Existing dust removal mechanisms are ineffective at removing dust from battery cells, leading to secondary contamination, poor dust removal efficiency, and potential pollution of the workshop environment. Therefore, improvements are needed. Utility Model Content

Each dust removal mechanism includes an air outlet and an air suction unit arranged on both sides of the conveyor line, and the air outlet center surface of at least two of the dust removal mechanisms is adapted to face different areas of the surface of the battery cell to be dusted.

[0007] In the above technical solution, by arranging multiple dust removal stations sequentially along the conveyor line, the dust removal mechanism includes air outlets and suction units located on both sides of the conveyor line. A combination of blowing and suction can be used. The high-speed airflow from the air outlets blows away particles adhering to the surface of the battery cells to be cleaned, reducing the risk of secondary pollution of the battery cells. The negative pressure suction from the suction units collects the particles promptly, reducing dust dispersion and pollution to the workshop environment. Simultaneously, by setting the air outlet center surface of at least two of the dust removal mechanisms to face different areas of the surface of the battery cells to be cleaned, the effective working area of ​​the air outlets can be increased, enhancing the dust removal effect.

[0011] The above technical solution can increase the effective dust removal area of ​​a single air outlet component.

[0012] In some embodiments, the intersection line between the air outlet center surface of the air outlet component and the dust-to-be-cleaned surface of the battery cell is located between the first center line of the dust-to-be-cleaned surface of the battery cell and the corresponding air outlet component, wherein the first center line is parallel to the extension direction of the conveyor line at the corresponding battery cell.

[0013] In some embodiments, the dust removal mechanism includes multiple groups, with the air outlets in two adjacent groups arranged on different sides of the conveyor line, and the air suctions in two adjacent groups arranged on different sides of the conveyor line.

[0014] In some embodiments, a windbreak is provided between two adjacent sets of the dust removal mechanisms.

[0015] In the above technical solution, the airflow of two adjacent dust removal mechanisms can be isolated, reducing mutual interference between the two adjacent dust removal mechanisms, improving the dust removal effect, and reducing secondary interference on the dust-to-be-cleaned surface of the battery cell.

[0016] In some embodiments, each group includes a plurality of the dust removal mechanisms, and the air outlet center surface of the air outlet component in the plurality of dust removal mechanisms in the same group is adapted to face different areas of the dust-to-be-removed surface of the battery cell.

[0017] In some embodiments, each of the dust removal mechanisms corresponds to a dust removal station, and the air outlet and air suction components of the dust removal mechanism are coplanar with the midpoint of the corresponding dust removal station.

[0018] In some embodiments, the air outlet of the air outlet is elongated, and the length of the air outlet is greater than the length of the dust-to-be-cleaned surface of the battery cell.

[0037] In this application, "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two), and "multiple pieces" refers to two or more (including two).

[0038] In this embodiment of the application, the battery cell can be a secondary battery, which refers to a battery cell that can be recharged to activate the active materials and continue to be used after the battery cell has been discharged.

[0039] The battery cell can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and the embodiments of this application are not limited to this.

[0040] Battery cells can be cylindrical, flat, cuboid, or other shapes, and this application embodiment is not limited to any of these. Battery cells are generally classified into three types according to their packaging method: cylindrical battery cells, square battery cells, and pouch battery cells, and this application embodiment is not limited to any of these types either.

[0041] A battery cell includes a casing, electrode components, and electrolyte. The casing houses the electrode components and electrolyte. The electrode components consist of a positive electrode, a negative electrode, and a separator. The battery cell primarily functions by the movement of metal ions between the positive and negative electrode components. The positive electrode includes a positive current collector and a positive active material layer. The positive current collector includes a current collector body and a positive electrode tab. The positive active material layer is coated on the surface of the current collector body, while the positive electrode tab is not coated with the positive active material layer and protrudes from the current collector body.

