[0003] Side Shield

[0004] [Technical Field]

[0005] The present invention relates to a side shield.

[0006] [Background Art]

[0007] The present invention relates to a side shield, and more particularly to a sealing structure for preventing leakage of electrolyte from the side of a drum of an electrolytic copper foil manufacturing device.

[0008] Generally, an electrolytic copper foil manufacturing device is equipped with an electrolytic cell through which an electrolyte circulates and a drum that rotates inside the cell to form a copper foil. Side shields are installed on both sides of the drum, and the side shields serve to maintain a constant flow of the electrolyte by blocking the minute gap between the side of the drum and the wall of the electrolytic cell.

[0009] Side shields are typically composed of plastic or rubber components and are designed to maintain a seal while operating in conjunction with the rotation of the drum. This structure plays a crucial role not only in preventing electrolyte leakage but also in ensuring pressure and flow stability within the electrolytic cell. However, in actual process environments involving prolonged operation, there is a possibility that the sealing performance may gradually deteriorate or leakage may occur due to the material or structural strength of the side shield. Furthermore, if wear or damage occurs to the side shield, replacement or repair is not easy, raising concerns about reduced operational efficiency of the device. Therefore, a side shield structure is required that can reliably maintain its sealing function even with changes in the electrolytic cell environment and is easy to maintain.[Disclosure]

[0039] FIGS. 1 to 4 illustrate a side shield (100) according to one embodiment of the present invention.

[0040] Referring to FIGS. 1 to 4, a side shield (100) according to one embodiment of the present invention can cover a cylindrical drum that rotates about an axis. A side shield (100) according to one embodiment of the present invention may include a body portion (110) disposed on one surface disposed in the axial direction of the drum, a recessed portion (120) extending along the circumferential direction of the drum from the outer surface of the body portion (110), and a wing portion (130) partially disposed on the recessed portion (120) and extending along the circumferential direction of the drum.

[0041] In the copper foil manufacturing process, the drum can be contained in an electrolytic cell. The electrolyte is contained inside the electrolytic cell, and the outer surface of the drum can rotate while in contact with the electrolytic cell, and copper foil can be electrodeposited on the outer surface of the drum.

[0042] The body portion (110) can prevent contact with the electrolyte on one axial surface of the drum. The body portion (110) can be positioned on one axial surface of the drum. The body portion (110) can form a space between itself and the drum. The body portion (110) can be formed in a shape corresponding to the drum. The drum may be formed in a cylindrical shape, and the body portion (110) may be formed in a semicircular shape. One edge of the body portion (110) may extend along the circumferential direction of the drum.

[0043] The body part (110) may include one or more holes (115). The holes may be formed on the outer surface of the body part (110). The holes are formed to penetrate the outer surface of the body part (110), so that when the electrolyte flowing between the drum and the body part (110) rises above a certain level, the electrolyte can be discharged through the holes. The position (or height) of the holes can be adjusted to control the electrolyte so that it does not rise above a certain level.

[0044] The body portion (110) may further include a cathode filler portion (119) and an electrolyte hole (113). An empty space may be formed inside the cathode filler portion (119). A cathode member (not shown) may be accommodated in the cathode filler portion (119). Electrolyte may move into the cathode filler portion (119) through the electrolyte hole (113). The cathode member may prevent copper ions from being deposited on the side of the drum. For example, the cathode member may be rod-shaped, but is not limited thereto.

[0045] The above-mentioned recess (120) may be placed on the outer surface of the body part (110). The above-mentioned recess (120) may extend along the circumferential direction of the drum. The above-mentioned wing part (130) may be placed on the above-mentioned recess (120) and extend along the circumferential direction of the drum. The above-mentioned wing part (130) may be in close contact with the body part (110) even when the drum is rotated, thereby preventing the electrolyte from flowing between the side shield (100) and the drum.

[0046] The recessed portion (120) may be positioned closer to the edge of the body portion (110) than to the center of the body portion (110). As previously described, the drum may include an axis. To avoid obstructing the path along which the axis of the drum extends, the body portion (110) may further include a receiving portion (117). Referring to FIG. 1, the receiving portion (117) may be formed in the center of the body portion (110) and be in a shape that is recessed inward. Here, the recessed portion (120) may be positioned closer to the edge of the body portion (110) than to the center of the body portion (110).

[0047] Specifically, FIG. 3 illustrates a cross-section in which the body portion (110) and the wing portion (130) are combined. The recessed portion (120) may extend along the circumferential direction of the drum.

[0048] The above-mentioned recess (120) is not a simple uneven structure, but can serve as a guide groove for joining the inclined surface of the wing portion (130). The above-mentioned recess (120) may include an inclined surface that forms a certain angle with the outer surface of the body portion (110). The inclined surface is formed so that its depth increases as it moves away from the axis of the drum, and then becomes shallow again at a certain point. Due to this inclined shape, one end of the wing portion (130) can be in close contact with the inclined surface, while the other end of the wing portion (130) can be spaced apart from the outer surface of the body portion (110). Additionally, a gap angle can be formed between the wing portion (130) and the body portion (110).

