However, welding will generate a lot of dust, which is mainly fine metal debris, which can easily cause problems such as short circuit of the electrode assembly. Therefore, high-pressure gas or dust removal system is required to remove impurities inside and outside the battery.

[0003] However, most of the existing dust removal systems are used to remove dust from the modules with the electrode terminals of the battery cells in the vertical direction, and cannot effectively remove dust from the modules with the electrode terminals of the battery cells arranged on the side in the horizontal direction after welding.

[0057] The battery includes a plurality of battery cells, and two battery cells are fixedly connected by welding through a current collecting member, so that the plurality of battery cells are connected in series, in parallel or in mixed connection (in series and in parallel).

[0058] In the existing battery processing process, in many cases the electrode terminals of the battery cells are fixedly connected to the collector components by welding. A large amount of dust will be generated during welding. This dust is mainly fine metal oxide dust. This metal oxide dust will be adsorbed on the surface of the battery cells, which may cause risks such as short circuits in the battery cells. In order to reduce the impact of metal oxide dust formed by welding on the safety of the battery cells, it is necessary to use a dust removal system to remove dust from the inside and outside of the battery cells after welding, and then carry out subsequent processes such as cover packaging and electrolyte filling after dust removal. However, the electrode terminals of the battery cells of some battery modules are set on the horizontal side, and the brushes of the dust removal system are set vertically, which makes it impossible for the brushes to remove dust from the battery modules whose electrode terminals of the battery cells are set on the horizontal side.

[0059] Therefore, if Figures 1 to 3 As shown, the present application provides a dust removal system, which can remove dust from the electrode terminals of the battery cell 9 in the horizontal direction by changing the setting direction and movement direction of the brush 1. The present application sets the brush 1 to be connected with the connecting component 2, so that the brush 1 can be driven to rotate and sweep by the driving member 3, and move vertically and horizontally through the moving mechanism, so that the brush 1 can fit with the area to be dusted of the battery module, so as to remove dust from the electrode terminals of the battery cell 9 in the battery module in the horizontal direction, and then the dust is sucked away by the dust removal system, thereby improving the dust removal effect.

[0060] The dust removal system of the embodiment of the present application can be used in a battery production system, and the battery production system includes a welding device and a dust removal system, the welding device is used to weld the battery, and the dust removal system is used to remove dust after the battery is welded. The dust removal system of the present application can be applied to any battery, such as a battery module and a battery pack, or it can be a primary battery, for example, the battery includes a nickel-hydrogen battery, a nickel-cadmium battery, a lead-acid (or lead-acid) battery, a lithium-ion battery, a sodium-ion battery, a polymer battery, etc. This battery is suitable for various electrical devices using batteries, such as mobile phones, portable devices, laptops, battery cars, electric toys, electric tools, electric vehicles, ships and spacecraft, etc. For example, spacecraft include aircraft, rockets, space shuttles and spacecraft, etc.; the battery is used to provide electrical energy for the above-mentioned electrical equipment. And the above-mentioned battery welding can be laser welding, brazing, plasma arc welding, etc.

[0061] The dust removal system of the present application is used in the dust removal process after the welding process in the battery manufacturing process to remove the dust remaining on the battery surface after welding. The dust is mainly metal oxides generated by welding, and also includes impurities such as welding slag. Of course, in some cases, it can also be used to remove dust inside the battery.

[0062] The battery cell 9 may include a lithium-ion battery, a sodium-ion battery, or a magnesium-ion battery. The battery cell 9 may be cylindrical, flat, rectangular, or in other shapes, and the present application embodiment does not limit this. The battery cell 9 is generally divided into three types according to the packaging method: cylindrical battery cells, square battery cells, and soft-pack battery cells, and the present application embodiment does not limit this.

[0063] The battery cell 9 includes two electrode terminals, one of which is a positive electrode and the other is a negative electrode. The electrode terminals can be used to electrically connect to the battery cell assembly in the battery cell 9 to output or input the electrical energy of the battery cell 9.

