Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of electrode processing equipment, specifically relating to a tail material adsorption mechanism and a roll changing system. Background Technology
[0002] Electrodes are one of the important components of a battery cell. In the production of battery cells, electrodes are fed in the form of rolls. However, as the electrodes are wound up, the battery cell production process usually involves changing rolls, which involves cutting the old rolls of electrodes with a cutter and connecting the strip to the new electrodes, so that the electrodes continue to be fed.
[0003] During rewinding, as the electrode sheets are cut by the cutter, the connections between them are lost. The end of the substrate, the tail material, falls automatically under gravity, sometimes even landing on the ground. This results in some of the electrode substrate becoming contaminated and discarded. In a single rewinding cycle, 1-2 meters of substrate can be discarded due to contamination. In recent years, the demand for battery cell production has increased significantly, leading to frequent rewinding. Over time, this will accumulate a large amount of waste substrate, greatly increasing the production cost of battery cells.
[0004] Therefore, from the perspective of environmental protection, energy conservation, and reducing production costs, it is of great significance to provide a component that avoids waste of raw materials for battery cell production. Utility Model Content

The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. 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.
[0049] Example 1:
[0050] Please see the appendix Figure 1-5 This embodiment provides a tailings adsorption mechanism 100, including a fixed plate 1 and an adsorption assembly 2, a cutter assembly 3, and a brush roller assembly 4 connected between the fixed plate 1. The tailings adsorption mechanism 100 integrates the cutter assembly 3, the adsorption assembly 2, and the brush roller assembly 4 into one unit to adsorb the tailings of the substrate, thereby solving the problem of contamination of the tailings of the substrate during roll changing.
[0051] Specifically, the fixing plate 1 serves as the base for integrating the adsorption assembly 2, the cutter assembly 3, and the brush roller assembly 4. The adsorption assembly 2 includes a vacuum pump and a suction cup 21 for adsorbing substrate tail material, wherein the suction cup 21 extends entirely along a first direction. The first direction is the direction in which the lines connecting the fixing plates 1 are located.
[0052] It should be noted that, in order to simultaneously achieve the purposes of dividing the substrate and adsorbing the substrate, the tail material adsorption mechanism 100 is generally parallel to the direction of the substrate width, that is, the fixing plates 1 are distributed along the direction of the substrate width. At the same time, to ensure the stability of adsorption, the distance between the fixing plates 1 is preferably greater than the width of the substrate.
[0053] For ease of description, in the attached figures, the direction in which the fixed plate 1 is located is taken as the first direction and is plotted as the X-axis; the direction parallel to the surface of the fixed plate 1 is taken as the second direction and is plotted as the Y-axis; and the direction perpendicular to the plane containing the X-axis and Y-axis is taken as the third direction and is plotted as the Z-axis. The first direction, the second direction, and the third direction are all perpendicular to each other.
[0054] Furthermore, the cutting assembly 3 includes a cutting blade 32 and a transmission unit 31 for driving the cutting blade 32. Under the action of the transmission unit 31, the cutting blade 32 moves and cuts the substrate. The cutting blade 32 is located above the suction cup 21 to ensure that after the substrate is cut by the cutting blade 32, the substrate tail material located below can be promptly adsorbed by the suction cup 21.
[0055] The brush roller assembly 4 includes a brush roller 41 and a rotary motor 42. The brush roller 41 contacts the tail material and rotates under the action of the rotary motor 42, causing friction between the brush roller and the tail material and applying a force towards the suction cup 21, so that the tail material can be stably adsorbed onto the suction cup 21. The brush roller 41 is located below the suction cup 21 to facilitate cooperation with the tail material below. During operation, on the side of the brush roller 41 that abuts against the substrate, the rotation direction of the brush roller 41 is opposite to the direction of gravity acting on the tail material, thereby ensuring that the tail material is subjected to a force in the direction of the suction cup 21.
