In a specific workflow: the tail end of the lithium battery pole piece on the unreeling mechanism 250 is pulled to be correspondingly connected to the material storage mechanism 240, and then is connected to the material pulling component 212 after passing through the material pushing component 211; in the cutting process, when the pushing component 211 pushes the lithium battery pole piece, the pulling component 212 pulls the tail end of the lithium battery pole piece to move, when the distance between the pulling component 212 and the pushing component 211 reaches a preset value, the pulling component 212 stops moving, at the moment, the lithium battery pole piece between the pulling component 212 and the pushing component 211 is straightened and tightened by the pulling component 212 and the pushing component 211, and the folds of the lithium battery pole piece are leveled, so that the sheet cutting machine 20 can be suitable for wide lithium battery pole pieces; in addition, as the lithium battery pole piece is simultaneously pulled by the pulling part 212 and pushed by the pushing part 211, the two ends of the lithium battery pole piece along the length direction are not easy to wrinkle, and the lithium battery pole piece is suitable for wide lithium battery pole pieces; when the lithium battery pole piece is located at the cutting position, the upper cutter 2211 moves downwards to cut the lithium battery pole piece, the pressing and propping module 222 synchronously presses and propps against two sides of the lithium battery pole piece along the width direction, the lithium battery pole piece is stretched and the pressing and propping module 222 can press and prop two sides of the lithium battery along the width direction when cutting, and at the cutting position, the positioning precision of the length direction and the width direction of the pole piece can be ensured, so that the lithium battery pole piece is suitable for a large-width lithium battery pole piece. After being cut off, the lithium battery pole pieces correspondingly fall on the placement platform 6, the material taking device adsorbs the lithium battery pole pieces through at least two groups of vacuum adsorption groups, and the lithium battery pole pieces are moved through the moving mechanism.
The foregoing is only a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any person skilled in the art will be able to make insubstantial modifications of the present invention within the scope of the present invention disclosed herein by this concept, which falls within the actions of infringing the protection scope of the present invention.
