Description

Technical Field

[0001] The utility model relates to the technical field of loudspeaker voice coil processing, in particular to a positionable loudspeaker voice coil assembly machine. Background Art

[0002] The speaker voice coil is the core of the speaker's power unit and an important component of the electrodynamic speaker's mechanical wave system. The voice coil converts electrical signals into mechanical vibrations through the coil, thereby generating sound. During the production and processing of speaker voice coils, a speaker voice coil assembly machine is required to bond and assemble the voice coil and diaphragm. However, current speaker voice coil assembly machines still have the following shortcomings:

[0003] For example, patent document CN206879101U discloses a speaker voice coil and diaphragm assembly device. This speaker voice coil and diaphragm assembly device uses a glue applicator to apply glue and bond the voice coil and diaphragm together for assembly. After the glue dries, the elastic sleeve is pinched and separated from the voice coil, and the second seat is removed from the first seat. This prevents the voice coil and diaphragm from pulling against each other and preventing them from skewing, thereby improving the sound quality of the speaker, reducing distortion, and increasing production throughput. However, it is not convenient for automatically locating the assembly position of the voice coil, which can easily lead to low assembly quality and efficiency.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and a positionable loudspeaker voice coil assembly machine is proposed. Utility Model Content