[0042] The separator can be made of PP (polypropylene) or PE (polyethylene), etc. Furthermore, the electrode assembly can be a wound structure or a stacked structure; the embodiments of this application are not limited to these.

[0043] The technical solutions described in the embodiments of this application are applicable to various electrical devices that use individual battery cells, such as mobile phones, portable devices, laptops, electric vehicles, electric toys, power tools, vehicles, ships, and spacecraft, including aircraft, rockets, space shuttles, and spacecraft. Individual battery cells are used to store or provide electrical energy.

[0044] During the production of battery cells, it is necessary to remove dust from the end faces of the battery cells. In related technologies, there are two main methods for dust removal from the end faces of battery cells. One method is to use a brush to sweep the particles off the end faces of the battery cells. Brush cleaning methods include oscillating brush dust removal, rotating brush dust removal, and rolling brush dust removal. The other method is to remove particles from the surface of the battery cells by blowing air.

[0045] When using a brush to clean the end face of a battery cell, the brush bristles generate debris due to friction on the uneven surface, which may remain on the end face and cause secondary contamination. While using a blower to remove dust from the end face can reduce secondary contamination, the particles blown out are easily airborne and pollute the workshop environment.

[0046] Based on the above considerations, in order to better remove dust from battery cells and reduce pollution to the workshop environment, the applicant, after in-depth research, designed a battery processing equipment, including: a conveyor line and multiple dust removal mechanisms; the conveyor line has multiple dust removal stations arranged in sequence, and the battery cells are suitable for being conveyed between the multiple dust removal stations; the multiple dust removal stations are arranged in sequence along the conveyor line, and the dust removal mechanism includes an air outlet and an air suction unit arranged on both sides of the conveyor line, and the air outlet center surface of at least two dust removal mechanisms is adapted to face different areas of the surface of the battery cell to be dusted.

[0047] In this type of battery processing equipment, multiple dust removal stations are arranged sequentially along the conveyor line. The dust removal mechanism includes air outlets and suction units located on both sides of the conveyor line. A combination of blowing and suction can be used. The high-speed airflow from the air outlets blows away particles attached to the surface of the battery cells to be cleaned, reducing the risk of secondary pollution of the battery cells. The negative pressure suction unit collects the particles in a timely manner, reducing dust dispersion and pollution to the workshop environment. At the same time, by setting the air outlet center surface of at least two dust removal mechanisms to face different areas of the surface of the battery cells to be cleaned, the effective working area of ​​the air outlet can be increased, enhancing the dust removal effect.

[0048] The battery apparatus mentioned in the embodiments of this application may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells connected in series, parallel, or mixed connections via a busbar.

[0049] In some embodiments, a battery cell assembly is typically formed by arranging multiple battery cells.

[0050] As an example, a battery cell assembly can be a battery module, which is formed by arranging and fixing multiple battery cells together to form an independent module. As another example, a battery module can be formed by bundling multiple battery cells together with cable ties.

[0051] In some embodiments, the battery device may be a battery pack, which includes a housing and one or more individual battery cells housed within the housing.

[0052] As an example, the battery cell assembly can be a battery module, and the battery cell assembly can be housed in the housing by fixing the battery module in the housing.

[0053] As an example, battery cell assemblies can also be housed in a housing by directly fixing multiple battery cells to the housing.

[0054] As an example, the enclosure may include a first enclosure and a second enclosure. The first enclosure and the second enclosure are fastened together to form a closed space inside the enclosure to house the individual battery cells. Here, "closed" refers to covering or closing, and can be either sealed or unsealed. The first enclosure may be a top cover or a bottom plate.

[0055] As an example, the enclosure may include a top cover, a frame, and a bottom plate. The top cover and bottom plate are connected to the frame, creating an enclosed space inside the enclosure to house the individual battery cells.

