Description

Technical Field

[0001] The invention relates to the technical field of copper foil production and processing equipment, and in particular to a slitting device for lithium battery copper foil processing. Background Art

[0002] In lithium batteries, lithium battery copper foil is mainly used as the negative electrode current collector; it can collect and conduct the current generated by the negative electrode during the battery reaction; for example, in the process of lithium ion embedding and de-embedding, electrons need to be conducted to the external circuit through copper foil to realize the battery's charge and discharge function; copper foil is mostly made by electrolysis, with copper as the anode and titanium or stainless steel as the cathode, and is made by electrolysis in copper sulfate electrolyte. However, after the copper foil is produced, it will be cut into corresponding widths and rolled up according to subsequent needs during the transportation process, and then the copper coils of different widths will be packaged and supplied to the corresponding users; however, the existing copper foil slitting mechanism, the slitting tool needs to be replaced after wear, and the existing slitting equipment tool changing process is relatively complicated and takes a long time; this includes steps such as tool removal, installation, and debugging, especially some multiple tools installed on the same carrier according to different width requirements, this period The equipment is in a shutdown state during the period, which reduces the production efficiency; and although multiple cutters are installed on the same carrier to achieve adjustable cutting of different widths, the adjustment range is relatively reduced, and the cutters may even be idle and unable to achieve corresponding width adjustment. For example, three cutters are installed on a carrier, and four different widths of slitting can be achieved simultaneously through the three cutters. Generally, the cutters need to contact with the guide roller to apply pressure to cut, and then when three equal cuts are required, one cutter will be idle, and then it needs to be removed, which is more cumbersome, and the cutter itself has a certain thickness. If the cutting width is small, the relative fit of the two cutters cannot be achieved; at the same time, the equipment structure is complex and fixed, and it is impossible to adjust and change according to the needs.

The length of the horizontal frame can be spliced ​​and extended according to the needs, which improves the flexibility of the equipment. For example, when facing the production needs of copper foil of different scales, the scale of the equipment can be easily adjusted. For small-scale production tasks, a shorter horizontal frame can be used to reduce the space and cost of the equipment; and for large-scale production tasks, by splicing and extending the horizontal frame, the number of slitting, guiding and winding structures can be increased to meet the needs of large-scale production.

On the one hand, it can accurately meet the specific requirements of different customers for the cutting width of copper foil. For example, when copper foil of a specific width is required for the production of special types of lithium batteries, it can be achieved by adjusting the position and number of cutters; on the other hand, it can perform multi-level adjustment of the cutting width range to meet the production needs of copper foils of various widths. There is no need to equip different slitting equipment for each width, which reduces equipment costs.

[0015] 3. By adding multi-component cutting structure, guiding structure and winding structure, it can be used for cutting, guiding and winding of different widths at different levels. This enables the solution to achieve simultaneous production of copper foils of various specifications on the same equipment, thereby improving production efficiency and equipment utilization.

[0016] 4. The guide structure guides the copper foil and then it enters the winding structure to form differentiated winding, which helps to classify copper foils of different specifications or batches. In actual production, copper foils of different quality grades or different uses may need to be rolled separately. This solution can meet this demand well and facilitate subsequent quality inspection, packaging and delivery processes.

[0017] 5. The corresponding winding roller can be disassembled and assembled according to the corresponding winding requirements. This feature makes the equipment easier to operate when facing different winding tasks; for example, when it is necessary to replace winding rollers of different diameters or types to adapt to the winding of copper foil of different lengths or thicknesses, the disassembly and assembly operation can be carried out quickly, reducing the equipment adjustment time and improving production efficiency. Moreover, it is easy to disassemble and replace after winding, which is conducive to quickly switching different production tasks or maintaining and replacing the winding roller.

The cut copper foil is passed through the lower wall of the guide rod 54 in the guide structure 5, and the copper foil of the corresponding width is connected to the winding roller 78 in the winding structure 7 for winding. The copper foil of other widths passes through the upper wall of the cutting wheel 668 of the next processing mechanism, and is cut again, guided and wound by the cutter 665.
