Description

Technology Field

[0001] The present invention relates to a bobbin device for a metal wire for graphene deposition, and more specifically, to a bobbin device for a metal wire for graphene deposition that can deposit graphene on a metal wire by winding the metal wire while unfolding it evenly and then feeding it into a deposition device. Background Technology

[0002] Graphene is a thin film material in which carbon atoms are arranged in two dimensions. It is known to have very high electrical conductivity because the electric charge within it acts as a zero effective mass particle, as well as high thermal conductivity and elasticity. Additionally, results have been reported that graphene is advantageous for high-frequency transmission signals without noise influence, even at narrow linewidths.

[0003] Graphene can be manufactured in the form of a wire as well as a flat plate, and has excellent shielding performance against high frequencies, etc., so it can be applied to wiring of circuit boards that are essential for electrical and electronic devices, transparent displays, flexible displays, audio devices, etc.

[0004] Published Patent No. 10-2024-0106062 (Graphene deposition apparatus for metal wires, published July 8, 2024) describes technology for a graphene deposition apparatus for metal wires. The technology disclosed above is a graphene deposition apparatus for metal wires, wherein a deposition apparatus capable of manufacturing metal wires roll-to-roll is disclosed.

[0005] However, since the above technology deposits graphene onto wires using a roll-to-roll method, there was a limit to the amount of wire on which graphene could be deposited. Additionally, there was a problem in that the number of rollers required to be installed increased because rollers had to be provided according to the number of strands of the wire to be deposited. Furthermore, there was also a problem in that the deposition device had to be enlarged due to the increased number of rollers. Prior art literature

Specific details for implementing the invention

[0023] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the embodiments described below are merely intended to provide a detailed description sufficient for a person skilled in the art to easily practice the invention, and do not imply that the scope of protection of the present invention is limited thereby. Furthermore, in describing various embodiments of the present invention, the same reference numerals will be used for components having the same technical features.

[0025] FIG. 1 is a perspective view of a bobbin device (1) for a metal wire for graphene deposition according to an embodiment of the present invention. As shown in the drawing, the bobbin device (1) includes a vertical body part (30) and a horizontal body part (40). Specifically, it is possible to wind a metal wire (110) with the configuration of the vertical body part (30) and the horizontal body part (40). However, for efficient winding, the vertical body part (30) is installed to be supported by a support (20) installed on the upper side of the base frame (10). The base frame (10) is composed of a vertical frame (11) and a horizontal frame (12). A caster (13) for movement may be provided on the bottom surface of the base frame (10). A roller mounting part (50) on which a metal wire is wound may be provided on the front of the base frame (10). The roller mounting section (50) is composed of a pair of roller supports (51) and a roller mounting groove (52) formed on the upper end of the roller supports (51). Additionally, a vertical body mounting section (20) is further provided on the base frame (10). The vertical body mounting section (20) is composed of a vertical body support (21) and a support shaft groove (22) formed on the upper end of the vertical body support (21). A vertical body section (30) is mounted on the vertical body mounting section (20), and a horizontal body section (40) is provided on the inner side of the vertical body section (30). The vertical body section (30) is configured to include a vertical frame (33) that opens forward and backward, and a vertical wire seating section (34) provided on the vertical frame (33).

[0026] The vertical body part (30) is described in detail with reference to FIGS. 2 and FIGS. 3. In the vertical body part (30), a pair of support shafts (31) are installed on both sides of the center of the vertical frame (33), and a rotary drive unit (32) is connected to the support shafts (31). The rotary drive unit (32) is configured to drive the horizontal body part (40) in rotation. Additionally, the rotary drive unit (32) is configured to drive the entire vertical body part (30) and the horizontal body part (40) when the horizontal body part (40) is fixed to the vertical body part (30) by a stopper (46). Specifically, the rotary drive unit (32) is composed of a pair of drive shafts (321) each installed on the inner side of the support shaft (31) to drive the horizontal body unit (40) in rotation, and a handle (322) installed on one of the pair of drive shafts (321) and equipped with a handle (3221). The vertical frame (33) is composed of a pair of side frames (331: 331a, 331b) on which the support shaft (31) is each installed, an upper frame (332) connecting the upper ends of the side frames (331), and a lower frame (333) connecting the lower ends of the side frames (331). A vertical wire mounting unit (34) is mounted on the inner side of the pair of side frames (331). The vertical wire mounting portion (34) consists of an upper wire mounting portion (35) mounted on the inner upper part of the side frame (331) and a lower wire mounting portion (36) mounted on the inner lower part of the side frame (331).

[0027] Referring to FIGS. 3 and FIGS. 4, the upper wire mounting portion (35) and the lower wire mounting portion (36), which are vertical wire mounting portions (34), will be described in detail.

