[0018] Hereinafter, an embodiment of a wire deposition apparatus according to the present invention will be described with reference to the accompanying drawings. In the drawings, the thickness of wires and the size of components may be exaggerated for clarity and convenience. Furthermore, the terms used below are defined in consideration of the functions of the present invention and may vary depending on the intentions or practices of users and operators. Therefore, the definitions of these terms should be based on the overall content of this specification.

[0019] 1 is a schematic diagram of a wire deposition apparatus according to an embodiment of the present invention. Referring to FIG. 1, the wire deposition apparatus 1 according to the embodiment of the present invention includes a roller unit 10, a heater unit 20, and a cathode unit 30.

[0020] The wire 90 may be wound around two or more roller units 10 and moved. The roller units 10 are capable of changing their length on the shaft, so malfunctions can be prevented even when heated by the heater unit 20. For example, the roller units 10 may be arranged in pairs facing each other, or three or more roller units may be arranged. The wire 90 may be deposited while passing through each roller unit 10 several times.

[0021] The heater unit 20 can heat the wire 90 passing through the roller unit 10. For example, the heater unit 20 can be disposed between the roller units 10 and heat the wire 90 above the wire 90 passing through the roller units 10.

[0022] The cathode unit 30 can provide a deposition material to the wire 90. For example, the roller unit 10, the heater unit 20, and the cathode unit 30 can be housed in a chamber that can be converted to a vacuum state. The cathode unit 30 can include a cathode supply unit that is housed in the chamber and provides a deposition material, a cathode gas unit that supplies gas to the chamber, and a cathode power unit that supplies power to the chamber.

[0023] 2 is a diagram illustrating a roller unit according to an embodiment of the present invention. Referring to FIG. 2, the roller unit 10 according to an embodiment of the present invention may include a roller support portion 11, a roller shaft portion 12, and a roller absorber portion 13.

[0024] The roller support 11 may be fixedly installed in the chamber. For example, the roller support 11 may include a pair of first roller support parts 111 fixedly installed in the chamber to face each other, and a second roller support part 112 formed in the first roller support part 111 and into which the roller shaft part 12 can be inserted.

[0025] The second roller support part 112 may have a hole formed in the center of the first roller support part 111. The third roller support part 113 may be attached to the second roller support part 112. The third roller support part 113 may be a bearing.

[0026] The roller axle 12 may be rotatably mounted on the roller support 11. For example, both ends of the roller axle 12 may be inserted into the second roller support 112, and the roller axle 12 may be supported and rotated by the third roller support 113. The roller axle 12 may pass through the third roller support 113. The roller axle 12 may be supported by the third roller support 113, which is movable on the second roller support 112.

[0027] The roller absorbing portion 13 is disposed between the roller support portion 11 and the roller shaft portion 12, and can absorb the expansion of the roller shaft portion 12. As an example, the roller absorbing portion 13 can be built into the second roller support portion 112 to support the roller shaft portion 12.

[0028] The roller shaft 12 may pass through the roller absorbing portion 13. The roller absorbing portion 13 may form a vacant space in the second roller support portion 112. When the roller shaft 12 is heated and expands in length, the roller absorbing portion 13 may contract. The roller absorbing portion 13 may be in close contact with the third roller support portion 113.

[0029] More specifically, the roller shaft portion 12 may include a shaft rotating portion 121 , a shaft connecting portion 122 , and a shaft coupling portion 123 .

[0030] The shaft rotating portion 121 may be rotatably mounted on the roller support portion 11. A pair of shaft rotating portions 121 may be mounted on the roller support portions 11 at a distance from each other.

[0031] As an example, the axial rotation part 121 may include a first axial rotation part 181 inserted into the second roller support part 112 and engaged with the third roller support part 113, a second axial rotation part 182 extending from one end of the first axial rotation part 181, inserted into the third roller support part 113, and supported so as to be rotatable by the third roller support part 113, and a third axial rotation part 184 extending outward from the other end of the first axial rotation part 181.

