Description

Technical Field

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

[0002] In a lithium battery, the lithium battery copper foil mainly serves as a negative electrode current collector; it can collect and conduct the current generated at the negative electrode during the battery reaction process; for example, during the process of lithium ion insertion and extraction, electrons need to be conducted through the copper foil to the external circuit to achieve the charge and discharge function of the battery; the copper foil is mostly processed by electrolysis method, with copper as the anode and titanium plate or stainless steel plate as the cathode, and is obtained through an electrolysis reaction in a copper sulfate electrolyte solution. However, after the copper foil is produced, it will be slit into corresponding widths according to subsequent requirements during transportation and then wound up, and then copper coils of different widths are packaged and supplied to corresponding users; however, for the existing copper foil slitting mechanism, the slitting tool needs to be replaced after wear, and the tool changing process of the existing slitting equipment is relatively complex and takes a long time; this includes steps such as tool disassembly, installation, and debugging. Especially for multiple tools installed on the same carrier according to different width requirements, the equipment is in a shutdown state during this period, reducing production efficiency; moreover, although installing multiple tools on the same carrier realizes the adjustment and cutting of different widths, it also relatively reduces the adjustment range, and there may even be a state where the tool is idle and the corresponding width adjustment cannot be achieved. For example: three tools are installed on one carrier, and four different widths can be slit simultaneously through the three tools. Generally, the tool needs to contact the guide roller to apply pressure to slit. Then, when three equal-width slitting is required, one tool will be idle and needs to be removed, which is rather cumbersome. Also, the tool itself has a certain thickness. If the cutting width is small, the two tools cannot be brought into contact with each other to achieve the slitting. At the same time, the equipment structure is complex and fixed, and cannot be adjusted and transformed according to requirements. After long-term use, the residual chips of the copper foil and equipment maintenance are also relatively inconvenient. Therefore, a slitting device for lithium battery copper foil processing is designed. Summary of the Invention

[0013] A slitting device for lithium copper foil processing proposed by the present invention has the beneficial effects that: by arranging a cross-frame main body to install a slitting structure, a guiding structure and a winding structure to form a combined cooperation, the process flow of cutting, guiding and winding the copper foil after production or during transportation is carried out; the length of the cross-frame can be spliced and extended according to requirements, and then multiple sets of slitting structures, guiding structures and winding structures are added, which are respectively used for cutting, guiding and winding of different widths at different levels; the slitting structure can set the position and number of cutting knives according to requirements for the adjustment of the cutting width and the multi-level adjustment of the cutting width range, and the copper foil is guided through the guiding structure and then enters the winding structure to form a differentiated winding; the corresponding winding roller is disassembled and assembled according to the corresponding winding requirements, and it is also convenient to disassemble and replace after winding; in summary, the present invention has the following effects:

[0014] 1. The length of the cross-frame can be spliced and extended according to requirements, improving the flexibility of the equipment. For example, in the face of copper foil production requirements of different scales, the scale of the equipment can be easily adjusted. For small production tasks, a shorter cross-frame can be used to reduce the equipment occupation space and cost; while for large production tasks, by splicing and extending the cross-frame, the number of sets of slitting, guiding and winding structures can be increased to meet the needs of large-scale production.

[0015] 2. The slitting structure can set the position and quantity of the cutting knives according to requirements, which provides great convenience for adjusting the cutting width. 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 needed for the production of special models of lithium batteries, it can be achieved by adjusting the position and quantity of the cutting knives. On the other hand, it can perform multi-level adjustment of the cutting width range to adapt to the production requirements of copper foils of various widths, eliminating the need to equip different slitting devices for each width, thus reducing equipment costs.

[0016] 3. By adding multiple sets of slitting structures, guiding structures, and winding structures, it can be used for cutting, guiding, and winding of different widths at different levels. This enables the scheme to simultaneously produce copper foils of multiple specifications on the same equipment, improving production efficiency and equipment utilization rate.

[0017] 4. After the guiding structure guides the copper foil and enters the winding structure for differential winding, this helps to classify and process copper foils of different specifications or batches. In actual production, copper foils of different quality grades or different uses may need to be wound separately, and this scheme can well meet this requirement, facilitating subsequent processes such as quality inspection, packaging, and shipping.

