Description

Technical Field

[0001] This utility model relates to the field of amorphous and nanocrystalline iron core processing technology, specifically an automatic winding machine for amorphous and nanocrystalline iron cores. Background Technology

[0002] Amorphous and nanocrystalline iron cores possess characteristics such as high saturation magnetic induction, high permeability, low loss, good temperature stability, and environmentally friendly manufacturing processes, making them valuable for applications in high-power high-frequency transformers. These cores are made by winding amorphous and nanocrystalline ribbons. The winding process is carried out using a winding machine. (Existing technology: Authorization Publication No. CN) Patent 112967882A discloses an automatic winding machine for producing amorphous and nanocrystalline iron cores, including a vertical plate, a main control box, two sets of limiting blocks, a rotating shaft, a winding block, and a fastening and pressing assembly. The vertical plate has a first fixed plate and a second fixed plate. A first telescopic device on the end face of the first fixed plate is rotatably connected to one set of limiting blocks. The rotating shaft is rotatably connected to the second fixed plate and another set of limiting blocks, and is drively connected to a driving device on the second fixed plate. The outer end face of the winding block has a limiting groove for the two sets of limiting blocks to be inserted into. The winding block has a clamping assembly for holding the amorphous and nanocrystalline strip within the limiting groove. The clamping assembly includes multiple sets of threaded rods, multiple sets of sliding columns, a rotating shaft, and a handwheel. The fastening and pressing assembly is connected to the vertical plate and... The pressing end of the pressing component is attached to the outer circumferential surface of the winding block to press the iron core to be wound. This invention is easy to operate and can meet the needs of winding amorphous and nanocrystalline iron cores of different shapes and thicknesses. During the winding process of amorphous and nanocrystalline iron cores, the winding is guided by the first guide roller and the second guide roller, thereby avoiding the winding deviation phenomenon during the winding process of amorphous and nanocrystalline strip. However, different application environments result in different winding widths of amorphous and nanocrystalline strips for amorphous and nanocrystalline iron cores. The winding guide structure of the amorphous and nanocrystalline strip of this device is fixed and cannot be adjusted according to the width change of the amorphous and nanocrystalline strip, resulting in a low applicability range of the device for winding amorphous and nanocrystalline iron cores. Therefore, we propose an automatic winding machine for amorphous and nanocrystalline iron cores. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide an automatic winding machine for amorphous and nanocrystalline iron cores. This device, through a transmission element, can adjust the anti-deviation guide spacing and move the anti-deviation position horizontally as a whole according to the change in the winding width of the amorphous and nanocrystalline strip of the amorphous and nanocrystalline iron core. This allows the anti-deviation component of the device to prevent deviation when winding amorphous and nanocrystalline iron cores of various widths, improves the applicability of the device to winding amorphous and nanocrystalline iron cores, and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automatic winding machine for amorphous and nanocrystalline iron cores, comprising a winding frame, wherein a winding seat is rotatably connected to the right wall of the winding frame via a rotating shaft one, and two vertically distributed auxiliary rollers are rotatably connected between the left and right walls of the winding frame via a rotating shaft two, and further comprising an anti-deviation mechanism.

[0005] Anti-deviation mechanism: It includes guide grooves, anti-deviation rings, synchronous seats, bidirectional lead screws, fixed shafts, and studs. The guide grooves are respectively opened on the outside of the auxiliary rollers. Two symmetrically distributed anti-deviation rings are slidably connected inside each guide groove. A synchronous seat is rotatably connected between two vertically adjacent anti-deviation rings through a bearing. A bidirectional lead screw is threaded between the two synchronous seats. A fixed shaft is provided inside the bidirectional lead screw. A stud is threaded to the right wall of the winding frame. The right end of the fixed shaft is rotatably connected to the left end of the stud through a bearing. This device, through transmission elements, can adjust the anti-deviation guide spacing and move the overall horizontal position of the anti-deviation component according to the change in the winding width of the amorphous nanocrystalline strip of the amorphous nanocrystalline iron core. This allows the anti-deviation component of the device to prevent deviation when winding amorphous nanocrystalline iron cores of various widths, improving the device's applicability to winding amorphous nanocrystalline iron cores.

[0006] Furthermore, it also includes a microcontroller, which is located outside the winding frame. The input terminal of the microcontroller is electrically connected to an external power supply, making it convenient to control electrical components.

