Technical Field

The invention relates to the technical field of loudspeaker production equipment, in particular to an auxiliary glue scraping device for loudspeaker production.

Background

The gluing process of loudspeaker production is a vital link in the loudspeaker manufacturing process, and aims to ensure the stability and the air tightness of a loudspeaker assembly. This process includes precisely controlling the amount of glue applied, the position of application, and the drying time of the glue, ensuring that the glue adheres uniformly and firmly to the desired location. However, this procedure becomes particularly complicated when the flare is provided with a hollowed-out portion. The hollow design can promote sound effect, but also increases the risk that the rubber coating overflows. Due to the specificity of the hollowed-out parts, glue easily flows to the back along the horn mouth during gluing, and redundant glue layers are formed. This not only affects the aesthetic appearance of the product, but also may cause glue to penetrate into the horn, resulting in reduced performance. More seriously, the glue overflow on the back is difficult to remove in the subsequent process, the defective rate is increased, and the production cost is increased. Worse still, consumers may negatively impact brands after purchasing such products, affecting sales and praise of the products.
