Abstract
The invention relates to a method for detecting foreign matters and bobbles in glass. Firstly, after glass to be detected is laid or erected and is stably placed, a light source is arranged at one side of the glass to be detected; then rays of the light source are transmitted into the glass to be detected from a positive transdermal shadow angle at the side of the glass to be detected and are scanned by people through adopting a visual check method or adopting a linear scanning head of a computer; according to factors, i.e. whether the transmitted rays into the glass to be detected are blocked or changed into other transmission directions, the defects of the glass with foreign matters, bobbles, nickel purite, and the like can be detected.
Description
Technical field
The present invention relates to detection method, the especially glass foreign bubble detecting method in glass manufacturing and processing industry field.
Background technology
Because might there be defectives such as foreign matter or bubble are arranged in the glass in the glass that adds after manufacturing technical feature causes shaping of glass, use or reprocess in order to select the glass high-quality glass that does not have this type of defective, for a long time, it all is to take the quilt cover light source irradiation that people detect for the bubble in the glass, foreign matter etc., the method of positive visual examination, this detection method reliability is low, particularly for the inspection of the nickel sulfide of glass the inside, reliability is lower, owing to do not have good method, cause and to promote thermal treatment to the glass explosion of dispatching from the factory.
Summary of the invention
The objective of the invention is provides a kind of glass foreign bubble detecting method in order to overcome above-mentioned shortcoming of the prior art.
The technical solution used in the present invention is: at first glass to be checked is kept flat or places vertically, after stable the placement, light source is arranged on the side of glass to be checked, positive shadow-mark angle is transmitted into glass to be checked to source light from the side of glass to be checked, people adopt the method for visual examination again or adopt the linear scanner head scanning transmission of computing machine to go into source light in the glass to be checked, whether be blocked or change key elements such as transmission direction according to being transmitted to light in the glass to be checked, can detect whether there are defectives such as foreign matter, bubble, nickel sulfide in the glass to be checked.
Via enforcement of the present invention, can reliable detection go out whether deposit nickel sulfide, foreign matter and bubble etc. in the glass to be checked.
Via enforcement of the present invention, the reliability of testing result improves greatly, effectively improves the ex factory pass rate of product.
Description of drawings
Fig. 1 is a detection principle schematic of the present invention
In the drawings, 1 glass to be checked, 2 LASER Light Source, the linear scanner head of 3 computing machines, 4 laser rays, 5 foreign matters, 6 bubbles, 7 nickel sulfides
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is further introduced, but not as qualification of the present invention.
The first step at first keeps flat glass to be checked (1), after stable the placement, LASER Light Source (2) is arranged on the right positive side of glass to be checked (1), and the linear scanner head of computing machine (3) is erected at the top of glass to be checked (1).
Second step, open LASER Light Source (2), laser rays (4) is transmitted in the glass to be checked (1) from the positive shadow-mark angle of the right flank of glass to be checked (1), the laser rays (4) that linear scanner head (3) scanning transmission of computing machine is gone into glass to be checked (1) lining, simultaneously, scanning result is transferred in the computing machine handles, whether be blocked or change key element such as transmission direction according to the laser rays (4) of transmission, judge whether detect glass to be checked (1) lining exists foreign matter (5), bubble (6), nickel sulfide defectives such as (7).
Detection method program of the present invention is simple, and is convenient easy-to-use, and testing result is reliable, be widely used in glass manufacturing and processing industry detects glass and whether have defective fields such as foreign matter, bubble, nickel sulfide.
Claims (1)
1, the present invention relates to glass foreign bubble detecting method, specifically may further comprise the steps:
The first step at first keeps flat glass to be checked or place vertically, after stable the placement, light source is arranged on the positive side of glass to be checked, and people's vision is positioned at the top of glass to be checked or the top that the linear scanner head of computing machine is erected at glass to be checked.
Second step, open light source, positive shadow-mark angle is transmitted into glass to be checked to source light from the side of glass to be checked, people adopt the method for visual examination again or adopt the linear scanner head scanning transmission of computing machine to go into source light in the glass to be checked, whether be blocked or change key elements such as transmission direction according to being transmitted to light in the glass to be checked, can detect whether there are defectives such as foreign matter, bubble, nickel sulfide in the glass.
