Embodiment Construction

[0021] The invention provides a robot station design method applied to a welding line, which solves the problems of long time-consuming welding movement posture and high energy consumption existing in the placement of traditional robot stations. It should be emphasized that the robot station design method applied to welding lines proposed by the present invention is not only applicable to automobile welding lines, but also applicable to welding lines of other products. The basic content of the design method of the present invention is: at first, determine the reachable work space figure of welding point distribution range figure and robot; The set of station points to be selected is obtained by segmenting blocks step by step; finally, the optimal station point selection is realized by using the evaluation function based on the operability index and the distance index, and the station design of the welding robot is completed. The technical solutions of the present invention wil...

Abstract

The invention relates to a robot station design method applied to a welding line, comprising the following steps: determining the distribution range graph of solder joints and the accessible workspace graph of the robot; using the distribution range graph of solder joints and the accessible workspace graph to obtain the Select the range graph of the station; use the graph equal segmentation method to segment the graph of the range of the station to be selected step by step to obtain the point set of the station to be selected; solve the points of the station to be selected according to the robot kinematics model and the robot inverse kinematics method The sum of the distances of each solder joint and the sum of operability values ​​of all solder joints; taking the maximum value of the evaluation function based on the operability index and distance index as the optimization goal, find the optimal station point of the robot through cyclic iterations, and realize the welding The station design of the assembly robot. The present invention has a reasonable concept and a novel idea, so that the robot stations of the welding assembly line can be reasonably designed, the welding utilization rate of the welding robot can be improved, the flexible and efficient production of the welding assembly line can be realized, and the utility model has strong practicability.

Description

technical field [0001] The invention relates to the technical field of robot station design in a welding production line, in particular to a robot station design method applied to a welding line. Background technique [0002] With the improvement of people's living standards and the development of the automobile industry, the market demand for automobiles continues to increase. Efficient production efficiency is an important manifestation of production capacity, and it is also an important competitive weapon for companies to seize market share. Nowadays, robot technology is mature and widely used. Robots have become the mainstream "workers" of automobile production lines. Various car companies use robots to complete welding, spraying, assembly and other tasks, so that the entire production line can achieve efficient and safe automated production. [0003] Among them, for the welding production line, the number of solder joints on the car body is huge and the distribution is ...
