[0041] Please refer to Figure 1 Combination Figure 2 and Figure 3 Some embodiments of the present application provide a battery pole piece cleaning device. The battery pole piece cleaning device includes a cleaning assembly 100, and the cleaning assembly 100 includes a cover body 110, a brush 120, and a driving member (not shown). The brush 120 is disposed in the cover body 110, and a dust suction port 101 is provided on one side of the cover body 110. The battery pole piece 200 is located outside the dust suction port 101. The brush 120 partially extends out of the dust suction port 101 along its own radial direction to contact the battery pole piece 200. During the rotation process of the brush 120 driven by the driving member, the part of the brush 120 extending out of the dust suction port 101 can brush off the dust and foreign matter on the battery pole piece 200, thereby achieving the purpose of cleaning the battery pole piece 200.

[0042] The cleaning assembly 100 further includes a clamping mechanism 130, and a clamping mechanism 130 is provided at each end of the rotating shaft 121 of the brush 120. Figure 1 , Figure 4 and Figure 5 The clamping mechanism 130 includes a clamping shaft 131 and a clamping plate 132. The clamping shaft 131 is rotatably connected to the cover body 110. A clamping groove 133 is provided at one end of the clamping shaft 131. The clamping shaft 131 is also provided with an opening 134 in a radial direction thereof. The clamping plate 132 is connected to the clamping shaft 131 and can move relative to the clamping shaft 131 to cover or expose the opening 134.

[0043] The opening 134 is connected to the card slot 133. When the chuck 132 exposes the opening 134, the end of the rotating shaft 121 can move into or out of the card slot 133 from the opening 134 of the corresponding card connection mechanism 130 in the radial direction. When the chuck 132 covers the opening 134, the chuck 132 and the groove wall of the card slot 133 form a non-circular hole 135, and the end of the rotating shaft 121 is adapted to the non-circular hole 135 of the corresponding card connection mechanism 130, so that the end of the rotating shaft 121 and the corresponding card connection mechanism 130 can rotate synchronously. At the same time, because the chuck 132 covers the opening 134, it can prevent the end of the rotating shaft 121 from moving out of the card slot 133 from the opening 134, and realize the reliable assembly of the end of the rotating shaft 121 and the card connection mechanism 130.

[0044] The driving member is connected to one end of the clamping shaft 131 away from the rotating shaft 121 to drive the clamping shaft 131 to rotate, so that the clamping shaft 131 drives the chuck 132 and the rotating shaft 121 to rotate synchronously. Specifically, the driving member can be connected to the clamping shaft 121 of any clamping mechanism 130 of the two clamping mechanisms 130, and can drive the clamping shaft 121 to rotate.

[0045] In the battery pole piece cleaning device described above, a clamping mechanism 130 is respectively provided at both ends of the rotating shaft 121 of the brush 120, and the clamping shaft 121 of the clamping mechanism 130 is rotatably connected to the cover body 110, and the driving member can drive the clamping shaft 121 to rotate. When the chuck 132 covers the opening 134, the chuck 132 and the groove wall of the clamping groove 133 form a non-circular hole 135, and the end of the rotating shaft 121 is adapted to the corresponding non-circular hole 135 of the clamping mechanism 130, so that the driving member can drive the brush 120 to rotate synchronously through the clamping mechanism 130 to clean the battery pole piece 120. When the chuck 132 exposes the opening 134, the end of the rotating shaft 121 can be radially moved into or out of the slot 133 from the opening 134 of the corresponding clamping mechanism 130, thereby facilitating the assembly of the brush 120 to the clamping mechanism 130 or disassembly from the clamping mechanism 130, and indirectly facilitating the installation of the brush 120 to the driving member or disassembly from the driving member, thereby facilitating the maintenance and replacement of the brush 120 and helping to improve production efficiency.

[0046] In some embodiments, the clamping shaft 131 and the cover body 110 may be rotatably connected via a bearing (not shown).

[0047] In some embodiments, the driving member may be a motor, or other power member capable of driving the card shaft to rotate.

[0048] In some embodiments, the driving member is located outside the housing 110. The end of the clamping shaft 131 connected to the driving member, which is away from the rotating shaft 121, extends out of the housing 110, so as to facilitate connection with the driving member. The end of the clamping shaft 131 connected to the rotating shaft 121 and the chuck 132 are located inside the housing 110, so as to facilitate connection with the rotating shaft 121.

[0049] Combination Figure 4 and Figure 5 In some embodiments, when the chuck 132 covers the opening 134, the non-circular hole 135 formed by the chuck 132 and the slot wall of the slot 133 is a square hole, such as a rectangular hole or a square hole. Since the end of the rotating shaft 121 is adapted to the non-circular hole 135 of the corresponding clamping mechanism 130 (adapted in shape and size), the end of the rotating shaft 121 corresponding to the square hole is also square, so that the end of the rotating shaft 121 and the corresponding clamping mechanism 130 can rotate synchronously.

