate with the fixed base 12 and the limiting base 13 to limit the movement of the fixed rod 2.

[0064] In this embodiment, the two ends of the fixing rod 2 are fixed to the fixing seat 12 and the limiting seat 13 by two fixing members 6 respectively, which can prevent the movement of the fixing rod 2 (including but not limited to rotation and movement along the axis of the fixing rod 2) during the guiding process.

[0065] As an optional embodiment, see Figure 4 and Figure 5 As shown, the first end of the electrode 4 passes through the clamping gap around the outer periphery of the fixing rod 2 and extends to the electrode 4 itself to form an overlapping area 40.

[0066] In this embodiment, the electrode 4 is fixed between the fixed rod 2 and the movable rod 3, and the first end of the electrode 4 also forms an overlap area 40 with itself. This means that the clamping force of the clamping device on the electrode 4 includes not only the frictional force between the electrode and the fixed rod 2 and the movable rod 3, but also the frictional force between the electrodes 4 themselves. Before traction begins, the clamping of the electrode 4 is mainly handled by the pre-tightening force of the clamping device. That is, the fixed rod 2 and the movable rod 3 press the middle electrode 4, and it is clamped by the frictional force between the electrode 4 and the two rollers. Because the pre-tightening force is low, the frictional force is also relatively small. When traction begins, since the clamping force and the traction force on the electrode 4 are the same in magnitude but opposite in direction, the traction force increases, which increases the pressure between the electrode 4 and the two rollers, and the frictional force increases (i.e., the clamping force increases). Simultaneously, the greater the traction force on the electrode 4, the greater the mutual pressing force between the two electrodes in the overlap area 40, and the greater the mutual frictional force (i.e., the greater the clamping force). Figure 1 Compared to adhesive fastening, which uses constant adhesive force, the electrode is prone to detachment when resistance fluctuates. However, the embodiments of this application achieve dynamic adjustment of the clamping force, thus achieving a self-tightening effect.

[0067] Corresponding to the aforementioned application function implementation device embodiments, this application also provides an electrode guide device and corresponding embodiments.

[0068] Figure 6 This is a schematic diagram showing the usage state of the electrode lead-in device as illustrated in the embodiments of this application.

[0069] See Figure 6 An electrode guide device is characterized in that it includes a guide seat 7 and the aforementioned clamping device, the clamping device being fixed on the guide seat 7 and being able to move along the guide direction of the electrode 4 under the traction of the guide seat 7, so as to guide the electrode 4 onto a plurality of rollers 8 of the conveying device.

[0070] In the electrode feeding device of this embodiment, the clamping device is fixed on the feeding seat 7, so that the clamping device can move synchronously with the feeding seat 7. When feeding the electrode, the limiting mechanism 5 can be moved away from the base 1 first, and the limiting mechanism 5 is separated from the base 1; then the movable rod 3 is removed from the base 1, and the electrode 4 to be fed is wrapped around the fixed rod 2; then the movable rod 3 is installed on the base 1, and the limiting mechanism 5 is moved closer to the base 1, and the limiting mechanism 5 is limited to the base 1, fixing the movable rod 3 to the base 1; finally, the clamping device can be pulled to move along the feeding direction of the electrode 4 by the movement of the feeding seat 7, so as to feed the electrode 4 onto the multiple rollers 8 of the conveying device, thereby realizing the feeding of the electrode 4.

[0071] The electrode feeding device of this application embodiment is applicable to equipment that requires feeding operation, such as coating machines, rolling mills, slitting machines, and winding machines, and provides a simple and reliable electrode clamping function during the feeding process.

[0072] As an optional embodiment, see Figure 6 The guide seat 7 is a chain structure, and the base 1 of the clamping device is provided with a connecting shaft 16, which is disposed through the shaft hole of a link 70 of the chain structure.

[0073] In this embodiment, the guide seat 7 is the guide chain of the original electrode guide device. The base 1 of the clamping device is fixed on the guide seat 7, and the clamping device drives the electrode 4 to move through the traction of the chain. In this embodiment, a connecting shaft 16 is provided on the base 1 and is disposed through a shaft hole of a link 70 of the chain structure. The connecting shaft 16 can also be fixed in the shaft hole by tightening with double nuts to prevent the connecting shaft 16 from loosening during the guide process and achieve stable guide.
