Problems solved by technology

[0002] Due to the characteristics of the glass processing and manufacturing process, the processed glass may have defects such as foreign matter or bubbles in the glass. In order to select high-quality glass without such defects for use or reprocessing, people have long been concerned about the defects in the glass. Bubbles, foreign matter, etc. are detected by being irradiated by a surface light source, and the method of frontal visual inspection is used. This detection method has low reliability, especially for the inspection of nickel sulfide in the glass. The reliability is even lower, because there is no good method , resulting in the need for heat treatment to facilitate cracking of the ex-factory glass

Embodiment Construction

[0009] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0010] The first step is to lay the glass to be inspected (1) horizontally, and after placing it stably, set the laser light source (2) on the right side of the glass to be inspected (1), and set the computer linear scanning head (3) on the glass to be inspected (1) above.

[0011] The second step is to turn on the laser light source (2), the laser line (4) is transmitted into the glass (1) to be inspected from the right side of the glass (1) to be inspected at a positive transmission angle, and the computer linear scanning head (3) scans the transmission Enter the laser line (4) in the glass (1) to be inspected, and at the same time, transmit the scanning result to the computer for processing, and judge whether the transmitted laser line (4) is blocked or change the transmission direction, etc...

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 [0001] The invention relates to a detection method in the field of glass manufacturing and processing industries, in particular to a detection method for glass foreign matter bubbles. Background technique [0002] Due to the characteristics of the glass processing and manufacturing process, the processed glass may have defects such as foreign matter or bubbles in the glass. In order to select high-quality glass without such defects for use or reprocessing, people have long been concerned about the defects in the glass. Bubbles, foreign matter, etc. are detected by being irradiated by a surface light source, and the method of frontal visual inspection is used. This detection method has low reliability, especially for the inspection of nickel sulfide in the glass. The reliability is even lower, because there is no good method , leading to the need for heat treatment to promote cracking of the glass that leaves the factory. Contents of the invention [0003] ...
