This is to widely divide and bond the cut pieces of tape (t) to the folding surface (F) of the secondary battery (B) while minimizing the withdrawal of the tape (T).

On the other hand, the tape cutting pieces (t) are attached to the tape supply unit (100) under the condition that the first to third suction/attachment tables (252a, 252b, 25c) vacuum the tape (T) taken out of the tape supply unit (100). ) is between the tape T withdrawal start point and the second suction/adhesion table 252b, between the second suction/adhesion table 252b and the first suction/adhesion table 252a, and between the first suction/adhesion table 252a. ) and the third suction/attachment table 252b, it is formed in a state of vacuum adsorption on the first to third suction/attachment tables 252a, 252b, and 252c.

Here, the tape supply unit 100 pulls out the surface of the tape T to face the first to third suction/adhesion tables 252a, 252b, and 252c of the suction/adhesive means 250, and 3 Since it is a well-known technique that the suction/adhesion tables 252a, 252b, and 252c vacuum the tape T and the cut tape pieces t, and release the vacuum suction to the tape cut pieces t, Detailed descriptions are omitted.

In addition, since movement of the second and third suction/attachment tables 252b and 252c by the operation of the first and second width adjusting servomotors 266a and 266b is a well-known technique, a detailed description thereof will be omitted.

Hereinafter, an operating state of the tape attaching unit 200 for a pouch-type secondary battery taping device according to the present invention formed as described above will be briefly described.

When the surface of the tape T is pulled out from the tape supply unit 100 to face the tape attachment unit 200 according to the present invention, the linear moving means 230 extends the cylinder rod 234 of the transfer cylinder 232 The upper surfaces of the first and third suction/adhesion tables 252a, 252b, and 252c of the suction/adhesion unit 250 are brought into contact with the surface of the tape T drawn out from the tape supply unit 100.

At this time, the first and second width-adjusting servomotors 266a and 266b of the first and second width adjusting units 258a and 258b allow the second and third suction/attachment tables 252b and 252c to control the first suction/attachment table. It is moved so as to approach both ends of the attachment table 252a.

And when the upper surfaces of the first to third suction/attachment tables 252a, 252b, and 252c come into contact with the surface of the tape T drawn out from the tape supply unit 100, the first to third suction/attachment tables ( 252a, 252b, 252c) vacuum adsorbs the surface of the tape T, and at the same time, the tape supply unit 100 lifts and moves the cutters C (see FIG. 5) so that the tape supply unit 100 moves the tape T Between the withdrawal start point and the second suction/attachment table 252b, between the second suction/attachment table 252b and the first suction/attachment table 252a, and between the first suction/attachment table 252a and the third suction/attachment table 252a. It is cut between the attachment tables 252b.

At this time, the tape cut pieces t are formed on the first to third suction/attachment tables 252a, 252b, and 252c in a state of vacuum adsorption.

As described above, when the cut tape pieces t are formed, the transfer cylinder 232 returns the cylinder rod 234 to the first to third suction/attachment tables 252 vacuum adsorbing the cut tape pieces t. is returned to the side of the rotation frame 214. At this time, the first and second width adjusting servomotors 266a and 266b of the first and second width adjusting units 258a and 258b use the second and third suction/attachment tables ( 252b and 252c) are moved away from both ends of the first suction/attachment table 252a.

And at the same time, the servomotor 222 for determining the rotational position is the backside of the tape cutting pieces t vacuum-adsorbed on the first to third suction/attachment tables 252 of the secondary battery B guided to the tape bonding position. The rotating frame 214 is rotated so as to face the folding portion F.

On the other hand, when the back side of the tape cutting pieces (t) on which the adhesive layer is formed faces the folding portion (F) of the secondary battery (B), the linear moving means 230 extends the cylinder rod 234 of the transfer cylinder 232 to The backsides of the cut pieces of tape (t) vacuum adsorbed on the first to third suction/attachment tables (252a, 252b, 252c) are brought into contact with the folding portion (B) of the secondary battery (B).

And when the cut tape pieces t are joined to the folding portion F, the first to third suction/attachment tables 252a, 252b, and 252c release the vacuum adsorption of the cut tape pieces t, at this time , The transfer cylinder 232 returns the cylinder rod 234 to return the first to third suction/attachment tables 252a, 252b, and 252c to the rotating frame 214 side.

On the other hand, if the tape cut pieces t formed in a state of being vacuum-sucked on the first to third suction/attachment tables 252a, 252b, and 252c are defective, the servomotors 222 for determining rotational positioning are configured to perform the first to third suction/attachment tables 252a, 252b, and 252c. The rotation frame 214 is rotated so that the suction/adhesion tables 252a, 252b, and 252c are guided to the tape discharge position, and at this time, the first to third suction/adhesion tables 252a, 252b, and 252c are defective tape pieces. The vacuum adsorption on the (t) is released so that the defective tape cut pieces (t) are discharged to the outside.