[0056] In some embodiments, the housing may be part of the vehicle's chassis structure. For example, a portion of the housing may be at least a part of the vehicle's floor, or a portion of the housing may be at least a part of the vehicle's crossbeams and longitudinal beams.

[0057] The technical solutions described in the embodiments of this application are applicable to various electrical devices that use battery devices, such as mobile phones, portable devices, laptops, electric vehicles, electric toys, power tools, vehicles, ships, and spacecraft, etc. For example, spacecraft include airplanes, rockets, space shuttles, and spacecraft.

[0058] This application provides an energy storage device including one or more battery clusters to increase the voltage and capacity of the energy storage device. The battery cluster may include multiple battery devices, which are connected in series via a busbar to increase the voltage of the energy storage device. When the energy storage device includes multiple battery clusters, the multiple battery clusters are connected in parallel to increase the capacity of the energy storage device.

[0059] Energy storage devices can be used in energy storage power stations, wind power generation systems, solar power generation systems, mobile power systems, or temporary power supply systems. Energy storage devices can store electrical energy as needed and output it when appropriate. For example, an energy storage device can store electrical energy during off-peak hours and provide power to relevant users or electrical devices during peak hours. The energy storage system provided in this application embodiment can be any power system that requires energy storage devices.

[0060] In some embodiments, the energy storage device is an energy storage container or an energy storage cabinet.

[0061] In some embodiments, the energy storage device may include a cabinet and one or more battery clusters housed within the cabinet.

[0062] In some embodiments, the energy storage device may include modules such as a thermal management module, a main control module, a central control module, a power distribution module, and a fire protection module.

[0063] As an example, the thermal management module may include a liquid cooling unit that supplies coolant to each battery device via piping to regulate the temperature of the individual battery cells.

[0064] As an example, the main control module can serve as the battery management unit for the battery cluster, used to monitor and manage the battery cluster. The main control module can monitor information such as the current, voltage, power, or temperature of the battery cluster. For instance, it can control the charging and discharging current and voltage of the battery cluster. The main control module includes modules such as an auxiliary battery management unit (SBMU) and a fusion switch.

[0065] As an example, the central control module can serve as the battery management unit for an energy storage device, used to monitor and manage the device.

[0066] As an example, a fire protection system includes control panels, detectors, alarm devices, etc., used to detect, alarm, or extinguish fires in energy storage systems.

[0068] The technical solutions described in the embodiments of this application are applicable to various electrical devices that use energy storage devices, such as mobile phones, portable devices, laptops, electric vehicles, electric toys, power tools, vehicles, ships, and spacecraft, etc. For example, spacecraft include airplanes, rockets, space shuttles, and spacecraft. The energy storage device is used to store or provide electrical energy.

[0069] According to some embodiments of this application, such as Figures 1-7As shown, this application provides a battery processing equipment, including: a conveyor line 1 and multiple dust removal mechanisms.

[0070] Conveyor line 1 is used to transport battery cells 12, and conveyor line 1 is used to transport battery cells 12 from one station to the next station.

[0071] The conveyor line 1 includes multiple dust removal stations arranged along the conveying direction. The battery cells 12 are suitable for conveying between the multiple dust removal stations. Each battery cell 12 can pass through multiple dust removal stations in sequence for dust removal.

[0072] Multiple dust removal stations are arranged sequentially along the conveying direction. When the battery cell 12 is stationary, one battery cell 12 can correspond to one dust removal station, or one battery cell 12 can correspond to multiple dust removal stations, or multiple battery cells 12 can correspond to one dust removal station.

[0073] like Figure 1 and Figure 2 As shown, multiple dust removal mechanisms are arranged sequentially along the conveying direction of conveyor line 1. One dust removal station can correspond to one dust removal mechanism, or one dust removal station can correspond to multiple dust removal mechanisms. The distance between two adjacent dust removal stations can be determined according to the dust removal time and the conveying speed of the battery cell 12 to improve the dust removal effect on the battery cell 12.

