[0025] Referring to FIGS. 1 to 4, the outer ring fixing device (100) of the present invention includes a frame portion (110); and a plurality of grip portions (120).

[0026] The coil (1) is cylindrical in shape and consists of a curved side surface (a) and a circular bottom surface (b) located on both sides of the side surface (a). The outer ring (10) is a member mounted on the edge portion of the coil (1) and consists of a curved surface (11) and a flat surface (12) bent from the curved surface (11).

[0027] The outer ring fixing device (100) can position the outer ring (10) at the edge of the coil (1) by moving the outer ring (10) to the edge portion of the coil (1) to adjust the diameter of the outer ring (10) so that the inner surface of the curved surface (11) contacts the outer circumference of the side surface (a) of the edge portion of the coil (1), and the outer ring (10) contacts the flat surface (12) so that the inner surface of the flat surface (12) contacts the flat surface (b) of the edge portion of the coil (1).

[0028] To this end, the outer ring fixing device (100) can be provided with an outer ring (hereinafter referred to as "unfixed outer ring (20)" in which one end and the other end of the outer ring (10) are not fixed to each other, and can be fixed to the edge portion of the coil.

[0032] One end of each rail (111) can be fixed to the center frame (112) so that the plurality of rails (111) are arranged radially on the center frame (112).

[0033] In FIG. 3, the plurality of rails (111) are arranged radially at 60° intervals from each other, but the number of the plurality of rails (111) can be three or more at a set angle.

[0034] A plurality of grip portions (120) are installed on each of the above rails (111) so as to be reciprocally movable.

[0035] The above plurality of grip portions (120) can move in the forward and backward directions on each rail (111) while the unfixed outer ring (20) is fixed.

[0036] The above plurality of grip portions (120) can adjust the diameter of the unfixed outer ring (20).

[0037] Accordingly, the outer ring fixing device (100) of the present invention can move the unfixed outer ring (20) to the edge portion of the coil (1) and adjust the diameter of the unfixed outer ring (20) to correspond to the diameter of the coil (1) so that the unfixed outer ring (20) can be installed on the edge of the coil (1).

[0038] Specifically, when the plurality of grip portions (120) move closer to the center frame (112), the diameter of the unfixed outer ring (20) decreases, and when the plurality of grip portions (120) move away from the center frame (112), the diameter of the unfixed outer ring (20) increases.

[0040] FIG. 5 is an exploded perspective view of the pressure grip portion of the outer ring fixing device of FIG. 3, FIG. 6 is an exploded perspective view of the roller grip portion of the outer ring fixing device of FIG. 3, and FIG. 7 is a drawing for explaining the operation of the roller grip portion of FIG. 6.

[0041] Referring further to FIGS. 5 to 7b, the plurality of grip portions (120) may include one or more pressure grip portions (121) and a plurality of roller grip portions (122).

[0042] The above pressure grip portion (121) is installed to be movable in the forward and backward directions on each rail (111).

[0043] The above pressure grip portion (121) can press the curved surface (11) after transferring the unfixed outer ring (20) to the edge portion of the coil (1), so that the inner surface of the curved surface (11) comes into contact with the outer surface of the side surface (a) of the edge portion of the coil (1).

[0044] Each of the above pressure grip portions (121) includes a first sliding plate (1211), a first frame (1212), a first fixing pin (1213), and a pressure module (1214).

[0045] The first sliding plate (1211) is installed to be movable in the forward and backward directions on each rail (111).

[0046] The first frame (1212) is fixed to the first sliding plate (1211).

[0047] The first fixing pin (1213) and the pressure module (1214) are installed in the first frame (1212).

[0048] The first fixing pin (1213) is installed at one end of the first frame (1212).

[0049] Here, one end of the first frame (1212) refers to the end of the first frame (1212) that is in the direction of the center frame (112).

[0050] The first fixing pin (1213) is installed at one end of the first frame (1212) to form a first slit (S1) between the first frame (1212) and the first fixing pin (1213).

[0051] A flat surface (12) can be inserted into the first slit (S1).

[0052] The first pressure module (1214) may include a pressure plate (1214a) and a first transfer unit (1214b).

[0053] The first transfer unit (1214b) is installed on the first frame (1212), and the pressure plate (1214a) is fixed to the first transfer unit (1214b).

[0054] The first transfer unit (1214b) can move the pressure plate (1214a) in the forward and backward directions.

[0055] When the plane (12) is inserted into the first slit (S1), the first transfer unit (1214b) can transfer the pressure plate (1214a) in the direction of the first slit (S1).

[0056] When the first transfer unit (1214b) transfers the pressure plate (1214a) in the direction of the first slit (S1), the pressure plate (1214a) presses the curved surface (11), and at this time, the flat surface (12) can be fixed while inserted into the first slit (S1).

[0057] After the unfixed outer ring (20) is positioned at the edge of the coil (1), when the first sliding plate (1211) moves from each rail (111) toward the center frame (112), the plane (12) is disengaged from the first slit (S1).

[0058] At this time, when the first transfer unit (1214b) transfers the pressure plate (1214a) in the direction of the first slit (S1), the pressure plate (1214a) presses the curved surface (11), so that the inner surface of the curved surface (11) can come into contact with the outer circumference (b) of the side surface (a) of the edge portion of the coil (1).

[0059] The plurality of roller grip portions (122) may include a first roller grip portion (122a) and a second roller grip portion (122b).

[0060] The roller grip portion (122) can overlap both ends of the unfixed outer ring (20) so that after the unfixed outer ring (20) is transferred to the edge portion of the coil (1), the diameter of the curved surface (11) corresponds to the diameter of the coil (1).

