Description

Technical Field

[0001] This utility model belongs to the field of battery manufacturing technology, specifically relating to a quick-release strapping mechanism. Background Technology

[0002] Battery electrodes are a core component of lithium batteries, directly affecting the battery's energy density, cycle life, and safety. In lithium battery manufacturing, electrodes coated with active materials are mainly transported and processed through a continuous conveying mechanism. The conveying mechanism pulls the electrode tape along the conveyor belt, which then passes through processes such as coating, drying, and rolling.

[0003] The belt threading mechanism typically includes a belt threading rod for pulling the belt. The belt threading rod is driven by a traction assembly for moving the belt threading rod. The traction assembly includes a sprocket and a chain that mesh with each other. The sprocket is sleeved on the belt threading rod and can drive the belt threading rod to move along the chain. After the belt is bonded to the belt threading rod by an adhesive tape, the belt threading rod pulls the belt for transmission under the drive of the traction assembly.

[0004] However, the conveying mechanism of the sprockets and chain in the threading system encounters certain resistance, making it difficult for the traction component to thread the material over long distances. Therefore, the threading mechanism needs to perform segmented threading to transport the material to different workstations. Segmented threading involves switching between different threading rods, at which point the material needs to be cut and re-bonded to different threading rods. This repeated cutting and bonding of the material is time-consuming and labor-intensive, and the material is prone to cracking with increasing number of connections, ultimately leading to the scrapping of the electrode sheets. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a quick-release tape threading mechanism. After the tape is wound around the winding rod, the winding rod and the clamping assembly hold the tape. During the tape threading process in segments, there is no need to cut and bond the tape multiple times, making the operation convenient and reducing the number of tape splices, thus reducing the possibility of tape scrap.

[0006] The technical effects to be achieved by this utility model are realized through the following technical aspects:

[0007] This utility model provides a quick-release belt threading mechanism, including a winding rod for winding a material belt; a belt clamping assembly including a clamping rod for clamping the material belt in conjunction with the winding rod, the clamping rod being detachably connected to the winding rod; an adapter seat disposed on the winding rod; and a driving assembly being kinetically connected to the adapter seat, the driving assembly driving the adapter seat to convey the material belt.

[0008] In some implementations, the winding rod includes a plug-in portion, and a telescopic component is provided between the plug-in portion and the adapter seat. The plug-in portion is detachably connected to the adapter seat via the telescopic component.

[0009] In some implementations, the telescopic assembly includes a connector disposed on the adapter; a sleeve passing through the connector and inserted into the connector; and an elastic member disposed on one side of the sleeve and located within the connector, the sleeve abutting against the connector via the elastic member.

[0010] In some implementations, a guide member is provided between the sleeve and the insertion part to guide the movement direction of the sleeve.

[0011] In some implementations, the sleeve has a guide hole, the guide is a guide screw, the guide screw is threadedly connected to the plug-in part, the threaded end of the guide screw passes through the plug-in part into the guide hole, and the guide screw is slidably connected to the sleeve.

[0012] In some implementations, a stop structure for assisting in fixing the clamping rod is provided between the clamping rod and the adapter seat.

[0013] In some implementations, the clamping rod includes a connecting portion, and the stop structure is disposed between the connecting portion and the adapter seat. The stop structure includes a stop sleeve fitted onto the connecting portion and a clamping member detachably connected to the adapter seat. When the stop sleeve is inserted into the adapter seat, the clamping member causes the stop sleeve and the adapter seat to abut against each other, thereby restricting the movement of the stop sleeve relative to the adapter seat.

[0014] In some implementations, the stop sleeve is detachably connected to the connecting part, and the stop sleeve has a slot for the abutment to pass through. When the stop sleeve is separated from the adapter, the abutment is engaged or disengaged from the slot.

[0015] In some implementations, the stop sleeve has a sliding hole, and a connector is provided between the stop sleeve and the connecting part at the sliding hole to fix or loosen the stop sleeve.

[0016] In some implementations, a clamping screw is provided between the winding rod and the clamping rod. The clamping screw passes through the clamping rod and the winding rod in sequence and is threadedly connected to the clamping rod and the winding rod respectively.

[0017] In summary, this utility model has at least the following advantages:

[0018] The quick-release tape threading mechanism provided by this utility model involves winding the tape around a winding rod during tape threading. A clamping rod, in conjunction with the winding rod, holds the tape wound around the clamping rod, thus fixing the end of the tape. A drive assembly moves the adapter seat, and the winding rod and clamping rod can pull the tape to convey it to different workstations. Compared to traditional tape adhesive fixing, the tape is convenient to assemble and disassemble, saving time and effort.

