Method for visually evaluating quality of electrotinning solution on line

Abstract

The invention discloses a method for visually evaluating the quality of an electrotinning solution on line. The method comprises the following steps: sampling on line: obtaining the electrotinning solution from an electrotinning unit operation tank in real time and putting the electrotinning solution into a transparent container; data collection: moving the transparent container containing the electroplating solution to a camera shooting detection area, and collecting online solution color parameters of pixel points in the detection area; evaluating and grading: comparing the color parametersof the online solution with the color parameters of the graded solution, and determining the grade corresponding to the color parameter of the graded solution, which is optimally matched with the color parameters of the online solution, so as to determine the quality grade of the solution; and result feedback: taking corresponding measures on the electrotinning unit according to the solution quality grade. By means of the method, whether the quality of the electroplating solution meets the product production requirement or not can be evaluated online in time, the hysteresis quality of offlinedetection is avoided, potential quality hazards generated by the quality of the electroplating solution are reduced, quality early warning is conducted in time, advanced intervention of product quality management is promoted, and finally quality preventive management and control are achieved.

Description

technical field [0001] The invention belongs to the technical field of product quality detection, and in particular relates to a method for visually and online evaluating the quality of an electroplating tin solution. Background technique [0002] Electroplated tin products are widely used in high-end manufacturing industries such as food, automobiles, and home appliances due to their light weight, aesthetics, good corrosion resistance, and direct processing. Since the tinning unit is a chemical unit, the quality of the solution will directly determine the surface quality of the electroplating layer. In order to ensure the quality of electroplated tin products, it is particularly important to detect and control the components of the electroplating solution during the production process. [0003] In the prior art, the composition detection of the electroplating solution is mainly divided into on-line detection and off-line detection. At present, the detection of process par...

However, substances without characteristic spectral lines cannot be detected, and the detection is greatly limited

There are many types of electrochemical detection, and the detection accuracy is high. However, since the detection objects in the iron and steel industry belong to the harsh environment such as high temperature, strong acid or strong alkali, and dirty solution, it is extremely difficult to manufacture an online detection system, and the device manufacturing is relatively complicated and the cost is high.
