Description

Technical Field

[0001] This invention relates to the field of power battery technology, and more specifically, to an electrode dust removal device and an electrode dust removal system. Background Technology

[0002] In the production process of lithium-ion power batteries, the stacking process is a crucial step in transporting and stacking die-cut electrode sheets into battery cells via belt conveyor. Dust often remains on the surface of the electrode sheets after die-cutting. This dust not only affects battery performance but may also pose a short-circuit risk during subsequent stacking processes. To remove dust from the electrode surface, the current industry-standard electrode dust removal solution is based on the synergistic effect of blowing and suction. Specifically, the dust removal fixture is located above the electrode conveying path. Its built-in blowing component generates a high-speed airflow to disperse dust from the electrode surface, while the suction component captures and removes the dust carried away by the airflow.

[0003] However, significant challenges arose in actual operation. The setting of the blowing pressure was particularly critical; too low a pressure was insufficient to completely remove dust, while too high a pressure could cause the electrode sheets to shift during conveyor belt transport, affecting the accuracy of subsequent lamination and the quality of the cells. To prevent electrode shifting, traditional methods often involved raising the fixture to increase the distance between the dust removal fixture and the electrode sheets, or lowering the blowing speed. However, both of these methods directly reduced the efficiency of the dust removal fixture, severely impacting its dust removal effect and resulting in poor dust collection. Summary of the Invention

[0004] The main objective of this invention is to provide an electrode dust removal device and system that can solve the problem that existing dust removal devices require increasing the distance between the dust removal fixture and the electrode or reducing the blowing speed in order to ensure dust removal effect while preventing the electrode from shifting during the conveying process, resulting in poor dust removal effect.

[0005] To achieve the above objectives, according to one aspect of the present invention, an electrode dust removal device is provided, comprising: a blowing assembly including a base, the base having a first outlet and a plurality of first outlets, a portion of the plurality of first outlets being arranged at intervals along a first direction to form a first branch, and another portion being arranged at intervals along a second direction to form a second branch, the first branch and the second branch forming an outward expansion structure; a flow guiding structure mounted on the base, the flow guiding structure being disposed corresponding to the first outlet and located on the outlet side of the first outlet, the flow guiding structure and the outward expansion structure being arranged sequentially along a third direction, the flow guiding structure being located at the starting end of the outward expansion structure, along a fourth direction, the first branch and the second branch being located on opposite sides of the flow guiding structure, the flow guiding structure being capable of changing the flow direction of the airflow blown out from the first outlet to form an airflow flowing along the fourth direction.

[0006] With the above settings, the electrode can be firmly pressed onto the conveyor belt during the electrode conveying process, avoiding vibration and displacement of the electrode during conveying. Therefore, there is no need to increase the distance between the dust removal tool and the electrode or reduce the blowing speed, thereby improving the dust removal effect of the dust removal tool.

[0007] Furthermore, the flow guiding structure extends in a third direction, with the end of the flow guiding structure away from the outward expansion structure protruding from the base. Both ends of the flow guiding structure are spherical structures, and the middle part of the flow guiding structure is a cylindrical structure.

[0008] With the above configuration, the end of the flow guide structure away from the outward expansion structure protrudes from the base. When installing the electrode dust removal device on the conveying device, the installation direction can be distinguished based on the part of the flow guide structure protruding from the base, ensuring that the side where the flow guide structure is located is the first end of the electrode dust removal device. That is, the electrode passes through the flow guide structure first and then sequentially through the first air outlet, thus preventing the electrode dust removal device from being installed backwards. The middle part of the flow guide structure is a cylindrical structure, which is positioned corresponding to the electrode. The central axis of the cylindrical structure extends along a third direction. According to the Coanda effect (when a fluid flows over a non-planar solid surface, the fluid tends to adhere to this surface, i.e., the fluid flows along the shape of the surface), the airflow blown from the first outlet flows along the surface of the cylindrical structure, thereby forming an airflow flowing in a fourth direction. This airflow gradually presses down on the electrode from one end to the other along the fourth direction, avoiding the upward lifting effect caused by the vertical impact of the airflow, thus eliminating the vibration and displacement of the electrode.

[0009] Furthermore, the outlet is positioned corresponding to the middle of the flow guide structure, with the middle of the flow guide structure located on the outlet side of the outlet.

