Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a dust removal device and a battery production line. Background Art

[0002] Energy conservation and emission reduction are the key to the sustainable development of the automobile industry. Electric vehicles have become an important part of the sustainable development of the automobile industry due to their advantages in energy conservation and environmental protection. For electric vehicles, battery technology is an important factor in their development.

[0003] During the manufacturing process of the battery, dust may adhere to the pole piece. If the pole piece with dust is used in battery production, it will affect the performance of the battery. Therefore, it is particularly important to effectively remove the dust adhered to the surface of the pole piece during the battery manufacturing process. Utility Model Content

[0004] The present application provides a dust removal device and a battery production line, which can improve the dust removal effect on the electrode.

[0005] This application is achieved through the following technical solutions:

[0006] In the first aspect, an embodiment of the present application provides a dust removal device, which includes a cleaning component, a dust suction component and an installation bin, wherein the cleaning component is used to clean the electrode piece; the dust suction component is arranged on one side of the cleaning component, and the dust suction component is used to perform negative pressure adsorption on dust generated during the cleaning process of the cleaning component; the installation bin cover is arranged on the cleaning component and the dust suction component, and the installation bin has a feed port and a discharge port for the electrode piece to pass through.

[0007] In the technical solution of the embodiment of the present application, the dust removal device can be used as a cleaning module and installed at any position in the conveying direction of the pole piece. After the pole piece enters from the feed port of the installation bin, it passes through the cleaning component. The cleaning component can remove the dust adsorbed on the surface of the pole piece from the surface. Compared with the open arrangement of the cleaning component and the dust collection component, the dust removed from the pole piece is confined to a specific space in the installation bin by installing the bin cover on the cleaning component and the dust collection component. On the one hand, the risk of dust leakage is reduced. On the other hand, the negative pressure area generated by the dust collection component in the relatively closed internal space of the installation bin is larger, which increases the area of ​​negative pressure adsorption of the dust collection component, and is more conducive to the negative pressure airflow generated by the dust collection component to promptly take away the dust floating in the installation bin, thereby improving the dust removal effect on the pole piece and reducing the probability of secondary adhesion of dust.

[0008] According to some embodiments of the present application, the cleaning assembly includes two cleaning components, and a gap is defined between the two cleaning components for the pole piece to pass through.

[0009] In the above scheme, a gap is formed for the electrode to pass through by two cleaning components that are spaced apart. The two cleaning components can respectively contact both sides of the electrode in the thickness direction, thereby achieving double-sided dust removal on the electrode, improving the dust removal effect of the electrode, and thereby reducing the failure rate of the battery.

[0010] According to some embodiments of the present application, the cleaning component includes a substrate and a cleaning brush, the substrate is installed in an installation bin; the cleaning brush is arranged on the substrate, and the cleaning brush is used to contact one side of the thickness direction of the pole piece; wherein, the number of the cleaning brushes is multiple, and the multiple cleaning brushes are distributed on the substrate at intervals along the width direction and / or length direction of the pole piece.

[0011] In the above scheme, a cleaning brush is installed on the substrate, and the cleaning brush contacts the surface of the pole piece, so that the dust adhering to the surface of the pole piece can be brushed off, and the dust adhering to the surface of the pole piece can be cleaned, and the structure is simple. In addition, multiple cleaning brushes are arranged on the substrate, and the multiple cleaning brushes cooperate with each other, so that the area in the length direction and / or width direction of the pole piece surface can be cleaned synchronously, with a wide coverage range and higher cleaning efficiency for the pole piece.

[0012] According to some embodiments of the present application, the cleaning component further includes a position adjustment component, and the position adjustment component is used to adjust the gap between the two cleaning components.

[0013] In the above scheme, through the setting of the position adjustment component, the position adjustment component can adjust the gap between the two cleaning components to adapt to the jitter during the electrode conveying process, or the cleaning requirements of electrode pieces of different thicknesses, and has a wider range of applications.

[0014] According to some embodiments of the present application, the position adjustment assembly includes an elastic member and a guide rod, the elastic member is extended along the thickness direction of the pole piece, the two ends of the elastic member are respectively connected to the substrate and the installation bin, the guide rod is arranged on the substrate along the thickness direction of the pole piece, and the guide rod is passed through the installation bin.

[0015] In the above scheme, through the setting of the elastic member, the two ends of the elastic member are respectively connected to the base plate and the installation bin. Under the expansion and contraction deformation of the elastic member, the cleaning brushes of the two cleaning components can always contact the two sides of the thickness direction of the pole piece, and the cleaning effect on the pole piece is good. In addition, in response to the floating influence during the transmission of the pole piece, or in response to the cleaning needs of pole pieces of different thicknesses, the elastic member can adaptively deform to adjust the gap between the two cleaning components, without the need for human intervention, and the adjustment is simple and has a wide range of applications. The guide rod is inserted into the installation bin, and the guide rod can guide the up and down adjustment direction of the cleaning component, guiding the cleaning component to float up and down relative to the installation bin, so that the stability of the up and down movement of the cleaning component is higher.

[0016] According to some embodiments of the present application, the end of the guide rod located outside the installation chamber has a limiting portion, and the limiting portion is used to make the end of the guide rod facing away from the substrate be located outside the installation chamber.

