Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a dust removal component. Background Technology

[0002] During battery production, battery components such as electrodes and tabs undergo multiple processing steps. During these steps, dust is generated due to wear, cutting, scraping, and coating. If this dust adheres to the material surface, it can cause contamination. Therefore, it is necessary to clean up dust and other contaminants generated during production to prevent them from affecting material quality and thus reducing battery quality.

[0003] A common dust removal method involves blowing air onto the surface of materials through air pipes. In cases involving large dust removal areas or multi-zone dust removal, multiple air pipes are needed to increase the dust removal area or achieve multi-zone dust removal. Air supply methods for multiple air pipes include individual air supply and centralized air supply. Individual air supply refers to setting up separate air supply pipes for each of the multiple air pipes, which increases equipment cost and complicates the equipment structure. Centralized air supply involves setting up a single air supply pipe that connects to multiple air pipes simultaneously; however, this method results in inconsistent blowing pressure among the multiple air pipes connected to the same supply pipe, leading to inconsistent dust removal effects in different areas. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a dust removal component to solve the problem that the existing method of supplying air to multiple air pipes cannot simultaneously achieve dust removal effect and equipment cost.

[0005] To achieve the above technical objectives, this application provides a dust removal assembly, comprising: an air supply pipe and multiple air blowing pipes connected to the air supply pipe;

[0006] The air supply pipe is used to supply air to the air blowing pipe;

[0007] The angle between the air inlet direction of the air blowing pipe and the air delivery direction of the air delivery pipe is an acute angle.

[0008] Furthermore, it includes: flow guides;

[0009] The flow guide is disposed at the air outlet of the air blowing pipe;

[0010] The flow guide is provided with a flow guide groove that connects to the air blowing pipe;

[0011] The dimensions of the guide channel in the first direction decrease along the air supply direction, so that the air outlet of the guide channel forms a flat opening structure.

[0012] Furthermore, the dimension of the guide channel in the second direction is expanded along the air delivery direction so that the guide channel forms a funnel-shaped structure, wherein the second direction is perpendicular to the first direction.

[0013] Furthermore, the flow guide is provided with a plurality of flow guide grooves;

[0014] The air blowing pipe includes multiple parts;

[0015] The flow guide groove is connected to the air blowing pipe in a one-to-one correspondence.

[0016] Furthermore, multiple of the aforementioned guide channels are arranged along the second direction.

[0017] Furthermore, this includes dust collection ports;

[0018] The dust removal port is nested within the flow guide, and the dust removal port can be detached from the flow guide.

[0019] Furthermore, an air valve is provided on the air blowing pipe;

[0020] The air valve is used to control the air flow rate of the air blowing pipe.

[0021] Furthermore, the air valve includes: a valve body and a switch;

[0022] The valve body is disposed inside the air blowing pipe, and a support shaft is provided on the valve body;

[0023] The support shaft is rotatably connected to the air blowing pipe;

[0024] The switch is connected to the support shaft, and the switch is used to drive the valve body to rotate in order to adjust the size of the gap between the valve body and the air blowing pipe.

[0025] Furthermore, the air valve includes an indicator;

[0026] The switch is equipped with a scale.

[0027] The indicator is fixedly connected to the air blowing tube, and the indicator is disposed on the outer periphery of the scale.

[0028] Furthermore, it includes: adjustment components;

[0029] The adjustment component is connected to the air delivery pipe and is used to move the air delivery pipe and the air blowing pipe closer to or away from the material.

[0030] As can be seen from the above technical solutions, this application provides a dust removal component, including: an air supply pipe and multiple air blowing pipes connected to the air supply pipe; the air supply pipe is used to supply air to the air blowing pipes; the angle between the air blowing pipes and the air supply pipes is an acute angle, and the air blowing pipes face the air inlet direction of the air supply pipes. This can reduce the resistance pressure during the process of the airflow from the air supply pipes entering the air blowing pipes, and facilitate the airflow in the air supply pipes to enter the air blowing pipes, thereby increasing the consistency of the airflow pressure in each air blowing pipe, and thus increasing the consistency of the dust removal effect of each air blowing pipe.

[0031] This solution eliminates the need for separate air supply pipes for each air blowing pipe, simplifying the equipment and reducing costs, while maintaining consistent dust removal performance across multiple air blowing pipes and further reducing equipment costs. Attached Figure Description

Detailed Implementation

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments in this application specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application.

[0045] In the description of the embodiments of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application 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 the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0047] Please see Figure 1This application provides a dust removal component, comprising: an air supply pipe 10 and a plurality of air blowing pipes 20 connected to the air supply pipe 10. The air supply pipe 10 is used to supply air to the air blowing pipes 20. The air supply pipe 10 can be connected to an air supply system or other equipment capable of supplying air externally, and then the airflow is delivered to the air blowing pipes 20. The air outlet of the air blowing pipes 20 is configured to face the material to achieve air blowing dust removal from the material. The material can be an electrode sheet, electrode tab, etc. The end of the air blowing pipe 20 away from the air supply pipe 10 is the air outlet of the air blowing pipe 20, and the end of the air blowing pipe 20 closer to the air supply pipe 10 is the air inlet of the air blowing pipe 20.

