Abstract

The invention provides a probe-type film thickness measuring machine automatic wiped film measuring device and a using method thereof. A wiped film blade, a wiped film debris processing mechanism and a visual field CCD are added to the existing probe-type film thickness measuring machine. The wiped film blade, the wiped film debris processing mechanism and the visual field CCD are all arranged on a measuring disc. Through searching the CCD, a measuring point position of a measuring object is determined. A measuring probe head moves to the measuring point position, a height change curve in a measuring area is drawn, whether the measuring object needs wiped film processing is judged, wiped film coordinates are determined through the relative distance between the wiped film blade and the measuring probe, the point position, the wiped film direction and the wiped film length are selected, the wiped film blade drops, automatic film wiping replaces manual film wiping, the measuring time is greatly reduced, the wiped film measuring precision and the operability are greatly enhanced, and the danger of damaging the measuring object by the wiped film blade can be avoided. The device and the method of the invention are applicable to each channel process for a color substrate.

Description

technical field [0001] The invention relates to a probe-type film thickness measuring machine, in particular to an automatic scraping film measuring device for the probe-type film thickness measuring machine used in the color substrate manufacturing process. Background technique [0002] The current LCD panel industry has ushered in an unprecedented stage of overall development and growth, and market demand is developing towards diversification, which requires improvements in the production of the LCD panel industry. The main process flow of the existing color substrates in the LCD panel industry is coating Cloth→exposure→development, the probe-type film thickness measuring machine is used to measure the film thickness and flatness after each process. Therefore, to reduce the film thickness of the color substrate and improve the flatness of the color substrate, the improved probe Type film thickness measuring machine is particularly important; [0003] The measurement princ...