[0028] As illustrated in FIGS. 3 and 4, the upper wire seating portion (35) is composed of an upper winding portion (351) and a pair of upper joint portions (353). The upper winding portion (351) is composed of an upper winding bar (3511) on which a metal wire (110) is wound on the upper surface, and a pair of upper joint holes (3512: 3512a, 3512b) formed at both ends of the upper winding bar (3511). The upper joint portion (353) is configured to fix both sides of the upper winding portion (351) to the side frame (331). The upper joint portions (353: 353a, 353b) are formed as a pair and are fastened to the upper joint holes (3512) on both sides to fix the upper wire seating portion (35) to the side frame (331). The upper surface of the upper winding bar (3511) is formed in an arc shape so that the wire (110) being wound is not damaged. Additionally, the upper wire seating portion (35) is further provided with a plurality of upper stacked winding portions (352) on the upper winding portion (351). The upper stacked winding portion (352) consists of an upper stacked winding bar (3521) and an upper fixed fastening portion (3522). The upper stacked winding bar (3521) has an upper surface formed in an arc shape, similar to the upper winding bar (3511). Furthermore, the upper stacked winding portions (352: 352a, 352b, 352c, 352d) are composed of multiple units, with the width increasing from the bottom to the top. Because the width is configured to increase, the wire (110) being wound on the winding bar is maintained at a constant distance from front to back, so that interference does not occur between them.The upper joint portion (353: 353a, 353b) is composed of an upper joint plate (3531: 3531a, 3531b) having a plurality of bolt holes formed therein, an upper spring first support member (3532: 3532a, 3532b) mounted on the upper joint plate (3531), an upper spring second support member (3533: 3533a, 3533b) mounted on the upper end of the side frame (331), an upper spring (3534: 3534a, 3534b) connected to the upper spring first support member (3532) and the upper spring second support member (3533), and a plurality of upper bolts (3535: 3535a, 3535b) for fastening the upper joint plate (3531) to the side frame (331) and the upper joint hole portion (3512). The upper joint portion (353) is configured to allow the wire (110) to be stretched taut after the wire (110) is wound onto the winding bar. Since upper springs (3534) are provided on both sides, after the wire (110) is wound onto the winding bar, the upper wire seating portion (35) moves upward by the upper springs (3534), and accordingly, the wire (110) wound onto the winding bar can be stretched taut. When a portion of the upper bolt (3535) of the upper joint plate (3531) is loosened and only the remaining upper bolt (3535) fastened to the upper joint hole portion (3512) is fastened, the fastening force of the bolt is reduced, and the upper wire seating portion (35) moves upward by the elastic force of the upper spring (3534). If necessary, the bolt fastened to the upper joint hole (3512) is also loosened so that the upper wire seating portion (35) can be moved upward. Accordingly, an upper guide hole (3311: 3311a, 3311b) of a certain length is formed in the side frame (331) so that the upper bolt (3535) fastened to the upper joint hole (3512) can be moved.

[0029] As illustrated in FIGS. 3 and 4, the lower wire seating portion (36) is also composed of a lower winding portion (361) and a pair of lower joint portions (363), and is formed symmetrically with respect to the upper wire seating portion (35). Specifically, the lower winding portion (361) is composed of a lower winding bar (3611) on which a metal wire (110) is wound around the lower surface, and a pair of lower joint holes (3612: 3612a, 3612b) formed at both ends of the lower winding bar (3611). The lower joint portion (363) is configured to fix both sides of the lower winding portion (361) to the side frame (331). The lower joint portions (363: 363a, 363b) are formed as a pair and are fastened to the lower joint holes (3612) on both sides to fix the lower wire seating portion (36) to the side frame (331). The lower winding bar (3611), like the upper winding bar (3511), is formed in an arc shape so that the wire (110) wound on the lower surface is not damaged. Additionally, the lower wire seating portion (36), like the upper wire seating portion (35), is further provided with a plurality of lower stacked winding portions (362) at the bottom of the lower winding portion (361). The lower stacked winding portion (362) consists of a lower stacked winding bar (3621) and a lower fixed fastening portion (3622). The lower stacked winding bar (3621), like the lower winding bar (3611), has a lower surface formed in an arc shape. Additionally, the lower stacked winding portions (362: 362a, 362b, 362c, 362d) are composed of multiple units, and their width increases from the top to the bottom. Because it is configured to be wider, the wire (110) wound on the winding bar is maintained at a constant distance from front to back so that there is no interference between them.The lower joint portion (363: 363a, 363b) is composed of a lower joint plate (3631: 3631a, 3631b) having a plurality of bolt holes formed therein, a lower spring first support member (3632: 3632a, 3632b) mounted on the lower joint plate (3631), a lower spring second support member (3633: 3633a, 3633b) mounted on the lower end of the side frame (331), a lower spring (3634: 3634a, 3634b) connected to the lower spring first support member (3632) and the lower spring second support member (363), and a plurality of lower bolts (3635: 3635a, 3635b) for fastening the lower joint plate (3631) to the side frame (331) and the lower joint hole portion (3612). The lower joint portion (363) is configured to allow the wire (110) to be stretched taut after the wire (110) is wound onto the winding bar together with the upper joint portion (353). Since lower springs (3634) are provided on both sides, after the wire (110) is wound onto the winding bar, the lower wire seating portion (36) moves upward by the lower springs (3634), and accordingly, the wire (110) wound onto the winding bar can be stretched taut. When a portion of the lower bolt (3635) of the lower joint plate (3631) is loosened and only the remaining lower bolt (3635) fastened to the lower joint hole portion (3612) is fastened, the fastening force of the bolt is reduced, and the lower wire seating portion (36) moves downward by the elastic force of the lower spring (3634). If necessary, the bolt fastened to the lower joint hole (3612) is also loosened so that the lower wire seating portion (36) can be moved downward. Accordingly, a lower guide hole (3312: 3312a, 3312b) of a certain length is formed in the side frame (331) so that the lower bolt (3635) fastened to the lower joint hole (3612) can be moved.

