1.1. Overview

 

A sealer application is used for the robot controller to directly control the application amount of the sealing process to apply the sealer solution on a workpiece for adhesion, waterproofness, or vibration control. Generally, the sealer application process consists of a pump, filter unit, and a gun booster unit, but this function covers the control of a gun booster unit that has a direct connection with the application amount control.

This function provides initial pressurization control before discharge for initial quality and support for different application methods based on process characteristics through constant quantity and speed discharges as well as robot speed-synchronized discharge control modes.
