[0053] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there can be a central component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time.

[0055] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this application and in the specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this application includes any and all combinations of one or more of the related listed items.

[0056] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0057] The assembly of the pole core usually includes three steps: lamination, cutting and cleaning. Lamination refers to stacking multiple pole pieces of the pole core together, and then connecting the pole pieces together by heating, pressing or ultrasonic welding to finally form a pole core. Due to errors in the stacking and pole piece processing process, the pole ears of the pole core after the lamination process may be uneven, and these unevenness may affect the subsequent cover welding and other processes. In order to ensure that the position and size of each pole ear are well consistent, so that the subsequent packaging and welding processes can proceed smoothly, it is necessary to accurately cut the uneven part of the front end of the pole ear. During the cutting process, the cut part of the waste will adhere to the pole ear. In order to prevent the waste from affecting the subsequent processing steps of the pole core, a dust removal device is usually used to clean the waste on the pole ear.

[0058] In the related technology, the dust removal device includes a shell, a dust removal brush and a driving assembly. The shell forms a dust removal chamber, and the dust removal brush is arranged in the dust removal chamber. One end of the dust removal brush is connected to the driving assembly through a coupling. The driving assembly is used to drive the dust removal brush to rotate to clean the pole ear extending into the dust removal chamber.

[0059] In the above structure, the dust brush as a whole presents a cantilever structure with one end fixed and the other end free. This also causes the free end of the dust brush to have a large displacement and deformation when the dust brush rotates, thereby increasing the radial force and friction between the dust brush and the coupling, reducing the transmission efficiency of the drive assembly for the dust brush, and increasing the possibility of coupling breakage.

[0060] Please refer to Figure 1 and Figure 2 In order to solve the above problems, the present application proposes a dust removal device 1000, which includes a shell 1, a dust removal brush 2 and a connecting component 3. The shell 1 is formed with a dust removal chamber 11, and the dust removal brush 2 is arranged in the dust removal chamber 11. The dust removal brush 2 has a first end 21 and a second end 22 that are relatively arranged. The first end 21 is used to connect with the driving component 8, and the dust removal brush 2 is used to clean the waste chips of the pole ear. One end of the connecting component 3 is connected to the second end 22, and the other end is rotatably connected to the cavity wall of the dust removal chamber 11.

[0061] The technical solution of the present application uses a connecting component 3 to connect the end of the dust removal brush 2 away from the driving assembly 8, so as to form a support at the end of the dust removal brush 2 away from the driving assembly 8, thereby stabilizing the rotation center of gravity of the dust removal brush 2, reducing the shaking amplitude of the dust removal brush 2 during rotation, reducing the radial force at the connection between the dust removal brush 2 and the driving assembly 8, and reducing the possibility of breaking at the connection between the dust removal brush 2 and the driving assembly 8. At the same time, the setting of the connecting component 3 can also improve the rotation coaxiality of the dust removal brush 2, reduce the possibility of the dust removal brush 2 contacting other structural parts, and then reduce the rotational friction of the dust removal brush 2, so that the power of the driving assembly 8 is more converted into the rotational force of the dust removal brush 2, increase the rotation speed of the dust removal brush 2, and improve the dust removal effect of the dust removal brush 2 on the pole ear.

[0062] Hereinafter, the dust removal device 1000 provided in the present application will be described in detail with reference to the accompanying drawings.

[0063] The dust removal device 1000 includes a shell 1, which serves as the supporting body of the dust removal device 1000 and is used to support and connect the various parts of the dust removal device 1000. The shape of the shell 1 can be rectangular, square, trapezoidal, or other regular or irregular shapes, and the present application does not limit this. The material of the shell 1 can be metal or plastic. When the material of the shell 1 is metal, the material of the shell 1 can be aluminum, iron, or steel. When the material of the shell 1 is plastic, the material of the shell 1 can be polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), and the present application does not limit this. In one embodiment of the present application, the shell 1 is made of transparent materials such as polypropylene (PP), polyethylene (PE), glass, etc., so that it is convenient for the operator to observe the cleaning condition of the pole core 2000.

