Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments accompanying the present application are described in detail below with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Please refer to fig. 1 and fig. 2. Fig. 1 is a schematic structural diagram of an embodiment of the correction device 1 of the present application, and fig. 2 is a schematic diagram of a material tape 30.
In some embodiments, the correction device 1 comprises at least two transport rollers 13, an abutment roller 14. The two conveying rollers 13 are arranged in parallel and spaced apart. The transfer roller 13 is for pressing against a first side surface of the tape 30 and transferring the tape 30. The pressing roller 14 is parallel to the conveying rollers 13 and presses the second side surface of the material tape 30 between the two conveying rollers 13. The first side surface and the second side surface are respectively located on two opposite sides of the material belt 30, and the contact area between the pressing roller 14 and the material belt 30 is smaller than the contact area between the conveying roller 13 and the material belt 30. The pressing direction of the pressing roller 14 is opposite to the warping direction of the material tape 30.
In this embodiment, the material tape 30 is a pole piece material tape and is in a roll shape. The correction device 1 can neutralize the internal stress of the material belt 30 and improve the warping phenomenon of the material belt 30. The correction device 1 comprises two transport rollers 13, an abutment roller 14. The transport roller 13 and the pressing roller 14 have the same length and are both larger than the width of the material tape 30. As shown in fig. 2, the strip of material 30 has first and second opposing side surfaces. The two transfer rollers 13 press against the first side surface of the web 30. During the movement of the tape 30, the transfer roller 13 rotates, so that the tape 30 can be moved to the next process more easily. The pressing roller 14 is parallel to the conveying roller 13. In the process of neutralizing the internal stress of the material tape 30, the pressing roller 14 presses the second side surface of the material tape 30 between the two conveying rollers 13. When the abutting roller 14 and the conveying roller 13 abut against the material belt 30, the tension value of the material belt 30 is fixed. Since the contact area of the pressing roller 14 and the material tape 30 is smaller than the contact area of the conveying roller 13 and the material tape 30, the pressure applied to the material tape 30 by the pressing roller 14 is larger than the pressure applied to the material tape 30 by the conveying roller 13. The pressing direction of the pressing roller 14 is opposite to the warping direction of the material tape 30, so that the material tape 30 is bent reversely to a greater extent. After the strip of material 30 leaves the correction device 1, the stresses in the strip of material 30 cancel each other out and no longer buckle.
In some embodiments, the relative positions of the conveying roller 13 and the pressing roller 14 in the pressing direction are adjustable. Depending on the degree of the warpage of the material tape 30 and the kind of the material tape 30, the relative positions of the conveying roller 13 and the pressing roller 14 in the pressing direction may be changed, so that the warpage of the material tape 30 is better corrected.
In some embodiments, the correcting device 1 comprises a support 11, a moving seat 12 and a locking member 15. The movable base 12 is movably disposed on the support 11 along the pressing direction. The locking member 15 selectively locks the movable base 12 and the support 11. Wherein, one of transfer roller 13 and the pressure of propping pressing roller 14 sets up in support 11, and the other of transfer roller 13 and the pressure of propping pressing roller 14 sets up in removing seat 12. In some embodiments, the transport roller 13 is fixed to the support 11. The movable base 12 is slidably connected to the support 11 through a wire rail. The pressing roller 14 is disposed on the moving seat 12, and the relative position between the conveying roller 13 and the pressing roller 14 in the pressing direction is changed under the driving of the moving seat 12. Specifically, the moving seat 12 moves in the same direction as the radial direction of the pressing roller 14 and the pressing direction. In some embodiments, the correction device 1 slides with respect to the support 11 by means of a motor-driven mobile seat 12. In this embodiment, the movable seat 12 and the support 11 can slide only by motor drive, and the correcting device 1 can be provided without the locking member 15. The motor can directly adjust the distance and direction of movement of the movable base 12 and fix the relative position between the conveying roller 13 and the pressing roller 14. In some embodiments, the user can adjust the relative position between the conveying roller 13 and the pressing roller 14 manually. After the movable base 12 is moved to a predetermined position, the user can fix the movable base 12 to the support 11 by tightening the locking member 15, so that the movable base 12 can no longer move relative to the support 11. When it is necessary to adjust again the relative position between the transfer roller 13 and the abutment roller 14, the user releases the locking member 15 so that the movable base 12 and the support 11 can slide relatively. After the movable base 12 is moved to the predetermined position, the locking member 15 is tightened again. After the relative position of the movable base 12 and the support 11 is fixed, the relative position of the conveying roller 13 and the pressing roller 14 is also fixed. In the process of conveying the material belt 30, the conveying roller 13 presses against the pressing roller 14, so that the internal stress of the material belt 30 is neutralized, and the warping phenomenon after the material belt 30 is cut off is reduced.
