The application mainly relates to recovery processing equipment for coiled pole pieces. As shown in fig. 1, in an embodiment of the present application, the stripping and feeding mechanism 100 of the above scheme is applied to a pole piece recycling device, and is specifically configured to unwind a rolled pole piece 200 and then convey the rolled pole piece to a downstream pole piece recycling station in a straight shape.
Illustratively, the peel-feed mechanism 100 includes: a feeding module 10, a stripping module 20 and a traction module 30. The feeding module 10 is used for conveying the coiled pole piece 200 to the stripping station 23 according to a preset beat; the stripping module 20 is arranged downstream of the feeding module 10, the stripping module 20 comprises a rotary driving assembly 21 and a stripping piece 22, the rotary driving assembly 21 defines a stripping station 23, the rotary driving assembly 21 can drive the coiled pole piece 200 positioned in the stripping station 23 to rotate, and the stripping piece 22 can strip the head end of the coiled pole piece 200 from the main body to unwind the coiled pole piece 200; the traction module 30 is disposed downstream of the stripping module 20, and the traction module 30 is used for dragging the stripped pole piece to move to a downstream recovery station.
In summary, implementing the technical scheme of the embodiment has the following beneficial effects: during operation, the coiled pole piece 200 is put into the feeding module 10, and the feeding module 10 automatically and continuously conveys the coiled pole piece 200 to the stripping station 23 according to a preset beat; when the rolled pole piece 200 enters the stripping station 23, the rotary driving assembly 21 starts to drive the rolled pole piece 200 to rotate, and when the head end of the outermost layer of the rolled pole piece 200 contacts with the stripping piece 22, the head end of the pole piece of the rolled pole piece 200 is stripped and separated from the main body of the rolled pole piece 200 by the scraping action of the stripping piece 22, and the stripped and separated flattened pole piece enters the traction module 30 along with the further rotation of the rotary driving assembly 21 and automatically moves to the downstream recovery station under the traction driving of the traction module 30. When the rolled pole piece 200 positioned in the stripping station 23 finishes stripping and unwinding operation, the next rolled pole piece 200 can automatically and intermittently enter the stripping station 23 in time under the drive of the feeding module 10, the whole pole piece stripping and feeding process is compact in rhythm, the waiting intermittent of belt breakage is eliminated, the feeding efficiency and the pole piece recycling efficiency are high, manual intervention is not needed, time and labor are saved, and the labor cost is reduced.
The tip of the rolled pole piece 200 refers to a free end of the pole piece at the outermost layer of the rolled pole piece 200; the main body of the rolled pole piece 200, specifically, the rolled portion of the rolled pole piece 200 that has not been peeled off and unrolled by the peeling member 22.
In addition, the stripping and feeding mechanism 100 further includes a bracket and a housing, and the feeding module 10, the stripping module 20 and the traction module 30 are respectively mounted on the bracket. The outer cover is at least arranged outside the feeding module 10 to improve the safety and the aesthetic degree.
In some embodiments, the feed module 10 includes a feed power assembly drivingly connected to the feed drive wheel set, a feed drive wheel set, and a feed transfer assembly drivingly connected to the feed drive wheel set and capable of transferring the rolled pole piece 200. When the device works, the feeding power assembly outputs rotary power to drive the feeding transmission wheel set to rotate, so that the feeding transmission assembly can be driven to rotate, and finally the feeding transmission assembly drives the coiled pole piece 200 to move towards the stripping station 23 by means of friction force.
Specifically, in the above embodiment, the feeding power assembly includes the motor 11, the feeding transmission wheel set includes the first driving wheel 12 and the second driving wheel 13, the feeding transmission assembly includes the conveyer belt 14 and a plurality of baffles 15, the motor 11 is in driving connection with the first driving wheel 12 and/or the second driving wheel 13, the conveyer belt 14 is wound around the outside of the first driving wheel 12 and the second driving wheel 13, a plurality of baffles 15 are arranged on the outer peripheral surface of the conveyer belt 14 at intervals along the rotation direction, and a stock bin 16 for temporarily storing the coiled pole piece 200 is formed between any two adjacent baffles 15.
As the motor 11 drives the first driving wheel 12 and/or the second driving wheel 13 to rotate, the conveyor belt 14 can synchronously drive the partition plate 15 to rotate, and the partition plate 15 pushes the coiled pole piece 200 to move towards the stripping station 23, so that the moving reliability of the coiled pole piece 200 is improved. And because each rolled pole piece 200 is independently stored in the respective stock bin 16, the situation that two or even more rolled pole pieces 200 are fed at a time can be avoided, and the normal operation of stripping the subsequent pole pieces is influenced.
In addition, it should be noted that, by setting the rotation speed of the rotation driving assembly 21 and knowing the length of the single rolled pole piece 200, the time period for the single rolled pole piece 200 to complete the pole piece peeling can be accurately calculated. In this way, the conveying speed of the feeding module 10 can be adaptively set, that is, when the previous rolled pole piece 200 finishes pole piece stripping, the next rolled pole piece 200 can be just conveyed into the stripping station 23.
It should be noted that, the direction in which the rotary driving assembly 21 drives the rolled pole piece 200 to rotate should be such that the end of the outermost layer of the rolled pole piece 200 rotates toward the stripping member 22, that is, the direction in which the rotary driving assembly 21 drives the winding shaft of the rolled pole piece 200 to rotate should be opposite to the direction in which the winding shaft rotates when the rolled pole piece 200 is wound, so that the stripping member 22 can be ensured to successfully strip the end of the rolled pole piece 200 from the main body.
