[0031] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0032] For reference Figure 1 and Figure 2 The utility model provides a battery cell dust removal device 100, comprising a transmission component 10, an electrostatic eliminator 20 and a dust removal component 30. The electrostatic eliminator 20 is arranged adjacent to the transmission component 10. The dust removal component 30 is arranged on the side of the transmission component 10 that is away from the center of the earth, and the electrostatic eliminator 20 and the dust removal component 30 are arranged sequentially in a first direction. Among them, the transmission component 10 is suitable for driving the battery cell 90 to pass through the electrostatic eliminator 20 and the dust removal component 30 sequentially in the first direction, the electrostatic eliminator 20 is suitable for eliminating static electricity on the surface of the battery cell 90, and the dust removal component 30 is suitable for cleaning the dust on the surface of the battery cell 90.

[0033] The static eliminator 20 can be an ion fan, an ion air gun, an ion air rod, an ion air blower, an ion air nozzle, an ion air curtain, a high voltage generator, a board cleaning machine, etc., without limitation.

[0034] The static eliminator 20 is disposed adjacent to the transmission component 10 , that is, the static eliminator 20 can be disposed spaced apart from the transmission component 10 in the first direction or in the second direction, and the first direction intersects the second direction.

[0035] The transmission assembly 10 includes a motor 11 , a roller 12 and a conveyor belt 13 . The motor 11 drives the roller 12 to rotate, and the roller 12 drives the conveyor belt 13 to move the battery cell 90 .

[0036] The battery cell 90 passes through the static eliminator 20 and the dust removal assembly 30 in sequence in the first direction. The static eliminator 20 first sends ions to the surface of the battery cell 90 to neutralize the static electricity on the surface of the battery cell 90 and eliminate the electrostatic adsorption force of the surface of the battery cell 90 on the dust, which is beneficial to improving the working efficiency of the subsequent dust removal assembly 30.

[0037] The battery cell dust removal device 100 of the utility model is provided with an electrostatic eliminator 20, a transmission component 10 and a dust removal component 30. Before the transmission component 10 transports the battery cell 90 to the dust removal component 30 for performing dust removal operation on the battery cell 90, the static electricity on the surface of the battery cell 90 is first eliminated, which can reduce the static adsorption force of the surface of the battery cell 90 on the dust and improve the dust removal ability of the battery cell dust removal device 100.

[0038] For reference Figure 2 and Figure 3 In one embodiment, the static eliminator 20 is connected to the dust removal assembly 30.

[0039] The connection method between the static eliminator 20 and the dust removal assembly 30 can be screw connection, welding, clamping, bonding, etc., without limitation.

[0040] The connection between the static eliminator 20 and the dust removal assembly 30 can improve the integration of the battery cell dust removal device 100, which is beneficial to improving the space utilization of the battery cell dust removal device 100.

[0041] For reference Figure 2 and Figure 3 In one embodiment, the dust removal assembly 30 includes a shell 31 and a brush member 32. The shell 31 has a dust removal chamber 311 and a connecting port 312 connected to the dust removal chamber 311. The brush member 32 is accommodated in the dust removal chamber 311. The connecting port 312 faces the transmission assembly 10. The brush member 32 is suitable for cleaning dust on the surface of the battery cell 90 through the connecting port 312.

[0042] The material of the shell 31 can be metal, high-strength plastic, etc., specifically stainless steel, aluminum alloy, etc., without limitation.

[0043] The dust removal chamber 311 can be spherical, cubic, etc. without limitation.

[0044] The brush member 32 is suitable for brushing dust on the surface of the battery core 90 . Compared with conventional negative pressure suction, the brush member 32 has a better dust removal effect.

