Description

Printing and cutting integrated processing method, device and storage medium Technical Field The application relates to the field of material processing, in particular to a printing and cutting integrated processing method, printing and cutting integrated processing equipment and a storage medium. Background In the field of flexible material processing, particularly in the processing process of clothing cut-pieces, shoe materials, luggage parts, advertisement spray painting cloth and other materials, two procedures of pattern printing and shape cutting are usually required to be completed simultaneously. The traditional processing mode is to separate printing and cutting into two independent links, namely, firstly, pattern printing of batch materials is finished on printing equipment, and then, the printed materials are transferred to cutting equipment for outline cutting. The separated processing mode causes that the materials need to be subjected to twice feeding, twice positioning and middle manual handling and stacking, so that the process is complex, the efficiency is low, and the position deviation is extremely easy to introduce in the material transferring process. When facing the personalized orders of small batches and multiple varieties, the frequent material changing and machine adjusting time even exceeds the actual processing time, and the production efficiency and the flexible response capability are severely restricted. In order to solve the problem, a scheme of integrating printing and cutting into the same machine table appears in the industry, and two working procedures are connected in series through a conveyor belt or the same motion platform, so that printing and cutting can be completed by one-time feeding. However, the integration scheme still faces a core difficulty that the printing process and the cutting process are close to each other in physical position, but the printing process and the cutting process are respectively and independently moved, and lack of uniform coordinate references, so that the actual position of a printed pattern cannot be accurately followed during cutting, and even if the material placement position is slightly shifted or rotated, dislocation of a cutting contour and the printed pattern is caused, so that a large amount of waste products are generated. Therefore, how to realize the real integrated integration of printing and cutting on the flexible material and solve the problem of printing and cutting dislocation caused by nonlinear deformation of the material becomes a technical problem to be solved in the field. The foregoing is provided merely for the purpose of facilitating understanding of the technical solutions of the present application and is not intended to represent an admission that the foregoing is prior art. Disclosure of Invention The application mainly aims to provide a printing and cutting integrated processing method, printing and cutting integrated processing equipment and a storage medium, and aims to solve the technical problem of printing and cutting dislocation caused by nonlinear deformation in the conventional flexible material printing and cutting processing. In order to achieve the above purpose, the application provides a printing and cutting integrated processing method, which is applied to a printing and cutting integrated machine, wherein the printing and cutting integrated machine is provided with a printing component and a cutting component, the printing component and the cutting component are arranged on the same motion mechanism and driven by the same servo motor to establish a unified machine coordinate system, and the method comprises the following steps: Driving the printing assembly to output a printing layer of a material to be cut according to the material processing parameters, wherein the printing layer comprises positioning marks and material patterns; Acquiring actual coordinates and theoretical coordinates of the positioning marks in the unified machine coordinate system, and calculating nonlinear offset of the printing layer based on the actual coordinates and the theoretical coordinates; Determining fixed position offset of the printing component and the cutting component in the unified machine coordinate system, and dynamically compensating a preset cutting path through the fixed position offset and the nonlinear offset to generate a compensating cutting path; Controlling the cutting assembly to cut the material to be cut along the compensation cutting path; And in the processing process, iteratively updating the compensation parameters of the nonlinear offset according to the cutting feedback data and the visual feedback data acquired in real time until the printing and cutting of the material pattern are completed. In one embodiment, the step of obtaining the actual coordinates and the theoretical coordinates of the positioning mark in the unified machine coordinate system, and calculating the nonlinear