[0056] In some embodiments, to adapt to the position of the substrate conveyor, the fixing plate 1 is also provided with a guide rail assembly 5 to facilitate the movement of the cutting assembly 3 and the adsorption assembly 2. The guide rail assembly 5 extends along the Y-axis, and both the cutting assembly 3 and the adsorption assembly 2 are movably connected to the guide rail assembly 5. If the substrate is far from the tail material adsorption mechanism 100 during conveying, causing the cutting blade 32 and the suction cup 21 to be unable to work on the substrate, the cutting assembly 3 and the adsorption assembly 2 can move along the Y-axis along the guide rail assembly 5 to get closer to the substrate, ensuring a good cutting effect and timely adsorption of the substrate tail material. It is understood that in some embodiments, the cutting assembly 3 and the adsorption assembly 2 can be connected to different guide rail assemblies 5 respectively, and the number of guide rail assemblies 5 is not limited here.
[0057] In this embodiment, considering that both the cutting component 3 and the adsorption component 2 need to operate on the substrate, it is preferable to integrate the cutting component 3 and the adsorption component 2 into the same module. The cutting component 3 and the adsorption component 2 are connected to the same guide rail connecting plate 51, and are movably connected to the guide rail component 5 through the guide rail connecting plate 51, so as to uniformly adjust the position of the cutting component 3 and the adsorption component 2 in the Y-axis direction.
[0058] Furthermore, the guide rail assembly 5 is equipped with a cylinder 52 and a stop block 53 at both ends, and the output end of the cylinder 52 is drivenly connected to the guide rail connecting plate 51. The guide rail assembly 5 is provided with a track extending along the Y-axis direction, and the guide rail connecting plate 51 moves along the track under the action of the cylinder 52. In this embodiment, the cylinder 52 is an ultra-thin cylinder 52, and its output end is provided with a floating joint 54. The stop block 53 is located at the end opposite to the output end of the cylinder 52 and is installed on the fixed plate 1. As the floating joint 54 extends to the end of the track, the floating joint 54 will abut against the stop block 53, thereby braking the floating joint 54 to prevent the guide rail connecting plate 51 and the fixed cutter assembly 3 and adsorption assembly 2 from moving further.
[0059] To optimize the adsorption effect of the tail material adsorption mechanism 100, the brush roller 41 is preferably located on the adsorption side away from the suction cup 21. (See key reference) Figure 1 and Figure 5 In the Y-axis direction, the suction cup 21 of the adsorption assembly 2 preferably faces the outer side of the fixed plate 1. The brush roller 41 and the adsorption assembly 2 are respectively connected to both ends of the fixed plate 1, and the brush roller 41 is away from the adsorption direction of the suction cup 21. The purpose is to increase the interaction force between the substrate and the brush roller 41, and also to adapt to the conveyor path of the substrate. If the brush roller 41 is located directly below the suction cup 21, that is, the substrate is in a vertical position and in contact with the suction cup 21 and the brush roller 41, the force on the substrate is along the vertical direction, which makes the interaction force between the substrate and the brush roller 41 smaller, and the corresponding friction is smaller, which cannot ensure that the brush roller 41 plays a clear role. When the brush roller 41 is located below the suction cup 21 and away from the adsorption side of the suction cup 21, the substrate comes into contact with the brush roller 41 after passing the suction cup 21. At this time, the interaction force between the substrate and the suction cup 21, and between the substrate and the brush roller 41, is strengthened, thereby improving the role of the brush roller 41, and also conforming to the conveyor direction between different rolls.
[0060] In this embodiment, the brush roller assembly 4 includes brackets 43 disposed at both ends of the brush roller 41, and the brush roller 41 is connected to the guide rail connecting plate 51 through the brackets 43. In some embodiments, the brush roller 41 may also be connected to an adjustment structure to adjust the angle of the brush roller 41 relative to the guide rail connecting plate 51, thereby adapting to different conveyor belt paths and obtaining a better adsorption assistance effect.
[0061] To prevent the substrate from being creased, damaged, or even broken due to the components in the tail material adsorption mechanism 100 when passing through it, a acetal pad 7 is added to the tail material adsorption mechanism 100. In this embodiment, the acetal pad 7 is located above the suction cup 21. Furthermore, the portion of the tail material adsorption mechanism 100 that may come into contact with the substrate is preferably designed with rounded corners to reduce potential damage to the substrate caused by the tail material adsorption mechanism 100.
