[0002] As a power transformer and isolation transformer widely used in electronic devices, the ring transformer is known for its high electrical efficiency, low noise and compact structure. However, for the special requirements of cochlear implants, the existing ring transformers cannot meet the miniaturization requirements of the circuit board in terms of volume and specifications.

[0003] Traditional production of ring transformers usually adopts special automatic wire arranging and winding equipment, such as a ring winding machine, to improve production efficiency and product quality. These devices can produce coils with a compact structure, small volume and high strength, which are suitable for the production of most ring transformers. However, for the micro-ring transformer in the cochlear implant circuit board, due to its extremely small magnetic ring size and extremely limited wire diameter range, the existing winding equipment cannot meet its production requirements.

[0004] At present, the winding of micro-ring transformers mainly relies on manual operation under a microscope environment. There are multiple technical problems in the manual winding process: First, it is difficult to fix the micro-magnetic ring and wire, and currently, tweezers are used for auxiliary fixation; second, precise control of the number of winding turns is required to maintain uniform magnetic field distribution; due to the frequent change of winding angles and viewing angle limitations, the winding process is discontinuous and there are many repetitive actions, resulting in high winding difficulty, low efficiency, and easy accidental damage and waste of wire.

[0044] The coil winding steps of the micro-ring transformer are as follows:

[0045] S1: Place the magnetic ring 6 into the accommodation opening, rotate the pressure adjustment screw 24 to push the entire slider forward, so that the follower wheel 52 and the driving wheel 44 clamp the magnetic ring 6;

[0050] S6: Repeat steps S4 and S5 to wind the magnetic ring 6 successively. The interval angle between adjacent turns is the same. After the magnetic ring 6 rotates 360° (i.e., winds 30 turns), the secondary winding is completed. Fix the remaining enameled wire on the right-lower wire clamping post 14, and the secondary winding of the micro-ring transformer is wound.

[0051] S7: Wind the primary winding of the transformer. Fix one end of the primary enameled wire on the upper-left wire clamping post 14 of the rotating base 12 and lock the enameled wire.

[0052] S8: Rotate the primary wheel 42 to make the 0-degree indication mark point horizontally or vertically. Then pass the enameled wire through from the left side to the right side and then back to the left side. The first turn is wound.

[0053] S9: Rotate the primary wheel 42 to make the spring ejector pin 33 pop into the next tooth groove part 45. The driving wheel 44 drives the magnetic ring 6 to rotate synchronously, completing a rotation of one scale (72°). Pass the enameled wire through from the left side to the right side and then back to the left side. The second turn is wound.

[0054] S10: During winding, observe the winding state through a microscope, adjust the winding viewing angle of the base assembly 1 in real time, and at the same time adjust the pressure adjusting screw 24 according to the winding situation to adjust the winding pressure, and observe the winding tightness and arrangement in real time.

[0055] S11: Repeat steps S9 and S10 to wind the magnetic ring 6 successively. The interval angle between adjacent turns is the same. After the magnetic ring 6 rotates 360° (i.e., winds 5 turns), the primary winding is completed. Fix the remaining enameled wire on the upper-right wire clamping post 14, and the primary winding of the micro-ring transformer is wound.
