Description

Technical Field

[0002] Toroidal transformers, widely used as power transformers and isolation transformers in electronic devices, are renowned for their high electrical efficiency, low noise, and compact structure. However, existing toroidal transformers, in terms of size and specifications, cannot meet the miniaturization requirements of circuit boards for the specialized needs of cochlear implants.

[0003] Traditional toroidal transformer production typically utilizes specialized automated winding equipment, such as toroidal winding machines, to improve production efficiency and product quality. These machines produce compact, small, and high-strength coils, making them suitable for most toroidal transformer production. However, existing winding equipment cannot meet the production requirements of the miniature toroidal transformers used in cochlear implant circuit boards due to the extremely small magnetic ring size and limited wire diameter range.

This manual winding process presents several technical challenges: First, securing the miniature magnetic ring and wire is difficult, and tweezers are currently used to assist in securing the winding. Second, precise control of the number of turns is required to maintain a uniform magnetic field distribution. Furthermore, due to frequent changes in winding angles and viewing angle limitations, the winding process is discontinuous and requires many repetitive movements, resulting in difficulty, low efficiency, and the risk of accidental damage and waste of wire.

[0041] The base assembly 1 includes a base 11, a rotating seat 12 and a fixed plate 13. A concave spherical hole 111 is provided at the top center of the base 11. The rotating seat 12 fits inside the concave spherical hole 111 and is rotatably connected to the inner wall of the concave spherical hole 111. A spherical boss 112 is provided at the bottom center of the base 11. The fixed plate 13 is bowl-shaped and covered on the boss 112.

The rotating seat 12 and the fixed plate 13 are connected by a fastening bolt 16. A slide groove 15 is provided on the left and right sides of the front of the rotating seat 12, and a buckle column 14 is installed inside the slide groove 15.

[0042] The base 11 can be placed firmly and horizontally on a desktop or other workbench. The concave spherical design on the front surface can adjust a certain viewing angle. A large angle adjustment hole is provided in the center of the base 11, which is communicated with the boss 112. The base 11, the fixed plate 13 and the rotating seat 12 are connected and clamped by a fastening bolt 16 to achieve fixation and realize angle adjustment.

A small-diameter guide rod 161 is provided on the top of the fastening bolt 16, which facilitates the alignment and connection of the fastening bolt 16, the fixed plate 13 and the rotating seat 12 without affecting the threaded connection. When the rotating seat 12 and the fixed plate 13 are connected by the fastening bolt 16 and the bottom of the fastening bolt 16 is against the bottom of the fixed plate 13, the inclination angle of the rotating seat 12 is fixed; when the fastening bolt 16 is rotated downward until the bottom is no longer in contact with the fixed plate 13, the rotating seat 12 can be adjusted in angle. During operation, the base assembly 1 is placed on a tabletop. By loosening the fastening bolts 16 and adjusting the desired angle of the rotating base 12 and the fixed plate 13 simultaneously, a free adjustment of 0-30 degrees is achieved. The initial adjustment is to a horizontal angle. Finally, the fastening bolts 16 are tightened to maintain the adjusted angle. In addition, in this embodiment, the bottom of the base 11 is provided with four anti-slip pads to ensure that the entire base 11 is stable and does not move during adjustment.

[0043] The wire buckle column 14 includes a head 141 and a bottom column 142. The longitudinal section of the bottom column 142 is a concave structure. The bottom of the bottom column 142 is slidably connected to the slide groove 15. The top of the head 141 is provided with a cross cutout 143 for embedding and fixing the wire. The upper part of the bottom column 142 is slidably connected to the head 141.

[0044] The wire-grip post 14 is a TPU post with a cross-cut notch 143 for inserting and securing wires. A threaded hole is provided at the bottom of the head 141 for locking and securing. The top of the base post 142 has threads that mate with the threads of the head 141. The base post 142 can slide in the chute 15 at a variable distance, allowing for an adjustable wire length range of 10-25mm. The entire base assembly 1 is made of stainless steel to ensure precision and durability.

[0045] The slide rail assembly 2 includes a left slide 21 and a right slide 22, which are combined to form a single slide rail. A quick-installation slot 121 is defined at the top center of the rotating base 12, which is slidably connected to the slide rail. A slideway 23 is also provided between the left and right slides 21 and 22. The entire slide rail assembly 2 is constructed of stainless steel to ensure precision and durability. The center portion features an I-shaped slide rail design, and the lower portion includes miniature bearings 7 on each side for mounting rollers.

[0046] The slider assembly 3 includes a left slider 31 and a right slider 32 . The left slider 31 and the right slider 32 are combined to form a slider as a whole. The slider as a whole slides in the slideway 23 .

[0047] The slide rail assembly 2 also includes a pressure adjusting screw 24. The slide rail as a whole is provided with a threaded hole communicating with the slideway 23. The pressure adjusting screw 24 is threadedly connected to the threaded hole. The pressure adjusting screw 24 and the slider as a whole are penetrated. The front end of the pressure adjusting screw 24 is sleeved with a pressure spring 25. The two ends of the pressure spring 25 are in contact between the pressure adjusting screw 24 and the slider as a whole.

