Description

Technology Field

[0001] The present invention relates to a winding device for an electric vehicle charging cable for winding the charging cable to form it into a spiral coil shape, and the present invention is a research project conducted with the support of the Gyeonggi Economic & Science Promotion Agency (Research Project Name: 2024 Anseong City SME Competitiveness Enhancement Project, Research Task Name: Process Improvement for Productivity Enhancement of Ceiling-mounted Electric Vehicle Charging Systems). Background Technology

[0002] Generally, electric vehicles charge electricity through electric vehicle chargers.

[0003] In the electric vehicle charger, a charging cord is installed at the end of the charging cable, and the charging cord is moved to the part where the electric vehicle's outlet is located to charge it.

[0004] Charging cables are designed to extend a certain length depending on the location of the electric vehicle's outlets. However, as the cables frequently drag on the floor, the outer sheath wears down or gets damaged, leading to electric shock accidents.

[0005] To solve this, the "ceiling-mounted reel device for electric vehicle charging cables" disclosed in Korean Registered Patent Publication No. 10-2635409 (published on February 13, 2024) has been disclosed.

[0006] The above-described conventional ceiling-type reel device for an electric vehicle charging cable is a ceiling-type reel device for an electric vehicle charging cable that winds a charging cable with a charging cord attached to its end so as to lower or raise the charging cord from the upper part of the electric vehicle charging position, and comprises a guide rail installed at the upper part of the charging position, a plurality of rail rollers that move along the guide rail, and a charging cable that is wound in a spiral shape at the lower part of the guide rail, with the upper part connected to each pitch wound on each rail roller, and is unfolded by increasing the pitch interval when lowering the charging cord as if a spring were compressing and expanding, and folded by winding in a spiral shape as the pitch interval decreases again when raising the charging cord.

[0007] This conventional ceiling-mounted reel device for electric vehicle charging cables is installed on the ceiling so that the charging cable does not come into contact with it, which not only prevents wear on the outer sheath, but also allows the charging cable to be formed in a spiral coil shape like a spring, thereby minimizing storage space and enabling easy storage and retrieval.

[0008] However, conventional ceiling-mounted reel devices for electric vehicle charging cables have a problem in that, because they must supply a relatively large amount of electricity, the diameter of the charging cable is large, making it difficult to form it into a spiral coil shape, and it is also difficult to form only the middle part of the charging cable into a coil shape. The problem to be solved

[0009] The present invention has been devised to solve the aforementioned problems, and the objective of the present invention is to provide a winding device for an electric vehicle charging cable that can easily wind a charging cable with a relatively thick diameter into a spiral coil shape by rotating a winding jig by a rotary drive chuck.

[0010] In addition, the present invention aims to provide a winding device for an electric vehicle charging cable that allows the winding jig to be easily attached and detached by configuring the support chuck portion supporting the winding jig to be slidably movable by the chuck rail portion.

[0011] In addition, the present invention aims to provide a winding device for an electric vehicle charging cable that allows the charging cable to be easily fixed and wound by installing a cable clamp on a winding jig, and enables the easy production of a charging cable having only a portion in a coil shape by winding a desired position in the middle part of the charging cable in a coil shape using the cable clamp.

[0012] In addition, the present invention aims to provide a winding device for an electric vehicle charging cable that can easily fix and install the charging cable while installing the cable clamp on the winding jig by configuring a cable fixing part that fixes the charging cable between a first clamp and a second clamp.

[0013] In addition, the present invention aims to provide a winding device for an electric vehicle charging cable that prevents the charging cable fixed to the cable clamp from being severed during winding by configuring a winding direction guide in the cable clamp to prevent excessive bending when the charging cable is wound.

[0014] In addition, the present invention aims to provide a winding device for an electric vehicle charging cable that minimizes installation space by minimizing the overall volume, by installing a supply guide roller between the uncoiler and the winding jig to switch the supply direction of the charging cable, positioning the uncoiler at the bottom, and positioning the winding jig at the top. means of solving the problem

[0015] A winding device for an electric vehicle charging cable according to an embodiment of the present invention for achieving the above-mentioned objective is a winding device for an electric vehicle charging cable that winds the charging cable of an electric vehicle to form a spiral coil shape, and comprises an uncoiler that unwinds and supplies the charging cable while the charging cable is wound; a winding jig that winds the charging cable supplied from the uncoiler into a spiral shape; a rotary drive chuck unit on which one end of the winding jig is mounted and which rotates the winding jig; and a support chuck unit located in a position facing the rotary drive chuck unit and which rotatably supports the other end of the winding jig.