[0010] With the above setup, when the high-speed airflow is ejected from the first outlet, it flows along the cylindrical surface, forming a downward airflow that effectively presses the electrode sheet onto the conveyor belt.

[0011] Furthermore, there are at least two first-outlet air ports, which extend along a third direction and along a fourth direction, with at least one first-outlet air port provided on each of the opposite sides of the flow guiding structure.

[0012] The above settings help maintain the stability of the electrode on the conveyor belt and prevent the electrode from vibrating due to the impact of airflow on one side.

[0013] Furthermore, the third part of the multiple first air outlets is arranged at intervals along the third direction to form a third branch. The third branch is located between the first branch and the second branch, and the flow guiding structure is collinear with the third branch.

[0014] The above settings allow the center of the electrode to be subjected to the pressure of the airflow from top to bottom, enhancing the stability of the electrode's movement during transport.

[0015] Furthermore, the first branch and the second branch are arranged symmetrically about the third branch; and / or, the first branch, the second branch, and the third branch form an arrowhead-shaped structure.

[0016] With the above configuration, the first and second branches are symmetrically arranged about the third branch, ensuring equal airflow pressure on both sides of the electrode and preventing electrode tilting or warping due to uneven airflow. This uniformity is crucial for maintaining the flatness of the electrode during transport, improving the consistency and reliability of dust removal. Furthermore, the symmetrically distributed first air outlet creates a uniform pressure distribution on the electrode, helping to stabilize its position and reduce vibration during transport. The first, second, and third branches form an arrowhead-shaped structure, creating an airflow that gradually diffuses from the center outwards, ensuring airflow covers the entire surface of the electrode. This improves dust removal efficiency and prevents electrode displacement.

[0017] Furthermore, the first branch includes a first branch and a second branch that are parallel to each other. The second branch is located between the first branch and the third branch. The multiple first air outlets forming the first branch and the multiple first air outlets forming the second branch are arranged alternately and staggered along the first direction.

[0018] The above settings ensure that the airflow is evenly distributed on the electrode. Furthermore, since the airflow does not act simultaneously on the same location of the electrode, but rather diffuses gradually, it can prevent the electrode from vibrating due to airflow impact.

[0019] Furthermore, the electrode dust removal device also includes a dust collection component, which is used to remove dust from the electrode. The base is also provided with multiple first dust collection ports. Along the third direction, the multiple first dust collection ports and the multiple first air outlets forming the third branch are arranged alternately, and the multiple first dust collection ports and the multiple first air outlets forming the third branch all extend along the third direction. The dust collection component can perform dust collection through the first dust collection ports.

[0020] The above settings enable the blowing and dust collection processes to work together more effectively. When the first air outlet of the third branch blows the dust on the electrode, the adjacent first dust collection port can immediately suck up the dust, preventing the dust from being deposited again on the electrode surface or spreading into the surrounding environment, thus improving the immediate efficiency and cleanliness of dust removal.

[0021] Furthermore, the electrode dust removal device also includes a dust collection component, which is used to remove dust from the electrode. The base is also provided with multiple second dust collection ports, which extend along the fourth direction and are perpendicular to the third direction. The multiple second dust collection ports are all located on the side of the flow guiding structure facing the outward expansion structure. Along the fourth direction, the multiple second dust collection ports are symmetrically distributed on opposite sides of the third branch. The dust collection component can perform dust collection through the second dust collection ports.

[0022] The above settings can effectively capture dust that is blown up during the purging process but is not immediately absorbed by the first suction port, reducing the possibility of dust escaping into the surrounding environment, and thus ensuring that the electrode is thoroughly cleaned when passing through the electrode dust removal device.

[0023] Furthermore, a gas flow channel is provided on the base. The air inlet end of the gas flow channel is configured to be connected to the air supply device. Multiple first air outlets are connected to the gas flow channel. The gas flow channel includes a first flow channel and a second flow channel. Multiple first air outlets forming the second branch are connected to the first flow channel, and multiple first air outlets forming the first branch are connected to the second flow channel.

[0024] The above settings allow for independent control of the airflow in the first and second branches. The airflow pressure and flow rate of the first and second channels can be adjusted according to the surface conditions of different areas of the electrode, enabling personalized dust removal for different parts of the electrode and improving the accuracy and flexibility of dust removal.

