Method for detecting gas line defect of glass tube

Abstract

The invention relates to a method for detecting a gas line defect of a glass tube, and belongs to the technical field of measurement and testing. The method comprises the following operation steps of: a, by three groups of shooting equipment arranged on a glass tube pulling wire, carrying out shooting on the glass tube and acquiring image information according to a set frequency, and transmitting the image information to a processor; b, by the processor, analyzing each image information and judging whether a gas line exists on a glass tube section corresponding to the each image information; c, when a judgment result is that the gas line does not exist on the glass tube, determining the section of the glass tube as a qualified product; d, when the judgment result is that the gas line exists on the glass tube, by the processor, calculating out a length L1 of the gas line, and comparing the length L1 with a preset gas line length standard value L; e, when N1 is greater than or equal to N, determining that the section of the glass tube is an unqualified product; f, when N1 is smaller than N, determining that the section of the glass tube is a qualified product. The method is high in reliability and high in working efficiency, and not only can be coordinated with the beat of a production line, but also ensures body health of an operator.

Description

technical field [0001] The invention relates to a glass tube product detection method, in particular to a glass tube gas line defect detection method, which belongs to the technical field of testing and measurement. Background technique [0002] Bubbles in the glass are visible gaseous inclusions. During the glass tube forming process, the bubbles are elongated into lines called gas lines. Gas lines are a common defect in medium boron glass tubes. In the pharmaceutical glass industry, medium-boron glass tubes are generally used to process glass bottle products. When there are gas line defects in the glass tube, it will not only damage the appearance quality and mechanical strength of the glass bottle products, but may also directly affect the glass bottle products. The quality of the medicine makes the medicine go bad. Therefore, medicinal glass tubes have very strict requirements on gas lines, and gas line defect inspection must be carried out after the glass tubes are hot...

AI Technical Summary

Problems solved by technology

[0003] For the detection of gas line defects in glass tubes, the manual detection method not only has the disadvantages of poor reliability, low work efficiency, and difficulty in coordinating with the production line beat, but also is limited by operating conditions, requiring the operator to hold the glass tube at the light source Careful observation can easily cause eye fatigue of the operator and bring adverse effects on the health of the operator. At the same time, there are pollution of the glass tube and bumps during placement.
