Description
Technical field
The present invention relates to a kind of product quality detection system and method, be specifically related to a kind of comprehensive detection evaluation system and method thereof of casting the tin-lead solder product quality, belong to product quality detection technique field.
Background technology
In the quality testing field of product, the chemical constitution of product is one of most important detection index, and a product often has the number of chemical composition.On the other hand, the chemical constitution of product only is the factor that product quality is passed judgment on.For certain series products, quality assessment often will run into many factors, has generally all formulated corresponding standard.By the GB regulation, the tin-lead solder product contains A, B, C Three Estate usually.The index that influences the tin-lead solder product quality has three classes, comprises chemical constitution, outward appearance, weight.The outer appearnce index comprises cleaning, burn into slag inclusion, burr and foreign impurity, and this index does not need accurate measurement.
For metal product, what whether conventional evaluation method met that the quality grade (namely whether qualified) of its nominal adopts to certain product quality is { 0,1} model.Be qualified as certain composition C 〉=C0, then C＜C0 is defective.Yet, be present in the product quality in the reality in a large number and be not suitable for judging with the method for simple " either-or " that the tin-lead solder quality namely is a typical representative.By classical set theory, though may exist most of impurity content in the scope of A level, then not in A level scope, this has all increased the difficulty of quality judging to factors such as certain several impurity element or outward appearance, weight.Therefore, to have ambiguity very realistic for each quality index of tin-lead solder.For the quality of tin-lead solder, owing to each waits inter-stage, there is not clear and definite border, to another grade, the centre has experienced a continuous process from quantitative change to qualitative change by a certain grade.So, can not describe with the fundamental function of only getting 0 or 1 two value in the classical set theory for this set of quality.For describing this continuous transition process in the similar problem, need a kind of a kind of method for comprehensive detection that can embody the product transition state to judge the product quality grade, make it more meet objective reality.

Embodiment
Below by a concrete detection case comprehensive detection evaluation method of the present invention is described:
For step 1, according to the regulation of GB/T8012-2000, the tin-lead solder product can be divided into 3 quality grades usually by its chemical constitution, but simultaneously, also regulation has been made in aspects such as its outward appearance, weight in the standard.N=3, that is: chemical constitution, outward appearance, weight are divided three classes its influencing factors of quality collection U for this reason.Wherein chemical constitution is the quality grade critical value (that is: V) that can accurately measure and provide clear and definite in GB, the outward appearance aspect then can't accurately measure and GB in the quality grade critical value is not provided, can be consulted jointly to determine and provide a concrete quantized value that the weight aspect then provides acceptability limit by both sides of supply and demand.According to the comprehensive detection evaluation system of setting up, respectively three class indexs such as chemical constitution, outward appearance, weight are carried out the one-level multifactorial evaluation then, draw and pass judgment on function B
1, B
2, B
3Carry out the secondary multifactorial evaluation again, draw final judge function C.
Tabulate down 1 is the quality inspection result of first, second, third, fourth, penta, oneself six tin-lead solder ZHLSn60Pb of tin-lead solder producer.Wherein the assay of outward appearance is qualification rate percentage, is consulted to determine by both sides of supply and demand.
Table 1
The one-level multifactorial evaluation:
The multifactorial evaluation of chemical constitution:
With reference to the tin-lead solder ZHLSn60Pb trade mark and chemical composition limit thereof in the GB, correspondingly chemical constitution can be divided into three quality grades (that is: A, B, C).For the identification of its quality grade, the subordinate function of each constituent content can come the quality grade of concentrated expression lead pig from different degree.
At first, according to the characteristic of tin-lead solder chemical constitution, setting up the subordinate function of each chemical constitution, is example with the Bi element, and the subordinate function of its Three Estate is piecewise function as shown in Figure 3.All following tabulations 2 of concrete function expression of element.
Table 2
This function be with in the GB to the regulation of each constituent content as its quality grade critical value, determine the judge function in its corresponding mass grade.Should be not more than 0.01, be not more than 0.05 in the B level product, be not more than 0.1 in the C level product as GB regulation Bi element content in A level product in the table 2, with Bi constituent content in the product as independent variable x, 0.01,0.05,0.1 as the quality grade critical value, determine that its membership function corresponding in three kinds of grades is this function.
