[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of some applications, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0043] The pole piece of a lithium battery is formed by coating a coating material on a foil. When the pole piece is cut by a cutting device, the coating material dust and foil scraps generated at the cutting place during the cutting process will adhere to the pole piece after the cutting is completed. Therefore, the dust and scraps on the cut pole piece need to be removed. To this end, the present application provides a dust removal component that can remove dust and scraps on the pole piece and occupies little space in the cutting device.

[0044] Of course, the dust removal assembly of the present application can not only remove dust from pole pieces, but also remove dust from other workpieces that require dust removal.

[0045] See also Figure 1 and Figure 3 As shown, the present application provides a dust removal assembly, including a dust extraction structure 100 and an air blowing structure 200. The air blowing structure 200 is used to blow air to a workpiece 4000 to blow away dust and other impurities adhering to the workpiece 4000 from the workpiece 4000, and the dust extraction structure 100 is used to extract dust and other impurities blown away from the workpiece 4000.

[0046] Specifically, the dust extraction structure 100 may include a dust extraction hood 110, and the dust extraction hood 110 may have a dust extraction port 120. Negative pressure gas is generated in the dust extraction port 120. The dust extraction port 120 can at least accommodate part of the workpiece 4000. Figure 4 shown.

[0047] That is to say, when the dust removal assembly 1000 removes dust from the workpiece 4000 , at least a portion of the workpiece 4000 can be accommodated in the dust extraction port 120 .

[0048] The air blowing structure 200 is disposed on the dust hood 110 and close to the dust extraction port 120 . The air outlet 210 of the air blowing structure 200 corresponds to the workpiece 4000 located in the dust extraction port 120 . The air blowing structure 200 is used to blow air toward the workpiece 4000 .

[0049] During dust removal, the blowing structure 200 can blow air to the workpiece 4000 located in the dust extraction port 120 to blow impurities such as dust adhering to the workpiece 4000 away from the workpiece 4000 , and the impurities blown away from the workpiece 4000 can be exactly sucked away by the dust extraction port 120 .

[0050] It can be seen that in the dust removal assembly 1000 of the present application, the dust extraction port 120 of the dust extraction hood 110 can accommodate at least part of the workpiece 4000, so that the workpiece 4000 to be dusted can be located in the dust extraction port 120, and the air blowing structure 200 is arranged on the dust extraction hood 110 and close to the dust extraction port 120, so that the air outlet 210 of the air blowing structure 200 can correspond to the workpiece 4000 located in the dust extraction port 120, and then the air blowing structure 200 can blow air to the workpiece 4000, and the impurities on the workpiece 4000 are blown away and just sucked away by the negative pressure gas generated in the dust extraction port 120. This method can not only realize the dust removal of the workpiece 4000, but also the dust extraction structure 100 and the air blowing structure 200 can be arranged together, so that the dust removal assembly 1000 is integrated, which is conducive to the dust removal assembly 1000 being arranged on the processing equipment and taking up less space of the equipment.

[0051] In some embodiments, the workpiece 4000 may be a pole piece, which is generally transported in the form of a coil. The pole piece may pass through the dust extraction port 120 during the transport process, so that dust removal of the pole piece can be achieved.

[0052] See also Figure 1 and Figure 3 In some embodiments, in order to facilitate the arrangement of the air blowing structure 200, the air blowing structure 200 may be arranged in the dust extraction port 120. The air blowing structure 200 may be an air knife.

[0053] Furthermore, the blowing structure 200 may be disposed at one end of the dust extraction port 120 , and the other end of the dust extraction port 120 is provided with an air avoidance groove 130 , and the air avoidance groove 130 is used to accommodate the workpiece 4000 .

[0054] For example, in the vertical direction, the dust extraction port 120 may include a first end 123 and a second end 124 that are arranged opposite to each other, the blowing structure 200 may be arranged at the first end 123 of the dust extraction port 120, and the second end 124 of the dust extraction port 120 may be provided with an air avoidance groove 130. The workpiece 4000 is located in the air avoidance groove 130, and the blowing structure 200 can blow air to the workpiece 4000 in the vertical direction, and impurities such as dust generated by the blowing are just sucked away by the negative pressure gas generated in the dust extraction port 120.

[0055] See also Figure 1 and Figure 3 The dust removal assembly 1000 may also include a partition plate 300 , which is disposed in the dust extraction port 120 , and the partition plate 300 divides the dust extraction port 120 into an independent first opening 121 and a second opening 122 , wherein the first opening 121 is used for exhausting air, and the blowing structure 200 is disposed at the second opening 122 .

[0056] It can be understood that since the blowing structure 200 is arranged in the dust extraction port 120, and the blowing structure 200 is used for blowing and the dust extraction port 120 is used for exhausting air, the partition plate 300 is arranged to separate the gas blown out by the blowing structure 200 from the gas drawn into the dust extraction port 120, so as to avoid turbulence affecting the quality of the blowing of the workpiece 4000 by the blowing structure 200 and avoiding affecting the quality of dust extraction of the dust extraction port 120.

[0057] In the above embodiment, the blowing structure 200 blows air toward the workpiece 4000 through the second opening 122 , and the dust extraction port 120 extracts air through the first opening 121 , which can well realize the flow of airflow and ensure the dust removal effect.

[0058] Specifically, one end of the partition plate 300 close to the blowing structure 200 can be connected to one end of the dust extraction port 120, and the end of the partition plate 300 away from the blowing structure 200 is connected to the other end of the dust extraction port 120 through a connecting piece, and there is a gap between the connecting piece and the side wall of the dust extraction port 120.