[0032] The first and second rotating shaft parts 181 and 182 may have a cylindrical shape. The third rotating shaft part 183 may be formed at the end of the first rotating shaft part 181 and may have a disk shape. The diameter of the third rotating shaft part 183 may be larger than the diameter of the first rotating shaft part 181. The diameter of the second rotating shaft part 182 may be smaller than the diameter of the first rotating shaft part 181.

[0033] The shaft connecting portion 122 can connect a pair of shaft rotating portions 121. For example, the shaft connecting portion 122 can have a hollow cylindrical shape, and both ends can be stepped so that they can be locked onto the edges of the second shaft rotating portion 182.

[0034] The shaft coupling part 123 may couple the shaft rotating part 121 and the shaft connecting part 122. For example, the shaft coupling part 123 may include a first shaft coupling part 191 disposed to face the second shaft rotating part 182, and a second shaft coupling part 192 bent from the first shaft coupling part 191 to cover the end of the shaft connecting part 122.

[0035] The shaft coupling portion 123 may be disposed at one end or both ends of the shaft connecting portion 122. The third shaft rotating portion 183 may be connected to the first shaft coupling portion 191 by a bolt.

[0036] The wire 90 may be wound and moved directly on the outer periphery of the shaft connecting part 122. In addition, an additional roller support part 14, which is attached to the shaft connecting part 122 and around which the wire 90 is wound and moved, and an additional roller absorbing part 15, which maintains the surplus space of the shaft connecting part 122, may be additionally installed. When these are added, the operation of the wire 90 can be guaranteed in a double bearing system.

[0037] One or more roller additional support parts 14 may be arranged in the longitudinal direction of the shaft connecting part 122 to support the wire 90. As an example, the roller additional support part 14 may include a pair of first additional support parts 141 each having a ring shape and a second additional support part 142 arranged between the first additional support parts 141.

[0038] The outer diameter of the first additional support part 141 is larger than the outer diameter of the second additional support part 142. Therefore, when the wire 90 is placed on the second additional support part 142, the first additional support parts 141 placed on both sides can prevent the wire 90 from derailing.

[0039] The second additional support part 142 may serve as a bearing. The wire 90 is disposed on the second additional support part 142, thereby reducing friction that occurs during the movement of the wire 90. The roller additional support parts 14 may be arranged in series depending on the width of the wire 90 or the number of times the wire 90 is wound around the roller unit 10. When the roller additional support parts 14 are arranged in series, the first additional support parts 141 and the second additional support parts 142 may be arranged alternately.

[0040] A shaft mounting part 129 may be formed on the outer circumferential surface of the shaft connecting part 122. The shaft mounting part 129 may have a recessed groove shape so as to have a smaller outer diameter than the shaft connecting part 122.

[0041] The shaft mounting portion 129 extends from a set point to the end of the shaft connecting portion 122, and the roller additional support portion 14 can be inserted from the end to the set point. A shaft step portion 128 can be formed at the set point so that the roller additional support portion 14 can be locked.

[0042] The roller additional absorbing portion 15 is disposed between the roller additional support portion 14 and the shaft connecting portion 123, and can absorb expansion of the roller additional support portion 14. As an example, the roller additional absorbing portion 15 can be disposed between the shaft connecting portion 123 and a roller additional support portion 14 disposed at an edge of the roller additional support portions 14 disposed in a row.

[0043] The roller additional absorbing portion 15 can be selectively disposed between the roller additional support portions 14 arranged in a row. That is, the roller additional absorbing portion 15 can be disposed between a pair of opposing first additional support portions 141.

[0044] The roller absorber 13 and the roller additional absorber 15 may be wave washers or disc springs. As an example, the roller absorber 13 and the roller additional absorber 15 may be wave washers or disc springs.

[0045] Either the roller absorbing part 13 or the roller additional absorbing part 15 may be a wave washer, and the other may be a disc spring. When the shaft connecting part 122 expands, the roller absorbing part 13 contracts to secure a space for the expansion of the shaft connecting part 122. When the adjacent roller additional supporting part 14 expands, the roller additional absorbing part 15 contracts to secure a space for the expansion of the roller additional supporting part 14.