In some embodiments, the pressing roller 14 is fixedly arranged on the support 11, and the conveying roller 13 is arranged on the moving seat 12. The relative position between the transfer roller 13 and the pressing roller 14 is changed by the moving base 12.
Please refer to fig. 3, 4 and 5. Fig. 3 is a schematic view of the correction device 1 according to an embodiment of the present application, which does not press the tape 30, fig. 4 is a schematic view of the correction device 1 according to another embodiment of the present application, which presses the tape 30, and fig. 5 is a schematic view of the correction device 1 according to another embodiment of the present application, which presses the tape 30.
In some embodiments, the gap between the two transfer rollers 13 is greater than the diameter of the abutment roller 14. The abutment roller 14 can pass through the gap of the two transfer rollers 13, optionally on one side of the two transfer rollers 13. As shown in fig. 3, a indicates a shape of the tape 30 when it is not warped. At this time, the conveying roller 13 directly presses against the material belt 30, and the pressing roller 14 is located on one side of the conveying roller 13 and does not press against the material belt 30. The web 30 passes between the transfer roller 13 and the pressing roller 14, and is transferred to the next process. Of course, the pressing roller 14 may be located on the other side of the conveying roller 13 as long as the conveying of the material tape 30 is not affected.
In some embodiments, as shown in fig. 4, B represents a shape of the tape 30 when warped, with a left-convex shape. When the pressing roller 14 does not press the material belt 30, the pressing roller 14 moves to the opposite left side of the material belt 30, the conveying roller 13 is located at the opposite right side of the material belt 30, and the material belt 30 and the pressing roller 14 are both located at the opposite left side of the conveying roller 13. When the material belt 30 is corrected, the moving seat 12 drives the pressing roller 14 to move in the direction opposite to the warping direction, that is, to move to the right side. The pressing roller 14 presses the material belt 30 and moves to the opposite right side of the conveying roller 13. The distance that the pressing roller 14 moves can be adjusted according to the actual situation. If the buckling deformation is large, the pressing roller 14 may move a further distance to neutralize the internal stress of the strip of material 30. The reason is that the tension value of the material belt 30 is fixed during the conveying process of the material belt 30, and the component force of the tension value in the pressing direction changes along with the change of the included angle between the material belt 30 and the pressing roller 14. When the distance that the pressing roller 14 presses the material belt 30 is farther, the included angle between the material belt 30 and the pressing roller 14 is smaller, the acting force of the pressing roller 14 on the material belt 30 in the pressing direction is larger, and the correction effect on the warping of the material belt 30 is better.
In some embodiments, C represents the shape of the strip of material 30 when warped, as shown in fig. 5, as it bulges to the right. When the abutting roller 14 does not abut against the material belt 30, the abutting roller 14 moves to the opposite right side of the material belt 30, the conveying roller 13 is located at the opposite left side of the material belt 30, and the material belt 30 and the abutting roller 14 are both located at the opposite right side of the conveying roller 13. When the material belt 30 is corrected, the moving seat 12 drives the pressing roller 14 to move in the direction opposite to the warping direction, that is, to the left. The pressing roller 14 presses the material belt 30 and moves to the opposite left side of the conveying roller 13. In this way, one correction device 1 can correct the material belt in two different warping directions.
