Method for accelerating agglutination and curing of loudspeaker cone corrugated rim and loudspeaker bracket by hot-pressing forming machine

Abstract

The invention relates to a method for accelerating the agglutination and curing of a loudspeaker cone corrugated rim and a loudspeaker bracket by a hot-pressing forming machine. The hot-pressing forming machine is adopted. The method comprises that: the loudspeaker bracket is arranged in a lower die; the loudspeaker cone corrugated rim is aligned with and arranged on the edge of the bracket of the loudspeaker, and an adhesive is smeared on the lower surface of the edge of the loudspeaker cone corrugated rim and / or the upper surface of the edge of the loudspeaker bracket; a sliding seat drivesa thermally conductive substrate to move downwards together with an upper die, the upper die presses the loudspeaker cone corrugated rim and the edge of the loudspeaker bracket, the thermally conductive substrate is electrified and heated, and the pressure of the adhesive between the loudspeaker cone corrugated rim and the loudspeaker bracket is preserved for a certain time at a temperature; and the sliding seat slides upwards, and the loudspeaker bracket and the loudspeaker cone corrugated rim which are agglutinated are taken out. By the method, the loudspeaker cone corrugated rim and the loudspeaker bracket can be rapidly cured after being agglutinated, the adhesive between the two parts is uniform in thickness, and has a good coverage track and consistence, the bonding strength and surface smoothness between the two parts are ensured, and the adhesive curing time is shortened.

Description

technical field [0001] The invention belongs to the technical field of loudspeaker assembly, in particular to a method for accelerating the gluing and curing of a loudspeaker cone ring and a bracket by using a hot press forming machine. Background technique [0002] As a sounding body, the speaker must be tightly combined with each other, otherwise the speaker will have abnormal sound or even be unusable. At present, the most commonly used bonding method between speaker components is to use adhesives to bond, and the components of the same or different materials of the speaker are firmly connected together by virtue of the adhesive force generated by the adhesive on the solid surface. Generally speaking, for each bonding part of different components, it is necessary to select various suitable adhesives. The traditional method of gluing and curing the loudspeaker cone ring and the bracket is: use an ordinary glue applicator to inject glue on the designated position of the bra...

AI Technical Summary

Problems solved by technology

However, due to factors such as the pressure of the glue injection machine, the thickness of the glue injection part is not easy to be uniform, and the trajectory of the adhesive is inconsistent, which may easily cause the adhesive to overflow and contaminate other parts, resulting in abnormal sound when the speaker is working; The curing time is also relatively long, which is not conducive to the rapid assembly and production of products