[0048] The pressure adjustment screw 24 includes a threaded rod 241 and a straight rod 242. The diameter of the straight rod 242 is smaller than that of the threaded rod 241. The pressure spring 25 is sleeved on the straight rod 242. The two ends of the pressure spring 25 are in contact between the threaded rod 241 and the entire slider.

[0049] The pressure-adjusting screw 24 and pressure spring 25 generate a certain force, enabling the slider assembly 3 to slide a distance of 0-5 mm. The threaded rod 241 adjusts the distance forward and backward, while the straight rod 242 fixes the pressure spring 25. The pressure spring 25 can freely expand and contract on the straight rod 242. The reaction force after compression generates an adjustable force within the range of 3-10 N. This reaction force pushes the slider to press against the magnetic ring 6, while also providing a certain buffering force.

[0050] The winding adjustment assembly 4 includes a wheel axle 41 rotatably connected to the slider as a whole, and a primary wheel 42 and a secondary wheel 43 are respectively installed on both sides of the slider as a whole. The primary wheel 42 and the secondary wheel 43 are both coaxially connected to the wheel axle 41, and the outer walls of the primary wheel 42 and the secondary wheel 43 are provided with a 0-degree indicator mark. Before winding, the primary wheel 42 or the secondary wheel 43 is first rotated so that the 0-degree indicator mark is in a horizontal or vertical direction, and the primary wheel 42 or the secondary wheel 43 is rotated to perform secondary or primary winding on the magnetic ring 6. When the 0-degree indicator mark rotates to the reset state, it indicates that the magnetic ring 6 has completed 360° winding. A driving wheel 44 is sleeved on the middle part of the wheel axle 41, and a plurality of tooth grooves 45 are provided on the inner side surfaces of the primary wheel 42 and the secondary wheel 43. Spring ejectors 33 are fixedly installed on the sides of the left slider 31 and the right slider 32. The tooth grooves 45 are engaged with the spring ejectors 33, and the spring ejectors 33 are used to adjust the limit of the tooth grooves 45 for winding the angle.

[0051] The winding adjustment assembly 4 is primarily used to adjust the winding angle during winding to achieve the turns ratio between the primary and secondary windings. This allows for continuous winding while adjusting the angle. By replacing the primary and secondary pulleys 42 and 43, products of varying specifications with different turns ratios can be wound. To ensure durability and precision, the entire winding adjustment assembly 4 is made of stainless steel.

[0052] The driving wheel 44 is mounted through the hexagonal mounting position in the middle of the wheel axle 41. The driving wheel 44 is also a TPU wheel. The wheel axle 41 is installed in the mounting hole at the bottom of the slider assembly 3, mating with the miniature bearing 7 and fixed in place. The primary wheel 42 and the secondary wheel 43 have "D"-shaped holes in their centers that mate with the rectangular portion on the outside of the wheel axle 41.

[0053] The left and right heads 141 of the axle 41 are provided with screw holes for securing the primary wheel 42 and the secondary wheel 43. Align the primary wheel 42 with the outer "D"-shaped shaft of the axle 41 and install it, aligning the spring ejector pin 33 with the tooth groove 45. Align the secondary wheel 43 with the outer "D"-shaped shaft of the axle 41 and install it, aligning the spring ejector pin 33 with the tooth groove 45. Secure the screws on the left and right sides of the axle 41.

[0054] The follower assembly 5 includes two follower shafts 51 vertically arranged one above the other. The two ends of the follower shafts 51 are rotatably connected to the interior of the entire slide rail. A follower wheel 52 is sleeved on the center of the follower shaft 51. The receiving opening is formed between the follower wheel 52 and the driving wheel 44. Both the driving wheel 44 and the follower wheel 52 are concave wheels, and friction protrusions are provided on the inner groove surface. The main function of the follower assembly 5 is to rotate synchronously with the rotation of the primary wheel 42 and the secondary wheel 43 as the driving wheel 44 adjusts the winding angle of the magnetic ring 6. It is mainly composed of the follower shaft 51 and the follower wheel 52. The follower wheel 52 is also configured as a TPU wheel. Both the driving wheel 44 and the follower wheel 52 are configured as concave wheels. A convex surface is provided in the groove to increase friction. At the same time, the groove width is designed according to the product appearance. The follower wheel 52 is fixed to the lower part of the slide rail assembly 2 to play a follower role.

[0055] The current primary winding is 5 turns and the secondary winding is 30 turns. To ensure uniform distribution of the magnetic field, the winding also needs to be uniformly distributed. Taking the primary as an example: 5 turns, i.e. 360°, should be wound with a 72° interval between the two turns; taking the secondary as an example: 30 turns, i.e. 360°, should be wound with a 12° interval between the two turns. Therefore, the interval angle of the tooth portion 45 of the primary wheel 42 is set to 72°, and the interval angle of the tooth portion 45 of the secondary wheel 43 is set to 12°.
