Description

Electrode foil rolling system

Technical Field

The utility model belongs to the technical field of the electrode forming technique and specifically relates to an electrode forming rolling system.

Background

In the process of producing the electrode foil, the electrode foil needs to be subjected to hole forming, namely holes are prepared on the surface of the electrode foil through a corrosion process. In order to ensure that the electrode foil still maintains good tensile strength in a subsequent drawing or rolling process, a certain width of 'smooth edge' is left at the edge part of the electrode foil, and the corrosion of the middle part is always carried out in a whole surface.

After the etching process is finished, the electrode foil needs to be aligned and rolled. However, the winding effect of the electrode foil is poor, and the reason is that: along the width direction, the thicknesses of different areas of the electrode foil are obviously different, and the thickness of the area with the 'smooth edge' is mainly changed into that the thickness of the area without the 'smooth edge' is larger than that of other areas; in the coiling process, the edge of the electrode foil is bound to generate edge warping phenomenon under the action of tension. And the edge warping phenomenon can be caused by the uneven heating of the aluminum foil in the annealing process. In the present situation, the foil rolls are intentionally misaligned to avoid losses due to edge lifting of the aluminum foil, but the misaligned foil rolls are not conducive to subsequent processes. In order to obtain a "clean" foil roll, and to reduce losses due to edge lifting. When the foil is continuously rolled, two production line workers are matched with two sides of the rolling roller, and the production line workers press and contact the edge parts of two sides of the rolled electrode foil by using a special rolling tool so as to flatten the raised edges of the areas. However, in the winding process, two line workers are required to keep the hand-pressing state all the time and maintain the state until the electrode foil winding process is finished, so that the labor intensity of the line workers is high and fatigue is easy to occur. With the advance of the winding process, the winding thickness of the electrode foil is continuously increased, so that production line workers are required to adjust wrist force in real time (if the pressure is insufficient, the tightness and the uniformity of the wound electrode foil are poor, and if the pressure is too high, the electrode foil is easily pressed or scratched by a special rolling tool), the implementation difficulty is extremely high, and the operation experience requirement is extremely high. Thus, a skilled person is urgently needed to solve the above problems.

Detailed Description

In the description of the present invention, it is to be understood that the terms "front", "back", "upper", "lower", "left", "right", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the indicated unit or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

The following detailed description is made with reference to specific examples, and fig. 1 shows a schematic structural diagram of a first embodiment of the middle electrode foil winding system of the present invention, which is mainly composed of a winding unit 1 and a blank pressing unit 2. The winding unit 1 comprises a support frame 11, a winding drum 12 and a first speed reduction motor 13. The support frame 11 is fixed on the floor of the workshop by anchor bolts and is used for supporting and bearing the reel 12. The first reduction motor 13 is borne by the supporting frame 11 for driving the reel 12 to perform a circumferential rotary motion about its own central axis, during which the electrode foils are wound in layers. The edge pressing unit 2 and the winding unit 1 are matched for application and cooperate with each other to realize the compact winding of the electrode foil. The edge pressing unit 2 comprises a left edge pressing sub-unit 21 and a right edge pressing sub-unit 22. The left and right edge pressing subunits 21, 22 are symmetrically disposed along the left-right direction, and apply pressure to the left and right edges of the pre-rolled electrode foil in a one-to-one correspondence.

In the actual winding process of the electrode foil, the left edge pressing subunit 21 and the right edge pressing subunit 22 independently act to respectively realize the pressing of the left edge and the right edge of the pre-wound electrode foil, thereby effectively avoiding the influence of the local edge warping and the inconsistent thickness of the electrode foil on the winding process and ensuring that the electrode foil is wound neatly and compactly.

What is more important is that the production line workers can be relieved from the heavy pressing operation work by the field application of the left edge-placing subunit 21 and the right edge-placing subunit 23, the requirements on the operation experience are relaxed, and good bedding is further made for the reduction of the production and manufacturing cost of the electrode foil.

As a further refinement of the structure of the electrode foil winding system, as shown in fig. 1, the left edge pressing subunit 21 is mainly composed of a left base 211, a left mounting base 212, a left pressing roller 213, a left linear driving unit 214, and so on. Wherein, the left pressing roller 213 can be used to press directly against the left edge of the pre-rolled electrode foil, and can be freely and rotatably hinged with the left mounting seat 212. The left linear driving unit 214 is supported by the left base 211, and includes a first left pneumatic cylinder 2141 and a second left pneumatic cylinder 2142 which are arranged side by side in the left-right direction and drive the left mounting base 212 in cooperation with each other. The right edge pressing subunit 22 is mainly composed of a right base 221, a right mounting seat 222, a right pressing roller 223, a right linear driving unit 224, and the like. Wherein the right pressing roller 223 can be used to press directly against the right edge of the pre-rolled electrode foil and can be freely rotatably hinged with the right mounting seat 221. The right linear driving unit 224 is supported by the right base 221, and includes a first right pneumatic cylinder 2241 and a second right pneumatic cylinder 2242 arranged in parallel in the left-right direction to drive the right mount 222 in cooperation. Along with the increase of the number of the electrode foil winding layers, the first left pneumatic cylinder 2141 and the second left pneumatic cylinder 2142 cooperate to drive the left pressure roller 213 to perform adaptive upward movement, and at the same time, the first right pneumatic cylinder 2241 and the second right pneumatic cylinder 2242 cooperate to drive the right pressure roller 223 to perform adaptive upward movement, so as to ensure that the left and right edges of the electrode foil to be wound are constantly pressed by the left pressure roller 213 and the right pressure roller 223, which is favorable for ensuring that the wound electrode foil has better compactness.

As is also apparent from the illustration in fig. 1, the left and right

pressing rollers

213 and 223 are each preferably a rubber pressing roller for applying elastic pressing force toward the left and right side edges of the pre-wound electrode foil, respectively. By adopting the technical scheme for setting, on one hand, the 'warped edge' in the winding process is further ensured to be stably and effectively eliminated; on the other hand, the phenomenon that the electrode foil is damaged due to the action of rigid extrusion force is avoided.

Fig. 2 shows a schematic structural diagram of a second embodiment of the middle electrode foil winding system of the present invention, which is different from the first embodiment in that: a second power part 23 is additionally provided. The left edge placing and pressing subunit 21 and the left edge placing and pressing subunit 21 can perform displacement movement in the opposite direction or in the opposite direction under the action of the driving force of the second power part 23 so as to adapt to electrode foils with different widths, and therefore the application range of the electrode foil winding system is effectively expanded. The second power unit 23 is composed of a left power sub-unit 231 and a right power sub-unit 232. The left power sub-section 231 and the right power sub-section 232 move independently to drive the left base 211 and the right base 221 to perform directional displacement motion along the left-right direction. The left power sub-section 231 and the right power sub-section 232 are preferably linear motors having extremely high operation response speed and extremely high displacement accuracy. When the rolling operation of the electrode foil with the relatively small/large width dimension is performed, the left power sub-section 231 and the right power sub-section 232 are simultaneously activated to respectively drive the left binder sub-unit 21 and the left binder sub-unit 21 to perform the opposite/reverse displacement motion, so as to ensure that the left pressure roller 213 and the right pressure roller 223 are stably pressed against the left and right side edges of the electrode foil to be rolled.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
