Free typesetting cutting method of stone cutting robot

Abstract

The invention discloses a free typesetting cutting method of a stone cutting robot. The method comprises the following steps of 1 collecting and correcting images, 2 selecting typesetting regions andan initial point, 3 reading an order, 4 selecting a typesetting mode, 5 setting a bad block, 6 optimizing a typesetting scheme, 7 finishing typesetting, 8 labelling a flagstone, 9 performing automaticcutting and 10 performing information statistics. Manual measurement of the size of the flagstone is replaced with image collection and correction, flagstone contour extraction and optical measurement. A free or automatic typesetting algorithm is used for replacing artificial typesetting, the typesetting efficiency is improved, and the stone utilizing rate is increased. Manual paper-and-pencil recording is replaced with automatic recording of the whole process of automatic order loading and analyzing, typesetting and cutting, and the order completion status, historical typesetting recording,the cut flagstone number, area and total utilizing rate and the like can be checked in real time, and the production process is traceable. Cut sample plate labeling can be automatically completed, andstorage, operation and maintenance management can be convenient.

Description

technical field [0001] The invention relates to stone cutting, in particular to a stone cutting robot free layout cutting method. Background technique [0002] At present, the traditional stone slab cutting method adopts manual typesetting. Before cutting stone with a stone cutting machine, it is necessary to manually measure the size of the stone, and then according to the actual processing requirements, manually formulate a typesetting plan and a cutting plan to meet the different needs of shape and size. Ensure the high utilization rate of the whole stone. In this process, it is time-consuming and labor-intensive, and the accuracy is low, and human errors are prone to occur, so that the typesetting and cutting schemes are often not optimal. [0003] Application number: CN201610591893.0 Chinese invention patent discloses an intelligent stone cutting method based on machine vision, which can improve accuracy and reduce errors to a certain extent, but it has the following t...

AI Technical Summary

Problems solved by technology

[0004] (1) Image correction uses a large-format checkerboard calibration board. It is difficult to ensure high precision in the production of large-scale calibration boards, the production cost is high, and the installation is difficult;

[0005] (2) In an environment with insufficient light, or when the stone slab is very close to the base, it is difficult to accurately extract the contour of the slate. Using contour correction is time-consuming and laborious, and the accuracy of contour extraction cannot be fully guaranteed;

[0006] (3) Some processing orders at the processing site are relatively special, or the shape of the slate is relatively special, and the automatic typesetting algorithm cannot meet the typesetting requirements;

[0007] (4) In case of special circumstances such as power failure or crash, there will be no breakpoint resume function after restarting the machine;

[0008] (5) There is no label for the cutting model, which is not conducive to the later storage and operation and maintenance management
