Design of Rear Floor of Automobile Flexible Automatic Welding Production Line

With the increasing production capacity of DongFeng Honda second factory, the cost of labor, workers labor intensity, quality, and process stability faces enormous challenges. DongFeng Honda no. 2 welding department promotes to sustain economic restructuring automation project step by step to achieve goals to reduce manual labor costs and improve the quality of body. The no. 2 welding department promotes to carry out the manual line renovation project of rear frame and rear panel to flexible automatic production line. Through the optimization of design by installing 10 welding robots, 3 handle robots, 1 gluing robot, and 1 stud welding equipment to realize 6 models of vehicle production in the same flexible line. Through the automation renovation project, we can realize cutting 22 workers and welding points automation rate increase 4.25%,and it cut down labor cost 2.48424 million RMB per year. It is not only achieved to reduce manual labor cost and improve the quality of the body, and the purpose of ensuring process stability, but also the automation can provide strong quality guarantee and cost reduction for the follow-up new model introduction.
