A transformer coil foil winder

Abstract

This invention discloses a transformer coil foil winding machine, relating to the field of transformer coil technology. It includes a base plate, with support frames fixedly connected to the top of the base plate near both left and right sides. A rotating column is provided between two of the support frames near the rear. Grooves are formed on the top of each support frame near the rear. Through the cooperation of a first motor, a second motor, an arc-shaped U-shaped plate, and an L-shaped plate, foil and insulating paper can be passed through two support rollers and wound onto the surfaces of four arc-shaped U-shaped plates between the two L-shaped plates. The first motor drives the rotating column to rotate, which in turn drives the arc-shaped U-shaped plates to rotate. The arc-shaped U-shaped plates then wind the foil and insulating paper. A centrifugal fan adsorbs the foil and insulating paper, causing them to adhere to the lower L-shaped plates, thus preventing misalignment.

Description

Technical Field

[0001] This invention relates to the field of transformer coil technology, specifically to a transformer coil foil winding machine. Background Technology

[0002] A transformer consists of an iron core (or magnetic core) and coils. The coils have two or more windings, of which the winding connected to the power source is called the primary coil, and the remaining windings are called secondary coils. It can transform AC voltage, current and impedance. As a key piece of equipment in the power system, the performance of the transformer directly affects the efficiency and stability of power transmission.

[0003] However, existing foil winding machines have some problems in use. They are not convenient for winding coils of different diameters, which will reduce the winding range of the device. At the same time, during the coil conveying and winding process, the coil may bulge or shift, which will increase the winding difficulty and make it difficult to clean the coil surface.

The foil and insulating paper are then wound around the surfaces of four arc-shaped U-shaped plates. The first motor drives a rotating column to rotate, which in turn drives the arc-shaped U-shaped plates to rotate. The arc-shaped U-shaped plates then wind up the foil and insulating paper. A centrifugal fan adsorbs the foil and insulating paper, ensuring they adhere to the lower L-shaped plates, preventing misalignment and bubbling. Rollers, along with a slider and a second spring, press and limit the movement of the foil and insulating paper. The second motor drives a movable plate to move left and right, with a crossbar limiting its position. The movable plate then drives a brush to move left and right, cleaning the surface of the foil and insulating paper. If the winding is completed, the rotating column needs to be disassembled. First, rotate the bolt to remove it from the inside of the connecting plate and the transmission rod. Then, the connecting rod can be moved upward, which in turn moves the rotating column upward, thus removing the rotating column from the support frame. If the position of the arc-shaped U-shaped plate needs to be adjusted, rotate the double-threaded rod. The double-threaded rod moves the T-block, which in turn moves the arc-shaped U-shaped plate, making it easier to wind the coil into coils of different diameters. Attached Figure Description

[0017] Working principle: When the device starts working, the foil and insulating paper are passed through two support rollers 28 and between two L-shaped plates 20, and then wrapped around the surfaces of four arc-shaped U-shaped plates 6. The first motor 7 and the second motor 30 are started respectively. The first motor 7 drives the transmission rod 8 to rotate. The transmission rod 8 drives the rotating column 3 to rotate through the connecting plate 11 and bolt 12. The rotating column 3 drives the connecting rod 4 to rotate. The connecting rod 4 drives the fixed plate 5 to rotate. The rotating column 3 drives the swing plate 16 to rotate through the T-shaped block 14 and the first U-shaped block 13. The swing plate 16 enters through the second U-shaped block 17. As the circuit rotates, the second U-shaped block 17 drives the arc-shaped U-shaped plate 6 to rotate, which in turn drives the foil and insulating paper to be wound up. Then, the centrifugal fan 21 is activated, which adsorbs the foil and insulating paper, causing them to adhere to the lower L-shaped plate 20, thus preventing the foil and insulating paper from shifting or bubbling. The roller 24, together with the slider 25 and the second spring 26, presses and limits the foil and insulating paper. The second motor 30 is a servo motor, which drives the lower second threaded rod 31 to rotate. 1. The lower grooved wheel 34 drives the belt 35 to rotate, which in turn drives the upper grooved wheel 34 to rotate. The upper grooved wheel 34 drives the upper second threaded rod 31 to rotate, which in turn drives the movable plate 40 to move left and right. The crossbar 32 limits the movable plate 40, and the movable plate 40 drives the brush 41 to move left and right. The brush 41 cleans the surface of the foil and insulating paper. If the winding is completed, the rotating column 3 needs to be disassembled. First, rotate the bolt 12 to remove it from the inside of the connecting plate 11 and the transmission rod 8, then the connecting rod 4 can be moved upward. The connecting rod 4 drives the rotation. The column 3 moves upward, thereby disassembling the rotating column 3 from the support frame 2. If it is necessary to disassemble the L-shaped plate 20, the first threaded rod 23 is removed from the support frame 2 and the limiting plate 22, and the two L-shaped plates 20 can be disassembled. If it is necessary to adjust the position of the arc-shaped U-shaped plate 6, the double threaded rod 15 is rotated, and the double threaded rod 15 drives the T-shaped block 14 to move. The T-shaped block 14 drives the swing plate 16 to swing through the first U-shaped block 13. The swing plate 16 drives the arc-shaped U-shaped plate 6 to move through the second U-shaped block 17, thereby facilitating the winding of coils of different diameter sizes.
