| Under the background of Industry 4.0 and Made in China 2025,the level of industrial intelligence in China has been improving,and robots are gradually recognized and widely used to replace manual work in difficult,dangerous and heavy repetitive labor positions.In the steel industry,the sintering process is an important part of the blast furnace iron-making system,which is characterized by a long operating process,a wide variety of raw materials required and a poor operating environment.In the sintering batching position,for example,all production operations are heavy and repetitive labor,and it is urgent to introduce robots for repetitive labor to achieve the purpose of reducing staff and increasing efficiency.The output and quality level of sinter ore are directly related to the particle size distribution of the raw materials used.However,the traditional inspection mode,which are manually sampled and sent for inspection,have obvious data lag,and the continuity and accuracy are difficult to guarantee,which cannot play a good role in production guidance.In this paper,from the perspective of promoting the industrial upgrading of iron and steel industry,the inspection robot with particle size composition analysis of raw fuel for sintering as the main function is designed and developed,which has strong practical significance in promoting the digital intelligence upgrading of traditional iron and steel industry.This paper aims at the product innovation design of sintered batching material inspection robot,and applies Theory of the Solution of Inventive Problems(TRIZ)to guide the design.In turn,four aspects are developed: theoretical research,requirement analysis,formation and improvement of functional solutions,and in-depth practice of the design.First,according to the different approaches to problem analysis and solution in TRIZ theory system,the main methods applied in different innovation design stages are determined to form the functional solution design process.The design methods based on generalized scientific effects are used in the solution formation stage,and in the solution refinement stage,the functional model is mainly used to analyze the component functions,obtain the interactions between components,and use TRIZ theory solution tools to solve the harmful functions and correct the insufficient functions to form the innovative product solution.Second,the thesis obtains product requirements through data analysis,field research,user behavior observation and expert interviews,analyzes user requirements using the Kano model,and determines the attribution category and identify the key requirements.Then,the functional needs and technical requirements of the sintered batching material inspection robot are analyzed based on the functional solution design process to determine the solution of its functional elements,and the preliminary functional solution is determined based on the morphological matrix.Three sets of contradictions between material dust and pressure sensor,sintered material and screen,and shell and track are obtained through functional model analysis,corresponding to technical contradiction,material-field analysis,and physical contradiction respectively,and the principle of invention is used to solve the contradiction and conflict and improve the functional solution.Finally,product design elements such as product structure layout,product shape,color and size are analyzed on the basis of meeting functional requirements,product structure layout and product design style features are determined,product component design is discussed,product solutions are formed,and product appearance models are constructed.This paper uses TRIZ theory to realize the improvement of the innovative product design process,obtains the functional solution by analyzing the product functional structure,focuses on the problem of particle size analysis,realizes the automation requirement of sintering batching material inspection,and provides a reference and an approach for the functional solution of the innovative product. |
