Embodiment Construction

[0019] 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 assembly line. The robot station design method applied to the welding assembly line comprises the following steps that a welding point distribution range pattern and a reachable working space pattern of a robot are determined; the welding point distribution range pattern and the reachable working space pattern are used forobtaining a station range pattern to be selected; a pattern equal segmentation method is used for performing step-by-step block segmentation on the station range pattern to be selected to obtain a station point set to be selected; according to a robot kinematics model and a robot inverse kinematics method, the distance sum of each welding point of a station point to be selected and the sum of theoperability values of the welding points are solved; and a maximum value of the evaluation function based on an operability index and a distance index is used as an optimization target, the optimal station point of the robot is found through loop iteration, and the station design of the welding assembly line robot is achieved. The robot station design method applied to the welding assembly line has reasonable conception and novel conception, reasonable design of the welding assembly line robot station is achieved, the welding utilization rate of the welding robot can be improved, the flexibleand efficient production of the welding assembly line is achieved, and the practicability is relatively high.

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 ...