[0030] In addition, as shown in FIG. 3, a footrest (37: 37a, 37b) is fixedly mounted at the bottom of the side frame (331) by footrest bolts (371: 371a, 371b) so that the vertical body part (30) can stand vertically.

[0031] FIGS. 5 and FIGS. 6 illustrate a horizontal body portion (40). As shown in the drawings, the horizontal body portion (40) is provided with a pair of rotation shafts (41: 41a, 41b) connected to a drive shaft (321), and the rotation shafts (41) are mounted on a horizontal frame (42), and a horizontal wire seating portion (43) is mounted on the horizontal frame (42). Specifically, the rotation shafts (41) are each mounted on the inner side of the side frame (331) so that they can be rotated in connection with the drive shaft (321). In addition, one side of the rotation shaft (41) is connected to the drive shaft on which the handle (322) is mounted, and rotates together with the rotation of the handle (322). In the drawings, the rotation shaft (41b) of the other side body (421b) is connected to the drive shaft (321b) on which the handle (322) is mounted. The horizontal frame (42) is composed of a pair of side bodies (421: 421a, 421b) each having a rotation axis (41) mounted thereon, a front body (422) connecting the front of the side body (421), and a rear body (423) connecting the rear of the side body (421). The horizontal wire mounting portion (43) is composed of a front wire mounting portion (44) and a rear wire mounting portion (45). The front wire mounting portion (44) is mounted on the inner front end of the side body (421). Additionally, the rear wire mounting portion (45) is mounted on the inner rear end of the side body (421). The front wire mounting portion (44) consists of a front winding bar (441) on which a metal wire (110) is wound on the front surface, and a pair of front joint bolts (442: 442a, 442b) for fixing both sides of the front winding bar (441) to the side body (421). The front wire mounting portion (44) can be rotated or fixed by the front joint bolts (442). After winding the metal wire (110) onto the winding bar, the horizontal body portion (40) is rotated. After the horizontal body portion (40) is rotated, the front wire mounting portion (44) is rotated so that the wire (110) maintains a constant distance from the front to the back.Additionally, the front wire mounting portion (44) may further be equipped with a plurality of front stacked winding bars (443: 443a, 443b, 443c, 443d) in front of the front winding bar (441). The wire (110) can be maintained at a constant interval in the front and rear on the front stacked winding bar (443), thereby enabling a large amount of wire to be deposited at once.

[0032] Additionally, the rear wire mounting portion (45) consists of a rear winding bar (451) on which a metal wire (110) is wound on the rear side, and a pair of rear joint bolts (452: 452a, 452b) for fixing both sides of the rear winding bar (451) to the side body (421). The rear wire mounting portion (45) can be rotated or fixed by the rear joint bolts (452). After winding the metal wire (110) onto the winding bar, the horizontal body portion (40) is rotated, and after the horizontal body portion (40) is rotated, the rear wire mounting portion (45) is rotated so that the wire (110) maintains a constant distance from the front to the back. Additionally, the rear wire mounting portion (45) may further be equipped with a plurality of rear stacked winding bars (453: 453a, 453b, 453c, 453d) at the rear of the rear winding bar (451). The wire (110) can be maintained at a constant distance from front to back on the rear stacked winding bar (453) together with the front stacked winding bar (443), thereby enabling a large amount of wire to be deposited at once.

