The secondary battery electrode taping device (1) is a device that automatically performs a series of processes of extending, cutting, transferring the tape (T), and attaching the electrode (e) of the secondary battery (S1, S2).

Here, the electrode (e) of the secondary battery (S1, S2) may mean that the electrode (e) cells are stacked and the electrode (e) extended from the stacked electrode (e) cell.

In addition, the tape T may be made of an insulating material, and may have adhesive properties by applying an adhesive material to the other side. For example, the tape T may include a CPP tape T.

Specifically, a pair of fixed tapes (T) may include one side and another side that is positioned opposite the one side and has adhesive force. For example, as shown in FIG. 7, a pair of fixed tapes T includes a first tape T1 and a second tape T2 located below the first tape T1, The other side (T1b) of the first tape (T1) may be arranged to face the bottom, and the other side (T2b) of the second tape (T2) may be arranged to face the top.

A gripper 200 that selectively holds one end of the tape (T) and a transfer portion (300) that transfers the cut tape (T) in the second direction (D2) and attaches it to the electrodes (e) of the secondary batteries (S1, S2). ) may include.

Here, the second direction D2 may be perpendicular to the first direction D1. For example, the second direction D2 may be parallel to the y-axis, and the first direction D1 may be parallel to the x-axis.

Accordingly, the cutting unit 100 and the gripping unit 200 are arranged with each other in the first direction D1, and the transfer unit 300 is arranged and transferred in the second direction D2 perpendicular to the first direction D1. , they do not interfere with each other, and the space for arranging the cutting unit 100, the gripping unit 200, and the transfer unit 300 can be reduced.

6 and 7, the cutting part 100 includes a frame part 101 that rotatably seats a pair of fixed tapes T, and a second part where the gripping part 200 is located from the frame part 101. A fixing frame 110 extends in one direction (D1) and guides the tape (T) released from a pair of fixed tapes (T), and is arranged to face the fixing frame (110) and is optionally connected to the fixing frame (110). A fixed end 120 that fixes the tape T that has been released by contact and is disposed adjacent to the fixed end 120 to selectively cut the tape T fixed by the fixed frame 110 and the fixed end 120. It may include a blade portion 130.

The frame portion 101 may include a plate formed with an area of a certain amount or more in the vertical direction, and a pair of tapes T may be rotatably connected to one surface.

Specifically, a first tape (T1) and a second tape (T2) may be rotatably disposed on the frame portion 101, and the first tape (T1) may be located on top of the second tape (T2). there is.

In addition, when the first tape T1 is unwound, the other side T1b of the first tape T1, which has adhesive force, may be connected so that it faces downward. When the second tape T2 is unwound, the other side T2b of the second tape T2, which has adhesive force, may be connected to face the top.

The fixing frame 110 is connected to the frame portion 101 and extends from the frame portion 101 in the direction where the cut portion 100 is located to guide the released tape T toward the holding portion 200.

Specifically, the fixing frame 110 is disposed at a position facing the fixing end 120, and has a guide groove 111 for guiding the released tape T and one end of the fixing frame 110 facing the fixing tip 121a. It may include a buffer space 112 that is disposed adjacent to and prevents contact with the other surface having the adhesive force of the tape T.

The guide groove 111 may extend in a direction parallel to the direction in which the fixing frame 110 extends, and the released tape T is placed within the guide groove 111 so that the tape T moves in a preset direction. I can guide you.

The width of the guide groove 111 may be larger than the width of the tape T. Here, the guide groove 111 may be spaced apart so as not to contact the other surface of the adhesive tape T.

The buffer space 112 is arranged to face the fixed end 120 and is disposed adjacent to one end of the fixed frame 110 that is in contact with the fixed end 120, and the guide groove 111 is located in the lower direction of the fixed frame 110. ) can contain a space larger than that.

Here, the space larger than the guide groove 111 means that the guide groove 111 is dug from one side of the fixed frame 110 to a first depth (h1), whereas the buffer space 112 is dug to a first depth (h1). It can be dug to a larger second depth (h2).

Accordingly, when the tape (T) is fixed by one end and the fixed end 120 of the fixed frame 110, the buffer space 112 is a space where the other side of the tape T is in physical contact with the fixed frame 110. can be prevented.

For example, when the fixed end 120 moves to fix the tape T located between the fixed end 120 and the fixed frame 110, the other side of the tape T having adhesive force is fixed to the fixed frame 110. ), and as the other side of the tape (T) contacts the fixed frame 110, the area adjacent to the contacted tape (T) also contacts the fixed frame 110, and the other side of the tape (T) is in contact with the fixed frame 110 due to continuous contact. Adhesion may decrease.

In addition, the width w1 of the buffer space 112 may be smaller than or equal to the width of the adsorption unit 310.

Accordingly, the buffer space 112 can prevent the other surface of the tape T from contacting the fixing frame 110 during the process of extending or cutting the tape T, thereby reducing the adhesive strength. Thereafter, the tape T located in the buffer space 112 may be adsorbed by the adsorption unit 310 and attached to the electrodes e of the secondary batteries S1 and S2, which will be described later.

That is, the portion of the tape T located in the buffer space 112 may correspond to the portion attached to the electrode e of the secondary batteries S1 and S2.

Additionally, the fixed frame 110 may be composed of a pair.

At this time, the fixing tip 121a is formed in an arc shape, and when the fixing tip 121a contacts the fixing frame 110, the tape T located between the fixing tip 121a and the fixing frame 110 When fixing, the area in contact with the tape (T) can be reduced to a minimum.

That is, when the fixing tip 121a is in contact with the fixing frame 110, the fixing tip 121a has an arc shape and can press the tape T to the fixing frame 110 in a line-like shape. Accordingly, the tape (T) makes line contact with the fixed frame 110 rather than surface contact, thereby reducing the contact area of the other surface of the tape (T), thereby minimizing the loss area of contact force on the other surface of the tape (T).

In addition, the number of fixing tips 121a may correspond to the number of fixing frames 110.

It may include a second driving rail (E2) that moves and a body frame 102 that supports the first driving rail (E1) and the second driving rail (E2).

Here, the up-down direction may mean a direction approaching or moving away from the ground. For example, the upper direction may mean a direction away from the ground, and the lower direction may mean a direction closer to the ground. In addition, the vertical direction may mean a direction parallel to the z-axis.

In addition, the first driving rail (E1) and the second driving rail (E2) can operate independently under processor control.

The first driving rail (E1) and the second driving rail (E2) may have various mechanical configurations as long as they can move the blade portion 130 and the fixed end portion 120 in the vertical direction.