[0007] Furthermore, a brake motor is provided on the right side of the winding frame. The input end of the brake motor is electrically connected to the output end of the microcontroller, and the output shaft of the brake motor is fixedly connected to the right end of the rotating shaft, providing power for the device to wind the amorphous nanocrystalline iron core.

[0008] Furthermore, the outer side of the winding seat is provided with two horizontally distributed spring sheets to fix the initial end of the amorphous nanocrystalline ribbon to the outer side of the winding seat.

[0009] Furthermore, the anti-deviation mechanism also includes a first handwheel and a second handwheel. The second handwheel is located at the left end of the fixed shaft, and the first handwheel is located at the right end of the stud, which facilitates the rotation and adjustment of the bidirectional lead screw and stud in the automatic winding machine for amorphous and nanocrystalline iron cores.

[0010] Furthermore, the anti-deviation mechanism also includes a sealing assembly, which includes a contact ring one, a bellows one, a contact ring two, and a bellows two. The contact ring one is rotatably connected to the left and right ends of the bidirectional lead screw via bearing three. Bellows one is provided between the contact ring one and the adjacent synchronizing seat and between the two synchronizing seats. Bellows one is movably sleeved on the outer end of the bidirectional lead screw. The left and right ends of the stud are rotatably connected to the contact ring two via bearing four. Bellows two is provided between the contact ring two and the winding frame. Bellows two is movably sleeved on the outer end of the stud. This mechanism wraps and seals the exposed parts of the bidirectional lead screw and stud in the automatic winding machine for amorphous and nanocrystalline iron cores.

[0011] Furthermore, each of the two rotating shafts is equipped with a gear on its left end, and the left wall of the winding frame is equipped with two vertically distributed connecting seats. The front side of each connecting seat is equipped with a locking seat through two evenly distributed telescopic columns and springs. The springs are movably sleeved with the outer ends of the adjacent telescopic columns, and the locking seats are installed in cooperation with the adjacent gears. When the amorphous nanocrystalline iron core is wound up, the auxiliary roller is rotated and locked in time, so that the amorphous nanocrystalline strip between the two auxiliary rollers in the automatic winding machine for amorphous nanocrystalline iron core is in a taut state.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This automatic winding machine for amorphous and nanocrystalline iron cores has the following advantages:

This allows the anti-deviation component to prevent deviation during winding of amorphous and nanocrystalline iron cores of various widths, thus improving the applicability of the device for winding amorphous and nanocrystalline iron cores.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This embodiment provides a technical solution: an automatic winding machine for amorphous and nanocrystalline iron cores, including a winding frame 1. A winding seat 4 is rotatably connected to the right wall of the winding frame 1 via a first rotating shaft 3. Two vertically distributed auxiliary rollers 8 are rotatably connected between the left and right walls of the winding frame 1 via a second rotating shaft 7. The machine also includes a microcontroller 2, located outside the winding frame 1. The input end of the microcontroller 2 is electrically connected to an external power source. A brake motor 6 is located on the right side of the winding frame 1. The input end of the brake motor 6 is electrically connected to the output end of the microcontroller 2. The output shaft of the brake motor 6 is fixedly connected to the right end of the first rotating shaft 3. Two horizontally distributed spring plates 5 are provided on the outer side of the winding seat 4. Gears are provided on the left end of the second rotating shaft 7. 10. The left wall of the winding frame 1 is provided with two vertically distributed connecting seats 11. The front side of each connecting seat 11 is provided with a retaining seat 14 through two evenly distributed telescopic columns 12 and springs 13. The springs 13 are movably sleeved with the outer ends of the adjacent telescopic columns 12, and the retaining seats 14 are installed in cooperation with the adjacent gears 10. After the anti-deviation ring 92 is adjusted, the initial end of the amorphous nanocrystalline ribbon is passed through the two auxiliary rollers 8 in a Z-shaped cross shape from bottom to top and attached to the outer side of the winding seat 4. Then, the spring plate 5 is pushed outward, and the initial end of the amorphous nanocrystalline ribbon is squeezed and fixed to the outer side of the winding seat 4 by the spring plate 5. Then, the microcontroller 2 starts the brake motor 6 so that its output shaft drives the rotating shaft 3 to rotate. When the brake motor 6 is energized, the armature inside the brake motor 6 is electromagnetically attracted, making the brake disc rotatable and allowing the brake motor 6 to rotate freely. When the brake motor 6 is de-energized, the electromagnet is de-energized, and the armature is immediately pressed by the spring, causing the brake disc to press against the rear end cover of the motor and stop rotating. Therefore, the output shaft of the brake motor 6 has a self-locking function. The rotating shaft 3 drives the winding seat 4 to rotate, thereby performing the winding operation of the amorphous nanocrystalline ribbon. During the winding process of the amorphous nanocrystalline ribbon, the winding traction force applied by the brake motor 6 (this traction force overcomes the compression force of the spring 13 on the clamping and locking force between the clamping seat 14 and the adjacent gear 10) causes the two auxiliary rollers 8 and the winding seat 4 to rotate. The amorphous nanocrystalline ribbon between the base 4 is in a taut state. The contact resistance between the amorphous nanocrystalline ribbon and the auxiliary roller 8 during the winding and movement of the amorphous nanocrystalline ribbon causes the auxiliary roller 8 to drive the corresponding rotating shaft 7 to rotate. The rotating shaft 7 drives the corresponding gear 10 to rotate. When the iron core amorphous nanocrystalline ribbon is wound up, the microcontroller 2 turns off the brake motor 6. The compression force of the spring 13 causes the card seat 14 to lock the gear 10 in time, so that the two auxiliary rollers 8 stop rotating. Then, the contact resistance between the auxiliary roller 8 and the amorphous nanocrystalline ribbon ensures that the amorphous nanocrystalline ribbon between the two auxiliary rollers 8 is still in a taut state after the iron core amorphous nanocrystalline ribbon is wound up. It also includes an anti-deviation mechanism 9.

