[0053] The specific working principle and technical details of the automatic winding device for the inductor are as follows.

[0054] According to the type (rectangular or annular) and size of the wound coil, a winding mold 6 is selected and fixed to the clamping seat 13. The first motor 8 drives the lead screw 9 to rotate, and the rotary motion is converted into the horizontal motion of the first vertical plate 12 along the first slide rail assembly Y through the lead screw nut. The second motor 11 drives the clamping seat 13 to move along the second slide rail assembly in the Z direction through the first synchronous belt 16, so as to move the winding mold 6 to the winding position of the winding mechanism 4.

[0055] Under the clamping of the external wire feeding device (not shown in the figure), the enameled wire passes through the hollow conduit 56 to the upper side of the target winding roller 39. The first jaw air cylinder 25 is started to clamp the enameled wire, and then the third motor 21 is started to drive the first rotating shaft 28 to rotate 180 degrees clockwise (facing the winding mold 6), so as to turn the first jaw air cylinder 25 from the initial position to the position directly below the winding roller 39. Then, the first air cylinder 23 pulls the first jaw air cylinder 25 to move backward along the X axis, and the enameled wire is automatically embedded in one of the wire clamping grooves 41 (the opening of the wire clamping groove 41 is provided with a guide notch to facilitate the introduction of the enameled wire) under the action of the traction force, so as to complete the fixation of the enameled wire and the winding roller 39.

[0056] Subsequently, the fourth motor 38 rotates at low speed to drive the hollow rotating shaft 31 to rotate through the transmission system, and the hollow rotating shaft 31 transmits the torsion to the jackscrew 32 to rotate at low speed synchronously, at the same time, the second cylinder 48 pulls the push plate 30 to make the jackscrew 32 gradually close to the winding roller 39, and the insertion column 44 and the insertion slot 42 are automatically centered through the taper surface cooperation. Then, the fourth motor 38 rotates at high speed to wind the coil. When the fourth motor 38 rotates at high speed, the fifth motor 50 starts to drive the hollow conduit 56 on the first supporting plate 66 to feed along the X axis at a speed linked with the rotating speed of the winding roller 39, so as to ensure that the enameled wire is uniformly wound on the winding roller 39 and avoid the stacking defects.

[0057] When the winding roller 39 winds a certain number of turns, the third cylinder 71 pushes out the second jaw cylinder 54, and the two cutters 55 move towards each other to cut the enameled wire, thus completing the winding work of one winding roller 39. After winding each winding roller 39, the feeding mechanism 1 drives the winding mold 6 to advance a certain distance to perform the winding process of the next winding roller 39, until all the winding rollers 39 are wound.

[0058] When all the winding rollers 39 are wound, the feeding mechanism 1 drives the winding mold 6 to return to the starting position to provide a reference coordinate for the discharging process. The eighth motor 79 drives the second supporting plate 84 to feed along the X axis through the seventh synchronous belt 78, and as the distance of the second supporting plate 84 is close, the winding roller 39 is embedded in the placement cavity (the cavity between the top block 99 and the corresponding clamping groove 100). Then, the fourth cylinder 95 and the fifth cylinder 97 pull the pressing rod 98 at the same time, and the coil on the winding roller 39 is clamped between the top block 99 and the corresponding clamping groove 100. Then, the eighth motor 79 drives the second supporting plate 84 to retreat through the seventh synchronous belt 78, so that the coil is separated from the winding roller 39. Immediately, the ninth motor 80 drives the material taking assembly 83 to rotate 90 degrees, at this time, the material taking assembly 83 is opposite to the discharging hole 77. Finally, the fourth cylinder 95 and the fifth cylinder 97 push the pressing rod 98 at the same time, and the coil is separated from the placement cavity under the action of gravity and falls into the receiving box (not shown in the figure) below the discharging hole 77.
