[0002] In the manufacturing process of batteries (e.g., lithium-ion batteries), the unwinding of electrode rolls is a continuous production step. In practical applications, depending on process requirements or equipment layout, it is sometimes necessary to change the unwinding direction of the rolls.

This series of operations is extremely cumbersome, wastes a lot of time, and affects production efficiency. Utility Model Content

[0004] This utility model provides an electrode unwinding device, including an unwinding assembly, a driving component, and a rotating component.

[0005] The unwinding assembly includes an unwinding roller for winding the electrode strip.

[0006] The drive component and the unwinding roller are connected by a clutch structure, allowing the drive component and the unwinding roller to move closer together, thus driving the unwinding roller to rotate; or, the drive component and the unwinding roller to move away from each other, thus disengaging the drive component from the unwinding roller.

[0007] The rotating component is used to drive the unwinding roller to rotate a preset angle in the horizontal direction when the driving component is disengaged from the unwinding roller.

[0008] As one possible implementation, the clutch structure includes a movable clutch and a fixed clutch. The movable clutch reciprocates along the axis of the unwinding roller, moving closer to or away from the fixed clutch. One of the movable clutch and the fixed clutch is connected to the unwinding assembly, and the other is connected to the drive component.

[0009] The clutch structure includes a first moving clutch and a second moving clutch. The first moving clutch and the second moving clutch reciprocate on the axis of the unwinding roller. One of the first moving clutch and the second moving clutch is connected to the unwinding assembly, and the other is connected to the drive component.

[0010] As one possible implementation, the moving clutch is configured as a linear slider, including a linear slide rail and a slider slidably connected to the linear slide rail, and the fixed clutch is configured as a fixed support frame.

[0011] The linear slide rail extends in the same direction as the axis of the unwinding roller. The slider drives the unwinding roller to reciprocate. The driving component is connected to the fixed support frame.

[0012] As one possible implementation, one of the unwinding roller and the drive shaft of the drive member is provided with a mating part, and the other is provided with a deformation mating part.

[0013] The deformable mating part can be deformed to have a locked state and an unlocked state. When the deformable mating part is in the locked state, the mating part is locked to the deformable mating part so that the drive shaft of the drive member drives the unwinding roller to rotate. When the deformable mating part is in the unlocked state, the mating part is unlocked to the deformable mating part so that the drive shaft of the drive member is disengaged from the unwinding roller.

[0014] As one possible implementation, the unwinding roller is provided with the deformation fitting part, the deformation fitting part is configured as a variable diameter through hole, and the fitting part is configured as the drive shaft of the drive member.

[0015] When the variable diameter through hole is in the locked state, the radial dimension of the variable diameter through hole is adapted to the radial dimension of the drive shaft; when the variable diameter through hole is in the unlocked state, the radial dimension of the variable diameter through hole is greater than the radial dimension of the drive shaft.

[0016] As an alternative implementation, the unwinding roller is a keyed air shaft or a tile-type air shaft.

[0017] As an alternative implementation, when the variable diameter through hole is in the unlocked state, the drive shaft passes through at least the entire variable diameter through hole.

[0018] As an alternative implementation, the unwinding assembly further includes a roll mounting bracket for mounting the unwinding roll, and the rotating component includes a fixed base and a rotating output end mounted on the fixed base.

[0019] The rotary output end is connected to the surface of the roll mounting frame facing away from the unwind roll, and the slider is connected to the fixed base.

[0020] As an alternative implementation, a linear telescopic component and a base are also included. The movable end of the linear telescopic component reciprocates in the vertical direction. The movable end of the linear telescopic component is connected to the base. The fixed support frame and the linear slide rail are connected to the base.

[0021] As an implementation method, the rotating component includes a cam divider and a swing cylinder, and the rotating component drives the unwinding roller to rotate 180° in the horizontal direction.

[0022] In the above-described solution, this application utilizes a clutch structure to connect and disconnect the rotating component from the unwinding roller. The moving clutch performs linear motion in the direction of the unwinding roller's axis, which helps ensure the connection accuracy between the drive shaft of the drive component and the unwinding roller. Simultaneously, the short stroke of the linear motion helps reduce the time required for the entire process of reversing the unwinding roller's direction. The entire process of reversing the unwinding roller's direction is simple and convenient, avoiding the cumbersome process of using a forklift for handling. Furthermore, compared to the space required for forklift handling, the space required for reversing the unwinding roller's direction is significantly reduced. Attached Figure Description

[0034] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] In the manufacturing process of batteries (e.g., lithium-ion batteries), the unwinding of electrode rolls is a continuous production step. In practical applications, depending on process requirements or equipment layout, it is sometimes necessary to change the unwinding direction of the rolls.

