Description
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] The transformer core is the main magnetic circuit part of the transformer. It is usually made of hot-rolled or cold-rolled silicon steel sheets with a high silicon content and coated with insulating paint on the surface. The iron core and the coil wound on it form a complete electromagnetic induction system; and the winding device is a device that winds the wire onto a specific iron core, usually used for copper wire winding.
[0003] Traditional winding is to manually gather multiple layers of wires together so that they overlap when viewed from above, and then manually wind the overlapping wires onto the core while controlling the core to rotate. This operation method not only has extremely low winding efficiency but also has defects. Since it is a manual operation, the force of the wires wound around the core is uneven, resulting in different tightness of each layer of wires, affecting the overall quality of the transformer. At the same time, since it is a manual operation, multiple layers of wires are very easy to spread out, and the wires need to be repeatedly gathered together manually. The wires cannot be automatically aligned in the vertical direction, and when the winding of the wires is skewed, it cannot automatically correct the deviation, affecting production efficiency. To address the above problems, we have introduced a transformer core winding device. Utility Model Content

[0023] The utility model discloses a transformer core winding device which is mainly used in transformer winding production scenarios.

[0025] In the above technical scheme, it is taken into account that the force of manual operation of winding the wire around the iron core is uneven, resulting in different tightness of each layer of wire. In order to solve such problems, the specific operations are as follows: pull out one end of the wire through the top of the wire drum 3, pass through the bottom of the guide cylinder 5, pass through the through hole 9 in the moving block 8, and wind it around the iron core body 12. Start the second motor 10 to drive the iron core body 12 to rotate and perform the winding work. At this time, the displacement component will also smoothly drive the moving block 8 to move left and right, so that the wire can be evenly wound around the iron core body 12, and the distance between the windings can be accurately controlled. At the same time, one end of the pressing component will also be placed on the top and one side of the iron core body 12, and it will always be in contact with the iron core body 12, thereby pressing the wire, so that the iron core body 12 is in close contact with the winding coil during the winding process, thereby improving the consistency and uniformity of the winding and reducing the gaps and looseness in the winding.
[0026] Reference Figures 3 to 5 In a preferred embodiment, the pressing assembly includes a fixing rod 15, which is fixedly connected to the inside of the connecting frame 14, and the outer side of the fixing rod 15 is rotatably connected to the support frame 17. The bottom of the support frame 17 is provided with a mounting groove 19, and the inside of the mounting groove 19 is rotatably connected to a rotating rod 20, and both ends of the rotating rod 20 extend to both sides of the support frame 17 and are fixedly connected to a connecting block 21, and a rotating roller 22 is rotatably connected between one side of the connecting block 21, and the outer side of the rotating roller 22 contacts the outer side of the core body 12, and the pressing assembly also includes a connecting plate 13, which is fixedly connected to the bottom of the inner wall of the connecting frame 14, and a first fixing block 24 is fixedly connected to the top of the support frame 17, and a first fixing column 25 is fixedly connected to one side of the first fixing block 24, and a second fixing block 26 is fixedly connected to the top of the connecting plate 13, and a second fixing column 27 is fixedly connected to one side of the second fixing block 26, and a cylinder 18 is rotatably connected between the outer side of the first fixing column 25 and the outer side of the second fixing column 27;
[0027] In the above technical scheme, the problem of different tightness of each layer of wire in the iron core is taken into consideration. In order to solve such problem, the specific operation is as follows: during the winding process, the iron core body 12 can drive the support frame 17 to swing slightly around the fixed rod 15 by utilizing the cylinder 18, so that the two rotating rollers 22 are in contact with the top and side of the iron core body 12, and the two rotating rollers 22 are in contact with the wire. Then, when winding, the wire can be pressed, so that the iron core body 12 is in close contact with the winding coil during the winding process, thereby improving the consistency and uniformity of the winding. By utilizing the rotational relationship between the cylinder 18, the connecting block 21 and the rotating roller 22, the rotating roller 22 can still fit the iron core body 12 during its rotation.
[0028] Reference Figure 3 In a preferred embodiment, a double-hook spring 23 is rotatably connected between one side of the connecting block 21 and one side of the support frame 17; by utilizing the double-hook spring 23, the connecting block 21 can be buffered more smoothly during the swinging process, so that the rotating roller 22 fits more closely with the core body 12.
[0029] Reference Figure 1 and Figure 2 In a preferred embodiment, the displacement assembly includes a third screw rod 7, which is rotatably connected to the inside of the shell 1, and the outer side of the third screw rod 7 is connected to the internal thread of the moving block 8. A first motor 6 is fixedly installed on one side of the shell 1, and one end of the output shaft of the first motor 6 is fixedly connected to one end of the third screw rod 7. A sliding rod 16 is fixedly connected to the inside of the shell 1, and the outer side of the sliding rod 16 is slidably connected to the inside of the moving block 8; the third screw rod 7 is driven to rotate by starting the first motor 6, thereby driving the moving block 8 to move smoothly, so that the wire can be evenly wound around the core body 12, and the distance between the windings can be accurately controlled. By setting the sliding rod 16, the moving block 8 can be limited to prevent the moving block 8 from rotating and affecting the winding work.
[0030] Reference Figure 1 and Figure 2 In a preferred embodiment, a scale is provided at the bottom of the inner wall of the housing 1; by providing the scale, the distance moved by the moving block 8 can be understood, and the frequency of the motor rotation can be better controlled.
[0031] Working principle: When in use, the wire is pulled out from the top of the wire drum 3, passed through the bottom of the guide cylinder 5, passed through the through hole 9 in the moving block 8, and wound around the core body 12. The second motor 10 is started to drive the core body 12 to rotate and perform the winding work. The third screw rod 7 is driven to rotate by starting the first motor 6, thereby driving the moving block 8 to move smoothly, so that the wire can be evenly wound around the core body 12. At the same time, during the winding process, the core body 12 can drive the support frame 17 to swing slightly around the fixed rod 15 by using the cylinder 18, so that the two rotating rollers 22 are in conflict with the top and side of the core body 12, and the two rotating rollers 22 are in conflict with the wire. Then, when winding, the wire can be pressed, so that the core body 12 is in close contact with the winding coil during the winding process, thereby improving the consistency and uniformity of the winding. By utilizing the rotation relationship between the cylinder 18, the connecting block 21 and the rotating roller 22, the rotating roller 22 can still fit the core body 12 during its rotation.

The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