[0074] The dust removal mechanism includes an air outlet 21 and an air suction unit 22 arranged on both sides of the conveyor line 1.

[0075] The air outlet 21 and the air suction 22 are arranged opposite each other on both sides of the conveyor line 1 to form an "air curtain". The air outlet 21 is responsible for blowing high-pressure airflow onto the dust-to-be-cleaned surface 121 of the battery cell 12 to blow up the dust on the dust-to-be-cleaned surface 121 of the battery cell 12; the air suction 22 is responsible for sucking up the blown dust to prevent the dust from spreading everywhere and reduce the pollution to the workshop working environment.

[0076] The number of dust removal mechanisms can be determined based on the airflow intensity of the air outlet 21, the specifications of the battery cell 12, and the delivery time. For example, there can be two, four, or more dust removal mechanisms.

[0077] The air outlet component 21 can be an air outlet assembly or a high-pressure fan assembly, and may include components such as an air outlet duct, a motor, and an air outlet. The suction component 22 may include components such as a suction motor, a suction port, and a suction duct.

[0078] The air outlet 21 can be an air knife to blow out high-pressure airflow.

[0079] like Figure 3 and Figure 4As shown, the air outlet center surface 211 of the air outlet component 21 in at least two dust removal mechanisms is adapted to face different areas of the dust removal surface 121 of the battery cell 12, which can increase the effective working area of ​​the air outlet component 21 on the dust removal surface 121 and enhance the dust removal effect.

[0080] It should be noted that the air outlet of the air outlet component 21 is a surface with length and width, and the center of the air outlet is located on the air outlet center surface 211 of the air outlet component 21. The cross-section of the airflow blown out of the air outlet component 21 should also be a surface with length and width, and the center of the cross-section of the airflow blown out of the air outlet component 21 should also be located on the air outlet center surface 211. For clarity, only the air outlet center surface of the air outlet component 21 is shown in the figure.

[0081] The surface 121 of the battery cell 12 to be cleaned can be different areas of the battery cell 12. For example, the surface 121 of the battery cell 12 to be cleaned can be the end face, the side face, or a combination of the outer surface of the battery cell 12. In this embodiment, the surface 121 of the battery cell 12 to be cleaned can be the end face of the battery cell 12.

[0082] The surface 121 of the battery cell 12 to be cleaned can be in various combinations. For example, the surface 121 of the battery cell 12 to be cleaned can be a plane, an arc surface, or a combination of a plane and an arc surface.

[0083] In at least two dust removal mechanisms, the air outlet center surface 211 of the air outlet component 21 is adapted to face different areas of the dust removal surface 121 of the battery cell 12, which can be achieved in at least the following three ways:

[0084] Firstly, such as Figure 5 As shown, the center height of the air outlet center surface 211 of the air outlet component 21 in at least two dust removal mechanisms is different.

[0085] In this embodiment, the center heights of the air outlets of the air outlets of the air outlet components 21 in at least two dust removal mechanisms are different, the air outlet components 21 are set at different heights, and the air outlet center surfaces 211 of the at least two air outlet components 21 are parallel to or have partially non-overlapping areas with the intersection lines of the air outlet center surfaces 211 and the dust-to-be-cleaned surfaces 121 of the battery cell 12.

[0086] The air outlet center surface 211 of at least two air outlets 21 in the multiple dust removal mechanisms is adapted to face different areas of the dust removal surface 121 of the battery cell 12, thereby increasing the total effective dust removal area of ​​the multiple air outlets 21 on the dust removal surface 121 and enhancing the dust removal effect.

[0087] Secondly, such as Figure 6As shown, the line of intersection between the air outlet center surface 211 of the air outlet component 21 and the dust-to-be-cleaned surface 121 of the battery cell 12 forms an acute angle with the first center line of the dust-to-be-cleaned surface 121 of the battery cell 12. The first center line is parallel to the extension direction of the conveyor line 1 at the corresponding battery cell 12.