[0037] In related technologies, a forklift is required to manually unload the unwinding roller 11, which is wrapped with electrode material, and then the forklift is used to reverse the direction of the unwinding roller on the roller mounting frame. Finally, the reversed unwinding roller is installed on the roller mounting frame. This series of operations is extremely cumbersome, wastes a lot of time, and affects production efficiency.

[0038] Based on this, this application proposes an electrode unwinding device that can rotate the unwinding roller by 180°, with a short rotation time, which helps to improve production efficiency.

[0039] In detail, such as Figures 1-7 As shown, the electrode unwinding device includes an unwinding assembly 10, a drive member 20, and a rotating member 30. The unwinding assembly 10 includes an unwinding roller 11, which is used to wind the electrode strip. The drive member 20 and the unwinding roller 11 are connected by a clutch structure, which allows the drive member 20 and the unwinding roller 11 to move closer together, thereby driving the unwinding roller 11 to rotate, or the drive member 20 and the unwinding roller 11 to move further apart, thereby disengaging the drive member 20 from the unwinding roller 11. The rotating member 30 is used to rotate the unwinding roller 11 by a preset angle in the horizontal direction when the drive member 20 is disengaged from the unwinding roller 11.

[0040] It should be noted that the preset angle can be approximately 180°, such as 181°, 183°, 185°, 175°, 179°, etc. Of course, the preset angle can be 180°.

[0041] The clutch structure includes a moving clutch and a fixed clutch. The moving clutch reciprocates on the axis of the unwinding roller 11, moving closer to or away from the fixed clutch. One of the moving clutch and the fixed clutch is connected to the unwinding assembly 10, and the other is connected to the drive unit 20.

[0042] like Figure 1 and Figure 2As shown, the drive component 20 can be a drive motor, including a drive shaft 21, which drives the unwinding roller 11 to rotate; the unwinding assembly 10 includes the unwinding roller 11 and a roller mounting frame 12 for mounting the unwinding roller 11. The moving clutch is configured as a linear slide 60, including but not limited to a linear slide rail 61 and a slider 62 slidably connected to the linear slide rail 61; the fixed clutch is configured as a fixed support frame 40. The rotating component 30 includes a fixed base (not shown) and a rotating output end (not shown) mounted on the fixed base; the rotating output end of the rotating component 30 is connected to the surface of the roller mounting frame 12 facing away from the unwinding roller 11.

[0043] In one embodiment, such as Figure 3-5 As shown, the linear guide rail 61 extends in the same direction as the axis of the unwinding roller 11. The slider 62 is connected to the fixed seat of the rotating component 30, and the drive component 20 is connected to the fixed support frame 40. In this way, the slider 62 drives the rotating component 30 to reciprocate in the axial direction of the unwinding roller 11, and the rotating component 30 drives the roller mounting frame 12 to reciprocate in the axial direction of the unwinding roller 11. As a result, the roller mounting frame 12 drives the unwinding roller 11 to move closer to or away from the drive shaft 21 of the drive component 20.

[0044] The above configuration uses a clutch structure to connect and disconnect the rotating component 30 from the unwinding roller 11. The movable clutch moves linearly in the direction of the axis of the unwinding roller 11, which helps ensure the connection accuracy between the drive shaft 21 of the drive component 20 and the unwinding roller 11. Simultaneously, the short stroke of the linear motion helps reduce the time required for the entire process of reversing the direction of the unwinding roller 11. The movable clutch can be, but is not limited to, a cylinder, a hydraulic cylinder, or a ball screw.

[0045] In another embodiment, the linear guide rail 61 extends in the same direction as the axis of the unwinding roller 11, the slider 62 is connected to the drive member 20, and the fixed seat of the rotating member 30 is connected to the fixed support frame 40. In this way, the slider 62 drives the drive member 20 to reciprocate in the axial direction of the unwinding roller 11, and the drive shaft 21 of the drive member 20 can move closer to or further away from the unwinding roller 11.

[0046] Of course, it is understandable that the clutch structure may include a first moving clutch and a second moving clutch. The first moving clutch and the second moving clutch reciprocate on the axis of the unwinding roller 11. One of the first moving clutch and the second moving clutch is connected to the unwinding assembly 10, and the other is connected to the drive unit 20.