[0025] Furthermore, the first flow channel includes a first main flow channel and multiple first branch flow channels. The first main flow channel extends along a second direction, and the multiple first branch flow channels are all connected to the first main flow channel. The multiple first branch flow channels are connected to the multiple first air outlets that form the second branch. The second flow channel includes a second main flow channel and multiple second branch flow channels. The second main flow channel extends along a first direction, and the multiple second branch flow channels are all connected to the second main flow channel. The multiple second branch flow channels are connected to the multiple first air outlets that form the first branch.

[0026] The above configuration enables precise airflow distribution. The first and second main flow channels guide the primary direction of airflow, while the first and second branch flow channels distribute the airflow to their corresponding first outlets. Each first branch flow channel corresponds one-to-one with a plurality of first outlets forming a second branch, and each second branch flow channel corresponds one-to-one with a plurality of first outlets forming a first branch, ensuring uniform airflow distribution on the electrode surface.

[0027] Furthermore, the cross-section of the first main channel gradually decreases along its extension direction, and the cross-section of the second main channel gradually decreases along its extension direction.

[0028] With the above settings, on the one hand, the blowing resistance can be increased to ensure the uniformity of the flow at the first outlet. On the other hand, since the airflow speed naturally increases in the narrower flow channel, the energy consumption to maintain the required airflow speed can be reduced, thereby improving the energy efficiency ratio of the entire device.

[0029] Furthermore, the first flow channel also includes a third branch flow channel connected to the first main flow channel, and the outlet end of the third branch flow channel is connected to the first outlet of the first part forming the third branch. The second flow channel also includes a fourth branch flow channel connected to the second main flow channel, and the outlet end of the fourth branch flow channel is connected to the first outlet of the second part forming the third branch.

[0030] With the above settings, air can be supplied to the first air outlet of the third branch.

[0031] Furthermore, the electrode dust removal device also includes an air conveying section installed on the base. The air inlet of the air conveying section is configured to be connected to the air supply device. The air outlet, multiple first air outlets, and the air inlet of the gas flow channel are all connected to the air outlet of the air conveying section. The air conveying section includes an air storage body and at least one first connector installed on the air storage body. The air storage body has at least one air storage chamber. The air inlet of the first connector is configured to be connected to the air supply device. The first connector is correspondingly arranged with the air storage chamber. The air outlet of the first connector is connected to the air storage chamber. The first flow channel and the second flow channel are both connected to the corresponding air storage chamber.

[0032] With the above setup, the air storage chamber can serve as a buffer for airflow. After being connected to the air supply device through the first connector, it can stably receive and store compressed air, which helps to maintain the stability of airflow when the air supply is unstable or the air pressure fluctuates, ensures the uniform output of airflow pressure, and improves the consistency of dust removal effect.

[0033] Furthermore, the electrode dust removal device also includes an adjustment mechanism, which includes two connecting parts. Along the fourth direction, the conveying device has a first side and a second side arranged opposite to each other. One of the two connecting parts is configured to be installed on the first side, and the other of the two connecting parts is configured to be installed on the second side. Each of the two connecting parts is provided with at least one moving part. The moving part is movably arranged on the corresponding connecting part in the vertical direction. The moving part is provided with a slot. Along the fourth direction, at least one sliding part is provided on each of the opposite sides of the base. At least one moving part and at least one sliding part are arranged in a one-to-one correspondence. The end of the sliding part away from the base passes through the corresponding slot and can slide in the slot along the fourth direction.

[0034] With the above settings, the position of the electrode dust removal device can be adjusted in the vertical direction, thereby adjusting the distance between the first and second air outlets and the electrode, and the position of the electrode dust removal device can also be adjusted in the fourth direction.

[0035] According to another aspect of the present invention, an electrode dust removal system is provided, comprising: a conveying device; and an electrode dust removal device as described above, wherein the electrode dust removal device is mounted on the conveying device.