[0017] In the above solution, the limiting part is provided so that the end of the guide rod away from the base plate will not enter the installation chamber, thereby improving the installation stability of the cleaning component.

[0018] According to some embodiments of the present application, the dust suction component includes a dust suction part, an air suction part and a collecting bin. The dust suction part is arranged on the substrate and is located on both sides of the width direction of the pole piece. The dust suction part has a dust suction port facing the cleaning part. The air suction part is connected with the dust suction port through an air suction pipe, and the air suction part is used to form a negative pressure in the area of ​​the dust suction port. The collecting bin is connected with the air suction part, and a dust filter net is arranged at the exhaust port of the collecting bin. The dust filter net is used to prevent the dust adsorbed by the dust suction part from being discharged from the exhaust port.

[0019] In the above scheme, after the cleaning component brushes off the dust adhered to the surface of the pole piece, the dust floats in the vicinity of the pole piece, and the dust suction component is located on both sides of the width direction of the pole piece. The exhaust component can generate negative pressure airflow in the vicinity of the pole piece. The negative pressure airflow absorbs the dust brushed off by the pole piece into the collection bin. Under the blocking effect of the dust filter net, the dust is isolated in the collection bin, and the airflow is discharged from the dust filter net.

[0020] According to some embodiments of the present application, the dust suction component has a bottom wall and a side wall close to the cleaning component, and the number of dust suction ports is multiple, and the multiple dust suction ports are located on the bottom wall and the side wall.

[0021] In the above scheme, multiple dust suction ports are located on the side wall and bottom wall of the dust suction component, which can not only timely absorb the dust brushed out by the dust suction component close to the cleaning brush position, but also absorb the dust floating between the two cleaning components below the dust suction component, thereby improving the dust suction range of the dust suction component.

[0022] According to some embodiments of the present application, the collecting bin is located outside the installing bin.

[0023] In the above solution, the collecting bin is located outside the installation bin, which is convenient for cleaning the dust collected in the collecting bin and is more convenient to handle compared to when the collecting bin is located inside the installation bin.

[0024] According to some embodiments of the present application, the number of cleaning components is set to multiple groups, and the multiple groups of cleaning components are distributed in the installation bin at intervals along the feeding direction of the electrode piece.

[0025] In the above scheme, by setting the number of cleaning components to multiple groups, the multiple groups of cleaning components are spaced apart along the feeding direction of the pole piece, thereby achieving multiple cleaning and dust removal of the pole piece one by one, and the dust removal effect of the pole piece is better.

[0026] According to some embodiments of the present application, the dust removal device also includes a material guide roller assembly, which is arranged in the installation bin and located between two adjacent cleaning assemblies, and the material guide roller assembly is used to guide the pole piece through the cleaning assembly.

[0027] In the above scheme, by arranging the guide roller assembly between the multiple groups of cleaning components, the guide roller assembly can support and guide the pole piece, which is conducive to the pole piece being able to pass through the multiple groups of cleaning components more smoothly.

[0028] According to some embodiments of the present application, the guide roller assembly includes two guide rollers, and the two guide rollers are rotatably mounted on corresponding substrates of the two cleaning components.

[0029] In the above scheme, the gap between the two oppositely arranged guide rollers can allow the pole piece to pass through. When the two guide rollers can passively rotate along their axial directions, the two guide rollers respectively contact the two sides of the thickness direction of the pole piece, providing bearing effect on the pole piece while guiding the pole piece through the cleaning assembly, thereby reducing the resistance of the pole piece through the cleaning assembly and being more conducive to the pole piece completing the dust removal operation.

[0030] According to some embodiments of the present application, the dust removal device also includes a transmission roller assembly, which is arranged at the feed port and / or the discharge port of the installation bin, and the transmission roller assembly is used to guide the pole piece in and out of the installation bin.

[0031] In the above scheme, a transmission roller assembly is provided at the feed port and / or the discharge port of the installation bin, and the transmission roller assembly plays the function of transferring materials, which is beneficial for the cleaning and dust removal of the dust on the surface of the pole piece through the installation bin.

[0032] In a second aspect, an embodiment of the present application further provides a battery production line, which includes the dust removal device in any of the above embodiments.

[0033] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become apparent from the description below, or will be learned through the practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] In some embodiments of the present application, the battery may be a battery module. When there are multiple battery cells, the multiple battery cells are arranged and fixed to form a battery module.

[0049] In some embodiments of the present application, the battery may be a battery pack, which includes a case and battery cells, wherein the battery cells or battery modules are accommodated in the case.

[0055] At present, during the manufacturing process of batteries, after the electrode pieces are cut, dust or burrs are easily attached to the surface of the electrode pieces. If the electrode pieces with dust are used in battery production, the performance of the battery will be affected. Therefore, the surface of the electrode pieces after cutting usually needs to be dusted, but the dust removal effect of the electrode pieces is poor in the prior art.

[0056] Based on the above considerations, in order to improve the dust removal effect on the electrode piece, the present application designs a dust removal device, which includes a cleaning component, a dust suction component and an installation bin, wherein the cleaning component is used to clean the electrode piece; the dust suction component is arranged on one side of the cleaning component, and the dust suction component is used to perform negative pressure adsorption on the dust generated during the cleaning process of the cleaning component; the installation bin cover is arranged on the cleaning component and the dust suction component, and the installation bin has a feed inlet and a discharge port for the electrode piece to pass through.

