In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0037] As Figure 1 shown, this embodiment provides a pole piece processing device, including a rolling mechanism, a winding mechanism, and a roller mechanism. The rolling mechanism is used to extrude and flatten the pole piece 100, the winding mechanism is used to wind the rolled pole piece 100, and the roller mechanism can be arranged between the rolling mechanism and the winding mechanism to tension the pole piece 100 to prevent the pole piece 100 from wrinkling.
[0038] In some embodiments, the rolling mechanism includes two relatively and rotatably arranged pressing rollers. The axes of the two pressing rollers are parallel, and a gap is reserved between the outer peripheral surfaces of the two pressing rollers for the pole piece 100 to pass through, so as to extrude and flatten the pole piece 100 through the pressing rollers.
[0039] Optionally, the two pressing rollers rotate towards each other to drive the pole piece 100 to convey while extruding the pole piece 100.
[0040] In some embodiments, the winding mechanism includes a winding roller and a winding drive assembly. The winding roller is in transmission connection with the winding drive assembly and rotates under the driving action of the winding drive assembly, so as to wind the pole piece 100 on the outer peripheral surface of the winding roller.
[0041] In some embodiments, a plurality of roller passing mechanisms are provided. The plurality of roller passing mechanisms are arranged at intervals along the extending direction of the pole piece 100 to improve the uniformity of the tension degree of the pole piece 100, thereby avoiding wrinkling of the pole piece 100.
[0042] Combined Figure 1 with Figure 2 As shown, in some embodiments, the roller passing mechanism includes a frame 10, a roller 20 and a position adjustment assembly 30. Both axial ends of the roller 20 are connected to the frame 10 through the position adjustment assembly 30, so that the roller 20 can adaptively adjust its position in the first direction and the second direction according to the tension condition of the pole piece 100, automatically adjust the tension degree of the pole piece 100, without manual adjustment, which can avoid the problem of reduced yield caused by untimely response, and is beneficial to solving the problem of high cost caused by manual wrinkle removal. Wherein, in a plane perpendicular to the axis of the roller 20, the first direction and the second direction are two mutually perpendicular directions in this plane. That is to say, both the first direction and the second direction are parallel to the plane perpendicular to the axis of the roller 20, and the first direction and the second direction are perpendicular.
[0043] Specifically, the position adjustment assembly 30 includes a fixing member 31, a first elastic structure 32 and a second elastic structure 33. The fixing member 31 is rotatably connected to the roller 20. The first elastic structure 32 is elastically connected to the fixing member 31. The first elastic structure 32 is used to apply an elastic force along the first direction to the fixing member 31, so that the fixing member 31 moves adaptively along the first direction; the second elastic structure 33 is arranged on the frame 10 and is elastically connected to the first elastic structure 32. The second elastic structure 33 is used to apply an elastic force along the second direction to the first elastic structure 32, so that the first elastic structure 32 moves adaptively along the second direction.
[0044] Under the action of the pole piece 100, the first elastic structure 32 and the second elastic structure 33, when the force on the roller 20 reaches balance, the position of the fixing member 31 remains unchanged, and the first elastic structure 32 and the second elastic structure 33 reach balance. When the balance of the roller passing mechanism is broken, the forces on the roller 20 in the first direction and / or the second direction are unbalanced, and the roller 20 will have a tendency to move in the first direction and / or the second direction. The elastic acting forces of the first elastic structure 32 and / or the second elastic structure 33 on the roller 20 will be adaptively adjusted, and the position of the roller 20 will move correspondingly to reach a new balance to ensure uniform force on the pole piece 100.
[0045] For the convenience of understanding, an example is given where the electrode sheet 100 passes under the roller 20, the first direction is the vertical direction, and the second direction is the left - right direction. When the tension of the electrode sheet 100 changes, causing the force of the pressing roller in the vertical direction to lose balance, the roller 20 will move in the vertical direction, causing the elastic forces of the first elastic structure 32 on the fixing member 31 in the downward and upward vertical directions to change. One of the downward and upward vertical elastic forces increases, and the other decreases, thereby adjusting the force of the first elastic structure 32 on the fixing member 31 in the vertical direction, so that the force on the roller 20 in the vertical direction reaches a new balance to adjust the tension of the electrode sheet 100.
[0046] Exemplarily, when the tension of the electrode sheet 100 changes, causing the force of the pressing roller in the left - right direction to lose balance, the roller 20 will move in the left - right direction, causing the elastic forces of the second elastic structure 33 on the fixing member 31 in the left and right directions to change. One of the left and right elastic forces increases, and the other decreases, thereby adjusting the force of the second elastic structure 33 on the fixing member 31 in the left - right direction, so that the force on the roller 20 in the left - right direction reaches a new balance to adjust the tension of the electrode sheet 100.