[0036] The present invention employs a blowing assembly, a guiding structure, and a dust collection assembly. When the electrode sheet is conveyed to the electrode sheet dust removal device via a conveyor belt, it first passes through the guiding structure and the first outlet air port. Since the guiding structure is located on the outlet side of the first outlet air port, the gas blown out from the outlet side of the first outlet air port will pass through the guiding structure. The guiding structure can change the flow direction of the airflow blown out from the first outlet air port, so that the airflow blown out from the first outlet air port from top to bottom becomes an airflow flowing along the fourth direction, and gradually blown from one end of the upper surface of the electrode sheet to the other end of the upper surface of the electrode sheet along the fourth direction. That is, the airflow with the changed flow direction by the guiding structure gradually presses the electrode sheet from one end of the electrode sheet to the other end of the electrode sheet along the fourth direction. This gradual airflow avoids the instantaneous large-area impact on the electrode sheet and avoids the upward lifting effect caused by the vertical impact of the airflow, thereby eliminating the vibration and displacement of the electrode sheet. The electrode continues to move along the third direction. After exiting the area where the guide structure is located, the electrode then passes through multiple first air outlets in sequence. Because the first and second branches form an outward-expanding structure, the airflow diffusion range gradually increases along the third direction, creating an airflow that gradually expands outwards. This type of airflow, as the electrode moves along the third direction, gradually presses it down. Furthermore, this type of airflow only blows onto a portion of the electrode area, without immediately covering it, thus eliminating vibration and displacement. As can be seen from the above, the combination of the guide structure and the outward-expanding structure ensures that the electrode is firmly pressed onto the conveyor belt during transport, preventing vibration and displacement. Therefore, there is no need to increase the distance between the dust collection equipment and the electrode or reduce the blowing speed, thereby improving the dust collection effect of the dust collection equipment.

[0056] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0057] See also Figures 1 to 8 as well as Figure 14 As shown, the present invention provides an electrode dust removal device 60, which includes: a blowing assembly including a base 11, on which a first outlet 90 and a plurality of first outlets 15 are provided, a portion of the plurality of first outlets 15 are arranged at intervals along a first direction to form a first branch 17, and another portion are arranged at intervals along a second direction to form a second branch 80, the first branch 17 and the second branch 80 forming an outward expansion structure; a flow guiding structure 20, installed on the base 11, the flow guiding structure 20 is provided corresponding to the first outlet 90 and located on the outlet side of the first outlet 90, the flow guiding structure 20 and the outward expansion structure are arranged sequentially along a third direction, the flow guiding structure 20 is located at the starting end of the outward expansion structure along a fourth direction, the first branch 17 and the second branch 80 are located on opposite sides of the flow guiding structure 20, the flow guiding structure 20 can change the flow direction of the airflow blown out from the first outlet to form an airflow flowing along the fourth direction.

[0058] In this embodiment, the third direction refers to the conveying direction of the electrode 70. The fourth direction is perpendicular to the third direction. The first branch and the second branch forming an outward expansion structure means that the first branch and the second branch are set at an angle, and the first branch and the second branch together form a structure similar to a less-than sign (“<”). The guide structure being located at the starting end of the outward expansion structure means that the guide structure is located at the starting point where the outward expansion structure begins, equivalent to the guide structure being set on the tip side of the less-than sign (“<”). The guide structure and the outward expansion structure are arranged sequentially along the third direction; that is, during the dust removal process, the electrode first passes through the guide structure and then through the outward expansion structure.

[0059] The flow guiding structure is located at the bottom of the base and protrudes towards the side where the electrode is located. In other words, the flow guiding structure is closer to the electrode than the base. Since the flow guiding structure is corresponding to the first outlet air port, when the electrode 70 is conveyed to the electrode dust removal device 60 by the conveyor belt 52, it first passes through the flow guiding structure 20 and the first outlet air port. Because the flow guiding structure is located on the outlet side of the first outlet air port 90, the gas blown out from the outlet side of the first outlet air port will pass through the flow guiding structure. The flow guiding structure 20 can change the flow direction of the airflow blown out from the first outlet air port, so that the airflow blown out from the first outlet air port from top to bottom becomes an airflow flowing in the fourth direction, and gradually blows from one end of the upper surface of the electrode to the other end of the upper surface of the electrode along the fourth direction. That is, the airflow whose flow direction is changed by the flow guiding structure gradually presses the electrode from one end of the electrode to the other end along the fourth direction. This gradual airflow avoids the instantaneous large-area impact on the electrode and avoids the upward lifting effect caused by the vertical impact of the airflow, thereby eliminating the vibration and displacement of the electrode.

