    Abstract: An auxiliary operation device for a droplet dispenser includes a droplet sensor, an imaging device and a processor. The droplet sensor has a detected area located between a droplet dispenser and a target area, wherein the droplet sensor detects a droplet output from the droplet dispenser, and outputs a corresponding droplet detection signal. The imaging device captures an image of the target area. The processor obtains a dripping time point at which the droplet passes through the detected area according to the droplet detection signal, and determines whether the target area is shielded within a first time range according to the image, so as to evaluate whether the droplet has successfully dropped into the target area. The above-mentioned auxiliary operating device of the droplet dispenser can objectively determine whether the droplets successfully drops into the target area, and improve the accuracy of judgment.