[0064] The housing 1 includes a first plate 12, a second plate 13, a third plate 14, a fourth plate 15 and a fifth plate 16 connected to each other, and the second plate 13, the third plate 14, the fourth plate 15 and the fifth plate 16 are respectively arranged around the four edges of the first plate 12. The first plate 12, the second plate 13, the third plate 14, the fourth plate 15 and the fifth plate 16 are detachably connected by threads, so as to facilitate the installation of the dust removal brush 2 and the connecting component 3.

[0065] The dust removal device 1000 also includes a driving assembly 8, which is used to connect with the dust removal brush 2 to drive the dust removal brush 2 to rotate. The driving assembly 8 can be arranged outside the dust removal chamber 11, or partially extend into the dust removal chamber 11. Specifically, the driving assembly 8 includes a driving member 81, a coupling 82, and a mounting bracket 83. The driving member 81 serves as a power source for the driving assembly 8 and is used to provide power for the rotation of the dust removal brush 2. The driving member 81 can be a driving motor, an engine, or a rotary cylinder, and the present application does not impose any restrictions on this.

[0066] The coupling 82 is connected between the output shaft of the driving member 81 and the dust removal brush 2. The driving force of the driving member 81 can be transmitted to the dust removal brush 2 through the coupling 82, thereby driving the dust removal brush 2 to rotate. The coupling 82 can compensate for the installation error between the output shaft of the driving member 81 and the dust removal brush 2 through its own deformation, thereby ensuring the alignment and transmission efficiency between the output shaft and the dust removal brush 2.

[0067] The mounting frame 83 is connected to the first plate 12 of the housing 1, and the mounting frame 83 and the first plate 12 are arranged to form an installation space, and the coupling is accommodated in the installation space. The mounting frame 83 is provided with a first connecting hole 831, and the second plate 13 is provided with a second connecting hole 131. The driving member 81 is arranged on the side of the mounting frame 83 away from the installation space, and the output shaft of the driving member 81 extends into the installation space through the first connecting hole 831 and is connected to the coupling 82 arranged in the installation space. The dust removal brush 2 passes through the second connecting hole 131 and is connected to the coupling 82, so as to realize the mutual connection between the driving component 8 and the dust removal brush 2.

[0068] It can be understood that in other possible implementations of the present application, the coupling 82 can also be disposed in the dust removal chamber 11 and connected to the dust removal brush 2 also disposed in the dust removal chamber 11. The driving member 81 is fixed to the first plate body 12, and the output shaft of the driving member 81 can pass through the second connecting hole 131 of the second plate body 13 and extend into the dust removal chamber 11, and connect with the coupling 82 disposed in the dust removal chamber 11, thereby realizing the connection between the driving assembly 8 and the dust removal brush 2.

[0069] Please refer to Figures 1 to 3The dust removal device 1000 also includes a dust removal brush 2, which is arranged in the dust removal chamber 11 formed by the first plate 12, the second plate 13, the third plate 14, the fourth plate 15 and the fifth plate 16. The dust removal brush 2 includes a barrel 23 and bristles 24. The barrel 23 has a first end 21 and a second end 22 that are relatively arranged. The first end 21 of the barrel 23 is provided with a driving shaft, and the driving shaft passes through the second connecting hole 131 and is connected to the coupling 82. In one embodiment of the present application, the dust removal device 1000 also includes a driving bearing 9, which is arranged in the second connecting hole 131, and the driving shaft passes through the inner ring of the driving bearing 9 and is connected to the coupling 82. The driving bearing 9 is used to provide support for the rotational connection of the driving shaft in the second connecting hole 131, thereby ensuring the stability of the rotation of the dust removal brush 2.

[0070] The bristles 24 are arranged on the barrel 23, and the bristles 24 are used to contact the pole ear extending into the dust removal chamber 11 when the barrel 23 rotates, so as to clean the waste on the pole ear. The number of dust removal brushes 2 can be one or more, and this application does not limit this.

