A commonly used polyolefin-based resin layer is CPP (Casted Polypropylene).

The pouch-type secondary battery can have flexibility in shape and has the advantage of being able to implement a secondary battery of the same capacity with a smaller volume and mass.

In the manufacturing process of such a pouch-type battery, a battery assembly including a negative electrode, a separator, and a positive electrode is put in a pouch-type packaging material, an electrolyte is injected, and the edges are sealed. Then, the battery is activated through several charge/discharge cycles.

To this end, the rotation driving unit 63 is rotated in the forward or reverse direction by the power of the motor 631 and the motor 631 coupled to the bottom surface of the second side plate 93, and a rotating shaft 632 having a spiral formed on the outer periphery. , a transfer body 633 having a spiral fastened with the spiral of the rotary shaft 632 on the inner periphery, and coupled to the upper and lower sides of the second side plate 93 with the transfer body 633 interposed therebetween, the rotary shaft 632 ) may include a rotation guide block 634 for guiding the forward or reverse rotation.

Only one motor 631 , the rotary shaft 632 , and the transfer body 633 may be applied.

The transfer body 633 includes a coupling block 6331 coupled to the operation plate 621 . Accordingly, the transfer body 633, the operation plate 621, and the rack 62 are raised or lowered at the same time.

The motor 631 rotates the rotating part 40 at an angle of 90° so that the rotating part 40 is in contact with the upper surface of the seating part 30 .

For example, when the motor 631 rotates in the forward direction, the transfer body 633 rises along the spiral of the rotating shaft 632 , and thus the rack 62 also rises while rotating the pinion gear 61 at a predetermined angle. make it

Accordingly, the rotating part 40 folds the folding area 122 into the base part 123 while rotating in the downward direction, that is, in the direction of the seating part 30 .

In other words, the folding part 121 can be folded twice by 90 degrees through the first folding part 20 and the second folding part 60 , and the second folding part 60 has the folding area 122 . It is folded to be seated on the upper surface of the base part 123 .

At this time, in the process of folding the folding area 122 through the interaction between the second folding unit 60 and the rotating unit 40, the additional elevating driving unit 53 or the precision adjusting elevating driving unit 54 is the pressing unit 51 ) to separate the pressing blade 51a from the folding part 121 .

Accordingly, the folding area 122 is folded while the rotating part 40 smoothly rotates.

In this way, after the folding part 121 is secondarily folded, the motor 631 returns the rotary shaft 632 to its original position. Accordingly, the rotation unit 40 is rotated upward to return to the original state.

Thereafter, the loading unit 110 transfers the pouch-type secondary battery 120 to the third installation member 100 .

The shape maintaining part 70 is configured to simultaneously press the upper surface of the folding area 122 folded by the second folding part 60 and the bottom surface of the base part 123 .

The shape maintaining part 70 is composed of two pairs and is disposed so as to face the top and bottom surfaces of the third installation member 100 up and down.

Of course, when the support part 10, the first folding part 20, the seating part 30, the rotating part 40, the pressing part 50, and the second folding part 60 are applied as two, the shape maintaining part ( 70) can be applied in two pairs.

Specifically, the shape maintaining unit 70 includes a pair of presses 71 and presses 71 that are opposed to the bottom surface of the folding area 122 and the base part 123 and the top surface of the folding area 122, respectively, to the folding area ( 122) and the base portion 123 may include a lift driving unit 72 for pressing or spaced apart, respectively.

The press 71 is formed of a material having excellent thermal conductivity, and a heating wire is embedded therein. The heating wire may be heated by receiving external power.

The lift driving unit 72 may be formed of a cylinder. Therefore, as the piston of the lifting drive part 72 rises or descends, the press 71 applies heat while pressing the folding area 122 and the base part 123 so that the folding state of the folding part 121 is continuously maintained. to keep it
