Then the existing dust collection device has poor adsorption effect, and can not effectively eliminate residual dust particles on the pole piece, thereby seriously affecting the production quality and efficiency of the pole piece.
Based on the above problems, referring to fig. 1, the present utility model provides a pole piece cutting device 10, which is applied to a pole piece 20 cutting process when manufacturing a lithium battery. The pole piece cutting device 10 comprises a blowing and sucking dust collection box 100, a movable cutting piece 200 and a fixed cutting piece 300 which are sequentially arranged.
In this embodiment, the pole piece 20 is typically moved along the fixed cutting member 300, the movable cutting member 200 and the blowing-sucking dust collection box 100 in sequence, so that after cutting by the fixed cutting member 300 and the movable cutting member 200, dust is blown and sucked by the blowing-sucking dust collection box 100, thereby ensuring that the cut pole piece 20 is clean.
Thus, it can be appreciated that the horizontal direction from right to left in fig. 1 is the direction of movement of the pole piece 20.
Further, the suction box 100 is provided with a passage 110, a first suction hole 120, a second suction hole 130, and a blowing hole 140. The first air suction hole 120 and the air blowing hole 140 are both communicated with the channel 110, the channel 110 is used for the pole piece 20 to pass through, the second air suction hole 130 is located at one side of the air blowing hole 140 away from the first air suction hole 120, the air blowing hole 140 is used for blowing the pole piece 20, the first air suction hole 120 is used for adsorbing blown dust, and the second air suction hole 130 is used for adsorbing dust generated by cutting.
In this embodiment, the pole piece 20 moves along a preset horizontal direction after cutting, and sequentially passes through the second air suction hole 130, the air blowing hole 140 and the first air suction hole 120, and the second air blowing hole 140 is located at a side facing the cutting member, so that dust particles generated in the cutting process can be immediately adsorbed by the second air suction hole 130 after the pole piece 20 is cut, and dust falling on the pole piece 20 is reduced; and to the dust that has adhered on pole piece 20, sweep through gas vent 140 to make the dust that adheres on pole piece 20 drop from pole piece 20, the dust that the rethread first suction port 120 absorption took off avoids the dust secondary adhesion, thereby has reached showing and effectively dedusting effect, guarantees that pole piece 20 clean up after the cutting, and then ensures the cutting quality of pole piece 20.
Further, the first suction hole 120 and the blowing hole 140 are disposed at an angle.
In this embodiment, the orientation of the first suction hole 120 and the air blowing hole 140 is an obtuse angle, so the suction-blowing type dust collection box 100 adopts a combined structure of suction and blowing, so that the dust collection effect is better.
Further, the direction of the first suction holes 120 is perpendicular to the extending direction of the channel 110, so that the first suction holes 120 can adsorb dust at various angles to the greatest extent, and the adsorption efficiency is improved.
In addition, the air blowing holes 140 are obliquely disposed in a direction toward the first air suction holes 120 such that the air flow blown out from the air blowing holes 140 moves toward the first air suction holes 120, so that dust moves to the first air suction holes 120 more easily following the air flow, thus improving the dust removing effect.
