Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The copper foil slitting machine provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
The inventor finds that the current copper foil splitting machine comprises a wind-up roller and a regulating roller, the regulating roller is positioned in front of the wind-up roller, the split copper foil passes through the regulating roller and is then wound by the wind-up roller, but the current distance between the regulating roller and the wind-up roller is too large, so that the copper foil positioned between the regulating roller and the wind-up roller is too long, the suspension length of the part of copper foil between the regulating roller and the wind-up roller is too large, the tension of the copper foil positioned between the regulating roller and the wind-up roller is too small to shake, and the phenomenon of interlayer dislocation of the copper foil is caused.
As shown in fig. 1 to 3, the embodiment of the application discloses a copper foil slitting machine, which comprises an unreeling device 100, a guiding device 200, a slitting device 300 and a reeling device 400, wherein the reeling device 400 comprises a driving mechanism 410, and an adjusting roller 420 and a reeling roller 430 which are arranged at intervals, the adjusting roller 420 is arranged between the reeling roller 430 and the slitting device 300, the reeling roller 430 is used for reeling copper foil into a copper foil roll, the adjusting roller 420 can be in contact with the copper foil, and the horizontal distance between the adjusting roller 420 and the reeling roller 430 is in a first preset range so as to increase the tension of the copper foil between the adjusting roller 420 and the reeling roller 430. Optionally, the first preset range may be 30-100 mm. The horizontal distance between the regulating roller 420 and the wind-up roller 430 means the minimum distance between the regulating roller 420 and the wind-up roller 430 in the horizontal direction (the direction indicated by the x arrow line in fig. 3).
Specifically, the unreeling device 100 is used for releasing copper foil, the guiding device 200 is used for guiding the copper foil to the slitting device 300, the slitting device 300 is used for slitting the copper foil into at least two copper foils with smaller widths along the width direction of the copper foil, and the slit copper foil is wound into a copper foil roll by the winding roller 430 after being tensioned by the adjusting roller 420. The winding device 400 may include at least two winding rollers 430 to wind the slit at least two copper foils, respectively.
At least one of the conditioning roller 420 and the wind-up roller 430 is connected to the driving mechanism 410, and the driving mechanism 410 may drive at least one of the conditioning roller 420 and the wind-up roller 430 to continuously move so that the horizontal distance between the conditioning roller 420 and the copper foil roll is maintained within a second preset range, that is, the horizontal distance between the conditioning roller 420 and the copper foil roll is always maintained within the second preset range during the winding process, where the horizontal distance refers to: the minimum distance between the conditioning roller 420 and the copper foil roll in the horizontal direction (the direction indicated by the x arrow line in fig. 3). Optionally, the driving mechanism 410 may drive at least one of the adjusting roller 420 and the wind-up roller 430 to move along the arrangement direction of the copper foil splitting machine, so that the horizontal distance between the adjusting roller 420 and the copper foil coil is always kept within a second preset range, where the second preset range may be 30-100 mm.
It should be noted that, in the case where the driving mechanism 410 can drive the wind-up roller 430 to move, since the driving mechanism 410 can drive the wind-up roller 430 away from the adjusting roller 420 in the winding process, this can make the wind-up roller 430 pull the copper foil, in order to prevent the copper foil from being pulled and deformed, a loop storage assembly can be disposed between the slitting device 300 and the adjusting roller 420, so as to absorb the pulling force applied by the wind-up roller 430 to the copper foil, and thus prevent the copper foil from being pulled and deformed.
In the embodiment of the present application, the horizontal distance between the adjusting roller 420 and the wind-up roller 430 is within the first preset range, and the two are closely spaced, which can reduce the distance between the adjusting roller 420 and the wind-up roller 430, thereby reducing the length of the copper foil between the adjusting roller 420 and the wind-up roller 430, namely: the suspension length of the part of copper foil between the regulating roller 420 and the winding roller 430 is reduced to increase the tension of the part of copper foil, so that the part of copper foil can be prevented from shaking, and the phenomenon of interlayer dislocation can be avoided; in addition, since the diameter of the copper foil coil wound on the winding roller 430 is continuously increased during the winding process of the winding roller 430, the embodiment of the application sets the driving mechanism 410 to drive at least one of the winding roller 430 and the adjusting roller 420 to move so as to increase the interval between the winding roller 430 and the adjusting roller 420, thereby avoiding the interference between the copper foil coil and the adjusting roller 420; in addition, in the winding process, the embodiment of the application controls the horizontal distance between the regulating roller 420 and the copper foil coil within a second preset range, which can control the tension of the part of copper foil in the winding process within a certain range so as to avoid the larger change of the tension, thereby further preventing the phenomenon of interlayer dislocation during winding.
