[0002] An electronic transformer is a static power device that combines power electronics conversion technology with high-frequency power conversion technology based on the principle of electromagnetic induction to realize the conversion of electrical energy with one power characteristic into electrical energy with another power characteristic, and is mainly used in mobile phones, new energy energy storage, photovoltaic inverters, and new energy vehicles.

[0003] An electronic transformer mainly consists of a high-frequency transformer core (iron core) and two or more coils. They do not change their positions relative to each other.

Specific embodiments

[0023] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As Figures 1 to 3 shown, a feeding and tightening device for a coil winding machine according to an embodiment of the present utility model includes a winding machine body 1; a first motor 2 is fixedly connected to the side wall of the winding machine body 1; the output end of the first motor 2 penetrates the side wall of the winding machine body 1 and is fixedly connected to a winding roller 3; a first transmission roller 4 is rotatably connected to the side wall of the winding machine body 1; a second transmission roller 5 is rotatably connected to the side wall of the winding machine body 1; a second motor 6 is fixedly connected to the side wall of the winding machine body 1; the output end of the second motor 6 penetrates the side wall of the winding machine body 1 and is fixedly connected to a rotating rod 7; a connecting plate 8 is fixedly connected to the end of the rotating rod 7; a pressure wheel 9 is rotatably connected to the side wall of the connecting plate 8. During operation, the copper wire to be wound passes through the second transmission roller 5 and the first transmission roller 4 in sequence and is finally connected to the coil sleeved on the winding roller 3. By turning on the control switch of the winding machine body 1, the first motor 2 drives the winding roller 3 to rotate, so that the copper wire winds on the coil. At this time, the copper wire continuously performs the feeding operation driven by the winding roller 3. When the copper wire is loose during the feeding process and the tension is insufficient, by turning on the switch of the second motor 6, the second motor 6 drives the rotating rod 7 to rotate, so that the pressure wheel 9 located on the connecting plate 8 moves towards the direction close to the copper wire, and the connecting plate 8 presses the copper wire. Then, through the cooperation of the winding roller 3 and the first transmission roller 4, the copper wire is tightened, and the tension during the feeding of the copper wire is adjusted, so that the coil winding and feeding are more stable and safe, and the production quality of the coil is improved.

[0025] AsFigures 1 to 4 As shown, a pair of fixed rods 10 are fixedly connected to the side wall of the winding machine body 1; the end of the fixed rod 10 is fixedly connected with a sleeve 11; the sleeve 11 is arranged between the first driving roller 4 and the second driving roller 5; the inner side walls at both ends of the sleeve 11 are fixedly connected with multiple groups of cleaning brushes 12; the cleaning brushes 12 are arranged in a circumferential array on the sleeve 11. During operation, when the copper wire is fed through the inside of the sleeve 11 during the copper wire feeding process, and when the copper wire is wound and fed, during the process of continuously moving towards the coil on the winding roller 3 driven by the winding roller 3, the cleaning brushes 12 located inside the sleeve 11 clean the surface of the copper wire, reducing the residual production impurities on the copper wire. When the copper wire is wound around the coil, the corrosion of the coil by impurities is reduced. By improving the cleanliness of the coil, the service life of the coil is increased.

[0026] As Figure 2 and Figure 4 As shown, a blower 13 is fixedly connected to the side wall of the winding machine body 1; the output end of the blower 13 is fixedly connected with an air duct 14; the end of the air duct 14 extends into the inside of the sleeve 11 and is fixedly connected to the sleeve 11. During operation, by arranging the blower 13 on the winding machine body 1, when the coil is fed, by turning on the switch of the blower 13, the blower 13 conveys air into the inside of the air duct 14, and sprays it towards the surface of the copper wire through the air duct 14. During the process of feeding the copper wire, when passing through the inside of the sleeve 11, the air flow on the surface of the copper wire is accelerated through the air duct 14, thereby drying the copper wire, reducing the moisture on the surface of the copper wire during the winding and feeding process of the copper wire, making the production of the coil more stable, and improving the production quality of the coil.

[0027] As Figure 3 As shown, a limiting groove 15 is formed in the pressing wheel 9; the limiting groove 15 is arranged in the middle of the pressing wheel 9. During operation, by providing the limiting groove 15 on the pressing wheel 9, when the copper wire is fed and the pressing wheel 9 is used to press the copper wire tightly, the copper wire can be fixed inside the limiting groove 15, reducing the problem of the copper wire falling off during the feeding process and causing failures, and improving the stability during the coil winding and feeding process.

