Description

Technical Field

[0001] This utility model relates to the field of current collector slitting and rewinding technology, and in particular to a current collector slitting and rewinding mechanism. Background Technology

[0002] In the production processes of batteries, electronic components, and other fields, current collectors, as one of the core substrates, need to be slit into the required specifications and rewound by a slitting and rewinding mechanism for subsequent processing. During the conveying process of the current collector on the guide rollers, if the current collector surface is wide, the force on the roller surface is prone to unevenness, and the tension control becomes more difficult, leading to wrinkles on the current collector surface. These wrinkles not only affect the accuracy of subsequent slitting, resulting in insufficient edge smoothness of the slit current collector, but also cause poor adhesion between current collector layers during rewinding. This leads to problems such as loose winding and misalignment in the finished product, which in turn affects the normal operation of subsequent processes and may even result in the scrapping of the finished product, increasing production costs.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0021] The following is combined Figures 1 to 6 The embodiments of this utility model are described below.

[0022] This utility model embodiment provides a current collector slitting and rewinding mechanism, including: 100 racks; The guide assembly includes a first guide roller 201, a second guide roller 202, a third guide roller 203, a fourth guide roller 204 and a fifth guide roller 205 arranged sequentially on the frame 100 along the current collector travel direction. The first guide roller 201 has a plurality of annular grooves spaced apart along its axial direction on its roller surface. A cutting assembly is located above the fifth guide roller 205, and the cutting assembly includes a plurality of cutting blades 301 spaced apart along the axial direction of the fifth guide roller 205; The upper winding assembly is disposed on the side of the fifth guide roller 205 away from the fourth guide roller 204. The upper winding assembly includes a plurality of upper winding rollers 401 that are coaxially arranged and spaced apart along the axial direction. The lower take-up assembly is located on the side of the fifth guide roller 205 away from the fourth guide roller 204. The lower take-up assembly includes a plurality of coaxially arranged and axially spaced lower take-up rollers 501. The upper take-up roller 401 and the lower take-up rollers 501 are staggered axially.

[0023] In this current collector slitting and rewinding mechanism, the first guide roller 201, the second guide roller 202, the third guide roller 203, the fourth guide roller 204 and the fifth guide roller 205 in the guiding assembly are arranged in sequence along the direction of current collector travel. Their core function is to guide the current collector to be stably transported along a preset path, providing the prerequisite for the precise slitting of the subsequent cutting assembly. The first guide roller 201 has several annular grooves spaced axially on its surface, which can axially position and disperse the tension of the current collector during transport, reducing wrinkles during transport. Especially when processing wide current collectors, which are more susceptible to wrinkles due to uneven tension or path deviation, the annular groove structure has a more prominent wrinkle-suppressing effect, ensuring that the current collector enters the subsequent slitting stage in a flat state. The second guide roller 202, third guide roller 203, fourth guide roller 204, and fifth guide roller 205 further assist in guiding the current collector, keeping it stable during travel and avoiding the impact of transport path fluctuations on slitting accuracy. The fourth guide roller 204 can also have several annular grooves spaced axially on its surface, working in synergy with the first guide roller 201 to further enhance tension control of the current collector. Even when the current collector is wide, it can effectively prevent new wrinkles from forming before it reaches the fifth guide roller 205 due to path extension or tension fluctuations, ensuring that the current collector remains flat before slitting. The cutter assembly is positioned above the fifth guide roller 205 and can axially cut the current collector passing through the fifth guide roller 205, dividing the original current collector into multiple slit current collectors that meet the subsequent winding requirements. The upper winding assembly and the lower winding assembly are both positioned on the side of the fifth guide roller 205 away from the fourth guide roller 204, and are respectively responsible for winding the slit current collectors. The upper winding rollers 401 of the upper winding assembly are coaxially arranged and spaced apart along the axial direction, and the lower winding rollers 501 of the lower winding assembly are also coaxially arranged and spaced apart along the axial direction. This spaced distribution design allows each slit current collector to correspond to one winding roller, avoiding multiple current collectors from winding together on the same winding roller. At the same time, the upper winding rollers 401 and lower winding rollers 501 are staggered along the axial direction to avoid mutual interference between the upper and lower winding assemblies during the winding process. This also ensures that each slit current collector can correspond to an independent winding roller, achieving orderly winding. This is especially suitable for scenarios where multiple rolls of current collectors with a wide width are wound synchronously after slit, improving winding efficiency and winding quality.