[0071] Please refer to Figure 2 and Figure 4 The dust removal device 1000 also includes a connecting component 3, one end of which is connected to the second end 22 of the barrel 23 of the dust removal brush 2, and the other end is rotatably connected to the wall of the dust removal chamber 11, so as to provide support for the end of the dust removal brush 2 away from the drive assembly 8, thereby stabilizing the rotation center of gravity of the dust removal brush 2, reducing the shaking amplitude of the dust removal brush 2 during rotation, improving the rotation coaxiality of the dust removal brush 2, reducing the radial force at the connection between the dust removal brush 2 and the drive assembly 8, and reducing the possibility of fracture at the connection between the dust removal brush 2 and the drive assembly 8. At the same time, the setting of the connecting component 3 can also reduce the possibility of contact between the barrel 23 and other structural parts, thereby reducing the rotational friction of the barrel 23, so that the power of the drive assembly 8 is more converted into the rotational force of the barrel 23, increasing the rotation speed of the barrel 23, and improving the dust removal effect of the dust removal brush 2 on the pole ear.

[0072] The connecting component 3 includes a connecting shaft 31, one end of the connecting shaft 31 is rotatably connected to the cavity wall of the dust removal chamber, and the other end is connected to the second end of the barrel 23 of the dust removal brush 2. The connecting shaft 31 and the barrel 23 can be formed as one piece, or can be formed separately and then connected to each other. In one embodiment of the present application, the connecting component 3 also includes a connecting piece 32, and the connecting shaft 31 is detachably connected to the second end 22 of the dust removal brush 2 through the connecting piece 32. In this way, when the connecting shaft 31 is damaged, it is only necessary to remove the connecting shaft 31 from the barrel 23 of the dust removal brush 2 and replace it, without replacing the entire dust removal brush 2, thereby reducing the maintenance cost of the dust removal device 1000 and improving the maintenance efficiency of the dust removal device 1000.

[0073] Please refer to Figures 2 to 5 The structure of the connecting member 32 can be various. The connecting member 32 can be a buckle and a slot respectively provided on the connecting shaft 31 and the dust removal brush. The buckle and the slot cooperate with each other to detachably connect the connecting shaft 31 to the barrel of the dust removal brush. The connecting member 32 can also be a first magnetic attraction portion and a second magnetic attraction portion respectively provided on the connecting shaft 31 and the dust removal brush. The first magnetic attraction portion and the second magnetic attraction portion can attract each other, so that the connecting shaft 31 can be detachably connected to the barrel of the dust removal brush.

[0074] In one embodiment of the present application, the connecting shaft 31 is provided with a first threaded hole 311 that penetrates along the axial direction of the connecting shaft 31, and correspondingly, the barrel 23 of the dust removal brush 2 is provided with a second threaded hole 231. The surface of the connecting member 32 is provided with an external thread, which can be a triangular thread, a trapezoidal thread, or a rectangular thread, which is limited by the present application. The connecting member 32 passes through the first threaded hole 311 and the second threaded hole 231 in sequence, so that the connecting shaft 31 and the barrel 23 can be detachably connected. Compared with other detachable connection methods, the setting cost of the connecting member 32 is low and the connection reliability is high. On the other hand, by adjusting the screwing length of the connecting member 32 in the second threaded hole 231, the distance between the dust removal brush 2 and the connecting shaft 31 can be adjusted, so that the connecting shaft 31 of the same length can be adapted to the dust removal brushes 2 of different lengths, thereby improving the versatility of the connecting shaft 31 and reducing the manufacturing cost of the dust removal device 1000.

[0075] In order to facilitate the installation and removal of the connecting member 32, the connecting shaft 31 and the dust removal brush 2, in one embodiment of the present application, the third plate 14 used to form the wall of the dust removal chamber 11 is provided with a mounting through hole 141, and the connecting shaft 31 is rotatably arranged in the mounting through hole 141. The connecting member 32 can extend out of the dust removal chamber 11 through the mounting through hole 141, and can be connected with the connecting shaft 31 and the dust removal brush 2 outside the dust removal chamber 11. In this way, the operable space of the connecting member 32 installation tool is increased, the installation difficulty of the connecting member 32, the connecting shaft 31 and the dust removal brush 2 is reduced, and the maintenance cost of the dust removal device 1000 is reduced.