[0064] The battery cell 9 can be in various shapes and sizes, such as a rectangular parallelepiped, a cylindrical shape, a hexagonal prism shape, etc.

[0065] The electrode terminal and the collector component can be fixedly connected by welding, and the brush 1 of the dust removal system can sweep and remove dust from the electrode terminal and the collector component to remove dust generated by welding.

[0066] like Figure 1 and 3 As shown, in the first aspect, an embodiment of the present application provides a dust removal system, comprising a brush 1 extending in a horizontal direction, the brush 1 being connected via a connecting component 2, a driving member 3 being connected to the connecting component 2 for driving the brush 1 to rotate, a moving mechanism being connected to the connecting component 2 for driving the brush 1 to move so that the brush 1 can move toward an area of ​​the battery module to be dusted, and a dust removal mechanism 4 being connected to the connecting component 2 for sucking the dust raised by the brush 1.

[0067] Optionally, the brush 1 is driven to rotate by the driving member 3, so as to sweep and brush the places where dust removal is required, such as the places where the electrode terminals and the collector components are welded, and lift up the attached dust. The driving member 3 is used to provide power for the brush 1 to rotate and sweep, and the driving member 3 can include any one of a motor, a pneumatic motor, and a hydraulic motor power device.

[0068] The dust removal mechanism 4 is connected to the connecting assembly 2, so that the dust raised by the brush 1 can be sucked away, thereby achieving the purpose of dust removal.

[0069] Optionally, the connection between the brush 1 and the connecting component 2 can be an integral connection, such as welding or riveting, etc.; of course, it can also be a detachable connection, such as a threaded connection or a snap connection, etc.

[0070] Optionally, the area of ​​the battery module to be dusted includes the dust generated at the welding position between the electrode terminal of a certain battery cell and the collector component; of course, it may also be multiple dust areas generated at the welding positions between the electrode terminals of multiple battery cells and multiple collector components; of course, it may also be the dust in other welds; it may also be the dust in the gaps between adjacent battery cells; it may also be the dust generated at other welding positions of the battery module.

[0071] like Figure 3 As shown, the brush 1 is connected to the driving member 3 through the connecting assembly 2. The brush 1 is arranged at the end of the connecting assembly 2. The other end of the connecting assembly 2 is connected to the driving member 3. The driving member 3 drives the brush 1 to rotate. The moving mechanism is used to drive the brush 1 to move so that the brush 1 can move to the position where the battery cell 9 is welded to the collector member. And because the brush 1 extends in the horizontal direction, the end of the brush 1 can clean the battery module whose electrode terminal of the battery cell 9 is set on the side in the horizontal direction. After cleaning the dust, the dust is sucked by the dust removal mechanism 4, thereby realizing the dust removal of the battery module whose electrode terminal of the battery cell 9 is set on the side in the horizontal direction.

[0072] Optionally, two dust removal systems may be provided and placed on both sides of the battery module in the horizontal direction, so that the electrode terminals on both sides of the battery module can be cleaned simultaneously to improve efficiency.

[0073] Optionally, the end of the brush 1 includes a plurality of clusters of brush filaments, and the diameter of each cluster of brush filaments may be between 0.05 and 1 mm.

[0074] like Figure 2 , 3 As shown in FIG. 6 , in some embodiments, the dust removal mechanism 4 includes a dust cover 41 , which is disposed on the outer periphery of the brush 1 to stop dust raised by the brush 1 .

[0075] Since the electrode terminals of the battery cell 9 are arranged on the side in the horizontal direction, some dust is easy to fall when the brush 1 is cleaning the dust. Therefore, a dust cover 41 is provided on the outer cover of the brush 1 to prevent dust from falling on the table of the dust removal system. The dust removal mechanism 4 can reduce dust and improve the dust removal effect by suction.

[0076] like Figure 2 and 3 As shown, in some embodiments, the dust removal mechanism 4 further includes a dust extraction pipe 42, and both ends of the dust extraction pipe 42 are respectively connected to the connecting assembly 2 and the dust cover 41.