[0060] The electrode 70 continues to move along the third direction. After exiting the area where the guide structure 20 is located, the electrode 70 then passes through multiple first air outlets 15 in sequence. Due to the outward expansion structure formed by the first and second branches, the diffusion range of the airflow gradually increases along the third direction, forming an airflow that gradually expands along the third direction. This type of airflow can gradually press the electrode 70 down as it moves along the third direction. Moreover, this type of airflow only blows onto a portion of the electrode area and does not immediately cover the electrode, thus eliminating the vibration and displacement of the electrode. As can be seen from the above, the combination of the guide structure and the outward expansion structure ensures that the electrode is firmly pressed onto the conveyor belt during the electrode conveying process, preventing the electrode 70 from vibrating and shifting during conveying. Therefore, there is no need to increase the distance between the dust removal fixture and the electrode or reduce the blowing speed, thereby improving the dust removal effect of the dust removal fixture.

[0061] It should be noted that the first air outlet 15 and the first air outlet 90 in this application can both be connected to an external air supply device. The air supply device is used to provide gas (e.g., compressed air or other feasible gas). The gas is blown from the first air outlet 15 and the first air outlet 90 toward the electrode 70, which can both press down the electrode 70 and blow up the dust on the electrode 70.

[0062] The electrode dust removal device 60 of this application removes dust from the electrode 70 after die-cutting during the stacking process of lithium-ion battery manufacturing. In the stacking process, die-cutting cuts the electrode 70 into continuous sheet-like electrode sheets 70, which are then conveyed on a conveyor belt by negative pressure suction. The common method for removing dust from the electrode 70 on the conveyor belt is not very efficient, and excessive wind speed may cause the electrode 70 to deviate, affecting subsequent CCD positioning and gripping. The electrode dust removal device 60 of this application has the advantages of simple structure, low cost, and high dust removal efficiency, and can ensure that the electrode 70 does not deviate during the conveying process, thus ensuring both dust removal effect and not affecting subsequent CCD positioning and gripping.

[0063] See also Figures 1 to 9 As shown, in one embodiment of the present invention, the flow guiding structure 20 extends along a third direction, the end of the flow guiding structure 20 away from the outward expansion structure protrudes from the base 11, both ends of the flow guiding structure 20 are spherical structures, and the middle part of the flow guiding structure 20 is a cylindrical structure.

[0064] In this embodiment, the end of the flow guiding structure 20 away from the expansion structure protrudes from the base 11. When the electrode dust removal device 60 is installed on the conveying device 50, the installation direction can be distinguished according to the part of the flow guiding structure 20 that protrudes from the base 11, so that the side where the flow guiding structure 20 is located is the first end of the electrode dust removal device 60, that is, the electrode 70 passes through the flow guiding structure 20 first and then passes through the first air outlet 15 in sequence, thereby preventing the electrode dust removal device 60 from being installed backwards.

[0065] The central part of the flow guiding structure 20 is cylindrical, and the central part of the flow guiding structure is correspondingly set with the electrode. The central axis of the cylindrical structure extends along the third direction. According to the Coanda effect (when a fluid flows over a non-planar solid surface, the fluid tends to adhere to the surface, that is, the fluid will flow along the shape of the surface), the airflow blown out from the first outlet 90 flows along the surface of the cylindrical structure, thereby forming an airflow flowing in the fourth direction. This airflow can then gradually press down on the electrode from one end to the other along the fourth direction, avoiding the upward lifting effect caused by the vertical impact of the airflow, thereby eliminating the vibration and displacement of the electrode.

[0066] Figure 9The structure of the flow guide structure 20 in this embodiment is shown. Both ends of the flow guide structure 20 are spherical structures. Due to the viscosity of air, the electrode will also drive the surrounding air forward when it moves forward, which will generate lift force that makes the electrode rise. The spherical structure allows the airflow formed by the electrode moving along the outer wall of the spherical structure to flow along the third direction. This part of the airflow gradually presses down on the electrode from one end to the other end along the third direction. Furthermore, since the airflow formed by the electrode moving along the outer wall of the spherical structure extends the movement path of the airflow and increases the contact area between the airflow and the spherical surface, it increases the internal friction of the airflow and slows down the airflow speed. This can significantly reduce the lift force and ensure that the electrode will not shift or vibrate during the movement.

[0067] like Figure 10 As shown, in one embodiment of the present invention, the flow guiding structure 20 is a cylinder extending in a third direction.