[0046] The roller unit 10 according to an embodiment of the present invention may further include a roller discharge unit 16. The roller discharge unit 16 can discharge gas remaining in the roller shaft unit 12 that is not discharged during the vacuum process.

[0047] For example, the roller discharge part 16 may include a first discharge part 161 that discharges gas remaining inside the shaft connecting part 122, and a second discharge part 162 that discharges gas remaining between the shaft connecting part 122 and the roller additional support part 14.

[0048] The first exhaust part 161 may have a hole shape that penetrates the first shaft rotating part 181 and the second shaft rotating part 182. In addition, the first exhaust part 161 may have a hole shape that penetrates the third shaft rotating part 183 and the first shaft coupling part 191. The first exhaust part 161 can exhaust gas inside the shaft connecting part 122.

[0049] The second discharge portion 162 may include a second discharge mounting groove portion 119 that forms a groove for gas movement in the length direction of the shaft mounting portion 129, and a second discharge step groove portion 118 that is formed in the shaft step portion 128 and communicates with the second discharge mounting groove portion 119. A plurality of second discharge portions 162 may be formed in the circumferential direction of the shaft mounting portion 129.

[0050] 3 is a view schematically illustrating a roller maintaining unit according to an embodiment of the present invention. Referring to FIG. 3, the roller unit 10 according to an embodiment of the present invention may further include a roller maintaining unit 17.

[0051] The roller support parts 17 are disposed between the roller additional support parts 14 and can cover the space formed in the shaft connecting part 122 so that the roller additional support parts 14 are in close contact with the roller additional absorbing parts 15. The number of roller additional support parts 14 can be changed depending on the work environment, and if the number of roller additional support parts 14 installed is reduced, the remaining space can be covered by the roller support parts 17.

[0052] That is, when four roller additional support parts 14 are used and then two roller additional support parts 14 are used, the roller support parts 17 corresponding to the two roller additional support parts 14 are attached to the shaft connecting part 122. This allows the roller additional support parts 14 and the roller additional absorbing parts 15 to maintain a tight contact state.

[0053] 1 and 4, the wire deposition apparatus 1 according to the embodiment of the present invention may further include a cooling unit 40.

[0054] The cooling unit 40 can cool the wire 90. The cooling unit 40 can cool the wire 90 heated by the heater unit 20, thereby preventing the roller unit 10 from being heated by the wire 90. The cooling unit 40 can be disposed between the heater unit 20 and the roller unit 10 and can be in direct contact with the wire 90.

[0055] The cooling unit 40 may include a cooling block unit 41 that is fixedly installed in the chamber and contacts the wire 90, and a cooling circulation unit 42 that circulates cooling water through the cooling block unit 41 to cool the cooling block unit 41.

[0056] The cooling unit 40 is additionally disposed between the heater unit 20 and the roller unit 10, which guides the wire 90 that has not passed through the heater unit 20, to cool the wire 90. Meanwhile, the cooling circulation unit 42 supplies additional cooling water to the roller unit 10 to directly cool the roller unit 10.

[0057] 1 and 5, the wire deposition apparatus 1 according to the embodiment of the present invention may further include an adhesion prevention unit 50.

[0058] The adhesion prevention unit 50 covers the outside of the wire 90 except for the deposition space of the wire 90, thereby preventing scattered particles from adhering to the wire 90 outside the deposition space. For example, the adhesion prevention unit 50 may include a prevention box unit 51 having a box shape surrounding the roller unit 10 and the heater unit 20.

[0059] A deposition prevention hole 53 for deposition may be formed at the bottom of the protection box 51, and a pass-through hole 54 for passing the wire 90 may be formed at the top of the protection box 51. The protection box 51 can be disassembled and assembled, and can be fixed to the chamber using a separate support.

