The rust-preventing liquid spraying unit 6 may be implemented as a rust-preventing liquid spraying device according to the present invention. As the rust preventive liquid spraying unit 6 sprays the rust preventive liquid on the copper foil, the electrodeposited copper foil manufacturing apparatus 1 according to the present invention can improve the uniformity of the rust preventive treatment on the copper foil. Looking at this in detail, it is as follows.

First, when the rust prevention treatment is performed on the copper foil only by the rust prevention treatment unit 5 without the rust prevention liquid spraying unit 6 , the rust prevention treatment for the first surface 210 of the copper foil in contact with the rust prevention roller 52 and A difference occurs in the rust prevention treatment of the second surface 220 opposite to the first surface 210 . As the first surface 210 contacts the rust prevention roller 52, contact with the rust prevention liquid is limited, whereas the second surface 220 has the first surface 210 on the rust prevention roller 52. ) because it is maintained in continuous contact with the rust preventive solution even in the state of being in contact with it. The first surface 210 may correspond to a shiny surface in contact with the negative electrode roller 21 . In this case, the second surface 220 may correspond to a matte surface. The first surface 210 may correspond to a matte surface, and the second surface 220 may correspond to a shiny surface.

Next, when the rust preventive liquid spraying part 6 is provided, the rust preventive liquid spraying part 6 may be implemented to spray the rust preventive liquid on the first surface 210 of the copper foil. Accordingly, since the rust-preventing liquid is additionally sprayed on the first surface 210 that has been in contact with the rust-preventing roller 52 , the electrodeposited copper foil manufacturing apparatus 1 according to the present invention provides an anti-rust treatment for the first surface 210 . And it is possible to reduce the deviation of the rust prevention treatment for the second surface (220). Therefore, the electrodeposited copper foil manufacturing apparatus 1 according to the present invention can improve the uniformity of the anti-rust treatment on the copper foil, and thus it is possible to manufacture a copper foil having improved quality.

The rust preventive liquid spraying unit 6 may spray the rust preventive liquid to the copper foil that has moved to the outside of the rust preventive liquid accommodated in the immersion tank 51 past the rust preventive roller 52 . In this case, the rust-preventing liquid spraying unit 6 may be disposed between the rust-preventing roller 52 and the first surface 210 of the copper foil.

The rust-preventing liquid spraying unit 6 may include a spraying body 61 , and a pulverizing chain 62 .

The injection body 61 is to accommodate the rust preventive solution. The spray body 61 may form the overall appearance of the rust preventive liquid spray unit 6 . The spray body 61 may be disposed between the rust prevention roller 52 and the first surface 210 of the copper foil. Although not shown, if the position can improve the uniformity of the rust prevention treatment for the copper foil, the injection body 61 may be arranged at another position.

The left-right direction (Y-axis direction) is an axial direction parallel to the width direction of the copper foil.

Since the accommodating space 611 is formed to decrease in size as it extends from the rear surface 61a toward the front surface 61b, the rust preventive liquid spraying unit 6 prevents the rust preventive liquid from being discharged from the rear surface 61a. It may be implemented to diffuse in the left-right direction (Y-axis direction) while flowing toward the front surface 61b. Accordingly, the rust-preventing liquid spraying unit 6 may uniformly spray the rust-preventing liquid in the width direction of the copper foil through the crushing chain 62 . In addition, since the pressure of the rust preventive liquid spraying unit 6 increases while the rust preventive liquid flows from the rear surface 61a to the front surface 61b, the spray pressure of the rust preventive liquid to the copper foil can be increased.

The injection body 61 has an upper surface 61e on the rear surface 61a so that the receiving space 611 is formed to be reduced in size as it extends from the rear surface 61a to the front surface 61b. As it extends toward the front surface 61b, it may be inclined to approach the lower surface 61f. The upper surface 61e and the lower surface 61f may be spaced apart from each other in the height direction (Z-axis direction) and disposed to face each other. The lower surface 61f may be disposed below the upper surface 61e. The height direction (Z-axis direction), the left-right direction (Y-axis direction), and the front-back direction (X-axis direction) may be axial directions with respect to the lower surface 61f. The left-right direction (Y-axis direction) and the front-back direction (X-axis direction) are axial directions disposed perpendicular to each other on the lower surface 61f. The height direction (Z-axis direction) is an axial direction perpendicular to each of the left-right direction (Y-axis direction) and the front-back direction (X-axis direction). The upper surface 61e and the lower surface 61f may be coupled to the rear surface 61a, the front surface 61b, the left surface 61c, and the right surface 61d, respectively.