[0048] In this embodiment, the angle α between the air inlet direction of the air blowing pipe 20 and the air delivery direction of the air delivery pipe 10 is an acute angle.

[0049] Specifically, such as Figure 1 As shown, the air supply direction of the air supply pipe 10 is... Figure 1 The direction indicated by arrow 1 in the diagram; the air intake direction of the air blowing pipe 20 is the air intake direction of the air inlet of the air blowing pipe 20, and also... Figure 1 The direction indicated by the middle arrow 2.

[0050] In practical applications, the air delivery direction within the air delivery pipe 10 is generally the axial direction of the air delivery pipe 10. Similarly, the air intake direction of the blowing pipe 20 refers to the axial direction of the section of the blowing pipe 20 closest to the air inlet.

[0051] like Figure 2 As shown, when the section of the blowing pipe 20 near the air inlet is perpendicular to the air delivery pipe 10, the included angle α is a right angle; when the section of the blowing pipe 20 near the air inlet is opposite to the air delivery direction, the included angle α is an obtuse angle.

[0052] Compared to Figure 2 In this embodiment, the included angle α is an acute angle, which can reduce the resistance pressure of the gas in the air supply pipe 10 entering the air blowing pipe 20. This makes it easier for the airflow in the air supply pipe 10 to enter the air blowing pipe 20, avoiding the problem of inconsistent dust removal effect caused by inconsistent air intake of multiple air blowing pipes 20.

[0053] It should be noted that when the air supply pipe 10 has a bent structure and multiple air supply directions, the angle α between the air intake direction of the blowing pipe 20 and the air supply direction of the air supply pipe 10 refers to the angle at the junction of the blowing pipe 20 and the air supply pipe 10. Specifically, as... Figure 3 As shown, when there is a bend in the air supply pipe 10, the air supply direction of different pipe sections is inconsistent. For example, when there is an arc section in the air supply pipe 10, the air supply direction at any point is the tangent direction at that point. When there are multiple air supply directions in the air supply pipe 10, the included angle α is the included angle between two directions at the junction of the blowing pipe 20 and the air supply pipe 10.

[0054] As one implementation method, such as Figure 3 As shown, the air blowing pipes 20 can be arranged at intervals along the air delivery direction of the air supply pipe 10 and oriented in different directions, so that different air blowing pipes 20 can blow air to remove dust in different areas.

[0055] As one implementation method, such as Figure 1 As shown, multiple air blowing pipes 20 can be arranged sequentially along the air supply direction of the air supply pipe 10 and in the same orientation, so that multiple air blowing pipes 20 can blow air to remove dust in the same direction, and the multiple air blowing pipes 20 can increase the blowing volume and expand the blowing area.

[0056] In one embodiment, please refer to Figure 4 and Figure 5 The dust removal component includes: a flow guide 30; the flow guide 30 is disposed at the air outlet of the air blowing pipe 20; the flow guide 30 is provided with a flow guide groove 31 that communicates with the air blowing pipe 20; the size of the flow guide groove 31 in the first direction a decreases along the air delivery direction so that the air outlet of the flow guide groove 31 forms a flat opening structure.

[0057] The guide element 30 guides the gas blown out by the air blowing pipe 20. In practical applications, it can guide the gas towards the material. Taking the air blowing pipe 20 blowing in a horizontal direction as an example, the guide groove 31 can be configured as a flat-mouth structure with the length direction horizontal. The guide groove 31 can increase the airflow pressure of the air blowing pipe 20, thereby improving the dust removal effect.

[0058] As a further improvement, the dimension of the guide groove 31 in the second direction b is enlarged along the air delivery direction so that the guide groove 31 forms a funnel-shaped structure, wherein the second direction b is perpendicular to the first direction a.

[0059] In practical applications, the second direction b can be the length direction of the flat-mouthed guide channel 31. Configuring the guide channel 31 as a flared structure can increase the air blowing area in the second direction b.

[0060] In one embodiment, corresponding to the structure of multiple air blowing pipes 20, the guide member 30 is provided with multiple guide grooves 31; the guide grooves 31 are connected one-to-one with the air blowing pipes 20. That is, in this embodiment, one guide member 30 can be installed on multiple air blowing pipes 20 at the same time to simplify the assembly of the equipment.

[0061] As an improvement, multiple guide channels 31 are arranged along the second direction b, that is, along the length of the air outlet of the guide channel 31, so that the multiple guide channels 31 can form a long strip-shaped air outlet structure, which can be adapted to areas with large dust removal areas.

