Description

Technical Field

[0001] The present invention relates to the technical field of winding devices, and in particular to a double-station automatic winding device compatible with gap winding and center surface winding. Background Art

[0002] Common foil materials used for the positive and negative electrodes of lithium batteries include aluminum foil, copper foil, composite aluminum foil, and composite copper foil. Carbon-coated foil for lithium battery positive and negative electrodes is produced through a gravure coating process. During coating, the foil undergoes unwinding, coating, and drying, before a rewinding mechanism provides power for its movement and ultimately winds it into a finished coil that meets the required specifications. During the rewinding process, the foil acts both as the object being processed and as a transmission element, transmitting motion and power. Foil is characterized by its length being much greater than its width, and its width being much greater than its thickness. It is neither rigid nor purely elastic, exhibiting strong viscoelastic properties, resulting in complex dynamic and motion characteristics.

[0003] Existing dual-station winding mechanisms for gravure coating machines all utilize a relatively simple center-winding design. The winding shaft is directly driven by a motor, and the torque acting on the reel is transmitted layer by layer through the web. The main functional components of the dual-station automatic winding mechanism include the A / B winding shafts, a roll-changing turret, a roll-changing cutter arm, and a foil support roller assembly. During a roll change, the A / B winding shafts are flipped and switched to the roll-changing position via the turret. The roll-changing cutter arm is raised from the bottom, and the adhesive roller presses the foil onto the empty roll shaft in the roll-changing position. Simultaneously, the cutter cuts the full foil roll, completing the transition from a full roll to an empty roll.

[0004] When inspecting whether the carbon coated foil coil is qualified finished coil after winding, it is judged based on its shape, size, uniformity and appearance.

[0005] 1. Qualified shape and size means that the coil has good roundness and flat sides, and the diameter and length meet the requirements.

[0006] 2. Good uniformity and appearance means that the density of the coil is uniform, neither too loose nor too tight, and the appearance has no obvious flaws and defects.

[0007] The existing winding mechanism has the following undesirable phenomena due to its central winding mode; lower cutter swing arm mechanism; deviations in the width, thickness, and pattern of the incoming foil; different raw material formulas during carbon coating; and variations in the size of the carbon coating stripes:

[0008] 1. In the center winding mode, as the coil diameter changes, to ensure a constant material tension or a taper change, the rotational speed must vary inversely with the coil diameter and the torque change must be proportional to the coil diameter. At the same time, the torque acting on the center winding reel is transmitted layer by layer through the wound material. If the winding tension is too small, it is more likely to cause in-layer slippage, resulting in uneven winding end faces and winding misalignment. If the winding tension is too large and the winding is too tight, it will cause wrinkles in the blank area of the tab, which is a defect of mutual adhesion between foil materials. An overly tight coil will also cause high residual stress inside the material. During the storage of the wound material, the stress will cause deformation of the coil. The complex and variable tension control directly affects the quality of the finished product.

[0009] 2. As the width of the foil increases, the pattern quality deteriorates. After carbon coating, the foil is more likely to wrinkle in the blank area of the tab, and the end face of the coil will collapse. During the unwinding process in subsequent processes, the wrinkles in the blank area of the tab are likely to cause the foil to wrinkle during unwinding, and the end face collapse will cause the edge of the foil to crack during unwinding, resulting in tape breakage.

[0010] 3. When changing the coil in the lower cutter swing arm mechanism, the lifting heights of the left and right swing arms may be inconsistent when the cutter swing arm is lifted, resulting in the gluing roller not being parallel to the winding reel. During coil change, the bottom layer is poorly adhered, the bottom coil wrinkles and needs to be manually eliminated, resulting in serious waste of the bottom coil. At the same time, there are potential safety hazards.

[0011] 4. After the cutter swing arm is lifted in place, when the gluing roller pops out during coil change, it impacts the winding reel, disrupting the stability of the foil running, resulting in misalignment at the bottom of the winding.

