Description

Technical Field

[0001] This utility model relates to the field of dispensing equipment technology, specifically a universal dispensing equipment for assembling speaker components. Background Technology

[0002] Loudspeakers, as electronic devices that convert electrical energy into sound energy, are widely used in various electronic devices. Common loudspeakers can be classified into moving-coil loudspeakers, electrostatic loudspeakers, piezoelectric loudspeakers, and permanent magnet loudspeakers according to their sound-producing principles. The universal dispensing equipment commonly used in loudspeaker component assembly is the loudspeaker dispensing machine or circular dispensing machine. Its core function is to accurately dispense adhesives onto round or curved parts, and it is suitable for various types of adhesives such as red glue, silicone, and epoxy resin.

[0003] For example, the online precision glue injection equipment and method for sound effect loudspeakers disclosed in the authorization announcement number CN115608569B relates to the field of sound effect loudspeaker glue injection technology. It includes a worktable, the top of which has a placement slot, and electromagnets are evenly spaced inside the placement slot. The top of the worktable outside the placement slot is provided with a bonding processing component. The bonding processing component includes a motor base, an adjustment frame and a bonding frame. The motor base is fixedly connected to the top of the worktable, and the bonding frame is fixedly connected to the top of the adjustment frame. A heating plate is fixedly connected inside the bonding frame near the opening end.

[0004] Although it achieves the effect of online precision glue injection equipment and glue injection method for sound effect loudspeakers, it can rinse the softened liquid glue inside and outside the glue injection nozzle to ensure that the inside and outside of the glue injection nozzle are in a clean state, and avoid the subsequent use of the glue due to the solidification of the liquid glue attached inside and outside falling into the glue injection point, which would cause the connection between the parts and the speaker shell to be not firm enough.