[0024] Furthermore, the upper winding assembly also includes a sixth guide roller 402, a seventh guide roller 403, and an eighth guide roller 404 arranged sequentially between the fifth guide roller 205 and the upper winding roller 401 along the current collector travel direction. The eighth guide roller 404 has a plurality of annular grooves spaced apart along its axial direction on its roller surface. The lower winding assembly also includes a ninth guide roller 502, a tenth guide roller 503, and an eleventh guide roller 504 arranged sequentially between the fifth guide roller 205 and the lower winding roller 501 along the current collector travel direction. The eleventh guide roller 504 has a plurality of annular grooves spaced apart along its axial direction on its roller surface.

[0025] In the upper take-up assembly, the sixth guide roller 402, the seventh guide roller 403, and the eighth guide roller 404 are sequentially arranged between the fifth guide roller 205 and the upper take-up roller 401 along the direction of the current collector's travel. These three rollers work together to guide the slit current collector precisely to each upper take-up roller 401, preventing the slit current collector from shifting or tangling during transport. The annular grooves spaced axially on the surface of the eighth guide roller 404 provide precise axial positioning of the slit current collector, effectively suppressing deviation and wrinkling during transport, especially for narrower slit current collectors, ensuring they enter the upper take-up rollers 401 smoothly. The lower take-up assembly functions similarly; the upper and lower take-up assemblies work together to achieve synchronous and stable transport of the slit current collectors on both the upper and lower take-up sides.

[0026] Furthermore, the current collector slitting and rewinding mechanism also includes two first linear motion components. The first linear motion components are disposed on the frame 100. The eighth guide roller 404 and the eleventh guide roller 504 are respectively mounted on the movable part of one of the first linear motion components. The eighth guide roller 404 is driven by the first linear motion component to approach or move away from the upper take-up roller, and the eleventh guide roller 504 is driven by the first linear motion component to approach or move away from the lower take-up roller.

[0027] In this embodiment, taking the eighth guide roller 404 as an example, the first linear motion component is used to drive the eighth guide roller 404 to move, so as to flexibly adjust the distance between the eighth guide roller 404 and the upper take-up roller 401 to adapt to the take-up tension requirements of the current collector. One first linear motion assembly is provided on each of the frames 100 at both ends of the eighth guide roller 404. The first linear motion assembly includes a first guide rail 601, a first slider 602, a first lead screw 603, and a first nut. The first guide rail 601 is fixedly mounted on the frame 100 and extends along the forward and backward direction of the current collector. The first slider 602 is movably mounted on the first guide rail 601. The first nut is connected to the first slider 602. The first lead screw 603 is threadedly engaged with the first nut, driving the first slider 602 to move forward and backward along the first guide rail 601. Both ends of the eighth guide roller 404 are respectively connected to the first slider 602 in one of the first linear motion assemblies. The two first linear motion assemblies are synchronously driven by a first servo motor 604 and a transmission rod 605. The first servo motor 604 is connected to the transmission rod 605, and the transmission rod 605 is connected to the first lead screw 603 in each of the two first linear motion assemblies (power transmission is achieved through couplings or gear meshing). Similarly, in this embodiment, the first linear motion component used to drive the eleventh guide roller 504 has the same structure as described above, except that its installation position corresponds to the lower winding component.

[0028] Furthermore, the current collector slitting and rewinding mechanism also includes a second linear motion component, which is disposed on the frame 100. The fourth guide roller 204 is mounted on the movable part of the second linear motion component, and the fourth guide roller 204 is driven by the second linear motion component to move closer to or away from the fifth guide roller 205.

