Method for intelligently generating coordinates of bending teaching points of sheet metal bending robot

Abstract

The invention discloses a method for intelligently generating coordinates of bending teaching points of a sheet metal bending robot. The method includes the steps that first a virtual sheet metal bending machining environment which is the same as an actual machining environment is constructed by using parametric design and the automatic assembly technology; secondly, through the sheet metal part bending process planning technology, automatic acquisition of sheet metal part bending process information and automatic planning of a corresponding bending process are realized; then through the automatic tool assembly technology, automatic planning and tool assembly of a machine tool lower die bending tool are realized in the bending machining process; and finally, through the intelligent bendingmovement teaching point coordinate generation technology, intelligent generation of the bending teaching point coordinates of the sheet metal bending robot is realized. According to the method for intelligently generating the coordinates of the bending teaching points of the sheet metal bending robot, manual intervention in the sheet metal bending process is fundamentally reduced, the shortcomings of obtaining the bending teaching points by traditional manual online teaching are overcome, the design cycle of sheet metal bending machining is shortened, repetitive labor is avoided, and the product quality is guaranteed.

Description

technical field [0001] The invention relates to the field of off-line programming of sheet metal bending processing, in particular to a technology for intelligently generating coordinates of bending teaching points of a sheet metal bending robot. By optimizing the design of the technical method and verifying its feasibility and practicability, it can meet the production requirements of actual processing, and realize a production method of intelligently generating the coordinates of the automated bending teaching points in the sheet metal bending process. Background technique [0002] The realization of the sheet metal bending process mainly relies on the bending robot to identify the coordinates of the bending teaching points, and carry out the optimal path planning through the coordinates of the bending teaching points, and finally realize the bending operation of the sheet metal parts. [0003] At present, most small and medium-sized sheet metal processing enterprises in C...

Problems solved by technology

[0005] 1. The operation mode of online teaching is not convenient, and the labor productivity of workers is low;

[0006] 2. The auxiliary time (manual teaching, process planning, and knife design) is long, which cannot meet the needs of automated production methods;

[0007] 3. When changing the job task, the bending processing site needs to stop the whole line for teaching, which wastes the processing time of the machine and reduces the production efficiency of the enterprise;

[0008] 4. On-site online teaching operation in the workshop environment is not conducive to the safety of the staff
