It should be noted that the pole piece conveying mechanism 20 of the pole piece laser cleaning device 100 includes a first conveying roller 21 and a second conveying roller 22 which are vertically arranged, the cleaned pole piece 900 winds around the first conveying roller 21 and the second conveying roller 22, and the cleaned pole piece 900 is conveyed vertically upwards through the first dust removal opening 1511. In addition, the conveying mechanism can further comprise a negative pressure adsorption part 23, the negative pressure adsorption part 23 is provided with an adsorption surface 231, the adsorption surface 231 corresponds to the first dust removal port 1511 and is used for adsorbing and fixing the position of the part, corresponding to the first dust removal port 1511, of the cleaned pole piece, and therefore the situation that the cleaned pole piece 900 shakes and goes out of focus in the laser cleaning process is avoided. The laser mechanism 30 is disposed near the dust removing channel 15 and can emit a laser beam 31 to the first dust removing space 151 to clean the portion of the cleaned pole piece 900 corresponding to the first dust removing opening 1511.
Further, the pole piece laser cleaning dust removal mechanism 10 may further include a first dust hood 16, the first dust hood 16 is vertically disposed in the flow guiding space 150, and is disposed near one side of the cleaned pole piece 900, and vertically extends upward out of the flow guiding space 150, and the first dust hood 16 and the vertical cleaned pole piece 900 can together form a vertical second air inlet flow 162 channel, so that external air enters the first dust removal space 151 through the second air inlet flow 162 channel, in other words, the second air inlet flow 162 channel extends upward along the upper side of the first dust removal port 1511, and extends out of the flow guiding space 150, so that in the process of upward conveying of the cleaned pole piece 900, impurities such as dust attached to the cleaned pole piece 900 are adsorbed, and dust overflow is reduced.
In addition, the aperture of the second air inlet flow channel 162 is larger than the aperture of any one of the first air inlet flow channels 111, in other words, the flow rate of the gas entering the first dust removing space 151 through the second air inlet flow channel 162 is larger, so that the impurities such as dust generated at the first dust removing port 1511 are taken away in time by the gas with the larger flow rate, and the influence of the impurities such as dust on the laser beam 31 is further reduced.
Further, the laser cleaning and dust removing mechanism 10 for pole pieces may further include a second dust removing cover 17, a second dust removing port 1512 is further disposed on a side surface of the dust removing channel 15, and the second dust removing port 1512 corresponds to the first dust removing space 151 and is disposed opposite to the first dust removing port 1511, as shown in the figure. The second dust hood 17 is connected to the outer edge of the first dust removal port 1511, and extends to the first dust removal port 1511 in a direction opposite to the direction, a third air inlet channel 173 is arranged in the second dust hood 17, the third air inlet channel 173 can allow external air to enter the first dust removal space 151, and is used for allowing the laser beam 31 to enter, so that the laser beam 31 can sequentially irradiate the cleaned pole piece 900 through the third air inlet channel 173, the second dust removal port 1512, the first dust removal space 151 and the first dust removal port 1511, thus, when the cleaned pole piece 900 is cleaned by laser, the third air inlet channel 173 also has air to flow into the first dust removal space 151, and meanwhile, by arranging the second dust hood 17, the probability of dust overflowing through the second dust removal port 1512 is reduced.
Moreover, the second dust hood 17 extends back to the first dust removal port 1511, so that a certain distance is formed between the tail end of the second dust hood 17 and the first dust removal port 1511, thereby reducing the influence of the tail end of the second dust hood 17 on the negative pressure in the first dust removal space 151 and maintaining the wind speed of the first dust removal port 1511; the tail end of the second dust hood 17 and the first dust removal port 1511 which are far away from each other can also reduce the probability of dust overflow, and further reduce the interference of dust on light beams. In addition, the bottom surface of the second dust hood 17 is an inclined surface and is disposed to be inclined to the first dust removing space 151, so that the dust can be sucked away when falling on the inclined surface of the second dust hood 17, and the probability of dust overflow is further reduced.
Further, the bottom surface of the first baffle 11 is smoothly connected to the top surface of the third air inlet channel 173, as shown in fig. 4, so that the first dust removing space 151 is filled with the air flowing into the first air inlet space through the third air inlet channel 173, the first air inlet channel 111 and the second air inlet channel 162, thereby preventing the generation of dead space in the first dust removing space 151 and further reducing the turbulent flow.

In this embodiment, the first induced air surface 1211 partially extends out of the first dust removal port 1511, so as to further reduce the probability that impurities generated by laser cleaning fall through the gap between the second dust removal port 1512 and the pole piece 900 to be cleaned.
Further, the second flow guiding element 12 further includes a plurality of second gap bars 122, the second gap bars 122 are arranged at intervals along the bottom surface of the first dust removing space 151, and are located on one side of the first gap bars 121 away from the first dust removing port 1511, so as to be used for guiding the gas to uniformly flow downwards together with the first gap bars 121, in other words, the second gap bars 122 together form a plurality of bar holes, so that the negative pressure at different positions of the bottom surface of the first dust removing space 151 is uniform, the gas flows downwards uniformly, the downward stability of the gas flow is improved, and the occurrence probability of dead zones is further reduced.
The top surface of the second gap bar 122 is a second air inducing surface 1222, the second air inducing surface 1222 is disposed obliquely and is disposed to be biased to a side of the first dust removing space 151 opposite to the first dust removing port 1511, that is, to be biased to the second dust removing port 1512, so as to guide the air flow to bias the second dust removing port 1512 to flow, so that impurities such as dust generated by laser cleaning are discharged downwards more uniformly, and the air flow entering through the second air inlet flow channel 162 can be guided, so as to improve the uniformity of the downward flow of the air flow.
And the included angle between the first induced air surface 1211 and the vertical surface is larger than the included angle between the second induced air surface 1222 and the vertical surface of the first induced air surface 1211, so that the force for guiding the airflow to deviate to the second dust removing port 1512 is increased at a position close to the first dust removing port 1511, and the airflow is guided to deviate to the second dust removing port 1512 at a position far away from the first dust removing port 1511 with a lower force, so that the dust flows downwards more uniformly.
