Abstract
Description
Technical Field
[0001] This utility model relates to the field of loudspeaker manufacturing technology, specifically to a voice coil coating device for loudspeaker manufacturing. Background Technology
[0002] In loudspeaker manufacturing, the adhesive application process for the voice coil is crucial. As one of the core components of a loudspeaker, the quality of the adhesive application directly affects the loudspeaker's performance and lifespan. Traditional voice coil adhesive application methods often rely on manual operation or simple mechanized equipment, which have several shortcomings.
[0003] For example, Chinese patent CN214975300U discloses a voice coil coating device for loudspeaker production. This patent automates the coating process by designing a coating device that includes an outer ring rotation device, a rocker arm device, a rocker arm drive device, a voice coil fixing device, a main frame, and an automatic glue spraying device. This device uses a crank-rocker mechanism to drive the motor in a cyclical motion, ensuring the uniformity of the glue spraying and effectively solving the problems of low automation and low efficiency in traditional coating methods. Although the coating device proposed in this patent improves coating efficiency and uniformity to some extent, it may still have some shortcomings in practical applications. For example, this patent may not fully consider how to more precisely control the amount of glue applied to ensure consistent glue thickness on each voice coil, thereby further improving the sound quality of the loudspeaker. Furthermore, with the continuous development of the loudspeaker manufacturing industry, higher demands are placed on the flexibility and adaptability of coating devices, requiring them to easily handle the coating needs of voice coils of different specifications and sizes. Therefore, we propose a voice coil coating device for loudspeaker production. Utility Model Content