[0057] In such a dust removal device, by installing the bin cover on the cleaning component and the dust collection component, the dust removed from the pole piece is confined to a specific space in the installation bin, reducing the risk of dust leakage. In addition, the negative pressure area generated by the dust collection component in the relatively closed internal space in the installation bin is larger, increasing the area of ​​negative pressure adsorption of the dust collection component, and making it more conducive for the negative pressure airflow generated by the dust collection component to promptly remove the dust floating in the installation bin, thereby improving the dust removal effect on the pole piece.

[0058] The present application provides a dust removal device, please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 A schematic diagram of the structure of a dust removal device in some embodiments of the present application; Figure 2 A schematic structural diagram of a dust removal device according to some embodiments of the present application from another angle; Figure 3 for Figure 1 The dust removal device 100 is a schematic diagram of the structure after the installation bin and the conveying roller are removed. The dust removal device 100 includes a cleaning component 20, a dust suction component 30 and an installation bin 10. The cleaning component 20 is used to clean the electrode piece. The dust suction component 30 is arranged on one side of the cleaning component 20. The dust suction component 30 is used to negatively absorb the dust generated during the cleaning process of the cleaning component 20. The installation bin 10 is covered by the cleaning component 20 and the dust suction component 30. The installation bin 10 has a feed port 11 and a discharge port 12 for the electrode piece to pass through.

[0059] The installation bin 10 is a cover structure, and has an installation cavity inside. The installation bin 10 provides a cover and installation base for the cleaning assembly 20 and the dust collection assembly 30. Two support seats 13 may be provided at the bottom of the installation bin 10, and the two support seats 13 provide a bearing function for the installation bin 10.

[0060] The cleaning component 20 is a component that can separate the dust adhering to the surface of the electrode from the electrode. The cleaning component 20 can be of various structures. For example, the cleaning component 20 can be blown or brushed. The cleaning component 20 can remove dust from one side of the electrode or from both sides of the electrode, which can be determined according to actual conditions.

[0061] The dust collection component 30 refers to a component that can absorb and collect dust that has been separated from the surface of the electrode. For example, the dust collection component 30 can be a vacuum cleaner.

[0062] The feed port 11 is an opening for the electrode to be dedusted to enter the installation bin 10, and the discharge port 12 is an opening for the electrode to be dedusted to pass through the installation bin 10. The feed port 11 and the discharge port 12 are located on opposite sides of the installation bin 10 along the conveying direction of the electrode. Figure 1 or Figure 2 In order to better illustrate the internal situation of the installation bin 10, the installation bin 10 is completely open on one side of the opening of the feed port 11 and the discharge port 12. In fact, a baffle (not shown in the figure) can be provided on one side of the feed port 11 and the discharge port 12 of the installation bin 10, and the baffle only needs to expose the opening space required for the electrode to pass through the feed port and the discharge port, so that the sealing effect of the interior of the installation bin 10 can be better ensured.

[0063] It should be noted that although the setting of the feed port 11 and the discharge port 12 on the installation bin 10 makes the installation bin 10 have an opening, the installation bin 10 is covered by the cleaning component 20 and the dust collection component 30, and can still provide a relatively closed space for the cleaning component 20 and the dust collection component 30. The dust generated by the cleaning component 20 during the cleaning process is not easy to leak out. When the dust collection component 30 generates negative pressure to absorb the dust, compared with the dust collection component 30 with a completely open setting, the negative pressure area generated by the dust collection component 30 under the same working power is relatively larger, and it is also more conducive to the dust collection component 30 to absorb and collect the dust detached from the surface of the electrode.

[0064] In the technical solution of the embodiment of the present application, the dust removal device can be used as a cleaning module and installed at any position in the conveying direction of the pole piece. After the pole piece enters from the feed port 11 of the installation bin 10, it passes through the cleaning component 20. The cleaning component 20 can remove the dust adsorbed on the surface of the pole piece from the surface. Compared with the open arrangement of the cleaning component 20 and the dust collection component 30, the installation bin 10 is covered with the cleaning component 20 and the dust collection component 30, and the dust removed from the pole piece is confined to a specific space in the installation bin 10. On the one hand, the risk of dust leakage is reduced. On the other hand, the negative pressure area generated by the dust collection component 30 in the internal space of the relatively closed installation bin 10 is larger, which increases the area of ​​negative pressure adsorption of the dust collection component 30, and is more conducive to the negative pressure airflow generated by the dust collection component 30 to promptly take away the dust floating in the installation bin 10, reducing the probability of secondary adhesion, thereby improving the dust removal effect on the pole piece.

[0065] According to some embodiments of this application, please refer to Figure 3 and Figure 4 , Figure 3 for Figure 1 A schematic diagram of the structure of the dust removal device after removing the installation bin and the material transfer roller; Figure 4 for Figure 3 The cleaning assembly 20 includes two cleaning components 21, and a gap is defined between the two cleaning components 21 for the pole piece to pass through.

[0066] The gap refers to the space area between the two cleaning components 21 after the pole piece enters from the feed port 11 of the installation bin 10 .

