In the embodiment of the present invention, the wire supplying device a supplies two wires L1 unwound from the two wire coils L to the winding device B, so that the two wires L1 can be wound around the core W after being twisted;

after the iron core W passes through the linear feeding flow path of the vibration feeding track B21 to the waiting position P1, the jacking seat B31 moves upward to move the iron core W located at the waiting position P1 to the operating position P2, and the second retainer B422 approaches the first retainer B412, so that the first retainer B412 and the second retainer B422 respectively contact the first flange portion W1 and the second flange portion W2 of the iron core W to clamp the iron core W;

after the first holder B412 and the second holder B422 clamp the core W, the lifting seat B31 is downwardly displaced to return to the waiting position P1 capable of receiving the core W, so that the first flange portion W1 and the second flange portion W2 of the core W left at the operating position P2 are held and the core portion W3 is suspended to prepare for winding operation;

when preparing to perform the winding operation, please refer to fig. 12 and 13, the nozzle rotating member B113 can move to the side of the iron core W and make the two nozzles B1131 thereon discharge two wires L1, respectively, after acting with the first wire hanging bodies B4121 by a moving clamp B5, the two wires L1 can respectively wind around the first electrode W11 and the second electrode W12 of the first flange portion W1 and fix the two wires L1 to the first electrode W11 and the second electrode W12 by spot welding;

after the two wires L1 are fixed to the first electrode W11 and the second electrode W12 by spot welding, referring to fig. 14, the nozzle rotating member B113 starts to rotate, so that the two wires L1 between the two nozzles B1131 and the iron core W start to be twisted; the first holder B412 and the second holder B422 hold the core W and rotate around the axis of the core W3, so that the two wires L1 are twisted and the two wires L1 are wound around the outer periphery of the core W3 by the rotation of the core W;

while the two wire rods L1 are being wound around the winding core portion W3, the nozzle rotor B113 is movable from one end of the winding core portion W3 near the first flange portion W1 to the other end near the second flange portion W2, so that the two twisted wire rods L1 are uniformly wound around the winding core portion W3 in the longitudinal direction;

after two wires L1 are uniformly wound around the core W3, please refer to fig. 15, after two wires L1 are acted on the second wire suspension bodies B4221 by the movable clamp B5, they are wound around the third electrode W21 and the fourth electrode W22 of the second flange W2, and the two wires L1 are fixed to the third electrode W21 and the fourth electrode W22 by spot welding, so as to complete the winding operation;

when the iron core W rotates to wind the two wire rods L1 around the winding core W3, because the two wire rods L1 are continuously wound around the winding core W3, the two wire rods L1 are continuously pulled downward, the wire rods L1 on the two wire coils L are continuously unwound from the wire coils L, the unwound wire rods L1 move toward one end of the wire coils L to be drawn out from the opening a1151, then pass through the guide hole a1221, and the wire rods L1 passing through the guide hole a1221 move downward toward the corresponding tension controller a 21; a wire L1 unwound from the coil L passes through the wire-feeding frame a22 to the corresponding tension controller a21, then sequentially passes through the cleaning wheel a211, a part of the fixed pulley a214, the belt pulley a212, the movable pulley a213 and the rest of the fixed pulleys a214, and then passes downward through the wire-releasing frame a23 to the wire-winding mechanism B1 of the wire-winding device B; when the wire L1 is pulled downward, the wire L1 between the belt pulley a212 and the fixed pulley a214 (fig. 5) on the left side of the movable pulley a213 is pulled, so that the wire L1 pulls the movable pulley a213 to move upward and drives the swing arm a216 to swing upward to accumulate the elastic restoring force of the elastic member a218, when the sensor a217 senses the swing of the swing arm a216 to a predetermined angle, the tape drive a215 controls the tape reel a212 to rotate counterclockwise to draw the wire L1 into the tension controller a21, at which time, the wire L1 between the belt pulley a212 and the fixed pulley a214 on the left side of the movable pulley a213 is converted from tension to slack, so that the swing arm a216 swings downward under the elastic restoring force of the elastic member a218, when the sensor a217 senses that the swing arm a216 swings to a predetermined angle, the tape driver a215 controls the tape reel a212 to stop rotating, thus reciprocally controlling the rotation of the tape reel a212 to control the tension of the wire L1 unwound from the coil L to the winding device B;

when the nozzle rotation driving mechanism B11 of the winding mechanism B1 is rotating to twist two of the wires L1, in order to avoid twisting together of the two wires L1 from the nozzle rotating member B113 to the tension controlling mechanism a2, the second rotating mechanism a4 will drive the tension controlling mechanism a2 to rotate in accordance with the rotating direction and the rotating speed of the nozzle rotation driving mechanism B11; in order to avoid the two wires L1 of the tension control mechanism a2 to the wire reel support mechanism a1 from twisting together when the tension control mechanism a2 is rotated, the first rotation mechanism A3 will drive the wire reel support mechanism a1 to rotate in accordance with the rotation direction and rotation speed of the tension control mechanism a 2; the nozzle rotation driving mechanism B11, the tension control mechanism a2, and the coil support mechanism a1 may rotate synchronously in the same direction or in the same direction at a predetermined interval, but the two wires L1 between the nozzle rotation driving mechanism B11 and the tension control mechanism a2, between the tension control mechanism a2, and between the coil support mechanism a1 are controlled at a predetermined interval so as not to be twisted together, and if the nozzle rotating member B113 of the nozzle rotation driving mechanism B11 starts to rotate clockwise by 1/4 turns, the tension control mechanism a2 starts to rotate clockwise, and if the tension control mechanism a2 rotates 1/4 turns, the coil support mechanism a1 starts to rotate clockwise.

In the winding method and apparatus according to the embodiments of the present invention, the wire supply device a may supply a plurality of wires L1 to the winding device B, and when the winding device B twists and winds a plurality of wires L1 around the core W, the coil support mechanism a1 and the tension control mechanism a2 of the wire supply device a may be driven to rotate, so as to prevent the wires L1 that have not reached the winding device B from being twisted excessively and knotted, so that the twisting and winding of the wires L1 may meet expectations; the wire supplying device A and the winding device B are arranged up and down, and the rotation axis D2 of the coil supporting mechanism A1 and the rotation axis D3 of the tension control mechanism A2 are approximately vertical to the axis D1 of each coil L, which not only facilitates the replacement of the coil L, but also reduces the area occupied by the winding equipment.

The above description is only a preferred embodiment of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made in the claims and the description of the present invention are within the scope of the present invention.
