Welding scheme generation method, welding scheme generation device and welding system

Abstract

The embodiment of the invention provides a welding scheme generation method, a welding scheme generation device and a welding system. The welding scheme generation method comprises the following steps: obtaining a triangular patch model of a to-be-processed member and generating an initial welding scheme according to the triangular patch model; measuring the coordinate of a welding point in the to-be-processed member secondarily and correcting the triangular patch model according to a secondary measuring result; and correcting the initial welding scheme according to the corrected triangular patch model to obtain a final welding scheme. The welding scheme generation method, the welding scheme generation device and the welding system are particularly suitable for processing members of steelplate structures, similar to small assemblies, in shipbuilding industry. The members are relatively simple in structure, so that the demand on artificial participation by equipment can be further reduced, the processing time is saved, and the processing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent processing, and more specifically, to a welding scheme generation method, device and welding system. Background technique [0002] For the manufacturing needs of small batches and multi-variety parts, such as the welding of small stand-alone parts in the shipbuilding industry, industrial robots have not been well applied. The reason for such defects is that the working procedures of traditional industrial robots generally pass Online teaching with manual participation or offline programming of existing workpiece models. [0003] The first solution relies on the operator's vision and manual jogging to complete the whole process. The whole process is not only time-consuming and laborious, but also the accuracy cannot be effectively guaranteed because the distance between the end processing part and the component is determined by the operator's naked eyes. And for a slightly complicated machinin...

Problems solved by technology

However, the method proposed by this technology does not have the function of correcting the errors of the generated model and the actual environment, so it is limited in applications with high precision requirements.

In addition, some other automatic programming methods of the same type are also limited by such problems, and are only used in processing occasions with low precision requirements such as spraying and handling
