[0046] [Mode for Invention]
[0047] Hereinafter, the present disclosure will be described in detail with reference to the attached drawings. However, this is merely illustrative and the present disclosure is not limited to the specific embodiments described illustratively.
[0048] Specific terms used in this specification are for convenience of explanation only and are not intended to limit the exemplified embodiments.
[0049] For example, expressions such as “identical” and “identical” indicate not only a strictly identical state, but also a state in which there is a tolerance or a difference in the degree to which the same function is obtained.
[0050] For example, expressions indicating relative or absolute arrangements such as “in a certain direction,” “along a certain direction,” “parallel,” “perpendicular,” “to the center,” “concentric,” or “coaxial” not only strictly indicate such arrangements, but also indicate a state of relative displacement with a tolerance or an angle or distance such that the same function is obtained.
[0051] To explain the present disclosure, the following description is based on a spatial orthogonal coordinate system formed by mutually orthogonal five axes, the Y-axis, and the Z-axis. Each axis direction (X-axis direction, Y-axis direction, Z-axis direction) refers to both directions in which each axis extends.
[0052] The five directions, five directions, and Z direction mentioned below are for the purpose of explaining the present disclosure so that it can be clearly understood, and it goes without saying that each direction may be defined differently depending on where the reference is placed.
[0053] The use of terms such as 'first, second, third,' etc., attached to the components mentioned below is intended solely to avoid confusion regarding the components being referred to, and is unrelated to the order, importance, or master-subordinate relationship between the components. For example, an invention including only the second component without the first component can also be implemented.
[0054] The terms used in this disclosure are for the description of specific embodiments and are not intended to limit the scope of the claims. As used in the description of embodiments and in the appended claims, the singular form is intended to include the plural form unless the context clearly indicates otherwise.
[0055] FIG. 1 is a perspective view of an electrolyte supply device according to one embodiment of the present disclosure, and FIG. 2 shows the cover portion separated from the electrolyte supply device according to one embodiment of the present disclosure.
[0056] The electrolyte supply device (1) of the present disclosure can supply an electrolyte between a drum on which a copper foil is electrodeposited and a counter electrode.
[0057] An electrolytic cell is a reaction space into which an electrolyte is supplied, and a drum acting as a cathode and a counter electrode acting as an anode may be disposed inside. The electrolyte can be supplied between the drum and the counter electrode to induce an electrochemical reaction. When current is applied to the drum and the counter electrode, copper ions in the electrolyte move to the cathode drum and are reduced, and as a result, a copper foil can be electrodeposited on the surface of the drum. The electrolyte supply device (1) of the present disclosure can supply the electrolyte more uniformly and stably between the drum and the counter electrode during this electrodeposition process.
[0058] The electrolyte supply device (1) of the present disclosure includes a first inlet section (110) into which the electrolyte flows and a first outlet section (120) into which the electrolyte flows out, each comprising a plurality of receiving sections (100) arranged along a first direction parallel to the width direction of the drum, a partition section (300) arranged between each of the plurality of receiving sections (100), a dispenser section (500) extending in the first direction and arranged between the drum and the plurality of receiving sections (100), a mixing section (200) extending in the first direction and arranged between the plurality of receiving sections (100) and the dispenser section (500) and communicating with each of the plurality of receiving sections (100), and a cover section (400) arranged on each side of the plurality of receiving sections (100). Electrolyte may be introduced into one side of the above-mentioned electrolyte supply device (1) and may be discharged from the other side. The area where the electrolyte is introduced may be connected to an external storage tank. A supply pipe (620) may supply the electrolyte contained in the storage tank to the above-mentioned electrolyte supply device (1). A drum and a counter electrode may be disposed on the other side of the above-mentioned electrolyte supply device (1). The above-mentioned electrolyte supply device (1) may supply the electrolyte between the drum and the counter electrode.
[0059] Referring to FIG. 1, the plurality of receiving portions (100) may be arranged along the width direction of the drum. In this specification, a direction parallel to the width direction of the drum may be defined as a first direction (e.g., the X-axis direction of FIG. 1).
[0060] The dispenser section (500) may be positioned between the plurality of receiving sections (100) and the drum. Additionally, the mixing section (200) may be positioned between the plurality of receiving sections (100) and the dispenser section (500). That is, the electrolyte may be introduced into one side of the plurality of receiving sections (100) and supplied to the drum via the mixing section (200) and the dispenser section (500).