[0047] The following embodiments illustrate the use of a moving clutch connected to the unwinding assembly 10 and a fixed clutch connected to the drive unit 20:

[0048] One of the unwinding roller 11 and the drive shaft 21 of the drive member 20 is provided with a mating part, and the other is provided with a deformable mating part. The deformable mating part can be deformed to have a locked state and an unlocked state. When the deformable mating part is in the locked state, the mating part is locked to the deformable mating part, so that the drive shaft 21 of the drive member 20 drives the unwinding roller 11 to rotate. When the deformable mating part is in the unlocked state, the mating part is unlocked to the deformable mating part, so that the drive shaft 21 of the drive member 20 is disengaged from the unwinding roller 11.

[0049] In one specific embodiment, the unwinding roller 11 is provided with a deformation fitting part, which is configured as a variable diameter through hole 111. The drive shaft 21 of the drive member 20 is configured as a fitting part. When the variable diameter through hole 111 is in the locked state, the radial dimension of the variable diameter through hole 111 matches the radial dimension of the drive shaft 21; when the variable diameter through hole 111 is in the unlocked state, the radial dimension of the variable diameter through hole 111 is greater than the radial dimension of the drive shaft 21.

[0050] In detail, such as Figure 6 and Figure 7 As shown, the unwinding roller 11 has a variable diameter through hole 111 inside, and the axis of the variable diameter through hole 111 is on the same straight line as the axis of the unwinding roller 11. The radial dimension of the variable diameter through hole 111 can be varied, including a first radial dimension 1111 and a second radial dimension 1112. The first radial dimension 1111 is larger than the second radial dimension 1112, and the second radial dimension 1112 matches the radial dimension of the drive shaft 21.

[0051] The drive shaft 21 of the drive component 20 is disposed within the variable diameter through hole 111 of the unwinding roller 11. At the current moment, the variable diameter through hole 111 is in a locked state, and the radial dimension of the variable diameter through hole 111 is the second radial dimension 1112, so that the variable diameter through hole 111 and the drive shaft 21 of the drive component 20 are locked together. When the drive shaft 21 of the drive component 20 rotates, the drive shaft 21 drives the unwinding roller 11 to rotate, wherein the first end a of the unwinding roller 11 faces to the left and the second end b faces to the right.

[0052] According to requirements, the direction of the unwinding roller 11 is reversed. The variable diameter through hole 111 switches from the locked state to the unlocked state, and the radial dimension of the variable diameter through hole 111 changes from the second radial dimension 1112 to the first radial dimension 1111, so that the variable diameter through hole 111 disengages from the drive shaft 21 of the drive member 20, and a gap exists between the inner surface of the variable diameter through hole 111 and the drive shaft 21. Next, the slider 62 moves along the length extension direction of the linear slide rail 61, and the slider 62 drives the roller mounting bracket 12 away from the drive shaft 21 of the drive member 20, so that the variable diameter through hole 111 of the unwinding roller 11 moves away from the drive shaft 21 of the drive member 20, until there is a preset distance between the drive shaft 21 and the variable diameter through hole 111 of the unwinding roller 11 in the axial direction of the unwinding roller 11. Immediately afterwards, the rotating member 30 drives the roller mounting bracket 12 and the linear slide rail 61 to rotate 180° in the horizontal direction. At this moment, the first end a of the unwinding roller 11 faces to the right and the second end b faces to the left. It should be noted that the whole process of turning the unwinding roller 11 is simple and convenient, avoiding the cumbersome process of using a forklift for handling. At the same time, compared with the space required for forklift handling, the space required for turning the unwinding roller 11 is greatly reduced.

[0053] Then, slider 62 moves again along the length of linear guide rail 61, causing slider 62 to move the roller mounting bracket 12 closer to the drive shaft 21 of drive member 20, thereby bringing the variable diameter through hole 111 of unwinding roller 11 closer to the drive shaft 21 of drive member 20, until the variable diameter through hole 111 of unwinding roller 11 passes through the drive shaft 21 of drive member 20. Finally, the variable diameter through hole 111 switches from the unlocked state to the locked state, and the radial dimension of the variable diameter through hole 111 changes from the first radial dimension 1111 to the second radial dimension 1112, so that the variable diameter through hole 111 is locked and connected to the drive shaft 21 of drive member 20. In this way, the drive shaft 21 of drive member 20 rotates, and the drive shaft 21 can drive the unwinding roller 11 to rotate again.