[0050] In other embodiments, the non-circular hole may also be a hole of other shapes such as a triangle, a pentagon, a hexagon, etc. The non-circular hole only needs to have a non-circular feature so that the end of the rotating shaft and the corresponding clamping mechanism can rotate synchronously.

[0051] In some embodiments, the clamping mechanism 130 includes an elastic member (not shown), the clamping disc 132 and the clamping shaft 131 are respectively connected to the elastic member, and the elastic force of the elastic member is used to drive the clamping disc 132 to move from a position exposing the opening 134 to a position covering the opening 134 .

[0052] When the chuck 132 needs to expose the opening 134, an external force can be applied to the chuck 132 to overcome the elastic force of the elastic member, so that the chuck 132 can move from the position of covering the opening 134 to the position of exposing the opening 134. After the external force is removed, the elastic restoring force of the elastic member itself can drive the chuck 132 to move from the position of exposing the opening 134 to the position of covering the opening 134. By providing the elastic member, the chuck 132 can be easily switched between the position of exposing the opening 134 and the position of covering the opening 134.

[0053] Without applying additional external force, the elastic force of the elastic member can keep the chuck 132 in the position of covering the opening 134 at all times, thereby preventing the end of the rotating shaft 121 from moving out of the slot 133, which is beneficial to ensure the reliable assembly of the rotating shaft 121 and the clamping mechanism 130.

[0054] In some embodiments, the chuck 132 is sleeved on the shaft 131 and can move relative to the shaft 131 along the axial direction of the shaft 131 to cover or expose the opening 134. In this embodiment, the position where the chuck 132 covers the opening 134 and the position where the chuck 132 exposes the opening 134 are two translation positions switched along the axial direction of the shaft 131.

[0055] Specifically, a flange can be set on the outer peripheral surface of the chuck shaft, one end of the elastic member is connected to the flange, and the other end is connected to the chuck, so that the elastic member can apply an elastic force between the chuck shaft and the chuck, so that the elastic force of the elastic member can drive the chuck to move from a position exposing the opening 134 to a position covering the opening 134.

[0056] In some other embodiments, the chuck can rotate relative to the chuck shaft around a first axis to cover or expose the opening. The first axis is perpendicular to the axial direction of the chuck shaft. In this embodiment, the position of the chuck covering the opening and the position of the chuck exposing the opening are two rotation positions that are switched by rotating around the first axis.

[0057] Specifically, the chuck and the chuck shaft can be connected to rotate about the first axis. A torsion spring is used as the elastic member. The torsion spring is arranged at the rotation connection between the chuck and the chuck shaft, so that an elastic force can be applied between the chuck shaft and the chuck by the torsion spring, so that the elastic force of the torsion spring can drive the chuck to rotate from a position exposing the opening to a position covering the opening.

[0058] Please combine Figure 1 and Figure 2 In some embodiments, the cover 110 is provided with a dust outlet (not shown). When the brush 120 cleans the dust and foreign matter on the battery pole piece 200 during the rotation process, the dust and foreign matter brushed off from the battery pole piece 200 are rolled into the cover 110 by the brush 120 and can be discharged from the dust outlet.

[0059] The cleaning assembly 100 further includes a filter plate 140 , which is connected to the cover body 110 and covers the dust exhaust port. The filter plate 140 is provided with a plurality of filter holes 141 .

[0060] Since the filter plate 140 covers the dust outlet, the dust and foreign matter brushed off the battery pole piece 200 are drawn into the cover body 110 by the brush 120 and can be filtered by the filter holes 141 on the filter plate 140 before being discharged through the dust outlet, thereby filtering out larger foreign matter and preventing the larger foreign matter from clogging the dust outlet pipe connected to the dust outlet.

[0061] In some embodiments, the cleaning assembly 100 further includes a dust exhaust pipe (not shown), one end of which is connected to the cover body 110 , and the other end of which is used to connect to a dust suction mechanism so that the dust suction mechanism can suck away dust in the cover body 110 through the dust exhaust pipe.

[0062] Specifically, one end of the dust exhaust pipe can be connected to the dust exhaust port on the cover body 110, so that the dust in the cover body 110 can be sucked away by the dust suction mechanism after passing through the dust exhaust port and the dust exhaust pipe.

[0063] In some embodiments, the cleaning assembly 100 further includes a dust collecting chamber (not shown), which is connected to the housing 110. The dust collecting chamber has an inlet at one end and an outlet at the other end. The inlet of the dust collecting chamber is connected to the dust exhaust port of the housing 110, and the outlet of the dust collecting chamber is used to connect to the dust exhaust pipe, so that the dust in the housing 110 can enter the dust exhaust pipe only after being collected by the dust collecting chamber. One end of the dust exhaust pipe is connected to the outlet of the dust collecting chamber, so that it can be connected to the dust exhaust port of the housing through the dust collecting chamber.