[0068] like Figure 11 As shown, in one embodiment of the present invention, the flow guiding structure 20 includes a cylindrical segment 21 and two hemispherical structures 22. The cylindrical segment 21 extends along a third direction, and the two hemispherical structures 22 are disposed at opposite ends of the cylindrical segment 21.

[0069] like Figure 12 As shown, in one embodiment of the present invention, the flow guiding structure 20 has a cylindrical structure in the middle and tapered structures at both ends. One end extends out of the air blowing plate 112, and the tapered structure at this end is inclined toward the top surface of the air blowing plate 112, wherein the top surface of the air blowing plate 112 is the side facing the electrode.

[0070] like Figure 13 As shown, in one embodiment of the present invention, the flow guiding structure 20 has a cylindrical structure in the middle and tapered structures at both ends.

[0071] In one embodiment of the present invention, the first outlet 90 is disposed corresponding to the middle part of the flow guiding structure 20, and the middle part of the flow guiding structure 20 is located on the outlet side of the first outlet 90.

[0072] In this embodiment, the middle part of the flow guiding structure 20 corresponds to the air outlet side of the first outlet. The middle part of the flow guiding structure 20 is a cylindrical structure. When the high-speed airflow is ejected from the first outlet, it will flow along the cylindrical surface to form a downward airflow, effectively pressing the electrode sheet onto the conveyor belt.

[0073] See also Figures 1 to 8 As shown, in one embodiment of the present invention, the number of first outlet air ports 90 is at least two. The first outlet air ports 90 extend along a third direction. Along the fourth direction, at least one first outlet air port 90 is provided on each of the opposite sides of the flow guiding structure 20.

[0074] In this embodiment, at least one air outlet 90 is provided on each of the opposite sides of the flow guiding structure 20. The airflow on both sides helps to maintain the stability of the electrode on the conveyor belt and avoids the electrode from vibrating due to the impact of airflow on one side.

[0075] In one embodiment of the present invention, there are two first-outlet air ports 90, which are symmetrically arranged on opposite sides of the flow guiding structure 20 along the fourth direction.

[0076] With the above settings, the airflow can not only compress the electrode sheet, but also cancel out the potential lateral forces through the symmetrical airflow on both sides, ensuring that the electrode sheet moves in a straight line on the conveyor belt and will not deviate due to stronger winds on one side.

[0077] See also Figures 1 to 8 As shown and Figure 14 In one embodiment of the present invention, the third portion of a plurality of first air outlets 15 is arranged at intervals along a third direction to form a third branch 16. The third branch 16 is located between the first branch 17 and the second branch 80, and the flow guiding structure 20 is collinear with the third branch 16.

[0078] In this embodiment, by adding a third branch 16 between the first branch 17 and the second branch 80, the middle part of the electrode 70 can also be subjected to the pressure of the airflow from top to bottom, thereby enhancing the movement stability of the electrode 70 during the conveying process.

[0079] See also Figures 1 to 8 As shown and Figure 14 In one embodiment of the present invention, the first branch 17 and the second branch 80 are arranged symmetrically about the third branch 16.

[0080] The above configuration ensures that the airflow pressure on both sides of the electrode 70 is equal, preventing the electrode 70 from tilting or warping due to uneven airflow. This uniformity is crucial for maintaining the flatness of the electrode 70 during transport, improving the consistency and reliability of dust removal. Furthermore, the symmetrically distributed first air outlets 15 create a uniform pressure distribution on the electrode 70, helping to stabilize its position and reduce vibration during transport.

[0081] See also Figures 1 to 8 As shown and Figure 14 In one embodiment of the present invention, the first branch 17, the second branch 80 and the third branch 16 form an arrow-shaped structure.

[0082] With the above settings, an airflow that gradually diffuses from the center to both sides can be formed, ensuring that the airflow covers the entire surface of the electrode 70, which can not only improve dust removal efficiency, but also prevent the electrode 70 from shifting.

[0083] See also Figures 1 to 8 As shown, in one embodiment of the present invention, the first branch 17 includes a first branch 171 and a second branch 172 that are parallel to each other. The second branch 172 is located between the first branch 171 and the third branch 16. The plurality of first air outlets 15 forming the first branch 171 and the plurality of first air outlets 15 forming the second branch 172 are arranged alternately and staggered along a first direction.