[0012] 5. As the winding speed increases, it becomes more difficult to discharge the air entering the foil winding. The wound material is not tight enough, resulting in winding slippage and end face misalignment. Simply increasing the winding tension will cause the outer layer tension of the wound material to be greater than the internal tension, resulting in internal extrusion of the coil, causing collapse, core pulling and other defects.

The telescopic movements of the two cutter cylinders are used to control the cutter to move towards and away from the winding part of the turret unit.

[0019] In one embodiment, the turret unit includes a flipping drive mechanism, turret wallboards, an A winding air shaft assembly, and a B winding air shaft assembly; the two flipping drive mechanisms are arranged on the winding base in a separated and opposite manner, and the rotatable turret wallboards are installed on both of the two flipping drive mechanisms. The flipping drive mechanism is used to control the rotation of the turret wallboards; an actively rotatable A winding air shaft assembly and an actively rotatable B winding air shaft assembly are connected between the two turret wallboards; when the flipping drive mechanism controls the rotation of the turret wallboards, the turret unit is used to switch one of the A winding air shaft assembly and the B winding air shaft assembly to the winding part of the turret unit.

[0020] In one embodiment, the turret unit includes an A-axis flattening roller assembly that can press towards and away from the A winding air shaft assembly, and a B-axis flattening roller assembly that can press towards and away from the B winding air shaft assembly.

[0021] In one embodiment, the A-axis flattening roller assembly includes an A-axis flattening swing arm, an A-axis flattening roller, and an A-axis flattening cylinder. The A-axis flattening swing arm is rotatably installed on the turret wallboard. One end of the A-axis flattening swing arm is provided with the rotatable A-axis flattening roller, and the other end of the A-axis flattening swing arm is rotatably connected to the telescopic end of the A-axis flattening cylinder.

The telescopic movement of the B-axis flattening cylinder is used to control the B-axis flattening roller to move towards and away from the B winding air shaft assembly.

[0022] In one embodiment, support roller assemblies are connected between the upper parts and the lower parts of the two turret wallboards.

[0023] In one of the embodiments, along the conveying path of the foil, the guiding roller group includes a first turning roller, a tension roller, a traction roller, a traction pressure roller, a second turning roller, a third turning roller, a floating swing roller, a fourth turning roller, and a fifth turning roller arranged in sequence.

[0024] The beneficial effects of the present invention are as follows:

[0025] It is not difficult to conclude that the tension used by the winding mechanism of the present invention that adopts the compatible gap winding and center surface winding methods is less than that of the conventional center winding, which significantly improves the wrinkling in the middle tab area. The constant-spacing gap winding can keep the winding angle of the foil from the approaching roller to the winding shaft constant, ensuring the flat winding of the foil. The roll-changing unit drives the approaching roller in a stable manner to advance, precisely controls the approaching position, the roll-changing process is stable, and the winding bottoming effect is significantly improved. The pressure exerted by the A-axis flattening pressure roller assembly or the B-axis flattening pressure roller assembly on the surface of the wound material is further reduced, which reduces the pressure on the surface of the foil while meeting the exhaust requirement, and improves the tab wrinkling. The large coil diameter tension taper value decreases, and the wound material is tight inside and loose outside, solving the problem of end face collapse.

[0026] Furthermore, during gap winding, by using the cooperation of tension control and the approaching roller, the tension of the coil can be precisely controlled to ensure that the coil remains tight and neat during the winding process. Specifically: after a stable roll change, the motor controls the roll-changing unit to retreat, and winds with a certain gap from the winding shaft. As the winding progresses, the roll-changing unit retreats synchronously to keep the gap unchanged, ensuring that the angle of the foil entering the winding shaft remains constant and the relative position remains unchanged during winding, so as to reduce the wrinkles in the tab blank area caused by uneven tension during the winding of the foil and improve the surface flatness of the wound material.

