Description

Technical Field

[0001] This utility model relates to the field of circuit board dispensing technology, and in particular to a dispensing device for circuit board production. Background Technology

[0002] On the one hand, existing dispensing devices mostly use integrated fixed structures or snap-fit ​​connections for their dispensing heads, which have fixed and non-adjustable diameters. When facing the production needs of circuit boards of different sizes, if it is necessary to adjust the dispensing volume or dispensing accuracy (e.g., small circuit boards require small-diameter dispensing heads to control the amount of glue and avoid overflow, while large circuit boards require large-diameter dispensing heads to improve dispensing efficiency), operators need to replace the entire dispensing head assembly. This not only requires the stocking of dispensing head accessories of various specifications, increasing equipment costs, but also causes process interruptions due to the cumbersome component replacement process, significantly reducing production continuity. The versatility of the device is insufficient to meet diverse production needs.

[0003] On the other hand, after dispensing, existing dispensing equipment relies primarily on natural cooling to cure the adhesive and bond components to the circuit board. Natural cooling is highly susceptible to ambient temperature and humidity, and the curing cycle typically lasts several minutes or even longer. During this period, subsequent assembly and testing processes cannot be performed, severely limiting the overall production efficiency of the circuit board. Furthermore, if the adhesive is not fully cured before proceeding to the next process, quality issues such as component displacement and adhesive cracking can easily occur, leading to a decrease in product qualification rates. The equipment's ability to operate in high-efficiency processing scenarios is significantly limited, making it difficult to adapt to the rapid operation requirements of modern production lines.
