Glue path detection method for glue with fluorescence effect

Abstract

The invention relates to a glue path detection method for glue with a fluorescence effect. The method comprises the steps that a UV light source is used for irradiating to obtain an image of a glue path; the image is processed; an overflow glue detection mode and / or a first glue breaking / dripping detection mode and / or a second glue breaking / dripping detection mode are / is carried out, wherein the overflow glue detection mode is used for detecting whether glue overflow abnormity exists in the glue path or not, the first glue breaking / dripping detection mode is used for detecting whether glue breaking abnormity and glue dripping abnormity exist in the glue path where the edge of the glue path is located or not, and the second glue breaking / dripping detection mode is used for detecting whether glue breaking abnormity and glue dripping abnormity exist in the glue path where the corner of the glue path is located or not. According to the invention, whether the glue path of the glue coated with the fluorescent effect has the defects of glue overflow, glue breaking and glue dripping can be intelligently detected, manual detection is avoided, and the detection efficiency and accuracy are high.

Description

technical field [0001] The invention belongs to the technical field of glue path detection, and in particular relates to a glue path detection method of glue with fluorescent effect. Background technique [0002] In acoustic devices (such as loudspeakers), dispensing is widely used. Dispensing is a process, also known as sizing, gluing, glue pouring, glue dropping, etc., which is to apply glue, oil or other liquids, potting, Drop it on the product, so that the product can play the role of sticking, potting, insulating, fixing, and smooth surface. [0003] The diaphragm and DOME (the top of the ball) are the core parts of the entire acoustic device. The DOME of the acoustic device is mainly divided into two types: one is a thin sheet of aluminum material, and the other is a plastic material in the middle with tin coating on both sides (abbreviation, tin coating Layer DOME). [0004] At present, tin-coated DOME is widely used. The diaphragm is a kind of transparent plastic. ...

Problems solved by technology

[0005] Conventional glue path detection methods can detect glue path defects with regular shape tracks and single-layer glue path defects. Since DOME is glued on both sides, the glue path trajectory of the second layer of glue is affected by the glue path trajectory of the first layer of glue. The glue track is superimposed, the shape of the glue track of the second layer of glue is irregular, and the detection is difficult

In the prior art, general intelligence relies on manual detection, which has the disadvantages of high detection cost, low efficiency, large task load, and low detection accuracy.