[0064] From the entrance to the exit of the dust collecting chamber, the interior of the dust collecting chamber is gradually reduced, that is, the entrance of the dust collecting chamber is relatively large, and gradually becomes smaller from the entrance to the exit. In this way, the dust in the cover body 110 can easily enter the dust collecting chamber from the relatively large entrance. After the dust enters the dust collecting chamber, due to its gradually reduced setting, the dust gradually gathers at the exit of the dust collecting chamber, thereby facilitating the dust collection to the dust exhaust pipe.

[0065] Please combine Figures 1 to 3 In some embodiments, the cover body 110 includes two end plates and a plurality of side plates connected in sequence, and the two ends of the side plates are respectively connected to the two end plates. The clamping shafts 131 of the two clamping mechanisms 130 are respectively rotatably connected to the two end plates.

[0066] Please combine Figures 1 to 3 In some embodiments, the two end plates are respectively a first end plate 111 and a second end plate 112 which are arranged opposite to each other. The plurality of side plates include a side plate located at the top of the cover body 110 (hereinafter referred to as the top side plate 113) and a side plate located at the bottom of the cover body 110 (hereinafter referred to as the bottom side plate 114). The top side plate 113 and the bottom side plate 114 are arranged opposite to each other. The top side plate 113, the bottom side plate 114 and the two end plates form a dust suction port 101.

[0067] exist Figure 1 In the embodiment shown, there are three side panels in total, and the top side panel 113 and the bottom side panel 114 are connected by a side panel (hereinafter referred to as a connecting side panel 115). The top of the connecting side panel 115 is connected to the top side panel 113, and the bottom of the connecting side panel 115 is connected to the bottom side panel 114.

[0068] In other embodiments, the top side plate and the bottom side plate may be connected by two, three or more side plates. The total number of side plates may also be four, five or more.

[0069] Please combine Figures 1 to 3 In some embodiments, the dust outlet is provided on the side plate, and a mounting groove 102 is formed between the side plate provided with the dust outlet and the two end plates, and the mounting groove 102 is used for inserting the filter plate 140. In this way, when installing the filter plate 140, it is only necessary to insert the filter plate 140 into the mounting groove 102, so that the filter plate 140 can be installed between the side plate provided with the dust outlet and the two end plates, thereby covering the dust outlet, and facilitating the installation and positioning of the filter plate 140.

[0070] exist Figure 1 In the illustrated embodiment, the dust exhaust port is provided on the bottom side plate 114. The limiting groove 102 is provided between the bottom side plate 114 and the two end plates.

[0071] In other embodiments, the dust exhaust port may also be provided on other side panels except the bottom side panel.

[0072] In some embodiments, a groove is provided at one end of the end plate facing the side plate provided with the dust exhaust port, and the side plate provided with the dust exhaust port and the groove wall of the groove together form a mounting groove 102. In this embodiment, by providing a groove at one end of the end plate facing the side plate provided with the dust exhaust port, the side plate provided with the dust exhaust port and the groove wall of the groove together form a mounting groove 102. In this way, the mounting groove 102 is conveniently formed, and the end surface of the end plate provided with the groove can be closely attached to the side plate provided with the dust exhaust port, so as to facilitate the connection between the side plate provided with the dust exhaust port and the end plate.

[0073] exist Figure 1 In the illustrated embodiment, the side plate with the dust outlet is the bottom side plate 114 , and a groove is provided at one end of the end plate facing the bottom side plate 114 . The bottom side plate 114 and the groove wall of the groove together form the installation groove 102 .

[0074] refer to Figure 2 and Figure 3 In some embodiments, the cover 110 further includes a baffle 116, and one end of the bottom side plate 114 close to the battery pole piece 200 is connected to the baffle 116, and the baffle 116 protrudes upward from the bottom side plate 114. In this way, the baffle 116 can block dust and foreign matter entering the cover 110, and reduce the dust and foreign matter from falling from between the bottom side plate 114 and the battery pole piece 200 to the outside of the cover 110.

[0075] refer to Figure 3 In some embodiments, the upper end of the baffle 116 is inclined relative to the lower end toward the direction close to the battery electrode 200, so that the upper end of the baffle 116 is closer to the battery electrode 200, thereby better blocking the dust and foreign matter from entering the cover body 110, and more effectively reducing the dust and foreign matter from falling from between the bottom side plate 114 and the battery electrode 200 to the outside of the cover body 110.

[0076] refer to Figure 2 and Figure 3 In some embodiments, there are two groups of cleaning components 100, and the dust suction ports 101 of the covers 110 of the two groups of cleaning components 100 are arranged opposite to each other, and a gap for accommodating the battery electrode 200 is formed between the two groups of cleaning components 100. When the battery electrode 200 is located in the gap, the two groups of cleaning components can clean the two sides of the battery electrode 200 respectively.

[0077] In some embodiments, the battery electrode cleaning device further comprises an opening and closing mechanism, and the covers 110 of the two cleaning assemblies 100 are respectively connected to the opening and closing mechanism, so that the opening and closing mechanism can drive the covers 110 of the two cleaning assemblies 100 to move relatively closer or farther away.
