The present embodiment provides a tab cutting device including a first conveying roller 10, a second conveying roller 11, a separating assembly, a suction cup plate 30, a dust removing assembly, a laser 20, and a negative pressure belt 50.
The first conveying roller 10 and the second conveying pipe are disposed in parallel in a preset direction, thereby being used for conveying the pole piece in the preset direction. A laser 20 is positioned between the first conveyor roller 10 and the second conveyor roller 11 for cutting the pole piece. The negative pressure belt 50 is located downstream of the laser 20 in a preset direction, the negative pressure belt 50 group has a first negative pressure surface 51 and a second negative pressure surface 52 which are sequentially arranged in the preset direction, the first negative pressure surface 51 is located between the first conveying roller 10 and the second conveying roller 11 and is parallel to the preset direction so as to adsorb and tension the pole piece, and the second negative pressure surface 52 corresponds to the second conveying roller 11 and forms an included angle with the preset direction so as to adsorb and cut the waste.
From this, adsorb the tensioning pole piece through the first negative pressure face 51 with negative pressure belt 50 to the laser 20 cuts the pole piece, guarantees the stability of cutting, makes the cutting effect better. After the cutting is completed, the second negative pressure surface 52 of the negative pressure belt 50 is arranged at an included angle with the preset direction, so that the cutting waste can be adsorbed by the adsorption force of the second negative pressure surface 52, so that the cutting waste is separated from the stage, and the cutting waste is stably discharged under the adsorption and conveying of the second negative pressure surface 52, therefore, compared with the prior art, the pole ear finished product is not easy to mix with the cutting waste, and the product yield is improved.
It should be noted that, the first conveying roller 10 and the second conveying roller 11 are rotatably disposed on a frame, and are driven by a driving component such as a motor to perform an area, so as to rotate synchronously, and the pole piece is wound on the first conveying roller 10 and the second conveying roller 11, and the first conveying roller 10 and the second conveying roller 11 both drive the pole piece to convey along a preset direction through friction force.
The sucking disc board 30 is arranged between the first conveying roller 10 and the second conveying roller 11 and is located at the upstream of the laser 20 in the preset direction and used for sucking and tensioning the pole piece, a cutting cavity 40 is formed between the sucking disc board 30 and the negative pressure belt 50, the laser 20 is arranged corresponding to the cutting cavity 40, and therefore the pole piece is sucked and tensioned through the sucking disc board 30 and the first negative pressure surface 51 of the negative pressure belt 50 together, so that the pole piece is straightened, and the laser 20 is more stable in cutting. Wherein, sucking disc board 30 and negative pressure belt 50 are located the same side of pole piece, and sucking disc board 30 adsorb face and first negative pressure face 51 coplane to better make the pole piece straighten.

The dust removal air knife is located on one side of the pole piece, close to the laser 20, so that dust generated during cutting is blown to one side of the pole piece, which is opposite to the laser 20, so that the laser beam emitted by the laser 20 is prevented from being interfered by the dust, and cutting stability is guaranteed.
The two dust removing air knives can be specifically divided into a first dust removing air knife and a second dust removing air knife, and the first dust removing air knife and the second dust removing air knife are respectively positioned on the upper side and the lower side of the laser beam so as to blow air to the cutting position on the pole piece.
In addition, an anti-turnover air knife is additionally arranged on the side edge of the negative pressure belt 50, so that the phenomenon that the tab is pressed and turned by the waste material when the waste material and the tab are separated is avoided.
It should be noted that, in the use process of the tab cutting device of this embodiment, the speed of the negative pressure belt 50 may be set to be greater than the conveying speeds of the first conveying roller 10 and the second conveying roller 11. The advantage of setting up like this is that can form the speed difference between negative pressure belt 50 and the pole piece, and in this case, the pole piece can receive great tension and be in the tensioning state all the time owing to the attraction of negative pressure belt 50, and consequently, the pole piece is difficult to appear the accumulation material phenomenon, and laser 20 cuts also more stably, can further ensure the shaping quality of utmost point ear from this.
The negative pressure belt 50 is provided with a plurality of negative pressure holes which are arranged in a staggered manner so as to be beneficial to the stable adhesion of the waste materials to the belt, ensure the separation of the waste materials and the lugs, and ensure that the pole pieces can be stably conveyed. In addition, the negative pressure belt 50 is designed with a continuous negative pressure groove to prevent negative pressure leakage to the maximum extent, and when the height, width and waste edge width of the tab change, the hole of the negative pressure belt 50 still can well adsorb the tab and the waste edge.
