Robot assembly operation demonstration programming method and device based on reverse engineering

Abstract

The invention discloses a robot assembly operation demonstration programming method and device based on reverse engineering. The method comprises the steps that point cloud acquisition is carried outon each workpiece of an assembly body by using a three-dimensional scanner in a workpiece model reconstruction system, a point cloud filtering algorithm is used for processing collected point cloud, and professional reverse engineering software is used for completing reconstruction of a workpiece model on the basis of processed point cloud data. The device comprises the three-dimensional scanner,a binocular camera and the like. When the production process or the assembly workpiece needs to be adjusted, only the assembly operation needs to be demonstrated again, and a robot does not need to beprogrammed again, so that the production efficiency of products is greatly improved. The technology is especially suitable for the flexible manufacturing industry with the characteristics of multiplevarieties, small batches and a short period.

Description

technical field [0001] The invention relates to reverse engineering technology and industrial robot demonstration programming technology, in particular to a reverse engineering-based robot assembly operation demonstration programming method and device. Background technique [0002] Reverse engineering technology refers to the comprehensive measurement of the real object or model by means of certain measurement methods, and the reconstruction of the model based on the data obtained after measurement. Reverse engineering technology includes a wide range of technical directions, such as shape reverse, material reverse, process reverse, etc., and it is mainly applied in the following aspects in the industrial field: remodeling or profiling design of new products; Some products are copied to clarify the design intent of the original product; the worn parts are restored; the model is digitally inspected to facilitate comparative analysis between models, such as analyzing the cause...

Problems solved by technology

Traditional industrial robots can only complete the tasks of specified actions. Although they have the advantages of high precision and fast execution, they lack flexibility.

And when it is necessary to change the operation object and operation action, the robot needs to be reprogrammed, and sometimes even the entire production line needs to be updated

Therefore, with the characteristics of short production time, high update frequency, and short life cycle of industrial products, the traditional robot programming method cannot meet the new needs, and a more flexible programming method is needed to improve programming efficiency and shorten robot life. reprogramming time
