DETAILED DESCRIPTION

[0019] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

The contact head 8 and the conductive contact 7 are electrically disconnected, and the contact head 8 and the conductive contact 7 are electrically connected to the servo motor 6 to form a loop. The servo motor 6 drives the screw 4 to rotate in positive and negative intervals and cooperates with the threaded hole 5 to push the first slider 3 to slide back and forth along the first slide rail 2. When the first slider 3 slides, the contact head 8 contacts the conductive contact 7 to form an energized circuit. The PLC controller is connected to the servo motor 6. When the energized circuit is formed, the servo motor 6 stops briefly and then rotates again, thereby realizing precise control of the transmission through the circuit, solving the problem that the traditional mechanical transmission is prone to position deviation and affects the precise placement of the coil. A clamp 14 replacement mechanism is provided on the front side of the operating table 1, and a wire pressing mechanism is provided above the first slider 3.

[0021] A guide frame 9 is fixedly provided on one side of the first slider 3, and a guide roller 10 is rotatably provided on the upper part of the guide frame 9. When winding, the wire is guided to pass through the guide frame 9, and the guide roller 10 limits the wire to prevent the wire from deviating during winding.

[0022] The fixture 14 replacement mechanism includes a bracket 11, a turntable 12, an installation slide groove 13, a fixture 14 and a limiting sleeve 15. The bracket 11 is symmetrically fixed on the front side of the operating table 1, and a turntable 12 is rotatably provided on the inner side of the bracket 11. The inner side of the turntable 12 is provided with a mounting slide groove 13. A fixture 14 is slidably installed in the mounting slide groove 13. A limiting sleeve 15 is provided on the outer cover of the turntable 12. A wire pressing mechanism is provided on the bracket 11. The turntable 12 and the fixture 14 are tightly fitted with the limiting sleeve 15 on the outside. The turntable 12 is electrically driven by a motor. When the fixture 14 workpiece needs to be replaced, the limiting sleeve 15 is pushed to slide out from the outside of the turntable 12, and then the fixture 14 workpiece is slid out along the mounting slide groove 13 for replacement, so that different fixtures 14 can be quickly and conveniently replaced to adapt to products of different specifications, effectively improving the winding efficiency and reducing the difficulty of operation and maintenance.

[0023] The wire pressing mechanism includes a connecting rod 16, a second slide rail 17, a second slider 18, a spring 19, a wire pressing frame 20 and a wire pressing roller 21. A connecting rod 16 is fixedly provided in the middle of the first slider 3, a second slide rail 17 is transversely fixedly provided above the bracket 11, a second slider 18 is slidably provided below the second slide rail 17, the second slider 18 is fixedly connected to the first slider 3 through the connecting rod 16, a spring 19 is symmetrically fixedly provided on one side below the second slider 18, a wire pressing frame 20 is fixedly provided at the lower end of the spring 19, and a wire pressing roller 21 is rotatably provided in the wire pressing frame 20. When the screw rod 4 rotates to drive the first slider 3 to slide along the first slide rail 2, the second slider 18 is driven by the connecting rod 16 to synchronously slide along the second slide rail 17. After the wire is led out through the guide roller 10, it is guided to the bottom of the wire pressing roller 21 and is pressed on the transformer winding by the spring 19 pressure limit, so that the wire is closely fitted with the transformer winding during winding to ensure the winding effect.

[0024] Before winding, the core material winding machine slides a clamp of corresponding size onto the turntable through an installation slide groove according to the transformer model, and then a limit sleeve is put on the outer periphery of the turntable to fix the clamp. After the transformer is clamped, the wire is passed around the guide roller and the wire pressing roller and then wound around the transformer. The turntable is driven by a motor to rotate and drive the transformer to rotate for winding. At the same time, the servo motor starts to drive the screw to rotate reciprocatingly, and the thread cooperates to drive the first slider to slide reciprocatingly along the first slide rail. The guide roller guides the wire to move synchronously when the first slider slides. When the first slider slides, the contact head contacts the conductive contact in turn and energizes to form a circuit loop. The servo motor stops rotating in turn according to the electrical signal generated by the contact head contacting the conductive contact and energizing, so that the first slider drives the wire to move at regular and precise intervals for winding. When winding, the second slider and the wire pressing frame slide synchronously with the first slider driven by the connecting rod. At the same time, the wire pressing roller fits the transformer under the elastic pressure of the spring and guides the wire to wind tightly.