[0016] It includes a chuck rail portion that moves the support chuck portion to be in close contact with or spaced apart from the other end of the winding jig so that the support chuck portion can be detachably attached to the winding jig.

[0017] The above winding jig may include a cable clamp that secures the charging cable supplied from the uncoiler to the winding jig so that the charging cable is wound onto the winding jig as it rotates.

[0018] The above cable clamp may include a first clamp that wraps around a portion of the circumference of the winding jig, a second clamp that wraps around the remaining portion of the winding jig, and a cable fixing part that presses and fixes the charging cable between the first clamp and the second clamp.

[0019] The above cable clamp may include a winding direction guide that guides the bending angle of the charging cable when it is wound to prevent it from being severed while excessively bending at the cable fixing part when the charging cable is wound by the above winding jig.

[0020] It may include a supply guide roller that switches the supply direction of the charging cable from the uncoiler to the position of the winding jig. Effects of the invention

[0021] According to the present invention, a winding jig for winding a charging cable is rotatably installed between a rotary drive chuck and a support chuck, so that a charging cable with a relatively large diameter can be easily wound onto the winding jig.

[0022] In addition, the present invention is configured so that the support chuck can slide along the chuck rail, allowing the winding jig to be easily attached and detached between the rotary drive chuck and the support chuck.

[0023] In addition, the present invention allows the charging cable to be easily fixed to the winding jig by fixing the charging cable to the winding jig by a cable clamp, and allows the charging cable to be easily manufactured in a coil shape only in the middle part of the charging cable by fixing it to the winding jig at a desired location through the cable clamp.

[0024] In addition, the present invention is configured to connect a cable clamp to a winding jig by rotating a first clamp and a second clamp, and forms a cable fixing part that fixes a charging cable between the first clamp and the second clamp, thereby allowing the charging cable to be easily and quickly connected to the winding jig.

[0025] In addition, the present invention can prevent the charging cable from breaking during winding by configuring a winding direction guide in the cable clamp to prevent the fixed charging cable from bending excessively during winding.

[0026] In addition, the present invention can minimize the installation space by reducing the overall volume through the installation of a supply guide roller between the uncoiler and the winding jig, thereby arranging the uncoiler and the winding jig vertically. Brief explanation of the drawing

Specific details for implementing the invention

[0028] Hereinafter, embodiments of the present invention will be described with reference to the attached drawings.

[0029] First, the winding device (100) of the electric vehicle charging cable according to an embodiment of the present invention is intended to form a charging cable having a coiled shape in part or entirely, as disclosed in the "Ceiling-type reel device of an electric vehicle charging cable" of the applicant's Korean Registered Patent Publication No. 10-2635409 (published on February 13, 2024).

[0030] As illustrated in FIGS. 1 to 4, the winding device (100) of an electric vehicle charging cable according to an embodiment of the present invention may include a winding frame (110).

[0031] This winding frame (110) can support each component.

[0032] The winding frame (110) can be configured by forming a plurality of rod-shaped frame members into a square frame shape.

[0033] The winding frame (110) may be equipped with a height-adjustable frame support (111) and wheels (113) to allow the winding device (100) to be easily moved while the height of the frame support (111) is minimized.

[0034] As illustrated in FIGS. 1 and 4, the winding device (100) of an electric vehicle charging cable according to an embodiment of the present invention may include an uncoiler (120).

[0035] This uncoiler (120) can supply a charging cable (300) to be formed into a spiral coil shape.

[0036] In the uncoiler (120), a cable roll on which a charging cable (300) is wound is rotatably installed so as to unwind and supply the wound charging cable (300) as the cable roll rotates, or, as in the embodiment, it may be configured to be installed on an uncoil table (125) that pre-winds the charging cable (300) and unwind and supply it from the uncoil table (125).

[0037] A charging cable (300) may be pre-winded in an uncoil table (125), and the uncoil table (125) may unwind the charging cable (300) and supply it to a winding jig (130) to be described below.

[0038] At this time, when the uncoil table (125) winds the charging cable (300), a fluid may be filled inside the uncoil table (125) to control the rotational speed of the uncoil table (125) so that the charging cable (300) is not supplied loosely by providing a pulling force in the opposite direction to the winding direction of the charging cable (300).