[0019] During the segmented conveying process, the winding rod can be separated from the transfer seat of the previous section. The winding rod and the clamping rod drive the clamped material strip into the next section of conveying. The winding rod is connected to the corresponding transfer seat. The material strip does not need to be cut and glued multiple times when it is segmented and threaded, which helps to reduce the possibility of the material strip cracking due to multiple splices, thus leading to the scrapping of the electrode sheet.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0031] Example 1:

[0032] Please see Figure 1 and Figure 2 The quick-release belt threading mechanism of this utility model can be used for film material conveying, especially in coating machines and drying ovens. The quick-release belt threading mechanism pulls the electrode sheet along the belt, improving the convenience of electrode sheet threading operation.

[0033] The quick-release strapping mechanism of this utility model includes a winding rod 2, on which a material strip 6 is wound. A clamping assembly 3 is provided on one side of the winding rod 2. The clamping assembly 3 includes a clamping rod 31 for cooperating with the winding rod 2 to clamp the material strip 6. The clamping rod 31 is detachably connected to the winding rod 2. In some specific embodiments, the clamping rod 31 is arranged parallel to the winding rod 2. When fixing the material strip 6, the material strip 6 can be wound multiple times on the winding rod 2 first. The clamping rod 31 and the winding rod 2 are assembled to clamp the multiple layers of material strip 6 wound on the winding rod 2. The material strip 6 continues to be wound, and the material strip 6 wraps around the clamping rod 31 and the winding rod 2. The multiple layers of material strip 6 are beneficial to ensuring the stability of the clamping of the material strip 6.

[0034] A connecting seat 1 is provided on the winding rod 2. Specifically, the connecting seat 1 is located at both ends of the winding rod 2 along its axial direction. A chain seat 41 is provided on the side of the connecting seat 1 away from the winding rod 2, and the connecting seat 1 is connected to the chain seat 41. The chain seat 41 is driven by a drive assembly 4 for driving the chain seat 41 and the connecting seat 1 to convey the material belt 6. In some specific embodiments, the drive assembly 4 includes a chain 42, which is detachably connected to the chain seat 41. The chain 42 is meshed with a sprocket, and the sprocket is rotatably connected to a motor. The output end of the motor is driven by the sprocket and drives the sprocket to rotate. The rotation of the sprocket then drives the chain 42 to convey the material. The chain seat 41 is conveyed along with the chain 42 and drives the connecting seat 1 and the winding rod 2 to convey the material belt 6 to different workstations.

[0035] When the material strip 6 is segmented, the adapter 1 of the previous link, driven by the drive assembly 4, has already conveyed the winding rod 2, clamping rod 31, and the traction material strip 6 to the corresponding workstation. The winding rod 2 separates from the adapter 1 of the previous link, and the winding rod 2 and clamping rod 31 pull the material strip 6 to the adapter 1 of the next link. The winding rod 2 connects to the adapter 1 of the next link, and the adapter 1 of the next link can then convey the material strip 6 along the chain 42 to the next workstation through the traction of the winding rod 2 and clamping rod 31. During the segmented conveying process of the material strip 6, only one set of winding rod 2 and clamping rod 31 is needed, which helps to save costs. At the same time, compared with the traditional threading mechanism, there is no need for multiple cutting and re-bonding of the electrode sheets, making the operation convenient. The number of splices of the material strip 6 is reduced, which can effectively solve the problem of the material strip 6 cracking due to multiple splices, thus causing the electrode sheets to be scrapped. The reduction in the number of scrapped electrode sheets can play a role in reducing costs and improving efficiency.

[0036] Example 2:

[0037] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the winding rod 2 of this utility model. Please refer to [link / reference]. Figures 2-5 .

[0038] Please see Figure 2 In this embodiment, the winding rod 2 includes a plug-in part 21, and a telescopic component 5 is provided between the plug-in part 21 and the chain seat 41. The plug-in part 21 is detachably connected to the chain seat 41 via the telescopic component 5.

[0039] Please see Figure 3 and Figure 4 In a preferred embodiment, the telescopic assembly 5 includes a connector 51, which is disposed on the chain seat 41. Specifically, the connector 51 is coaxially arranged with the winding rod 2. A sleeve 52 is passed through the connector 21, wherein the sleeve 52 is coaxially arranged with the connector 51 and the sleeve 52 is inserted into the connector 51. An elastic element 53 is disposed inside the connector 21, and the elastic element 53 is located on one side of the sleeve 52. Specifically, the elastic element 53 is preferably, but not limited to, a spring, and the elastic element 53 can be disposed at one or both ends of the winding rod 2. The end of the winding rod 2 without the elastic element 53 can be inserted into the connector 51 through the connector 21. The winding rod 2 and the adapter seat 1 are assembled.

[0040] When the sleeve rod 52 is pressed, it compresses the elastic element 53, and extends into the insertion part 21. The sleeve rod 52 can then be separated from the insertion connector 51, allowing the winding rod 2 to be detachably connected to the adapter seat 1. When the sleeve rod 52 is released, the elastic element 53 returns to its original position, and the sleeve rod 52 extends out of the insertion part 21 under the action of elastic force and abuts against the insertion connector 51. The winding rod 2 is then assembled and fixed with the chain seat 41, and the insertion part 21 is quickly disassembled and assembled with the adapter via the telescopic component 5.

