Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of transformer manufacturing, in particular to a coaxial double-skeleton transformer winding device. BACKGROUND

[0002] In the process of manufacturing transformers, the coaxial double-skeleton transformer is mainly prepared by preparing two coaxially matched upper and lower transformer skeletons, enameled copper wire, yellow transparent insulating tape, magnetic core and corresponding pins. After that, the lower skeleton is fixed on the winding machine shaft by manual or simple fixture, a group of windings is wound according to the design parameters, the copper wire tension is manually controlled to ensure close arrangement, the insulating tape is manually pasted after each layer is wound, and the lead-out wires at both ends of the winding are welded to the lower pins. Then, the upper skeleton is positioned and spliced by hand and temporarily fixed, another group of windings is wound, the number of turns and the wire density are manually controlled, the interlayer insulating tape is pasted, and the lead-out wires are welded to the upper pins. Finally, the whole insulating tape is manually wound to form an insulating layer, the pins are arranged and the welded parts are reinforced, the magnetic core is installed to close the magnetic circuit, and the transformer is completed.

[0003] The existing process relies on a large number of manual operations, and has obvious shortcomings. The coaxial splicing and positioning of the double skeleton rely on manual observation and adjustment, and the coaxiality is difficult to guarantee, which may lead to winding deviation and affect the performance of the transformer magnetic circuit and the stability of the electrical parameters. The winding width needs to be measured manually and the fixture needs to be adjusted manually, which is tedious and low in precision, resulting in poor product consistency and inability to quickly adapt to multiple specifications. During winding, the pins lack a special fixing and shaping mechanism and are only temporarily fixed by welding points, which may be loose, deformed or deviated due to winding tension and equipment rotation, affecting the subsequent assembly efficiency and possibly causing poor contact between the winding and the pins, thereby reducing the electrical performance of the product. The interlayer insulating tape pasting and winding tension control rely on manual experience, which may cause uneven tape and loose wire arrangement, increasing the risk of product short circuit. Therefore, it is necessary to design a coaxial double-skeleton transformer winding device to solve the above problems. SUMMARY

When adjusting the winding width, first, the first driving motor 502 of the moving unit 5 is started, the rotating shaft drives the threaded lead screw 503 to rotate, since the moving frame 504 is threadedly connected with the threaded lead screw 503 and slides along the fixed rods 505 on the fixed frame 501, the rotating motion of the threaded lead screw 503 is converted into the linear motion of the moving frame 504, which in turn drives the clamping unit 6 on the upper part to move left and right synchronously, adjusting the relative position of the clamping unit 6 and the sliding block 4, then the second driving motor 603 of the clamping unit 6 is started, the rotating shaft drives the rotating frame 604 to rotate, the clamping frames 605 on the front and rear ends of the mounting frame 601 are gathered around the center of rotation of the rotating frame 604 through the two side connecting rods 606, so that the clamping head 607 is clamped into the clamping groove 401 at the bottom of the sliding block 4, at this time the moving unit 5 continues to drive the clamping unit 6 to move, the sliding block 4 slides outside the sleeve 3 through the clamping head 607, until the preset winding width is reached, then the second driving motor 603 is started in reverse, the clamping frames 605 are opened, and the clamping head 607 is separated from the clamping groove 401, completing the winding width positioning. During the pin shaping and fixing stage, the third drive motor 1003 of the drive unit 10 is started. Its rotating shaft drives the connecting shaft 1004 and the upper drive rod 1005 to rotate. The sliding rod 1008 at the rear end of the drive rod 1005 slides in the guide groove 1007 of the guide frame 1006 to ensure that the drive rod 1005 moves smoothly along the preset trajectory. The drive rod 1005 acts on the pulling member 904 of the pin shaping unit 9, causing it to rotate downward around the second fixed axis 902. Then, through the rotation connection, it drives the pressing member 903 to rotate downward around the first fixed axis 901. Finally, the lower end of the pressing member 903 presses the transformer skeleton pin to prevent the pin from loosening, shifting or deforming during winding, and ensures the relative position accuracy between the winding and the pin.

Through interference fit, the fixed pressure plate 2, sleeve 3, baffle 7 and connector 8 rotate as a whole. The transformer skeleton sleeved on the sleeve 3 rotates synchronously with the sleeve 3. With the cooperation of the external wire feeding mechanism, the wire is wound on the skeleton along the preset trajectory. The slider 4, fixed pressure plate 2 and baffle 7 form a clear winding boundary to ensure that the wire is wound evenly within the limited width. At the same time, the pin shaping unit 9 continuously presses the pin. The connection of each component is stable, and the coaxial double skeleton transformer winding operation is completed. After the operation is completed, the third drive motor 1003 is started in reverse to reset the drive rod 1005. The lower pressure piece 903 is lifted to release the pin. The locking bolt 12 is loosened to separate the rotating shaft 1 from the winding machine shaft 11, and the wound transformer product can be removed.
