Description
Technical Field
[0001] This utility model relates to the field of electronic device technology, specifically to an amorphous nanocrystalline iron core winding machine. Background Technology
[0002] An amorphous nanocrystalline iron core winding machine is a specialized device for producing amorphous nanocrystalline iron cores. The produced amorphous nanocrystalline iron cores are mainly used in high-frequency transformers or current sensors. This equipment can efficiently and accurately wind amorphous nanocrystalline thin strips into the required iron core shape. In the prior art, patent CN 213649067 U discloses a composite machine that facilitates the adjustment of tape tension. It includes a frame, a first driven winding roller rotatably connected to the upper part of the left front side of the frame, a second driven winding roller rotatably connected to the left front side of the frame and below the first driven winding roller, and an active winding roller rotatably connected to the right front side of the frame. While this equipment can adjust the tape tension using a cylinder, the cylinder's performance is affected by temperature, especially in high or low temperature environments. The cylinder's seals and elastic materials may lose elasticity, affecting the cylinder's stability and making it impossible to accurately match the tape tension changes in real time. Therefore, we propose an amorphous nanocrystalline iron core winding machine. Utility Model Content

[0024] It also includes a control switch group 2, which is located at the right end of the machine body 1. The input end of the control switch group 2 is electrically connected to an external power supply and can regulate the electrical components inside the equipment.
[0025] Among them: the upper and lower sides of the mounting groove 3 are respectively provided with crossbars 10, and the crossbars 10 are slidably connected to the sliding holes provided on the left end of the connecting plate 66. The right end of the connecting plate 66 and the right wall of the mounting groove 3 are respectively provided with springs 11. The springs 11 are all sleeved on the outside of the right side of the crossbars 10. The tension generated by the contraction of the springs 11 can drive the adjusting roller 69 to move and reset through the connecting plate 66.
[0026] Among them, the middle part of the front end of the machine body 1 is respectively provided with guide roller 12, guide roller 23, guide roller 34 and guide roller 45.

Finally, the amorphous nanocrystalline thin strip is fixed to the outside of the mold.
[0027] The mounting slot 3 is rotatably connected to a screw 8 on its rear side. An adjusting plate 61 is threaded to the left side of the outer arc surface of the screw 8 through a threaded hole on its right rear side.

The input end of the motor 9 is electrically connected to the output end of the control switch group 2. The motor 9 starts to run when the control switch group 2 is adjusted. The output shaft of the motor 9 drives the screw 8 to rotate. During the rotation, the screw 8 will drive the adjusting plate 61 to move to the right through the threaded connection.
[0028] Among them: drive motors 16 are respectively installed on the upper and lower sides of the rear end of the machine body 1. The front end of the output shaft of the upper drive motor 16 is fixedly connected to the rear end of the unwinding shaft 4, and the front end of the output shaft of the lower drive motor 16 is fixedly connected to the rear end of the winding shaft 5. The input end of the drive motor 16 is electrically connected to the output end of the control switch group 2. By adjusting the control switch group 2, the drive motor 16 starts to run, and the drive motor 16 drives the unwinding shaft 4 and the winding shaft 5 to rotate. The rotation directions of the unwinding shaft 4 and the winding shaft 5 are opposite. The unwinding shaft 4 releases the amorphous nanocrystalline thin strip through the unwinding plate, and the winding shaft 5 winds the amorphous nanocrystalline thin strip around the outside of the mold to form the required iron core shape.
[0029] The working principle of the amorphous nanocrystalline iron core winding machine provided by this utility model is as follows: Before use, the unwinding reel with the amorphous nanocrystalline thin strip is installed in the middle of the outer arc surface of the unwinding shaft 4. Then, according to the required shape of the amorphous nanocrystalline iron core, the corresponding mold is selected. Finally, the mold is fixed in the middle of the outer arc surface of the winding shaft 5. Then, the amorphous nanocrystalline thin strip is sequentially contacted with the right side of the outer arc surface of the guide roller 2 13, the left side of the outer arc surface of the guide roller 12, the right side of the outer arc surface of the adjusting roller 69, and the guide roller 4. The amorphous nanocrystalline ribbon is then fixed to the outside of the mold by contacting the left side of the outer arc surface of the third roller 14 and the right side of the outer arc surface of the fourth roller 15. Afterwards, the motor 9 starts running by controlling the switch group 2. The output shaft of the motor 9 drives the screw 8 to rotate. During the rotation of the screw 8, the adjusting plate 61 moves to the right through the threaded connection. During the movement of the adjusting plate 61, the bellows 7 on the left extends and the bellows 7 on the right retracts. The bellows 7 on the right has sufficient length. The adjusting plate 61 drives the fixing rod 63 to move to the right through the mounting plate 62. At this time, the fixing rod 63 slides inside the adjusting groove and rotates relative to the adjusting groove, thereby causing the mounting plate 62 to drive the push plate 65 to rotate around the connecting rod 64 through the fixing rod 63. During the rotation of the push plate 65, the push plate 65 will give the connecting plate 66 a rightward push, thereby causing the connecting plate 66 to drive the adjusting roller 69 to move to the right through the fixing seat 67. The spring 11 extends, thereby adjusting the amorphous nanocrystalline ribbon. The tension of the thin strip is adjusted to prevent wrinkling or shifting of the amorphous nanocrystalline thin strip. During the subsequent use of the amorphous nanocrystalline iron core winding machine, the drive motor 16 starts running by controlling the switch group 2. The drive motor 16 drives the unwinding shaft 4 and the winding shaft 5 to rotate. The unwinding shaft 4 and the winding shaft 5 rotate in opposite directions. The unwinding shaft 4 releases the amorphous nanocrystalline thin strip through the unwinding plate, while the winding shaft 5 winds the amorphous nanocrystalline thin strip around the outside of the mold, thereby forming the required iron core shape.
[0030] It is worth noting that the motor 9 disclosed in the above embodiments can be ECMA-C20604RS, the drive motor 16 can be 130ZFMA1-0003CBNM, and the control switch group is provided with control buttons corresponding to the motor 9 and the drive motor 16 for controlling their switches.
