Referring to fig. 1 and fig. 2, in the present embodiment, a dust removing device 29 is provided for removing dust from a battery pole piece, and includes:

the adsorption mechanism 1 is used for generating suction force so as to adsorb the battery pole piece;

the blowing mechanism 2 is used for generating flowing air flow on the surface of the battery pole piece and generating negative pressure on the surface of the battery pole piece through the Bernoulli effect so as to separate the dust attached to the surface of the battery pole piece from the battery pole piece;

and the air suction mechanism 3 is used for sucking the separated dust.

In the battery production process, sometimes, the designated position on the battery pole piece needs to be cleaned by laser. Under the effect of laser, the coating on battery pole piece surface can absorb certain energy, and at this moment, in the position of being shone by the laser, the coating can take place gasification, sublimation and vibration etc. until disappearing, along with getting rid of this part coating, corresponding pattern can appear on battery pole piece's surface, just reaches laser cleaning's purpose from this to conveniently carry out the utmost point ear welding of next preface.

During the laser cleaning process, the removed coating is converted into dust, and when the dust is attached to the battery pole piece, the dust can affect the pole lug welding of the subsequent process. If the dust attached to the surface of the battery pole piece is not removed, the dust attached to the battery pole piece can contaminate the welding head during the welding process of the pole tab, thereby affecting the welding tension between the battery pole piece and the pole tab and the effective welding area.

In this embodiment, the dust attached to the battery pole piece can be removed by the dust removing device 29, so that the above-mentioned problem can be avoided.

Under the mutual cooperation of the adsorption mechanism 1, the blowing mechanism 2 and the suction mechanism 3, dust attached to the battery pole piece is removed, wherein the adsorption mechanism 1 adsorbs the battery pole piece, so that the position of the battery pole piece is fixed; under the action of the blowing mechanism 2, high-speed airflow is generated on the surface of the battery pole piece, negative pressure is generated on the surface of the battery pole piece through the Bernoulli effect, and dust attached to the surface of the battery pole piece under the action of the negative pressure is separated; the separated dust is sucked away by the suction mechanism 3.

The battery pole piece is in contact with the roller 5, and the roller 5 can be used for guiding the battery pole piece, so that the battery pole piece can move according to a set track and direction.

The movement path of the battery pole pieces can be changed by the roller 5, and therefore, the laser cleaning interval and the dust removing range of the dust removing device 29 are limited. Herein, the region of the battery plate to be subjected to laser cleaning and the range of dust removal are limited between the two rollers 5.

After the suction plate 6 adsorbs the battery pole piece, laser cleaning can be carried out on the adsorbed position on the battery pole piece by using laser. In the process of laser cleaning, the position irradiated by the laser on the battery pole piece generates heat because the energy of the laser is absorbed. In order to avoid the deformation of the battery pole piece caused by heat generation, the battery pole piece needs to be cooled.

In order to avoid the above situation, the adsorption mechanism 1 may be provided with a driving member for driving the adsorption mechanism 1 to approach or depart from the battery pole piece.

The air consumption of the air supply device can be reduced by using the Bernoulli effect, and meanwhile, the noise generated when the air flow flows can be reduced.