[0077] By setting up the dust extraction pipe 42, the dust extraction pipe 42 can introduce negative pressure to extract the dust, and the two ends of the dust extraction pipe 42 are respectively connected to the connecting component 2 and the dust cover 41, thereby providing a stable connection position for the dust cover 41, so that the dust on the dust cover 41 can be sucked through the dust extraction pipe 42, and it is also convenient to fix the dust cover 41 on the periphery of the brush 1.

[0078] Optionally, the dust cover 41 and the dust extraction pipe 42 can be connected in one piece, such as by welding or riveting, or they can be detachably connected, such as by snap-fitting or threading, and the dust extraction pipe 42 and the connecting assembly 2 can be connected in one piece, such as by welding or riveting, or they can be detachably connected, such as by snap-fitting or threading.

[0079] Optionally, the dust extraction pipe 42 includes but is not limited to being made of flexible pipes such as plastic pipes and rubber pipes.

[0080] like Figure 2 , 3 As shown in Figures , 5 and 8, in some embodiments, the dust extraction pipe 42 includes a connecting section 421, one end of which is connected to the connecting component 2; the connecting component 2 includes a connecting rod 21, the end of the connecting rod 21 is fixedly connected to the brush 1, and the other end is connected to the driving member 3, and the connecting rod 21 passes through the connecting section 421.

[0081] By inserting the connecting rod 21 into the connecting section 421, the brush 1 can protrude out of the end of the connecting section 421. In this way, when the driving member 3 drives the brush 1 to rotate, the interference of the connecting section 421 on the brush 1 can be reduced, thereby improving the dust removal effect.

[0082] Optionally, the connecting rod 21 is a rod-shaped structure with a certain length, and the connecting rod 21 can be made of metal materials such as aluminum, aluminum alloy, iron, and steel.

[0083] Optionally, the brush 1 can be fixedly connected to the connecting rod 21 by fasteners such as screws, and of course, it can also be connected by snap-fitting or other means; in some cases, it can also be an integrated connection, such as welding.

[0084] Optionally, the location where the connecting rod 21 is connected to the brush 1 is a hollow structure, and the brush 1 can be removed into the hollow structure and connected to the connecting rod 21 .

[0085] Optionally, the brush 1 includes an insertion section and bristles, the bristles are connected to the insertion section by hot melting, and the insertion section can be inserted into the connecting rod 21.

[0086] like Figures 2 to 4 As shown in FIG. 8 , in some embodiments, the dust extraction pipe 42 includes an air inlet section 422 , which is protruding along one side of the connecting section 421 , and the air inlet section 422 is connected to the connecting section 421 .

[0087] The connecting section 421 is for the connecting rod 21 to pass through, and the connecting rod 21 will occupy a part of the volume inside the connecting section 421. Therefore, the air inlet section 422 is set on one side of the connecting section 421, so that the negative pressure wind in the connecting section 421 enters from the side air inlet section 422 without interfering with the insertion direction of the connecting rod 21, thereby reducing the influence of the wind resistance brought by the connecting rod 21 itself and improving the dust removal effect.

[0088] Optionally, one end of the air inlet section 422 can be connected to a negative pressure device such as a vacuum pump or a vacuum tank through a pipeline, and the negative pressure device sucks the air in the dust extraction pipe 42, so that the dust extraction pipe 42 has a dust suction function.

[0089] like Figure 3 and 4 As shown, in some embodiments, the dust extraction pipe 42 further includes a gradually expanding section 43 , one end of the gradually expanding section 43 is connected to the air inlet section 422 , and the other end is connected to the connecting section 421 .

[0090] The gradually expanding section 43 is gradually expanded from the direction of the air inlet section 422 toward the direction of the connecting section 421, so that the air inlet section 422 and the connecting section 421 are transitionally connected, increasing the amount of negative pressure air entering the connecting section 421, reducing the wind resistance coefficient, and thus improving the dust removal effect.

[0091] Optionally, the gradually expanding section 43 is connected to the air inlet section 422 at a circular opening, and the position where it is connected to the connecting section 421 is a directional opening, which can increase the amount of air entering the air inlet section 422.

