Are there ways to prevent mistakes during dispensing? If an operator must apply six dots of adhesive onto a part, are there ways to make sure he did that? Obviously, automating the dispensing process will help, but in lieu of that, assemblers have some other options to achieve an error-proof process.
There are two ways to minimize mistakes during dispensing: prevent mistakes from happening and detect mistakes when they do occur. One of the best ways to detect mistakes is with machine vision. Often, a fluorescent material can be added to the adhesive to facilitate inspection by vision systems.