[0061] That is, the roller grip portion (122) is unfixed so that after the unfixed outer ring (20) is transferred to the edge portion of the coil (1), the diameter of the curved surface (11) corresponds to the diameter of the coil (1). The ends of the outer ring (20) can be pushed out so that the ends of the outer ring (20) approach each other and overlap.

[0062] To this end, the first roller grip portion (122a) and the second roller grip portion (122b) are arranged adjacent to each other.

[0063] The first roller grip portion (122a) and the second roller grip portion (122b) each include a second sliding plate (1221), a second frame (1222), a second fixing pin (1223), and a roller module (1224).

[0064] The second sliding plate (1221) is installed to be movable in the forward and backward directions on each rail (111).

[0065] The second frame (1222) is fixed to the second sliding plate (1221), and the second fixing pin (1223) and the pressure module (1214) are installed on the second frame (1222).

[0066] The second fixing pin (1223) is installed at one end of the second frame (1222).

[0067] Specifically, the second fixing pin (1223) is installed at the end of the second frame (1222) in the direction of the center frame (112), forming a second slit (S2) between the second frame (1222) and the pin.

[0068] A flat surface (12) can be inserted into the second slit (S2) above.

[0069] The roller module (1224) may include pressure rollers (R1, R2) and a second transfer unit (1224b).

[0070] The second transfer unit (1224b) is installed on the second frame (1222), and the pressure rollers (R1, R2) are fixed to the second transfer unit (1224b).

[0071] The second transfer unit (1224b) can move the pressure rollers (R1, R2) in the forward and backward directions.

[0072] When a flat surface (12) is inserted into the second slit (S2), the second transfer unit (1224b) can transfer the pressure rollers (R1, R2) in the direction of the second slit (S2).

[0073] When the second transfer unit (1224b) transfers the pressure rollers (R1, R2) in the direction of the second slit (S2), the pressure rollers (R1, R2) press the curved surface (11), and at this time, the flat surface (12) can be fixed while inserted into the second slit (S2).

[0074] During the process of installing the unfixed outer ring (20) on the coil (1), when the second sliding plate (1221) moves from each rail (111) toward the center frame (112), the plane (12) is disengaged from the second slit (S2).

[0075] At this time, when the second transfer unit (1224b) transfers the pressure rollers (R1, R2) toward the center frame (112), the pressure rollers (R1, R2) press the curved surface (11) toward the side surface (a) of the coil (1), and the inner surface of the curved surface (11) may come into contact with the outer circumference of the side surface (a) of the edge portion of the coil (1).

[0076] And the first pressure roller (R1) of the first roller grip portion (122a) and the second pressure roller (R2) of the second roller grip portion (122b) each rotate in opposite directions while pressing the curved surface (11), thereby reducing the diameter of the unfixed outer ring (20) so that the diameter of the unfixed outer ring (20) corresponds to the diameter of the coil (1) (see FIG. 7).

[0077] The first pressure roller (R1) of the first roller grip portion (122a) and the second pressure roller (R2) of the second roller grip portion (122b) are each made of an elastic body.

[0078] In addition, on the outer surface of the first pressure roller (R1) of the first roller grip portion (122a) and the second pressure roller (R2) of the second roller grip portion (122b), inclined lines (L1, L2) in the form of protrusions or grooves may be formed in a direction inclined to the axis of rotation.

[0079] The inclined line (L1) of the first pressure roller (R1) and the inclined line (L2) of the second pressure roller (R2) are symmetrical to each other, and the inclined line (L1) of the first pressure roller (R1) and the inclined line (L2) of the second pressure roller (R2) can rotate to bring the flat surface (12) of the outer ring (10) into close contact with the bottom surface (b) of the coil (1).

[0080] Meanwhile, when the diameter of the unfixed outer ring (20) decreases, the inner surface of the curved surface (11) comes into close contact with the outer surface (b) of the side surface (a) of the edge portion of the coil (1), and at this time, if both ends of the unfixed outer ring (20) are fixed to each other, the outer ring (10) can be installed on the edge of the coil (1).

[0082] FIG. 8 is a drawing for explaining the contact sensor part of the outer ring fixing device of FIG. 3, and FIG. 9 is a partial block diagram of the outer ring fixing device of FIG. 3.

[0084] The above contact sensor unit (130) may include a contact detection sensor (131) and a connecting frame (132).

[0085] The above connecting frame (132) is fixed to the frame part (110), and the contact detection sensor (131) is installed on the connecting frame (132).

[0086] When an external force is applied to the contact detection sensor (131), the contact detection sensor (131) can generate a stop signal.

[0087] Specifically, when the outer ring fixing device (100) moves to the bottom surface (b) of the coil (1) by the robot and approaches, and the contact detection sensor (131) is pressed by the bottom surface (b) of the coil (1), the contact detection sensor (131) can generate a stop signal.

[0088] The above contact detection sensor (131) can prevent impact between the unfixed outer ring (20) and the edge of the coil (1) when the outer ring fixing device (100) moves the unfixed outer ring (20) to the edge of the coil (1) by the robot, thereby preventing damage to the unfixed outer ring (20) and the edge of the coil (1).

[0089] The above outer ring fixing device (100) may further include a control unit (140).

[0090] The control unit (140) is connected to the pressure grip unit (121), the plurality of roller grip units (122), and the contact sensor unit (130) to control the operation of the pressure grip unit (121) and the plurality of roller grip units (122), and to receive a stop signal from the contact sensor unit (130).

[0091] When the control unit (140) receives a stop signal from the contact sensor unit (130), the control unit (140) can stop the operation of the robot so that the operation of the robot stops.
