Comprehensive detection and judgment system and method for quality of cast tin-lead solder product

Abstract

The invention discloses a comprehensive detection and judgment system and method for quality of a cast tin-lead solder product. The system comprises an authority identification module, a detection data input module, a membership grade module, a quality grade identifying module, a quality grade judging matrix module, a product quality first-grade judging module and a quality grade output module. The method comprises the following steps of: detecting chemical components, weight and appearance of the tin-lead solder product, establishing membership functions of various grades of the cast tin-lead solder product, calculating the membership degree to obtain a judging matrix, and subsequently carrying out primary judgment and secondary judgment in sequence. The system and the method are simple and reliable, and have the characteristics that the identification is accurate and the judgment efficiency is high; and the defect that comprehensive judgment cannot be realized in the prior art is overcome.

Description

technical field [0001] The invention relates to a product quality detection system and method, in particular to a comprehensive detection and evaluation system and method for casting tin-lead solder product quality, belonging to the technical field of product quality detection. Background technique [0002] In the field of product quality inspection, the chemical composition of the product is one of the most important detection indicators, and a product often has multiple chemical compositions. On the other hand, the chemical composition of a product is only one factor in judging product quality. For a certain type of product, many factors are often encountered in quality evaluation, and corresponding standards are generally formulated. According to the national standard, tin-lead solder products usually contain three grades of A, B, and C. There are three types of indicators that affect the quality of tin-lead solder products, including chemical composition, appearance, a...

However, the quality of a large number of products in reality is not suitable for judging by a simple "either-or" method. The quality of tin-lead solder is a typical representative

According to classical set theory, although the content of most impurity elements may be within the scope of grade A, some impurity elements or appearance, weight and other factors are not within the scope of grade A, which increases the difficulty of quality judgment
