Technical Field

[0001] The utility model relates to the technical field of transformer core winding, in particular to a transformer core winding device. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to transmit and transform AC power. It consists of two or more coils wound on a shared magnetic core. The main winding is connected to an AC power source, and the current passing through it generates an alternating magnetic field, thereby inducing an electromotive force in the secondary winding. Transformers are generally used in power systems, mainly for voltage rise and fall, current change, isolation and impedance matching. The winding of the transformer core is an important part of the transformer manufacturing process. The main function of the core is to conduct the magnetic field and reduce energy loss. The winding process of the core includes winding the winding on the core tightly and evenly to ensure the quality of insulation and power transmission.

[0003] When there is dust on the surface of the core, uneven dust deposition may occur during the winding process, which will lead to inconsistent gaps between windings and uneven current distribution, thus affecting the performance and reliability of the transformer.

[0004] In order to solve the above problems, the present application proposes a transformer core winding device. Utility Model Content

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0019] like Figure 1-3 As shown, a transformer core winding device proposed by the utility model comprises a workbench 1;

[0020] In this embodiment, a spindle 2 and a servo motor 3 for driving the spindle 2 to rotate are installed on the workbench 1, and a sleeve block 4 slidably sleeved on the spindle 2 and a driving member for driving the sleeve block 4 to move on the spindle 2 are installed on the workbench 1. The driving member includes an electric push rod 9. A mounting groove is provided in the workbench 1, and the electric push rod 9 is installed in the mounting groove. The sleeve block 4 is connected to the electric push rod 9 and is driven by the electric push rod 9 to approach or move away from the workbench 1.

[0021] In this embodiment, the sleeve block 4 is connected to the vent pipe 5 located on one side of the main shaft 2 through the elastic member 6. The elastic member 6 includes a connecting rod 61, a sleeve shaft 62 and a spring 63. A slide groove is provided in the sleeve block 4, the connecting rod 61 is installed in the slide groove, the sleeve shaft 62 is slidably sleeved on the connecting rod 61 and slidably connected to the slide groove, the spring 63 is sleeved on the connecting rod 61, and the two ends of the spring 63 are respectively connected to the sleeve shaft 62 and the inner wall of the slide groove, and the vent pipe 5 is installed on the sleeve shaft 62.

[0022] In this embodiment, a roller dust blowing member 7 connected to the vent pipe 5 is rotatably sleeved. The roller dust blowing member 7 includes a fixed shaft 71 and a roller 72. There are two fixed shafts 71, both of which are slidably sleeved on the vent pipe 5. The roller 72 is rotatably connected between the two fixed shafts 71 and sleeved on the vent pipe 5. A plurality of vent holes are provided on the periphery of the vent pipe 5. A dust blowing cavity connected to the vent holes is provided in the roller 72. A plurality of dust blowing holes 73 connected to the dust blowing cavity are provided on the periphery of the roller 72. A bolt 74 pressed against the vent pipe 5 is threadedly connected to the fixed shaft 71.

[0023] In this embodiment, a gas supply member 8 for conveying gas to the vent pipe 5 is installed on the workbench 1. The gas supply member 8 includes a joint 81, an air outlet pipe 82, and an air inlet pipe 83. The joint 81 is installed on the outside of the sleeve block 4.

[0025] In order to facilitate dust removal during the winding of the transformer core, the main shaft 2 can be driven to rotate by the servo motor 3, so that the core material is wound on the main shaft 2. When the number of turns of the core material is gradually increased, it can abut against the roller 72 and drive the roller 72 to rotate, and apply an outward force to the roller 72, so that the vent pipe 5 drives the sleeve shaft 62 to slide on the connecting rod 61 and compress the spring 63. When the core is winding, the air inlet pipe 83 can be connected to the air pump, so that the gas passes through the joint 81 and enters the vent pipe 5 along the air outlet pipe 82, and the gas immediately enters the roller 72. The gas can be blown toward the core through the dust blowing hole 73 on the roller 72 to remove dust on the surface of the core. This structure blows the gas toward the core through the roller dust blowing member 7, which can effectively remove dust on the surface of the core, avoids the unevenness caused by dust deposition during the winding process, and improves the performance and reliability of the transformer.

[0026] After the iron core is wound, the sleeve block 4 can be driven to move on the main shaft 2 by the electric push rod 9, so that the wound iron core can be pushed out from the main shaft 2.