[0029] In this embodiment, the second linear motion component adopts a lead screw drive structure. One second linear motion component is provided on each of the two ends of the frame 100 of the fourth guide roller 204. The second linear motion component includes an adjusting handwheel 701, a second guide rail 702, a second lead screw 703, a second nut, and a second slider 704. The second guide rail 702 is fixedly installed on the frame 100 and extends in the vertical direction. The second slider 704 is movably installed on the second guide rail 702. The adjusting handwheel 701 is located at one end of the second lead screw 703. The second nut is connected to the second slider 704. The second lead screw 703 and the second nut are threaded together, driving the second slider 704 to move up and down along the second guide rail 702. The two ends of the fourth guide roller 204 are respectively connected to the second slider 704 in one of the second linear motion components. During actual adjustment, the operator rotates the adjusting handwheel 701, causing the second lead screw 703 to rotate synchronously. Through the threaded transmission between the second lead screw 703 and the second nut, the rotational motion is converted into linear motion of the second slider 704 along the vertical guide rail, which in turn drives the fourth guide roller 204 to move up and down, thus adjusting the distance between the fourth guide roller 204 and the fifth guide roller 205. The second guide rail 702 has graduations, allowing the operator to visually read the adjustment amount and ensure consistent adjustment at both ends of the fourth guide roller 204. Adjusting the position of the fourth guide roller 204 optimizes the tension distribution of the current collector.

[0030] Furthermore, the upper take-up assembly also includes a third linear motion assembly, a plurality of first upper take-up roller seats 405 and a plurality of second upper take-up roller seats 406. The third linear motion assembly is disposed on the frame 100 and includes a plurality of movable parts. The first upper take-up roller seats 405 and the second upper take-up roller seats 406 are alternately disposed on the movable parts of the third linear motion assembly. The two ends of the upper take-up roller 401 are respectively mounted on the first upper take-up roller seats 405 and the second upper take-up roller seats 406. The first upper take-up roller seats 405 and the second upper take-up roller seats 406 are respectively driven by the third linear motion assembly to move along the axial direction of the upper take-up roller 401.

[0031] In this embodiment, the third linear motion component includes a third guide rail 801, which is fixedly mounted on the frame 100. The third guide rail 801 extends along the axial direction of the upper take-up roller 401. Taking the first upper take-up roller seat 405 as an example, several third sliders 802 are movably mounted on the third guide rail 801. The first upper take-up roller seat 405 is mounted on the third sliders 802, and the third sliders 802 are equipped with hand cranks 803. The third sliders 802 are driven to move along the third guide rail 801 through a gear and rack transmission structure. The second upper take-up roller seat 406 is configured similarly. During actual adjustment, the operator needs to move the first upper take-up roller seat 405 or the second upper take-up roller seat 406 by rotating the corresponding hand crank 803. Since the first upper take-up roller seat 405 and the second upper take-up roller seat 406 are respectively connected to the independent third slider 802, the two types of roller seats can be moved axially independently by rotating the corresponding hand crank 803. For example, when installing or removing the upper take-up roller 401, the corresponding first upper take-up roller seat 405 and the second upper take-up roller seat 406 can be moved to the sides to quickly expand the installation space and complete the installation or removal operation of the upper take-up roller 401.

[0032] Furthermore, the upper take-up assembly also includes an upper pressure roller guide rail 901 and several upper pressure roller assemblies. The upper pressure roller guide rail 901 is disposed on the frame 100 and extends axially along the upper take-up roller 401. The upper pressure roller assembly includes an upper pressure roller slider 902, an upper pressure roller cylinder 903, an upper pressure roller swing arm 904, an upper pressure roller seat 905, and an upper take-up pressure roller 906. The upper pressure roller slider 902 is movably disposed on the upper pressure roller guide rail 901. One end of the wheel swing arm 904 is rotatably mounted on the upper pressure roller slider 902, the upper pressure roller seat 905 is mounted on the other end of the upper pressure roller swing arm 904, the upper take-up pressure roller 906 is mounted on the upper pressure roller seat 905, the upper pressure roller cylinder 903 is mounted on the upper pressure roller slider 902, and the output end of the upper pressure roller cylinder 903 is connected to the upper pressure roller swing arm 904 via a connecting rod, thereby driving the upper take-up pressure roller 906 to abut against or move away from the upper take-up roller 401.

