Embodiment Construction
[0060]The invention provides a winding device and a winding method for a single-cycle rectangular or almost rectangular voice coil. The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings, so as to make it easier to understand and grasp.
[0061] Winding devices with a single round of rectangular or quasi-rectangular voice coils, such as figure 1 As shown, the wire inlet unit 1100 for enameled wire introduction, and the wire winding unit 1200 for direct winding of a rectangular or quasi-rectangular voice coil.
[0062] Among them, such as figure 2 As shown, the wire inlet unit 1100 includes a wire outlet guide mechanism 1110 with displacement in three directions of X axis, Y axis and Z axis, and the wire outlet nozzle 1111 of the wire outlet nozzle mechanism 1110 has a rotational displacement around its own axis. Therefore, the outlet guide nozzle 1111 can realize the adjustment of any displacement and ...

The invention discloses a winding device and method for a rectangular or rectangular-like voice coil of a single circle. The winding device includes an inlet wire unit for guiding enameled wires in the omnibearing mode and a winding unit for winding a rectangular or rectangular-like voice coil of a single circle. The invention can realize the direct molding of a rectangular or rectangular-like voice coil without shaping, and the voice coil is high in precision and stable in magnetic flux. There are two winding modes, namely, inner wire incoming and outer wire incoming. The line unit can be used to adjust the entering angle, so as to facilitate guiding fixation of the enameled wires. The device and the method achieve winding of a special-shaped voice coil, and the applicability of the device is expanded. A temperature control unit is designed to make bonding between the enameled wires of the voice coil stable and reliable. The overall design is simple, the operation is convenient and reliable, the pass rate of direct molding products is high, and the popularization and application is easy.
Description
technical field [0001] The invention relates to a winding device for a voice coil, in particular to a winding device and a winding method for a single-circle rectangular or almost rectangular voice coil, belonging to the technical field of voice coil winding. Background technique [0002] Electronic devices with speakers and receivers, such as mobile phones, laptops, desktop computers, and smart watches, will involve the installation of voice coils. [0003] Due to the improvement of the acoustic requirements of electronic equipment due to the update of current electronic products, such as better signal-to-noise ratio, higher sensitivity, etc., the bottleneck of the assembly accuracy of the current acoustic horn (speaker and receiver) comes from the tolerance deviation of the coil. Large, unable to meet the further improvement of performance. [0004] The current winding method of the voice coil is to convert the circular coil into a square coil by stretching the circular c...