[0067] A gap is formed by distributing two cleaning components 21 at intervals for the electrode to pass through. The two cleaning components 21 can respectively contact the two sides of the electrode in the thickness direction Z, thereby achieving double-sided dust removal on the electrode, improving the dust removal effect of the electrode, and further reducing the failure rate of the battery.

[0068] According to some embodiments of this application, please continue to refer to Figure 4The cleaning component 21 includes a substrate 210 and a cleaning brush 211, and the substrate 210 is installed in the installation bin 10; the cleaning brush 211 is arranged on the substrate 210, and the cleaning brush 211 is used to contact one side of the thickness direction Z of the electrode; wherein, the number of the cleaning brushes 211 is multiple, and the multiple cleaning brushes 211 are spaced apart on the substrate 210 along the width direction Y and / or the length direction X of the electrode.

[0069] The substrate 210 refers to a plate structure for installing the cleaning brush 211 , and the substrate 210 provides installation and bearing functions for the cleaning brush 211 .

[0070] The thickness direction Z of the electrode piece refers to the extension direction of the thickness direction of the electrode piece in the installation bin 10. The length direction X of the electrode piece refers to the distribution direction of the feed port 11 and the discharge port 12 of the installation bin 10, that is, the conveying direction of the electrode piece in the installation bin 10. The width direction Y of the electrode piece refers to the direction perpendicular to the length direction of the electrode piece; wherein the width direction Y, the length direction X and the thickness direction Z of the electrode piece are perpendicular to each other.

[0071] The cleaning brush 211 may be a brush structure made of various materials, but in order to reduce the damage of the cleaning brush 211 to the electrode, the cleaning brush 211 may be a brush structure made of flexible material. For example, the cleaning brush 211 may be a flexible brush such as a plush brush or a sponge brush.

[0072] A plurality of cleaning brushes 211 are distributed on the substrate 210 at intervals along the width direction Y and / or the length direction X of the pole piece. It can be understood that the plurality of cleaning brushes 211 can be distributed at intervals along the width direction of the pole piece, can be distributed at intervals along the length direction of the pole piece, or can be distributed along both the length direction of the pole piece and the width direction of the pole piece on the substrate 210. In this embodiment, the plurality of cleaning brushes 211 are distributed at intervals along the length direction X and the width direction Y of the pole piece on the substrate 210.

[0073] The cleaning brush 211 is installed on the substrate 210, and the cleaning brush 211 contacts the surface of the pole piece, so that the dust adhering to the surface of the pole piece can be brushed off, and the dust adhering to the surface of the pole piece can be cleaned, and the structure is simple. In addition, the multiple cleaning brushes 211 are arranged on the substrate 210, and the multiple cleaning brushes 211 cooperate with each other, so that the area in the length direction and / or width direction of the pole piece surface can be cleaned synchronously, with a wide coverage range and higher cleaning efficiency for the pole piece.

[0074] According to some embodiments of this application, please continue to refer to Figure 3 and Figure 4 The cleaning component 21 further includes a position adjustment component 22 , and the position adjustment component 22 is used to adjust the gap between the two cleaning components 21 .

[0075] The position adjustment component 22 refers to a structure that can adjust the position of the cleaning component 21. The position adjustment component 22 can be a variety of adjustment mechanisms. For example, the position adjustment component 22 can be a linear drive 53, which is installed in the installation bin 10. The output end of the linear drive 53 is connected to the substrate 210 of the cleaning component 21. The position adjustment of the cleaning component 21 is achieved through the telescopic effect of the linear drive 53, thereby adjusting the distance between the two cleaning components 21. For example, the linear drive 53 can be a linear drive mechanism such as a cylinder, a hydraulic cylinder, or a screw nut sub-mechanism. Of course, the position adjustment component 22 can also be an elastic member 220, which can be provided between the substrate 210 and the installation bin 10 with a guide rod 221. The telescopic deformation of the elastic member 220 can achieve the position adjustment of the cleaning component 21. The guide rod 221 plays a guiding role, guiding the telescopic direction of the cleaning component 21, thereby adjusting the distance between the two cleaning components 21.

[0076] By setting the position adjustment component 22, the position adjustment component 22 can adjust the gap between the two cleaning components 21 to adapt to the shaking during the electrode conveying process, or the cleaning requirements of electrode pieces of different thicknesses, and has a wider range of applications.

[0077] According to some embodiments of the present application, the position adjustment assembly 22 includes an elastic member 220 and a guide rod 221. The elastic member 220 is extended along the thickness direction Z of the pole piece. The two ends of the elastic member 220 are respectively connected to the substrate 210 and the installation bin 10. The guide rod 221 is arranged on the substrate 210 along the thickness direction Z of the pole piece. The guide rod 221 passes through the installation bin 10.

[0078] The elastic member 220 may be a variety of spring structures, for example, the elastic member 220 may be a compression spring, a spring or a rubber column, etc. In this embodiment, the elastic member 220 is a compression spring.

[0079] The guide rod 221 is a rod structure, and the guide rod 221 refers to a rod that can guide the elastic member 220 to deform, that is, guide the direction of the lifting and deformation of the substrate 210. The installation chamber 10 is provided with a guide hole for the guide rod 221 to pass through, and the guide rod 221 is matched with the guide hole on the installation chamber 10.

