Method for controlling product quality according to standards

Abstract

A method for controlling product quality according to standards is used for performing strict standard control when a design department of an enterprise provides production drawings for use of front-line workers and performing strict production drawing aging management when a production department carries out production, and a quality testing department carries out detailed comparison and verification of products, the production drawings and standard contents. According to the method for controlling the product quality according to the standards, components and parts serve as a unit for standard data management; when the standards are altered, designers can timely adjust and alter the production drawings, and production people can carry out management on the data accuracy of the production drawings in the producing process so that correspondence between the production drawings of a production front line and the standards can be ensured; when performing quality testing on the products, quality control personnel can accurately acquire the standards corresponding to the tested products and can perform quality testing on the products according to the latest standards; therefore, implementing of the standards can be ensured, and the product quality is guaranteed.

Description

technical field [0001] The invention relates to a method for managing product quality by checking production drawing data in the process of product production and quality inspection, in particular, a method for managing product quality by using standard data that product components need to follow. Background technique [0002] In the "Standardization Law of the People's Republic of China", it is stipulated that standards should be formulated for the following aspects related to industrial products, [0003] 1. The variety, specification, quality, grade or safety and sanitation requirements of industrial products. [0004] 2. The design, production, inspection, packaging, storage, transportation and use methods of industrial products or the safety and hygiene requirements in the process of production, storage and transportation. [0005] 3. Technical terms, symbols, codes and drawing methods related to industrial production, engineering construction and environmental protect...

Problems solved by technology

[0010] 3. Are the enterprise standards being used still citing the abolished standards? Will the product design still mistakenly adopt the abolished standards and the standards that need to be revised?

[0012] If these problems are not resolved, it will inevitably lead to a reduction in the qualified rate of the product, a waste of materials and processing resources, and in severe cases, it will also bring safety hazards to consumers of the product.

[0013] For example, for an enterprise that produces aircraft engines, each of its aircraft engine products consists of thousands of components, and each component should comply with the corresponding national or military standards or aviation or enterprise standards. , the enterprise standard may refer to the national standard or navigation mark of the upper level. For example, if a bolt should comply with the corresponding enterprise standard, when the content of the national standard quoted by the enterprise standard has been partially changed, the material or processing technology of the bolt should When the change is made, if the enterprise standard cannot be updated in time, or the updated enterprise standard cannot be fed back to the first-line production department through the design department to update the production drawings in time, the production department will still carry out bolt production according to the enterprise standard before the change on the old drawings , In this case, the produced bolts cannot meet the acceptance requirements, thereby wasting materials and processing resources. If these bolts are accidentally assembled on the aircraft engine and circulated to customers, it may also bring serious safety hazards

[0014] The existing standardization management work mainly relies on manpower and paper-based management. Since a single product may involve thousands of standards, on the one hand, pure manual management is inefficient and cannot effectively solve the above problems. It is easy to find out which parts and components a certain standard is used in. In addition, it is easy to cause errors and omissions in standard management information, and it is easy to use (or quote) outdated obsolete standards in enterprise design and production. Outdated standards for design and production, resulting in an increase in the rate of unqualified products, or making the company's products unable to meet customer requirements

[0015] Chinese patent CN101436200A provides a standardized information management system and its standard update method. This patent provides a method that can automatically update the data information of the standard adopted by the enterprise and send the updated information to the corresponding user. However, for the standard in the design , production and other processes have been implemented and did not provide a corresponding solution