[0088] like Figure 6 As shown, the horizontal line passing through the center of cell 12 is the first center line.

[0089] In this embodiment, the air outlet of the air outlet 21 is not directly facing the dust-to-be-cleaned surface 121 of the battery cell 12, but the air outlet of the air outlet 21 is inclined, which can increase the effective dust removal area of ​​a single air outlet 21.

[0090] The air outlet component 21 can rotate 5° to 30° around its central axis, for example, 10°, 15° or 20°, to increase the coverage area of ​​the airflow. The central axis of the air outlet component 21 is parallel to the air outlet direction of the air outlet component 21.

[0091] Third, the center heights of the air outlet center surface 211 of the air outlet component 21 in at least two dust removal mechanisms are different, and the intersection line of the air outlet center surface 211 of the air outlet component 21 and the dust removal surface 121 of the battery cell 12 forms an acute angle with the first center line of the dust removal surface 121 of the battery cell 12.

[0092] In this embodiment, the center heights of the air outlets of the air outlets of the air outlet components 21 in at least two dust removal mechanisms are different, that is, at least two air outlet components 21 are set at different heights and are set to rotate at the same target angle. This can increase the effective dust removal area of ​​a single air outlet component 21 and increase the total effective dust removal area of ​​multiple air outlet components 21 on the dust removal surface 121, thereby enhancing the dust removal effect.

[0093] In at least two dust removal mechanisms, the air outlet center surface 211 of the air outlet component 21 is adapted to face different areas of the dust removal surface 121 of the battery cell 12. For example, the intersection line of the air outlet center surface 211 of two adjacent air outlet components 21 with the dust removal surface 121 of the battery cell 12 is located on one side of the first center line of the dust removal surface 121 of the battery cell 12, and the center of the two intersection lines is at a different vertical distance from the first center line of the dust removal surface 121 of the battery cell 12; or the intersection line is located on both sides of the first center line of the dust removal surface 121 of the battery cell 12.

[0094] In this embodiment, as Figure 4As shown, the battery cell 12 moves along conveyor line 1. When the battery cell 12 reaches the first dust removal station, the air outlet 21 and suction 22 of the first dust removal mechanism start working to remove dust from area A of the battery cell 12. The battery cell 12 continues to move and reaches the second dust removal station, where the air outlet 21 and suction 22 of the second dust removal mechanism start working to remove dust from area B of the battery cell 12. The battery cell 12 continues to move and reaches the third dust removal station, where the air outlet 21 and suction 22 of the third dust removal mechanism start working to remove dust from area C of the battery cell 12. The battery cell 12 continues to move and reaches the fourth dust removal station, where the air outlet 21 and suction 22 of the fourth dust removal mechanism start working to remove dust from area D of the battery cell 12. This process is repeated until the battery cell 12 passes through all the dust removal stations in sequence, completing the comprehensive dust removal. After dust removal, the battery cell 12 is transported to the next process for further processing.

[0095] Among them, the sum of areas A, B, C and D covers the entire dust removal area to complete the comprehensive dust removal of the dust removal area of ​​battery cell 12.

[0096] According to the battery processing equipment provided in the embodiments of this application, multiple dust removal stations are arranged sequentially on the conveyor line 1. The dust removal mechanism includes an air outlet 21 and a suction unit 22 disposed on both sides of the conveyor line 1. The equipment can adopt a combination of blowing and suction. The high-speed airflow of the air outlet 21 blows away the particles attached to the dust-to-be-removed surface 121 of the battery cell 12, reducing the risk of secondary pollution of the battery cell 12. The suction unit 22 collects the particles in a timely manner by negative pressure suction, reducing the dust from spreading and reducing the pollution to the workshop working environment. At the same time, by setting the air outlet center surface 211 of the air outlet 21 in at least two dust removal mechanisms to be adapted to face different areas of the dust-to-be-removed surface 121 of the battery cell 12, the effective working surface area of ​​the air outlet 21 on the dust-to-be-removed surface 121 can be increased, enhancing the dust removal effect.