[0080] The guide rod 221 and the elastic member 220 may be integrally arranged or separately arranged. That is, the guide rod 221 may be inserted into the elastic member 220, or the guide rod 221 and the elastic member 220 may be separately arranged. In this embodiment, the guide rod 221 is inserted into the elastic member 220.

[0081] The number of the position adjustment components 22 can be set to multiple groups, and the multiple groups of position adjustment components 22 are distributed on the substrate 210 at intervals.

[0082] Through the setting of the elastic member 220, the two ends of the elastic member 220 are respectively connected to the substrate 210 and the installation bin 10. Under the expansion and contraction deformation of the elastic member 220, the cleaning brushes 211 of the two cleaning components 21 can always contact the two sides of the thickness direction Z of the pole piece, and the cleaning effect on the pole piece is good. In addition, in response to the floating influence during the transmission of the pole piece, or in response to the cleaning needs of pole pieces of different thicknesses, the elastic member 220 can adaptively deform to adjust the gap between the two cleaning components 21, without human intervention, and the adjustment is simple and has a wide range of applications. The guide rod 221 is inserted into the installation bin 10, and the guide rod 221 can guide the up and down adjustment direction of the cleaning component 21, guide the cleaning component 21 to float up and down relative to the installation bin 10, so that the stability of the up and down movement of the cleaning component 21 is higher.

[0083] Specifically, when dealing with a pole piece with a larger thickness dimension, the elastic member 220 is compressed on one side of the thickness direction Z of the pole piece, so that the elastic member 220 undergoes adaptive compression deformation, and the compression deformation of the elastic member 220 increases, thereby allowing the two cleaning components 21 to move to the side away from the pole piece. During this process, the cleaning brush 211 is always in contact with the surface of the pole piece, so that the dust on the surface of the pole piece is brushed away. Similarly, when dealing with a pole piece with a smaller thickness dimension, the elastic potential energy accumulated by the elastic member 220 becomes smaller, and the two cleaning components 21 automatically approach the pole piece. During this process, the cleaning brush 211 is always in contact with the surface of the pole piece, so that the dust on the surface of the pole piece is brushed away. Of course, during the transportation process of the pole piece, the pole piece may shake or float up and down, and the elastic member 220 can automatically filter the fluctuation of the pole piece.

[0084] In addition, in order to further improve the stability of the substrate 210 floating up and down relative to the installation chamber 10, the substrate 210 includes a first base 2101 and a second base 2102, the first base 2101 and the second base 2102 are connected, the cleaning brush 211 is installed on the first base 2101, and the second base 2102 can extend outside the installation chamber 10, that is, the installation chamber 10 is provided with a clearance hole at a position corresponding to the second base 2102, and the second base 2102 is penetrated and matched with the clearance hole. A blocking portion 2103 is provided at one end of the second base 2102 located outside the installation chamber 10. The blocking portion 2103 prevents the second base 2102 from completely entering the installation chamber 10. In this way, the second base 2102 and the guide rod 221 can be guided together to guide the cleaning component 21 to rise and fall, and the stability of the floating process of the cleaning component 21 is higher.

[0085] According to some embodiments of this application, please refer to Figure 3 The end of the guide rod 221 located outside the installation chamber 10 has a limiting portion 222 , and the limiting portion 222 is used to make the end of the guide rod 221 away from the substrate 210 located outside the installation chamber 10 .

[0086] The limiting portion 222 may be a variety of limiting structures. For example, the limiting portion 222 may be an enlarged end, that is, an enlarged structure is formed at the end of the guide rod 221 protruding radially, and the size of the enlarged structure is larger than the size of the guide hole.

[0087] The limiting portion 222 can prevent the end of the guide rod 221 away from the substrate 210 from entering the installation chamber 10 , thereby improving the installation stability of the cleaning component 21 .

[0088] According to some embodiments of this application, please combine Figure 3 and Figure 4 The dust suction component 30 includes a dust suction component 31, an exhaust component and a collecting bin 32. The dust suction component 31 is arranged on the substrate 210 and is located on both sides of the width direction Y of the electrode. The dust suction component 31 has a dust suction port 312 facing the cleaning component 21; the exhaust component is used to form a negative pressure in the area of ​​the dust suction port 312; the collecting bin 32 is connected to the air outlet of the exhaust component, and a dust filter net (not shown in the figure) is arranged at the exhaust port of the collecting bin 32. The dust filter net is used to prevent the dust adsorbed by the dust suction component 31 from being discharged from the exhaust port.

[0089] The dust suction components 31 are arranged on both sides of the pole piece in the width direction, that is, both sides of the pole piece in the width direction are provided with dust suction components 31 .

[0090] In the case where there are two cleaning components 21 in the cleaning assembly 20, the dust suction component 31 may include two sub-dust suction components 31, which correspond to the two sides of the thickness direction of the pole piece, and are respectively installed on the corresponding substrates 210 of the two cleaning components 21. The two sub-dust suction components 31 may be connected through a connecting pipe 33, and then share the same exhaust component.

