Glass surface sweeping method and system

Abstract

The invention discloses a glass surface sweeping method and system. The glass surface sweeping method includes: (a), arranging a glass position detecting device to detect position of glass; (b), sending out a control signal by the glass position detecting device according to the position; (c), arranging a fluid feeding unit to provide fluid for sweeping the surface of the glass; (d), setting a fluid control valve to control the fluid of the fluid feeding unit; (e), according to the control signal, controlling the fluid control valve to control feeding and stopping of the fluid of a compressed air unit so as to control sweeping of the surface of the glass. The glass surface sweeping method has the advantages that by automatically controlling feeding and stopping of compressed air for sweeping, the compressed air is fed into an air collecting pipe and sweeps the surface of the glass through an air blowing nozzle, so that impurities on the surface of coated glass are removed conveniently and effectively, and accuracy of manual detection and automatic detection is improved.

Description

technical field [0001] The invention relates to a coated glass product, and more particularly relates to a method for purging the surface of the coated glass and a purging system for implementing the purging method. Background technique [0002] Generally speaking, for large-scale glass coating production lines, especially production lines such as offline coating, the glass must first enter the manual inspection section after coating to perform manual inspection of the film surface quality. The detection section is generally located in a dark detection room, and detection light boxes are arranged on the upper and lower parts of the roller table in the detection section to observe more intuitively whether there are spots, pinholes, slag, scratches and other defects on the film surface of the coated glass product. Manually predict whether the quality of coated glass is qualified. [0003] Before the coated glass exits the cavity, the discharge chamber needs to be emptied. The...

AI Technical Summary

Problems solved by technology

In this way, when the coated glass enters the manual inspection roller table, it will interfere with the judgment of the inspection personnel, and it will also affect the detection results of the subsequent online automatic inspection instrument, which will have a great impact on the quality inspection of coated glass products.

At present, most coated glass production lines are not equipped with a cleaning system for impurities on the surface of coated glass. Some manufacturers may connect a compressed air pipe for manual cleaning, which increases the work intensity of the inspectors, and the metal blowing pipe may damage the film surface. cause scratches
