Composition analysis device and composition analysis method

Abstract

Provided are a composition analysis device and a composition analysis method whereby composition analysis of a by-product gas generated in an ironmaking process can be performed easily, composition analysis and heat calculation can be performed continuously, and the heat of the by-product gas can be measured with higher reliability. A composition analysis device (10) for analyzing the compositionof a gas to be analyzed is provided with: a first measurement means (11) for measuring the concentrations of a plurality of gases to be measured contained in the gas to be analyzed; a conversion heatamount calculation means (13) that includes a second measurement means (12) for measuring the refractive index of the gas to be analyzed and the sound velocity propagating through the gas to be analyzed, and that calculates the conversion heat amount of the gas to be analyzed for each of the refractive index and the sound velocity; a reference miscellaneous gas total error heat amount calculationmeans (14) that calculates, on the basis of the converted heat amount of the gas to be analyzed, an error heat amount that is a reference among error heat amounts generated by miscellaneous gas contained in the gas to be analyzed; and a first non-measured gas concentration calculation means (15) for calculating the concentration of the first gas on the basis of the respective concentrations of themeasured gases and the amount of error heat that is the reference.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a surface defect detection system and method. Background technique [0002] In the prior art, in the assembly process of the mobile phone screen, it is inevitable that there will be adhesives and other transparent or translucent substances such as UV-cured acrylic resin that cannot be cleaned and remain on the mobile phone screen or the mobile phone casing, resulting in product quality problem. As the design requirements of the current mobile phone frame become narrower and narrower, the accuracy and stability of the dispensing amount is difficult to control. If the dispensing amount is too large during the production process, it is very easy to have glue overflow during the assembly process of the mobile phone screen, thus This causes residual glue on the screen or shell of the mobile phone. Therefore, it is necessary to effectively detect the defect of residual glue on the s...

Problems solved by technology

Since most of the glue is transparent and colorless, it is difficult to distinguish the glue from the background on the image. It is necessary to use complex image processing algorithms to segment the image, which not only takes a lot of computing time, but the effect is not necessarily good. Detection has become a major problem in the industry