[0027] In addition, when using center surface winding, after the roll-changing unit drives the approaching roller to change the roll, it continues to contact the winding shaft without retreating. At this time, the wound material is driven by both the center winding shaft and further driven and fixed by the frictional force generated by the surface contact with the approaching roller, thereby realizing center surface winding.

[0028] Furthermore, the surface of the wound material contacts the approaching roller and is further driven and fixed by the frictional force. The surface winding part is mainly used to assist winding, maintain the flatness and stability of the wound material, and at the same time reduce the deformation and wrinkling of the wound material. During the winding process, the center winding and the surface winding cooperate with each other to jointly complete the winding work of the foil.

[0029] By selecting different winding methods and adjusting winding parameters such as tension, speed, pressure, etc., precise winding of wound materials of different materials and different thicknesses can be achieved, thereby realizing the winding of different foils such as carbon-coated aluminum foil, carbon-coated copper foil, carbon-coated composite aluminum foil, and carbon-coated composite copper foil.

[0030] In addition, during high-speed winding, after the winding unit to be replaced changes the roll smoothly, control the flattening pressure roller assembly of axis A or the flattening pressure roller assembly of axis B to press onto the surface of the wound material, and timely discharge the air that enters the wound material during winding, making the winding tighter. At the same time, as the roll diameter increases, the pressure of the flattening pressure roller assembly of axis A or the flattening pressure roller assembly of axis B on the wound material can be adjusted in real time.

[0031] The above-mentioned multiple measures effectively solve the problems that the low-tension wound material is not tight enough during winding, resulting in winding slippage and end face misalignment; solve the problem that the large tension during winding causes large tension on the outer layer and internal tension of the wound material, resulting in internal extrusion of the roll, collapse, core pulling and other defects; solve the problem of bottom wrinkling and poor bottoming during roll change; solve the problem that during high-speed winding, the surface of the wound material is wrinkled due to difficult air exhaust of the wound material, reducing the deformation and wrinkling of the wound material.

Detailed implementation manners

[0055] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0056] The present invention provides a dual-station automatic winding device compatible with gap winding and central surface winding. As shown in the embodiments, Figure 1 it includes a winding base 10, and a guiding roller group 20, a roll changing unit 30, and a turret unit 40 provided on the winding base 10.

[0057] Regarding the winding base 10, it is mainly used to install and fix each main unit and component. It only needs to ensure that the components are firmly and stably installed, and there are no special design requirements. For example, in this embodiment, in order to install and fix the guiding roller group 20 and the roll changing unit 30, Figure 1 and Figure 2 the setting method shown in the figure is adopted. At this time, two separated and relatively arranged roll changing wallboards 11 are provided on the winding base 10. The guiding roller group 20 and the roll changing unit 30 are fixedly installed between the two roll changing wallboards 11. A part of the guiding roller group 20 is arranged beside the roll changing unit 30, and the rest is arranged below the roll changing unit 30.

[0058] Regarding the guiding roller group 20, as Figures 1 to 3 shown in the figure, in this embodiment, the guiding roller group 20 is provided to guide and convey the foil to the roll changing unit 30. Therefore, to achieve this purpose, along the conveying track of the foil, this embodiment sets the guiding roller group 20 to include a first deflector roll 21, a tension roller 22, a traction roller 23, a traction pressure roller 24, a second deflector roll 25, a third deflector roll 26, a floating swing roll 27, a fourth deflector roll 28, and a fifth deflector roll 29 arranged in sequence. Therefore, after adopting this setting method, the foil can be first conveyed to the first deflector roll 21, and then the conveying track of the foil is arranged as shown in the figure, and the foil can be smoothly conveyed to the roll changing unit 30.

[0059] Regarding the roll changing unit 30, as Figure 2 and Figure 4 shown in the figure, in this embodiment, the roll changing unit 30 is set to include a roll changing frame 31 connected and fixed to the winding base 10, a gap adjusting component 32 provided on the roll changing frame 31, a deflector roll component 33 provided on the side of the gap adjusting component 32 away from the turret unit 40, and a proximity roll component 34 and a cutter component 35 provided on the side of the gap adjusting component 32 adjacent to the turret unit 40.