[0039] The uncoil table (125) can be installed on the winding frame (110) so as to be rotatable about a vertical axis, and the uncoil table (125) can be located at the bottom of the winding frame (110).

[0040] As illustrated in FIGS. 2 to 5, the winding device (100) of an electric vehicle charging cable according to an embodiment of the present invention may include a winding jig (130).

[0041] This winding jig (130) can wind the charging cable (300) into a spiral shape.

[0042] The winding jig (130) can be formed in the shape of a pipe, and the charging cable (300) can be wound around the winding jig (130) in the form of a spiral coil from one direction to the other.

[0043] The winding jig (130) can wind a charging cable (300) around its circumference while rotating like a roller by means of the rotary drive chuck (140) described below.

[0044] A cable clamp (133) for fixing the part of the charging cable (300) to be wound can be installed on the winding jig (130) so that the winding jig (130) can rotate and wind the charging cable (300) around the perimeter while fixing the part of the charging cable (300).

[0045] A cable clamp (133) can be installed around the winding jig (130) to fix the starting and ending points of the part to be formed into a coil shape of the charging cable (300).

[0046] For example, the cable clamp (133) can be used to wind one end of the charging cable (300) onto the winding jig (130), and then fix the charging cable (300) to the starting part to be formed into a coil shape with the cable clamp (133). When the charging cable (300) is wound to a preset length, another cable clamp (133) can be fixed to the end part to be formed into a coil shape, and the other end of the remaining charging cable (300) can be wound onto the winding jig (130) located outside the cable clamp (133) to fix the charging cable (300) to be formed into a coil shape so that it does not unravel from the winding jig (130).

[0047] At this time, a charging connector may be pre-installed at the end of the charging cable (300).

[0048] As shown in FIG. 6, the cable clamp (133) can be installed on the winding jig (130) in such a way that the first clamp (134) and the second clamp (135) wrap around the circumference of the winding jig (130).

[0049] For example, the first clamp (134) and the second clamp (135) are configured to be symmetrical to each other in the shape of a half arc, so that when the first clamp wraps around a part of the circumference of the winding jig (130), the second clamp (135) wraps around the remaining circumference of the winding jig (130) and is installed on the winding jig (130) in a manner that is mutually fastened.

[0050] The first clamp (134) and the second clamp (135) are each installed so as to be rotatable by means of a hinge part (133a) at one end facing each other, and a cable fixing part (136) to which a charging cable (300) is fixed can be configured at the other end facing each other.

[0051] The cable fixing part (136) can fix the charging cable (300) by pressing and fixing the charging cable (300) between the other end located opposite to the direction coupled to the hinge part (133a), while the first clamp (134) and the second clamp (135), which are formed in a band shape to wrap around the circumference of the winding jig (130), are positioned facing each other.

[0052] The cable fixing part (136) is formed such that the first pressure fixing part (136a) is bent outward from the winding jig (130) at the end of the first clamp (134) that is opposite to the direction connected by the hinge part (133a) of the first clamp (134) and the second clamp (135), and the second pressure fixing part (136b) is bent outward from the second clamp (135) so that the charging cable (300) can be fixed in a manner such that the part to be wound in the form of a coil of the charging cable (300) is fixed to the first pressure fixing part (136a) and the second pressure fixing part (136b).

[0053] Meanwhile, the cable fixing part (136) may be configured with a clamp fastening part that prevents the first pressure fixing part (136a) and the second pressure fixing part (136b) from separating by mutually connecting the first pressure fixing part (136a) and the second pressure fixing part (136b).

[0054] The clamp fastening part may be configured such that a fastening member (137) is rotatably installed by a hinge pin in either the first pressure fixing part (136a) or the second pressure fixing part (136b), a fastening groove into which the fastening member (137) is fitted is coupled to the other, and a fastening nut (138) is installed at the end of the fastening member (137) to pressurize and fix the fastening member (137) while it is fitted into the fastening groove.

[0055] The clamp fastening member (137) can be fixed by pressing the fastening nut (138) while the fastening member (137) is rotated around the hinge pin and hooked into the fastening groove, thereby fixing the charging cable (300) located between the first pressure fixing part (136a) and the second pressure fixing part (136b), or the fixing of the charging cable (300) can be released by rotating the clamp fastening member (137) to detach from the fastening groove after releasing the pressure of the fastening nut (138).

