[0013] 2. The first cutting unit uses a cross-shaped adjustment slot and a movable seat. By adjusting the position of the movable seat and the number of the first laser cutting machine, it can flexibly realize the slitting of copper foils of different widths. The slitting quantity can be freely set according to production needs to adapt to diverse processing size requirements.

[0015] 3. After passing through the guide rollers, the copper foil can be wound around the first and second winding rods of the winding structure (arranged along the four corners of the square) to form a regular frame. The first and second cutting units then cut the foil, allowing the slices to be naturally stacked into a concave shape. The self-locking feature of the concave structure avoids the problems of slice misalignment and detachment in traditional stacking, reducing subsequent finishing steps and improving product consistency.

[0016] 4. The transposition structure can not only adjust the relative position of the winding structure and the cutting structure to ensure cutting accuracy, but also fit and clamp the winding structure when it rotates and cuts, ensuring the stability of the winding and cutting process. For concavely stacked copper foil, the transposition structure can automatically flatten its ends when the conveyor belt assembly is guiding it, realizing a seamless transition from "winding, cutting and stacking" to "flattening and conveying". The whole process is highly automated, reducing manual intervention and improving production efficiency.

[0017] 5. The equipment can flexibly switch processing modes (direct slitting or cutting and stacking after winding) according to demand, and the various structural parameters (such as slitting width, number of slices, and winding size) are easy to adjust. It can not only meet the needs of batch standardized production, but also adapt to the processing needs of small batches and multiple specifications, taking into account flexibility and efficiency.

When winding the copper foil, one end of the copper foil is pulled to the pressure rod 778 for clamping, and the copper foil is cut into corresponding sizes with the help of the main body of the first laser cutting machine 44.

[0033] More specifically, the distance adjustment unit 77 can be driven by a motor to achieve precise adjustment of the spacing between the winding rods, adapting to the processing of copper foil frames of different sizes. At the same time, with the help of the cooperation between the pressure rod 778 and the winding rod, the copper foil can be quickly fixed, ensuring the stability of the winding process and providing a regular basic framework for subsequent cutting and stacking.

[0034] Working principle: The device is placed stably on the base 1 and controlled by the controller 32. The unwound copper foil enters from the left end of the guide frame 31 and is located under the two guide rollers 37 in the guide structure 3. The guide rollers 37 press the copper foil down on the upper wall of the guide frame 31 to keep it horizontal. Copper foils of different thicknesses can be raised and adjusted on the limit rod 33 with the help of the limit seat 34, and the limit seat 34 applies downward force with the help of the spring 36 to keep the guide roller 37 pressed down; then, by starting the first motor 38, the two guide rollers 37 can be driven to rotate on the roller arm 35 through the linkage between the pulley 39 and the transmission belt 30, thereby assisting the rightward transportation of the copper foil.

[0035] The first processing method is as follows: The copper foil laid flat between the guide rollers 37 is cut into different widths by the first cutting unit 4, that is, the movable seat 42 on the first hanging arm 41 is adjusted to slide in the adjustment slot 8, and the movable seat 42 is fixed by fastening bolts to adjust the spacing of the first laser cutting machine 44; The copper foil moves horizontally to the right and is cut into widths by the first laser cutting machine 44; and the copper foil is transported from under the rightmost guide roller 37 to the second cutting unit 5; By controlling the extension of the hydraulic cylinder 52 on the second boom 51 in the second cutting unit 5, the second laser cutting machine 54 is driven to descend close to the slit copper foil, and the first electric slide rail 53 is activated to drive the second laser cutting machine 54 to move back and forth, and cooperate with the copper foil moving to the right to achieve multi-piece linked slicing. The sliced copper foil falls from the right end of the guide frame 31 to the conveyor belt assembly 2 for guidance as it moves.

[0036] The second processing method is as follows: The copper foil is conveyed horizontally to the right by the downward pressure of the guide roller 37. After the copper foil passes through the guide roller 37, it can be manually pulled between the pressure rod 778 and the second winding rod 776 in the winding structure 7. The pressure rod 778 is pressed against the second winding rod 776 by the electric push rod 777 to clamp and fix it. The second motor 74 on the base 71 is started, and the second gear 75 is engaged with the first gear 73 to drive the sleeve shaft 72 to rotate, thereby driving the distance adjustment unit 77 on the adjustment plate 76 to rotate; the copper foil is wound around the three first winding rods 775 and the second winding rod 776 to form a square frame; The copper foil is cut by the first cutting unit 4 to ensure that the winding structure 7 is wound to a corresponding length. At the same time, the cut end of the copper foil is blocked by the second bidirectional slide rail 62 in the transposition structure 6, which drives the pressing shaft 64. For example, the distance adjustment unit 77 rotates clockwise, and the copper foil enters from the upper left side of the distance adjustment unit 77. The end of the copper foil is located above the distance adjustment unit 77, and the pressing shaft 64 is moved close to the first winding rod 775 or the second winding rod 776 to block it. The end of the copper foil is bent and wound under the force, and the end of the copper foil is located in the middle of the outer wall after being wound into the frame. At this time, the first bidirectional slide rail 61 can be used to drive the winding structure 7 to move left and right, so that the wound copper foil is aligned with the second cutting unit 5. The second cutting unit 5 cuts the middle part of the upper and lower side walls of the frame copper foil in a reverse direction as the distance adjustment unit 77 rotates. Before cutting, the second electric slide rail 63 is controlled to adjust the spacing of the pressing shaft 64 according to the spacing of the first winding rods 775. When one side of the frame copper foil is cut, the other side is not cut, and the pressing shaft 64 is engaged with the first winding rod 775 to clamp the copper foil before cutting. At this time, the cut copper foil forms two concave shapes, and the copper foil is stacked after being wound. The copper foil is again controlled by the first bidirectional slide 61 to descend to the upper arm of the right end of the guide frame 31 for unloading. The unloading drive adjuster 77 rotates to make the two ends of the concave copper foil face upward. The copper foil can be pushed by the pressing shaft 64 through the lateral movement length of the second bidirectional slide 62, or the pressing shaft 64 is placed inside the concave copper foil and fits the two ends respectively, driving the copper foil to move to the conveyor belt assembly 2 for guidance. If the pressing shaft 64 is located in the concave copper foil, the pressing shaft 64 can be relatively separated and moved to bend the two ends of the copper foil flat and then guide it; The length of the copper foil stacked and cut by the winding structure 7 can be adjusted by starting the third motor 771 to drive the torque seat 772 to rotate, and the four pulling arms 773 are driven to rotate and move through the torque seat 772, so that the slider 774 can move in the slide 9, and the spacing between the first winding rod 775 and the second winding rod 776 can be adjusted synchronously, thereby changing the cutting length after winding.