[0060] Regarding the roll changing frame 31, as Figure 2 and Figures 4 to 6 shown in the figure, in this embodiment, the roll changing frame 31 is set to include two separated and relatively arranged frame plates 311. The two frame plates 311 are respectively fixedly installed on the two roll changing wallboards 11. Therefore, by installing the remaining components of the roll changing unit 30 on the two frame plates 311, the installation and fixation of the remaining components of the roll changing unit 30 can be achieved.

[0061] For the gap adjustment assembly 32, as Figures 2 to 7 shown, in this embodiment, the gap adjustment assembly 32 is configured to be movable towards and away from the turret unit 40; thus, to achieve this purpose, in this embodiment, linear guide rails 312 and racks 313 arranged in parallel are respectively provided on two frame plates 311, and sliders 314 are slidably mounted on both linear guide rails 312; then, the gap adjustment assembly 32 is provided to include a drive motor 321, a speed reducer 322, two slide plates 323 respectively mounted on the two sliders 314, a pull rod 324 connected between the two slide plates 323, and a transmission shaft 325 rotatably provided between the two slide plates 323. At this time, the output shaft of the drive motor 321 is connected to the power input end of the speed reducer 322, the power output end of the speed reducer 322 is connected to the transmission shaft 325, and transmission gears 326 are respectively provided at both ends of the transmission shaft 325, and the two transmission gears 326 are respectively engaged with the two racks 313.

[0062] After adopting the above setting method, the speed reducer 322 can convert the high-speed rotation of the drive motor 321 into low-speed rotation, and drive the transmission shaft 325 to rotate self-rotation with this. When the transmission shaft 325 drives the transmission gears 326 to rotate self-rotation together, the transmission gears 326 drive through meshing with the racks 313, and can provide a driving force for the gap adjustment assembly 32, so that the gap adjustment assembly 32 can achieve linear reciprocating movement under the limiting and guiding action of the slider 314 and the linear guide rail 312.

[0063] Therefore, if the forward rotation of the drive motor 321 can control the gap adjustment assembly 32 to move towards the turret unit 40, then the reverse rotation of the drive motor 321 can control the gap adjustment assembly 32 to move away from the turret unit 40, thus achieving the purpose of controlling the gap adjustment assembly 32 to move towards and away from the turret unit 40.

[0064] For the over-roller assembly 33, as Figures 2 to 5 shown, the over-roller assembly 33 is mainly used to realize the guiding and conveying of the foil material, so that the over-roller assembly 33 can be used to guide the foil material to the turret unit 40.

[0065] For the approaching-roller assembly 34, as Figures 2 to 5 shown, in this embodiment, the approaching-roller assembly 34 is provided to press the foil material against the winding part of the turret unit 40. To achieve this purpose, only a corresponding mechanism needs to be provided to provide a moving driving force for the approaching-roller assembly 34.

[0066] For example, in this embodiment, as Figures 2 to 5 , and Figure 8 and Figure 10As shown in the figure, the approaching roller assembly 34 is provided with an approaching roller 341, a rotating shaft roller 342, an approaching roller swing arm 343, and an approaching roller cylinder 344; the rotating shaft roller 342 is rotatably installed between two sliding plates 323; one ends of two approaching roller swing arms 343 are respectively connected and fixed to both ends of the rotating shaft roller 342, and the other ends of two approaching roller swing arms 343 are respectively rotatably connected to both ends of the approaching roller 341; two approaching roller cylinders 344 are respectively arranged on two sliding plates 323, and the telescopic ends of two approaching roller cylinders 344 are respectively rotatably connected to one ends of two approaching roller swing arms 343, and the telescopic movements of two approaching roller cylinders 344 are used to control the approaching roller 341 to move towards and away from the winding part of the turret unit 40.