[0056] At this time, a gap-reinforcing pad (139) may be installed on the inner circumference of the first clamp (134) and the second clamp (135) to compensate for the gap so that the first clamp (134) and the second clamp (135) can be in close contact with the circumference of the winding jig (130), even if the gap between the first pressure fixing part (136a) and the second pressure fixing part (136b) widens or narrows depending on the diameter of the charging cable (300).

[0057] The gap reinforcement pad (139) is formed of a material that can be elastically deformed, so that when, for example, a charging cable (300) with a relatively small diameter is inserted, the gap between the first pressure fixing part (136a) and the second pressure fixing part (136b) narrows, and the gap reinforcement pad (139) is compressed to narrow the gap between the first pressure fixing part (136a) and the second pressure fixing part (136b) and fix it.

[0058] Conversely, when a charging cable (300) with a relatively large diameter is inserted, the gap between the first pressure fixing part (136a) and the second pressure fixing part (136b) widens, and the gap reinforcement pad (139) returns to its initial shape, so that even if the gap between the first pressure fixing part (136a) and the second pressure fixing part (136b) widens, the first clamp (134) and the second clamp (135) can be fixed around the winding jig (130) without detaching.

[0059] Meanwhile, in either the first pressure fixing part (136a) or the second pressure fixing part (136b), a winding direction guide (136c) may be formed to guide the bending direction of the charging cable (300) so as to prevent damage to the charging cable (300) due to excessive bending when winding the charging cable (300) on the winding jig (130).

[0060] The winding direction guide (136c) is formed by being inclined at a preset angle in the radial direction of the winding jig (130) in either the first pressure fixing part (136a) or the second pressure fixing part (136b), so that when the charging cable (300) fixed in the cable fixing part (136) is wound, the winding direction can be guided so that the portion of the charging cable (300) fixed in the cable fixing part (136) is wound at an acute angle with respect to the axial direction of the winding jig (130).

[0061] For example, the charging cable (300) fixed to the cable fixing part (136) is fixed in the same direction as the axial direction of the winding jig (130). When the charging cable (300) is wound while the winding jig (130) rotates, the charging cable (300) is wound while bending at the 90° direction of the winding jig (130), so there is a risk that the charging cable (300) will be severed in the bent part due to excessive bending.

[0062] Accordingly, the winding direction guide (136c) guides the direction of bending so that the charging cable (300) fixed to the cable fixing part (136) at the first pressure fixing part (136a) or the second pressure fixing part (136b) bends at an acute angle, thereby preventing the charging cable (300) from being severed due to excessive bending when winding.

[0063] A pair of cable clamps (133) are installed on a winding jig (130), and one is fixed at the position where winding begins in the middle part of the charging cable (300). When the cable is wound for a preset number of turns or length, the other is installed at the position where winding is finished, thereby securing the part of the charging cable (300) to be formed into a coil shape so that it does not come loose from the winding jig (130).

[0064] As illustrated in FIGS. 1 to 5, the winding device (100) of an electric vehicle charging cable according to an embodiment of the present invention may include a rotary drive chuck part (140), a support chuck part (150), and a chuck rail part (155).

[0065] The rotary drive chuck (140) can provide power to rotate the winding jig (130), and the rotary drive chuck (140) can be located on one side of the upper part of the winding frame (110).

[0066] The rotary drive chuck unit (140) is equipped with a rotary chuck (141) to which one end of the winding jig (130) is detachably connected, and the rotary chuck (141) rotates by the power of the chuck drive motor (143) and can rotate the winding jig (130) connected to the rotary chuck (141).

[0067] Of course, the chuck drive motor (143) and the rotary chuck (141) can be rotated by transmitting the power of the chuck drive motor (143) to the rotary chuck (141) through a power transmission member such as a belt or chain.

[0068] A plurality of gripping members (141a) capable of supporting the inner or outer circumference of the winding jig (130) are installed in the rotating chuck (141), so that the gripping members (141a) move simultaneously in the radial direction of the winding jig (130) to grip and fix the winding jig (130), or the fixing of the winding jig (130) can be released by moving away in the radial direction while the gripping members (141a) are gripping the winding jig (130).

[0069] A plurality of gripping members (141a) installed on the rotating chuck (141) can move inward or outward in the radial direction of the winding jig (130) simultaneously by means of a gear connection.

[0070] The support chuck (150) may be positioned apart from the rotational drive chuck (140) in the winding frame (110), and the support chuck (150) may rotatably support the other end of the winding jig (130) that rotates by the rotational chuck (141).