[0091] The air extraction component is a component that can generate negative pressure airflow, for example, the air extraction component can be an air pump or an air extractor. The air extraction body can be arranged inside the dust suction component 31, or can be arranged in the collection bin 32 or between the collection bin 32 and the dust suction component 31.

[0092] The collecting bin 32 is a box structure, and the internal cavity of the collecting bin 32 can provide a temporary storage function for the collected dust.

[0093] A dust filter is a mesh structure used to remove solid dust from gas. For example, the dust filter can be a coarse filter.

[0094] After the cleaning component 21 brushes off the dust adhered to the surface of the pole piece, the dust floats in the vicinity of the pole piece, and the dust suction component 31 is located on both sides of the width direction of the pole piece. The exhaust component can generate negative pressure airflow in the vicinity of the pole piece. The negative pressure airflow absorbs the dust brushed off the pole piece into the collection bin 32. Under the blocking effect of the dust filter net, the dust is isolated in the collection bin 32, and the airflow is discharged from the dust filter net.

[0095] According to some embodiments of this application, please refer to Figure 5 , Figure 5 for Figure 3 The dust collecting component 31 has a bottom wall 310 and a side wall 311 close to the cleaning component 21 , and a plurality of dust collecting ports 312 are located on the bottom wall 310 and the side wall 311 .

[0096] The dust suction component 31 can be a box structure with a cavity inside. The dust suction port 312 is distributed on the bottom wall 310 and the side wall 311 of the dust suction component 31. The dust suction port 312 is connected to the cavity, and the exhaust pipe is connected to the cavity. The dust and airflow absorbed by the dust suction port 312 pass through the cavity and enter the exhaust pipe, and finally enter the collection bin 32.

[0097] The bottom wall 310 is the wall surface of the bottom of the dust collecting component 31 , and the side wall 311 is the side wall surface of the box body. The bottom wall 310 and the side wall 311 are arranged perpendicular to each other.

[0098] By having multiple dust suction ports 312 located on the side wall 311 and the bottom wall 310 of the dust suction component 31, it is possible to timely absorb the dust brushed out by the dust suction component 31 close to the cleaning brush 211, and to absorb the dust floating between the two cleaning components 21 below the dust suction component 31, thereby increasing the dust suction range of the dust suction component 30.

[0099] According to some embodiments of the present application, the collection bin 32 is located outside the installation bin 10 .

[0100] The collecting bin 32 is a bin structure, and has a cavity for storing dust inside. The exhaust pipe is connected to one side of the collecting bin 32. The dust filter can be set on the top surface of the collecting bin 32, or on the side wall 311 of the collecting bin 32 opposite to the exhaust pipe to facilitate the circulation of air.

[0101] In addition, the collection bin 32 and the installation bin 10 may be fixedly connected or detachably connected. The collection bin 32 and the installation bin 10 may be fixedly connected. In order to better discharge the dust collected in the collection bin 32, a drawer may be provided on the side wall 311 in the collection bin 32. The drawer is used to store dust. The dust can be discharged by opening the drawer regularly.

[0102] Of course, the collection bin 32 and the installation bin 10 can also be connected by a card, which is convenient for the assembly and disassembly of the collection bin 32. The top surface of the collection bin 32 can be covered with a cover. When the dust in the collection bin 32 needs to be cleaned, the collection bin 32 is removed, the cover is opened, and the dust in the collection bin 32 is discharged in a centralized manner.

[0103] The collecting bin 32 is located outside the installation bin 10 , which is convenient for cleaning the dust collected in the collecting bin 32 and for handling compared to when the collecting bin 32 is located inside the installation bin 10 .

[0104] According to some embodiments of the present application, the number of cleaning assemblies 20 is set to multiple groups, and the multiple groups of cleaning assemblies 20 are distributed in the installation bin 10 at intervals along the feeding direction of the electrode piece.

[0105] In this embodiment, please refer to Figure 4 The number of cleaning components 20 is set to two groups, and the two groups of cleaning components 21 are spaced apart and distributed along the feeding direction of the electrode piece.

[0106] When there are two groups of cleaning components 20, the dust suction component 31 in the dust suction component 30 can cover the two groups of cleaning components 20 along the conveying direction of the electrode, that is, the same dust suction component 31 can absorb the dust generated on the same side of the two groups of cleaning components 20, thereby reducing the number of dust suction components 31 and making the structure simpler.

[0107] By setting the number of cleaning components 20 to multiple groups, the multiple groups of cleaning components 20 are spaced apart along the feeding direction of the pole piece, thereby achieving multiple cleaning and dust removal of the pole piece one by one, and the dust removal effect of the pole piece is better.

[0108] According to some embodiments of this application, please refer to Figure 4 The dust removal device also includes a guide roller assembly 40, which is disposed in the installation bin 10 and between two adjacent cleaning assemblies 20. The guide roller assembly 40 is used to guide the pole piece through the cleaning assembly 20.

[0109] The guide roller assembly 40 refers to a guide structure for guiding the pole piece to pass through the cleaning assembly 20. The number of guide rollers 41 in the guide roller assembly 40 may be one or two. When the number of guide rollers 41 is one, the guide roller 41 contacts the lower surface of the pole piece, provides a bearing function to the lower surface of the pole piece, and guides the pole piece to pass through the cleaning assembly 20. Of course, when the number of guide rollers 41 is two, the two guide rollers 41 are relatively spaced and distributed, and the two guide rollers 41 may contact the two sides of the thickness direction of the pole piece respectively, which has a better guiding effect on the pole piece.