[0021] Anti-deviation mechanism 9 includes guide grooves 91, anti-deviation rings 92, synchronization seats 93, double-acting screws 94, fixed shafts 95, and studs 96. Guide grooves 91 are respectively opened on the outer side of the auxiliary rollers 8. Two symmetrically distributed anti-deviation rings 92 are slidably connected inside each guide groove 91. A synchronization seat 93 is rotatably connected between two vertically adjacent anti-deviation rings 92 via a bearing. A double-acting screw 94 is threaded between the two synchronization seats 93. A fixed shaft 95 is located inside the double-acting screw 94. A stud 96 is threadedly connected to the right wall of the winding frame 1. The right end of the fixed shaft 95 is rotatably connected to the left end of the stud 96 via a bearing. Anti-deviation mechanism 9 also includes a first handwheel 97 and a second handwheel 98. The second handwheel 98 is located at the left end of the fixed shaft 95. The right end of the stud 96 is equipped with a handwheel 97. The anti-deviation mechanism 9 also includes a sealing assembly 99, which includes a contact ring 991, a bellows 992, a contact ring 993, and a bellows 994. The contact ring 991 is rotatably connected to the left and right ends of the double-acting screw 94 via bearings 3. Bellows 992 are provided between the contact ring 991 and the adjacent synchronizing seat 93, and between the two synchronizing seats 93. The bellows 992 are movably sleeved on the outer end of the double-acting screw 94. The left and right ends of the stud 96 are rotatably connected to the contact ring 993 via bearings 4. Bellows 994 are provided between the contact ring 993 and the winding frame 1. The bellows 994 are movably sleeved on the outer end of the stud 96. The device is used to adjust the iron... When the core is performing the amorphous nanocrystalline ribbon winding operation, according to the winding width of the amorphous nanocrystalline ribbon, the second handwheel 98 is turned to drive the fixed shaft 95 to rotate. The fixed shaft 95 drives the bidirectional lead screw 94 to rotate. During the rotation of the bidirectional lead screw 94, the two synchronous seats 93 are moved relative to each other through the threaded connection. The synchronous seats 93 drive the corresponding anti-deviation rings 92 to slide along the guide groove 91, thereby adjusting the anti-deviation distance between two horizontally adjacent anti-deviation rings 92 according to the winding width of the amorphous nanocrystalline ribbon. Then, the operator turns the first handwheel 97 to drive the stud 96 to rotate. During the rotation of the stud 96, through the threaded connection between it and the right wall of the winding frame 1, the anti-deviation rings 92 are indirectly driven by the fixed shaft 95 to slide horizontally in the same direction along the corresponding guide groove 91. The device moves so that the two horizontally adjacent anti-deviation rings 92 are vertically aligned with the winding seat 4. During subsequent winding of the amorphous / nanocrystalline strip on the iron core, the two horizontally adjacent anti-deviation rings 92 guide and wind the amorphous / nanocrystalline strip wound on the auxiliary roller 8. The exposed portion of the stud 96 is protected by a second bellows 994, and the exposed portion of the bidirectional lead screw 94 is protected by a first bellows 992. Through transmission elements, the device can adjust the anti-deviation guide spacing and move the overall horizontal position of the anti-deviation components according to changes in the winding width of the amorphous / nanocrystalline strip on the amorphous / nanocrystalline iron core. This allows the anti-deviation components to prevent deviation during winding of amorphous / nanocrystalline iron cores of various widths.This improves the applicability of the device for winding amorphous and nanocrystalline iron cores.