[0097] According to some embodiments of this application, such as Figure 4 and Figure 6 As shown, the intersection line of the air outlet center surface 211 of the air outlet component 21 and the dust-to-be-cleaned surface 121 of the battery cell 12 is located between the first center line of the dust-to-be-cleaned surface 121 of the battery cell 12 and the corresponding air outlet component 21.

[0098] The first center line is parallel to the extension direction of the conveyor line 1 at the corresponding battery cell 12, and passes through the center of the battery cell 12. For example, the first center line of the end face of the cylindrical battery cell 12 is the diameter of the end face of the cylindrical battery cell 12.

[0099] In this embodiment, the air outlet of the air outlet 21 faces the dust-to-be-cleaned surface 121 of the battery cell 12, and the first center line facing the dust-to-be-cleaned surface 121 of the battery cell 12 is between the corresponding air outlet 21.

[0100] The intersection line between the air outlet center surface 211 of the air outlet component 21 and the dust-to-be-cleaned surface 121 of the battery cell 12 is the initial position where the air outlet center surface 211 of the air outlet component 21 reaches the dust-to-be-cleaned surface 121 and begins dust removal. The area between the intersection line and the suction component 22 on the dust-to-be-cleaned surface 121 is the effective dust removal area of ​​the dust removal mechanism.

[0101] According to some embodiments of this application, such as Figure 2 and Figure 4 As shown, the dust removal mechanism includes multiple sets, with the air outlet 21 in two adjacent sets arranged on different sides of the conveyor line 1, and the air suction 22 in two adjacent sets arranged on different sides of the conveyor line 1.

[0102] In other words, the intersection line of the air outlet center surface 211 of the air outlet component 21 in two adjacent groups with the dust removal surface 121 of the battery cell 12 is located on different sides of the first center line of the corresponding dust removal surface 121 of the battery cell 12.

[0103] One set of dust removal mechanisms may include a pair of air outlets 21 and air suction units 22, or multiple pairs of air outlets 21 and air suction units 22, with the air outlets 21 and air suction units 22 arranged on both sides of the conveyor line 1.

[0104] The dust removal mechanism may include at least two or more sets, which can be determined according to the air outlet intensity of the air outlet 21, the specifications of the battery cell 12, and the delivery time.

[0105] In this embodiment, the air outlets 21 located on different sides of the conveyor line 1 are directed toward different areas of the dust-removing surface 121 of the battery cell 12, so as to increase the total effective dust removal area of ​​the multiple dust removal mechanisms and improve the dust removal effect.

[0106] According to some embodiments of this application, such as Figure 3 and Figure 4 As shown, a windbreak 24 is provided between two adjacent dust removal mechanisms.

[0107] In this embodiment, the air outlets 21 of two adjacent groups are arranged on different sides of the conveyor line 1, that is, the air outlets 21 and the suction units 22 of two adjacent groups have opposite air directions. By providing a baffle 24 between two adjacent dust removal mechanisms, the airflow of the two adjacent dust removal mechanisms can be isolated, reducing the mutual interference between the two adjacent dust removal mechanisms, improving the dust removal effect, and reducing the secondary interference of the dust removal surface 121 of the battery cell 12.

[0108] Among them, the wind deflector 24 can be a wind deflector plate, and the wind deflector 24 is provided with a clearance position. The clearance position is used to avoid the conveyor line 1 and the battery cell 12 located on the conveyor line 1, so as to reduce the impact on the conveyor line 1 conveying the battery cell 12.

[0109] The size and shape of the windbreak 24 need to be determined according to the structure and layout of the dust removal mechanism and the specifications of the conveyor line 1.