[0084] In this embodiment, the staggered alternating arrangement of the first branch 171 and the second branch 172 ensures that the airflow is evenly distributed on the electrode 70. Furthermore, since the airflow does not act simultaneously and concentratedly on the same position of the electrode 70, but gradually diffuses, vibration of the electrode 70 due to airflow impact can be avoided.

[0085] See also Figures 1 to 8 As shown, in one embodiment of the present invention, the electrode dust removal device further includes a dust suction component 30, which is used to remove dust from the electrode 70. The base 11 is also provided with a plurality of first dust suction ports 18. Along the third direction, the plurality of first dust suction ports 18 and the plurality of first air outlets 15 forming the third branch 16 are alternately arranged, and the plurality of first dust suction ports 18 and the plurality of first air outlets 15 forming the third branch 16 all extend along the third direction. The dust suction component 30 can perform dust suction through the first dust suction ports 18.

[0086] In this embodiment, multiple first suction ports 18 and multiple first air outlets 15 forming the third branch 16 are arranged alternately, enabling the blowing and suction processes to work together more effectively. When the first air outlet 15 of the third branch 16 blows dust off the electrode 70, the adjacent first suction ports 18 can immediately suck in this dust, preventing secondary deposition of dust on the surface of the electrode 70 or diffusion into the surrounding environment, thus improving the immediate efficiency and cleanliness of dust removal. The suction assembly 30 can perform suction through the first suction ports 18 to clean the electrode.

[0087] See also Figures 1 to 8 As shown, in one embodiment of the present invention, the electrode dust removal device further includes a dust suction assembly 30, which is used to remove dust from the electrode 70. The base 11 is also provided with a plurality of second dust suction ports 19, which extend along a fourth direction and are perpendicular to the third direction. The plurality of second dust suction ports 19 are all located on the side of the flow guiding structure 20 facing the outward expansion structure. Along the fourth direction, the plurality of second dust suction ports 19 are symmetrically distributed on opposite sides of the third branch 16, and the dust suction assembly 30 can perform dust suction through the second dust suction ports 19.

[0088] In this embodiment, the second suction port 19 effectively captures dust that is blown up during the purging process but is not immediately absorbed by the first suction port 18, reducing the possibility of dust escaping into the surrounding environment. This ensures that the electrode 70 is thoroughly cleaned when passing through the electrode dust removal device 60. The suction assembly 30 can perform suction through the second suction port 19 to clean the electrode.

[0089] See also Figures 1 to 8 As shown, in one embodiment of the present invention, a gas flow channel is also provided on the base 11. The inlet end of the gas flow channel is configured to be connected to the gas supply device. A plurality of first outlets 15 are connected to the gas flow channel 13. The gas flow channel 13 includes a first flow channel 131 and a second flow channel 132. A plurality of first outlets 15 forming the second branch 80 are connected to the first flow channel 131. A plurality of first outlets 15 forming the first branch 17 are connected to the second flow channel 132.

[0090] In this embodiment, the independent arrangement of the first flow channel 131 and the second flow channel 132 allows the airflow of the first branch 17 and the second branch 80 to be controlled independently. The airflow pressure and flow rate of the first flow channel 131 and the second flow channel 132 can be adjusted according to the surface condition of different areas of the electrode 70, achieving personalized dust removal treatment for different parts of the electrode 70, thus improving the accuracy and flexibility of dust removal.

[0091] See also Figures 1 to 8 As shown, in one embodiment of the present invention, the first flow channel 131 includes a first main flow channel 1311 and a plurality of first branch flow channels 1312. The first main flow channel 1311 extends along a second direction, and the plurality of first branch flow channels 1312 are all connected to the first main flow channel 1311.

The plurality of second branch flow channels 1322 are connected to the plurality of first air outlets 15 forming the first branch 17 in a one-to-one correspondence.

[0092] Through the above configuration, precise airflow distribution can be achieved. The first main flow channel 1311 and the second main flow channel 1321 are responsible for guiding the main flow direction of the airflow, while the first branch flow channel 1312 and the second branch flow channel 1322 distribute the airflow to the corresponding first air outlet 15. The first branch flow channel 1312 corresponds one-to-one with the multiple first air outlets 15 forming the second branch 80, and the second branch flow channel 1322 corresponds one-to-one with the multiple first air outlets 15 forming the first branch 17, which can ensure that the airflow is evenly distributed on the surface of the electrode 70.