[0076] The connecting shaft 31 includes a first shaft section 312 and a second shaft section 313 connected to each other, and the shaft diameter of the first shaft section 312 is larger than the shaft diameter of the second shaft section 313. In one installation method of the connecting shaft 31 and the cavity wall of the dust removal chamber 11, the dust removal device 1000 includes a connecting bearing 10, and the connecting bearing 10 is arranged in the installation through hole 141. The second shaft section 313 extends into the inner ring of the connecting bearing 10 to be connected with the connecting bearing 10. The first shaft section 312 contacts the side of the connecting bearing 10 facing the dust removal chamber 11, so as to provide axial limitation for the connecting bearing 10, reduce the possibility of the connecting bearing 10 coming out from the side of the installation through hole 141 facing the dust removal chamber 11 when the dust removal device 1000 is in operation, and improve the safety of the use of the dust removal device 1000.

[0077] In one embodiment of the present application, the second shaft segment 313 and the inner ring of the bearing ring are assembled by transition fit, and the operator can adjust the interference fit of the connecting shaft 31 and the connecting bearing 10 according to the actual processing conditions of the connecting shaft 31 and the connecting bearing 10, thereby reducing the difficulty of assembling the connecting shaft 31 and the connecting bearing 10 and improving the assembly efficiency of the connecting shaft 31 and the connecting bearing 10.

[0078] The connecting component 3 also includes a threaded fastener 33, which is sleeved on the connecting member 32, and the threaded fastener 33 contacts the connecting shaft 31 and the connecting bearing 10 on the side facing the dust removal chamber 11. The setting of the threaded fastener 33 can, on the one hand, lock the connecting member 32, reduce the possibility of the connecting member 32 coming off the connecting shaft 31 when the dust removal brush 2 rotates, and improve the safety performance of the dust removal device 1000. On the other hand, the threaded fastener 33 can provide axial limitation for the connecting bearing 10, reduce the possibility of the connecting bearing 10 coming off the mounting through hole 141 in the direction away from the side of the dust removal chamber 11, and further improve the safety performance of the dust removal device 1000.

[0079] Please refer to Figure 1 , Figure 2 and Figure 6 The dust removal device 1000 also includes a first air source component 4. Accordingly, the cavity wall of the dust removal chamber 11 is provided with a dust suction port 112. The first air source component 4 includes a first air pump and a dust collecting bin. The first air pump is connected to the dust suction port 112 at one end away from the dust removal chamber 11. The first air pump is used to form a negative pressure at the dust suction port 112. The waste scraps swept by the dust removal brush 2 in the dust removal chamber 11 can enter the first air source component 4 from the dust suction port 112 under the guidance of the negative pressure, and be collected by the dust collecting bin provided in the first air source component 4. In this way, while cleaning the dust removal chamber 11, it is also possible to prevent the waste scraps in the dust removal chamber 11 from randomly splashing, thereby improving the safety of the dust removal device 1000.

[0080] The dust removal device 1000 also includes a dust collection structure 5, which is formed with a dust collection chamber 51. The dust collection chamber 51 has a first dust collection port 52 and a second dust collection port 53 which are arranged opposite to each other. The first dust collection port 52 is connected to the dust suction port 112, and the second dust collection port 53 is connected to the first air source component 4. The cross-sectional area of ​​the dust collection chamber 51 gradually decreases from the first dust collection port 52 to the second dust collection port 53. In practical applications, the waste chips in the dust removal chamber 11 can enter the first air source component 4 from the dust suction port 112, the first dust collection port 52, and the second dust collection port 53. The structure in which the dust collection structure 5 gradually shrinks from the first dust collection port 52 to the second dust collection port 53 makes it difficult for the waste chips to escape from the dust collection structure 5 after entering the dust collection structure 5, thereby improving the dust collection effect of the first air source component 4.

[0081] The first air source component 4 and the dust collecting structure 5 can be provided with one or two, and the present application does not limit this. In one embodiment of the present application, the first plate 12 and the fourth plate 15 of the housing 1 are provided with a dust suction port 112. The first air source component 4 includes a first air source component 4a and a first air source component 4b, and the dust collecting structure 5 includes a dust collecting structure 5a and a dust collecting structure 5b. The dust collecting structure 5a is connected to the first plate 12 by bolts, and the first air source component 4a is connected to the dust collecting structure 5a. The dust collecting structure 5b is connected to the fourth plate 15 by bolts, and the first air source component 4b is connected to the dust collecting structure 5b. In this way, waste debris is adsorbed in two directions at the bottom and rear of the dust removal chamber 11 to prevent waste debris from splashing randomly in the dust removal chamber 11.

