[0002] The battery pole piece is an important component in the battery, mainly responsible for the conduction of current and the catalytic effect of chemical reaction. In the battery production process, the pole piece needs to be rolled to extend it. However, in the actual rolling operation, the pole piece is affected by factors such as different speeds of winding and unwinding, asynchronous tension, and the like, which can easily cause the risk of belt breakage during the rolling process.
[0003] In the prior art, the shaking and intermittent pulling caused by factors such as different speeds and mismatched tension before and after the pole piece rolling are usually absorbed by adding a partition rubber roller and a floating swing roller before and after the pole piece rolling device. However, the overall structure is complex, and the partition rubber roller is prone to wear, so it needs to be replaced regularly, greatly increasing the material cost and maintenance cost. SUMMARY

[0014] In the present implementation, the elastic stroke of the elastic assembly is adjusted by adjusting the position of the stroke adjusting assembly relative to the buffer roller assembly.
[0015] In some implementations, the stroke adjusting assembly includes an adjusting locking member sleeved at both ends of the mounting seat and located in the extension direction of the elastic assembly.
[0016] In the present implementation, the adjusting locking member is sleeved on the mounting seat and abuts against one side of the elastic assembly away from the buffer roller assembly, and is locked in the vertical extension direction of the elastic assembly, thereby ensuring the reliability of the adjusting locking member.

[0037] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. The described embodiments are some embodiments of the present application, but not all the embodiments of the present application.
[0038] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.
[0039] Example 1:
[0040] Please refer to the accompanying drawings Figure 1 The accompanying drawings Figure 2 The pole piece 5 roll pressing device of the present application comprises a main roll mechanism 1 and a buffer roll mechanism 2.
[0041] Among them, please combine Figure 1 and Figure 2 , Figure 1 The structural relationship between the main roll mechanism 1 and the buffer roll mechanism 2 in the embodiments of the present application is shown, Figure 2 The specific structure of the buffer roll mechanism 2 in the embodiments of the present application is shown. Specifically, the main roll mechanism 1 is used for rolling the pole piece 5; the buffer roll mechanism 2 is respectively arranged upstream and downstream of the main roll mechanism 1, and is not in the same horizontal plane as the main roll mechanism 1. Among them, the buffer roll mechanism 2 comprises a mounting seat 21, an elastic assembly 22 and a buffer roll assembly 23, the elastic assembly 22 is connected to the mounting seat 21, and the buffer roll assembly 23 is connected to the elastic assembly 22; when the pole piece 5 is simultaneously arranged in the main roll mechanism 1 and the buffer roll mechanism 2, the A surface of the pole piece 5 abuts against the buffer roll assembly 23, and the B surface of the pole piece 5 abuts against the main roll mechanism 1.
[0042] In the embodiment, the main roller mechanism 1 is used for rolling the pole piece 5 to make it extend, and the buffer roller mechanism 2 is arranged upstream and downstream of the main roller mechanism 1 respectively to make the unwinding and winding speeds and the tension of the pole piece 5 before and after rolling consistent, thereby avoiding the problem that the pole piece 5 is shaken and intermittently pulled due to the inconsistent unwinding and winding speeds and the mismatched tension of the pole piece 5 when the pole piece 5 is rolled. Specifically, in the actual working process, the pole piece 5 passes through the main roller mechanism 1 and the buffer roller mechanism 2 at the same time. Since the buffer roller mechanism 2 and the main roller mechanism 1 are not in the same horizontal plane, the pole piece 5 is in a lifting state when it is conveyed, the A surface of the pole piece 5 abuts against the buffer roller assembly 23, and the B surface of the pole piece 5 abuts against the main roller mechanism 1. The buffer roller assembly 23 is tightly attached to the pole piece 5 under the tension of the elastic assembly 22 to provide resistance to the conveying of the pole piece 5, thereby buffering the conveying of the pole piece 5, absorbing the shaking and intermittent pulling caused by the inconsistent unwinding and winding speeds and the mismatched tension of the pole piece 5, avoiding the risk of belt breakage of the pole piece 5 in the rolling process, and further improving the production yield. Preferably, the main roller mechanism 1 is arranged obliquely above the buffer roller mechanism 2, thereby improving the reliability of the pole piece 5 rolling device.