[0071] The support chuck (150) is equipped with a conical chuck roller (151) so that the chuck roller (151) is partially inserted into the other end of the winding jig (130) and comes into close contact, thereby enabling the winding jig (130) to be rotatably supported by the rotating chuck (141).

[0072] A support roller (153) may be installed in the portion where the support chuck (150) is located between the support chuck (150) and the rotary drive chuck (140) to support the circumference of the winding jig (130) supported by the support chuck (150), thereby preventing the winding jig (130) from sagging downwards due to the load of the charging cable (300) wound on the winding jig (130), and at the same time, to maintain the state even if the fixation by the support chuck (150) is released at the other end of the winding jig (130).

[0073] A pair of support rollers (153) are spaced apart, and a portion of the winding jig (130) located near the upper end of the support rollers (153) can be positioned by being seated on the upper end of the pair of support rollers (153).

[0074] The support chuck (150) can slide in the winding frame (110) toward the other end of the winding jig (130) by means of the chuck rail (155) to grip the winding jig (130), or slide in the opposite direction of the winding jig (130) while gripping the winding jig (130) to release the gripping of the winding jig (130).

[0075] Of course, the chuck rail part (155) can position the support chuck part (150) in correspondence with the length of the winding jig (130) as the support chuck part (150) slides, and the chuck rail part (155) can slide in the longitudinal direction of the winding jig (130) at the other end of the winding jig (130).

[0076] The chuck rail portion (155) includes a chuck moving mechanism (156) and can grip the winding jig (130) or release the gripping of the winding jig (130) by moving the support chuck portion (150) along the longitudinal direction of the winding jig (130) by the power of the chuck moving mechanism (156).

[0077] The chuck movement mechanism (156) is implemented with a pneumatic or hydraulic cylinder, and the support chuck part (150) is coupled to the cylinder shaft that moves in and out, so that the support chuck part (150) can slide along the chuck rail part (155).

[0078] As illustrated in FIGS. 1 and 2, the winding device (100) of an electric vehicle charging cable according to an embodiment of the present invention may include a supply guide roller (160) or a winding controller (170).

[0079] The supply guide roller (160) is positioned between the uncoiler (120) and the winding jig (130) mounted on the rotary drive chuck (140), so that the charging cable (300) supplied from the uncoiler (120) can be supplied by changing its direction to the direction in which the winding jig (130) is located.

[0080] The supply guide roller (160) can be installed on the winding frame (110), and the supply guide roller (160) can be installed at a position on the winding frame (110) that intersects with the vertical lower part of the winding jig (130) while facing the uncoiler (120).

[0081] For example, the supply guide roller (160) is installed at a position on the winding frame (110) that is horizontally facing the uncoiler (120) located at the bottom of the winding frame (110) and intersects the vertical lower portion of the winding jig (130) located at the top of the winding frame (110), so that the charging cable (300) supplied from the uncoiler (120) moves horizontally to the portion where the winding jig (130) is located, and then is supplied by changing direction to the position of the winding jig (130) located at the top through the supply guide roller (160).

[0082] A pair of supply guide rollers (160) are arranged vertically, and the charging cable (300) supplied from the uncoiler (120) can be supplied to the part where the winding jig (110) is located through the space between the pair of supply guide rollers (160).

[0083] In another example, the supply guide rollers (160) may be arranged in multiple numbers spaced apart vertically, and the charging cable (300) may be configured to pass through all of the spaced supply guide rollers (160) and be supplied from the uncoiler (120) to the winding jig (130).

[0084] Here, the supply guide rollers (160), which are composed of multiple rollers, apply tension to the charging cable (300) supplied to the winding jig (130) in the opposite direction of supply, thereby preventing the charging cable (300) from being wound loosely when winding the charging cable (300) on the winding jig (130).

[0085] On the other hand, when configured so that the charging cable (300) passes between a pair of supply guide rollers (160) as in the embodiment, when winding the charging cable (300) onto the winding jig (110), the operator can prevent the charging cable (300) from being wound loosely by pulling in the opposite direction to the winding direction to maintain tension while winding the charging cable (300) onto the winding jig (110).

[0086] The winding controller (170) can control the rotational speed or number of windings of the rotary drive chuck (140) or control the chuck movement mechanism (156) of the support chuck (150) to control the attachment and detachment of the winding jig (130) by the support chuck (150).