[0082] Please refer to Figure 1 , Figure 2 and Figure 7 The dust removal device 1000 further includes a second air source assembly (not shown in the figure) and an air guide structure 6, which is provided on the housing 1. One or two air guide structures 6 may be provided, and the present application does not limit this. For example, in one embodiment of the present application, two air guide structures 6 are provided, and two of them are connected to the fourth plate body 15 through the first air guide connecting plate, and the other two are connected to the fifth plate body 16 through the second air guide connecting plate.

[0083] The air guide structure 6 has a first air guide port 61 and a second air guide port 62, wherein the first air guide port 61 is connected to the second air source assembly, and the second air guide port 62 is arranged facing the dust removal chamber 11. The second air source assembly is used to pass airflow into the air guide structure 6. In a specific application, when the dust removal brush 2 rotates, the airflow of the second air source assembly can reach the dust removal brush 2 through the air guide structure 6, thereby assisting the dust removal brush 2 to clean the waste on the pole ear, thereby improving the cleaning efficiency of the dust removal device 1000.

[0084] It can be understood that in the above-mentioned air guide structure 6, the area of ​​the opening 111 of the first air guide port 61 determines the interface area between the air guide structure 6 and the second air source component. The area of ​​the opening 111 of the second air guide port 62 determines the airflow area of ​​the air guide structure 6 blowing toward the dust removal chamber 11. In one possible implementation of the present application, the area of ​​the opening 111 of the first air guide port 61 is smaller than the area of ​​the opening 111 of the second air guide port 62. A smaller first air guide port 61 can make the interface between the first air guide port 61 and the second air source component fit tightly, thereby improving the sealing of the interface between the air guide structure 6 and the second air source component, reducing the possibility of gas leakage, increasing the airflow intensity of the second air source component blowing toward the dust removal chamber 11, and improving the gas utilization rate of the second air source component. A larger second air guide port 62 can ensure the airflow area of ​​the air guide structure 6 blowing toward the dust removal chamber 11, and ensure the dust removal efficiency of the second air source component.

[0085] Please refer to Figure 6 and Figure 8 The dust removal chamber 11 is provided with an opening 111, through which the pole ear of the pole core 2000 can extend into the dust removal chamber 11. The dust removal device 1000 also includes two movable plates 7, which are movably arranged at the opening 111, and the two movable plates 7 can move towards or away from each other. In a specific application, when the pole ear of the pole core 2000 extends into the dust removal chamber 11, the dust removal device 1000 enters the dust removal state, and the two movable plates 7 move towards each other to clamp the pole core 2000 together, thereby realizing the positioning of the pole core 2000 in the dust removal chamber 11, and preventing the pole core 2000 from shaking during the dust removal process, which affects the dust removal effect. At the same time, during the process of the movable plate 7 and the pole core 2000 abutting against each other, the movable plate 7 and the pole core 2000 are jointly blocked at the opening 111, so as to prevent the waste on the pole ear from splashing out of the dust removal chamber 11 through the opening 111 when the dust removal brush 2 cleans the pole ear, thereby improving the safety of the dust removal device 1000. When the pole ear dust removal is completed, the dust removal device 1000 enters a stop state, at which time, the two movable plates 7 move away from each other, so that the movable plate 7 is separated from the pole core 2000, so that the pole core 2000 can exit the dust removal chamber 11 through the opening 111.

[0086] There are many ways to drive the movable plate 7 to move. The movable plate 7 can be driven manually or mechanically. In one embodiment of the present application, the dust removal device 1000 further includes a motor, a screw and a screw nut. The motor is disposed in the housing 1, the screw nut is sleeved on the screw, and the movable plate 7 is disposed on the screw nut. In a specific application, the motor can drive the screw to rotate by rotating itself, and drive the screw nut to move upward or downward through the rotation of the screw, and then drive the two movable plates 7 to move upward or downward through the screw nut, thereby realizing the movement of the two movable plates 7 closer to or away from each other.