In some embodiments, the pressing roller 14 is detachably provided to the support 11 or the moving base 12, and/or the conveying roller 13 is detachably provided to the support 11 or the moving base 12. In some embodiments, the pressing roller 14 is detachably disposed on the support 11, and the conveying roller 13 is detachably disposed on the moving base 12. In some embodiments, the pressing roller 14 is detachably disposed on the moving base 12, and the conveying roller 13 is detachably disposed on the support 11. In some embodiments, the pressing roller 14 is detachably disposed on the moving seat 12, and the conveying roller 13 is fixedly disposed on the support 11. In some embodiments, the pressing roller 14 is detachably disposed on the support 11, and the conveying roller 13 is fixedly disposed on the moving seat 12. The pressing roller 14 and the conveying roller 13 are detachably provided, and it is possible to facilitate the user to replace the pressing roller 14 and the conveying roller 13. For example, the pressing roller 14 and the conveying roller 13 having longer lengths are replaced, or the diameter of the pressing roller 14 and the diameter of the conveying roller 13 are changed to adapt to different tapes 30.
In some embodiments, the diameter of the abutment roller 14 is smaller than the diameter of the transfer roller 13, such that the contact area of the web 30 on the abutment roller 14 is smaller than the contact area of the web 30 on the transfer roller 13. The tension value of the material belt 30 is fixed, and the pressure of the pressing roller 14 on the material belt 30 is greater than the pressure of the conveying roller 13 on the material belt 30, so that the material belt 30 is bent in the direction opposite to the warping direction, and the internal stress of the material belt 30 is neutralized. The pressing roller 14 and the conveying roller 13 with different diameters are replaced, so that the material belt 30 can be extruded at different pressures, and the pressure requirements of different material belts 30 in warping correction are met.
In some embodiments, the corrective device 1 includes a wrap angle roller 16. The corner wrapping roller 16 is parallel to the transfer roller 13 and is configured to press the tape 30 beyond the two transfer rollers 13 to form a predetermined angle of wrap on the transfer roller 13. Specifically, the wrap angle roller 16 can adjust the wrap angle between the material belt 30 and the conveying roller 13 according to the type and thickness of the material belt 30. The wrap angle refers to the central angle subtended by the arc of contact of the strip of material 30 with the roll surface. If the wrap angle is too small, or if the wrap angle is too large, the correction effect of the correction device 1 is affected.
In one embodiment, the wrap angle roller 16 has the same diameter as the transfer roller 13. The number of the cornerite rollers 16 is two, and the cornerite roller 16a causes the tape 30 to contact the conveying roller 13c at a predetermined angle and direction. By adjusting the position of the corner wrapping roller 16a, the wrap angle of the tape 30 on the conveying roller 13c can be changed, and the contact area of the tape 30 and the conveying roller 13c is always kept constant. The wrap angle roller 16b causes the strip of material 30 to exit the transport roller 13a at a predetermined angle and direction. By adjusting the position of the corner wrapping roller 16b, the wrap angle of the tape 30 on the conveying roller 13a can be changed, and the contact area of the tape 30 and the conveying roller 13a is always kept constant.
In some embodiments, the number of the conveying rollers 13 is at least three, and the three conveying rollers 13 are parallel and arranged at intervals in a direction intersecting the pressing direction. The number of the pressing rollers 14 is at least two, the two pressing rollers 14 are parallel and are arranged at intervals along the direction intersecting with the pressing direction, and each pressing roller 14 is arranged corresponding to the gap between the two adjacent conveying rollers 13. The user can select a direction intersecting the pressing direction according to actual conditions, and the conveying roller 13 and the pressing roller 14 are arranged at intervals. In some embodiments, the selected direction is different when the conveying roller 13 and the pressing roller 14 are arranged at intervals in a direction intersecting the pressing direction.
In some embodiments, the number of the conveying rollers 13 is three, and the number of the pressing rollers 14 is two. The three conveying rollers 13 are arranged in parallel and at intervals in a direction perpendicular to the pressing direction. The two abutting rollers 14 are parallel and arranged at intervals along the direction perpendicular to the abutting direction, and each abutting roller 14 is arranged corresponding to the gap between two adjacent conveying rollers 13.
In some embodiments, the number of the conveying rollers 13 is four, and the number of the pressing rollers 14 is three. The four conveying rollers 13 are parallel and arranged at intervals along a direction having an angle of 80 degrees with the pressing direction. The number of the pressing rollers 14 is three, the three pressing rollers 14 are parallel and are arranged at intervals along the direction perpendicular to the pressing direction, and each pressing roller 14 is arranged corresponding to the gap between two adjacent conveying rollers 13. When the correcting device 1 corrects the warping of the material belt 30, each abutting roller 14 abuts against the material belt 30 with different pressure intensity and passes through the gap between two adjacent conveying rollers 13.
