[0017] A method for using a lithium battery electrode multiple slitting machine specifically comprises the following steps:

[0018] S1. Preparation stage:

[0019] S11. Ensure that all parts are installed correctly, and the air shaft, winding shaft, fixing plate, first cutter, pressing plate, second cutter, etc. are in good working condition;

[0020] S12, adjusting the number of the first cutters as needed, unscrewing the fixing screws, moving the mounting plate horizontally, adjusting the position and angle of the rectangular plate, and finally re-fixing it;

[0021] S2. Place the battery pole piece:

[0022] S21, moving the baffle plate vertically upward so that the baffle plate no longer blocks one end of the inflatable shaft;

[0023] S22, placing the battery pole piece on the air shaft at the feeding end, ensuring that the battery pole piece is flat and in the correct position;

[0024] S3, feeding and adjusting path:

[0025] S31, start the feeding mechanism, and feed the battery pole piece through the air shaft;

[0026] S32, using multiple winding shafts to adjust the path of the battery electrode sheet to ensure that the battery electrode sheet can be laid flat on the fixed plate;

[0027] S4, cutting and winding:

[0028] S41, when the battery electrode is laid flat on the fixed plate, start the drive motor;

[0029] S42, the output shaft of the driving motor drives the rotating rod to rotate, and then drives the air shaft to rotate, and the winding process begins;

[0030] S43, during the winding process, the rotation of the turntable and the convex plate will move the connecting horizontal plate and the connecting vertical plate downward, thereby driving the rectangular plate, the first cutting knife and the pressing plate downward;

[0031] S44, the first cutter cuts the battery electrode piece, and the pressing plate presses the battery electrode piece to ensure the cutting effect;

[0032] S45, the second cutter cuts the cut position again during the movement of the battery electrode sheet to ensure the cutting effect;

[0033] S5. Take out the battery pole piece:

[0034] S51, when the battery electrode sheet is rolled up, the driving motor is stopped;

[0035] S52, moving the baffle plate vertically upward so that the baffle plate no longer blocks one end of the air shaft at the winding end;

[0036] S53, taking out the cut battery pole piece from the air shaft at the winding end.

[0037] In the present application, when in use, the battery electrode sheet is fed through an air shaft, the path is adjusted through multiple winding shafts, and after being laid flat on a fixed plate, it is cut and then rolled up through another air shaft. When rolling up and placing the battery electrode sheet, the baffle can be moved vertically upward, and the baffle no longer blocks one end of the air shaft, which can facilitate the placement and removal of the battery electrode sheet;

[0038] When winding, the driving motor is started, and the output shaft of the driving motor drives the rotating rod to rotate, and the rotating rod drives the air shaft to rotate, thereby completing the winding process of the battery electrode. At the same time, during the winding process, the rotating rod drives the rotating disk to rotate, and the rotating disk drives the convex plate to rotate, and the convex plate continuously drives the connecting horizontal plate to move downward, and the connecting horizontal plate drives the connecting vertical plate to move downward;

[0039] At this time, the connecting vertical plate can drive one of the sliders to move downward, and the slider drives the connecting rod to move downward and squeeze the spring. At this time, the connecting rod drives multiple external rectangular plates to descend, and the rectangular plates drive the corresponding first cutters and pressing plates to descend. The first cutter cuts the corresponding position of the battery pole piece, and the pressing plate can press the battery pole piece at intervals to ensure the cutting effect of the battery pole piece;

[0040] At the same time, when the first cutter cuts the battery electrode sheet, the second cutter is always located on one side of the battery electrode sheet, and the second cutter is arranged between the multiple battery electrode sheets after cutting. As the battery electrode sheet continues to move, the second cutter will cut the position after cutting again to ensure the cutting effect;

[0041] And the number of the first cutters can be adjusted according to needs. The specific operation is to unscrew the two fixing screws, then the braking state of the mounting plate can be released, and the mounting plate can be moved laterally. The mounting plate can drive multiple sliding plates to move laterally through the insertion rod. At this time, the multiple sliding plates can drive the two positioning blocks to move out from the inside of the positioning groove, and the braking state of the rectangular plate can be released. At this time, the corresponding rectangular plate can be rotated to make the insertion rod move inside the arc hole, and then the rectangular plate can be flipped 180 degrees, and the number of the first cutters can be adjusted to facilitate application in various situations.

[0042] Beneficial effects: Improved operational convenience: By moving the baffle vertically upward, the battery pole piece can be conveniently placed and removed without complicated operating steps, thereby improving work efficiency.

[0043] Ensure cutting effect: Through the coordinated use of the first cutter and the second cutter, the battery pole piece can be accurately cut, the cutting is neat and without damage, and the quality and performance of the battery are guaranteed.

[0044] Enhanced adjustment flexibility: The number and position of the first cutter can be adjusted according to actual needs, which is suitable for processing battery poles of various specifications and types, improving the versatility and flexibility of the equipment.

[0045] Optimized structural design: Through the design of transmission mechanisms such as rotating rods, rotating disks, and convex plates, the automatic descent and reset of the cutting mechanism are realized, which reduces manual operations and improves the automation level of the equipment.

[0046] Improve production efficiency: The entire processing process is highly automated and easy to operate, which can greatly improve the processing efficiency of battery electrodes and reduce production costs. BRIEF DESCRIPTION OF THE DRAWINGS

Take out the battery pole piece: S51, when the battery electrode sheet is rolled up, the driving motor (17) is stopped; S52, moving the baffle plate (3) vertically upward so that the baffle plate (3) no longer blocks one end of the air shaft (5) at the winding end; S53, taking out the cut battery pole pieces from the air shaft (5) at the winding end.
