Problems solved by technology

[0003] Most of the existing manufacturing management systems digitize the production process through manual input of workpiece information. This method can digitally input the bom table exported by the design software, but it relies on third-party plug-ins, and some data still needs to be manually input. Manual association is required, and the operation is cumbersome

Abstract

The invention discloses a digital conversion method for a PDF drawing in the sheet metal industry. The digital conversion method is characterized by comprising the following steps: S100, initializinga container; S200, analyzing the drawing data, including: S201, splitting each set of PDF drawing into a plurality of single pages and forming a PDF drawing page list; S202, judging whether the page number of a single page in the PDF picture page list is greater than 0 or not; if so, executing the step S203; otherwise, ending the process; S203, sequentially obtaining current graph pages from the PDF graph page list; S204, acquiring characters of the current picture page; S205, searching a character string corresponding to the basic material page identifier in the characters of the current picture page; S206, judging whether the search is successful or not; if so, executing the step S207; otherwise, executing the step S208; S207, analyzing the basic material, and executing the step S209; S208, analyzing the derivative material; S209, judging whether an unprocessed single page still exists or not; if so, executing the step S203; otherwise, executing the step S300; S300, verifying the quantity of the materials; S400, exporting an error log; S500, packaging the digital drawing.

Description

technical field [0001] The invention belongs to the field of digitization of production management, and relates to a digitization conversion method for PDF drawings in the sheet metal industry. Background technique [0002] In the sheet metal production and processing industry, drawings are usually a key production material for conveying product form, production process, and production requirements. In order to facilitate the circulation of drawings, the traditional method is to convert the drawings into PDF format for transmission and sharing. In the actual production line, the drawings in PDF format are usually printed directly and circulated as paper files. This method is feasible in the period of human control and when the drawings are fixed, such as mechanical processing drawings, but under the requirements of digital production, product parts, processes, drawings, etc. need to be stored and distributed in digital form and circulation, and the drawings need to reflect ...