[0045] For reference Figure 2 and Figure 3In one embodiment, the brush member 32 includes a rotating shaft 321 and a brush 322, the rotating shaft 321 is rotatably connected to the shell 31, the brush 322 is connected to the rotating shaft 321, and the rotating shaft 321 is suitable for driving the brush 322 to rotate; the dust removal component 30 also includes a cleaning roller 33, the cleaning roller 33 is connected to the shell 31, the cleaning roller 33 is spaced apart from the rotating shaft 321, and the cleaning roller 33 is suitable for colliding with the end of the brush 322 away from the rotating shaft 321 to shake off the dust on the brush 322.

[0046] For reference Figure 1 Optionally, the dust removal assembly 30 further includes a motor 11, which is suitable for driving the rotating shaft 321 to rotate. Specifically, the rotating shaft 321 and the brush 322 rotate at a constant speed counterclockwise, so that the linear velocity direction of the brush 322 in contact with the battery cell 90 is opposite to the movement direction of the battery cell 90.

[0047] There can be multiple brushes 322, and the multiple brushes 322 are arranged at intervals in the circumferential direction of the rotating shaft. The material of the brush 322 can be plastic material, and the specific material of the brush 322 can be nylon, polyester, polypropylene, etc., without limitation. Optionally, the brush 322 and the surface of the battery cell 90 are both made of plastic material.

[0048] The cleaning roller 33 may be made of metal, specifically, stainless steel, aluminum alloy, etc., without limitation. The cleaning roller 33 made of metal has a conductive function and can timely neutralize the static electricity generated by the friction between the brush 322 and the surface of the battery cell 90 .

[0049] The brush member 32 further includes a coupling 323 , which is suitable for connecting the motor 11 and the rotating shaft 321 , so that the motor 11 drives the rotating shaft 321 and the brush 322 to rotate.

[0050] The brush 322 brushes the dust remaining on the surface of the battery cell 90 and lifts it in the opposite direction away from the center of the earth, so as to clean the surface of the battery cell 90 once. The brush 322 and the surface of the battery cell 90 are constantly brushed and rubbed, which easily generates static electricity. The static electricity will absorb fine dust. If it is not cleaned in time, it will pollute the battery cell 90 again. The dust removal assembly 30 of the utility model is provided with a cleaning roller 33. After brushing the battery cell 90, the brush 322 rotates counterclockwise until it collides with the cleaning roller 33 to shake off the dust adhering to the brush 322, thereby improving the self-cleaning ability of the brush 322 and reducing the risk of the brush 322 carrying dust and causing secondary pollution of the battery cell 90.

[0051] For reference Figure 3In one embodiment, the dust removal assembly 30 also includes a receiving tube 34, which is connected to the shell 31. The receiving tube 34 has a receiving cavity 341 and a first opening 342 and a second opening 343 connected to the receiving cavity 341. The first opening 342 and the second opening 343 are spaced apart in the circumferential direction of the receiving tube 34. The receiving cavity 341 receives the brush member 32. The opening directions of the first opening 342 and the connecting port 312 are the same. The cleaning roller 33 is arranged at the second opening 343.

[0052] The first opening 342 and the communication opening 312 have the same opening direction, that is, the first opening 342 and the communication opening 312 both face the transmission assembly 10 and the battery cell 90 .

[0053] The second opening 343 is disposed at one end of the receiving tube 34 close to the housing 31 , and the second opening 343 is disposed at one side of the receiving tube 34 close to the static eliminator 20 .

[0054] The storage tube 34 is suitable for protecting the brush 322 . At the same time, the dust dropped by the collision between the cleaning roller 33 and the brush 322 can escape to the outside of the storage tube 34 through the second opening 343 to avoid falling on the battery cell 90 and causing secondary pollution to the surface of the battery cell 90 .

[0055] For reference Figure 3 In one embodiment, the shell 31 and the receiving tube 34 enclose a first flow channel 313, the shell 31 is provided with a first air outlet 314, the first flow channel 313 is connected to the connecting port 312 and the first air outlet 314, and the first flow channel 313 is located on a side of the receiving tube 34 close to the static eliminator 20.