[0062] In applications, such as Figure 6As shown, multiple guide channels 31 are configured to abut against each other sequentially along their length, so that the multiple guide channels 31 can form a continuous elongated air outlet structure.

[0063] In one embodiment, see Figure 7 The dust removal assembly also includes a dust removal port 40; the dust removal port 40 is nested in the flow guide 30, and the dust removal port 40 can be detached from the flow guide 30.

[0064] The dust removal port 40 can serve as a confluence for the multiple guide grooves 31 on the guide component 30, thereby forming an integrated air outlet.

[0065] In one embodiment, see Figure 1 and Figure 8 An air valve 50 is provided on the air blowing pipe 20; the air valve 50 is used to control the air flow rate of the air blowing pipe 20.

[0066] The air valve 50 can control the air flow of each air blowing pipe 20 and notify the opening and closing of each air blowing pipe 20, so that the air blowing pipes 20 that are not in use can be closed to control the overall dust removal area of ​​the dust removal assembly.

[0067] In practical applications, taking a conveyor belt with the material being dusted as the electrode as an example, multiple air blowing pipes 20 can be arranged above the conveyor belt along its width direction, thereby achieving comprehensive dust removal during transportation. By controlling the opening and closing of the air blowing pipes 20 through the air valve 50, the dust removal component can be adapted to conveyor belts of different widths, improving the applicability of the equipment.

[0068] As one implementation method, each air blowing pipe 20 can be equipped with an air flow sensor. The air flow sensor can detect the gas flow rate inside each air blowing pipe 20, making it easier for operators to control the air valve 50.

[0069] In one implementation, the air valve 50 can be an electrically controlled valve. The air valve 50 and each air flow sensor are connected to a processor. The processor can acquire the gas flow value of each air pipe 20 and control the opening and closing of each air valve 50, as well as the opening range.

[0070] In one embodiment provided in this application, please refer to Figure 8 The air valve 50 includes a valve body 51 and a switch 53. The valve body 51 is disposed inside the air blowing pipe 20, and a support shaft 52 is provided on the valve body 51. The support shaft 52 is rotatably connected to the air blowing pipe 20. The switch 53 is disposed outside the air blowing pipe 20 and is connected to the support shaft 52. The switch 53 is used to drive the valve body 51 to rotate to adjust the size of the gap between the valve body 51 and the air blowing pipe 20.

[0071] The valve body 51 can be a circular disc structure. When the valve body 51 rotates around the axis of the support shaft 52 to be parallel to the radial direction of the air blowing pipe 20, the valve body 51 can close the air blowing pipe 20. When the valve body 51 rotates around the axis of the support shaft 52 to be parallel to the axial direction of the air blowing pipe 20, the opening range of the air valve 50 is at its maximum.

[0072] The valve body 51 can be manually rotated around the axis of the support shaft 52 via switch 53. In application, switch 53 can be manually controlled by an operator or connected to an electrically controlled drive device for automated control. The electrically controlled drive device can be, for example, a rotary motor. The output of the rotary motor is connected to switch 53 via gears or other transmission components to drive the switch to rotate.

[0073] In one embodiment, the air valve 50 includes an indicator 54; the switch 53 is provided with a scale 55; the indicator 54 is fixedly connected to the air pipe 20, and the indicator 54 is disposed on the outer periphery of the scale 55.

[0074] Staff can determine the opening degree of the air tube 20 by observing the correspondence between indicator 54 and scale 55. In practical applications, scale 55 can be equipped with Chinese characters such as "open" and "close" as indicator symbols.

[0075] In one implementation, the scale 55 can be set on the dial provided on the switch 53. The indicator 54 can be provided with a pointer that extends into the dial, making it easy for the operator to identify the correspondence between the indicator 54 and the scale 55.

[0076] In one embodiment, an arc-shaped guide groove 56 may be provided on the switch 53; specifically, the arc-shaped guide groove 56 may be provided on the aforementioned dial. The indicator 54 is provided in the arc-shaped guide groove 56, and during the rotation of the switch 53, the cooperation between the indicator 54 and the arc-shaped guide groove 56 can guide the switch 53.

[0077] In one embodiment, see Figure 7 The dust removal assembly also includes: an adjustment component 60; the adjustment component 60 is connected to the air supply pipe 10 and is used to move the air supply pipe 10 and the air blowing pipe 20 closer to or away from the material.

[0078] Specifically, the adjustment assembly 60 may include a slide rail and a linear actuator. The linear actuator may be, for example, a cylinder. The air delivery pipe 10 is mounted on the slide rail; the output end of the linear actuator is connected to the air delivery pipe 10, enabling the linear actuator to drive the air delivery pipe 10 to slide linearly. In practical applications, the linear actuator driving the air delivery pipe 10 to slide linearly can control the air blowing pipe 20 to move closer to or further away from the material, thereby adjusting the distance between the air blowing pipe 20 and the material.

[0079] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features.
