The driving roller 130 and the driven roller 140 are arranged in parallel and are spaced apart, and are rotatably mounted on the rack 110. The driving roller 130 and the driven roller 140 can rotate relative to the rack 110, and the rack 110 can simultaneously limit the driving roller 130 and the driven roller 140. The first driving member 120 is mounted on the rack 110 and is in transmission connection with the driving roller 130. The driving roller 130 is connected with the driven roller 140 through the transmission belt 150. The first driving member 120 is used to drive the driving roller 130 to rotate, so as to drive the driven roller 140 to rotate through the transmission belt 150. The transmission belt 150 is used to carry the electrode sheet 800. The rack 110, the transmission belt 150, the driving roller 130, and the driven roller 140 together form an adsorption cavity 180. The transmission belt 150 is densely provided with a plurality of through holes 151, which are in communication with the adsorption cavity 180. The vacuum pumping assembly 160 is in communication with the adsorption cavity 180. The vacuum pumping assembly 160 is used to suck the external air into the adsorption cavity 180 through the through holes 151, and then suck the air in the adsorption cavity 180 away, so as to form a negative pressure and adsorb the electrode sheet 800 on the transmission belt 150, thereby fixing the relative position of the electrode sheet 800 and the transmission belt 150. The transmission belt 150 is used to drive the electrode sheet 800 to move under the action of the driving roller 130. In this process, since the electrode sheet 800 is stably adsorbed on the transmission belt 150 under the action of the negative pressure, the electrode sheet 800 will not shift or deviate relative to the transmission belt 150, so as to realize precise feeding of the electrode sheet 800. The first dust removal assembly 170 is mounted on the rack 110. In the process of the transmission belt 150 driving the electrode sheet 800 to feed forward, the first dust removal assembly 170 is used to remove dust from the side of the electrode sheet 800 away from the transmission belt 150, so as to remove foreign matter on the surface of the electrode sheet 800, and realize cleaning and dust removal of the electrode sheet 800. In this way, the feeding and dust removal mechanism 100 can simultaneously realize cleaning and dust removal and precise feeding of the electrode sheet 800, effectively remove foreign matter on the surface of the electrode sheet 800, reduce the short circuit rate of the battery cell, improve safety, and ensure accurate feeding position and improve the yield of the battery cell.

The brush roller 172 is rotatably installed on the mounting frame 171, and the brush roller 172 can rotate relative to the mounting frame 171 to clean the pole piece 800 sent forward under the action of the transmission belt 150, and the mounting frame 171 can limit the brush roller 172.

[0037] Preferably, the first dust removal assembly 170 further comprises a second driving member 173. The second driving member 173 is installed on the mounting frame 171 and is in transmission connection with the brush roller 172. The second driving member 173 is used to drive the brush roller 172 to rotate, so as to improve the cleaning efficiency and enhance the cleaning effect. Specifically, the rotating direction of the brush roller 172 is opposite to the feeding direction of the pole piece 800, so as to further improve the cleaning effect.

[0038] Preferably, the first dust removal assembly 170 further comprises a dust suction box 174 and a dust suction pump (not shown in the figure). The dust suction box 174 is installed on the mounting frame 171 and is connected with the dust suction pump. The dust suction box 174 is provided with a dust suction port (not shown in the figure) near one side of the transmission belt 150. The dust suction pump is used to generate negative pressure, so as to suck the foreign matters on the pole piece 800 into the dust suction box 174 through the dust suction port, thereby realizing the dust suction function and preventing the foreign matters from flying around under the cleaning action of the brush roller 172, so as to protect the on-site working environment.

[0039] Further, the number of the dust suction boxes 174 is two. The two dust suction boxes 174 are oppositely arranged on both sides of the brush roller 172, and the two dust suction boxes 174 are connected with the dust suction pump. The dust suction pump can simultaneously generate negative pressure on the two dust suction boxes 174, so as to improve the dust suction effect and further prevent the foreign matters from flying around. Specifically, the length direction of the dust suction box 174 is the same as the axial direction of the brush roller 172, and the length of the dust suction box 174 is greater than the axial length of the brush roller 172, so as to realize the comprehensive coverage of the dust suction box 174 on the cleaning area of the brush roller 172, ensure that the foreign matters cleaned from the pole piece 800 can be completely sucked into the dust suction box 174, and further improve the dust suction effect.

[0040] The vacuumizing assembly 160 comprises a negative pressure pipe 161 and a vacuum pump (not shown in the figure). The negative pressure pipe 161 is installed on the rack 110. One end of the negative pressure pipe 161 is in communication with the adsorption cavity 180, and the other end is in communication with the vacuum pump. The vacuum pump can suck out the air in the adsorption cavity 180 through the negative pressure pipe 161, so as to realize the vacuumizing function, and thereby vacuum-adsorb the pole piece 800 on the transmission belt 150 through the plurality of through holes 151.

The filter screen is installed in the negative pressure pipe 161, and the vacuum pump is used to suck off the foreign matters on the side of the pole piece 800 close to the transmission belt 150, and the filter screen is used to collect the foreign matters to achieve the dust removal function and further improve the dust removal effect.

[0042] It should be noted that the foreign matters will be attached to both sides of the pole piece 800 after the cutting. Due to the structural limitation of the cutting mechanism 700, the foreign matters attached to the first side of the pole piece 800 are much more than those attached to the second side of the pole piece 800. In the embodiment, the second side of the pole piece 800 is attached to the transmission belt 150, so that the first side of the pole piece 800 is close to the first dust removal assembly 170. During the feeding process, the more foreign matters on the first side of the pole piece 800 will be completely removed under the action of the first dust removal assembly 170, and the less foreign matters on the second side of the pole piece 800 will enter the suction cavity 180 through the through hole 151 under the suction action of the vacuum pump, and then enter the negative pressure pipe 161 and be filtered by the filter screen.

[0043] Preferably, the feeding and dust removal mechanism 100 further comprises a compression roller assembly 190. The compression roller assembly 190 comprises a third driving member 191, an adjusting frame 192 and a compression roller 193.

The pole piece 800 can be conveyed from between the compression roller 193 and the driven roller 140 to the transmission belt 150. The transmission belt 150 is used to feed the pole piece 800 from the driven roller 140 to the direction of the driving roller 130. Specifically, the third driving member 191 is used to drive the compression roller 193 to approach or move away from the driven roller 140 through the adjusting frame 192 to adjust the pressure of the compression roller 193 on the pole piece 800, so as to ensure that the pole piece 800 keeps close contact with the transmission belt 150 during the conveying process to the transmission belt 150, thereby ensuring the vacuum suction effect and improving the feeding precision.
