[0032] Working principle of the invention: Figure 7 The middle section describes part of the processing flow of electrode roll material, which consists of unwinding the electrode roll material, cutting the electrode roll material with four laser cutting components, slitting the electrode roll material into a first part and a second part by a slitting component, and rewinding the first part and the second part of the roll material respectively.

[0033] like Figure 4 As shown, arrow Y points in the direction of electrode roll feeding, and arrow X points in the direction of laser beam output. Figure 3 In this process, the electrode roll is conveyed from top to bottom. After passing the first conveying roller 3 above the first cutting adsorption seat 16, the electrode roll passes through the area d1 between the first cutting adsorption seat 16 and the first cutting back cavity 17, then passes through the first conveying roller 3 on the left side of the first cutting guide cavity 7, the first conveying roller 3 below it, and finally passes through the area d2 between the second cutting adsorption seat 18 and the second cutting back cavity 19. In this embodiment, Figure 3The direction is used as a reference standard. For example, the left side of the first cutting adsorption seat 16 is the first cutting back cavity 17, and the lower side of the first cutting back cavity 17 is provided with the first conveying roller 3. The first cutting adsorption seat 16 is provided with a negative pressure space. The negative pressure adsorption of the first cutting adsorption seat 16 is achieved by connecting the negative pressure unit, so that the electrode roll material between the first cutting adsorption seat 16 and the first cutting back cavity 17 is conveyed to adhere to the surface of the first cutting adsorption seat 16. The top of the first cutting back cavity 17 is rounded at one end face near the first cutting adsorption seat 16 to facilitate the conveying of the electrode roll material and protect the electrode roll material, avoiding damage to the electrode roll material by sharp edges. In addition, one end of the L-shaped structure 33 can further limit the electrode roll material to prevent the electrode roll material from deviating. The laser beam output by the upper laser cutting unit 5 can pass horizontally through the first cutting back cavity 17 and the first cutting adsorption seat 16; the laser beam output by the lower laser cutting unit 6 can pass horizontally through the second cutting adsorption seat 18 and the second cutting back cavity 19 to achieve the cutting of the electrode roll material. Furthermore, the first cutting guide cavity 7 and the second cutting guide cavity 8 have the same structure, both including a negative pressure cavity and a belt unit 31, which can provide support and adsorption for the passing electrode roll, and can closely fit and transport the electrode roll to ensure stable transport and cutting of the electrode roll. However, the structural distribution positions of the first cutting guide cavity 7 and the second cutting guide cavity 8 are different. The first cutting guide cavity 7 is located below the first cutting adsorption seat 16 and extends downward, so that the first conveying roller 3 on the left and the L-shaped structure 33 limit the electrode roll. Correspondingly, on the left side, the second cutting guide cavity 8 is distributed and extends downward below the second cutting adsorption seat 18, so that the second conveying roller 4 and the L-shaped structure 33 on the right side define the position of the right side of the electrode roll. Therefore, the first cutting guide cavity 7 and the second cutting guide cavity 8 are obliquely opposite to each other, which makes the electrode roll conveyed from top to bottom more stable. The lower end of the electrode roll is the left adsorption support, and the upper end of the electrode roll is the right adsorption support. This structural distribution greatly improves the overall adsorption support effect.

[0034] In this embodiment, the unwinding assembly 1 is used to unwind the electrode roll, and a flattening roller assembly can also be set to flatten the wrinkled electrode roll upon arrival; the tension splicing assembly 14 may include a splicing mechanism for splicing the electrode roll when changing rolls, and a tension swing arm mechanism for adjusting the electrode roll left and right to the required tension to achieve constant tension closed-loop control of the strip; the reinforcing assembly presses textures onto the electrode roll through the reinforcing wheel 25 to enhance the vertical strength of the electrode roll, making it less likely for the electrode tabs to fold during subsequent belt feeding; the reinforcing lateral movement mechanism 23 can drive... The reinforcing wheel 25 moves horizontally to adjust its horizontal position. The reinforcing lifting mechanism 24 can be a pneumatic or electric cylinder. The reinforcing lifting mechanism 24 can cause the reinforcing wheel 25 to move up and down, thereby pressing the electrode coil wound on the processing roller 22. The deviation correction component can correct the deviation phenomenon of the electrode coil during the conveyor belt process (this is existing technology and will not be described in detail). The four laser cutting components can laser cut the electrode coil to form electrode ears and mark holes. The first dust removal mechanism 9 can be an air knife to perform front and back air knife treatment on the electrode coils on the upper and lower conveyor belts after laser cutting. For dust removal, the second dust removal mechanism 10 can be equipped with an air knife to remove dust from both sides of the first and second portions of the electrode roll after slitting. It can also be equipped with a strong magnetic strip to remove metal debris from the first and second portions of the roll. The detection mechanism 11 can include a CCD length measuring unit to measure the distance traveled by the electrode roll, a CCD electrode front and back defect detection unit for visual inspection of defects in the coating areas on both sides of the electrode roll, and a CCD electrode tab size detection unit for visual inspection of the quality of the formed electrode roll. In addition, a CCD... The CD defect marking component, based on the CCD detection results of the front detection mechanism 11, can label defective products through a labeling machine, and is equipped with a leak-proof label sensor, which will alarm and stop the machine if a label is missed. In addition, a pressing component can be set up to press the first and second parts of the roll during take-up and roll changing. The smoothing structure smooths the electrode roll side to prevent the electrode tabs from folding or bulging. The smoothing structure can be equipped with smoothing rollers to smooth the electrode roll. A take-up and push component can be set up to push out the fully taken-up first and second parts of the roll for easy manual unloading. In the slitting assembly, the upper slitting blade holder 29 is mounted in the middle of the upper slitting roller 27, and the lower slitting blade holder 30 is mounted in the middle of the lower slitting roller 28. In this embodiment, the cutter body 35 is mounted on the upper slitting blade holder 29. In another embodiment, the cutter body 35 can also be mounted on the lower slitting blade holder 30. The height of the cutter body 35 can be adjusted for both the upper slitting blade holder 29 and the lower slitting blade holder 30 to facilitate adjustment of the contact between the cutter body 35 and the electrode roll. Both the upper slitting roller 27 and the lower slitting roller 28 can be equipped with corresponding drive motors, which can respectively cause the upper slitting roller 27 and the lower slitting roller 28 to rotate.Both the first adjustment mechanism 20 and the second adjustment mechanism 21 can be selected from telescopic or moving mechanisms such as cylinders or electric cylinders. The third adjustment mechanism 34 can be selected from multiple sliding structures. The sliding structures adjust the displacement of the first cutting guide cavity 7 or the second cutting guide cavity 8 in the up-down, left-right, and front-back directions. In this embodiment, it includes a vertical guide rail, a vertical slider, a horizontal guide rail, a horizontal slider, a longitudinal guide rail, and a longitudinal slider.