[0110] According to some embodiments of this application, such as Figure 6 As shown, each group includes multiple dust removal mechanisms. Among the multiple dust removal mechanisms in the same group, the air outlet center surface 211 of the air outlet component 21 is adapted to face different areas of the dust removal surface 121 of the battery cell 12, which can increase the total effective area of ​​the multiple air outlet components 21 on the dust removal surface 121 and enhance the dust removal effect.

[0111] Among them, the total effective working surface of the multiple air outlets 21 of the multiple dust removal mechanisms covers the dust-to-be-removed surface 121 of the battery cell 12.

[0112] Among the multiple dust removal mechanisms in the same group, the center of the air outlet center surface 211 of the air outlet component 21 is located at different heights.

[0113] According to some embodiments of this application, such as Figure 2 and Figure 3 As shown, each dust removal mechanism corresponds to a dust removal station, and multiple dust removal mechanisms are set up one-to-one with multiple dust removal stations. A single battery cell 12 passes through multiple dust removal stations in sequence, and the single battery cell 12 is dusted by multiple dust removal mechanisms in sequence.

[0114] In this embodiment, matching the movement mode of the dust removal mechanism with that of the conveyor line 1 can not only improve the air volume utilization rate, but also effectively remove dust and quickly collect dust from the dust-to-be-dust-removed surface 121 of the battery cell 12.

[0115] The air outlet 21 and the air suction 22 of the same dust removal mechanism are coplanar with the midpoint of the corresponding dust removal station. That is, the center of the air outlet center surface 211 of the air outlet 21 and the center of the air outlet of the air suction 22 are coplanar with the midpoint of the corresponding dust removal station.

[0116] When a battery cell 12 is placed at the dust removal station, the center of the dust removal station is collinear with the center of the corresponding battery cell 12.

[0117] In this embodiment, when the battery cell 12 is stationary, the battery cell 12 is located between the air outlet of the air outlet 21 and the air inlet of the air intake 22, and is located directly below the air outlet of the air outlet 21, which can make full use of the air volume and further improve the dust removal effect.

[0118] According to some embodiments of this application, such as Figure 6As shown, the air outlet of the air outlet 21 is elongated, which can make the cross-section of the air outlet center surface 211 elongated, increase the wind speed, and extend the length of the intersection line between the air outlet center surface 211 of the air outlet 21 and the dust-to-be-cleaned surface 121 of the battery cell 12.

[0119] The length of the air outlet is greater than the length of the dust-removing surface 121 of the battery cell 12.

[0120] In this embodiment, the length of the air outlet is greater than the length of the first center line of the dust-removing surface 121 of the battery cell 12, so that the width of the air outlet center surface 211 of the air outlet 21 is greater than the dust-removing surface 121 during the process of reaching the dust-removing surface 121 and moving towards the suction component 22, thereby increasing the effective dust removal area and improving the dust removal effect.

[0121] According to some embodiments of this application, such as Figure 1 and Figure 2 As shown, it also includes: a windshield 23, which is suitable for being installed above the dust removal station.

[0122] The wind shield 23 is used to block the dust blown up by the air outlet 21, reducing the dust from spreading and reducing pollution to the workshop working environment.

[0123] The windshield 23 is open at both ends along the conveying direction to allow the conveyor line 1 to pass through.

[0124] The bottom of the windshield 23 is open so that it can be installed above the dust removal station.

[0125] The dust removal mechanism is connected to the windshield 23.

[0126] In this embodiment, the wind deflector 23 includes two side walls located on both sides of the conveyor line 1 and a top wall located above the conveyor line 1. The air outlet 21 and the air suction 22 of the dust removal mechanism can be connected to the two side walls of the wind deflector 23 respectively.

[0127] The dust removal mechanism can be connected to the baffle 23 by welding, plugging or other connection structures. When the baffle 23 is installed above the dust removal station, the air outlet 21 and the air suction 22 of the dust removal mechanism are respectively located on both sides of the conveyor line 1.

