Embodiment Construction

[0032] The technical idea of ​​the present invention is: in the programming process, the CAD file of the PCB board is imported into the programming file. CAD files refer to: files containing CAD graphics information, CAD graphics are converted and generated by CAD files through software code processing; programming files can convert CAD graphics information contained in CAD files through software code processing into a file format supported by the program file, and then import it. The import method is: start the soldering robot programming software, and select the corresponding CAD file, then the CAD file analysis function module inside the soldering robot will analyze the CAD file line by line according to the standard CAD file format, and convert it It is a standard image file (such as bmp, jpg, etc.).

[0033] By importing CAD files, the included CAD graphic information can generate corresponding CAD graphics and display them in the program file. The graphics are further ...

Abstract

The invention discloses a method for improving programming speed and precision of a soldering robot by using a computer-aided design (CAD) file. The method comprises the following steps of: (1) introducing the CAD file comprising a printed circuit board (PCB) into a programming file; (2) analyzing the CAD file, and converting the programming file into a supportable file format; (3) generating a corresponding CAD graph in the programming file, wherein the graph comprises precise position information of all the welding disks; (4) processing the generated CAD graph, and constructing a relation between graph coordinates and object coordinates; (5) selecting a welding point to be welded on the processed CAD graph, obtaining actual physical coordinates according to the coordinate conversion relation obtained in step (4), and moving a welding nozzle to a position with the actual physical coordinates so as to perform parameter setting and welding; and (6) finding other welding points by the method in step (5), and welding. By adopting the method, a camera is not required to shoot a thumbnail, and the programming time is shortened; the rotating angle of the PCB can be accurately calculated and can be compensated; and the welding precision is improved.

Description

technical field [0001] The invention relates to an automatic welding technology of an automatic soldering robot, which is used for welding a PCB board, in particular to a method for improving the programming speed and precision of a soldering robot by using a CAD file. Background technique [0002] Automatic soldering robot is an automation system widely used in major factories and enterprises in China. It has the characteristics of stable performance, large working space, fast movement speed and strong load capacity. The welding quality is obviously better than manual welding, which greatly improves the welding operation. Its appearance will greatly reduce production costs and transform manual work into automatic machine operation. Users can also adjust various parameters of the robot according to different welding processes to make the welding effect better. [0003] For automatic soldering robots, controlling automatic soldering through programming is a very important li...