[0062] In addition, the tail material adsorption mechanism 100 is provided with a wire conduit 8 between the fixed plates 1. The wire conduit 8 is used to pass through the wires that provide electric power to the tail material adsorption mechanism 100, so as to simplify the tail material adsorption mechanism 100 and make the layout of the tail material adsorption mechanism 100 more reasonable.
[0063] Example 2:
[0064] The difference between this embodiment and Embodiment 1 is that the tailings adsorption mechanism 100 has undergone further structural optimization in this embodiment. For the similarities, please refer to Embodiment 1. The differences are explained below.
[0065] Please see Figures 6-8 The transmission unit 31 includes a pulley 311 located near the fixed plate 1, a drive motor 313 driven by the pulley 311, and a belt 312 sleeved on the outside of the pulley 311. The cutter 32 is connected to the belt 312. The drive motor 313 is driven by one of the pulleys 311, causing that pulley 311 to rotate actively. The other pulley 311 acts as a driven pulley, together causing the belt 312 to rotate. The cutter 32 is connected to one side of the belt 312 and moves along the X-axis under the action of the belt 312 to cut the substrate along the width of the substrate.
[0066] Furthermore, in this embodiment, the cutter 32 reciprocates along the X-axis. To this end, the transmission unit 31 also includes photoelectric switches 314 positioned near the pulleys 311 at both ends, with a moving guide rail 315 forming between the photoelectric switches 314 for the cutter 32. The placement of the photoelectric switches 314 restricts the movement area of the cutter 32, and the photoelectric switches 314 cooperate with the transmission motor 313, pulleys 311, and belt 312 to cause the cutter 32 to reciprocate between the moving guide rails 315.
[0067] It is understood that this is not the only limitation on the movement of the cutter 32. In some embodiments, the cutter 32 may also cut the substrate by extending or contracting relative to the substrate.
[0068] In addition, the tail material adsorption mechanism 100 in this embodiment also includes a protective plate 9. The protective plate 9 is located on the side away from the suction cup 21 for adsorption and partially surrounds the tail material adsorption mechanism 100, thereby improving the integrity of the tail material adsorption mechanism 100.
[0069] Example 3:
[0070] This embodiment, based on the above embodiments, provides a roll-changing system 200, which includes a tail material adsorption mechanism 100 and winding assemblies 210 disposed on both sides of the tail material adsorption mechanism 100. In some embodiments, the tail material adsorption mechanism 100 may be the tail material adsorption mechanism 100 provided in Embodiment 1 or Embodiment 2, or it may be a tail material adsorption mechanism 100 with simple improvements and replacements based on Embodiment 1 and Embodiment 2. In this embodiment, the tail material adsorption mechanism 100 is the tail material adsorption mechanism 100 provided in Embodiment 2.
[0071] The following describes one of the layout methods of the roll changing system 200.
[0072] like Figure 9 and Figure 10 As shown, the winding assembly 210 in the roll changing system 200 can be divided into an upper winding assembly 201 and a lower winding assembly 202. In this embodiment, the substrate 6 moves from the roll at the upper winding assembly 201 to the lower winding assembly 202, and the tail material adsorption mechanism 100 is located on the right side of the substrate 6 between the winding assemblies 210. Figure 10 A simplified schematic diagram of the substrate 6 and the tail material adsorption mechanism 100 is provided. The substrate 6 passes through the adsorption component 2 and the brush roller 41 in sequence and then connects to the roll of material in the lower winding component 202.
[0073] During operation, the cutting assembly 3, the suction assembly 2, and the brush roller assembly 4 can all move along the guide rail assembly 5 towards the substrate 6 until they come into contact with it. Then, the cutting assembly 3 moves to cut the substrate 6. At the instant the substrate 6 is cut, the vacuum pump provides negative pressure, giving the suction cup 21 suction force. This causes the tail material of the substrate 6 produced after cutting to be attracted by the suction cup 21 as it falls, preventing it from falling and causing unnecessary waste. During this process, the brush roller 41 rotates clockwise and generates friction with the substrate 6, keeping the tail material of the substrate 6 under an upward force, thus ensuring that the tail material of the substrate 6 is more stably adhered to the suction cup 21.
[0074] 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.