The grinding chain 62 is to spray the rust preventive solution. The crushing chain 62 may be formed through the front surface 61b. Accordingly, the splitter chain 62 communicates the accommodating space 611 and the outside of the injection body 61, thereby spraying the rust preventive solution accommodated in the accommodating space 611 to the outside of the injection body 61. can do. The grinding slit 62 may be formed in the form of a slit having a longer length in the left-right direction (Y-axis direction) than in the height direction (Z-axis direction). Based on the left-right direction (Y-axis direction), the crushing chain 62 may be formed to have the same length as the width of the copper foil or may be formed to have a longer length than the width of the copper foil. The grinding chain 62 may be disposed to face the first surface 210 of the copper foil.

The distribution plate 63 may be disposed inside the injection body 61 . In this case, the distribution plate 63 may be coupled to each of the upper surface 61e, the lower surface 61f, the left surface 61c, and the right surface 61d. Accordingly, the distribution plate 63 may block the rust preventive liquid injected into the supply space 612 from flowing into the injection space 613 .

A plurality of distribution holes 631 may be formed in the distribution plate 63 . The distribution holes 631 may be formed to pass through the distribution plate 63 at positions spaced apart from each other. Accordingly, the distribution holes 631 may connect the supply space 612 and the injection space 613 . Accordingly, the rust preventive liquid injected into the supply space 612 may flow into the injection space 613 through the distribution holes 631 . In this process, the rust preventive solution injected into the supply space 612 may flow so as to spread in the left-right direction (Y-axis direction) toward the positions of the distribution holes 631 as shown in FIG. 7 . Therefore, the electrodeposited copper foil manufacturing apparatus 1 according to the present invention can induce the rust preventive solution to spread in the left and right direction (Y-axis direction) while passing through the distribution plate 63 through the distribution holes 631 . , it is possible to more uniformly spray the rust preventive solution in the width direction of the copper foil.

Among the distribution holes 631 , the first distribution holes 631a (shown in FIG. 6 ) have the lower surface 61f than the second distribution holes 631b among the distribution holes 6310 (shown in FIG. 6 ). . Accordingly, each of the first distribution holes 631a may have a lower flow rate through which the rust preventive solution passes per unit time than each of the second distribution holes 631b. 6) indicates that while the rust preventive solution is filled to the height at which the first distribution holes 631a are formed in the supply space 612, the spreadability of the rust preventive solution in the left and right direction (Y-axis direction) is greater, and the supply space In (612), while the rust preventive liquid exceeds the first distribution holes 631a and is filled to the height at which the second distribution holes 631b are formed, the fluidity of the rust preventive liquid flowing into the supply space 612 is greater. Accordingly, the rust preventive liquid spraying unit 6 uses the distribution plate 63 in which the first distribution holes 631a and the second distribution holes 631b are formed to apply the rust preventive liquid to the width of the copper foil. In addition to being able to spray uniformly in the direction, it is implemented so that the rust preventive solution can be smoothly sprayed onto the copper foil.

The first distribution holes 631a may be disposed at positions spaced apart from each other along the width direction of the copper foil. That is, the first distribution holes 631a may be spaced apart from each other in the left-right direction (Y-axis direction). The second distribution holes 631b may be disposed to be spaced apart from each other in the left and right direction (Y-axis direction) above the first distribution hole 631a. Although not shown, the distribution plate 63 may further include a third distribution hole disposed above the second distribution hole 631b.

The distribution protrusion 64 is positioned between the distribution plate 63 and the front surface 61b. The distribution protrusion 64 may protrude from the lower surface 61f and may be spaced apart from the upper surface 61e. Accordingly, the rust preventive solution passing through the distribution plate 63 is moved in the left and right direction (Y axis) by the distribution projection 64 until the distribution projection 64 is filled to a height protruding from the lower surface 61f. direction) is spread. Accordingly, the rust preventive liquid spraying unit 6 may induce the rust preventive liquid that has passed through the distribution plate 63 to further spread in the left and right direction (Y-axis direction) by the distribution protrusion 64 . Accordingly, the rust preventive liquid spraying unit 6 is implemented to more uniformly spray the rust preventive liquid in the width direction of the copper foil by using the distribution protrusion 64 .

The distribution protrusion 64 may be formed to contact each of the left surface 61c and the right surface 61d. Accordingly, the anti-rust liquid spraying part 6 is filled to a height at which the distribution protrusion 64 protrudes from the lower surface 61f and flows over the distribution protrusion 64 until the distribution protrusion (64). It can be implemented so that it cannot pass through. Accordingly, the rust preventive liquid spraying unit 6 can further improve the diffusivity of the rust preventive liquid by using the distribution protrusion 64 .

The distribution protrusion 64 may be formed in a shape that decreases in size as it protrudes from the lower surface 61f. The distribution protrusion 64 may be formed such that a surface facing the upper surface 61e forms a curved surface.
