Problems solved by technology

In this case, the method of manually teaching programming through the teaching box requires frequent movement of the welding torch to locate the position of the solder joints. The programming process is cumbersome, the programming efficiency is low, the position accuracy is low, and the proficiency of the programmer is limited. A series of problems, so how to improve the speed and accuracy of programming has become a difficult problem for major manufacturers

Embodiment Construction

[0035] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] The design concept of the present invention is as follows: use the processing function of graphics and images that the robot has (this belongs to the conventional technology in the field of robot programming), and in the programming process, the Gerber file is imported into the programming file. The Gerber file contains Gerber graphics information, which is converted into a file format that the programming file can support after being processed by the code in the software, and then imported.

[0037] Gerber file is an international standard photo-painting format file, which is widely used in PCB board manufacturing and electronic assembly industry. It contains two formats, RS-274-D and RS-274-X, among which RS-274-D is called the basic GERBER format, and a D code file must be attached at the same time to fully describe a graphic; RS-...

Abstract

The invention discloses a method for improving programming speed and precision of a soldering robot by using a Gerber file. The method comprises the following steps of: (1) introducing the Gerber file into a programming file; (2) setting Gerber parameters; (3) analyzing the Gerber file, and obtaining a welding layer in a Gerber graph; (4) processing a Gerber welding graph, and constructing a relation between graph coordinates and object coordinates; (5) selecting a welding point to be welded on the processed Gerber welding graph, calculating actual physical coordinates corresponding to the graph coordinates according to the coordinate conversion relation obtained in step (4), and moving a welding nozzle to a position with the actual physical coordinates; and (6) finding actual physical coordinates of 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 a printed circuit board (PCB) can be accurately calculated and can be accurately compensated; the welding precision is improved; and during welding, a phenomenon of inaccurate welding caused by deflection of the position of the PCB can be avoided.

Description

technical field [0001] The invention relates to the technical field of automatic soldering robot automatic welding, which is used for welding PCB boards, in particular to a method for improving the programming speed and precision of a soldering robot by using Gerber files. Background technique [0002] Common robot application modes in the industrial field are all in accordance with figure 1 The process shown is carried out. 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. production efficiency. Its appearance will greatly reduce production costs and transform manual work into automatic operation of machines. Users can also adjust various parameters of the robot according to different welding pr...