[0041] Please see Figure 4 and Figure 5 In some specific embodiments, a guide member 54 is provided between the sleeve 52 and the insertion part 21 to guide the movement direction of the sleeve 52. The guide member 54 restricts the rotation of the sleeve 52 around the axis, which can improve the stability of the insertion of the sleeve 52 and the insertion part 51. Specifically, a guide hole 521 is provided on the sleeve 52. The guide hole 521 is a long through hole. The length direction of the guide hole 521 is consistent with the compression direction of the elastic member 53. The guide member 54 is a guide screw. The guide screw is threadedly connected to the insertion part 21. The threaded end of the guide screw passes through the insertion part 21 into the guide hole 521. When the elastic member 53 extends and retracts to drive the sleeve 52 to slide relative to the insertion part 21, the guide screw is slidably connected to the sleeve 52.

[0042] Before the material strip 6 is drawn, it is wound around the winding rod 2. The clamping rod 31 is detachably connected to the winding rod 2 to clamp the multi-layer material strip 6 wound on the winding rod 2. When it is necessary to pull the material strip 6 to the next link, the plug part 21 and the plug connector 51 are separated by the telescopic component 5. The winding rod 2 and the clamping rod 31 are detached from the adapter seat 1 of the link. The winding rod 2 and the clamping rod 31 pull the material strip 6 into the next link. The plug part 21 of the winding rod 2 is assembled with the plug connector 51 on the adapter seat 1 of the next link. The winding rod 2 and the clamping rod 31 can easily realize the segmented drawing of the material strip 6.

[0043] Example 3:

[0044] The difference between this embodiment and the above embodiments is that this embodiment further optimizes the structure of the clamping rod 31 of this utility model. Please refer to [link / reference]. Figure 6 and Figure 7 .

[0045] In this embodiment, a stop structure 32 for assisting in fixing the clamping rod 31 is provided between the clamping rod 31 and the adapter seat 1. In a preferred embodiment, the clamping rod 31 includes a connecting portion 311, and the stop structure 32 is disposed between the connecting portion 311 and the adapter seat 1. The stop structure 32 includes a stop sleeve 321, which is sleeved on the connecting portion 311. Specifically, the stop sleeve 321 can be a C-shaped sleeve. It is understood that this is not the only limitation on the shape of the stop sleeve 321, and those skilled in the art can make adjustments.

[0046] The stop sleeve 321 and the connecting part 311 are detachably connected. In some specific embodiments, the stop sleeve 321 has a sliding hole 3212, which is an oblong hole and its length direction is consistent with the length direction of the clamping rod 31. A connector 323 is provided between the stop sleeve 321 and the connecting part 311. The connector 323 passes through the sliding hole 3212 to fix or loosen the stop sleeve 321. Preferably, the connector 323 is a positioning screw. The threaded end of the positioning screw passes through the sliding hole 3212 and is threadedly connected to the connecting part 311. The positioning screw adjusts the distance between the stop sleeve 321 and the adapter 1.

[0047] A retaining member 322 is detachably connected to the adapter 1. When the stop sleeve 321 is inserted into the adapter 1, the retaining member 322 causes the stop sleeve 321 and the adapter 1 to abut against each other, thereby restricting the movement of the stop sleeve 321 relative to the adapter 1. In some specific embodiments, the stop sleeve 321 has a slot 3211 through which the retaining member 322 passes. When the stop sleeve 321 is separated from the adapter 1, the retaining member 322 is engaged or disengaged from the slot 3211. Preferably, the retaining member 322 is a shoulder screw, which is threadedly connected to the adapter 1. When the stop sleeve 321 is inserted into the adapter 1, the shoulder screw is loosened to engage the shoulder of the shoulder screw in the slot 3211, and then the shoulder screw is tightened. The shoulder screw causes the stop sleeve 321 and the adapter 1 to abut against each other, thereby restricting the movement of the stop sleeve 321. The stop structure 32 can help limit the movement of the winding rod 2 by locking the clamping rod 31, further ensuring the stability of the winding rod 2 and the clamping rod 31 in holding the material strip 6 during the belt guiding process. At the same time, by fixing and loosening the stop sleeve 321 through the connector 323, the clamping rod 31 can be removed from the adapter seat 1, improving the convenience of operation.

[0048] In a preferred embodiment, a clamping screw 22 is provided between the clamping rod 31 and the winding rod 2. Specifically, the clamping screw 22 is located between the connecting part 311 and the insertion part 21. The connecting part 311 has a fine adjustment hole. The threaded end of the clamping screw 22 passes through the fine adjustment hole and is threadedly connected to the connecting part 311 and the insertion part 21 respectively. The clamping screw 22 causes the winding rod 2 and the clamping rod 31 to clamp the material strip 6.