[0087] The winding controller (170) may be configured with an operating part so that it can be operated by an operator.

[0088] The control unit may also be implemented as a control button or control pedal for controlling the number of windings according to the rotation speed of the rotating chuck (141), the winding speed of the rotating chuck (141), and the fixing and unlocking of the support chuck unit (150).

[0089] In addition, the number of windings and winding speed may be pre-set and stored in the winding controller (170) through the control unit.

[0091] Hereinafter, embodiments of the present invention will be described with reference to the attached drawings.

[0092] The winding device (100) of an electric vehicle charging cable according to an embodiment of the present invention is configured such that an uncoiler (120) for supplying a charging cable (300) is installed at the lower part of a winding frame (110), and the uncoiler (120) is configured to pre-wind a charging cable (300) to be wound on an uncoil table (125) that is rotatably installed, or to install a cable roll on which a charging cable (300) is wound.

[0093] Meanwhile, on one side of the upper part of the winding frame (110), a rotary drive chuck (140) for rotating the winding jig (130) to wind the charging cable (300) is configured, and on the other side facing the rotary drive chuck (140), a support chuck (150) for supporting the winding jig (130) is located.

[0094] The rotary drive chuck unit (140) rotates the rotary chuck (141) by means of a chuck drive motor (143), and a plurality of gripping members (141a) are installed radially on the rotary chuck (141), so that as the gripping members move in the radial direction, they grip one end of the winding jig (130) and rotate it.

[0095] A chuck roller (151) that supports the other end of the winding jig (130) while being rotatable may be installed in the support chuck portion (150), and a support roller (153) that supports the lower end of the winding jig (130) when the support chuck portion (150) is not supporting the winding jig (130) is installed in the portion where the end of the winding jig (130) is located near the chuck roller (151).

[0096] The support chuck (150) can be installed to slide toward the other end of the winding jig (130) by means of a chuck rail (155), and the chuck rail (155) includes a chuck moving mechanism (156) to support the support chuck (150) by pressing it against the other end of the winding jig (130), or to release the fixation by the support chuck (150) by separating the support chuck (150) from the other end of the winding jig (130).

[0097] A cable clamp (133) is installed in the winding jig (130) to fix the part to be formed into a coil shape of the charging cable (300), and the cable clamp (133) is configured such that a first clamp (134) and a second clamp (135) wrap around the circumference of the winding jig (130), and one end of the first clamp (134) and the second clamp (135) is connected by a hinge part (133a) so that they can rotate relative to each other.

[0098] At the other end of the first clamp (134) and the second clamp (135), a cable fixing part (136) is configured to press and fix the charging cable (300) between them, and the cable fixing part (136) is configured to have a fastening member (137) for connecting the first clamp (134) and the second clamp (135) to each other, which is tightened by a fastening nut (138) to fix or release the charging cable (300).

[0099] And, the first clamp (134) and the second clamp (135) are configured with a winding direction guide (136c) to prevent the charging cable (300) fixed to the cable fixing part (136) from being wound while excessively bent.

[0100] A supply guide roller (160) is installed on the winding frame (110) to divert the direction of the charging cable (300) supplied from the uncoiler (120) to the winding jig (130) located at the top.

[0101] Meanwhile, a winding controller (170) is installed in the winding frame (110) to control the number of windings or winding speed and the operation of the support chuck (150), and the winding controller (170) may be configured with an operating part so that a worker can operate it.

[0102] The winding device (100) of the electric vehicle charging cable according to the embodiment of the present invention configured as described above positions the end of the charging cable (300) wound on the uncoiler (120) on the upper part of the winding frame (110) via the supply guide roller (160).

[0103] Then, one end of the winding jig (130) is fixed by moving the gripping member (141a) to the rotating chuck (141) of the rotary drive chuck (140), and the other end of the winding jig (130) is positioned on the upper part of the support roller (153).

[0104] When the winding jig (130) is fixed to the rotary chuck (141), the operator operates the support chuck (150) to support the other end of the winding jig (130) through the control part of the winding controller (170).

[0105] When a worker operates the support chuck (150), the support chuck (150) moves along the chuck rail (155) by the chuck moving mechanism (156), and the winding jig (130) is fixed in such a way that the chuck roller (151) is inserted into the other end of the winding jig (130).