[0033] Additionally, since the horizontal wire mounting portion (43) must wind the wire (110) while maintaining a '+' shape together with the vertical wire mounting portion (34), the horizontal body portion (40) is fixed to the side body portions (421) on both sides using stoppers (46: 46a, 46b) so that the horizontal body portion (40) can be maintained in a '+' shape on the vertical body portion (30). Accordingly, rotation of only the side body portions (421) is prevented. The stopper (46) uses a bolt, and the stopper (46) may be provided on only one side, and rotation of only the horizontal body portion (40) is prevented by the stopper (46), and it rotates together with the vertical body portion (30).

[0034] FIGS. 7 to 9 illustrate winding a metal wire (110). As shown in FIG. 7, a metal wire roller (100) is mounted on a roller mounting part (50). The metal wire (110) is wound sequentially from the inside of the winding bar on the roller (100). As shown in FIG. 7, the vertical body part (30) and the horizontal body part (40) are fixed with a stopper (46) to form a '+' shape, and the upper frame (332) and the lower frame (333) are removed. Then, the vertical body part (30) and the horizontal body part (40) are rotated together with a handle (3221). As the vertical body part (30) and the horizontal body part (40) rotate, the metal wire (110) is first wound around the upper winding bar (3511), the lower winding bar (3611), the front winding bar (441), and the rear winding bar (451), and the metal wire (110) is wound in a line at regular intervals so as not to overlap. When the winding of the lowest winding bar (3511, 3611, 441, 451) is completed, the upper stacked winding bar (3521) is connected to the upper winding bar (3511), the lower stacked winding bar (3621) is connected to the lower winding bar (3611), the front stacked winding bar (443) is connected to the front winding bar (441), and the rear stacked winding bar (453) is connected to the rear winding bar (451). When the connection is complete, the metal wire (110) is wound onto the upper stacked winding bar (3521), the lower stacked winding bar (3621), the front stacked winding bar (443), and the rear stacked winding bar (453). This process is repeated sequentially to wind the metal wire (110). FIG. 8 illustrates the state in which the metal wire (110) is wound onto the vertical body portion (30) and the horizontal body portion (40). Although only one wire is shown in the drawing, additional metal wires (110) wound at regular intervals forward and backward by the stacked winding bar can be formed as shown in FIG. 9.FIG. 9 illustrates that after the winding of the metal wire (110) is completed, the stopper (46) of the horizontal body part (40) is released and the horizontal body part (40) is rotated so that the horizontal body part (40) is positioned in an upper and lower alignment with the vertical body part (30). FIG. 9 also illustrates that when the horizontal body part (40) is rotated, the front wire seating part (44) and the rear wire seating part (45) are also rotated, respectively, so that the metal wire (110) connected vertically maintains a constant distance in the front and back directions. When the horizontal body part (40) is in an upper and lower alignment with the vertical body part (30), the stopper (46) is tightened again to fix the position of the horizontal body part (40). Additionally, when the horizontal body part (40) is rotated and positioned in an upper and lower alignment with the vertical body part (30), the metal wire (110) becomes loose. Since damage to the wire may occur if the metal wire (110) becomes loose, the upper wire seating portion (35) is moved to the top of the side frame (331) by the upper spring (3534) of the upper joint portion (353), and the lower wire seating portion (36) is moved to the bottom of the side frame (331) by the lower spring (3635) of the lower joint portion (363). By loosening the upper bolt (3535) and the lower bolt (3635), the upper wire seating portion (35) and the lower wire seating portion (36) are moved respectively so that the metal wire (110) can be tightened. The upper winding bar (351) and the upper stacked winding bar (352) become wider as they go from bottom to top, and likewise, the lower winding bar (361) and the lower stacked winding bar (362) become wider as they go from top to bottom. Accordingly, the wires (110) wound back and forth maintain a constant distance from each other so as not to interfere.

[0035] FIG. 10 illustrates a configuration that enters a deposition device (not shown). Since it is advantageous for the part to be inserted into the deposition device to have a small volume, in the case of the vertical body part (30), only the vertical frame (33), the upper wire mounting part (35), and the lower wire mounting part (36) are left, and the rest is separated. Since the horizontal body part (40) is located inside the vertical body part (30), it is inserted as is. Accordingly, a part of the vertical body part (30) and the horizontal body part (40) are inserted into the deposition device, and graphene can be deposited on a large amount of metal wire (110) inserted. Therefore, it has the advantage of increasing production efficiency.

[0037] Although embodiments of the present invention have been described above, it is understood that those skilled in the art can make various modifications without departing from the scope of the claims of the present invention. Explanation of the symbols
