Patent automatic thickness measurement and coating control system

The light spot shown in the figure is to detect the coating amount. It can detect CH and oh keys, i.e. oil-based adhesive and water-based adhesive. It can be fed back to the automatic adjustment mechanism within 25ms. The overall correction error can be controlled at ± one point five µ Especially when the high-speed and low-speed production changes and the glue concentration changes with time, with the gap adjustment system designed by our company, the measured value can be displayed on the screen, compared with the set value, and the coating amount can be automatically controlled by feedback effect. It can effectively control coating flatness, save product cost and stabilize product quality
