after the two wires L1 are spot-welded and fixed to the first electrode W11 and the second electrode W12, 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 core W start to twist; the first holder B412 and the second holder B422 simultaneously rotate with the core W being held by the axis line of the core W3 as the rotation center, and twist the two wires L1 while winding the two wires L1 around the outer circumference of the core W3 by the rotation of the core W;

after the two wires L1 are uniformly wound around the winding core W3, referring to fig. 15, the two wires L1 are respectively wound around the third electrode W21 and the fourth electrode W22 of the second flange portion W2 and spot-welded and fixed on the third electrode W21 and the fourth electrode W22 by the moving fixture B5 and the plurality of second wire hanging bodies B4221, so as to complete the winding operation;
when the iron core W rotates to wind the two wires L1 around the winding core W3, since the two wires L1 are continuously wound around the winding core W3, the two wires L1 are continuously pulled downward, so that the wires L1 on the two coils L are continuously unwound to form the coil L, and the unwound wires L1 are first moved toward one end of the coil L and pulled out through the opening a1151, then pass through the guide hole a1221, and the wires L1 passing through the guide hole a1221 are moved downward toward the corresponding tension controllers a 21; after passing through the wire feeding frame a22 to the corresponding tension controller a21, the wire L1 unwound from the wire coil L 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 through the wire feeding frame a23 downwards to the winding mechanism B1 of the winding device B; when the wire L1 is pulled downward, the wire L1 between the pulley a212 and the fixed pulley a214 (fig. 5) located at the left side of the movable pulley a213 is pulled, so that the wire L1 pulls the movable pulley a213 to move upward and drive the swing arm a216 to swing upward to store 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 wire driver a215 controls the pulley a212 to rotate counterclockwise to pull the wire L1 into the tension controller a21, and at this time, the wire L1 between the pulley a212 and the fixed pulley a214 located at the left side of the movable pulley a213 is converted from tension to relaxation, so that the swing arm a216 swings downward under the elastic restoring force of the elastic member a218, and when the sensor a217 senses that the swing arm a216 swings to a predetermined angle, the wire driver a215 controls the pulley a212 to stop rotating, thus reciprocally controlling the rotation of the pulley a212 to control the unwinding of the wire L1 from the winding device B;
when the nozzle rotation driving mechanism B11 of the winding mechanism B1 rotates to twist the two wires L1, the second rotation mechanism A4 will drive the tension control mechanism A2 to rotate in cooperation with the rotation direction and rotation speed of the nozzle rotation driving mechanism B11 in order to avoid twisting the two wires L1 from the nozzle rotation member B113 to the tension control mechanism A2; when the tension control mechanism A2 rotates, in order to prevent the tension control mechanism A2 to the two wires L1 of the coil support mechanism A1 from twisting together, the first rotation mechanism A3 will drive the coil support mechanism A1 to rotate in cooperation with the rotation direction and rotation speed of the tension control mechanism A2; the nozzle rotation driving mechanism B11, the tension control mechanism A2 and the coil supporting mechanism A1 can synchronously rotate in the same direction or rotate in the same direction at a preset time 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 the coil supporting mechanism A1 are controlled not to twist together at a preset time interval, for example, after the nozzle rotating member B113 of the nozzle rotation driving mechanism B11 starts to rotate clockwise for 1/4 of a turn, the tension control mechanism A2 starts to rotate clockwise, and after the tension control mechanism A2 rotates 1/4 of a turn, the coil supporting mechanism A1 starts to rotate clockwise.
According to the winding method and the winding equipment, the wire supply device A can supply a plurality of wires L1 to the winding device B, and when the winding device B winds the plurality of wires L1 on the iron core W while twisting, the coil supporting mechanism A1 and the tension control mechanism A2 of the wire supply device A can be driven to rotate so as to prevent the plurality of wires L1 which do not reach the winding device B from being excessively twisted to be knotted, so that twisting and winding of the plurality of wires L1 can be expected; the wire feeding device A and the winding device B are arranged vertically, the rotation axis D2 of the coil supporting mechanism A1 and the rotation axis D3 of the tension control mechanism A2 are approximately perpendicular to the axis D1 of each coil L, so that the coil L can be replaced conveniently, and the occupied area of winding equipment can be reduced.
The foregoing description of the preferred embodiments of the invention should not be taken as limiting the scope of the invention, which is defined by the appended claims and their description, but rather by the description of the invention, as long as they are defined by the claims.
