Abstract

Provided are a roller assembly, a battery cell manufacturing device, and an adjustment method of a roller, which relates to the field of battery manufacturing technology. The roller assembly includes a holder, a roller, and a first adjusting member. The roller is rotatably mounted on the holder. The first adjusting member is rotatably mounted on the holder, and one end of the roller is rotatably connected to the first adjusting member. A rotation axis of the roller does not coincide with a rotation axis of the first adjusting member. One end of the roller is rotatably mounted on the holder through the first adjusting member. The rotation axis of the first adjusting member does not coincide with the rotation axis of the roller, and therefore, rotation of the first adjusting member is capable of driving a corresponding end of the roller to rotate, thereby adjusting an extension direction of the roller.

First claim

The invention claimed is:

1. A roller assembly comprising:
a holder;
a roller rotatably mounted on the holder;
a first adjusting member rotatably mounted on the holder, one end of the roller being rotatably connected to the first adjusting member;
a second adjusting member, wherein the first adjusting member is mounted on the holder through the second adjusting member, the second adjusting member is rotatably mounted on the holder, and the first adjusting member is rotatably mounted on the second adjusting member;
a rotation axis of the second adjusting member does not coincide with a rotation axis of the first adjusting member; and
a first locking mechanism, and the first locking mechanism is configured to lock the second adjusting member and the holder; and
wherein a rotation axis of the roller does not coincide with the rotation axis of the first adjusting member.

2. The roller assembly according to claim 1 , wherein the second adjusting member is provided with a mounting hole, and the mounting hole is used for mounting the first adjusting member.

3. The roller assembly according to claim 2 wherein the second adjusting member sleeves the first adjusting member peripherally.

4. The roller assembly according to claim 2 , wherein an outer circumferential surface of the first adjusting member forms a rotational fit with a wall of the mounting hole.

5. The roller assembly according to claim 2 , wherein the first adjusting member is provided with an assembling hole, and the assembling hole is configured to mount the roller.

6. The roller assembly according to claim 5 , wherein a distance between a central axis of the assembling hole and the rotation axis of the first adjusting member is equal to a distance between a central axis of the mounting hole and the rotation axis of the second adjusting member.

7. The roller assembly according to claim 1 , wherein the first locking mechanism comprises a first locking member;
the holder is provided with a first locking hole, the second adjusting member is provided with a second locking hole, and the first locking member is configured to be inserted into the first locking hole and the second locking hole to lock the second adjusting member and the holder.

8. The roller assembly according to claim 1 , wherein the roller assembly further comprises a second locking mechanism, and the second locking mechanism is configured to lock the first adjusting member and the second adjusting member.

9. The roller assembly according to claim 8 , wherein the second locking mechanism comprises a second locking member;
the second adjusting member is provided with a third locking hole, the first adjusting member is provided with a fourth locking hole, and the second locking member is configured to be inserted into the third locking hole and the fourth locking hole to lock the first adjusting member and the second adjusting member.

10. The roller assembly according to claim 1 , wherein an axis of the second adjusting member coincides with the rotation axis of the second adjusting member.

11. The roller assembly according to claim 1 , wherein an axis of an outer circumferential surface of the first adjusting member coincides with the rotation axis of the first adjusting member.

12. The roller assembly according to claim 1 , wherein the roller assembly comprises a third locking mechanism, and the third locking mechanism is configured to lock the first adjusting member and the holder.

13. The roller assembly according to claim 1 , wherein the first adjusting member is a first adjusting member and the roller assembly further comprises a second first adjusting member, and both ends of the roller are respectively mounted on the holder through the two first adjusting members.

14. The roller assembly according to claim 1 , wherein the roller assembly further comprises a measuring member, the measuring member is mounted on the holder, and the measuring member is configured to measure a rotation angle of the first adjusting member.

15. A battery cell manufacturing device, comprising:
a feeding apparatus for providing an electrode sheet; and
a roller assembly according to claim 1 , wherein a roller of the roller assembly is configured to transfer the electrode sheet.

16. An adjustment method of a roller, comprising:
providing a holder, the roller, a first adjusting member, a second adjusting member and a first locking mechanism;
rotatably mounting the roller and the first adjusting member on the holder, and rotatably mounting one end of the roller to the first adjusting member, so that a rotation axis of the roller does not coincide with a rotation axis of the first adjusting member, wherein the first adjusting member is mounted on the holder through the second adjusting member, the second adjusting member is rotatably mounted on the holder, and the first adjusting member is rotatably mounted on the second adjusting member, and a rotation axis of the second adjusting member does not coincide with the rotation axis of the first adjusting member;
locking the second adjusting member and the holder; and
rotating the first adjusting member to adjust an extension direction of the roller.
