Research On The Key Technique Of Automatic Welding For Crystalline Silicon Solar Cells

With the development of society, the human society operation and development of the basicmaterial conditions in nearly one hundred years-energy consumption in there for all to see. Ashort period of traditional non-renewable fossil energy reserves and the limitation of humansocial development between the growing energy demand produced more and more inevitablecontradictions. Therefore, for the purpose of realizing the goals of sustainable development ofthe human society, it is necessary to intensify the renewable energy development and utilization.As the representative of the new energy, Solar energy has many advantages and becomes thefocus of the new energy development object. Solar power technology is the key of the solar cell,and the cell junction with the welding is the focus of the solar cell. the study of the high qualitywelding quality automatic welding equipment is very important to the further development of thephotovoltaic industry in our country. Therefore, the study of the crystalline silicon solar cellwelding key technology is of great theoretical and practical significance.Firstly, based on the understanding of the crystalline silicon solar cell manual weldingtechnology, summarizes the existing automatic welding machine production process, the analysisof the automatic welding machine in the actual production of the problems they faced, anddetermined the automatic welding process and welding way, laid the foundation of research, andpoints out the research direction.Secondly, the article, which analyzes the question of welding mechanism of the weldingsystem and kinematics and statics of the mechanism model, welding mechanism model isestablished. By kinematics analysis, improvement of CAM mechanism to control the weldingmechanism motion accuracy, improve the stability of the movement. Affected by statics analysisof adaptive deflection mechanism welding properties of key parameters, provide theoretical basisfor institutional improvement. USES the results of analysis of the existing welding mechanism ofCAM profile curve and adaptive deflection of structure optimization, reduce the weldingmechanism caused by fragmentation, finally using the effectiveness and stability of theexperiment proves that the optimized mechanism. Thirdly, the article analyzes the reasons of welding heating body temperature distributionproblem in the welding system, and puts forward the feasibility of the alternatives and by use ofANSYS software, the new scheme in the thermodynamic simulation. Then according to thesimulation results of the existing heating body structure optimized, which finally proved thecorrectness of the uniform of the new structure heating body temperature through theexperiments.Finally, the solar cell welding equipment for experimental platform, the experiments show thecorrectness of the welding system design under the guidance of the theory which providestheoretical support for realizing industrialization production.
