Embodiment Construction
[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0030] The present invention recognizes sheet material by DM two-dimensional code and utilizes the method for automatic retrieval of macro program to comprise the following steps:
[0031] 1. Process improvement in sheet metal identification—add DM QR code to DXF file;
[0032] Decompile and sign the existing DM two-dimensional code transcoding library file (written in C#) to generate a COM component that can be called by SolidWorks. The method is as follows:
[0033] (1) Open the SDK command window and create a new random key pair;
[0034] (2) Decompile the target assembly;
[0035] (3) Recompile with strong naming parameters;
[0036] (4) Verify signature information.
[0037] see figure 1 , convert the sheet metal part code (such as 6598.0201.00010001) into a 0-1 matrix, draw the DM QR code in SolidWorks according to the matrix, and output the DXF fi...

The invention discloses a method for recognizing plate materials through DM two-dimensional codes and carrying out automatic retrieval by utilizing macro programs. The method comprises the following steps of: 1, generating a COM assembly which can be called by SolidWorks through an existing DM two-dimensional code transcoding library file; 2, converting a code of a sheet metal part to a 0-1 matrix; 3, drawing a DM two-dimensional code in the SolidWorks and outputting a DXF file for laser cutting according to the obtained matrix; 4, marking a plate material through the DM two-dimensional code in the laser blanking process; 5, traversing all the sheet metal part drawings / assembly drawings in a general list of sheet metal part drawings / assembly drawings so as to form a code-part name mapping table or a code-assembly name mapping table; and 6, scanning the DM two-dimensional code on the surface of the plate material, searching a corresponding sheet metal part drawing / assembly drawing through a macro program, and finally opening the sheet metal part drawing / assembly drawing in a top view manner. The method disclosed by the invention can be used for replacing the artificial recognition of the plate materials.
Description
technical field [0001] The invention relates to the field of sheet metal production, in particular to a method for identifying sheets through DM two-dimensional codes and using macro programs for automatic retrieval, reducing the time spent manually searching for sheet metal part drawings / assembly drawings. Background technique [0002] The process flow of sheet metal includes drawing dismantling, DXF typesetting, laser blanking, sheet sorting, sheet identification, bending, riveting, tapping, welding, grinding, sandblasting (pretreatment) and spraying. Among them, sheet identification, bending, welding and other processes take up a lot of time, especially a large number of sheets produced after laser blanking require manual identification, which seriously reduces production efficiency. Therefore, it is necessary to optimize those processes with greater room for efficiency improvement to meet the growing demand of sheet metal products business. [0003] In the existing proc...