[0056] Optionally, the dust removal assembly 30 further includes a first dust removal pipe 35, which is connected to the first air outlet 314, and there may be multiple first dust removal pipes 35. The first dust removal pipe 35 is suitable for forming a stable negative pressure suction airflow in the first flow channel 313, so that dust and the like enter the first flow channel 313 from the connecting port 312 to the first air outlet 314, thereby taking away the dust raised by the brush 322. The dust remaining on the large surface of the battery cell 90 has a large adhesion to the surface of the battery cell 90, and conventional negative pressure suction cannot directly remove dust from its intake. The combined effect of the brush 322 and the negative pressure of the first flow channel 313 can brush and clean the compressed dust and raise it, effectively improving the dust removal effect.

[0057] Optionally, the first flow channel 313 is also connected to the second opening 343, and a portion of the negative pressure airflow generated by the first dust removal pipe 35 can flow in through the second opening 343, thereby taking away the suspended dust shaken off after the cleaning roller 33 collides with the brush 322, thereby improving the self-cleaning ability of the brush 322 and reducing the risk of the brush 322 carrying dust and causing secondary contamination of the battery cell 90.

[0058] For reference Figure 3In one embodiment, the dust removal assembly 30 also includes a first baffle 40, which is disposed at the end of the shell 31 near the connecting port 312, and the first baffle 40 extends in a first direction away from the shell 31. The first baffle 40 is located on a side of the receiving tube 34 near the static eliminator 20, and there is a gap between the first baffle 40 and the battery cell 90.

[0059] The first baffle 40 and the shell 31 may be an integral structure, that is, the first baffle 40 and the shell 31 are an integral structure prepared by an integral process, and the integral process may specifically be stamping, casting, etc.; the first baffle 40 and the shell 31 may also be a split structure, that is, the connection method between the first baffle 40 and the shell 31 may be screwing, welding, bonding, clamping, etc., without limitation.

[0060] When the brush 322 brushes the surface of the battery cell 90 at high speed, dust will splash at high speed, causing the dust to escape in the opposite direction of the movement of the battery cell 90. The first baffle 40 and the surface of the battery cell 90 form a first slit, and the airflow required by the first dust removal pipe 35 enters the first flow channel 313 from the slit, forming a stable and high-speed dust removal airflow in the slit. When the dust escapes in the opposite direction of the movement of the battery cell 90, the first baffle 40 can hinder the escape of the dust and make the dust move in the direction of the airflow, thereby avoiding secondary pollution to the transmission component 10, the battery cell 90, etc.

[0061] In one embodiment, the interval between the first baffle 40 and the battery cell 90 is d1, which satisfies: 2mm≤d1≤3mm. Optionally, d1 can be 2mm, 2.4mm, 2.8mm, 3mm, etc., without limitation.

[0062] When d1 is less than 2 mm, the distance between the first baffle plate 40 and the surface of the battery cell 90 is too small, which is not conducive to providing gas to the first flow channel 313, and dust can easily form a blockage between the first baffle plate 40 and the battery cell 90; when d1 is greater than 3 mm, the distance between the first baffle plate 40 and the surface of the battery cell 90 is too large, and it is not easy to produce a slit, and the effect of the airflow on the dust is poor, making it difficult for the dust to flow from the first flow channel 313 to the first outlet; when 2 mm ≤ d1 ≤ 3 mm, the first baffle plate 40 and the surface of the battery cell 90 can form a first slit, and the gas required for the first dust removal pipe 35 to generate a negative pressure airflow can enter the first flow channel 313 from the first slit.

[0063] For reference Figure 3 In one embodiment, the shell 31 and the receiving tube 34 enclose a second flow channel 315, the shell 31 is provided with a second air outlet 316, the second flow channel 315 is connected to the connecting port 312 and the second air outlet 316, and the second flow channel 315 is located on the side of the receiving tube 34 away from the static eliminator 20.

