Description
Technical field
The present invention relates to glue and its coating art, specially a kind of loudspeaker glue coating and its coating process.
Background technique
Coating technique is that glue, oil or other liquid applicators, encapsulating, point are dripped on product, allow product play paste,
Encapsulating, insulation, fixation, the effects of surface is smooth, translucency is good, at present in electronic liquid crystal display or electric paper book ink screen industry
In be frequently necessary to carry out glue application, two planar products are fit together, in this coating process, used glue is logical
It is often curable glue, such as polyurethane coating, polyurethane acroleic acid gluing, epoxy polyurethane gluing etc., in use, will fitting
Product solidify (ultraviolet light solidification), after moisture-curable by UV, the bonding for enabling product formation consolidate, in the assembling process of loudspeaker
In, numerous parts are also required to fix using glue, and the coating quality of glue directly influences the quality of loudspeaker and the sound quality of loudspeaker,
Since the glue being coated with is liquid shape, during fitting, glue can be spread under pressure to material edge, this will lead
It causes the edges of regions of glue application to spread, and it is undulated to cause the edge of glue bearing areas to be formed, that is, there is apparent overflow
Glue phenomenon, glue application technique cannot optimize, and coating quality is bad.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the existing defects, provides a kind of loudspeaker glue coating and its coating work
