Design And Analysis Of Mechanical System For Automatic Welding Production Line Of Solar Panel Busbar

Welding of solar panel busbar is an important part of solar panel assembly technology,and its welding quality directly affects the resistance value and service life of the solar panel.Because the welding of bus bar is a further process based on battery string welding,which has a high operating difficulty,and the unfinished Package of battery chip is fragile,the welding is of great risk.Therefore,most bus bar welding operations are completed manually or by partially automatic equipment.With the shortage of fossil energy and people’s attention attached to the photovoltaic power,it is difficult for the existing welding methods to meet the diversified market demand.In order to improve the efficiency and quality of the solar panel busbar welding process and reduce the welding cost,the project is aims at the design and analysis of the automatic welding production line of the solar panel busbar.Firstly,this paper summarizes the principles of solar panel modules and the traditional welding process of solar panel busbar,analyzes the defects of existing mainstream equipment,and concludes that the design difficulties of this production line lie in the positioning problem of busbar and battery string in the transmission process together with the problem of high quality and high efficiency welding at the site to be welded.Then,according to the difficult points discussed,the main design points of this production line were divided and corresponding to the design solution of 9 process points,and the equipment process was reformulated and the module was divided accordingly.Based on the principle of production balance,the functional modules are integrated into four structures:waiting station,labrador station,swing station and welding station,so as to ensure that the Design of the production line has a high production capacity on the premise of meeting the functional requirements.Based on the principle of lowest transmission cost,a mathematical model is established for the layout of production line,and the optimal layout result is obtained based on genetic algorithm.Based on the overall design above,this paper carries out further design and research on the core functional structure of the production line.Finally,CAXA3D software was used to build a virtual prototype of the production line,and DELMA software was used to carry out motion simulation of the design scheme,so as to verify the rationality of the scheme design from a macro perspective.The mechanical system design scheme of automatic welding production line for solar panel busbar developed in this paper solves the problems of low production capacity,easily damaged Battery chip and low welding accuracy of the existing equipment,fills the gap in the industry,and improves the core competitiveness of the equipment in the market.