[0018] 5. Disassembling and assembling the corresponding winding rollers according to the corresponding winding requirements makes the operation of the equipment more convenient 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 foils of different lengths or thicknesses, the disassembly and assembly operations can be carried out quickly, reducing equipment adjustment time and improving production efficiency. Moreover, it is convenient to disassemble and replace after winding, which is conducive to quickly switching different production tasks or performing maintenance and replacement of the winding rollers.

Furthermore, an arc-shaped roller body is formed by arranging multiple cutting wheels 668 for receiving the copper foil, and it is beneficial to adjust the relative position with the cutter 665 according to the cutting width;

[0044] Then the copper foil is conveyed rightward through the upper wall surface of the cutting wheel 668. At this time, the adjusting screw 65 can be rotated to drive the second bearing 64 on the lifting seat 63 to descend, that is, drive the cutter 665 on the tool bar 661 to descend and press on the upper surface of the copper foil, and the cutter 665 applies force to the cutting wheel 668 for cutting; that is, driven by the first motor 662, the tool bar 661 and the cutter 665 are driven to rotate counterclockwise for cutting by means of the transmission of the first belt pulley 663 and the first belt 664; and the position and quantity of the cutter 665 are adjusted according to the cutting requirements, and then it can be fixed by means of the fastening bolt 666;

[0045] The working principle of the guiding structure 5 is described as follows:

[0046] After the copper foil passes through the cutter 665 and the cutting wheel 668, it will be slit into different widths. After the slit copper foil passes through the lower wall of the guiding rod 54 in the guiding structure 5, the copper foil with the corresponding width can be connected to the winding roller 78 in the winding structure 7 for winding, while the copper foil with other widths passes through the upper wall surface of the cutting wheel 668 of the next processing mechanism again, and is cut, guided and wound again by the cutter 665;

[0047] During the winding and conveying process, as the copper foil moves rightward, the guiding rod 54 will be stressed and rotate by means of the first bearing 53, and the distance between the guiding rod 54 and the cutter 665 can be adjusted by moving the first shaft seat 51 through the first socket 83 on the cross frame 4, and then it can be tightly fixed by the first bolt 52;

[0048] The working principle of the winding structure 7 is described as follows:

[0049] The slit copper foil forms corresponding width dimensions, and then one end of it is connected to the winding roller 78 with the corresponding length. By driving the second motor 75, the locking shaft 741 is driven to rotate by means of the transmission of the second belt pulley 76 and the second belt 77 through the fourth bearing 73, and then the winding roller 78 is limited and driven to rotate for winding by means of the locking assembly 74;

[0050] The distance between the coiling roller 78 and the guiding rod 54 can be adjusted by moving the third socket 85 under the third shaft seat 71 left and right on the cross frame 4, and then fixing it tightly with the third bolt 72.

[0051] For the replacement of the coiling roller 78, by applying force relatively to press the locking claw 745, the locking claw 745 is stressed and undergoes relative translation with the aid of the moving groove at the other end of the locking shaft 741 and the slide rods 743 on both sides of the bearing block 742. As the locking claw 745 moves relatively, the spring 744 will be compressed. When the other end of the locking claw 745 is received into the other end of the locking shaft 741, the other end of the locking shaft 741 can be inserted into the rectangular groove 95 of the coiling roller 78, and then the locking claw 745 is moved reversely to reset under the action of the spring 744, prompting the other end of the locking claw 745 to be inserted into the clamping groove 96 on the inner wall of the rectangular groove 95 for clamping and locking to complete the installation and replacement. If it is to be disassembled after coiling, the same operation as above can be carried out.

[0052] Generally speaking, the equipment is supported by the base 1, controlled by the controller 2, and the cross frame 4 is supported and installed by the support rod 3. The cross frame 4 can be spliced and extended relatively for adding multiple processing mechanisms. Each processing mechanism includes a cutting structure 6, a guiding structure 5, and a coiling structure 7. A single processing mechanism can realize the cutting, guiding, and coiling of copper foil. According to different production requirements, multiple processing mechanisms can perform hierarchical cutting and coiling, which is beneficial for the adjustment of the width range and the differentiated coiling. Each cutting structure 6 can also set the number of cutting knives 665 according to requirements to increase the cutting width adjustment.

[0053] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
