Description

Technical Field

[0001] The utility model relates to the field of production and manufacturing of magnetic ring inductors, in particular to a magnetic ring rotating mechanism used in a single-wire winding automatic hooking machine. Background Art

[0002] The wound magnetic ring is a core component of toroidal inductors. To meet the varying requirements of toroidal inductors, the design of the wound magnetic ring must be tailored to the specific needs of the inductor. Toroidal inductors are typically categorized as differential-mode and common-mode inductors. Differential-mode inductors are those wound with a single wire wound throughout the toroid, while common-mode inductors are those wound with two wires wound in parallel or separately. To ensure uniform winding of the wire around the toroid and avoid overlap, which can affect the quality of the inductor, the winding process typically requires simultaneous rotation. Currently, single-wire winding equipment on the market utilizes a robotic arm instead of manual winding. Rotary winding typically employs a more complex mechanical structure to drive the entire robotic arm around the toroid to achieve uniform winding. This structure results in a large overall device size, and the large winding stroke can easily cause the wire to become entangled with other internal mechanical structures. Utility Model Content

[0004] The technical solution adopted by the present invention is as follows: the present invention includes a base and three groups of rotational positioning modules arranged on the base, the rotational positioning module includes a slide rail, a mounting plate slidingly matched with the slide rail, a rotational driving unit arranged on the mounting plate, and a rotational positioning wheel arranged at the front end of the mounting plate and transmission-connected to the rotational driving unit, a translational driving unit is also provided on one side of the slide rail and drives the mounting plate to slide on the slide rail, the connecting line of the ends of the three groups of slide rails forms an equilateral triangle, and the contact points of the three groups of rotational positioning wheels coincide with the center point of the equilateral triangle.

[0005] Furthermore, the rotary positioning wheel is rotatably connected to the front end of the mounting plate through a rotary bearing, a first pulley is provided at the bottom of the rotary bearing, a second pulley is provided on the output shaft of the rotary drive unit, and the first pulley and the second pulley are connected by a transmission belt.

[0006] Furthermore, at least two groups of sliders are provided on the slide rail, the sliders are transmission-connected to the translation drive unit, the mounting plate is fixedly provided on the two groups of sliders, a stop block is also provided at the end of the slide rail, and a buffer spring is provided between the stop block and the mounting plate.

When the hooking machine starts to wind a single line, the magnetic ring needs to be rotated to ensure that the single line is evenly wound around the magnetic ring.

Therefore, the present invention has a simple structure, effectively simplifies the internal structure of the equipment, and improves the precision of rotary winding processing.

[0012] like Figure 1 and Figure 2As shown, the present invention includes a base 1 and three sets of rotary positioning modules arranged on the base 1. The rotary positioning module includes a slide rail 2, a mounting plate 3 that slides with the slide rail 2, a rotary drive unit 4 arranged on the mounting plate 3, and a rotary positioning wheel 5 arranged at the front end of the mounting plate 3 and connected to the rotary drive unit 4. A translation drive unit 6 is also provided on one side of the slide rail 2 to drive the mounting plate 3 to slide on the slide rail 2. The line connecting the ends of the three sets of slide rails 2 forms an equilateral triangle, and the contact points of the three sets of rotary positioning wheels 5 coincide with the center point of the equilateral triangle. A protective cover plate 14 is provided at the bottom of the front half of the mounting plate 3. The protective cover plate 14 covers the first pulley 8 and the second pulley 9. A gear ring 15 is also provided on the rotary positioning wheel 5. The gear ring 15 is made of high-strength rubber. In the present invention, the translation drive unit 6 and the rotary drive unit 4 can adopt transmission modules such as stepping motors or cylinders. The present invention clamps and positions the magnetic ring through three groups of rotary positioning modules. When the feeding mechanism clamps the magnetic ring and places it in the position to be surrounded, the three groups of translation drive units 6 are driven simultaneously to drive the mounting plate 3 to move toward the center point of the equilateral triangle on the slide rail 2 until the magnetic ring is clamped and fixed. Since the end connection line of the three groups of slide rails 2 forms an equilateral triangle in the present invention, when the three groups of rotary positioning wheels 5 are pushed to clamp the magnetic ring, a three-point clamping force is applied to the magnetic ring, and the clamping stability force is greatly improved. In addition, the gear sleeved on the rotary positioning wheel 5 Ring 15 utilizes the elastomeric material and gear structure to further enhance the friction force on the magnetic ring, better clamp the magnetic ring and drive it to rotate; when the hook line machine starts to wrap a single line, the magnetic ring needs to be rotated to ensure that the single line is evenly wrapped around the magnetic ring, and the three groups of the rotation drive units 4 are started at the same time, driving the rotation positioning wheel 5 to rotate, driving the magnetic ring to rotate according to the required angle, replacing the traditional mechanical arm rotation structure with a simpler internal structure, effectively simplifying the equipment structure, and replacing the mechanical arm revolution with the self-rotation of the magnetic ring, reducing the possibility of the line being entangled with the internal structure of the equipment during winding.

[0013] In the present invention, the rotary positioning wheel 5 is rotatably connected to the front end of the mounting plate 3 via a rotary bearing 7. A first pulley 8 is provided at the bottom of the rotary bearing 7. A second pulley 9 is provided on the output shaft of the rotary drive unit 4. The first pulley 8 and the second pulley 9 are connected by a transmission belt 10. At least two sets of sliders 11 are provided on the slide rail 2. The sliders 11 are transmission-connected to the translation drive unit 6. The mounting plate 3 is fixedly mounted on the two sets of sliders 11. A stop block 12 is also provided at the end of the slide rail 2. A buffer spring 13 is provided between the stop block 12 and the mounting plate 3. In this embodiment, a plurality of positioning posts 16 are also provided at the bottom of the base 1.