[0067] After adopting this setting method, the rotating shaft roller 342 will become the swing axis of the approaching roller swing arm 343. At this time, if the telescopic end of the approaching roller cylinder 344 extends, it will push the approaching roller swing arm 343 towards the turret unit 40, so that the approaching roller 341 can move towards the turret unit 40; similarly, if the telescopic end of the approaching roller cylinder 344 contracts, it will pull the approaching roller swing arm 343 away from the turret unit 40, so that the approaching roller 341 can move away from the turret unit 40.

[0068] For the cutter assembly 35, as Figure 3 shown, in this embodiment, the cutter assembly 35 is provided for cutting the foil material. To achieve this purpose, only a corresponding mechanism needs to be set to provide a moving driving force for the cutter assembly 35.

[0069] For example, in this embodiment, as Figures 2 to 5 、 Figure 7 、 Figure 9 、and Figure 10 shown, the cutter assembly 35 is provided with a cutter 351, a cutter swing arm 352, and a cutter cylinder 353; one ends of two cutter swing arms 352 are respectively rotatably connected to two sliding plates 323, and a cutter 351 is connected between the other ends of two cutter swing arms 352; two cutter cylinders 353 are respectively arranged on two sliding plates 323, and the telescopic ends of two cutter cylinders 353 are respectively rotatably connected to the middle parts of two cutter swing arms 352, and the telescopic movements of two cutter cylinders 353 are used to control the cutter 351 to move towards and away from the winding part of the turret unit 40.

[0070] After adopting this setting method, the cutter swing arm 352 can use its rotation connection as the swing center. At this time, if the telescopic end of the cutter cylinder 353 extends, it will push the cutter swing arm 352 to rotate clockwise, so that the cutter 351 moves away from the foil. Similarly, if the telescopic end of the cutter cylinder 353 contracts at this time, it will pull the cutter swing arm 352 to rotate counterclockwise, so that the cutter 351 moves closer to the foil and cuts the foil.

[0071] Regarding the turret unit 40, as Figure 1 、 Figure 2 and Figure 12 shown, in this embodiment, the turret unit 40 is provided with a flipping drive mechanism 41, a turret wall panel 42, an A winding air shaft assembly 43 and a B winding air shaft assembly 44; the two flipping drive mechanisms 41 are arranged on the winding base 10 in a separated and opposite manner, and rotatable turret wall panels 42 are installed on both of the two flipping drive mechanisms 41. The flipping drive mechanism 41 is used to control the rotation of the turret wall panel 42; an actively rotatable A winding air shaft assembly 43 and an actively rotatable B winding air shaft assembly 44 are connected between the two turret wall panels 42; when the flipping drive mechanism 41 controls the rotation of the turret wall panel 42, the turret unit 40 is used to switch one of the A winding air shaft assembly 43 and the B winding air shaft assembly 44 to the winding position of the turret unit 40.

[0072] Therefore, during the winding operation, the positions of the A winding air shaft assembly 43 and the B winding air shaft assembly 44 can be adjusted according to different usage requirements; for example, if it is necessary to wind using the A winding air shaft assembly 43, the reel can be loaded on the A winding air shaft assembly 43, and then the flipping drive mechanism 41 is used to control the rotation of the turret wall panel 42 until the A winding air shaft assembly 43 moves to the winding position of the turret unit 40.

[0073] After the A winding air shaft assembly 43 has completed the winding operation, a new reel can be loaded on the B winding air shaft assembly 44, and then the flipping drive mechanism 41 is used to control the rotation of the turret wall panel 42 to swap the positions of the A winding air shaft assembly 43 and the B winding air shaft assembly 44, so that the B winding air shaft assembly 44 is placed at the winding position of the turret unit 40. At this time, the B winding air shaft assembly 44 can perform a new round of winding operation, while the A winding air shaft assembly 43 can perform the uncoiling operation.