[0043] The pole piece 5 rolling device described above is characterized in that the main roller mechanism 1 and the buffer roller mechanism 2 are not in the same horizontal plane, and the buffer roller mechanism 2 is arranged upstream and downstream of the main roller respectively. When the pole piece 5 is rolled, the pole piece 5 passes through the main roller mechanism 1 and the buffer roller mechanism 2 at the same time. The buffer roller assembly 23 is tightly attached to the pole piece 5 under the tension of the elastic assembly 22 to provide resistance to the conveying of the pole piece 5, thereby buffering the conveying of the pole piece 5, effectively absorbing the shaking and intermittent pulling of the pole piece 5 caused by the inconsistent unwinding and winding speeds and the mismatched tension of the pole piece 5, avoiding the risk of belt breakage of the pole piece 5 in the rolling process, and having a simple overall structure, occupying a small space, and reducing production costs while ensuring production yield.
[0044] In some preferred embodiments, the elastic assembly 22 includes a first elastic member 221 and a second elastic member 222, the first elastic member 221 and the second elastic member 222 are respectively sleeved on the mounting seat 21, and the buffer roller assembly 23 is sleeved on the mounting seat 21 and located between the first elastic member 221 and the second elastic member 222. The first elastic member 221, the buffer roller assembly 23 and the second elastic member 222 are vertically sleeved on the mounting seat 21 in sequence, and the mutual force of the first elastic member 221 and the second elastic member 222 is used to provide better resistance to the conveying of the pole piece 5. Specifically, when the pole piece 5 is conveyed, the buffer roller assembly 23 is subjected to the tension of the first elastic member 221 and the second elastic member 222 respectively, thereby providing better resistance to the conveying of the pole piece 5, and achieving the buffering effect.
[0045] In some other embodiments, only one elastic member is sleeved on the mounting seat 21 and abuts against the buffer roller assembly 23 to buffer the movement of the pole piece 5. For example, when the main roller mechanism 1 is arranged obliquely above the buffer roller mechanism 2, the elastic member is sleeved on the mounting seat 21 and located above the buffer roller assembly 23, and provides tension to the buffer roller assembly 23 downward, and the buffer roller assembly 23 is pushed upward by the pulling force of the movement of the pole piece 5, so as to provide a counteracting force to the tension of the elastic member, thereby providing resistance to the movement of the pole piece 5, and further buffering the movement of the pole piece 5.
[0046] Embodiment 2:
[0047] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the pole piece 5 rolling device of the utility model, please refer to the structure relationship between the mounting seat 21, the stroke adjusting assembly 24 and the elastic assembly 22 shown in the following figure. Figure 3 , Figure 3 The structure relationship between the mounting seat 21, the stroke adjusting assembly 24 and the elastic assembly 22 in the embodiment of the utility model is shown.
[0048] Among them, the stroke adjusting assembly 24 for adjusting the elastic stroke of the elastic assembly 22 is arranged between the mounting seat 21 and the elastic assembly 22.
[0049] In this embodiment, the position of the stroke adjusting assembly 24 relative to the buffer roller assembly 23 is adjusted, and then the elastic stroke of the elastic assembly 22 is adjusted. It can be understood that the shorter the elastic stroke of the elastic assembly 22 is, the stronger the elastic tension provided is, and the longer the elastic stroke of the elastic assembly 22 is, the weaker the elastic tension provided is, so that the elastic assembly 22 can be more adapted to the tension when the pole piece 5 moves by adjusting the elastic stroke of the elastic assembly 22. Preferably, the stroke adjusting assembly 24 is arranged on the side of the first elastic member 221 away from the buffer roller assembly 23 and the side of the second elastic member 222 away from the buffer roller.
[0050] In some preferred embodiments, the stroke adjusting assembly 24 includes an adjusting locking member 241 sleeved on both ends of the mounting seat 21 and located in the extension direction of the elastic assembly 22. The adjusting locking member 241 is sleeved on the mounting seat 21 and abuts against the side of the elastic assembly 22 away from the buffer roller assembly 23, and is locked in the vertical extension direction of the elastic assembly 22, thereby ensuring the reliability of the adjusting locking member 241, and the elastic stroke of the elastic assembly 22 can be adjusted by adjusting the position of the adjusting locking member 241 locked on the mounting seat 21.