[0022] The working principle of the automatic winding machine for amorphous and nanocrystalline iron cores provided by this utility model is as follows: When using the device to wind amorphous and nanocrystalline strips for the iron core, firstly, according to the winding width of the amorphous and nanocrystalline strip, turn handwheel 2 98 to drive the fixed shaft 95 to rotate. The fixed shaft 95 drives the bidirectional lead screw 94 to rotate. During the rotation of the bidirectional lead screw 94, the two synchronous seats 93 move relative to each other through the threaded connection. The synchronous seats 93 drive the corresponding anti-deviation rings 92 to slide along the guide groove 91, thereby adjusting the anti-deviation distance between two horizontally adjacent anti-deviation rings 92 according to the winding width of the amorphous and nanocrystalline strip. Then, the operator turns handwheel 1 97 to drive the stud 96 to rotate. During the rotation of the stud 96, it moves relative to the winding frame 1. The threaded connection between the walls allows the anti-deviation rings 92 to slide horizontally in the same direction along the corresponding guide grooves 91 via the fixed shaft 95, thus aligning the two horizontally adjacent anti-deviation rings 92 vertically with the winding seat 4. During the subsequent winding of the amorphous nanocrystalline ribbon on the iron core, the two horizontally adjacent anti-deviation rings 92 guide and wind the amorphous nanocrystalline ribbon wound on the auxiliary rollers 8. After the anti-deviation rings 92 are adjusted, the initial end of the amorphous nanocrystalline ribbon is passed through the two auxiliary rollers 8 in a Z-shaped cross pattern from bottom to top and adhered to the outer surface of the winding seat 4. Then, the spring plate 5 is pushed outwards, pressing and fixing the initial end of the amorphous nanocrystalline ribbon to the outer surface of the winding seat 4. Finally, the microcontroller 2 activates the braking mechanism. Motor 6 drives the rotating shaft 3 to rotate via its output shaft. When brake motor 6 is energized, the armature inside brake motor 6 is electromagnetically attracted, making the brake disc rotatable and allowing brake motor 6 to rotate freely. When brake motor 6 is de-energized, the electromagnet is de-energized, and the armature is immediately held in place by the spring, pressing the brake disc against the rear end cover of the motor and stopping rotation. Therefore, the output shaft of brake motor 6 has a self-locking function. Rotating shaft 3 drives the winding seat 4 to rotate, thereby performing the winding operation of amorphous nanocrystalline ribbon. During the winding process of amorphous nanocrystalline ribbon, the winding traction force applied by brake motor 6 (this traction force overcomes the compression force of spring 13 on the locking force between the card seat 14 and the adjacent gear 10) causes the two auxiliary rollers 8 and the winding seat 4 to rotate. The amorphous nanocrystalline ribbon between seats 4 is in a taut state. The contact resistance between the amorphous nanocrystalline ribbon and the auxiliary rollers 8 during its winding movement causes the auxiliary rollers 8 to drive the corresponding rotating shaft 7 to rotate. The rotating shaft 7 then drives the corresponding gear 10 to rotate. After the amorphous nanocrystalline ribbon is wound up, the microcontroller 2 shuts off the brake motor 6. The compression force of the spring 13 causes the clamping seat 14 to lock the gear 10 in time, stopping the rotation of the two auxiliary rollers 8. Furthermore, the contact resistance between the auxiliary rollers 8 and the amorphous nanocrystalline ribbon ensures that even after the amorphous nanocrystalline ribbon is wound up, the amorphous nanocrystalline ribbon between the two auxiliary rollers 8 remains taut. The exposed portion of the stud 96 is protected by the corrugated tube 994.The exposed portion of the bidirectional lead screw 94 is protected by a bellows-992.

[0023] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be NY8A050D, the brake motor 6 can be YEJ6324, and the microcontroller 2 controls the operation of the brake motor 6 using methods commonly used in the prior art.
