DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1: Figure 1-Figure 4As shown, the technical solution adopted in this embodiment is as follows: a mutual inductor winding mechanism, comprising: a base plate 1, on which support members that can be close to each other are symmetrically arranged, a second motor 6 is fixedly arranged on the upper part of the support member, a turntable 7 is fixedly arranged on the output end of the second motor 6, a right-angle plate 8 is rotatably arranged on the circumference of the turntable 7 through a fixed shaft 9, a first torsion spring is sleeved on the outside of the fixed shaft 9, one end of the first torsion spring is fixedly connected to the turntable 7, and the other end of the first torsion spring is fixedly connected to the right-angle plate 8; the end of the right-angle plate 8 away from the second motor 6 approaches each other under the action of the first torsion spring, and the end of the right-angle plate 8 that is close to each other is hinged with a top block 11 through a hinge shaft 10, a second torsion spring is sleeved on the outer circumference of the hinge shaft 10, one end of the second torsion spring is fixedly connected to the right-angle plate 8, and the other end of the second torsion spring is fixedly connected to the top plate, and the top plate is parallel to the horizontal section of the right-angle plate 8 under the action of the second torsion spring. The right-angle plates 8 on the two turntables 7 are driven to approach each other by the support members, so that the two groups of right-angle plates 8 extend from the two ends of the iron core into the inside of the iron core. As the support members continue to move, the vertical sections of the two groups of right-angle plates 8 contact the two ends of the iron core and push the right-angle plates 8 to rotate along the fixed axis 9. As the right-angle plates 8 rotate, the first torsion spring is squeezed and deformed, playing a buffering role to prevent the right-angle plates 8 from moving quickly and causing the iron core to bump. As the support members move, the right-angle plates 8 rotate so that the top blocks 11 on the right-angle plates 8 contact the inner wall of the iron core from the inside of the iron core. At this time, the top plate gradually squeezes the second torsion spring by tilting, so that it rotates to be parallel to the iron core and sticks to the inner wall of the iron core from the inside, completing the fixation of the iron core. At the same time, the iron core is fixed from both sides to prevent the iron core from axial displacement during winding, thereby improving the winding quality.

[0023] A reciprocating screw 12 is rotatably arranged at one end of the bottom plate 1 away from the support, a limit rod 14 is fixedly arranged below the reciprocating screw 12, the limit rod 14 is horizontal with the reciprocating screw 12, a slider 15 is connected to the outer circumference of the reciprocating screw 12 through a crescent pair of the reciprocating screw 12, the slider 15 is slidably connected to the limit rod 14, and a guide hole 16 is fixedly arranged above the slider 15. A third motor 13 is fixedly arranged on the bottom plate 1, and the output end of the third motor 13 is fixedly connected to the reciprocating screw 12. The reciprocating screw 12 is driven to rotate by the third motor 13, so that the reciprocating screw 12 drives the slider 15 to move left and right, so that the slider 15 drives the guide hole 16 to move left and right, so that the wire is evenly wound on the outer circumference of the iron core.

[0024] The support member includes a first motor 4, a double-threaded lead screw 3 and a support frame 5. A first slide groove 2 is provided on the base plate 1, and the double-threaded lead screw 3 is rotatably connected in the first slide groove 2. The first motor 4 is fixedly arranged on one side of the base plate 1, and the output shaft of the first motor 4 is fixedly connected to the double-threaded lead screw 3. There are two support frames 5, and threads with opposite rotation directions are distributed at both ends of the double-threaded lead screw 3, and the two support frames 5 are respectively threadedly connected to the two ends of the double-threaded lead screw 3, and the lower ends of the support frames 5 are slidably arranged in the first slide groove 2. The second motor 6 is fixedly arranged above the support frame 5. The double-threaded lead screw 3 is driven to rotate by the first motor 4, so that the double-threaded lead screw 3 drives the two support frames 5 to move toward each other, so that the right-angle plate 8 fixes the iron core. Then, the second motor 6 rotates, and the iron core can be driven to rotate through the turntable 7 and the right-angle plate 8 for winding.

[0025] Working principle: When in use, first pick up the iron core and place it between the two turntables 7, then start the first motor 4, the first motor 4 drives the double-threaded screw 3 to rotate, so that the double-threaded screw 3 drives the turntable 7 to approach each other through the support frame 5, so that the end of the right angle plate 8 that is close to each other is transmitted into the inside of the iron core, and the two ends of the iron core contact the vertical section of the right angle plate 8, and push the vertical section to make the right angle plate 8 rotate along the fixed axis 9. As the right angle plate 8 rotates, the first torsion spring is squeezed and deformed, which plays a buffering role to prevent the right angle plate 8 from moving quickly and causing the iron core to bump. As the support moves, the right angle plate 8 rotates so that the top block 11 on the right angle plate 8 contacts the inner wall of the iron core from the inside of the iron core. At this time, the top plate gradually squeezes the second torsion spring by tilting, so that it rotates to be parallel to the iron core, and is close to the inner wall of the iron core from the inside, completing the fixation of the iron core. At the same time, the iron core is fixed from both sides to prevent the iron core from axial displacement during winding, thereby improving the winding quality.

[0026] The wire is then passed through the guide hole 16 and wound around the iron core, and then the third motor 13 and the second motor 6 are started. The second motor 6 drives the turntable 7 to rotate, so that the turntable 7 drives the iron core to rotate through the right-angle plate 8 and the top block 11. The third motor 13 drives the guide hole 16 on the slider 15 to move left and right so that the wire is evenly wound around the iron core, further improving the winding quality.

A second slide groove 22 is provided at one end of the base plate 1, and the mobile frame 23 is slidably arranged inside the second slide groove 22, and the telescopic rod 17 is fixedly arranged in the second slide groove 22, and the output end of the telescopic rod 17 is fixedly connected to the mobile frame 23, the fixed frame 18 is arranged on the base plate 1, and the positions of the fixed frame 18 and the mobile frame 23 correspond, and the second motor 6 is fixedly arranged on the upper ends of the mobile frame 23 and the fixed frame 18. A first pulley 19 is fixedly arranged on the outer side of the turntable 7 at one end of the fixed frame 18, and a second pulley 21 is fixedly arranged at one end of the reciprocating screw 12, and a belt 20 is wound between the first pulley 19 and the second pulley 21.

[0028] The mobile frame 23 is driven by the telescopic rod 17 to approach the fixed frame 18 to complete the fixation of the iron core, and the reciprocating screw 12 is driven to rotate by the first pulley 19, the second pulley 21 and the belt 20, so that the turntable 7 drives the iron core and the reciprocating screw 12 to rotate at the same time, saving resources while enabling the reciprocating screw 12 to smoothly drive the guide hole 16 to move left and right.
