[0025] Embodiment 1

[0026] This embodiment provides a dust removal and adsorption structure, which is used for dust removal and adsorption of pole pieces.

[0027] See also Figure 1 and 2 The dust removal adsorption structure includes an adsorption member 1, and the adsorption member 1 has an adsorption port 11 and a dust removal port 12. The adsorption port 11 is arranged at the bottom of the adsorption member 1, and the adsorption port 11 is connected to the air inlet of the negative pressure device; the dust removal port 12 is arranged at the side of the adsorption member 1, and the dust removal port 12 is connected to the air outlet of the positive pressure device, and the dust removal port 12 is arranged at an angle. The dust removal port 12 of this embodiment is arranged at an angle, so that the airflow output by the dust removal port 12 can be blown onto the adsorbed surface, thereby achieving dust removal.

[0028] In specific application: the adsorbent 1 is driven by a driving mechanism to approach the pole piece. In the process of approaching the pole piece, the airflow output by the positive pressure device is blown out through the dust removal port 12. The airflow blows onto the surface of the pole piece and takes away the dust on its surface. When the adsorbent 1 contacts the pole piece, the negative pressure formed by the adsorption port 11 is used to adsorb the pole piece.

[0029] In this embodiment, the suction port 11 includes a plurality of suction ports 11, and the suction ports 11 are distributed in a rectangular array, and the suction holes 111 are connected to the air inlet of the negative pressure device through a negative pressure channel. The suction holes 111 are cylindrical, which is easy to process.

[0030] In this embodiment, the dust removal port 12 includes a plurality of dust removal holes 121, and the dust removal holes 121 are distributed along the side of the adsorbent 1, and the dust removal holes 121 are connected to the air outlet of the positive pressure device through the positive pressure channel. Figure 3 The dust removal hole 121 is cylindrical and inclined, and the angle α between the central axis of the dust removal hole 121 and the horizontal line is 30-60°, and the preferred value is 45°. The dust removal holes 121 of this embodiment are distributed on the four sides of the adsorbent 1, so that the airflow is blown out from the four sides of the adsorbent 1 and acts on the surface of the pole piece, ensuring the dust removal effect, and also preventing the pole piece from moving with the airflow.

[0031] To summarize, the dust removal and adsorption structure adds a dust removal port on the side of the adsorption component, and the airflow generated by the positive pressure device is output through the dust removal port. Because the dust removal port is inclined, the airflow output from the dust removal port can be blown onto the adsorbed surface, and the dust on the surface is taken away by the airflow to achieve contactless dust removal, so it will not damage the electrode and will not affect the battery performance.