[0049] One edge of the wing portion (130) may extend along the circumferential direction of the drum. The wing portion (130) may be arc-shaped. Referring again to FIGS. 1 and FIGS. 3, the wing portion (130) may be formed in an arc shape, such that the inner edge is joined to the recessed portion (120) and the outer edge is spaced apart from the body portion (110). Meanwhile, the edge of the wing portion (130) may be located inward from the edge of the body portion (110).

[0050] The above side shield (100) may further include a cushioning member (230). The cushioning member (230) may be disposed on one side of the wing portion (130) that is coupled to the body portion (110). Referring to FIG. 3, the cushioning member (230) may be disposed between the inclined surface and one end of the wing portion (130).

[0051] The above cushioning member (230) can absorb micro-vibrations, shocks, etc. caused by the rotation of the drum and internal pressure fluctuations of the electrolytic cell. In addition, the above cushioning member (230) can prevent wear of the wing portion (130) or the body portion (110) due to friction. The above cushioning member (230) may be extended along the circumferential direction of the drum in a continuous ring shape or arranged in a plurality of segments. The above cushioning member (230) may be a sealing washer or an O-ring, but is not limited thereto.

[0052] The above side shield (100) may further include a connecting member (210). The connecting member (210) may connect the body part (110) and the wing part (130). The connecting member (210) may connect the body part (110) and the wing part (130) to each other and provide a bonding force so that the relative position between each member is not deformed even with vibration or changes in internal pressure of the electrolytic cell during operation.

[0053] The above-mentioned connecting members (210) may be provided in multiple numbers, and the multiple connecting members (210) may be arranged along the circumferential direction of the drum to distribute a uniform fastening load over the entire circumference of the side shield (100). The connecting members (210) may be mechanical fastening means such as bolts, screws, rivets, or fastening pins, but are not limited thereto.

[0054] In particular, the connecting member (210) is formed to be easy to fasten and unfasten, so that the side shield (100) can be easily maintained. When the side shield (100) is joined to the body part (110) by welding, there is a problem with difficult maintenance. When replacing the wing part (130), the side shield (100) is separated from the drum, the worn wing part (130) is removed, and a new wing part (130) is re-welded to the body part (110). However, in the side shield (100) according to one embodiment of the present invention, the wing part (130) and the body part (110) can be easily separated, so work efficiency is improved.

[0055] Specifically, FIG. 4 illustrates the appearance of a wing portion (130) coupled to a body portion (110). A side shield (100) according to one embodiment of the present invention may further include a sealing member (220). The sealing member (220) may be positioned between the corner of the wing portion (130) and the body portion (110). As described above, one end of the wing portion (130) may be positioned in the recess (120), and the other end of the wing portion (130) may be positioned spaced apart from the body portion (110). Here, the sealing member (220) may be positioned between the other end of the wing portion (130) and the body portion (110). The sealing member (220) may extend along the circumferential direction of the drum.

[0056] The wing portion (130) can be in close contact with one axial surface of the drum, and the electrolyte can be prevented from flowing between the wing portion (130) and one axial surface of the drum. The sealing member (220) is formed of an elastic material so that the wing portion (130) can be stably in contact with one axial surface of the drum. The sealing member (220) can increase the contact force by pressing the wing portion (130) toward one axial surface of the drum through elastic force. In addition, the sealing member (220) can cushion the pressing force to prevent damage to the drum.

[0057] The sealing member (220) may include a first core (221) and a second core (225). The first core (221) may contact the body part (110), and the second core (225) may contact the wing part (130). The first core (221) and the second core (225) may be connected to each other to form an integral unit. For example, the sealing member (220) may be U-shaped. The first core (221) and the second core (225) may be connected to form a predetermined angle. Through this, the second core (225) can press the wing part (130) while the first core (221) is fixed to the body part (110).

[0058] The body portion (110) may further include a body groove (116). The body groove (116) may be positioned on one side of the body portion (110) facing the drum. The body groove (116) is formed as a recessed structure, and a portion of the sealing member (220) may be seated in the body groove (116). The body groove (116) may extend along the circumferential direction of the drum. Referring to FIG. 4, the sealing member (220) may be seated in the body groove (116). This allows the sealing member (220) to be stably fixed without changing its position on the body portion (110) even when the sealing member (220) presses the wing portion (130).

[0059] The present invention may be implemented in various modified forms, and the scope of rights is not limited to the embodiments described above. The contents described above are merely examples of applying the principles of the present invention, and other configurations may be further included within the scope of the present invention.
