A Technical Research of Glass Thickness Detection Based on CCD Displacement Sensor
China has over one hundred of glass production lines, which are about 200 meter. It can produce different kinds of sheet glass. When changing the thickness of class, it will take a long time to regulate the productive method. If the thickness of glass brand is not stable, it will result in great waste. However, if we can detect the glass thickness in the hot side of the tinbath or annealing kiln and provide the data in time, we can shorten the time and reduce the cost. Our research project adopts laser trigonometry displacement measure theory in the hot side of annealing kiln to make sensibility of the reaction signal low and noise loud at the surface of glass. Furthermore, we must use special methods to deal with the signal. Through the experimental validating and the data-analyzing, the theory and the method are feasible.The research in this field has great significance to improve our country’s glass production quality, cut down the production cost and lessen the waste of materials.