[0110] By arranging the guide roller assembly 40 between the multiple groups of cleaning assemblies 20 , the guide roller assembly 40 can support and guide the pole piece, so that the pole piece can pass through the multiple groups of cleaning assemblies 20 more smoothly.

[0111] According to some embodiments of the present application, the guide roller assembly 40 includes two guide rollers 41 , and the two guide rollers 41 are rotatably mounted on corresponding substrates 210 of two cleaning components 21 .

[0112] Both ends of the guide roller 41 in the length direction can be rotatably mounted on the substrate 210 via bearings. During the transportation of the pole piece, the pole piece contacts the guide roller 41, thereby causing the guide roller 41 to rotate. The rotation of the guide roller 41 guides the pole piece to move along the transportation direction.

[0113] The gap between the two oppositely arranged guide rollers 41 can allow the pole piece to pass through. When the two guide rollers 41 can passively rotate along their axial directions, the two guide rollers 41 respectively contact the two sides of the thickness direction of the pole piece, providing a bearing effect on the pole piece while guiding the pole piece through the cleaning assembly 20, thereby reducing the resistance of the pole piece through the cleaning assembly 20 and being more conducive to the pole piece completing the dust removal operation.

[0114] According to some embodiments of the present application, the dust removal device also includes a transmission roller assembly 50, which is arranged at the feed port 11 and / or the discharge port 12 of the installation bin 10, and the transmission roller assembly 50 is used to guide the pole piece in and out of the installation bin 10.

[0115] The transmission roller assembly 50 refers to a transmission component that provides material transmission for the pole piece. The transmission roller assembly 50 includes a pair of transmission rollers that are arranged opposite to each other, including a first transmission roller 51 and a second transmission roller 52 .

[0116] The transmission roller assembly 50 also includes a driving assembly. Each transmission roller can correspond to a driving assembly. The driving assembly includes a driving member 53 and a connecting rod 54. The driving member 53 is installed on the installation bin 10. The driving member 53 is connected to the first transmission roller 51 or the second transmission roller 52 through the connecting rod 54. The driving member 53 can drive the first transmission roller 51 or the second transmission roller 52 to move along the thickness direction of the pole piece to adjust the gap between the two transmission rollers to meet the material transfer requirements of pole pieces of different sizes.

[0117] In this embodiment, please refer to Figure 1 and Figure 2 The transmission roller assembly 50 is arranged at the feed port 11 and the discharge port 12 of the installation bin 10 , that is, a group of transmission roller assemblies are arranged at the feed port 11 and the discharge port 12 of the installation bin 10 .

[0118] By providing a driving roller assembly 50 at the feed port 11 and / or the discharge port 12 of the installation bin 10 , the driving roller assembly 50 plays the function of transferring materials, which is beneficial for the cleaning and dust removal of the dust on the surface of the pole piece through the installation bin 10 .

[0119] The dust removal device 100 may further include a winding roller assembly 60 , which is disposed on a side of the installation bin 10 close to the discharge port 12 , and is used to wind up the pole piece after cleaning and dust removal.

[0120] The winding roller assembly 60 includes a winding roller 61 and a winding roller bracket 62 . The winding roller 61 is installed on one side of the discharge port 12 of the installation bin 10 through the winding roller bracket 62 . The winding roller 61 is rotatably installed on the winding roller bracket 62 .

[0121] An embodiment of the present application further provides a battery production line, which includes the dust removal device 100 in any of the above embodiments.

[0122] The present application provides a dust removal device, please refer to Figures 1 to 6 , Figure 1 A schematic diagram of the structure of a dust removal device in some embodiments of the present application; Figure 2 A schematic structural diagram of a dust removal device according to some embodiments of the present application from another angle; Figure 3 for Figure 1 A schematic diagram of the structure of the dust removal device after removing the installation bin and the material transfer roller; Figure 4 for Figure 3 A is an enlarged schematic diagram; Figure 5 for Figure 3 A schematic diagram of the structure of the dust collecting component; Figure 6 This is a schematic diagram of the structure of the dust removal device of some embodiments of the present application after the mounting bin and the material transfer roller are removed.

[0123] The dust removal device 100 includes a cleaning assembly 20, a dust collection assembly 30 and an installation bin 10. The cleaning assembly 20 is used to clean the electrode. The cleaning assembly 20 includes two cleaning components 21. A gap is defined between the two cleaning components 21 for the electrode to pass through. The cleaning component 21 includes a substrate 210 and a cleaning brush 211. The substrate 210 is installed on the installation bin 10. The cleaning brush 211 is arranged on the substrate 210. The cleaning brush 211 is used to contact one side of the electrode in the thickness direction. There are multiple cleaning brushes 211, and multiple cleaning brushes 211 are distributed on the substrate 210 at intervals along the width direction and / or length direction of the electrode. The dust collection assembly 30 is arranged on one side of the cleaning assembly 20. The dust collection assembly 30 is used to negatively absorb dust generated during the cleaning process of the cleaning assembly 20. The installation bin 10 is covered with the cleaning assembly 20 and the dust collection assembly 30. The installation bin 10 has a feed inlet 11 and a discharge outlet 12 for the electrode to pass through.