The copper foil is continuously wound on the copper foil roll during the winding process, and thus the diameter of the copper foil roll is continuously increased, and thus the tangent point between the copper foil and the copper foil roll between the conditioning roller 420 and the winding roller 430 is increased, and if the horizontal distance between the conditioning roller 420 and the copper foil roll is maintained or gradually increased, the length of the copper foil between the conditioning roller 420 and the winding roller 430 is gradually increased, which reduces the tension of the portion of the copper foil, thus weakening the effect of the present application for preventing occurrence of interlayer misalignment, and thus in an alternative embodiment, the horizontal distance between the conditioning roller 420 and the copper foil roll is configured to be gradually decreased during the winding process of the winding roller 430. In this embodiment, during the winding process of the wind-up roller 430, the horizontal distance between the adjusting roller 420 and the copper foil coil is gradually reduced, and compared with the previous embodiment, the present embodiment can reduce the height of the tangent point between the copper foil located between the adjusting roller 420 and the wind-up roller 430 and the copper foil coil, thereby shortening the length of the copper foil located between the adjusting roller 420 and the wind-up roller 430, increasing the tension of the copper foil, and ensuring the effect of preventing the occurrence of interlayer dislocation in the embodiment of the present application.
In an alternative embodiment, the regulating roller 420 includes a first regulating roller 421 and a second regulating roller 422 which are disposed at a distance and connected, the first regulating roller 421 is located between the second regulating roller 422 and the slitting device 300, a threading space is provided between the first regulating roller 421 and the second regulating roller 422, and the first regulating roller 421 and the second regulating roller 422 can each be in contact with the copper foil passing through the threading space. Specifically, since the first regulation roller 421 and the second regulation roller 422 are connected, the positions between the first regulation roller 421 and the second regulation roller 422 are relatively fixed, the relative movement of the two does not occur, and in the case where the driving mechanism 410 drives the regulation roller 420 to move, the driving mechanism 410 drives the first regulation roller 421 and the second regulation roller 422 to move at the same time; note that, the horizontal distance between the dancer 420 and the copper foil roll in this embodiment means: the second regulating roller 422 is at a minimum distance from the copper foil roll in the horizontal direction; the horizontal distance between the regulating roller 420 and the wind-up roller 430 means the minimum distance between the second regulating roller 422 and the wind-up roller 430 in the horizontal direction.
In this embodiment, the adjusting roller 420 includes a first adjusting roller 421 and a second adjusting roller 422, and the first adjusting roller 421 and the second adjusting roller 422 together tension the copper foil, compared with the embodiment in which the number of adjusting rollers 420 is only one, the embodiment can make the copper foil and the first adjusting roller 421 and the second adjusting roller 422 have larger wrap angles, so that the tension of the copper foil can be increased, so as to ensure the effect of preventing the interlayer dislocation in the embodiment of the application; in addition, after the first adjusting roller 421 and the second adjusting roller 422 are disposed, the distance between the adjusting roller 420 and the slitting device 300 can be shortened, so that the length of the copper foil between the first adjusting roller 421 and the slitting roller 310 of the slitting device 300 can be shortened, the tension of the copper foil between the first adjusting roller 421 and the slitting device 300 can be increased, and the slitting of the copper foil is facilitated. Of course, the number of the regulating rollers 420 may be one or more, which is not limited by the present application.