In some embodiments, the rotation driving assembly 21 includes an active rotation unit 211 and at least two passive rotation units 212, where the active rotation unit 211 and the at least two passive rotation units 212 are arranged at intervals along the circumferential direction and enclose a stripping station 23, a feed inlet of the stripping station 23 is opposite to the feeding module 10, and the stripping member 22 is disposed on the active rotation unit 211 or any passive rotation unit 212.
For example, a schematic of one active rotation unit 211 and two passive rotation units 212 is shown in this embodiment. The two passive rotating units 212 are separated from each other on both sides of the active rotating unit 211, and the three form a triangular support structure so as to stably accommodate the rolled pole piece 200 loaded into the stripping station 23.
During stripping operation, the active rotating unit 211 outputs rotating power to drive the rolled pole piece 200 to rotate in a preset direction, and meanwhile, the two passive rotating units 212 synchronously rotate along with the rolled pole piece 200 under the action of friction force, so that the effect of stably supporting the rolled pole piece 200 to rotate stably is achieved.
Of course, it should be noted that, in other embodiments, the number and arrangement of the active rotation units 211 and the passive rotation units 212 may also be changed in other ways, so long as the purpose of smoothly driving the rolled pole piece 200 to rotate can be achieved.
Alternatively, as an alternative to the above-described embodiment, the rotary drive assembly 21 includes a plurality of active rotary units 211. For example, three active rotation units 211 are provided in the present embodiment. The plurality of active rotation units 211 are arranged at intervals along the circumferential direction and enclose a stripping station 23, a feed inlet of the stripping station 23 is opposite to the feeding module 10, and the stripping piece 22 is arranged on any one of the active rotation units 211. The difference from the above embodiment is that the three active rotation units 211 can simultaneously output the same rotation driving force, so that the rolled pole piece 200 can be driven to rotate better, the stripping speed of the rolled pole piece 200 is improved, and the stripping operation of the rolled pole piece 200 with larger size can be performed.
On the basis of the above embodiment, the active rotation unit 211 includes a driving source, a driving roller 211a, and a first telescopic driver 211b, the driving source is in driving connection with the driving roller 211a, and the first telescopic driver 211b is in driving connection with the driving source or the driving roller 211a to drive the driving roller 211a to approach or separate from the peeling station 23. Further, the passive rotation unit 212 includes a passive roller 212a and a second telescopic driver 212b, and the second telescopic driver 212b is in driving connection with the passive roller 212a to drive the passive roller 212a to approach or separate from the stripping station 23.
In the initial state, the first telescopic driver 211b and the second telescopic driver 212b drive the driving roller 211a and the driven roller 212a to retreat in a direction away from the stripping station 23, so as to enlarge a feed inlet of the stripping station 23, and the rolled pole piece 200 is easier to enter the stripping station 23. Thereafter, the first and second telescoping drivers 211b and 212b drive the drive roller 211a and the driven roller 212a to extend toward the stripping station 23, thereby pinching the rolled pole piece 200 to drive the rolled pole piece 200 to rotate effectively. And in the process that the pole piece is continuously stripped, the diameter of the coiled pole piece 200 is gradually reduced, and the first telescopic driver 211b and the second telescopic driver 212b continuously push the driving roller 211a and the driven roller 212a to be close, so that the coiled pole piece 200 is always clamped, the coiled pole piece 200 is continuously driven to rotate, and the pole piece can be stripped and unfolded completely.
Alternatively, the first telescopic driver 211b and the second telescopic driver 212b may be, but not limited to, any one of an electric push rod, an air cylinder, an oil cylinder, and the like, and specifically may be selected according to actual needs.
To more effectively peel the leading end of rolled pole piece 200 from the body, stripper member 22 is provided with a pointed end that is disposed toward stripping station 23. The tip has a better scraping action.
Preferably, the stripping members 22 are provided in two and spaced apart from each other, with a stripping channel formed between the two stripping members 22. When the device works, the stripping piece 22 positioned above is mainly used for scraping and separating the head end of the coiled pole piece 200 from the main body, and the stripping piece 22 positioned below can timely bear the stripped unfolding pole piece, so that the unfolding pole piece can be accurately guided to the traction module 30.
Furthermore, on the basis of any of the above embodiments, the traction module 30 includes a first traction wheel set 31 and a second traction wheel set 32, and the first traction wheel set 31 and the second traction wheel set 32 are longitudinally spaced apart; wherein at least one of the first traction wheel set 31 and the second traction wheel set 32 is capable of actively rotating. The stripped pole piece head end enters a gap between the first traction wheel set 31 and the second traction wheel set 32, and then the first traction wheel set 31 and/or the second traction wheel set 32 rotate, so that the pole piece can be continuously conveyed to a downstream recycling station under the action of friction force. The pole piece traction mode can be matched with the stripping speed of the pole piece from the coiled pole piece 200, and prevents the pole piece from stacking and wrinkling, and influences the recovery efficiency and quality of the pole piece.
Further, in still other embodiments, the stripping and loading mechanism 100 further includes a guide rail 40, and the guide rail 40 is disposed between the stripping station 23 and the traction module 30. The guide rail 40 can accurately and flatly guide the stripped pole piece to the traction module 30 and effectively enter a gap formed by the first traction wheel set 31 and the second traction wheel set 32 so as to ensure that the pole piece is smoothly pulled to move downstream. For example, in the present embodiment, since the stripping module 20 is located obliquely above the traction module 30, the rail surface of the guide rail 40 is designed into a concave arc shape, and the higher end of the rail surface is connected to the stripping module 20, and the lower end is connected to the traction module 30.
In summary, the present application further provides a pole piece recycling device, which includes the stripping and feeding mechanism 100 according to any one of the embodiments.