[0061] Each of the above plurality of receiving sections (100) may include an inlet section and an outlet section. In this specification, the inlet section included in each of the receiving sections (100) may be defined as a first inlet section (110), and the outlet section included in each of the receiving sections (100) may be defined as a first outlet section (120).
[0062] The plurality of receiving sections (100) are each connected to different supply pipes (620), and each receiving section (100) can receive an electrolyte through each first inlet section (110). The physical characteristics (e.g., copper ion concentration, flow rate, etc.) of the electrolyte supplied to each receiving section (100) may differ. The quality of the copper foil can be controlled by adjusting the physical characteristics of the electrolyte. Specifically, the plurality of receiving sections (100) are arranged along the width direction of the drum, and since electrolytes of different characteristics are supplied along the width direction of the drum, copper foil having different characteristics depending on the width direction of the drum can be manufactured. That is, by adjusting the electrolyte supply conditions of each receiving section, the width direction characteristics of the copper foil affected by each receiving section can be controlled, and copper foil satisfying a predetermined specification can be manufactured.
[0063] It is necessary to prevent the electrolyte from mixing within the plurality of receiving sections (100). The partition section (300) may be placed between the plurality of receiving sections (100). Along the first direction, the partition section (300) may be placed between the plurality of receiving sections (100). The partition section (300) may be provided in multiple numbers. The partition section (300) may be arranged intersectingly with the plurality of receiving sections (100). Referring again to FIG. 1, the partition section (300), receiving section (100), partition section (300), and receiving section (100) may be arranged repeatedly. Through this arrangement structure, direct communication between two adjacent receiving sections (100) can be prevented, and the electrolyte contained in the two receiving sections (100) can be prevented from mixing directly. As will be described later, each of the plurality of receiving sections (100) has a receiving space (130) that is indirectly connected by the mixing section (200), and the electrolyte contained in the plurality of receiving sections (100) can be transferred to the mixing section (200) and mixed.
[0064] The mixing section (200) may be positioned on one side of the plurality of receiving sections (100). One side of the mixing section (200) may be connected to the first discharge section (120), and the other side of the mixing section (200) may be connected to the dispenser section (500). The plurality of receiving sections (100) and the dispenser section (500) may be connected through the mixing section (200).
[0065] The mixing section (200) may include a first plate (211) and a second plate (215) spaced apart along a second direction parallel to the circumferential direction of the receiving section (100). In this specification, the second direction may be defined as a direction parallel to the circumferential direction of the receiving section (100). Referring to FIGS. 1 and 2, the first plate (211) may extend along the first direction. The second plate (215) may extend along the first direction. The first plate (211) and the second plate (215) may be arranged parallel to each other.
[0066] The mixing space (220) may be formed by the first plate (211) and the second plate (215). The mixing space (220) may be continuously extended along the first direction. In other words, the electrolyte may move along the first direction within the mixing space (220). The mixing space (220) may be in communication with each of the plurality of receiving portions (100). After the electrolyte is transferred from the plurality of receiving portions (100) to the mixing space (220), the electrolyte may be mixed.
[0067] The mixing section (200) can prevent stains from forming on the surface of the copper foil. When the electrolyte is supplied from the plurality of receiving sections (100) to the drum, stains may form on the surface of the copper foil due to the vortex of the electrolyte. The vortex of the electrolyte can be reduced by the mixing space (220).
[0068] The first plate (211) and the second plate (215) may be coupled to the corners of the first outflow section (120). The first plate (211) may be coupled to one corner of the first outflow section (120) and the second plate (215) may be coupled to the other corner of the first outflow section (120). Through this structure, the electrolyte flowing out from the first outflow section (120) can be transferred into the mixing section (200). The cover section (400) may be disposed on each side of the plurality of receiving sections (100). The cover section (400) may be disposed on one side and the other side of the plurality of receiving sections (100) along the first direction. At least a portion of the cover section (400) may be disposed inside the mixing section (200). Referring to FIG. 2, at least a portion of the cover portion (400) may be positioned between the first plate (211) and the second plate (215). The cover portion (400) may seal one side and the other side of the mixing space (220) along the first direction, respectively. By doing so, the cover portion (400) can prevent the electrolyte from being discharged to the outside of the mixing portion (200) along the first direction. The cover portion (400) will be described in detail with reference to FIG. 5 and FIG. 6.