[0047] Combined with Figure 2 and Figure 3 As shown, the first elastic structure 32 includes two first mounting members 321 and a plurality of first elastic members 322. The two first mounting members 321 are spaced apart along the first direction (such as the X direction as shown in Figure 2 and Figure 3 ), and are respectively located on both sides of the fixing member 31. A first elastic member 322 is connected between each first mounting member 321 and the fixing member 31. The elastic forces exerted by the first elastic members 322 on both sides on the fixing member 31 are in opposite directions, so that after the fixing member 31 receives a force in the first direction, the first elastic members 322 on both sides of the fixing member 31 can adaptively deform to adjust the position of the fixing member 31 and the elastic force received, so that the fixing member 31 reaches a new balance in the first direction, and then the roller 20 connected to the fixing member 31 adjusts its position accordingly, so that the roller 20 adaptively adjusts the tension of the electrode sheet 100.
[0048] In some embodiments, the first elastic members 322 on both sides are both springs. The structure of the spring is simple, the cost is low, and the provided elastic connection effect is stable.
[0049] In some embodiments, the first elastic member 322 can be a compression spring or a tension spring. Preferably, the first elastic member 322 is a compression spring, so that the arrangement of the first mounting member 321 and the fixing member 31 is more compact, which is beneficial to reducing the size of the roller mechanism.
[0050] In some embodiments, to make the first elastic structure 32 more stable, a first guide rod 323 is connected to the fixing member 31. The first guide rod 323 slidably penetrates through the first mounting member 321 to provide guiding for the movement of the fixing member 31 in the first direction.
[0051] As Figure 4 shown, a first guide rod 323 is provided on each side of the fixing member 31 facing each first mounting member 321. A first guide hole is correspondingly provided on the first mounting member 321, and the first guide rod 323 slidably penetrates through the first guide hole. When the fixing member 31 drives the over-roller 20 to perform adaptive adjustment in the first direction, the fixing member 31 drives the first guide rod 323 to move relative to the first mounting member 321, causing the fixing member 31 to approach one side of the first mounting member 321 and move away from the first mounting member 321 on the other side, and the first guide rod 323 slides in the corresponding first guide hole.
[0052] Optionally, the parameters of the first elastic members 322 on both sides of the fixing member 31 can be the same.
[0053] In some embodiments, the first elastic member 322 can be sleeved on the first guide rod 323 on the corresponding side to guide the first elastic member 322 through the first guide rod 323, avoid the deviation of the elastic force direction caused by the bending of the first elastic member 322, and at the same time, make the structure of the first elastic structure 32 more compact.
[0054] In some embodiments, as Figure 4 shown, to reduce the friction between the first guide rod 323 and the first guide hole, a first linear bearing 324 is provided in the first guide hole, and the first guide rod 323 penetrates through the first linear bearing 324 to reduce the friction.
[0055] In some embodiments, the second elastic structure 33 includes two second mounting members 331 and a plurality of second elastic members 332. The two second mounting members 331 are spaced apart along the second direction (such as Figure 2 and Figure 3 shown in the Y direction). The fixing member 31 and the first elastic structure 32 are both located between the two second mounting members 331. A second elastic member 332 is connected between each second mounting member 331 and the first elastic structure 32. The elastic forces exerted by the second elastic members 332 on both sides on the first elastic structure 32 are in opposite directions. After the first elastic structure 32 is subjected to a force in the second direction, the second elastic members 332 on both sides of the first elastic structure 32 can adaptively deform to drive the fixing member 31 to move in the second direction, so that the fixing member 31 reaches a new balance in the second direction, and further enables the over-roller 20 to adaptively adjust the tension of the pole piece 100.
[0056] Optionally, the second elastic member 332 can be elastically connected to the first mounting member 321 and the second mounting member 331 to drive the fixing member 31 to move in the second direction through the first mounting member 321.
[0057] In some embodiments, the second elastic members 332 on both sides are springs. Springs have a simple structure, low cost, and provide a stable elastic connection effect.
[0058] In some embodiments, the second elastic member 332 can be a compression spring or a tension spring. Preferably, the second elastic member 332 is a compression spring, so that the arrangement of the second mounting member 331 and the first mounting member 321 is more compact, which is beneficial to reducing the size of the roller passing mechanism.
[0059] In some embodiments, at least two second elastic members 332 can be provided between the second mounting member 331 and each first mounting member 321, so that the elastic force provided by the second elastic structure 33 acting on the first mounting member 321 is more evenly distributed.
[0060] In some embodiments, in order to make the second elastic structure 33 more stable, a second guide rod 333 is connected to the first mounting member 321. The second guide rod 333 slidably passes through the second mounting member 331 to provide a guiding function for the movement of the first mounting member 321 in the second direction.
[0061] As Figure 5 shown, the second guide rod 333 is fixedly connected to the frame 10. The second guide rod 333 penetrates the first mounting member 321 in the second direction. After the two ends of the second guide rod 333 extending out of the first mounting member 321 are slidably engaged with the second mounting member 331 respectively, they are fixedly connected to the frame 10. This setting enables the first mounting member 321 to slide along the second guide rod 333, so as to drive the roller 20 to perform adaptive adjustment in the second direction through the fixing member 31.
