Abstract

Examples of the present disclosure relate to a tape attaching apparatus of which an installation space is reduced, with productivity of tape attaching work improved, and accuracy of a tape attachment position is improved. Examples of the present disclosure include a tape attaching apparatus including a tape supply unit that supplies a tape, an electrode plate supply unit that supplies an electrode plate, and a rotating head that receives the tape supplied from the tape supply unit and rotates to attach the tape to the electrode plate supplied from the electrode plate supply unit.

First claim

What is claimed is:

1 . A tape attaching apparatus comprising:
a tape supply unit configured to supply a tape; an electrode plate supply unit configured to supply an electrode plate; and a rotating head configured to receive the tape supplied from the tape supply unit and to rotate so as to attach the tape to the electrode plate supplied from the electrode plate supply unit.

2 . The tape attaching apparatus as claimed in claim 1 , wherein the rotating head is configured to receive the tape from the tape supply unit at a tape transfer point, and is configured to rotate in one direction to attach the tape to the electrode plate at a tape attachment point.

3 . The tape attaching apparatus as claimed in claim 2 , wherein, the rotating head is further configured to rotate in the one direction to return to the tape transfer point when the tape is attached to the electrode plate at the tape attachment point.

4 . The tape attaching apparatus as claimed in claim 2 , wherein the tape includes an adhesive surface coated with an adhesive, and a non-adhesive surface which is opposite to the adhesive surface and is not coated with the adhesive, and
the rotating head is configured to adsorb the non-adhesive surface at the tape transfer point and to stop the adsorption of the non-adhesive surface at the tape attachment point.

5 . The tape attaching apparatus as claimed in claim 4 , wherein the rotating head is configured to push the tape toward the electrode plate to facilitate adhesion of the adhesive surface to the electrode plate at the tape attachment point.

6 . The tape attaching apparatus as claimed in claim 2 , wherein the rotating head comprises a plurality of rotating heads, and
the plurality of rotating heads are arranged at equiangular intervals with respect to the same rotation center.

7 . The tape attaching apparatus as claimed in claim 6 , further comprising a rotation frame configured to support the plurality of rotating heads, the rotation from being configured to rotate about the rotation center.

8 . The tape attaching apparatus as claimed in claim 2 , wherein the tape transfer point is comprises as a plurality of tape transfer points, the tape attachment point comprises a plurality of tape attachment points, and the number of tape transfer points is equal to the number of tape attachment points, and
a number of rotating heads is twice the number of tape transfer points and the number of tape attachment points.

9 . The tape attaching apparatus as claimed in claim 8 , wherein the tape is transferred to one of the plurality of rotating heads from the tape supply unit at one of the plurality of tape transfer points, transferred to the electrode plate from the one rotating head at one of the plurality of tape attachment points, and attached to the electrode plate, and
the tape transfer point and the tape attachment point are spaced apart from each other by about 180° with respect to a rotation center of the rotating head.

10 . The tape attaching apparatus as claimed in claim 8 , wherein a size of the tape transferred to one of the plurality of rotating heads at one of the plurality of tape transfer points is different from a size of the tape transferred to another of the plurality of rotating heads at another of the plurality of tape transfer points.

11 . The tape attaching apparatus as claimed in claim 8 , wherein the tape supply unit comprises a plurality of tape supply units in a one-to-one correspondence with the tape transfer points, and
the electrode plate supply unit comprises one electrode plate supply unit.

12 . The tape attaching apparatus as claimed in claim 1 , wherein the tape supply unit comprises:
a tape supply roller configured to substantially continuously supply the tape; and a tape cutter configured to cut the tape supplied from the tape supply roller to a preset length.

13 . The tape attaching apparatus as claimed in claim 12 , wherein the tape supply unit further comprises a tape gripper configured to grip an end portion of the tape fed from the tape supply roller.

14 . The tape attaching apparatus as claimed in claim 12 , wherein, the rotating head is configured to adsorb the tape when the tape gripper grips the tape, and
the tape cutter is configured to cut the tape when the tape is adsorbed to the rotating head.

15 . The tape attaching apparatus as claimed in claim 14 , wherein the tape supply unit further comprises a tape tension roller configured to pull the tape so that tension of the tape is substantially maintained.

16 . The tape attaching apparatus as claimed in claim 2 , wherein the electrode plate supply unit comprises:
an electrode plate supply roller configured to substantially continuously supply the electrode plate; and an electrode plate support configured to support the electrode plate at the tape attachment point.

17 . The tape attaching apparatus as claimed in claim 16 , wherein the electrode plate supply unit further comprises an electrode plate stopping roller configured to stop movement of the electrode plate passing through the tape attachment point when the tape is attached to the electrode plate.

18 . The tape attaching apparatus as claimed in claim 17 , wherein the rotating head is configured to rotate after adsorbing the tape at the tape transfer point, to move in a radial direction from a rotation center of the rotating head at the tape attachment point to attach the tape to the electrode plate, to stop the adsorbing of the tape, and to return toward the rotation center.

19 . The tape attaching apparatus as claimed in claim 17 , wherein the electrode plate supply unit further comprises an electrode plate tension roller configured to pull the electrode plate so that tension of the electrode plate is substantially maintained.

20 . The tape attaching apparatus as claimed in claim 16 , wherein the tape attachment point comprises a plurality of tape attachment points,
the electrode plate supply roller comprises one electrode plate supply roller, the electrode plate support comprises a plurality of electrode plate supports in a one-to-one correspondence with the tape attachment points, and the plurality of electrode plate supports are spaced apart from each other on a movement path of the electrode plate supplied from the electrode plate supply roller.