In some embodiments, the number of the conveying rollers 13 is five, and the number of the pressing rollers 14 is four. The larger the number of the conveying rollers 13 and the pressing rollers 14 is, the more the material belt 30 can be repeatedly bent, and the better the correction effect of the warping of the material belt 30 is.
In some embodiments, a plurality of pressing rollers 14 are disposed on the same movable base 12. The pressing rollers 14 move synchronously when pressing the material belt 30, and the moving distance and direction are the same. In some embodiments, the support 11 is provided with a plurality of mobile seats 12, and the pressing rollers 14 are provided on different mobile seats 12. According to actual requirements, each movable seat 12 moves different distances, so that each pressing roller 14 acts on the material belt 30 with different pressures.
In some embodiments, the impression roller 14 is capable of generating heat, heating the strip of material 30 as it is pressed against the strip of material 30. The strip of material 30 is better able to bend at higher temperatures, neutralizing internal stresses and improving warpage.
In some embodiments, both the transfer roller 13 and the pressing roller 14 can generate heat, and the transfer roller 13 and the pressing roller 14 heat the tape 30 while pressing the tape 30.

The first cutting assembly 3 is disposed after the correction device 1 along the moving path of the material belt 30 and before the driving assembly 5, and is used for cutting the tab 31 on the material belt 30. A second cutting assembly 6 is disposed after the drive assembly 5 along the path of travel of the strip of material 30 for selectively cutting the strip of material 30 along its length.
In some embodiments, the material belt 30 passes through the unwinding assembly 2, the correcting device 1, the first cutting assembly 3, the driving assembly 5 and the second cutting assembly 6 in sequence under the driving of the driving assembly 5. The unwinding assembly 2 is used for unwinding the material belt 30. A plurality of rollers for conveying the tape 30 are further provided on the moving path of the tape 30. The tape 30 is moved along a predetermined path by the driving assembly 5. The drive assembly 5 may be a pair of rollers driven by a motor. As shown in fig. 7, the first cutting assembly 3 is used to cut tabs 31 from the strip of material 30. In some embodiments, the first cutting assembly 3 can cut other shapes into the strip of material 30, which can be set according to the needs of the user. As shown in FIG. 8, second cutting assembly 6 cuts strip material 30 along its length so that the cut strip material 30 meets a predetermined width. The size of the second cutting assembly 6 can be set according to the needs of the user.
In some embodiments, the flaking device includes the cleaning component 4, the rolling component 7. The cleaning assembly 4 is disposed behind the first cutting assembly 3 and in front of the driving assembly 5 along the moving path of the material belt 30, and is used for cleaning the tab 31. The winding component 7 is disposed behind the second cutting component 6 along the moving path of the material belt 30, and is used for winding the material belt 30 which is not cut by the second cutting component 6.
In some embodiments, there are two cleaning assemblies 4. The strip of material 30 has a coating on both sides. The strip material 30 is cut to form the tab 31 after passing through the first cutting assembly 3. The front and rear surfaces of the tab 31 are still coated, and the coating on the tab 31 affects the quality of the product, so that the coating on the tab 31 needs to be cleaned. The cleaning assembly 4a is used for cleaning the front surface of the tab 31, and the cleaning assembly 4b is used for cleaning the back surface of the tab 31. Of course, in some embodiments, only one cleaning assembly 4 may be provided, and the tab 31 may be cleaned on both sides. In order to facilitate threading of the new material strip 30, so that the new material strip 30 can move along a predetermined path under the driving of the driving assembly 5, the winding assembly 7 is disposed behind the second cutting assembly 6 along the moving path of the material strip 30. Specifically, when the original strip of material 30 is about to be depleted, a new strip of material 30 is connected to the original strip of material 30. The second cutting component 6 stops working, and the driving component 5 drives the original material belt 30 to move and is wound by the winding component 7. When the original strip of material 30 is taken up by the take-up assembly 7, the new strip of material 30 also reaches the second cutting assembly 6. The second cutting assembly 6 continues to operate to cut a new strip of material 30.