[0064] Optionally, the dust removal assembly 30 further includes a second dust removal pipe 36, which is connected to the second air outlet 316, and there may be multiple second dust removal pipes 36. The second dust removal pipe 36 is suitable for forming a stable negative pressure suction airflow in the second flow channel 315, so that dust and the like enter the second flow channel 315 from the connecting port 312 to the second air outlet 316. Specifically, there are four first dust removal pipes 35 and four second dust removal pipes 36, which are arranged at relative intervals.

[0065] For reference Figure 3 In one embodiment, the dust removal assembly 30 also includes a second baffle 50, which is disposed at the end of the shell 31 near the connecting port 312, and the second baffle 50 extends in a first direction away from the shell 31. The second baffle 50 is located on the side of the receiving tube 34 away from the static eliminator 20, and there is a gap between the second baffle 50 and the battery cell 90.

[0066] The second baffle plate 50 is disposed opposite to the first baffle plate 40 .

[0067] The second baffle plate 50 and the shell 31 may be an integral structure, that is, the second baffle plate 50 and the shell 31 are an integral structure prepared by an integral process, and the integral process may specifically be stamping, casting, etc.; the second baffle plate 50 and the shell 31 may also be a split structure, that is, the connection method between the second baffle plate 50 and the shell 31 may be screwing, welding, bonding, clamping, etc., without limitation.

[0068] Optionally, the interval between the second baffle 50 and the battery cell 90 is d2, which satisfies: 2mm≤d2≤3mm. Optionally, d2 can be 2mm, 2.4mm, 2.8mm, 3mm, etc., without limitation.

[0069] The second baffle 50 and the surface of the battery cell 90 form a second slit, and the airflow required by the second dust removal pipe 36 enters the second flow channel 315 from the slit, forming a stable and high-speed dust removal airflow in the slit. When the dust escapes in the opposite direction of the movement of the battery cell 90, the second baffle 50 can hinder the escape of the dust and make the dust move in the direction of the airflow, thereby avoiding secondary pollution to the transmission component 10, the battery cell 90, etc.

[0070] For reference Figure 2 and Figure 3 In one embodiment, the battery cell dust removal device 100 also includes an ultrasonic exciter 70, which is disposed at the end of the shell 31 close to the connecting port 312, and the ultrasonic exciter 70 is disposed on the side of the shell 31 away from the static eliminator 20, and the ultrasonic exciter 70 is suitable for causing dust to leave the surface of the battery cell 90.

[0071] Optionally, the battery cell dust removal device 100 further includes a mounting member 71, the mounting member 71 is connected to the second baffle 50, the ultrasonic exciter 70 is connected to the mounting member 71, the ultrasonic exciter 70 and the mounting member 71 can be connected by screw connection, welding, etc., and the mounting member 71 and the housing 31 can be connected by welding, screw connection, clamping, etc., without limitation. Specifically, there is an angle between the mounting member 71 and the second baffle 50 and the housing 31, the mounting member 71 and the housing 31 are enclosed to form a receiving groove, and the ultrasonic exciter 70 is received in the receiving groove.

[0072] The ultrasonic exciter 70 may be of piezoelectric, magnetostrictive, electric, etc., without limitation.

[0073] The ultrasonic exciter 70 is suitable for destroying the boundary layer between the dust and the surface of the battery cell 90 by exciting the air, destroying its adsorption force, and causing the fine dust to leave the surface of the battery cell 90. The second baffle 50 and the battery cell 90 form a slit, and the dust enters the second flow channel 315 and flows to the second air outlet 316, taking away the suspended fine dust, achieving secondary cleaning of the surface of the battery cell 90, and ensuring the cleanliness of the surface of the battery cell 90.

[0074] For reference Figure 2 and Figure 3 In one embodiment, the battery cell dust removal device 100 further includes a clamping assembly 80, which is connected to the transmission assembly 10, the clamping assembly 80 is suitable for accommodating the battery cell 90, and the transmission assembly 10 is suitable for driving the clamping assembly 80 to move.
