Description

Technical Field

[0001] This utility model belongs to the technical field of winding devices, specifically relating to a material roll pushing device and a winding system. Background Technology

[0002] Currently, the production process of lithium battery cells is becoming increasingly mature. The front-end production processes, such as coating, rolling, and slitting, have basically formed standardized equipment. In the slitting equipment, cantilever air shafts or slip shafts are used to wind up the battery electrode sheets. After the roll is fully wound, a pushing device is used to push the roll onto the unloading vehicle (such as OHT), and then the unloading vehicle transports the roll to the material storage station.

[0003] Current feeding devices typically include a telescopic mechanism and a pusher arm controlled by the telescopic mechanism. The pusher arm pushes the material roll located at the take-up shaft, disassembling it for recycling. The telescopic mechanism usually uses a belt and telescopic linkage to achieve its telescopic function. However, when in the retracted state, the overall length of this telescopic mechanism is quite long, resulting in a large overall width of the device. To address this, some feeding devices use a two-stage linkage with overlapping sections to reduce the size of the device. However, the two-stage linkage telescopic structure is complex, usually requiring two tank chains for easy line passage. This causes inconvenience for installation and subsequent maintenance due to the complex inter-structure coordination, leading to a significant workload. Furthermore, since the pusher arm is usually located at the end of the telescopic mechanism and is typically a cantilever structure, its large end deflection can easily cause positioning inaccuracies.

[0004] In recent years, industrial production equipment has gradually moved towards simpler and more compact structures to improve space utilization and assembly efficiency during production, which is of great significance for improving overall production efficiency. Therefore, providing a simple and miniaturized feeding device is of great importance to lithium battery cell production and is a direction that researchers in related technical fields urgently need to study and solve.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0038] Example 1:

[0039] Please see the appendix Figure 1-3 This embodiment provides a material roll pushing device, including a rigid chain drive mechanism 100, a telescopic mechanism 200, and a pushing arm mechanism 300. This material roll pushing device achieves a simple structure, miniaturization, and ease of installation and maintenance by optimizing the structure between the rigid chain drive mechanism 100, the telescopic mechanism 200, and the pushing arm mechanism 300.

[0040] Specifically, in the initial state, both the rigid chain drive mechanism 100 and the telescopic mechanism 200 are located at one end of the roll pusher. The rigid chain drive mechanism 100 includes a rigid chain drive motor 10 and a rigid chain drive assembly 20. The rigid chain drive assembly 20 includes a housing assembly 21 fixed to one end of the roll pusher and a rigid chain assembly 22 housed inside the housing assembly 21. The rigid chain assembly 22 is wound inside the housing assembly 21, with one end fixedly connected to the housing assembly 21 and the other end being a movable end that telescopically connects to the housing assembly 21. The movable end of the rigid chain assembly 22 is connected to the pusher arm mechanism 300.

[0041] The telescopic mechanism 200 includes several telescopic rods 30, which are nested in a hierarchical manner to enable the telescopic mechanism 200 to extend and retract. The telescopic rod 30 closest to the receiving shell assembly 21 remains fixed in position; that is, the end containing the receiving shell assembly 21 is the fixed end of the material roll pushing device. The telescopic mechanism 200 extends or retracts with the relative movement of the telescopic rods 30, and the extension / retraction direction of the telescopic mechanism 200 is parallel to the extension / retraction direction of the rigid chain assembly 22.

[0042] The pusher arm mechanism 300 includes a pusher arm 40 for pushing the material roll and a rotary motor 41 for driving the pusher arm 40 to rotate. The pusher arm mechanism 300 is connected to the movable end of the rigid chain assembly 22 and the movable end of the telescopic mechanism 200. During operation, the rigid chain drive motor 10 drives the rigid chain assembly 22 to move from the receiving shell assembly 21 towards the movable end, while the telescopic rods 30 move relative to each other, causing the telescopic mechanism 200 to extend as a whole. The multi-stage telescopic mechanism 200 helps increase the overall structural rigidity of the material roll pushing device. As the telescopic mechanism 200 and the rigid chain assembly 22 move, the pusher arm mechanism 300, located at the ends of the telescopic mechanism 200 and the rigid chain assembly 22, also moves towards the movable end until the pusher arm mechanism 300 approaches the material roll.

[0043] Specifically, after the material roll at the spool is fully wound, the material roll pushing device receives a pushing command. The rotary motor 41 drives the pushing arm 40 to rotate to the spool position. Subsequently, the rigid chain drive motor 10 starts working, driving the rigid chain assembly 22 to move from the fixed end where the receiving shell assembly 21 is located to the movable end away from the receiving shell assembly 21. The telescopic mechanism 200 extends until the pushing arm 40 moves to the spool and pushes the material roll, causing it to be unloaded from the spool. After the pushing is completed, the rigid chain drive motor 10 operates, the rigid chain assembly 22 retracts in the direction of the receiving shell assembly 21, and the telescopic mechanism 200 retracts until the pushing arm mechanism 300 returns to its initial position.

[0044] In the recycling state, most of the rigid chain assembly 22 is coiled and retracted into the housing assembly 21, while the telescopic rods 30 are sequentially nested within the outermost telescopic rod 30. At this time, the overall length of the material roll pushing device is relatively short, exhibiting high space utilization and miniaturization. Furthermore, the rigid chain drive mechanism 100 and the telescopic mechanism 200 are separate units, facilitating simple cooperation. The nested arrangement of the telescopic rods 30 eliminates the need for additional tank chains 52 for wiring, making the material roll pushing device convenient for installation and maintenance.