[0074] It should be noted that to ensure the flatness of winding during the winding process, as Figure 2 and Figure 12As shown, in this embodiment, the turret unit 40 is provided with an A-axis flattening roller assembly 45 that can press towards and away from the A winding air shaft assembly 43, and a B-axis flattening roller assembly 46 that can press towards and away from the B winding air shaft assembly 44.

[0075] Specifically, at this time, the A-axis flattening roller assembly 45 includes an A-axis flattening swing arm 451, an A-axis flattening roller 452, and an A-axis flattening cylinder 453. The A-axis flattening swing arm 451 is rotatably installed on the turret wall panel 42. One end of the A-axis flattening swing arm 451 is equipped with a rotatable A-axis flattening roller 452. The other end of the A-axis flattening swing arm 451 is rotatably connected to the telescopic end of the A-axis flattening cylinder 453. The telescopic movement of the A-axis flattening cylinder 453 is used to control the A-axis flattening roller 452 to move towards and away from the A winding air shaft assembly 43.

[0076] After adopting the above setting method, if it is necessary to use the A winding air shaft assembly 43 for winding operation, then during the winding process, the A-axis flattening cylinder 453 can be used to apply a thrust to the A-axis flattening swing arm 451, so that the A-axis flattening swing arm 451 drives the A-axis flattening roller to press towards the A winding air shaft assembly 43 through rotation. By pressing the foil material towards the reel on the A winding air shaft assembly 43 with the A-axis flattening roller, the winding and flattening effect can be achieved.

[0077] Similarly, the B-axis flattening roller assembly 46 includes a B-axis flattening swing arm 461, a B-axis flattening roller 462, and a B-axis flattening cylinder 463. The B-axis flattening swing arm 461 is rotatably installed on the turret wall panel 42. One end of the B-axis flattening swing arm 461 is equipped with a rotatable B-axis flattening roller 462. The other end of the B-axis flattening swing arm 461 is rotatably connected to the telescopic end of the B-axis flattening cylinder 463. The telescopic movement of the B-axis flattening cylinder 463 is used to control the B-axis flattening roller 462 to move towards and away from the B winding air shaft assembly 44.

[0078] Similarly, after adopting the above setting method, if it is necessary to use the B winding air shaft assembly 44 for winding operation, then during the winding process, the B-axis flattening cylinder 463 can be used to apply a thrust to the B-axis flattening swing arm 461, so that the B-axis flattening swing arm 461 drives the B-axis flattening roller to press towards the B winding air shaft assembly 44 through rotation. By pressing the foil material towards the reel on the B winding air shaft assembly 44 with the B-axis flattening roller, the winding and flattening effect can be achieved.

[0079] It should be noted that during the design process, corresponding sensors can be set to monitor the contact situation between the flattening roller and the foil material, so as to adjust the telescopic amount of the flattening cylinder in a timely manner to ensure that the entire flattening operation can be adjusted according to the real-time situation.

[0080] Furthermore, as Figure 12As shown, in this embodiment, support roller assemblies 47 are connected between the upper and lower parts of the two turret wall plates 42 for supporting the foil during flipping.

[0081] Finally, during the winding operation, the roll change unit 30 can be used to control the approach roller assembly 34 to fit or maintain a constant distance from the winding part of the turret unit 40.

[0082] For example, from Figure 10 As can be seen, at this time, the gap adjustment assembly 32 controls the approach roller 341 to move towards the A winding air shaft assembly 43 so that the approach roller 341 fits the foil on the A winding air shaft assembly 43, and the operation of center surface winding can be achieved.

[0083] And from Figure 11 As can be seen, at this time, the gap adjustment assembly 32 controls the approach roller 341 to move towards the A winding air shaft assembly 43 and keeps the approach roller 341 always at a constant distance from the foil on the A winding air shaft assembly 43, and gap winding can be achieved.

[0084] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