In an alternative embodiment, the copper foil is wound by the winding roller 430 from above the winding roller 430, that is, the winding manner of the winding device 400 is the winding manner, the tangent point between the copper foil and the copper foil roll between the winding roller 430 and the second regulating roller 422 is located at the upper side of the copper foil roll, and the lowest point of the first regulating roller 421 is higher than the lowest point of the second regulating roller 422 and lower than the highest point of the second regulating roller 422. In this embodiment, the lowest point of the first regulating roller 421 is located between the lowest point of the second regulating roller 422 and the highest point of the second regulating roller 422, that is, the position of the first regulating roller 421 is taken as a reference, the second regulating roller 422 is moved down, and since the copper foil is wound up by the winding roller 430 from above the winding roller 430, the slit copper foil sequentially passes through the upper side of the first regulating roller 421 and the lower side of the second regulating roller 422 and is then conveyed to the upper side of the winding roller 430 for winding, that is, the copper foil is located on the upper side of the first regulating roller 421 and is located on the lower side of the second regulating roller 422, so that after the second regulating roller 422 is moved down, the wrap angle between the copper foil and the first regulating roller 421 and the second regulating roller 422 can be increased, respectively, which can reduce the length of the copper foil located between the first regulating roller 421 and the second regulating roller 422 and the length of the winding roller 430, which can enable the copper foil located between the first regulating roller 421 and the second regulating roller 422 and the copper foil to be kept between the second regulating roller 422 and the copper foil to be further dislocated between the copper foil and the regulating roller 430. Of course, the lowest point of the first dancer 421 may be lower than the lowest point of the second dancer 422, which is not limiting of the present application.
In an alternative embodiment, referring to fig. 3, the red line in fig. 3 is copper foil, the radius of the first adjustment roller 421 is equal to the radius of the second adjustment roller 422, the vertical distance between the lowest point of the first adjustment roller 421 and the lowest point of the second adjustment roller 422 is a first distance L1, and the radius of the first adjustment roller 421 is greater than the first distance L1. In this embodiment, the first distance L1 is the distance for moving the second adjusting roller 422 downward, that is, the distance for moving the second adjusting roller 422 downward is smaller than the radius thereof, so that the second adjusting roller 422 is prevented from moving too much downward. If the distance of the second regulating roller 422 moving downward is too large, the wrap angle between the copper foil and the first regulating roller 421 and the second regulating roller 422 respectively will be too large, which increases the contact area between the copper foil and the first regulating roller 421 and the second regulating roller 422 respectively, so that a larger friction force acts on the copper foil, thereby generating more friction heat, and the copper foil may be deformed when heated; in addition, the wrap angle between the copper foil and the first and second regulating rollers 421 and 422, respectively, will be too large, so that the difference in tension of the copper foil when entering the first regulating roller 421 and leaving the second regulating roller 422 is too large, which may cause a phenomenon in which the surface of the copper foil is unevenly stretched, and the too large wrap angle may cause the edge portion of the copper foil to undergo more friction than the central portion, thereby causing the line speed of the edge of the copper foil to be inconsistent with the line speed of the center, which may also reduce the uniformity of the tension distribution. While this embodiment prevents the second dancer 422 from moving down too far, it solves the above-mentioned problem.
In an alternative embodiment, the lowest point of the second dancer 422 is higher than the lowest point of the wind-up roll 430 and lower than the highest point of the wind-up roll 430. In this embodiment, the lowest point of the second regulating roller 422 is located between the lowest point of the wind-up roller 430 and the highest point of the wind-up roller 430, that is, the position of the second regulating roller 422 is used as a reference, the wind-up roller 430 is moved down, and since the diameter of the copper foil coil is continuously increased in the winding process, the tangent point between the copper foil and the copper foil coil located between the second regulating roller 422 and the wind-up roller 430 is increased, the length of the copper foil is gradually increased, and the tension is gradually decreased, and in order to prevent the diameter of the copper foil coil from being increased, the tangent point between the copper foil and the copper foil coil is excessively increased, so that the wind-up roller 430 is moved down, and the length of the copper foil located between the second regulating roller 422 and the wind-up roller 430 is reduced, so that the tension of the copper foil is prevented from being reduced too much, and the phenomenon of interlayer dislocation during winding is further prevented.
In an alternative embodiment, the radius of the first dancer 421 is equal to the radius of the second dancer 422, the vertical distance between the lowest point of the first dancer 421 and the lowest point of the second dancer 422 is a first distance L1, the vertical distance between the lowest point of the second dancer 422 and the lowest point of the wind-up 430 is a second distance L2, and the first distance L1 is greater than the second distance L2. In this embodiment, the first distance L1 is greater than the second distance L2, so that the winding roller 430 is prevented from falling to an excessively low position, and the winding roller 430 falls to an excessively low position to make the initial tension of the copper foil excessively small during winding, which may weaken the effect of the present application for preventing interlayer misalignment.
