Coil winding template and ultra-small volume coil forming method

Abstract

The invention provides a coil winding template and an ultra-small volume coil forming method. The coil winding template comprises a coil framework, a clamping structure and a shaping sleeve; the clamping structure is fixedly arranged on the lower portion of the coil framework; the shaping sleeve is arranged outside the coil framework in a sleeving mode; a coil winding groove is formed in the coil framework; and the coil framework is made of a dissoluble material. The coil framework is made of the dissoluble material, and after the coil framework is dissolved in a dissolving solution, and the situations that a copper wire is snapped, and an insulating layer is broken due to rubbing in a demolding process, clamping deformation and dragging deformation often occur in the demolding process, the winding copper wire is often clamped by gaps among metal parts, and the copper wire is damaged and broken due to clamping, are avoided. According to the coil winding template, firstly, a coil is shaped through an adhesive, so that the strength of the coil is improved, then the wound coil is shaped through the shaping sleeve, so that high-precision forming of the coil with the ultra-small size ( the diameter is as small as 2 mm) can be achieved.

Description

technical field [0001] The invention belongs to the technical field of motor coil manufacturing technology, and in particular relates to a coil winding template and an ultra-small-volume coil forming method. Background technique [0002] For laser systems used in satellite communications, the optical path adjustment device is required to be small in size, light in weight, and can be controlled with high precision. For this reason, a satellite overall unit proposed to use an optical path adjustment mechanism with an outer diameter of only 5mm to replace the existing large-scale laser mirror. The optical path adjustment mechanism mainly consists of lenses with an outer diameter of 5mm and four voice coils with an outer diameter of 2.5mm and a height of 3mm. Composed of motors, the yaw action of the lens is realized through the cooperation of the actuation modes between the four voice coil motors. Among them, the coil used in the voice coil motor is composed of two sets of hol...

AI Technical Summary

Problems solved by technology

[0004] (1) The diameter of the wire used for the coil is usually less than 0.1mm, and the copper wire may be broken or scratch the insulation during the demoulding process;

[0005] (2) The curing strength of the coil itself is extremely low, and clamping deformation, dragging deformation, etc. often occur during the demolding process;

[0006] (3) The gap between metal parts often jams the winding copper wire, causing the copper wire to be pinched and broken