[0124] The two cleaning components 21 are arranged at intervals to form a gap for the pole piece to pass through. The two cleaning components 21 can contact the two sides of the thickness direction of the pole piece respectively, so as to realize double-sided dust removal of the pole piece, improve the dust removal effect of the pole piece, and thus reduce the failure rate of the battery. The installation bin 10 is covered with the cleaning component 20 and the dust collection component 30. The dust removed from the pole piece is confined to a specific space in the installation bin 10. On the one hand, the risk of dust leakage is reduced. On the other hand, the negative pressure area generated by the dust collection component 30 in the relatively closed internal space in the installation bin 10 is larger, which increases the area of ​​the negative pressure adsorption of the dust collection component 30, and is more conducive to the negative pressure airflow generated by the dust collection component 30 to take away the dust floating in the installation bin 10 in time, thereby improving the dust removal effect of the pole piece and reducing the probability of secondary adhesion of dust. The arrangement of multiple cleaning brushes 211 on the substrate 210, and the cooperation of multiple cleaning brushes 211 together can simultaneously clean the area in the length direction and / or width direction of the pole piece surface, with a wide coverage range and higher cleaning efficiency for the pole piece.

[0125] In some embodiments, the cleaning component 21 also includes a position adjustment component 22, which includes an elastic member 220 and a guide rod 221. The elastic member 220 is extended along the thickness direction of the pole piece, and the two ends of the elastic member 220 are respectively connected to the substrate 210 and the installation bin 10. The guide rod 221 is arranged on the substrate 210 along the thickness direction of the pole piece. The guide rod 221 passes through the installation bin 10, and the end of the guide rod 221 located outside the installation bin 10 has a limiting portion 222. The limiting portion 222 is used to make the end of the guide rod 221 away from the substrate 210 be located outside the installation bin 10.

[0126] The two ends of the elastic member 220 are respectively connected to the substrate 210 and the installation bin 10. Under the action of the expansion and contraction deformation of the elastic member 220, the cleaning brushes 211 of the two cleaning components 21 can always contact the two sides of the thickness direction of the pole piece, and the cleaning effect on the pole piece is good. In addition, when dealing with the floating effect during the transmission of the pole piece, or dealing with the cleaning needs of pole pieces of different thicknesses, the elastic member 220 can adaptively deform to adjust the gap between the two cleaning components 21, without human intervention, and the adjustment is simple and has a wide range of applications. The guide rod 221 is inserted into the installation bin 10, and the guide rod 221 can guide the up and down adjustment direction of the cleaning component 21, guide the cleaning component 21 to float up and down relative to the installation bin 10, so that the stability of the up and down movement process of the cleaning component 21 is higher. The limiter 222 can prevent the end of the guide rod 221 away from the substrate 210 from entering the installation bin 10, thereby improving the installation stability of the cleaning component 21.

[0127] In some embodiments, the dust collection assembly 30 includes a dust collection component 31, an air extraction component and a collection bin 32. The dust collection component 31 is disposed on the substrate 210 and located on both sides of the width direction of the pole piece. The dust collection component 31 has a dust collection port 312 facing the cleaning component 21. The air extraction component is connected to the dust collection port 312 through an air extraction pipe. The air extraction component is used to form a negative pressure in the area of ​​the dust collection port 312. The collection bin 32 is connected to the air outlet of the air extraction component. A dust filter is provided at the air outlet of the collection bin 32. The dust filter is used to prevent the dust adsorbed by the dust collection component 31 from being discharged from the air outlet. The collection bin 32 is located outside the installation bin 10.

[0128] In some embodiments, the number of cleaning components 20 is set to two groups, and the two groups of cleaning components 20 are spaced apart in the installation bin 10 along the feeding direction of the electrode, and a material guide roller assembly 40 is arranged between the two groups of cleaning components 20. The material guide roller assembly 40 includes two material guide rollers 41, and the two material guide rollers 41 are respectively rotatably installed on the corresponding substrates 210 of the two cleaning components 21.

[0129] Multiple groups of cleaning components 20 are spaced apart along the feeding direction of the pole piece, so as to realize the cleaning and dust removal of the pole piece one by one and twice, and the dust removal effect of the pole piece is better. The gap between the two oppositely arranged guide rollers 41 can allow the pole piece to pass through. When the two guide rollers 41 can passively rotate along their axial directions, the two guide rollers 41 are in contact with both sides of the thickness direction of the pole piece respectively, providing a bearing effect on the pole piece while guiding the pole piece to pass through the cleaning component 20, reducing the resistance of the pole piece passing through the cleaning component 20, and being more conducive to the pole piece to complete the dust removal operation.

[0130] In some embodiments, the dust removal device further includes a transmission roller assembly and a winding roller assembly 60, the transmission roller assembly is arranged at the feed port 11 and / or the discharge port 12 of the installation bin 10, and the transmission roller assembly is used to guide the pole piece to enter and exit the installation bin 10. The winding roller assembly 60 is arranged on one side of the discharge port 12 of the installation bin 10. The winding roller assembly 60 is used to wind up the pole piece after dust removal and cleaning.