In an alternative embodiment, the horizontal distance between the first dancer 421 and the second dancer 422 is less than the horizontal distance between the second dancer 422 and the wind-up 430. The horizontal distance between the first adjustment roller 421 and the second adjustment roller 422 means the minimum distance between the first adjustment roller 421 and the second adjustment roller 422 in the horizontal direction; the horizontal distance between the second regulating roller 422 and the wind-up roller 430, and the minimum distance between the second regulating roller 422 and the wind-up roller 430 in the horizontal direction.
Because the wind-up roller 430 rotates at a high speed during the winding process, which applies a pulling force to the copper foil, in this embodiment, the first adjusting roller 421 and the second adjusting roller 422 are separated relatively far, and the second adjusting roller 422 and the wind-up roller 430 are separated relatively far, so that the first adjusting roller 421 and the second adjusting roller 422 can provide stable initial tension for the copper foil, and the second adjusting roller 422 and the wind-up roller 430 are separated relatively far, which is helpful for reducing the pulling force applied to the copper foil by the wind-up roller 430, and reducing the risk of breakage of the copper foil caused by excessive tensioning of the copper foil; in addition, the relatively large distance between the second conditioner roll 422 and the wind-up roll 430 allows the copper foil to have a relatively large buffer space before entering the wind-up roll 430, thereby stabilizing the tension of the copper foil.
In an alternative embodiment, the winding device 400 further includes a frame 440, the driving mechanism 410 and the winding roller 430 are disposed on the frame 440, the first adjusting roller 421 and the second adjusting roller 422 are disposed on the mounting plate 480, the mounting plate 480 is slidably disposed on the frame 440, and the driving mechanism 410 is connected to the mounting plate 480 and can drive the mounting plate 480 to move. In this embodiment, the first adjustment roller 421 and the second adjustment roller 422 are disposed on the mounting plate 480, and the driving mechanism 410 can drive the mounting plate 480 to move, so as to drive the first adjustment roller 421 and the second adjustment roller 422 to move. Alternatively, the first regulating roller 421 and the second regulating roller 422 are rotatably provided on the mounting plate 480, so that friction between the copper foil and the first regulating roller 421 and the second regulating roller 422 can be reduced; the driving mechanism 410 may be a rack and pinion driving device, a screw nut driving device, an air cylinder, an electric cylinder, or the like; the mounting plate 480 and the frame 440 can be slidably matched with each other through sliding rails, sliding grooves and other structures.
In a further embodiment, the winding device 400 further includes a limiting arm 450, both sides of the frame 440 are provided with the limiting arm 450, a first end of the limiting arm 450 is in running fit with the frame 440, a second end of the limiting arm 450 is detachably connected with the frame 440, the limiting arm 450 can be matched with the frame 440 to form a rotating space 460, and both ends of the winding roller 430 can be respectively arranged in the rotating spaces 460 on both sides. In this embodiment, the first end of the limiting arm 450 is rotationally matched with the frame 440, the second end of the limiting arm 450 is detachably connected with the frame 440, under the condition that the second end of the limiting arm 450 is detached from the frame 440, one end of the wind-up roller 430 can be placed between the limiting arm 450 and the frame 440, then the limiting arm 450 is rotated and the second end of the limiting arm 450 is connected with the frame 440, at this time, the limiting arm 450 is matched with the frame 440 to form a rotating space 460, the wind-up roller 430 can rotate in the rotating space 460, and under the limiting of the frame 440 and the limiting arm 450, the wind-up roller 430 cannot be separated from the rotating space 460. It can be seen that, after the structure of this embodiment is adopted, the wind-up roller 430 can be detached from the rotating space 460 by detaching the second end of the limiting arm 450, so that the wind-up roller 430 can be replaced conveniently.
In an alternative embodiment, the two sides of the frame 440 are provided with the sliding ways 470, the sliding ways 470 are located at one side of the rotating space 460 away from the adjusting roller 420 and are connected with the inner wall at the bottom of the rotating space 460, and the second end of the limiting arm 450 is disposed towards the sliding ways 470.