[0062] One or more first heat dissipation units 620 may cover the first heater unit 610 and radiate heat so that only the bottom of the first heater unit 610 is open. The first heat dissipation units 620 may cover the first heater unit 610 so that the wire 90 passing under the first heater unit 610 is heated intensively, and may block radiant heat from being transmitted to the periphery of the first heater unit 610.

[0063] 7 is a schematic view of a heater unit according to a second embodiment of the present invention. Referring to FIG. 7, the heater unit 20 according to the second embodiment of the present invention may include a second heater unit 710, a second reflector 720, and a second cooling unit 730.

[0064] The second heater 710 is disposed above the wire 90, and when power is applied, the lamp may be turned on to heat the wire 90. For example, a halogen lamp may be used as the second heater 710. A plurality of second heaters 710 may be disposed above the wire 90 to cross over it.

[0073] The lower heat dissipation unit 840 is disposed between the wire 90 and the cathode unit 30 and can induce heat to be concentrated on the wire 90. As an example, a plurality of lower heat dissipation units 840 may be stacked, and heat may be transferred through the stacked lower heat dissipation units 840. The lower heat dissipation units 840 may prevent radiant heat from the upper heater unit 810 from being transferred to surrounding equipment.

[0074] The lower cooling unit 850 may cool the lower heat dissipation unit 840. For example, heat transferred through the lower heat dissipation unit 840 may be cooled through the lower cooling unit 850.

[0091] When the roller portion 10 is heated by the heater portion 20, the roller shaft portion 12 expands, and the roller absorbing portion 13 supports the expanding roller shaft portion 12 while contracting.

[0092] When the roller additional support part 14 expands, the roller additional absorbing part 15 contracts to support the expanding roller additional support part 14. At this time, the roller shaft part 12 and the roller additional support part 14 surrounding the roller shaft part 12 are each provided with a bearing, thereby ensuring the operability of the wire 90.

[0093] The roller discharge part 16 guides the gas remaining inside the roller part 10 to be discharged stably, and the roller support part 17 can replace the space when the roller additional support part 14 is removed depending on the working environment.

[0094] The heater unit 20 is disposed above the wire 90 and supplies heat to the wire 90 moving below in a concentrated manner, and employs a heat dissipation and reflection structure to prevent radiant heat from being transferred to other equipment.

[0095] The lower heat dissipation units 840 are designed to be stacked in multiple units. The multiple lower heat dissipation units 840 are fixed at their centers, and the length of the center fixing hole 892 formed in the lower heat dissipation units 840 increases from the center to the edge of the lower heat dissipation units 840. Therefore, even if the lower heat dissipation units 840 expand due to high heat from the upper heater unit 810, the installation state can be stably maintained.

[0096] The cooling unit 40 is disposed between the roller unit 10 and the heater unit 20 and comes into direct contact with the heated wire 90 to cool the wire 90, thereby preventing overheating of the roller unit 10 around which the wire 90 is wound. Such cooling units 40 may be disposed on both the left and right sides of the heater unit 20, and cooling water from the cooling unit 40 may pass through the roller unit 10 to directly cool the roller unit 10 as needed.

[0097] The adhesion prevention unit 50 is disposed to surround the entire outside of the wire 90 except for the deposition space of the wire 90. This prevents evaporated particles scattered by the cathode unit 30 from adhering to the wire 90 in areas other than the deposition space.

[0098] In the wire deposition apparatus 1 according to an embodiment of the present invention, a wire 90 is heated by a heater unit 20 and can be deposited while being wound around a plurality of roller units 10 and moved. In addition, the heater unit 20 intensively heats the wire 90 to prevent damage to surrounding equipment, and the adhesion prevention unit 50 partially covers the wire 90 to prevent scattered particles from adhering to the wire 90.

[0099] Although the present invention has been described with reference to the embodiments shown in the drawings, these are merely illustrative, and those skilled in the art will recognize that various modifications and equivalent embodiments are possible. Therefore, the true technical scope of the present invention should be determined by the following claims.