[0028] As Figure 4 As shown, a connecting rope 16 is fixedly connected between the cleaning brushes 12; the connecting rope 16 is arranged in the middle of multiple mutually adjacent cleaning brushes 12. During operation, by providing the connecting rope 16 on the cleaning brushes 12, the cleaning brushes 12 can be made more concentrated, and the cleaning effect on the copper wire is better when cleaning the copper wire, improving the cleaning effect of the cleaning brushes 12 on the copper wire.

[0029] As Figure 1 and Figure 5As shown in the figure, a limiting ring 17 is provided in the middle of the winding roller 3; the limiting ring 17 is sleeved on the winding roller 3 and is in sliding fit with the winding roller 3; an anti-slip pad 18 is fixedly connected to the inner side wall of the limiting ring 17; the anti-slip pad 18 is in contact with the surface of the winding roller 3. During operation, by sleeving the limiting ring 17 on the winding roller 3, when the coil is placed on the winding roller 3 for winding, by sleeving the limiting ring 17 on the winding roller 3, the limiting ring 17 fixes the coil, reducing the possibility of the coil sliding and causing deviation in the winding position of the copper wire, improving the stability during coil winding. The anti-slip pad 18 increases the friction between the limiting ring 17 and the winding roller 3, making the limiting ring 17 more stable on the winding roller 3.

[0030] Working principle: The copper wire to be wound passes through the second driving roller 5 and the first driving roller 4 in sequence and is finally connected to the coil sleeved on the winding roller 3. By turning on the control switch of the winding machine body 1, the first motor 2 drives the winding roller 3 to rotate, and the copper wire winds on the coil. At this time, the copper wire continuously performs the feeding operation driven by the winding roller 3. When the copper wire becomes loose during the feeding process and the tension is insufficient, by turning on the switch of the second motor 6, the second motor 6 drives the rotating rod 7 to rotate, and then the pressing wheel 9 located on the connecting plate 8 moves towards the copper wire, enabling the connecting plate 8 to press the copper wire. Then, through the cooperation of the winding roller 3 and the first driving roller 4, the copper wire is tightened, thereby adjusting the tension during copper wire feeding, making the coil winding and feeding more stable and safe, and improving the production quality of the coil.

[0031] By making the copper wire pass through the inside of the sleeve 11 during the feeding process, when the copper wire winds and feeds, during the process of continuously moving towards the coil on the winding roller 3 driven by the winding roller 3, the cleaning brush 12 located inside the sleeve 11 cleans the surface of the copper wire, reducing the residual production impurities on the copper wire. When the copper wire winds on the coil, it reduces the corrosion of the coil by impurities, and by improving the cleanliness of the coil, the service life of the coil is increased.

[0032] By providing a blower 13 on the winding machine body 1, when the coil is fed, by turning on the switch of the blower 13, the blower 13 conveys air into the air duct 14 and sprays it towards the surface of the copper wire. During the feeding process of the copper wire, when passing through the inside of the sleeve 11, the air flow on the surface of the copper wire is accelerated through the air duct 14, thereby drying the copper wire, reducing the moisture on the surface of the copper wire during the winding and feeding process of the copper wire, making the production of the coil more stable, and improving the production quality of the coil.

[0033] By providing a limiting groove 15 on the pressing wheel 9, when the copper wire is being fed and the pressing wheel 9 is used to tightly press the copper wire, the copper wire can be fixed inside the limiting groove 15, reducing the problem of the copper wire falling off during the feeding process and causing failures, and improving the stability during the coil winding feeding process.

[0034] By providing a connecting rope 16 on the cleaning brush 12, the cleaning brush 12 can be made more concentrated, and the cleaning effect on the copper wire is better when cleaning the copper wire, improving the cleaning effect of the cleaning brush 12 on the copper wire.

[0035] By sleeving a limiting ring 17 on the winding roller 3, when the coil is placed on the winding roller 3 for winding, by sleeving the limiting ring 17 on the winding roller 3, the limiting ring 17 fixes the coil, reducing the possibility of the coil sliding and causing deviation in the winding position of the copper wire, improving the stability during coil winding. By means of the anti-slip pad 18, the friction between the limiting ring 17 and the winding roller 3 is increased, making the limiting ring 17 more stable on the winding roller 3.