[0092] like Figures 2 to 4 As shown in FIG. 9 , in some embodiments, the dust removal system further includes a wind speed component 8, which is used to monitor the wind speed in the dust extraction pipe 42 ; the dust extraction pipe 42 further includes a fixed section 423 , which is fixedly connected to the anemometer, and the fixed section 423 is connected to the air inlet section 422 .

[0093] By providing the wind speed component 8 and inserting the anemometer into the fixed section 423 and connecting with the fixed section 423 , the wind speed of the air inlet section 422 in the dust extraction pipe 42 can be monitored, thereby improving the dust removal effect.

[0094] Optionally, the wind speed component 8 may be an anemometer.

[0095] like Figure 2 , 3 As shown in FIG. 9 , in some embodiments, the wind speed component 8 includes a monitoring pipeline 81 , and the monitoring pipeline 81 extends into the air inlet section 422 , away from the pipe wall of the air inlet section 422 , so that the monitoring data is more accurate.

[0096] The pipe wall of the air inlet section 422 has a resistance coefficient, so the wind flow rate near the pipe wall close to the air inlet section 422 is relatively slow. Therefore, the monitoring pipeline 81 can be extended to the center position of the air inlet section 422 to improve the monitoring accuracy of the wind speed component 8.

[0097] Optionally, the wind speed component 8 also includes a meter head (not shown in the figure) and an air outlet duct 82. A sensor is installed in the meter head. The meter head is connected to the air outlet duct 82 and the monitoring duct 81 respectively. The end of the monitoring duct 81 extends to the center of the air inlet section 422. Negative pressure wind enters the meter head from the monitoring duct 81. The sensor in the meter head can detect the wind speed at this time. Then, the negative pressure wind flows into the air inlet section 422 from the air outlet duct 82, thereby realizing the monitoring of the wind speed by the wind speed component 8.

[0098] Optionally, the wind speed component 8 includes a fixed part, which is fixedly connected to the air outlet pipeline 82 and the monitoring pipeline 81, wherein the air outlet pipeline 82 and the monitoring pipeline 81 pass through the fixed part, and the fixed part is provided with a thread. The fixed part can be inserted into the fixed section 423 and is threadedly connected to the fixed section 423, so that a part of the air outlet pipeline 82 and the monitoring pipeline 81 are located in the dust extraction pipe 42.

[0099] Optionally, the air outlet pipeline 82 and the monitoring pipeline 81 located outside the dust extraction pipe 42 can be connected to the meter head to form a closed loop.

[0100] In some embodiments, Figure 4 , 6 As shown in FIG. 7 , the dust cover 41 is fixed to one end of the connecting section 421 . The dust cover 41 includes a brush curtain. The brush curtain is arranged on the periphery of the brush 1 and is spaced apart from the brush 1 to form a flow channel.

[0101] The brush curtain is arranged on the outer periphery of the brush 1 and is spaced apart from the brush 1 to form a flow channel and thus an air inlet flow channel, so that negative pressure wind can enter the air inlet section 422 through the gap between the brush curtain and the brush 1.

[0125] By setting up the third moving mechanism 7, the third moving mechanism 7 can drive the brush 1 to move in the horizontal direction and perpendicular to the axial direction of the wool line, so that the brush 1 can clean multiple battery cells 9 in the same row; in addition, the dust removal mechanism 4 of the present application can also be adapted to battery modules of different lengths, thereby improving the adaptability of the product.

[0126] Optionally, the third moving mechanism 7 includes a third motor, a third slide and a third slider, and the third slider is connected to the second slide, so that when the third motor drives the third slider to slide along the third slide, it synchronously drives the second moving mechanism 6 to move, and the third slide extends along the horizontal direction and perpendicular to the second slide. Therefore, when the third slider moves, it also drives the brush 1 to move horizontally and perpendicular to the axial direction of the brush 1. In this way, different lengths of battery modules can be cleaned, and at the same time, the welding positions of the electrode terminals and the collector components of multiple battery cells 9 in the same row can also be cleaned.