[0062] Optionally, second guide holes are correspondingly provided on both the second mounting member 331 and the first mounting member 321. The middle part of the second guide rod 333 slidably passes through the second guide hole on the first mounting member 321, and the two ends of the second guide rod 333 extending out of the first mounting member 321 slidably pass through the corresponding second guide holes on the second mounting member 331. When the first mounting member 321 drives the roller 20 to perform adaptive adjustment in the second direction through the fixing member 31, the first mounting member 321 drives the first guide rod 323 to move in the second direction, so that the first mounting member 321 approaches one side of the second mounting member 331 and moves away from the second mounting member 331 on the other side, and the second guide rod 333 slidably cooperates with the corresponding second guide hole.
[0063] In some embodiments, the second guide rod 333 may be fixedly connected to the first mounting member 321, and the second guide rod 333 is slidably engaged with the second mounting member 331. When the first mounting member 321 drives the over-roller 20 to perform adaptive adjustment in the second direction through the fixing member 31, the second guide rod 333 moves relative to the frame 10 and the second mounting member 331 together with the first mounting member 321.
[0064] Optionally, the second guide rod 333 may be fixedly inserted through the first mounting member 321, such that both ends of the second guide rod 333 are slidably engaged with the corresponding second mounting members 331 respectively. Alternatively, a second guide rod 333 is fixedly connected to one side of each first mounting member 321 facing the second mounting member 331.
[0065] Optionally, the parameters of the second elastic members 332 located on both sides of the first mounting member 321 may be the same.
[0066] In some embodiments, the second elastic member 332 may be sleeved on the second guide rod 333 on the corresponding side to guide the second elastic member 332 through the second guide rod 333, avoiding the deviation of the elastic force direction caused by the bending of the second elastic member 332. Meanwhile, the structure of the second elastic structure 33 can also be made more compact.
[0067] In some embodiments, as Figure 5 shown, in order to reduce the friction between the second guide rod 333 and the second guide hole, second linear bearings 334 are provided in the second guide holes on the first mounting member 321 and the second mounting member 331, and the second guide rod 333 is inserted through the second linear bearings 334 to reduce the friction.
[0068] In order to adjust the response sensitivity of the second elastic structure 33, in some embodiments, the mounting position of the second mounting member 331 on the frame 10 is adjustable in the second direction, so as to be able to adjust the distance between the two second mounting members 331, achieve the adjustment of the deformation amount of the second elastic member 332, and further be able to adjust the sensitivity of the adaptive movement of the over-roller 20 in the second direction.
[0069] Specifically, an adjustment structure is provided on the frame 10, and the adjustment structure is used to adjust the position of the second mounting member 331 in the second direction. Among them, the adjustment structure includes a detachable adjustment member 11 and a fastening member. The adjustment member extends in the second direction, and the fastening member is connected to the second mounting member 331.
[0070] In some embodiments, the adjustment member 11 is a sliding hole provided on the frame 10 and extending in the second direction. The fastening member is fitted in the sliding hole and can slide in the sliding hole to adjust the position of the fastening member. After passing through the sliding hole, the fastening member is fixed to the second mounting member 331, thereby fixing the second mounting member 331 to the frame 10.
[0071] Optionally, the fastener may be a screw. After the screw cooperates with the second mounting member 331, the head of the screw is located on the side of the rack 10 away from the second mounting member 331. Loosening the screw can adjust the position of the second mounting member 331 on the rack 10 along the second direction, and tightening the screw can fix the second mounting member 331 to the rack 10.
[0072] In other embodiments, the adjustment member 11 may be a slide rail or a slide groove, and the fastener slidably cooperates with the slide rail or the slide groove and can be connected to the rack 10 , thereby adjusting the installation position of the second mounting member 331 on the rack 10 .
[0073] In other embodiments, the adjustment member 11 may include a plurality of connection holes arranged along the second direction, and the fastener may be engaged with any of the connection holes and then connected to the second mounting member 331 , and the installation position of the second mounting member 331 on the rack 10 may also be adjusted.
[0074] In order to improve the stability of the position adjustment assembly 30 on the frame 10, at least one limiting assembly is provided on the frame 10, and the limiting assembly includes two limiting plates 12 spaced apart along the second direction, the position adjustment assembly 30 is located between the two limiting plates 12, and the end of the second guide rod 333 is passed through the limiting plate 12. By providing the limiting assembly, the position adjustment assembly 30 can be roughly positioned, and the installation is convenient; by the cooperation between the limiting plate 12 and the second guide rod 333, the second guide rod 333 can be slidably guided to prevent the position adjustment assembly 30 from falling off the frame 10.
[0075] In some embodiments, the fixing member 31 is embedded with a bearing, and the end of the roller 20 cooperates with the bearing to reduce the resistance encountered by the roller 20 when rotating.
[0076] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
