DETAILED DESCRIPTION

[0027] The technical solution proposed in this application will be described clearly and completely below in conjunction with the above-mentioned drawings. For those skilled in the art, the described embodiments are only part of the solution of this application rather than all embodiments. Based on the following embodiments, all other embodiments obtained by those skilled in the art without making creative work should belong to the protection scope of this application.

[0028] Embodiment 1, as Figures 1 to 5As shown, the present application proposes a novel three-dimensional winding device for amorphous strips for automated continuous production of core transformers, the device having a double-station unwinding device, which comprises a frame structure 1, two unwinding devices 3 and a rewinding device 8 are respectively arranged at both ends of the same side of the frame structure 1, and a roller device 4, a floating tension adjustment component 5 and a deviation correction device 7 are sequentially arranged between the unwinding device 3 and the rewinding device 8;

[0029] Among them, the unwinding device 3 is used for material output of the amorphous strip 6; the roller device 4 is used for redirecting the amorphous strip 6 when it is wound; the floating tension adjustment component 5 is used to control the adjustment of the surface tension of the amorphous strip 6 during the winding operation; the deviation correction device 7 is used for deviation correction and correction of the amorphous strip 6 along the winding axis; the winding device 8 is used for iron core winding.

[0030] An array of roller devices 4 is provided between the unwinding device 3 and the floating tension adjusting assembly 5. The amorphous strip 6 extends from the unwinding device 3 through the roller device 4 and then changes direction to be wound through the floating tension adjusting assembly 5.

[0031] A plurality of roller devices 4 are arranged between the floating tension adjustment assembly 5 and the deviation correction device 7. The amorphous strip 6 extends from the floating tension adjustment assembly 5 through the roller device 4 and then changes direction and winds through the deviation correction device 7.

[0032] A plurality of roller devices 4 are arranged between the deflection correcting device 7 and the winding device 8 . The amorphous strip 6 extends from the deflection correcting device 7 , passes through the roller devices 4 , and is finally redirected and wound around the winding device 8 .

[0033] The working principle of the three-dimensional winding device for amorphous strip using the above-mentioned double-station unwinding is: the amorphous strip 6 passes from the unwinding device 3 through the roller device 4 and then passes through the floating tension adjustment component 5, and then passes through the floating tension adjustment component 5 and then passes through the roller device 4 and then passes through the deviation correction device 7, and finally passes through the roller device 4 and completes the winding operation at the winding device 8.

[0034] The two unwinding devices 3 are axially fixedly connected to the turret mechanism 2, and the turret mechanism 2 is rotatably connected to the frame structure 1 through a driving device; under the transmission of the driving device, the turret mechanism 2 rotates around its central axis and carries the two unwinding devices 3 to reciprocate on one side of the frame structure 1 to switch and position at the unwinding station.

[0035] The turret mechanism 2 has a rotating plate 16 on which two unwinding devices 3 are installed and fixed. The rotating plate 16 is rotatably connected to the frame structure 1 through a rotating bearing 15. A large gear is sleeved on the outer periphery of the rotating bearing 15. The driving end of the driving motor 18 is connected to the frame structure 1 through the driving end, and a driving gear 17 meshingly connected to the large gear is sleeved on the driving end of the driving motor 18. Driven by the driving motor 18, the driving gear 17 pushes the large gear to rotate while driving the rotating plate 16 to rotate, thereby carrying and driving the two unwinding devices 3 to rotate 180° in the forward or reverse direction around the central axis of the rotating plate 16, thereby realizing the switching of the two unwinding devices 3 at the unwinding station, that is, the unwinding operation of the amorphous strip 6 is carried out on the two unwinding devices 3 in sequence.

[0036] In order to improve the accuracy of the switching operation of the two unwinding devices 3 at the unwinding station, a detection switch 20 is provided on the back of the frame structure 1, and a sensor is installed on one side of the rotating plate 16. The detection switch 20 detects the position signal fed back by the sensor during the rotation process in real time to confirm whether the rotating plate 16 rotates 180° in the forward or reverse direction. When it rotates into place, the drive motor 18 stops working.

[0037] The unwinding device 3 includes an unwinding base 19, on which are arranged a deflection correction electric cylinder 9, a servo motor 10, and two sets of horizontal and parallel linear guide rails 13. The unwinding drum 12 for winding and unwinding the amorphous strip 6 is axially sleeved and fixed to the support 19-1 through the unwinding shaft assembly 11, and the auxiliary roller 14 is parallel to the axial center of the unwinding drum 12 and is axially fixedly connected to the support 19-1. The bottom of the support 19-1 is slidably connected to the linear guide rail 13 through a slider. The servo motor 10 is arranged on the support 19-1, and the servo motor 10 is arranged on the support 19-1. The motor 10 is connected to the unwinding shaft assembly 11 through a synchronous belt and a pulley assembly, and the driving end of the correcting electric cylinder 9 is connected to the support 19-1; driven by the servo motor 10, the unwinding shaft assembly 11 rotates while driving the unwinding drum 12 to rotate for unwinding; driven by the correcting electric cylinder 9, the support 19-1 moves back and forth along the linear guide rail 13 to dynamically adjust the axial distance between the auxiliary roller 14 and the unwinding drum 12 relative to the frame structure 1, thereby ensuring that the cutting reference of the amorphous strip 6 extracted from the unwinding drum 12 is consistent.

[0038] The floating tension adjustment assembly 5 comprises a floating roller 22 for winding and redirecting the amorphous strip 6, the bottom of the floating roller 22 is slidably connected to two sets of slide rails 21 arranged in the horizontal direction, one side of the floating roller 22 is horizontally fixedly connected to the driving end of the cylinder 23, and a group of sensors 24 and a proportional valve 25 for adjusting the cylinder pressure to change its horizontal stroke are installed on one side of the cylinder 23;

[0039] Two sets of slide rails 21 are arranged horizontally on the side of the frame structure 1, so that the interference effect of their own weight on the surface tension control and feedback sensitivity of the amorphous strip 6 can be reduced accordingly; the sensor 24 is used to detect the position of the floating roller 22 in real time and feed back information to the PLC, and the proportional valve 25 adjusts the internal air pressure of the cylinder 23 according to the position of the floating roller 22 fed back by the sensor 24, thereby adjusting the travel distance of the cylinder 23 to push and pull the floating roller 22 in the lateral direction.

[0040] The function of the floating tension adjustment component 5 is to buffer and compensate for the difference between the unwinding speed of the unwinding device 3 and the winding speed of the winding device 8. When the difference between the two is larger, the surface tension of the amorphous strip 6 is larger or smaller, which is not conducive to the winding quality of the amorphous strip 6. In this regard, by adjusting the stroke of the cylinder 23 itself, the displacement of the floating roller 22 sliding along the slide rail 21 is adjusted, which eventually causes the angle of the amorphous strip 6 wound and redirected by the floating roller 22 to change.

[0041] It should be noted that those skilled in the art can also make changes and modifications to the above-mentioned implementations. Therefore, the present application is not limited to the above-mentioned specific implementations, and any obvious improvements, substitutions or modifications made by those skilled in the art on the basis of the present application belong to the protection scope of the present application.

[0042] In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present invention.