[0106] When the winding jig (130) is fixed, the charging cable (300) is wound onto the winding jig (130) up to the portion to be formed into a coil shape of the charging cable (300), and when the starting position to be formed into a coil shape of the charging cable (300) is located on the winding jig (130), the cable clamp (133) is attached to the starting position and the charging cable (300) is fixed to the winding jig (130) through the cable fixing part (136).

[0107] When the charging cable (300) is fixed to the winding jig (130), the operator performs winding by rotating the rotary drive chuck (140) through the winding controller (170), and the operator provides tension by pulling the charging cable (300) in the opposite direction of winding to prevent the charging cable (300) from being loosely wound on the winding jig (130).

[0108] When the winding jig (130) is fixed to the cable fixing part (136), the operator performs winding by rotating the rotary drive chuck part (140) through the winding controller (170).

[0109] The winding controller (170) has the number of windings and winding speed set in advance, and the rotating chuck (141) rotates according to the set number of windings and winding speed in accordance with the operator's operation, thereby winding the portion of the charging cable (300) to be formed into a coil shape.

[0110] At this time, the number of windings and winding speed are pre-set in the winding controller (170), and the rotating chuck (141) rotates according to the pre-set number of windings and winding speed in accordance with the operator's operation.

[0111] Meanwhile, when the rotating chuck (141) rotates, the winding jig (130) rotates and the charging cable (300) is wound. In the initial stage of winding the charging cable (300), the charging cable (300) is guided by the winding direction guide (136c) to prevent excessive bending in the winding direction, thereby preventing the charging cable (300) from breaking due to excessive bending during the initial winding.

[0112] When the rotating chuck (141) rotates at a preset number of turns and winding speed and the winding is completed, another cable clamp (133), similar to the cable clamp (133) previously installed, is installed on the part of the charging cable (300) where the winding is completed, and the charging cable (300) is fixed to the winding jig (130), and then the charging cable (300) is cut.

[0113] When the rotating chuck (141) rotates at a preset number of windings and winding speed and winding is completed, another cable clamp (133) is installed at the end of the wound charging cable (300), similar to the cable clamp (133) that was previously installed, to fix the charging cable (300) to the winding jig (130), and then the remaining part of the charging cable (300) is also wound onto the winding jig (130).

[0114] When all the charging cables (300) are wound onto the winding jig (130), the operator releases the fixation of the winding jig (130) through the control unit of the winding controller (170). When the fixation of the winding jig (130) is released, the chuck moving mechanism (156) separates the support chuck part (150) from the other end of the winding jig (130) along the chuck rail part (155).

[0115] When the support chuck (150) is separated from the end of the winding jig (130) by the chuck moving mechanism (156), the gripping member (141a) is moved in the circumferential direction from the rotating chuck (141) to release the fixation of one end of the winding jig (130), and then the winding jig (130) is separated from the winding frame (110), thereby ending the winding of the charging cable (300) on the winding jig (130).

[0116] When the winding of the charging cable (300) is finished, a new winding jig (130) is installed again between the rotary drive chuck (140) and the support chuck (150), and then the charging cable (300) can be continuously wound repeatedly on multiple winding jigs (130) in the same manner as above.

[0118] Accordingly, the winding device (100) of an electric vehicle charging cable according to an embodiment of the present invention can automatically and easily wind the charging cable (300) into a spiral coil shape on the winding jig (130) by rotating the winding jig (130) through the rotary drive chuck (140).

[0119] In addition, the present invention allows the winding jig (130) to be easily detached by moving the support chuck part (150), which fixes the other end of the winding jig (130), through the chuck rail part (155).

[0120] In addition, the present invention allows the charging cable (300) to be easily wound onto the winding jig (130) by fixing it to the winding jig (130) by means of a cable clamp (133) for fixing the charging cable (300) to the winding jig (130), and also allows the charging cable (300) having only a part in a coil shape to be easily manufactured by fixing the cable clamp (133) to a desired position of the charging cable (300) to be formed in a coil shape.

[0121] In addition, the present invention can prevent the charging cable (300) from being severed due to excessive bending when winding the charging cable (300) through the cable clamp (133) by configuring a winding direction guide (136c) in the cable clamp (133).

[0122] In addition, the present invention allows for easy supply of a charging cable (300) from an uncoiler (120) located at the bottom to a winding jig (130) located at the top by installing a supply guide roller (160) on a winding frame (110), and the size of the equipment can be minimized by arranging the uncoiler (120) and the winding jig (130) vertically.
