Description

Technical Field

[0001] The utility model belongs to the technical field of battery production, and in particular relates to a roller mechanism for preventing a tab from being folded. Background Art

[0002] At present, in the production process of battery cores, the pole pieces' ears often have warped corners or crescents due to poor stretching or slight pulling of the ear residue during die-cutting. Then, when the pole pieces pass through the winding rollers with small diameter and large curvature, the ears are easily folded or wrinkled at the rollers. In severe cases, the ears may even rupture and cause damage to the pole pieces, thus rendering the core scrapped and increasing production costs.

[0003] In order to solve the above problem, a smoothing mechanism is usually set at the roller to smooth the pole ear of the pole piece to prevent the pole piece from being folded. In the prior art, most smoothing mechanisms use a smoothing plate to smooth the pole ear. However, when the smoothing plate is smoothing the pole ear, there will be relative movement between the smoothing plate and the pole ear, which makes it easy for the smoothing plate and the pole ear to be scratched, causing damage to the pole ear.

In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0033] Embodiment 1:

[0034] This embodiment provides a roller mechanism for preventing the tab from being folded, comprising:

[0035] A receiving roller 1, wherein the receiving roller 1 is used to rotate the traction pole piece 8 for routing;

[0036] Two smoothing rollers 2, the two smoothing rollers 2 are respectively arranged on both sides of the receiving roller 1;

[0037] A smoothing belt 3, which is arranged on two smoothing rollers 2 and moves with the rotation of the smoothing rollers 2, and a part of the smoothing belt 3 is wrapped around the outside of the smoothing rollers 2;

[0038] A smoothing gap is formed between the receiving roller 1 and the smoothing belt 3 for the pole lug to pass through, and the smoothing belt 3 moves synchronously with the pole piece 8 to smooth the pole lug of the pole piece 8 .

[0039] In this technical solution, if Figure 2As shown, the receiving roller 1 rotates to pull the pole piece 8 to pass through the receiving roller 1, and at the same time, the two smoothing rollers 2 also rotate. The rotation of the two smoothing rollers 2 drives the smoothing belt 3 to move synchronously with the pole piece 8. When the pole ear on the pole piece 8 passes through the smoothing gap between the receiving roller 1 and the smoothing belt 3, the smoothing belt 3 moves synchronously with the pole ear, and the smoothing belt 3 will contact the pole ear to smooth the warped pole ear, thereby preventing the pole ear from being folded. In addition, the installation position of the two smoothing rollers 2 is not limited to the two sides of the receiving roller 1, and can be adjusted according to the roller angle of the pole piece 8 on the receiving roller 1 to ensure that the smoothing belt 3 can fully smooth the pole ear of the pole piece 8.

[0040] Since the smoothing tape 3 and the pole ear move synchronously, there is no relative displacement between the smoothing tape 3 and the pole ear, so that there is no relative scratch between the smoothing tape 3 and the pole ear when they move. Therefore, the smoothing tape 3 can not only smooth the pole ear, but also better protect the shape of the pole ear and prevent damage to the pole ear.

[0041] To sum up, through this structural design, the rotation of the smoothing roller 2 drives the smoothing belt 3 and the pole piece 8 that passes through the receiving roller 1 to move synchronously, and the smoothing belt 3 is used to smooth the warped pole ear on the pole piece 8. At the same time, there will be no relative scratches between the smoothing belt 3 and the pole ear, which effectively protects the shape of the pole ear and prevents the pole ear from being damaged.

[0046] In this technical solution, a first transmission assembly is arranged between the receiving roller 1 and the smoothing roller 2.

[0047] Furthermore, the first transmission assembly includes:

[0048] A first gear 4, wherein the first gear 4 is arranged on the receiving roller 1;

[0049] A second gear 5, wherein the second gear 5 is arranged on one of the smoothing rollers 2;

The second gear 5 drives the smoothing roller 2 to rotate. The smoothing roller 2 drives the third gear 6 to rotate. The third gear 6 drives the chain 7 to move. Since the chain 7 is connected to the smoothing belt 3, when the chain 7 moves, it will drive the smoothing belt 3 to move synchronously.

[0062] Through this structural design, when the receiving roller 1 rotates to pull the pole piece 8 to follow the line, the smoothing belt 3 and the pole piece 8 can move synchronously, thereby ensuring that the warped pole ears on the pole piece 8 will not be scratched and damaged while being smoothed, and the practicality is high.
