Description

Technical Field

[0001] This utility model relates to the field of lithium battery manufacturing, and in particular to a dust removal and collection device. Background Technology

[0002] During lithium battery production, laser cutting machines, winding machines, and hot pressing machines generate a large amount of dust and debris due to electrode cutting and core transfer processes. If this dust and debris is not removed in time, it can easily adhere to the surface of the electrodes or cores, leading to quality problems such as short circuits, increased self-discharge, and capacity decay. The traditional solution is to lay an adhesive mat underneath the machine to absorb the dust and debris through its surface adhesion. However, this solution suffers from frequent manual intervention, inconsistent cleaning results, and dust and debris splashing when the contaminated layer of the adhesive mat is removed.

[0003] To address these issues, the industry has attempted to add a vacuuming device under the adhesive pad. However, since the adhesive pad is statically attached, the dust still needs to be manually removed before it can be sucked in, thus failing to achieve truly automated cleaning. Utility Model Content

[0004] The purpose of this utility model is to provide a dust removal and collection device. By setting a dust removal component below the dust sticking component, the reciprocating brush in the dust removal component can completely remove the dust on the dust sticking roller. Then, the dust collection component and negative pressure equipment collect and process the dust, resulting in a higher degree of cleaning automation and a significant improvement in cleaning effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model discloses a dust removal and collection device, including a dust-adhesive component, a dust-cleaning component disposed below the dust-adhesive component, a dust-collecting component disposed below the dust-cleaning component, a dust removal pipe connected to the dust-collecting component, and a suction fan connected to the end of the dust removal pipe; wherein, the dust-cleaning component includes a brush drive roller, a brush disposed on the surface of the brush drive roller, and a power unit for driving the brush drive roller to move horizontally.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.

[0024] Please see Figure 1-3 In this embodiment, a dust removal and collection device includes a dust-adhesive assembly 1, a dust-removing assembly 2 disposed below the dust-adhesive assembly 1, a dust-collecting assembly 3 disposed below the dust-removing assembly 2, a dust-collecting pipe 4 connected to the dust-collecting assembly 3, and a suction fan 5 connected to the other end of the dust-collecting pipe 4. The dust-removing assembly 2 includes a brush drive roller 21, a brush 22 disposed on the surface of the brush drive roller 21, and a power unit 23 that drives the brush drive roller 21 to move horizontally. Compared to traditional dust-adhesive pads, the dust-removing assembly 2 achieves automated cleaning, reduces manual intervention, and can be used continuously. The brush 22 moves horizontally back and forth below the plane formed by the dust-adhesive assembly 1, forming a "line-surface combined" cleaning mode. The power unit drives the brush 22 to reciprocate, sweeping across the entire circumferential surface of the dust-adhesive roller 11, ensuring that all adhered dust is removed and avoiding cleaning blind spots.

[0025] Furthermore, the power unit 23 includes a first conveyor belt 231 located on the outer periphery of the brush drive roller 21 and a first motor 232 that drives the first conveyor belt 231 to rotate in the forward or reverse direction. Through preset forward and reverse rotation, the motor drives the brush 22 to perform reciprocating motion in the horizontal direction.

[0026] Furthermore, the adhesive assembly 1 includes multiple parallel adhesive rollers 11, a second conveyor belt 12 located at both ends of the adhesive rollers 11, and a second motor 13 that drives the second conveyor belt 12 to rotate. The adhesive rollers 1 are made of silicone or rubber. The second conveyor belt 12 is driven to rotate by the second motor 13, and the friction between the ends of the adhesive rollers 11 and the second conveyor belt 12 causes the adhesive rollers 11 to rotate in the same direction.

[0027] Furthermore, the dust-adhesive roller 11 and the brush drive roller 21 are arranged perpendicularly. The vertical design of the two allows the brush 22 to make more comprehensive contact with the surface of the dust-adhesive roller 11. When the brush 22 moves back and forth, it can clean the dust-adhesive roller 11 more thoroughly and avoid the residue of foreign objects such as powder. In addition, this vertical arrangement helps to guide the cleaned-off foreign objects such as powder into the first dust collection box 31 in a timely manner.

[0028] Furthermore, the dust collection assembly 3 includes a first dust collection box 31, a dust collection funnel 32, and a second dust collection box 33 connected in sequence from top to bottom; the second dust collection box 33 is connected to the dust removal pipe 4. Through the graded design of the first dust collection box 31 and the second dust collection box 33, and the intermediate transition provided by the dust collection funnel 32, pipe blockage caused by excessive dust is avoided.

[0029] Furthermore, there are multiple dust collection funnels 32 arranged in an array below the dust collection assembly 11, which more comprehensively covers the area of ​​the first integrated box 31, so that the dust falling from the dust collection roller 11 and the brush 22 can be effectively collected, reducing leakage.

[0030] Furthermore, the dust collection funnel 32 has a conical structure that is smaller at the top and larger at the bottom. This design prevents dust from clogging the funnel and reduces the failure rate.

[0031] Furthermore, the brush drive roller 21 is a bearing structure, with its outer ring not rotating and its inner shaft rotating. The friction between the inner shaft and the first conveyor belt 231 drives the inner shaft to rotate, thereby changing the horizontal displacement of the brush 22. The outer ring does not rotate, ensuring that the brush 22 is always located at the top of the drive roller and remains in contact with the dust-adhesive roller 11.

[0032] In other embodiments, the brush drive roller 21 is a solid roller, and the brushes 22 are arranged around the brush drive roller 21 and rotate synchronously with the rotation of the brush drive roller 21.

[0033] Furthermore, the device also includes a dust collection box 6 connected to the suction fan 5. The dust collected by the second dust collection box 33 is finally placed into the dust collection box 6 under the action of the suction fan 5, which facilitates centralized classification and processing of the dust. The dust collection box 6 has a large capacity and is located at the end of the system, so the maintenance frequency is relatively low, and it only needs to be cleaned and replaced periodically.

[0034] In operation, the second motor drives the second conveyor belt, which, under the action of friction, causes all parallel dust-adhesive rollers 11 to rotate in the same direction. Due to the material of the dust-adhesive rollers 11, they adsorb the powder and debris on the core or electrode sheet and rotate accordingly. When they reach the lowest end of the dust-adhesive roller 11, they come into contact with the brush 22. The brush drive roller 21 moves horizontally back and forth under the action of the first motor 232. The brush 22 evenly sweeps the powder and debris adsorbed on each dust-adhesive roller 11 from one end to the other. The powder and debris fall freely into the first dust collection box 31. Under the negative pressure of the suction fan 5, the powder and debris fall sequentially into the dust collection funnel 32 and the second dust collection box 33, enter the dust removal pipe 4, and are finally collected in the dust storage box 6 for centralized processing. Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0035] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