[0054] This configuration allows the deformable fitting to switch between a locked and unlocked state. When the fitting is locked, the drive shaft 21 of the drive member 20 is locked to the unwinding roller 11, ensuring stable rotation of the unwinding roller 11. When the fitting is unlocked, the drive shaft 21 is disengaged from the unwinding roller 11, creating a gap that facilitates linear motion of the unwinding roller 11. The locking and unlocking processes are simple and ingeniously designed, enabling precise transmission and rapid separation between the drive shaft 21 and the unwinding roller 11.

[0055] The unwinding roller 11 is either a keyed air shaft or a tile-type air shaft. The keyed or tile-type air shaft has the aforementioned variable-diameter through hole 111, and the switching between the second radial dimension 1112 and the first radial dimension 1111 of the variable-diameter through hole 111 is achieved by adjusting the air pressure. Keyed or tile-type air shafts can be directly purchased, which helps reduce production costs.

[0056] The length of the drive shaft 21 is at least greater than or equal to the length of the variable diameter through hole 111. When the variable diameter through hole 111 is in the unlocked state, the drive shaft 21 penetrates at least the entire variable diameter through hole 111.

[0057] It should be noted that when the variable diameter through hole 111 is in the unlocked state, the gap between the inner surface of the variable diameter through hole 111 and the drive shaft 21 is on the order of centimeters, for example, 2cm, 2.5cm, 3cm, etc. During the process of the variable diameter through hole 111 being fitted onto the drive shaft 21, the drive shaft 21 essentially acts as a guide for the variable diameter through hole 111. The entire variable diameter through hole 111 is fitted onto the drive shaft 21, meaning that the drive shaft 21 always plays a guiding role during the movement of the variable diameter through hole 111. Furthermore, a larger contact area between the drive shaft 21 and the variable diameter through hole 111 helps the unwinding roller 11 rotate stably.

[0058] The rotating component 30 includes a cam divider and a swing cylinder. The cam divider and swing cylinder are precisely positioned, which helps to ensure the rotation angle, while also reducing the time required to change the direction.

[0059] Among them, such as Figure 1 As shown, the electrode unwinding device also includes a linear telescopic member 70 and a base 50. The movable end of the linear telescopic member 70 reciprocates in the vertical direction. The movable end of the linear telescopic member 70 is connected to the base 50. A fixed support frame 40 and a linear slide rail 61 are connected to the base 50.

[0060] In practical applications, other parts and mechanisms may exist around the unwinding roller 11, which may hinder its rotation direction. A linear telescopic component 70 can be used to raise or lower the unwinding roller 11 to a suitable height, avoiding interference from other parts and mechanisms in the surrounding environment, thus facilitating the rotation direction of the unwinding roller 11. The linear telescopic component 70 can be, but is not limited to, a cylinder, a hydraulic cylinder, or a ball screw.

[0061] In another specific embodiment, the drive shaft 21 of the drive member 20 is provided with a deformation fitting part, which is configured as a variable diameter shaft. The unwinding roller 11 is provided with a fitting part, which is configured as a through hole. When the variable diameter shaft is in the locked state, the radial dimension of the variable diameter shaft matches the radial dimension of the through hole; when the variable diameter shaft is in the unlocked state, the radial dimension of the variable diameter shaft is smaller than the radial dimension of the through hole.

[0062] In detail, the radial dimensions of the variable diameter shaft can vary, including a third radial dimension and a fourth radial dimension. The third radial dimension is greater than the fourth radial dimension. The third radial dimension matches the radial dimension of the through hole of the unwinding shaft, and the fourth radial dimension is smaller than the radial dimension of the through hole of the unwinding shaft.

[0063] In summary, this application utilizes a clutch structure to connect and disconnect the rotating component 30 from the unwinding roller 11. The movable clutch moves linearly in the direction of the axis of the unwinding roller 11, which helps ensure the connection accuracy between the drive shaft 21 of the drive component 20 and the unwinding roller 11. Simultaneously, the short stroke of the linear motion helps reduce the time required for the entire process of reversing the direction of the unwinding roller 11. The entire process of reversing the direction of the unwinding roller 11 is simple and convenient, avoiding the cumbersome process of using a forklift for handling. Furthermore, compared to the space required for forklift handling, the space required for reversing the direction of the unwinding roller 11 is significantly reduced.