[0069] The electrolyte supply device (1) of the present disclosure may further include a dispenser section (500). The drum may be disposed on one side of the dispenser section (500), and the mixing section (200) may be disposed on the other side of the dispenser section (500). Referring to FIG. 2, the drum may be disposed on the upper side of the dispenser section (500), and the mixing section (200) may be disposed on the lower side of the dispenser section (500). Through this structure, the electrolyte may be supplied from the mixing section (200) through the dispenser section (500) to the drum and the counter electrode.
[0070] The dispenser part (500) may include a first body (511) and a second body (515) spaced apart along the second direction. The electrolyte may be transferred from the mixing space (220) to a space spaced apart between the first body (511) and the second body (515). The first body (511) may extend along the first direction. The second body (515) may extend along the first direction. The first body (511) and the second body (515) may be arranged side by side.
[0071] Referring to FIGS. 1 and 2, the width of the first body (511) measured along the second direction may gradually narrow as it approaches the drum. The first body (511) may be shaped such that its width narrows from one side adjacent to the mixing section (200) to the other side adjacent to the drum. The first body (511) may include a first outer surface facing outward and a first inner surface facing the second body (515). The first outer surface may be formed as a flat surface, and the first inner surface may be formed as a curved surface. The slope of the curve of the first inner surface may become gentler as it approaches the drum.
[0072] The width of the second body (515) measured along the second direction may gradually narrow as it approaches the drum. The second body (515) may be shaped such that its width narrows from one side adjacent to the mixing section (200) to the other side adjacent to the drum. The second body (515) may include a second outer surface facing the outside and a second inner surface facing the first body (511). The second outer surface may be formed as a flat surface, and the second inner surface may be formed as a curved surface. The slope of the curve of the second inner surface may become gentler as it approaches the drum.
[0073] The distance between the first inner surface and the second inner surface along the second direction may increase as it approaches the drum. The first body (511) and the second body (515) may be symmetrical.
[0074] FIG. 3 is a partially exploded view of an electrolyte supply device (1) according to one embodiment of the present disclosure, and FIG. 4 is a partition section (300) according to one embodiment of the present disclosure.
[0075] Specifically, FIG. 3 illustrates a receiving section (100) positioned between two partition sections (300). The receiving section (100) may be cylindrical in shape. The axis of the receiving section (100) may be positioned parallel to the first direction. The first inlet section (110) may be a hole penetrating the outer surface of the receiving section (100). For example, the first inlet section (110) may be positioned on the lower surface of the receiving section (100).
[0076] The first outflow portion (120) may be a hole penetrating the outer surface of the receiving portion (100). The first outflow portion (120) may be a slit formed on the outer surface of the receiving portion (100). The first outflow portion (120) may extend from one side of the receiving portion (100) to the other side of the receiving portion (100) along the first direction. For example, the slit may extend along the first direction. Specifically, along the first direction, one side and the other side of the receiving portion (100) may each be connected to the partition portion (300). The slit may extend from one side of the receiving portion (100) to the other side. The receiving portion (100) may further include a housing (140). The flow rate of the electrolyte can be reduced through the housing (140), and the vortex can be reduced. The housing (140) can be placed inside the receiving portion (100). The housing (140) may include an inlet portion and an outlet portion. In this specification, the inlet portion included in the housing (140) may be defined as a second inlet portion (145), and the outlet portion included in the housing (140) may be defined as a second outlet portion (143). The electrolyte may be introduced into the housing (140) through the second inlet portion (145) and may be discharged outside the housing (140) through the second outlet portion (143).

[0078] Referring to FIGS. 2 and 3, the first inlet section (110) and the second inlet section (145) may overlap each other along the radial direction of the receiving section (100). This allows the supply pipe (620) to pass through the first inlet section (110) and the second inlet section (145) simultaneously. One end of the supply pipe (620) may be positioned inside the housing (140). The electrolyte transported through the supply pipe (620) may be supplied to the housing (140).
[0079] The second outflow section (143) may be a hole penetrating the outer surface of the housing (140). The diameter of the second outflow section (143) may be less than or equal to the diameter of the second inflow section (145). The second outflow section (143) may be provided in multiple numbers. The multiple second outflow sections (143) may be arranged in parallel along the first direction. Additionally, the multiple second outflow sections (143) may be arranged in parallel along the circumferential direction of the receiving section (100).

Referring to FIGS. 2 and 3, the lower surface of the housing (140) may mean a surface facing downward with respect to the Z-axis direction. The second outflow portion (143) may be disposed on the upper surface of the housing (140).