[0059] It can be understood that the gap between the connecting piece and the side wall of the dust extraction port 120 forms the first opening 121, that is, the air inlet. The connecting piece is used to support the partition plate 300 to prevent the partition plate 300 from shaking under the action of the gas.

[0060] Preferably, the partition plate 300 is arranged at an angle. The inclined partition plate 300 can make the chamber of the dust cover corresponding to the first opening 121 as large as possible, so that a sufficiently large negative pressure gas can be generated to improve the dust extraction effect.

[0061] Furthermore, in some embodiments, in order to ensure that impurities separated from the workpiece 4000 can be promptly extracted by the first opening 121 after the blowing structure 200 blows air to the workpiece 4000, the first opening 121 can correspond to the reflection direction of the gas when the blowing structure 200 blows toward the workpiece 4000.

[0062] For example, when the workpiece 4000 is a pole piece, the pole piece is transmitted through a transmission roller, and the pole piece forms an arc under the action of the transmission roller. At this time, if the blowing structure 200 blows air toward the arc surface of the pole piece in the vertical direction, the first opening 121 can correspond to the arc surface of the pole piece in the horizontal direction. In this way, the gas can just enter the first opening 121 after being reflected on the arc surface of the pole piece, and the impurities separated from the workpiece 4000 can just be extracted.

[0063] See also Figure 1 and Figure 3 In some embodiments, the first opening 121 is provided with an air avoidance groove 130. In this way, the workpiece 4000 can be accommodated at the first opening 121, which is conducive to the first opening 121 to extract dust separated from the workpiece 4000, and can further avoid the gas generated by the first opening 121 and the gas generated by the blowing structure 200 from affecting each other.

[0064] In some embodiments, when the corresponding part of the workstation for dust removal is arc-shaped, the air-avoiding groove 130 can be set to an arc-shaped structure. This method is conducive to extracting dust separated from the workpiece 4000 of the arc-shaped structure.

[0065] See also Figure 1 The dust removal component 1000 may further include a mounting structure 400, and the mounting structure 400 is disposed on the dust removal cover. The dust removal component 1000 may be disposed on an external processing device through the mounting structure 400, for example, may be disposed on a slitting device through the mounting structure 400.

[0066] In some embodiments, the mounting structure 400 may be provided at both ends of the dust cover, respectively.

[0067] The mounting structure 400 may include a first mounting member 410 and a second mounting member 420. The first mounting member 410 is disposed on the dust hood 110, and the dust hood 110 can be adjusted along the radial direction of the workpiece 4000 located in the air-avoiding groove 130 on the first mounting member 410; the second mounting member 420 is disposed on the first mounting member 410, and the second mounting member 420 can be adjusted along the axial direction of the workpiece 4000 located in the air-avoiding groove 130 on the first mounting member 410; the second mounting member 420 is used to be connected to the fixed structure, and the second mounting member 420 can be adjusted along the circumferential direction of the workpiece 4000 located in the air-avoiding groove 130 on the fixed structure.

[0068] For example, see Figure 5 A first adjustment hole 411 may be provided on the first mounting member 410 along the radial direction of the workpiece 4000 , a second adjustment hole 412 may be provided on the first mounting member 410 or the second mounting member 420 along the axial direction of the workpiece 4000 , and a third adjustment hole 421 may be provided on the second mounting member 420 along the circumferential direction of the workpiece 4000 .

[0069] The first mounting member 410 can be installed on the dust hood 110 after the first bolt passes through the first adjustment hole 411. The second mounting member 420 can be installed on the first mounting member 410 after the second bolt passes through the second adjustment hole 412. The second mounting member 420 can also be connected to an external processing device after the third bolt passes through the third adjustment hole 421. The position can be adjusted by moving the first bolt in the first adjustment hole 411, the second bolt in the second adjustment hole 412, and the third bolt in the third adjustment hole 421.

[0070] See also Figure 6 The present application also provides a cleaning mechanism, comprising a first conveying roller and the dust removal assembly 1000 in the above embodiment. The first conveying roller is used to contact with the first surface of the workpiece 4000, and the contact portion makes the workpiece 4000 in an arc state.

[0071] The portion of the first conveying roller 2000 that contacts the workpiece 4000 is located in the dust extraction port 120 , and the blowing structure 200 blows air toward the second surface of the workpiece 4000 in the arc state, wherein the second surface is another surface opposite to the first surface.

[0072] Furthermore, in some embodiments, the cleaning structure may further include a second conveying roller 3000, which is located on the transmission path of the workpiece 4000, and is used to contact the second surface of the workpiece 4000 and make the contact portion of the workpiece 4000 in an arc state.

[0073] There are two groups of dust removal components 1000, one group of dust removal components 1000 corresponds to the first conveying roller, and the other group of dust removal components 1000 corresponds to the second conveying roller, wherein the part of the second conveying roller that contacts the workpiece 4000 is located in the dust exhaust port 120, and the blowing structure 200 blows air toward the first surface of the workpiece 4000 in an arc state.

[0074] In the above structure, one group of dust removal components 1000 can be used to remove dust and clean the first surface of the workpiece 4000, and the other group of dust removal components 1000 can be used to remove dust and clean the second surface of the workpiece 4000, that is, both surfaces of the workpiece 4000 can be cleaned.

[0076] Specifically, the first surface of the workpiece 4000 transferred to the first conveyor roller 2000 may be dusted and cleaned by one of the dust removal assemblies 1000 , and the second surface of the workpiece 4000 transferred to the second conveyor roller 3000 may be dusted and cleaned by the other dust removal assembly 1000 .
