Abstract

The invention discloses a method for planning the optimal welding track of automobile inner trims and exterior parts. Welding point distribution can be analyzed for different welding component objects, and the corresponding welding tracks are obtained through calculation. The method comprises the first step of welding joint information pretreatment, the second step of welding point sequence planning based on the simulated annealing particle swarm optimization, and the third step of converting of the welding point planning information into the welding robot movement track. An automobile inner trim and exterior part welding robot needs to conduct machining on different hook faces, and when the kind of machining task is conducted, welding points of materials needing to be machined have the characteristics that the number is large, the welding point distribution is scattered, welded components are scattered, and various sizes exist. On a welding production line, the same welding task is repeatedly executed, the number of the welding points is large, and consequently the welding task workload is large. The method can effectively provide the path with the minimum moving distance under the situation of multiple welding points of different welding components, and good flexibility and rapidness are achieved.

Description

technical field [0001] The invention relates to the technical field of welding path planning, in particular to a method for an optimal welding trajectory for interior and exterior trim parts of an automobile. Background technique [0002] Welding robots for automotive interior and exterior trims need to be processed on different surfaces. Generally speaking, when performing such processing tasks, the number of solder joints of the material to be processed is large, the distribution of solder joints is relatively scattered, and the welded components are scattered and have many dimensions. In the welding production line, the same welding task is repeated, and the large number of welding points leads to a large workload of the welding task. Therefore, it is necessary to reasonably plan the welding points in the welding tasks of automobile interior and exterior trim parts, which will improve the overall production efficiency and It has a positive effect on improving economic ef...