[0033] In this embodiment, the upper pressure roller slider 902 is movably mounted on the upper pressure roller guide rail 901 via a sliding fit, allowing the upper pressure roller assembly to move flexibly along the axis of the upper pressure roller guide rail 901 to adapt to the position of the upper take-up roller 401. In this embodiment, one end of the upper pressure roller swing arm 904 is hinged to the upper pressure roller slider 902 via a rotating shaft, allowing the swing arm to rotate freely around the hinge point; the other end of the upper pressure roller swing arm 904 is fixedly mounted with an upper pressure roller seat 905, and the upper take-up roller 906 is rotatably mounted in the upper pressure roller seat 905 via a bearing, ensuring that the upper take-up roller 906 can roll synchronously with the upper take-up roller 401. When assisted winding is required, the output end (piston rod) of the upper pressure roller cylinder 903 extends, and pushes the upper pressure roller swing arm 904 around the hinge point to rotate towards the upper winding roller 401 until the upper winding pressure roller 906 is in close contact with the surface of the coiled material on the upper winding roller 401. The pressure of the pressure roller eliminates the gap between the layers of the coiled material, ensuring the tightness of the winding. When it is necessary to change the roller or adjust the winding state, the output end (piston rod) of the cylinder retracts, and pulls the upper pressure roller swing arm 904 away from the upper winding roller 401 through the connecting rod, so that the upper winding pressure roller 906 is separated from the surface of the coiled material.

[0034] Furthermore, the lower take-up assembly also includes a fourth linear motion assembly, a plurality of first lower take-up roller seats 501 and a plurality of second lower take-up roller seats 501. The fourth linear motion assembly is mounted on the frame 100 and includes a plurality of movable parts. The first lower take-up roller seats 501 and the second lower take-up roller seats 501 are alternately arranged on the movable parts of the fourth linear motion assembly. The two ends of the lower take-up roller 501 are respectively mounted on the first lower take-up roller seats 501 and the second lower take-up roller seats 501. The first lower take-up roller seats 501 and the second lower take-up roller seats 501 are respectively driven by the fourth linear motion assembly to move along the axial direction of the lower take-up roller 501.

[0035] The design of the lower winding assembly in this embodiment is the same as that of the lower winding assembly described above, and will not be repeated here.

[0036] Furthermore, the lower take-up assembly also includes a lower pressure roller guide rail and several lower pressure roller assemblies. The lower pressure roller guide rail is disposed on the frame 100 and extends axially along the lower take-up roller 501. The lower pressure roller assembly includes a lower pressure roller slider, a lower pressure roller cylinder, a lower pressure roller swing arm, a lower pressure roller seat, and a lower take-up pressure roller 907. The lower pressure roller slider is movably disposed on the lower pressure roller guide rail. One end of the lower pressure roller swing arm is rotatably disposed on the lower pressure roller slider. The lower pressure roller seat is disposed at the other end of the lower pressure roller swing arm. The lower take-up pressure roller 907 is mounted on the lower pressure roller seat. The lower pressure roller cylinder is disposed on the lower pressure roller slider. The output end of the lower pressure roller cylinder is connected to the lower pressure roller swing arm via a connecting rod, thereby driving the lower take-up pressure roller 907 to abut against or move away from the lower take-up roller 501.

[0037] The design of the lower pressure roller guide rail and lower pressure roller assembly in this embodiment is the same as that of the lower winding assembly described above, and will not be repeated here.

[0038] Furthermore, the cutter assembly also includes a cutter slide rail 302 and a plurality of cutter sliders 303. The cutter slide rail 302 is fixedly mounted on the frame 100 and is located above the fifth guide roller 205. The cutter slide rail 302 extends axially along the fifth guide roller 205. The cutter sliders 303 are movably mounted on the cutter slide rail 302 and move along the cutter slide rail 302. The cutter 301 is mounted on the cutter sliders 303.

[0039] During operation, the distance between each cutter 301 can be flexibly adjusted by pushing the cutter slider 303 along the slide rail to adapt to the cutting needs of different width current collectors.

[0040] Furthermore, the current collector slitting and rewinding mechanism also includes a dust blowing assembly, which is used to blow away the debris generated during current collector slitting.

[0041] Slitting operations can easily generate fine debris. If this debris remains on the surface of the collector, it will affect the quality of subsequent use. Accumulation in the gaps between equipment may also interfere with operation. The dust blowing component is connected to an external air source and can blow away this debris with airflow, ensuring the surface of the collector is clean and maintaining a clean internal environment, thus ensuring the stability of the slitting and rewinding process.

[0042] The preferred embodiments of the present invention have been described in detail above, but the present disclosure is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of the present disclosure.