[0128] According to some embodiments of this application, such as Figure 7 As shown, the windshield 23 forms a dust removal chamber 232, and the dust-to-be-cleaned surface 121 of the battery cell 12 is adapted to extend into the dust removal chamber 232. The dust removal chamber 232 provides a confined space for the dust-to-be-cleaned surface 121 of the battery cell 12, which helps the dust removal mechanism to perform centralized and more efficient dust removal operations.

[0129] The air outlet 21 is installed on the windshield 23, which allows the airflow blown out from the air outlet 21 to directly enter the dust removal chamber 232 to clean the dust-to-be-cleaned surface 121 of the battery cell 12.

[0130] For example, the air outlet 21 (air blowing device or jet nozzle) is installed inside the windshield 23, and the windshield 23 is provided with a vent hole that connects with the air inlet of the air outlet 21; or, the air outlet 21 (air blowing device or jet nozzle) is installed outside the windshield 23, and the windshield 23 is provided with a vent hole that connects with the air outlet of the air outlet 21.

[0131] The wind deflector 23 has a through hole 231 that communicates with the dust removal chamber 232. The suction port of the suction component 22 is connected to the through hole 231, thereby forming an airflow channel. During the dust removal process, the airflow channel may be used to suck away the dust particles and other pollutants blown up in the dust removal chamber 232, so as to reduce the dust from spreading and reduce the pollution to the workshop working environment.

[0132] According to some embodiments of this application, such as Figures 1-7 As shown, this application provides a battery processing equipment, including a conveyor line 1, a cup 11, a battery cell 12, a windshield 23, a wind deflector 24, an air outlet 21 labeled A, an air outlet 21 labeled B, an air outlet 21 labeled C, an air outlet 21 labeled D, a suction component 22 labeled A corresponding to the air outlet 21 labeled A, a suction component 22 labeled B corresponding to the air outlet 21 labeled B, a suction component 22 labeled C corresponding to the air outlet 21 labeled C, and a suction component 22 labeled D corresponding to the air outlet 21 labeled D. The four air outlets 21 are divided into two groups, and the two groups of air outlets 21 are respectively arranged on both sides of the windshield 23. The center heights of the air outlet center surfaces 211 of the two air outlets 21 in each group are different. The air outlets 21 labeled A and D, located near the edge, are positioned higher, while those labeled B and C are positioned lower. This allows the air outlet center surface 211 of each air outlet 21 to be positioned facing different areas of the dust-to-be-cleaned surface 121 of the battery cell 12. Because the air outlets of the air outlets 21 are elongated, the position where the air outlets 21 blow air onto the end face of the battery cell 12 is fixed and limited. To ensure that the high-velocity area completely covers the end face of the battery cell 12, this invention rotates each air outlet 21 by 15° along its axis, with the rotation effect as follows: Figure 6 As shown in the diagram, the position of the air outlet 21 relative to the end face of the battery cell 12 indicates that after the air outlet 21 rotates, when the battery cell 12 moves through the dust removal device, the high-speed zone can completely cover the end face of the battery cell 12, greatly improving the dust removal efficiency.

[0133] In actual production, the battery cell 12 is placed in the cup 11 and moves intermittently with the conveyor line 1. When the battery cell 12 moves, with the cooperation of the dust removal mechanism and dust removal station, the high wind speed can cover the end face of the battery cell 12, removing surface particles from the surface 121 to be dusted; when the battery cell 12 is stationary, its center position is directly opposite the center of the air outlet 21 and the air suction port of the suction component 22, further removing particles. Under the shielding of the wind deflector 23 and the suction action of the air suction port of the suction component 22, the particles are collected.

[0134] Unless otherwise specified, all embodiments and optional embodiments of this application can be combined to form new technical solutions.

[0135] Unless otherwise specified, all technical features and optional technical features of this application may be combined to form new technical solutions.

[0136] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