[0045] The telescopic mechanism 200 includes more than two telescopic rods 30, with a first telescopic rod 31 nested at the outermost layer and a second telescopic rod 32 nested at the innermost layer. The position of the first telescopic rod 31 is fixed relative to the receiving shell assembly 21 and is fixed to the fixed end of the material roll pushing device. A connecting member 33 is provided between the second telescopic rod 32 and the pushing arm mechanism 300. In the retracted state, the second telescopic rod 32 retracts into the interior of the adjacent telescopic rod 30, and the remaining telescopic rods 30 are successively stored inside the next telescopic rod 30 until all telescopic rods 30 are stored inside the first telescopic rod 31.

[0046] In some embodiments, the rigid chain assembly 22 includes a first chain 221 and a second chain 222, and the housing assembly 21 includes a first housing portion 211, a second housing portion 212, and a converging portion 213. The first chain 221 and the second chain 222 are respectively wound into the first housing portion 211 and the second housing portion 212, and the portions of the first chain 221 and the second chain 222 near their movable ends engage with each other at the converging portion 213 to form a rigid chain assembly 23. It should be noted that the outer sides of both the first chain 221 and the second chain 222 are provided with several teeth to facilitate the engagement of the first chain 221 and the second chain 222 at the converging portion 213 to form a complete rigid chain assembly 23. The end of the rigid chain assembly 23 is a movable end. The movement of the rigid chain assembly 22 outward from the housing assembly 21 refers to the outward movement of the interlocked rigid chain assembly 23. In this embodiment, the confluence portion 213 is located between the first storage portion 211 and the second storage portion 212, and is located in the middle of the storage shell assembly 21.

[0047] Furthermore, the end of the rigid chain assembly 23 is provided with a connecting seat 25, and the rigid chain assembly 22 is connected to the pusher arm mechanism 300 through the connecting seat 25.

[0048] Furthermore, the housing assembly 21 is also equipped with a sprocket 24, which is connected to the output end of the rigid chain drive motor 10 and to either the first chain 221 or the second chain 222. During operation, the rigid chain drive motor 10 drives the sprocket 24 to rotate, thereby causing the first chain 221 and the second chain 222 to extend or retract.

[0049] To increase the rigidity of the material roll pushing device, a support member 42 is provided between the rigid chain assembly 22 and the telescopic mechanism 200. The support member 42 connects the rigid chain assembly 23 and the telescopic rod 30 to support the rigid chain assembly 22. In this embodiment, the support member 42 is vertically arranged, and its two ends are connected to one of its telescopic rods 30 and the rigid chain assembly 23, respectively. In the retracted state, there is a portion of the telescopic mechanism 200 that is not fully nested into the outermost telescopic rod 30, and there is also a portion of the rigid chain assembly 22 that is not fully retracted into the housing assembly 21. The support member 42 connects these two portions.

[0050] In some embodiments, the roll pusher further includes a guide rail mechanism 50, which includes a guide rail 51, wherein the extension direction of the guide rail 51 is parallel to the extension and retraction direction of the rigid chain assembly 22, and the pusher arm mechanism 300 is movably connected to the guide rail 51. Under the driving action of the rigid chain drive mechanism 100, the pusher arm mechanism 300 eventually moves along the guide rail 51 to improve the rigidity of the roll pusher and also improve the accuracy of the pusher arm 40 during movement.

[0051] Example 2:

[0052] The difference between this embodiment and Embodiment 1 is that this embodiment provides a more detailed description of the pusher arm mechanism 300 of this utility model. For similarities, please refer to Embodiment 1. The pusher arm mechanism 300 will be further described below.

[0053] Please refer to Figures 1 to 2 The pusher arm mechanism 300 also includes a pusher base 43, and a slider 53 is provided on the guide rail 51. The pusher base 43 is movably connected to the guide rail 51 through the slider 53. The pusher base 43 provides support for the pusher arm 40 and limits its height, while also increasing the structural rigidity between the pusher arm mechanism 300 and the guide rail mechanism 50.

[0054] Furthermore, a tank chain 52 is provided between the guide rail 51 and the slider 53. The tank chain 52 is used for the routing of the material roll pushing device. Since the structure of the material roll pushing device in this embodiment is simple and the number of tank chains 52 is small, it is beneficial for the installation and maintenance of the material roll pushing device.

[0055] It should be noted that the material roll pushing device provided in this embodiment can be applied to the unloading of electrode rolls, as well as to the unloading of sheet or film materials in other fields.

[0056] Example 3:

[0057] This embodiment, based on the above embodiments, provides a winding system, which includes a winding device and a roll pushing device. The winding device includes a reel for mounting the roll and is used for winding or changing the roll. The roll pushing device pushes the roll via a pushing arm 40, thereby unloading the roll from the reel to facilitate subsequent roll replacement operations.

[0058] The material roll pushing device can be either Embodiment 1 or Embodiment 2, or a material roll pushing device provided by simply replacing Embodiment 1 and Embodiment 2.

[0059] The winding system, through the setting of the material roll pushing device, achieves the characteristics of compact layout, simplified structure and easy installation and maintenance, which helps to improve the efficiency of the winding system during operation.

[0060] The above description is merely an example and illustration of the structure of this utility model, and while the description is quite specific and detailed, it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these obvious substitutions all fall within the protection scope of this utility model.