[0093] See also Figures 1 to 8 As shown, in one embodiment of the present invention, the cross-section of the first main channel 1311 gradually decreases along its extension direction, and the cross-section of the second main channel 1321 gradually decreases along its extension direction.

[0094] With the above settings, on the one hand, the blowing resistance can be increased to ensure the uniformity of the flow rate at the first air outlet 15; on the other hand, since the airflow speed naturally increases in the narrower flow channel, the energy consumption to maintain the required airflow speed can be reduced, thereby improving the energy efficiency ratio of the entire device.

[0095] See also Figures 1 to 8 As shown, in one embodiment of the present invention, the first flow channel 131 further includes a third branch flow channel 1313 connected to the first main flow channel 1311, and the outlet end of the third branch flow channel 1313 is connected to the first outlet 15 of the first part forming the third branch 16.

The air outlet end of the fourth branch flow channel 1323 is connected to the second air outlet 14 to realize the supply of air to the second air outlet 14.

[0098] In one embodiment, both the first air outlet 15 and the second air outlet 14 are tilted 30° relative to a third direction.

[0099] See also Figures 1 to 8 As shown, in one embodiment of the present invention, the electrode dust removal device further includes an air conveying section 12 mounted on the base 11. The air inlet end of the air conveying section 12 is configured to be connected to the air supply device.

The first flow channel 131 and the second flow channel 132 are both connected to the corresponding air storage chamber 123.

[0100] In this embodiment, the presence of the air storage chamber 123 can serve as a buffer for airflow. After being connected to the air supply device through the first connector 122, it can stably receive and store compressed air, which helps to maintain the stability of airflow when the air supply is unstable or the air pressure fluctuates, ensures the uniform output of airflow pressure, and improves the consistency of dust removal effect.

[0114] like Figure 15As shown, in one embodiment of the present invention, the base is further provided with a plurality of third air outlets 300. A portion of the plurality of third air outlets 300 are arranged at intervals along a first direction to form a fourth branch 301, and another portion are arranged at intervals along a second direction to form a fifth branch 302.

[0115] like Figure 16 As shown, in one embodiment of the present invention, the base is further provided with a plurality of fourth air outlets 400. A portion of the plurality of fourth air outlets 400 are arranged at intervals along a second direction to form a sixth branch 401, and another portion is arranged at intervals along a first direction to form a seventh branch 402.

[0116] As can be seen from the above description, the above embodiments of the present invention achieve the following technical effects: The device is equipped with a blowing assembly, a guiding structure, and a dust collection assembly. When the electrode sheet is conveyed to the electrode sheet dust removal device via a conveyor belt, it first passes through the guiding structure and the first outlet air port. Since the guiding structure is located on the outlet side of the first outlet air port, the gas blown out from the outlet side of the first outlet air port will pass through the guiding structure. The guiding structure can change the flow direction of the airflow blown out from the first outlet air port, so that the airflow blown from the first outlet air port from top to bottom becomes an airflow flowing along the fourth direction, and gradually blown from one end of the upper surface of the electrode sheet to the other end of the upper surface of the electrode sheet along the fourth direction. That is, the airflow whose flow direction is changed by the guiding structure, along the fourth direction, gradually presses down on the electrode sheet from one end to the other end of the electrode sheet. This gradual airflow avoids a large-area instantaneous impact on the electrode sheet and avoids the upward lifting effect caused by the vertical impact of the airflow, thereby eliminating the vibration and displacement of the electrode sheet. The electrode continues to move along the third direction. After exiting the area where the guide structure is located, the electrode then passes through multiple first air outlets in sequence. Because the first and second branches form an outward-expanding structure, the airflow diffusion range gradually increases along the third direction, creating an airflow that gradually expands outwards. This type of airflow, as the electrode moves along the third direction, gradually presses it down. Furthermore, this type of airflow only blows onto a portion of the electrode area, without immediately covering it, thus eliminating vibration and displacement. As can be seen from the above, the combination of the guide structure and the outward-expanding structure ensures that the electrode is firmly pressed onto the conveyor belt during transport, preventing vibration and displacement. Therefore, there is no need to increase the distance between the dust collection equipment and the electrode or reduce the blowing speed, thereby improving the dust collection effect of the dust collection equipment.