[0051] In some preferred embodiments, the buffer roller mechanism 2 further comprises a limiting baffle 25 connected to the two end portions of the mounting seat 21 and located on the side of the adjusting locking member 241 away from the elastic assembly 22. The limiting baffle 25 prevents the adjusting locking member 241 from loosening, and makes the overall structure more compact, thereby improving the stability and reliability of the pole piece 5 roller pressing device.
[0052] In some preferred embodiments, please continue to refer to Figure 3 , Figure 3 The structural relationship between the floating seat 231 and the buffer roller 232 in the embodiment of the utility model is shown. Specifically, the buffer roller assembly 23 comprises the floating seat 231 and the buffer roller 232, the floating seat 231 is sleeved on the mounting seat 21 and abuts against the elastic assembly 22, and the buffer roller 232 is connected to the floating seat 231. When the pole piece 5 is pressed, the pole piece 5 abuts against the buffer roller 232, and since the buffer roller 232 is connected to the floating seat 231, and the floating seat 231 is sleeved on the mounting seat 21 and abuts against the elastic assembly 22, the floating seat 231 slightly floats under the elastic tension of the elastic assembly 22, thereby driving the buffer roller 232 to slightly float, so as to play a resistance role for the pole piece 5 before and after rolling, and absorb the pole piece 5 shaking and intermittent pulling caused by the inconsistent unwinding and winding speed and the mismatched tension of the pole piece 5, thereby realizing the buffering effect.
[0053] In some more preferred embodiments, two mounting seats 21 are oppositely provided, the two ends of the buffer roller 232 are respectively connected with the floating seats 231, and the buffer roller 232 is bridged on the mounting seat 21 through the floating seats 231. This ensures that the two sides of the pole piece 5 are parallel, and the overall structure is more stable, thereby improving the reliability of the pole piece 5 roller pressing device.

[0056] The main roller mechanism 1 comprises the first roller 11 and the second roller 12 oppositely arranged above and below, and the pole piece 5 is located between the first roller 11 and the second roller 12.
[0057] In this embodiment, the first roller 11 and the second roller 12 respectively press the pole piece 5 to make the pole piece 5 extend, thereby ensuring the reliability of the overall structure.
[0058] In some preferred embodiments, please continue to refer to Figure 4 ,Figure 4 The structure relationship of the main roller mechanism 1, the adjusting roller mechanism 3 and the buffer roller mechanism 2 in the embodiment of the utility model is shown. Specifically, the adjusting roller mechanism 3 is located between the main roller mechanism 1 and the buffer roller mechanism 2 and can move up and down relative to the main roller mechanism 1 and / or the buffer roller mechanism 2. By adjusting the position of the adjusting roller mechanism 3 relative to the main roller mechanism 1 and / or the buffer roller mechanism 2, the height of the roll-in and roll-out of the pole piece 5 is adjusted, and the pole piece 5 wrap angle at the roll-in and roll-out is further adjusted.
[0059] In some more preferred embodiments, the fixing frame 4 is further included, and the buffer roller mechanism 2, the adjusting roller mechanism 3 and the main roller mechanism 1 are arranged on the fixing frame 4 respectively. The fixing frame 4 supports the buffer roller mechanism 2, the adjusting roller mechanism 3 and the main roller mechanism 1 respectively, and makes the overall structure more compact, thereby improving the reliability of the pole piece 5 roll-in and roll-out device.
[0060] The pole piece 5 roll-in and roll-out device of the utility model, the main roller mechanism 1 and the buffer roller mechanism 2 are not in the same horizontal plane, and the buffer roller mechanism 2 is arranged at the upstream and downstream of the main roller respectively. When the pole piece 5 is rolled in, the pole piece 5 is arranged in the main roller mechanism 1 and the buffer roller mechanism 2 at the same time, and the buffer roller assembly 23 is tightly attached to the pole piece 5 under the tension of the elastic assembly 22 to provide resistance to the pole piece 5 roll-in, thereby playing a buffering role in the pole piece 5 roll-in, effectively absorbing the pole piece 5 shaking and intermittent pulling caused by the different speeds of the pole piece 5 unwinding and winding and the mismatch of the tension and other factors, avoiding the risk of the pole piece 5 breakage in the roll-in process, and the overall structure is simple, the occupied space is small, the production yield is ensured, and the production cost is reduced.
